init.c: init & setup IPv6 route list & add/delete IPv6 routes + - tun.c: add "ifconfig" and "route" handling for IPv6 + - multi.c: IPv6 ifconfig-pool assignments + put to route-hash table + push to client + - pool.c: extend pools to handle IPv4+IPv6, and also return IPv6 address + IPv6 address saved to file if ifconfig-pool-persist is set + (but ignored on read due to the way pools work) + - mroute.c: handle reading src/dst addresses from IPv6 packets + (so multi.c can check against route-hash table) + handle printing of IPv6 mroute_addr structure + -

change Solaris comments from "known-broken" to "unknown" + + * tun.c: rework NetBSD tunnel initialization and tun_read() / tun_write() + to work the same way OpenBSD and NetBSD do - tunnel is put into + "multi-af" mode, and all packet read/write activity is prepended by + a 32 bit value specifying the address family. + + * TEST SUCCESS: NetBSD 5.0/Sparc64: client-ipv6 with route-ipv6 + + * TEST SUCCESS: MacOS X 10.5: client-ipv6 with route-ipv6 + + * (RE-)TEST SUCCESS: Linux/iproute2: server-ipv6 + Linux/ifconfig: client-ipv6 + FreeBSD 6.3: server-ipv6 + + * release as patch 20100103-1 + + * options.c: document all new options in "--help" + + * tun.c: fix typo in Solaris-specific section + + * socket.h, socket.c: change u_int32_t to uint32_t + (Solaris -

ifconfig works, route add does not give + errors, "netstat -rn" looks right, but packets are discarded unless + the routes are installed with "metric 0". So we just use "metric 0"... + + * CAVEAT: Solaris "ifconfig ... preferred" interferes with source address + selection. So if there are any active IPv6 interfaces configured with + "preferred", packets leaving out the tunnel will use the wrong source + IPv6 address. Not fixable from within OpenVPN. + + * CAVEAT2: Solaris insists on doing DHCPv6 on tun0 interfaces by default, + so DHCPv6 solicitation packets will be seen. Since the server end has + no idea what to do with them, they are a harmless nuisance. Fixable + on the Solaris side via "ndpd.conf" (see ``man ifconfig''). + + * release as patch 20100104-1 |
