Description Robin Hack 2015-08-06 04:39:49 EDT
Description of problem:
I just installed rhel7.2 developer workstation, log in and this happen
after some time.

Version-Release number of selected component (if applicable):

How reproducible:
I don't know.

Steps to Reproduce:
1. Log in and leave desktop running

Actual results:
SELinux is preventing /usr/bin/python2.7 from write access on the directory /sys/fs/fuse/connections.

*****  Plugin restorecon (99.5 confidence) suggests   ************************

If you want to fix the label. 
/sys/fs/fuse/connections default label should be sysfs_t.
Then you can run restorecon.
# /sbin/restorecon -v /sys/fs/fuse/connections

*****  Plugin catchall (1.49 confidence) suggests   **************************

If you believe that python2.7 should be allowed write access on the connections directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep rhsmd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Could you find out what FUSE filesystem is mounted on that machine?

# mount
Comment 5 Robin Hack 2015-08-06 05:23:29 EDT
Hi Milos. I belive I can :).

[root@unused-4-169 /]# mount | grep fuse
gvfsd-fuse on /run/user/1000/gvfs type fuse.gvfsd-fuse 

fusectl on /sys/fs/fuse/connections type fusectl (rw,relatime)
