commit 108e02b12921078a59dcacd048079ece48a4a983 upstream.
Fix regression introduced by commit b1ffb4c851f1 ("USB: Fix Corruption
issue in USB ftdi driver ftdi_sio.c") which caused the termios settings
to no longer be initialised at open. Consequently it was no longer
possible to set the port to the default speed of 9600 baud without first
changing to another baud rate and back again.

Properly clamp temperature limits set by the user. Without this fix,
attempts to write temperature limits above the maximum supported by
the chip (255 degrees Celsius) would arbitrarily and unexpectedly
result in the limit being set to 0 degree Celsius.

The baud_base is device specific and can not be changed. This restores
the old (pre-2005) behaviour which was changed due to a

commit 0bfc96cb77224736dfa35c3c555d37b3646ef35e upstream.
[ Changes with respect to 3.3: return -ENOTTY from scsi_verify_blk_ioctl
and -ENOIOCTLCMD from sd_compat_ioctl. ]
Linux allows executing the SG_IO ioctl on a partition or LVM volume, and
will pass the command to the underlying block device. This is
well-known, but it is also a large security problem when (via Unix
permissions, ACLs, SELinux or a combination thereof) a program or user
needs to be granted access only to part of the disk.
This patch lets partitions forward a small set of harmless ioctls;
others are logged with printk so that we can see which ioctls are
actually sent. In my tests only CDROM_GET_CAPABILITY actually occurred.
Of course it was being sent to a (partition on a) hard disk, so it would
have failed with ENOTTY and the patch isn't changing anything in
practice. Still, I'm treating it specially to avoid spamming the logs.
In principle, this restriction should include programs running with
CAP_SYS_RAWIO. If for example I let a program access /dev/sda2 and
/dev/sdb, it still should not be able to read/write outside the
boundaries of /dev/sda2 independent of the capabilities. However, for
now programs with CAP_SYS_RAWIO will still be allowed to send the
ioctls. Their actions will still be logged.
This patch does not affect the non-libata IDE driver. That driver
however already tests for bd != bd->bd_contains before issuing some
ioctl; it could be restricted further to forbid these ioctls even for
programs running with CAP_SYS_ADMIN/CAP_SYS_RAWIO.

This reverts commit c8cdf3f97d34d906e0519d5cbc2ab3f81269d0b4, applied on
linux 2.6.32.53 stable release, as it can introduce the following build
error while building 2.6.32.y on armel:

linux-2.6.32/drivers/mmc/host/mmci.c:238: error: implicit declaration of function 'mmci_dma_data_error'
Aparently the commit was wrongly pushed into 2.6.32, since it depends on
commit c8ebae37 ("ARM: mmci: add dmaengine-based DMA support"), not
present on 2.6.32.

commit 598781d71119827b454fd75d46f84755bca6f0c6 upstream.
If the master tries to authenticate a client using drm_authmagic and
that client has already closed its drm file descriptor,
either wilfully or because it was terminated, the
call to drm_authmagic will dereference a stale pointer into kmalloc'ed memory
and corrupt it.
Typically this results in a hard system hang.
This patch fixes that problem by removing any authentication tokens
(struct drm_magic_entry) open for a file descriptor when that file
descriptor is closed.

commit 878b753e32ca765cd346a5d3038d630178ec78ff upstream.
[ changed s/usb_free_coherent/usb_buffer_free/ for 2.6.32.x]
In the WDM class driver a disconnect event leads to calls to
usb_free_coherent to put back two USB DMA buffers allocated earlier.
The call to usb_free_coherent uses a different size parameter
(desc->wMaxCommand) than the corresponding call to usb_alloc_coherent
(desc->bMaxPacketSize0).
When a disconnect event occurs, this leads to 'bad dma' complaints
from usb core because the USB DMA buffer is being pushed back to the
'buffer-2048' pool from which it has not been allocated.
This patch against the most recent linux-2.6 kernel ensures that the
parameters used by usb_alloc_coherent & usb_free_coherent calls in
cdc-wdm.c match.

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)

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 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.

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 6ac6519b93065625119a347be1cbcc1b89edb773 upstream.
After registering the task free notifier we possibly have tasks in our
dying_tasks list. Free them after unregistering the notifier in case
of an error.

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.

commit 03b147083a2f9a2a3fbbd2505fa88ffa3c6ab194 upstream.
Stanse found a potential NULL dereference in scsi_kill_request.
Instead of triggering BUG() in 'if (unlikely(cmd == NULL))' branch,
the kernel will Oops earlier on cmd dereference.
Move the dereferences after the if.
