commit 8c5bcded11cb607b1bb5920de3b9c882136d27db upstream.
The Tevii S480 outputs 18V on startup for the LNB supply voltage and does not
automatically power down. This blocks other receivers connected
to a satellite channel router (EN50494), since the receivers can not send the
required DiSEqC sequences when the Tevii card is connected to a the same SCR.
This patch switches off the LNB supply voltage on initialization of the frontend.

properly on streaming stop
commit 627530c32a43283474e9dd3e954519410ffa033a upstream.
When a new video frame is started, the driver takes the next video buffer from
the list of active buffers and moves it to dev->usb_ctl.vid_buf / dev->usb_ctl.vbi_buf
for further processing.
On streaming stop we currently only give back the pending buffers from the list
but not the ones which are currently processed.
This causes the following warning from the vb2 core since kernel 3.15:

commit 3bacc10cd4a85bc70bc0b6c001d3bf995c7fe04c upstream.
Fix clamp_align() used in v4l_bound_align_image() to prevent overflow
when passed large value like UINT32_MAX.
In the current implementation:
clamp_align(UINT32_MAX, 8, 8192, 3)
returns 8, because in line:
x = (x + (1 << (align - 1))) & mask;
x overflows to (-1 + 4) & 0x7 = 3, while expected value is 8192.
v4l_bound_align_image() is heavily used in VIDIOC_S_FMT and
VIDIOC_SUBDEV_S_FMT ioctls handlers, and documentation of the latter
explicitly states that:
"The modified format should be as close as possible to the original
request."
-- http://linuxtv.org/downloads/v4l-dvb-apis/vidioc-subdev-g-fmt.html
Thus one would expect, that passing UINT32_MAX as format width and
height will result in setting maximum possible resolution for the
device. Particularly, when the driver doesn't support
VIDIOC_ENUM_FRAMESIZES ioctl, which is common in the codebase.

commit b478e336b3e75505707a11e78ef8b964ef0a03af upstream.
The current error path calls tilcdc_unload() in case of an error to release
the resources. However, this is wrong because not all resources have been
allocated by the time an error occurs in tilcdc_load().
To fix it, this commit adds proper labels to bail out at the different
stages in the load function, and release only the resources actually allocated.

commit f74a289b9480648a654e5afd8458c2263c03a1e1 upstream.
The framebuffer code uses the current background color to fill the border
when switching consoles, however, this results in inconsistent behavior.
For example:
- start Midnigh Commander
- the border is black
- switch to another console and switch back
- the border is cyan
- type something into the command line in mc
- the border is cyan
- switch to another console and switch back
- the border is black
- press F9 to go to menu
- the border is black
- switch to another console and switch back
- the border is dark blue
When switching to a console with Midnight Commander, the border is random
color that was left selected by the slang subsystem.
This patch fixes this inconsistency by always using black as the
background color when switching consoles.

commit 82cfb90bc99d7b7e0ec62d0505b9d4f06805d5db upstream.
Commit 98683650 "Merge branch 'drbd-8.4_ed6' into
for-3.8-drivers-drbd-8.4_ed6" switches to the new augment API, but the
new API requires that the tree is augmented before rb_insert_augmented()
is called, which is missing.
So we add the augment-code to drbd_insert_interval() when it travels the
tree up to down before rb_insert_augmented(). See the example in
include/linux/interval_tree_generic.h or Documentation/rbtree.txt.
drbd_insert_interval() may cancel the insertion when traveling, in this
case, the just added augment-code does nothing before cancel since the
@this node is already in the subtrees in this case.

commit eb76faf53b1ff7a77ce3f78cc98ad392ac70c2a0 upstream.
The 'last_accessed' member of the dm_buffer structure was only set when
the the buffer was created. This led to each buffer being discarded
after dm_bufio_max_age time even if it was used recently. In practice
this resulted in all thinp metadata being evicted soon after being read
-- this is particularly problematic for metadata intensive workloads
like multithreaded small random IO.
'last_accessed' is now updated each time the buffer is moved to the head
of the LRU list, so the buffer is now properly discarded if it was not
used in dm_bufio_max_age time.

commit 6fbc198cf623944ab60a1db6d306a4d55cdd820d upstream.
On restore, virtio pci does the following:
+ set features
+ init vqs etc - device can be used at this point!
+ set ACKNOWLEDGE,DRIVER and DRIVER_OK status bits
This is in violation of the virtio spec, which
requires the following order:
- ACKNOWLEDGE
- DRIVER
- init vqs
- DRIVER_OK
This behaviour will break with hypervisors that assume spec compliant
behaviour. It seems like a good idea to have this patch applied to
stable branches to reduce the support butden for the hypervisors.

commit d4c5efdb97773f59a2b711754ca0953f24516739 upstream.
zatimend has reported that in his environment (3.16/gcc4.8.3/corei7)
memset() calls which clear out sensitive data in extract_{buf,entropy,
entropy_user}() in random driver are being optimized away by gcc.
Add a helper memzero_explicit() (similarly as explicit_bzero() variants)
that can be used in such cases where a variable with sensitive data is
being cleared out in the end. Other use cases might also be in crypto
code. [ I have put this into lib/string.c though, as it's always built-in
and doesn't need any dependencies then. ]

commit 24dff96a37a2ca319e75a74d3929b2de22447ca6 upstream.
we used to check for "nobody else could start doing anything with
that opened file" by checking that refcount was 2 or less - one
for descriptor table and one we'd acquired in fget() on the way to
wherever we are. That was race-prone (somebody else might have
had a reference to descriptor table and do fget() just as we'd
been checking) and it had become flat-out incorrect back when
we switched to fget_light() on those codepaths - unlike fget(),
it doesn't grab an extra reference unless the descriptor table
is shared. The same change allowed a race-free check, though -
we are safe exactly when refcount is less than 2.
It was a long time ago; pre-2.6.12 for ioctl() (the codepath leading
to ppp one) and 2.6.17 for sendmsg() (netlink one). OTOH,
netlink hadn't grown that check until 3.9 and ppp used to live
in drivers/net, not drivers/net/ppp until 3.1. The bug existed
well before that, though, and the same fix used to apply in old
location of file.

commit d1419d50c1bf711e9fd27b516a739c86b23f7cf9 upstream.
Current code erroneously fill the last byte of R2 response with an undefined
value. In addition, the controller actually 'offloads' the last byte
(CRC7, end bit) while receiving R2 response and thus it's impossible to get the
actual value. This could cause mmc stack to obtain inconsistent CID from the
same card after resume and misidentify it as a different card.
Fix by assigning dummy CRC and end bit: {7'b0, 1} = 0x1 to the last byte of R2.

But that also skips ata_sff_dev_classify required for device detection.

lspci shows that the driver used for the Broadcom OSB4 IDE Controller is
pata_serverworks:
00:0f.1 IDE interface: Broadcom OSB4 IDE Controller (prog-if 8e [Master SecP SecO PriP])
Flags: bus master, medium devsel, latency 64
[virtual] Memory at 000001f0 (32-bit, non-prefetchable) [size=8]

Kernel driver in use: pata_serverworks
The pata_serverworks driver supports five distinct device IDs,
one being the OSB4 and the other four belonging to the CSB series.
The CSB series appears to support 64-KB DMA transfers,
as tests on a machine with an SAI2 motherboard
containing a Broadcom CSB5 IDE Controller (vendor and device IDs: 1166:0212)
showed no problems with 64-KB DMA transfers.
This problem was first discovered when attempting to install openSUSE
from a DVD on a machine with an STL2 motherboard.
Using the pata_serverworks module,
older releases of openSUSE will not install at all due to the timeouts.
Releases of openSUSE prior to 11.3 can be installed by disabling
the pata_serverworks module using the brokenmodules boot parameter,
which causes the serverworks module to be used instead.
Recent releases of openSUSE (12.2 and later) include better error recovery and
will install, though very slowly.
On all openSUSE releases, the problem can be recreated
on a machine containing a Broadcom OSB4 IDE Controller
by mounting an install DVD and running a command similar to the following:
find /mnt -type f -print | xargs cat > /dev/null
The patch below corrects the problem.
Similar to the other ATA drivers that do not support 64-KB DMA transfers,
the patch changes the ata_port_operations qc_prep vector to point to a routine
that breaks any 64-KB segment into two 32-KB segments and
changes the scsi_host_template sg_tablesize element to reduce by half
the number of scatter/gather elements allowed.
These two changes affect only the OSB4.

[ Upstream commit 95ff88688781db2f64042e69bd499e518bbb36e5 ]
The following patch fixes a bug which causes the ax88179_178a driver to be
incapable of being added to a bond.
When I brought up the issue with the bonding maintainers, they indicated
that the real problem was with the NIC driver which must return zero for
success (of setting the MAC address). I see that several other NIC drivers
follow that pattern by either simply always returing zero, or by passing
through a negative (error) result while rewriting any positive return code
to zero. With that same philisophy applied to the ax88179_178a driver, it
allows it to work correctly with the bonding driver.
I believe this is suitable for queuing in -stable, as it's a small, simple,
and obvious fix that corrects a defect with no other known workaround.
This patch is against vanilla 3.17(.0).

commit 4807b51895dce8aa650ebebc51fa4a795ed6b8b8 upstream.
In this expression: seq = (seq - 1) % 8
seq (u8) is implicitly converted to an int in the arithmetic operation.
So if seq value is 0, operation is ((0 - 1) % 8) => (-1 % 8) => -1.
The new seq value is 0xff which is an invalid ACK value, we expect 0x07.
It leads to frequent dropped ACK and retransmission.
Fix this by using '&' binary operator instead of '%'.

commit 89ec3dcf17fd3fa009ecf8faaba36828dd6bc416 upstream.
Some implementations of modprobe fail to load the driver for a PCI device
automatically because the "interface" part of the modalias from the kernel
is lowercase, and the modalias from file2alias is uppercase.
The "interface" is the low-order byte of the Class Code, defined in PCI
r3.0, Appendix D. Most interface types defined in the spec do not use
alpha characters, so they won't be affected. For example, 00h, 01h, 10h,
20h, etc. are unaffected.
Print the "interface" byte of the Class Code in uppercase hex, as we
already do for the Vendor ID, Device ID, Class, etc.

commit 9fe373f9997b48fcd6222b95baf4a20c134b587a upstream.
The Crocodile chip occasionally comes up with 4k and 8k BAR sizes. Due to
an erratum, setting the SR-IOV page size causes the physical function BARs
to expand to the system page size. Since ppc64 uses 64k pages, when Linux
tries to assign the smaller resource sizes to the now 64k BARs the address
will be truncated and the BARs will overlap.
Force Linux to allocate the resource as a full page, which avoids the
overlap.
