commit a18a920c70d48a8e4a2b750d8a183b3c1a4be514 upstream.
This patch validates sdev pointer in scsi_dh_activate before proceeding further.
Without this check we might see the panic as below. I have seen this
panic multiple times..

commit 6c15d74defd38e7e7f8805392578b7a1d508097e upstream.
At this point if skb->len happens to be 2, the subsequant skb_pull(skb, 4)
call won't work and the skb->len won't be decreased and won't ever reach 0,
resulting in an infinite loop.
With an ASIX 88772 under heavy load, without this patch, rx_fixup() reaches
an infinite loop in less than a minute. With this patch applied,
no infinite loop even after hours of heavy load.

commit 694c6301e515bad574af74b6552134c4d9dcb334 upstream.
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.

the feature to fix an oops
commit 1a3a026ba1b6bbfe0b7f79ab38cf991d691e7c9a upstream.
Echo vendor and product number of a non usb-storage device to
usb-storage driver's new_id, then plug in the device to host and you
will find following oops msg, the root cause is usb_stor_probe1()
refers invalid id entry if giving a dynamic id, so just disable the
feature.

commit 59bf5cf94f0fa3b08fb1258b52649077b7d0914d upstream.
We were sending data on the stack when uploading firmware, which causes
some machines fits, and is not allowed. Fix this by using the buffer we
already had around for this very purpose.

commit e7c8e8605d0bafc705ff27f9da98a1668427cc0f upstream.
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 130c5ce716c9bfd1c2a2ec840a746eb7ff9ce1e6 upstream.
This fixes the A->B/B->A locking dependency, see the warning below.
The function task_exit_notify() is called with (task_exit_notifier)
.rwsem set and then calls sync_buffer() which locks buffer_mutex. In
sync_start() the buffer_mutex was set to prevent notifier functions to
be started before sync_start() is finished. But when registering the
notifier, (task_exit_notifier).rwsem is locked too, but now in
different order than in sync_buffer(). In theory this causes a locking
dependency, what does not occur in practice since task_exit_notify()
is always called after the notifier is registered which means the lock
is already released.
However, after checking the notifier functions it turned out the
buffer_mutex in sync_start() is unnecessary. This is because
sync_buffer() may be called from the notifiers even if sync_start()
did not finish yet, the buffers are already allocated but empty. No
need to protect this with the mutex.
So we fix this theoretical locking dependency by removing buffer_mutex
in sync_start(). This is similar to the implementation before commit:
750d857 oprofile: fix crash when accessing freed task structs
which introduced the locking dependency.

commit 745718132c3c7cac98a622b610e239dcd5217f71 upstream.
When we tear down a device we try to flush all outstanding
commands in scsi_free_queue(). However the check in
scsi_request_fn() is imperfect as it only signals that
we _might start_ aborting commands, not that we've actually
aborted some.
So move the printk inside the scsi_kill_request function,
this will also give us a hint about which commands are aborted.

Previously we claimed device ID 0x7450, regardless of the vendor, which is
clearly wrong. Now we'll claim that device ID only for AMD.
I suspect this was just a typo in the original code, but it's possible this
change will break shpchp on non-7450 AMD bridges. If so, we'll have to fix
them as we find them.

commit 2f640bf4c94324aeaa1b6385c10aab8c5ad1e1cf upstream.
The 8020i protocol (also 8070i and QIC-157) uses 12-byte commands;
shorter commands must be padded. Simon Detheridge reports that his
3-TB USB disk drive claims to use the 8020i protocol (which is
normally meant for ATAPI devices like CD drives), and because of its
large size, the disk drive requires the use of 16-byte commands.
However the usb_stor_pad12_command() routine in usb-storage always
sets the command length to 12, making the drive impossible to use.
Since the SFF-8020i specification allows for 16-byte commands in
future extensions, we may as well accept them. This patch (as1490)
changes usb_stor_pad12_command() to leave commands larger than 12
bytes alone rather than truncating them.

Fix for ftdi_set_termios() glitching output
ftdi_set_termios() is constantly setting the baud rate, data bits and parity
unnecessarily on every call, . When called while characters are being
transmitted can cause the FTDI chip to corrupt the serial port bit stream
output by stalling the output half a bit during the output of a character.
Simple fix by skipping this setting if the baud rate/data bits/parity are
unchanged.

commit 9bab0b7fbaceec47d32db51cd9e59c82fb071f5a upstream
This adds a mechanism to resume selected IRQs during syscore_resume
instead of dpm_resume_noirq.
Under Xen we need to resume IRQs associated with IPIs early enough
that the resched IPI is unmasked and we can therefore schedule
ourselves out of the stop_machine where the suspend/resume takes
place.
This issue was introduced by 676dc3cf5bc3 "xen: Use IRQF_FORCE_RESUME".
Back ported to 2.6.32 (which lacks syscore support) by calling the relavant
resume function directly from sysdev_resume).
