2022-09-08Table access is now locked.Maria Matejka
2022-09-08Table feed refactoring to allow for locking and unlockingMaria Matejka

2022-09-07Next hop refactoring to allow for table lockingMaria Matejka
2022-09-06Better profylaction recursive route loopsMaria 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.
2022-09-05Next hop update triggered at the very end of hostcache updateMaria Matejka
2022-09-05Exporter routine refactoring to allow for nicer table lockingMaria Matejka
2022-09-01Added an indirection to the export announcement routineMaria Matejka
There are performance reasons for this, mostly that we don't want to ping the table service routine with every import.
2022-09-01ROA subscriptions are also converted to export requests.Maria Matejka
By this, the requesting channels do the timers in their own loops, avoiding unnecessary synchronization when the central timer went off. This is of course less effective for now, yet it allows to easily implement selective reloads in future.
2022-09-01Flowspec revalidate notification converted to an export hookMaria Matejka
Instead of synchronous notifications, we use the asynchronous export framework to notify flowspec src route updates. This allows us to invoke flowspec revalidation without locking collisions.
2022-09-01Hostcache update notification converted to an export hookMaria Matejka
Instead of synchronous notifications, we use the asynchronous export framework to notify also hostcache updates. This allows us to do the hostcache update and the subsequent next hop update notification without locking collisions.
2022-09-01Miscellaneous refactoringMaria Matejka
2022-09-01Table debug is now a per-table setting and has categories.Maria Matejka
2022-09-01Default tables are not created unless actually used.Maria Matejka
This allows for setting default table values at the beginning of config file before "master4" and "master6" tables are initialized.
2022-08-30Tables: Requesting prune only after export cleanupMaria Matejka
We can't free the network structures before the export has been cleaned up, therefore it makes more sense to request prune only after export cleanup. This change also reduces prune calls on table shutdown.

2022-08-03Merge commit '97476e00' into thread-nextMaria Matejka
Had to fix route source locking inside BGP export table as we need to keep the route sources properly allocated until even last BGP pending update is sent out, therefore the export table printout is accurate.

Replacing the old 3.0-alpha0 cork mechanism with another one inside the routing table. This version should be simpler and also quite clear what it does, why and when.
2022-08-02Revert "Split route table event into separate events"Maria Matejka
This reverts commit 445eeaf3df126af2c7b61e71c4f08a583eb4fa60.
2022-08-02Revert "Table cork: Stop creating updates when there are too many pending."Maria Matejka
This reverts commit 3b20722a1fc777c27ab2e0451d0ea3fee7fa81a2.
2022-08-02Also next hop update routines are corking themselves when congestion is detectedMaria Matejka
2022-08-02BGP: respecting table corkMaria Matejka
2022-08-02Route table cork: Indicate whether the export queues are congested.Maria Matejka
These routines detect the export congestion (as defined by configurable thresholds) and propagate the state to readers. There are no readers for now, they will be added in following commits.
2022-08-02Introducing basic RCU primitives for lock-less shared data structuresMaria Matejka
2022-08-01Fixed main birdloop init in unit testsMaria Matejka
Some unit tests weren't initializing the birdloop, trying to write the birdloop ping into stdin. Fixed this and also forced stdin close on startup of every test just to be sure that CI and local build behave the same in this. (CI was failing on this while local build not.)
