* USB: serial: don't call release without attachAlan Stern2009-10-09
| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following commit made console open fails while booting: commit b50989dc444599c8b21edc23536fc305f4e9b7d5 Author: Alan Cox <alan@linux.intel.com> Date: Sat Sep 19 13:13:22 2009 -0700 tty: make the kref destructor occur asynchronously Due to tty release routines run in a workqueue now, error like the following will be reported while booting: INIT open /dev/console Input/output error It also causes hibernation regression to appear as reported at http://bugzilla.kernel.org/show_bug.cgi?id=14229 The reason is that now there's latency issue with closing, but when we open a "closing not finished" tty, -EIO will be returned. Fix it as per the following Alan's suggestion: Fun but it's actually not a bug and the fix is wrong in itself as the port may be closing but not yet being destructed, in which case it seems to do the wrong thing. Opening a tty that is closing (and could be closing for long periods) is supposed to return -EIO. I suspect a better way to deal with this and keep the old console timing is to split tty->shutdown into two functions. tty->shutdown() - called synchronously just before we dump the tty onto the waitqueue for destruction tty->cleanup() - called when the destructor runs. We would then do the shutdown part which can occur in IRQ context fine, before queueing the rest of the release (from tty->magic = 0 ... the end) to occur asynchronously The USB update in -next would then need a call like if (tty->cleanup) tty->cleanup(tty); at the top of the async function and the USB shutdown to be split between shutdown and cleanup as the USB resource cleanup and final tidy cannot occur synchronously as it needs to sleep. In other words the logic becomes final kref put make object unfindable async clean it up Signed-off-by: Dave Young <hidave.darkstar@gmail.com> [ rjw: Rebased on top of 2.6.31-git, reworked the changelog. ] Signed-off-by: "Rafael J.

* USB-serial: pl2303: fix baud rate handling in case of unsupported valuesFrank Schaefer2009-09-23
| | | | | | | | | | | | | | | | | | | | | | According to the datasheets, the PL2303 supports a set of 25 baudrates. The baudrate is set as a 4 byte value directly. During my experiments with device 067b:2303 (PL2303X), I noticed that - the bridge-controller always uses 9600 baud if invalid/unsupported baud rate values are set - the baud rate value returned by usb_control_msg(..., GET_LINE_REQUEST, ...) does not reflect the actually used baudrate. Always the last set value is returned, even if it was invalid and not used by the controller. This patch fixes the following issues with the current code: 1.) make sure that only supported baudrates are set (are there any buggy chip revisions out there which don't "like" other values... ?). 2.) always set the baudrate to the next nearest supported baudrate. 3.) applications can now read back the resulting baudrate properly, because tty_encode_baud_rate(...) is now fed with the actually used baudrate.

* USB: use kfifo to buffer usb-generic serial writesDavid VomLehn2009-09-23
| | | | | | | | | | | | | | | | | | When do_output_char() attempts to write a carriage return/line feed sequence, it first checks to see how much buffer room is available. If there are at least two characters free, it will write the carriage return/line feed with two calls to tty_put_char(). It calls the tty_operation functions write() for devices that don't support the tty_operations function put_char(). If the USB generic serial device's write URB is not in use, it will return the buffer size when asked how much room is available. The write() of the carriage return will cause it to mark the write URB busy, so the subsequent write() of the line feed will be ignored. This patch uses the kfifo infrastructure to implement a write FIFO that accurately returns the amount of space available in the buffer.

* USB serial: update the console driverAlan Stern2009-09-19
| | | | | | | | | | | | | | | | | | | | | | | | This patch (as1292) modifies the USB serial console driver, to make it compatible with the recent changes to the USB serial core. The most important change is that serial->disc_mutex now has to be unlocked following a successful call to usb_serial_get_by_index(). Other less notable changes include: Use the requested port number instead of port 0 always. Prevent the serial device from being autosuspended. Use the ASYNCB_INITIALIZED flag bit to indicate when the port hardware has been initialized. In spite of these changes, there's no question that the USB serial console code is still a big hack.

| | | | | | | | | | | | | | | This patch (as1291) removes a bunch of code from serial_open(), things that were rendered unnecessary by earlier patches. A missing spinlock is added to protect port->port.count, which needs to be incremented even if the open fails but not if the tty has gotten a hangup. The test for whether the hardware has been initialized, based on the use count, is replaced by a more transparent test of the ASYNCB_INITIALIZED bit in the port flags.

* usb-serial: acquire references when a new tty is installedAlan Stern2009-09-19
| | | | | | | | | | | | | | | | | This patch (as1287) makes serial_install() be reponsible for acquiring references to the usb_serial structure and the driver module when a tty is first used. This is more sensible than having serial_open() do it, because a tty can be opened many times whereas it is installed only once, when it is created. (Not to mention that these actions are reversed when the tty is released, not when it is closed.) Finally, it is at install time that the TTY core takes its own reference to the usb_serial module, so it is only fitting that we should act the same way in regard to the lower-level serial driver.

* usb-serial: change logic of serial lookupsAlan Stern2009-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1286) changes usb_serial_get_by_index(). Now the routine will check whether the serial device has been disconnected; if it has then the return value will be NULL. If the device hasn't been disconnected then the routine will return with serial->disc_mutex held, so that the caller can use the structure without fear of racing against driver unloads. This permits the scope of table_mutex in destroy_serial() to be reduced. Instead of protecting the entire function, it suffices to protect the part that actually uses serial_table[], i.e., the call to return_serial(). There's no longer any danger of the refcount being incremented after it reaches 0 (which was the reason for having the large scope previously), because it can't reach 0 until the serial device has been disconnected. Also, the patch makes serial_install() check that serial is non-NULL before attempting to use it.

* usb-serial: change referencing of port and serial structuresAlan Stern2009-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1284) changes the referencing of the usb_serial and usb_serial_port structures in usb-serial.c. It's not feasible to make the port structures keep a reference to the serial structure, because the ports need to remain in existence when serial is released -- quite a few of the drivers expect this. Consequently taking a reference to the port when the device file is open is insufficient; such a reference would not pin serial. To fix this, we now take a reference to serial when the device file is opened. The final put_device() for the ports occurs in destroy_serial(), so that the ports will last as long as they are needed. The patch initializes all the port devices, including those in the unused "fake" ports. This makes the code more uniform because they can all be released in the same way. The error handling code in usb_serial_probe() is much simplified by this approach; instead of freeing everything by hand we can use a single usb_serial_put() call. Also simplified is the port-release mechanism. Instead of being two separate routines, port_release() and port_free() can be combined into one.
