[NET]: Fix memory leak in sys_{send,recv}msg() w/compat

From: Dave Johnson <djohnson+linux-kernel@sw.starentnetworks.com>

sendmsg()/recvmsg() syscalls from o32/n32 apps to a 64bit kernel will
cause a kernel memory leak if iov_len > UIO_FASTIOV for each syscall!

This is because both sys_sendmsg() and verify_compat_iovec() kmalloc a
new iovec structure.  Only the one from sys_sendmsg() is free'ed.

I wrote a simple test program to confirm this after identifying the
problem:

http://davej.org/programs/testsendmsg.c

Note that the below fix will break solaris_sendmsg()/solaris_recvmsg() as
it also calls verify_compat_iovec() but expects it to malloc internally.

15 years ago[PATCH] cpuset release ABBA deadlock fix
Paul Jackson [Tue, 9 Aug 2005 17:07:59 +0000]
[PATCH] cpuset release ABBA deadlock fix

Fix possible cpuset_sem ABBA deadlock if 'notify_on_release' set.

For a particular usage pattern, creating and destroying cpusets fairly
frequently using notify_on_release, on a very large system, this deadlock
can be seen every few days.  If you are not using the cpuset
notify_on_release feature, you will never see this deadlock.

The existing code, on task exit (or cpuset deletion) did:

  get cpuset_sem
  if cpuset marked notify_on_release and is ready to release:
    compute cpuset path relative to /dev/cpuset mount point
    call_usermodehelper() forks /sbin/cpuset_release_agent with path
  drop cpuset_sem

Unfortunately, the fork in call_usermodehelper can allocate memory, and
allocating memory can require cpuset_sem, if the mems_generation values
changed in the interim.  This results in an ABBA deadlock, trying to obtain
cpuset_sem when it is already held by the current task.

To fix this, I put the cpuset path (which must be computed while holding
cpuset_sem) in a temporary buffer, to be used in the call_usermodehelper
call of /sbin/cpuset_release_agent only _after_ dropping cpuset_sem.

So the new logic is:

  get cpuset_sem
  if cpuset marked notify_on_release and is ready to release:
    compute cpuset path relative to /dev/cpuset mount point
    stash path in kmalloc'd buffer
  drop cpuset_sem
  call_usermodehelper() forks /sbin/cpuset_release_agent with path
  free path

The sharp eyed reader might notice that this patch does not contain any
calls to kmalloc.  The existing code in the check_for_release() routine was
already kmalloc'ing a buffer to hold the cpuset path.  In the old code, it
just held the buffer for a few lines, over the cpuset_release_agent() call
that in turn invoked call_usermodehelper().  In the new code, with the
application of this patch, it returns that buffer via the new char
**ppathbuf parameter, for later use and freeing in cpuset_release_agent(),
which is called after cpuset_sem is dropped.  Whereas the old code has just
one call to cpuset_release_agent(), right in the check_for_release()
routine, the new code has three calls to cpuset_release_agent(), from the
various places that a cpuset can be released.

This patch has been build and booted on SN2, and passed a stress test that
previously hit the deadlock within a few seconds.

[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().

[PATCH] VIA VT8235 PCI quirk

Like many other southbridges from different manufacturers, VIA VT8235
chip has two non-standard BARs for power management and SMBus registers
(see the datasheet at http://www.via.com.tw).

This new quirk routine fixes boot problem with 2.6.13-rc2/rc6 kernels on
Targa Visionary 811 Athlon64 laptop, as reported by Mikael Pettersson
<mikpe@csd.uu.se>.

[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 [Sun, 7 Aug 2005 16:42:25 +0000]
[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).

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

Tejun Heo [Fri, 5 Aug 2005 20:28:11 +0000]
[PATCH] blk: fix tag shrinking (revive real_max_size)

My patch in commit fa72b903f75e4f0f0b2c2feed093005167da4023 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.

Petr Vandrovec [Fri, 5 Aug 2005 13:50:07 +0000]
[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
47f176fdaf8924bc83fddcf9658f2fd3ef60d573, "[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 [Fri, 5 Aug 2005 02:52:03 +0000]
[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.

David S. Miller [Fri, 5 Aug 2005 02:52:01 +0000]
[PATCH] tcp: fix TSO sizing bugs

MSS changes can be lost since we preemptively initialize the tso_segs count

So, by the time we send it out, the tso_size information can be stale due
to PMTU events.  This mucks up all of the logic in our send engine, and can

Another problem we have is that we're storing the tp->mss_cache, not the

per millisec) and low/full speed (1-64 bytes per millisec) microframe

John W. Linville [Fri, 5 Aug 2005 01:06:10 +0000]
[PATCH] PCI: restore BAR values after D3hot->D0 for devices that need it

Some PCI devices (e.g. 3c905B, 3c556B) lose all configuration
(including BARs) when transitioning from D3hot->D0.  This leaves such
a device in an inaccessible state.  The patch below causes the BARs
to be restored when enabling such a device, so that its driver will
be able to access it.

The patch also adds pci_restore_bars as a new global symbol, and adds a
correpsonding EXPORT_SYMBOL_GPL for that.

Some firmware (e.g. Thinkpad T21) leaves devices in D3hot after a
(re)boot.  Most drivers call pci_enable_device very early, so devices
left in D3hot that lose configuration during the D3hot->D0 transition
will be inaccessible to their drivers.

Drivers could be modified to account for this, but it would
be difficult to know which drivers need modification.  This is
especially true since often many devices are covered by the same
driver.  It likely would be necessary to replicate code across dozens
of drivers.

The patch below should trigger only when transitioning from D3hot->D0
(or at boot), and only for devices that have the "no soft reset" bit
cleared in the PM control register.  I believe it is safe to include
this patch as part of the PCI infrastructure.

The cleanest implementation of pci_restore_bars was to call
pci_update_resource.  Unfortunately, that does not currently exist
for the sparc64 architecture.  The patch below includes a null
implemenation of pci_update_resource for sparc64.

Some have expressed interest in making general use of the the
pci_restore_bars function, so that has been exported to GPL licensed
modules.
