Bug#677738: kfreebsd-8: Reference count errors in IPv6 code
Tags: patch squeeze
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.
