2022-01-05Conf: Fix parsing full-length IPv6 addressesOndrej Zajicek (work)
Lexer expression for bytestring was too loose, accepting also full-length IPv6 addresses. It should be restricted such that colon is used between every byte or never. Fix the regex and also add some test cases for it. Thanks to Alexander Zubkov for the bugreport
2021-10-20Conf: Fix crash during shutdownOndrej Zajicek (work)
BIRD implements shutdown by reconfiguring to fake empty configuration. Such fake config structure is created from the last running config and shares some data, including symbol table. This allows access to (removed) routing tables and causes crash when 'show route' command is used during shutdown. Clean up symbol table, table list and links to default tables, so removed routing tables cannot be accessed during shutdown.

2021-06-06Nest: Allow specifying security keys as hex bytes as well as stringsToke Høiland-Jørgensen
Add support for specifying a password in hexadecimal format, The result is the same whether a password is specified as a quoted string or a hex-encoded byte string, this just makes it more convenient to input high-entropy byte strings as MAC keys.
2021-06-06sysdep: Add wrapper to get random bytes - updateOndrej Zajicek (work)
Simplify the code and fix an issue with getentropy() return value.
2021-06-06sysdep: Add wrapper to get random bytesToke Høiland-Jørgensen
Add a wrapper function in sysdep to get random bytes, and required checks in configure.ac to select how to do it. The configure script tries, in order, getrandom(), getentropy() and reading from /dev/urandom.
2021-05-18Flowspec: Label field should use numeric operator and not bitmask operatorOndrej Zajicek (work)
2021-02-10BGP: Add support for BGP hostname capabilityVincent Bernat
This is an implementation of draft-walton-bgp-hostname-capability-02. It is implemented since quite some time for FRR and in datacenter, this gives a nice output to avoid using IP addresses. It is disabled by default. The hostname is retrieved from uname(2) and can be overriden with "hostname" option. The domain name is never set nor displayed. Minor changes by committer.
2020-12-07Nest: Per-channel debug flagsOndrej Zajicek (work)
The patch add support for per-channel debug flags, currently just 'states', 'routes', and 'filters'. Flag 'states' is used for channel state changes, remaining two for routes passed through the channel. The per-protocol debug flags 'routes'/'filters' still enable reporting of routes for all channels, to keep existing behavior. The patch causes minor changes in some log messages.
2020-11-24Minor cleanups with cfg_allocz()Ondrej Zajicek (work)
Also fixes some more failed asserts due to add_tail().
2020-11-24Fix some failed asserts due to add_tail()Ondrej Zajicek (work)
When config structures are copied due to template application, we need to reset list node structure before calling add_tail(). Thanks to Mikael Magnusson for patches.
2020-11-12BFD: Better handling of BFD options in BGP configsOndrej Zajicek (work)
Merge multiple BFD option blocks in BGP configs instead of using the last one. That is necessary for proper handling of templates when BFD options are used both in a BGP template and in a BGP protocol derived from that template.
2020-11-08BFD: Allow per-request session optionsOndrej Zajicek (work)
BFD session options are configured per interface in BFD protocol. This patch allows to specify them also per-request in protocols requesting sessions (currently limited to BGP).
2020-05-01Lexer: strtoul shall never set endptr to NULL; it should be an errorMaria Matejka
2020-04-09Configuration strings are constant.Maria Matejka
This is merely a const propagation. There was no problem in there.

2019-11-03Support for address family constantsOndrej Zajicek (work)
We already had them defined on BGP level, but they are more general.

2019-06-30Nest: Add command to request graceful restartOndrej Zajicek (work)
When 'graceful down' command is entered, protocols are shut down with regard to graceful restart. Namely Kernel protocol does not remove routes and BGP protocol does not send notification, just closes the connection.

"linearize" instead. This is just a naming change.

2019-04-30BGP: Dynamic BGPOndrej Zajicek (work)
Support for dynamically spawning BGP protocols for incoming connections. Use 'neighbor range' to specify range of valid neighbor addresses, then incoming connections from these addresses spawn new BGP instances.

2019-02-25Custom number parser to speed up config parsingMaria Matejka
The glibc's generic parser is slow due to its versatility. Specialized parsers for base-10 and base-16 are much faster and we don't use other bases.

This should be revised, there are still ugly things in the filter API.

2019-02-20Filter: refactoring of instruction constructorsMaria Matejka
2019-02-20Filter refactoring: dropped the recursion from the interpreterMaria Matejka
This is a major change of how the filters are interpreted. If everything works how it should, it should not affect you unless you are hacking the filters themselves. Anyway, this change should make a huge improvement in the filter performance as previous benchmarks showed that our major problem lies in the recursion itself. There are also some changes in nest and protocols, related mostly to spreading const declarations throughout the whole BIRD and also to refactored dynamic attribute definitions. The need of these came up during the whole work and it is too difficult to split out these not-so-related changes.
2019-02-20Filter refactoring: Passing the resulting struct f_val as a pointer.Jan Maria Matejka
This also drops the multiplexing of errors with the f_val itself together with the T_RETURN f_val type flag.
2018-12-14Doc: Rename code documentation files back to DocOndrej Zajicek (work)
2018-12-06Custom route attributesMaria Matejka
For local route marking purposes, local custom route attributes may be defined. These attributes are seamlessly stripped after export filter to every real protocol like Kernel, BGP or OSPF, they however pass through pipes. We currently allow at most 256 custom attributes. This should be much faster than currently used bgp communities for marking routes.
