RELENG_5 and carp patches - Status

[Bruno Afonso]

I've forgotten to say one thing. I had to add the carp definition to
/etc/protocols. In reality, I renamed "vrrp" to "carp" after looking at
openbsd's /etc/protocols. So, it's missing in the patch too.

Seems to apply cleanly. You have to cd /usr/src/sbin/ifconfig before
"patch -p0 < " though.
I can now do "ifconfig pfsync0 up syncif <interface>" without any error.

Doh! Damn home made script to generate the pf conf file... :-)
I needed to open carp0 from (carp0) to (carp0). Another interesting
aspect is that traffic originating from the machine come from the
non-carp ips. :-)

Ye, doesn't bother.

Did it. Same error(s). I'm gonna recompile world and kernel just for the
sake of it. :-) and rm -rf /usr/obj.
