Remove support for semantically opace interface identifiers (RFC 7217) for IPv6 link local addresses. Some hosting and VM providers route customer IPv6 prefixes to link local addresses derived from ethernet MAC addresses (RFC 2464). This leads to hard to debug IPv6 connectivity problems and is probably not worth the effort. RFC 7721 lists 4 weaknesses: 3.1. Correlation of Activities over Time & 3.2. Location Tracking These are still possible with RFC 7217 addresses for an adversary connected to the same layer 2 network (think conference wifi). Since the link local prefix stays the same (fe80::/64) the link local addresses do not change between different networks. An adversary on the same layer 2 network can probably track ethernet MAC addresses via different means, too. 3.3. Address Scanning & 3.4. Device-Specific Vulnerability Exploitation These now become possible, however, as noted above a layer 2 adversary was probably able to do this via different means. People concerned with these weaknesses are advised to use ifconfig lladdr random. OK benno input & OK kn

Implement RFC 7217: "A Method for Generating Semantically Opaque Interface Identifiers with IPv6 Stateless Address Autoconfiguration." "An IPv6 address configured using this method is stable within each subnet, but the corresponding Interface Identifier changes when the host moves from one network to another. This method is meant to be an alternative to generating Interface Identifiers based on hardware addresses." OK naddy, sthen

Ensure that link-local addresses are correctly configured on loopback interfaces. When the kernel automagically configures IPv6 addresses on loopback interfaces, start by assigning a link-local address and then try to assign "::1". Only the first configured loopback interface per rdomain can have the "::1" address. But even if other loopback interfaces failed to get this address, because it is already taken, give them a chance to have a link-local address. While here change in6_ifattach() to return an error value and remove duplicated code. Fix a regression introduced by the NOINET6 flag removal. ok henning@, stsp@, florian@, benno@

Some follow-up fixes for IFID collision handling in IPv6CP. Really change the link-local address in the unlikely event of an IFID collision, instead of going into an infinite conf-nak loop with the peer. To make the netinet6 code use the IPv6CP IFID in a new link-local address, in6_ifattach_linklocal() must accept a provided IFID. Replace the unused 'altifp' parameter with a new 'ifid' parameter for this purpose. Always use the latest suggested address in IPv6CP replies, even if the task to update the interface's address hasn't run yet. Also, clear the ifindex (KAME hack) in addresses sent during IPv6CP. ok mpi

Automatically add a IPv6 link-local address to carp interfaces when the virtual MAC address is set. Among other things, this makes route6d work correctly on systems with carp interfaces. In order to ensure backwards compatibility, we do not include IPv6 link-local addresses in generating the HMAC, but we accept HMACs with AND without the link-local addresses. They will be added to the HMAC in a future release. In short: this change should only affect backwards compatibility for IPv6 users who are manually adding link-local addresses on carp interfaces. testing mtu@ todd@ ok mpf@ henning@ deraadt@

sync with latest KAME in6_ifaddr/prefix/default router manipulation. behavior changes: - two iocts used by ndp(8) are now obsolete (backward compat provided). use sysctl path instead. - lo0 does not get ::1 automatically. it will get ::1 when lo0 comes up.

revisit in6_ifattach(). (1) make it more persistent about initializaing an interface (2) cleanup interface id selection. run NUD on p2p interface (required by spec for bidir p2p interface). add "ndp -i interface" (can tweak per-interface ND flag). (sync with more recent kame)

bring in KAME IPv6 code, dated 19991208. replaces NRL IPv6 layer. reuses NRL pcb layer. no IPsec-on-v6 support. see sys/netinet6/{TODO,IMPLEMENTATION} for more details. GENERIC configuration should work fine as before. GENERIC.v6 works fine as well, but you'll need KAME userland tools to play with IPv6 (will be bringed into soon).
