412d4e7d1b Use correct basic types when addresses are given in function calls. 2003-09-03 11:36:52 +00:00

2768d776d4 Use pfind() in proc_sysctl() to find the target process instead of a 
home-grown routine.  Remove defcorenamelen, since it's not used
anywhere.

hardcoding its size.

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

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

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

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.

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.

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".

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.

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''.

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

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.

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.

OS name, hw name, kernel version, and so forth.

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...
