Subject: kfreebsd-8: Reference count errors in IPv6 code
Date: Sat, 16 Jun 2012 16:36:20 +0100
Package: src:kfreebsd-8
Version: 8.1+dfsg-8+squeeze2
Severity: important
Tags: patch squeeze
Usertags: kfreebsd


Errata notice FreeBSD-EN-12:02.ipv6refcount affects the kfreebsd-8
package in squeeze.
> Under high IPv6 network load, reference counts may improperly hit zero
> due to overflow or underflow, causing an IPv6 address, which is still in
> use, to be freed.  This will lead to a kernel panic on next access.

Please apply the patch from the erratum.
