usb-serial: replace shutdown with disconnect, release

2009-07-02T23:50:25Z

commit f9c99bb8b3a1ec81af68d484a551307326c2e933 upstream This patch splits up the shutdown method of usb_serial_driver into a disconnect and a release method. The problem is that the usb-serial core was calling shutdown during disconnect handling, but drivers didn't expect it to be called until after all the open file references had been closed. The result was an oops when the close method tried to use memory that had been deallocated by shutdown. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: removal of tty->low_latency hack dating back to the old serial code

2009-04-23T21:15:29Z

This removes tty->low_latency from all USB serial drivers that push data into the tty layer at hard interrupt context. It's no longer needed and actually harmful. Signed-off-by: Oliver Neukum Cc: Alan Cox Signed-off-by: Greg Kroah-Hartman

USB: serial: export symbol of usb_serial_generic_resume

2009-03-24T23:20:29Z

This exports a symbol for usb_serial_generic_resume, so that modules can use it. Signed-off-by: Oliver Neukum Signed-off-by: Greg Kroah-Hartman

USB: serial generic resume function fix

2009-03-24T23:20:29Z

This removes an unnecessary check for autoresume from the generic resume method. The check has been obsoleted by the now delayed increase of the usage counter which makes the error this check prevented impossible. This change allows drivers which only use the bulk read URB the use of the generic method even if they support autosuspend. Signed-off-by: Oliver Neukum Signed-off-by: Greg Kroah-Hartman

tty: usb-serial krefs

2008-10-13T16:51:41Z

Use kref in the USB serial drivers so that we don't free tty structures from under the URB receive handlers as has historically been the case if you were unlucky. This also gives us a framework for general tty drivers to use tty_port objects and refcount. Contains two err->dev_err changes merged together to fix clashes in the -next tree.

usb_serial: API all change

2008-07-22T20:03:22Z

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 Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman Signed-off-by: Linus Torvalds

usb serial: more fixes and groundwork for tty changes

2008-04-25T04:16:55Z

- If a termios change fails due to lack of memory we should copy the old settings back over as the device has not changed - Note various locking problems - kl5kusb105 had various remaining tty flag handling problems - Make safe_serial use tty_insert_flip_string not open coded loops - set termios speed properly in usb_serial Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman
