New SELinux Denials on Fedora 22
Description
Squid isn't starting on our fedora 22 pulp-smash install due to selinux denials. :(
# grep -a squid /var/log/audit/audit.log | audit2allow
#============= squid_t ==============
allow squid_t squid_exec_t:file execmod;
allow squid_t tmpfs_t:file { read write getattr open };

I can't tell if these failures are related to our config, or if squid itself has had a regression in fedora 22.

At least the failures related to /dev/shm/squid-cf__metadata.shm have been reported upstream recently, but against fedora 23:
https://bugzilla.redhat.com/show_bug.cgi?id=1331574
This has me thinking that this isn't a pulp problem, but I'd like a little more evidence.

...and here's the execmod issue:

- Status changed from NEW to CLOSED - WONTFIX
- Assignee set to semyers
- OS set to Fedora 22
- Tags SELinux added
I've opened an issue against fedora specifically for fedora 22, found here: https://bugzilla.redhat.com/show_bug.cgi?id=1334928
In the meantime, you can adjust your selinux policy as-needed to get squid working:
# grep squid /var/log/audit/audit.log | audit2allow -M squid
# semodule -i squid.pp
Since there's really nothing we can do for fedora 22 at this time, I'm closing this issue.

set selinux to permissive on fedora 22
