fvdl d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.

enami e946a4baa0 Adjust !LKM case for proc * -> lwp * change. 2003-06-29 02:23:19 +00:00
darrenr 960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

martin d505b18964 Make sure to include opt_foo.h if a defflag option FOO is used. 2003-06-23 11:00:59 +00:00
jdolecek 5fe02453b5 put back nmaxproc check mistakely changed in rev.1.132
checking against nprocs is wrong in any case btw - we do allow
maxproc higher than number of current processes, it would just mean
no new process could be started until number of processes would
be lower than the new limit

dsl 9be8ac5294 Alternative pid/proc allocater, removes all searches associated with pid
lookup and allocation, and any dependency on NPROC or MAXUSERS.
NO_PID changed to -1 (and renamed NO_PGID) to remove artificial limit
on PID_MAX.
As discussed on tech-kern.

thorpej 9e7bb2595e Based on the feedback on wasabisystems.com!bsd-api-discuss (sure wish
people would read that list in a more timely fashion!), change the new
64-bit memory reporting sysctl nodes to report bytes.  This should not
be a problem, since it's only a week old, and no applications use the
new nodes yet.

atatat 40f3045957 Add p_svuid and p_svgid to kinfo_proc2. Populate them in the kernel
and in libkvm.  Then teach ps how to show them to you.

Also, teach ps how to show the names for all the uids, the rest of the
group numbers, and the "group access list".
2003-03-01 05:41:55 +00:00
thorpej 922f0e9b78 Add hw.physpages and hw.userpages, which return the physmem and usermem
values as a u_quad (page count).  Necessary for reporting memory on systems
with >=4G.  Per disussion on wasabisystems.com!bsd-api-discuss.
2003-02-27 01:39:56 +00:00
dsl 9926e89884 Fix support for 16 character lognames
(approved by christos)
2003-02-15 18:47:41 +00:00
atatat a8481319cb Add a kern.dump_on_panic sysctl variable (and documentation, and a
kernel config option) that controls whether the kernel dumps to the
dump device on panic.  Dumps can still be forced via the ``sync''
command from ddb.  Defaults to ``on''.

jdolecek 94062cc04a add support for optional arch-specific restriction of valid value
for kern.maxproc
2002-12-16 18:15:18 +00:00
jdolecek 300acddf8c don't allow kern.maxproc bigger than PID_MAX - PID_SKIP; the pid allocation
code in fork1() would enter endless loop if all the allowed pids are taken
by running processes
2002-12-12 20:54:58 +00:00
jdolecek 5fd22809a5 Add kern.forkfsleep sysctl - set/get time (in miliseconds) for which
process would be forced to sleep in fork() if it hits either global
or user maxproc limit. Default is zero (no forced sleep).
Maximum is 20 seconds.

scw 39a5a9dc76 Add two sysctls: kern.labelsector and kern.labeloffset.
These are of use to userland code which previously depended on the
hard-coded values of LABELSECTOR and LABELOFFSET to figure out the
location of the disklabel for a particular platform.

With the introduction of umbrella ports such as evbarm, evbmips, etc,
the location of the disklabel may vary between kernels for the same
MACHINE. This sysctl will allow userland programs to remain independent
of the particular flavour of MACHINE in such cases.

manu 99bc517790 Added sysctl to change all IRIX kernel values reported by uname and systeminfo:
OS name, hw name, kernel version, and so forth.
2002-11-09 09:03:56 +00:00
manu 9a4dfe85fa Added two sysctl-able flags: proc.curproc.stopfork and proc.curproc.stopexec
that can be used to block a process after fork(2) or exec(2) calls. The
new process is created in the SSTOP state and is never scheduled for running.

This feature is designed so that it is esay to attach the process using gdb
before it has done anything.

It works also with sproc, kthread_create, clone...

augustss 731d1eccf2 Get rid of sysctl for setting BCM2033 firmware path. It doesn't work
for ports that don't include files.usb, and it's also not done quite
the way it should.

path for my BCM2033).

lukem fea75ff830 - kern.maxvnodes: only call vfs_reinit() and nchreinit() if the value
was successfully changed.  previously, successfully viewing the
  current value would flush the cache :-/
- similarly, don't change hostid and sb_max unless the value was
  successfully changed

chs 7bb91a0959 resize the namecache hash table also when desiredvnodes changes. 2001-09-24 06:01:13 +00:00
chs adf5d360a7 add a new VFS op, vfs_reinit, which is called when desiredvnodes is
adjusted via sysctl.  file systems that have hash tables which are
sized based on the value of this variable now resize those hash tables
using the new value.  the max number of FFS softdeps is also recalculated.

convert various file systems to use the <sys/queue.h> macros for
their hash tables.

jdolecek ee882e3a09 Add port of high performance pipe implementation written by John S. Dyson
for FreeBSD project. Besides huge speed boost compared with socketpair-based
pipes, this implementation also uses pagable kernel memory instead of mbufs.

Significant differences to FreeBSD version:
* uses uvm_loan() facility for direct write
* async/SIGIO handling correct also for sync writer, async reader
* limits settable via sysctl, amountpipekva and nbigpipes available via sysctl
* pipes are unidirectional - this is enforced on file descriptor level
	for now only, the code would be updated to take advantage of it
	eventually
* uses lockmgr(9)-based locks instead of home brew variant
* scatter-gather write is handled correctly for direct write case, data
  is transferred by PIPE_DIRECT_CHUNK bytes maximum, to avoid running out of kva

All FreeBSD/NetBSD specific code is within appropriate #ifdef, in preparation
to feed changes back to FreeBSD tree.

This pipe implementation is optional for now, add 'options NEW_PIPE'
to your kernel config to use it.

enami 5a6a17f734 Make sysctl_msgbuf() to copy message buffer to userland even if
