2007-10-08 Stefan Siegl <stesie@brokenpipe.de>

	* config.h (CONFIG_IPV6, CONFIG_IPV6_EUI64): New defines,
	set to 1.
	* Makefile (ipv6-srcs): New variable.
	(LINUXSRCS): Add ipv6-srcs.

	* ethernet.c (ethernet_demuxer): Call skb_put instead of changing
	skb->len directly, and thus now update skb->tail accordingly.
	* pfinet.h (PORTCLASS_INET, PORTCLASS_INET6): New enums.
	(trivfs_protid_portclasses, trivfs_protid_nportclasses)
	(trivfs_cntl_portclasses, trivfs_cntl_nportclasses): Declare
	these.
	(pfinet_bootstrap_portclass): New variable.
	(pfinet_bind): New function.
	* main.c: Define _HACK_ERRNO_H.  Include <errno.h>.
	(trivfs_protid_portclasses, trivfs_cntl_portclasses): New slots
	for PORTCLASS_INET6.
	(trivfs_protid_nportclasses, trivfs_cntl_nportclasses): Set to 2.
	(pfinet_bootstrap_portclass): New variable.
	(pfinet_bind): New function.
	(pfinet_activate_ipv6) [CONFIG_IPV6]: New function.
	(main) [CONFIG_IPV6]: Call inet6_proto_init.
	(main): Reordered to allow pfinet to not be started as a
	translator, if pfinet_bind is used.  If started as a translator,
	treat pfinet_bootstrap_portclass when calling trivfs_startup.
	* options.c: Include <net/sock.h>, <net/ip6_fib.h>,
	<net/ip6_route.h> and <net/addrconf.h>.
	(options): New option `ipv4'.
	(options) [CONFIG_IPV6]: New options `ipv6', `address6' and
	`gateway6'.
	(parse_interface) [CONFIG_IPV6]: Add address6 and gateway6.
	(parse_hook_add_interface) [CONFIG_IPV6]: Initialize address6 and
	gateway6.
	(parse_opt): Parse new args.
	* socket-ops.c (S_socket_create): Call either
	net_families[PF_INET]->create or net_families[PF_INET6]->create,
	depending on receiving master.
	(S_socket_create_address): Allow creation of AF_INET6 addresses.

	* glue-include/asm/delay.h: New stub file.
	* glue-include/linux/ipv6.h: Merged many bits unmodified from Linux
	header file.
	* glue-include/linux/in6.h: Likewise.
	(ipv6mr_ifindex): New define, glue to ipv6mr_interface.
	* glue-include/linux/socket.h (SOL_IPV6, SOL_ICMPV6): New defines.

	* linux-src/net/ipv6/addrconf.c (ipv6_find_idev, inet6_addr_add)
	(inet6_addr_del) [_HURD_]: Make these non-static.
	(addrconf_set_dstaddr, addrconf_add_ifaddr, addrconf_del_ifaddr)
	[_HURD_]: Don't define these functions.
	* linux-src/net/ipv6/route_ipv6.c (ipv6_route_ioctl) [_HURD_]:
	Likewise.
	* linux-src/net/ipv6/af_inet6.c (inet6_ioctl) [_HURD_]: Don't
	define the function, instead #define it to 0.
	(inet6_proto_init) [_HURD_]: Don't call sit_init.
	* linux-src/net/ipv6/udp_ipv6.c (udp_ioctl) [_HURD_]: Define
	to 0.
	(udp_v6_get_port): Put empty statement after label to silence
	compiler.
	* linux-src/net/ipv6/tcp_ipv6.c (tcp_v6_get_port, tcp_v6_rcv):
	Likewise.
	* linux-src/net/ipv6/icmpv6.c (icmpv6_rcv): Likewise.
	(icmpv6_init) [_HURD_]: Don't initialize i_uid and i_gid.
	* linux-src/net/ipv6/mcast.c (igmp6_init): Likewise.
	* linux-src/net/ipv6/ndisc.c (ndisc_init): Likewise.
	* linux-src/net/ipv6/ip6_fib.c (BUG_TRAP): Don't use __FUNCTION__
	as a string but a variable, to keep gcc happy.
	(fib6_walker_list): Make it non-static, to keep gcc happy.
	* linux-src/net/ipv6/ip6_flowlabel.c (fl_create) [_HURD_]: Drop
	IPV6_FL_S_USER support, since current->euid is not available.
