	net/ipv4/tcp_ipv4.c,net/ipv6/udp.c,net/ipv6/tcp_ipv6.c}:
	CONFIG_NET_NEW_BIND_SEMANTICS:
	- as a result of local discussion, we've decided not to introduce
	SO_REUSEPORT socket options.
	- By theory, SO_REUSEPORT-like behavior is allowed only if the 
	addresses are multicast addresses.
	- Don't mix SO_REUSEADDR and SO_REUSEPORT.
	* kernel/linux2{2,4}/{net/ipv4/udp.c,net/ipv4/tcp_ipv4.c,
	net/ipv6/udp.c,net/ipv6/tcp_ipv6.c}:

	rule with CONFIG_NET_NEW_BIND_SEMANTICS.

2001/05/23	yoshfuji
	* kernel/linux24/net/{ipv4/tcp_ipv4,ipv6/tcp_ipv6}.c:
	fixed bind(2) semantics for TCP sockets with 
	CONFIG_NET_NEW_BIND_SEMANTICS; binding socket with SO_REUSExxx 
	should be succeeded even if existing sockets were in listen state.
	(found by bindtest(1) tool)

2001/05/22	yoshfuji
	* {usagi,src}/bindtest: build and install bindtest. (from KAME)

2001/05/22	yoshfuji
	* kernel/linux2{2,4}/net/ipv6/raw.c: Do not allow user to do
	bind(2)/sendmsg(2) with port number other than 0 or protocol that 
	has been specified to the socket(2) call for raw sockets.

2001/05/22	takamiya
	* src/radvd/send.c: ensure to initialize destination socket address
	structure when sendint RA message; previously, bind(2) failed with 
	EINVAL.

	in specific ipv4 vs specific ipv4 case.

2001/05/20	yoshfuji
	* kernel/linux2{2,4}/net/ipv6/icmp.c: 
	- icmpv6 checksum error is now considered as KERN_WARNING level.
	- print type, code and source address against unknown icmpv6 message
	if CONFIG_IPV6_DEBUG is set; otherwise, don't print anything.
	- Silent discard invalid Node Information Query message without
	CONFIG_IPV6_NODEINFO_DEBUG.
	* kernel/linux2{2,4}/net/ipv6/mcast.c:
	- socket creation failure is now on KERN_ERR level.
	- MLD6 without linklocal address is now on KERN_WARNING level.

2001/05/17	takamiya
	* kernel/linux24/net/ipv6/mobile_ip6/ha.c: fixed ND option parsing

	net/ipv6/addrconf.c,net/ipv6/af_inet6.c,Documentation/Configure.help},
	src/iproute2/ip/iptunnel.c, src/net-tools/iptunnel.c:
	tunlXX device can transport ipv6 packet with CONFIG_NET_IPIP_IPV6;
	IPv6 over IPv4 support and IPv4 over IPv4 support has been integrated
	and sitXX will be dissappeared.

	Note: You should use patched command(s) to manipulate tunnels.

	XXX: modulized ipv6 and ip tunneling interactions. 

	* usagi/configure{,.in},usagi/iptunnel: build and install iptunnel.

2001/05/16	yoshfuji

2001/05/16	yoshfuji
	* kernel/linux2{2,4}/net/ipv4/{ipip,ip_gre}.c: ensure to set 
	tunnel device name to internal tunnel parameter; now the ip

2001/05/02,07	yoshfuji
	* kernel/linux24: linux-2.4.4.

2001/05/01	sekiya
	* usagi/ndp/: provide ndp command which is compatible with KAME.

	* kernel/linux2{2,4}/net/{ipv4/udp.c,ipv4/tcp_ipv4.c,
	ipv6/udp.c,ipv6/tcp_ipv6.c} etc.: New bind(2) semantics has been 
	introduced with CONFIG_NET_NEW_BIND_SEMANTICS.  Hilights are:
	- Now we do not allow double bind as default;  it is allowed only if 
	IPV6_V6ONLY socket option is set to the inet6 socket.
	- implemented SO_REUSExxx more strictly.
	- binding more specific interfaces attack are forbidden.
	XXX: fast-reuse
	XXX: more description
