* MFC *: Fix the kludge-old-options processing so `ps tpt' will be treatedGarance A Drosehn2004-06-081-107/+126
| | | | | | | | | | | | | | | | | | | | | the same as `ps -tpt', instead of being changed into `ps -tpT'. Also adjust it so `ps t p0' is treated like `ps -t p0', instead of making it `ps -T p0'. This includes the rewrite of the kludge-option processing, but it does NOT remove the long-undocumented BACKWARD_COMPATIBILITY compile-time option. If you delete the '#define BACKWARD_COMPATIBILITY' line, you'll get the newer handling for "extra arguments", which is to treat them as requests for processes. Also brings in a number of style(9) improvements.

* MFC *: Support more POSIX/SUSv3 options:Garance A Drosehn2004-04-043-212/+665
| | | | | | | | | | | | | | | | | | | | | | | | | | - 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 should result in no user-visible changes, except for adding the new features. The man page is updated to describe the new features, and to describe the sorting options in better and more complete detail.

* I'm probably jumping the gun, but what the heck, this is -current.Peter Wemm1999-11-171-2/+2
| | | | | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=53278

* Introduce commandline caching in the kernel.Poul-Henning Kamp1999-11-161-1/+1
| | | | | | | | | | | | | | 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 For full details see the current@FreeBSD.org mail-archives. Notes: svn path=/head/; revision=53239

* This Implements the mumbled about "Jail" feature.Poul-Henning Kamp1999-04-282-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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...

* On FreeBSD/alpha, ps(1) does not correctly report process start timesBill Paul1999-04-011-1/+40
| | | | | | | | | | | | | | | | | | | | 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.)
