Description Thomas Graf 2013-09-09 13:03:42 UTC
+++ This bug was initially created as a clone of Bug #1002606 +++

Description of problem:
Install openvswitch-1.11.0-1.fc19.x86_64.rpm, start of the openvswitch service will trigger the error.
SELinux is preventing /usr/sbin/ovsdb-server from 'write' accesses on the directory /tmp.

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

If you believe that ovsdb-server should be allowed write access on the tmp directory 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 ovsdb-server /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

We should allow this but openvswitch thould not be writing any thing in /tmp, it should use /run.

Priv apps writing to /tmp is just wrong.

Agreed, we are preparing upstream patches to address this but the 1.11.0 can't be fixed anymore and must still be functional.
