CVS commit: src/sys/kern

[Matthias Drochner <drochner%netbsd.org@localhost>]

Module Name:    src
Committed By:   drochner
Date:           Wed Mar 15 16:12:07 UTC 2006

Modified Files:
        src/sys/kern: kern_sysctl.c

Log Message:
Check the "oldlen" argument to sysctl(2) before passing it
to vslock(9). This prevents a local DOS.
(The checks against system and user limits for wired
memory should be centralized in UVM; for now prefer a less
invasive fix which can be pulled pulled up into releases.)
