The portmap messages seem unrelated, but I'm seeing on other systems as well:
Nov 10 08:52:25 makani kernel: audit(1131637933.908:3): avc: denied { read }
for pid=2308 comm="portmap" name="nsswitch.conf" dev=hda5 ino=289813
scontext=system_u:system_r:portmap_t tcontext=system_u:object_r:etc_runtime_t
tclass=file
Did some program/script create the /etc/nsswitch.conf file It should have a file context of etc_t on it. restorecon /etc/nsswitch.conf should fix. I would disable cardmgr transition to make it work. setsebool -P cardmgr_disable_trans=1 Cardmgr needs to run MAKEDEV and MAKEDEV is too powerfull, so it doesn't make sense to muck around with the policy and cardmgr is going away in FC5. /etc/nsswitch.conf is installed by cfengine. Looks like it got set back to etc_t at some point. I edited the file, let cfengine replace and stayed at etc_t. Perhaps a relic from some other config? Thanks for the cargmgr boolean. |
