Description Maciek Borzecki 2019-03-29 14:46:01 UTC
Description of problem:

When working on some SELinux enhancements to snapd, I got this:

----
time->Thu Mar 28 15:09:46 2019
type=AVC msg=audit(1553785786.977:906): avc:  denied  { map_create } for  pid=31513 comm="systemd" scontext=system_u:system_r:unconfined_service_t:s0 tcontext=system_u:system_r:unconfined_service_t:s0 tclass=bpf permissive=0
----

Since we already allow map_create for unconfined_t, we should perhaps allow it for unconfined_service_t too.

Version-Release number of selected component (if applicable):

selinux-policy-devel-3.14.2-49.fc29.noarch
