Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next

Pull networking changes from David S Miller:

1) Remove the ipv4 routing cache. Now lookups go directly into the FIB
trie and use prebuilt routes cached there.

No more garbage collection, no more rDOS attacks on the routing
cache. Instead we now get predictable and consistent performance,
no matter what the pattern of traffic we service.

This has been almost 2 years in the making. Special thanks to
Julian Anastasov, Eric Dumazet, Steffen Klassert, and others who
have helped along the way.

I'm sure that with a change of this magnitude there will be some
kind of fallout, but such things ought the be simple to fix at this
point. Luckily I'm not European so I'll be around all of August to
fix things :-)

The major stages of this work here are each fronted by a forced
merge commit whose commit message contains a top-level description
of the motivations and implementation issues.

2) Pre-demux of established ipv4 TCP sockets, saves a route demux on
input.

3) TCP SYN/ACK performance tweaks from Eric Dumazet.

4) Add namespace support for netfilter L4 conntrack helpers, from Gao
Feng.

5) Add config mechanism for Energy Efficient Ethernet to ethtool, from
Yuval Mintz.

6) Remove quadratic behavior from /proc/net/unix, from Eric Dumazet.

7) Support for connection tracker helpers in userspace, from Pablo
Neira Ayuso.

8) Allow userspace driven TX load balancing functions in TEAM driver,
from Jiri Pirko.

9) Kill off NLMSG_PUT and RTA_PUT macros, more gross stuff with
embedded gotos.

10) TCP Small Queues, essentially minimize the amount of TCP data queued
up in the packet scheduler layer. Whereas the existing BQL (Byte
Queue Limits) limits the pkt_sched --> netdevice queuing levels,
this controls the TCP --> pkt_sched queueing levels.

From Eric Dumazet.

11) Reduce the number of get_page/put_page ops done on SKB fragments,
from Alexander Duyck.

12) Implement protection against blind resets in TCP (RFC 5961), from
Eric Dumazet.

13) Support the client side of TCP Fast Open, basically the ability to
send data in the SYN exchange, from Yuchung Cheng.

Basically, the sender queues up data with a sendmsg() call using
MSG_FASTOPEN, then they do the connect() which emits the queued up
fastopen data.

14) Avoid all the problems we get into in TCP when timers or PMTU events
hit a locked socket. The TCP Small Queues changes added a
tcp_release_cb() that allows us to queue work up to the
release_sock() caller, and that's what we use here too. From Eric
Dumazet.

15) Zero copy on TX support for TUN driver, from Michael S. Tsirkin.

Merge branch 'metrics_restructure'

This patch series works towards the goal of minimizing the amount
of things that can change in an ipv4 route.

In a regime where the routing cache is removed, route changes will
lead to cloning in the FIB tables or similar.

The largest trigger of route metrics writes, TCP, now has it's own
cache of dynamic metric state. The timewait timestamps are stored
there now as well.

As a result of that, pre-cowing metrics is no longer necessary,
and therefore FLOWI_FLAG_PRECOW_METRICS is removed.

Redirect and PMTU handling is moved back into the ipv4 routes. I'm
sorry for all the headaches trying to do this in the inetpeer has
caused, it was the wrong approach for sure.

Since metrics become read-only for ipv4 we no longer need the inetpeer
hung off of the ipv4 routes either. So those disappear too.

Also, timewait sockets no longer need to hold onto an inetpeer either.

After this series, we still have some details to resolve wrt. PMTU and
redirects for a route-cache-less system:

1) With just the plain route cache removal, PMTU will continue to
work mostly fine. This is because of how the local route users
call down into the PMTU update code with the route they already
hold.

However, if we wish to cache pre-computed routes in fib_info
nexthops (which we want for performance), then we need to add
route cloning for PMTU events.

2) Redirects require more work. First, redirects must be changed to
be handled like PMTU. Wherein we call down into the sockets and
other entities, and then they call back into the routing code with
the route they were using.

So we'll be adding an ->update_nexthop() method alongside
->update_pmtu().

And then, like for PMTU, we'll need cloning support once we start
caching routes in the fib_info nexthops.

But that's it, we can completely pull the trigger and remove the
routing cache with minimal disruptions.

As it is, this patch series alone helps a lot of things. For one,
routing cache entry creation should be a lot faster, because we no
longer do inetpeer lookups (even to check if an entry exists).

This patch series also opens the door for non-DST_HOST ipv4 routes,
because nothing fundamentally cares about rt->rt_dst any more. It
can be removed with the base routing cache removal patch. In fact,
that was the primary goal of this patch series.
