The generic usbserial driver in Linux 2.6.31 halts its receiving
channel in response to throttle requests from the line discipline.
Unfortunately it drops the contents of the first URB received after
throttling takes effect. This patch corrects that problem.

This patch (as1293) fixes a problem with the ipaq serial driver. It
tries to bind to all the interfaces, even those that don't have enough
endpoints. The symptom is an invalid memory reference and oops when
the device is plugged in.

When the host controller dies or is removed while a device is plugged in,
the USB core will attempt to deallocate the struct usb_device. That will
call into xhci_free_dev(). This function used to attempt to submit a
disable slot command to the host controller and clean up the device
structures when that command returned. Change xhci_free_dev() to skip the
command submission and just free the memory if the host controller died.

When the host controller dies (e.g. it is removed from a PCI card slot),
the xHCI driver cannot expect commands to complete. The buggy code this
patch fixes would mark an URB as canceled and then expect the URB to be
completed when the stop endpoint command completed. That would never
happen if the host controller was dead, so the USB core would just hang in
the disconnect code.
If the host controller died, and the driver asks to cancel an URB, free
any structures associated with that URB and immediately give it back.

This patch (as1295) fixes a recently-added bug in the USB serial core.
If certain kinds of errors occur during probing, the core may call a
serial driver's release method without previously calling the attach
method. This causes some drivers (io_ti in particular) to perform an
invalid memory access.
The patch adds a new flag to keep track of whether or not attach has
been called.

- Re-structure read processing.
- Kill obsolete work queue and always push to tty in completion handler.
- Use tty_insert_flip_string instead of per character push when
possible.
- Fix stalled-read regression in 2.6.31 by using urb status to
determine when port is closed rather than port count.
- Fix race with open/close by checking ASYNCB_INITIALIZED in
unthrottle.
- Kill private rx_flag and lock and use throttle flags in

Remove superfluous error checks in completion handler:
- No need to check private data and urb pointers as we check urb-status
before dereferencing priv (which is not freed until urb has been killed
on close).
- No need to check tty as it is checked again when processing.
- No need to check urb->number_of_packets on bulk urb.
Note that both private data and tty are checked again before processing
(possibly from work queue which also is cancelled on close).

1. The memory into which we copy 'u1@u2' needs space for u1, @,
u2, and a final \0 which strcat copies in.
2. Strsep changes the value of its first argument. So use a
temporary variable to pass to it, so we pass the original
value to kfree!
3. Allocate an extra char to user_buf, because we need a trailing \0
since we later kstrdup it.
I am about to send out an LTP testcase for this driver, but
in addition the correctness of the hashing can be verified as
follows:
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
int main(int argc, char *argv[])
{
char in[41], out[20];
unsigned int v;
int i, ret;
ret = read(STDIN_FILENO, in, 40);
if (ret != 40)
exit(1);
in[40] = '\0';
for (i = 0; i < 20; i++) {
sscanf(&in[2*i], "%02x", &v);
out[i] = v;
}
write(STDOUT_FILENO, out, 20);
}
as root, to test userid 501 switching to uid 0, choosing
'random' string 'ab':
echo -n "501@0" > plain
openssl sha1 -hmac 'ab' plain |awk '{ print $2 '} > dgst
./unhex < dgst > dgst.u
mknod /dev/caphash 504 0
mknod /dev/capuse 504 1
chmod ugo+w /dev/capuse
cat dgst.u > /dev/caphash

echo "501@0@ab" > /dev/capuse
id -u # should now show 0.

A race shouldn't happen since all workqueues or handlers are canceled
or flushed before the event buffer is freed. A warning is triggered
now if the buffer is freed too early.
Also, this patch adds some comments about event buffer protection,
reworks some code and adds code to clear buffer_pos during alloc and
free of the event buffer.

The following patch checks the state of the EC and enable it if needed;
under Linux, native drivers are locked out from ACPI owned resources so
there's no risk of conflict.
