use non-existent CONFIG variables.  It complained of two uses in
ia64 specific code: CONFIG_IA64_SDV and CONFIG_KDB (both used in

[IA64] ar.itc access must really be after xtime_lock.sequence has been read

The ".acq" semantics of the load only apply w.r.t. other data access.
Reading the clock (ar.itc) isn't a data access so strange things can
happen here.  Specifically the read of ar.itc can be launched as soon
as the read of xtime_lock.sequence is ISSUED.  Since this may cache
miss, and that might cause a thread switch, and there may be cache
contention for the line containing xtime_lock, it may be a long time
before the actual value is returned, so the ar.itc value may be very
stale.

Move the consumption of r28 up before the read of ar.itc to make sure
that we really have got the current value of xtime_lock.sequence
before look at ar.itc.

13 years ago[IA64] use machvec=dig on hpzx1 platforms
Terry Loftin [Thu, 12 Jul 2007 23:23:22 +0000]
[IA64] use machvec=dig on hpzx1 platforms

On HP zx1 machines, the 'machvec=dig' parameter is needed for the
kdump kernel to avoid problems with the HP sba iommu.  The problem
is that during the boot of the kdump kernel, the iommu is re-initialized,
so in-flight DMA from improperly shutdown drivers causes an IOTLB
miss which leads to an MCA.  With kdump, the idea is to get into the
kdump kernel with as little code as we can, so shutting down drivers
properly is not an option.

The workaround is to add 'machvec=dig' to the kdump kernel boot
parameters.  This makes the kdump kernel avoid using the sba iommu
altogether, leaving the IOTLB intact.  Any ongoing DMA falls
harmlessly outside the kdump kernel.  After the kdump kernel reboots,
all devices will have been shutdown properly and DMA stopped.

This patch pushes that functionality into the sba iommu
initialization code, so that users won't have to find the obscure
documentation telling them about 'machvec=dig'.

This patch only affects HP platforms.  It still includes one
extern declaration in the file, because no applicable header file
exists.

usb gadget stack: remove usb_ep_*_buffer(), part 2

This patch removes controller driver infrastructure which supported
the now-removed usb_ep_{alloc,free}_buffer() calls.

As can be seen, many of the implementations of this were broken to
various degrees.  Many didn't properly return dma-coherent mappings;
those which did so were necessarily ugly because of bogosity in the
underlying dma_free_coherent() calls ... which on many platforms
can't be called from the same contexts (notably in_irq) from which
their dma_alloc_coherent() sibling can be called.

The main potential downside of removing this is that gadget drivers
wouldn't have specific knowledge that the controller drivers have:
endpoints that aren't dma-capable don't need any dma mappings at all.

usb gadget stack: remove usb_ep_*_buffer(), part 1

Remove usb_ep_{alloc,free}_buffer() calls, for small dma-coherent buffers.
This patch just removes the interface and its users; later patches will
remove controller driver support.

  - This interface is invariably not implemented correctly in the
    controller drivers (e.g. using dma pools, a mechanism which
    post-dates the interface by several years).

  - At this point no gadget driver really *needs* to use it.  In
    current kernels, any driver that needs such a mechanism could
    allocate a dma pool themselves.

Removing this interface is thus a simplification and improvement.

Note that the gmidi.c driver had a bug in this area; fixed.

code was never fully tested.  And it was never coded for OUT transfers
(which is where DMA would really help) ... because of chip errata on

botches (nothing automated data toggle).  So it's effectively been

USB: usb/dma doc updates

This patch updates some of the documentation about DMA buffer management
for USB, and ways to avoid extra copying.  Our understanding of the issues
has improved over time.

 - Most drivers should *avoid* the dma-coherent allocators.  There are
   a few exceptions (like the HID driver).

 - Some methods are currently commented out; it seems folk writing
   USB drivers aren't doing performance tuning at that level yet.

 - Just avoid highmem; there's no good way to pass an "I can do highmem
   DMA" capability through a driver stack.  This is easy, everything
   already avoids highmem.  But it'd be nice if x86_32 systems with much
   physical memory could use it directly with network adapters and mass
   storage devices.  (Patch, anyone?)

USB: usblp: add dynamic URBs, fix races

This patch's main bulk aims to make usblp the premier driver for code
pillaging once again. The code is as streamlined as possible and is bug-free
as possible. The usb-skeleton performs the same function, but is somewhat
abstract. The usblp is usb-skeleton which is actually used by many.

Since I combed a few small bugs away, this also fixes the small races we
had in usblp for a while. For example, now it's possible for several threads
to make write(2) calls (sounds silly, but consider a printer for paper
record, where every line of text is self-contained and thus it's all right
to have them interleaved). Also gone are issues with interrupts using
barriers dangerously.

This patch makes use of Oliver's anchor, and so it must trail the anchor
patch on the way to Linus.

13 years agousb: free DMA mappings if enqueue fails
Pete Zaitcev [Fri, 8 Jun 2007 20:37:49 +0000]
usb: free DMA mappings if enqueue fails

This patch releases DMA resources if enqueue fails in the HCD.

Linux had this bug ever since we converted from virt_to_bus for 2.4.
It is difficult to hit. A user would need a significant memory pressure
or some other unusual condition.

It was reported to me by IBM. They ran a management application for
RSA II adapters which sent Bulk requests to an Interrupt endpoint.
Submissions got rejected by HCD due to an invalid interval value
and the swiotlb pool became depleted in the matter of hours.

We fixed the invalid interval issue in devio.c separately, but this
seems to be a bug worth fixing as well.

13 years agosynchronization in usb_serial_put
Benny Halevy [Tue, 15 May 2007 08:15:27 +0000]
synchronization in usb_serial_put

I think there is a race between usb_serial_put() and
usb_serial_get_by_index() (and get_free_serial()) with regards
to handling the serial port refcount.

usb_serial_get_by_index() gets a reference on the serial port under
table_lock while return_serial releases all the returned ports
from the table under the same lock.  However, the table_lock is not
taken around the call to kref_put, theoretically allowing to sneak
in and grab a reference after kref_put has already determined that
the reference count is zero (and before calling destroy_serial)
causing use after free.

According to the USB Specification Revision 2.0 chapter 11.12.5
a hub experiencing an over-current condition must place all
affected ports in the powered-off state. It seems that some root
hubs need port power to be cycled by software in order to get back
to normal functionality after an over-current condition ... like
the EHCI implementation on an MPC8343E.

This patch (as923) makes usb-storage's control thread use
kthread_should_stop()/kthread_stop().  The scanning thread can't be
similarly converted until the core kthread implementation allows

The advantage of this change is that we can now be certain the control

Okay, from this it looks like there's a problem in the option.c serial
driver.  Glancing at the code, it's obvious why: The thing totally
abuses the USB API.
