* Pick the hotchar out of the tty structure instead of caching privatephk2004-06-262-3/+2
| | | | | | | | copies. No current line disciplines have a dynamically changing hotchar, and expecting to receive anything sensible during a change in ldisc is insane so no locking of the hotchar field is necessary.

* Device megapatch 4/6:phk2004-02-211-1/+2
| | | | | | | | Introduce d_version field in struct cdevsw, this must always be initialized to D_VERSION. Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.
* Device megapatch 3/6:phk2004-02-211-3/+0
| | | | | | | | | | | | Add missing D_TTY flags to various drivers. Complete asserts that dev_t's passed to ttyread(), ttywrite(), ttypoll() and ttykqwrite() have (d_flags & D_TTY) and a struct tty pointer. Make ttyread(), ttywrite(), ttypoll() and ttykqwrite() the default cdevsw methods for D_TTY drivers and remove the explicit initializations in various drivers cdevsw structures.

This patch is automatically generated and has been tested by compiling LINT with all the fields in struct cdevsw in reverse order on alpha, sparc64 and i386. Approved by: re(scottl)

* Change the suser() API to take advantage of td_ucred as well as do ajhb2002-04-011-5/+5
| | | | | | | | | | | | general cleanup of the API. The entire API now consists of two functions similar to the pre-KSE API. The suser() function takes a thread pointer as its only argument. The td_ucred member of this thread must be valid so the only valid thread pointers are curthread and a few kernel threads such as thread0. The suser_cred() function takes a pointer to a struct ucred as its first argument and an integer flag as its second argument. The flag is currently only used for the PRISON_ROOT flag.

| | | | | | | | | | | | | | | | | does ignore DCD. Even TIOCMGET cannot read DCD as the firmware doesn't report it. This has pretty interesting effects for ppp(8) which runs in clocal mode and polls carrier (!). (Specialix's linux driver does this too) Also update the firmware to 3.0.6 for the SX cards, as apparently there was a problem with floating (disconnected) DCD pins causing stray carrier transitions, especially at port open time. It seems to work here, and carrier loss is detected nearly immediately rather than having to wait for a LQR timeout (a few minutes) before ppp(8) gives up. DCD problem noted by: nsayer
