perf probe-event: Ensure probe event nsinfo is always cleared

2025-12-03T19:07:23Z

Move nsinfo__zput from cleanup_perf_probe_events to clear_perf_probe_event so it is always executed. Clean up clear_perf_probe_events to not call nsinfo__zput and use the pev variable to avoid repeated array accesses. Signed-off-by: Ian Rogers Signed-off-by: Namhyung Kim

perf machine: Explicitly pass in host perf_env

2025-07-25T17:37:57Z

When creating a machine for the host explicitly pass in a scoped perf_env. This removes a use of the global perf_env. Signed-off-by: Ian Rogers Link: https://lore.kernel.org/r/20250724163302.596743-17-irogers@google.com Signed-off-by: Namhyung Kim

perf build-id: Ensure struct build_id is empty before use

2025-07-25T17:37:55Z

If a build ID is read then not all code paths may ensure it is empty before use. Initialize the build_id to be zero-ed unless there is clear initialization such as a call to build_id__init.

perf probe: Rename err label

2025-01-14T17:57:19Z

Rename err to out to avoid confusion because buf is still supposed to be freed in non error cases.

perf probe: Fix uninitialized variable

2024-12-12T05:40:46Z

Since the linked fixes: commit, err is returned uninitialized due to the removal of "return 0". Initialize err to fix it. This fixes the following intermittent test failure on release builds: $ perf test "testsuite_probe" ... -- [ FAIL ] -- perf_probe :: test_invalid_options :: mutually exclusive options :: -L foo -V bar (output regexp parsing) Regexp not found: \"Error: switch .+ cannot be used with switch .+\" ...

perf probe: Replace unacceptable characters when generating event name

2024-12-10T18:41:10Z

Replace unacceptable characters with '_' when generating event name from the probing function name. This is not for a C program. For the a C program, it will continue to remove suffixes. Note that this language checking depends on the debuginfo. So without the debuginfo, perf probe will always replaces unacceptable characters with '_'. For example. $ ./perf probe -x cro3 -D \"cro3::cmd::servo::run_show\" p:probe_cro3/cro3_cmd_servo_run_show /work/cro3/target/x86_64-unknown-linux-gnu/debug/cro3:0x197530 $ ./perf probe -x /work/go/example/outyet/main -D 'main.(*Server).poll' p:probe_main/main_Server_poll /work/go/example/outyet/main:0x353040 Signed-off-by: Masami Hiramatsu Cc: Alexander Lobakin Cc: Dima Kogan Cc: Ian Rogers Cc: Ingo Molnar Cc: Namhyung Kim Cc: Peter Zijlstra Cc: Przemek Kitszel Link: https://lore.kernel.org/r/173145728160.2747044.18089011235495186810.stgit@mhiramat.roam.corp.google.com [ Removed some extra tabs in the new struct fields ] Signed-off-by: Arnaldo Carvalho de Melo

perf: Remove unused del_perf_probe_events()

2024-11-16T20:07:31Z

del_perf_probe_events() last use was removed by commit 3d6dfae889174340 ("perf parse-events: Remove BPF event support") Remove it. It was the last user of probe_file__del_events(), so remove it as well.
