Description Thomas Haller 2016-08-30 16:13:21 UTC

Some buggy drivers either
 - signal success on the netlink message to change the MAC address, but the
   address only actually change the address a moment later.
 - fail the netlink command with ENFILE but the address actually changes.

See for example upstream https://bugzilla.gnome.org/show_bug.cgi?id=770456 or bug 1371478.

this is fixed upstream with
  https://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=e109f870670e7503047309358cf97287ebd18d56
  https://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=091620e76592349ae3efee08faed881ce1a2495b 


These workaround should be backported to rhel-7.3

Comment 4 Thomas Haller 2016-09-08 19:14:36 UTC

The fix so far is not sufficient.

Needs another patch from upstream.
