Subject[PATCH v2 0/4] perf: make Perf tool aware of SELinux access control
Date

Changes in v2:
- implemented minor doc and code changes to substitute CAP_SYS_ADMIN
with CAP_PERFMON capability;
- introduced Perf doc file with instructions on how to enable and use
perf_event LSM hooks for mandatory access control to perf_event_open()
syscall;

v1: https://lore.kernel.org/lkml/b8a0669e-36e4-a0e8-fd35-3dbd890d2170@linux.intel.com/

repo: git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git perf/core
sha1: ee097e8ee56f8867cbbf45fe2a06f6b9e660c39c


Extend Perf tool with the check of /sys/fs/selinux/enforce value and notify
in case access to perf_event_open() syscall is restricted by the enforced
SELinux policy settings. See new added security.txt file for exact steps
how the changes look like and how to test the patch set.
