====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Add a workaround to avoid a possible crash if nf_nat and nft_chain_nat are
   compiled built-in and nf_nat fails to register, allowing nft_chain_nat to
   access the incorrect pernetns area. This is crash specific of all built-in
   compilation. From Matias Krause.

2) Revisit conncount GC optimization for confirmed conntracks, skip GC round
   if IPS_ASSURED is set on. This is addressing an issue for corner case
   use case scenario involving locally generated traffic. No crash, just a
   functionality fix. From Fernando F. Mancera.

3) Validate iph->ihl in flowtable IPIP tunnel support, from Lorenzo Bianconi.
   This a sanity check to bounces back malformed IPIP packets to classic
   forwarding path.

4) Kdoc fixes for x_tables.h, from Randy Dunlap.

5) Use info->options so nft_synproxy_tcp_options() stays on the same local
   snapshot, otherwise eval path can observe inconsistent mix of mss and
   timestamps. From Runyu Xiao.

6) Add conntrack_sctp_collision.sh to cover for SCTP INIT collisions.
   From Yi Chen.

7) Do not allow NFPROTO_UNSPEC targets if family is NFPROTO_BRIDGE in
   nft_compat. This allows to use non-sense targets such as xt_nat leading
   to crash. From Florian Westphal.

8) Add a selftest queueing from bridge family. From Florian Westphal.

9) Do not allow to reset a conntrack helper via ctnetlink. This feature
   antedates the creation of the conntrack-tools, and it is not used
   I don't have a usecase for it, I prefer to remove than fixing it.

10) Add deprecation warning for IPv4 only conntrack helpers for PPTP
    and IRC. From Florian Westphal.

11) Store the master tuple in the expectation object and use it,
    otherwise SLAB_TYPESAFE_RCU rules allow to display incorrect
    master tuple information through ctnetlink.

12) Run expectation eviction when inserting an expectation with no
    helper, this is a fix for the nft_ct custom expectation support.

13) Fix nft_ct custom expectation timeouts, userspace provides a
    timeout in milliseconds but kernel assumes this comes in seconds.
    From Florian Westphal.

14) Cap maximum number of expectations per class to 255 expectations
    per master conntrack at helper registration. This is a fix to
    restrict the maximum number of expectations per master conntrack
    which can be a issue for the new lazy GC expectation approach.
