[PATCH] Three one-liners in md.c

The main problem fixes is that in certain situations stopping md arrays may
take longer than you expect, or may require multiple attempts.  This would
only happen when resync/recovery is happening.

This patch fixes three vaguely related bugs.

1/ The recent change to use kthreads got the setting of the
   process name wrong.  This fixes it.
2/ The recent change to use kthreads lost the ability for
   md threads to be signalled with SIG_KILL.  This restores that.
3/ There is a long standing bug in that if:
    - An array needs recovery (onto a hot-spare) and
    - The recovery is being blocked because some other array being
       recovered shares a physical device and
    - The recovery thread is killed with SIG_KILL
   Then the recovery will appear to have completed with no IO being
   done, which can cause data corruption.
   This patch makes sure that incomplete recovery will be treated as
   incomplete.

Note that any kernel affected by bug 2 will not suffer the problem of bug
3, as the signal can never be delivered.  Thus the current 2.6.14-rc
kernels are not susceptible to data corruption.  Note also that if arrays
are shutdown (with "mdadm -S" or "raidstop") then the problem doesn't
occur.  It only happens if a SIGKILL is independently delivered as done by
'init' when shutting down.

tracking a different process's CPU time clock when the process owning
the timer exits, we deadlock on tasklist_lock in posix_cpu_timer_del via

That code was using tasklist_lock to check for a race with __exit_signal
being called on the timer-target task and clearing its ->signal.
However, there is actually no such race.  __exit_signal will have called
posix_cpu_timers_exit and posix_cpu_timers_exit_group before it does
that.  Those will clear those k_itimer's association with the dying
task, so posix_cpu_timer_del will return early and never reach the code
in question.

In addition, posix_cpu_timer_del called from exit_itimers during execve
or directly from timer_delete in the process owning the timer can race
with an exiting timer-target task to cause a double put on timer-target

[PATCH] b44: alternate allocation option for DMA descriptors

This is a (final?) hack to support the odd DMA allocation requirements
of the b44 hardware.  The b44 hardware has a 30-bit DMA mask.  On x86,
anything less than a 32-bit DMA mask forces allocations into the 16MB
GFP_DMA range.  The memory there is somewhat limited, often resulting
in an inability to initialize the b44 driver.

This hack uses streaming DMA allocation APIs in order to provide an
alternative in case the GFP_DMA allocation fails.  It is somewhat ugly,
but not much worse than the similar existing hacks to support SKB
allocations in the same driver.  FWIW, I have received positive
feedback on this from several Fedora users.

[PATCH] via-rhine: change mdelay to msleep and remove from ISR path

Get rid of the mdelay call in rhine_disable_linkmon.  The function
is called from the via-rhine versions of mdio_read and mdio_write.
Those functions are indirectly called from rhine_check_media and
rhine_tx_timeout, both of which can be called in interrupt context.

So, create tx_timeout_task and check_media_task as instances of struct
work_struct inside of rhine_private.  Then, change rhine_tx_timeout to
invoke schedule_work for tx_timeout_task (i.e. rhine_tx_timeout_task),
moving the work to process context.  Also, change rhine_error (invoked
from rhine_interrupt) to invoke schedule_work for check_media_task
(i.e. rhine_check_media_task), which simply calls rhine_check media
in process context.  Finally, add a call to flush_scheduled_work in
rhine_close to avoid any resource conflicts with pending work items.

Clarify RCU implementation in bpqether.c.

Because bpq_new_device() calls list_add_rcu() and bpq_free_device() calls

list_for_each_entry() in bpq_get_ax25_dev() and in bpq_seq_start().

Add rcu dereference protection in bpq_seq_next().

The rcu_read_lock()/unlock() in bpq_device_event() are removed because
netdev event handlers are called with RTNL locking in place.

FYI: bpq_free_device() calls list_del_rcu() which, per list.h, requires
synchronize_rcu() which can block or call_rcu() or call_rcu_bh() which
cannot block.  Herbert Xu notes that synchronization is done here by

4. In register test, expected value from rx_queue_cfg register
is made to depend on adapter type.
5. After the test, need to restore values at EEPROM offsets

19 years ago[PATCH] USB: fix bug in handling of highspeed usb HID devices
Christian Krause [Mon, 17 Oct 2005 21:30:48 +0000 (14:30 -0700)]
[PATCH] USB: fix bug in handling of highspeed usb HID devices

During the development of an USB device I found a bug in the handling of
Highspeed HID devices in the kernel.

What happened?

Highspeed HID devices are correctly recognized and enumerated by the
kernel. But even if usbhid kernel module is loaded, no HID reports are
received by the kernel.

The output of the hardware USB analyzer told me that the host doesn't
even poll for interrupt IN transfers (even the "interrupt in" USB
transfer are polled by the host).

After some debugging in hid-core.c I've found the reason.

In case of a highspeed device, the endpoint interval is re-calculated in
driver/usb/input/hid-core.c:

line 1669:
             /* handle potential highspeed HID correctly */
             interval = endpoint->bInterval;
             if (dev->speed == USB_SPEED_HIGH)
                   interval = 1 << (interval - 1);

Basically this calculation is correct (refer to USB 2.0 spec, 9.6.6).
This new calculated value of "interval" is used as input for
usb_fill_int_urb:

line 1685:

            usb_fill_int_urb(hid->urbin, dev, pipe, hid->inbuf, 0,
                   hid_irq_in, hid, interval);

Unfortunately the same calculation as above is done a second time in
usb_fill_int_urb in the file include/linux/usb.h:

line 933:
        if (dev->speed == USB_SPEED_HIGH)
                urb->interval = 1 << (interval - 1);
        else
                urb->interval = interval;

This means, that if the endpoint descriptor (of a high speed device)
specifies e.g. bInterval = 7, the urb->interval gets the value:

hid-core.c: interval = 1 << (7-1) = 0x40 = 64
urb->interval = 1 << (interval -1) = 1 << (63) = integer overflow

Because of this the value of urb->interval is sometimes negative and is
rejected in core/urb.c:
line 353:
                /* too small? */
                if (urb->interval <= 0)
                        return -EINVAL;

The conclusion is, that the recalculaton of the interval (which is
necessary for highspeed) should not be made twice, because this is
simply wrong. ;-)

Re-calculation in usb_fill_int_urb makes more sense, because it is the
most general approach. So it would make sense to remove it from
hid-core.c.

Because in hid-core.c the interval variable is only used for calling
usb_fill_int_urb, it is no problem to remove the highspeed
re-calculation in this file.

[PATCH] SVGATextMode fix

Fix bug 5441.

I didn't know about messy programs like svgatextmode...  Couldn't this be
integrated in some linux/drivers/video/console/svgacon.c ?...  So because
of the existence of the svgatextmode program, the kernel is not supposed to
touch to CRT_OVERFLOW/SYNC_END/DISP/DISP_END/OFFSET ?

Disabling the check in vgacon_resize() might help indeed, but I'm really
not sure whether it will work for any chipset: in my patch, CRT registers
are set at each console switch, since stty rows/cols apply to consoles
separately...

The attached solution is to keep the test, but if it fails, we assume that
the caller knows what it does (i.e.  it is svgatextmode) and then disable
any further call to vgacon_doresize.  Svgatextmode is usually used to
_expand_ the display, not to shrink it.  And it is harmless in the case of
a too big stty rows/cols: the display will just be cropped.  I tested it on
my laptop, and it works fine with svgatextmode.

A better solution would be that svgatextmode explicitely tells the kernel
not to care about video timing, but for this an interface needs be defined
and svgatextmode be patched.

It seems that all the list_*_rcu primitives are missing a memory barrier

#define list_for_each_rcu(pos, head) \
for (pos = (head)->next; prefetch(pos->next), pos != (head); \
pos = rcu_dereference(pos->next))

It will go something like:

pos = (head)->next

prefetch(pos->next)

pos != (head)

do stuff

We're missing a barrier here.

pos = rcu_dereference(pos->next)

fetch pos->next

barrier given by rcu_dereference(pos->next)

store pos

Without the missing barrier, the pos->next value may turn out to be stale.
In fact, if "do stuff" were also dereferencing pos and relying on
list_for_each_rcu to provide the barrier then it may also break.

serial converter driver (usbserial.o, drivers/usb/serial/generic.c).
The bug manifests, as far as I can tell, whenever you attempt to write
to the device -- the write will never complete (write() returns 0, or
blocks).
