Hi,

please include

commit 6a2a2b3ae0759843b22c929881cc184b00cc63ff

Author: Ani Sinha <[email protected]>
Date:   Mon Sep 8 14:49:59 2014 -0700

net:socket: set msg_namelen to 0 if msg_name is passed as NULL in
msghdr struct from userland.

to 3.14.y and older trees, since it fixes a userspace regression caused by commit dbb490b9 ("net: socket: error on a negative msg_namelen"). The patch applies cleanly to all trees down to 2.6.32.y.

Thanks,
Michal

I'm queuing this for the 3.16 kernel as well. Thanks!

thanks,

Queued up for 3.4. Thansks!

It's still missing from 3.2.y, so cc Ben.

One of the nice things about standards is that there are so many of them.
