commit d90db4b12bc1b9b8a787ef28550fdb767ee25a49 upstream.
When downloading firmware into the device, the driver fails to check the
return when allocating an skb. When the allocation fails, a BUG can be
generated, as seen in https://bugzilla.redhat.com/show_bug.cgi?id=771656.

commit eb31aae8cb5eb54e234ed2d857ddac868195d911 upstream.
Some Dell BIOSes have MCFG tables that don't report the entire
MMCONFIG area claimed by the chipset. If we move PCI devices into
that claimed-but-unreported area, they don't work.
This quirk reads the AMD MMCONFIG MSRs and adds PNP0C01 resources as
needed to cover the entire area.
Example problem scenario:
BIOS-e820: 00000000cfec5400 - 00000000d4000000 (reserved)
Fam 10h mmconf [d0000000, dfffffff]
PCI: MMCONFIG for domain 0000 [bus 00-3f] at [mem 0xd0000000-0xd3ffffff] (base 0xd0000000)
pnp 00:0c: [mem 0xd0000000-0xd3ffffff]
pci 0000:00:12.0: reg 10: [mem 0xffb00000-0xffb00fff]
pci 0000:00:12.0: no compatible bridge window for [mem 0xffb00000-0xffb00fff]

commit 307729c8bc5b5a41361af8af95906eee7552acb1 upstream.
We normally try to avoid reading from write-mostly devices, but when
we do we really have to check for bad blocks and be sure not to
try reading them.
With the current code, best_good_sectors might not get set and that
causes zero-length read requests to be send down which is very
confusing.
This bug was introduced in commit d2eb35acfdccbe2 and so the patch
is suitable for 3.1.x and 3.2.x

commit 9e7860cee18241633eddb36a4c34c7b61d8cecbc upstream.
Haogang Chen found out that:
There is a potential integer overflow in process_msg() that could result
in cross-domain attack.
body = kmalloc(msg->hdr.len + 1, GFP_NOIO | __GFP_HIGH);
When a malicious guest passes 0xffffffff in msg->hdr.len, the subsequent
call to xb_read() would write to a zero-length buffer.
The other end of this connection is always the xenstore backend daemon
so there is no guest (malicious or otherwise) which can do this. The
xenstore daemon is a trusted component in the system.
However this seem like a reasonable robustness improvement so we should
have it.
And Ian when read the API docs found that:
The payload length (len field of the header) is limited to 4096
(XENSTORE_PAYLOAD_MAX) in both directions. If a client exceeds the
limit, its xenstored connection will be immediately killed by
xenstored, which is usually catastrophic from the client's point of
view. Clients (particularly domains, which cannot just reconnect)
should avoid this.
so this patch checks against that instead.
This also avoids a potential integer overflow pointed out by Haogang Chen.

commit aff132d95ffe14eca96cab90597cdd010b457af7 upstream.
The amount of memory required for tracking chain buffers is rather
large, and when the host credit count is big, memory allocation
failure occurs inside __get_free_pages.
The fix is to limit the number of chains to 100,000. In addition,
the number of host credits is limited to 30,000 IOs. However this
limitation can be overridden this using the command line option
max_queue_depth. The algorithm for calculating the
reply_post_queue_depth is changed so that it is equal to
(reply_free_queue_depth + 16), previously it was (reply_free_queue_depth * 2).

commit 30c43282f3d347f47f9e05199d2b14f56f3f2837 upstream.
Added code to release the spinlock that is used to protect the
raid device list before calling a function that can block. The
blocking was causing a reschedule, and subsequently it is tried
to acquire the same lock, resulting in a panic (NMI Watchdog
detecting a CPU lockup).

commit a776c491ca5e38c26d9f66923ff574d041e747f4 upstream.
I traced a nasty kexec on panic boot failure to the fact that we had
screaming msi interrupts and we were not disabling the msi messages at
kernel startup. The booting kernel had not enabled those interupts so
was not prepared to handle them.
I can see no reason why we would ever want to leave the msi interrupts
enabled at boot if something else has enabled those interrupts. The pci
spec specifies that msi interrupts should be off by default. Drivers
are expected to enable the msi interrupts if they want to use them. Our
interrupt handling code reprograms the interrupt handlers at boot and
will not be be able to do anything useful with an unexpected interrupt.
This patch applies cleanly all of the way back to 2.6.32 where I noticed
the problem.

When we fail to erase a PEB, we free the corresponding erase entry object,
but then re-schedule this object if the error code was something like -EAGAIN.
Obviously, it is a bug to use the object after we have freed it.

commit 3df96909b75835d487a9178761622b0cbd7310d4 upstream.
It would previously write basically random bits to PCI configuration space...
Not very surprising that the GPU tended to stop responding completely. The
resulting MCE even froze the whole machine sometimes.
Now resetting the GPU after a lockup has at least a fighting chance of
succeeding.

commit 342ff28f5a2e5aa3236617bd2bddf6c749677ef2 upstream.
Some error paths in mtd_blkdevs were fixed in the following commit:
commit 94735ec4044a6d318b83ad3c5794e931ed168d10
mtd: mtd_blkdevs: fix error path in blktrans_open
But on these error paths, the block device's `dev->open' count is
already incremented before we check for errors. This meant that, while
the error path was handled correctly on the first time through
blktrans_open(), the device is erroneously considered already open on
the second time through.
This problem can be seen, for instance, when a UBI volume is
simultaneously mounted as a UBIFS partition and read through its
corresponding gluebi mtdblockX device. This results in blktrans_open()
passing its error checks (with `dev->open > 0') without actually having
a handle on the device. Here's a summarized log of the actions and
results with nandsim:
# modprobe nandsim

# modprobe gluebi

BITS_PER_LONG is equal to 32.
If we want to allocate memory for 32 pages with one bit per page then
32 / BITS_PER_LONG is equal to 1 byte that is 8 bits.
To fix it we need to multiply the result by sizeof(unsigned long) equal to 4.

[Not upstream s it was fixed differently there for 3.3 with a much more
"intrusive" rework of the driver - gregkh]
There is a race condition involving acm_tty_hangup() and acm_tty_close()
where hangup() would attempt to access tty->driver_data without proper
locking and NULL checking after close() has potentially already set it
to NULL. One possibility to (sporadically) trigger this behavior is to
perform a suspend/resume cycle with a running WWAN data connection.
This patch addresses the issue by introducing a NULL check for
tty->driver_data in acm_tty_hangup() protected by open_mutex and exiting
gracefully when hangup() is invoked on a device that has already been
closed.

commit f7d9821a6a9c83450ac35e76d3709e32fd38b76f upstream.
If slave device already has a receive handler registered, then the
error unwind of bonding device enslave function is broken.
The following will leave a pointer to freed memory in the slave

# modprobe bonding
# echo +dummy0 >/sys/class/net/bond0/bonding/slaves

commit c61875977458637226ab093a35d200f2d5789787 upstream.
Problems with NVIDIA's OHCI host controllers persist. After looking
carefully through the spec, I finally realized that when a controller
is reset it then automatically goes into a SUSPEND state in which it
is completely quiescent (no DMA and no IRQs) and from which it will
not awaken until the system puts it into the OPERATIONAL state.
Therefore there's no need to worry about controllers being in the
RESET state for extended periods, or remaining in the OPERATIONAL
state during system shutdown. The proper action for device
initialization is to put the controller into the RESET state (if it's
not there already) and then to issue a software reset. Similarly, the
proper action for device shutdown is simply to do a software reset.
This patch (as1499) implements such an approach. It simplifies
initialization and shutdown, and allows the NVIDIA shutdown-quirk code
to be removed.

commit 18b7ede5f7ee2092aedcb578d3ac30bd5d4fc23c upstream.
[ removed the dwc3 portion of the patch as it didn't apply to
older kernels - gregkh]
According to USB 3.0 Specification Table 9-22, if
bmAttributes [4:0] are set to zero, it means "no
streams supported", but the way this helper was
defined on Linux, we will *always* have one stream
which might cause several problems.
For example on DWC3, we would tell the controller
endpoint has streams enabled and yet start transfers
with Stream ID set to 0, which would goof up the host
side.
While doing that, convert the macro to an inline
function due to the different checks we now need.

commit 3c8c9316710b83e906e425024153bf0929887b59 upstream.
Add support for Chinese Noname HSPA USB modem which is apparently
manufactured by a company called ZD Incorporated (based on texts in the

This product is available at least from Dealextreme (SKU 80032) and
possibly in India with name Olive V-MW250. It is based on Qualcomm
MSM6280 chip.
I needed to also add "options usb-storage quirks=0685:7000:i" in modprobe
configuration because udevd or the kernel keeps poking the embedded
fake-cd-rom which fails and causes the device to reset. There might be
a better way to accomplish the same. usb_modeswitch is not needed with
this device.

commit 71d85724bdd947a3b42a88d08af79f290a1a767b upstream.
I encountered a result of COMP_2ND_BW_ERR while improving how the pwc
webcam driver handles not having the full usb1 bandwidth available to
itself.
I created the following test setup, a NEC xhci controller with a
single TT USB 2 hub plugged into it, with a usb keyboard and a pwc webcam
plugged into the usb2 hub. This caused the following to show up in dmesg
when trying to stream from the pwc camera at its highest alt setting:
xhci_hcd 0000:01:00.0: ERROR: unexpected command completion code 0x23.
usb 6-2.1: Not enough bandwidth for altsetting 9
And usb_set_interface returned -EINVAL, which caused my pwc code to not
do the right thing as it expected -ENOSPC.
This patch makes the xhci driver properly handle COMP_2ND_BW_ERR and makes
usb_set_interface return -ENOSPC as expected.
This should be backported to stable kernels as old as 2.6.32.

break dma_unmap_sg() because it requires the original number of entries.

Fix regression introduced by commit 507ca9bc047666 ([PATCH] USB: add
ability for usb-serial drivers to determine if their write urb is
currently being used.) which inverted the logic in write_room so that it
returns zero when the write urb is actually free.

commit 772aed45b604c5ff171f0f12c12392d868333f79 upstream.
In musb_init_controller() there's a pm_runtime_put(), but there's no
pm_runtime_get(), which creates a mismatch that causes the driver to
sleep when it shouldn't.
This was introduced in 7acc619[1], but it wasn't triggered in my setup
until 18a2689[2] was merged to Linus' branch at point df0914[3]. IOW;
when PM is working as it was supposed to.
However, it seems most of the time this is used in a way that keeps the
counter above 0, so nobody noticed. Also, it seems to depend on the
configuration used in versions before 3.1, but not later (or in it).
I found the problem by loading isp1704_charger before any usb gadgets:
http://article.gmane.org/gmane.linux.kernel/1226122
All versions after 2.6.39 are affected.

On some failures, the country_code field of an acm structure is freed
without freeing the acm structure itself. Elsewhere, operations including
memcpy and kfree are performed on the country_code field. The patch sets
the country_code field to NULL when it is freed, and likewise sets the
country_code_size field to 0.

commit 1bb0b7d21584b3f878e2bc880db62351ddee5185 upstream.
When using a >8bpp framebuffer, offb advertises truecolor, not directcolor,
and doesn't touch the color map even if it has a corresponding access method
for the real hardware.
Thus it needs to set the pseudo-palette with all 3 components of the color,
like other truecolor framebuffers, not with copies of the color index like
a directcolor framebuffer would do.
This went unnoticed for a long time because it's pretty hard to get offb
to kick in with anything but 8bpp (old BootX under MacOS will do that and
qemu does it).

commit eea915bb0d1358755f151eaefb8208a2d5f3e10c upstream.
This oops was reported recently:
firmware_loading_store+0xf9/0x17b
dev_attr_store+0x20/0x22
sysfs_write_file+0x101/0x134
vfs_write+0xac/0xf3
sys_write+0x4a/0x6e
system_call_fastpath+0x16/0x1b
The complete backtrace was unfortunately not captured, but details can be found
here:
https://bugzilla.redhat.com/show_bug.cgi?id=769920
The cause is fairly clear.
Its caused by the fact that firmware_loading_store has a case 0 in its
switch statement that reads and writes the fw_priv->fw poniter without the
protection of the fw_lock mutex. since there is a window between the time that
_request_firmware sets fw_priv->fw to NULL and the time the corresponding sysfs
file is unregistered, its possible for a user space application to race in, and
write a zero to the loading file, causing a NULL dereference in
firmware_loading_store. Fix it by extending the protection of the fw_lock mutex
to cover all of the firware_loading_store function.

commit 157e8bf8b4823bfcdefa6c1548002374b61f61df upstream.
This reverts commit c0afabd3d553c521e003779c127143ffde55a16f.
It causes failures on Toshiba laptops - instead of disabling the alarm,
it actually seems to enable it on the affected laptops, resulting in
(for example) the laptop powering on automatically five minutes after
shutdown.
There's a patch for it that appears to work for at least some people,
but it's too late to play around with this, so revert for now and try
again in the next merge window.
