Pull networking fixes from David Miller:
 "Several smallish fixes, I don't think any of this requires another -rc
  but I'll leave that up to you:

   1) Don't leak uninitialzed bytes to userspace in xfrm_user, from Eric
      Dumazet.

   2) Route leak in xfrm_lookup_route(), from Tommi Rantala.

   3) Premature poll() returns in AF_XDP, from Björn Töpel.

   4) devlink leak in netdevsim, from Jakub Kicinski.

   5) Don't BUG_ON in fib_compute_spec_dst, the condition can
      legitimately happen. From Lorenzo Bianconi.

   6) Fix some spectre v1 gadgets in generic socket code, from Jeremy
      Cline.

   7) Don't allow user to bind to out of range multicast groups, from
      Dmitry Safonov with a follow-up by Dmitry Safonov.

   8) Fix metrics leak in fib6_drop_pcpu_from(), from Sabrina Dubroca"
