Hi,

please include

commit 6a2a2b3ae0759843b22c929881cc184b00cc63ff

    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
