* Fix line discipline switching issues: If opening a new ldisc fails,Poul-Henning Kamp2004-06-261-10/+2
| | | | | | | | | | | | | | | | we have to revert to TTYDISC which we know will successfully open rather than try the previous ldisc which might also fail to open. Do not let ldisc implementations muck about with ->t_line, and remove code which checks for reopens, it should never happen. Move ldisc->l_hotchar to tty->t_hotchar and have ldisc implementation initialize it in their open routines. Reset to zero when we enter TTYDISC. ("no" should really be -1 since zero could be a valid hotchar for certain old european mainframe protocols.) Notes: svn path=/head/; revision=131130

* Change the suser() API to take advantage of td_ucred as well as do aJohn Baldwin2002-04-011-4/+4
| | | | | | | | | | | | | | | 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.

* * Rename M_WAIT mbuf subsystem flag to M_TRYWAIT.Bosko Milekic2000-12-211-1/+1
| | | | | | | | | | | | | | | | | | | | | This is because calls with M_WAIT (now M_TRYWAIT) may not wait forever when nothing is available for allocation, and may end up returning NULL. Hopefully we now communicate more of the right thing to developers and make it very clear that it's necessary to check whether calls with M_(TRY)WAIT also resulted in a failed allocation. M_TRYWAIT basically means "try harder, block if necessary, but don't necessarily wait forever." The time spent blocking is tunable with the kern.ipc.mbuf_wait sysctl. M_WAIT is now deprecated but still defined for the next little while. * Fix a typo in a comment in mbuf.h * Fix some code that was actually passing the mbuf subsystem's M_WAIT to malloc(). Made it pass M_WAITOK instead. If we were ever to redefine the value of the M_WAIT flag, this could have became a big problem. Notes: svn path=/head/; revision=70254

* Undo #undef KERNEL hack for vnode.h to avoid vnode_if.h.Peter Wemm1999-01-171-9/+2
| | | | | | | | | | | | XXX It probably makes sense to have a flag for bsd.kern.mk to avoid these rules. XXX IO_NDELAY seems to be the main reason for it, when used in a cdevsw read or write "flag" context.

* Eradicate the variable "time" from the kernel, using various measures.Poul-Henning Kamp1998-03-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "time" wasn't a atomic variable, so splfoo() protection were needed around any access to it, unless you just wanted the seconds part. Most uses of time.tv_sec now uses the new variable time_second instead. gettime() changed to getmicrotime(0. Remove a couple of unneeded splfoo() protections, the new getmicrotime() is atomic, (until Bruce sets a breakpoint in it). A couple of places needed random data, so use read_random() instead of mucking about with time which isn't random. Add a new nfs_curusec() function. Mark a couple of bogosities involving the now disappeard time variable. Update ffs_update() to avoid the weird "== &time" checks, by fixing the one remaining call that passwd &time as args. Change profiling in ncr.c to use ticks instead of time. Resolution is the same. Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call hzto() which subtracts time" sequences.

* Don't test for conflicting combinations of PPP_FILTER/BPFILTER here.Bruce Evans1997-11-181-29/+9
| | | | | | | | | | | | | | | | | Testing in if_ppp.c is good enough. Added comments about bogus #includes and #defines. Removed unused #includes. Don't depend on gcc's misfeature of rewriting short args in old-style function definitions to match wrong prototypes. I just changed the function definition to match the prototype, since this is easy to verify automatically (it causes no changes in the object code), but it breaks K&R1 support and doesn't fix the pessimal type.

It seems that the lkm system doesn't particularly like having two sets of load/unload/etc routines. :-] This really should be fixed by having a seperate if_ppp and ppp_tty lkm, but that requires that ppp_tty is loaded after if_ppp, and needs to be able to link with symbols in if_ppp. This gets messy, it is a better task for the in-kernel linker.
