2019-08-08perf annotate: Fix s390 gap between kernel end and module startThomas Richter3-1/+24
During execution of command 'perf top' the error message: Not enough memory for annotating '__irf_end' symbol!) is emitted from this call sequence: __cmd_top perf_top__mmap_read perf_top__mmap_read_idx perf_event__process_sample hist_entry_iter__add hist_iter__top_callback perf_top__record_precise_ip hist_entry__inc_addr_samples symbol__inc_addr_samples symbol__get_annotation symbol__alloc_hist In this function the size of symbol __irf_end is calculated. The size of a symbol is the difference between its start and end address. When the symbol was read the first time, its start and end was set to: symbol__new: __irf_end 0xe954d0-0xe954d0 which is correct and maps with /proc/kallsyms: root@s8360046:~/linux-4.15.0/tools/perf# fgrep _irf_end /proc/kallsyms 0000000000e954d0 t __irf_end root@s8360046:~/linux-4.15.0/tools/perf# In function symbol__alloc_hist() the end of symbol __irf_end is symbol__alloc_hist sym:__irf_end start:0xe954d0 end:0x3ff80045a8 which is identical with the first module entry in /proc/kallsyms This results in a symbol size of __irf_req for histogram analyses of 70334140059072 bytes and a malloc() for this requested size fails. The root cause of this is function __dso__load_kallsyms() +-> symbols__fixup_end() Function symbols__fixup_end() enlarges the last symbol in the kallsyms map: # fgrep __irf_end /proc/kallsyms 0000000000e954d0 t __irf_end # to the start address of the first module: # cat /proc/kallsyms | sort | egrep ' [tT] ' .... 0000000000e952d0 T __security_initcall_end 0000000000e954d0 T __initramfs_size 0000000000e954d0 t __irf_end 000003ff800045a8 T fc_get_event_number [scsi_transport_fc] 000003ff800045d0 t store_fc_vport_disable [scsi_transport_fc] 000003ff800046a8 T scsi_is_fc_rport [scsi_transport_fc] 000003ff800046d0 t fc_target_setup [scsi_transport_fc] On s390 the kernel is located around memory address 0x200, 0x10000 or 0x100000, depending on linux version. Modules however start some- where around 0x3ff xxxx xxxx. This is different than x86 and produces a large gap for which histogram allocation fails. Fix this by detecting the kernel's last symbol and do no adjustment for it. Introduce a weak function and handle s390 specifics.

2019-08-08perf record: Fix module size on s390Thomas Richter3-3/+16
On s390 the modules loaded in memory have the text segment located after the GOT and Relocation table. This can be seen with this output: [root@m35lp76 perf]# fgrep qeth /proc/modules qeth 151552 1 qeth_l2, Live 0x000003ff800b2000 ... [root@m35lp76 perf]# cat /sys/module/qeth/sections/.text 0x000003ff800b3990 [root@m35lp76 perf]# There is an offset of 0x1990 bytes. The size of the qeth module is 151552 bytes (0x25000 in hex). The location of the GOT/relocation table at the beginning of a module is unique to s390. commit 203d8a4aa6ed ("perf s390: Fix 'start' address of module's map") adjusts the start address of a module in the map structures, but does not adjust the size of the modules. This leads to overlapping of module maps as this example shows: [root@m35lp76 perf] # ./perf report -D 0 0 0xfb0 [0xa0]: PERF_RECORD_MMAP -1/0: [0x3ff800b3990(0x25000) @ 0]: x /lib/modules/.../qeth.ko.xz 0 0 0x1050 [0xb0]: PERF_RECORD_MMAP -1/0: [0x3ff800d85a0(0x8000) @ 0]: x /lib/modules/.../ip6_tables.ko.xz The module qeth.ko has an adjusted start address modified to b3990, but its size is unchanged and the module ends at 0x3ff800d8990. This end address overlaps with the next modules start address of 0x3ff800d85a0. When the size of the leading GOT/Relocation table stored in the beginning of the text segment (0x1990 bytes) is subtracted from module qeth end address, there are no overlaps anymore: 0x3ff800d8990 - 0x1990 = 0x0x3ff800d7000 which is the same as 0x3ff800b2000 + 0x25000 = 0x0x3ff800d7000. To fix this issue, also adjust the modules size in function arch__fix_module_text_start(). Add another function parameter named size and reduce the size of the module when the text segment start address is changed.

2019-08-08perf db-export: Fix thread__exec_comm()Adrian Hunter1-1/+11
Threads synthesized from /proc have comms with a start time of zero, and not marked as "exec". Currently, there can be 2 such comms. The first is created by processing a synthesized fork event and is set to the parent's comm string, and the second by processing a synthesized comm event set to the thread's current comm string. In the absence of an "exec" comm, thread__exec_comm() picks the last (oldest) comm, which, in the case above, is the parent's comm string. For a main thread, that is very probably wrong. Use the second-to-last in that case. This affects only db-export because it is the only user of thread__exec_comm(). Example: $ sudo perf record -a -o pt-a-sleep-1 -e intel_pt//u -- sleep 1 $ sudo chown ahunter pt-a-sleep-1 Before: $ perf script -i pt-a-sleep-1 --itrace=bep -s tools/perf/scripts/python/export-to-sqlite.py pt-a-sleep-1.db branches calls $ sqlite3 -header -column pt-a-sleep-1.db 'select * from comm_threads_view' comm_id command thread_id pid tid ---------- ---------- ---------- ---------- ---------- 1 swapper 1 0 0 2 rcu_sched 2 10 10 3 kthreadd 3 78 78 5 sudo 4 15180 15180 5 sudo 5 15180 15182 7 kworker/4: 6 10335 10335 8 kthreadd 7 55 55 10 systemd 8 865 865 10 systemd 9 865 875 13 perf 10 15181 15181 15 sleep 10 15181 15181 16 kworker/3: 11 14179 14179 17 kthreadd 12 29376 29376 19 systemd 13 746 746 21 systemd 14 401 401 23 systemd 15 879 879 23 systemd 16 879 945 25 kthreadd 17 556 556 27 kworker/u1 18 14136 14136 28 kworker/u1 19 15021 15021 29 kthreadd 20 509 509 31 systemd 21 836 836 31 systemd 22 836 967 33 systemd 23 1148 1148 33 systemd 24 1148 1163 35 kworker/2: 25 17988 17988 36 kworker/0: 26 13478 13478 After: $ perf script -i pt-a-sleep-1 --itrace=bep -s tools/perf/scripts/python/export-to-sqlite.py pt-a-sleep-1b.db branches calls $ sqlite3 -header -column pt-a-sleep-1b.db 'select * from comm_threads_view' comm_id command thread_id pid tid ---------- ---------- ---------- ---------- ---------- 1 swapper 1 0 0 2 rcu_sched 2 10 10 3 kswapd0 3 78 78 4 perf 4 15180 15180 4 perf 5 15180 15182 6 kworker/4: 6 10335 10335 7 kcompactd0 7 55 55 8 accounts-d 8 865 865 8 accounts-d 9 865 875 10 perf 10 15181 15181 12 sleep 10 15181 15181 13 kworker/3: 11 14179 14179 14 kworker/1: 12 29376 29376 15 haveged 13 746 746 16 systemd-jo 14 401 401 17 NetworkMan 15 879 879 17 NetworkMan 16 879 945 19 irq/131-iw 17 556 556 20 kworker/u1 18 14136 14136 21 kworker/u1 19 15021 15021 22 kworker/u1 20 509 509 23 thermald 21 836 836 23 thermald 22 836 967 25 unity-sett 23 1148 1148 25 unity-sett 24 1148 1163 27 kworker/2: 25 17988 17988 28 kworker/0: 26 13478 13478 Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: stable@vger.kernel.org Fixes: 65de51f93ebf ("perf tools: Identify which comms are from exec") Link: http://lkml.kernel.org/r/20190808064823.14846-1-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2019-08-08perf annotate: Fix printing of unaugmented disassembled instructions from BPFArnaldo Carvalho de Melo1-1/+1
The code to disassemble BPF programs uses binutil's disassembling routines, and those use in turn fprintf to print to a memstream FILE, adding a newline at the end of each line, which ends up confusing the TUI routines called from: annotate_browser__write() annotate_line__write() annotate_browser__printf() ui_browser__vprintf() SLsmg_vprintf() The SLsmg_vprintf() function in the slang library gets confused with the terminating newline, so make the disasm_line__parse() function that parses the lines produced by the BPF specific disassembler (that uses binutil's libopcodes) and the lines produced by the objdump based disassembler used for everything else (and that doesn't adds this terminating newline) trim the end of the line in addition of the beginning. This way when disasm_line->ops.raw, i.e. for instructions without a special scnprintf() method, we'll not have that \n getting in the way of filling the screen right after the instruction with spaces to avoid leaving what was on the screen before and thus garbling the annotation screen, breaking scrolling, etc. Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Song Liu <songliubraving@fb.com> Fixes: 6987561c9e86 ("perf annotate: Enable annotation of BPF programs") Link: https://lkml.kernel.org/n/tip-unbr5a5efakobfr6rhxq99ta@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

This selftest was created together with a fix for generic XDP, in commit 297249569932 ("net: fix generic XDP to handle if eth header was mangled"). And was suppose to catch if generic XDP was broken again. The tests are using veth and assumed that veth driver didn't support native driver XDP, thus it used the (ip link set) 'xdp' attach that fell back to generic-XDP. But veth gained native-XDP support in 948d4f214fde ("veth: Add driver XDP"), which caused this test script to use native-XDP.

2019-08-03cgroup: kselftest: relax fs_spec checksChris Down1-2/+1
On my laptop most memcg kselftests were being skipped because it claimed cgroup v2 hierarchy wasn't mounted, but this isn't correct. Instead, it seems current systemd HEAD mounts it with the name "cgroup2" instead of "cgroup": % grep cgroup /proc/mounts cgroup2 /sys/fs/cgroup cgroup2 rw,nosuid,nodev,noexec,relatime,nsdelegate 0 0 I can't think of a reason to need to check fs_spec explicitly since it's arbitrary, so we can just rely on fs_vfstype. After these changes, `make TARGETS=cgroup kselftest` actually runs the cgroup v2 tests in more cases.

2019-07-29perf header: Fix use of unitialized value warningNumfor Mbiziwo-Tiapo1-1/+1
When building our local version of perf with MSAN (Memory Sanitizer) and running the perf record command, MSAN throws a use of uninitialized value warning in "tools/perf/util/util.c:333:6". This warning stems from the "buf" variable being passed into "write". It originated as the variable "ev" with the type union perf_event* defined in the "perf_event__synthesize_attr" function in "tools/perf/util/header.c". In the "perf_event__synthesize_attr" function they allocate space with a malloc call using ev, then go on to only assign some of the member variables before passing "ev" on as a parameter to the "process" function therefore "ev" contains uninitialized memory. Changing the malloc call to zalloc to initialize all the members of "ev" which gets rid of the warning. To reproduce this warning, build perf by running: make -C tools/perf CLANG=1 CC=clang EXTRA_CFLAGS="-fsanitize=memory\ -fsanitize-memory-track-origins" (Additionally, llvm might have to be installed and clang might have to be specified as the compiler - export CC=/usr/bin/clang) then running: tools/perf/perf record -o - ls / | tools/perf/perf --no-pager annotate\ -i - --stdio Please see the cover letter for why false positive warnings may be generated.
