2022-09-07Next hop refactoring to allow for table lockingMaria Matejka
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.

It was necessary to update the code to match removal of rta, as well as existence of cached nested attribute lists.

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.)

2022-07-26Netlink: Restrict route replace for IPv6Ondrej Zajicek
Seems like the previous patch was too optimistic, as route replace is still broken even in Linux 4.19 LTS (but fixed in Linux 5.10 LTS) for: ip route add 2001:db8::/32 via fe80::1 dev eth0 ip route replace 2001:db8::/32 dev eth0 It ends with two routes instead of just the second. The issue is limited to direct and special type (e.g. unreachable) routes, the patch restricts route replace for cases when the new route is a regular route (with a next hop address).
2022-07-25Netlink: Simplify handling of IPv6 ECMP routesOndrej Zajicek
When IPv6 ECMP support first appeared in Linux kernel, it used different API than IPv4 ECMP. Individual next hops were updated and announced separately, instead of using RTA_MULTIPATH as in IPv4. This has several drawbacks and requires complex code to merge received notifications to one multipath route. When Linux came with IPv6 RTA_MULTIPATH support, the initial versions were somewhat buggy, so we kept using the old API for updates (splitting multipath routes to sequences of route updates), while accepting both old-style routes and RTA_MULTIPATH routes in scans / notifications. As IPv6 RTA_MULTIPATH support is here for a long time, this patch fully switches Netlink to the IPv6 RTA_MULTIPATH API and removes old complex code for handling individual next hop announces. The required Linux version is at least 4.11 for reliable operation. Thanks to Daniel Gröber for the original patch.
