3d0d5dccc1 Cast arg_max to size_t when comparing it (times 4, plus 1) against SIZE_MAX. I
was worried about truncation of arg_max by this cast, but if it gets truncated,
we know it'll obviously be greater than SIZE_MAX anyway.

40fea9c3a5 As per behaviour on SVR4 systems, to allow any desirable type of header in the
override, seperate by comma (',') only, rather than any type of whitespace
(the literal space character (' ') had already been removed from this list).

This allows things like:
miamivice# ps -opid='Process
> Identifier'
Process
Identifier
              1350
              1445

634d96e194 Check for possible overflow from sysconf _SC_ARG_MAX and error out in a
correct manner.  Revert my incorrect change to use err(3) for malloc(3)
failing.  Use a size_t variable to store the size of the argument buffer
we allocate, and remove silly casts as the result of having this around.
Modify the math in some of the paranoid checks for buffer overflow to
account for the fact we now are dealing with the actual size of the
buffer.  Remove the static qualifier for arg_max, and the bogus setting
of it to -1.

Include <limits.h> for the definitions we use to check for possible
overflows.

* Per-CPU idle processes.

* Interrupts are run in their own separate kernel threads and can be

821079e9be 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.

b9df5231ca 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

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...

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.)
