[NET]: Fix race condition in sk_wait_event().
It is broken, the condition is checked out of socket lock. It is
wonderful the bug survived for so long time.
[ This fixes bugzilla #6233:
race condition in tcp_sendmsg when connection became established ]

[PATCH] fix free swap cache latency
Lee Revell reported 28ms latency when process with lots of swapped memory
exits.
2.6.15 introduced a latency regression when unmapping: in accounting the
zap_work latency breaker, pte_none counted 1, pte_present PAGE_SIZE, but a
swap entry counted nothing at all. We think of pages present as the slow
case, but Lee's trace shows that free_swap_and_cache's radix tree lookup
can make a lot of work - and we could have been doing it many thousands of
times without a latency break.
Move the zap_work update up to account swap entries like pages present.
This does account non-linear pte_file entries, and unmap_mapping_range
skipping over swap entries, by the same amount even though they're quick:
but neither of those cases deserves complicating the code (and they're
treated no worse than they were in 2.6.14).

[PATCH] kbuild: fix buffer overflow in modpost
Jiri Benc <jbenc@suse.cz> reported that modpost would stop with SIGABRT if
used with long filepaths.
The error looked like:
> Building modules, stage 2.

> *** glibc detected *** scripts/mod/modpost: realloc(): invalid next size:
+0x0809f588 ***

Fix this by allocating at least the required memory + SZ bytes each time.

glibc detected bug above. Based on patch originally submitted by: Jiri

[PATCH] nfsservctl(): remove user-triggerable printk
A user can use nfsservctl() to spam the logs.
This can happen because the arguments to the nfsservctl() system call are
versioned. This is a good thing. However, when a bad version is detected,
the kernel prints a message and then returns an error.

[PATCH] dm stripe: Fix bounds
The dm-stripe target currently does not enforce that the size of a stripe
device be a multiple of the chunk-size. Under certain conditions, this can
lead to I/O requests going off the end of an underlying device. This
test-case shows one example.
echo "0 100 linear /dev/hdb1 0" | dmsetup create linear0
echo "0 100 linear /dev/hdb1 100" | dmsetup create linear1
echo "0 200 striped 2 32 /dev/mapper/linear0 0 /dev/mapper/linear1 0" | \
dmsetup create stripe0
dd if=/dev/zero of=/dev/mapper/stripe0 bs=1k
This will produce the output:
dd: writing '/dev/mapper/stripe0': Input/output error
97+0 records in
96+0 records out
And in the kernel log will be:
attempt to access beyond end of device
dm-0: rw=0, want=104, limit=100
The patch will check that the table size is a multiple of the stripe
chunk-size when the table is created, which will prevent the above striped
device from being created.
This should not affect tools like LVM or EVMS, since in all the cases I can
think of, striped devices are always created with the sizes being a
multiple of the chunk-size.
The size of a stripe device must be a multiple of its chunk-size.
(akpm: that typecast is quite gratuitous)

[PATCH] x86: check for online cpus before bringing them up
Bryce reported a bug wherein offlining CPU0 (on x86 box) and then
subsequently onlining it resulted in a lockup.
On x86, CPU0 is never offlined. The subsequent attempt to online CPU0
doesn't take that into account. It actually tries to bootup the already
booted CPU. Following patch fixes the problem (as acknowledged by Bryce).
Please consider for inclusion in 2.6.16.
Check if cpu is already online.

[PATCH] powerpc: Clarify wording for CRASH_DUMP Kconfig option
The wording of the CRASH_DUMP Kconfig option is not very clear. It gives you a
kernel that can be used _as_ the kdump kernel, not a kernel that can boot into
a kdump kernel.

powerpc: Fix problem with time going backwards
The recent changes to keep gettimeofday in sync with xtime had the side
effect that it was occasionally possible for the time reported by
gettimeofday to go back by a microsecond. There were two reasons:
(1) when we recalculated the offsets used by gettimeofday every 2^31
timebase ticks, we lost an accumulated fractional microsecond, and
(2) because the update is done some time after the notional start of
jiffy, if ntp is slowing the clock, it is possible to see time go backwards
when the timebase factor gets reduced.
This fixes it by (a) slowing the gettimeofday clock by about 1us in
2^31 timebase ticks (a factor of less than 1 in 3.7 million), and (b)
adjusting the timebase offsets in the rare case that the gettimeofday
result could possibly go backwards (i.e. when ntp is slowing the clock
and the timer interrupt is late). In this case the adjustment will
reduce to zero eventually because of (a).

[PATCH] Fix ext2 readdir f_pos re-validation logic
This fixes not one, but _two_, silly (but admittedly hard to hit) bugs
in the ext2 filesystem "readdir()" function. It also cleans up the code
to avoid the unnecessary goto mess.
The bugs were related to re-valiating the f_pos value after somebody had
either done an "lseek()" on the directory to an invalid offset, or when
the offset had become invalid due to a file being unlinked in the
directory. The code would not only set the f_version too eagerly, it
would also not update f_pos appropriately for when the offset fixup took
place.
When that happened, we'd occasionally subsequently fail the readdir()
even when we shouldn't (no real harm done, but an ugly printk, and
obviously you would end up not necessarily seeing all entries).
Thanks to Masoud Sharbiani <masouds@google.com> who noticed the problem
and had a test-case for it, and also fixed up a thinko in the first
version of this patch.

It seems that setting scheduling policy and priorities is also the kind of

So use CAP_SYS_NICE for controlling migration permissions.

[PATCH] page migration: fail if page is in a vma flagged VM_LOCKED
page migration currently simply retries a couple of times if try_to_unmap()
fails without inspecting the return code.
However, SWAP_FAIL indicates that the page is in a vma that has the
VM_LOCKED flag set (if ignore_refs ==1). We can check for that return code
and avoid retrying the migration.
migrate_page_remove_references() now needs to return a reason why the
failure occured. So switch migrate_page_remove_references to use -Exx
style error messages.

Fix a direct I/O locking issue revealed by the new mutex code.
Affects only XFS (i.e. DIO_OWN_LOCKING case) - currently it is
not possible to get i_mutex locking correct when using DIO_OWN
direct I/O locking in a filesystem due to indeterminism in the
possible return code/lock/unlock combinations. This can cause
a direct read to attempt a double i_mutex unlock inside XFS.
We're now ensuring __blockdev_direct_IO always exits with the
inode i_mutex (still) held for a direct reader.
Tested with the three different locking modes (via direct block

[PATCH] EDAC: disable sysfs interface
- Disable the EDAC sysfs code. The sysfs interface that EDAC presents to
user space needs more thought, and is likely to change substantially.
Therefore disable it for now so users don't start depending on it in its
current form.
- Disable the default behavior of calling panic() when an uncorrectible
error is detected (since for now, there is no sysfs interface that allows
the user to configure this behavior).

[PATCH] NFS: Fix a potential panic in O_DIRECT
Based on an original patch by Mike O'Connor and Greg Banks of SGI.
Mike states:
A normal user can panic an NFS client and cause a local DoS with
'judicious'(?) use of O_DIRECT. Any O_DIRECT write to an NFS file where the
user buffer starts with a valid mapped page and contains an unmapped page,
will crash in this way. I haven't followed the code, but O_DIRECT reads with
similar user buffers will probably also crash albeit in different ways.
Details: when nfs_get_user_pages() calls get_user_pages(), it detects and
correctly handles get_user_pages() returning an error, which happens if the
first page covered by the user buffer's address range is unmapped. However,
if the first page is mapped but some subsequent page isn't, get_user_pages()
will return a positive number which is less than the number of pages requested
(this behaviour is sort of analagous to a short write() call and appears to be
intentional). nfs_get_user_pages() doesn't detect this and hands off the
array of pages (whose last few elements are random rubbish from the newly
allocated array memory) to it's caller, whence they go to
nfs_direct_write_seg(), which then totally ignores the nr_pages it's given,
and calculates its own idea of how many pages are in the array from the user
buffer length. Needless to say, when it comes to transmit those uninitialised
page* pointers, we see a crash in the network stack.

[PATCH] Fix sigaltstack corruption among cloned threads
This patch fixes alternate signal stack corruption among cloned threads
with CLONE_SIGHAND (and CLONE_VM) for linux-2.6.16-rc6.
The value of alternate signal stack is currently inherited after a call of
clone(... CLONE_SIGHAND | CLONE_VM). But if sigaltstack is set by a
parent thread, and then if multiple cloned child threads (+ parent threads)
call signal handler at the same time, some threads may be conflicted -
because they share to use the same alternative signal stack region.
Finally they get sigsegv. It's an undesirable race condition. Note that
child threads created from NPTL pthread_create() also hit this conflict
when the parent thread uses sigaltstack, without my patch.
To fix this problem, this patch clears the child threads' sigaltstack
information like exec(). This behavior follows the SUSv3 specification.
In SUSv3, pthread_create() says "The alternate stack shall not be inherited
(when new threads are initialized)". It means that sigaltstack should be
cleared when sigaltstack memory space is shared by cloned threads with
CLONE_SIGHAND.
Note that I chose "if (clone_flags & CLONE_SIGHAND)" line because:
- If clone_flags line is not existed, fork() does not inherit sigaltstack.
- CLONE_VM is another choice, but vfork() does not inherit sigaltstack.
- CLONE_SIGHAND implies CLONE_VM, and it looks suitable.
- CLONE_THREAD is another candidate, and includes CLONE_SIGHAND + CLONE_VM,
but this flag has a bit different semantics.
I decided to use CLONE_SIGHAND.
[ Changed to test for CLONE_VM && !CLONE_VFORK after discussion --Linus ]

[PATCH] x86-64: Fix up handling of non canonical user RIPs
EM64T CPUs have somewhat weird error reporting for non canonical RIPs in
SYSRET.
We can't handle any exceptions there because the exception handler would
end up running on the user stack which is unsafe.
To avoid problems any code that might end up with a user touched pt_regs
should return using int_ret_from_syscall. int_ret_from_syscall ends up
using IRET, which allows safe exceptions.

[ARM] iwmmxt thread state alignment
This patch removes the reliance of iwmmxt on hand coded alignments.
Since thread_info is always 8K aligned, specifying that fpstate is
8-byte aligned achieves the same effect without needing to resort
to hand coded alignments.

[ARM] 3356/1: Workaround for the ARM1136 I-cache invalidation problem
Patch from Catalin Marinas
ARM1136 erratum 371025 (category 2) specifies that, under rare
conditions, an invalidate I-cache by MVA (line or range) operation can
fail to invalidate a cache line. The recommended workaround is to
either invalidate the entire I-cache or invalidate the range by
set/way rather than MVA.
Note that for a 16K cache size, invalidating a 4K page by set/way is
equivalent to invalidating the entire I-cache.

[SCSI] zfcp: fix device registration issues
The patch fixes following issues:
(1) Replace scsi_add_device with scsi_scan_target.
(Thus the rport instead of the scsi_host becomes parent of a
scsi_target again.)
(2) Avoid scsi_device allocation during registration of an remote port.
(Would be done during fc_scsi_scan_rport.)
(3) Fix queuecommand behaviour when an zfcp unit is blocked.
(Call scsi_done with DID_NO_CONNECT instead of returning
SCSI_MLQUEUE_DEVICE_BUSY otherwise we might end up waiting
for completion in blk_execute_rq for ever.)
