Re: kernel/1816: Repetable crashes of ipfilter code

[Camiel Dobbelaar <dobbe@xs4all.nl>]

Another piece of the puzzle.

ipfilter is calling in_cksum(mbuf, hlen). Apparently the real length of
the mbuf is shorter then hlen. (ie. not enough data). 

in_cksum in OpenBSD is the only one that panics in that situation. FreeBSD
and NetBSD just put out a warning.
