c1f79de8c7 Use the MAC interface to list process MAC labels rather than using
the LOMAC-specific interface (which is being deprecated).  The
revised LOMAC using the MAC framework will export levels listable
using this mechanism.

84d13cfde4 Oops, the previous version was a last minute test version with off_t
replaced by int instead of size_t.

6e48538b41 Use a non-bogus type for representing the values of offsets in structs.
off_t is for offsets in files, and it is signed so it was no better
than the original type of int for avoiding warnings from broken lints,
except accidentally on machines like i386's where size_t is smaller
than off_t.

b561096e47 Conglomerate printing of ps_pgtok'd data into a PLONG type. I couldn't think
of a better name, except PINT, but I decided to go with assuming LONG to
be safe, rather than assuming INT.

fece93f6bd Perform keyword.c:1.27 properly, implement -orss in the New World Order of
ps(1) formatting, using pgtok() to get the value in K, rather than printing
it in pages.  This is consistent with behaviour before keyword.c:1.26 (et al)
which exists in STABLE today, and which uses the same metric as VSZ.

f340aa750e Fixed a printf format error that was fatal on alphas. Adding WFORMAT=0
to the Makefile didn't affect this bug because WFORMAT only controls
higher- level format checking (not the -Wformat that is implicit in
-Wall).

Fixed a nearby printf format error that was benign and 3 nearby style bugs.

8e683e45ef Don't try to decode old-style options if the argv[1] begins with `-' and the
second character represents some option taking an argument. This fixes
problem when ps(1) is invoked for examply as follows:

$ ps -Ufoobar1234

the above example results in option string being interpreted as
-U foobarp1234 - note extra `p'.

cba301121b Change the proc information returned from the kernel so that it
no longer contains kernel specific data structures, but rather
only scalar values and structures that are already part of the
kernel/user interface, specifically rusage and rtprio. It no
longer contains proc, session, pcred, ucred, procsig, vmspace,
pstats, mtx, sigiolst, klist, callout, pasleep, or mdproc. If
any of these changed in size, ps, w, fstat, gcore, systat, and
top would all stop working. The new structure has over 200 bytes
of unassigned space for future values to be added, yet is nearly
100 bytes smaller per entry than the structure that it replaced.

769e0f974d Major update to the way synchronization is done in the kernel. Highlights
include:

* Mutual exclusion is used instead of spl*().  See mutex(9).  (Note: The
  alpha port is still in transition and currently uses both.)

* Per-CPU idle processes.

* Interrupts are run in their own separate kernel threads and can be
  preempted (i386 only).

f6968a45e6 I'm probably jumping the gun, but what the heck, this is -current.
Turn off setgid-kmem for /bin/ps, it's now quite functional without it.
ps no longer needs /dev/*mem or /proc.  (It will still use some /proc
files if they are available for -e, but it's not required, so it'll
happily run in a jail or chroot).

The proc stats are now part of eproc (obtained via sysctl) and no longer
needs to beat up the u-page reading code and the problems with that.

This also has the side effect of disabling 'ps -e' for normal users
*EXCEPT* when looking at their own processes.  ie: they can see
environments in processes with their uid, enforced by the ownership of
/proc/*/mem.  Root can still see them all, as it can open all /proc/*/mem.

cc6b664e2e Introduce commandline caching in the kernel.
This fixes some nasty procfs problems for SMP, makes ps(1) run much faster,
and makes ps(1) even less dependent on /proc which will aid chroot and
jails alike.

To disable this facility and revert to previous behaviour:
        sysctl -w kern.ps_arg_cache_limit=0

ca21a25f17 This Implements the mumbled about "Jail" feature.
This is a seriously beefed up chroot kind of thing.  The process
is jailed along the same lines as a chroot does it, but with
additional tough restrictions imposed on what the superuser can do.

For all I know, it is safe to hand over the root bit inside a
prison to the customer living in that prison, this is what
it was developed for in fact:  "real virtual servers".

Each prison has an ip number associated with it, which all IP
communications will be coerced to use and each prison has its own
hostname.

Needless to say, you need more RAM this way, but the advantage is
that each customer can run their own particular version of apache
and not stomp on the toes of their neighbors.

It generally does what one would expect, but setting up a jail
still takes a little knowledge.

A few notes:

   I have no scripts for setting up a jail, don't ask me for them.

   The IP number should be an alias on one of the interfaces.

   mount a /proc in each jail, it will make ps more useable.

   /proc/<pid>/status tells the hostname of the prison for
   jailed processes.

   Quotas are only sensible if you have a mountpoint per prison.

   There are no privisions for stopping resource-hogging.

   Some "#ifdef INET" and similar may be missing (send patches!)

If somebody wants to take it from here and develop it into
more of a "virtual machine" they should be most welcome!

Tools, comments, patches & documentation most welcome.

Have fun...

9bde04a698 On FreeBSD/alpha, ps(1) does not correctly report process start times
and CPU runtime because it can't access the user area via /proc/<pid>/mem.
This is because the uarea is not mapped into the process address space
at USRSTACK on the alpha like it is on the x86.

Since I'm haven't been able to wrap my brain around the VM system enough
to be able to figure out how to achieve this mapping, and since it's
questionable that such an architectural change is correct, I implemented
a workaround to allow ps(1) to read the uarea from /dev/kmem using
kvm_read() instead of from the process address space via kvm_uread().
The kludge is hidden inside #ifdef __alpha__/#endif so as not to impact
the x86. (Note that top(1) probably uses this same gimmick since it works
on FreeBSD/alpha.)

Maintain process "on-cpu" time as 64 bits of microseconds to avoid

Avoid calling microuptime the second time in mi_switch() if we do
not pass through _idle in cpu_switch()

This should reduce our context-switch overhead a bit, in particular
on pre-P5 and SMP systems.

for users who are root, or in group wheel.  This is useful on large timesharing
systems where a PS command can cause the system to grind to a halt.  The
ability to get the information isn't diminished for those who really need the
additional detail (administrators.)  Normal users won't see any difference unless
the processes are swapped out.  The "really get it mode" is invoked by the
use of an additional flag in the command string "-f".  New/old behavior is
selectable with a compile option.
