| |
Hi Oleg,
I've been running some tests on my seccomp series, and in one of the tests on v4.20-rc2, I noticed,
[ RUN ] global.syscall_restart seccomp_bpf.c:2784:global.syscall_restart:Expected getpid() (1492) == info._sifields._kill.si_pid (0) global.syscall_restart: Test failed at step #22
which seems unrelated to my series (the kernel was stock v4.20 with my patches on top).
I've been running a lot of tests, and only seen this once, so it seems like a fairly rare race. I tried to look through the code but didn't see anything obvious. Thoughts?
Tycho
