Description John Reiser 2004-08-24 10:46:31 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.2)

Description of problem:
During boot to targeted, permissive mode, the logfile
/var/log/messages gets three avc for portmap.  NFS configuration is
default [doing nothing]: /etc/exports is empty (no exported NFS
directories) and there are no NFS imports (no mounts from other machines).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. boot into targeted, permissive mode with empty /etc/exports and no
NFS imports; but default portmap configuration.

Actual Results:  Aug 24 07:40:41 fc3test1 kernel:
audit(1093358440.882:0): avc:  denied  { read write } for  pid=2396
exe=/sbin/portmap path=/dev/console dev=ramfs ino=806
tcontext=system_u:object_r:unlabeled_t tclass=chr_file
Aug 24 07:40:41 fc3test1 kernel: audit(1093358440.892:0): avc:  denied
 { search } for  pid=2397 exe=/sbin/portmap dev=ramfs ino=805
scontext=user_u:system_r:portmap_t tcontext=system_u:object_r:ramfs_t
Aug 24 07:40:41 fc3test1 kernel: audit(1093358440.897:0): avc:  denied
 { getattr } for  pid=2397 exe=/sbin/portmap path=/dev/null dev=ramfs
ino=807 scontext=user_u:system_r:portmap_t
tcontext=system_u:object_r:unlabeled_t tclass=chr_file

Expected Results:  No complaints.

Looks like you are using /dev/ on a ram file system.  This is not
currently supported.

Comment 2 John Reiser 2004-08-25 18:12:15 EDT
It's the result of default FC3T1 Workstation install, plus all
up2date; I didn't change any configuration setting "manually."  I
agree, it does look like /dev is in ramfs; but that's the way that
FC3T1+up2date set it up, so if it's not supposed to be that way, then
that is a bug.
Comment 3 Daniel Walsh 2004-09-09 14:04:38 EDT
Latest policy should support /dev/ on tmpfs.
Please try selinux-policy-strict-1.17.11-2
