[PATCH 00/12] Netfilter/IPVS fixes for net

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

Hi David,

The following patchset contains Netfilter/IPVS fixes for your net tree,
they are:

1) When using IPVS in direct-routing mode, normal traffic from the LVS
   host to a back-end server is sometimes incorrectly NATed on the way
   back into the LVS host. Patch to fix this from Julian Anastasov.

2) Calm down clang compilation warning in ctnetlink due to type
   mismatch, from Matthias Kaehlcke.

3) Do not re-setup NAT for conntracks that are already confirmed, this
   is fixing a problem that was introduced in the previous nf-next batch.
   Patch from Liping Zhang.

4) Do not allow conntrack helper removal from userspace cthelper
   infrastructure if already in used. This comes with an initial patch
   to introduce nf_conntrack_helper_put() that is required by this fix.
   From Liping Zhang.

5) Zero the pad when copying data to userspace, otherwise iptables fails
   to remove rules. This is a follow up on the patchset that sorts out
   the internal match/target structure pointer leak to userspace. Patch
   from the same author, Willem de Bruijn. This also comes with a build
   failure when CONFIG_COMPAT is not on, coming in the last patch of
   this series.

6) SYNPROXY crashes with conntrack entries that are created via
   ctnetlink, more specifically via conntrackd state sync. Patch from
   Eric Leblond.

7) RCU safe iteration on set element dumping in nf_tables, from
   Liping Zhang.

8) Missing sanitization of immediate date for the bitwise and cmp
   expressions in nf_tables.

9) Refcounting logic for chain and objects from set elements does not
   integrate into the nf_tables 2-phase commit protocol.

10) Missing sanitization of target verdict in ebtables arpreply target,
    from Gao Feng.
