Description Bjoern A. Zeeb freebsd_committer

Debugging 203735 I noticed the following behaviour:

root@:/ # ipfw show
65535 0 0 allow ip from any to any

root@:/ # ipfw add 1 allow ip from 'table(99)' to me
00001 allow ip from table(99) to me

root@:/ # ipfw show
Segmentation fault (core dumped)


Can someone please have a look.  In my case this is with a VIMAGE kernel but that shouldn't matter on the user space binary.

Seems to be related after all;  once I start the first vnet jail ipfw show dumps core even in the base system.  Anyone any ideas?

Should be fixed in r306475.
