Hello.

Thank you for your report. Do you have SELinux enabled (and in enforcing mode)? Can you see any AVCs related to this issue?

Thanks!

I'm getting the same error while resuming from suspend. The following AVCs seem to be related:

Comment 5 lso 2015-05-05 16:11:18 UTC
SELinux is installed and configured for enforcement.  I also noticed that
the immutable bit is being set for the /etc/resolv.conf file.  Here is the
output.


   root@Adelie:[29]# ls -al resolv.conf*
   -r--r--r--. 1 root root  56 2015-04-26 10:25 resolv.conf
   -rw-r--r--. 1 root root 245 2015-04-25 22:52 resolv.conf.tmp

   root@Adelie:[29]# ls -alZ resolv.conf*
   -r--r--r--. root root system_u:object_r:net_conf_t:s0  resolv.conf
   -rw-r--r--. root root system_u:object_r:net_conf_t:s0  resolv.conf.tmp

   root@Adelie:[34]# lsattr resolv.conf
   ----i--------e-- resolv.conf

   root@Adelie:[35]# chattr -i resolv.conf
   root@Adelie:[36]# lsattr resolv.conf
   -------------e-- resolv.conf

Packages selinux-policy and selinux-policy-targeted are installed.
