Pull networking updates from David Miller:

1) The addition of nftables. No longer will we need protocol aware
firewall filtering modules, it can all live in userspace.

At the core of nftables is a, for lack of a better term, virtual
machine that executes byte codes to inspect packet or metadata
(arriving interface index, etc.) and make verdict decisions.

Besides support for loading packet contents and comparing them, the
interpreter supports lookups in various datastructures as
fundamental operations. For example sets are supports, and
therefore one could create a set of whitelist IP address entries
which have ACCEPT verdicts attached to them, and use the appropriate
byte codes to do such lookups.

Since the interpreted code is composed in userspace, userspace can
do things like optimize things before giving it to the kernel.

Another major improvement is the capability of atomically updating
portions of the ruleset. In the existing netfilter implementation,
one has to update the entire rule set in order to make a change and
this is very expensive.

Userspace tools exist to create nftables rules using existing
netfilter rule sets, but both kernel implementations will need to
co-exist for quite some time as we transition from the old to the
new stuff.

Kudos to Patrick McHardy, Pablo Neira Ayuso, and others who have
worked so hard on this.

2) Daniel Borkmann and Hannes Frederic Sowa made several improvements
to our pseudo-random number generator, mostly used for things like
UDP port randomization and netfitler, amongst other things.

In particular the taus88 generater is updated to taus113, and test
cases are added.

3) Support 64-bit rates in HTB and TBF schedulers, from Eric Dumazet
and Yang Yingliang.

4) Add support for new 577xx tigon3 chips to tg3 driver, from Nithin
Sujir.

5) Fix two fatal flaws in TCP dynamic right sizing, from Eric Dumazet,
Neal Cardwell, and Yuchung Cheng.

6) Allow IP_TOS and IP_TTL to be specified in sendmsg() ancillary
control message data, much like other socket option attributes.
From Francesco Fusco.

7) Allow applications to specify a cap on the rate computed
automatically by the kernel for pacing flows, via a new
SO_MAX_PACING_RATE socket option. From Eric Dumazet.

8) Make the initial autotuned send buffer sizing in TCP more closely
reflect actual needs, from Eric Dumazet.

9) Currently early socket demux only happens for TCP sockets, but we
can do it for connected UDP sockets too. Implementation from Shawn
Bohrer.

10) Refactor inet socket demux with the goal of improving hash demux
performance for listening sockets. With the main goals being able
to use RCU lookups on even request sockets, and eliminating the
listening lock contention. From Eric Dumazet.

11) The bonding layer has many demuxes in it's fast path, and an RCU
conversion was started back in 3.11, several changes here extend the
RCU usage to even more locations. From Ding Tianhong and Wang
Yufen, based upon suggestions by Nikolay Aleksandrov and Veaceslav
Falico.

12) Allow stackability of segmentation offloads to, in particular, allow
segmentation offloading over tunnels. From Eric Dumazet.

13) Significantly improve the handling of secret keys we input into the
various hash functions in the inet hashtables, TCP fast open, as
well as syncookies. From Hannes Frederic Sowa. The key fundamental
operation is "net_get_random_once()" which uses static keys.

Hannes even extended this to ipv4/ipv6 fragmentation handling and
our generic flow dissector.

14) The generic driver layer takes care now to set the driver data to
NULL on device removal, so it's no longer necessary for drivers to
explicitly set it to NULL any more. Many drivers have been cleaned
up in this way, from Jingoo Han.

15) Add a BPF based packet scheduler classifier, from Daniel Borkmann.

16) Improve CRC32 interfaces and generic SKB checksum iterators so that
SCTP's checksumming can more cleanly be handled. Also from Daniel
Borkmann.

17) Add a new PMTU discovery mode, IP_PMTUDISC_INTERFACE, which forces
using the interface MTU value. This helps avoid PMTU attacks,
particularly on DNS servers. From Hannes Frederic Sowa.

18) Use generic XPS for transmit queue steering rather than internal
(re-)implementation in virtio-net. From Jason Wang.

Merge branch 'huawei_cdc_ncm'

Bjørn Mork says:

====================
The huawei_cdc_ncm driver.

Enrico has been kind enough to let me repost his driver with the changes
requested by Oliver Neukum during the last review of this series.

The changes I have made from Enricos original v5 series to this version
are:

v6:
- fix to avoid corrupting drvstate->pmcount
- fix error return value from huawei_cdc_ncm_suspend()
- drop redundant testing for subdriver->suspend during resume
- broke a few lines to keep within the 80 columns recommendation
- rebased on top of current net-next

Enrico's orginal introduction to the v5 series follows below. It explains
the background much better than I can.

Bjørn

[quote Enrico Mioso]

So this is a new, revised, edition of the huawei_cdc_ncm.c driver, which
supports devices resembling the NCM standard, but using it also as a mean
to encapsulate other protocols, as is the case for the Huawei E3131 and
E3251 modem devices.
Some precisations are needed however - and I encourage discussion on this: and
that's why I'm sending this message with a broader CC.
Merging those patches might change:
- the way Modem Manager interacts with those devices
- some regressions might be possible if there are some unknown firmware
variants around (Franko?)

First of all: I observed the behaviours of two devices.
Huawei E3131: this device doesn't accept NDIS setup requests unless they're
sent via the embedded AT channel exposed by this driver.
So actually we gain funcionality in this case!

The second case, is the Huawei E3251: which works with standard NCM driver,
still exposing an AT embedded channel. Whith this patch set applied, you gain
some funcionality, loosing the ability to catch standard NCM events for now.
The device will work in both ways with no problems, but this has to be
acknowledged and discussed. Might be we can develop this driver further to
change this, when more devices are tested.

We where thinking Huawei changed their interfaces on new devices - but probably
this driver only works around a nice firmware bug present in E3131, which
prevented the modem from being used in NDIS mode.

I think committing this is definitely wortth-while, since it will allow for
more Huawei devices to be used without serial connection. Some devices like the
E3251 also, reports some status information only via the embedded AT channel,
at least in my case.
Note: I'm not subscribed to any list except the Modem Manager's one, so please
CC me, thanks!!
