The kernel automatically evaluates partition tables of storage devices.
The code for evaluating OSF partitions contains a bug that leaks data
from kernel heap memory to userspace for certain corrupted OSF
partitions.
In more detail:
for (i = 0 ; i < le16_to_cpu(label->d_npartitions); i++, partition++) {
iterates from 0 to d_npartitions - 1, where d_npartitions is read from
the partition table without validation and partition is a pointer to an
array of at most 8 d_partitions.
Add the proper and obvious validation.

[ Changed the patch trivially to not repeat the whole le16_to_cpu()
thing, and to use an explicit constant for the magic value '8' ]

THP's collapse_huge_page() has an understandable but ugly difference
in when its huge page is allocated: inside if NUMA but outside if not.
It's hardly surprising that the memcg failure path forgot that, freeing
the page in the non-NUMA case, then hitting a VM_BUG_ON in get_page()
(or even worse, using the freed page).

Fix for a dumb preadv()/pwritev() compat bug - unlike the native
variants, the compat_... ones forget to check FMODE_P{READ,WRITE}, so
e.g. on pipe the native preadv() will fail with -ESPIPE and compat one
will act as readv() and succeed.
Not critical, but it's a clear bug with trivial fix, so IMO it's OK for
-final.

Josef had changed shrink_delalloc to exit after three shrink
attempts, which wasn't quite enough because new writers could
race in and steal free space.
But it also fixed deadlocks and stalls as we tried to recover
delalloc reservations. The code was tweaked to loop 1024
times, and would reset the counter any time a small amount
of progress was made. This was too drastic, and with a
lot of writers we can end up stuck in shrink_delalloc forever.
The shrink_delalloc loop is fairly complex because the caller is looping
too, and the caller will go ahead and force a transaction commit to make
sure we reclaim space.
This reworks things to exit shrink_delalloc when we've forced some
writeback and the delalloc reservations have gone down. This means
the writeback has not just started but has also finished at
least some of the metadata changes required to reclaim delalloc
space.
If we've got this wrong, we're returning ENOSPC too early, which
is a big improvement over the current behavior of hanging the machine.
Test 224 in xfstests hammers on this nicely, and with 1000 writers
trying to fill a 1GB drive we get our first ENOSPC at 93% full. The
other writers are able to continue until we get 100%.
This is a worst case test for btrfs because the 1000 writers are doing
small IO, and the small FS size means we don't have a lot of room
for metadata chunks.

btrfs_link() will insert 3 items(inode ref, dir name item and dir index item)
into the b+ tree and update 2 items(its inode, and parent's inode) in the b+
tree. So we should reserve space for these 5 items, not 3 items.

The btrfs DIO code leaks dip structs when dip->csums allocation
fails; bio->bi_end_io isn't set at the point where the free_ordered
branch is consequently taken, thus bio_endio doesn't call the function
which would free it in the normal case. Fix.

The btrfs fiemap code was incorrectly returning duplicate or overlapping
extents in some cases. cp was blindly trusting this result and we would
end up with a destination file that was bigger than the original because
some bytes were copied twice.
The fix here adjusts our offsets to make sure we're always moving
forward in the fiemap results.

When copy_from_user is only able to copy some of the bytes we requested,
we may end up creating a partially up to date page. To avoid garbage in
the page, we need to treat a partial copy as a zero length copy.
This makes the rest of the file_write code drop the page and
retry the whole copy instead of marking the partially up to
date page as dirty.

Commit 914ee295af418e936ec20a08c1663eaabe4cd07a fixed deadlocks in
btrfs_file_write where we would catch page faults on pages we had
locked.
But, there were a few problems:
1) The x86-32 iov_iter_copy_from_user_atomic code always fails to copy
data when the amount to copy is more than 4K and the offset to start
copying from is not page aligned. The result was btrfs_file_write
looping forever retrying the iov_iter_copy_from_user_atomic
We deal with this by changing btrfs_file_write to drop down to single
page copies when iov_iter_copy_from_user_atomic starts returning failure.
2) The btrfs_file_write code was leaking delalloc reservations when
iov_iter_copy_from_user_atomic returned zero. The looping above would
result in the entire filesystem running out of delalloc reservations and
constantly trying to flush things to disk.
3) btrfs_file_write will lock down page cache pages, make sure
any writeback is finished, do the copy_from_user and then release them.
Before the loop runs we check the first and last pages in the write to
see if they are only being partially modified. If the start or end of
the write isn't aligned, we make sure the corresponding pages are
up to date so that we don't introduce garbage into the file.
With the copy_from_user changes, we're allowing the VM to reclaim the
pages after a partial update from copy_from_user, but we're not
making sure the page cache page is up to date when we loop around to
resume the write.
We deal with this by pushing the up to date checks down into the page
prep code. This fits better with how the rest of file_write works.

shutdown
This patch addresses two outstanding bugs related to
T_TASK(cmd)->t_transport_aborted handling during TMR LUN_RESET and
active I/O shutdown.
This first involves adding two explict t_transport_aborted=1
assignments in core_tmr_lun_reset() in order to signal the task has
been aborted, and updating transport_generic_wait_for_tasks() to skip
sleeping when t_transport_aborted=1 has been set. This fixes an issue
where transport_generic_wait_for_tasks() would end up sleeping
indefinately when called from fabric module context while TMR
LUN_RESET was happening with long outstanding backend struct se_task
not yet being completed.
The second adds a missing call to
transport_remove_task_from_execute_queue() when
task->task_execute_queue=1 is set in order to fix an OOPs when
task->t_execute_list has not been dropped. It also fixes the same
case in transport_processing_shutdown() to prevent the issue from
happening during active I/O struct se_device shutdown.

This one liner patch fixes double free that will occur if add_mtd_blktrans_dev
fails. On failure it frees the input argument, but all its users also free it
on error which is natural thing to do. Thus don't free it.

For some unknown reasons resources needed by amd76xrom driver can be
unavailable. And instead of returning an error, the driver keeps going
and crash the kernel. This patch fixes the problem by making the driver
return -EBUSY if the resources are not available.

As inval_cache_and_wait_for_operation() drop and reclaim the lock
to invalidate the cache, some other thread may suspend the operation
before reaching the for(;;) loop. Therefore the loop must start with
checking the chip->state before reading status from the chip.

In the commit 08968041bef437ec363623cd3218c2b083537ada
(mtd: cfi_cmdset_0002: make sector erase command variable)
introdused a field sector_erase_cmd. In the same commit initialisation
of cfi->sector_erase_cmd made in cfi_chip_setup()
(file drivers/mtd/chips/cfi_probe.c), so the CFI chip has no problem:
...
cfi->cfi_mode = CFI_MODE_CFI;
cfi->sector_erase_cmd = CMD(0x30);
...
But for the JEDEC chips this initialisation is not carried out,
so the JEDEC chips have sector_erase_cmd == 0.
This patch adds the missing initialisation.

AGP and PCIE when running gnome-shell or kwin with compositing.
It appears the hw really doesn't like setting these registers while
stuff is running, this moves the setting of the registers into the modeset
since they aren't required to be changed anywhere else.

BZ29402
https://bugzilla.kernel.org/show_bug.cgi?id=29402
We can hit serious mis-synchronization in bio completion path of
blkdev_issue_zeroout() leading to a panic.
The problem is that when we are going to wait_for_completion() in
blkdev_issue_zeroout() we check if the bb.done equals issued (number of
submitted bios). If it does, we can skip the wait_for_completition()
and just out of the function since there is nothing to wait for.
However, there is a ordering problem because bio_batch_end_io() is
calling atomic_inc(&bb->done) before complete(), hence it might seem to
blkdev_issue_zeroout() that all bios has been completed and exit. At
this point when bio_batch_end_io() is going to call complete(bb->wait),
bb and wait does not longer exist since it was allocated on stack in
blkdev_issue_zeroout() ==> panic!
(thread 1) (thread 2)
bio_batch_end_io() blkdev_issue_zeroout()
if(bb) { ...
if (bb->end_io) ...
bb->end_io(bio, err); ...
atomic_inc(&bb->done); ...
... while (issued != atomic_read(&bb.done))
... (let issued == bb.done)
... (do the rest of the function)
... return ret;
complete(bb->wait);
^^^^^^^^
panic
We can fix this easily by simplifying bio_batch and completion counting.
Also remove bio_end_io_t *end_io since it is not used.

Now we've got multi-component we need to make sure that the DAPM context
(and hence register I/O context) we use to apply the pending updates at
the end of a DAPM sequence is the one we were processing rather than the
one that was used to initate the state change.

The i2c client device name (".2-001a" in this case, including
the separator period) for the AIC23 codec on the TI AM3517-EVM
was appended to the codec_name member of am3517evm_dai to
resolve the names mismatch happening in soc_bind_dai_link(),
due to which the card was not getting registered.

When vmscan.c calls page_referenced(), if an anon page was created
before a process forked, rmap will search for it in both of the
processes, even though one of them might have since broken COW.
If the child process mlocks the vma where the COWed page belongs to,
page_referenced() running on the page mapped by the parent would lead to
*vm_flags getting VM_LOCKED set erroneously (leading to the references
on the parent page being ignored and evicting the parent page too
early).
*mapcount would also be decremented by page_referenced_one even if the
page wasn't found by page_check_address.
This also lets pmdp_clear_flush_young_notify() go ahead on a
pmd_trans_splitting() pmd.
We hold the page_table_lock so __split_huge_page_map() must wait the
pmdp_clear_flush_young_notify() to complete before it can modify the
pmd. The pmd is also still mapped in userland so the young bit may
materialize through a tlb miss before split_huge_page_map runs.
This will provide a more accurate page_referenced() behavior during
split_huge_page().

In commit 567aba0b7997dad5fe3fb4aeb174ee9018df8c5b, the probe address
for tda8290_probe and tda8295_probe was hard-coded to 0x4b, which is the
default i2c address for those devices, but its possible for the device
to be at an alternate address, 0x42, which is the case for the HVR-1950.
If we probe the wrong address, probe fails and we have a non-working
device. We have the actual address passed into the function by way of
i2c_props, we just need to use it. Also fix up some copy/paste comment
issues and streamline debug spew a touch. Verified to restore my
HVR-1950 to full working order.
Special thanks to Ken Bass for reporting the issue in the first place,
and to both he and Gary Buhrmaster for aiding in debugging and analysis
of the problem.

After upgrading the kernel from stock Ubuntu 7.10 to
10.04, with no hardware changes, I started getting the dreaded DMA
TIMEOUT errors, followed by inability to encode until the machine was
rebooted.
I came across a post from Andy in March
(http://www.gossamer-threads.com/lists/ivtv/users/40943#40943) where he
speculates that perhaps the corrective actions being taken after a DMA
ERROR are not sufficient to recover the situation. After some testing
I suspect that this is indeed the case, and that in fact the corrective
action may be what hangs the card's DMA engine, rather than the
original error.
Specifically these DMA ERROR IRQs seem to present with two different
values in the IVTV_REG_DMASTATUS register: 0x11 and 0x13. The current
corrective action is to clear that status register back to 0x01 or
0x03, and then issue the next DMA request. In the case of a 0x13 this
seems to result in a minor glitch in the encoded stream due to the
failed transfer that was not retried, but otherwise things continue OK.
In the case of a 0x11 the card's DMA write engine is never heard from
again, and a DMA TIMEOUT follows shortly after. 0x11 is the killer.
I suspect that the two cases need to be handled differently. The
difference is in bit 1 (0x02), which is set when the error is about to
be successfully recovered, and clear when things are about to go bad.
Bit 1 of DMASTATUS is described differently in different places either
as a positive "write finished", or an inverted "write busy". If we
take the first definition, then when an error arises with state 0x11,
it means that the write did not complete. It makes sense to start a
new transfer, as in the current code. But if we take the second
definition, then 0x11 means "an error but the write engine is still
busy". Trying to feed it a new transfer in this situation might not be
a good idea.
As an experiment, I added code to ignore the DMA ERROR IRQ if DMASTATUS
is 0x11. I.e., don't start a new transfer, don't clear our flags, etc.
The hope was that the card would complete the transfer and issue a ENC
DMA COMPLETE, either successfully or with an error condition there.
However the card still hung.
The only remaining corrective action being taken with a 0x11 status was
then the write back to the status register to clear the error, i.e.
DMASTATUS = DMASTATUS & ~3. This would have the effect of clearing the
error bit 4, while leaving the lower bits indicating DMA write busy.
Strangely enough, removing this write to the status register solved the
problem! If the DMA ERROR IRQ with DMASTATUS=0x11 is completely
ignored, with no corrective action at all, then the card will complete
the transfer and issue a new IRQ. If the status register is written to
when it has the value 0x11, then the DMA engine hangs. Perhaps it's
illegal to write to
DMASTATUS while the read or write busy bit is set? At any rate, it
appears that the current corrective action is indeed making things
worse rather than better.
I put together a patch that modifies ivtv_irq_dma_err to do the
following:
- Don't write back to IVTV_REG_DMASTATUS.
- If write-busy is asserted, leave the card alone. Just extend the
timeout slightly.
- If write-busy is de-asserted, retry the current transfer.
This has completely fixed my DMA TIMEOUT woes. DMA ERR events still
occur, but now they seem to be correctly handled. 0x11 events no
longer hang the card, and 0x13 events no longer result in a glitch in
the stream, as the failed transfer is retried. I'm happy.
I've inlined the patch below in case it is of interest. As described
above, I have a theory about why it works (based on a different
interpretation of bit 1 of DMASTATUS), but I can't guarantee that my
theory is correct. There may be another explanation, or it may be a
fluke. Maybe ignoring that IRQ entirely would be equally effective?
Maybe the status register read/writeback sequence is race condition if
the card changes it in the mean time? Also as I am using a PVR-150
only, I have not been able to test it on other cards, which may be
especially relevant for 350s that support concurrent decoding.
Hopefully the patch does not break the DMA READ path.
Mike
[awalls@md.metrocast.net: Modified patch to add a verbose comment, make minor
brace reformats, and clear the error flags in the IVTV_REG_DMASTATUS iff both
read and write DMA were not in progress. Mike's conjecture about a race
condition with the writeback is correct; it can confuse the DMA engine.]
