2023-09-12Filter: The for loop uses the method system for type dispatchMaria Matejka
2023-09-12Removing unused terminals from filter configMaria Matejka
2023-09-12Filter: Methods reworkMaria Matejka
Methods can now be called as x.m(y), as long as x can have its type inferred in config time. If used as a command, it modifies the object, if used as a value, it keeps the original object intact. Also functions add(x,y), delete(x,y), filter(x,y) and prepend(x,y) now spit a warning and are considered deprecated. It's also possible to call a method on a constant, see filter/test.conf for examples like bgp_path = +empty+.prepend(1). Inside instruction definitions (filter/f-inst.c), a METHOD_CONSTRUCTOR() call is added, which registers the instruction as a method for the type of its first argument. Each type has its own method symbol table and filter parser switches between them based on the inferred type of the object calling the method. Also FI_CLIST_(ADD|DELETE|FILTER) instructions have been split to allow for this method dispatch. With type inference, it's now possible.
2023-09-12Uninitialized filter variables of path/[el]?clist types are now explicitly emptyMaria Matejka
2023-09-12Conf: config warnings show the file positionMaria Matejka
2023-09-12Filter: functions can and should have typed return valuesMaria Matejka
2023-09-12Filter/Conf: Method names have their own keyword hashMaria Matejka
To allow for future dynamic method definition, parsing method names is done via a dedicated keyword hash/scope.
2023-09-12Conf: Allowing conf scope to be explicitly read onlyMaria Matejka
2023-09-12Conf: Symbol manipulation gets its context explicitlyMaria Matejka
2023-09-12Filter: any lvalue can get its methods calledMaria Matejka
2023-09-12Filter: split out dot-notation methods to separate targetsMaria Matejka
This is just a preparationary refactoring to allow type-based method tables.
2023-09-12Conf: Keywords have their default symbolsMaria Matejka
This avoids unnecessary collapsed soft scopes caused by keyword symbol multiallocation.
2023-09-12Conf: Symbol hashes for all scopesMaria Matejka
This is a backport cherry-pick of commits 165156beeb2926472bbceca3c103aacc3f81a8cc cce974e8ea992d0e6d2f649eca7880b436d91d71 from the v3.0 branch as we need symbol hashes directly inside their scopes for more general usage than before.

2023-08-29BFD: Improve handling of AdminDownOndrej Zajicek
According to RFC 5882, system should not interpret the local or remote session state transition to AdminDown as failure. We followed that for the local session state but not for the remote session state (which just triggered a transition of the local state to Down). The patch fixes that. We do not properly generate AdminDown on our side, so the patch is relevant just for interoperability with other systems. Thanks to Sunnat Samadov for the bugreport.
2023-08-25Conf: Allow keywords to be redefined by user symbolsOndrej Zajicek
Most syntactic constructs in BIRD configuration (e.g. protocol options) are defined as keywords, which are distinct from symbols (user-defined names for protocols, variables, ...). That may cause backwards compatibility issue when a new feature is added, as it may collide with existing user names. We can allow keywords to be shadowed by symbols in almost all cases to avoid this issue. This replaces the previous mechanism, where shadowable symbols have to be explictly added to kw_syms.
2023-08-25Filter: Add separate instruction for uninitialized variable declarationOndrej Zajicek
The previous approach (use VOID constant for variable initialization) failed due to dynamic type check failure. Thanks to Alexander Zubkov <green@qrator.net> for the bugreport.
2023-08-25RPKI: Fix conflict in config grammarOndrej Zajicek
2023-08-25Nest: Fix missing bar in kw_symOndrej Zajicek
Thanks to Alexander Zubkov for the notice.
2023-08-24Doc: Document bytestring typeAlexander Zubkov
2023-08-24Doc: Document RAdv "custom option" configuration definitionAlexander Zubkov
2023-08-24Conf: Use nonterminal bytestring instead of BYTETEXTOndrej Zajicek
Nonterminal bytestring allows to provide expressions to be evaluated in places where BYTETEXT is used now: passwords, radv custom option. Based on the patch from Alexander Zubkov <green@qrator.net>, thanks!
2023-08-24Filter: Use more generic approach for intra-config expressionsAlexander Zubkov
Replace f_eval_int() function with a type-generic variant: cf_eval(). Implement similar fuction: cf_eval_int() via inline call to cf_eval().
2023-08-24Filter: Add bytestring typeAlexander Zubkov
- Rename BYTESTRING lexem to BYTETEXT, not to collide with 'bytestring' type name - Add bytestring type with id T_BYTESTRING (0x2c) - Add from_hex() filter function to create bytestring from hex string - Add filter test cases for bytestring type Minor changes by committer.
2023-08-24Lib: Add functions for reading and writing of bytestringsOndrej Zajicek
Based on patch from Alexander Zubkov, thanks!
2023-08-23Nest: Treat VRF interfaces as inside respective VRFsOndrej Zajicek
Despite not having defined 'master interface', VRF interfaces should be treated as being inside respective VRFs. They behave as a loopback for respective VRFs. Treating the VRF interface as inside the VRF allows e.g. OSPF to pick up IP addresses defined on the VRF interface. For this, we also need to tell apart VRF interfaces and regular interfaces. Extend Netlink code to parse interface type and mark VRF interfaces with IF_VRF flag. Based on the patch from Erin Shepherd, thanks!

2023-08-22BGP: Update RFC referenceOndrej Zajicek
RFC 5549 was obsoleted by RFC 8950.
2023-08-22BMP: Improve peer_down handlingOndrej Zajicek
Move all bmp_peer_down() calls to one place and make it synchronous with BGP session down, ensuring that BMP receives peer_down before route withdraws from flushing. Also refactor bmp_peer_down_() message generating code.
2023-08-21BMP: Use generic channel feed instead of direct walk over rtableOndrej Zajicek
Now we use rt_notify() and channels for both feed and notifications, in both import tables (pre-policy) and regular tables (post-policy). Remove direct walk in bmp_route_monitor_snapshot().
2023-08-21Nest: Use generic rte_announce() also for import tablesOndrej Zajicek
Remove special rte_announce_in(), so we can use generic rte_announce() for bot feed and notifications.
2023-08-18BMP: Fix route timestampsOndrej Zajicek
2023-08-18BMP: Refactor route monitoringOndrej Zajicek
- Manage BMP state through bmp_peer, bmp_stream, bmp_table structures - Use channels and rt_notify() hook for route announcements - Add support for post-policy monitoring - Send End-of-RIB even when there is no routes - Remove rte_update_in_notify() hook from import tables - Update import tables to support channels - Add bmp_hack (no feed / no flush) flag to channels
2023-08-01BMP: Remove useless bufferOndrej Zajicek
2023-08-01BMP: Simplify route monitoring hooksOndrej Zajicek
No need for *_begin(), *_commit(), and *_end() hooks. The hook *_notify() is sufficient for everything.
2023-06-30Fixed a typo in documentationAlexander Zubkov
The problem was the "/" symbol in the prefix mask that finished the formatting definition prematurely.
2023-06-26RAdv: Use new syntax for custom optionsAlexander Zubkov
And use WALK_LIST macro
2023-06-23RAdv: Add custom optionsAlexander Zubkov
Currently one can use only a predefined set of advertised options in RAdv protocol, which are supported by BIRD configuration. It would be convenient to be able to specify other possible options at least manually as a blob so one should not wait until it is supported in the code, released, etc. This idea is inspired by presentation by Ondřej Caletka at CSNOG, in which he noticed the lack of either PREF64 option or possibility to add custom options in various software. The patch makes it possible to define such options with the syntax: other type <num> <bytestring>
2023-06-23Add hex:XYZ syntax for short hex stringsAlexander Zubkov
Hexadecimal bytestring literals have minimal length to not collide with IP addresses or regular (hexadecimal) number literals. Allow to use shorter literals with explicit hex: prefix.
