sysctl. Add a protocol-independent sysctl handler to show the per-protocol

Other protocols can show their per-protocol input statistics by
allocating a sysclt node and calling sysctl_ifq() with their own struct ifq *.

lukem ea56af7b9d Tweak behaviour introduced in rev 1.50; 
*	by default, warning messages go to stderr
    *	if -A or -a is used, send warning messages to stdout instead.

The behaviour in 1.50 meant that
	somevar=`sysctl -n machdep.booted_kernel 2>/dev/null`
could end up with $somevar="machdep.booted_kernel: the value is not available"
rather than the more useful $somevar="".

(This way, "sysctl -A | grep ..." is still useful.)

manu 41bfbd28fe On Darwin, mach_init is the system bootstrap process. It is responsible 
for forking the traditional UNIX init(8) and it does the Mach port naming
service. We need mach_init for the naming service, but unfortunately, it
will only act as such if its PID is 1. We introduce a sysctl
(emul.darwin.init_pid) to fool a given process into thinking its PID is 1.
That way we can get mach_init into behaving as the name server.

Typical use:
/sbin/sysctl -w emul.darwin.init_pid=$$ ; exec /emul/darwin/sbin/mach_init
 2002-12-24 12:15:45 +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.
 2002-12-11 19:14:34 +00:00
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 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...

jdolecek 0fe5bf8257 pipe sysctl stuff is now in <sys/pipe.h> 2001-07-02 20:55:16 +00:00
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.
