linux.git/drivers/usb/core, branch v2.6.14

Use the new "kill_proc_info_as_uid()" for USB disconnect too

2005-10-10T23:31:30+00:00

All the same issues - we can't just save the pointer to the thread, we
must save the pid/uid/euid combination.

[PATCH] Fix signal sending in usbdevio on async URB completion

2005-10-10T23:16:33+00:00

If a process issues an URB from userspace and (starts to) terminate
before the URB comes back, we run into the issue described above.  This
is because the urb saves a pointer to "current" when it is posted to the
device, but there's no guarantee that this pointer is still valid
afterwards.

In fact, there are three separate issues:

1) the pointer to "current" can become invalid, since the task could be
   completely gone when the URB completion comes back from the device.

2) Even if the saved task pointer is still pointing to a valid task_struct,
   task_struct->sighand could have gone meanwhile.

3) Even if the process is perfectly fine, permissions may have changed,
   and we can no longer send it a signal.

So what we do instead, is to save the PID and uid's of the process, and
introduce a new kill_proc_info_as_uid() function.

[PATCH] usb/core/hcd-pci.c: don't free_irq() on suspend

2005-09-30T16:23:30+00:00

the free_irq() in USB suspend breaks resume on some setups where USB
(ohci/ehci) shares the interrupt with an other device.

[PATCH] driver core: add helper device_is_registered()

2005-09-22T14:58:24+00:00

add the helper and use it instead of open coding the klist_node_attached() check
(which is a layering violation IMHO)

[PATCH] USB: relax usbcore reset timings

2005-09-12T19:23:49+00:00

This appears to help some folk, please merge.
This patch relaxes reset timings.  There are some reports that it
helps make enumeration work better on some high speed devices.

[PATCH] USB: get rid of minor log spamming

2005-09-12T19:23:43+00:00

Routine cases like handoff-to-companion shouldn't trigger diagnostics.
This gets rid of some recently added log spamming.  It's routine for
hub_port_wait_reset() to return -ENOTCONN to indicate handoff from
highspeed hubs to companions, so an error message is incorrect.

[PATCH] usbcore: small changes to HCD glue layer

2005-09-12T19:23:39+00:00

This patch (as549) introduces two small changes in the HCD glue layer.
The first simply removes a redundant test.  The second allows root-hub
polling to continue for a single iteration after a host controller dies;
this is needed for the patch that follows.

[PATCH] ehci: add think_time

2005-09-08T23:28:35+00:00

This adds think_time to the usb_tt struct and sets it appropriately
(measured in ns); this can help us implement better split transaction
scheduling.

[PATCH] USB: remove annoying message

2005-09-08T23:28:25+00:00

Avoid an annoying message that can appear if devices are disconnected
in the middle of a USB scatterlist operation.

Message noted in http://bugzilla.kernel.org/show_bug.cgi?id=4373
(but the real issue there seems to be a SCSI level hang).
