Rework parse_notification() to use the ibuf API for everything. While there fix the RFC5492 handling of ERR_OPEN_CAPA (the current code has the logic inversed). ERR_OPEN_CAPA is there to signal that a needed capability is missing in our OPEN message. Just add the handling of ERR_OPEN_CAPA to log_notification().

Improve IPv6 link-local address handling When a session is established determine the possible interface scope of that session. The scope is only set when the remote address is directly connected.

Implement ASPA support in RTR by following draft-ietf-sidrops-8210bis-10. In rtr.c renamed rtr_aspa_merge_set() to rtr_aspa_insert() and move it close to rtr_roa_insert(). In rtr_proto.c most complexity comes from the version negotiation. The ASPA parser is reasonably streight forward. The version negotiation is fragile but that is mostly because of the protocol specification and the fact that RTR cache daemons sometimes fail to send errors. OK tb@

Major rework of RFC9234 support. My initial interpretation of the RFC was too conservative. Fixes and changes include: - add role output to bgpctl, also adjust the capability output. Note, this changes the JSON output of neighbors a bit. - adjust the config parser to enable the RFC9234 role capability when there is a role set. iBGP and sessions with no role will not announce the role capability. - adjust the role capability announcement to be only on sessions that use either AFI IPv4 or IPv6 and SAFI 1 (AID_INET, AID_INET6). - if there is an OPEN notification indicating that the role capability is bad only disable the capability if it is not enforced. - Adjust capability negotiation, store remote_role on the peer since the neighbors role is no longer needed by the RDE. - inject the OTC attribute on ingress only for AID_INET and AID_INET6. For other AIDs clear the F_ATTR_OTC_LOOP flag. - Adjust the role logic in the RDE and use the peer->role (local role of the system) for all checks. Also remove the check if the role capability was negotiated between peers. - In prefix_eligible() check also if the F_ATTR_OTC_LOOP flag is set. The RFC requires that prefixes must be considered ineligible (and not treat as withdraw as done before) - When generating an UPDATE include the OTC attribute unless the AID is neither AID_INET or AID_INET6.

Instead of relaying struct peer from the SE to the RDE to fill out 10 stat numbers, just send the peerid and have the RDE response with the stats.

Add add-path support in MRT dumps (RFC8050). This works for table-v2 formats and also for the all and update dumps. For the latter the code needs to inspect the UPDATE message to guess if add-path is used in that message or not. Add-path can be enabled per AFI and alters the NLRI encoding without any way to detect. For table dumps we decided to dump RIB_GENERIC entires the same way as gobgp and not use the encoding from the RFC. The RFC specifies that RIB_GENERIC (non-IPv4/v6) entries in a way that is not only different but also against the normal codeflow. Only gobgp seems to implement RIB_GENERIC encoding (neither bird nor frr/quagga do) and so it makes sense to follow their way. OK benno@

It adds the capability parsers for the two no capabilities, extends the capability struct and adds the capability negotiation bits. The route refresh message parser and generator are extended to support the BoRR and EoRR message. Also add the new NOTIFICATION type and subtype for the route refresh message.

BGP uses KEEPALIVE packets and the HOLD timer to detect stalled sessions. The problem is that this timer only looks at the receive side of the TCP session. If for some reason the send side stalls the system fully depends on the remote BGP peer to reset the session. As seen in an ever growing OutQ and as a result important changes can get stalled and cause routing troubles. This change introduces a SEND HOLD timer. The timer is reset whenever the session engine was able to write data to the TCP socket. If the send hold timer expires bgpd was not able to send any data to that neighbor for at least 90 seconds and therefor the session is forcefully closed with a hold timer expired notification. The send hold timer acts as a last resort to detect faulty peers. On an idle session it can take a long time until this timer triggers but the main goal here is to reset a stuck session at some point which did not happen before. With and OK job@

Major refactoring of the RIB handling code. Mainly change how the RIB is walked. rib_dump_r() is now an internal function and instead the code gets an additional callback for throttling the rib_dump code. This removes a lot of similar code used to make sure the RDE is not walking to fast and replaces it with simpler callbacks. The other big change is the removal of struct rib pointers in other data structures.

Tested by me with 100 peers * 2000 prefixes and by phessler@ on an AMS-IX border router with 200+ session. Convergance time got quite a bit better. OK phessler@

Rename imsg_compose_parent and imsg_compose_rde to imsg_ctl_parent and imsg_ctl_rde since these function should only be used by the control code. Also switch ibuf_rde to ibuf_rde_ctl so that the control imsgs don't need to queue behind all the incoming bgp UPDATES. This speeds up 'bgpctl show' from taking minutes to a few seconds. The RDE was doing this since a very long time but it seems the SE was not adjusted. Yikes

Last bits of MPLS VPN support. Hook kernel routing tables and RIB together.
This adds a bit of new config to specify the mapping between an rdomain and
the BGP MPLS VPN instance, example:
rdomain 1 {
descr "CUSTOMER1"
rd 65003:1
import-target rt 65003:3
export-target rt 65003:1
depend on mpe0
network 192.168.224/24
}
The "depend on mpe0" is a but ugly but for now this is the quickest way to
figure out which interface bgp should use to insert the MPLS routes.
A big side-effect of this diff is that networks are now internally
distributed through kroute.c.
This needs some kernel changes that will follow hopefully soon.

Make bgpd 4-byte AS compatible. All internal representations of AS numbers are now 4-byte instead of the old 2-byte numbers. The only exception are communities because they can not be switched. The RDE will inflate and deflate the ASPATH and AGGREGATOR attributes on demand and create the NEW_ASPATH and NEW_AGGREGATOR field whenever needed. Both old and new stile sessions are supported and can be mixed. Currently new stile sessions with the 4-byte AS number capability turned on are only enabled if one of the AS numbers involved is a 4-byte one. This is based on an initial diff by Geoff Huston gih (at) apnic (dot) net Cleanup, testing and bug-fixes by myself (via AS 3.10). Currently mrt table dumps are producing incompatible output this will be fixed afterwards -- this diff is already big enough. "get it in if you think it is ready" henning@

Massiv rework of the control imsg flow. Main changes: - dedicated pipe between the SE and the RDE for control messages - restartable RB tree dumps in the RDE - queuing limits both in the SE and RDE The result is a dramatic decrease of memory consumption on operations like bgpctl show rib. Previously all messages where first stored in the RDE then passed to the SE where they got queued in case bgpctl was not fast enough. Now only a small number of messages is generated and passed to the SE and the SE has an additional limit instead of acting like an infinite buffer. Without this the bgpd on bgpd.networx.ch would not survive a single minute. looks good henning@

when a cloned peer goes back to IDLE state, don't remove him immediately but keep him around for some more time (an hour here). fixes an issue Arvid was reporting: when a cloned neighbor rejects our OPEN message due to capability negotiation (or missing implementation of those), we set a marker and retry without. However, if we remove the peer immediately, it gets freshly cloned on the next trial, with default settings, thus including capability negotiation, and thus failes again. this will also help with route flap dampening. ok claudio

move to a dynamically allocated struct pollfd array. we used a ststic one with OPEN_MAX entries, which is a rather arbitary limit as OPEN_MAX is _not_ the max # of open fds we can have, but just a default for that setting. in the same move we have to allocate the peer_l array, basically there for pfd-index to peer pointers to prevent peer list scans all time, dynamiccaly to. we overallocate a little and use that reserve until we have to realloc again later to prevent reallocs for every single control connection or a single flapping peer. help & ok claudio

if a peer follows the extremely misgiuded path that the RFCs just barely allow to send a NOTIFICATION and thus ternminating the session when it sees a capability it doesn't support (who would guess: zebra does so), parse the data section of the notifcication to find out what what capabilties it didn't like and do not advertise them the next time the session gets up. In case we get a notification about unsupported capabilities with an empty data part (don't ask for RFCs... and guess who does that), disable capabilty announcement alltogether. claudio ok

Big overhaul of the mrt code. Dumping of incomming bgp messages is now possible and dumping the (not yet) filtered updates works too. Per neighbor dumps are still missing. OK henning@

decouple the peer list from bgpd_config. so many parts of bgpd are not at all interested in the session specific peer structs... allows for some further cleaning

welcome, bgpd started by me some time ago with moral support from theo, the proceeded up to the point where the session engine worked correctly. claudio jeker joined then and did a lot of work in the RDE. it is not particulary usefull as application right now as parts are still missing but is imported to enable more people to work on it. status: BGP sessions get established fine, OPEN messages and then KEEPALIVEs exchanged etc. session FSM works fine; NOTIFICATIONs are handled fine, and all connection drops etc I provoked get handled fine. Incoming UPDATE messgages are parsed well and the data entered to the RIB, the decision process is not yet there, neither is outgoing UPDATEs or sync to the kernel routing table. not connected to the builds yet.
