Squid fails to restart due to an AVC reading /var/run/squid.pid: time->Sat Dec 14 17:54:31 2013 type=SYSCALL msg=audit(1387043671.678:8259): arch=40000003 syscall=5 success=no exit=-13 a0=b9367440 a1=8000 a2=1b6 a3=b942b780 items=0 ppid=1 pid=4950 auid=4294967295 uid=23 gid=23 euid=0 suid=0 fsuid=0 egid=23 sgid=23 fsgid=23 ses=4294967295 tty=(none) comm="squid" exe="/usr/sbin/squid" subj=system_u:system_r:squid_t:s0 key=(null) type=AVC msg=audit(1387043671.678:8259): avc: denied { read } for pid=4950 comm="squid" name="squid.pid" dev="tmpfs" ino=20196 scontext=system_u:system_r:squid_t:s0 tcontext=system_u:object_r:init_var_run_t:s0 tclass=file
Did you run squid by hand? Please execute # restorecon -R -v /var/run/squid.pid to fix the labeling and reopen if this happens again.
I hadn't knowingly started it by hand, no. I had upgraded to F20 on Friday, then on Saturday there was a squid update pushed and when yum installed it and tried to restart squid the restart failed. Labelling seems to be right now anyway: gosford [~] % ls -Z /var/run/squid.pid -rw-r--r--. root squid system_u:object_r:squid_var_run_t:s0 /var/run/squid.pid gosford [~] % sudo restorecon -R -v /var/run/squid.pid [sudo] password for tom: gosford [~] % ls -Z /var/run/squid.pid -rw-r--r--. root squid system_u:object_r:squid_var_run_t:s0 /var/run/squid.pid and indeed doing a "systemctl restart squid" works so it looks like it has worked itself out.
Ok, please reopen if this happens again. Thank you.
