* Rename IN6_IFF_PRIVACY to IN6_IFF_TEMPORARY.florian2020-07-031-2/+2
| | | | | | | | This is the name the other BSDs use for this, there is no reason to be different, the IPv6 RFCs call these addresses temporary, and some software in ports wants to use this as well. Most recently pointed out for firefox by landry. OK claudio, sthen

* After we stopped processing router advertisements in the kernelflorian2017-08-151-2/+1
| | | | | | | | sppp_update_ip6_addr() became the last user of n6_are_prefix_equal(). Since it compares /128 prefixes it doesn't need all the bells and whistles and can be converted to a memcmp. Remove the now unused n6_are_prefix_equal(). OK bluhm, mpi

| | | | | | | | | shall all be cleansed. Remove sending of router solicitations and processing of router advertisements from the kernel. It's handled by slaacd(8) these days. Input & OK bluhm@, mpi@

* Move the ioctl(2) logic of in{,6}_control() into two new functionsmpi2016-06-131-1/+2
| | | | | | | | | in{,6}_ioctl() that do not deal with sockets. This will allow to automagically configure interface addresses in the kernel without too many layer violations. Required by upcoming umb(4).
* Kill IPv6 prefix and router renumbering ioctls.jca2016-03-031-95/+1
| | | | | | | | Router renumbering was never supported, prefix ioctls were deprecated ~15 years ago. Move some items in netinet6/nd6.h where they are still used. ok mikeb@ mpi@
* Delete all traces of SIOCSIF(ADDR|DSTADDR|NETMASK)_IN6jca2016-03-031-11/+1
| | | | | | | Those ioctls never made sense, IPv6 was designed right from the start with support for multiple addresses by interface. ok mikeb@ mpi@
* Remove SIOCSIFALIFETIME_IN6 ioctl, as NetBSD did.stefan2016-02-281-2/+1
| | | | | | | | | | | As described in NetBSD kern/35897 PR, the parameters this ioctl needs overlay each other in a union. The ioctl cannot have worked properly. Discovered while discussing overflow checks with mmcc@ and mpi@ The checks were part of the removed code. ok deraadt@

| | | | | | | | | | | | | | | processing of router advertisements was already in the kernel. With this rtsol{,d}(8) is no longer necessary. The kernel starts sending solicitations with # ifconfig $IF inet6 autoconf or inet6 autoconf in /etc/hostname.$IF. input stsp@ much help & OK mpi@ tweaks & OK bluhm@
* Introduce rt_ifa_{add,del}loop() to replace in6_{add,rem}loop().mpi2014-04-031-3/+1
| | | | | | | | | Move these functions to a more generic place and make them reuse existing code, they'll be soon used in IPv4 too. Tested by André Lucas, Vigdis and sthen@, thanks! ok sthen@
* Stop mixing interface address flags with routing entry ones.mpi2014-03-271-2/+2
| | | | | | | | | | Instead of always copying ifa_flags to the routing entry flags when creating a route by calling rtinit(), explicitly pass the RTF_CLONING flag when required. This means ifa_flags are now *only* used to check if an address has an associated route that was created by the kernel auto-magically. ok benno@
* Do not clean the multicast records of an interface when it is destroyedmpi2014-01-211-2/+2
| | | | | | | | | | | (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@
* Change the way protocol multicast addresses are linked to an interface.mpi2013-11-281-47/+23
| | | | | | | | | | | | | | | | | | | | | | 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@

* Significant namespace cleanup of netinet6 symbols.deraadt2013-10-241-7/+5
| | | | | | | | One worrying bit is in icmp6.h where some htols() and htonl() are added, which may affect compatibility down the line. This component can be reverted if issues show up. Ports tree greps indicate no issue. ok claudio mpi etc
* Change the macros used to iterate over the multicast records of anmpi2013-10-141-58/+22
| | | | | | | | | | interface to not depend on the global list of addresses. For IPv4 the IP_TO_IA() macro still depends on the global list of addresses because we want to be sure to grab the first configured address of an interface, where the records are linked. Tested by sthen@, ok henning@
