One comment: #ifdefs around #include is necessary to overcome amazing compile
breakages in NOTRACK-in-netns patch (see below).Signed-off-by: Alexey Dobriyan

Now that dev_net() exists, the usefullness of them is even less. Also they're
a big problem in resolving circular header dependencies necessary for
NOTRACK-in-netns patch. See below.Signed-off-by: Alexey Dobriyan

When a match or target is looked up using xt_find_{match,target},
Xtables will also search the NFPROTO_UNSPEC module list. This allows
for protocol-independent extensions (like xt_time) to be reused from
other components (e.g. arptables, ebtables).Extensions that take different codepaths depending on match->family
or target->family of course cannot use NFPROTO_UNSPEC within the
registration structure (e.g. xt_pkttype).Signed-off-by: Jan Engelhardt

The netfilter subsystem only supports a handful of protocols (much
less than PF_*) and even non-PF protocols like ARP and
pseudo-protocols like PF_BRIDGE. By creating NFPROTO_*, we can earn a
few memory savings on arrays that previously were always PF_MAX-sized
and keep the pseudo-protocols to ourselves.Signed-off-by: Jan Engelhardt

This updates xt_recent to support the IPv6 address family.
The new /proc/net/xt_recent directory must be used for this.
The old proc interface can also be configured out.Signed-off-by: Jan Engelhardt

Like with other modules (such as ipt_state), ipt_recent.h is changed
to forward definitions to (IOW include) xt_recent.h, and xt_recent.c
is changed to use the new constant names.Signed-off-by: Jan Engelhardt

idev has been stored on seq->private. NULL has been stored for global
statistics.The situation is changed with net namespace. We need to store pointer to
struct net and the only place is seq->private. So, we'll have for
/proc/net/dev_snmp6/* and for /proc/net/snmp6 pointers of two different
types stored in the same field.This effectively requires to separate seq_ops of these files.

Simple, comsolidate sockstat6 staff in one place, at the beginning of
the file. Right now sockstat6_seq_open/sockstat6_seq_fops looks like an
intrusion in the middle of snmp6 code.Signed-off-by: Denis V. Lunev

I'm quite sure that if I give this function in its old format
for you to inspect, you start to wonder what is the type of

It all started from me noticing that this urgent check in
tcp_clean_rtx_queue is unnecessarily inside the loop. Then
I took a longer look to it and found out that the users of
urg_mode can trivially do without, well almost, there was
one gotcha.Bonus: those funny people who use urg with >= 2^31 write_seq -
snd_una could now rejoice too (that's the only purpose for the
between being there, otherwise a simple compare would have done
the thing). Not that I assume that the rest of the tcp code
happily lives with such mind-boggling numbers :-). Alas, it
turned out to be impossible to set wmem to such numbers anyway,
yes I really tried a big sendfile after setting some wmem but
nothing happened :-). ...Tcp_wmem is int and so is sk_sndbuf...
So I hacked a bit variable to long and found out that it seems
to work... :-)Signed-off-by: Ilpo Järvinen

Add some packet-split receive hooks.
For one this allows to do NUMA node affine page allocs. Later on these
hooks will be extended to do emergency reserve allocations for
fragments.Signed-off-by: Peter Zijlstra

This makes that ip6_route_net_init() does all of the route init code.
There used to be a race between ip6_route_net_init() and ip6_net_init()
and someone relying on the combined result was left out cold.Signed-off-by: Peter Zijlstra

To be able to use the cached socket reference in the skb during input

qdisc->requeue was planned to universally replace all requeuing code,
but at the top level we never requeue more than one skb, so qdisc->
gso_skb is enough for this. qdisc->requeue would be used on the lower
levels only for one level deep requeuing (like in sch_hfsc) after
finishing all the changes.Signed-off-by: Jarek Poplawski

Jay Cliburn noticed and diagnosed a bug triggered in
dev_gso_skb_destructor() after last change from qdisc->gso_skb
to qdisc->requeue list. Since gso_segmented skbs can't be queued
to another list this patch brings back qdisc->gso_skb for them.Reported-by: Jay Cliburn

This protocol provides some connection handling and negotiated
congestion control. Nokia cellular modems use it for bulk transfers.
It provides packet boundaries (hence SOCK_SEQPACKET). Congestion
control is per packet rather per byte, so we do not re-use the
generic socket memory accounting.Signed-off-by: Rémi Denis-Courmont
