13 years agoxhci: Fix bug in control transfer cancellation.
Sarah Sharp [Fri, 6 May 2011 02:08:09 +0000 (19:08 -0700)]
xhci: Fix bug in control transfer cancellation.

When the xHCI driver attempts to cancel a transfer, it issues a Stop
Endpoint command and waits for the host controller to indicate which TRB
it was in the middle of processing.  The host will put an event TRB with
completion code COMP_STOP on the event ring if it stops on a control
transfer TRB (or other types of transfer TRBs).  The ring handling code
is supposed to set ep->stopped_trb to the TRB that the host stopped on
when this happens.

Unfortunately, there is a long-standing bug in the control transfer
completion code.  It doesn't actually check to see if COMP_STOP is set
before attempting to process the transfer based on which part of the
control TD completed.  So when we get an event on the data phase of the
control TRB with COMP_STOP set, it thinks it's a normal completion of
the transfer and doesn't set ep->stopped_td or ep->stopped_trb.

When the ring handling code goes on to process the completion of the Stop
Endpoint command, it sees that ep->stopped_trb is not a part of the TD
it's trying to cancel.  It thinks the hardware has its enqueue pointer
somewhere further up in the ring, and thinks it's safe to turn the control
TRBs into no-op TRBs.  Since the hardware was in the middle of the control
TRBs to be cancelled, the proper software behavior is to issue a Set TR
dequeue pointer command.

It turns out that the NEC host controllers can handle active TRBs being
set to no-op TRBs after a stop endpoint command, but other host
controllers have issues with this out-of-spec software behavior.  Fix this
behavior.

This patch should be backported to kernels as far back as 2.6.31, but it
may be a bit challenging, since process_ctrl_td() was introduced in some
refactoring done in 2.6.36, and some endian-safe patches added in 2.6.40
that touch the same lines.

usb: gadget: composite: Allow function drivers to pause control transfers

Some USB function drivers (e.g. f_mass_storage.c) need to delay or defer the
data/status stages of standard control requests like SET_CONFIGURATION or
SET_INTERFACE till they are done with their bookkeeping and are actually ready
for accepting new commands to their interface.

They can now achieve this functionality by returning USB_GADGET_DELAYED_STATUS
in their setup handlers (e.g. set_alt()). The composite framework will then
defer completion of the control transfer by not completing the data/status stages.

This ensures that the host does not send new packets to the interface till the
function driver is ready to take them.

When the function driver that requested for USB_GADGET_DELAYED_STATUS is done
with its bookkeeping, it should signal the composite framework to continue with
the data/status stages of the control transfer. It can do so by invoking
the new API usb_composite_setup_continue(). This is where the control transfer's
data/status stages are completed and host can initiate new transfers.

The DELAYED_STATUS mechanism is currently only supported if the expected data phase
is 0 bytes (i.e. w_length == 0). Since SET_CONFIGURATION and SET_INTERFACE are the
only cases that will use this mechanism, this is not a limitation.

xHCI 1.0: Block Interrupts for Isoch transfer

Currently an isoc URB is divided into multiple TDs, and every TD will
trigger an interrupt when it's processed. However, software can schedule
multiple TDs at a time, and it only needs an interrupt every URB.

xHCI 1.0 introduces the Block Event Interrupt(BEI) flag which allows Normal
and Isoch Transfer TRBs to place an Event TRB on an Event Ring but not
assert an intrrupt to the host, and the interrupt rate is significantly
reduced and the system performance is improved.

VM: skip the stack guard page lookup in get_user_pages only for mlock

The logic in __get_user_pages() used to skip the stack guard page lookup
whenever the caller wasn't interested in seeing what the actual page
was.  But Michel Lespinasse points out that there are cases where we
don't care about the physical page itself (so 'pages' may be NULL), but
do want to make sure a page is mapped into the virtual address space.

So using the existence of the "pages" array as an indication of whether
to look up the guard page or not isn't actually so great, and we really
should just use the FOLL_MLOCK bit.  But because that bit was only set
for the VM_LOCKED case (and not all vma's necessarily have it, even for
mlock()), we couldn't do that originally.

Fix that by moving the VM_LOCKED check deeper into the call-chain, which
actually simplifies many things.  Now mlock() gets simpler, and we can
also check for FOLL_MLOCK in __get_user_pages() and the code ends up
much more straightforward.

13 years agoslub: Fix the lockless code on 32-bit platforms with no 64-bit cmpxchg
Thomas Gleixner [Wed, 4 May 2011 13:38:19 +0000 (15:38 +0200)]
slub: Fix the lockless code on 32-bit platforms with no 64-bit cmpxchg

The SLUB allocator use of the cmpxchg_double logic was wrong: it
actually needs the irq-safe one.

That happens automatically when we use the native unlocked 'cmpxchg8b'
instruction, but when compiling the kernel for older x86 CPUs that do
not support that instruction, we fall back to the generic emulation
code.

And if you don't specify that you want the irq-safe version, the generic
code ends up just open-coding the cmpxchg8b equivalent without any
protection against interrupts or preemption.  Which definitely doesn't
work for SLUB.

This was reported by Werner Landgraf <w.landgraf@ru.ru>, who saw
instability with his distro-kernel that was compiled to support pretty
much everything under the sun.  Most big Linux distributions tend to
compile for PPro and later, and would never have noticed this problem.

This also fixes the prototypes for the irqsafe cmpxchg_double functions
to use 'bool' like they should.

[ Btw, that whole "generic code defaults to no protection" design just
  sounds stupid - if the code needs no protection, there is no reason to
  use "cmpxchg_double" to begin with.  So we should probably just remove
  the unprotected version entirely as pointless.   - Linus ]
