Do you know what you were doing when this happened? Does this happen at loginout? Killing a session? Yes, this was happening during login if I remember correctly. Luckily, I haven't seen it happen in a week or two. (That being said, I don't log in/out very often.) I guess systemd-logind is killing all sessions and perhaps cleaning up semaphores. Description of problem: Upon upgrading from F20 to F21, with DNF, screen got locked by GNOME. But after logind got upgraded I couldn't login back to my existing session.

When systemd_logind kills sessions it also destroys semaphores

Description of problem: SELinux is preventing /usr/lib/systemd/systemd-logind from 'destroy' accesses on the semaphore Unknown. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that systemd-logind should be allowed destroy access on the Unknown sem 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 systemd-logind /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:systemd_logind_t:s0 Target Context unconfined_u:unconfined_r:mozilla_plugin_t:s0-s0:c 0.c1023 Target Objects Unknown [ sem ] Source systemd-logind Source Path /usr/lib/systemd/systemd-logind Port <Unknown> Host (removed) Source RPM Packages systemd-215-3.fc21.x86_64 Target RPM Packages Policy RPM selinux-policy-3.13.1-64.fc21.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.16.0-0.rc4.git3.1.fc21.x86_64 #1 SMP Fri Jul 11 17:13:44 UTC 2014 x86_64 x86_64 Alert Count 1 First Seen 2014-07-17 18:17:54 PDT Last Seen 2014-07-17 18:17:54 PDT Local ID 201e0d7d-a6a7-425b-a302-e0d1e68c9612 Raw Audit Messages type=AVC msg=audit(1405646274.916:1608): avc: denied { destroy } for pid=915 comm="systemd-logind" key=1881097292 scontext=system_u:system_r:systemd_logind_t:s0 tcontext=unconfined_u:unconfined_r:mozilla_plugin_t:s0-s0:c0.c1023 tclass=sem permissive=0 type=SYSCALL msg=audit(1405646274.916:1608): arch=x86_64 syscall=semctl success=no exit=EACCES a0=c800d a1=0 a2=0 a3=7fffd60d91f0 items=0 ppid=1 pid=915 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=systemd-logind exe=/usr/lib/systemd/systemd-logind subj=system_u:system_r:systemd_logind_t:s0 key=(null) Hash: systemd-logind,systemd_logind_t,mozilla_plugin_t,sem,destroy Version-Release number of selected component: selinux-policy-3.13.1-64.fc21.noarch Additional info: reporter: libreport-2.2.3 hashmarkername: setroubleshoot kernel: 3.16.0-0.rc4.git3.1.fc21.x86_64 type: libreport Potential duplicate: bug 1116520
