USB serial likes to use port->tty back pointers for the real work it does and
to do so without any actual locking. Unfortunately when you consider hangup
events, hangup/parallel reopen or even worse hangup followed by parallel close
events the tty->port and port->tty pointers are not guaranteed to be the same
as port->tty is the active tty while tty->port is the port the tty may or
may not still be attached to.
So rework the entire API to pass the tty struct. For console cases we need
to pass both for now. This shows up multiple drivers that immediately crash
with USB console some of which have been fixed in the process.
Longer term we need a proper tty as console abstraction

USB debug port only supports 8 byte rx/tx packets. Although spec implies that
"if a packet larger than eight bytes is received from the remote computer, the
device must break the larger packet into eight-byte packets before sending the
data to the Debug Port", the real PLX NET20DC device does not handle it right -
data is corrupted on debug port end if serial interface sends >8 byte urbs.
Patch below fixes the issue by limiting tx urb to 8 byte.

The get/set 2101_config helpers take an unsigned int rather than an
int. It is safe to change these in each case and may even produce
better code as it will be an unsigned divide rather than a signed
divide in places. All other manipulation was setting/masking bits
which will not be affected by the sign change.

The cypress app note for the M8 states that for the USB low speed
version of the part, throughput is effectively limited to 800
bytes/sec. So if we were to try a faster baud rate in such cases then
we risk overrun errors on receive. Best to just identify this case
and limit the rate to 4800 baud or less (by ignoring any request to
set a faster rate). The old baud rate setting code was somewhat
fragile; this change also hopefully makes it easier in the future to
better checking / limiting.

the kernel would be oops'ed before reaching this point anyway. (And
it's really pointless here anyway; if this pointer somehow is NULL the
driver is going to have serious problems in many other places.)

cypress_m8: Packet format is separate from characteristic size
The Cypress app note states that when using an 8 byte packet buffer
size that the packet format is modified (to be more compact). However
I have since discovered that newer DeLorme Earthmate LT-20 devices
(those that are low speed USB with 8 byte packet size) STILL use the
format that is really supposed to correspond to 32 byte packets.
Further confusing things is the subsequent discovery that there are
actually two different types of LT-20 - older LT-20's use 32 byte
packets which is probably why this issue wasn't originally
encountered. The solution here is to flag the packet format
separately from the buffer size. Then at initialization time,
identify the correct combination and set it up. This is a critical
fix for anyone with a newer LT-20. Older devices and non-Earthmate
devices should remain unaffected by this change. (If other devices
behave in this, uh, unexpected manner, it's now just a simple 1 line
change to fix them as well (change the pkt_fmt member for that
device). Default behavior with this patch is still to drive the
format as per the app-note; of course for Earthmate devices this is
overridden.

cypress_m8: Feature buffer fixes
From: Mike Isely <isely@pobox.com>
Don't hardcode the feature buffer size; use sizeof() instead. That
way we can easily specify the size in a single spot. Speaking of the
feature buffer size, the Cypress app note (and further testing with a
DeLorme Earthmate) suggests that this size should be 5 not 8 bytes.

commit 063a2da8f0. The initialization
of the keyspan usb_serial_driver structs were not initializing the
num_interrupt_out field and the additional checking was rejecting
the end point so the driver wouldn't finish initializing.

The changes introduced in commit
063a2da8f0 changed the semantics of the
num_interrupt_in, num_interrupt_out, num_bulk_in and num_bulk_out
entries of the usb_serial_driver struct to be the number of endpoints
the device has when probed.
This patch changes the ti_1port_device usb_serial_driver struct to
reflect this change. The single port devices only have 1
bulk_out endpoint in their initial configuration, and so this patch
changes the number of other types to NUM_DONT_CARE.
The same change probably needs doing to the ti_2port_device struct,

Without this fix, the pl2303 usb-serial adapter would not suspend properly

This was broken before, and a reset resume does not fix it. All other suspend

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):

I work with a group of people on a free home automation tool called
FHEM. Some of the users own more than one USB-serial device by ELV. The
ftdi_sio driver has most of the ELV devices disabled by default and
needs to be re-enabled every time you get a new kernel. Additionally a
new device (EM 1010 PC - enegry monitor) is missing in the list.
Currently our users have to follow the instructions we provide at
http://www.koeniglich.de/fhem/linux.html ... However, to some users it
is too complicated to compile their own kernel module.
We are aware that you can specify one additional device using the
vendor/product option of the module. But lot's of users own more than
one device.

Cleaning out all the incorrect 'no change made' checks for termios
settings showed up a problem with the PL2303. The hardware here seems to
lose sync and bits if you tell it to make no changes. This shows up with
a real world application.
To fix this the driver check for meaningful hardware changes is restored
but doing the tests correctly and as a tty layer function so it doesn't
get duplicated wrongly everywhere if other drivers turn out to need it.

This patch (as997) fixes a bug in the USB serial core. The core needs
to pay attention to drivers' requirements regarding the number and
type of endpoints a device has.
At the same time, the patch changes the NUM_DONT_CARE constant (which
is stored in a single-byte field) from -1 to a safer, unsigned value.
It also improves the kerneldoc for several fields in the
usb_serial_driver structure.
Finally, the patch replaces a list_for_each() with list_for_each_entry().

Some usb-serial devices (e.g. certain Edgeport models) have more than
one serial port on the same USB device/interface.
Currently the only way to distinguish these ports in userspace is by
their minor device number: the driver makes them consecutive and in
stable order.
However, for the purpose of stable naming with udev this is
insufficient: when udev handles the ADD event for one of the ports it
doesn't know what minor number the other one has.
To make stable naming easier, export the port number via sysfs.

This patch contains two fixes submitted by Ondrej Palkovsky:
- the 'ACK' packet is sent after the transfer of the USB packet is
completed, i.e. in the write_callback function. Because the close
function sends the 'abort' command, a parameter is added that allows
the caller of garmin_write_bulk to specify, if the 'ack' should be
propagated to the serial link or dimissed.
This fixes the problem with gpsbabel, it has sent several packets that
were acknowledged before they were sent to the GPS and GpsBabel closed
the device - thus effectively cancelled all outstanding requests in the
queue.
- removed the APP_RESP_SEEN and APP_REQ_SEEN flags and changed
them into counters. It evades USB reset of the gps on every device close.

Coverity is right. The check for NULL is wrongly done and the error
return is lost.

Coverity scan found (CID: 1708) this in
drivers/usb/serial/io_ti.c::edge_shutdown() :
...
2797 for (i=0; i < serial->num_ports; ++i) {
2798 edge_port = usb_get_serial_port_data(serial->port[i]);
2799 edge_remove_sysfs_attrs(edge_port->port);
2800 if (edge_port) {
2801 edge_buf_free(edge_port->ep_out_buf);
2802 kfree(edge_port);
2803 }
2804 usb_set_serial_port_data(serial->port[i], NULL);
2805 }
...
It's complaining that we dereference 'edge_port' in line 2799 which
makes the test of that pointer against NULL in 2800 pointless, since if
edge_port was actually NULL we'd have crashed already before reaching
line 2800.
Reading the edge_open() function it seems to me that the pointer
returned by usb_get_serial_port_data(serial->port[i]) and stored in
'edge_port' can never actually be NULL here, so the test is entirely
superfluous (even if it could be NULL it would be pointless here,
ignoring the then possible crash in that case, since both
edge_buf_free() and kfree() can handle being passed NULL pointers.
This patch removes the pointless conditional (and also makes a few
tiny style corrections now that I was in the area anyway).

Coverity (1709, 1710, 1711, 1712, 1713) actually flagged these as
REVERSE_INULLs (NULL check performed after dereference). But looking at
the other drivers I can't see any similar tests and the USB core already
makes sure urb is non-null - so might as well get rid of the checks.

the new buffering removes the need for the uglies involved - fix them
- Style

The driver now has some style, but not a lot - it goes insane if you have

This removes the ugly code that was copied from the keyspan driver and
allocates the in urbs in a much shorter code path that can be understood
easier.
Also turned off the interrupt urb when no port was open as it's not nice
to keep the bus busy for no good reason at all (this should be a power
savings.)
All in all, this saved over 40 lines of code and cleaned things up
better.

You can't rely on the fact that the status really is correct like it was.
Also simplified the write path and now we allocate the urb and data on
the fly, instead of trying to do that really odd timeout check which I
am guessing doesn't really work properly. This should speed up the
device by keeping the hardware queue full easier.
As a benefit, this reduces the size of the driver.

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.

I had to fiddle a little with the settings in .gnokiirc but that also
occurred with the older 2.6.18 kernel. Nevertheless, on one system with this
cable and my Nokia 6070 I had best results with :
model = 6510
connection = dku5
while on an other system with the same kernel, cable and phone it only worked
with :
model = AT
connection = serial

This patch adds the USB ID of the ADS Tech USBX-707 USB IR blaster (that

With this it should be fairly straightforward to make at least lirc

I encountered some problems with the airprime driver in use with a Novatel
Merlin XU870:
Closing an open Connection to e.g. /dev/ttyUSB0 doesn't reset the
RTS/DTR lines of the Modem. Consequently, when I use minicom to
establish a connection by "ATD*99#" the modem doesn't hang up even if i
exit minicom and so I cannot reuse the modem unless I remove it and plug
it in again.
With the attached patch, the RTS/DTR lines are resetted on a close. The
code was mainly taken from the option.c driver.
Convert all the port specific code in attach / shutdown to use the new
port_probe / port_register callbacks from device_register /
device_unregister allowing adding the sysfs attributes to be added at
the correct time and to the serial port device itself, instead of to
the unadorned usb device, avoiding a NULL dereference.

I added two fields to struct usb_serial_port to keep track of the
throttle state. Other usb-serial drivers typically use private data for
such things, but the generic driver can not really do that because some
of its code is also used by other drivers (which may have their own
private data needs).
As it is, I am not sure that this patch is useful in all scenarios.
It is certainly helpful for low-bandwidth devices that can hold their
data in response to throttling. But for devices that pump data in
real-time as fast as possible (webcam, A/D converter, etc), throttling
may actually cause more data loss.

At least the Keyspan USA-19HS USB-to-serial converter supports
two different configurations, one where the input endpoints
have interrupt transfer type and one where they are bulk endpoints.
The default UHCI configuration uses the interrupt input endpoints.
The keyspan driver, OTOH, assumes that the device has only bulk
endpoints (all URBs are initialized by calling usb_fill_bulk_urb
in keyspan.c/ keyspan_setup_urb). This causes the interval field
of the input URBs to have a value of zero instead of one, which
'accidentally' worked with Linux at least up to 2.6.17.11 but
stopped to with 2.6.18, which changed the UHCI support code handling
URBs for interrupt endpoints. The patch below modifies to driver to
initialize its input URBs either as interrupt or as bulk URBs,
depending on the transfertype contained in the associated endpoint
descriptor (only tested with the default configuration) enabling
the driver to again receive data from the serial converter.
Greg K-H reworked the patch.

If you are a tty driver author converting an out of tree driver the only
impact should be termios->ktermios name changes for the speed/property
setting functions from your upper layers.
If you are implementing your own TCGETS function before then your driver
was broken already and its about to get a whole lot more painful for you so
please fix it 8)
Also fill in c_ispeed/ospeed on init for most devices, although the current
code will do this for you anyway but I'd like eventually to lose that extra
paranoia

Hi everyone,
Sorry for the long time response but here is the patch, I think this way should
work, if anyone has any suggestion let me know. What I do now is, in case I
don't have the tty available I reschedule the work, I have tried it and it
works with no problem, I even tried removing the device, and didn't find
anything strange.
