Description Juan Quintela 2015-04-07 09:54:39 UTC
Description of problem:
SELinux is preventing /usr/lib/systemd/systemd-networkd from 'getattr' accesses on the file /proc/sys/net/ipv4/conf/vbr0/forwarding.

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

If you believe that systemd-networkd should be allowed getattr access on the forwarding 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-network /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
