* Copy the user provided sockaddr into a normalized sockaddr in rtrequest()claudio2019-06-131-1/+2
| | | | | | | | | | before adding it to the routing table. The rtable code is doing memcmp() of those rt_dest sockaddrs so it is important that they are stored in a canonical form. To do this struct domain is extended to include the sockaddr size for this address family. OK bluhm@ anton@ Reported-by: syzbot+10fe9cd8d0211c562ead@syzkaller.appspotmail.com
* Retire dom_rtkeylen from struct domain. Nothing is using this anymore.claudio2018-11-191-2/+1
| | | | | It was used by the original patricia tree. OK mpi@
* rework gif to be more consistent.dlg2018-02-101-2/+18
| | | | | | | | | while here, give us support for mpls in gif on ipv6. this moves all the gif handling into if_gif, eg, the mpls handling is no longer in ip_etherip.c. ok claudio@
* update the gre driver.dlg2018-02-071-1/+19
| | | | | | | | | | | the main new feature is gre keys, supported by the vnetid ioctls. this also adds support for gre over ipv6, the use of hfsc, and allows tx mitigation in the future. this diff removes keepalive support, but i promised claudio@ and patrick@ i would put it back after this goes in. ok claudio@

* Drop all Ethernet-in-IP support from gif(4)jca2017-11-171-14/+1
| | | | | As a result, ip_ether.c now only deals with MPLS-in-IP. The next commits will move & rename stuff to make this clear. ok visa@ mpi@
* Remove inet6 etherip sysctl entriesjca2017-11-151-3/+1
| | | | | | | The INET6 entries are not needed, not documented (use net.inet.etherip) and do not appear in sysctl(8) output. ok mpi@

* The function name ip4_input() is confusing as it also handles IPv6bluhm2017-05-181-3/+3
| | | | | | | | | | packets. This is the IP in IP protocol input function, so call it ipip_input(). Rename the existing ipip_input() to ipip_input_gif() as it is the input function used by the gif interface. Pass the address family to make it consistent with pr_input. Use __func__ in debug print and panic messages. Move all ipip prototypes to the ip_ipip.h header file. OK dhill@ mpi@
* The large and nested GIF #ifdef in protosw made it hard to figurebluhm2017-05-171-30/+16
| | | | | | out what is going on. There were also some inconsistencies that seem to be oversights. Use more specific the #ifdefs. OK mpi@
* Remove rip_output() and rip6_output() from inetsw and inet6sw. Thebluhm2017-05-091-14/+1
| | | | | | | rip_output() function is never called via the pr_output pointer. rip_usrreq(PRU_SEND) calls rip_output() directly. raw_usrreq() is never called from inetsw. Situation in inet and inet6 is analog. OK claudio@ mikeb@
* Move PRU_ATTACH out of the pr_usrreq functions into pr_attach.claudio2017-03-131-4/+20
| | | | | | | Attach is quite a different thing to the other PRU functions and this should make locking a bit simpler. This also removes the ugly hack on how proto was passed to the attach function. OK bluhm@ and mpi@ on a previous version
* Convert domain declarations to C99 initializers.mpi2017-03-021-8/+12
| | | | ok dhill@, florian@, bluhm@
* Use c99 struct initialization with protosw.dhill2017-02-221-90/+187
| | | | | | | This makes it easier to grep for a member, such as .pr_usrreq, and know which functions to review. ok mpi@ bluhm@ jca@
* Change the IPv4 pr_input function to the way IPv6 is implemented,bluhm2017-01-291-8/+8
| | | | | | | to get rid of struct ip6protosw and some wrapper functions. It is more consistent to have less different structures. The divert_input functions cannot be called anyway, so remove them. OK visa@ mpi@

* Kill sysctl net.inet6.ip6.rr_prunejca2016-06-011-3/+1
| | | | | We don't support Router Renumbering and there are no plans to change that. ok mpi@
* Remove sysctl net.inet6.ip6.v6onlyjca2016-05-191-2/+1
| | | | | | | | 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@
* Get rid of rt_mask() and stop allocating a "struct sockaddr" for everympi2015-12-031-2/+2
| | | | | | | | | | | | | route entry in ART. rt_plen() now represents the prefix length of a route entry and should be used instead. For now use a "struct sockaddr_in6" to represent the mask when needed, this should be then replaced by the prefix length and RTA_NETMASK only used for compatibility with userland. ok claudio@
* Implement etherip(4) drivergoda2015-12-031-1/+13
| | | | | | | This commit is not removing the existing EtherIP part of gif(4) and it keeps EtherIP of gif(4) working. ok jbg@ sthen@ mpi@ reyk@ yasuoka@
* Initialize the routing table before domains.mpi2015-10-071-3/+3
| | | | | | | | | | | | | | | | | | | | | | | The routing table is not an optional component of the network stack and initializing it inside the "routing domain" requires some ugly introspection in the domain interface. This put the rtable* layer at the same level of the if* level. These two subsystem are organized around the two global data structure used in the network stack: - the global &ifnet list, to be used in process context only, and - the routing table which can be read in interrupt context. This change makes the rtable_* layer domain-aware and extends the "struct domain" such that INET, INET6 and MPLS can specify the length of the binary key used in lookups. This allows us to keep, or move towards, AF-free route and rtable layers. While here stop the madness and pass the size of the maximum key length in *byte* to rn_inithead0(). ok claudio@, mikeb@

* Make every subsystem using a radix tree call rn_init() and pass thempi2015-09-041-2/+1
| | | | | | | | | | | | | | | length of the key as argument. This way every consumer of the radix tree has a chance to explicitly initialize the shared data structures and no longer rely on another subsystem to do the initialization. As a bonus ``dom_maxrtkey'' is no longer used an die. ART kernels should now be fully usable because pf(4) and IPSEC properly initialized the radix tree. ok chris@, reyk@
* Use a global table for domains instead of building a list at run time.mpi2015-08-301-2/+2
| | | | | | | As a side effect there's no need to run if_attachdomain() after the list of domains has been built. ok claudio@, reyk@
* Abstract the routing table internals behind an rtable_* API.mpi2015-07-181-10/+3
| | | | | | | | | | Code abusing the radix internals for the routing table should now includes <net/rtable.h> and only deal with "struct rtentry". Code using a radix tree for another purpose can still include <net/radix.h>. Inputs from and ok claudio@, mikeb@
