Description Matěj Cepl 2011-03-12 09:10:06 UTC
SELinux is preventing /usr/sbin/wpa_supplicant from 'write' accesses on the netlink_socket Unknown.

Actually I have no idea, how this happened. Just found this in sealert -b list. Yes I am connected to the network via WiFi almost all the time.

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

If you believe that wpa_supplicant should be allowed write access on the Unknown netlink_socket 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 wpa_supplicant /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
