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@

2013-11-15Rename the struct pf_divert variable in divert_packet() andLawrence Teo
divert6_packet() from "pd" to "divert" to match the rest of the source. I think "pd" was not a good name for a struct pf_divert because "pd" usually refers to a pf_pdesc. No object file change. OK benno@ bluhm@ henning@
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@

"clean that little thingy up" deraadt@
2013-11-13In in6_update_ifa(), don't set the TENTATIVE flag on an IPv6 address thatStefan Sperling
is marked as NODAD. Since we're not gonna do duplicate address detection for this address, the TENTATIVE flag won't get cleared, rendering the address unusable. The existing logic only checked whether DAD was enabled for the interface, but DAD can be configured on a per-address basis. ok sthen@ as part of a larger diff
2013-11-11Replace most of our formating functions to convert IPv4/6 addresses fromMartin Pieuchot
network to presentation format to inet_ntop(). The few remaining functions will be soon converted. ok mikeb@, deraadt@ and moral support from henning@

2013-10-24Significant namespace cleanup of netinet6 symbols.Theo de Raadt
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
2013-10-23Back when some NRL code was merged into KAME to create the *BSD IPV6Theo de Raadt
stack (factoid: by a bunch of people in my living room), some compatibility #define's were created to shim incompatible inpcb access methods. There was an understanding they would eventually be removed. Since they are error prone, and 1999 is a long time ago, now they die. ok mikeb claudio mpi

2013-10-21Enable IPv6 routing domain supportPeter Hessler
Started by claudio@ for IPv4, lots of heavy work by sperreault@ My part started at s2k11, continued at n2k12, g2k12, c2k12 and n2k13. Lots of help and hints from claudio and bluhm OK claudio@, bluhm@
2013-10-21Sprinkle a lot more IPv6 routing domains support in the kernel.Peter Hessler
Mostly mechanical, setting and passing the rdomain and rtable correctly. Not yet enabled. Lots of help and hints from claudio and bluhm OK claudio@, bluhm@
2013-10-20no need to make the icmp cksum "offloading" case special insofar that theHenning Brauer
cksum needs to be 0'd before, pf does that now (just like in the tcp/udp case) and nothing else uses the icmp "offloading" yet. with & ok bluhm
2013-10-20Put a large chunk of the IPv6 rdomain support in-tree.Peter Hessler
Still some important missing pieces, and this is not yet enabled. OK bluhm@
2013-10-19Our IPv6 stack was scanning all extension headers for routing headerAlexander Bluhm
type 0 and dropped the packet if it found one. RFC 5095 demands to handle a routing header type 0 like an unrecognised routing type. This is enough to protect the own machine. To protect a network as a firewall, we have pf which does the same full scan in pf_walk_header6(). As pf is enabled by default, nothing changes for most users. If you turn off pf on your router, you should not expect extra protection. Get rid of the double scanning in ip6_input() and and the older disabled code in route6_input(). No more special treatment of routing header type 0 in the IPv6 stack. OK henning@ mikeb@
2013-10-17The header file netinet/in_var.h included netinet6/in6_var.h. ThisAlexander Bluhm
created a bunch of useless dependencies. Remove this implicit inclusion and do an explicit #include <netinet6/in6_var.h> when it is needed. OK mpi@ henning@
2013-10-14Change the macros used to iterate over the multicast records of anMartin Pieuchot
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@

2013-08-26No one uses the obsolete IPv6 ioctls SIOCGDRLST_IN6, SIOCGPRLST_IN6,Alexander Bluhm
OSIOCGIFINFO_IN6 anymore. Remove them together with the structs in6_drlist, in6_oprlist, in6_prlist, in6_ondireq and the kernel implementation. OK mikeb@ henning@
2013-08-13Switch time_t, ino_t, clock_t, and struct kevent's ident and dataPhilip Guenther
members to 64bit types. Assign new syscall numbers for (almost all) the syscalls that involve the affected types, including anything with time_t, timeval, itimerval, timespec, rusage, dirent, stat, or kevent arguments. Add a d_off member to struct dirent and replace getdirentries() with getdents(), thus immensely simplifying and accelerating telldir/seekdir. Build perl with -DBIG_TIME. Bump the major on every single base library: the compat bits included here are only good enough to make the transition; the T32 compat option will be burned as soon as we've reached the new world are are happy with the snapshots for all architectures. DANGER: ABI incompatibility. Updating to this kernel requires extra work or you won't be able to login: install a snapshot instead. Much assistance in fixing userland issues from deraadt@ and tedu@ and build assistance from todd@ and otto@
2013-08-11To control the lifetime of IPv6 addresses, prefixes and defaultAlexander Bluhm
routers, the kernel and ndp use a bunch of expire fields. Before they were int or u_long, convert expire to time_t in all structs. Move vltime and pltime to u_int32_t everywhere. Sort struct fields by size. Struct inet6_ndpr_msghdr is not used at all, so remove it. Binary compatibility of rtsold and ndp break with this change as rtsold uses in6_drlist and ndp uses in6_defrouter and in6_prefix to interact with the kernel. OK mpi@

2013-06-26put the cksum diff back, of course with the bug fixed where we couldHenning Brauer
under some circumstances repair broken checksums on the way. ok ryan naddy mikeb . redo most of the protocol (tcp/udp/...) checksum handling -assume we have hardware checksum offloading. stop mucking with the checksum in most of the stack -stop checksum mucking in pf, just set a "needs checksumming" flag if needed -in all output pathes, very late, if we figure out the outbound interface doesn't have hw cksum offloading, do the cksum in software. this especially makes the bridge path behave like a regular output path -little special casing for bridge still required until the broadcast path loses its disgusting shortcut hacks, but at least it's in one place now and not all over the stack in6_proto_cksum_out mostly written by krw@ started at k2k11 in iceland more than 1.5 years ago - yes it took that long, this stuff is everything but easy. this happens to fix the infamous pf rdr bug that made us turn off proto cksum offloading on almost all interface drivers.
