ipv4: Early TCP socket demux.
Input packet processing for local sockets involves two major demuxes.
One for the route and one for the socket.
But we can optimize this down to one demux for certain kinds of local
sockets.
Currently we only do this for established TCP sockets, but it could
at least in theory be expanded to other kinds of connections.
If a TCP socket is established then it's identity is fully specified.
This means that whatever input route was used during the three-way
handshake must work equally well for the rest of the connection since
the keys will not change.
Once we move to established state, we cache the receive packet's input
route to use later.
Like the existing cached route in sk->sk_dst_cache used for output
packets, we have to check for route invalidations using dst->obsolete
and dst->ops->check().
Early demux occurs outside of a socket locked section, so when a route
invalidation occurs we defer the fixup of sk->sk_rx_dst until we are
actually inside of established state packet processing and thus have
the socket locked.

net: qmi_wwan: bind to both control and data interface
Always bind to control interface regardless of whether
it is a shared interface or not.
A QMI/wwan function is required to provide both a control
interface (QMI) and a data interface (wwan). All devices
supported by this driver do so. But the vendors may
choose to use different USB descriptor layouts, and some
vendors even allow the same device to present different
layouts.
Most of these devices use a USB descriptor layout with a
single USB interface for both control and data. But some
split control and data into two interfaces, bound together
by a CDC Union descriptor on the control interface. Before
the cdc-wdm subdriver support was added, this split was
used to let cdc-wdm drive the QMI control interface and
qmi_wwan drive the wwna data interface.
This split driver model has a number of issues:
- qmi_wwan must match on the data interface descriptor,
which often are indistiguishable from data interfaces
belonging to other CDC (like) functions like ACM
- supporting a single QMI/wwan function requires adding
the device to two drivers
- syncronizing the probes among a number of drivers, to
ensure selecting the correct driver, is difficult unless
all drivers match on the same interface
This patch resolves these problems by using the same
probing mechanism as cdc-ether for devices with a two-
interface USB descriptor layout. This makes the driver
behave consistently, supporting both the control and data
part of the QMI/wwan function, regardless of the USB
descriptors.

core separation from socket and many clean ups and fixed all

====================
The following patchset provides fixes for issues that were recently introduced
by my new cthelper infrastructure. They have been spotted by Randy Dunlap,
Andrew Morton and Dan Carpenter.
The patches provide:
* compilation fixes if CONFIG_NF_CONNTRACK is disabled: I moved all the
conntrack code from nfnetlink_queue.c to nfnetlink_queue_ct.c to avoid
peppering the entire code with lots of ifdefs. I needed to rename
nfnetlink_queue.c to nfnetlink_queue_core.c to get it working with the
Makefile tweaks I've added.
* fix NULL pointer dereference via ctnetlink while trying to change the helper
for an existing conntrack entry. I don't find any reasonable use case for
changing the helper from one to another in run-time. Thus, now ctnetlink
returns -EOPNOTSUPP for this operation.
* fix possible out-of-bound zeroing of the conntrack extension area due to
the helper automatic assignation routine.

netfilter: nf_ct_helper: disable automatic helper re-assignment of different type
This patch modifies __nf_ct_try_assign_helper in a way that invalidates support
for the following scenario:
1) attach the helper A for first time when the conntrack is created
2) attach new (different) helper B due to changes the reply tuple caused by NAT
eg. port redirection from TCP/21 to TCP/5060 with both FTP and SIP helpers
loaded, which seems to be a quite unorthodox scenario.
I can provide a more elaborated patch to support this scenario but explicit
helper attachment provides a better solution for this since now the use can
attach the helpers consistently, without relying on the automatic helper
lookup magic.

netfilter: ctnetlink: fix NULL dereference while trying to change helper
The patch

Smatch complaint:
net/netfilter/nf_conntrack_netlink.c:1231 ctnetlink_change_helper()
error: we previously assumed 'help->helper' could be null (see line 1228)
This NULL dereference can be triggered with the following sequence:
1) attach the helper for first time when the conntrack is created.
2) remove the helper module or detach the helper from the conntrack
via ctnetlink.
3) attach helper again (the same or different one, no matter) to the
that existing conntrack again via ctnetlink.
This patch fixes the problem by removing the use case that allows you
to re-assign again a helper for one conntrack entry via ctnetlink since
I cannot find any practical use for it.

netfilter: add user-space connection tracking helper infrastructure
There are good reasons to supports helpers in user-space instead:
* Rapid connection tracking helper development, as developing code
in user-space is usually faster.
* Reliability: A buggy helper does not crash the kernel. Moreover,
we can monitor the helper process and restart it in case of problems.
* Security: Avoid complex string matching and mangling in kernel-space
running in privileged mode. Going further, we can even think about
running user-space helpers as a non-root process.
* Extensibility: It allows the development of very specific helpers (most
likely non-standard proprietary protocols) that are very likely not to be
accepted for mainline inclusion in the form of kernel-space connection
tracking helpers.
This patch adds the infrastructure to allow the implementation of
user-space conntrack helpers by means of the new nfnetlink subsystem
`nfnetlink_cthelper' and the existing queueing infrastructure
(nfnetlink_queue).
I had to add the new hook NF_IP6_PRI_CONNTRACK_HELPER to register
ipv[4|6]_helper which results from splitting ipv[4|6]_confirm into
two pieces. This change is required not to break NAT sequence
adjustment and conntrack confirmation for traffic that is enqueued
to our user-space conntrack helpers.
Basic operation, in a few steps:
1) Register user-space helper by means of `nfct':
nfct helper add ftp inet tcp
[ It must be a valid existing helper supported by conntrack-tools ]
2) Add rules to enable the FTP user-space helper which is
used to track traffic going to TCP port 21.
For locally generated packets:
iptables -I OUTPUT -t raw -p tcp --dport 21 -j CT --helper ftp
For non-locally generated packets:
iptables -I PREROUTING -t raw -p tcp --dport 21 -j CT --helper ftp
3) Run the test conntrackd in helper mode (see example files under
doc/helper/conntrackd.conf
conntrackd
4) Generate FTP traffic going, if everything is OK, then conntrackd
should create expectations (you can check that with `conntrack':
conntrack -E expect
[NEW] 301 proto=6 src=192.168.1.136 dst=130.89.148.12 sport=0 dport=54037 mask-src=255.255.255.255 mask-dst=255.255.255.255 sport=0 dport=65535 master-src=192.168.1.136 master-dst=130.89.148.12 sport=57127 dport=21 class=0 helper=ftp

This confirms that our test helper is receiving packets including the
conntrack information, and adding expectations in kernel-space.
The user-space helper can also store its private tracking information
in the conntrack structure in the kernel via the CTA_HELP_INFO. The
kernel will consider this a binary blob whose layout is unknown. This
information will be included in the information that is transfered
to user-space via glue code that integrates nfnetlink_queue and
ctnetlink.

netfilter: nf_ct_helper: allocate 16 bytes for the helper and policy names
This patch modifies the struct nf_conntrack_helper to allocate
the room for the helper name. The maximum length is 16 bytes
(this was already introduced in 2.6.24).
For the maximum length for expectation policy names, I have
also selected 16 bytes.
This patch is required by the follow-up patch to support
user-space connection tracking helpers.

Revert "ipv6: Prevent access to uninitialized fib_table_hash via /proc/net/ipv6_route"
This reverts commit
2a0c451ade8e1783c5d453948289e4a978d417c9.
It causes crashes, because now ip6_null_entry is used before
it is initialized.

ipv6: Fix types of ip6_update_pmtu().
The mtu should be a __be32, not the mark.

Conflicts:
net/ipv6/route.c
This deals with a merge conflict between the net-next addition of the
inetpeer network namespace ops, and Thomas Graf's bug fix in
2a0c451ade8e1783c5d453948289e4a978d417c9 which makes sure we don't
register /proc/net/ipv6_route before it is actually safe to do so.
