commit 6ff10464096540e14d7575a72c50d0316d003714 upstream.
The usbfs driver manages a list of completed asynchronous URBs. But
it is too eager to free the entries on this list: destroy_async() gets
called whenever an interface is unbound or a device is removed, and it
deallocates the outstanding struct async entries for all URBs on that
interface or device. This is wrong; the user program should be able
to reap an URB any time after it has completed, regardless of whether
or not the interface is still bound or the device is still present.
This patch (as1222) moves the code for deallocating the completed list
entries from destroy_async() to usbdev_release(). The outstanding
entries won't be freed until the user program has closed the device
file, thereby eliminating any possibility that the remaining URBs
might still be reaped.
This fixes a bug in which a program can hang in the USBDEVFS_REAPURB
ioctl when the device is unplugged.

commit c497e715f93d148d751c055401568684eea0bf6b upstream.
Enable the SD-Card interface on the GI 0431 HSUPA stick from Option.
The unusual_devs.h entry is necessary because the device descriptor is
vendor-specific. That prevents usb-storage from binding to it as an
interface driver.

commit 8a0845c51b2e300f5204a323b874f7f58ea0eff7 upstream.
The "c-enter" USB to Toshiba 1.8" IDE enclosure needs special treatment
to work flawlessly. This patch is absolutely trivial, as the integrated
USB-IDE bridge is already identified to be an "unusual" device, only the
bcdDevice is different (lower) to the bcdDeviceMin already included in
the kernel.
It is a Prolific 2507 bridge.

the pieces are in place (ie, cac477e8f1038c41b6f29d3161ce351462ef3df7).
Removing the IDs from option allows cdc-acm to handle the device.

commit 508db8c954d55ed30f870d2c24d741ba6269d13c upstream.
ehci-hcd uses usb_get_urb() and usb_put_urb() in an unbalanced way causing
isochronous URB's kref.counts incrementing once per usb_submit_urb() call.
The culprit is *usb being set to NULL when usb_put_urb() is called after URB
is given back.
Due to other fixes there is no need for ehci-hcd to deal with usb_get_urb()
nor usb_put_urb() anymore, so patch removes their usages in ehci-hcd.
Patch also makes ehci_to_hcd(ehci)->self.bandwidth_allocated adjust, if a
stream finishes.

commit 391016f6e2fe3b9979b4c6880a76e5e434d6947c upstream.
This patch (as1225) fixes a bug in ehci-hcd. The condition for
whether unlinked QHs can become IDLE should not be that the controller
is halted, but rather that the controller isn't running. In other
words when the root hub is suspended, the hardware doesn't own any
QHs.
This fixes a problem that can show up during hibernation: If a QH is
only partially unlinked when the root hub is frozen, then when the
root hub is thawed the QH won't be in the IDLE state. As a result it
can't be used properly for new URB submissions.

commit cd8f894eacf13996d920fdd2aef1afc55156b191 upstream.
Analog support for HVR-1250 has not been completed, but does exist for
the HVR-1800.
Since both cards use the same driver, it tries to create the analog
dev for both devices, which is not possible.
This causes a NULL error to show up in video_open and mpeg_open.
-Mark
Iterations through the cx23885_devlist must check for NULL
pointers as some supported devices only have DVB support at the moment.
Mark Jenks encoutered an Oops in a system with both an HVR-1250 and HVR-1800
installed.

commit b36a50f92d1c4300a88f606b4d2bbdc4f442a2d7 upstream.
Looking at the source, there seems to be a missing * to match my DMI
string. I mean for newer IBM and Lenovo's laptops you match either one
of the following:
MODULE_ALIAS("dmi:bvnIBM:*:svnIBM:*:pvrThinkPad*:rvnIBM:*");
MODULE_ALIAS("dmi:bvnLENOVO:*:svnLENOVO:*:pvrThinkPad*:rvnLENOVO:*");
While for older Thinkpads, you do this (for instance):
IBM_BIOS_MODULE_ALIAS("1[0,3,6,8,A-G,I,K,M-P,S,T]");
with IBM_BIOS_MODULE_ALIAS being MODULE_ALIAS("dmi:bvnIBM:bvr" __type "ET??WW")
Note there's no * terminating the string. As result, udev doesn't load
anything because modprobe cannot find anything matching this (my
machine actually):
udevtest: run: '/sbin/modprobe dmi:bvnIBM:bvr1IET71WW(2.10):bd06/16/2006:svnIBM:pn236621U:pvrNotAv

commit bc0fd67feba2e0770aad85393500ba77c6489f1c upstream.
When renaming a mapped device validate the length of the new name.
The rename ioctl accepted any correctly-terminated string enclosed
within the data passed from userspace. The other ioctls enforce a
size limit of DM_NAME_LEN. If the name is changed and becomes longer
than that, the device can no longer be addressed by name.
Fix it by properly checking for device name length (including
terminating zero).

commit b2174eebd1fadb76454dad09a1dacbc17081e6b0 upstream.
In the async encryption-complete function (kcryptd_async_done), the
crypto_async_request passed in may be different from the one passed to
crypto_ablkcipher_encrypt/decrypt. Only crypto_async_request->data is
guaranteed to be same as the one passed in. The current
kcryptd_async_done uses the passed-in crypto_async_request directly
which may cause the AES-NI-based AES algorithm implementation to panic.
This patch fixes this bug by only using crypto_async_request->data,
which points to dm_crypt_request, the crypto_async_request passed in.
The original data (convert_context) is gotten from dm_crypt_request.

commit e9c1670c2a14ef9cc20d86b24b829f3947aad34e upstream.
Samsung DB-P70 somehow botched the first ICH9 SATA port. The board
doesn't expose the first port but somehow SStatus reports link online
while failing SRST protocol leading to repeated probe failures and
thus long boot delay.
Because the BIOS doesn't carry any identifying DMI information, the
port can't be blacklisted safely. Fortunately, the controller does
have subsystem vendor and ID set. It's unclear whether the subsystem
IDs are used only for the board but it can be safely worked around by
disabling SIDPR access and just using SRST works around the problem.
Even when the workaround is triggered on an unaffected board the only
side effect will be missing SCR access.

acpi_namespace_node's name.ascii field is four chars, and not NULL-

a length restriction.
This is the minimal fix for both stable 2.6.27 and 2.6.28.

(cherry picked from commit ac9575f75c52bcb455120f8c43376b556acba048)
The video_ioctl2 conversion of ivtv in kernel 2.6.27 introduced a bug
causing decoder commands to crash. The decoder commands should have been
handled from the video_ioctl2 default handler, ensuring correct mapping
of the argument between user and kernel space. Unfortunately they ended
up before the video_ioctl2 call, causing random crashes.

cause!

(cherry picked from commit 67e70baf043cfdcdaf5972bc94be82632071536b)
Just like with the s5h1411, the s5h1409 needs a soft-reset in order for it
to know that the tuner has been told to change frequencies. This change
changes the behavior from "random tuning times between 500ms to complete
tuning lock failures" to "tuning lock consistently within 700ms".

commit 9e973e64ac6dc504e6447d52193d4fff1a670156 upstream.
On occasion, the request will apparently have more segments than we
fit into the ring. Jens says:
> The second problem is that the block layer then appears to create one
> too many segments, but from the dump it has rq->nr_phys_segments ==
> BLKIF_MAX_SEGMENTS_PER_REQUEST. I suspect the latter is due to
> xen-blkfront not handling the merging on its own. It should check that
> the new page doesn't form part of the previous page. The
> rq_for_each_segment() iterates all single bits in the request, not dma
> segments. The "easiest" way to do this is to call blk_rq_map_sg() and
> then iterate the mapped sg list. That will give you what you are
> looking for.
> Here's a test patch, compiles but otherwise untested. I spent more
> time figuring out how to enable XEN than to code it up, so YMMV!
> Probably the sg list wants to be put inside the ring and only
> initialized on allocation, then you can get rid of the sg on stack and
> sg_init_table() loop call in the function. I'll leave that, and the
> testing, to you.

commit 9aa09d2f8f4bc440d6db1c3414d4009642875240 upstream.
Currently ITDs are immediately recycled whenever their URB completes.
However, EHCI hardware can sometimes remember some ITD state. This
means that when the ITD is reused before end-of-frame it may sometimes
cause the hardware to reference bogus state.
This patch defers reusing such ITDs by moving them into a new ehci member
cached_itd_list. ITDs resting in cached_itd_list are moved back into their
stream's free_list once scan_periodic() detects that the active frame has
elapsed.
This makes the snd_usb_us122l driver (in kernel since .28) work right
when it's hooked up through EHCI.

Fix the led device naming for the sdhci driver.
The led class documentation defines the led name to have the
form "devicename:colour:function" while not applicable sections
should be left blank.
To comply with the documentation the led device name is changed
from "mmc*" to "mmc*::".

commit c12e56ef6951f4fce1afe9ef6aab9243ea9a9b04 upstream.
STag zero is a special STag that allows consumers to access any bus
address without registering memory. The nes driver unfortunately
allows STag zero to be used even with QPs created by unprivileged
userspace consumers, which means that any process with direct verbs
access to the nes device can read and write any memory accessible to
the underlying PCI device (usually any memory in the system). Such
access is usually given for cluster software such as MPI to use, so
this is a local privilege escalation bug on most systems running this
driver.
The driver was using STag zero to receive the last streaming mode
data; to allow STag zero to be disabled for unprivileged QPs, the
driver now registers a special MR for this data.

commit 1f9f13c8d59c1d8da1a602b71d1ab96d1d37d69e upstream.
The PCIe port driver currently sets the PCIe AER error reporting bits for
any root or switch port without first checking to see if firmware will grant
control. This patch moves setting these bits to the AER service driver
aer_enable_port routine. The bits are then set for the root port and any
downstream switch ports after the check for firmware support (aer_osc_setup)
is made. The patch also unsets the bits in a similar fashion when the AER
service driver is unloaded.

commit 649426efcfbc67a8b033497151816cbac9fd0cfa upstream.
This patch is intended to disable L0s ASPM link state for 82598 (ixgbe)
parts due to the fact that it is possible to corrupt TX data when coming
back out of L0s on some systems. The workaround had been added for 82575
(igb) previously, but did not use the ASPM api. This quirk uses the ASPM
api to prevent the ASPM subsystem from re-enabling the L0s state.
Instead of adding the fix in igb to the ixgbe driver as well it was
decided to move it into a pci quirk. It is necessary to move the fix out
of the driver and into a pci quirk in order to prevent the issue from
occuring prior to driver load to handle the possibility of the device being
passed to a VM via direct assignment.

commit 09b4068a7fe442efc40e9dcbcf5ff37c3338ab15 upstream.
When doing recovery on a raid10 with a write-intent bitmap, we only
need to recovery chunks that are flagged in the bitmap.
However if we choose to skip a chunk as it isn't flag, the code
currently skips the whole raid10-chunk, thus it might not recovery
some blocks that need recovering.
This patch fixes it.
In case that is confusing, it might help to understand that there
is a 'raid10 chunk size' which guides how data is distributed across
the devices, and a 'bitmap chunk size' which says how much data
corresponds to a single bit in the bitmap.
This bug only affects cases where the bitmap chunk size is smaller
than the raid10 chunk size.

commit 78200d45cde2a79c0d0ae0407883bb264caa3c18 upstream.
For raid1/4/5/6, resync (fixing inconsistencies between devices) is
very similar to recovery (rebuilding a failed device onto a spare).
The both walk through the device addresses in order.
For raid10 it can be quite different. resync follows the 'array'
address, and makes sure all copies are the same. Recover walks
through 'device' addresses and recreates each missing block.
The 'bitmap_cond_end_sync' function allows the write-intent-bitmap
(When present) to be updated to reflect a partially completed resync.
It makes assumptions which mean that it does not work correctly for
raid10 recovery at all.
In particularly, it can cause bitmap-directed recovery of a raid10 to
not recovery some of the blocks that need to be recovered.
So move the call to bitmap_cond_end_sync into the resync path, rather
than being in the common "resync or recovery" path.

commit 73d5c38a9536142e062c35997b044e89166e063b upstream.
There has been a race in raid10 and raid1 for a long time
which has only recently started showing up due to a scheduler changed.
When a sync_read request finishes, as soon as reschedule_retry
is called, another thread can mark the resync request as having
completed, so md_do_sync can finish, ->stop can be called, and
->conf can be freed. So using conf after reschedule_retry is not
safe.
Similarly, when finishing a sync_write, calling md_done_sync must be
the last thing we do, as it allows a chain of events which will free
conf and other data structures.
The first of these requires action in raid10.c
The second requires action in raid1.c and raid10.c

commit d6515e6ff4ad3db4bd5ef2dd4e1026a7aca2482e upstream.
When SCR access is available and the link is offline, softreset is
skipped as it only wastes time and some controllers don't respond very
well. However, the skip path forgot to thaw the port, which not only
blocks further event notification from the port but also causes
repeated EH invocations on the same event on drivers which rely on
->thaw() to clear events if the IRQ is shared with another device or
port.
This problem has always been there but is uncovered by recent sata_nv
nf2/3 change which dropped hardreset support while maintaining SCR
access. nf2/3 doesn't clear hotplug event mask from the interrupt
handler but relies on ->thaw() to clear them. When the hardreset was
there, the reset action was never skipped and the port was always
thawed but, with the hardreset gone, ->prereset() determines that
there's no need for softreset and both ->softreset() and ->thaw() are
skipped. This leads to stuck hotplug event in the IRQ status register
triggering hotplug event whenever IRQ is delieverd on the same IRQ.
As the controller shares the same IRQ for both ports, this happens on
every IO if one port is occpupied and the other isn't.
This patch fixes the problem by making sure that the port is thawed on
reset-skip path.
bko#11615 reports this problem.

commit 968e594afdbc40b4270f9d4032ae8350475749d6 upstream.
Hanno Böck reported a problem where an old Conner CP30254 240MB hard drive
was reported as 1.1TB in capacity by libata:
http://lkml.org/lkml/2009/2/13/134
This was caused by libata trusting the drive's reported current capacity in
sectors in identify words 57 and 58 if the drive does not support LBA and the
current CHS translation values appear valid. Unfortunately it seems older
ATA specs were vague about what this field should contain and a number of drives
used values with wrong byte order or that were totally bogus. There's no
unique information that it conveys and so we can just calculate the number
of sectors from the reported current CHS values.
While we're at it, clean up this function to use named constants for the
identify word values.
