====================
Netfilter updates for net-next

The following patchset contains Netfilter updates for your net-next
tree, they are:

1) Consolidate GRE protocol tracker using new GRE protocol definitions,
   patches from Gao Feng.

2) Properly parse continuation lines in SIP helper, update allowed
   characters in Call-ID header and allow tabs in SIP headers as
   specified by RFC3261, from Marco Angaroni.

3) Remove useless code in FTP conntrack helper, also from Gao Feng.

4) Add number generation expression for nf_tables, with random and
   incremental generators. This also includes specific offset to add
   to the result, patches from Laura Garcia Liebana. Liping Zhang
   follows with a fix to avoid a race in this new expression.

5) Fix new quota expression inversion logic, added in the previous
   pull request.

6) Missing validation of queue configuration in nft_queue, patch
   from Liping Zhang.

7) Remove unused ctl_table_path, as part of the deprecation of the
   ip_conntrack sysctl interface coming in the previous batch.
   Again from Liping Zhang.

8) Add offset attribute to nft_hash expression, so we can generate
   any output from a specific base offset. Moreover, check for
   possible overflow, patches from Laura Garcia.

9) Allow to invert dynamic set insertion from packet path, to check
   for overflows in case the set is full.

10) Revisit nft_set_pktinfo*() logic from nf_tables to ensure
    proper initialization of layer 4 protocol. Consolidate pktinfo
    structure initialization for bridge and netdev families.

11) Do not inconditionally drop IPv6 packets that we cannot parse
    transport protocol for ip6 and inet families, let the user decide
    on this via ruleset policy.

12) Get rid of gotos in __nf_ct_try_assign_helper().

13) Check for return value in register_netdevice_notifier() and
    nft_register_chain_type(), patches from Gao Feng.

14) Get rid of CONFIG_IP6_NF_IPTABLES dependency in nf_queue
    infrastructure that is common to nf_tables, from Liping Zhang.

15) Disable 'found' and 'searched' stats that are updates from the
    packet hotpath, not very useful these days.

16) Validate maximum value of u32 netlink attributes in nf_tables,
    this introduces nft_parse_u32_check(). From Laura Garcia.

17) Add missing code to integrate nft_queue with maps, patch from
    Liping Zhang. This also includes missing support ranges in
    nft_queue bridge family.

18) Fix check in nft_payload_fast_eval() that ensure that we don't
    go over the skbuff data boundary, from Liping Zhang.

19) Check if transport protocol is set from nf_tables tracing and
    payload expression. Again from Liping Zhang.

20) Use net_get_random_once() whenever possible, from Gao Feng.

21) Replace hardcoded value by sizeof() in xt_helper, from Gao Feng.

22) Remove superfluous check for found element in nft_lookup.

23) Simplify TCPMSS logic to check for minimum MTU, from Gao Feng.

24) Replace double linked list by single linked list in Netfilter
    core hook infrastructure, patchset from Aaron Conole. This
    includes several patches to prepare this update.

25) Fix wrong sequence adjustment of TCP RST with no ACK, from
    Gao Feng.

26) Relax check for direction attribute in nft_ct for layer 3 and 4
    protocol fields, from Liping Zhang.

27) Add new revision for hashlimit to support higher pps of upto 1
    million, from Vishwanath Pai.

28) Evict stale entries in nf_conntrack when reading entries from
    /proc/net/nf_conntrack, from Florian Westphal.

29) Fix transparent match for IPv6 request sockets, from Krisztian
    Kovacs.

30) Add new range expression for nf_tables.

31) Add missing code to support for flags in nft_log. Expose NF_LOG_*
    flags via uapi and use it from the generic logging infrastructure,
    instead of using xt specific definitions, from Liping Zhang.
