2019-03-14Nest: Update handling of temporary attributesOndrej Zajicek (work)
The temporary atttributes are no longer removed by ea_do_prune(), but they are undefined by store_tmp_attrs() protocol hooks. This fixes several bugs where temporary attributes were removed when they should not or not removed when they should be. The flag EAF_TEMP is no longer needed and was removed. Update all protocol make_tmp_attrs() / store_tmp_attrs() hooks to use helper functions and to handle unset attributes properly. Also fix some related bugs like improper handling of empty eattr list.
2018-11-28Nest: Do not hard-reset interface when preferred address is changedOndrej Zajicek (work)
Modify protocols to use preferred address change notification instead on depending on hard-reset of interfaces in that case, and remove hard-reset in that case. This avoids issue when e.g. IPv6 protocol restarts interface when IPv4 preferred address changed (as hard-reset is unavoidable and common for whole iface). The patch also fixes a bug when removing last address does not send preferred address change notification.
2018-06-27Nest: Neighbor cache cleanupsOndrej Zajicek (work)
Simplify neighbor cache code, fix several minor bugs, and improve handling of ONLINK flag.
2018-05-30Nest: Removing separate tmpa from route propagationJan Maria Matejka
This is a fundamental change of an original (1999) concept of route processing inside BIRD. During import/export, there was a temporary ea_list created which was to be used instead of the another one inside the route itself. This led to some confusion, quirks, and strange filter code that handled extended route attributes. Dropping it now. The protocol interface has changed in an uniform way -- the `struct ea_list *attrs` argument has been removed from store_tmp_attrs(), import_control(), rt_notify() and get_route_info().
2018-05-29Protocol: Introducing an enum protocol_classJan Maria Matejka
This supersedes the EAP_* constants.
2018-05-24Do not initialize route metrics in import_control hookOndrej Zajicek (work)
During route export, the receiving protocol often initialized route metrics to default value in its import_control hook before export filter was executed. This is inconsistent with the expectation that an export filter would process the same route as one in the routing table and it breaks setting these metrics before (e.g. for static routes directly in static protocol). The patch removes the initialization of route metrics in import_control hook, the default values are already handled in rt_notify hook called after export filters. The patch also changed the behavior of OSPF to keep metrics when a route is reannounced between OSPF instances (to be consistent with other protocols) and the behavior when both ospf_metric1 and ospf_metric2 are specified (to have more expected behavior).
2018-01-09Nest: Allow modification of channels inherited from templatesOndrej Zajicek (work)
Multiple definitions of same channels are forbidden, but inherited channel can be redefined. In such case channel options are merged.
2017-12-07Timers: Revert temporary names and remove old timer.hOndrej Zajicek (work)
2017-12-07RIP: Update to new timersOndrej Zajicek (work)
2017-12-07Timers: Replace old timers with microsecond timersOndrej Zajicek (work)
The old timer interface is still kept, but implemented by new timers. The plan is to switch from the old inteface to the new interface, then clean it up.
2017-12-07Nest: Maintain separate IPv4, IPv6 and LLv6 preferred addressesOndrej Zajicek (work)
Also redesign preferred address selection and update protocols to use appropriate preferred address. Based on a previous work by Jan Maria Matejka.
2017-05-23Minor cleanups and fixesOndrej Zajicek (work)
2017-02-20Several minor fixesOndrej Zajicek (work)
2016-12-22Removing (struct rta)->cast. Never used.Jan Moskyto Matejka
2016-12-22Merged multipath and single-path data structures.Jan Moskyto Matejka
Dropped struct mpnh and mpnh_*() Now struct nexthop exists, nexthop_*(), and also included struct nexthop into struct rta. Also converted RTD_DEVICE and RTD_ROUTER to RTD_UNICAST. If it is needed to distinguish between these two cases, RTD_DEVICE is equivalent to IPA_ZERO(a->nh.gw), RTD_ROUTER is then IPA_NONZERO(a->nh.gw). From now on, we also explicitely want C99 compatible compiler. We assume that this 20-year norm should be known almost everywhere.

2016-11-02RIP: Use message authentication interfaceOndrej Zajicek (work)
Based on former commit from Pavel Tvrdik
2016-11-01Build: switch on -Wextra, get rid of most of the warningsJan Moskyto Matejka
There are several unresolved -Wmissing-field-initializers on older versions of GCC than 5.1, all of them false positive.
2016-09-14Nest: Keep multipath next hops sortedOndrej Zajicek (work)
2016-04-08Route update: move table lookup from protocols into rte_update2().Jan Moskyto Matejka
Many protocols do almost the same when creating a rte_update request before calling rte_update2(). This commit should simplify the protocol side of the route-creation routine.
2016-04-07Channelize: rt_notify arg conversion table -> channelJan Moskyto Matejka
2016-02-01Channels - explicit links between protocols and tablesOndrej Zajicek (work)
The patch adds support for channels, structures connecting protocols and tables and handling most interactions between them. The documentation is missing yet.
2015-12-21Modify FIB_WALK() and FIB_ITERATE() to work with new FIB codeOndrej Zajicek (work)
Returned user data pointers have offset relative to fib_node.
2015-12-21Follow-up work on integrationOndrej Zajicek (work)
2015-11-05Initial commit on integrated BIRDOndrej Zajicek (work)
New data types net_addr and variants (in lib/net.h) describing network addresses (prefix/pxlen). Modifications of FIB structures to handle these data types and changing everything to use these data types instead of prefix/pxlen pairs where possible. The commit is WiP, some protocols are not yet updated (BGP, Kernel), and the code contains some temporary scaffolding. Comments are welcome.
2015-10-05Major RIP redesignOndrej Zajicek (work)
The new RIP implementation fixes plenty of old bugs and also adds support for many new features: ECMP support, link state support, BFD support, configurable split horizon and more. Most options are now per-interface.
2015-02-21Store protocol config size inside protocol structureOndrej Zajicek
Make proto_config_new() use this info instead of supplied size. Thanks to Alexander V. Chernikov for the patch.

2014-10-24Integrated IP functions.Ondrej Zajicek
2014-05-18IPv4/IPv6 integrated socket code.Ondrej Zajicek
2014-02-06Many changes in I/O and OSPF sockets and packet handling.Ondrej Zajicek
I/O: - BSD: specify src addr on IP sockets by IP_HDRINCL - BSD: specify src addr on UDP sockets by IP_SENDSRCADDR - Linux: specify src addr on IP/UDP sockets by IP_PKTINFO - IPv6: specify src addr on IP/UDP sockets by IPV6_PKTINFO - Alternative SKF_BIND flag for binding to IP address - Allows IP/UDP sockets without tx_hook, on these sockets a packet is discarded when TX queue is full - Use consistently SOL_ for socket layer values. OSPF: - Packet src addr is always explicitly set - Support for secondary addresses in BSD - Dynamic RX/TX buffers - Fixes some minor buffer overruns - Interface option 'tx length' - Names for vlink pseudoifaces (vlinkX) - Vlinks use separate socket for TX - Vlinks do not use fixed associated iface - Fixes TTL for direct unicast packets - Fixes DONTROUTE for OSPF sockets - Use ifa->ifname instead of ifa->iface->name

2013-06-25Implements TTL security for OSPF and RIP.Ondrej Zajicek
Interfaces for OSPF and RIP could be configured to use (and request) TTL 255 for traffic to direct neighbors. Thanks to Simon Dickhoven for the original patch for RIPng.
2013-06-24Better packet priority and traffic class handling.Ondrej Zajicek
Implements support for IPv6 traffic class, sets higher priority for OSPF and RIP outgoing packets by default and allows to configure ToS/DS/TClass IP header field and the local priority of outgoing packets.
