Hello,
I've put an updated version of user beancounter patch intended to provide
advanced resource control and protection against local denial-of-service
attacks.
It contains just some bugfixes, namely:
- incorrect memory accounting for CLONE_VM-cloned tasks;
- a small mistake in RSS accounting;
- mremap() memory accounting leak;
- cosmetic fix for always-false `if' statement;
- Configure.help correction (thanks to Keith Owens <kaos@ocs.com.au>
reporting the inaccuracy).
At this moment I'm investigating how different modifications of swap-out
algorithm providing RSS guarantees behave under different types of load.
Patch web page is

the patch itself

The small program for patch testing
http://www.asplinux.com.sg/install/ulim4.c
accidently disappeared from the site, I've put it back.
Sorry to those who tried to get it, and thanks to Marcelo Tosatti for the
notice.
Best regards
Andrey V.
