Is this expected? Yes, it is. Please see Bug #1242578. Unfortunately since we don't have better way to get NetworkManager's PID, we call 'pidof NetworkManager' and then send signal to it. increasing severity, since SELinux is blocking basic functionality in dnssec-trigger by not allowing to get PID of NetworkManager commit 48a5464232fe9ff4b06b37fe48bce45e2f9114ec

Description of problem: SELinux is preventing pidof from 'getattr' accesses on the directory /proc/<pid>. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that pidof should be allowed getattr access on the <pid> directory by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep pidof /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:dnssec_trigger_t:s0 Target Context system_u:system_r:sshd_t:s0-s0:c0.c1023 Target Objects /proc/<pid> [ dir ] Source pidof Source Path pidof Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-141.fc23.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.2.0-0.rc6.git0.2.fc23.x86_64 #1 SMP Wed Aug 12 21:39:36 UTC 2015 x86_64 x86_64 Alert Count 1 First Seen 2015-08-25 13:08:59 CEST Last Seen 2015-08-25 13:08:59 CEST Local ID 0869243f-7704-4ffc-807c-0e7d4350b82a Raw Audit Messages type=AVC msg=audit(1440500939.68:1815): avc: denied { getattr } for pid=6508 comm="pidof" path="/proc/12190" dev="proc" ino=1187739 scontext=system_u:system_r:dnssec_trigger_t:s0 tcontext=system_u:system_r:sshd_t:s0-s0:c0.c1023 tclass=dir permissive=0 Hash: pidof,dnssec_trigger_t,sshd_t,dir,getattr Version-Release number of selected component: selinux-policy-3.13.1-141.fc23.noarch Additional info: reporter: libreport-2.6.2 hashmarkername: setroubleshoot kernel: 4.2.0-0.rc6.git0.2.fc23.x86_64 type: libreport
