net: ircomm, cleanup TIOCGSERIAL

2016-06-25T15:56:30+00:00

In ircomm_tty_get_serial_info, struct serial_struct is memset to 0 and
then some members set to 0 explicitly.

Remove the latter as it is obviously superfluous.

And remove the retinfo check against NULL. copy_to_user will take care
of that.

Part of hub6 cleanup series.

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.

tty: Replace ASYNC_CHECK_CD and update atomically

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

Replace ASYNC_CHECK_CD bit in the tty_port::flags field with
TTY_PORT_CHECK_CD bit in the tty_port::iflags field. Introduce helpers
tty_port_set_check_carrier() and tty_port_check_carrier() to abstract
the atomic bit ops.

tty: Replace ASYNC_NORMAL_ACTIVE bit and update atomically

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

Replace ASYNC_NORMAL_ACTIVE bit in the tty_port::flags field with
TTY_PORT_ACTIVE bit in the tty_port::iflags field. Introduce helpers
tty_port_set_active() and tty_port_active() to abstract atomic bit ops.

Extract state changes from port lock sections, as this usage is
broken and confused; the state transitions are protected by the
tty lock (which mutually excludes parallel open/close/hangup),
and no user tests the active state while holding the port lock.

tty: Replace ASYNC_CTS_FLOW bit and update atomically

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

Replace ASYNC_CTS_FLOW bit in the tty_port::flags field with
TTY_PORT_CTS_FLOW bit in the tty_port::iflags field. Add
tty_port_set_cts_flow() helper to abstract the atomic bit ops.

tty: Replace TTY_THROTTLED bit tests with tty_throttled()

tty: Replace TTY_IO_ERROR bit tests with tty_io_error()

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

Abstract TTY_IO_ERROR status test treewide with tty_io_error().
NB: tty->flags uses atomic bit ops; replace non-atomic bit test
with test_bit().

irda: fix a potential use-after-free in ircomm_param_request

2016-01-30T06:56:46+00:00

self->ctrl_skb is protected by self->spinlock, we should not
access it out of the lock. Move the debugging printk inside.

tty: Remove ASYNC_CLOSING

2016-01-28T22:19:12+00:00

The tty core no longer provides nor uses ASYNC_CLOSING; remove from
tty_port_close_start() and tty_port_close_end() as well as tty drivers
which open-code these state changes. Unfortunately, even though the
bit is masked from userspace, its inclusion in a uapi header precludes
removing the macro.
