Package: linux-2.6
Version: 2.6.32-30
Severity: important

When a process starts and ends inside a virtual server, virtual memory reported
by /proc/virtual/xxx/limit (as VM) decreases (at least by 1). The value drifts
slowly and reaches negative values.

As long as no hard/soft limit is set, this bug seems to have no incidence.
Otherwise, the virtual server become unusable when virtual memory reaches
negative values (memory allocation failures, new process get killed)

Someone reports the same issue on linux-vserver mailling list :
http://list.linux-vserver.org/archive?mss:4894:olhpkllgpffjhcfianop

After some tests and kernel rebuilds, it turns out that :
 - previous version (2.6.32-29) is not affected
 - drift does not occur when I exclude the patch debian/exec-Get-rid-of-
linux_binprm-vma_pages.patch

This patch is related to :
bugfix/all/exec-make-argv-envp-memory-visible-to-oom-killer.patch
bugfix/all/exec-copy-and-paste-the-fixes-into-compat_do_execve-paths.patch
