[PATCH 00/18] Netfilter updates for net-next

[Pablo Neira Ayuso <pablo@netfilter.org>]

Hi David,

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

1) Use kvfree() helper function from x_tables, from Eric Dumazet.

2) Remove extra timer from the conntrack ecache extension, use a
   workqueue instead to redeliver lost events to userspace instead,
   from Florian Westphal.

3) Removal of the ulog targets for ebtables and iptables. The nflog
   infrastructure superseded this almost 9 years ago, time to get rid
   of this code.

4) Replace the list of loggers by an array now that we can only have
   two possible non-overlapping logger flavours, ie. kernel ring buffer
   and netlink logging.

5) Move Eric Dumazet's log buffer code to nf_log to reuse it from
   all of the supported per-family loggers.

6) Consolidate nf_log_packet() as an unified interface for packet logging.
   After this patch, if the struct nf_loginfo is available, it explicitly
   selects the logger that is used.

7) Move ip and ip6 logging code from xt_LOG to the corresponding
   per-family loggers. Thus, x_tables and nf_tables share the same code
   for packet logging.

8) Add generic ARP packet logger, which is used by nf_tables. The
   format aims to be consistent with the output of xt_LOG.

9) Add generic bridge packet logger. Again, this is used by nf_tables
   and it routes the packets to the real family loggers. As a result,
   we get consistent logging format for the bridge family. The ebt_log
   logging code has been intentionally left in place not to break
   backward compatibility since the logging output differs from xt_LOG.

10) Update nft_log to explicitly request the required family logger when
    needed.

11) Finish nft_log so it supports arp, ip, ip6, bridge and inet families.
    Allowing selection between netlink and kernel buffer ring logging.

12) Several fixes coming after the netfilter core logging changes spotted
    by robots.

13) Use IS_ENABLED() macros whenever possible in the netfilter tree,
    from Duan Jiong.

14) Removal of a couple of unnecessary branch before kfree, from Fabian
    Frederick.

You can pull these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next.git

BTW, I would need that you pull net into net-next after this batch, most
likely we'll have another round of nf_tables updates for net-next
that depend on changes that are available in your net tree.

Thanks a lot!
