thorpej f10e7dc65b Don't reset file size limit to infinity on exit. Instead, temporarily
raise the limit to infinity when writing out the accounting file.

itojun e6469f14ad move static function getstr() to cons.c, make it publically available
as cngetsn().  there will be other consumer.

sommerfeld 4d573016ed Let MULTIPROCESSOR && LOCKDEBUG case compile again 2000-05-03 13:53:59 +00:00
pk 716a862d08 Lock internals have changed, and we depend on those in here. 2000-05-02 09:29:39 +00:00
thorpej 8185691694 - If a platform defines __HAVE_ATOMIC_OPERATIONS, use them for counting
in the MULTIPROCESSOR case.
- Move a misplaced #ifdef so that LK_REENABLE actually works.

thorpej f51470a514 Require that each each MACHINE/MACHINE_ARCH supply a lock.h. This file
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED.  These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case).  Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.

These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.

minoura f6051edef5 Add native issetugid() call.
Implementation from compat/freebsd.

thorpej c6fa58a322 - Allocate the ktrace operation header on the stack rather than using
MALLOC()/FREE().
- In ktrgenio():
	- Don't allocate the entire size of the I/O for the temporary
	  buffer used to write the data to the trace file.  Instead,
	  do it in page-sized chunks.
	- As in uiomove(), preempt the process if we are hogging the CPU.
	- If writing to the trace file errors, abort rather than continuing
	  to loop through the buffer.

From Artur Grabowski <art@stacken.kth.se>, with some additional cleanup
by me.

mrg 9dc12ba15b regen 2000-04-17 14:33:11 +00:00
mrg a6f7a7855f implement lchflags(2), which does the chflags(2) dance without following
symlinks, and thus can operate on symlinks.  remove a bogus comment in
chflags(1) that claims symlinks do not have file flags.

XXX: todo -- make chflags(1) use lchflags(2) when given the right options.

chs 9431f1857b change "nextvnodeid" from a global in namei.h to a static in
the one function that uses it.
2000-04-16 21:41:49 +00:00
chs d0fb21715e limit the number of namecache entries to numvnodes rather than desiredvnodes.
getnewvnode() has been changed to virtually guarantee that we'll have more
vnodes than "desired", so previously there would always be more vnodes
than namecache entries.  this fixes PR 9792.

simonb dd06794f0b Remove shmsegs declaration from conf/param.c - it doesn't belong here.
Instead, put it in kern/sysv_shm.c.
2000-04-15 16:49:35 +00:00
simonb 55bf62c1a1 For the KERN_PROC sysctl, when using KERN_PROC_TTY allow
KERN_PROC_TTY_NODEV to select processes with no controlling
tty and KERN_PROC_TTY_REVOKE to select processes with a
revoked controlling tty.
2000-04-15 04:38:07 +00:00
chs c81c7aa367 always define PI_MAGIC so this compiles in all cases. 2000-04-13 00:44:19 +00:00
simonb 6008cfd5de Remove bogus "#ifdef EIDRM" checks and warnings that BSD doesn't define
EIDRM - EIDRM was added over two years ago!
2000-04-12 13:08:26 +00:00
fvdl ea3e5a38b8 Fix from Ethan Solomita <ethan@geocast.com> to avoid a livelock problem
where the buffer cache code would be recycling B_AGE buffers with
dependencies.
2000-04-12 11:33:43 +00:00
chs a6d33cc1f2 add a new function vn_marktext() for exec code to let others know
that the vnode is now being used as process text.
2000-04-11 04:37:47 +00:00
chs 1c084aee4f add ddb commands for printing vnodes and bufs. 2000-04-10 02:22:13 +00:00
chs 9faf1824c8 in pool_put(), fill the entire object with PI_MAGIC instead of just the
first element.

augustss c87c1861bb Add a special option, DEBUG_HALT_BUSY, that allows you to debug when the
system doesn't want to halt cleanly.  The code was there before, but only
with the DEBUG option.
2000-03-30 09:32:25 +00:00
augustss 264f1d27c6 Get rid of register declarations. 2000-03-30 09:27:11 +00:00
simonb 6fa443065b Delete redundant decl of union_vnodeop_p, it's in <miscfs/union/union.h>. 2000-03-30 02:15:09 +00:00
simonb d1f05e517a Delete redundant decl of dounmount(), it's in <sys/mount.h>. 2000-03-30 02:12:25 +00:00
simonb 9ff7681a33 Don't need to include <sys/conf.h> here. 2000-03-29 03:43:31 +00:00
simonb 6043a575b2 Remove declaration of db_radix - <ddb/db_output.h> has one.
Also remove <sys/conf.h> - don't need it here.
2000-03-29 03:05:18 +00:00
simonb 2f1fef39b3 Centralise the declarations of cpu_model, machine, machine_arch,
osrelease, and ostype and remove "extern char foo[];" (for hostname
and domainname too).

Also delete redunctant decl of boottime in kern_info_43.c.
2000-03-28 23:57:24 +00:00
simonb bb1fc886cf endtsleep() is prototyped at the top of the file, delete duplicate
declaration inside tsleep().
2000-03-28 22:04:46 +00:00
simonb 468456cf00 Delete duplicate definition of kernel time variable (in <sys/kernel.h>). 2000-03-28 22:01:52 +00:00
kleink 2e68f6172e Cast timeval members to types we know the printf conversions of. 2000-03-28 18:39:03 +00:00
augustss 61462c55a3 Get rid of a lot of register declarations.
(Why isn't this done everywhere in the kernel already?)
2000-03-28 17:30:10 +00:00
simonb 071bde5df6 Don't need to declare nblkdev, nchrdev - these are in <sys/systm.h>. 2000-03-28 06:26:22 +00:00
kleink 230876cf26 Merge parts of chs-ubc2 into the trunk:
* Remove the casts to vaddr_t from the round_page() and trunc_page() macros to
  make them type-generic, which is necessary i.e. to operate on file offsets
  without truncating them.
* In due course, cast pointer arguments to these macros to an appropriate
  integral type (paddr_t, vaddr_t).

Originally done by Chuck Silvers, updated by myself.

enami f9c7a69ff5 Call the routine to calculate callwheelsize from allocsys() instead of
main() since some port like alpha and mips calls allocsys() before main()
is called.  While I'm here, I renamed some function.
2000-03-24 11:57:14 +00:00
thorpej 2b58edac40 Remove the CALLWHEEL_SORT code. It was implemented just for experimenting,
and I had no plans to ever enable it.  A record of the code is now in the
CVS history of the file, so we can unclutter now.
2000-03-23 20:51:09 +00:00
thorpej 7c8b72d592 uiomove(): if we're informed that we should yield the CPU, use the new
preempt() primitive to do so.
2000-03-23 20:39:58 +00:00
thorpej 68054a285a Track if a process has been through a round-robin cycle without yielding
the CPU, and mark that it should yield if that happens.

Based on a discussion with Artur Grabowski.

soren 93c531f872 Tiny comment update. 2000-03-23 14:32:41 +00:00
thorpej b667a5a357 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.
