I got this when upgrading from selinux-policy-3.9.7-25.fc14.noarch selinux-policy-targeted-3.9.7-25.fc14.noarch to selinux-policy-3.9.7-28.fc14.noarch selinux-policy-targeted-3.9.7-28.fc14.noarch for testing bug 673224 (but on another machine) Why does this have a weird MCS label? Were you playing with MCS Labels? unconfined_u:object_r:gnome_home_t:s0:c293,c554 Or did something happen with sandbox of libvirt? what does id -Z Show? I might have had the mls policy installed on this machine, but I haven't actively used it. Should I look for wrong labels in the filesystem or old rules in the SE db? [root@dev-mk ~]# id -Z unconfined_u:unconfined_r:unconfined_t:s0 (It would be nice if it showed the exact filename instead of just "SELinux Management Tool". But tracing that to system-config-selinux didn't reveal anything...) Hmm. Yes, there is something strange with my system-config-selinux. I get the following when I start it. I don't know what to look for, but I will try a relabel-on-boot.
SELinux is preventing /usr/bin/python from unlink access on the file SELinux Management Tool.
***** Plugin catchall (100. confidence) suggests ***************************
If you believe that python should be allowed unlink access on the SELinux Management Tool 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 /usr/share/syst /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

It seems like a relabel-on-boot fixed these problems. Does that from your POV solve this problem? It looks to me like an upgrade problem caused by 3.9.7-28 or some other recent updates. No the problem was you had a gnome_home_t file on your system with a weird MCS label. Looked like something created by sandbox, although I do not know why. The SELinux Management Tool file had a wrong label on it. Probably running restorecon on this file would have solved your problem. Reopen if it happens again. |
