2019-07-29tools perf beauty: Fix usbdevfs_ioctl table generator to handle _IOC()Arnaldo Carvalho de Melo
In addition to _IOW() and _IOR(), to handle this case: #define USBDEVFS_CONNINFO_EX(len) _IOC(_IOC_READ, 'U', 32, len) That will happen in the next sync of this header file.

2019-05-28perf trace: Beautify 'sync_file_range' argumentsArnaldo Carvalho de Melo
Use existing beautifiers for the first arg, fd, assigned using the heuristic that looks for syscall arg names and associates SCA_FD with 'fd' named argumes, and wire up the recently introduced sync_file_range flags table generator. Now it should be possible to just use: perf trace -e sync_file_range As root and see all sync_file_range syscalls with its args beautified. Doing a syscall strace like session looking for this syscall, then run postgresql's initdb command: # perf trace -e sync_file_range <SNIP> initdb/1332 sync_file_range(6</var/lib/pgsql/data/global/1260_fsm>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(6</var/lib/pgsql/data/global/1260_fsm>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(7</var/lib/pgsql/data/base/1/2682>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(6</var/lib/pgsql/data/global/1260_fsm>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(7</var/lib/pgsql/data/base/1/2682>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(6</var/lib/pgsql/data/global/1260_fsm>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(4</var/lib/pgsql/data>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(4</var/lib/pgsql/data>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 ^C # Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Amir Goldstein <amir73il@gmail.com> Cc: Brendan Gregg <brendan.d.gregg@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Luis Cláudio Gonçalves <lclaudio@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lkml.kernel.org/n/tip-8tqy34xhpg8gwnaiv74xy93w@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2018-12-18perf trace beauty: Beautify arch_prctl()'s argumentsArnaldo Carvalho de Melo
This actually so far, AFAIK is available only in x86, so the code was put in place with x86 prefixes, in arches where it is not available it will just not be called, so no further mechanisms are needed at this time. Later, when other arches wire this up, we'll just look at the uname (live sessions) or perf_env data in the perf.data header to auto-wire the right beautifier. With this the output is the same as produced by 'strace' when used with the following ~/.perfconfig: # cat ~/.perfconfig [llvm] dump-obj = true [trace] add_events = /home/acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.o show_zeros = yes show_duration = no no_inherit = yes show_timestamp = no show_arg_names = no args_alignment = -40 show_prefix = yes # And, on fedora 29, since the string tables are generated from the kernel sources, we don't know about 0x3001, just like strace: --- /tmp/strace 2018-12-17 11:22:08.707586721 -0300 +++ /tmp/trace 2018-12-18 11:11:32.037512729 -0300 @@ -1,49 +1,49 @@ -arch_prctl(0x3001 /* ARCH_??? */, 0x7ffc8a92dc80) = -1 EINVAL (Invalid argument) +arch_prctl(0x3001 /* ARCH_??? */, 0x7ffe4eb93ae0) = -1 EINVAL (Invalid argument) -arch_prctl(ARCH_SET_FS, 0x7faf6700f540) = 0 +arch_prctl(ARCH_SET_FS, 0x7fb507364540) = 0 And that seems to be related to the CET/Shadow Stack feature, that userland in Fedora 29 (glibc 2.28) are querying the kernel about, that 0x3001 seems to be ARCH_CET_STATUS, I'll check the situation and test with a fedora 29 kernel to see if the other codes are used. A diff that ignores the different pointers for different runs needs to be put in place in the upcoming regression tests comparing 'perf trace's output to strace's.

2018-10-31perf beauty: Add a generator for MAP_ mmap's flag constantsArnaldo Carvalho de Melo
It'll use tools/{arch}/*,include copies of mman.h to generate a table to be used by tools, initially by the 'mmap' beautifiers in 'perf trace', but that could also be used to translate from a string constant to the integer value to be used in a eBPF or tracefs tracepoint filter.
