2022-05-04Conf: Allowing keyword redefinitionMaria Matejka
Some tokens are both keywords and symbols. For now, we allow only specific keywords to be redefined; in future, more of the keywords may be added to this category. The redefinable keywords must be specified in any .Y file as follows: toksym: THE_KEYWORD ; See proto/bgp/config.Y for an example. Also dropped a lot of unused terminals.
2022-05-04Explicit definition structures of route attributesMaria Matejka
Changes in internal API: * Every route attribute must be defined as struct ea_class somewhere. * Registration of route attributes known at startup must be done by ea_register_init() from protocol build functions. * Every attribute has now its symbol registered in a global symbol table defined as SYM_ATTRIBUTE * All attribute ID's are dynamically allocated. * Attribute value custom formatting hook is defined in the ea_class. * Attribute names are the same for display and filters, always prefixed by protocol name. Also added some unit testing code for filters with route attributes.
2022-05-04Unified attribute and filter typesMaria Matejka
This commit removes the EAF_TYPE_* namespace completely and also for route attributes, filter-based types T_* are used. This simplifies fetching and setting route attributes from filters. Also, there is now union bval which serves as an universal value holder instead of private unions held separately by eattr and filter code.
2018-06-26Config: Dropping CF_ADDTO.Jan Maria Matejka
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().

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.

2016-08-30KRT: Forbid path merging on BSDOndrej Zajicek (work)
We support ECMP routes only on Linux. Exported routes are checked in krt_capable(), but a route generated during path merging avoids this check.
2016-05-10Build system reworked to one global Makefile with includes and no nestingJan Moskyto Matejka
Also removed the lib-dir merging with sysdep. Updated #include's accordingly. Fixed make doc on recent Debian together with moving generated doc into objdir. Moved Makefile.in into root dir Retired all.o and birdlib.a Linking the final binaries directly from all the .o files.
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.
2015-12-24Follow-up work on integrationOndrej Zajicek (work)
2015-12-21Follow-up work on integrationOndrej Zajicek (work)
Contains some patches from Jan Moskyto Matejka
2015-11-12Follow-up commit on integrated BIRDOndrej Zajicek (work)
Use net_addr for interface address prefixes, support net_addr in configuration parser.
2015-06-08BGP multipath supportOndrej Zajicek
Kernel option 'merge paths' allows to merge routes exported to kernel protocol (currently BGP and static routes) to multipath routes.
2014-03-20BGP graceful restart support.Ondrej Zajicek
Also significant core protocol state changes needed for that, global graceful restart recovery state and kernel proto support for recovery.
2012-04-30Cleanup in sysdep KRT code, part 1.Ondrej Zajicek
OS-dependent functions renamed to be more consistent, prepared to merge krt-set and krt-scan headers. Name changes: struct krt_if_params -> struct kif_params struct krt_if_status -> struct kif_status struct krt_set/scan_params -> struct krt_params struct krt_set/scan_status -> struct krt_status krt_if_params_same -> kif_sys_reconfigure krt_if_copy_params -> kif_sys_copy_config krt_set/scan_params_same -> krt_sys_reconfigure krt_set/scan_copy_params -> krt_sys_copy_config krt_if_scan -> kif_do_scan krt_set_notify -> krt_do_notify krt_scan_fire -> krt_do_scan krt_if_ -> kif_sys_ krt_scan_ -> krt_sys_ krt_set_ -> krt_sys_
2012-03-23Adds krt_metric linux route attribute.Ondrej Zajicek
2012-03-23Adds krt_source route attribute.Ondrej Zajicek
Thanks Jeremie Dimino for the original patch.
2012-01-24Assign default protocol preference via proto_config_new().Ondrej Zajicek
The patch from Alexander V. Chernikov.
2011-11-07Implements protocol templates.Ondrej Zajicek
Based on the patch from Alexander V. Chernikov. Extended to support almost all protocols. Uses 'protocol bgp NAME from TEMPLATE { ... }' syntax.
2010-04-04Restrict export of device routes to the kernel protocol.Ondrej Zajicek
In usual configuration, such export is already restricted with the aid of the direct protocol but there are some races that can circumvent it. This makes it harder to break kernel device routes. Also adds an option to disable this restriction.
2009-05-29Implements primary address selection base on 'primary' option.Ondrej Zajicek
2009-05-29Add 'primary' configuration option.Ondrej Zajicek
2000-05-08Use preferences properly.Martin Mares
2000-04-28Split CF_HDR section to CF_HDR (only includes) and CF_DEFINES (defines,Martin Mares
C declarations etc.).
2000-01-17Separated `official protocol names' used in status dumps from name templatesMartin Mares
used for automatic generation of instance names. protocol->name is the official name protocol->template is the name template (usually "name%d"), should be all lowercase. Updated all protocols to define the templates, checked that their configuration grammar includes proto_name which generates the name and interns it in the symbol table.
1999-08-03Kernel route syncer supports multiple tables.Martin Mares
The changes are just too extensive for lazy me to list them there, but see the comment at the top of sysdep/unix/krt.c. The code got a bit more ifdeffy than I'd like, though. Also fixed a bunch of FIXME's and added a couple of others. :)
1999-04-03More changes to the kernel syncer.Martin Mares
o Now compatible with filtering. o Learning of kernel routes supported only on CONFIG_SELF_CONSCIOUS systems (on the others it's impossible to get it semantically correct). o Learning now stores all of its routes in a separate fib and selects the ones the kernel really uses for forwarding packets. o Better treatment of CONFIG_AUTO_ROUTES ports. o Lots of internal changes.
1999-03-26Moved to a much more systematic way of configuring kernel protocols.Martin Mares
o Nothing is configured automatically. You _need_ to specify the kernel syncer in config file in order to get it started. o Syncing has been split to route syncer (protocol "Kernel") and interface syncer (protocol "Device"), device routes are generated by protocol "Direct" (now can exist in multiple instances, so that it will be possible to feed different device routes to different routing tables once multiple tables get supported). See doc/bird.conf.example for a living example of these shiny features.
1999-03-03Rewrote the kernel syncer. The old layering was horrible.Martin Mares
The new kernel syncer is cleanly split between generic UNIX module and OS dependent submodules: - krt.c (the generic part) - krt-iface (low-level functions for interface handling) - krt-scan (low-level functions for routing table scanning) - krt-set (low-level functions for setting of kernel routes) krt-set and krt-iface are common for all BSD-like Unices, krt-scan is heavily system dependent (most Unices require /dev/kmem parsing, Linux uses /proc), Netlink substitues all three modules. We expect each UNIX port supports kernel routing table scanning, kernel interface table scanning, kernel route manipulation and possibly also asynchronous event notifications (new route, interface state change; not implemented yet) and build the KRT protocol on the top of these primitive operations.
1999-02-05Synced kernel interface to new interface.Martin Mares
1998-12-06Kernel syncer is now configurable. It will probably need some moreMartin Mares
options, but at least basic tuning is possible now.
