USB: usbserial - fix potential deadlock between write() and IRQ

2007-11-16T17:30:23+00:00

patch acd2a847e7fee7df11817f67dba75a2802793e5d in mainline.

USB: usbserial - fix potential deadlock between write() and IRQ

usb_serial_generic_write() doesn't disable interrupts when taking port->lock,
and could therefore deadlock with usb_serial_generic_read_bulk_callback()
being called from interrupt, taking the same lock. Fix it.

USB: drivers/usb/serial/bus.c: Fix incompatible pointer type warning

2007-09-11T14:48:17+00:00

drivers/usb/serial/bus.c: In function usb_serial_bus_deregister:
drivers/usb/serial/bus.c:185:
warning: passing argument 1 of free_dynids from incompatible pointer type

Above build warning comes when CONFIG_HOTPLUG=n because argument of
free_dynids() in serial/bus.c is a struct usb_serial_driver, not a
struct usb_driver. This is not a runtime bug, because the function
is an empty stub and never dereferences the passed pointer anyway.

usb-serial: fix oti6858.c segfault in termios handling

2007-08-22T21:27:48+00:00

The oti6858 usb serial driver should use kernel_termios_to_user_termios/
user_termios_to_kernel_termios to avoid segfaults because the kernel
uses a structure differing from that of user space with a different
size.

USB: belkin_sa: avoid divide by zero error

2007-08-22T21:27:46+00:00

The belkin_sa module has a problem coping with a 0 return from
tty_get_baud_rate() -- the subsequent BELKIN_SA_BAUD macro

drivers/usb/serial/belkin_sa.h:#define BELKIN_SA_BAUD(b) (230400/b)

performs a divide with it leading to the following divide error:

The small patch below should take care of this situation.  Note that my
kernel was tainted (vmware) but the problem will occur if
tty_get_baud_rate() ever returns zero and should be taken care of.
