Description franco santini 2011-10-29 18:43:23 UTC
SELinux is preventing /bin/systemd-tmpfiles from 'unlink' accesses on the sock_file plasma-desktopGh1800.slave-socket.

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

If you believe that systemd-tmpfiles should be allowed unlink access on the plasma-desktopGh1800.slave-socket sock_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 systemd-tmpfile /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2011-10-31 09:55:19 UTC
Did you move this sock file from /home to /tmp directory?

Comment 2 Daniel Walsh 2011-10-31 14:45:43 UTC
We should really never have a sock_file labeled as a user_home_dir_t.  Any idea how this sock_file got created?

Comment 3 franco santini 2011-10-31 17:05:40 UTC
(In reply to comment #1)
> Did you move this sock file from /home to /tmp directory?

I didn't move any file from /home to /tmp. Actualy file  /tmp/systemd_tmpfiles exists with selinux context system_u:object_r:systemd_tmpfiles_exec_t:s0

Comment 4 Daniel Walsh 2011-10-31 18:15:35 UTC
find /tmp -name plasma-desktopGh1800.slave-socket
or

find /var/tmp  -name plasma-desktopGh1800.slave-socket

This seems to be something to do with kde.

Comment 5 franco santini 2011-10-31 19:14:52 UTC
No such file in either directory or elsewhere in filesystem.
Also yum list and google give me nothing!

Comment 6 Daniel Walsh 2011-10-31 19:22:01 UTC
Ok, lets act like this never happened and reopen if it happens again.
