2019-04-30USB: serial: fix unthrottle racesJohan Hovold1-7/+32
Fix two long-standing bugs which could potentially lead to memory corruption or leave the port throttled until it is reopened (on weakly ordered systems), respectively, when read-URB completion races with unthrottle(). First, the URB must not be marked as free before processing is complete to prevent it from being submitted by unthrottle() on another CPU. CPU 1 CPU 2 ================ ================ complete() unthrottle() process_urb(); smp_mb__before_atomic(); set_bit(i, free); if (test_and_clear_bit(i, free)) submit_urb(); Second, the URB must be marked as free before checking the throttled flag to prevent unthrottle() on another CPU from failing to observe that the URB needs to be submitted if complete() sees that the throttled flag is set. CPU 1 CPU 2 ================ ================ complete() unthrottle() set_bit(i, free); throttled = 0; smp_mb__after_atomic(); smp_mb(); if (throttled) if (test_and_clear_bit(i, free)) return; submit_urb(); Note that test_and_clear_bit() only implies barriers when the test is successful. To handle the case where the URB is still in use an explicit barrier needs to be added to unthrottle() for the second race condition.

2019-04-26USB: serial: fix initial-termios handlingJohan Hovold1-4/+7
The USB-serial driver init_termios callback is used to override the default initial terminal settings provided by USB-serial core. After a bug was fixed in the original implementation introduced by commit fe1ae7fdd2ee ("tty: USB serial termios bits"), the init_termios callback was no longer called just once on first use as intended but rather on every (first) open. This specifically meant that the terminal settings saved on (final) close were ignored when reopening a port for drivers overriding the initial settings.
