   1) Fix gro_cells leak in xfrm layer, from Li RongQing.

   2) BPF selftests change RLIMIT_MEMLOCK blindly, don't do that.  From
      Eric Dumazet.

   3) AF_XDP calls synchronize_net() under RCU lock, fix from Björn
      Töpel.

   4) Out of bounds packet access in _decode_session6(), from Alexei
      Starovoitov.

   5) Several ethtool bugs, where we copy a struct into the kernel twice
      and our validations of the values in the first copy can be
      invalidated by the second copy due to asynchronous updates to the
      memory by the user.  From Wenwen Wang.

   6) Missing netlink attribute validation in cls_api, from Davide
      Caratti.

   7) LLC SAP sockets neet to be SOCK_RCU FREE, from Cong Wang.

   8) rxrpc operates on wrong kvec, from Yue Haibing.

   9) A regression was introduced by the disassosciation of route
      neighbour references in rt6_probe(), causing probe for
      neighbourless routes to not be properly rate limited.  Fix from
      Sabrina Dubroca.

   10) Unsafe RCU locking in tipc, from Tung Nguyen.

   11) Use after free in inet6_mc_check(), from Eric Dumazet.

   12) PMTU from icmp packets should update the SCTP transport pathmtu,
       from Xin Long.

   13) Missing peer put on error in rxrpc, from David Howells.

   14) Fix pedit in nfp driver, from Pieter Jansen van Vuuren.

   15) Fix overflowing shift statement in qla3xxx driver, from Nathan
       Chancellor.

   16) Fix Spectre v1 in ptp code, from Gustavo A. R. Silva.

   17) udp6_unicast_rcv_skb() interprets udpv6_queue_rcv_skb() return
       value in an inverted manner, fix from Paolo Abeni.

   18) Fix missed unresolved entries in ipmr dumps, from Nikolay
       Aleksandrov.

   19) Fix NAPI handling under high load, we can completely miss events
       when NAPI has to loop more than one time in a cycle.  From Heiner
       Kallweit."
