[PATCH] sky2: allow dual port usage

If both ports are receiving on the SysKonnect dual port cards,
then it appears the bus interface unit can give an interrupt status
for frame before DMA has completed.  This leads to bogus frames
and general confusion. This is why receive checksumming is also
messed up on dual port cards.

A workaround for the out of order receive problem is to eliminating
split transactions on PCI-X.

This version is based of the current linux-2.6.git including earlier

of the rounded ones.  This prevents us from potentially walking of

13 years ago[SCTP]: A better solution to fix the race between sctp_peeloff() and
Vladislav Yasevich [Fri, 19 May 2006 18:01:18 +0000]
[SCTP]: A better solution to fix the race between sctp_peeloff() and
sctp_rcv().

The goal is to hold the ref on the association/endpoint throughout the
state-machine process.  We accomplish like this:

  /* ref on the assoc/ep is taken during lookup */

  if owned_by_user(sk)
  sctp_add_backlog(skb, sk);
  else
  inqueue_push(skb, sk);

  /* drop the ref on the assoc/ep */

However, in sctp_add_backlog() we take the ref on assoc/ep and hold it
while the skb is on the backlog queue.  This allows us to get rid of the
sock_hold/sock_put in the lookup routines.

Now sctp_backlog_rcv() needs to account for potential association move.
In the unlikely event that association moved, we need to retest if the
new socket is locked by user.  If we don't this, we may have two packets
racing up the stack toward the same socket and we can't deal with it.
If the new socket is still locked, we'll just add the skb to its backlog
continuing to hold the ref on the association.  This get's rid of the
need to move packets from one backlog to another and it also safe in
case new packets arrive on the same backlog queue.

The last step, is to lock the new socket when we are moving the
association to it.  This is needed in case any new packets arrive on
the association when it moved.  We want these to go to the backlog since
we would like to avoid the race between this new packet and a packet
that may be sitting on the backlog queue of the old socket toward the
same association.

[NETFILTER]: Fix do_add_counters race, possible oops or info leak (CVE-2006-0039)

Solar Designer found a race condition in do_add_counters(). The beginning

above, but it might not be the same in reality. In case the integer
overflow and/or the race condition are triggered, paddc->num_counters
might not match the allocation size for paddc. If the check below
(t->private->number != paddc->num_counters) nevertheless passes (perhaps
this requires the race condition to be triggered), IPT_ENTRY_ITERATE()
would read kernel memory beyond the allocation size, potentially causing
an oops or leaking sensitive data (e.g., passwords from host system or

[PATCH] sbp2: add ability to override hardwired blacklist

In case the blacklist with workarounds for device bugs yields a false
positive, the module load parameter can now also be used as an override
instead of an addition to the blacklist.

Stefan Richter [Mon, 15 May 2006 20:06:37 +0000]
[PATCH] sbp2: add read_capacity workaround for iPod

Apple decided to copy some USB stupidity over to FireWire.

The sector number returned by iPods from read_capacity is one too many.
This may cause I/O errors, especially if the kernel is configured for EFI
partition support. We use the same workaround as usb-storage but have to
check for different model IDs.

[PATCH] sbp2: consolidate workarounds

Grand unification of the three types of workarounds we have so far.

The "skip mode page 8" workaround is now limited to devices which
pretend to be of TYPE_DISK instead of TYPE_RBC. This workaround is no
longer enabled for Initio bridges.

Patch update in anticipation of more workarounds:
 - Add module parameter "workarounds".
 - Deprecate parameter "force_inquiry_hack".
 - Compose the blacklist of a compound type for better readability and
   extensibility.
 - Remove a now unused #define.

Dimitry Andric [Wed, 17 May 2006 15:31:11 +0000]
[ARM] 3529/1: s3c24xx: fix restoring control register with undefined instruction

Patch from Dimitry Andric

In arch/arm/mach-s3c2410/sleep.S, the coprocessor registers are saved at
suspend time, and restored at resume time. However, an undefined
instruction is used when attempting to restore a non-existent "auxiliary
control register".  This leads to a crash on S3C2412, which has an ARM926
core instead of an ARM920.

At suspend time, the following fragment runs:

mrc p15, 0, r7, c2, c0, 0 @ translation table base address
mrc p15, 0, r8, c2, c0, 0 @ auxiliary control register
mrc p15, 0, r9, c1, c0, 0 @ control register

and at resume time, the following fragment runs:

mcr p15, 0, r7, c2, c0, 0 @ translation table base
mcr p15, 0, r8, c1, c1, 0 @ auxilliary control
...
mcr p15, 0, r9, c1, c0, 0 @ turn on MMU, etc

There are several problems with these fragments:
1. The ARM920 and ARM926 cores don't have any "auxiliary control
   register", at least not according to the ARM920 and ARM926 TRM's.
2. The 2nd line of suspend erroneously saves the c2 register again.
3. This saved c2 value is restored using an undefined instruction.  For
   some reason this does not crash on ARM920, but does crash on ARM926.

The following patch fixes all these problems.

[TCP]: reno sacked_out count fix

From: "Angelo P. Castellani" <angelo.castellani+lkml@gmail.com>

Using NewReno, if a sk_buff is timed out and is accounted as lost_out,
it should also be removed from the sacked_out.

This is necessary because recovery using NewReno fast retransmit could
take up to a lot RTTs and the sk_buff RTO can expire without actually
being really lost.

left_out = sacked_out + lost_out
in_flight = packets_out - left_out + retrans_out

Using NewReno without this patch, on very large network losses,
left_out becames bigger than packets_out + retrans_out (!!).

For this reason unsigned integer in_flight overflows to 2^32 - something.

 - There are more than 1000 nanoseconds per millisecond; setting the clock
   down to 125 KHz now works properly.

that number was wrongly used to flag dynamic allocation of a bus number.

This patch resolves that issue; now negative numbers trigger dynamic alloc.

It also updates the how-to-write-a-controller-driver overview to mention
this stuff.

[PATCH] SPI: per-transfer overrides for wordsize and clocking

Some protocols (like one for some bitmap displays) require different clock
speed or word size settings for each transfer in an SPI message. This adds
those parameters to struct spi_transfer.  They are to be used when they are
nonzero; otherwise the defaults from spi_device are to be used.

The patch also adds a setup_transfer callback to spi_bitbang, uses it for
messages that use those overrides, and implements it so that the pure
bitbanging code can help resolve any questions about how it should work.

Roland Dreier [Mon, 15 May 2006 18:41:00 +0000]
[PATCH] slab: Fix kmem_cache_destroy() on NUMA

With CONFIG_NUMA set, kmem_cache_destroy() may fail and say "Can't
free all objects."  The problem is caused by sequences such as the
following (suppose we are on a NUMA machine with two nodes, 0 and 1):

 * Allocate an object from cache on node 0.
 * Free the object on node 1.  The object is put into node 1's alien
   array_cache for node 0.
 * Call kmem_cache_destroy(), which ultimately ends up in __cache_shrink().
 * __cache_shrink() does drain_cpu_caches(), which loops through all nodes.
   For each node it drains the shared array_cache and then handles the
   alien array_cache for the other node.

However this means that node 0's shared array_cache will be drained,
and then node 1 will move the contents of its alien[0] array_cache
into that same shared array_cache.  node 0's shared array_cache is
never looked at again, so the objects left there will appear to be in
use when __cache_shrink() calls __node_shrink() for node 0.  So
__node_shrink() will return 1 and kmem_cache_destroy() will fail.

This patch fixes this by having drain_cpu_caches() do
drain_alien_cache() on every node before it does drain_array() on the
nodes' shared array_caches.

The problem was originally reported by Or Gerlitz <ogerlitz@voltaire.com>.

This fixes some boot failures on Dell and Unisys systems with memory

[PATCH] Fix pSeries identification in prom_init.c

The OF trampoline code prom_init.c still needs to identify IBM pSeries
(PAPR) machines in order to run some platform specific code on them like
instanciating the TCE tables. The code doing that detection was changed
recently in 2.6.17 early stages but was done slightly incorrectly. It
should be testing for an exact match of "chrp" and it currently tests
for anything that begins with "chrp". That means it will incorrectly
match with platforms using Maple-like device-trees and have open
firmware. This fixes it by using strcmp instead of strncmp to match what
the actual platform detection code does.

It looks like a hardware bug because status arrives for a packet but no
