[PATCH] softmac: don't reassociate if user asked for deauthentication
When wpa_supplicant exits, it uses SIOCSIWMLME to request
deauthentication. softmac then tries to reassociate without any user
intervention, which isn't the desired behaviour of this signal.
This change makes softmac only attempt reassociation if the remote
network itself deauthenticated us.

[TCP]: Fix sock_orphan dead lock
Calling sock_orphan inside bh_lock_sock in tcp_close can lead to dead
locks. For example, the inet_diag code holds sk_callback_lock without
disabling BH. If an inbound packet arrives during that admittedly tiny
window, it will cause a dead lock on bh_lock_sock. Another possible
path would be through sock_wfree if the network device driver frees the
tx skb in process context with BH enabled.
We can fix this by moving sock_orphan out of bh_lock_sock.
The tricky bit is to work out when we need to destroy the socket
ourselves and when it has already been destroyed by someone else.
By moving sock_orphan before the release_sock we can solve this
problem. This is because as long as we own the socket lock its
state cannot change.
So we simply record the socket state before the release_sock
and then check the state again after we regain the socket lock.
If the socket state has transitioned to TCP_CLOSE in the time being,
we know that the socket has been destroyed. Otherwise the socket is
still ours to keep.
Note that I've also moved the increment on the orphan count forward.
This may look like a problem as we're increasing it even if the socket
is just about to be destroyed where it'll be decreased again. However,
this simply enlarges a window that already exists. This also changes
the orphan count test by one.
Considering what the orphan count is meant to do this is no big deal.
This problem was discoverd by Ingo Molnar using his lock validator.

get alignment exceptions in the network stack at interrupt level.
The alignment exception handler does a __get_user to read the

[PATCH] powerpc/kprobes: fix singlestep out-of-line
We currently single-step inline if the instruction on which a kprobe is
inserted is a trap variant.
- variants (such as tdnei, used by BUG()) typically evaluate a condition
and cause a trap only if the condition is satisfied.
- kprobes uses the unconditional "trap" (0x7fe00008) and single-stepping
again on this instruction, resulting in another trap without
evaluating the condition is obviously incorrect.

[PATCH] via-rhine: zero pad short packets on Rhine I ethernet cards
Fixes Rhine I cards disclosing fragments of previously transmitted frames
in new transmissions.
Before transmission, any socket buffer (skb) shorter than the ethernet
minimum length of 60 bytes was zero-padded. On Rhine I cards the data can
later be copied into an aligned transmission buffer without copying this
padding. This resulted in the transmission of the frame with the extra
bytes beyond the provided content leaking the previous contents of this
buffer on to the network.
Now zero-padding is repeated in the local aligned buffer if one is used.
Following a suggestion from the via-rhine maintainer, no attempt is made
here to avoid the duplicated effort of padding the skb if it is known that
an aligned buffer will definitely be used. This is to make the change
"obviously correct" and allow it to be applied to a stable kernel if
necessary. There is no change to the flow of control and the changes are
only to the Rhine I code path.
The patch has run on an in-service Rhine-I host without incident. Frames
shorter than 60 bytes are now correctly zero-padded when captured on a
separate host. I see no unusual stats reported by ifconfig, and no unusual
log messages.

[NETFILTER] x_tables: fix compat related crash on non-x86
When iptables userspace adds an ipt_standard_target, it calculates the size
of the entire entry as:
sizeof(struct ipt_entry) + XT_ALIGN(sizeof(struct ipt_standard_target))
ipt_standard_target looks like this:
struct xt_standard_target
{
struct xt_entry_target target;
int verdict;
};
xt_entry_target contains a pointer, so when compiled for 64 bit the
structure gets an extra 4 byte of padding at the end. On 32 bit
architectures where iptables aligns to 8 byte it will also have 4
byte padding at the end because it is only 36 bytes large.
The compat_ipt_standard_fn in the kernel adjusts the offsets by
sizeof(struct ipt_standard_target) - sizeof(struct compat_ipt_standard_target),
which will always result in 4, even if the structure from userspace
was already padded to a multiple of 8. On x86 this works out by
accident because userspace only aligns to 4, on all other
architectures this is broken and causes incorrect adjustments to
the size and following offsets.

Currently we check PageDirty() in order to make the decision to swap out

ptes pointing to the page. We need to first unmap the ptes before checking
for PageDirty(). If unmap is successful then the page count of the page
will also be decreased so that pageout() works properly.
This is a fix necessary for 2.6.17. Without this fix we may migrate dirty
pages for filesystems without migration functions. Filesystems may keep
pointers to dirty pages. Migration of dirty pages can result in the
filesystem keeping pointers to freed pages.
Unmapping is currently not be separated out from removing all the
references to a page and moving the mapping. Therefore try_to_unmap will
be called again in migrate_page() if the writeout is successful. However,
it wont do anything since the ptes are already removed.

[PATCH] uml: fix patch mismerge
I sent a patch, it was applied as
cda402b283c34a24b091f78eee116963e9494762,
then it was applied again as
181ae4005d0a4010802be534d929b38c42b9ac06 by
mistake. But while the 1st time it modified (correctly) cow_header_v3, the
2nd it modified cow_header_v3_broken.

[PATCH] uml: error handling fixes
Blairsorblade noticed some confusion between our use of a system
call's return value and errno. This patch fixes a number of related
bugs -
using errno instead of a return value
using a return value instead of errno
forgetting to negate a error return to get a positive error code

[PATCH] uml: update defconfig
Bring defconfig up to date.
Also disable CONFIG_BLK_DEV_UBD_SYNC by default. By performing synchronous
I/O to the host, it slows things down, only protects against host crashes, and
can make a UML appear to hang while it waits for the host's disk.

[PATCH] md: Fix 'rdev->nr_pending' count when retrying barrier requests
When retrying a failed BIO_RW_BARRIER request, we need to keep the reference
in ->nr_pending over the whole retry. Currently, we only hold the reference
if the failed request is the *last* one to finish - which is silly, because it
would normally be the first to finish.
So move the rdev_dec_pending call up into the didn't-fail branch. As the rdev
isn't used in the later code, calling rdev_dec_pending earlier doesn't hurt.
