What happens when you
restorecon -R -v /var
Nothing much.
# ls -Zd /var
drwxr-xr-x root root system_u:object_r:var_t /var
# restorecon -R -v /var
restorecon reset /var/log/Xorg.0.log context
system_u:object_r:var_log_t->system_u:object_r:xserver_log_t
restorecon reset /var/log/xen-hotplug.log context
system_u:object_r:var_log_t->system_u:object_r:xend_var_log_t
restorecon reset /var/log/Xorg.0.log.old context
system_u:object_r:var_log_t->system_u:object_r:xserver_log_t
lstat(/var/lib/nfs/rpc_pipefs) failed: Permission denied
restorecon reset /var/run/sendmail.pid context
system_u:object_r:var_run_t->system_u:object_r:sendmail_var_run_t
# ls -Zd /var
drwxr-xr-x root root system_u:object_r:var_t /var
And rebooting still results in 450 messages like:
Apr 3 20:25:04 random kernel: audit(1144092277.317:451): avc: denied { search } for
pid=1384 comm="pam_console_app" name="var" dev=hde3 ino=62785
scontext=system_u:system_r:pam_console_t:s0-s0:c0.c255
tcontext=system_u:object_r:file_t:s0 tclass=dir
I've tried booting with the FC5 rescue CD. This shows that the /var
mount point on hde3 still has the wrong context:
sh-3.1# ls -id var
62785 var
sh-3.1# ls -Zd var
drwxr-xr-x root root system_u:object_r:file_t:s0 var
There doesn't seem to be a copy of restorecon on the rescue CD so I
wasn't able to change the context of the mount point.
Why's pan_console_app trying to access /var before it's been mounted
anyway?
