2013-07-08perf stat: Avoid sending SIGTERM to random processesStephane Eranian1-1/+22
This patch fixes a problem with perf stat whereby on termination it may send a SIGTERM signal to random processes on systems with high PID recycling. I got some actual bug reports on this. There is race between the SIGCHLD and sig_atexit() handlers. This patch addresses this problem by clearing child_pid in the SIGCHLD handler.

2013-07-08perf tools: Include termios.h explicitlyJoonsoo Kim1-1/+1
Building perf for android fails because it can't find the definition of struct winsize. This definition is in termios.h, so I add this header to util.h to solve the problem. It is missed by commit '2c803e52' which moves get_term_dimensions() from builtin-top.c to util.c, but missed to move termios.h header.

Jiri reported hanging perf tests on latest acme's perf/core and bisected it to 87f303a9f: [jolsa@krava2 perf]$ cat /proc/sys/kernel/perf_event_paranoid 1 [jolsa@krava2 perf]$ ./perf record -C 0 kill Error: You may not have permission to collect %sstats. Consider tweaking /proc/sys/kernel/perf_event_paranoid: -1 - Not paranoid at all 0 - Disallow raw tracepoint access for unpriv 1 - Disallow cpu events for unpriv 2 - Disallow kernel profiling for unpriv Need to let default handling kickin for workload process.

2013-05-29perf tests: Fix exclude_guest|exclude_host checking for attr testsJiri Olsa2-4/+4
We have a one of the event open fallback case in __perf_evsel__open where we zero exclude_guest|exclude_host fields. This means there's no way for attr tests to find out what's the right value for those fields, so we need to check for both 0 and 1. Luckily we still have other event parsing tests for those fields.
