Description Bahtiar `kalkin` Gadimov 2013-12-04 11:25:42 UTC
Description of problem:
SELinux is preventing /usr/sbin/prelink from 'read' accesses on the file /usr/lib64/realmd/realmd.

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

If you believe that prelink should be allowed read access on the realmd 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 prelink /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2013-12-04 13:33:42 UTC
Is prelink mislabeled?

ls -lZ /usr/sbin/prelink

restorecon -v /usr/sbin/prelink

Comment 2 Bahtiar `kalkin` Gadimov 2013-12-04 13:47:23 UTC
-> ls -lZ /usr/sbin/prelink
-rwxr-xr-x. root root unconfined_u:object_r:bin_t:s0   /usr/sbin/prelink*
-> restorecon -v /usr/sbin/prelink
restorecon reset /usr/sbin/prelink context unconfined_u:object_r:bin_t:s0->unconfined_u:object_r:prelink_exec_t:s0

Is it just mine system which is broken, or was it delivered mislabeled by Fedora 20?

Comment 3 Daniel Walsh 2013-12-04 14:16:18 UTC
I would think this is just yours.  Not sure how it got mislabeled.  If rpm created the file it should have been labeled correctly.

If it happens to other people, I am sure they will show up soon.
