Harald Welte 8b83bc77bf [PATCH] don't try to do any NAT on untracked connections
With the introduction of 'rustynat' in 2.6.11, the old tricks of preventing
NAT of 'untracked' connections (e.g. NOTRACK target in 'raw' table) are no
longer sufficient.

The ip_conntrack_untracked.status |= IPS_NAT_DONE_MASK effectively
prevents iteration of the 'nat' table, but doesn't prevent nat_packet()
to be executed.  Since nr_manips is gone in 'rustynat', nat_packet() now
implicitly thinks that it has to do NAT on the packet.

This patch fixes that problem by explicitly checking for
ip_conntrack_untracked in ip_nat_fn().

(see the datasheet at http://www.via.com.tw).

This new quirk routine fixes boot problem with 2.6.13-rc2/rc6 kernels on

Antonino Daplas db6778db7e [PATCH] nvidiafb: Fix initial display corruption on certain laptops
Reported by:Vincent Fortier (Bugzilla Bug 4768)

"At boot time the screen appears moved to the mid right portion of the actual
video pannel making the end of the line appears at the left edge...  It simply
looks like moved half way to the right"

His particular hardware has a display with an unusual dimension (1920x1200) but
unfortunately has no EDID block. None of the entries in the global mode
database is correct for this particular display, and it particularly has
difficulty scaling up 640x480 (the default startup mode of nvidiafb) to
1920x1200 which causes the above described problem.

1, Add 1920x1200 to the global mode database.

2. Let nvidiafb base the startup mode from the flatpanel dimensions only if the
  EDID block is absent, no boot mode parameter is specified by the user, and
  a flatpanel/LCD display is attached.

Miklos Szeredi 68b47139ea [PATCH] namespace.c: fix bind mount from foreign namespace
I'm resending this patch, because I still believe it's the correct fix.

Tested before/after applying the patch with a test application
available from:

  http://www.inf.bme.hu/~mszeredi/nstest.c

Bind mount from a foreign namespace results in an un-removable mount.
The reason is that mnt->mnt_namespace is copied from the old mount in
clone_mnt().  Because of this check_mnt() in sys_umount() will fail.

The solution is to set mnt->mnt_namespace to current->namespace in
clone_mnt().  clone_mnt() is either called from do_loopback() or
copy_tree().  copy_tree() is called from do_loopback() or
copy_namespace().

When called (directly or indirectly) from do_loopback(), always
current->namspace is being modified: check_mnt(nd->mnt).  So setting
mnt->mnt_namespace to current->namspace is the right thing to do.

When called from copy_namespace(), the setting of mnt_namespace is
irrelevant, since mnt_namespace is reset later in that function for
all copied mounts.

Jamie said:

  This patch is correct.  The old code was buggy for more fundamental and
  serious reason: it broke the invariant that a tree of vfsmnts all have the
  same value of mnt_namespace (and the same for the mnt_list list).

Ivan Kokshaysky cf7bee5a0b [PATCH] Fix restore of 64-bit PCI BAR's
For 64-bit BAR[i] only pci_dev->resource[i] is valid, ->resource[i+1]
slot is unused and contains zeroes in all fields.

So when we update a PCI BAR, all we need is just to check that we're
going to update a _valid_ resource.

Also make sure to write high bits - use "x >> 16 >> 16" (rather than the
simpler ">> 32") to avoid warnings on 32-bit architectures where we're
not going to have any high bits.

Tejun Heo ba02508248 [PATCH] blk: fix tag shrinking (revive real_max_size)
My patch in commit fa72b903f7 incorrectly
removed blk_queue_tag->real_max_depth.

The original resize implementation was incorrect in the following
points.

 * actual allocation size of tag_index was shorter than real_max_size,
   but assumed to be of the same size, possibly causing memory access
   beyond the allocated area.
 * bits in tag_map between max_deptn and real_max_depth were
   initialized to 1's, making the tags permanently reserved.

In an attempt to fix above two bugs, I had removed allocation optimization
in init_tag_map and real_max_size.  Tag map/index were allocated and freed
immediately during resize.

Unfortunately, I wasn't considering that tag map/index can be resized
dynamically with tags beyond new_depth active.  This led to accessing
freed area after shrinking tags and led to the following bug reporting
thread on linux-scsi.

   http://marc.theaimsgroup.com/?l=linux-scsi&m=112319898111885&w=2

To fix the problem, I've revived real_max_depth without allocation
optimization in init_tag_map, and Andrew Vasquez confirmed that the
problem was fixed.  As Jens is not going to be available for a week, he
asked me to make sure that this patch reaches you.

   http://marc.theaimsgroup.com/?l=linux-scsi&m=112325778530886&w=2

Also, a comment was added to make sure that real_max_size is needed for
dynamic shrinking.

Depending on the hugepage configuration, this crash can be triggered by an

configuration is now done via PNPACPI, which reads out the correct values
out of the DSDT-table.  Note that you have to have CONFIG_PNP,

Andrew Morton 30e835e366 [PATCH] REPORTING-BUGS: track regressions
Add a new record to the REPORTING-BUGS template: "Most recent kernel version
which did not have the bug:".  So we can spot regressions more easily.

Petr Vandrovec 403fe5ae57 [PATCH] rtc: msleep() cannot be used from interrupt
Since the beginning of July my Opteron box was randomly crashing and
being rebooted by hardware watchdog.  Today it finally did it in front
of me, and this patch will hopefully fix it.

The problem is that at the end of June (the 28th, to be exact: commit
47f176fdaf, "[PATCH] Using msleep()
instead of HZ") rtc_get_rtc_time was converted to use msleep() instead
of busy waiting.  But rtc_get_rtc_time is used by hpet_rtc_interrupt,
and scheduling is not allowed during interrupt.  So I'm reverting this
part of original change, replacing msleep() back with busy loop.

The original code was busy waiting for up to 20ms, but on my hardware in
the worst case update-in-progress bit was asserted for at most 363
passes through loop (on 2GHz dual Opteron), much less than even one
jiffie, not even talking about 20ms.  So I changed code to just wait
only as long as necessary.  Otherwise when RTC was set to generate
8192Hz timer, it stopped doing anything for 20ms (160 pulses were
skipped!) from time to time, and this is rather suboptimal as far as I
can tell.

Simon Derr 2f60f8d357 [PATCH] __vm_enough_memory() signedness fix
We have found what seems to be a small bug in __vm_enough_memory() when
sysctl_overcommit_memory is set to OVERCOMMIT_NEVER.

When this bug occurs the systems fails to boot, with /sbin/init whining
about fork() returning ENOMEM.

We hunted down the problem to this:

The deferred update mecanism used in vm_acct_memory(), on a SMP system,
allows the vm_committed_space counter to have a negative value.

This should not be a problem since this counter is known to be inaccurate.

But in __vm_enough_memory() this counter is compared to the `allowed'
variable, which is an unsigned long.  This comparison is broken since it
will consider the negative values of vm_committed_space to be huge positive
values, resulting in a memory allocation failure.
