At least no in-kernel CardBus-capable PCI driver makes use of the CIS
access functions. Therefore, it seems sensible to remove this unused
code, and cleanup cardbus.c a lot.

During a suspend/resume cycle, an user may change the card in the
PCMCIA/CardBus slot. The pcmcia_core can at least look at the
socket state to check whether it is the same.

For PCMCIA devices, move the detection and handling of such a
change to ds.c.

For CardBus devices, the PCI hotplug interface doesn't offer a "rescan"
facility which also _removes_ devices no longer to be found behind a
bridge. Therefore, remove and re-add all devices unconditionally.

In pccard_validate_cis(), validate the card CIS, not the CIS cache.
Also, destroy the CIS cache if pccard_validate_cis fails.

Furthermore, do not remove the fake CIS in destroy_cis_cache() but

inotify will WARN() if it finds that the idr and the fsnotify internals
somehow got out of sync.  It was only supposed to do this once but due
to this stupid bug it would warn every single time a problem was
detected.

Since commit 7e790dd5 ("inotify: fix
error paths in inotify_update_watch") inotify changed the manor in which
it gave watch descriptors back to userspace.  Previous to this commit
inotify acted like the following:

  inotify_add_watch(X, Y, Z) = 1
  inotify_rm_watch(X, 1);
  inotify_add_watch(X, Y, Z) = 2

but after this patch inotify would return watch descriptors like so:

  inotify_add_watch(X, Y, Z) = 1
  inotify_rm_watch(X, 1);
  inotify_add_watch(X, Y, Z) = 1

which I saw as equivalent to opening an fd where

  open(file) = 1;
  close(1);
  open(file) = 1;

seemed perfectly reasonable.  The issue is that quite a bit of userspace
apparently relies on the behavior in which watch descriptors will not be
quickly reused.  KDE relies on it, I know some selinux packages rely on
it, and I have heard complaints from other random sources such as debian
bug 558981.

Although the man page implies what we do is ok, we broke userspace so
this patch almost reverts us to the old behavior.  It is still slightly
racey and I have patches that would fix that, but they are rather large
and this will fix it for all real world cases.  The race is as follows:

 - task1 creates a watch and blocks in idr_new_watch() before it updates
   the hint.
 - task2 creates a watch and updates the hint.
 - task1 updates the hint with it's older wd
 - task removes the watch created by task2
 - task adds a new watch and will reuse the wd originally given to task2

it requires moving some locking around the hint (last_wd) but this should
solve it for the real world and be -stable safe.

As a side effect this patch papers over a bug in the lib/idr code which
is causing a large number WARN's to pop on people's system and many
reports in kerneloops.org.  I'm working on the root cause of that idr
bug seperately but this should make inotify immune to that issue.

This fixes CERT-FI FICORA #341748

Discovered by Olli Jarva and Tuomo Untinen from the CROSS
project at Codenomicon Ltd.

Just like in CVE-2007-4567, we can't rely upon skb_dst() being
non-NULL at this point.  We fixed that in commit
e76b2b25 ("[IPV6]: Do no rely on
skb->dst before it is assigned.")

However commit 483a47d2 ("ipv6: added
net argument to IP6_INC_STATS_BH") put a new version of the same bug
into this function.

Complicating analysis further, this bug can only trigger when network
namespaces are enabled in the build.  When namespaces are turned off,
the dev_net() does not evaluate it's argument, so the dereference
would not occur.

So, for a long time, namespaces couldn't be turned on unless SYSFS was
disabled.  Therefore, this code has largely been disabled except by
people turning it on explicitly for namespace development.

There are some tg3 devices that require the driver to post new rx
buffers in smaller increments.  Commit
4361935a, "tg3: Consider
rx_std_prod_idx a hw mailbox" changed how the driver tracks the rx
producer ring updates, but it does not make any special considerations
for the above-mentioned devices.  For those devices, it is possible for
the driver to hit the special case path, which updates the hardware
mailbox register but skips updating the shadow software mailbox member.
If the special case path represents the final mailbox update for this
ISR iteration, the hardware and software mailbox values will be out of
sync.  Ultimately, this will cause the driver to use a stale mailbox
value on the next iteration, which will appear to the hardware as a
large rx buffer update.  Bad things ensue.

The fix is to update the software shadow mailbox member when the special
case path is taken.
