vmxnet3 has a 16Kbytes limit per tx descriptor, that happened to work
as long as we provided PAGE_SIZE fragments.

Our stack can now build larger fragments, so we need to split them to
the 16kbytes boundary.

The sleeping code in iscsi_target_tx_thread() is susceptible to the classic
missed wakeup race:

 - TX thread finishes handle_immediate_queue() and handle_response_queue(),
   thinks both queues are empty.
 - Another thread adds a queue entry and does wake_up_process(), which does
   nothing because the TX thread is still awake.
 - TX thread does schedule_timeout() and sleeps forever.

In practice this can kill an iSCSI connection if for example an initiator
does single-threaded writes and the target misses the wakeup window when
queueing an R2T; in this case the connection will be stuck until the
initiator loses patience and does some task management operation (or kills
the connection entirely).

Fix this by converting to wait_event_interruptible(), which does not
suffer from this sort of race.

The expression (max_sectors * block_size) might overflow a u32
(indeed, since iblock sets max_hw_sectors to UINT_MAX, it is
guaranteed to overflow and end up with a much-too-small result in many

doesn't require multiplication.

Microsoft Digital Media Keyboard 3000 has two interfaces, and the
second one has a report descriptor with a bug. The second collection
says:
05 01 -- global; usage page -- 01 -- Generic Desktop Controls
09 80 -- local; usage -- 80 -- System Control
a1 01 -- main; collection -- 01 -- application

85 03 -- global; report ID -- 03
19 00 -- local; Usage Minimum -- 00
29 ff -- local; Usage Maximum -- ff
15 00 -- global; Logical Minimum -- 0
26 ff 00 -- global; Logical Maximum -- ff
81 00 -- main; input

c0 -- main; End Collection

I.e. it makes us think that there are all kinds of usages of system
control. That the keyboard is a not only a keyboard, but also a
joystick, mouse, gamepad, keypad, etc. The same as for the Wireless
Desktop Receiver, this should be Physical Min/Max. So fix that
appropriately.

sending all touch events with a pressure of 0. Removing the announcement
will make tslib fall back to emulating the pressure on touch events so

Commit 2863b9eb didn't take into account the changes to add TRIM support to
RAID10 (commit 532a2a3f).  That is, when using dm-raid.c to create the
RAID10 arrays, there is no mddev->gendisk or mddev->queue.  The code added
to support TRIM simply assumes that mddev->queue is available without
checking.  The result is an oops any time dm-raid.c attempts to create a
RAID10 device.

setup_conf in raid1.c uses conf->raid_disks before assigning
a value.  It is used when including 'Replacement' devices.

The consequence is that assembling an array which contains a
replacement will misbehave and either not include the replacement, or
not include the device being replaced.

Though this doesn't lead directly to data corruption, it could lead to
reduced data safety.

So use mddev->raid_disks, which is initialised, instead.

Bug was introduced by commit c19d5798

Due to the SMP nature of some of the chips, which have per CPU
registers, the driver does not use the generic irq_gc_mask_set_bit() &
irq_gc_mask_clr_bit() functions, which only support a single register.
The driver has its own implementation of these functions, which can
pick the correct register depending on the CPU being used. The
functions do however use the gc->mask_cache value.

The call to irq_setup_generic_chip() was passing
IRQ_GC_INIT_MASK_CACHE, which caused the gc->mask_cache to be
initialized to the contents of some random register. This resulted in
unexpected interrupts been delivered from random GPIO lines.

The ath9k xmit functions for AMPDUs can send frames as non-aggregate in case
only one frame is currently available. The client will then answer using a
normal Ack instead of a BlockAck. This acknowledgement has no TID stored and
therefore the hardware is not able to provide us the corresponding TID.

The TID set by the hardware in the tx status descriptor has to be seen as
undefined and not as a valid TID value for normal acknowledgements. Doing
otherwise results in a massive amount of retransmissions and stalls of
connections.

Users may experience low bandwidth and complete connection stalls in
environments with transfers using multiple TIDs.

This regression was introduced in b11b160d
