Description Scott Shambarger 2017-11-19 01:47:22 UTC
Description of problem:
type=AVC msg=audit(11/18/2017 17:37:53.371:1179) : avc:  denied  { nnp_transition } for  pid=5165 comm=(emcached) scontext=system_u:system_r:init_t:s0 tcontext=system_u:system_r:memcached_t:s0 tclass=process2 permissive=0 

        Was caused by:
                Missing type enforcement (TE) allow rule.

                You can use audit2allow to generate a loadable module to allow this access.

Results in memcached crashing on startup:

systemd[1]: memcached.service: Main process exited, code=killed, status=11/SEGV

Adding the following policy allowed memcached to work as expected:

allow init_t memcached_t:process2 nnp_transition;

This is probably related to the new systemd option in memcached.service:

NoNewPrivileges=true

Version-Release number of selected component (if applicable):
selinux-policy-3.13.1-283.14.fc27.noarch
memcached-1.5.1-1.fc27.x86_64
