First, here's getsebool -a | grep -i nfs
cobbler_use_nfs --> off
ftpd_use_nfs --> off
git_cgi_use_nfs --> off
git_system_use_nfs --> off
httpd_use_nfs --> on
ksmtuned_use_nfs --> off
mpd_use_nfs --> off
nfs_export_all_ro --> on
nfs_export_all_rw --> on
nfsd_anon_write --> off
polipo_use_nfs --> off
samba_share_nfs --> off
sanlock_use_nfs --> off
sge_use_nfs --> off
use_nfs_home_dirs --> on
virt_use_nfs --> off
xen_use_nfs --> off
I've got several - here's three:
type=AVC msg=audit(1375711978.360:34383): avc: denied { read } for
pid=32095 comm="mplayer" name="2013-08-05" dev="0:38"
ino=29229135
scontext=system_u:system_r:zoneminder_t:s0
tcontext=system_u:object_r:nfs_t:s0 tclass=dir
Where exactly is this directory "2013-08-05"?
You might be able to find it with the find command: find / -inum
29229135
But yes you would need to add rules to conditionally allow this in
theory (create a boolean zoneminder_use_nfs)
This one is even more fun: it doesn't think bash should be
allowed to
execute mplayer (if I've got the sealert and the audit.log entry matched
up....)
type=AVC msg=audit(1375711977.280:34380): avc: denied { execute } for
pid=32095 comm="mplayer" path="/usr/bin/mplayer" dev="sda3"
ino=793612
scontext=system_u:system_r:zoneminder_t:s0
tcontext=system_u:object_r:mplayer_exec_t:s0 tclass=file
That one looks strange because it seems that mplayer executes itself. In
theory you can use audit2allow to allow this.
Is this what you needed?
