Hello folks, Ever since rc.d was brought into the tree we all agreed IPv6 needed to be integrated better. Well, I've finally gotten arround to it... several years later :-P The patch is at: http://people.freebsd.org/~mtm/src-etc.ipv6.diff What it does ------------ - rc.d/network_ipv6 is no longer necessary and can be removed - IPv6 configuration is done on each interface in rc.d/netif along with IPv4 - IPv6 routing and options processing is done in rc.d/routing along with IPv4 - You can now do things like: # Start/Stop IPv6 on all interfaces /etc/rc.d/netif (start|stop) ip6 # Start/Stop IPv6 only on interface rl0 /etc/rc.d/netif (start|stop) rl0 ip6 # Do IPv6 options processing /etc/rc.d/routing options ip6 Overview of the changes in src/etc ----------------------------------- - In order to differentiate between v4 and v6 configuration directives some knobs in rc.conf(5)have been renamed with an ipv4_ prefix: network_interfaces ifconfig_DEFAULT ifconfig_<interface> ifconfig_<interface>_aliasX defaultrouter gateway_enable static_routes etc... - Modify all scripts that reference old knobs (without ipv4_ prefix) to reference the new version of the knobs - Compatibility shims in rc.subr(8) so that old uses of knobs without an ipv4_ prefix work as expected. As part of this change split the code for this processing into its own function: old2new_knobs() - Modify some routines in etc/network.subr to take an additional argument to specify v4 or v6 configuration: _ifconfig_get_args ifconfig_getargs autoif wpaif - Move some invocations of route(8) and v6 options processing into rc.d/routing I'm using the patches on my main work machine without any problems, so I think it's ready for a wider review. Please try it out and send me any comments, bug-reports, etc. I would especially like feedback from folks more familiar with IPv6. One gotcha I've noticed is that if you boot with ipv6_enable turned off, then try to start IPv6 on an interface later on, it doesn't work because none of the interfaces (except lo0) has a link-local address (see rc.d/auto_linklocal). How can we fix this? Also, I would appreciate feedback on how stopping IPv6 on an interface should be handled. In rc.d/network_ipv6 it was handled at all. Currently, it goes through and deletes all IPv6 addresses on the interface.
