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.

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.

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.

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. - -Fri Oct 21 09:37:23 1994 Theodore Y. Ts'o (tytso@rt-11) - - * 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. - -Thu Oct 20 23:17:28 1994 Theodore Y. Ts'o (tytso@rt-11) - - * 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. - -Sun Oct 9 23:46:03 1994 Theodore Y. Ts'o (tytso@rt-11) - - * 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.
