Back ported from F19.

Description of problem: 1) timedatectl set-local-rtc 1 2) AVC alert showed up SELinux is preventing /usr/lib/systemd/systemd-timedated from 'create' accesses on the file .adjtimeXXdfqS. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that systemd-timedated should be allowed create access on the .adjtimeXXdfqS file 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-timedat /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:systemd_timedated_t:s0 Target Context system_u:object_r:adjtime_t:s0 Target Objects .adjtimeXXdfqS [ file ] Source systemd-timedat Source Path /usr/lib/systemd/systemd-timedated Port <Unknown> Host (removed) Source RPM Packages systemd-201-2.fc18.7.x86_64 Target RPM Packages Policy RPM selinux-policy-3.11.1-97.fc18.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.9.4-200.fc18.x86_64 #1 SMP Fri May 24 20:10:49 UTC 2013 x86_64 x86_64 Alert Count 1 First Seen 2013-06-05 20:48:01 CEST Last Seen 2013-06-05 20:48:01 CEST Local ID 34e43459-c012-41af-b7a2-12bc71120bbd Raw Audit Messages type=AVC msg=audit(1370458081.796:341): avc: denied { create } for pid=2732 comm="systemd-timedat" name=".adjtimeXXdfqS" scontext=system_u:system_r:systemd_timedated_t:s0 tcontext=system_u:object_r:adjtime_t:s0 tclass=file type=SYSCALL msg=audit(1370458081.796:341): arch=x86_64 syscall=open success=no exit=EACCES a0=7fdb2a0e4a00 a1=800c2 a2=180 a3=27d3a78eff items=0 ppid=1 pid=2732 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 ses=4294967295 tty=(none) comm=systemd-timedat exe=/usr/lib/systemd/systemd-timedated subj=system_u:system_r:systemd_timedated_t:s0 key=(null) Hash: systemd-timedat,systemd_timedated_t,adjtime_t,file,create audit2allow #============= systemd_timedated_t ============== allow systemd_timedated_t adjtime_t:file create; audit2allow -R require { type systemd_timedated_t; type adjtime_t; class file create; } #============= systemd_timedated_t ============== allow systemd_timedated_t adjtime_t:file create; Additional info: reporter: libreport-2.1.4 hashmarkername: setroubleshoot kernel: 3.9.4-200.fc18.x86_64 type: libreport
