Two packets may race to create the same entry in the hashtable,
double check if this packet lost race. This double checking only
happens in the path of the packet that creates the hashtable for
first time.

Note that, with this patch, no packet drops occur if the race happens.

Florian Westphal reported that the removal of the NOTRACK target
(96550501 netfilter: remove xt_NOTRACK) is breaking some existing
setups.

That removal was scheduled for removal since long time ago as
described in Documentation/feature-removal-schedule.txt

What:  xt_NOTRACK
Files: net/netfilter/xt_NOTRACK.c
When:  April 2011
Why:   Superseded by xt_CT

Still, people may have not notice / may have decided to stick to an
old iptables version. I agree with him in that some more conservative
approach by spotting some printk to warn users for some time is less
agressive.

Current iptables 1.4.16.3 already contains the aliasing support
that makes it point to the CT target, so upgrading would fix it.
Still, the policy so far has been to avoid pushing our users to
upgrade.

As a solution, this patch recovers the NOTRACK target inside the CT
target and it now spots a warning.

The problem occurs when iptables constructs the tcp reset packet.
It doesn't initialize the pointer to the tcp header within the skb.
When the skb is passed to the ixgbe driver for transmit, the ixgbe
driver attempts to access the tcp header and crashes.
Currently, other drivers (such as our 1G e1000e or igb drivers) don't
access the tcp header on transmit unless the TSO option is turned on.

Recently I posted commit 3c68198e which made selection of the cookie hmac
algorithm selectable.  This is all well and good, but Linus noted that it
changes the default config:
http://marc.info/?l=linux-netdev&m=135536629004808&w=2

I've modified the sctp Kconfig file to reflect the recommended way of making
this choice, using the thermal driver example specified, and brought the
defaults back into line with the way they were prior to my origional patch

Also, on Linus' suggestion, re-adding ability to select default 'none' hmac
algorithm, so we don't needlessly bloat the kernel by forcing a non-none
default.  This also led me to note that we won't honor the default none
condition properly because of how sctp_net_init is encoded.  Fix that up as
well.

Tested by myself (allbeit fairly quickly).  All configuration combinations seems
to work soundly.

This happens, because sk_clone_lock initializes sk_refcnt to 2, and thus
a single sock_put() is not enough to free the memory. Additionally, things
like xfrm, memcg, cookie_values,... may have been initialized.
We have to free them properly.

This is fixed by forcing a call to tcp_done(), ending up in
inet_csk_destroy_sock, doing the final sock_put(). tcp_done() is necessary,
because it ends up doing all the cleanup on xfrm, memcg, cookie_values,
xfrm,...

Before calling tcp_done, we have to set the socket to SOCK_DEAD, to
force it entering inet_csk_destroy_sock. To avoid the warning in
inet_csk_destroy_sock, inet_num has to be set to 0.
As inet_csk_destroy_sock does a dec on orphan_count, we first have to
increase it.

Calling tcp_done() allows us to remove the calls to
tcp_clear_xmit_timer() and tcp_cleanup_congestion_control().

A similar approach is taken for dccp by calling dccp_done().

This is in the kernel since 093d2823 (tproxy: fix hash locking issue

The current multiqueue API is ambigious which may confuse both user and LSM to
do things correctly:

- Both TUNSETIFF and TUNSETQUEUE could be used to create the queues of a tuntap
  device.
- TUNSETQUEUE were used to disable and enable a specific queue of the
  device. But since the state of tuntap were completely removed from the queue,
  it could be used to attach to another device (there's no such kind of
  requirement currently, and it needs new kind of LSM policy.
- TUNSETQUEUE could be used to attach to a persistent device without any
  queues. This kind of attching bypass the necessary checking during TUNSETIFF
  and may lead unexpected result.

So this patch tries to make a cleaner and simpler API by:

- Only allow TUNSETIFF to create queues.
- TUNSETQUEUE could be only used to disable and enabled the queues of a device,
  and the state of the tuntap device were not detachd from the queues when it
  was disabled, so TUNSETQUEUE could be only used after TUNSETIFF and with the
   same device.

This is done by introducing a list which keeps track of all queues which were
disabled. The queue would be moved between this list and tfiles[] array when it
was enabled/disabled. A pointer of the tun_struct were also introdued to track
the device it belongs to when it was disabled.

After the change, the isolation between management and application could be done
through: TUNSETIFF were only called by management software and TUNSETQUEUE were
only called by application.For LSM/SELinux, the things left is to do proper
check during tun_set_queue() if needed.

This reverts commit f269ae04.

It turns out it causes a very noticeable interactivity regression with
CONFIG_SCHED_AUTOGROUP (test-case: "make -j32" of the kernel in a
terminal window, while scrolling in a browser - the autogrouping means
that the two end up in separate cgroups, and the browser should be
smooth as silk despite the high load).

Says Paul Turner:
 "It seems that the update-throttling on the wake-side is reducing the
  interactive tasks' ability to preempt.  While I suspect the right
  longer term answer here is force these updates only in the
  cross-cgroup case; this is less trivial.  For this release I believe
  the right answer is either going to be a revert or restore the updates
  on the enqueue-side."

Pull first round of SCSI updates from James Bottomley:
 "This patch set includes two large new drivers: mpt3sas (for the next
  gen fusion SAS hardware) and csiostor a FCoE offload driver for the
  Chelsio converged network cards (this includes some net changes which
  I've OK'd with DaveM).

  The rest of the patch is driver updates (qla2xxx, lpfc, hptiop,
  be2iscsi) plus a few assorted updates and bug fixes.

  We also have a Power Management rework in the Upper Layer Drivers
  preparatory to doing ACPI zero power optical devices, but the actual
  enabler is still being worked on.

Pull SPI updates from Grant Likely:
 "Primarily SPI device driver bug fixes, one removal of an old driver,
  and some new tegra support.  There is some core code change too, but
  all in all pretty small stuff.

  The new features to note are:
   - Common code for describing GPIO CS lines in the device tree
   - Remove the SPI_BUFSIZ limitation on spi_write_the_read()
   - core spi ensures bits_per_word is set correctly
   - SPARC can now use SPI"

Merge emailed autofs cleanup/fix patches from Ian Kent

* autofs:
  autofs4 - use simple_empty() for empty directory check
  autofs4 - dont clear DCACHE_NEED_AUTOMOUNT on rootless mount

For direct (and offset) mounts, if an automounted mount is manually
umounted the trigger mount dentry can appear non-empty causing it to
not trigger mounts. This can also happen if there is a file handle
leak in a user space automounting application.

This happens because, when a ioctl control file handle is opened
on the mount, a cursor dentry is created which causes list_empty()
to see the dentry as non-empty. Since there is a case where listing
the directory of these dentrys is needed, the use of dcache_dir_*()
functions for .open() and .release() is needed.

Consequently simple_empty() must be used instead of list_empty()
when checking for an empty directory.

The DCACHE_NEED_AUTOMOUNT flag is cleared on mount and set on expire
for autofs rootless multi-mount dentrys to prevent unnecessary calls
to ->d_automount().

Since DCACHE_MANAGE_TRANSIT is always set on autofs dentrys ->d_managed()
is always called so the check can be done in ->d_manage() without the
need to change the flag. This still avoids unnecessary calls to
->d_automount(), adds negligible overhead and eliminates a seriously
ugly check in the expire code.

Pull Xen updates from Konrad Rzeszutek Wilk:
 - Add necessary infrastructure to make balloon driver work under ARM.
 - Add /dev/xen/privcmd interfaces to work with ARM and PVH.
 - Improve Xen PCIBack wild-card parsing.
 - Add Xen ACPI PAD (Processor Aggregator) support - so can offline/
   online sockets depending on the power consumption.
 - PVHVM + kexec = use an E820_RESV region for the shared region so we
   don't overwrite said region during kexec reboot.
 - Cleanups, compile fixes.

Fix up some trivial conflicts due to the balloon driver now working on
ARM, and there were changes next to the previous work-arounds that are
now gone.
