USB: serial: ssu100: fix control-message error handling

2017-05-14T11:32:56Z

commit 1eac5c244f705182d1552a53e2f74e2775ed95d6 upstream. Make sure to detect short control-message transfers rather than continue with zero-initialised data when retrieving modem status and during device initialisation.

USB: ssu100: fix overrun-error reporting

2014-11-19T15:22:22Z

Fix reporting of overrun errors, which should only be reported once using the inserted null character. Fixes: 6b8f1ca5581b ("USB: ssu100: set tty_flags in ssu100_process_packet") Cc: stable Signed-off-by: Johan Hovold

usb: delete non-required instances of include

2014-01-08T23:01:39Z

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. Signed-off-by: Paul Gortmaker Signed-off-by: Greg Kroah-Hartman

USB: serial: clean up ioctl debugging

2014-01-03T20:31:46Z

Remove redundant ioctl debugging from subdrivers. The ioctl request code has already been logged by usb-serial core. Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: serial: make minor allocation dynamic

2013-06-17T20:30:02Z

This moves the allocation of minor device numbers from a static array to be dynamic, using the idr interface. This means that you could potentially get "gaps" in a minor number range for a single USB serial device with multiple ports, but all should still work properly. We remove the 'minor' field from the usb_serial structure, as it no longer makes any sense for it (use the field in the usb_serial_port structure if you really want to know this number), and take the fact that we were overloading a number in this field to determine if we had initialized the minor numbers or not, and just use a flag variable instead. Note, we still have the limitation of 255 USB to serial devices in the system, as that is all we are registering with the TTY layer at this point in time.

USB: ssu100: switch to generic TIOCMIWAIT implementation

2013-03-25T20:52:28Z

Switch to the generic TIOCMIWAIT implementation. This also fixes the issue with processes waiting for modem-status-changes not being woken up at disconnect. Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: ssu100: fix use-after-free in TIOCMIWAIT

2013-03-21T22:59:05Z

Use the port wait queue and make sure to check the serial disconnected flag before accessing private port data after waking up. This is is needed as the private port data (including the wait queue itself) can be gone when waking up after a disconnect. Cc: stable Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman
