clean structures before reusing
Let's try this in a shell:
# n=32
# for i in $(jot $n 1); do
> ipfw -q add 1 count ip from any to any
> ipfw -q add 2 count ip from any to any
> done
# ipfw delete 1 2
ipfw: rule 2: setsockopt(IP_FW_XDEL): Invalid argument
Rules numbered 1 got deleted, rules numbered 2 do not.
Note that problem does not manifest if n<32.
A bug is in /sbin/ipfw's ipfw_delete() function that fails to clean "rt"
structure before each iteration. ipfw_zero() function has similar problem.
Attached patch fixes this.
