I'm having problem with oopses when rebooting, if I modprobe g_serial
and rmmod g_serial and do a reboot I get an oops in device_shutdown().
The reason seems to be that usb_gadget_unregister_driver() doesn't do
enough cleanup. With this at91_udc patch I don't get the oops.

Claim the interface for a USB to serial converter when the tty is open,
and release the interface when the tty is closed.
If a driver doesn't provide a resume function, use the generic resume
instead.
Make sure the generic resume function does not submit the URBs if we're
coming back from autosuspend. On autoresume, we know that the open
function will be called next, which will attempt to submit the URBs. If
we submit them in the resume function, the open will fail.
This works for:
- autosuspend
- suspending with the tty open or closed
- hibernate with the tty closed
A hibernate (or a suspend that causes the USB subsystem to lose power)
has issues. If you have the tty open when you hibernate, a new tty will
be created when the device re-enumerates during resume.

The usb serial method set_termios() is called for the first time from
open() method in order to set up the termios structure with the default
device's settings, ignoring the current settings. Once it's initialized,
the next set_termios() calls will update the device with the
tty->termios settings.
Currently USB serial console code calls the driver open() method without
a tty and after that will allocate a fake tty and termios so the command
line arguments can be applied to the device
(console=ttyUSB0,115200,...). This makes the driver overwrite the
termios with the default settings and not applying the command line
options.
This patch changes usb_console_setup() to allocate the fake tty and
termios before the open() method is called.

When a usb serial adapter is used as console, the usb serial console
driver bumps the open_count on the port struct used but doesn't attach
a real tty to it (only a fake one temporaly). If this port is opened later
using the regular character device interface, the open method won't
initialize the port, which is the expected, and will receive a brand new
tty struct created by tty layer, which will be stored in port->tty.
When the last close is issued, open_count won't be 0 because of the
console usage and the port->tty will still contain the old tty value. This
is the last ttyUSB<n> close so the allocated tty will be freed by the
tty layer. The usb_serial and usb_serial_port are still in use by the
console, so port_free() won't be called (serial_close() ->
usb_serial_put() -> destroy_serial() -> port_free()), so the scheduled
work (port->work, usb_serial_port_work()) will still run. And
usb_serial_port_work() does:
(...)
tty = port->tty;
if (!tty)
return;
tty_wakeup(tty);
which causes (manually copied):

needs to be re-enabled every time you get a new kernel. Additionally a

Currently our users have to follow the instructions we provide at

is too complicated to compile their own kernel module.
We are aware that you can specify one additional device using the

This patch relaxes the default SCSI DMA alignment from 512 bytes to 4
bytes. I remember from previous discussions that usb and firewire have
sector size alignment requirements, so I upped their alignments in the
respective slave allocs.
The reason for doing this is so that we don't get such a huge amount of

- isd200_action() was still using direct liniar pointers in issuing
commands to the USB transport level. This is no longer supported,
use one-element scatterlist instead.
- Adjustment of command's length in the case of scsi-to-ata translation
is now restored before return to queuecommand, since other wise it can
leak BIOs.
- isd200_action() return Error on unknown requests. Used to print an error
but still try to send garbage cdb.

Cleaning out all the incorrect 'no change made' checks for termios

lose sync and bits if you tell it to make no changes. This shows up with

To fix this the driver check for meaningful hardware changes is restored

The OHCI IRQ handler has an optimisation that avoids reading some
chip registers when the controller reports that the interrupt was
triggered *only* because completed requests were written into the
controller's "done list" and handed to the host.
This mechanism can't be used on some controllers. Among others, it
fails for the SA1111 and the AMCC 440EP PowerPC processor.
This patch removes the optimisation and makes the code clearer.

Correct hanging while disconnecting the USB device cable. Prevent a race

A usb resume interrupt was firing after the vbus interrupt : the IP was
then already stoped and not able to deal with it (no more clock). A simple
interrupt disabling is ok as the "end of bus reset" irq is non maskable and
ok to resume the USB device IP.

This patch (as1010) was written by both Kay Sievers and me. It solves
the problem of duplicated keys in USB uevent structures by refactoring
the uevent subroutines, taking advantage of the way the hotplug core
calls uevent handlers for the device's bus and for the device's type.
Keys needed for both USB-device and USB-interface events are added in
usb_uevent(), which is the bus handler. Keys appropriate only for
USB-device or USB-interface events are added in usb_dev_uevent() or
usb_if_uevent() respectively, the type handlers.
In addition, unnecessary tests for NULL pointers are removed as are
duplicated debugging log statements.

usb_set_configuration() registers the interfaces and their files in
sysfs, it doesn't expect those files to exist already. But when an
interface is registered, its driver may call usb_set_interface() and
thereby cause the sysfs files to be created. The result is an error
when usb_set_configuration() goes on to create those same files again.
The (not-so-great) solution is to have usb_set_configuration() remove

converted many files to use the scatter gather helpers without ensuring
that the necessary headerfile <linux/scatterlist> is included. This
happened to work for ia64, powerpc, sparc64 and x86 because they
happened to drag in that file via their <asm/dma-mapping.h>.
On most of the others this probably broke.
Instead of increasing the header file spider web I choose to include

The task_struct->pid member is going to be deprecated, so start
using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in

The first thing to start with is the pid, printed to dmesg - in
this case we may safely use task_pid_nr(). Besides, printks produce
more (much more) than a half of all the explicit pid usage.

Various console drivers are able to resize the screen via the con_resize()
hook. This hook is also visible in userspace via the TIOCWINSZ, VT_RESIZE and
VT_RESIZEX ioctl's. One particular utility, SVGATextMode, expects that
con_resize() of the VGA console will always return success even if the
resulting screen is not compatible with the hardware. However, this
particular behavior of the VGA console, as reported in Kernel Bugzilla Bug
7513, can cause undefined behavior if the user starts with a console size
larger than 80x25.
To work around this problem, add an extra parameter to con_resize(). This
parameter is ignored by drivers except for vgacon. If this parameter is
non-zero, then the resize request came from a VT_RESIZE or VT_RESIZEX ioctl
and vgacon will always return success. If this parameter is zero, vgacon will
return -EINVAL if the requested size is not compatible with the hardware. The
latter is the more correct behavior.
With this change, SVGATextMode should still work correctly while in-kernel and
stty resize calls can expect correct behavior from vgacon.

This patch (as1002) fixes a small race which can occur when a driver
expects usbcore to reschedule an autosuspend request. If the request
arrives too late, it won't be rescheduled. The patch adds an extra
argument to autosuspend_check(), indicating that a reschedule is
needed no matter how much time has elapsed.
It also tries to avoid letting asynchronous changes to the value of
jiffies cause a delay to become negative, by caching a local copy of
the current time.

At the company where I work we need such support, and one of my
co-workers, Jane Liu, pointed out that SCSI low-layer drivers need to
specify what size CDBs they accept. After looking through the code it
became obvious that the current USB Storage code accepted the default of
12-byte CDBs, so I changed it to accept 16-byte CDBs. This allows our
device to work.

big-endian OHCI must shift 16 bits ... unless the spec is not followed.

Fix a longstanding race in the Ethernet gadget driver, which can cause an
oops on device disconnect. The fix is just to make the TX path check
whether its freelist is empty. That check is otherwise not necessary,
since the queue is always stopped when that list empties (and restarted
when request completion puts an entry back on that freelist).
The race window starts when the network code decides to transmit a packet,
and ends when hard_start_xmit() grabs the freelist lock. When disconnect()
is called inside that window, it shuts down the TX queue and breaks the
otherwise-solid assumption that packets are never sent through a TX queue
that's stopped.

This patch (as995) cleans up the remains of the former NO_AUTOSUSPEND
quirk. Since autosuspend is disabled by default, we will let
userspace worry about which devices can safely be suspended. Thus the
lengthy series of quirk entries is no longer needed, and neither is
the quirk ID. I suppose someone might eventually run across a hub
that can't be suspended; let's ignore the possibility for now.
The patch also cleans up the hasty way in which autosuspend gets
disabled. Setting udev->autosuspend_delay to -1 wasn't quite right,
because the value is always supposed to be a multiple of HZ. It's
better to leave the delay value alone and set autosuspend_disabled,
which is what the quirk routine used to do.

Serial core would do a kfree() on memory already freed.

Currently, every driver under drivers/usb/misc/ also has to be listed in
drivers/usb/Makefile. This has been forgotten more than once, and this
patch changes drivers/usb/Makefile to simply always visit
drivers/usb/misc/ when building the USB code.

This weekend I was hacking around with a trivial USB driver for talking
to the boot load firmware of a USB Bit Whacker. It's running the
MicroChip Pic18 boot loader firmware and I'm putting together a flash
program for writing new FW to the thing.
Anyway in my use of the usb-skeleton.c as my starting point I discovered
my test program was getting hung up after attempting to write a buffer.
The application and driver where hung in a way that required me to
reboot to get it to clean up so I could try again.
It turned out the code path through skel_open can grap the driver's
io_mutex lock and forget to release it.
The following patch fixes the problem for me.

This patch (as989) makes usbcore flush all outstanding URBs for each
device as the device is suspended. This will be true even when
CONFIG_USB_SUSPEND is not enabled.
In addition, an extra can_submit flag is added to the usb_device
structure. That flag will be turned off whenever a suspend request
has been received for the device, even if the device isn't actually
suspended because CONFIG_USB_SUSPEND isn't set.
It's no longer necessary to check for the device state being equal to
USB_STATE_SUSPENDED during URB submission; that check can be replaced
by a check of the can_submit flag. This also permits us to remove
some questionable references to the deprecated power.power_state field.
