-2001-08-11  Tim Waugh  <twaugh@redhat.com>
-
-        * serial.c (get_pci_port): Deal with awkward Titan cards.
-
-1998-08-26  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * serial.c (rs_open): Correctly decrement the module in-use count
-                on errors.
-
-Thu Feb 19 14:24:08 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * tty_io.c (tty_name): Remove the non-reentrant (and non-SMP safe)
-                version of tty_name, and rename the reentrant _tty_name
-                function to be tty_name.
-                (tty_open): Add a warning message stating callout devices
-                are deprecated.
-
-Mon Dec  1 08:24:15 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * tty_io.c (tty_get_baud_rate): Print a warning syslog if the
-                tty->alt_speed kludge is used; this means the system is
-                using the deprecated SPD_HI ioctls.
-
-Mon Nov 24 10:37:49 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * serial.c, esp.c, rocket.c: Change drivers to take advantage of
-                tty_get_baud_rate().
-        
-        * tty_io.c (tty_get_baud_rate): New function which computes the
-                correct baud rate for the tty.  More factoring out of
-                common code out of the serial driver to the high-level tty
-                functions....
-
-Sat Nov 22 07:53:36 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * serial.c, esp.c, rocket.c: Add tty->driver.break() routine, and
-                allow high-level tty code to handle the break and soft
-                carrier ioctls.
-        
-        * tty_ioctl.c (n_tty_ioctl): Support TIOCGSOFTCAR and
-                TIOCSSOFTCAR, so that device drivers don't have to support
-                it.
-
-        * serial.c (autoconfig): Change 16750 test to hopefully eliminate
-                false results by people with strange 16550As being
-                detected as 16750s.  Hopefully 16750s will still be
-                detected as 16750, and other weird UARTs won't get poorly
-                autodetected.  If this doesn't work, I'll have to disable
-                the auto identification for the 16750.
-
-        * tty_io.c (tty_hangup): Now actually do the tty hangup
-                processing during the timer processing, and disable
-                interrupts while doing the hangup processing.  This avoids
-                several nasty race conditions which happened when the
-                hangup processing was done asynchronously.
-                (tty_ioctl): Do break handling in the tty driver if
-                driver's break function is supported.  
-                (tty_flip_buffer_push): New exported function which should
-                be used by drivers to push characters in the flip buffer
-                to the tty handler.  This may either be done using a task
-                queue function for better CPU efficiency, or directly for
-                low latency operation.
-
-        * serial.c (rs_set_termios): Fix bug rs_set_termios when
-                transitioning away from B0, submitted by Stanislav
-                Voronyi. 
-
-Thu Jun 19 20:05:58 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * serial.c (begin_break, end_break, rs_ioctl): Applied patch
-                to support BSD ioctls to set and clear the break
-                condition explicitly.
-
-        * console.c (scrup, scrdown, insert_line, delete_line): Applied
-                fix suggested by Aaron Tiensivu to speed up block scrolls
-                up and down.
-
-        * n_tty.c (opost_block, write_chan): Added a modified "fast
-                console" patch which processes a block of text via
-                "cooking" efficiently.
-
-Wed Jun 18 15:25:50 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * tty_io.c (init_dev, release_dev): Applied fix suggested by Bill
-                Hawes to prevent race conditions in the tty code.
-
-        * n_tty.c (n_tty_chars_in_buffer): Applied fix suggested by Bill
-                Hawes so that n_tty_chars_in_buffer returns the correct
-                value in the case when the tty is in cannonical mode.  (To
-                avoid a pty deadlock with telnetd.)
-
-Thu Feb 27 01:53:08 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * serial.c (change_speed): Add support for the termios flag
-                CMSPAR, which allows the user to select stick parity.
-                (i.e, if PARODD is set, the parity bit is always 1; if
-                PARRODD is not set, then the parity bit is always 0).
-
-Wed Feb 26 19:03:10 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * serial.c (cleanup_module): Fix memory leak when using the serial
-                driver as a module; make sure tmp_buf gets freed!
-
-Tue Feb 25 11:01:59 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * serial.c (set_modem_info): Add support for setting and clearing
-                the OUT1 and OUT2 bits.  (For special case UART's, usually
-                for half-duplex.)
-                (autoconfig, change_speed): Fix TI 16750 support.
-
-Sun Feb 16 00:14:43 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * tty_io.c (release_dev): Add sanity check to make sure there are
-                no waiters on tty->read_wait or tty->write_wait.
-
-        * serial.c (rs_init): Don't autoconfig a device if the I/O region
-                is already reserved.
-
-        * serial.c (serial_proc_info): Add support for /proc/serial.
-
-Thu Feb 13 00:49:10 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * serial.c (receive_chars): When the UART repotrs an overrun
-                condition, it does so with a valid character.  Changed to
-                not throw away the valid character, but instead report the
-                overrun after the valid character.
-
-        * serial.c: Added new #ifdef's for some of the advanced serial
-                driver features.  A minimal driver that only supports COM
-                1/2/3/4 without sharing serial interrupts only takes 17k;
-                the full driver takes 32k.
-                
-Wed Feb 12 14:50:44 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * vt.c:
-        * pty.c: 
-        * tty_ioctl.c: 
-        * serial.c: Update routines to use the new 2.1 memory access
-                routines.
-
-Wed Dec  4 07:51:52 1996  Theodore Ts'o  <tytso@localhost.mit.edu>
-
-        * serial.c (change_speed): Use save_flags(); cli() and
-                restore_flags() in order to ensure we don't accidentally
-                turn on interrupts when starting up the port.
-                (startup): Move the insertion of serial structure into the
-                IRQ chain earlier into the startup processing.  Interrupts
-                should be off this whole time, but we eventually will want
-                to reduce this window.
-
-Thu Nov 21 10:05:22 1996  Theodore Ts'o  <tytso@localhost.mit.edu>
-
-        * tty_ioctl.c (tty_wait_until_sent): Always check the driver
-                wait_until_ready routine, even if there are no characters
-                in the xmit buffer.  (There may be charactes in the device
-                FIFO.)
-                (n_tty_ioctl): Add new flag tty->flow_stopped which
-                indicates whether the tty is stopped due to a request by
-                the TCXONC ioctl (used by tcflow).  If so, don't let an
-                incoming XOFF character restart the tty.  The tty can only
-                be restarted by another TCXONC request.
-
-        * tty_io.c (start_tty): Don't allow the tty to be restarted if
-                tty->flow_stopped is true.
-
-        * n_tty.c (n_tty_receive_char): If tty->flow_stopped is true, and
-                IXANY is set, don't eat a character trying to restart the
-                tty.
-
-        * serial.c (startup): Remove need for MCR_noint from the
-                async_struct structure.  Only turn on DTR and RTS if the
-                baud rate is not zero.
-                (change_speed): More accurately calculate the timeout
-                value based on the word size.  Move responsibility of
-                hangup when speed becomes B0 to rs_set_termios()
-                (set_serial_info): When changing the UART type set the
-                current xmit_fifo_size as well as the permanent
-                xmit_fifo_size.
-                (rs_ioctl): Fix TCSBRK (used by tcdrain) and TCSBRKP
-                ioctls to return EINTR if interrupted by a signal.
-                (rs_set_termios): If the baud rate changes to or from B0,
-                this function is now responsible for setting or clearing
-                DTR and RTS.  DTR and RTS are only be changed on the
-                transition to or from the B0 state.
-                (rs_close): Wait for the characters to drain based on
-                info->timeout.  At low baud rates (50 bps), it may take a
-                long time for the FIFO to completely drain out!
-                (rs_wait_until_sent): Fixed timeout handling.  Now
-                releases control to the scheduler, but checks frequently
-                enough so that the function is sensitive enough to pass
-                the timing requirements of the NIST-PCTS.
-                (block_til_ready): When opening the device, don't turn on
-                DTR and RTS if the baud rate is B0.
-
-Thu Nov 14 00:06:09 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * serial.c (autoconfig): Fix autoconfiguration problems;
-                info->flags wasn't getting initialized from the state
-                structure.  Put in more paranoid test for the 16750.
-
-Fri Nov  8 20:19:50 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * n_tty.c (n_tty_flush_buffer): Only call driver->unthrottle() if
-                the tty was previous throttled.
-                (n_tty_set_termios, write_chan): Add changes suggested by
-                        Simon P. Allen to allow hardware cooking.
-
-        * tty_ioctl.c (set_termios): If we get a signal while waiting for
-                the tty to drain, return -EINTR.
-        
-        * serial.c (change_speed): Add support for CREAD, as required by
-                POSIX.
-
-Sat Nov  2 20:43:10 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * serial.c: Wholesale changes.  Added support for the Startech
-                16650 and 16650V2 chips.  (WARNING: the new startech
-                16650A may or may not work!)  Added support for the
-                TI16750 (not yet tested).  Split async_struct into a
-                transient part (async_struct) and a permanent part
-                (serial_state) which contains the configuration
-                information for the ports.  Added new driver routines
-                wait_until_sent() and send_xchar() to help with POSIX
-                compliance.  Added support for radio clocks which waggle
-                the carrier detect line (CONFIG_HARD_PPS).
-        
-        * tty_ioctl.c (tty_wait_until_sent): Added call to new driver
-                function tty->driver.wait_until_sent(), which returns when
-                the tty's device xmit buffers are drained.  Needed for
-                full POSIX compliance.
-
-                (send_prio_char): New function, called by the ioctl's
-                TCIOFF and TCION; uses the new driver call send_xchar(),
-                which will send the XON or XOFF character at high priority
-                (and even if tty output is stopped).
-
-Wed Jun  5 18:52:04 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * pty.c (pty_close): When closing a pty, make sure packet mode is
-                cleared.
-
-Sun May 26 09:33:52 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * vesa_blank.c (set_vesa_blanking): Add missing verify_area() call.
-
-        * selection.c (set_selection): Add missing verify_area() call.
-
-        * tty_io.c (tty_ioctl): Add missing verify_area() calls.
-
-        * serial.c (rs_ioctl): Add missing verify_area() calls.
-                (rs_init): Allow initialization of serial driver
-                configuration from a module.
-
-        * random.c (extract_entropy): Add missing verify_area call.
-                Don't limit number of characters returned to
-                32,768. Extract entropy is now no longer a inlined
-                function.
-
-                (random_read): Check return value in case extract_entropy
-                returns an error.
-
-                (secure_tcp_sequence_number): New function which returns a
-                secure TCP sequence number.  This is needed to prevent some
-                nasty TCP hijacking attacks.
-        
-                (init_std_data): Initialize using gettimeofday() instead of
-                struct timeval xtime.
-
-                (fast_add_entropy_word, add_entropy_word): Rename the
-                inline function add_entropy_word() to
-                fast_add_entropy_word().  Make add_entropy_word() be the
-                non-inlined function which is used in non-timing critical
-                places, in order to save space.
-
-                (initialize_benchmark, begin_benchmark, end_benchmark): New
-                functions defined when RANDOM_BENCHMARK is defined.  They
-                allow us to benchmark the speed of the
-                add_timer_randomness() call.
-
-                (int_ln, rotate_left): Add two new inline functions with
-                i386 optimized asm instructions.  This speeds up the
-                critical add_entropy_word() and add_timer_randomness()
-                functions, which are called from interrupt handlers.
-
-Tue May  7 22:51:11 1996    <tytso@rsts-11.mit.edu>
-
-        * random.c (add_timer_randomness): Limit the amount randomness
-                that we estimate to 12 bits.  (An arbitrary amount).
-
-                (extract_entropy): To make it harder to analyze the hash
-                function, fold the hash function in half using XOR, and
-                use the folded result as the value to emit to the user.
-                Also, add timer randomness each pass through the
-                exact_entropy call, to increase the amount of unknown
-                values during the extraction process.
-
-                (random_ioctl): Use IOR/IOW definitions to define the
-                ioctl values used by the /dev/random driver.  Allow the
-                old ioctl values to be used for backwards compatibility
-                (for a limited amount of time).
-
-Wed Apr 24 14:02:04 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-        * random.c (add_timer_randomness): Use 2nd derivative as well to
-                better estimate entropy.
-
-                (rand_initialize): Explicitly initialize all the pointers
-                to NULL.  (Clearing pointers using memset isn't portable.)
-                Initialize the random pool with OS-dependent data.
-
-                (random_write): Add sanity checking to the arguments to
-                random_write(), so that bad arguments won't cause a kernel
-                SEGV. 
-
-                (random_read): Update the access time of the device inode
-                when you return data to the user.
-
-                (random_ioctl): Wake up the random_wait channel when there
-                are only WAIT_INPUT_BITS available.  Add more paranoia
-                checks to make sure entropy_count doesn't go beyond the
-                bounds of (0, POOLSIZE).  Add a few missing verify_area
-                checks.  Add support for the RNDCLEARPOOL ioctl, which
-                zaps the random pool.
-
-                (add_timer_randomness): Wake up the random_wait
-                channel only when there are WAIT_INPUT_BITS available.
-
-                (random_select): Allow a random refresh daemon process to
-                select on /dev/random for writing; wake up the daemon when
-                there are less than WAIT_OUTPUT_BITS bits of randomness
-                available.

-Tue Apr 23 22:56:07 1996    <tytso@rsts-11.mit.edu>
-
-        * tty_io.c (init_dev): Change return code when user attempts to
-                open master pty which is already open from EAGAIN to EIO,
-                to match with BSD expectations.  EIO is more correct
-                anyway, since EAGAIN implies that retrying will be
-                successful --- which it might be.... Eventually!!
-
-        * pty.c (pty_open, pty_close): Fix wait loop so that we don't
-                busy loop while waiting for the master side to open.
-                Fix tty opening/closing logic.  TTY_SLAVE_CLOSED was
-                renamed to TTY_OTHER_CLOSED, so that the name is more
-                descriptive.  Also fixed code so that the tty flag
-                actually works correctly now....
-
-Mon Apr  1 10:22:01 1996    <tytso@rsts-11.mit.edu>
-
-        * serial.c (rs_close): Cleaned up modularization changes.
-                Remove code which forced line discipline back to N_TTY
-                this is done in the tty upper layers, and there's no
-                reason to do it here.  (Making this change also
-                removed the requirement that the serial module access
-                the internal kernel symbol "ldiscs".)
-
-        * tty_io.c (tty_init): Formally register a tty_driver entry for
-                /dev/tty (device 4, 0) and /dev/console (device 5, 0).
-                This guarantees that major device numbers 4 and 5 will be
-                reserved for the tty subsystem (as they have to be because
-                of /dev/tty and /dev/console).  Removed tty_regdev, as
-                this interface is no longer necessary.
-
-Sun Mar 17 20:42:47 GMT 1996 <ah@doc.ic.ac.uk>
-
-        * serial.c : modularisation (changes in linux/fs/device.c allow
-                kerneld to automatically load the serial module).
-
-        * Makefile, Config.in : serial modularisation adds.
-
-        * tty_io.c : tty_init_ctty used by to register "cua" driver just
-                for the /dev/tty device (5,0).  Added tty_regdev.
-        
-        * serial.c (shutdown, rs_ioctl) : when port shuts down wakeup processes
-          waiting on delta_msr_wait. The TIOCMIWAIT ioctl returns EIO
-          if no change was done since the time of call.
-
-Sat Mar 16 14:33:13 1996 <aeb@cwi.nl>
-
-        * tty_io.c (disassociate_ctty): If disassociate_ctty is called by
-                exit, do not perform an implicit vhangup on a pty.
-
-Fri Feb  9 14:15:47 1996    <tytso@rsts-11.mit.edu>
-
-        * serial.c (block_til_ready): Fixed another race condition which
-                happens if a hangup happens during the open.
-
-Wed Jan 10 10:08:00 1996    <tytso@rsts-11.mit.edu>
-
-        * serial.c (block_til_ready): Remove race condition which happened
-                if a hangup condition happened during the setup of the
-                UART, before rs_open() called block_til_ready().  This
-                caused the info->count counter to be erroneously
-                decremented.
-
-        * serial.c (startup, rs_open): Remove race condition that could
-                cause a memory leak of one page.  (Fortunately, both race
-                conditions were relatively rare in practice.)
-
-Tue Dec  5 13:21:27 1995    <tytso@rsts-11.mit.edu>
-
-        * serial.c (check_modem_status, rs_ioctl): Support the new
-                ioctl()'s TIOCGICOUNT, TIOCMIWAIT.  These allow an
-                application program to wait on a modem serial register
-                status bit change, and to find out how many changes have
-                taken place for the MSR bits.
-
-                (rs_write): Eliminate a race condition which is introduced
-                if it is necessary to wait for the semaphore.
-
-Sat Nov  4 17:14:45 1995    <tytso@rsts-11.mit.edu>
-
-        * tty_io.c (tty_init): Move registration of TTY_MAJOR and
-                TTY_AUX_MAJOR to the end, so that /proc/devices looks
-                prettier. 
-
-        * pty.c (pty_init): Use new major numbers for PTY master and slave
-                devices.  This allow us to have more than 64 pty's.  We
-                register the old pty devices for backwards compatibility.
-                Note that a system should either be using the old pty
-                devices or the new pty devices --- in general, it should
-                try to use both, since they map into the same pty table.
-                The old pty devices are strictly for backwards compatibility.
-
-Wed Oct 11 12:45:24 1995    <tytso@rsts-11.mit.edu>
-
-        * tty_io.c (disassociate_ctty): If disassociate_ctty is called by
-                exit, perform an implicit vhangup on the tty.
-
-        * pty.c (pty_close): When the master pty is closed, send a hangup
-                to the slave pty.
-                (pty_open): Use the flag TTY_SLAVE_CLOSED to test to see
-                if there are any open slave ptys, instead of using
-                tty->link->count.  The old method got confused if there
-                were processes that had hung-up file descriptors on the
-                slave tty.
-
-Tue May  2 00:53:25 1995    <tytso@rsx-11.mit.edu>
-
-        * tty_io.c (tty_set_ldisc): Wait until the output buffer is
-                drained before closing the old line discipline --- needed
-                in only one case: XON/XOFF processing.
-
-        * n_tty.c (n_tty_close): Don't bother waiting until the output
-                driver is closed; in general, the line discipline
-                shouldn't care if the hardware is finished
-                transmitting before the line discipline terminates.
-
-        * tty_io.c (release_dev): Shutdown the line discipline after
-                decrementing the tty count variable; but set the
-                TTY_CLOSING flag so that we know that this tty structure
-                isn't long for this world.
-
-        * tty_io.c (init_dev): Add sanity code to check to see if
-                TTY_CLOSING is set on a tty structure; if so, something
-                bad has happened (probably a line discipline close blocked
-                when it shouldn't have; so do a kernel printk and then
-                return an error).
-
-Wed Apr 26 10:23:44 1995  Theodore Y. Ts'o  <tytso@localhost>
-
-        * tty_io.c (release_dev): Try to shutdown the line discipline
-                *before* decrementing the tty count variable; this removes
-                a potential race condition which occurs when the line
-                discipline close blocks, and another process then tries
-                open the same serial port.
-
-        * serial.c (rs_hangup): When hanging up, flush the output buffer
-                before shutting down the UART.  Otherwise the line
-                discipline close blocks waiting for the characters to get
-                flushed, which never happens until the serial port gets reused.
-
-Wed Apr 12 08:06:16 1995  Theodore Y. Ts'o  <tytso@localhost>
-
-        * serial.c (do_serial_hangup, do_softint, check_modem_status,
-                rs_init):  Hangups are now scheduled via a separate tqueue
-                structure in the async_struct structure, tqueue_hangup.
-                This task is pushed on to the tq_schedule queue, so that
-                it is processed synchronously by the scheduler.
-
-Sat Feb 18 12:13:51 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * tty_io.c (disassociate_ctty, tty_open, tty_ioctl): Clear
-                current->tty_old_pgrp field when a session leader
-                acquires a controlling tty, and after a session leader
-                has disassociated from a controlling tty.
-
-Fri Feb 17 09:34:09 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * serial.c (rs_interrupt_single, rs_interrupt, rs_interrupt_multi): 
-                Change the number of passes made from 64 to be 256,
-                configurable with the #define RS_ISR_PASS_LIMIT.
-
-        * serial.c (rs_init, set_serial_info, get_serial_info, rs_close):
-                Remove support for closing_wait2.  Instead, set
-                tty->closing and rely on the line discipline to prevent
-                echo wars.
-
-        * n_tty.c (n_tty_receive_char):  IEXTEN does not need to be
-                enabled in order for IXANY to be active.
-
-                If tty->closing is set, then only process XON and XOFF
-                characters.
-
-Sun Feb 12 23:57:48 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * serial.c (rs_timer): Change the interrupt poll time from 60
-                seconds to 10 seconds, configurable with the #define
-                RS_STROBE_TIME.
-
-        * serial.c (rs_interrupt_multi, startup, shutdown, rs_ioctl,
-                set_multiport_struct, get_multiport_struct): Add
-                provisions for a new type of interrupt service routine,
-                which better supports multiple serial ports on a single
-                IRQ.  
-
-Sun Feb  5 19:35:11 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * tty_ioctl.c (n_tty_ioctl, set_termios, tty_wait_until_sent): 
-        * serial.c (rs_ioctl, rs_close): 
-        * cyclades.c (cy_ioctl, cy_close): 
-        * n_tty.c (n_tty_close):  Rename wait_until_sent to
-                tty_wait_until_sent, so that it's a better name to export
-                in ksyms.c.
-
-Sat Feb  4 23:36:20 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * serial.c (rs_close): Added missing check for closing_wait2 being
-                ASYNC_CLOSING_WAIT_NONE.
-
-Thu Jan 26 09:02:49 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * serial.c (rs_init, set_serial_info, get_serial_info,
-                rs_close): Support close_wait in the serial driver.
-                This is helpful for slow devices (like serial
-                plotters) so that their outputs don't get flushed upon
-                device close.  This has to be configurable because
-                normally we don't want ports to be hung up for long
-                periods of time during a close when they are not
-                connected to a device, or the device is powered off.
-
-                The default is to wait 30 seconds; in the case of a
-                very slow device, the close_wait timeout should be
-                lengthened.  If it is set to 0, the kernel will wait
-                forever for all of the data to be transmitted.
-
-Thu Jan 17 01:17:20 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * serial.c (startup, change_speed, rs_init): Add support to detect
-                the StarTech 16650 chip.  Treat it as a 16450 for now,
-                because of its FIFO bugs.
-
-Thu Jan  5 21:21:57 1995  <dahinds@users.sourceforge.net>
-
-        * serial.c: (receive_char): Added counter to prevent infinite loop
-                when a PCMCIA serial device is ejected.
-
-Thu Dec 29 17:53:48 1994    <tytso@rsx-11.mit.edu>
-
-        * tty_io.c (check_tty_count): New procedure which checks
-                tty->count to make sure that it matches with the number of
-                open file descriptors which point at the structure.  If
-                the number doesn't match, it prints a warning message.
-
-Wed Dec 28 15:41:51 1994    <tytso@rsx-11.mit.edu>
-
-        * tty_io.c (do_tty_hangup, disassociate_ctty): At hangup time,
-                save the tty's current foreground process group in the
-                session leader's task structure.  When the session leader
-                terminates, send a SIGHUP, SIGCONT to that process group.
-                This is not required by POSIX, but it's not prohibited
-                either, and it appears to be the least intrusive way
-                to fix a problem that dialup servers have with
-                orphaned process groups caused by modem hangups.
-
-Thu Dec  8 14:52:11 1994    <tytso@rsx-11.mit.edu>
-
-        * serial.c (rs_ioctl): Don't allow most ioctl's if the serial port
-                isn't initialized.
-
-        * serial.c (rs_close): Don't clear the IER if the serial port
-                isn't initialized. 
-
-        * serial.c (block_til_ready): Don't try to block on the dialin
-                port if the serial port isn't initialized.
-
-Wed Dec  7 10:48:30 1994  Si Park (si@wimpol.demon.co.uk)
-        * tty_io.c (tty_register_driver): Fix bug when linking onto
-                the tty_drivers list. We now test that there are elements
-                already on the list before setting the back link from the
-                first element to the new driver.
-
-        * tty_io.c (tty_unregister_driver): Fix bug in unlinking the
-                specified driver from the tty_drivers list. We were not
-                setting the back link correctly. This used to result in
-                a dangling back link pointer and cause panics on the next
-                call to get_tty_driver().
-
-Tue Nov 29 10:21:09 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * tty_io.c (tty_unregister_driver): Fix bug in
-                tty_unregister_driver where the pointer to the refcount is
-                tested, instead of the refcount itself.  This caused
-                tty_unregister_driver to always return EBUSY.
-
-Sat Nov 26 11:59:24 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * tty_io.c (tty_ioctl): Add support for the new ioctl
-                TIOCTTYGSTRUCT, which allow a kernel debugging program
-                direct read access to the tty and tty_driver structures.
-
-Fri Nov 25 17:26:22 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * serial.c (rs_set_termios): Don't wake up processes blocked in
-                open when the CLOCAL flag changes, since a blocking
-                open only samples the CLOCAL flag once when it blocks,
-                and doesn't check it again.  (n.b.  FreeBSD has a
-                different behavior for blocking opens; it's not clear
-                whether Linux or FreeBSD's interpretation is correct.
-                POSIX doesn't give clear guidance on this issue, so
-                this may change in the future....)
-
-        * serial.c (block_til_ready): Use the correct termios structure to
-                check the CLOCAL flag.  If the cuaXX device is active,
-                then check the saved termios for the ttySXX device.
-                Otherwise, use the currently active termios structure.
-
-Sun Nov  6 21:05:44 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * serial.c (change_speed): Add support for direct access of
-                57,600 and 115,200 bps.
-
-Wed Nov  2 10:32:36 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * n_tty.c (n_tty_receive_room): Only allow excess characters
-                through if we are in ICANON mode *and* there are other no
-                pending lines in the buffer.  Otherwise cut and paste over
-                4k breaks.
-
-Sat Oct 29 18:17:34 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * serial.c (rs_ioctl, get_lsr_info): Added patch suggested by Arne
-                Riiber so that user mode programs can tell when the
-                transmitter shift register is empty.
-
-Thu Oct 27 23:14:29 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * tty_ioctl.c (wait_until_sent): Added debugging printk statements
-                (under the #ifdef TTY_DEBUG_WAIT_UNTIL_SENT)  
-
-        * serial.c (rs_interrupt, rs_interrupt_single, receive_chars,
-                change_speed, rs_close): rs_close now disables receiver
-                interrupts when closing the serial port.  This allows the
-                serial port to close quickly when Linux and a modem (or a
-                mouse) are engaged in an echo war; when closing the serial
-                port, we now first stop listening to incoming characters,
-                and *then* wait for the transmit buffer to drain.  
-
-                In order to make this change, the info->read_status_mask
-                is now used to control what bits of the line status
-                register are looked at in the interrupt routine in all
-                cases; previously it was only used in receive_chars to
-                select a few of the status bits.
-
-Mon Oct 24 23:36:21 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * serial.c (rs_close): Add a timeout to the transmitter flush
-                loop; this is just a sanity check in case we have flaky
-                (or non-existent-but-configured-by-the-user) hardware.

-        * tty_io.c (tty_fasync): When asynchronous I/O is enabled, if the
-                process or process group has not be specified yet, set it
-                to be the tty's process group, or if that is not yet set,
-                to the current process's pid.

-
-        * n_tty.c (n_tty_receive_room): If we are doing input
-                canonicalization, let as many characters through as
-                possible, so that the excess characters can be "beeped".
-
-Tue Oct 18 10:02:43 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * serial.c (rs_start): Removed an incorrect '!' that was
-                preventing transmit interrupts from being re-enabled in
-                rs_start().  Fortunately in most cases it would be
-                re-enabled elsewhere, but this still should be fixed
-                correctly.

-
-        * tty_io.c (do_tty_hangup): If the tty driver flags
-                TTY_DRIVER_RESET_TERMIOS is set, then reset the termios
-                settings back to the driver's initial configuration.  This
-                allows the termios settings to be reset even if a process
-                has hung up file descriptors keeping a pty's termios from
-                being freed and reset.
-
-        * tty_io.c (release_dev): Fix memory leak.  The pty's other
-                termios structure should also be freed.
-
-        * serial.c (rs_close, shutdown): Change how we wait for the
-                transmitter to completely drain before shutting down the
-                serial port.  We now do it by scheduling in another
-                process instead of busy looping with the interrupts turned
-                on.  This may eliminate some race condition problems that
-                some people seem to be reporting.
-
-Sun Sep 25 14:18:14 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * tty_io.c (release_dev): When freeing a tty make sure that both
-                the tty and the o_tty (if present) aren't a process's
-                controlling tty.  (Previously, we only checked the tty.)
-
-        * serial.c (change_speed): Only enable the Modem Status
-                Interrupt for a port if CLOCAL is not set or CRTSCTS
-                is set.  If we're not checking the carrier detect and
-                CTS line, there's no point in enabling the modem
-                status interrupt.  This will save spurious interrupts
-                from slowing down systems who have terminals that
-                don't support either line.  (Of course, if you want
-                only one of CD and CTS support, you will need a
-                properly wired serial cable.)
-
-Thu Sep 22 08:32:48 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * tty_io.c (do_SAK): Return if tty is null.
-
-        * tty_io.c (_tty_name): Return "NULL tty" if the passed in tty is
-                NULL.
-
-Sat Sep 17 13:19:25 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * tty_ioctl.c (n_tty_ioctl): Fix TIOCGLCKTRMIOS and
-                TIOCSLCKTRMIOS, which were totally broken.  Remove
-                extra indirection from argument; it should be a struct
-                termios *, not a struct termios **.
-                &real_tty->termios_locked should have been
-                real_tty->termios_locked.  This caused us to be
-                reading and writing the termios_locked structure to
-                random places in kernel memory.  
-
-        * tty_io.c (release_dev): Oops!  Forgot to delete a critical kfree
-                of the locked_termios.  This leaves the locked_termios
-                structure pointed at a freed object.  
-
-Fri Sep 16 08:13:25 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * tty_io.c (tty_open): Don't check for an exclusive open until
-                after the device specific open routine has been called.
-                Otherwise, the serial device ref counting will be screwed
-                up.
-
-        * serial.c (rs_open, block_til_ready): Don't set termios structure
-                until after block_til_ready has returned successfully.
-                Modify block_til_ready to check the normal_termios
-                structure directly, so it doesn't rely on termios being
-                set before it's called.
-
-Thu Sep 15 23:34:01 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-        * serial.c (rs_close): Turn off interrupts during rs_close() to
-                prevent a race condition with the hangup code (which
-                runs during a software interrupt).
-
-        * tty_io.c (release_dev): Don't free the locked_termios structure;
-                its state must be retained across device opens.
-
-
-        * tty_io.c (tty_unregister_driver): Added function to unregister a
-                tty driver.  (For loadable device drivers.)
