2009-09-19USB serial: update the console driverAlan Stern1-9/+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.

2009-09-19usb-serial: straighten out serial_openAlan Stern1-37/+22
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.

2009-09-19usb-serial: add missing tests and debug linesAlan Stern1-4/+17
This patch (as1290) adds some missing tests. serial_down() isn't supposed to do anything if the hardware hasn't been initialized, and serial_close() isn't supposed to do anything if the tty has gotten a hangup (because serial_hangup() takes care of shutting down the hardware). The patch also updates and adds a few debugging lines. Signed-off-by: Alan Stern <[email protected]> Cc: stable <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2009-09-19usb-serial: rename subroutinesAlan Stern1-8/+11
This patch (as1289) renames serial_do_down() to serial_down() and serial_do_free() to serial_release(). It also adds a missing call to tty_shutdown() in serial_release().

2009-09-19usb-serial: fix termios initialization logicAlan Stern1-12/+10
This patch (as1288) fixes the initialization logic in serial_install(). A new tty always needs to have a termios initialized no matter what, not just in the case where the lower driver will override the termios settings.

2009-09-19usb-serial: acquire references when a new tty is installedAlan Stern1-64/+47
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.

2009-09-19usb-serial: change logic of serial lookupsAlan Stern1-8/+23
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.

2009-09-19usb-serial: put subroutines in logical orderAlan Stern1-77/+77
This patch (as1285) rearranges the subroutines in usb-serial.c concerned with tty lifetimes into a more logical order: install, open, hangup, close, release. It also updates the formatting of the kerneldoc comments. Signed-off-by: Alan Stern <[email protected]> Cc: stable <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2009-09-19usb-serial: change referencing of port and serial structuresAlan Stern1-75/+20
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.

2009-09-19tty: USB hangup is racyAlan Cox1-4/+1
The USB layer uses tty_hangup to deal with unplugs of the physical hardware (analogous to loss of carrier) and then frees the resources. However the tty_hangup is asynchronous. As the hangup can sleep we can use tty_vhangup which is the non async version to avoid freeing resources too early.
