2014-01-21Cleanup the abuse of x as the rn_addmask radix node. Since in mostClaudio Jeker
cases x is just used as a temp variable. Main offender is rn_addmask() which sets x once at the top uses it then late in the function and then starts reuing it for various other stuff. While there fix some for loops to while ones and fix one strange do { } while() loop. And since rn_search() can not return NULL remove one extra check. OK mpi@

2014-01-21Do not clean the multicast records of an interface when it is destroyedMartin Pieuchot
(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@

Also remove a memset that is already happeing because we use PR_ZERO on the allocation. Move two memmove to memcpy because the addrs can not overlap. Make some simple helper functions static __inline and remove one of the explicit rn_search inlines. OK mpi@

2014-01-07Some follow-up fixes for IFID collision handling in IPv6CP.Stefan Sperling
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

2013-11-28Change the way protocol multicast addresses are linked to an interface.Martin Pieuchot
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@

2013-11-15After discussion with deraadt@ and Fernando Gont, it seems that theAlexander Bluhm
stack should still scan for IPv6 type 0 routing headers. There are OpenBSD routers running without pf and there are plenty of legacy implementations supporting RH0. Bring back the function ip6_check_rh0hdr() that I removed a month ago. As an improvement to the prevoius solution, only scan the header chain in ip6_input() if the packet has not been inspected by pf. Both implementations drop packets with RH0 anywhere in the extension header chain. OK mikeb@ henning@
