holger@eitzenberger.org 180cf72f56 netfilter: nf_ct_sip: consolidate NAT hook functions
There are currently seven different NAT hooks used in both
nf_conntrack_sip and nf_nat_sip, each of the hooks is exported in
nf_conntrack_sip, then set from the nf_nat_sip NAT helper.

And because each of them is exported there is quite some overhead
introduced due of this.

By introducing nf_nat_sip_hooks I am able to reduce both text/data
somewhat.  For nf_conntrack_sip e. g. I get

        text             data              bss              dec
old    15243             5256               32            20531
new    15010             5192               32            20234

Vitaly Lavrov 1785e8f473 netfiler: ipset: Add net namespace for ipset
This patch adds netns support for ipset.

Major changes were made in ip_set_core.c and ip_set.h.
Global variables are moved to per net namespace.
Added initialization code and the destruction of the network namespace ipset subsystem.
In the prototypes of public functions ip_set_* added parameter "struct net*".

The remaining corrections related to the change prototypes of public functions ip_set_*.

The patch for git://git.netfilter.org/ipset.git commit 6a4ec96c0b8caac5c35474e40e319704d92ca347

Oliver Smith 68b63f08d2 netfilter: ipset: Support comments for ipset entries in the core.
This adds the core support for having comments on ipset entries.

The comments are stored as standard null-terminated strings in
dynamically allocated memory after being passed to the kernel. As a
result of this, code has been added to the generic destroy function to
iterate all extensions and call that extension's destroy task if the set
has that extension activated, and if such a task is defined.

Jozsef Kadlecsik 0f1799ba1a netfilter: ipset: Consistent userspace testing with nomatch flag
The "nomatch" commandline flag should invert the matching at testing,
similarly to the --return-nomatch flag of the "set" match of iptables.
Until now it worked with the elements with "nomatch" flag only. From
now on it works with elements without the flag too, i.e:

 # ipset n test hash:net
 # ipset a test 10.0.0.0/24 nomatch
 # ipset t test 10.0.0.1
 10.0.0.1 is NOT in set test.
 # ipset t test 10.0.0.1 nomatch
 10.0.0.1 is in set test.

 # ipset a test 192.168.0.0/24
 # ipset t test 192.168.0.1
 192.168.0.1 is in set test.
 # ipset t test 192.168.0.1 nomatch
 192.168.0.1 is NOT in set test.

 Before the patch the results were

 ...
 # ipset t test 192.168.0.1
 192.168.0.1 is in set test.
 # ipset t test 192.168.0.1 nomatch
 192.168.0.1 is in set test.

The e{uid,gid} --> {uid,gid} credentials fix conflicted with the
cleanup in net-next to now pass cred structs around.

The be2net driver had a bug fix in 'net' that overlapped with the VLAN
interface changes by Patrick McHardy in net-next.

An IGB conflict existed because in 'net' the build_skb() support was
reverted, and in 'net-next' there was a comment style fix within that
code.

Several batman-adv conflicts were resolved by making sure that all
calls to batadv_is_my_mac() are changed to have a new bat_priv first
argument.

Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO
rewrite in 'net-next', mostly overlapping changes.

Thanks to Stephen Rothwell and Antonio Quartulli for help with several
of these merge resolutions.
