Subject: x86/syscalls: Split the x32 syscalls into their own table

For unfortunate historical reasons, the x32 syscalls and the x86_64
syscalls are not all numbered the same.  As an example, ioctl() is nr 16 on
x86_64 but 514 on x32.

This has potentially nasty consequences, since it means that there are two
valid RAX values to do ioctl(2) and two invalid RAX values.  The valid
values are 16 (i.e. ioctl(2) using the x86_64 ABI) and (514 | 0x40000000)
(i.e. ioctl(2) using the x32 ABI).

The invalid values are 514 and (16 | 0x40000000).  514 will enter the
"COMPAT_SYSCALL_DEFINE3(ioctl, ...)" entry point with in_compat_syscall()
and in_x32_syscall() returning false, whereas (16 | 0x40000000) will enter
the native entry point with in_compat_syscall() and in_x32_syscall()
returning true.  Both are bogus, and both will exercise code paths in the
kernel and in any running seccomp filters that really ought to be
unreachable.

Splitting out the x32 syscalls into their own tables, allows both bogus
invocations to return -ENOSYS.  I've checked glibc, musl, and Bionic, and
all of them appear to call syscalls with their correct numbers, so this
change should have no effect on them.

There is an added benefit going forward: new syscalls that need special
handling on x32 can share the same number on x32 and x86_64.  This means
that the special syscall range 512-547 can be treated as a legacy wart
instead of something that may need to be extended in the future.

Also add a selftest to verify the new behavior.

Subject: x86/mpx: Remove selftests Makefile entry

MPX is being removed from the kernel due to a lack of support in the
toolchain going forward (gcc).

This is the smallest possible patch to fix some issues that have been
reported around running the MPX selftests.  It it would also have been part
of any removal series, it is offered first.

Subject: x86/mpx: Remove selftests themselves

MPX is being removed from the kernel due to a lack of support in the
toolchain going forward (gcc).

Remove the x86 selftests since they have been causing some issues because
of their propensity to do some debug-aiding tracepoint mucking.

Subject: x86: Remove X86_FEATURE_MFENCE_RDTSC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

AMD and Intel both have serializing lfence (X86_FEATURE_LFENCE_RDTSC).
They've both had it for a long time, and AMD has had it enabled in Linux
since Spectre v1 was announced.

Back then, there was a proposal to remove the serializing mfence feature
bit (X86_FEATURE_MFENCE_RDTSC), since both AMD and Intel have
serializing lfence.  At the time, it was (ahem) speculated that some
hypervisors might not yet support its removal, so it remained for the
time being.

Now a year-and-a-half later, it should be safe to remove.

I asked Andrew Cooper about whether it's still needed:

  So if you're virtualised, you've got no choice in the matter.  lfence
  is either dispatch-serialising or not on AMD, and you won't be able to
  change it.

  Furthermore, you can't accurately tell what state the bit is in, because
  the MSR might not be virtualised at all, or may not reflect the true
  state in hardware.  Worse still, attempting to set the bit may not be
  successful even if there isn't a fault for doing so.

  Xen sets the DE_CFG bit unconditionally, as does Linux by the looks of
  things (see MSR_F10H_DECFG_LFENCE_SERIALIZE_BIT).  ISTR other hypervisor
  vendors saying the same, but I don't have any information to hand.

  If you are running under a hypervisor which has been updated, then
  lfence will almost certainly be dispatch-serialising in practice, and
  you'll almost certainly see the bit already set in DE_CFG.  If you're
  running under a hypervisor which hasn't been patched since Spectre,
  you've already lost in many more ways.

  I'd argue that X86_FEATURE_MFENCE_RDTSC is not worth keeping.

So remove it.  This will reduce some code rot, and also make it easier
to hook barrier_nospec() up to a cmdline disable for performance
raisins, without having to need an alternative_3() macro.

Subject: libbpf: provide more helpful message on uninitialized global var

When BPF program defines uninitialized global variable, it's put into
a special COMMON section. Libbpf will reject such programs, but will
provide very unhelpful message with garbage-looking section index.

This patch detects special section cases and gives more explicit error
message.

Subject: usbip: tools: fix GCC8 warning for strncpy

GCC8 started emitting warning about using strncpy with number of bytes
exactly equal destination size which could lead to non-zero terminated
string being copied. Use "SYSFS_PATH_MAX - 1" & "SYSFS_BUS_ID_SIZE - 1"
as number of bytes to ensure name is always zero-terminated.

Subject: leds: core: Add support for composing LED class device names

Add generic support for composing LED class device name. The newly
introduced led_compose_name() function composes device name according
to either <color:function> or <devicename:color:function> pattern,
depending on the configuration of initialization data.

Backward compatibility with in-driver hard-coded LED class device
names is assured thanks to the default_label and devicename properties
of newly introduced struct led_init_data.

In case none of the aforementioned properties was found, then, for OF
nodes, the node name is adopted for LED class device name.

At the occassion of amending the Documentation/leds/leds-class.txt
unify spelling: colour -> color.

Alongside these changes added is a new tool - tools/leds/get_led_device_info.sh.
The tool allows retrieving details of a LED class device's parent device,
which proves that using vendor or product name for devicename part
of LED name doesn't convey any added value since that information had been
already available in sysfs. The script performs also basic validation
of a LED class device name.

@@ -43,9 +43,73 @@ LED Device Naming
 
 Is currently of the form:
 
-	"devicename:colour:function"
-
-There have been calls for LED properties such as colour to be exported as
+	"devicename:color:function"
+
+- devicename:
+        it should refer to a unique identifier created by the kernel,
+        like e.g. phyN for network devices or inputN for input devices, rather
+        than to the hardware; the information related to the product and the bus
+        to which given device is hooked is available in sysfs and can be
+        retrieved using get_led_device_info.sh script from tools/leds; generally
+        this section is expected mostly for LEDs that are somehow associated with
+        other devices.
+
+- color:
+        one of LED_COLOR_ID_* definitions from the header
+        include/dt-bindings/leds/common.h.
+
+- function:
+        one of LED_FUNCTION_* definitions from the header
+        include/dt-bindings/leds/common.h.
+
+If required color or function is missing, please submit a patch
+to linux-leds@vger.kernel.org.
+
+It is possible that more than one LED with the same color and function will
+be required for given platform, differing only with an ordinal number.
+In this case it is preferable to just concatenate the predefined LED_FUNCTION_*
+name with required "-N" suffix in the driver. fwnode based drivers can use
+function-enumerator property for that and then the concatenation will be handled
+automatically by the LED core upon LED class device registration.
+
+LED subsystem has also a protection against name clash, that may occur
+when LED class device is created by a driver of hot-pluggable device and
+it doesn't provide unique devicename section. In this case numerical
+suffix (e.g. "_1", "_2", "_3" etc.) is added to the requested LED class
+device name.
+
+There might be still LED class drivers around using vendor or product name
+for devicename, but this approach is now deprecated as it doesn't convey
+any added value. Product information can be found in other places in sysfs
+(see tools/leds/get_led_device_info.sh).
+
+Examples of proper LED names:
+
+  - "red:disk"
+  - "white:flash"
+  - "red:indicator"
+  - "phy1:green:wlan"
+  - "phy3::wlan"
+  - ":kbd_backlight"
+  - "input5::kbd_backlight"
+  - "input3::numlock"
+  - "input3::scrolllock"
+  - "input3::capslock"
+  - "mmc1::status"
+  - "white:status"
+
+get_led_device_info.sh script can be used for verifying if the LED name
+meets the requirements pointed out here. It performs validation of the LED class
+devicename sections and gives hints on expected value for a section in case
+the validation fails for it. So far the script supports validation
+of associations between LEDs and following types of devices:
+
+        - input devices
+        - ieee80211 compliant USB devices
+
+The script is open to extensions.
+
+There have been calls for LED properties such as color to be exported as
 individual led class attributes. As a solution which doesn't incur as much
 overhead, I suggest these become part of the device name. The naming scheme
 above leaves scope for further attributes should they be needed. If sections

Subject: selftests/bpf: Add selftests for bpf_perf_event_output

Software event output is only enabled by a few prog types.
This test is to ensure that all supported types are enabled for
bpf_perf_event_output successfully.

Subject: selftests/bpf: support BPF_FLOW_DISSECTOR_F_PARSE_1ST_FRAG

bpf_flow.c: exit early unless BPF_FLOW_DISSECTOR_F_PARSE_1ST_FRAG is
passed in flags. Also, set ip_proto earlier, this makes sure we have
correct value with fragmented packets.

Add selftest cases to test ipv4/ipv6 fragments and skip eth_get_headlen
tests that don't have BPF_FLOW_DISSECTOR_F_PARSE_1ST_FRAG flag.

eth_get_headlen calls flow dissector with
BPF_FLOW_DISSECTOR_F_PARSE_1ST_FRAG flag so we can't run tests that
have different set of input flags against it.

v2:
 * sefltests -> selftests (Willem de Bruijn)
 * Reword a comment about eth_get_headlen flags (Song Liu)

Subject: bpf/flow_dissector: support ipv6 flow_label and
 BPF_FLOW_DISSECTOR_F_STOP_AT_FLOW_LABEL

Add support for exporting ipv6 flow label via bpf_flow_keys.
Export flow label from bpf_flow.c and also return early when
BPF_FLOW_DISSECTOR_F_STOP_AT_FLOW_LABEL is passed.

Subject: crypto: Remove orphan tools/crypto directory

The directory tools/crypto and the only file under it never gets
built anywhere.  This program should instead be incorporated into
one of the existing user-space projects, crconf or libkcapi.

Subject: libbpf: fix erroneous multi-closing of BTF FD

Libbpf stores associated BTF FD per each instance of bpf_program. When
program is unloaded, that FD is closed. This is wrong, because leads to
a race and possibly closing of unrelated files, if application
simultaneously opens new files while bpf_programs are unloaded.

It's also unnecessary, because struct btf "owns" that FD, and
btf__free(), called from bpf_object__close() will close it. Thus the fix
is to never have per-program BTF FD and fetch it from obj->btf, when
necessary.

Fixes: 2993e0515bb4 ("tools/bpf: add support to read .BTF.ext sections")

Subject: selftests/bpf: prevent headers to be compiled as C code

Apprently listing header as a normal dependency for a binary output
makes it go through compilation as if it was C code. This currently
works without a problem, but in subsequent commits causes problems for
differently generated test.h for test_progs. Marking those headers as
order-only dependency solves the issue.

Subject: selftests/bpf: revamp test_progs to allow more control

Refactor test_progs to allow better control on what's being run.
Also use argp to do argument parsing, so that it's easier to keep adding
more options.

Add ability to specify either test number or test name substring to
narrow down a set of test to run.

Usage:
sudo ./test_progs -n 1
sudo ./test_progs -t attach_probe

Subject: libbpf: return previous print callback from libbpf_set_print

By returning previously set print callback from libbpf_set_print, it's
possible to restore it, eventually. This is useful when running many
independent test with one default print function, but overriding log
verbosity for particular subset of tests.

Subject: selftest/bpf: centralize libbpf logging management for test_progs

Make test_progs test runner own libbpf logging. Also introduce two
levels of verbosity: -v and -vv. First one will be used in subsequent
patches to enable test log output always. Second one increases verbosity
level of libbpf logging further to include debug output as well.

Subject: selftests/bpf: abstract away test log output

This patch changes how test output is printed out. By default, if test
had no errors, the only output will be a single line with test number,
name, and verdict at the end, e.g.:

  #31 xdp:OK

If test had any errors, all log output captured during test execution
will be output after test completes.

It's possible to force output of log with `-v` (`--verbose`) option, in
which case output won't be buffered and will be output immediately.

To support this, individual tests are required to use helper methods for
logging: `test__printf()` and `test__vprintf()`.

From 3a516a0a3a7b21ec038db83ffb0d3cddc42514c9 Mon Sep 17 00:00:00 2001
From: Andrii Nakryiko <andriin@fb.com>
Date: Sat, 27 Jul 2019 20:25:29 -0700
Subject: selftests/bpf: add sub-tests support for test_progs

Allow tests to have their own set of sub-tests. Also add ability to do
test/subtest selection using `-t <test-name>/<subtest-name>` and `-n
<test-nums-set>/<subtest-nums-set>`, as an extension of existing -t/-n
selector options. For the <test-num-set> format: it's a comma-separated
list of either individual test numbers (1-based), or range of test
numbers. E.g., all of the following are valid sets of test numbers:
  - 10
  - 1,2,3
  - 1-3
  - 5-10,1,3-4

'/<subtest' part is optional, but has the same format. E.g., to select
test #3 and its sub-tests #10 through #15, use: -t 3/10-15.

Similarly, to select tests by name, use `-t verif/strobe`:

  $ sudo ./test_progs -t verif/strobe
  #3/12 strobemeta.o:OK
  #3/13 strobemeta_nounroll1.o:OK
  #3/14 strobemeta_nounroll2.o:OK
  #3 bpf_verif_scale:OK
  Summary: 1/3 PASSED, 0 FAILED

Example of using subtest API is in the next patch, converting
bpf_verif_scale.c tests to use sub-tests.

Subject: selftests/bpf: convert bpf_verif_scale.c to sub-tests API

Expose each BPF verifier scale test as individual sub-test to allow
independent results output and test selection.

Test run results now look like this:

Subject: perf bpf: Do not attach a BPF prog to a tracepoint if its name starts
 with !
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With BPF_MAP_TYPE_PROG_ARRAY + bpf_tail_call() we want to have BPF
programs, i.e. functions in a object file that perf's BPF loader
shouldn't try to attach to anything, i.e. "!syscalls:sys_enter_open"
should just stay there, not be attached to a tracepoint with that name,
it'll be used by, for instance, 'perf trace' to associate with syscalls
that copy, in addition to the syscall raw args, a filename pointed by
the first arg, i.e. multiple syscalls that need copying the same pointer
arg in the same way, as a filename, for instance, will share the same
BPF program/function.

Right now when perf's BPF loader sees a function with a name
"sys:name" it'll look for a tracepoint and will associate that BPF
program with it, say:

  SEC("raw_syscalls:sys_enter")
  int sys_enter(struct syscall_enter_args *args)
  {
     //SNIP
  }

Will crate a perf_evsel tracepoint event and then associate with it that
BPF program.

This convention at some point will switch to the one used by the BPF
loader in libbpf, but to experiment with BPF_MAP_TYPE_PROG_ARRAY in
'perf trace' lets do this, that will not require changing too much
stuff.

Subject: perf trace: Add BPF handler for unaugmented syscalls
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Will be used to assign to syscalls that don't need augmentation, i.e.
those with just integer args.

All syscalls will be in a BPF_MAP_TYPE_PROG_ARRAY, and the
bpf_tail_call() keyed by the syscall id will either find nothing in
place, which means the syscall is being filtered, or a function that
will either add things like filenames to the ring buffer, right after
the raw syscall args, or be this unaugmented handler that will just
return 1, meaning don't filter the original
raw_syscalls:sys_{enter,exit} tracepoint.

For now it is not really being used, this is just leg work to break the
patch into smaller pieces.

It introduces a trace__find_bpf_program_by_title() helper that in turn
uses libbpf's bpf_object__find_program_by_title() on the BPF object with
the __augmented_syscalls__ map. "title" is how libbpf calls the SEC()
argument for functions, i.e. the ELF section that follows a convention
to specify what BPF program (a function with this SEC() marking) should
be connected to which tracepoint, kprobes, etc.

In perf anything that is of the form SEC("sys:event_name") will be
connected to that tracepoint by perf's BPF loader.

In this case its something that will be bpf_tail_call()ed from either
the "raw_syscalls:sys_enter" or "raw_syscall:sys_exit" tracepoints, so
its named "!raw_syscalls:unaugmented" to convey that idea, i.e. its not
going to be directly attached to a tracepoint, thus it starts with a
"!".

Subject: perf trace: Allow specifying the bpf prog to augment specific
 syscalls
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is a step in the direction of being able to use a
BPF_MAP_TYPE_PROG_ARRAY to handle syscalls that need to copy pointer
payloads in addition to the raw tracepoint syscall args.

There is a first example in
tools/perf/examples/bpf/augmented_raw_syscalls.c for the 'open' syscall.

Next step is to introduce the prog array map and use this 'open'
augmenter, then use that augmenter in other syscalls that also only copy
the first arg as a string, and then show how to use with a syscall that
reads more than one filename, like 'rename', etc.

Subject: perf trace: Put the per-syscall entry/exit prog_array BPF map
 infrastructure in place
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I.e. look for "syscalls_sys_enter" and "syscalls_sys_exit" BPF maps of
type PROG_ARRAY and populate it with the handlers as specified per
syscall, for now only 'open' is wiring it to something, in time all
syscalls that need to copy arguments entering a syscall or returning
from one will set these to the right handlers, reusing when possible
pre-existing ones.

Next step is to use bpf_tail_call() into that.

Subject: perf trace: Handle raw_syscalls:sys_enter just like the BPF_OUTPUT
 augmented event
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

So, we use a PERF_COUNT_SW_BPF_OUTPUT to output the augmented sys_enter
payload, i.e. to output more than just the raw syscall args, and if
something goes wrong when handling an unfiltered syscall, we bail out
and just return 1 in the bpf program associated with
raw_syscalls:sys_enter, meaning, don't filter that tracepoint, in which
case what will appear in the perf ring buffer isn't the BPF_OUTPUT
event, but the original raw_syscalls:sys_enter event with its normal
payload.

Now that we're switching to using a bpf_tail_call +
BPF_MAP_TYPE_PROG_ARRAY we're going to use this in the common case, so a
bug where raw_syscalls:sys_enter wasn't being handled by
trace__sys_enter() surfaced and for  that case, instead of using the
strace-like augmenter (trace__sys_enter()), we continued to use the
normal generic tracepoint handler:

  (gdb) p evsel
  $2 = (struct perf_evsel *) 0xc03e40
  (gdb) p evsel->name
  $3 = 0xbc56c0 "raw_syscalls:sys_enter"
  (gdb) p ((struct perf_evsel *) 0xc03e40)->name
  $4 = 0xbc56c0 "raw_syscalls:sys_enter"
  (gdb) p ((struct perf_evsel *) 0xc03e40)->handler
  $5 = (void *) 0x495eb3 <trace__event_handler>

This resulted in this:

     0.027 raw_syscalls:sys_enter:NR 12 (0, 7fcfcac64c9b, 4d, 7fcfcac64c9b, 7fcfcac6ce00, 19)
     ... [continued]: brk())                = 0x563b88677000

I.e. only the sys_exit tracepoint was being properly handled, but since
the sys_enter went to the generic trace__event_handler() we printed it
using libtraceevent's formatter instead of 'perf trace's strace-like
one.

Fix it by setting trace__sys_enter() as the handler for
raw_syscalls:sys_enter and setup the tp_field tracepoint field
accessors.

Now, to test it we just make raw_syscalls:sys_enter return 1 right after
checking if the pid is filtered, making it not use
bpf_perf_output_event() but rather ask for the tracepoint not to be
filtered and the result is the expected one:

  brk(NULL)                               = 0x556f42d6e000

I.e. raw_syscalls:sys_enter returns 1, gets handled by
trace__sys_enter() and gets it combined with the raw_syscalls:sys_exit
in a strace-like way.

I.e. for a syscall that has its second argument being a string, its
difficult these days to find 'open' being used in the wild :-)

Subject: perf augmented_raw_syscalls: Switch to using BPF_MAP_TYPE_PROG_ARRAY
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Trying to control what arguments to copy, which ones were strings, etc
all from userspace via maps went nowhere, lots of difficulties to get
the verifier satisfied, so use what the fine BPF guys designed for such
a syscall handling mechanism: bpf_tail_call + BPF_MAP_TYPE_PROG_ARRAY.

The series leading to this should have explained it thoroughly, but the
end result, explained via gdb should help understand this:

Now its a matter of automagically assigning the BPF programs copying
syscall arg pointers to functions that are "open"-like (i.e. that need
only the first syscall arg copied as a string), or "openat"-like (2nd
arg, etc).

End result in tool output:

Subject: perf augmented_raw_syscalls: Support copying two string syscall args
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Starting with the renameat and renameat2 syscall, that both receive as
second and fourth parameters a pathname:

  # perf trace -e rename* mv one ANOTHER
  LLVM: dumping /home/acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.o
  mv: cannot stat 'one': No such file or directory
  renameat2(AT_FDCWD, "one", AT_FDCWD, "ANOTHER", RENAME_NOREPLACE) = -1 ENOENT (No such file or directory)
  #

Since the per CPU scratch buffer map has space for two maximum sized
pathnames, the verifier is satisfied that there will be no overrun.

 array

I.e. just look for "!syscalls:sys_enter_" or "exit_" plus the syscall
name, that way we need just to add entries to the
augmented_raw_syscalls.c BPF source to add handlers.

We already had a beautifier for an augmented sockaddr payload, but that
was when we were hooking on each syscalls:sys_enter_foo tracepoints,
since now we're almost doing that by doing a tail call from
raw_syscalls:sys_enter, its almost the same, we can reuse it straight
away.

Subject: perf trace beauty: Disable fd->pathname when close() not enabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As we invalidate the fd->pathname table in the SCA_CLOSE_FD beautifier,
if we don't have it we may end up keeping an fd->pathname association
that then gets misprinted.

The previous behaviour continues when the close() syscall is enabled,
which may still be a a problem if we lose records (i.e. we may lose a
'close' record and then get that fd reused by socket()) but then the
tool will notify that records are being lost and the user will be warned
that some of the heuristics will fall apart.

Subject: perf trace: Forward error codes when trying to read syscall info
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We iterate thru the syscall table produced from the kernel syscall
tables reading info, propagate the error and add to the debug message.

This helps in fixing further bugs, such as failing to read the
"sendfile" syscall info when it really should try the aliasm
"sendfile64".

  Problems reading syscall 40: 2 (No such file or directory)(sendfile) information

  # grep sendfile /tmp/build/perf/arch/x86/include/generated/asm/syscalls_64.c
	[40] = "sendfile",
  #

I.e. in the tracefs format file for the syscall tracepoints we have it
as sendfile64:

  # find /sys -type f -name format | grep sendfile
  /sys/kernel/debug/tracing/events/syscalls/sys_enter_sendfile64/format
  /sys/kernel/debug/tracing/events/syscalls/sys_exit_sendfile64/format
  #

But as "sendfile" in the file used to build the syscall table used in
perf:

  $ grep sendfile arch/x86/entry/syscalls/syscall_64.tbl
  40	common	sendfile		__x64_sys_sendfile64
  $

So we need to add, in followup patches, aliases in 'perf trace' syscall
data structures to cope with thie.

Subject: perf trace: Mark syscall ids that are not allocated to avoid
 unnecessary error messages
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There are holes in syscall tables with IDs not associated with any
syscall, mark those when trying to read information for syscalls, which
could happen when iterating thru all syscalls from 0 to the highest
numbered syscall id.

Subject: perf trace: Preallocate the syscall table
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We'll continue reading its details from tracefs as we need it, but
preallocate the whole thing otherwise we may realloc and end up with
pointers to the previous buffer.

I.e. in an upcoming algorithm we'll look for syscalls that have function
signatures that are similar to a given syscall to see if we can reuse
its BPF augmenter, so we may be at syscall 42, having a 'struct syscall'
pointing to that slot in trace->syscalls.table[] and try to read the
slot for an yet unread syscall, which would realloc that table to read
the info for syscall 43, say, which would trigger a realoc of
trace->syscalls.table[], and then the pointer we had for syscall 42
would be pointing to the previous block of memory. b00m.

Subject: perf trace: Reuse BPF augmenters from syscalls with similar args
 signature
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We have an augmenter for the "open" syscall, which has just one pointer,
in the first argument, a "const char *", so any other syscall that has
just one pointer and that is the first can reuse the "open" BPF
augmenter program.

Even more, syscalls that get two pointers with the first being a string
can reuse "open"'s BPF augmenter till we have an augmenter that better
matches that syscall with two pointers.

With this the few augmenters we have, for open (first arg is a string),
openat (2nd arg is a string), renameat (2nd and 4th are strings) can be
reused by a lot of syscalls, ditto for "bind" reusing "connect" because
both have the 2nd argument as a sockaddr and the 3rd as its len.

Lets see how this makes the "bind" syscall reuse the "connect" BPF prog
augmenter found in tools/perf/examples/bpf/augmented_raw_syscalls.c:

  # perf trace -e bind,connect systemctl restart sshd
  connect(3, { .family: PF_LOCAL, path: /run/systemd/private }, 23) = 0
  #

Oh, it just connects to some daemon, so we better do it system wide and then
stop/start sshd:

  # perf trace -e bind,connect

Subject: perf trace: Add "sendfile64" alias to the "sendfile" syscall
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We were looking in tracefs for:

  /sys/kernel/debug/tracing/events/syscalls/sys_enter_sendfile/format when

what is there is just

  /sys/kernel/debug/tracing/events/syscalls/sys_enter_sendfile/format

Its the same id, 40 in x86_64, so just add an alias and let the existing
logic take care of that.

Subject: perf stat: Move loaded out of struct perf_counts_values

Because we will make struct perf_counts_values public in following
patches and 'loaded' is implementation related.

No functional change is expected.

From 9749b90e566ca1a235fc8e2118f99c5690969342 Mon Sep 17 00:00:00 2001
From: Jiri Olsa <jolsa@kernel.org>
Date: Sun, 21 Jul 2019 13:23:50 +0200
Subject: perf tools: Rename struct thread_map to struct perf_thread_map

Rename struct thread_map to struct perf_thread_map, so it could be part
of libperf.

From 32dcd021d004038ca12ac17319da5aa4756e9312 Mon Sep 17 00:00:00 2001
From: Jiri Olsa <jolsa@kernel.org>
Date: Sun, 21 Jul 2019 13:23:51 +0200
Subject: perf evsel: Rename struct perf_evsel to struct evsel

Rename struct perf_evsel to struct evsel, so we don't have a name clash
when we add struct perf_evsel in libperf.

Committer notes:

Added fixes for arm64, provided by Jiri.

From 63503dba87acfab49280d3b05df6705a6f327e8a Mon Sep 17 00:00:00 2001
From: Jiri Olsa <jolsa@kernel.org>
Date: Sun, 21 Jul 2019 13:23:52 +0200
Subject: perf evlist: Rename struct perf_evlist to struct evlist

Rename struct perf_evlist to struct evlist, so we don't have a name
clash when we add struct perf_evlist in libperf.

Committer notes:

Added fixes to build on arm64, from Jiri and from me
(tools/perf/util/cs-etm.c)

From c12995a55474e1cefac52da38c7fc47c024de067 Mon Sep 17 00:00:00 2001
From: Jiri Olsa <jolsa@kernel.org>
Date: Sun, 21 Jul 2019 13:23:56 +0200
Subject: perf evlist: Rename perf_evlist__delete() to evlist__delete()

Rename perf_evlist__delete() to evlist__delete(), so we don't have a
name clash when we add perf_evlist__delete() in libperf.

Subject: perf evsel: Rename perf_evsel__delete() to evsel__delete()

Remame perf_evsel__delete() to evsel__delete(), so we don't have a name
clash when we add perf_evsel__delete() in libperf.

Also renaming perf_evsel__delete_priv() to evsel__delete_priv().

Subject: perf evlist: Rename perf_evlist__disable() to evlist__disable()

Rename perf_evlist__disable() to evlist__disable(), so we don't have a
name clash when we add perf_evlist__disable() in libperf.

Subject: libperf: Make libperf.a part of the perf build

Add an empty libperf.a under tools/perf/lib and link it with perf.

It can also be built separately with:

  $ cd tools/perf/lib && make
    CC       core.o
    LD       libperf-in.o
    AR       libperf.a
    LINK     libperf.so

Committer testing:

  $ make O=/tmp/build/perf -C tools/perf/lib/
  make: Entering directory '/home/acme/git/perf/tools/perf/lib'
    LINK     /tmp/build/perf/libperf.so
  make: Leaving directory '/home/acme/git/perf/tools/perf/lib'
  $ ls -la /tmp/build/perf/libperf.so
  -rwxrwxr-x. 1 acme acme 16232 Jul 22 15:30 /tmp/build/perf/libperf.so
  $ file /tmp/build/perf/libperf.so

  $ git status tools/perf

  $
  $ ls -lart tools/perf/lib/

  drwxrwxr-x.  2 acme acme 4096 Jul 22 15:29 .
  $

Committer notes:

Need to add -I$(srctree)/tools/arch/$(ARCH)/include/uapi
-I$(srctree)/tools/include/uapi to tools/perf/lib/Makefile's INCLUDE
variable to pick up the latest versions of kernel headers, even in older
systems, this is in line with what is in tools/lib/bpf/Makefile.

Date: Sun, 21 Jul 2019 13:24:11 +0200
Subject: libperf: Add build version support

Add a shared library version, generating the following files:

  $ ll tools/perf/lib/libperf.so*
  libperf.so -> libperf.so.0.0.1
  libperf.so.0 -> libperf.so.0.0.1
  libperf.so.0.0.1

Committer testing:

One has to build just libbperf to get this, building perf so far doesn't
trigger this, i.e. I tried:

  $ make O=/tmp/build/perf -C tools/perf

And the files above were not created, so one has to do:

  $ make O=/tmp/build/perf -C tools/perf/lib/
  make: Entering directory '/home/acme/git/perf/tools/perf/lib'
    LINK     /tmp/build/perf/libperf.so.0.0.1
  make: Leaving directory '/home/acme/git/perf/tools/perf/lib'
  $ ls -la /tmp/build/perf/*.so.*
  lrwxrwxrwx. 1 acme acme    16 Jul 22 15:37 /tmp/build/perf/libperf.so.0 -> libperf.so.0.0.1
  -rwxrwxr-x. 1 acme acme 16368 Jul 22 15:37 /tmp/build/perf/libperf.so.0.0.1

Subject: libperf: Add perf_cpu_map struct

Add perf_cpu_map struct to libperf.

It's added as a declaration into:

  include/perf/cpumap.h

which will be included by users.

The perf_cpu_map struct definition is added into:

  include/internal/cpumap.h

which is not to be included by users, but shared within perf and
libperf.

We tried the total separation of the perf_cpu_map struct in libperf, but
it lead to complications and much bigger changes in perf code, so we
decided to share the declaration.

From 07acd22677ac6bb2db404d1d258e8c7d06ca7706 Mon Sep 17 00:00:00 2001
From: Jiri Olsa <jolsa@kernel.org>
Date: Sun, 21 Jul 2019 13:24:18 +0200
Subject: libperf: Add perf_thread_map struct

Add perf_thread_map struct to libperf.

It's added as a declaration into into:

  include/perf/threadmap.h

which will be included by users.

The perf_thread_map struct definition is added into:

  include/internal/threadmap.h

which is not to be included by users, but shared within perf and
libperf.

We tried the total separation of the perf_thread_map struct in libperf,
but it lead to complications and much bigger changes in perf code, so we
decided to share the declaration.

Subject: libperf: Add perf_thread_map__new_dummy() function

Moving the following functions:

  thread_map__new_dummy()
  thread_map__realloc()
  thread_map__set_pid()

to libperf with the following names:

  perf_thread_map__new_dummy()
  perf_thread_map__realloc()
  perf_thread_map__set_pid()

the other 2 functions are dependencies of the
perf_thread_map__new_dummy() function.

The perf_thread_map__realloc() function is not exported.

Subject: libperf: Add perf_evlist and perf_evsel structs

Add the perf_evlist and perf_evsel structs to libperf.

It's added as a declarations into:

  include/perf/evlist.h
  include/perf/evsel.h

which will be included by users.

The definitions are added into:

  include/internal/evlist.h
  include/internal/evsel.h

which is not to be included by users, but shared
within perf and libperf.

So move the initialization of the core evlist (calling
perf_evlist__init()) to before perf_evlist__set_maps() in
evlist__init().

Subject: libperf: Move perf_event_attr field from perf's evsel to libperf's
 perf_evsel

Move the perf_event_attr struct fron 'struct evsel' to 'struct perf_evsel'.

Committer notes:

Fixed up these:

 tools/perf/arch/arm/util/auxtrace.c
 tools/perf/arch/arm/util/cs-etm.c
 tools/perf/arch/arm64/util/arm-spe.c
 tools/perf/arch/s390/util/auxtrace.c
 tools/perf/util/cs-etm.c

Also

  cc1: warnings being treated as errors
  tests/sample-parsing.c: In function 'do_test':
  tests/sample-parsing.c:162: error: missing initializer
  tests/sample-parsing.c:162: error: (near initialization for 'evsel.core.cpus')

   	struct evsel evsel = {
   		.needs_swap = false,
  -		.core.attr = {
  -			.sample_type = sample_type,
  -			.read_format = read_format,
  +		.core = {
  +			. attr = {
  +				.sample_type = sample_type,
  +				.read_format = read_format,
  +			},

  [perfbuilder@a70e4eeb5549 /]$ gcc --version |& head -1
  gcc (GCC) 4.4.7

Also we don't need to include perf_event.h in
tools/perf/lib/include/perf/evsel.h, forward declaring 'struct
perf_event_attr' is enough. And this even fixes the build in some
systems where things are used somewhere down the include path from
perf_event.h without defining __always_inline.

Subject: libperf: Add perf_evlist__for_each_evsel() iterator

Add a perf_evlist__for_each_evsel() macro to iterate perf_evsel objects
in evlist.

Introduce the perf_evlist__next() function to do that without exposing
'struct perf_evlist' internals.

From 453fa03090a64c0e0a561f10dfd5e8747796949c Mon Sep 17 00:00:00 2001
From: Jiri Olsa <jolsa@kernel.org>
Date: Sun, 21 Jul 2019 13:24:43 +0200
Subject: libperf: Add perf_evlist__set_maps() function

Move the evlist__set_maps() function from tools/perf to libperf.

Committer notes:

Fix up reject due to earlier inversion in calling perf_evlist__init().

Subject: libperf: Adopt the readn()/writen() functions from tools/perf

Move the readn()/writen() functions into libperf.

Keep those non-namespaced names because they will be shared only between
perf and libperf.

Again, these are not exported functions.

Subject: libperf: Adopt simplified perf_evsel__open() function from tools/perf

Add a perf_evsel__open() function to libperf.

It's a simplified version of evsel__open() without the fallback
mechanism.

We can try to merge it in the future to libperf, but it has many
details, lets start simple, requiring the latest kernel, perf should
continue using its evsel__open() version, continuing to support running
on older kernels when possible.

Date: Sun, 21 Jul 2019 13:24:52 +0200
Subject: libperf: Adopt perf_evsel__enable()/disable()/apply_filter()
 functions

Move the following functions:

  evsel__enable()
  evsel__disable()
  evsel__apply_filter()

to libperf with the following names:

  perf_evsel__enable()
  perf_evsel__disable()
  perf_evsel__apply_filter()

Export only perf_evsel__enable()/disable(), keeping the
perf_evsel__apply_filter() one private for the moment.

Subject: libperf: Add perf_cpu_map__for_each_cpu() macro

Add the following macro to libperf:

  perf_cpu_map__for_each_cpu()

And its related functions:

  perf_cpu_map__cpu()
  perf_cpu_map__nr()

That will allow hiding how it is implemented.

Subject: libperf: Adopt simplified perf_evlist__open()/close() functions from
 tools/perf

Add the following functions:

  perf_evlist__open()
  perf_evlist__close()

It's a simplified version of perf's evlist__open() without the sampling
id index calculations. We can try to merge it in the future when we need
it in some new libperf user.

Also adopt some helper evlist traversing macros. In the future we can
remove them from util/evlist.h, but that requires also some other
changes.

    INSTALL  libperf.a
    INSTALL  libperf.so
    INSTALL  libperf.so.0
    INSTALL  libperf.so.0.0.1
    INSTALL  headers
    INSTALL  libperf.pc

  $ find /tmp/krava/

+libperf tutorial
+================
+
+Compile and install libperf from kernel sources
+===============================================
+.. code-block:: bash
+
+  git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
+  cd linux/tools/perf/lib
+  make
+  sudo make install prefix=/usr
+
+Libperf object
+==============
+The libperf library provides several high level objects:
+
+struct perf_cpu_map
+  Provides a cpu list abstraction.
+
+struct perf_thread_map
+  Provides a thread list abstraction.
+
+struct perf_evsel
+  Provides an abstraction for single a perf event.
+
+struct perf_evlist
+  Gathers several struct perf_evsel object and performs functions on all of them.
+
+The exported API binds these objects together,
+for full reference see the libperf.7 man page.
+
+Examples
+========
+Examples aim to explain libperf functionality on simple use cases.
+They are based in on a checked out linux kernel git tree:
+
+.. code-block:: bash
+
+  $ cd tools/perf/lib/Documentation/tutorial/
+  $ ls -d  ex-*
+  ex-1-compile  ex-2-evsel-stat  ex-3-evlist-stat
+
+ex-1-compile example
+====================
+This example shows the basic usage of *struct perf_cpu_map*,
+how to create it and display its cpus:
+
+.. code-block:: bash
+
+  $ cd ex-1-compile/
+  $ make
+  gcc -o test test.c -lperf
+  $ ./test
+  0 1 2 3 4 5 6 7
+
+
+The full code listing is here:
+
+.. code-block:: c
+
+   1 #include <perf/cpumap.h>
+   2
+   3 int main(int argc, char **Argv)
+   4 {
+   5         struct perf_cpu_map *cpus;
+   6         int cpu, tmp;
+   7
+   8         cpus = perf_cpu_map__new(NULL);
+   9
+  10         perf_cpu_map__for_each_cpu(cpu, tmp, cpus)
+  11                 fprintf(stdout, "%d ", cpu);
+  12
+  13         fprintf(stdout, "\n");
+  14
+  15         perf_cpu_map__put(cpus);
+  16         return 0;
+  17 }
+
+
+First you need to include the proper header to have *struct perf_cpumap*
+declaration and functions:
+
+.. code-block:: c
+
+   1 #include <perf/cpumap.h>
+
+
+The *struct perf_cpumap* object is created by *perf_cpu_map__new* call.
+The *NULL* argument asks it to populate the object with the current online CPUs list:
+
+.. code-block:: c
+
+   8         cpus = perf_cpu_map__new(NULL);
+
+This is paired with a *perf_cpu_map__put*, that drops its reference at the end, possibly deleting it.
+
+.. code-block:: c
+
+  15         perf_cpu_map__put(cpus);
+
+The iteration through the *struct perf_cpumap* CPUs is done using the *perf_cpu_map__for_each_cpu*
+macro which requires 3 arguments:
+
+- cpu  - the cpu numer
+- tmp  - iteration helper variable
+- cpus - the *struct perf_cpumap* object
+
+.. code-block:: c
+
+  10         perf_cpu_map__for_each_cpu(cpu, tmp, cpus)
+  11                 fprintf(stdout, "%d ", cpu);
+
+ex-2-evsel-stat example
+=======================
+
+TBD
+
+ex-3-evlist-stat example
+========================
+
+TBD

Subject: selftests/bpf: add test for bpf_tcp_gen_syncookie

Modify the existing bpf_tcp_check_syncookie test to also generate a
SYN cookie, pass the packet to the kernel, and verify that the two
cookies are the same (and both valid). Since cloned SKBs are skipped
during generic XDP, this test does not issue a SYN cookie when run in
XDP mode. We therefore only check that a valid SYN cookie was issued at
the TC hook.

Additionally, verify that the MSS for that SYN cookie is within
expected range.

Subject: selftests/bpf: fix clearing buffered output between tests/subtests

Clear buffered output once test or subtests finishes even if test was
successful. Not doing this leads to accumulation of output from previous
tests and on first failed tests lots of irrelevant output will be
dumped, greatly confusing things.

v1->v2: fix Fixes tag, add more context to patch

Subject: tools: bpftool: add support for reporting the effective cgroup progs

Takshak said in the original submission:

With different bpf attach_flags available to attach bpf programs specially
with BPF_F_ALLOW_OVERRIDE and BPF_F_ALLOW_MULTI, the list of effective
bpf-programs available to any sub-cgroups really needs to be available for
easy debugging.

Using BPF_F_QUERY_EFFECTIVE flag, one can get the list of not only attached
bpf-programs to a cgroup but also the inherited ones from parent cgroup.

So a new option is introduced to use BPF_F_QUERY_EFFECTIVE query flag here
to list all the effective bpf-programs available for execution at a specified
cgroup.

Reused modified test program test_cgroup_attach from tools/testing/selftests/bpf:
  # ./test_cgroup_attach

With old bpftool:

 # bpftool cgroup show /sys/fs/cgroup/cgroup-test-work-dir/cg1/
  ID       AttachType      AttachFlags     Name
  271      egress          multi           pkt_cntr_1
  272      egress          multi           pkt_cntr_2

Attached new program pkt_cntr_4 in cg2 gives following:

 # bpftool cgroup show /sys/fs/cgroup/cgroup-test-work-dir/cg1/cg2
  ID       AttachType      AttachFlags     Name
  273      egress          override        pkt_cntr_4

And with new "effective" option it shows all effective programs for cg2:

 # bpftool cgroup show /sys/fs/cgroup/cgroup-test-work-dir/cg1/cg2 effective
  ID       AttachType      AttachFlags     Name
  273      egress          override        pkt_cntr_4
  271      egress          override        pkt_cntr_1
  272      egress          override        pkt_cntr_2

Compared to original submission use a local flag instead of global
option.

We need to clear query_flags on every command, in case batch mode
wants to use varying settings.

v2: (Takshak)
 - forbid duplicated flags;
 - fix cgroup path freeing.

These two tests have some problems in the global scope pollution and on
contrary, contain unnecessary local declarations. Fix them.

Subject: selftests: mlxsw: Add a test for leftover DSCP rule

Commit dedfde2fe1c4 ("mlxsw: spectrum_dcb: Configure DSCP map as the last
rule is removed") fixed a problem in mlxsw where last DSCP rule to be
removed remained in effect when DSCP rewrite was applied.

Add a selftest that covers this problem.

Subject: tc-testing: Clarify the use of tdc's -d option

The -d command line argument to tdc requires the name of a physical device
on the system where the tests will be run. If -d has not been used, tdc
will skip tests that require a physical device.

This patch is intended to better document what the -d option does and how
it is used.

Subject: libbpf : make libbpf_num_possible_cpus function thread safe

Having static variable `cpus` in libbpf_num_possible_cpus function
without guarding it with mutex makes this function thread-unsafe.

If multiple threads accessing this function, in the current form; it
leads to incrementing the static variable value `cpus` in the multiple
of total available CPUs.

Used local stack variable to calculate the number of possible CPUs and
then updated the static variable using WRITE_ONCE().

Changes since v1:
 * added stack variable to calculate cpus
 * serialized static variable update using WRITE_ONCE()
 * fixed Fixes tag

Subject: libbpf: set BTF FD for prog only when there is supported .BTF.ext
 data

5d01ab7bac46 ("libbpf: fix erroneous multi-closing of BTF FD")
introduced backwards-compatibility issue, manifesting itself as -E2BIG
error returned on program load due to unknown non-zero btf_fd attribute
value for BPF_PROG_LOAD sys_bpf() sub-command.

This patch fixes bug by ensuring that we only ever associate BTF FD with
program if there is a BTF.ext data that was successfully loaded into
kernel, which automatically means kernel supports func_info/line_info
and associated BTF FD for progs (checked and ensured also by BTF
sanitization code).

Subject: selftests/bpf: tests for jmp to 1st insn

Add 2 tests that check JIT code generation to jumps to 1st insn.
1st test is similar to syzbot reproducer.
The backwards branch is never taken at runtime.
2nd test has branch to 1st insn that executes.
The test is written as two bpf functions, since it's not possible
to construct valid single bpf program that jumps to 1st insn.

Subject: torture: Expand last_ts variable in kvm-test-1-run.sh

The kvm-test-1-run.sh script says 'test -z "last_ts"' which always
evaluates to true (AKA zero) regardless of the value of the last_ts shell
variable.  This commit therefore inserts the needed dollar sign ("$").

Subject: rcutorture: Test TREE03 with the threadirqs kernel boot parameter

Since commit 05f415715ce45 ("rcu: Speed up expedited GPs when interrupting
RCU reader") in v5.0 and through v5.1, booting with the threadirqs kernel
boot parameter caused self-deadlocks, which can be reproduced using the
following command on an 8-CPU system:

tools/testing/selftests/rcutorture/bin/kvm.sh --duration 5 --configs "TREE03" --bootargs "threadirqs"

This commit therefore adds the threadirqs kernel boot parameter to
the TREE03 rcutorture scenario in order to more quickly detect future
similar bugs.

Subject: KVM: selftests: Split ucall.c into architecture specific files

The way we exit from a guest to userspace is very specific to the
architecture: On x86, we use PIO, on aarch64 we are using MMIO and on
s390x we're going to use an instruction instead. The possibility to
select a type via the ucall_type_t enum is currently also completely
unused, so the code in ucall.c currently looks more complex than
required. Let's split this up into architecture specific ucall.c
files instead, so we can get rid of the #ifdefs and the unnecessary
ucall_type_t handling.

Subject: KVM: selftests: Implement ucall() for s390x

On s390x, we can neither exit via PIO nor MMIO, but have to use an
instruction like DIAGNOSE. Now that ucall() is implemented, we can
use it in the sync_reg_test on s390x, too.

Subject: KVM: selftests: Enable dirty_log_test on s390x

To run the dirty_log_test on s390x, we have to make sure that we
access the dirty log bitmap with little endian byte ordering and
we have to properly align the memslot of the guest.
Also all dirty bits of a segment are set once on s390x when one
of the pages of a segment are written to for the first time, so
we have to make sure that we touch all pages during the first
iteration to keep the test in sync here.
DEFAULT_GUEST_TEST_MEM needs an adjustment, too. On some s390x
distributions, the ELF binary is linked to address 0x80000000,
so we have to avoid that our test region overlaps into this area.
0xc0000000 seems to be a good alternative that should work on x86
and aarch64, too.

Subject: selftests: Add nettest

Add nettest - a simple program with an implementation for various networking
APIs. nettest is used for tcp, udp and raw functional tests for both IPv4
and IPv6.

Point of this command versus existing utilities:
- controlled implementation of the APIs and the order in which they
  are called,
- ability to verify ingress device, local and remote addresses,
- timeout for controlled test length,
- ability to discriminate a timeout from a system call failure, and
- simplicity with test scripts.

The command returns:
  0  on success,
  1  for any system call failure, and
  2  on timeout.

From c032dd8cc7e23bbcc53e00b262594657ff1b7532 Mon Sep 17 00:00:00 2001
From: David Ahern <dsahern@gmail.com>

Subject: selftests: Add ipv4 ping tests to fcnal-test

Add ping tests to fcnal-test.sh. Covers the permutations of directly
connected addresses, routed destinations, VRF and non-VRF, and expected
failures.

Setup includes unreachable routes and fib rules blocking traffic.

Subject: selftests: Add ipv4 tcp tests to fcnal-test

Add tcp tests to fcnal-test.sh. Covers the permutations of directly
connected addresses, routed destinations, VRF and non-VRF, and expected
failures for both clients and servers. Includes permutations with
net.ipv4.tcp_l3mdev_accept set to 0 and 1.

Subject: selftests: Add ipv6 tcp tests to fcnal-test

Add IPv6 tcp tests to fcnal-test.sh. Covers the permutations of directly
connected addresses, routed destinations, VRF and non-VRF, and expected
failures for both clients and servers. Includes permutations with
net.ipv4.tcp_l3mdev_accept set to 0 and 1.

Subject: selftests: Add ipv4 udp tests to fcnal-test

Add udp tests to fcnal-test.sh. Covers the permutations of directly
connected addresses, routed destinations, VRF and non-VRF, and expected
failures for both clients and servers. Includes permutations with
net.ipv4.udp_l3mdev_accept set to 0 and 1.

Add use case section to fcnal-test.

Initial test is VRF based with a bridge and vlans. The commands
stem from bug reports fixed by:

a173f066c7cf ("netfilter: bridge: Don't sabotage nf_hook calls from an l3mdev")
cd6428988bf4 ("netfilter: bridge: Don't sabotage nf_hook calls for an l3mdev slave")

Subject: selftests: netfilter: extend flowtable test script for ipsec

'flow offload' expression should not offload flows that will be subject
to ipsec, but it does.

This results in a connectivity blackhole for the affected flows -- first
packets will go through (offload happens after established state is
reached), but all remaining ones bypass ipsec encryption and are thus
discarded by the peer.

This can be worked around by adding "rt ipsec exists accept"
before the 'flow offload' rule matches.

This test case will fail, support for such flows is added in
next patch.

Add a test with multiple exit conditions.
It's not an infinite loop only when the verifier can properly track
all math on variable 'i' through all possible ways of executing this loop.

barrier()s are needed to disable llvm optimization that combines multiple
branches into fewer branches.

Subject: selftests, arm64: add a selftest for passing tagged pointers to
 kernel

This patch is a part of a series that extends kernel ABI to allow to pass
tagged user pointers (with the top byte set to something else other than
0x00) as syscall arguments.

This patch adds a simple test, that calls the uname syscall with a
tagged user pointer as an argument. Without the kernel accepting tagged
user pointers the test fails with EFAULT.

Subject: pidfd: add pidfd_wait tests

Add tests for pidfd_wait() and CLONE_WAIT_PID:
- test that waitid(P_PIDFD) fails on /proc/<pid>
- test that waitid(P_PIDFD) fails on /dev/null
- test that waitid(P_PIDFD) can wait on a pidfd
- test that waitid(P_PIDFD) can wait on a pidfd and return siginfo_t
- test that waitid(P_PIDFD) works with WEXITED
- test that waitid(P_PIDFD) works with WSTOPPED
- test that waitid(P_PIDFD) works with WUNTRACED
- test that waitid(P_PIDFD) works with WCONTINUED
- test that waitid(P_PIDFD) works with WNOWAIT
- test that waitid(P_PIDFD)works with WNOHANG

Subject: tests: add pidfd poll tests

This adds testing for polling on pidfd of a process being killed. Test runs
10000 iterations by default to stress test pidfd polling functionality.
It accepts an optional command-line parameter to override the number or
iterations to run.
Specifically, it tests for:
- pidfd_open on a child process succeeds
- pidfd_send_signal on a child process succeeds
- polling on pidfd succeeds and returns exactly one event
- returned event is POLLIN
- event is received within 3 secs of the process being killed

10000 iterations was chosen because of the race condition being tested
which is not consistently reproducible but usually is revealed after less
than 2000 iterations.
Reveals race fixed by commit b191d6491be6 ("pidfd: fix a poll race when setting exit_state")

From 946152b3c5d6bab128db8eee226ec2665429b79c Mon Sep 17 00:00:00 2001
From: Stanislav Fomichev <sdf@google.com>
Date: Tue, 6 Aug 2019 10:45:27 -0700
Subject: selftests/bpf: test_progs: switch to open_memstream

Use open_memstream to override stdout during test execution.
The copy of the original stdout is held in env.stdout and used
to print subtest info and dump failed log.

test_{v,}printf are now simple wrappers around stdout and will be
removed in the next patch.

v5:
* fix -v crash by always setting env.std{in,err} (Alexei Starovoitov)
* drop force_log check from stdio_hijack (Andrii Nakryiko)

v4:
* one field per line for stdout/stderr (Andrii Nakryiko)

v3:
* don't do strlen over log_buf, log_cnt has it already (Andrii Nakryiko)

v2:
* add ifdef __GLIBC__ around open_memstream (maybe pointless since
  we already depend on glibc for argp_parse)
* hijack stderr as well (Andrii Nakryiko)
* don't hijack for every test, do it once (Andrii Nakryiko)
* log_cap -> log_size (Andrii Nakryiko)
* do fseeko in a proper place (Andrii Nakryiko)
* check open_memstream returned value (Andrii Nakryiko)

From 4cedc0dad9b5bf55c4180c833be35e27e5d6cdbb Mon Sep 17 00:00:00 2001
From: Andrii Nakryiko <andriin@fb.com>
Date: Wed, 7 Aug 2019 14:39:50 -0700
Subject: libbpf: add .BTF.ext offset relocation section loading

Add support for BPF CO-RE offset relocations. Add section/record
iteration macros for .BTF.ext. These macro are useful for iterating over
each .BTF.ext record, either for dumping out contents or later for BPF
CO-RE relocation handling.

To enable other parts of libbpf to work with .BTF.ext contents, moved
a bunch of type definitions into libbpf_internal.h.

Subject: libbpf: implement BPF CO-RE offset relocation algorithm

This patch implements the core logic for BPF CO-RE offsets relocations.
Every instruction that needs to be relocated has corresponding
bpf_offset_reloc as part of BTF.ext. Relocations are performed by trying
to match recorded "local" relocation spec against potentially many
compatible "target" types, creating corresponding spec. Details of the
algorithm are noted in corresponding comments in the code.

+ * CO-RE relocate single instruction.
+ *
+ * The outline and important points of the algorithm:
+ * 1. For given local type, find corresponding candidate target types.
+ *    Candidate type is a type with the same "essential" name, ignoring
+ *    everything after last triple underscore (___). E.g., `sample`,
+ *    `sample___flavor_one`, `sample___flavor_another_one`, are all candidates
+ *    for each other. Names with triple underscore are referred to as
+ *    "flavors" and are useful, among other things, to allow to
+ *    specify/support incompatible variations of the same kernel struct, which
+ *    might differ between different kernel versions and/or build
+ *    configurations.
+ *
+ *    N.B. Struct "flavors" could be generated by bpftool's BTF-to-C
+ *    converter, when deduplicated BTF of a kernel still contains more than
+ *    one different types with the same name. In that case, ___2, ___3, etc
+ *    are appended starting from second name conflict. But start flavors are
+ *    also useful to be defined "locally", in BPF program, to extract same
+ *    data from incompatible changes between different kernel
+ *    versions/configurations. For instance, to handle field renames between
+ *    kernel versions, one can use two flavors of the struct name with the
+ *    same common name and use conditional relocations to extract that field,
+ *    depending on target kernel version.
+ * 2. For each candidate type, try to match local specification to this
+ *    candidate target type. Matching involves finding corresponding
+ *    high-level spec accessors, meaning that all named fields should match,
+ *    as well as all array accesses should be within the actual bounds. Also,
+ *    types should be compatible (see bpf_core_fields_are_compat for details).
+ * 3. It is supported and expected that there might be multiple flavors
+ *    matching the spec. As long as all the specs resolve to the same set of
+ *    offsets across all candidates, there is not error. If there is any
+ *    ambiguity, CO-RE relocation will fail. This is necessary to accomodate
+ *    imprefection of BTF deduplication, which can cause slight duplication of
+ *    the same BTF type, if some directly or indirectly referenced (by
+ *    pointer) type gets resolved to different actual types in different
+ *    object files. If such situation occurs, deduplicated BTF will end up
+ *    with two (or more) structurally identical types, which differ only in
+ *    types they refer to through pointer. This should be OK in most cases and
+ *    is not an error.
+ * 4. Candidate types search is performed by linearly scanning through all
+ *    types in target BTF. It is anticipated that this is overall more
+ *    efficient memory-wise and not significantly worse (if not better)
+ *    CPU-wise compared to prebuilding a map from all local type names to
+ *    a list of candidate type names. It's also sped up by caching resolved
+ *    list of matching candidates per each local "root" type ID, that has at
+ *    least one bpf_offset_reloc associated with it. This list is shared
+ *    between multiple relocations for the same type ID and is updated as some
+ *    of the candidates are pruned due to structural incompatibility.

Subject: selftests/bpf: add CO-RE relocs testing setup

Add CO-RE relocation test runner. Add one simple test validating that
libbpf's logic for searching for kernel image and loading BTF out of it
works.

Subject: selftests/bpf: add CO-RE relocs ptr-as-array tests

Add test validating correct relocation handling for cases where pointer
to something is used as an array. E.g.:

  int *ptr = ...;
  int x = ptr[42];

Subject: tools/bpf: fix core_reloc.c compilation error
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On my local machine, I have the following compilation errors:
=====
  In file included from prog_tests/core_reloc.c:3:0:
  ./progs/core_reloc_types.h:517:46: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘fancy_char_ptr_t’
 typedef const char * const volatile restrict fancy_char_ptr_t;
                                              ^
  ./progs/core_reloc_types.h:527:2: error: unknown type name ‘fancy_char_ptr_t’
    fancy_char_ptr_t d;
    ^
=====

I am using gcc 4.8.5. Later compilers may change their behavior not emitting the
error. Nevertheless, let us fix the issue. "restrict" can be tested
without typedef.

Fixes: 9654e2ae908e ("selftests/bpf: add CO-RE relocs modifiers/typedef tests")

Subject: tools/memory-model: Use cumul-fence instead of fence in ->prop
 example

To reduce ambiguity in the more exotic ->prop ordering example, this
commit uses the term cumul-fence instead of the term fence for the two
fences, so that the implict ->rfe on loads/stores to Y are covered by
the description.

Subject: tools/memory-model: Update the informal documentation

The formal memory consistency model has added support for plain accesses
(and data races).  While updating the informal documentation to describe
this addition to the model is highly desirable and important future work,
update the informal documentation to at least acknowledge such addition.

Subject: selftests: Fix detection of nettest command in fcnal-test

Most of the tests run by fcnal-test.sh relies on the nettest command.
Rather than trying to cover all of the individual tests, check for the
binary only at the beginning.

Also removes the need for log_error which is undefined.

Subject: tools: bpftool: fix reading from /proc/config.gz

/proc/config has never existed as far as I can see, but /proc/config.gz
is present on Arch Linux. Add support for decompressing config.gz using
zlib which is a mandatory dependency of libelf anyway. Replace existing
stdio functions with gzFile operations since the latter transparently
handles uncompressed and gzip-compressed files.

Subject: perf session: Avoid infinite loop when seeing invalid header.size

Vince reported that when fuzzing the userland perf tool with a bogus
perf.data file he got into a infinite loop in 'perf report'.

Changing the return of fetch_mmaped_event() to ERR_PTR(-EINVAL) for that
case gets us out of that infinite loop.

Subject: perf config: Honour $PERF_CONFIG env var to specify alternate
 .perfconfig
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We had this comment in Documentation/perf_counter/config.c, i.e. since
when we got this from the git sources, but never really did that
getenv("PERF_CONFIG"), do it now as I need to disable whatever
~/.perfconfig root has so that tests parsing tool output are done for
the expected default output or that we specify an alternate config file
that when read will make the tools produce expected output.

Subject: perf config: Document the PERF_CONFIG environment variable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There was a provision for setting this variable, but not the
getenv("PERF_CONFIG") call to set it, as this was fixed in the previous
cset, document that it can be used to ask for using an alternative
.perfconfig file or to disable reading whatever file exists in the
system or home directory, i.e. using:

  export PERF_CONFIG=/dev/null

Subject: perf test vfs_getname: Disable ~/.perfconfig to get default output
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

To get the expected output we have to ignore whatever changes the user
has in its ~/.perfconfig file, so set PERF_CONFIG to /dev/null to
achieve that.

Before:

  # egrep 'trace|show_' ~/.perfconfig
  [trace]
  	show_zeros = yes
  	show_duration = no
  	show_timestamp = no
  	show_arg_names = no
  	show_prefix = yes
  # echo $PERF_CONFIG

  # perf test "trace + vfs_getname"
  70: Check open filename arg using perf trace + vfs_getname: FAILED!
  # export PERF_CONFIG=/dev/null
  # perf test "trace + vfs_getname"
  70: Check open filename arg using perf trace + vfs_getname: Ok
  #

After:

  # egrep 'trace|show_' ~/.perfconfig
  [trace]
  	show_zeros = yes
  	show_duration = no
  	show_timestamp = no
  	show_arg_names = no
  	show_prefix = yes
  # echo $PERF_CONFIG

  # perf test "trace + vfs_getname"
  70: Check open filename arg using perf trace + vfs_getname: Ok

These paths point to the wrong location but still work because they get
picked up by a -I flag that happens to direct to the correct file. Fix
paths to lead to the actual file location without help from include
flags.

Subject: perf hists: Do not link a pair if already linked

When we have multiple events in a group we link hist_entries in the
non-leader evsel hists to the one in the leader that points to the same
sorting criteria, in hists__match().

For 'perf report' we do this just once and then print the results, but
for 'perf top' we need to look if this was already done in the previous
refresh of the screen, so check for that and don't try to link again.

This is part of having 'perf top' using the hists browser for showing
multiple events in multiple columns.

  Segmentation fault

This issue is introduced by commit 30a910d7d3e0 ("perf trace:
Preallocate the syscall table"), it allocates trace->syscalls.table[]
array and the element count is 'trace->sctbl->syscalls.nr_entries'; but
on Arm64, the system call number is not continuously used; e.g. the
syscall maximum id is 436 but the real entries is only 281.

So the table is allocated with 'nr_entries' as the element count, but it
accesses the table with the syscall id, which might be out of the bound
of the array and cause the segmentation fault.

This patch allocates trace->syscalls.table[] with the element count is
'trace->sctbl->syscalls.max_id + 1', this allows any id to access the
table without out of the bound.

Subject: perf hist: Remove dummy entries when finding real ones.

When he have an event group we have multiple struct hist instances, one
per evsel, and in each of these hists we may have hist_entries that
point to the same thing being observed, say a symbol, i.e. if we're
looking at instructions and cycles, then we'll have one hist_entry in
the "instructions" evsel and another in the "cycles" evsel.

We need to link those to then show one column for each. When we're
looking at some other pair of events, say instructions and cache misses,
we may have just the "instructions" hist entry and not one for "cache
misses", as instructions not necessarily generate cache misses, as the
logic expects one hist_entry per evsel, we end up adding "dummy"
hist_entries.

This is enough for 'perf report', that does this matching operation
(hists__match()) just once after processing all events, but for 'perf
top', we do this at each refresh, so we may finally find events matching
and then we need to trow away the dummies and link with the real events.

So if we find a match, traverse the link of matches and trow away
dummies for that hists.

Subject: perf top: Collapse and resort all evsels in a group

And link them, i.e. find the hist entries in the non-leader events and
link them to the ones in the leader.

This should be the same thing already done for the 'perf report' case,
but now we do it periodically.

With this in place we get percentages in from the second overhead column
on, not just on the first (the leader).

Try it using:

  perf top --stdio -e '{cycles,instructions}'

You should see something like:

Subject: tools build: Add capability-related feature detection

Add utilities to help checking capabilities of the running procss.  Make
perf link with libcap, if it is available. If no libcap-dev[el], assume
no capabilities.

Committer testing:

  $ make O=/tmp/build/perf -C tools/perf install-bin
  make: Entering directory '/home/acme/git/perf/tools/perf'
    BUILD:   Doing 'make -j8' parallel build

  Auto-detecting system features:
  <SNIP>
  ...                        libbfd: [ on  ]
  ...                        libcap: [ OFF ]
  ...                        libelf: [ on  ]
  <SNIP>
  Makefile.config:833: No libcap found, disables capability support, please install libcap-devel/libcap-dev
  <SNIP>
  $ grep libcap /tmp/build/perf/FEATURE-DUMP

  $ cat /tmp/build/perf/feature/test-libcap.make.output

      2 | #include <sys/capability.h>
        |          ^~~~~~~~~~~~~~~~~~
  compilation terminated.
  $

Now install libcap-devel and try again:

  $ make O=/tmp/build/perf -C tools/perf install-bin
  make: Entering directory '/home/acme/git/perf/tools/perf'

Subject: tools: bpftool: add feature check for zlib

bpftool requires libelf, and zlib for decompressing /proc/config.gz.
zlib is a transitive dependency via libelf, and became mandatory since
elfutils 0.165 (Jan 2016). The feature check of libelf is already done
in the elfdep target of tools/lib/bpf/Makefile, pulled in by bpftool via
a dependency on libbpf.a. Add a similar feature check for zlib.

Subject: selftests/bpf: fix race in flow dissector tests

Since the "last_dissection" map holds only the flow keys for the most
recent packet, there is a small race in the skb-less flow dissector
tests if a new packet comes between transmitting the test packet, and
reading its keys from the map. If this happens, the test packet keys
will be overwritten and the test will fail.

Changing the "last_dissection" map to a hash map, keyed on the
source/dest port pair resolves this issue. Additionally, let's clear the
last test results from the map between tests to prevent previous test
cases from interfering with the following test cases.

Fixes: 0905beec9f52 ("selftests/bpf: run flow dissector tests in skb-less mode")

Subject: libbpf: attempt to load kernel BTF from sysfs first

Add support for loading kernel BTF from sysfs (/sys/kernel/btf/vmlinux)
as a target BTF. Also extend the list of on disk search paths for
vmlinux ELF image with entries that perf is searching for.

Subject: perf tools: Add helpers to use capabilities if present

Add utilities to help checking capabilities of the running procss.  Make
perf link with libcap, if it is available. If no libcap-dev[el],
fallback to the geteuid() == 0 test used before.

Committer notes:

  $ perf test python
  18: 'import perf' in python                               : FAILED!
  $ perf test -v python
  Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc
  18: 'import perf' in python                               :
  --- start ---
  test child forked, pid 23288
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  ImportError: /tmp/build/perf/python/perf.so: undefined symbol: cap_get_flag
  test child finished with -1
  ---- end ----
  'import perf' in python: FAILED!
  $

This happens because differently from the perf binary generated with
this patch applied:

  $ ldd /tmp/build/perf/perf | grep libcap
  	libcap.so.2 => /lib64/libcap.so.2 (0x00007f724a4ef000)
  $

The python binding isn't linking with libcap:

  $ ldd /tmp/build/perf/python/perf.so | grep libcap
  $

So add 'cap' to the 'extra_libraries' variable in
tools/perf/util/setup.py, and rebuild:

  $ perf test python
  18: 'import perf' in python                               : Ok
  $

If we explicitely disable libcap it also continues to work:

  $ make NO_LIBCAP=1 -C tools/perf O=/tmp/build/perf install-bin
    $ ldd /tmp/build/perf/perf | grep libcap
  $ ldd /tmp/build/perf/python/perf.so | grep libcap
  $ perf test python
  18: 'import perf' in python                               : Ok
  $

Subject: perf record: Add an option to take an AUX snapshot on exit

It is sometimes useful to generate a snapshot when perf record exits;
I've been using a wrapper script around the workload that would do a
killall -USR2 perf when the workload exits.

This patch makes it easier and also works when perf record is attached
to a pre-existing task. A new snapshot option 'e' can be specified in
-S to enable this behavior:

root@elsewhere:~# perf record -e intel_pt// -Se sleep 1
[ perf record: Woken up 2 times to write data ]
[ perf record: Captured and wrote 0.085 MB perf.data ]

Subject: perf tools: Add aux-output config term

Expose the aux_output attribute flag to the user to configure, by adding a
config term 'aux-output'. For events that support it, selection of
'aux-output' causes the generation of AUX records instead of event records.
This requires that an AUX area event is also provided.

+PEBS via Intel PT
+=================
+
+Some hardware has the feature to redirect PEBS records to the Intel PT trace.
+Recording is selected by using the aux-output config term e.g.
+
+	perf record -c 10000 -e '{intel_pt/branch=0/,cycles/aux-output/ppp}' uname
+
+Note that currently, software only supports redirecting at most one PEBS event.
+
+To display PEBS events from the Intel PT trace, use the itrace 'o' option e.g.
+
+	perf script --itrace=oe

  Error:
  The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (cycles/aux-output/ppp).
  /bin/dmesg | grep -i perf may provide additional information.

After:

  # perf record -e {intel_pt/branch=0/,cycles/aux-output/ppp} uname
  Error:
  The 'aux_output' feature is not supported, update the kernel.

Subject: selftests/bpf: fix "bind{4, 6} deny specific IP & port" on s390

"bind4 allow specific IP & port" and "bind6 deny specific IP & port"
fail on s390 because of endianness issue: the 4 IP address bytes are
loaded as a word and compared with a constant, but the value of this
constant should be different on big- and little- endian machines, which
is not the case right now.

Use __bpf_constant_ntohl to generate proper value based on machine
endianness.

Subject: tools: bpftool: compile with $(EXTRA_WARNINGS)

Compile bpftool with $(EXTRA_WARNINGS), as defined in
scripts/Makefile.include, and fix the new warnings produced.

Simply leave -Wswitch-enum out of the warning list, as we have several
switch-case structures where it is not desirable to process all values
of an enum.

Remove -Wshadow from the warnings we manually add to CFLAGS, as it is
handled in $(EXTRA_WARNINGS).

vmx_set_nested_state_test is trying to use the KVM_STATE_NESTED_EVMCS without
enabling enlightened VMCS first.  Correct the outcome of the test, and actually
test that it succeeds after the capability is enabled.

Subject: perf script: Allow specifying event to switch on processing of other
 events

Sometime we want to only consider events after something happens, so
allow discarding events till such events is found, e.g.:

Record all scheduler tracepoints and the sys_enter_nanosleep syscall
event for the 'sleep 1' workload:

  # perf record -e sched:*,syscalls:sys_enter_nanosleep sleep 1
  [ perf record: Woken up 31 times to write data ]
  [ perf record: Captured and wrote 0.032 MB perf.data (10 samples) ]
  #

So we have these events in the generated perf data file:

  # perf evlist
  sched:sched_kthread_stop
  sched:sched_kthread_stop_ret
  sched:sched_waking
  sched:sched_wakeup
  sched:sched_wakeup_new
  sched:sched_switch
  sched:sched_migrate_task
  sched:sched_process_free
  sched:sched_process_exit
  sched:sched_wait_task
  sched:sched_process_wait
  sched:sched_process_fork
  sched:sched_process_exec
  sched:sched_stat_wait
  sched:sched_stat_sleep
  sched:sched_stat_iowait
  sched:sched_stat_blocked
  sched:sched_stat_runtime
  sched:sched_pi_setprio
  sched:sched_move_numa
  sched:sched_stick_numa
  sched:sched_swap_numa
  sched:sched_wake_idle_without_ipi
  syscalls:sys_enter_nanosleep
  # Tip: use 'perf evlist --trace-fields' to show fields for tracepoint events
  #

Then show all of the events that actually took place in this 'perf record' session:

  # perf script
          :13637 13637 [002] 108237.581529:            sched:sched_waking: comm=perf pid=13638 prio=120 target_cpu=001
          :13637 13637 [002] 108237.581537:            sched:sched_wakeup: perf:13638 [120] success=1 CPU:001
           sleep 13638 [001] 108237.581992:      sched:sched_process_exec: filename=/usr/bin/sleep pid=13638 old_pid=13638

           sleep 13638 [001] 108237.582289:      sched:sched_stat_runtime: comm=sleep pid=13638 runtime=578104 [ns] vruntime=202889459556 [ns]
           sleep 13638 [001] 108237.582291:            sched:sched_switch: sleep:13638 [120] S ==> swapper/1:0 [120]
         swapper     0 [001] 108238.582428:            sched:sched_waking: comm=sleep pid=13638 prio=120 target_cpu=001
         swapper     0 [001] 108238.582458:            sched:sched_wakeup: sleep:13638 [120] success=1 CPU:001
           sleep 13638 [001] 108238.582698:      sched:sched_stat_runtime: comm=sleep pid=13638 runtime=173915 [ns] vruntime=202889633471 [ns]

  #

Now lets see only the ones that took place after a certain "marker":

  # perf script --switch-on syscalls:sys_enter_nanosleep
           sleep 13638 [001] 108237.582289:      sched:sched_stat_runtime: comm=sleep pid=13638 runtime=578104 [ns] vruntime=202889459556 [ns]
           sleep 13638 [001] 108237.582291:            sched:sched_switch: sleep:13638 [120] S ==> swapper/1:0 [120]
         swapper     0 [001] 108238.582428:            sched:sched_waking: comm=sleep pid=13638 prio=120 target_cpu=001
         swapper     0 [001] 108238.582458:            sched:sched_wakeup: sleep:13638 [120] success=1 CPU:001
           sleep 13638 [001] 108238.582698:      sched:sched_stat_runtime: comm=sleep pid=13638 runtime=173915 [ns] vruntime=202889633471 [ns]
           sleep 13638 [001] 108238.582782:      sched:sched_process_exit: comm=sleep pid=13638 prio=120

Subject: perf script: Allow showing the --switch-on event

One may want to see the --switch-on event as well, allow for that, using
the previous cset example:

Subject: perf evswitch: Move struct to a separate header to use in other tools

Now that we see that the simple userspace-based "slicing" of events
using delimiter events ("markers") works, lets move it to a separate
header to make it available to other tools, next step will be having
the switch on/off check done at the PERF_RECORD_SAMPLE processing
function moved too.

Now other tools that want switching can use an evswitch for that, just
set it up and add it to the PERF_RECORD_SAMPLE processing function.

Subject: perf top: Add --switch-on/--switch-off events

Just like 'perf trace' and 'perf script', should be useful for instance
to only consider samples after the initialization phase of some
workload.

The man page has some examples and considerations about its current
interface, that still doesn't handle the on/off events in a special way,
behaving just like when multiple events are specified, i.e.:

- In non-group mode (when the event list is not enclosed in {}) show a
  a menu to allow choosing which event the user wants to see in the
  histograms browser

- In group mode, be it using {} or asking for --group, show one column
  per event.

Try for instance:

  # perf top -e '{cycles,instructions,probe:icmp_rcv}' --switch-on=probe:icmp_rcv

Replace probe:icmp_rcv, that I put in place using:

  # perf probe icmp_rcv:59

To hit when broadcast packets arrive, with a probe installed after an
initialization phase is over or after some other point of interest, some
garbage collection, etc, and also use --switch-off, for instance, on a
probe installed after said garbage collection is over.

Subject: tools: bpftool: add net attach command to attach XDP on interface

By this commit, using `bpftool net attach`, user can attach XDP prog on
interface. New type of enum 'net_attach_type' has been made, as stat ted at
cover-letter, the meaning of 'attach' is, prog will be attached on interface.

With 'overwrite' option at argument, attached XDP program could be replaced.
Added new helper 'net_parse_dev' to parse the network device at argument.

Subject: tools: bpftool: add net detach command to detach XDP on interface

By this commit, using `bpftool net detach`, the attached XDP prog can
be detached. Detaching the BPF prog will be done through libbpf
'bpf_set_link_xdp_fd' with the progfd set to -1.

Subject: libbpf: make libbpf.map source of truth for libbpf version

Currently libbpf version is specified in 2 places: libbpf.map and
Makefile. They easily get out of sync and it's very easy to update one,
but forget to update another one. In addition, Github projection of
libbpf has to maintain its own version which has to be remembered to be
kept in sync manually, which is very error-prone approach.

This patch makes libbpf.map a source of truth for libbpf version and
uses shell invocation to parse out correct full and major libbpf version
to use during build. Now we need to make sure that once new release
cycle starts, we need to add (initially) empty section to libbpf.map
with correct latest version.

This also will make it possible to keep Github projection consistent
with kernel sources version of libbpf by adopting similar parsing of
version from libbpf.map.

v2->v3:
- grep -o + sort -rV (Andrey);

v1->v2:
- eager version vars evaluation (Jakub);
- simplified version regex (Andrey);

Subject: tools: bpftool: fix format strings and arguments for jsonw_printf()

There are some mismatches between format strings and arguments passed to
jsonw_printf() in the BTF dumper for bpftool, which seems harmless but
may result in warnings if the "__printf()" attribute is used correctly
for jsonw_printf(). Let's fix relevant format strings and type cast.

There is one call to the p_err() function in detect_common_prefix()
where the message to print is passed directly as the first argument,
without using a format string. This is harmless, but may trigger
warnings if the "__printf()" attribute is used correctly for the p_err()

Subject: tools: bpftool: move "__printf()" attributes to header file

Some functions in bpftool have a "__printf()" format attributes to tell
the compiler they should expect printf()-like arguments. But because
these attributes are not used for the function prototypes in the header
files, the compiler does not run the checks everywhere the functions are
used, and some mistakes on format string and corresponding arguments
slipped in over time.

Let's move the __printf() attributes to the correct places.

Note: We add guards around the definition of GCC_VERSION in
tools/include/linux/compiler-gcc.h to prevent a conflict in jit_disasm.c
on GCC_VERSION from headers pulled via libbfd.

Subject: tools: bpftool: close prog FD before exit on showing a single program

When showing metadata about a single program by invoking
"bpftool prog show PROG", the file descriptor referring to the program
is not closed before returning from the function. Let's close it.

Subject: perf report: Add --switch-on/--switch-off events

Since 'perf top' shares the histogram browser with 'perf report', then
the same explanation in the previous cset applies.

An additional example uses a pair of SDT events available for systemtap:

  # perf probe --exec=/usr/bin/stap '%*:*'
  Added new events:
    sdt_stap:benchmark__thread__start (on %* in /usr/bin/stap)
    sdt_stap:benchmark   (on %* in /usr/bin/stap)
    sdt_stap:benchmark__thread__end (on %* in /usr/bin/stap)
    sdt_stap:pass6__start (on %* in /usr/bin/stap)
    sdt_stap:pass6__end  (on %* in /usr/bin/stap)
    sdt_stap:pass5__start (on %* in /usr/bin/stap)
    sdt_stap:pass5__end  (on %* in /usr/bin/stap)
    sdt_stap:pass0__start (on %* in /usr/bin/stap)
    sdt_stap:pass0__end  (on %* in /usr/bin/stap)
    sdt_stap:pass1a__start (on %* in /usr/bin/stap)
    sdt_stap:pass1b__start (on %* in /usr/bin/stap)
    sdt_stap:pass1__end  (on %* in /usr/bin/stap)
    sdt_stap:pass2__start (on %* in /usr/bin/stap)
    sdt_stap:pass2__end  (on %* in /usr/bin/stap)
    sdt_stap:pass3__start (on %* in /usr/bin/stap)
    sdt_stap:pass3__end  (on %* in /usr/bin/stap)
    sdt_stap:pass4__start (on %* in /usr/bin/stap)
    sdt_stap:pass4__end  (on %* in /usr/bin/stap)
    sdt_stap:benchmark__start (on %* in /usr/bin/stap)
    sdt_stap:benchmark__end (on %* in /usr/bin/stap)
    sdt_stap:cache__get  (on %* in /usr/bin/stap)
    sdt_stap:cache__clean (on %* in /usr/bin/stap)
    sdt_stap:cache__add__module (on %* in /usr/bin/stap)
    sdt_stap:cache__add__source (on %* in /usr/bin/stap)
    sdt_stap:stap_system__complete (on %* in /usr/bin/stap)
    sdt_stap:stap_system__start (on %* in /usr/bin/stap)
    sdt_stap:stap_system__spawn (on %* in /usr/bin/stap)
    sdt_stap:stap_system__fork (on %* in /usr/bin/stap)
    sdt_stap:intern_string (on %* in /usr/bin/stap)
    sdt_stap:client__start (on %* in /usr/bin/stap)
    sdt_stap:client__end (on %* in /usr/bin/stap)

  You can now use it in all perf tools, such as:

  	perf record -e sdt_stap:client__end -aR sleep 1

  #

From these we're use the two below to run systemtap's test suite:

  # perf record -e sdt_stap:pass2__*,cycles:P make installcheck > /dev/null
  ^C[ perf record: Woken up 8 times to write data ]
  [ perf record: Captured and wrote 2.691 MB perf.data (39638 samples) ]
  Terminated
  # perf script | grep sdt_stap
              stap 28979 [000] 19424.302660: sdt_stap:pass2__start: (561b9a537de3) arg1=140730364262544

Subject: perf map: Use zalloc for map_groups

In the next commit we will add new fields to map_groups and we need
these to be null if no value is assigned.  The simplest way to achieve
this is to request zeroed memory from the allocator.

Subject: perf unwind: Fix libunwind when tid != pid

Commit e5adfc3e7e77 ("perf map: Synthesize maps only for thread group
leader") changed the recording side so that we no longer get mmap events
for threads other than the thread group leader (when synthesising these
events for threads which exist before perf is started).

When a file recorded after this change is loaded, the lack of mmap
records mean that unwinding is not set up for any other threads.

This can be seen in a simple record/report scenario:

	perf record --call-graph=dwarf -t $TID
	perf report

If $TID is a process ID then the report will show call graphs, but if
$TID is a secondary thread the output is as if --call-graph=none was
specified.

Following the rationale in that commit, move the libunwind fields into
struct map_groups and update the libunwind functions to take this
instead of the struct thread.  This is only required for
unwind__finish_access which must now be called from map_groups__delete
and the others are changed for symmetry.

Note that unwind__get_entries keeps the thread argument since it is
required for symbol lookup and the libdw unwind provider uses the thread
ID.

Subject: perf unwind: Remove unnecessary test

If dwarf_callchain_users is false, then unwind__prepare_access() will
not set unwind_libunwind_ops so the remaining test here is sufficient.

Subject: selftests: Fix get_ifidx and callers in nettest.c

Dan reported:

    The patch acda655fefae: "selftests: Add nettest" from Aug 1, 2019,
    leads to the following static checker warning:

            ./tools/testing/selftests/net/nettest.c:1690 main()
            warn: unsigned 'tmp' is never less than zero.

    ./tools/testing/selftests/net/nettest.c
      1680                  case '1':
      1681                          args.has_expected_raddr = 1;
      1682                          if (convert_addr(&args, optarg,
      1683                                           ADDR_TYPE_EXPECTED_REMOTE))
      1684                                  return 1;
      1685
      1686                          break;
      1687                  case '2':
      1688                          if (str_to_uint(optarg, 0, 0x7ffffff, &tmp) != 0) {
      1689                                  tmp = get_ifidx(optarg);
      1690                                  if (tmp < 0) {

    "tmp" is unsigned so it can't be negative.  Also all the callers assume
    that get_ifidx() returns negatives on error but it looks like it really
    returns zero on error so it's a bit unclear to me.

Update get_ifidx to return -1 on errors and cleanup callers of it.

Fixed pep8/flake8 python style code for lsvmbus tool.

The TAB indentation was on purpose ignored (pep8 rule W191) to make
sure the code is complying with the Linux code guideline.
The following command doe not show any warnings now:
pep8 --ignore=W191 lsvmbus
flake8 --ignore=W191 lsvmbus

Subject: selftests: forwarding: devlink_lib: Allow tests to define devlink
 device

For tests that create their network interfaces dynamically or do not use
interfaces at all (as with netdevsim) it is useful to define their own
devlink device instead of deriving it from the first network interface.

Subject: selftests: devlink_trap: Add test cases for devlink-trap

Add test cases for devlink-trap on top of the netdevsim implementation.

The tests focus on the devlink-trap core infrastructure and user space
API. They test both good and bad flows and also dismantle of the netdev
and devlink device used to report trapped packets.

This allows device drivers to focus their tests on device-specific
functionality.

Subject: libbpf: add support for need_wakeup flag in AF_XDP part

This commit adds support for the new need_wakeup flag in AF_XDP. The
xsk_socket__create function is updated to handle this and a new
function is introduced called xsk_ring_prod__needs_wakeup(). This
function can be used by the application to check if Rx and/or Tx
processing needs to be explicitly woken up.

Subject: libbpf: relicense bpf_helpers.h and bpf_endian.h

bpf_helpers.h and bpf_endian.h contain useful macros and BPF helper
definitions essential to almost every BPF program. Which makes them
useful not just for selftests. To be able to expose them as part of
libbpf, though, we need them to be dual-licensed as LGPL-2.1 OR
BSD-2-Clause. This patch updates licensing of those two files.

Subject: selftests/bpf: fix race in test_tcp_rtt test

There is a race in this test between receiving the ACK for the
single-byte packet sent in the test, and reading the values from the
map.

This patch fixes this by having the client wait until there are no more
unacknowledged packets.

Before:
for i in {1..1000}; do ../net/in_netns.sh ./test_tcp_rtt; \
done | grep -c PASSED
< trimmed error messages >
993

After:
for i in {1..10000}; do ../net/in_netns.sh ./test_tcp_rtt; \
done | grep -c PASSED
10000

From c3bbf176fbad5d7470f8a4f311f7c11126ad36c2 Mon Sep 17 00:00:00 2001

Subject: selftests/bpf: add sockopt clone/inheritance test

Add a test that calls setsockopt on the listener socket which triggers
BPF program. This BPF program writes to the sk storage and sets
clone flag. Make sure that sk storage is cloned for a newly
accepted connection.

We have two cloned maps in the tests to make sure we hit both cases
in bpf_sk_storage_clone: first element (sk_storage_alloc) and
non-first element(s) (selem_link_map).

Subject: selftests: use "$(MAKE)" instead of "make"

When doing "make kselftest TARGETS=bpf -j12", bpf progs end up being
compiled sequentially and thus slowly.

The reason is that parent make (tools/testing/selftests/Makefile) does
not share its jobserver with child make
(tools/testing/selftests/bpf/Makefile), therefore the latter runs with
-j1.

Change all instances of "make" to "$(MAKE)", so that the whole make
hierarchy runs using a single jobserver.

Subject: tc-testing: use dedicated DUMMY interface name for dummy dev

A lot of tests reuse $DEV1 veth name for naming dummy device. This causes
problem when tdc is invoked without specifying a test group and tries to
execute all tests. In this case tdc instantiates ns plugin, which creates
veth pair once before running tests. However, if any of the tests that
reuse $DEV1 run before test that depend on ns plugin, it will delete $DEV1
as a part of teardown section:

=====> Test 3b88: Delete ingress qdisc twice                                                                                                                                                             [3770/41080]

adjust_command:  return command [ip netns exec tcut /sbin/ip link del dev v0p1 type dummy]
command "ip netns exec tcut /sbin/ip link del dev v0p1 type dummy"

After this ns-dependent tests will fail because dev doesn't exist:

---------------

Fix the issue by introducing standalone $DUMMY config variable and
substitute all usage of $DEV1 in tests that don't depend on ns plugin.

Subject: tc-testing: concurrency: wrap piped rule update commands

Concurrent tests use several commands to update rules in parallel: 'find'
prints names of batch files in tmp directory and pipes result to 'xargs'
which runs instance of tc per batch file in parallel. This breaks when used
with ns plugin that adds 'ip netns exec $NS' prefix to the command, which
causes only first command in pipe to be executed in namespace:

=====> Test e41d: Add 1M flower filters with 10 parallel tc instances
-----> prepare stage
ns/SubPlugin.adjust_command
adjust_command:  stage is setup; inserting netns stuff in command [/bin/mkdir tmp] list [['/bin/mkdir', 'tmp']]
adjust_command:  return command [ip netns exec tcut /bin/mkdir tmp]
command "ip netns exec tcut /bin/mkdir tmp"
ns/SubPlugin.adjust_command
adjust_command:  stage is setup; inserting netns stuff in command [/sbin/tc qdisc add dev ens1f0 ingress] list [['/sbin/tc', 'qdisc', 'add', 'dev', 'ens1f0', 'ingress']]
adjust_command:  return command [ip netns exec tcut /sbin/tc qdisc add dev ens1f0 ingress]
command "ip netns exec tcut /sbin/tc qdisc add dev ens1f0 ingress"
ns/SubPlugin.adjust_command
adjust_command:  stage is setup; inserting netns stuff in command [./tdc_multibatch.py ens1f0 tmp 100000 10 add] list [['./tdc_multibatch.py', 'ens1f0', 'tmp', '100000', '10', 'add']]
adjust_command:  return command [ip netns exec tcut ./tdc_multibatch.py ens1f0 tmp 100000 10 add]
command "ip netns exec tcut ./tdc_multibatch.py ens1f0 tmp 100000 10 add"
-----> execute stage
ns/SubPlugin.adjust_command
adjust_command:  stage is execute; inserting netns stuff in command [find tmp/add* -print | xargs -n 1 -P 10 /sbin/tc -b] list [['find', 'tmp/add*', '-print', '|', 'xargs', '-n', '1', '-P', '10', '/sbin/tc', '-b']
]
adjust_command:  return command [ip netns exec tcut find tmp/add* -print | xargs -n 1 -P 10 /sbin/tc -b]
command "ip netns exec tcut find tmp/add* -print | xargs -n 1 -P 10 /sbin/tc -b"

Fix the issue by executing whole compound command in namespace by wrapping
it in 'bash -c' invocation.

Subject: xfrm: policy: avoid warning splat when merging nodes

  sock_sendmsg net/socket.c:657 [inline]

There is no reproducer, however, the warning can be reproduced
by adding rules with ever smaller prefixes.

The sanity check ("does the policy match the node") uses the prefix value
of the node before its updated to the smaller value.

To fix this, update the prefix earlier.  The bug has no impact on tree
correctness, this is only to prevent a false warning.

Subject: memremap: remove the dev field in struct dev_pagemap

The dev field in struct dev_pagemap is only used to print dev_name in two
places, which are at best nice to have.  Just remove the field and thus
the name in those two messages.

Subject: perf tools: tools/include should come before tools/uapi/include

The next cset will grap const.h copies from the kernel to keep bits.h
in sync as it started to use linux/const.h, that in turn includes
uapi/linux/const.h.

So now we have a file with the same name in tools/include and
tools/uapi/include, and one includes the other, we need to have
tools/include/uapi/ after tools/include/ for this to work, fix it.

To pick up the changes in:

  f36cf386e3fe ("x86/speculation/swapgs: Exclude ATOMs from speculation through SWAPGS")
  18ec54fdd6d1 ("x86/speculation: Prepare entry code for Spectre v1 swapgs mitigations")

That don't affect anything in tools/.

This silences this perf build warning:

Subject: tools lib traceevent: Fix "robust" test of
 do_generate_dynamic_list_file
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The tools/lib/traceevent/Makefile had a test added to it to detect a failure
of the "nm" when making the dynamic list file (whatever that is). The
problem is that the test sorts the values "U W w" and some versions of sort
will place "w" ahead of "W" (even though it has a higher ASCII value, and
break the test.

Add 'tr "w" "W"' to merge the two and not worry about the ordering.

Subject: perf record: Enable LBR callstack capture jointly with thread stack

Enable '-j stack' applicability together with '--call-graph dwarf'
option so thread stack data and LBR call stack could be captured
jointly:

  $ perf record -g --call-graph dwarf,1024 -j stack,u -- stack_test

Collected LBR call stack can be used to augment DWARF call stack
calculated from the raw thread stack data and to provide more
comprehensive call stack information for cases when collected SIZE is
not enough to cover complete thread stack.

Such cases are typical for workloads that allocate large arrays of data
on its threads stacks or the possible SIZE to collect can't be large
enough due to workload nature or system configuration and this is where
hardware captured LBR call stacks can provide missing stack frames.
Possible DWARF plus LBR call stacks consolidation algorithm description
follows.

With this patch set perf report command UI currently ignores collected
LBR call stack data and still provides DWARF based call stacks
information.

Subject: perf report: Prefer DWARF callstacks to LBR ones when captured both

Display DWARF based callchains when the perf.data file contains raw thread
stack data as LBR callstack data.

Commiter testing:

This changes the output from the branch stack based one, i.e. without
this patch, for the same file as in the previous csets:

Subject: perf cs-etm: Support sample flags 'insn' and 'insnlen'

The synthetic branch and instruction samples are missed to set
instruction related info, thus the perf tool fails to display samples
with flags '-F,+insn,+insnlen'.

The CoreSight trace decoder provides sufficient information to decide
the instruction size based on the ISA type: A64/A32 instructions are
32-bit size, but one exception is the T32 instruction size, which might
be 32-bit or 16-bit.

This patch handles these cases and it reads the instruction values from
DSO file; thus can support the flags '-F,+insn,+insnlen'.

Before:

  # perf script -F,insn,insnlen,ip,sym
                0 [unknown] ilen: 0
     ffff97174044 _start ilen: 0
     ffff97174938 _dl_start ilen: 0
     ffff97174938 _dl_start ilen: 0
     ffff97174938 _dl_start ilen: 0
     ffff97174938 _dl_start ilen: 0
     ffff97174938 _dl_start ilen: 0
     ffff97174938 _dl_start ilen: 0
     ffff97174938 _dl_start ilen: 0
     ffff97174938 _dl_start ilen: 0

  [...]

After:

  # perf script -F,insn,insnlen,ip,sym
                0 [unknown] ilen: 0
     ffff97174044 _start ilen: 4 insn: 2f 02 00 94

We will not need it when refactoring this function to be

Subject: perf ui: Introduce non-interactive ui__info_window() function

Sometimes we want just to print a message on the center of the screen,
like in 'perf top' while we wait for the minimum amount of samples to be
collected before sorting and showing them.

Also expose __ui__info_window() as an optimization for cases where such
message is to be printed while holding the ui lock.

Subject: libperf: Fix arch include paths

Guenter Roeck reported problem with compilation when the ARCH is
specified:

  $ make ARCH=x86_64
  In file included from tools/include/asm/atomic.h:6:0,
                   from include/linux/atomic.h:5,

  fatal error: asm/cmpxchg.h: No such file or directory

The problem is that we don't use SRCARCH (the sanitized ARCH version)
and we don't get the proper include path.

Subject: Tools: hv: kvp: eliminate 'may be used uninitialized' warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When building hv_kvp_daemon GCC-8.3 complains:

hv_kvp_daemon.c: In function ‘kvp_get_ip_info.constprop’:
hv_kvp_daemon.c:812:30: warning: ‘ip_buffer’ may be used uninitialized in this function [-Wmaybe-uninitialized]
  struct hv_kvp_ipaddr_value *ip_buffer;

this seems to be a false positive: we only use ip_buffer when
op == KVP_OP_GET_IP_INFO and it is only unset when op == KVP_OP_ENUMERATE.

Silence the warning by initializing ip_buffer to NULL.

Subject: tools: bpftool: implement "bpftool btf show|list"

Add a "btf list" (alias: "btf show") subcommand to bpftool in order to
dump all BTF objects loaded on a system.

When running the command, hash tables are built in bpftool to retrieve
all the associations between BTF objects and BPF maps and programs. This
allows for printing all such associations when listing the BTF objects.

The command is added at the top of the subcommands for "bpftool btf", so
that typing only "bpftool btf" also comes down to listing the programs.
We could not have this with the previous command ("dump"), which
required a BTF object id, so it should not break any previous behaviour.
This also makes the "btf" command behaviour consistent with "prog" or
"map".

Bash completion is updated to use "bpftool btf" instead of "bpftool
prog" to list the BTF ids, as it looks more consistent.

Example output (plain):

    # bpftool btf show
    9: size 2989B  prog_ids 21  map_ids 15
    17: size 2847B  prog_ids 36  map_ids 30,29,28
    26: size 2847B

From 1446794a89c13816bd526dcbff4051cac9743db7 Mon Sep 17 00:00:00 2001
From: Todd Brandt <todd.e.brandt@linux.intel.com>

Subject: pm-graph v5.5

Upgrade bootgraph/sleepgraph to be able to run on python2 and python3.
Both now simply require python, the system can choose which to use.

bootgraph python3 update:
- add floor function to handle integer arithmetic
- change argument loop to use next() instead of args.next()
- open dmesg log and popen in binary, use decode(ascii, ignore)
- sort all html data to allow diff between python versions
- change exception handler to use python3 as instead of comma

sleepgraph python3 update:
- import configparser not ConfigParser (p2 needs python-configparser)
- add floor function to handle integer arithmetic
- change argument loop to use next() instead of args.next()
- handle popen output in binary, use decode(ascii, ignore)
- sort all html/output data to allow diff between python versions
- force gzip open to use text mode, same for file open
- ensure no binary data is written to logs (ascii convert devprops info)
- use codecs library to handle zlib encoding for mcelog data
- remove all uses of python3.7 keyword "async" as members or vars
- assume all FPDT and DMI data is in binary string form

sleepgraph:
- turbostat will be used by default if it's found & the mode is freeze
- a new option "-noturbostat" will disable its use
- fix bug where two callgraphs with the same start time overwrite.
- fix s2idle processing where two suspend/resume_machines occur back2back
- update getexec function to use which first (assuming PATH exists)
- new platforminfo data in log with: lspci, gpe counts, /proc/interrupts
- new data is zipped, b64 encoded, and tacked on the end of ftrace

Subject: selftests: kvm: fix state save/load on processors without XSAVE

state_test and smm_test are failing on older processors that do not
have xcr0.  This is because on those processor KVM does provide
support for KVM_GET/SET_XSAVE (to avoid having to rely on the older
KVM_GET/SET_FPU) but not for KVM_GET/SET_XCRS.

Subject: libbpf: use LFS (_FILE_OFFSET_BITS) instead of direct mmap2 syscall

Drop __NR_mmap2 fork in flavor of LFS, that is _FILE_OFFSET_BITS=64
(glibc & bionic) / LARGEFILE64_SOURCE (for musl) decision. It allows
mmap() to use 64bit offset that is passed to mmap2 syscall. As result
pgoff is not truncated and no need to use direct access to mmap2 for
32 bits systems.

Subject: selftests/bpf: fix test_cgroup_storage on s390

test_cgroup_storage fails on s390 with an assertion failure: packets are
dropped when they shouldn't. The problem is that BPF_DW packet count is
accessed as BPF_W with an offset of 0, which is not correct on
big-endian machines.

Since the point of this test is not to verify narrow loads/stores,
simply use BPF_DW when working with packet counts.

Fixes: 68cfa3ac6b8d ("selftests/bpf: add a cgroup storage test")

Subject: selftests/bpf: fix test_btf_dump with O=

test_btf_dump fails when run with O=, because it needs to access source
files and assumes they live in ./progs/, which is not the case in this
scenario.

Fix by instructing kselftest to copy btf_dump_test_case_*.c files to the
test directory. Since kselftest does not preserve directory structure,
adjust the test to look in ./progs/ and then in ./.

test_msr_platform_info_disabled() generates EXIT_SHUTDOWN but VMCB state
is undefined after that so an attempt to launch this guest again from
test_msr_platform_info_enabled() fails. Reorder the tests to make test
pass.

Subject: tools: bpftool: show frozen status for maps

When listing maps, read their "frozen" status from procfs, and tell if
maps are frozen.

As commit log for map freezing command mentions that the feature might
be extended with flags (e.g. for write-only instead of read-only) in the
future, use an integer and not a boolean for JSON output.

Subject: selftests: mlxsw: Add a test case for devlink-trap

Test generic devlink-trap functionality over mlxsw. These tests are not
specific to a single trap, but do not check the devlink-trap common
infrastructure either.

Currently, the only test case is device deletion (by reloading the
driver) while packets are being trapped.

Subject: selftests/powerpc: Ignore generated files

Currently some binary files which are generated when tests are compiled
are not ignored by git, so 'git status' catch them.

For copyloops test, fix wrong binary names already in .gitignore. For
ptrace, security, and stringloops tests add missing binary names to the
.gitignore file.

Subject: perf tools: Use perf_cpu_map__nr instead of cpu_map__nr

Switch the rest of the perf code to use libperf's perf_cpu_map__nr(),
which is the same as current cpu_map__nr() and remove the cpu_map__nr()
function.

From 315c0a1f0ccdd44c65f80ccbc62202fed8a23050 Mon Sep 17 00:00:00 2001
From: Jiri Olsa <jolsa@kernel.org>
Date: Thu, 22 Aug 2019 13:11:39 +0200
Subject: libperf: Move perf's cpu_map__empty() to perf_cpu_map__empty()

So it's part of the libperf library as one of basic functions operating
on the perf_cpu_map class.

It uses strstr(), needs to include string.h or its not going to build
when we remove string.h from the place it is getting from indirectly, by

There we need just some struct forward declarations, do that instead and
add the includes needed by metricgroup.c.

That should help with needless rebuilds when changing the removed

 dep tree

All we need in util/evsel.h is the foward declaration of 'struct
xyarray', not the internal/xyarray.h, that can be moved to util/evsel.c
and then we reduce the header dependency tree.

Since util/evsel.h uses perf_evsel__cpus() that has its prototype in
libperf's perf/evsel.h file, we need it explicitely included.

This was working by luck as util/evsel.h includes counts.h, but that is
not necessary, just some forward declarations, so, before we remove
counts.h from util/evsel.h, add what is realli needed.

Subject: perf evsel: Remove needless stddef.h from util/evsel.h

We added it in 07ac002f2fcc ("perf evsel: Introduce is_group_member
method") but we already ditched that function, and there was nothing
else left that needed NULL nor anything else from stddef.h, ditch it.

Subject: perf evsel: util/evsel.h needs stdio.h as it uses FILE

And it was getting it by luck from util/cpumap.h that shouldn't be
included in util/evsel.h as it only needs what is in libperf, i.e.
struct cpu_map, that is in internal/cpumap.h, so add stdio.h before
we fix that.

Subject: perf x86 kvm-stat: Add missing string.h header

It uses strcmp(), strstr() and was getting the required string.h header
by luck, from evsel.h -> cpumap.h -> debug.h -> string.h, add the
missing header.

Subject: perf evsel: Switch to libperf's cpumap.h
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We don't need what is in perf's util/cpumap.h, just the struct cpu_map
that is in libperf's internal/cpumap.h file to cover this one case:

  tools/perf/util/evsel.h:215:27: error: dereferencing pointer to incomplete type ‘struct perf_cpu_map’
  215 |  return evsel__cpus(evsel)->nr;

So switch to libperf's cpumap.h and add some missing struct foward
declarations and include sys/types.h to get pid_t.

Subject: perf cpumap: Remove needless includes from cpumap.h

The util/cpumap.h file doesn't use anything in refcount.h not in
debug.h, it needs just a forward reference to 'struct cpu_map_data',
that is defined in util/event.h and cpumap.h was getting indirectly via,
of all things, debug.h

Subject: perf c2c: Fix report with offline cpus

If c2c is recorded on a machine where any cpus are offline, 'perf c2c
report' throws an error "node/cpu topology bugFailed setup nodes".

It fails because while preparing node-cpu mapping we don't consider
offline cpus.

Subject: libperf: Fix alignment trap with xyarray contents in 'perf stat'

Following the patch 'perf stat: Fix --no-scale', an alignment trap
happens in process_counter_values() on ARMv7 platforms due to the
attempt to copy non 64 bits aligned double words (pointed by 'count')
via a NEON vectored instruction ('vld1' with 64 bits alignment
constraint).

This patch sets a 64 bits alignment constraint on 'contents[]' field in
'struct xyarray' since the 'count' pointer used above points to such a
structure.

Subject: selftests/powerpc: Fix and enhance TM signal context tests

Currently TM signal context tests for GPR, FPR, VMX, and VSX registers
print wrong register numbers (wrongly starting from register 0 instead
of the first register in the non-volatile subset). Besides it the
output when a mismatch happens is poor giving not much information
about which context and which register mismatches, because it prints
both contexts at the same time and not a comparison between the value
that mismatches and the value expected and, moreover, it stops
printing on the first mismatch, but it's important to know if there
are other mismatches happening beyond the first one.

For instance, this is the current output when a mismatch happens:

  test: tm_signal_context_chk_gpr
  tags: git_version:v5.2-8249-g02e970fae465-dirty
  Failed on 0 GPR 1 or 18446744073709551615

  Failed on 0 vsx 0xfffffffffefffffffdfffffffcffffff vs 0xfffffffffefffffffdfffffffcffffff
  failure: tm_signal_context_chk_vsx

This commit fixes the register numbers printed and enhances the error
output by providing a full list of mismatching registers separated by
the context (non-speculative or speculative context), for example:

TM test tm-unavailable must take into account aborts due to host aborting
a transactin because of a facility unavailable exception, just like it
already does for aborts on reschedules (TM_CAUSE_KVM_RESCHED).

Subject: perf cpumap: No need to include perf.h, ditch it

From a quick look this was never needed and just polluted the build,
needlessly making things including cpumap.h to be rebuild if perf.h or
anything it includes gets changed.

Subject: perf srcline: Add missing srcline.h header to files needing its defs

When srcline was introduced it wrongly added the include to util/sort.h,
even with that header not needing the definitions it provides, fix it by
adding it to the places that need it as a pre patch to remove srcline.h
from sort.h.

Reducing the includes hell a bit more, speeding up the build and
avoiding needless rebuilds when just one of those files gets updated.

Subject: perf tests: Fixes hang in zstd compression test by changing the
 source of random data

Running 'perf test' with zstd compression linked will hang at the test
'Zstd perf.data compression/decompression' because /dev/random blocks
reads until there is enough entropy. This means that the test will
appear to never complete unless the mouse is continually moved while
running it.

Subject: perf trace beauty ioctl: Fix off-by-one error in cmd->string table

While tracing a program that calls isatty(3), I noticed that strace
reported TCGETS for the request argument of the underlying ioctl(2)
syscall while perf trace reported TCSETS. strace is corrrect. The bug in
perf was due to the tty ioctl beauty table starting at 0x5400 rather
than 0x5401.

Committer testing:

  Using augmented_raw_syscalls.o and settings to make 'perf trace'
  use strace formatting, i.e. with this in ~/.perfconfig

  # cat ~/.perfconfig
  [trace]
	add_events = /home/acme/git/linux/tools/perf/examples/bpf/augmented_raw_syscalls.c
	show_zeros = yes
	show_duration = no
	no_inherit = yes
	show_timestamp = no
	show_arg_names = no
	args_alignment = 40
	show_prefix = yes

  # strace -e ioctl stty > /dev/null
  ioctl(0, TCGETS, {B38400 opost isig icanon echo ...}) = 0
  ioctl(1, TIOCGWINSZ, 0x7fff8a9b0860)    = -1 ENOTTY (Inappropriate ioctl for device)
  ioctl(1, TCGETS, 0x7fff8a9b0540)        = -1 ENOTTY (Inappropriate ioctl for device)
  +++ exited with 0 +++
  #

Before:

  # perf trace -e ioctl stty > /dev/null
  ioctl(0, TCSETS, 0x7fff2cf79f20)        = 0
  ioctl(1, TIOCSWINSZ, 0x7fff2cf79f40)    = -1 ENOTTY (Inappropriate ioctl for device)
  ioctl(1, TCSETS, 0x7fff2cf79c20)        = -1 ENOTTY (Inappropriate ioctl for device)
  #

After:

  # perf trace -e ioctl stty > /dev/null
  ioctl(0, TCGETS, 0x7ffed0763920)        = 0
  ioctl(1, TIOCGWINSZ, 0x7ffed0763940)    = -1 ENOTTY (Inappropriate ioctl for device)
  ioctl(1, TCGETS, 0x7ffed0763620)        = -1 ENOTTY (Inappropriate ioctl for device)

We need more than the BPF stack can give us to format the
raw_syscalls:sys_enter augmented tracepoint, so we use a PERCPU_ARRAY

Subject: perf augmented_raw_syscalls: Reduce perf_event_output() boilerplate

Add a augmented__output() helper to reduce the boilerplate of sending
the augmented tracepoint to the PERF_EVENT_ARRAY BPF map associated with
the bpf-output event used to communicate with the userspace perf trace
tool.

Date: Sun, 25 Aug 2019 20:17:41 +0200
Subject: libperf: Add PERF_RECORD_MMAP 'struct mmap_event' to perf/event.h

Move the mmap_event event definition to libperf's event.h header
include.

In order to keep libperf simple, we switch 'u64/u32/u16/u8' types used
events to their generic '__u*' versions.

Perf added 'u*' types mainly to ease up printing __u64 values as stated
in the linux/types.h comment:

  /*
   * We define u64 as uint64_t for every architecture
   * so that we can print it with "%"PRIx64 without getting warnings.
   *
   * typedef __u64 u64;
   * typedef __s64 s64;
   */

Add  and use new PRI_lu64 and PRI_lx64 macros for that.  Use extra '_'
to ease up reading and differentiate them from standard PRI*64 macros.

Committer notes:

Fixup the PRI_l[ux]64 macros on 32-bit arches, conditionally defining it
with that extra 'l' modifier only on arches where __u64 is long long,
leaving it aside on 32-bit arches.

From b66ced19c9f64dbe707cf318fae9fca82b999564 Mon Sep 17 00:00:00 2001
From: Jiri Olsa <jolsa@kernel.org>
Date: Sun, 25 Aug 2019 20:17:42 +0200
Subject: libperf: Add PERF_RECORD_MMAP2 'struct mmap2_event' to perf/event.h

Moving mmap2_event event definition into libperf's event.h header
include.

In order to keep libperf simple, we switch 'u64/u32/u16/u8' types used
events to their generic '__u*' versions.

Perf added 'u*' types mainly to ease up printing __u64 values
as stated in the linux/types.h comment:

  /*
   * We define u64 as uint64_t for every architecture
   * so that we can print it with "%"PRIx64 without getting warnings.
   *
   * typedef __u64 u64;
   * typedef __s64 s64;
   */

Adding and using new PRI_lu64 and PRI_lx64 macros to be used for
that.  Using extra '_' to ease up the reading and differentiate
them from standard PRI*64 macros.

Add and use new PRI_lu64 and PRI_lx64 macros for that.  Use extra '_' to
ease up the reading and differentiate them from standard PRI*64 macros.

From 69d81f09e1607b577346c0579bf938c1194bff3a Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Date: Mon, 26 Aug 2019 19:02:31 -0300
Subject: libperf: Rename the PERF_RECORD_ structs to have a "perf" suffix

Even more, to have a "perf_record_" prefix, so that they match the
PERF_RECORD_ enum they map to.

Copy-paste of existing test
"calls: cross frame pruning - liveness propagation"
but ran with different parentage chain heuristic
which stresses different path in precision tracking logic.

From d38835b75f67df16cef65c14aa64796a1832e6b4 Mon Sep 17 00:00:00 2001
From: Stanislav Fomichev <sdf@google.com>
Date: Wed, 21 Aug 2019 16:44:25 -0700
Subject: selftests/bpf: test_progs: remove global fail/success counts

Now that we have a global per-test/per-environment state, there
is no longer need to have global fail/success counters (and there
is no need to save/get the diff before/after the test).

Introduce CHECK_FAIL macro (suggested by Andrii) and covert existing tests
to it. CHECK_FAIL uses new test__fail() to record the failure.

Subject: selftests/bpf: remove wrong nhoff in flow dissector test

.nhoff = 0 is (correctly) reset to ETH_HLEN on the next line so let's
drop it.

Subject: x86/intel: Aggregate big core client naming

Currently the big core client models either have:

 - no OPTDIFF
 - _CORE
 - _DESKTOP

Make it uniformly: 'no OPTDIFF'.

for i in `git grep -l "\(INTEL_FAM6_\|VULNWL_INTEL\|INTEL_CPU_FAM6\).*_\(CORE\|DESKTOP\)"`
do
	sed -i -e 's/\(\(INTEL_FAM6_\|VULNWL_INTEL\|INTEL_CPU_FAM6\).*\)_\(CORE\|DESKTOP\)/\1/g' ${i}
done

Subject: x86/intel: Aggregate big core mobile naming

Currently big core mobile chips have either:

 - _L
 - _ULT
 - _MOBILE

Make it uniformly: _L.

for i in `git grep -l "\(INTEL_FAM6_\|VULNWL_INTEL\|INTEL_CPU_FAM6\).*_\(MOBILE\|ULT\)"`
do
	sed -i -e 's/\(\(INTEL_FAM6_\|VULNWL_INTEL\|INTEL_CPU_FAM6\).*\)_\(MOBILE\|ULT\)/\1_L/g' ${i}
done

Subject: x86/intel: Aggregate big core graphics naming

Currently big core clients with extra graphics on have:

 - _G
 - _GT3E

Make it uniformly: _G

for i in `git grep -l "\(INTEL_FAM6_\|VULNWL_INTEL\|INTEL_CPU_FAM6\).*_GT3E"`
do
	sed -i -e 's/\(\(INTEL_FAM6_\|VULNWL_INTEL\|INTEL_CPU_FAM6\).*\)_GT3E/\1_G/g' ${i}
done

From 5ebb34edbefa8ea6a7e109179d5fc7b3529dbeba Mon Sep 17 00:00:00 2001
From: Peter Zijlstra <peterz@infradead.org>

Subject: x86/intel: Aggregate microserver naming

Currently big microservers have _XEON_D while small microservers have
_X, Make it uniformly: _D.

for i in `git grep -l "\(INTEL_FAM6_\|VULNWL_INTEL\|INTEL_CPU_FAM6\).*_\(X\|XEON_D\)"`
do
	sed -i -e 's/\(\(INTEL_FAM6_\|VULNWL_INTEL\|INTEL_CPU_FAM6\).*ATOM.*\)_X/\1_D/g' \
	       -e 's/\(\(INTEL_FAM6_\|VULNWL_INTEL\|INTEL_CPU_FAM6\).*\)_XEON_D/\1_D/g' ${i}
done

Subject: perf evsel: Kernel profiling is disallowed only when
 perf_event_paranoid > 1

Perf was too restrictive about sysctl kernel.perf_event_paranoid. The
kernel only disallows profiling when perf_event_paranoid > 1. Make perf
do the same.

Committer testing:

For a non-root user:

  $ id
  uid=1000(acme) gid=1000(acme) groups=1000(acme),10(wheel) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
  $

Before:

We were restricting it to just userspace (:u suffix) even for a
workload started by the user:

  $ perf record sleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.001 MB perf.data (8 samples) ]
  $ perf evlist
  cycles:u
  $ perf evlist -v
  cycles:u: size: 112, { sample_period, sample_freq }: 4000, sample_type: IP|TID|TIME|PERIOD, read_format: ID, disabled: 1, inherit: 1, exclude_kernel: 1, mmap: 1, comm: 1, freq: 1, enable_on_exec: 1, task: 1, precise_ip: 3, sample_id_all: 1, exclude_guest: 1, mmap2: 1, comm_exec: 1, ksymbol: 1, bpf_event: 1
  $ perf report --stdio
  # To display the perf.data header info, please use --header/--header-only options.
  #
  # Total Lost Samples: 0
  #
  # Samples: 8  of event 'cycles:u'
  # Event count (approx.): 1040396
  #
  # Overhead  Command  Shared Object     Symbol
  # ........  .......  ................  ......................
  #
      68.36%  sleep    libc-2.29.so      [.] _dl_addr
      27.33%  sleep    ld-2.29.so        [.] dl_main
       3.80%  sleep    ld-2.29.so        [.] _dl_setup_hash
  #
  # (Tip: Order by the overhead of source file name and line number: perf report -s srcline)
  #
  $
  $

After:

When the kernel allows profiling the kernel in that scenario:

  $ perf record sleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.023 MB perf.data (11 samples) ]
  $ perf evlist
  cycles
  $ perf evlist -v
  cycles: size: 112, { sample_period, sample_freq }: 4000, sample_type: IP|TID|TIME|PERIOD, read_format: ID, disabled: 1, inherit: 1, mmap: 1, comm: 1, freq: 1, enable_on_exec: 1, task: 1, precise_ip: 3, sample_id_all: 1, exclude_guest: 1, mmap2: 1, comm_exec: 1, ksymbol: 1, bpf_event: 1
  $
  $ perf report --stdio
  # To display the perf.data header info, please use --header/--header-only options.
  #
  # Total Lost Samples: 0
  #

Subject: perf symbols: Use CAP_SYSLOG with kptr_restrict checks

The kernel is using CAP_SYSLOG capability instead of uid==0 and euid==0
when checking kptr_restrict. Make perf do the same.

Also, the kernel is a more restrictive than "no restrictions" in case of
kptr_restrict==0, so add the same logic to perf.

Subject: perf evlist: Remove needless util.h from evlist.h

There is no need for that util/util.h include there and, remove it,
pruning the include tree, fix the fallout by adding necessary headers to
places that were getting needed includes indirectly from evlist.h ->
util.h.

Subject: perf clang: Delete needless util-cxx.h header

It was put in place just to make sure the 'new' C++ operator wouldn't
clash with some argument name in util.h, but there is not anymore any
such argument and also the reason stated for util.h to be included there
was to get the __maybe_unused definition, that is in linux/compiler.h,
so use that instead and nuke util-cxx.h.

Subject: perf top: Decay all events in the evlist

Currently perf top only decays entries in a selected evsel.  I don't
know whether it's intended (maybe due to performance reason?) but anyway
it might show incorrect output when event group is used since users will
see leader event is decayed but others are not.

This patch moves the decay code into perf_top__resort_hists() so that
stdio and TUI code shared the logic.

Subject: perf top: Fix event group with more than two events

The event group feature links relevant hist entries among events so that
they can be displayed together.  During the link process, each hist
entry in non-leader events is connected to a hist entry in the leader
event.  This is done in order of events specified in the command line so
it assumes that events are linked in the order.

But 'perf top' can break the assumption since it does the link process
multiple times.  For example, a hist entry can be in the third event
only at first so it's linked after the leader.  Some time later, second
event has a hist entry for it and it'll be linked after the entry of the
third event.

This makes the code compilicated to deal with such unordered entries.
This patch simply unlink all the entries after it's printed so that they
can assume the correct order after the repeated link process.  Also it'd
be easy to deal with decaying old entries IMHO.

Subject: libperf: Add PERF_RECORD_AUXTRACE_INFO 'struct auxtrace_info_event'
 to perf/event.h

Move the PERF_RECORD_AUXTRACE_INFO event definition to libperf's
event.h.

In order to keep libperf simple, we switch 'u64/u32/u16/u8' types used
events to their generic '__u*' versions.

Subject: libperf: Add PERF_RECORD_HEADER_FEATURE 'struct feature_event' to
 perf/event.h

Move the PERF_RECORD_HEADER_FEATURE event definition to libperf's
event.h.

In order to keep libperf simple, we switch 'u64/u32/u16/u8' types used
events to their generic '__u*' versions.

Subject: perf evlist: Use unshare(CLONE_FS) in sb threads to let
 setns(CLONE_NEWNS) work

When we started using a thread to catch the PERF_RECORD_BPF_EVENT meta
data events to then ask the kernel for further info (BTF, etc) for BPF
programs shortly after they get loaded, we forgot to use
unshare(CLONE_FS) as was done in:

  868a832918f6 ("perf top: Support lookup of symbols in other mount namespaces.")

Do it so that we can enter the namespaces to read the build-ids at the
end of a 'perf record' session for the DSOs that had hits.

Before:

Starting a 'stress-ng --cpus 8' inside a container and then, outside the
container running:

  # perf record -a --namespaces sleep 5
  # perf buildid-list | grep stress-ng
  #

We would end up with a 'perf.data' file that had no entry in its
build-id table for the /usr/bin/stress-ng binary inside the container
that got tons of PERF_RECORD_SAMPLEs.

After:

  # perf buildid-list | grep stress-ng
  f2ed02c68341183a124b9b0f6e2e6c493c465b29 /usr/bin/stress-ng
  #

Then its just a matter of making sure that that binary debuginfo package
gets available in a place that 'perf report' will look at build-id keyed
ELF files, which, in my case, on a f30 notebook, was a matter of
installing the debuginfo file for the distro used in the container,
fedora 31:

  # rpm -ivh http://fedora.c3sl.ufpr.br/linux/development/31/Everything/x86_64/debug/tree/Packages/s/stress-ng-debuginfo-0.07.29-10.fc31.x86_64.rpm

Then, because perf currently looks for those debuginfo files (richer ELF
symtab) inside that namespace (look at the setns calls):

  openat(AT_FDCWD, "/proc/self/ns/mnt", O_RDONLY) = 137
  openat(AT_FDCWD, "/proc/13169/ns/mnt", O_RDONLY) = 139
  setns(139, CLONE_NEWNS)                 = 0
  stat("/usr/bin/stress-ng", {st_mode=S_IFREG|0755, st_size=3065416, ...}) = 0
  openat(AT_FDCWD, "/usr/bin/stress-ng", O_RDONLY) = 140
  fcntl(140, F_GETFD)                     = 0
  fstat(140, {st_mode=S_IFREG|0755, st_size=3065416, ...}) = 0
  mmap(NULL, 3065416, PROT_READ, MAP_PRIVATE, 140, 0) = 0x7ff2fdc5b000
  munmap(0x7ff2fdc5b000, 3065416)         = 0
  close(140)                              = 0
  stat("stress-ng-0.07.29-10.fc31.x86_64.debug", 0x7fff45d71260) = -1 ENOENT (No such file or directory)
  stat("/usr/bin/stress-ng-0.07.29-10.fc31.x86_64.debug", 0x7fff45d71260) = -1 ENOENT (No such file or directory)

To only then go back to the "host" namespace to look just in the users's
~/.debug cache:

  setns(137, CLONE_NEWNS)                 = 0
  chdir("/root")                          = 0
  close(137)                              = 0
  close(139)                              = 0
  stat("/root/.debug/.build-id/f2/ed02c68341183a124b9b0f6e2e6c493c465b29/elf", 0x7fff45d732e0) = -1 ENOENT (No such file or directory)

It continues to fail to resolve symbols:

  # perf report | grep stress-ng | head -5
     9.50%  stress-ng-cpu    stress-ng    [.] 0x0000000000021ac1
     8.58%  stress-ng-cpu    stress-ng    [.] 0x0000000000021ab4
     8.51%  stress-ng-cpu    stress-ng    [.] 0x0000000000021489

     3.93%  stress-ng-cpu    stress-ng    [.] 0x0000000000021478
  #

To overcome that we use:

  # perf buildid-cache -v --add /usr/lib/debug/usr/bin/stress-ng-0.07.29-10.fc31.x86_64.debug
  Adding f2ed02c68341183a124b9b0f6e2e6c493c465b29 /usr/lib/debug/usr/bin/stress-ng-0.07.29-10.fc31.x86_64.debug: Ok
  #
  # ls -la /root/.debug/.build-id/f2/ed02c68341183a124b9b0f6e2e6c493c465b29/elf
  -rw-r--r--. 3 root root 2401184 Jul 27 07:03 /root/.debug/.build-id/f2/ed02c68341183a124b9b0f6e2e6c493c465b29/elf
  # file /root/.debug/.build-id/f2/ed02c68341183a124b9b0f6e2e6c493c465b29/elf
  /root/.debug/.build-id/f2/ed02c68341183a124b9b0f6e2e6c493c465b29/elf: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter \004, BuildID[sha1]=f2ed02c68341183a124b9b0f6e2e6c493c465b29, for GNU/Linux 3.2.0, with debug_info, not stripped, too many notes (256)
  #

Now it finally works:

  # perf report | grep stress-ng | head -5
    23.59%  stress-ng-cpu    stress-ng    [.] ackermann
    23.33%  stress-ng-cpu    stress-ng    [.] is_prime
    17.36%  stress-ng-cpu    stress-ng    [.] stress_cpu_sieve
     6.08%  stress-ng-cpu    stress-ng    [.] stress_cpu_correlate
     3.55%  stress-ng-cpu    stress-ng    [.] queens_try
  #

I'll make sure that it looks for the build-id keyed files in both the
"host" namespace (the namespace the user running 'perf record' was a the
time of the recording) and in the container namespace, as it shouldn't
matter where a content based key lookup finds the ELF file to use in
resolving symbols, etc.

Subject: tools lib traceevent: Do not free tep->cmdlines in add_new_comm() on
 failure

If the re-allocation of tep->cmdlines succeeds, then the previous
allocation of tep->cmdlines will be freed. If we later fail in
add_new_comm(), we must not free cmdlines, and also should assign
tep->cmdlines to the new allocation. Otherwise when freeing tep, the
tep->cmdlines will be pointing to garbage.

Subject: tools lib traceevent: Remove unneeded qsort and uses memmove instead

While reading a trace data file that had 100,000s of tasks, the process
took an extremely long time. I profiled it down to add_new_comm(), which
was doing a qsort() call on an array that was pretty much already sorted
(all but the last element. qsort() isn't very efficient when dealing
with mostly sorted arrays, and this definitely showed its issues.

When adding a new task to the task list, instead of using qsort(), do
another bsearch() with a function that will find the element before
where the new task will be inserted in. Then simply shift the rest of
the array, and insert the task where it belongs.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

When cross-compiling cpupower, 64bit detection is done with the host
compiler instead of the cross-compiler and libcpupower.so.0 ends up in
/usr/lib64 instead of /usr/lib for 32bit target.  Fix this by moving
64bit detection after CC is defined.

Subject: sefltest/ima: support appended signatures (modsig)

In addition to the PE/COFF and IMA xattr signatures, the kexec kernel
image can be signed with an appended signature, using the same
scripts/sign-file tool that is used to sign kernel modules.

This patch adds support for detecting a kernel image signed with an
appended signature and updates the existing test messages
appropriately.

Subject: perf c2c: Display proper cpu count in nodes column

There's wrong bitmap considered when checking for cpu count of specific
node.

We do the needed computation for 'set' variable, but at the end we use
the 'c2c_he->cpuset' weight, which shows misleading numbers.

Subject: perf timechart: Refactor svg_build_topology_map()

Exchange the parameters of svg_build_topology_map() with 'struct
perf_env *env' and adjust the function accordingly.

This patch should not change any behavior, it is merely refactoring for
the following patch.

Committer notes:

No need to include env.h from svghelper.h, all it needs is a forward
declaration for 'struct perf_env', so move the include directive to
svghelper.c, where it is really needed.

Subject: perf svghelper: Replace MAX_NR_CPUS with perf_env::nr_cpus_online

'nr_cpus', the number of CPUs online during a record session bound by
MAX_NR_CPUS, can be used as a dynamic alternative for MAX_NR_CPUS in
svg_build_topology_map().

The value of nr_cpus can be passed into str_to_bitmap(),
scan_core_topology(), and svg_build_topology_map() to replace
MAX_NR_CPUS as well.

Subject: perf stat: Replace MAX_NR_CPUS with cpu__max_cpu()

The function cpu__max_cpu() returns the possible number of CPUs as
defined in the sysfs and can be used as an alternative for MAX_NR_CPUS
in zero_per_pkg() and check_per_pkg().

From 0ac25fd0a04d8bd52ceac2476e71a4e497489987 Mon Sep 17 00:00:00 2001

Subject: perf tools: Remove perf.h from source files not needing it

ended up not needing it in lots of places, remove it from those places.

From b42090256fba05dce1a0482a4ccd9bb6464cc499 Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Date: Thu, 29 Aug 2019 15:56:40 -0300
Subject: perf tools: Remove debug.h from header files not needing it

And fix the fallout, adding it to places that must have it since they
use its definitions.

From d78c620a2e824d7b01a6e991208a8aa2c938cabe Mon Sep 17 00:00:00 2001
From: Dan Williams <dan.j.williams@intel.com>
Date: Mon, 26 Aug 2019 17:54:54 -0700
Subject: libnvdimm/security: Introduce a 'frozen' attribute

In the process of debugging a system with an NVDIMM that was failing to
unlock it was found that the kernel is reporting 'locked' while the DIMM
security interface is 'frozen'. Unfortunately the security state is
tracked internally as an enum which prevents it from communicating the
difference between 'locked' and 'locked + frozen'. It follows that the
enum also prevents the kernel from communicating 'unlocked + frozen'
which would be useful for debugging why security operations like 'change
passphrase' are disabled.

Ditch the security state enum for a set of flags and introduce a new
sysfs attribute explicitly for the 'frozen' state. The regression risk
is low because the 'frozen' state was already blocked behind the
'locked' state, but will need to revisit if there were cases where
applications need 'frozen' to show up in the primary 'security'
attribute. The expectation is that communicating 'frozen' is mostly a
helper for debug and status monitoring.

Subject: tools: bpftool: ignore make built-in rules for getting kernel version

Bpftool calls the toplevel Makefile to get the kernel version for the
sources it is built from. But when the utility is built from the top of
the kernel repository, it may dump the following error message for
certain architectures (including x86):

    $ make tools/bpf
    [...]
    make[3]: *** [checkbin] Error 1
    [...]

This does not prevent bpftool compilation, but may feel disconcerting.
The "checkbin" arch-dependent target is not supposed to be called for
target "kernelversion", which is a simple "echo" of the version number.

It turns out this is caused by the make invocation in tools/bpf/bpftool,
which attempts to find implicit rules to apply. Extract from debug
output:

To avoid that, pass the -r and -R flags to eliminate the use of make
built-in rules (and while at it, built-in variables) when running
command "make kernelversion" from bpftool's Makefile.

Subject: tools: bpftool: improve and check builds for different make
 invocations

There are a number of alternative "make" invocations that can be used to
compile bpftool. The following invocations are expected to work:

  - through the kbuild system, from the top of the repository
    (make tools/bpf)
  - by telling make to change to the bpftool directory
    (make -C tools/bpf/bpftool)
  - by building the BPF tools from tools/
    (cd tools && make bpf)
  - by running make from bpftool directory
    (cd tools/bpf/bpftool && make)

Additionally, setting the O or OUTPUT variables should tell the build
system to use a custom output path, for each of these alternatives.

The following patch fixes the following invocations:

  $ make tools/bpf
  $ make tools/bpf O=<dir>
  $ make -C tools/bpf/bpftool OUTPUT=<dir>
  $ make -C tools/bpf/bpftool O=<dir>
  $ cd tools/ && make bpf O=<dir>
  $ cd tools/bpf/bpftool && make OUTPUT=<dir>
  $ cd tools/bpf/bpftool && make O=<dir>

After this commit, the build still fails for two variants when passing
the OUTPUT variable:

  $ make tools/bpf OUTPUT=<dir>
  $ cd tools/ && make bpf OUTPUT=<dir>

In order to remember and check what make invocations are supposed to
work, and to document the ones which do not, a new script is added to
the BPF selftests. Note that some invocations require the kernel to be
configured, so the script skips them if no .config file is found.

v2:
- In make_and_clean(), set $ERROR to 1 when "make" returns non-zero,
  even if the binary was produced.
- Run "make clean" from the correct directory (bpf/ instead of bpftool/,
  when relevant).

Subject: tools: bpf: account for generated feature/ and libbpf/ directories

When building "tools/bpf" from the top of the Linux repository, the
build system passes a value for the $(OUTPUT) Makefile variable to
tools/bpf/Makefile and tools/bpf/bpftool/Makefile, which results in
generating "libbpf/" (for bpftool) and "feature/" (bpf and bpftool)
directories inside the tree.

This commit adds such directories to the relevant .gitignore files, and
edits the Makefiles to ensure they are removed on "make clean". The use
of "rm" is also made consistent throughout those Makefiles (relies on
the $(RM) variable, use "--" to prevent interpreting

Subject: tools: bpftool: do not link twice against libbpf.a in Makefile

In bpftool's Makefile, $(LIBS) includes $(LIBBPF), therefore the library
is used twice in the linking command. No need to have $(LIBBPF) (from
$^) on that command, let's do with "$(OBJS) $(LIBS)" (but move $(LIBBPF)
_before_ the -l flags in $(LIBS)).

Subject: libbpf: add flags to umem config

This patch adds a 'flags' field to the umem_config and umem_reg structs.
This will allow for more options to be added for configuring umems.

The first use for the flags field is to add a flag for unaligned chunks
mode. These flags can either be user-provided or filled with a default.

Since we change the size of the xsk_umem_config struct, we need to version
the ABI. This patch includes the ABI versioning for xsk_umem__create. The
Makefile was also updated to handle multiple function versions in
check-abi.

Subject: tools/power x86_energy_perf_policy: Fix "uninitialized variable"
 warnings at -O2

x86_energy_perf_policy first uses __get_cpuid() to check the maximum
CPUID level and exits if it is too low.  It then assumes that later
calls will succeed (which I think is architecturally guaranteed).  It
also assumes that CPUID works at all (which is not guaranteed on
x86_32).

If optimisations are enabled, gcc warns about potentially
uninitialized variables.  Fix this by adding an exit-on-error after
every call to __get_cpuid() instead of just checking the maximum
level.

Subject: tools/power/x86: Enable compiler optimisations and Fortify by default

Compiling without optimisations is silly, especially since some
warnings depend on the optimiser.  Use -O2.

Fortify adds warnings for unchecked I/O (among other things), which
seems to be a good idea for user-space code.  Enable that too.

Subject: tools/power x86_energy_perf_policy: Fix argument parsing

The -w argument in x86_energy_perf_policy currently triggers an
unconditional segfault.

This is because the argument string reads: "+a:c:dD:E:e:f:m:M:rt:u:vw" and
yet the argument handler expects an argument.

When parse_optarg_string is called with a null argument, we then proceed to
crash in strncmp, not horribly friendly.

The man page describes -w as taking an argument, the long form
(--hwp-window) is correctly marked as taking a required argument, and the
code expects it.

As such, this patch simply marks the short form (-w) as requiring an
argument.

Subject: tools/power turbostat: Make interval calculation per thread to reduce
 jitter

Turbostat currently normalizes TSC and other values by dividing by an
interval. This interval is the delta between the start of one global
(all counters on all CPUs) sampling and the start of another. However,
this introduces a lot of jitter into the data.

In order to reduce jitter, the interval calculation should be based on
timestamps taken per thread and close to the start of the thread's
sampling.

Define a per thread time value to hold the delta between samples taken
on the thread.

Use the timestamp taken at the beginning of sampling to calculate the
delta.

Move the thread's beginning timestamp to after the CPU migration to
avoid jitter due to the migration.

Use the global time delta for the average time delta.

Subject: tools/power turbostat: fix buffer overrun

turbostat could be terminated by general protection fault on some latest
hardwares which (for example) support 9 levels of C-states and show 18
"tADDED" lines. That bloats the total output and finally causes buffer
overrun.  So let's extend the buffer to avoid this.

Subject: tools/power turbostat: read from pipes too

Commit '47936f944e78 tools/power turbostat: fix printing on input' make
a valid fix, but it completely disabled piped stdin support, which is
a valuable use-case. Indeed, if stdin is a pipe, turbostat won't read
anything from it, so it becomes impossible to get turbostat output at
user-defined moments, instead of the regular intervals.

There is no reason why this should works for terminals, but not for
pipes. This patch improves the situation. Instead of ignoring pipes, we
read data from them but gracefully handle the EOF case.

Subject: tools/power turbostat: do not enforce 1ms

Turbostat works by taking a snapshot of counters, sleeping, taking another
snapshot, calculating deltas, and printing out the table.

The sleep time is controlled via -i option or by user sending a signal or a
character to stdin. In the latter case, turbostat always adds 1 ms
sleep before it reads the counters, in order to avoid larger imprecisions
in the results in prints.

While the 1 ms delay may be a good idea for a "dumb" user, it is a
problem for an "aware" user. I do thousands and thousands of measurements
over a short period of time (like 2ms), and turbostat unconditionally adds
a 1ms to my interval, so I cannot get what I really need.

This patch removes the unconditional 1ms sleep. This is an expert user
tool, after all, and non-experts will unlikely ever use it in the non-fixed
interval mode anyway, so I think it is OK to remove the 1ms delay.

Subject: tools/power turbostat: Fix CPU%C1 display value

In some case C1% will be wrong value, when platform doesn't have MSR for
C1 residency.

For example:
Core    CPU     CPU%c1
-       -       100.00
0       0       100.00
0       2       100.00
1       1       100.00
1       3       100.00

But adding Busy% will fix this
Core    CPU     Busy%   CPU%c1
-       -       99.77   0.23
0       0       99.77   0.23
0       2       99.77   0.23
1       1       99.77   0.23
1       3       99.77   0.23

This issue can be reproduced on most of the recent systems including
Broadwell, Skylake and later.

This is because if we don't select Busy% or Avg_MHz or Bzy_MHz then
mperf value will not be read from MSR, so it will be 0. But this
is required for C1% calculation when MSR for C1 residency is not present.
Same is true for C3, C6 and C7 column selection.

So add another define DO_BIC_READ(), which doesn't depend on user
column selection and use for mperf, C3, C6 and C7 related counters.
So when there is no platform support for C1 residency counters,
we still read these counters, if the CPU has support and user selected
display of CPU%c1.

Subject: tools/power turbostat: Fix caller parameter of get_tdp_amd()

Commit 9392bd98bba760be96ee ("tools/power turbostat: Add support for AMD
Fam 17h (Zen) RAPL") add a function get_tdp_amd(), the parameter is CPU
family. But the rapl_probe_amd() function use wrong model parameter.
Fix the wrong caller parameter of get_tdp_amd() to use family.

Subject: tools/power turbostat: Add support for Hygon Fam 18h (Dhyana) RAPL

Commit 9392bd98bba760be96ee ("tools/power turbostat: Add support for AMD
Fam 17h (Zen) RAPL") and the commit 3316f99a9f1b68c578c5 ("tools/power
turbostat: Also read package power on AMD F17h (Zen)") add AMD Fam 17h
RAPL support.

Hygon Family 18h(Dhyana) support RAPL in bit 14 of CPUID 0x80000007 EDX,
and has MSRs RAPL_PWR_UNIT/CORE_ENERGY_STAT/PKG_ENERGY_STAT. So add Hygon
Dhyana Family 18h support for RAPL.

Already tested on Hygon multi-node systems and it shows correct per-core
energy usage and the total package power.

Subject: perf debug: Remove needless include directives from debug.h

All we need there is a forward declaration for 'union perf_event', so
remove it from there and add missing header directives in places using
things from this indirect include.

From 38847db9740a984e8538ce2573cbc0fc7edf22b3 Mon Sep 17 00:00:00 2001
From: Tzvetomir Stoyanov <tstoyanov@vmware.com>
Date: Mon, 5 Aug 2019 16:43:13 -0400
Subject: libtraceevent, perf tools: Changes in tep_print_event_* APIs

Libtraceevent APIs for printing various trace events information are
complicated, there are complex extra parameters. To control the way
event information is printed, the user should call a set of functions in
a specific sequence.

These APIs are reimplemented to provide a more simple interface for
printing event information.

Removed APIs:

 	tep_print_event_task()
	tep_print_event_time()
	tep_print_event_data()
	tep_event_info()
	tep_is_latency_format()
	tep_set_latency_format()
	tep_data_latency_format()
	tep_set_print_raw()

A new API for printing event information is introduced:
   void tep_print_event(struct tep_handle *tep, struct trace_seq *s,
		        struct tep_record *record, const char *fmt, ...);
where "fmt" is a printf-like format string, followed by the event
fields to be printed. Supported fields:
 TEP_PRINT_PID, "%d" - event PID
 TEP_PRINT_CPU, "%d" - event CPU
 TEP_PRINT_COMM, "%s" - event command string
 TEP_PRINT_NAME, "%s" - event name
 TEP_PRINT_LATENCY, "%s" - event latency
 TEP_PRINT_TIME, %d - event time stamp. A divisor and precision
   can be specified as part of this format string:
   "%precision.divisord". Example:
   "%3.1000d" - divide the time by 1000 and print the first 3 digits
   before the dot. Thus, the time stamp "123456000" will be printed as
   "123.456"
 TEP_PRINT_INFO, "%s" - event information.
 TEP_PRINT_INFO_RAW, "%s" - event information, in raw format.

Example:
  tep_print_event(tep, s, record, "%16s-%-5d [%03d] %s %6.1000d %s %s",
		  TEP_PRINT_COMM, TEP_PRINT_PID, TEP_PRINT_CPU,
		  TEP_PRINT_LATENCY, TEP_PRINT_TIME, TEP_PRINT_NAME, TEP_PRINT_INFO);
Output:
	ls-11314 [005] d.h. 185207.366383 function __wake_up

Subject: libtraceevent: Remove tep_register_trace_clock()

The tep_register_trace_clock() API is used to instruct the traceevent
library how to print the event time stamps. As event print interface if
redesigned, this API is not needed any more.  The new event print API is
flexible and the user can specify how the time stamps are printed.

From 4a3cec84949d14dc3ef7fb8a51b8949af93cac13 Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Date: Fri, 30 Aug 2019 11:11:01 -0300
Subject: perf dsos: Move the dsos struct and its methods to separate source
 files

So that we can reduce the header dependency tree further, in the process
noticed that lots of places were getting even things like build-id
routines and 'struct perf_tool' definition indirectly, so fix all those
too.

Subject: perf hist: Remove needless ui/progress.h from hist.h

We only need a forward declaration, add it and fixup all the files that
need ui_progress definitions but were wrongly getting it from hist.h.

Subject: perf tools: Move 'struct events_stats' and prototypes to separate
 header

This will allow us to untangle the header dependency a bit more, as some
places will not need event.h anymore.

Subject: perf tools: Remove needless sort.h include directives

Now that sort.h isn't included by any other header, we can check where
it is really needed, i.e. we can remove it and be sure that it isn't
being obtained indirectly.

Subject: perf tools: Remove needless evlist.h include directives

Remove the last unneeded use of cache.h in a header, we can check where
it is really needed, i.e. we can remove it and be sure that it isn't
being obtained indirectly.

This is an old file, used by now incorrectly in many places, so it was
providing includes needed indirectly, fixup this fallout.

From f2a39fe84901df2b3d1bec3459b65cee3e8db57c Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Date: Fri, 30 Aug 2019 14:45:20 -0300
Subject: perf auxtrace: Uninline functions that touch perf_session

So that we don't carry the session.h include directive in auxtrace.h,
which in turn opens a can of worms of files that were getting all sorts
of things via that include, fix them all.

From d3300a3c4e76ccecf4daa889327e340a870c550b Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Date: Fri, 30 Aug 2019 15:09:54 -0300
Subject: perf symbols: Move mem_info and branch_info out of symbol.h

The mem_info struct goes to mem-events.h and branch_info goes to
branch.h, where they belong, this way we can remove several headers from
symbols.h and trim the include dependency tree more.

Subject: perf pmu: Change convert_scale from static to global

The function convert_scale() can be used to convert string to unit and
scale. For example,

  s = "6000000000ns";
  convert_scale(s, &unit, &scale);

unit = "ns", scale = 6000000000.

Currently this function is static. This patch renames the function to
perf_pmu__convert_scale and changes the function to global.  No
functional change.

Subject: perf metricgroup: Scale the metric result

Some metrics define the scale unit, such as

    {
        "BriefDescription": "Intel Optane DC persistent memory read latency (ns). Derived from unc_m_pmm_rpq_occupancy.all",
        "Counter": "0,1,2,3",
        "EventCode": "0xE0",
        "EventName": "UNC_M_PMM_READ_LATENCY",
        "MetricExpr": "UNC_M_PMM_RPQ_OCCUPANCY.ALL / UNC_M_PMM_RPQ_INSERTS / UNC_M_CLOCKTICKS",
        "MetricName": "UNC_M_PMM_READ_LATENCY",
        "PerPkg": "1",
        "ScaleUnit": "6000000000ns",
        "UMask": "0x1",
        "Unit": "iMC"
    },

For above example, the ratio should be,

ratio = (UNC_M_PMM_RPQ_OCCUPANCY.ALL / UNC_M_PMM_RPQ_INSERTS / UNC_M_CLOCKTICKS) * 6000000000

But in current code, the ratio is not scaled ( * 6000000000)

With this patch, the ratio is scaled and the unit (ns) is printed.

For example,
  #    219.4 ns  UNC_M_PMM_READ_LATENCY

Subject: perf metricgroup: Support multiple events for metricgroup

Some uncore metrics don't work as expected. For example, on
cascadelakex:

  root@lkp-csl-2sp2:~# perf stat -M UNC_M_PMM_BANDWIDTH.TOTAL -a -- sleep 1

   Performance counter stats for 'system wide':

           1841092      unc_m_pmm_rpq_inserts
           3680816      unc_m_pmm_wpq_inserts

       1.001775055 seconds time elapsed

  root@lkp-csl-2sp2:~# perf stat -M UNC_M_PMM_READ_LATENCY -a -- sleep 1

   Performance counter stats for 'system wide':

         860649746      unc_m_pmm_rpq_occupancy.all
           1840557      unc_m_pmm_rpq_inserts
       12790627455      unc_m_clockticks

       1.001773348 seconds time elapsed

No metrics 'UNC_M_PMM_BANDWIDTH.TOTAL' or 'UNC_M_PMM_READ_LATENCY' are
reported.

The issue is, the case of an alias expanding to mulitple events is not
supported, typically the uncore events.  (see comments in
find_evsel_group()).

For UNC_M_PMM_BANDWIDTH.TOTAL in above example, the expanded event group
is '{unc_m_pmm_rpq_inserts,unc_m_pmm_wpq_inserts}:W', but the actual
events passed to find_evsel_group are:

  unc_m_pmm_rpq_inserts
  unc_m_pmm_rpq_inserts
  unc_m_pmm_rpq_inserts
  unc_m_pmm_rpq_inserts
  unc_m_pmm_rpq_inserts
  unc_m_pmm_rpq_inserts
  unc_m_pmm_wpq_inserts
  unc_m_pmm_wpq_inserts
  unc_m_pmm_wpq_inserts
  unc_m_pmm_wpq_inserts
  unc_m_pmm_wpq_inserts
  unc_m_pmm_wpq_inserts

For this multiple events case, it's not supported well.

This patch introduces a new field 'metric_leader' in struct evsel. The
first event is considered as a metric leader. For the rest of same
events, they point to the first event via it's metric_leader field in
struct evsel.

This design is for adding the counting results of all same events to the
first event in group (the metric_leader).

With this patch,

  root@lkp-csl-2sp2:~# perf stat -M UNC_M_PMM_BANDWIDTH.TOTAL -a -- sleep 1

   Performance counter stats for 'system wide':

           1842108      unc_m_pmm_rpq_inserts     #    337.2 MB/sec  UNC_M_PMM_BANDWIDTH.TOTAL
           3682209      unc_m_pmm_wpq_inserts

       1.001819706 seconds time elapsed

  root@lkp-csl-2sp2:~# perf stat -M UNC_M_PMM_READ_LATENCY -a -- sleep 1

   Performance counter stats for 'system wide':

         861970685      unc_m_pmm_rpq_occupancy.all #    219.4 ns  UNC_M_PMM_READ_LATENCY
           1842772      unc_m_pmm_rpq_inserts
       12790196356      unc_m_clockticks

       1.001749103 seconds time elapsed

Now we can see the correct metrics 'UNC_M_PMM_BANDWIDTH.TOTAL' and
'UNC_M_PMM_READ_LATENCY'.

Subject: objtool: Move x86 insn decoder to a common location

The kernel tree has three identical copies of the x86 instruction
decoder.  Two of them are in the tools subdir.

The tools subdir is supposed to be completely standalone and separate
from the kernel.  So having at least one copy of the kernel decoder in
the tools subdir is unavoidable.  However, we don't need *two* of them.

Move objtool's copy of the decoder to a shared location, so that perf
will also be able to use it.

Subject: perf: Update .gitignore file

After a "make tools/perf", git reports the following untracked files:

  tools/perf/feature/
  tools/perf/fixdep
  tools/perf/libtraceevent-dynamic-list

Add these generated files to perf's .gitignore file.

Subject: perf intel-pt: Remove inat.c from build dependency list

intel-pt-insn-decoder.c includes inat.c directly, so it already has an
implicit dependency on inat.c.  The Build file dependency is redundant.

Subject: perf intel-pt: Use shared x86 insn decoder

Now that there's a common version of the decoder for all tools, use it
instead of the local copy.

Also use perf's check-headers.sh script to diff the decoder files to
make sure they remain in sync with the kernel version.  Objtool has a
similar check.

Committer notes:

Had to keep this all pointing explicitely to x86 headers/files, i.e.
instead of asm/isnn.h we had to use ../include/asm/insn.h when the files
were in differemt dirs, or just replace "<asm/foo.h>" with "foo.h".

This way we continue to be able to process perf.data files with Intel PT
traces in distros other than x86.

Also fixed up the awk script paths to use $(srcdir)/tools/arch instead
or relative directories so that we keep detached tarballs (make help |
grep perf) working.

For now the include lines in these headers are being ignored so as not
to flag false reports of kernel/tools out of sync.

Subject: perf build: Ignore intentional differences for the x86 insn decoder

Since we need to build this in !x86, we need to explicitely use the x86
files, not things like asm/insn.h, so we intentionally differ from the
master copy in the kernel sources, add -I diff directives to ignore just
these differences when checking for drift.

Subject: objtool: Update sync-check.sh from perf's check-headers.sh

To allow using the -I trick that will be needed for checking the x86
insn decoder files.

Without the specific -I lines we still get the same warnings as before:

  $ make -C tools/objtool/ clean ; make -C tools/objtool/
  make: Entering directory '/home/acme/git/perf/tools/objtool'
    CLEAN    objtool

The next patch will add the -I lines for those files.

Subject: objtool: Ignore intentional differences for the x86 insn decoder

Since we need to build this in !x86, we need to explicitely use the x86
files, not things like asm/insn.h, so we intentionally differ from the
master copy in the kernel sources, add -I diff directives to ignore just
these differences when checking for drift.

Subject: tc-testing: don't hardcode 'ip' in nsPlugin.py

the following tdc test fails on Fedora:

 # ./tdc.py -e 2638
  -- ns/SubPlugin.__init__
 Test 2638: Add matchall and try to get it
 -----> prepare stage *** Could not execute: "$TC qdisc add dev $DEV1 clsact"
 -----> prepare stage *** Error message: "/bin/sh: ip: command not found"
 returncode 127; expected [0]
 -----> prepare stage *** Aborting test run.

Let nsPlugin.py use the 'IP' variable introduced with commit 92c1a19e2fb9
("tc-tests: added path to ip command in tdc"), so that the path to 'ip' is
correctly resolved to the value we have in tdc_config.py.

 # ./tdc.py -e 2638
  -- ns/SubPlugin.__init__
 Test 2638: Add matchall and try to get it
 All test results:
 1..1
 ok 1 2638 - Add matchall and try to get it

Subject: selftests/bpf: test_progs: fix verbose mode garbage

fseeko(.., 0, SEEK_SET) on a memstream just puts the buffer pointer
to the beginning so when we call fflush on it we get some garbage
log data from the previous test. Let's manually set terminating
byte to zero at the reported buffer size.

To show the issue consider the following snippet:

	stream = open_memstream (&buf, &len);

	fprintf(stream, "aaa");
	fflush(stream);
	printf("buf=%s, len=%zu\n", buf, len);
	fseeko(stream, 0, SEEK_SET);

	fprintf(stream, "b");
	fflush(stream);
	printf("buf=%s, len=%zu\n", buf, len);

Output:

	buf=aaa, len=3
	buf=baa, len=1

Subject: selftests/bpf: introduce bpf_cpu_to_be64 and bpf_be64_to_cpu

test_lwt_seg6local and test_seg6_loop use custom 64-bit endianness
conversion macros. Centralize their definitions in bpf_endian.h in order
to reduce code duplication. This will also be useful when bpf_endian.h
is promoted to an offical libbpf header.

Subject: selftests/bpf: fix "ctx:write sysctl:write read ok" on s390

"ctx:write sysctl:write read ok" fails on s390 because it reads the
first byte of an int assuming it's the least-significant one, which
is not the case on big-endian arches. Since we are not testing narrow
accesses here (there is e.g. "ctx:file_pos sysctl:read read ok narrow"
for that), simply read the whole int.

Subject: selftests/bpf: improve unexpected success reporting in test_syctl

When tests fail because sysctl() unexpectedly succeeds, they print an
inappropriate "Unexpected failure" message and a random errno. Zero
out errno before calling sysctl() and replace the message with
"Unexpected success".

Subject: selftests/bpf: fix endianness issues in test_sysctl

A lot of test_sysctl sub-tests fail due to handling strings as a bunch
of immediate values in a little-endian-specific manner.

Fix by wrapping all immediates in bpf_ntohl and the new bpf_be64_to_cpu.

fixup_sysctl_value() dynamically writes an immediate, and thus should be
endianness-aware.  Implement this by simply memcpy()ing the raw
user-provided value, since testcase endianness and bpf program
endianness match.

Subject: KVM: selftests: Test invalid bits in kvm_valid_regs and
 kvm_dirty_regs on s390x

Now that we disallow invalid bits in kvm_valid_regs and kvm_dirty_regs
on s390x, too, we should also check this condition in the selftests.
The code has been taken from the x86-version of the sync_regs_test.

Subject: selftests/powerpc: Add basic EEH selftest

Use the new eeh_dev_check and eeh_dev_break interfaces to test EEH
recovery.  Historically this has been done manually using platform specific
EEH error injection facilities (e.g. via RTAS). However, documentation on
how to use these facilities is haphazard at best and non-existent at worst
so it's hard to develop a cross-platform test.

The new debugfs interfaces allow the kernel to handle the platform specific
details so we can write a more generic set of sets. This patch adds the
most basic of recovery tests where:

a) Errors are injected and recovered from sequentially,
b) Errors are not injected into PCI-PCI bridges, such as PCIe switches.
c) Errors are only injected into device function zero.
d) No errors are injected into Virtual Functions.

a), b) and c) are largely due to limitations of Linux's EEH support.  EEH
recovery is serialised in the EEH recovery thread which forces a).
Similarly, multi-function PCI devices are almost always grouped into the
same PE so injecting an error on one function exercises the same code
paths. c) is because we currently more or less ignore PCI bridges during
recovery and assume that the recovered topology will be the same as the
original.

d) is due to the limits of the eeh_dev_break interface. With the current
implementation we can't inject an error into a specific VF without
potentially causing additional errors on other VFs. Due to the serialised
recovery process we might end up timing out waiting for another function to
recover before the function of interest is recovered. The platform specific
error injection facilities are finer-grained and allow this capability, but
doing that requires working out how to use those facilities first.

Basicly, it's better than nothing and it's a base to build on.

From 91bfb564853f4aaa0487a2b5e9c6ecd400768abd Mon Sep 17 00:00:00 2001
From: David Ahern <dsahern@gmail.com>
Date: Tue, 3 Sep 2019 15:22:13 -0700
Subject: selftest: A few cleanups for fib_nexthops.sh

Cleanups of the tests in fib_nexthops.sh
1. Several tests noted unexpected route output, but the
   discrepancy was not showing in the summary output and
   overlooked in the verbose output. Add a WARNING message
   to the summary output to make it clear a test is not showing
   expected output.

2. Several check_* calls are missing extra data like scope and metric
   causing mismatches when the nexthops or routes are correct - some of
   them are a side effect of the evolving iproute2 command. Update the
   data to the expected output.

3. Several check_routes are checking for the wrong nexthop data,
   most likely a copy-paste-update error.

4. A couple of tests were re-using a nexthop id that already existed.
   Fix those to use a new id.

Fixes: 6345266a9989 ("selftests: Add test cases for nexthop objects")

From 310f4204eeb6053e35c277a23d9c179e8e32322e Mon Sep 17 00:00:00 2001
From: Alexei Starovoitov <ast@kernel.org>
Date: Tue, 3 Sep 2019 15:51:33 -0700
Subject: selftests/bpf: precision tracking tests

Add two tests to check that stack slot marking during backtracking
doesn't trigger 'spi > allocated_stack' warning.
One test is using BPF_ST insn. Another is using BPF_STX.

Subject: selftests/bpf: test_progs: add test__join_cgroup helper

test__join_cgroup() combines the following operations that usually
go hand in hand and returns cgroup fd:

  * setup cgroup environment (make sure cgroupfs is mounted)
  * mkdir cgroup
  * join cgroup

It also marks a test as a "cgroup cleanup needed" and removes cgroup
state after the test is done.

Subject: selftests/bpf: test_progs: convert test_sockopt_inherit

Move the files, adjust includes, remove entry from Makefile & .gitignore

I also added pthread_cond_wait for the server thread startup. We don't
want to connect to the server that's not yet up (for some reason
this existing race is now more prominent with test_progs).

Subject: tools/power/x86/intel-speed-select: Fix a read overflow in
 isst_set_tdp_level_msr()

The isst_send_msr_command() function will read 8 bytes but we are
passing an address to an int (4 bytes) so it results in a read overflow.

Subject: tools/power/x86/intel-speed-select: Fix cpu-count output

I have a system with 28 threads/socket but intel-speed-select reports
a cpu-count of 29.

Fix an off-by-one error in the cpu_count() function.

Subject: tools/power/x86/intel-speed-select: Simplify output for turbo-freq
 and base-freq

The current output of 'intel-speed-select -c 53 perf-profile info -l 0'
shows

        speed-select-turbo-freq-support:1
        speed-select-base-freq-support:1
        speed-select-base-freq-enabled:0
        speed-select-turbo-freq-enabled:0

Simplify the output to single lines displaying status of disabled,
enabled, and unsupported.

The intel-speed-select tool currently outputs the turbo ratio for every
bucket.  Make the output more user-friendly by changing the output to the
maximum turbo frequency.

Subject: tools/power/x86/intel-speed-select: Output human readable CPU list

The intel-speed-select tool currently only outputs a hexidecimal CPU mask,
which requires translation for use with kernel parameters such as
isolcpus.

Along with the CPU mask, output a human readable CPU list.

Command output has confusing data, returning "0" on success.  For example

|# ./intel-speed-select -c 14 turbo-freq enable
Intel(R) Speed Select Technology
Executing on CPU model:106[0x6a]
 package-1
   die-0
     cpu-14
       turbo-freq
         enable:0

To avoid confusion change the command output to 'success' or 'failed'.

v2: Remove help output line.

Subject: tools/power/x86/intel-speed-select: Fix memory leak

cpumasks are allocated by calling the alloc_cpu_mask() function and are
never free'd.  They should be free'd after the commands have run.

Fix the memory leaks by calling free_cpu_set().

Subject: objtool: Clobber user CFLAGS variable

If the build user has the CFLAGS variable set in their environment,
objtool blindly appends to it, which can cause unexpected behavior.

Clobber CFLAGS to ensure consistent objtool compilation behavior.

Subject: perf python: Add missing python/perf.so dependency for libperf

The python/perf.so compilation needs libperf ready, otherwise it fails:

  $ make python/perf.so JOBS=1
    BUILD:   Doing 'make -j1' parallel build
    GEN      python/perf.so
  gcc: error: /home/jolsa/kernel/linux-perf/tools/perf/lib/libperf.a: No such file or directory

Fixing this with by adding libperf dependency.

Subject: iocost_monitor: Always use strings for json values

Json has limited accuracy for numbers and can silently truncate 64bit
values, which can be extremely confusing.  Let's consistently use
string encapsulated values for json output.

While at it, convert an unnecesary f-string to str().

Subject: iocost_monitor: Report more info with higher accuracy

When outputting json:

* Don't truncate numbers.

* Report address of iocg to ease drilling down further.

When outputting table:

* Use math.ceil() for delay_ms so that small delays don't read as 0.

Subject: kselftests: cgroup: add freezer mkdir test

Add a new cgroup freezer selftest, which checks that if a cgroup is
frozen, their new child cgroups will properly inherit the frozen
state.

It creates a parent cgroup, freezes it, creates a child cgroup
and populates it with a dummy process. Then it checks that both
parent and child cgroup are frozen.

Subject: selftests/bpf: add bpf-gcc support

Now that binutils and gcc support for BPF is upstream, make use of it in
BPF selftests using alu32-like approach. Share as much as possible of
CFLAGS calculation with clang.

Fixes only obvious issues, leaving more complex ones for later:
- Use gcc-provided bpf-helpers.h instead of manually defining the
  helpers, change bpf_helpers.h include guard to avoid conflict.
- Include <linux/stddef.h> for __always_inline.
- Add $(OUTPUT)/../usr/include to include path in order to use local
  kernel headers instead of system kernel headers when building with O=.

In order to activate the bpf-gcc support, one needs to configure
binutils and gcc with --target=bpf and make them available in $PATH. In
particular, gcc must be installed as `bpf-gcc`, which is the default.

Right now with binutils 25a2915e8dba and gcc r275589 only a handful of
tests work:

	# ./test_progs_bpf_gcc
	# Summary: 7/39 PASSED, 1 SKIPPED, 98 FAILED

The reason for those failures are as follows:

- Build errors:
  - `error: too many function arguments for eBPF` for __always_inline
    functions read_str_var and read_map_var - must be inlining issue,
    and for process_l3_headers_v6, which relies on optimizing away
    function arguments.

Subject: bpf: fix accessing bpf_sysctl.file_pos on s390

"ctx:file_pos sysctl:read write ok" fails on s390 with "Read value  !=
nux". This is because verifier rewrites a complete 32-bit
bpf_sysctl.file_pos update to a partial update of the first 32 bits of
64-bit *bpf_sysctl_kern.ppos, which is not correct on big-endian
systems.

Fix by using an offset on big-endian systems.

Ditto for bpf_sysctl.file_pos reads. Currently the test does not detect
a problem there, since it expects to see 0, which it gets with high
probability in error cases, so change it to seek to offset 3 and expect
3 in bpf_sysctl.file_pos.

Fixes: e1550bfe0de4 ("bpf: Add file_pos field to bpf_sysctl ctx")

Subject: selftests, arm64: add kernel headers path for tags_test

tags_test.c relies on PR_SET_TAGGED_ADDR_CTRL/PR_TAGGED_ADDR_ENABLE being
present in system headers. When this is not the case the build of this
test fails with undeclared identifier errors.

Fix by providing the path to the KSFT installed kernel headers in CFLAGS.

Subject: selftests/ftrace: Select an existing function in kprobe_eventname
 test

Running the ftrace selftests on the latest kernel caused the
kprobe_eventname test to fail. It was due to the test that searches for
a function with at "dot" in the name and adding a probe to that.
Unfortunately, for this test, it picked:

 optimize_nops.isra.2.cold.4

Which happens to be marked as "__init", which means it no longer exists
in the kernel! (kallsyms keeps those function names around for tracing
purposes)

As only functions that still exist are in the
available_filter_functions file, as they are removed when the functions
are freed at boot or module exit, have the test search for a function
with ".isra." in the name as well as being in the
available_filter_functions (if the file exists).

 count

If the CPU package has the less logical CPU than topo_max_cpus, but un-present
CPU's punit_cpu_core will be initiated to 0 and they will be count to core 0

Like below, there are only 10 high priority cores (20 logical CPUs) in the CPU
package, but it count to 27 logic CPUs.

./intel-speed-select base-freq info -l 0 | grep mask
        high-priority-cpu-mask:7f000179,f000179f

With the fix patch:
./intel-speed-select base-freq info -l 0

the result field is changed to string interpreting every non zero
value as errors. But these commands display on zero (>0) result.
For example before this commit the display was:

package-1
  die-0
    cpu-14
        get-config-levels:4

Here the get-config-levels is interpreted as error and displayed
as error with the above commit:

package-1
  die-0
    cpu-14
        get-config-levels:failed(error 4)

Fix this issue by not using isst_display_result() to display such results,
but define a new function which formats this data and prints.

Subject: libbpf: Remove getsockopt() check for XDP_OPTIONS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The xsk_socket__create() function fails and returns an error if it cannot
get the XDP_OPTIONS through getsockopt(). However, support for XDP_OPTIONS
was not added until kernel 5.3, so this means that creating XSK sockets
always fails on older kernels.

Since the option is just used to set the zero-copy flag in the xsk struct,
and that flag is not really used for anything yet, just remove the
getsockopt() call until a proper use for it is introduced.

Thanks to Jiri Olsa for fixing up my initial stab at this, I forgot how
Makefiles are picky about spaces versus tabs.

From 8fcbeae44fde9756036147664d1e74fab7c9902c Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Date: Tue, 3 Sep 2019 09:47:53 -0300
Subject: perf tools: Remove needless builtin.h include directives

Now that builtin.h isn't included by any other header, we can check
where it is really needed, i.e. we can remove it and be sure that it
isn't being obtained indirectly.

Subject: perf debug: No need to include ui/util.h

Nothing from that file is used in util/debug.h, it is only needed in
some places that get it indirectly via including util/debug.h, remove
that entanglement.

Subject: perf tools: Remove debug.h from places where it is not needed

Pruning a bit more the includes dependency tree. Building this thing on
lots of containers takes time, we better reduce the time per build, each
container is doing 6 builds when clang and clang-devel are available,
and the plan is to do a 'make -C tools/perf build-test' that have many
more.

Also helps when doing normal development, as touching some random file
will have a much reduced chance of triggering lots of rebuilds.

Subject: perf event: Move perf_event__synthesize* to event.h

Where is the perf_event__handler_t typedef they need, which was the only
reason for header.h to be including event.h, untangle that.

Subject: perf stat: Move perf_stat_synthesize_config() to event.h

Together with the other synthsizers, and rename it to
perf_event__synthesize_stat_events().

This allows us to stop including event.h in util/stat.h.

Subject: perf tools: Move event synthesizing routines to separate header

Those are the only routines using the perf_event__handler_t typedef and
are all related, so move to a separate header to reduce the header
dependency tree, lots of places were getting event.h and even stdio.h,
limits.h indirectly, so fix those as well.

Subject: perf memswap: Adopt 'struct u64_swap' from evsel.h

As it is not used in evsel.h and is a memory swap struct, so fits better
in memswap.h.

Subject: perf tools: Move event synthesizing routines to separate .c file

For better grouping, in time we may end up making most of these static,
i.e. generalizing the 'perf record' synthesizing code so that based on
the target it can do the right thing and call the needed synthesizers.

Subject: perf stat: Reset previous counts on repeat with interval

When using 'perf stat' with repeat and interval option, it shows wrong
values for events.

The wrong values will be shown for the first interval on the second and
subsequent repetitions.

Without the fix:

  # perf stat -r 3 -I 2000 -e faults -e sched:sched_switch -a sleep 5

prev_raw_counts is allocated when using intervals. This is used when
calculating the difference in the counts of events when using interval.

The current counts are stored in prev_raw_counts to calculate the
differences in the next iteration.

On the first interval of the second and subsequent repetitions,
prev_raw_counts would be the values stored in the last interval of the
previous repetitions, while the current counts will only be for the
first interval of the current repetition.

Hence there is a possibility of events showing up as big number.

Fix this by resetting prev_raw_counts whenever perf stat repeats the
command.

  # perf stat -r 3 -I 2000 -e faults -e sched:sched_switch -a sleep 5

Committer notes:

This was broken since the cset introducing the --interval feature, i.e.
--repeat + --interval wasn't tested at that point, add the Fixes tag so
that automatic scripts can pick this up.

Subject: perf stat: Fix a segmentation fault when using repeat forever

Observe a segmentation fault when 'perf stat' is asked to repeat forever
with the interval option.

Without fix:

  # perf stat -r 0 -I 5000 -e cycles -a sleep 10
  #           time             counts unit events
       5.000211692  3,13,89,82,34,157      cycles
      10.000380119  1,53,98,52,22,294      cycles
      10.040467280       17,16,79,265      cycles
  Segmentation fault

This problem was only observed when we use forever option aka -r 0 and
works with limited repeats. Calling print_counter with ts being set to
NULL, is not a correct option when interval is set. Hence avoid
print_counter(NULL,..)  if interval is set.

With fix:

  # perf stat -r 0 -I 5000 -e cycles -a sleep 10
   #           time             counts unit events
       5.019866622  3,15,14,43,08,697      cycles

Move kvm-stat header file to the common include section, and make the
definitions in the header file under the conditional inclusion `#ifdef
HAVE_KVM_STAT_SUPPORT`.

This helps to define other 'perf kvm' related function prototypes in
kvm-stat header file, which may not need kvm-stat support.

Subject: perf kvm: Add arch neutral function to choose event for perf kvm
 record

'perf kvm record' uses 'cycles'(if the user did not specify any event)
as the default event to profile the guest.

This will not provide any proper samples from the guest incase of
powerpc architecture, since in powerpc the PMUs are controlled by the
guest rather than the host.

Patch adds a function to pick an arch specific event for 'perf kvm
record', instead of selecting 'cycles' as a default event for all
architectures.

For powerpc this function checks for any user specified event, and if
there isn't any it returns invalid instead of proceeding with 'cycles'
event.

Being able to pass something like:

  # perf record -e syscalls:sys_enter_prctl --filter="option=*TAGGED_ADDR*"

Should be easy enough, first using tracepoint filters, then via the
augmented_raw_syscalls.c BPF method.

This addresses this perf build warning:

Subject: perf probe: Skip same probe address for a given line

Fix to skip making a same probe address on given line.

Since a DWARF line info contains several entries for one line with
different column, perf probe will make a different probe on same address
if user specifies a probe point by "function:line" or "file:line".

e.g.
 $ perf probe -D kernel_read:8
 p:probe/kernel_read_L8 kernel_read+39
 p:probe/kernel_read_L8_1 kernel_read+39

This skips such duplicated probe addresses.

Subject: perf probe: Fix to clear tev->nargs in clear_probe_trace_event()

Since add_probe_trace_event() can reuse tf->tevs[i] after calling
clear_probe_trace_event(), this can make perf-probe crash if the 1st
attempt of probe event finding fails to find an event argument, and the
2nd attempt fails to find probe point.

E.g.
  $ perf probe -D "task_pid_nr tsk"
  Failed to find 'tsk' in this function.
  Failed to get entry address of warn_bad_vsyscall
  Segmentation fault (core dumped)

Committer testing:

After the patch:

  $ perf probe -D "task_pid_nr tsk"
  Failed to find 'tsk' in this function.
  Failed to get entry address of warn_bad_vsyscall
  Failed to get entry address of signal_fault
  Failed to get entry address of show_signal
  Failed to get entry address of umip_printk
  Failed to get entry address of __bad_area_nosemaphore
  <SNIP>
  Failed to get entry address of sock_set_timeout
  Failed to get entry address of tcp_recvmsg
  Probe point 'task_pid_nr' not found.
    Error: Failed to add events.

Subject: perf session: Return error code for perf_session__new() function on
 failure

This patch is to return error code of perf_new_session function on
failure instead of NULL.

Test Results:

Before Fix:

  $ perf c2c report -input
  failed to open nput: No such file or directory

  $ echo $?
  0
  $

After Fix:

  $ perf c2c report -input
  failed to open nput: No such file or directory

  $ echo $?
  254
  $

Committer notes:

Fix 'perf tests topology' case, where we use that TEST_ASSERT_VAL(...,
session), i.e. we need to pass zero in case of failure, which was the
case before when NULL was returned by perf_session__new() for failure,
but now we need to negate the result of IS_ERR(session) to respect that
TEST_ASSERT_VAL) expectation of zero meaning failure.

Subject: perf record: Fix priv level with branch sampling for paranoid=2

Now that the default perf_events paranoid level is set to 2, a regular
user cannot monitor kernel level activity anymore. As such, with the
following cmdline:

  $ perf record -e cycles date

The perf tool first tries cycles:uk but then falls back to cycles:u as
can be seen in the perf report --header-only output:

  cmdline : /export/hda3/tmp/perf.tip record -e cycles ls
  event : name = cycles:u, , id = { 436186, ... }

This is okay as long as there is way to learn the priv level was changed
internally by the tool.

But consider a similar example:

  $ perf record -b -e cycles date
  Error:
  You may not have permission to collect stats.

Consider tweaking /proc/sys/kernel/perf_event_paranoid,
which controls use of the performance events system by
unprivileged users (without CAP_SYS_ADMIN).
...

Why is that treated differently given that the branch sampling inherits the
priv level of the first event in this case, i.e., cycles:u? It turns out
that the branch sampling code is more picky and also checks exclude_hv.

In the fallback path, perf record is setting exclude_kernel = 1, but it
does not change exclude_hv. This does not seem to match the restriction
imposed by paranoid = 2.

This patch fixes the problem by forcing exclude_hv = 1 in the fallback
for paranoid=2. With this in place:

  $ perf record -b -e cycles date
    cmdline : /export/hda3/tmp/perf.tip record -b -e cycles ls
    event : name = cycles:u, , id = { 436847, ... }

And the command succeeds as expected.

V2 fix a white space.

Committer testing:

After aplying the patch we get:

  [acme@quaco ~]$ perf record -b -e cycles date
  WARNING: Kernel address maps (/proc/{kallsyms,modules}) are restricted,
  check /proc/sys/kernel/kptr_restrict and /proc/sys/kernel/perf_event_paranoid.

  Samples in kernel functions may not be resolved if a suitable vmlinux
  file is not found in the buildid cache or in the vmlinux path.

  Samples in kernel modules won't be resolved at all.

  If some relocation was applied (e.g. kexec) symbols may be misresolved
  even with a suitable vmlinux or kallsyms file.

  [acme@quaco ~]$

That warning about restricted kernel maps will be suppressed in a follow
up patch, as perf_event_attr.exclude_kernel is set, i.e. no samples for
the kernel will be taken and thus no need for those maps.

The seccomp selftest goes to some length to build against older kernel

Commit 201766a20e30 ("ptrace: add PTRACE_GET_SYSCALL_INFO request")
introduces some additional macros, but doesn't do the #ifdef dance.
Let's add that dance here to avoid:

Subject: KVM: selftests: Move vm type into _vm_create() internally

Rather than passing the vm type from the top level to the end of vm
creation, let's simply keep that as an internal of kvm_vm struct and
decide the type in _vm_create().  Several reasons for doing this:

- The vm type is only decided by physical address width and currently
  only used in aarch64, so we've got enough information as long as
  we're passing vm_guest_mode into _vm_create(),

- This removes a loop dependency between the vm->type and creation of
  vms.  That's why now we need to parse vm_guest_mode twice sometimes,
  once in run_test() and then again in _vm_create().  The follow up
  patches will move on to clean up that as well so we can have a
  single place to decide guest machine types and so.

Note that this patch will slightly change the behavior of aarch64
tests in that previously most vm_create() callers will directly pass
in type==0 into _vm_create() but now the type will depend on
vm_guest_mode, however it shouldn't affect any user because all
vm_create() users of aarch64 will be using VM_MODE_DEFAULT guest
mode (which is VM_MODE_P40V48_4K) so at last type will still be zero.

Subject: KVM: selftests: Create VM earlier for dirty log test

Since we've just removed the dependency of vm type in previous patch,
now we can create the vm much earlier.  Note that to move it earlier
we used an approximation of number of extra pages but it should be
fine.

This prepares for the follow up patches to finally remove the
duplication of guest mode parsings.

Subject: KVM: selftests: Introduce VM_MODE_PXXV48_4K

The naming VM_MODE_P52V48_4K is explicit but unclear when used on
x86_64 machines, because x86_64 machines are having various physical
address width rather than some static values.  Here's some examples:

  - Intel Xeon E3-1220:  36 bits
  - Intel Core i7-8650:  39 bits
  - AMD   EPYC 7251:     48 bits

All of them are using 48 bits linear address width but with totally
different physical address width (and most of the old machines should
be less than 52 bits).

Let's create a new guest mode called VM_MODE_PXXV48_4K for current
x86_64 tests and make it as the default to replace the old naming of
VM_MODE_P52V48_4K because it shows more clearly that the PA width is
not really a constant.  Meanwhile we also stop assuming all the x86
machines are having 52 bits PA width but instead we fetch the real
vm->pa_bits from CPUID 0x80000008 during runtime.

We currently make this exclusively used by x86_64 but no other arch.

As a slight touch up, moving DEBUG macro from dirty_log_test.c to
kvm_util.h so lib can use it too.

From 52200d0d944e473142271773c41f5f490f3a821f Mon Sep 17 00:00:00 2001

Subject: KVM: selftests: Remove duplicate guest mode handling

Remove the duplication code in run_test() of dirty_log_test because
after some reordering of functions now we can directly use the outcome
of vm_create().

Meanwhile, with the new VM_MODE_PXXV48_4K, we can safely revert
b442324b58 too where we stick the x86_64 PA width to 39 bits for
dirty_log_test.

Subject: libnvdimm/nfit_test: Fix acpi_handle redefinition

After commit 62974fc389b3 ("libnvdimm: Enable unit test infrastructure
compile checks"), clang warns:

In file included from
../drivers/nvdimm/../../tools/testing/nvdimm/test/iomap.c:15:
../drivers/nvdimm/../../tools/testing/nvdimm/test/nfit_test.h:206:15:
warning: redefinition of typedef 'acpi_handle' is a C11 feature
[-Wtypedef-redefinition]
typedef void *acpi_handle;
              ^
../include/acpi/actypes.h:424:15: note: previous definition is here
typedef void *acpi_handle;      /* Actually a ptr to a NS Node */
              ^
1 warning generated.

The include chain:

iomap.c ->
    linux/acpi.h ->
        acpi/acpi.h ->
            acpi/actypes.h
    nfit_test.h

Avoid this by including linux/acpi.h in nfit_test.h, which allows us to
remove both the typedef and the forward declaration of acpi_object.

Subject: perf vendor events amd: Add L3 cache events for Family 17h
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Allow users to symbolically specify L3 events for Family 17h processors
using the existing AMD Uncore driver.

Source of events descriptions are from section 2.1.15.4.1 "L3 Cache PMC
Events" of the latest Family 17h PPR, available here:

  https://www.amd.com/system/files/TechDocs/55570-B1_PUB.zip

Opnly BriefDescriptions added, since they show with and without
the -v and --details flags.

Tested with:

 # perf stat -e l3_request_g1.caching_l3_cache_accesses,amd_l3/event=0x01,umask=0x80/,l3_comb_clstr_state.request_miss,amd_l3/event=0x06,umask=0x01/ perf bench mem memcpy -s 4mb -l 100 -f default

Subject: perf list: Allow plurals for metric, metricgroup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Enhance usability by allowing the same plurality used in the output
title, for the command line parameter.

BEFORE, perf deceitfully acts as if there are no metrics to be had:

  $ perf list metrics

  List of pre-defined events (to be used in -e):

  Metric Groups:

  $

But singular 'metric' shows a list of metrics:

  $ perf list metric

  List of pre-defined events (to be used in -e):

  Metrics:

    IPC
         [Instructions Per Cycle (per logical thread)]
    UPI
         [Uops Per Instruction]

AFTER, when asking for 'metrics', we actually see the metrics get listed:

  $ perf list metrics

  List of pre-defined events (to be used in -e):

  Metrics:

    IPC
         [Instructions Per Cycle (per logical thread)]
    UPI
         [Uops Per Instruction]

Subject: libtraceevent: Round up in tep_print_event() time precision

When testing the output of the old trace-cmd compared to the one that
uses the updated tep_print_event() logic, it was different in that the
time stamp precision in the old format would round up to the nearest
precision, where as the new logic truncates. Bring back the old method
of rounding up.

+================
+
+NAME
+----
+tep_print_event - Writes event information into a trace sequence.
+
+SYNOPSIS
+--------
+[verse]
+--
+*#include <event-parse.h>*
+*#include <trace-seq.h>*
+
+void *tep_print_event*(struct tep_handle pass:[*]_tep_, struct trace_seqpass:[*]_s_, struct tep_record pass:[*]_record_, const char pass:[*]_fmt_, _..._)
+--
+
+DESCRIPTION
+-----------
+
+The _tep_print_event()_ function parses the event information of the given
+_record_ and writes it into the trace sequence _s_, according to the format
+string _fmt_. The desired information is specified after the format string.
+The _fmt_ is printf-like format string, following arguments are supported:
+[verse]
+--
+	TEP_PRINT_PID, "%d"  - PID of the event.
+	TEP_PRINT_CPU, "%d"  - Event CPU.
+	TEP_PRINT_COMM, "%s" - Event command string.
+	TEP_PRINT_NAME, "%s" - Event name.
+	TEP_PRINT_LATENCY, "%s" - Latency of the event. It prints 4 or more
+			fields - interrupt state, scheduling state,
+			current context, and preemption count.
+			Field 1 is the interrupt enabled state:
+				d : Interrupts are disabled
+				. : Interrupts are enabled
+				X : The architecture does not support this
+				    information
+			Field 2 is the "need resched" state.
+				N : The task is set to call the scheduler when
+				    possible, as another higher priority task
+				    may need to be scheduled in.
+				. : The task is not set to call the scheduler.
+			Field 3 is the context state.
+				. : Normal context
+				s : Soft interrupt context
+				h : Hard interrupt context
+				H : Hard interrupt context which triggered
+				    during soft interrupt context.
+				z : NMI context
+				Z : NMI context which triggered during hard
+				    interrupt context
+			Field 4 is the preemption count.
+				. : The preempt count is zero.
+			On preemptible kernels (where the task can be scheduled
+			out in arbitrary locations while in kernel context), the
+			preempt count, when non zero, will prevent the kernel
+			from scheduling out the current task. The preempt count
+			number is displayed when it is not zero.
+			Depending on the kernel, it may show other fields
+			(lock depth, or migration disabled, which are unique to
+			specialized kernels).
+	TEP_PRINT_TIME, %d - event time stamp. A divisor and precision can be
+			specified as part of this format string:
+			"%precision.divisord". Example:
+			"%3.1000d" - divide the time by 1000 and print the first
+			3 digits before the dot. Thus, the time stamp
+			"123456000" will be printed as "123.456"
+	TEP_PRINT_INFO, "%s" - event information.
+	TEP_PRINT_INFO_RAW, "%s" - event information, in raw format.
+

Subject: libtraceevent: Man pages fix, rename tep_ref_get() to tep_get_ref()

The tep_ref_get() was renamed to tep_get_ref(), to be more consistent
with the other tep_ref_* APIs. However, in the man pages the API is
still with the old name. The documentation is fixed to reflect the
actual name of the API.

Subject: libtraceevent: Man pages fix, changes in event printing APIs

APIs for printing various trace event information were redesigned to be
more simple. However, the main libtraceevent man page was not updated
with those changes. The documentation is updated to describe the new
event print API.

Subject: libtraceevent: Add tep_get_event() in event-parse.h

The tep_get_event() function is an official libtracevent API, described
in the library man pages. However, it cannot be used by the library users because
it is not declared in the event-parse.h file, where all libtracevent APIs are.
The function declaration is added in event-parse.h file.

Subject: libtraceevent: Move traceevent plugins in its own subdirectory

All traceevent plugins code is moved to tools/lib/traceevent/plugins
subdirectory. It makes traceevent implementation in trace-cmd and in
kernel tree consistent. There is no changes in the way libtraceevent and
plugins are compiled and installed.

Committer notes:

Applied fixup provided by Steven, fixing the tools/perf/Makefile.perf
target for the plugin dynamic list file. Problem noticed when cross
building to aarch64 from a Ubuntu 19.04 container.

+libtraceevent(3)
+================
+
+NAME
+----
+tep_load_plugins, tep_unload_plugins - Load / unload traceevent plugins.
+
+SYNOPSIS
+--------
+[verse]
+--
+*#include <event-parse.h>*
+
+struct tep_plugin_list pass:[*]*tep_load_plugins*(struct tep_handle pass:[*]_tep_);
+void *tep_unload_plugins*(struct tep_plugin_list pass:[*]_plugin_list_, struct tep_handle pass:[*]_tep_);
+--
+
+DESCRIPTION
+-----------
+The _tep_load_plugins()_ function loads all plugins, located in the plugin
+directories. The _tep_ argument is trace event parser context.
+The plugin directories are :
+[verse]
+--
+	- System's plugin directory, defined at the library compile time. It
+	  depends on the library installation prefix and usually is
+	  _(install_preffix)/lib/traceevent/plugins_
+	- Directory, defined by the environment variable _TRACEEVENT_PLUGIN_DIR_
+	- User's plugin directory, located at _~/.local/lib/traceevent/plugins_
+--
+Loading of plugins can be controlled by the _tep_flags_, using the
+_tep_set_flag()_ API:
+[verse]
+--
+	_TEP_DISABLE_SYS_PLUGINS_	- do not load plugins, located in
+					the system's plugin directory.
+	_TEP_DISABLE_PLUGINS_		- do not load any plugins.
+--
+The _tep_set_flag()_ API needs to be called before _tep_load_plugins()_, if
+loading of all plugins is not the desired case.
+
+The _tep_unload_plugins()_ function unloads the plugins, previously loaded by
+_tep_load_plugins()_. The _tep_ argument is trace event parser context. The
+_plugin_list_ is the list of loaded plugins, returned by
+the _tep_load_plugins()_ function.
+
+RETURN VALUE
+------------
+The _tep_load_plugins()_ function returns a list of successfully loaded plugins,
+or NULL in case no plugins are loaded.
+
+EXAMPLE
+-------
+[source,c]
+--
+#include <event-parse.h>
+...
+struct tep_handle *tep = tep_alloc();
+...
+struct tep_plugin_list *plugins = tep_load_plugins(tep);
+if (plugins == NULL) {
+	/* no plugins are loaded */
+}
+...
+tep_unload_plugins(plugins, tep);
+--
+
+FILES

+[verse]
+--
+*event-parse.h*
+	Header file to include in order to have access to the library APIs.
+*-ltraceevent*
+	Linker switch to add when building a program that uses the library.

Subject: tools: Add missing stdio.h include to asm/bug.h header

We have a direct fprintf() call in the header, so we need stdio.h
include, otherwise it could fail compilation if there's no prior stdio.h
include directive.

Subject: perf tools: Rename 'struct perf_mmap' to 'struct mmap'

Rename 'struct perf_evlist' to 'struct evlist', so we don't have a name
clash when we add 'struct perf_mmap' to libperf.

From 9521b5f2d9d3e3fd6092fb9d7b00c914e7fa7d33 Mon Sep 17 00:00:00 2001
From: Jiri Olsa <jolsa@kernel.org>
Date: Sun, 28 Jul 2019 12:45:35 +0200
Subject: perf tools: Rename perf_evlist__mmap() to evlist__mmap()

Rename perf_evlist__mmap() to evlist__mmap(), so we don't have a name
clash when we add perf_evlist__mmap() in libperf.

From db6b7b138506ad537edd12d98f674722a643c150 Mon Sep 17 00:00:00 2001
From: Jiri Olsa <jolsa@kernel.org>
Date: Fri, 16 Aug 2019 16:19:55 +0200
Subject: perf tools: Rename perf_evlist__munmap() to evlist__munmap()

Rename perf_evlist__munmap() to evlist__munmap(), so we don't have a
name clash when we add perf_evlist__munmap() in libperf.

Subject: perf evlist: Adopt backwards ring buffer state enum

As this isn't used at all in mmap.h but in evlist.h, so to cut down the
header dependency tree, move it to where it is used.

Also add mmap.h to the places using it but previously getting it
indirectly via evlist.h.

Add missing pthread.h to evlist.h, as it has a pthread_t struct member
and was getting the header via mmap.h.

Noticed while processing a Jiri's libperf batch touching mmap.h, where
almost everything gets rebuilt because evlist.h is so popular, so cut
down't this rebuild the world party.

From 547740f7b357cd91cca1fab5d7bf3a37469f7587 Mon Sep 17 00:00:00 2001
From: Jiri Olsa <jolsa@kernel.org>
Date: Sat, 27 Jul 2019 22:07:44 +0200
Subject: libperf: Add perf_mmap struct

Add the perf_mmap struct to libperf.

The definition is added into:

  include/internal/mmap.h

which is not to be included by users, but shared within perf and
libperf.

Committer notes:

Remove unnecessary includes from tools/perf/lib/include/internal/mmap.h,
those will be readded as they become necessary, later in the series.

From deaf321913a7b1d440c5cd5c7766d47381c9b21b Mon Sep 17 00:00:00 2001
From: Jiri Olsa <jolsa@kernel.org>
Date: Mon, 2 Sep 2019 22:12:26 +0200
Subject: libperf: Move 'id' from 'struct evsel' to 'struct perf_evsel'

Move the 'id' array from 'struct evsel' to libperf's 'struct perf_evsel'.

Committer note:

Fix the tools/perf/util/cs-etm.c build, i.e. aarch64's CoreSight.

Subject: libperf: Add perf_evsel__alloc_id/perf_evsel__free_id functions

Add perf_evsel__alloc_id()/perf_evsel__free_id() functions to libperf as
internal functions.

Move 'struct perf_sample_id' to internal/evsel.h header and change
'struct perf_sample_id::evsel' to 'struct perf_evsel' and the related
code that touches it.

From: Jiri Olsa <jolsa@kernel.org>

Subject: libperf: Move 'page_size' global variable to libperf

We need the 'page_size' variable in libperf, so move it there.

Add a libperf_init() as a global libperf init function to obtain this
value via sysconf() at tool start.

Committer notes:

Add internal/lib.h to tools/perf/ files using 'page_size', sometimes
replacing util.h with it if that was the only reason for having util.h
included.

Subject: perf tools: No need to include internal/lib.h from util/util.h

That was done just to have users of writen() and readn(), that before
had their prototypes in util/util.h to get it without having to add an
include for internal/lib.h, but the right way is to add it and by now
all places already do it.

Fix a fallout were readlink() was used but unistd.h was being obtained
by luck thru util.h -> internal/lib.h, now to check why unistd.h is
being included there...

Subject: libperf: Use sys/types.h to get ssize_t, not unistd.h

The sys/types.h header looks more sensible, from its name we can gather
it should be there because of some needed typedef, and it is much
smaller than unistd.h, so use it and fix up the fallout in places where
it was being used for something else entirely but being obtained by
sheer luck, indirectly.

Subject: KVM: selftests: fix ucall on x86

After commit e8bb4755eea2("KVM: selftests: Split ucall.c into architecture
specific files") selftests which use ucall on x86 started segfaulting and
apparently it's gcc to blame: it "optimizes" ucall() function throwing away
va_start/va_end part because it thinks the structure is not being used.
Previously, it couldn't do that because the there was also MMIO version and
the decision which particular implementation to use was done at runtime.

With older gccs it's possible to solve the problem by adding 'volatile'
to 'struct ucall' but at least with gcc-8.3 this trick doesn't work.

'memory' clobber seems to do the job.

Subject: KVM: x86: Check kvm_rebooting in kvm_spurious_fault()

Explicitly check kvm_rebooting in kvm_spurious_fault() prior to invoking
BUG(), as opposed to assuming the caller has already done so.  Letting
kvm_spurious_fault() be called "directly" will allow VMX to better
optimize its low level assembly flows.

As a happy side effect, kvm_spurious_fault() no longer needs to be
marked as a dead end since it doesn't unconditionally BUG().

Subject: selftests, sched/membarrier: Add multi-threaded test

membarrier commands cover very different code paths if they are in
a single-threaded vs multi-threaded process. Therefore, exercise both
scenarios in the kernel selftests to increase coverage of this selftest.

From ca1252779f48ece225c6003e01c675abb91cf1b4 Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Date: Tue, 24 Sep 2019 15:41:51 -0300
Subject: perf evsel: Introduce evsel_fprintf.h

We already had evsel_fprintf.c, add its counterpart, so that we can
reduce evsel.h a bit more.

We needed a new perf_event_attr_fprintf.c file so as to have a separate
object to link with the python binding in tools/perf/util/python-ext-sources
and not drag symbol_conf, etc into the python binding.

Subject: perf evlist: Remove unused perf_evlist__fprintf() method

Ditch it, noone is using it, one more stdio.h include in a hot header.

Fix the fallout in parse-events.y, where we end up using a FILE pointer,
I think due to YYDEBUG being set and in some places, like Amazon Linux 1
we don't get stdio.h included by luck, like in most other places, add a
explicit stdio.h include directive.

Subject: perf tools: Replace needless mmap.h with what is needed, event.h

The perf_sample struct definition and the event_attr_init() are in
util/event.h, but some places were getting it thru an otherwise needless
util/mmap.h header, fix it by including util/event.h directly.

Subject: perf stat: Fix free memory access / memory leaks in metrics

Make sure to not free the name passed in by the caller, but free all the
allocated ids when parsing expressions.

The loop at the end knows that the first entry shouldn't be freed, so
make sure the caller name is the first entry.

Fixes

Subject: perf evlist: Fix access of freed id arrays

I'm not fully sure if this is the correct fix, but without this I get
crashes on more complex perf stat metric usages. The problem is that
part of the state gets freed when a weak group fails, but then is later
still used. Just don't free the ids, we're going to reuse them anyways
on the weak group retry.

For example:

  % perf stat -M IpB,IpCall,IpTB,IPC,Retiring_SMT,Frontend_Bound_SMT,Kernel_Utilization,CPU_Utilization --metric-only -a -I 1000 sleep 2

  crashes and gives in valgrind:

Subject: perf build: Add detection of java-11-openjdk-devel package

With Java 11 there is no seperate JRE anymore.

Details:

  https://coderanch.com/t/701603/java/JRE-JDK

Therefore the detection of the JRE needs to be adapted.

This change works for s390 and x86.  I have not tested other platforms.

Committer testing:

Continues to work with the OpenJDK 8:

  $ rm -f ~acme/lib64/libperf-jvmti.so
  $ rpm -qa | grep jdk-devel
  java-1.8.0-openjdk-devel-1.8.0.222.b10-0.fc30.x86_64

Subject: perf parser: Remove needless include directives

They go on accumulating there like the debug.h one, that was introduced
here:

  f23610245c1a ("perf list: Add debug support for outputing alias string")

But then, when that need is removed via:

  2073ad3326b7 ("perf tools: Factor out PMU matching in parser")

The thing stays there, so continue the house cleaning spree...

list.h not needed, no macros from there are used, and 'struct
list_head' is in linux/types.h, ditto for util.h, no need for that as
well.

Subject: selftests/bpf: adjust strobemeta loop to satisfy latest clang

Some recent changes in latest Clang started causing the following
warning when unrolling strobemeta test case main loop:

  progs/strobemeta.h:416:2: warning: loop not unrolled: the optimizer was
  unable to perform the requested transformation; the transformation might
  be disabled or specified as part of an unsupported transformation
  ordering [-Wpass-failed=transform-warning]

This patch simplifies loop's exit condition to depend only on constant
max iteration number (STROBE_MAX_MAP_ENTRIES), while moving early
termination logic inside the loop body. The changes are equivalent from
program logic standpoint, but fixes the warning. It also appears to
improve generated BPF code, as it fixes previously failing non-unrolled
strobemeta test cases.

 copy)

As was already noted in rbtree.h, the logic to cache rb_first (or
rb_last) can easily be implemented externally to the core rbtree api.

This commit takes the changes applied to the include/linux/ and lib/
rbtree files in 9f973cb38088 ("lib/rbtree: avoid generating code twice
for the cached versions"), and applies these to the
tools/include/linux/ and tools/lib/ files as well to keep them
synchronized.

From 444b8a83f1e01584ff2d53f5951d8e836c0070b5 Mon Sep 17 00:00:00 2001

Subject: augmented rbtree: add comments for RB_DECLARE_CALLBACKS macro

Patch series "make RB_DECLARE_CALLBACKS more generic", v3.

These changes are intended to make the RB_DECLARE_CALLBACKS macro more
generic (allowing the aubmented subtree information to be a struct instead
of a scalar).

I have verified the compiled lib/interval_tree.o and mm/mmap.o files to
check that they didn't change.  This held as expected for interval_tree.o;
mmap.o did have some changes which could be reverted by marking
__vma_link_rb as noinline.  I did not add such a change to the patchset; I
felt it was reasonable enough to leave the inlining decision up to the
compiler.

This patch (of 3):

Add a short comment summarizing the arguments to RB_DECLARE_CALLBACKS.
The arguments are also now capitalized.  This copies the style of the
INTERVAL_TREE_DEFINE macro.

No functional changes in this commit, only comments and capitalization.

Subject: augmented rbtree: add new RB_DECLARE_CALLBACKS_MAX macro

Add RB_DECLARE_CALLBACKS_MAX, which generates augmented rbtree callbacks
for the case where the augmented value is a scalar whose definition
follows a max(f(node)) pattern.  This actually covers all present uses of
RB_DECLARE_CALLBACKS, and saves some (source) code duplication in the
various RBCOMPUTE function definitions.

From 6d2052d188d962ffb7ad3d413e6ffd5f276aec94 Mon Sep 17 00:00:00 2001
From: Michel Lespinasse <walken@google.com>
Date: Wed, 25 Sep 2019 16:46:10 -0700
Subject: augmented rbtree: rework the RB_DECLARE_CALLBACKS macro definition

Change the definition of the RBCOMPUTE function.  The propagate callback
repeatedly calls RBCOMPUTE as it moves from leaf to root.  it wants to
stop recomputing once the augmented subtree information doesn't change.
This was previously checked using the == operator, but that only works
when the augmented subtree information is a scalar field.  This commit
modifies the RBCOMPUTE function so that it now sets the augmented subtree
information instead of returning it, and returns a boolean value
indicating if the propagate callback should stop.

The motivation for this change is that I want to introduce augmented
rbtree uses where the augmented data for the subtree is a struct instead
of a scalar.

Subject: ipv6: do not free rt if FIB_LOOKUP_NOREF is set on suppress rule

Commit 7d9e5f422150 removed references from certain dsts, but accounting
for this never translated down into the fib6 suppression code. This bug
was triggered by WireGuard users who use wg-quick(8), which uses the
"suppress-prefix" directive to ip-rule(8) for routing all of their
internet traffic without routing loops. The test case added here
causes the reference underflow by causing packets to evaluate a suppress
rule.

Fixes: 7d9e5f422150 ("ipv6: convert major tx path to use RT6_LOOKUP_F_DST_NOREF")

Subject: libbpf: Teach btf_dumper to emit stand-alone anonymous enum
 definitions

BTF-to-C converter previously skipped anonymous enums in an assumption
that those are embedded in struct's field definitions. This is not
always the case and a lot of kernel constants are defined as part of
anonymous enums. This change fixes the logic by eagerly marking all
types as either referenced by any other type or not. This is enough to
distinguish two classes of anonymous enums and emit previously omitted
enum definitions.

Subject: perf tests: Avoid raising SEGV using an obvious NULL dereference

An optimized build such as:

  make -C tools/perf CLANG=1 CC=clang EXTRA_CFLAGS="-O3

will turn the dereference operation into a ud2 instruction, raising a
SIGILL rather than a SIGSEGV. Use raise(..) for correctness and clarity.

Similar issues were addressed in Numfor Mbiziwo-Tiapo's patch:

  https://lkml.org/lkml/2019/7/8/1234

Committer testing:

Before:

  [root@quaco ~]# perf test hooks
  55: perf hooks                                            : Ok
  [root@quaco ~]# perf test -v hooks
  55: perf hooks                                            :
  --- start ---
  test child forked, pid 17092
  SIGSEGV is observed as expected, try to recover.
  Fatal error (SEGFAULT) in perf hook 'test'
  test child finished with 0
  ---- end ----
  perf hooks: Ok
  [root@quaco ~]#

After:

  [root@quaco ~]# perf test hooks
  55: perf hooks                                            : Ok

Subject: perf docs: Allow man page date to be specified

With this change if a perf_date parameter is provided to asciidoc then
it will override the default date written to the man page metadata.

Without this change, or if the perf_date isn't specified, then the
current date is written to the metadata.

Having this parameter allows the metadata to be constant if builds
happen on different dates.

The name of the parameter is intended to be consistent with the existing
perf_version parameter.

Subject: KVM: selftests: x86: clarify what is reported on KVM_GET_MSRS failure

When KVM_GET_MSRS fail the report looks like

==== Test Assertion Failure ====
  lib/x86_64/processor.c:1089: r == nmsrs
  pid=28775 tid=28775 - Argument list too long
     1	0x000000000040a55f: vcpu_save_state at processor.c:1088 (discriminator 3)
     2	0x00000000004010e3: main at state_test.c:171 (discriminator 4)
     3	0x00007fb8e69223d4: ?? ??:0
     4	0x0000000000401287: _start at ??:?
  Unexpected result from KVM_GET_MSRS, r: 36 (failed at 194)

and it's not obvious that '194' here is the failed MSR index and that
it's printed in hex. Change that.

Subject: mlxsw: spectrum: Clear VLAN filters during port initialization

When a port is created, its VLAN filters are not cleared by the
firmware. This causes tagged packets to be later dropped by the ingress
STP filters, which default to DISCARD state.

The above did not matter much until commit b5ce611fd96e ("mlxsw:
spectrum: Add devlink-trap support") where we exposed the drop reason to
users.

Without this patch, the drop reason users will see is not consistent. If
a port is enslaved to a VLAN-aware bridge and a packet with an invalid
VLAN tries to ingress the bridge, it will be dropped due to ingress STP
filter. If the VLAN is later enabled and then disabled, the packet will
be dropped by the ingress VLAN filter despite the above being a
seemingly NOP operation.

Fix this by clearing all the VLAN filters during port initialization.
Adjust the test accordingly.

Subject: tools: bpf: Use !building_out_of_srctree to determine srctree

make TARGETS=bpf kselftest fails with:

Makefile:127: tools/build/Makefile.include: No such file or directory

When the bpf tool make is invoked from tools Makefile, srctree is
cleared and the current logic check for srctree equals to empty
string to determine srctree location from CURDIR.

When the build in invoked from selftests/bpf Makefile, the srctree
is set to "." and the same logic used for srctree equals to empty is
needed to determine srctree.

Check building_out_of_srctree undefined as the condition for both
cases to fix "make TARGETS=bpf kselftest" build failure.

This triggers these changes in the kernel sources, automagically
supporting these new ioctls in the 'perf trace' beautifiers.

Soon this will be used in things like filter expressions for tracepoints
in 'perf record', 'perf trace', 'perf top', i.e. filter expressions will
do a lookup to turn things like USBDEVFS_WAIT_FOR_RESUME into _IO('U',
35) before associating the tracepoint expression to tracepoint perf
event.

That don't trigger any changes in tooling, as it so far is used only
for:

  $ grep -l 'fs\.h' tools/perf/trace/beauty/*.sh | xargs grep regex=
  tools/perf/trace/beauty/rename_flags.sh:regex='^[[:space:]]*#[[:space:]]*define[[:space:]]+RENAME_([[:alnum:]_]+)[[:space:]]+\(1[[:space:]]*<<[[:space:]]*([[:xdigit:]]+)[[:space:]]*\)[[:space:]]*.*'

  $

This silences this perf build warning:

Subject: tools headers kvm: Sync kvm headers with the kernel sources

To pick the changes in:

  200824f55eef ("KVM: s390: Disallow invalid bits in kvm_valid_regs and kvm_dirty_regs")
  4a53d99dd0c2 ("KVM: VMX: Introduce exit reason for receiving INIT signal on guest-mode")
  7396d337cfad ("KVM: x86: Return to userspace with internal error on unexpected exit reason")
  92f35b751c71 ("KVM: arm/arm64: vgic: Allow more than 256 vcpus for KVM_IRQ_LINE")

None of them trigger any changes in tooling, this time this is just to silence
these perf build warnings:

From 7d4c85b7035eb2f9ab217ce649dcd1bfaf0cacd3 Mon Sep 17 00:00:00 2001

Subject: perf llvm: Don't access out-of-scope array

The 'test_dir' variable is assigned to the 'release' array which is
out-of-scope 3 lines later.

Extend the scope of the 'release' array so that an out-of-scope array
isn't accessed.

Bug detected by clang's address sanitizer.

Fixes: 07bc5c699a3d ("perf tools: Make fetch_kernel_version() publicly available")

Subject: perf vendor events s390: Use s390 machine name instead of type 8561

In the pmu-events directory for JSON file definitions use the
official machine name IBM z15 instead of machine type number
8561. This is consistent with previous machines.

From ee212d6ea20887c0ef352be8563ca13dbf965906 Mon Sep 17 00:00:00 2001

Subject: perf map: Fix overlapped map handling

Whenever an mmap/mmap2 event occurs, the map tree must be updated to add a new
entry. If a new map overlaps a previous map, the overlapped section of the
previous map is effectively unmapped, but the non-overlapping sections are
still valid.

maps__fixup_overlappings() is responsible for creating any new map entries from
the previously overlapped map. It optionally creates a before and an after map.

When creating the after map the existing code failed to adjust the map.pgoff.
This meant the new after map would incorrectly calculate the file offset
for the ip. This results in incorrect symbol name resolution for any ip in the
after region.

Make maps__fixup_overlappings() correctly populate map.pgoff.

Add an assert that new mapping matches old mapping at the beginning of
the after map.

Committer-testing:

Validated correct parsing of libcoreclr.so symbols from .NET Core 3.0 preview9
(which didn't strip symbols).

Preparation:

  ~/dotnet3.0-preview9/dotnet new webapi -o perfSymbol
  cd perfSymbol
  ~/dotnet3.0-preview9/dotnet publish
  perf record ~/dotnet3.0-preview9/dotnet \
      bin/Debug/netcoreapp3.0/publish/perfSymbol.dll
  ^C

Before:

  perf script --show-mmap-events 2>&1 | grep -e MMAP -e unknown |\
     grep libcoreclr.so | head -n 4
        dotnet  1907 373352.698780: PERF_RECORD_MMAP2 1907/1907: \

All the [unknown] symbols were resolved.

Subject: perf inject jit: Fix JIT_CODE_MOVE filename

During perf inject --jit, JIT_CODE_MOVE records were injecting MMAP records
with an incorrect filename. Specifically it was missing the ".so" suffix.

Further the JIT_CODE_LOAD record were silently truncating the
jr->load.code_index field to 32 bits before generating the filename.

Make both records emit the same filename based on the full 64 bit
code_index field.

Fixes: 9b07e27f88b9 ("perf inject: Add jitdump mmap injection support")

Subject: perf docs: Correct and clarify jitdump spec

Specification claims latest version of jitdump file format is 2. Current
jit dump reading code treats 1 as the latest version.

Correct spec to match code.

The original language made it unclear the value to be written in the
magic field.

Revise language that the writer always writes the same value. Specify
that the reader uses the value to detect endian mismatches.

Subject: perf script brstackinsn: Fix recovery from LBR/binary mismatch

When the LBR data and the instructions in a binary do not match the loop
printing instructions could get confused and print a long stream of
bogus <bad> instructions.

The problem was that if the instruction decoder cannot decode an
instruction it ilen wasn't initialized, so the loop going through the
basic block would continue with the previous value.

Harden the code to avoid such problems:

- Make sure ilen is always freshly initialized and is 0 for bad
  instructions.

- Do not overrun the code buffer while printing instructions

- Print a warning message if the final jump is not on an instruction
  boundary.

Subject: perf jevents: Fix period for Intel fixed counters

The Intel fixed counters use a special table to override the JSON
information.

During this override the period information from the JSON file got
dropped, which results in inst_retired.any and similar running with
frequency mode instead of a period.

Just specify the expected period in the table.

The callers of symbol__annotate2() use symbol__strerror_disassemble() to
convert its failure returns into a human readable string, so
propagate error values from functions it calls, starting with
perf_env__arch() that when fails the right thing to do is to look at
'errno' to see why its possible call to uname() failed.

Subject: perf annotate: Propagate the symbol__annotate() error return

We were just returning -1 in symbol__annotate() when symbol__annotate()
failed, propagate its error as it is used later to pass to
symbol__strerror_disassemble() to present a error message to the user,
that in some cases were getting:

  "Invalid -1 error code"

Fix it to propagate the error.

They are called from symbol__annotate() and to propagate errors that can
help understand the problem make them return what
symbol__strerror_disassemble() known, i.e. errno codes and other
annotation specific errors in a special, out of errnos, range.

Subject: perf annotate: Don't return -1 for error when doing BPF disassembly

Return errno when open_memstream() fails and add two new speciall error
codes for when an invalid, non BPF file or one without BTF is passed to
symbol__disassemble_bpf(), so that its callers can rely on
symbol__strerror_disassemble() to convert that to a human readable error
message that can help figure out what is wrong, with hints even.

Subject: libbpf: handle symbol versioning properly for libbpf.a

bcc uses libbpf repo as a submodule. It brings in libbpf source
code and builds everything together to produce shared libraries.
With latest libbpf, I got the following errors:
  /bin/ld: libbcc_bpf.so.0.10.0: version node not found for symbol xsk_umem__create@LIBBPF_0.0.2
  /bin/ld: failed to set dynamic section sizes: Bad value
  collect2: error: ld returned 1 exit status
  make[2]: *** [src/cc/libbcc_bpf.so.0.10.0] Error 1

In xsk.c, we have
  asm(".symver xsk_umem__create_v0_0_2, xsk_umem__create@LIBBPF_0.0.2");
  asm(".symver xsk_umem__create_v0_0_4, xsk_umem__create@@LIBBPF_0.0.4");
The linker thinks the built is for LIBBPF but cannot find proper version
LIBBPF_0.0.2/4, so emit errors.

I also confirmed that using libbpf.a to produce a shared library also
has issues:
  -bash-4.4$ cat t.c
  extern void *xsk_umem__create;
  void * test() { return xsk_umem__create; }
  -bash-4.4$ gcc -c -fPIC t.c
  -bash-4.4$ gcc -shared t.o libbpf.a -o t.so
  /bin/ld: t.so: version node not found for symbol xsk_umem__create@LIBBPF_0.0.2
  /bin/ld: failed to set dynamic section sizes: Bad value
  collect2: error: ld returned 1 exit status
  -bash-4.4$

Symbol versioning does happens in commonly used libraries, e.g., elfutils
and glibc. For static libraries, for a versioned symbol, the old definitions
will be ignored, and the symbol will be an alias to the latest definition.
For example, glibc sched_setaffinity is versioned.
  -bash-4.4$ readelf -s /usr/lib64/libc.so.6 | grep sched_setaffinity
     756: 000000000013d3d0    13 FUNC    GLOBAL DEFAULT   13 sched_setaffinity@GLIBC_2.3.3
     757: 00000000000e2e70   455 FUNC    GLOBAL DEFAULT   13 sched_setaffinity@@GLIBC_2.3.4
    1800: 0000000000000000     0 FILE    LOCAL  DEFAULT  ABS sched_setaffinity.c
    4228: 00000000000e2e70   455 FUNC    LOCAL  DEFAULT   13 __sched_setaffinity_new
    4648: 000000000013d3d0    13 FUNC    LOCAL  DEFAULT   13 __sched_setaffinity_old
    7338: 000000000013d3d0    13 FUNC    GLOBAL DEFAULT   13 sched_setaffinity@GLIBC_2
    7380: 00000000000e2e70   455 FUNC    GLOBAL DEFAULT   13 sched_setaffinity@@GLIBC_
  -bash-4.4$
For static library, the definition of sched_setaffinity aliases to the new definition.
  -bash-4.4$ readelf -s /usr/lib64/libc.a | grep sched_setaffinity
  File: /usr/lib64/libc.a(sched_setaffinity.o)
     8: 0000000000000000   455 FUNC    GLOBAL DEFAULT    1 __sched_setaffinity_new
    12: 0000000000000000   455 FUNC    WEAK   DEFAULT    1 sched_setaffinity

For both elfutils and glibc, additional macros are used to control different handling
of symbol versioning w.r.t static and shared libraries.
For elfutils, the macro is SYMBOL_VERSIONING
(https://sourceware.org/git/?p=elfutils.git;a=blob;f=lib/eu-config.h).
For glibc, the macro is SHARED
(https://sourceware.org/git/?p=glibc.git;a=blob;f=include/shlib-compat.h;hb=refs/heads/master)

This patch used SHARED as the macro name. After this patch, the libbpf.a has
  -bash-4.4$ readelf -s libbpf.a | grep xsk_umem__create
     372: 0000000000017145  1190 FUNC    GLOBAL DEFAULT    1 xsk_umem__create_v0_0_4
     405: 0000000000017145  1190 FUNC    GLOBAL DEFAULT    1 xsk_umem__create
     499: 00000000000175eb   103 FUNC    GLOBAL DEFAULT    1 xsk_umem__create_v0_0_2
  -bash-4.4$
No versioned symbols for xsk_umem__create.
The libbpf.a can be used to build a shared library succesfully.
  -bash-4.4$ cat t.c
  extern void *xsk_umem__create;
  void * test() { return xsk_umem__create; }
  -bash-4.4$ gcc -c -fPIC t.c
  -bash-4.4$ gcc -shared t.o libbpf.a -o t.so
  -bash-4.4$

Subject: selftests: Add kselftest-all and kselftest-install targets

Add kselftest-all target to build tests from the top level
Makefile. This is to simplify kselftest use-cases for CI and
distributions where build and test systems are different.

Current kselftest target builds and runs tests on a development
system which is a developer use-case.

Add kselftest-install target to install tests from the top level
Makefile. This is to simplify kselftest use-cases for CI and
distributions where build and test systems are different.

This change addresses requests from developers and testers to add
support for installing kselftest from the main Makefile.

In addition, make the install directory the same when install is
run using "make kselftest-install" or by running kselftest_install.sh.
Also fix the INSTALL_PATH variable conflict between main Makefile and
selftests Makefile.

Subject: kselftest: add capability to skip chosen TARGETS

Let the user specify an optional TARGETS skiplist through the new optional
SKIP_TARGETS Makefile variable.

It is easier to skip at will using a reduced and well defined list of
possibly problematic targets with SKIP_TARGETS than to provide a partially
stripped down list of good targets using the usual TARGETS variable.

Subject: selftests/kselftest/runner.sh: Add 45 second timeout per test

Commit a745f7af3cbd ("selftests/harness: Add 30 second timeout per
test") solves the problem of kselftest_harness.h-using binary tests
possibly hanging forever. However, scripts and other binaries can still
hang forever. This adds a global timeout to each test script run.

To make this configurable (e.g. as needed in the "rtc" test case),
include a new per-test-directory "settings" file (similar to "config")
that can contain kselftest-specific settings. The first recognized field
is "timeout".

Additionally, this splits the reporting for timeouts into a specific
"TIMEOUT" not-ok (and adds exit code reporting in the remaining case).

Subject: selftests: watchdog: Validate optional file argument

The newly added optional file argument does not validate if the
file is indeed a watchdog, e.g.:

./watchdog-test  -f /dev/zero
Watchdog Ticking Away!

Fix it by confirming that the WDIOC_GETSUPPORT ioctl succeeds.

Subject: selftests: kvm: Fix libkvm build error

Fix the following build error from "make TARGETS=kvm kselftest":

libkvm.a(assert.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIC

This error is seen when build is done from the main Makefile using
kselftest target. In this case KBUILD_CPPFLAGS and CC_OPTION_CFLAGS
are defined.

When build is invoked using:

"make -C tools/testing/selftests/kvm" KBUILD_CPPFLAGS and CC_OPTION_CFLAGS
aren't defined.

There is no need to pass in KBUILD_CPPFLAGS and CC_OPTION_CFLAGS for the
check to determine if --no-pie is necessary, which is the case when these
two aren't defined when "make -C tools/testing/selftests/kvm" runs.

Fix it by simplifying the no-pie-option logic. With this change, both
build variations work.

"make TARGETS=kvm kselftest"
"make -C tools/testing/selftests/kvm"

Subject: udp: only do GSO if # of segs > 1

Prior to this change an application sending <= 1MSS worth of data and
enabling UDP GSO would fail if the system had SW GSO enabled, but the
same send would succeed if HW GSO offload is enabled. In addition to this
inconsistency the error in the SW GSO case does not get back to the
application if sending out of a real device so the user is unaware of this
failure.

With this change we only perform GSO if the # of segments is > 1 even
if the application has enabled segmentation. I've also updated the
relevant udpgso selftests.

Many distributions enable rp_filter. However, the flow dissector test
generates packets that have 1.1.1.1 set as (inner) source address without
this address being reachable. This causes the selftest to fail.

The selftests should not assume a particular initial configuration. Switch
off rp_filter.

Newer versions of GCC (>= 9) demand that the size of the string to be

Thus, the NULL char has to be taken into account on strncpy.

This will avoid the following compiling error:

Subject: perf evlist: Fix fix for freed id arrays

In the earlier fix for the memory overrun of id arrays I managed to typo
the wrong event in the fix.

Of course we need to close the current event in the loop, not the
original failing event.

The same test case as in the original patch still passes.

Subject: perf tools: Fix mode setting in copyfile_mode_ns()

slow_copyfile() opens the file by name, so "write" permissions must not
be removed in copyfile_mode_ns() before calling slow_copyfile().

Example:

 Before:

  $ sudo chmod +r /proc/kcore
  $ sudo setcap "cap_sys_admin,cap_sys_ptrace,cap_syslog,cap_sys_rawio=ep" tools/perf/perf
  $ tools/perf/perf buildid-cache -k /proc/kcore
  Couldn't add /proc/kcore

 After:

  $ sudo chmod +r /proc/kcore
  $ sudo setcap "cap_sys_admin,cap_sys_ptrace,cap_syslog,cap_sys_rawio=ep" tools/perf/perf
  $ tools/perf/perf buildid-cache -v -k /proc/kcore
  kcore added to build-id cache directory /home/ahunter/.debug/[kernel.kcore]/37e340b1b5a7cf4f57ba8de2bc777359588a957f/2019100709562289

Subject: tools headers kvm: Sync kvm.h headers with the kernel sources

To pick the changes in:

  344c6c804703 ("KVM/Hyper-V: Add new KVM capability KVM_CAP_HYPERV_DIRECT_TLBFLUSH")
  dee04eee9182 ("KVM: RISC-V: Add KVM_REG_RISCV for ONE_REG interface")

These trigger the rebuild of this object:

  CC       /tmp/build/perf/trace/beauty/ioctl.o

But do not result in any change in tooling, as the additions are not
being used in any table generatator.

This silences this perf build warning:

The memory @orig_flags is allocated by strdup(), it is freed on the

Fix this by adding free(orig_flags) on the error path.

Subject: mm/gup_benchmark: add a missing "w" to getopt string

Even though gup_benchmark.c has code to handle the -w command-line option,
the "w" is not part of the getopt string.  It looks as if it has been
missing the whole time.

On my machine, this leads naturally to the following predictable result:

  $ sudo ./gup_benchmark -w
  ./gup_benchmark: invalid option -- 'w'

...which is fixed with this commit.

vmx_set_nested_state_test() checks if VMX is supported twice: in the very
beginning (and skips the whole test if it's not) and before doing
test_vmx_nested_state(). One should be enough.

Subject: selftests: kvm: fix sync_regs_test with newer gccs

Commit 204c91eff798a ("KVM: selftests: do not blindly clobber registers in
 guest asm") was intended to make test more gcc-proof, however, the result
is exactly the opposite: on newer gccs (e.g. 8.2.1) the test breaks with

==== Test Assertion Failure ====
  x86_64/sync_regs_test.c:168: run->s.regs.regs.rbx == 0xBAD1DEA + 1
  pid=14170 tid=14170 - Invalid argument
     1	0x00000000004015b3: main at sync_regs_test.c:166 (discriminator 6)
     2	0x00007f413fb66412: ?? ??:0
     3	0x000000000040191d: _start at ??:?
  rbx sync regs value incorrect 0x1.

Apparently, compile is still free to play games with registers even
when they have variables attached.

Re-write guest code with 'asm volatile' by embedding ucall there and
making sure rbx is preserved.
