2021-11-22 | Split route table event into separate events | Maria Matejka | |
The former rt_event is dropped in favour of separate table events. This allows for selective corking of NHU and prune. | |||
2021-11-22 | Adding a generic cork mechanism for events | Maria Matejka | |
2021-11-22 | Converting the former BFD loop to a universal IO loop and protocol loop. | Maria Matejka | |
There is a simple universal IO loop, taking care of events, timers and sockets. Primarily, one instance of a protocol should use exactly one IO loop to do all its work, as is now done in BFD. Contrary to previous versions, the loop is now launched and cleaned by the nest/proto.c code, allowing for a protocol to just request its own loop by setting the loop's lock order in config higher than the_bird. It is not supported nor checked if any protocol changed the requested lock order in reconfigure. No protocol should do it at all. | |||
2021-11-22 | Moved BFD IO loop out of BFD as we want to use it as socket-io coroutine | Maria Matejka | |
2021-11-22 | Unified time for whole BIRD | Maria Matejka | |
In previous versions, every thread used its own time structures, effectively leading to different time in every thread and strange logging messages. The time processing code now uses global atomic variables to keep current time available for fast concurrent reading and safe updates. | |||
2021-11-22 | Debug messages with timestamps. | Maria Matejka | |
On most of current hardware, getting monotonic clock is fast enough to get it and write for each debug message. | |||

2021-11-22 | Type checking in SKIP_BACK macro | Maria Matejka | |
2021-11-22 | Route export is now asynchronous. | Maria Matejka | |
To allow for multithreaded execution, we need to break the import-export chain and buffer the exports before actually processing them. | |||
2021-11-22 | Better profylaction recursive route loops | Maria Matejka | |
In some specific configurations, it was possible to send BIRD into an infinite loop of recursive next hop resolution. This was caused by route priority inversion. To prevent priority inversions affecting other next hops, we simply refuse to resolve any next hop if the best route for the matching prefix is recursive or any other route with the same preference is recursive. Next hop resolution doesn't change route priority, therefore it is perfectly OK to resolve BGP next hops e.g. by an OSPF route, yet if the same (or covering) prefix is also announced by iBGP, by retraction of the OSPF route we would get a possible priority inversion. | |||
2021-11-22 | Special table hooks rectified. | Maria Matejka | |
* internal tables are now more standalone, having their own import and export hooks * route refresh/reload uses stale counter instead of stale flag, allowing to drop walking the table at the beginning * route modify (by BGP LLGR) is now done by a special refeed hook, reimporting the modified routes directly without filters | |||
2021-11-22 | Table import and export are now explicit hooks. | Maria Matejka | |
Channels have now included rt_import_req and rt_export_req to hook into the table instead of just one list node. This will (in future) allow for: * channel import and export bound to different tables * more efficient pipe code (dropping most of the channel code) * conversion of 'show route' to a special kind of export * temporary static routes from CLI The import / export states are also updated to the new algorithms. | |||

2021-11-09 | Route export: rejected by filter bitmap | Maria Matejka | |
If a route has been rejected by filter, store that information to avoid repeated export filter runs on rejected routes. | |||

2021-11-09 | Suppressed MRT unused static function warning | Maria Matejka | |
2021-11-09 | Split route data structure to storage (ro) / manipulation (rw) structures. | Maria Matejka | |
Routes are now allocated only when they are just to be inserted to the table. Updating a route needs a locally allocated route structure. Ownership of the attributes is also now not transfered from protocols to tables and vice versa but just borrowed which should be easier to handle in a multithreaded environment. | |||

2021-10-13 | IGP metric getter refactoring to protocol callback | Maria Matejka | |
Direct protocol hooks for IGP metric inside nest/rt-table.c make the protocol API unnecessarily complex. Instead, we use a proper callback. | |||
