Subject: [PATCH 00/23] nf_tables updates for net-next
Hi David,
The following patchset contains the following nf_tables updates,
mostly updates from Patrick McHardy, they are:
* Add the "inet" table and filter chain type for this new netfilter
family: NFPROTO_INET. This special table/chain allows IPv4 and IPv6
rules, this should help to simplify the burden in the administration
of dual stack firewalls. This also includes several patches to prepare
the infrastructure for this new table and a new meta extension to
match the layer 3 and 4 protocol numbers, from Patrick McHardy.
* Load both IPv4 and IPv6 conntrack modules in nft_ct if the rule is used
in NFPROTO_INET, as we don't certainly know which one would be used,
also from Patrick McHardy.
* Do not allow to delete a table that contains sets, otherwise these
sets become orphan, from Patrick McHardy.
* Hold a reference to the corresponding nf_tables family module when
creating a table of that family type, to avoid the module deletion
when in use, from Patrick McHardy.
* Update chain counters before setting the chain policy to ensure that
we don't leave the chain in inconsistent state in case of errors (aka.
restore chain atomicity). This also fixes a possible leak if it fails
to allocate the chain counters if no counters are passed to be restored,
from Patrick McHardy.
* Don't check for overflows in the table counter if we are just renaming
a chain, from Patrick McHardy.
* Replay the netlink request after dropping the nfnl lock to load the
module that supports provides a chain type, from Patrick.
* Fix chain type module references, from Patrick.
* Several cleanups, function renames, constification and code
refactorizations also from Patrick McHardy.
* Add support to set the connmark, this can be used to set it based on
the meta mark (similar feature to -j CONNMARK --restore), from
Kristian Evensen.
* A couple of fixes to the recently added meta/set support and nft_reject,
and fix missing chain type unregistration if we fail to register our
the family table/filter chain type, from myself.
