tty: Replace ASYNC_INITIALIZED bit and update atomically

2016-04-30T16:26:55+00:00

Replace ASYNC_INITIALIZED bit in the tty_port::flags field with
TTY_PORT_INITIALIZED bit in the tty_port::iflags field. Introduce helpers
tty_port_set_initialized() and tty_port_initialized() to abstract
atomic bit ops.

Note: the transforms for test_and_set_bit() and test_and_clear_bit()
are unnecessary as the state transitions are already mutually exclusive;
the tty lock prevents concurrent open/close/hangup.

cdc-acm: fix crash if flushed with nothing buffered

2016-04-13T18:53:07+00:00

Under some circumstances acm_tty_flush_chars() is called
with no buffer to flush. We simply need to do nothing.

USB: cdc-acm: more sanity checking

2016-03-18T16:19:02+00:00

An attack has become available which pretends to be a quirky
device circumventing normal sanity checks and crashes the kernel
by an insufficient number of interfaces. This patch adds a check
to the code path for quirky devices.

cdc-acm: implement put_char() and flush_chars()

2016-02-15T01:06:43+00:00

This should cut down latencies and waste if the tty layer writes single bytes.

cdc-acm:exclude Samsung phone 04e8:685d

2016-01-25T05:06:21+00:00

and is reported to crash irrevocably if cdc-acm takes it.

usb: cdc-acm: send zero packet for intel 7260 modem

2016-01-25T05:06:21+00:00

For Intel 7260 modem, it is needed for host side to send zero
packet if the BULK OUT size is equal to USB endpoint max packet
length. Otherwise, modem side may still wait for more data and
cannot give response to host side.
