SELinux is preventing /bin/mount from read access on the file /proc/<pid>/mounts.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you want to allow mount to have read access on the mounts file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep /bin/mount /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2010-11-15 16:08:24 UTC
Miroslav, could you add

	ps_process_pattern(mount_t, $1)


To mount_domtrans.

Should take care of this.

Fixed in selinux-policy-3.9.7-13.fc14
