Commit 63233159:
    bridge: Do not unregister all PF_BRIDGE rtnl operations
introduced a bug where a removal of a single bridge from a
multi-bridge system would remove MDB netlink handlers.
The handlers should only be removed once all bridges are gone, but
since we don't keep track of the number of bridge interfaces, it's
simpler to do it when the bridge module is unloaded.  To make it
consistent, move the registration code into module initialization
code path.

====================
The following batch contains Netfilter fixes for 3.8-rc1. They are
a mixture of old bugs that have passed unnoticed (I'll pass these to
stable) and more fresh ones from the previous merge window, they are:

* Fix for MAC address in 6in4 tunnels via NFLOG that results in ulogd
  showing up wrong address, from Bob Hockney.

* Fix a comment in nf_conntrack_ipv6, from Florent Fourcot.

* Fix a leak an error path in ctnetlink while creating an expectation,
  from Jesper Juhl.

* Fix missing ICMP time exceeded in the IPv6 defragmentation code, from
  Haibo Xi.

* Fix inconsistent handling of routing changes in MASQUERADE for the
  new connections case, from Andrew Collins.

* Fix a missing skb_reset_transport in ip[6]t_REJECT that leads to
  crashes in the ixgbe driver (since it seems to access the transport
  header with TSO enabled), from Mukund Jampala.

* Recover obsoleted NOTRACK target by including it into the CT and spot
  a warning via printk about being obsoleted. Many people don't check the
  scheduled to be removal file under Documentation, so we follow some
  less agressive approach to kill this in a year or so. Spotted by Florian
  Westphal, patch from myself.

* Fix race condition in xt_hashlimit that allows to create two or more
  entries, from myself.

* Fix crash if the CT is used due to the recently added facilities to
  consult the dying and unconfirmed conntrack lists, from myself.

The socket calls from vxlan to join/leave multicast group aren't
using the index of the underlying device, as a result the stack uses
the first interface that is up. This results in vxlan being non functional
over a device which isn't the 1st to be up.
Fix this by providing the iflink field to the vxlan instance

In commit 96e0bf4b (tcp: Discard segments that ack data not yet
sent) John Dykstra enforced a check against ack sequences.

In commit 354e4aa3 (tcp: RFC 5961 5.2 Blind Data Injection Attack
Mitigation) I added more safety tests.

But we missed fact that these tests are not performed if ACK bit is
not set.

RFC 793 3.9 mandates TCP should drop a frame without ACK flag set.

" fifth check the ACK field,
      if the ACK bit is off drop the segment and return"

Not doing so permits an attacker to only guess an acceptable sequence
number, evading stronger checks.

Unfortunately with !CONFIG_PAGEFLAGS_EXTENDED, (!PageHead) is false, and
(PageHead) is true, for tail pages.  If this is indeed the intended
behavior, which I doubt because it breaks cache cleaning on some ARM
systems, then the nomenclature is highly problematic.

This patch makes sure PageHead is only true for head pages and PageTail
is only true for tail pages, and neither is true for non-compound pages.

[ This buglet seems ancient - seems to have been introduced back in Apr
  2008 in commit 6a1e7f77: "pageflags: convert to the use of new
  macros".  And the reason nobody noticed is because the PageHead()
  tests are almost all about just sanity-checking, and only used on
  pages that are actual page heads.  The fact that the old code returned
  true for tail pages too was thus not really noticeable.   - Linus ]

batadv_iv_ogm_emit_send_time() attempts to calculates a random integer
in the range of 'orig_interval +- BATADV_JITTER' by the below lines.

        msecs = atomic_read(&bat_priv->orig_interval) - BATADV_JITTER;
        msecs += (random32() % 2 * BATADV_JITTER);

But it actually gets 'orig_interval' or 'orig_interval - BATADV_JITTER'
because '%' and '*' have same precedence and associativity is
left-to-right.

This adds the parentheses at the appropriate position so that it matches
original intension.

e_id is a backwards compatibility field only used for file systems

acl tag field is neither ACL_USER nor ACL_GROUP assigning e_id is
unnecessary.  Remove the assignment so f2fs will build with user

Oleg pointed out that in a pid namespace the sequence.
- pid 1 becomes a zombie
- setns(thepidns), fork,...
- reaping pid 1.
- The injected processes exiting.

Can lead to processes attempting access their child reaper and
instead following a stale pointer.

That waitpid for init can return before all of the processes in
the pid namespace have exited is also unfortunate.

Avoid these problems by disabling the allocation of new pids in a pid
namespace when init dies, instead of when the last process in a pid
namespace is reaped.

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.

Commit f0ed2ce8 ("[media] uvcvideo: Set error_idx properly for

on one of my test machines (there is no sound under KDE 4.9.4 using
pulseaudio and there is a knotify4 process occupying one of the CPU
cores 100% of the time).  Reverting that commit entirely fixes the
problem for me.

However, commit f0ed2ce8 appears to do more than it follows from its
changelog, because the changelog only says about the changes related to
ctrls->error_idx, while the commit additionally changes error codes
returned by various functions in uvc_ctrl.c and uvc_v4l2.c.  It turns
out that the changes of the returned error codes confuse the user spce,
so it is sufficient to revert the part of commit f0ed2ce8 not
mentioned in its changelog to fix the problem.

functions.  The current lm73 driver casts that return value from a s32
type to a s16 type, then converts it to a temperature in celsius.
Because negative temperatures are valid, it is difficult to distinguish
between an error code printed to the response buffer and a negative
temperature recorded by the sensor.

The solution is to evaluate the return value from the i2c functions
before performing any temperature calculations.  If the i2c function did
not succeed, the error code should be passed back through the virtual
file system layer instead of being printed into the response buffer.

Before:

   $ cat /sys/class/hwmon/hwmon0/device/temp1_input
   -46

After:

   $ cat /sys/class/hwmon/hwmon0/device/temp1_input
   cat: read error: No such device or address
