Hi,
After r188146 creating tcp ipv6 socket in jail without ipv6 ip is not
allowed, but udp socket is allowed.
I cannot really follow what you are trying to say as wrt IPv4 and IPv6
sockets and what about UDP.
Your sample further down is trying to use an IPv4 address on an IPv6
Datagram socket which is an error either way.
Some java programms attempt to use ipv6 sockets, then use ipv4 if
socket(AF_INET6,...) fail. My sample imitate this
Prior to FreeBSD 7.2 IPv6 hadn't been supported at all for jails.
With 7.2 it was possible to create IPv6 sockets (but only shortly and
then fail on bind/connect/...). With the commit you reference the
"Protocol not supported" came back in case there was no address of
that address family for a given jail.
With 8 the primary syntax for jails has changed and the "backward
compat mode" again allows you to create a socket on a jail even if
no address of the same family was configured for the jail.
This should be addressed by the following patch:
http://people.freebsd.org/~bz/20090727-01-jail8-legacy.diff
Can you give it a try and report if that fixes your problem?
Patch aplied cleanly on r195820 , but jail can not start after patching:
# jail -l -U root -i /usr/home/d/guests/tap2 tap2.my.domain.com 10.112.0.151
/bin/sh /etc/rc
jail: ip6: unknown boolean value "disable"
r195820 is too old; but Jamie has a better solution; I would suggest
to backout the jail(8) patch and wait for the next two commits of
Jamie to HEAD and then update the machine again.
