* Do not clean the multicast records of an interface when it is destroyedmpi2014-01-211-11/+1
| | | | | | | | | | | (unplugged). Even if it makes no sense to keep them around if the interface is no more, we cannot safely remove them since pcb multicast options might keep a pointer to them. Fixes a user after free introduced by the multicast address linking rewrite and reported by Alexey Suslikov, thanks! ok claudio@
* Call all local valiables of type struct in6_ifaddr "ia6". This isbluhm2014-01-131-10/+10
| | | | | consistent with struct ifaddr "ifa" and struct in_ifaddr "ia". OK mpi@
* Some follow-up fixes for IFID collision handling in IPv6CP.stsp2014-01-071-19/+15
| | | | | | | | | | | | | | | 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
* Make in6_ifdetach() remove the ff01::1 route for the detaching interface, too.stsp2014-01-061-1/+21
| | | | | The route used to linger after an interface detached from IPv6. ok mikeb
* Change the way protocol multicast addresses are linked to an interface.mpi2013-11-281-6/+11
| | | | | | | | | | | | | | | | | | | | | | Instead of linking multicast records to the first configured address of the corresponding protocol, making this address and its position in the global list special, add them to a new list directly linked to the interface descriptor. This new multicast address list is similar to the address list, all its elements contain a protocol agnostic part. This design allows us to be able to join a multicast group without necessarily having a configured address. That means IPv6 multicast kludges are no longer needed. Another benefit is to be able to add and remove an IP address from an interface without worrying about multicast records. That means that the global IPv4 list is no longer needed since the first configured address of an interface is no longer special. This new list might also be extended in the future to contain the link-layer addresses used to configure hardware filters. Tested by sthen@ and weerd@, ok mikeb@

* The header file netinet/in_var.h included netinet6/in6_var.h. Thisbluhm2013-10-171-2/+2

* Remove a bunch of sockaddr_in6 pointer casts and replace othersbluhm2013-05-311-2/+2

* Remove a block of dead code in in6_ifdetach(). It was never executedbluhm2013-03-261-51/+1
| | | | | | | | | due to the wrong & in satosin6(&ifa->ifa_addr). The link local prefix fe80 was not checked within the IPv6 address, but within some pointers of the interface address struct. The whole loop around this was also never executed as all IPv6 addresses had already been purged. OK sperreault@ mpi@ mikeb@

* Automatically add a IPv6 link-local address to carp interfaces when themcbride2006-08-311-8/+11
| | | | | | | | | | | | | | | | 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@
