c7910c3ae3 Have this source explicitly include <sys/proc.h>, since it references
values such as P_CONTROLT and PS_INMEM.  But this still won't define
PID_MAX for us, since that is hidden inside of '#ifdef _KERNEL'.

5dfd7724a3 If <x> is a process id that does not exist, then just print the header
(if any) and exit, thus matching the behavior on -stable and other OS's.
My earlier attempt to fix this (v1.65) only seemed to work because of a
lucky random value in nentries (which was not being initialized back
when I tested that earlier patch).

e3c4e1dd77 If a non-existent user is given as part of `-U userlist', treat it as
a fatal error instead of a minor warning.  It is possible that a few
users are used to the previous behavior, but I'm claiming it was a bug.

a4c8a745a8 Support more POSIX/SUSv3 options:
- Change `-p' to allow a list of process IDs, and `-t' to allow a list
  of terminal names, instead of only a single value for each.
- Add the `-A' option of SUSv3, which is exactly the same as `-ax'.
- Add the `-G gidlist' (group id).
- Allow any of these "selector options" to be specified multiple times,
  and have `ps' keep adding to a given list -- instead of replacing the
  previously-specified values.
- Fix interactions between selector-options, so that: "If any are
  specified, ... ps shall select the processes represented by the
  inclusive OR of all the selection-criteria options." (from SUSv3)
- Add a `-X' option, which is the reverse of the `-x' option.

- various minor improvements in parsing and error handling.

This does not get us to match POSIX/SUSv3, but it gets us closer.  The
`-g pgidlist', `-R ruserlist' and `-s sidlist' options mentioned in
freebsd-standards are still under debate, so they skipped for now.
It should be true that this introduces no user-visible incompatible
changes, except to support "new stuff" that was not supported before.

just print the header (if any) and exit, thus matching the behavior on -stable

Also adds support for <x> being a comma-separated list of processes, and does

1f7d250182 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

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.

This fixes some nasty procfs problems for SMP, makes ps(1) run much faster,

bb22740673 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.)

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.
