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...

Initialize lcap and pwd to NULL. This allows a WARNS=6 clean build, hence bump it to 6. Note that the last commit message was not quite accurate. While the assumption exists in the code, it's not possible to have an uninitialized p there because if lflag is set when username is NULL then execution would be terminated earlier. 2004-11-17 10:01:48 +00:00			`WARNS?= 6`
Perform a major cleanup of the usr.sbin Makefiles. These are not perfectly in agreement with each other style-wise, but they are orders of orders of magnitude more consistent style-wise than before. 2001-07-20 06:20:32 +00:00
