commit c8760069627ad3b0dbbea170f0c4c58b16e18d3d upstream.
Current MMC driver doesn't handle generic error (bit19 of device
status) in write sequence. As a result, write data gets lost when
generic error occurs. For example, a generic error when updating a
filesystem management information causes a loss of write data and
corrupts the filesystem. In the worst case, the system will never
boot.
This patch includes the following functionality:
1. To enable error checking for the response of CMD12 and CMD13
in write command sequence
2. To retry write sequence when a generic error occurs
Messages are added for v2 to show what occurs.

commit b4789b8e6be3151a955ade74872822f30e8cd914 upstream.
It appears that driver runs into a problem here if fibsize is too small
because we allocate user_srbcmd with fibsize size only but later we
access it until user_srbcmd->sg.count to copy it over to srbcmd.
It is not correct to test (fibsize < sizeof(*user_srbcmd)) because this
structure already includes one sg element and this is not needed for
commands without data. So, we would recommend to add the following
(instead of test for fibsize == 0).

commit a497e47d4aec37aaf8f13509f3ef3d1f6a717d88 upstream.
If we do a zero size allocation then it will oops. Also we can't be
sure the user passes us a NUL terminated string so I've added a
terminator.
This code can only be triggered by root.

commit 8821f5dc187bdf16cfb32ef5aa8c3035273fa79a upstream.
When working on report indexes, always validate that they are in bounds.
Without this, a HID device could report a malicious feature report that
could trick the driver into a heap overflow:
[ 634.885003] usb 1-1: New USB device found, idVendor=0596, idProduct=0500
...
[ 676.469629] BUG kmalloc-192 (Tainted: G W ): Redzone overwritten
Note that we need to change the indexes from s8 to s16 as they can
be between -1 and 255.

[ Upstream commit f3d3342602f8bcbf37d7c46641cb9bca7618eb1c ]
This patch now always passes msg->msg_namelen as 0. recvmsg handlers must
set msg_namelen to the proper size <= sizeof(struct sockaddr_storage)
to return msg_name to the user.
This prevents numerous uninitialized memory leaks we had in the
recvmsg handlers and makes it harder for new code to accidentally leak
uninitialized memory.
Optimize for the case recvfrom is called with NULL as address. We don't
need to copy the address at all, so set it to NULL before invoking the
recvmsg handler. We can do so, because all the recvmsg handlers must
cope with the case a plain read() is called on them. read() also sets
msg_name to NULL.
Also document these changes in include/linux/net.h as suggested by David
Miller.
Changes since RFC:
Set msg->msg_name = NULL if user specified a NULL in msg_name but had a
non-null msg_namelen in verify_iovec/verify_compat_iovec. This doesn't
affect sendto as it would bail out earlier while trying to copy-in the
address. It also more naturally reflects the logic by the callers of
verify_iovec.
With this change in place I could remove "
if (!uaddr || msg_sys->msg_namelen == 0)
msg->msg_name = NULL
".
This change does not alter the user visible error logic as we ignore
msg_namelen as long as msg_name is NULL.
Also remove two unnecessary curly brackets in ___sys_recvmsg and change
comments to netdev style.

[ Upstream commit 1ca1a4cf59ea343a1a70084fe7cc96f37f3cf5b1 ]
In af3e095a1fb4, Erik Jacobsen fixed one type of unaligned access
bug for ia64 by converting a 64-bit write to use put_unaligned().
Unfortunately, since gcc will convert a short memset() to a series
of appropriately-aligned stores, the problem is now visible again
on tilegx, where the memset that zeros out proc_event is converted
to three 64-bit stores, causing an unaligned access panic.
A better fix for the original problem is to ensure that proc_event
is aligned to 8 bytes here. We can do that relatively easily by
arranging to start the struct cn_msg aligned to 8 bytes and then
offset by 4 bytes. Doing so means that the immediately following
proc_event structure is then correctly aligned to 8 bytes.
The result is that the memset() stores are now aligned, and as an
added benefit, we can remove the put_unaligned() calls in the code.

This patch fixes two race conditions between bond_store_updelay/downdelay
and bond_store_miimon which could lead to division by zero as miimon can
be set to 0 while either updelay/downdelay are being set and thus miss the
zero check in the beginning, the zero div happens because updelay/downdelay
are stored as new_value / bond->params.miimon. Use rtnl to synchronize with
miimon setting.

commit 33a7ab91d509fa33b4bcd3ce0038cc80298050da upstream.
The W83L786NG stores the fan speed on 4 bits while the sysfs interface
uses a 0-255 range. Thus the driver should scale the user input down
to map it to the device range, and scale up the value read from the
device before presenting it to the user. The reserved register nibble
should be left unchanged.

commit 4cb57ab4a2e61978f3a9b7d4f53988f30d61c27f upstream.
Some module parameters in dm-bufio are read-only. These parameters
inform the user about memory consumption. They are not supposed to be
changed by the user.
However, despite being read-only, these parameters can be set on
modprobe or insmod command line, for example:
modprobe dm-bufio current_allocated_bytes=12345
The kernel doesn't expect that these variables can be non-zero at module
initialization and if the user sets them, it results in BUG.
This patch initializes the variables in the module init routine, so that
user-supplied values are ignored.

commit 230c83afdd9cd384348475bea1e14b80b3b6b1b8 upstream.
There is a possible leak of snapshot space in case of crash.
The reason for space leaking is that chunks in the snapshot device are
allocated sequentially, but they are finished (and stored in the metadata)
out of order, depending on the order in which copying finished.
For example, supposed that the metadata contains the following records
SUPERBLOCK
METADATA (blocks 0 ... 250)
DATA 0
DATA 1
DATA 2
...
DATA 250
Now suppose that you allocate 10 new data blocks 251-260. Suppose that
copying of these blocks finish out of order (block 260 finished first
and the block 251 finished last). Now, the snapshot device looks like
this:
SUPERBLOCK
METADATA (blocks 0 ... 250, 260, 259, 258, 257, 256)
DATA 0
DATA 1
DATA 2
...
DATA 250
DATA 251
DATA 252
DATA 253
DATA 254
DATA 255
METADATA (blocks 255, 254, 253, 252, 251)
DATA 256
DATA 257
DATA 258
DATA 259
DATA 260
Now, if the machine crashes after writing the first metadata block but
before writing the second metadata block, the space for areas DATA 250-255
is leaked, it contains no valid data and it will never be used in the
future.
This patch makes dm-snapshot complete exceptions in the same order they
were allocated, thus fixing this bug.
Note: when backporting this patch to the stable kernel, change the version
field in the following way:
* if version in the stable kernel is {1, 11, 1}, change it to {1, 12, 0}
* if version in the stable kernel is {1, 10, 0} or {1, 10, 1}, change it
to {1, 10, 2}
Userspace reads the version to determine if the bug was fixed, so the
version change is needed.

commit 1aeef303b5d9e243c41d5b80f8bb059366514a10 upstream.
For MPC8572/MPC8536, the status of GPIOs defined as output
cannot be determined by reading GPDAT register, so the code
use shadow data register instead. But the code may give the
wrong status of GPIOs defined as input under some scenarios:
1. If some pins were configured as inputs and were asserted
high before booting the kernel, the shadow data has been
initialized with those pin values.
2. Some pins have been configured as output first and have
been set to the high value, then reconfigured as input.
The above cases will make the shadow data for those input
pins to be set to high. Then reading the pin status will
always return high even if the actual pin status is low.
The code should eliminate the effects of the shadow data to
the input pins, and the status of those pins should be
read directly from GPDAT.

commit 8704211f65a2106ba01b6ac9727cdaf9ca11594c upstream.
FTDI UARTs support only 7 or 8 data bits. Until now the ftdi_sio driver would
only report this limitation for CS6 to dmesg and fail to reflect this fact to
tcgetattr.
This patch reverts the unsupported CSIZE setting and reports the fact with less
severance to dmesg for both CS5 and CS6.
To test the patch it's sufficient to call
stty -F /dev/ttyUSB0 cs5
which will succeed without the patch and report an error with the patch
applied.
As an additional fix this patch ensures that the control request will always
include a data bit size.

commit 88bf6d62db4393fa03a58bada9d746312d5b496f upstream.
A return value of 1 is interpreted as an error. See pci_driver.
in local_pci_probe(). If you're wondering how this ever could
have worked, it's because it used to be the case that only return
values less than zero were interpreted as failure. But even in
the current kernel if the driver registers its various entry
points with the kernel, and then returns a value which is
interpreted as failure, those registrations aren't undone, so
the driver still mostly works. However, the driver's remove
function wouldn't be called on rmmod, and pci power management
functions wouldn't work. In the case of Smart Array, since it
has a battery backed cache (or else no cache) even if the driver
is not shut down properly as long as there is no outstanding
i/o, nothing too bad happens, which is why it took so long to
notice.
Requesting backport to stable because the change to pci-driver.c
which requires driver probe functions to return 0 occurred between
2.6.35 and 2.6.36 (the pci power management breakage) and again
between 3.7 and 3.8 (pci_dev->driver getting set to NULL in
local_pci_probe() preventing driver remove function from being
called on rmmod.)

Kernel panic - not syncing: Fatal exception in interrupt
This is because the macro operations in smc91x.h defined
for Versatile are missing SMC_outsw() as used in this
commit.
The Versatile needs and uses the same accessors as the other
platforms in the first if(...) clause, just switch it to using
that and we have one problem less to worry about.
This includes a hunk of a patch from Will Deacon fixin
the other 32bit platforms as well: Innokom, Ramses, PXA,
PCM027.
Checkpatch complains about spacing, but I have opted to

commit ae5fbae0ccd982dfca0ce363036ed92f5b13f150 upstream.
Since commit 110dd8f19df5 "[SCSI] libsas: fix scr_read/write users and
update the libata documentation" we have been passing pmp=1 and is_cmd=0
to ata_tf_to_fis(). Praveen reports that eSATA attached drives do not
discover correctly. His investigation found that the BIOS was passing
pmp=0 while Linux was passing pmp=1 and failing to discover the drives.
Update libsas to follow the libata example of pulling the pmp setting
from the ata_link and correct is_cmd to be 1 since all tf's submitted
through ->qc_issue are commands. Presumably libsas lldds do not care
about is_cmd as they have sideband mechanisms to perform link
management.

commit 2fea6cd303c0d0cd9067da31d873b6a6d5bd75e7 upstream.
This patch fixes the issue that the sja1000_interrupt() function may have
returned IRQ_NONE without processing the optional pre_irq() and post_irq()
function before. Further the irq processing counter 'n' is moved to the end of
the while statement to return correct IRQ_[NONE|HANDLED] values at error
conditions.

commit 46a51c80216cb891f271ad021f59009f34677499 upstream.
This patch fixes the bug in reset_store caused by accessing NULL pointer.
The bdev gets its value from bdget_disk() which could fail when memory
pressure is severe and hence can return NULL because allocation of
inode in bdget could fail.
Hence, this patch introduces a check for bdev to prevent reference to a
NULL pointer in the later part of the code. It also removes unnecessary
check of bdev for fsync_bdev().

The dwc3 UDC driver doesn't implement endpoint wedging correctly.
When an endpoint is wedged, the gadget driver should be allowed to
clear the wedge by calling usb_ep_clear_halt(). Only the host is
prevented from resetting the endpoint.

commit 6f6485463aada1ec6a0f3db6a03eb8e393d6bb55 upstream.
Fix race in generic write implementation, which could lead to
temporarily degraded throughput.
The current generic write implementation introduced by commit
27c7acf22047 ("USB: serial: reimplement generic fifo-based writes") has
always had this bug, although it's fairly hard to trigger and the
consequences are not likely to be noticed.
Specifically, a write() on one CPU while the completion handler is
running on another could result in only one of the two write urbs being
utilised to empty the remainder of the write fifo (unless there is a
second write() that doesn't race during that time).

In iSCSI negotiations with initiator CHAP enabled, usernames with

e.g. "usernameXXXXX" will be permitted to match "username".
Just check one more byte so the trailing null char is also matched.

commit e7cc5cf74544d97d7b69e2701595037474db1f96 upstream.
The pcie_portdrv .probe() method calls pci_enable_device() once, in
pcie_port_device_register(), but the .remove() method calls
pci_disable_device() twice, in pcie_port_device_remove() and in
pcie_portdrv_remove().
That causes a "disabling already-disabled device" warning when removing a
PCIe port device. This happens all the time when removing Thunderbolt
devices, but is also easy to reproduce with, e.g.,
"echo 0000:00:1c.3 > /sys/bus/pci/drivers/pcieport/unbind"
This patch removes the disable from pcie_portdrv_remove().

Apparently they need the same treatment as primary planes. This fixes
modesetting failures because of stuck cursors (!) on Thomas' i830M

I've figured while at it I'll also roll it out for the ivb 3 pipe
version of this function. I didn't do this for i845/i865 since Bspec
says the update mechanism works differently, and there's some
additional rules about what can be updated in which order.
