Description Amadeusz Sławiński 2012-01-05 21:51:21 UTC
I noticed that syslog-ng occasionally fails too start, upon closer examination it seems to be related to rlpkg -a -r.
After disabling SELinux and /etc/init.d/syslog-ng start it works till next rlpkg -a -r

From dmesg | grep syslog:
[   24.847443] type=1400 audit(1325798987.159:49): avc:  denied  { read write } for  pid=1954 comm="syslog-ng" name="syslog-ng.persist-" dev=dm-0 ino=3375570 scontext=system_u:system_r:syslogd_t tcontext=system_u:object_r:var_lib_t tclass=file

When running /etc/init.d/syslog-ng start manually (without disabling SELinux):
 * Starting syslog-ng ...
Error creating persistent state file; filename='/var/lib/misc/syslog-ng.persist-', error='Permission denied (13)'
 * start-stop-daemon: failed to start `/usr/sbin/syslog-ng'
 * Failed to start syslog-ng                                              [ !! ]
 * ERROR: syslog-ng failed to start


Reproducible: Always

Steps to Reproduce:
1. rlpkg -a -r
2. reboot
3. syslog-ng doesn't start
Actual Results:  
 * Starting syslog-ng ...
 * start-stop-daemon: failed to start `/usr/sbin/syslog-ng'
 * Failed to start syslog-ng                                              [ !! ]
 * ERROR: syslog-ng failed to start

Expected Results:  
It starts

Comment 1 Amadeusz Sławiński 2012-01-05 22:08:19 UTC
What was I thinking... dmesg | grep syslog with SELinux in permissive mode from running /etc/init.s/syslog-ng start:

Comment 2 Sven Vermeulen (RETIRED) gentoo-dev 2012-01-21 19:41:32 UTC
Can you try:

~# semanage fcontext -a -t syslogd_var_lib_t /var/lib/misc/syslog-ng\.persist

and try again?
Comment 3 Amadeusz Sławiński 2012-01-23 15:20:57 UTC
semanage fcontext -a -t syslogd_var_lib_t /var/lib/misc/syslog-ng\.persist-

does the job (do notice "-" at end)

Will be added in r12 as well
