[PATCH 0/2] net: sock_diag fixes

Hi Dave,

this small series fixes an exploitable bug in sock_diag. An unprivileged
user can send us a netlink message resulting in an out-of-bounds access
that allows userland to take over control while in kernel mode.

The first patch fixes the bug and should be pushed to stable. The second
one is an attempt to cleanup the sock_diag_handlers[] access mess in
__sock_diag_rcv_msg.

Please apply!

  sock_diag: Fix out-of-bounds access to sock_diag_handlers[]
  sock_diag: Simplify sock_diag_handlers[] handling in
    __sock_diag_rcv_msg
