2017-01-03Take the neighbor solicitation's source address from the packet toAlexander Bluhm
send if the mbuf contains the complete IPv6 header. The old check was wrong, it required one additional octet after the header. So the source address selection was depending on the layout of the mbuf chain. OK mpi@

2016-08-04Commit in6_selectsrc() split again, with missing assignment fixed.Vincent Gross
2016-07-22Revert in_selectsrc() refactoring, it breaks IPv6.Martin Pieuchot
Reported by Heiko on bugs@. ok stsp@, claudio@
2016-07-20Split in6_selectsrc() into a low-level part and a pcb-level part, andVincent Gross
convert in_selectsrc() prototype to match. Ok bluhm@ mpi@.

2016-06-15Kill nd6_output(), it doesn't do anything since the resolution logicMartin Pieuchot
has been moved to nd6_resolve(). ok visa@, millert@, florian@, sthen@
2016-06-01make nd6_llinfo_settimer take seconds instead of ticks.David Gwynne
most callers are working in seconds, internally it uses seconds, and you can call timeout_add_sec as easily as timeout_add. this also fixes an issue with an nd_defrouter expire which was incorrectly scaled with ticks in a comparison. ok mpi@

2015-12-09Keep all ether prototypes in one place.Martin Pieuchot
2015-11-18Factorize the bits to check if a L2 route is connected, wether it isMartin Pieuchot
attached to a carp(4) or bridge(4) member, to not dereference rt_ifp directly. ok visa@
2015-11-02Retire ARP load-balacing, thanks for all the fish!Martin Pieuchot
One of the keys of our MP work relies on making OpenBSD's kernel simpler! In this case turning ARP processing MP-safe is quite complicated due to the way carp(4) is hooked in arpinput() and nowadays you'd better run kitchensinkd(9) anyway :) ok bluhm@, claudio@, reyk@
2015-11-02Prefer an existing refcounted ``ifp'' to rt_ifp when possible or use theMartin Pieuchot
interface index directly. ok bluhm@
2015-10-22Inspired by satosin(), use inline functions to convert sockaddr dl.Alexander Bluhm
Instead of casts they check wether the incoming object has the expected type. So introduce satosdl() and sdltosa() in the kernel. OK mpi@
2015-09-18Do not manually decrement rt's refcounter in nd6_lookup() and let theMartin Pieuchot
callers rtfree(9) it. Inputs and ok bluhm@

2015-09-11Kill yet another argument to functions in IPv6. This time ip6_output'sClaudio Jeker
ifpp - XXX: just for statistics ifpp is always NULL in all callers so that statistic confirms ifpp is dying OK mpi@
2015-09-09Kill icmp6_ifstat_inc() and associated per-ifp storage.Martin Pieuchot
The SIOCGIFSTAT_ICMP6 is no longer supported. ok dlg@, mikeb@, claudio@
2015-08-24Rework the code to decide when to perform DAD to no longer rely on theMartin Pieuchot
IN6_IFF_NODAD pseudo-flag not being set. This was just a flag for spaghetti code that should not exist in the first place. Tested by sebastia@, ok sthen@
2015-07-16Kill incorrect and never set ``dad_ignore_ns'' button.Martin Pieuchot
ok phessler@
2015-06-16Store a unique ID, an interface index, rather than a pointer to theMartin Pieuchot
receiving interface in the packet header of every mbuf. The interface pointer should now be retrieved when necessary with if_get(). If a NULL pointer is returned by if_get(), the interface has probably been destroy/removed and the mbuf should be freed. Such mechanism will simplify garbage collection of mbufs and limit problems with dangling ifp pointers. Tested by jmatthew@ and krw@, discussed with many. ok mikeb@, bluhm@, dlg@
2015-03-14Remove some includes include-what-you-use claims don'tJonathan Gray
have any direct symbols used. Tested for indirect use by compiling amd64/i386/sparc64 kernels. ok tedu@ deraadt@
2014-12-17Remove the "multicast_" prefix from the fields a multicast-only struct.Martin Pieuchot
Prodded by claudio@ and mikeb@
2014-12-17Use an interface index instead of a pointer for multicast options.Martin Pieuchot
Output interface (port) selection for multicast traffic is not done via route lookups. Instead the output ifp is registred when setsockopt(2) is called with the IP{V6,}_MULTICAST_IF option. But since there is no mechanism to invalidate such pointer stored in a pcb when an interface is destroyed/removed, it might lead your kernel to fault. Prevent a fault upon resume reported by frantisek holop, thanks! ok mikeb@, claudio@
2014-12-05Explicitly include <net/if_var.h> instead of pulling it in <net/if.h>.Martin Pieuchot
ok mikeb@, krw@, bluhm@, tedu@
2014-11-20Rework the handling of interfaces and IPv6 addresses for local delivery.Martin Pieuchot
- Unicast packets sent to any local address will have their interface set to loobpack. - In order to differentiate traffic from interfaces having identical link-local addresses, provide the scoped addresses to pf(4). - Update the icmp6 state lookup logic to match scoped MLL addresses. - Remove a shortcut in ip6_input() that bypasses pf and always look for an RTF_LOCAL route. Packets sent to multicast addresses still retain their original interface due to the fact that local multicast packet delivering does not use if_output. This makes ping6 to link-local addresses work even with pf enabled and "set skip" on loopbacks, reported by Pieter Verberne. Debugged, analysed and tested with mikeb@. ok mikeb@, henning@, sthen@
2014-11-18move arc4random prototype to systm.h. more appropriate for most codeTed Unangst
to include that than rdnvar.h. ok deraadt dlg

2014-11-01Rename rtalloc1() into rtalloc(9) and convert its flags to only enableMartin Pieuchot
functionnality instead of a mix of enable/disable. ok bluhm@, jca@
2014-10-14Use rtfree() instead of RTFREE(), NULLify some free'd route pointers andMartin Pieuchot
kill the macro. ok mikeb@, henning@
2014-07-12add a size argument to free. will be used soon, but for now default to 0.Ted Unangst

2014-06-07g/c unused IFT_L2VLAN, ok reyk bluhmHenning Brauer
the #define stays since it's userland visible and who knows what uses it
2014-04-18Invert the signature logic of in{,6}_selectsrc, make them return theJeremie Courreges-Anglas
error code and pass the resulting source address back to the caller through a pointer, as suggested by chrisz. This gives us more readable code, and eases the deletion of useless checks in the callers' error path. Add a bunch of "0 -> NULL" conversions, while here. ok chrisz@ mpi@
2014-04-14"struct pkthdr" holds a routing table ID, not a routing domain one.Martin Pieuchot
Avoid the confusion by using an appropriate name for the variable. Note that since routing domain IDs are a subset of the set of routing table IDs, the following idiom is correct: rtableid = rdomain But to get the routing domain ID corresponding to a given routing table ID, you must call rtable_l2(9). claudio@ likes it, ok mikeb@
2014-03-21If a NA is received on a carp interface in BACKUP state and match oneMartin Pieuchot
of the carp addresses silently ignore it since it is certainly coming from the carp MASTER. ok sthen@
2014-01-24Instead of calculating the ICMPv6 checksum here, just set the flag thatChristian Weisgerber
is needed and the lower parts of the stack will take care of it. ok henning@, lteo@
2014-01-13Call all local valiables of type struct in6_ifaddr "ia6". This isAlexander Bluhm
consistent with struct ifaddr "ifa" and struct in_ifaddr "ia". OK mpi@
2014-01-07Propagate an rdomain number to the nd6_lookup independently fromMike Belopuhov
the ifp pointer which can be NULL. This prevents a crash reported by David Hill <dhill at mindcry ! org>. OK bluhm

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
2013-10-20Put 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@
2013-10-17The 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@
2013-05-31Remove a bunch of sockaddr_in6 pointer casts and replace othersAlexander Bluhm
with sin6tosa() or satosin6() inline functions. This allows the compiler to check the types more strictly. OK mpi@
