We used libaudit to map ids to syscall names and vice-versa, but that imposes a delay in supporting new syscalls, having to wait for libaudit to get those new syscalls on its tables. To remove that delay, for x86_64 initially, grab a copy of arch/x86/entry/syscalls/syscall_64.tbl and use it to generate those tables. Syscalls currently not available in audit-libs: # trace -e copy_file_range,membarrier,mlock2,pread64,pwrite64,timerfd_create,userfaultfd Error: Invalid syscall copy_file_range, membarrier, mlock2, pread64, pwrite64, timerfd_create, userfaultfd Hint: try 'perf list syscalls:sys_enter_*' Hint: and: 'man syscalls' # With this patch: # trace -e copy_file_range,membarrier,mlock2,pread64,pwrite64,timerfd_create,userfaultfd 8505.733 ( 0.010 ms): gnome-shell/2519 timerfd_create(flags: 524288) = 36 8506.688 ( 0.005 ms): gnome-shell/2519 timerfd_create(flags: 524288) = 40 30023.097 ( 0.025 ms): qemu-system-x8/24629 pwrite64(fd: 18, buf: 0x7f63ae382000, count: 4096, pos: 529592320) = 4096 31268.712 ( 0.028 ms): qemu-system-x8/24629 pwrite64(fd: 18, buf: 0x7f63afd8b000, count: 4096, pos: 2314133504) = 4096 31268.854 ( 0.016 ms): qemu-system-x8/24629 pwrite64(fd: 18, buf: 0x7f63afda2000, count: 4096, pos: 2314137600) = 4096 Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/n/tip-51xfjbxevdsucmnbc4ka5r88@git.kernel.org [ Added make dep for 'prepare' in 'LIBPERF_IN', fix by Wang Nan to fix parallell build ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
