2014-04-30perf x86: Fix perf to use non-executable stack, againMathias Krause2-1/+11
arch/x86/tests/regs_load.S is missing the linker note about the stack requirements, therefore making the linker fall back to an executable stack. As this object gets linked against the final perf binary, it'll needlessly end up with an executable stack. Fix this by adding the appropriate linker note. Also add a global linker flag to prevent future regressions, as suggested by Jiri. This way perf won't get an executable stack even if we fail to add the .GNU-stack linker note to future assembler files. Though, doing so might create regressions the other way around, when (statically) linking against libraries needing an executable stack. But, apparently, regressing in that direction is wanted as it is an indicator of poor code quality -- or just missing linker notes.

2014-04-30perf machine: Search for modules in %s/lib/modules/%sRichard Yao1-4/+12
Modules installed outside of the kernel's build system should go into "%s/lib/modules/%s/extra", but at present, perf will only look at them when they are in "%s/lib/modules/%s/kernel". Lets encourage good citizenship by relaxing this requirement to "%s/lib/modules/%s". This way open source modules that are out-of-tree have no incentive to start populating a directory reserved for in-kernel modules and I can stop hex-editing my system's perf binary when profiling OSS out-of-tree modules. Feedback from Namhyung Kim correctly revealed that the hex-edits that I had been doing meant that perf was also traversing the build and source symlinks in %s/lib/modules/%s. That is undesireable, so we explicitly exclude them from traversal with a minor tweak to the traversal routine.

2014-04-23tools lib traceevent: Fix memory leak in pretty_print()Steven Rostedt1-0/+1
Commit 12e55569a244 "tools lib traceevent: Use helper trace-seq in print functions like kernel does" added a extra trace_seq helper to process string arguments like the kernel does it. But the difference between the kernel and the userspace library is that the kernel's trace_seq structure has a static allocated buffer. The userspace one has a dynamically allocated one. It requires a trace_seq_destroy(), otherwise it produces a nasty memory leak.

The return value for pevent_filter_match() is suppose to return FILTER_NONE if the event doesn't have a filter, and FILTER_NOEXIST if there is no filter at all. But the change 41e12e580a7 "tools lib traceevent: Refactor pevent_filter_match() to get rid of die()" replaced the return value with PEVENT_ERRNO__* values and added "backward compatibility" macros that used the old names. Unfortunately, the NOEXIST and NONE macros were swapped, and this broke users that use the old return names.

2014-04-20perf tools: Improve error reportingAdrien BAK2-2/+9
In the current version, when using perf record, if something goes wrong in tools/perf/builtin-record.c:375 session = perf_session__new(file, false, NULL); The error message: "Not enough memory for reading per file header" is issued. This error message seems to be outdated and is not very helpful. This patch proposes to replace this error message by "Perf session creation failed" I believe this issue has been brought to lkml: https://lkml.org/lkml/2014/2/24/458 although this patch only tackles a (small) part of the issue. Additionnaly, this patch improves error reporting in tools/perf/util/data.c open_file_write. Currently, if the call to open fails, the user is unaware of it. This patch logs the error, before returning the error code to the caller.

2014-04-20perf kvm: Fix 'Min time' counting in report commandAlexander Yarygin1-0/+1
Every event in the perf-kvm has a 'stats' structure, which contains max/min/average/etc times of handling this event. The problem is that the 'perf-kvm stat report' command always shows that 'min time' is 0us for every event. Example: # perf kvm stat report Analyze events for all VCPUs: VM-EXIT Samples Samples% Time% Min Time Max Time Avg time [..] 0xB2 MSCH 12 0.07% 0.00% 0us 8us 7.31us ( +- 2.11% ) 0xB2 CHSC 12 0.07% 0.00% 0us 18us 9.39us ( +- 9.49% ) 0xB2 STPX 8 0.05% 0.00% 0us 2us 1.88us ( +- 7.18% ) 0xB2 STSI 7 0.04% 0.00% 0us 44us 16.49us ( +- 38.20% ) [..] This happens because the 'stats' structure is not initialized and stats->min equals to 0. Lets initialize the structure for every event after its allocation using init_stats() function. This initializes stats->min to -1 and makes 'Min time' statistics counting work: # perf kvm stat report Analyze events for all VCPUs: VM-EXIT Samples Samples% Time% Min Time Max Time Avg time [..] 0xB2 MSCH 12 0.07% 0.00% 6us 8us 7.31us ( +- 2.11% ) 0xB2 CHSC 12 0.07% 0.00% 7us 18us 9.39us ( +- 9.49% ) 0xB2 STPX 8 0.05% 0.00% 1us 2us 1.88us ( +- 7.18% ) 0xB2 STSI 7 0.04% 0.00% 1us 44us 16.49us ( +- 38.20% ) [..] Signed-off-by: Alexander Yarygin <yarygin@linux.vnet.ibm.com> Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Reviewed-by: David Ahern <dsahern@gmail.com> Link: http://lkml.kernel.org/r/1397053319-2130-3-git-send-email-borntraeger@de.ibm.com [ Fixing the perf examples changelog output ] Signed-off-by: Jiri Olsa <jolsa@redhat.com>

2014-04-14perf probe: Use dwarf_getcfi_elf() instead of dwarf_getcfi()Namhyung Kim1-1/+1
The dwarf_getcfi() only checks .debug_frame section for CFI, but as most binaries only have .eh_frame it'd return NULL and it makes some variables inaccessible. Using dwarf_getcfi_elf (along with dwarf_getelf()) allows to show and add probe to more variables.

2014-04-14perf probe: Fix to handle errors in line_range searchingMasami Hiramatsu1-3/+4
As Namhyung reported(https://lkml.org/lkml/2014/4/1/89), current perf-probe -L option doesn't handle errors in line-range searching correctly. It causes a SEGV if an error occured in the line-range searching. ---- $ perf probe -x ./perf -v -L map__load Open Debuginfo file: /home/namhyung/project/linux/tools/perf/perf fname: util/map.c, lineno:153 New line range: 153 to 2147483647 path: (null) Segmentation fault (core dumped) ---- This is because line_range_inline_cb() ignores errors from find_line_range_by_line() which means that lr->path is already freed on the error path in find_line_range_by_line(). As a result, get_real_path() accesses the lr->path and it causes a NULL pointer exception. This fixes line_range_inline_cb() to handle the error correctly, and report it to the caller. Anyway, this just fixes a possible SEGV bug, Namhyung's patch is also required.

2014-04-14perf probe: Fix --line option behaviorNamhyung Kim1-2/+4
The commit 5a62257a3ddd1 ("perf probe: Replace line_list with intlist") replaced line_list to intlist but it has a problem that if a same line was added again, it'd return -EEXIST rather than 1. Since line_range_walk_cb() only checks the result being negative, it resulted in failure or segfault sometimes.

2014-04-08tools/vm/page-types.c: page-cache sniffing featureKonstantin Khlebnikov1-18/+152
After this patch 'page-types' can walk over a file's mappings and analyze populated page cache pages mostly without disturbing its state. It maps chunk of file, marks VMA as MADV_RANDOM to turn off readahead, pokes VMA via mincore() to determine cached pages, triggers page-fault only for them, and finally gathers information via pagemap/kpageflags. Before unmap it marks VMA as MADV_SEQUENTIAL for ignoring reference bits. usage: page-types -f <path> If <path> is directory it will analyse all files in all subdirectories. Symlinks are not followed as well as mount points. Hardlinks aren't handled, they'll be dumped as many times as they are found. Recursive walk brings all dentries into dcache and populates page cache of block-devices aka 'Buffers'. Probably it's worth to add ioctl for dumping file page cache as array of PFNs as a replacement for this hackish juggling with mmap/madvise/mincore/pagemap. Also recursive walk could be replaced with dumping cached inodes via some ioctl or debugfs interface followed by openning them via open_by_handle_at, this would fix hardlinks handling and unneeded population of dcache and buffers. This interface might be used as data source for constructing readahead plans and for background optimizations of actively used files. collateral changes: + fix 64-bit LFS: define _FILE_OFFSET_BITS instead of _LARGEFILE64_SOURCE + replace lseek + read with single pread + make show_page_range() reusable after flush usage example: ~/src/linux/tools/vm$ sudo ./page-types -L -f page-types foffset offset flags page-types Inode: 2229277 Size: 89065 (22 pages) Modify: Tue Feb 25 12:00:59 2014 (162 seconds ago) Access: Tue Feb 25 12:01:00 2014 (161 seconds ago) 0 3cbf3b __RU_lA____M________________________ 1 38946a __RU_lA____M________________________ 2 1a3cec __RU_lA____M________________________ 3 1a8321 __RU_lA____M________________________ 4 3af7cc __RU_lA____M________________________ 5 1ed532 __RU_lA_____________________________ 6 2e436a __RU_lA_____________________________ 7 29a35e ___U_lA_____________________________ 8 2de86e ___U_lA_____________________________ 9 3bdfb4 ___U_lA_____________________________ 10 3cd8a3 ___U_lA_____________________________ 11 2afa50 ___U_lA_____________________________ 12 2534c2 ___U_lA_____________________________ 13 1b7a40 ___U_lA_____________________________ 14 17b0be ___U_lA_____________________________ 15 392b0c ___U_lA_____________________________ 16 3ba46a __RU_lA_____________________________ 17 397dc8 ___U_lA_____________________________ 18 1f2a36 ___U_lA_____________________________ 19 21fd30 __RU_lA_____________________________ 20 2c35ba __RU_l______________________________ 21 20f181 __RU_l______________________________ flags page-count MB symbolic-flags long-symbolic-flags 0x000000000000002c 2 0 __RU_l______________________________ referenced,uptodate,lru 0x0000000000000068 11 0 ___U_lA_____________________________ uptodate,lru,active 0x000000000000006c 4 0 __RU_lA_____________________________ referenced,uptodate,lru,active 0x000000000000086c 5 0 __RU_lA____M________________________ referenced,uptodate,lru,active,mmap total 22 0 ~/src/linux/tools/vm$ sudo ./page-types -f / flags page-count MB symbolic-flags long-symbolic-flags 0x0000000000000028 21761 85 ___U_l______________________________ uptodate,lru 0x000000000000002c 127279 497 __RU_l______________________________ referenced,uptodate,lru 0x0000000000000068 74160 289 ___U_lA_____________________________ uptodate,lru,active 0x000000000000006c 84469 329 __RU_lA_____________________________ referenced,uptodate,lru,active 0x000000000000007c 1 0 __RUDlA_____________________________ referenced,uptodate,dirty,lru,active 0x0000000000000228 370 1 ___U_l___I__________________________ uptodate,lru,reclaim 0x0000000000000828 49 0 ___U_l_____M________________________ uptodate,lru,mmap 0x000000000000082c 126 0 __RU_l_____M________________________ referenced,uptodate,lru,mmap 0x0000000000000868 137 0 ___U_lA____M________________________ uptodate,lru,active,mmap 0x000000000000086c 12890 50 __RU_lA____M________________________ referenced,uptodate,lru,active,mmap total 321242 1254 Signed-off-by: Konstantin Khlebnikov <koct9i@gmail.com> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Fengguang Wu <fengguang.wu@intel.com> Cc: Borislav Petkov <bp@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
