Willem de Bruijn 538d6cdb9f packet: validate msg_namelen in send directly
[ Upstream commit 486efdc8f6 ]

Packet sockets in datagram mode take a destination address. Verify its
length before passing to dev_hard_header.

Prior to 2.6.14-rc3, the send code ignored sll_halen. This is
established behavior. Directly compare msg_namelen to dev->addr_len.

Change v1->v2: initialize addr in all paths

Fixes: 6b8d95f179 ("packet: validate address length if non-zero")
