The Makefile lacks a couple of line continuation backslashes
in an `if' clause, which produces an error when make versions
prior to 4.x are used for building the tests.

I recently noticed a crash on arm64 when feeding a bogus index
into BPF tail call helper. The crash would not occur when the
interpreter is used, but only in case of JIT. Output looks as
follows:

In this case the index used in BPF r3 is the same as in r1
at the time of the call, meaning we fed a pointer as index;
here, it had the value 0xffff808fd7cf0500 which sits in x2.
While I found tail calls to be working in general (also for
hitting the error cases), I noticed the following in the code
emission:
# bpftool p d j i 988
[...]
38: ldr w10, [x1,x10]
3c: cmp w2, w10
40: b.ge 0x000000000000007c <-- signed cmp
44: mov x10, #0x20 // #32
48: cmp x26, x10

64: cbz x11, 0x000000000000007c
[...]
Meaning, the tests passed because commit ddb55992b04d ("arm64:
bpf: implement bpf_tail_call() helper") was using signed compares
instead of unsigned which as a result had the test wrongly passing.
Change this but also the tail call count test both into unsigned
and cap the index as u32. Latter we did as well in 90caccdd8cc0
("bpf: fix bpf_tail_call() x64 JIT") and is needed in addition here,
too. Tested on HiSilicon Hi1616.
Result after patch:
# bpftool p d j i 268

Both glibc and the kernel have in6_* macros definitions. Build fails

Since both glibc and the kernel have in6_* macros definitions, use the
one from glibc. Kernel headers will check for previous libc definitions
by including include/linux/libc-compat.h.

The ldt_gdt and ptrace_syscall selftests, even in their 64-bit variant, use
hard-coded 32-bit syscall numbers and call "int $0x80".
This will fail on 64-bit systems with CONFIG_IA32_EMULATION=y disabled.
Therefore, do not build these tests if we cannot build 32-bit binaries
(which should be a good approximation for CONFIG_IA32_EMULATION=y being enabled).

On 64-bit builds, we should not rely on "int $0x80" working (it only does if
CONFIG_IA32_EMULATION=y is enabled). To keep the "Set TF and check int80"
test running on 64-bit installs with CONFIG_IA32_EMULATION=y enabled, build
this test only if we can also build 32-bit binaries (which should be a
good approximation for that).

Pull powerpc fixes from Michael Ellerman:
"A larger batch of fixes than we'd like. Roughly 1/3 fixes for new
code, 1/3 fixes for stable and 1/3 minor things.
There's four commits fixing bugs when using 16GB huge pages on hash,
caused by some of the preparatory changes for pkeys.
Two fixes for bugs in the enhanced IRQ soft masking for local_t, one
of which broke KVM in some circumstances.
Four fixes for Power9. The most bizarre being a bug where futexes
stopped working because a NULL pointer dereference didn't trap during
early boot (it aliased the kernel mapping). A fix for memory hotplug
when using the Radix MMU, and a fix for live migration of guests using
the Radix MMU.
Two fixes for hotplug on pseries machines. One where we weren't
correctly updating NUMA info when CPUs are added and removed. And the
other fixes crashes/hangs seen when doing memory hot remove during
boot, which is apparently a thing people do.
Finally a handful of build fixes for obscure configs and other minor
fixes.

With glibc 2.26 'struct ucontext' is removed to improve POSIX
compliance, which breaks powerpc/alignment_handler selftest. Fix the
test by using ucontext_t. Tested on ppc, works with older glibc
versions as well.
Fixes the following:
alignment_handler.c: In function ‘sighandler’:
alignment_handler.c:68:5: error: dereferencing pointer to incomplete type ‘struct ucontext’
ucp->uc_mcontext.gp_regs[PT_NIP] += 4;

On 64-bit builds, we should not rely on "int $0x80" working (it only does if
CONFIG_IA32_EMULATION=y is enabled).
Without this patch, the move test may succeed, but the "int $0x80" causes
a segfault, resulting in a false negative output of this self-test.

====================
pull-request: bpf 2018-02-09
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Two fixes for BPF sockmap in order to break up circular map references
from programs attached to sockmap, and detaching related sockets in
case of socket close() event. For the latter we get rid of the
smap_state_change() and plug into ULP infrastructure, which will later
also be used for additional features anyway such as TX hooks. For the
second issue, dependency chain is broken up via map release callback
to free parse/verdict programs, all from John.
2) Fix a libbpf relocation issue that was found while implementing XDP
support for Suricata project. Issue was that when clang was invoked
with default target instead of bpf target, then various other e.g.
debugging relevant sections are added to the ELF file that contained
relocation entries pointing to non-BPF related sections which libbpf
trips over instead of skipping them. Test cases for libbpf are added
as well, from Jesper.
3) Various misc fixes for bpftool and one for libbpf: a small addition
to libbpf to make sure it recognizes all standard section prefixes.
Then, the Makefile in bpftool/Documentation is improved to explicitly
check for rst2man being installed on the system as we otherwise risk
installing empty man pages; the man page for bpftool-map is corrected
and a set of missing bash completions added in order to avoid shipping
bpftool where the completions are only partially working, from Quentin.
4) Fix applying the relocation to immediate load instructions in the
nfp JIT which were missing a shift, from Jakub.
5) Two fixes for the BPF kernel selftests: handle CONFIG_BPF_JIT_ALWAYS_ON=y
gracefully in test_bpf.ko module and mark them as FLAG_EXPECTED_FAIL
in this case; and explicitly delete the veth devices in the two tests
test_xdp_{meta,redirect}.sh before dismantling the netnses as when
selftests are run in batch mode, then workqueue to handle destruction
might not have finished yet and thus veth creation in next test under
same dev name would fail, from Yonghong.
6) Fix test_kmod.sh to check the test_bpf.ko module path before performing
an insmod, and fallback to modprobe. Especially the latter is useful
when having a device under test that has the modules installed instead,
from Naresh.

This script test_libbpf.sh will be part of the 'make run_tests'
invocation, but can also be invoked manually in this directory,
and a verbose mode can be enabled via setting the environment
variable $VERBOSE like:
$ VERBOSE=yes ./test_libbpf.sh
The script contains some tests that are commented out, as they
currently fail. They are reminders about what we need to improve
for the libbpf loader library.

V2: Moved program into selftests/bpf from tools/libbpf
This program can be used on its own for testing/debugging if a
BPF ELF-object file can be loaded with libbpf (from tools/lib/bpf).
If something is wrong with the ELF object, the program have
a --debug mode that will display the ELF sections and especially
the skipped sections. This allows for quickly identifying the
problematic ELF section number, which can be corrolated with the
readelf tool.
The program signal error via return codes, and also have
a --quiet mode, which is practical for use in scripts like
selftests/bpf.

Al Viro discovered a bug in the removing of function probes where if it had
a '*' at the beginning, it would fail to find any matches. That is, because
it reset the glob search string to the the initial string with a "MATCH_END"
type, instead of skipping the wildcard "*" it included it, where it would
not match any functions because "*" was being treated as a normal character
and not a wildcard one.

If a probe is attached to a static function that is in multiple files with
the same name, removing it by name will remove all instances:
# grep jump_label_unlock set_ftrace_filter
jump_label_unlock:traceoff:unlimited
jump_label_unlock:traceoff:unlimited
# echo '!jump_label_unlock:traceoff' >> set_ftrace_filter
# grep jump_label_unlock set_ftrace_filter
#
But the loop in reset_ftrace_filter will try to remove multiple instances
multiple times. If this happens the second time will error and cause the
test to fail.
At each iteration of the loop, check to see if the probe being removed still
exists.

If a function probe in set_ftrace_filter belongs to a module, it will
contain the module name. Like:

But writing:
'!wmi_query_block [wmi]:traceoff' > set_ftrace_filter
will cause an error. We still need to write:
'!wmi_query_block:traceoff' > set_ftrace_filter

test_kmod.sh reported false failure when module not present.
Check test_bpf.ko is present in the path before loading it.
Two cases to be addressed here,
In the development process of test_bpf.c unit testing will be done by
developers by using "insmod $SRC_TREE/lib/test_bpf.ko"
On the other hand testers run full tests by installing modules on device
under test (DUT) and followed by modprobe to insert the modules accordingly.

The tests at tools/testing/selftests/bpf can run in patch mode, e.g.,
make -C tools/testing/selftests/bpf run_tests
With the batch mode, I experimented intermittent test failure of
test_xdp_redirect.sh.
....
selftests: test_xdp_redirect [PASS]
selftests: test_xdp_redirect.sh [PASS]
RTNETLINK answers: File exists
selftests: test_xdp_meta [FAILED]
selftests: test_xdp_meta.sh [FAIL]
....
The following illustrates what caused the failure:
(1). test_xdp_redirect creates veth pairs (veth1,veth11) and
(veth2,veth22), and assign veth11 and veth22 to namespace
ns1 and ns2 respectively.
(2). at the end of test_xdp_redirect test, ns1 and ns2 are
deleted. During this process, the deletion of actual
namespace resources, including deletion of veth1{1} and veth2{2},
is put into a workqueue to be processed asynchronously.
(3). test_xdp_meta tries to create veth pair (veth1, veth2).
The previous veth deletions in step (2) have not finished yet,
and veth1 or veth2 may be still valid in the kernel, thus
causing the failure.
The fix is to explicitly delete the veth pair before test_xdp_redirect
exits. Only one end of veth needs deletion as the kernel will delete
the other end automatically. Also test_xdp_meta is also fixed in
similar manner to avoid future potential issues.
