            Does anyone know of a patch that will add per jail memory
            limits so that a jail can't swallow the resources of the
            entire box?



        not yet..

    I started to port this to 7.1 today:


    What are the peoples opinions on this patch?


If you're soliciting opinions if this will be used and is needed, I would love to see this functionality. This is the main reason I've had to chose XEN over jails. If you need some help testing, let me know.

Hi Adam,

I have a patch against 7.1 here: http://svn.tomjudge.com/freebsd/patches/jail-resource-limits/jail-limits.patch

probably the person who should work with this in -current is james (CC'd)

Probably the person who should be contacted is trasz who worked on
hierachical resource limit per .., jail in p4.  Though this is
slightly different.

I think it's ok if people need those things to update the pathes but I
doubt any will probably ever make it into FreeBSD as those things are kind
of contrary to the V_ plans.

BTW, I think the patch referenced is not the latest I had seen and I
thought that we also had one for 7.x or even for 8 already floating around.
Maybe some investigation on list archives etc. might be helpful before
starting to hack things.  Maybe also check the links on

I will try to bring the patch up to current when I get a chance but I have no real need to do this as we use 7.1 in production.


* CPU limiting is not support is not supported unless you use shecd_4bsd. * I have not tested this on any system yet, just compile tested, I am putting it though its paces right now.
