2017-08-11Validate sockaddr from userland in central functions. This resultsAlexander Bluhm
in common checks for unix, inet, inet6 instead of partial checks here and there. Some checks are already done at a higher layer, but better be paranoid with user input. OK claudio@ millert@
2017-07-13Get rid of ip6.maxifprefixes and ip6.maxifdefrouters, the kernel noFlorian Obser
longer tracks prefixes or default routers from router advertisements. Pointed out by jmc. ports tree grepping sthen, who only found nsh OK mpi, sthen
2017-05-30Keep ipv6_input() definition inside _KERNEL.Martin Pieuchot
Unbreak userland, found the hardway by deraadt@
2017-05-30Introduce ipv{4,6}_input(), two wrappers around IP queues.Martin Pieuchot
This will help transitionning to an un-KERNEL_LOCK()ed IP forwarding path. Disucssed with bluhm@, ok claudio@
2017-05-04Introduce sstosa() for converting sockaddr_storage with a type safeAlexander Bluhm
inline function instead of casting it to sockaddr. While there, use inline instead of __inline for all these conversions. Some struct sockaddr casts can be avoided completely. OK dhill@ mpi@
2017-02-22Fix comments about a few ipv6 sockoptionsRenato Westphal
OK millert@ florian@
2016-12-22Remove PIM support from the multicast stack.Rafael Zalamena
ok mpi@
2016-10-03Convert some of the remaining usages of time_second to time_uptime.Martin Pieuchot
time_second is unix time so it can be affected by clock changes. time_uptime is monotonic so it isnt affected by clock changes. that in turn means route expiries wont jump with clock changes if set against time_uptime. the expiry is translated into unix time for export to userland though. Should fix mismatch between route timers that were already converted and ND default routers that were still using time_second. Tested by matthieu@ and sthen@ ok sthen@, dlg@
2016-06-27Implement IPV6_MINHOPCOUNT support.Jeremie Courreges-Anglas
Useful to implement GTSM support in daemons such as bgpd(8). Diff from 2013 revived by renato@. Input from bluhm@, ok bluhm@ deraadt@
2016-06-01Kill sysctl net.inet6.ip6.rr_pruneJeremie Courreges-Anglas
We don't support Router Renumbering and there are no plans to change that. ok mpi@
2016-05-19Remove sysctl net.inet6.ip6.v6onlyJeremie Courreges-Anglas
This sysctl is a no-op, read-only since it was introduced. There are no plans to support IPv4-mapped addresses on OpenBSD, thus this sysctl is meaningless. Noticed by djm@, ok claudio@ mpi@ sthen@ henning@
2015-12-03rm unused kernel only IPV6_RECVRTHDRDSTOPTS sockopt. ok deraadt sthenTed Unangst
2015-10-29RFC 2292 API support was removed 9 years ago, but left in a binary compatTed Unangst
ABI form for the sake of existing programs. no programs from that era have been able to run for quite some time. Kill it all. ok deraadt florian millert mpi (I believe this is my first IPv6 diff. Future, here I come!)
2015-09-11in6_embedscope() needs to lose some weight. Remove the last argument.Claudio Jeker
In all but two calls NULL is passed and in the other 2 cases the ifp is only used to maybe feed it to in6_selecthlim() to select the hoplimit for the link. Since in6_embedscope() only works on link-local addresses it does not matter what hop limit we select since the destination is directly reachable. OK florian@ mpi@
2015-09-10It is time to put inet6 on a diet. Use the flensing knife and cut outClaudio Jeker
the 3rd argument of in6_recoverscope() and make it return void. OK dlg@ mikeb@
2015-06-08More damned eye searing whitespace. No change to .o files.Kenneth R Westerback
2015-04-14ip6_sprintf is long gone; noticed by blambertMike Belopuhov
2015-04-10replace the use of ifqueues for most input queues serviced by netisrDavid Gwynne
with niqueues. this change is so big because there's a lot of code that takes pointers to different input queues (eg, ether_input picks between ipv4, ipv6, pppoe, arp, and mpls input queues) and falls through to code to enqueue packets against the pointer. if i changed only one of the input queues id have to add sepearate code paths, one for ifqueues and one for niqueues in each of these places by flipping all these input queues at once i can keep the currently common code common. testing by mpi@ sthen@ and rafael zalamena ok mpi@ sthen@ claudio@ henning@
2015-02-09Implement 2 sysctl to retrieve the multicast forwarding cache (mf6c) and theClaudio Jeker
multicast interface table (mif6). Will be used by netstat soon. Looked over by guenther@
2015-02-09provide a net.inet6.ip6.ifq sysctl so people can see and fiddleDavid Gwynne
with the ip6intrq. ok claudio@
2015-01-10Correct some comments and merge in6_if_up() into in6_ifattach() toMartin Pieuchot
reflect that IPv6 link-local addresses are no longer automagically configured the first time an interface is brought up. ok henning@, stsp@

in kernel and user land. OK florian@ mpi@

pointed out & OK bluhm@
2014-07-11introduce the IFXF_AUTOCONF6 interface flag which controls wether weHenning Brauer
accept rtadvs on that interface. the global net.inet6.ip6.accept_rtadv sysctl just doesn't cut it, even tho the spec wants that - but in their little absurd world, a host just has one interface by definition anyway... the sysctlgoes away. lots of head scratching, brain cell elemination etc from bluhm benno stsp florian, excitement from simon and todd, ok bluhm stsp benno florian
2014-06-13Remove deprecated RFC2292 ancillary data convenience functions.Christopher Zimmermann
They are obsoleted by the RFC3542 api. ok mpi@

2014-01-22Split the checksum calculation for IPv6 like for IPv4:Christian Weisgerber
Always calculate the pseudo-header checksum. Complete the checksum if hardware offload is not available. Parts originally from NetBSD; ok henning@

global variables to in6.h. ok deraadt@
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
2013-10-21There are gasps of shock! Add a pmtu delay sysctl BUTTON for netinet6,Theo de Raadt

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.
2013-03-28Convert the satosin, sintosa, ifatoia, satosin6, sin6tosa, ifatoia6Alexander Bluhm
defines into static inline functions. This allows the compiler to check the source type before casting. liked by many; OK mpi@ haesbaert@

2011-10-13Since the IPv6 madness is not enough introduce NAT64 -- which is actuallyClaudio Jeker
"af-to" a generic IP version translator for pf(4). Not everything perfect yet but lets fix these things in the tree. Insane amount of work done by sperreault@, mikeb@ and reyk@. Looked over by mcbride@ henning@ and myself at eurobsdcon. OK mcbride@ and general put it in from deraadt@

2010-05-07Start cleaning up the mess called rtalloc*. Kill rtalloc2, make rtalloc1Claudio Jeker
accept flags for report and nocloning. Move the rtableid into struct route (with a minor twist for now) and make a few more codepathes rdomain aware. Appart from the pf.c and route.c bits the diff is mostly mechanical. More to come... OK michele, henning
