Netfilter updates for next-net (part 2)
The following patchset contains Netfilter updates for net-next. This
patchset includes updates for nf_tables, removal of
CONFIG_NETFILTER_DEBUG and a new mode for xt_hashlimit. More
specifically, they:
1) Add new rate match mode for hashlimit, this introduces a new revision
for this match. The idea is to stop matching packets until ratelimit
criteria stands true. Patch from Vishwanath Pai.
2) Add ->select_ops indirection to nf_tables named objects, so we can
choose between different flavours of the same object type, patch from
Pablo M. Bermudo.
3) Shorter function names in nft_limit, basically:
s/nft_limit_pkt_bytes/nft_limit_bytes, also from Pablo M. Bermudo.
4) Add new stateful limit named object type, this allows us to create
limit policies that you can identify via name, also from Pablo.
5) Remove unused hooknum parameter in conntrack ->packet indirection.
From Florian Westphal.
6) Patches to remove CONFIG_NETFILTER_DEBUG and macros such as
IP_NF_ASSERT and IP_NF_ASSERT. From Varsha Rao.
7) Add nf_tables_updchain() helper function and use it from
nf_tables_newchain() to make it more maintainable. Similarly,
add nf_tables_addchain() and use it too.
8) Add new netlink NLM_F_NONREC flag, this flag should only be used for
deletion requests, specifically, to support non-recursive deletion.
Based on what we discussed during NFWS'17 in Faro.
9) Use NLM_F_NONREC from table and sets in nf_tables.
10) Support for recursive chain deletion. Table and set deletion
commands come with an implicit content flush on deletion, while
chains do not. This patch addresses this inconsistency by adding
the code to perform recursive chain deletions. This also comes with
the bits to deal with the new NLM_F_NONREC netlink flag.
