tools headers uapi: Sync linux/stat.h with the kernel sources

2022-10-25T20:40:48+00:00

To pick the changes from: 825cf206ed510c4a ("statx: add direct I/O alignment information") That add a constant that was manually added to tools/perf/trace/beauty/statx.c, at some point this should move to the shell based automated way.

perf beauty: Make the prctl arg regexp more strict to cope with PR_SET_VMA

2022-02-01T16:03:27+00:00

This new PR_SET_VMA value isn't in sequence with all the other prctl arguments and instead uses a big, 0x prefixed hex number: 0x53564d41 (S V M A). This makes it harder to generate a string table as it would be rather sparse, so make the regexp more stricter to avoid catching those. A followup patch for 'perf trace' to cope with such oddities will be needed, but then its a matter for the next merge window. The next patch will update the prctl.h file to cope with this perf build warning: Warning: Kernel ABI header at 'tools/include/uapi/linux/prctl.h' differs from latest version at 'include/uapi/linux/prctl.h' diff -u tools/include/uapi/linux/prctl.h include/uapi/linux/prctl.h Here is the output of this script: $ tools/perf/trace/beauty/prctl_option.sh static const char *prctl_options[] = { [1] = "SET_PDEATHSIG", [2] = "GET_PDEATHSIG", [3] = "GET_DUMPABLE", [4] = "SET_DUMPABLE", [5] = "GET_UNALIGN", [6] = "SET_UNALIGN", [7] = "GET_KEEPCAPS", [8] = "SET_KEEPCAPS", [9] = "GET_FPEMU", [10] = "SET_FPEMU", [11] = "GET_FPEXC", [12] = "SET_FPEXC", [13] = "GET_TIMING", [14] = "SET_TIMING", [15] = "SET_NAME", [16] = "GET_NAME", [19] = "GET_ENDIAN", [20] = "SET_ENDIAN", [21] = "GET_SECCOMP", [22] = "SET_SECCOMP", [23] = "CAPBSET_READ", [24] = "CAPBSET_DROP", [25] = "GET_TSC", [26] = "SET_TSC", [27] = "GET_SECUREBITS", [28] = "SET_SECUREBITS", [29] = "SET_TIMERSLACK", [30] = "GET_TIMERSLACK", [31] = "TASK_PERF_EVENTS_DISABLE", [32] = "TASK_PERF_EVENTS_ENABLE", [33] = "MCE_KILL", [34] = "MCE_KILL_GET", [35] = "SET_MM", [36] = "SET_CHILD_SUBREAPER", [37] = "GET_CHILD_SUBREAPER", [38] = "SET_NO_NEW_PRIVS", [39] = "GET_NO_NEW_PRIVS", [40] = "GET_TID_ADDRESS", [41] = "SET_THP_DISABLE", [42] = "GET_THP_DISABLE", [43] = "MPX_ENABLE_MANAGEMENT", [44] = "MPX_DISABLE_MANAGEMENT", [45] = "SET_FP_MODE", [46] = "GET_FP_MODE", [47] = "CAP_AMBIENT", [50] = "SVE_SET_VL", [51] = "SVE_GET_VL", [52] = "GET_SPECULATION_CTRL", [53] = "SET_SPECULATION_CTRL", [54] = "PAC_RESET_KEYS", [55] = "SET_TAGGED_ADDR_CTRL", [56] = "GET_TAGGED_ADDR_CTRL", [57] = "SET_IO_FLUSHER", [58] = "GET_IO_FLUSHER", [59] = "SET_SYSCALL_USER_DISPATCH", [60] = "PAC_SET_ENABLED_KEYS", [61] = "PAC_GET_ENABLED_KEYS", [62] = "SCHED_CORE", }; static const char *prctl_set_mm_options[] = { [1] = "START_CODE", [2] = "END_CODE", [3] = "START_DATA", [4] = "END_DATA", [5] = "START_STACK", [6] = "START_BRK", [7] = "BRK", [8] = "ARG_START", [9] = "ARG_END", [10] = "ENV_START", [11] = "ENV_END", [12] = "AUXV", [13] = "EXE_FILE", [14] = "MAP", [15] = "MAP_SIZE", }; $ Cc: Adrian Hunter Cc: Colin Cross Cc: Ian Rogers Cc: Jiri Olsa Cc: Kees Cook Cc: Namhyung Kim Cc: Suren Baghdasaryan Link: https://lore.kernel.org/lkml/YflZqY0rYQ3d1bKt@kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf beauty: Add socket level scnprintf that handles ARCH specific SOL_SOCKET

2021-11-12T13:40:34+00:00

SOL_SOCKET has a different value according to the architecture, some have it as 0xffff while all the others have it as 1, so a simple string array isn't usable, add a scnprintf routine that treats it as a special case, using the array for other values. Signed-off-by: Arnaldo Carvalho de Melo
