Add further attributes to filter the trace events from AVC.
Please include sample usage and output in the description.
Im not sure where you want it to be.
In the commit message or in a Documentation/trace/events-avc.rst ?
I was just asking for it in the commit message / patch description. I
don't know what is typical for Documentation/trace.
For example, I just took the patches for a spin, running the
selinux-testsuite under perf like so:
sudo perf record -e avc:selinux_audited -g make test
and then ran:
sudo perf report -g
and a snippet of sample output included:
6.40% 6.40% requested=0x800000 denied=0x800000
audited=0x800000 result=-13 ssid=922 tsid=922
scontext=unconfined_u:unconfined_r:test_binder_mgr_t:s0-s0:c0.c1023
tcontext=unconfined_u:unconfined_r:test_binder_mgr_t:s0-s0:c0.c1023
