2003-10-03Merge tty_attach() in ttymalloc() and tty_detach() in ttyfree(). The need forMiod Vallat
separate tty registering is gone now that sparc has switched to wscons, and this makes the code less error-prone. Also, remove tests for ttymalloc() failure, since it uses M_WAITOK. ok millert@ deraadt@, tested by various people as well besides me...
2003-09-23Replace select backends with poll backends. selscan() and pollscan()Todd C. Miller
now call the poll backend. With this change we implement greater poll(2) functionality instead of emulating it via the select backend. Adapted from NetBSD and including some changes from FreeBSD. Tested by many, deraadt@ OK

2003-08-15change arguments to suser. suser now takes the process, and a flagsTed Unangst
argument. old cred only calls user suser_ucred. this will allow future work to more flexibly implement the idea of a root process. looks like something i saw in freebsd, but a little different. use of suser_ucred vs suser in file system code should be looked at again, for the moment semantics remain unchanged. review and input from art@ testing and further review miod@
2003-06-02Remove the advertising clause in the UCB license which BerkeleyTodd C. Miller
rescinded 22 July 1999. Proofed by myself and Theo.

Implemented with paranoia.

declarations (extern int foo), and compensate in the appropriate locations.

(Look ma, I might have broken the tree)
2001-10-07Setting the VTIME to a value larger than 214 lead to an integer overflowArtur Grabowski
in the calculation of the sleep timeout which could lead to a panic. Instead of doing the very error-prone, and in more than one way incorrect, sleep time calculation, allocate an external timeout and let it wake us. Reported by: Raan Young <raan@graand-visions.com>

2001-03-01port kqueue changes from freebsd, plus all required openbsd glue.Niels Provos
okay deraadt@, millert@ from jlemon@freebsd.org: extend kqueue down to the device layer, backwards compatible approach suggested by peter@freebsd.org
2000-07-19Many drivers use a timeout on ttrstrt, make this a generic interface.Artur Grabowski
2000-06-05Changes to exit handling.Artur Grabowski
cpu_exit no longer frees the vmspace and u-area. This is now handled by a separate kernel thread "reaper". This is to avoid sleeping locks in the critical path of cpu_exit where we're not allowed to sleep. From NetBSD
2000-03-23Iiieeek! This kludge was almost funny.Artur Grabowski
Probably something from the stone age. Kill it.

1997-10-21When the input queues are flushed on a blocked tty, make sure to unblockNiklas Hallqvist
it, if it's currently in a blocked state due to input flow control. This was typically seen with drivers implementing th t_hwiflow function, and starting of ppp (line discipline changes flushes the input queue). Independently discovered and fixed slightly different than NetBSD PR#4227.

1997-01-05Remove lots of timer_state structs as they just ate memory and only a few wasNiklas Hallqvist
ever used. Now a single state is kept for net, tty and disk events resp. Also, call the randomness from disk_unbusy instead of biodone, as biodone gets a lot of virtual events (from virtual filesystems etc), and as a bonus: feed xfer time and size into the entropy pool too.

1996-12-16Implement more tty flags for better portability from other systems:Thorsten Lockert
XCASE - canonical input/output processing IUCLC - translate uppercase to lowercase on input OLCUC - translate lowercase to uppercase on output OCRNL - translate carriage return to newline on output ONOCR - do not output carriage return at column 0 ONLRET - newline performs carriage return function In addition the tty compatibility interface supports LCASE properly. Look at termios(4) for a more complete description of the above flags.
