Description Robert Scheck 2015-05-04 15:58:34 UTC
Description of problem:
Right now running tmpwatch on directories being labelled as samba_share_t
or nfs_t leads to AVC denied messages, which might be right in the first
case but it should be possible to allow it via SELinux booleans through -
because we have backups on NFS that are cleaned up with tmpwatch or also
a samba share for temporary files being watched by tmpwatch. Both fails as
of writing due to the too strict SELinux policy.

Version-Release number of selected component (if applicable):
selinux-policy-targeted-3.13.1-23.el7.noarch
tmpwatch-2.11-5.el7.x86_64

How reproducible:
Everytime, label a directory with samba_share_t or nfs_t and run tmpwatch.

Actual results:
No SELinux boolean to allow tmpwatch on samba_share_t or nfs_t.

Expected results:
SELinux boolean to allow tmpwatch on samba_share_t or nfs_t.
