2023-01-19Decoupling loops from threads to allow fixed thread countMaria Matejka
On large configurations, too many threads would spawn with one thread per loop. Therefore, threads may now run multiple loops at once. The thread count is configurable and may be changed during run. All threads are spawned on startup. This change helps with memory bloating. BIRD filters need large temporary memory blocks to store their stack and also memory management keeps its hot page storage per-thread. Known bugs: * Thread autobalancing is not yet implemented. * Low latency loops are executed together with standard loops.
2023-01-19CLI closing fix when its action is run asynchronously.Maria Matejka
Some CLI actions, notably "show route", are run by queuing an event somewhere else. If the user closes the socket, in case such an action is being executed, the CLI must free the socket immediately from the error hook but the pool must remain until the asynchronous event finishes and cleans everything up.

2022-11-03Page allocator: Fixed minor bugs and added commentaryMaria Matejka
2022-11-02Memory pages are not munmapped, instead we just madvise()Maria Matejka
Memory unmapping causes slow address space fragmentation, leading in extreme cases to failing to allocate pages at all. Removing this problem by keeping all the pages allocated to us, yet calling madvise() to let kernel dispose of them. This adds a little complexity and overhead as we have to keep the pointers to the free pages, therefore to hold e.g. 1 GB of 4K pages with 8B pointers, we have to store 2 MB of data.

2022-09-27KRT: Fix route learningMaria Matejka
This is a reimplementation of commit 0f2be469f897b6d9f925563bbf522438c83522ea by Alexander Zubkov. In the master branch, changes in commit eb937358 broke setting of channel preference for alien routes learned during scan. The preference was set only for async routes. The original solution is extended here to accomodate for v3 specifics.
2022-09-27KRT: Fix setting default preferenceAlexander Zubkov
Changes in commit eb937358 broke setting of channel preference for alien routes learned during scan. The preference was set only for async routes. Move common attribute processing part of functions krt_learn_async() and krt_learn_async() to a separate function to have only one place for such changes.

2022-07-24KRT: Scan routing tables separetely on linux to avoid congestionOndrej Zajicek
Remove compile-time sysdep option CONFIG_ALL_TABLES_AT_ONCE, replace it with runtime ability to run either separate table scans or shared scan. On Linux, use separate table scans by default when the netlink socket option NETLINK_GET_STRICT_CHK is available, but retreat to shared scan when it fails. Running separate table scans has advantages where some routing tables are managed independently, e.g. when multiple routing daemons are running on the same machine, as kernel routing table modification performance is significantly reduced when the table is modified while it is being scanned. Thanks Daniel Gröber for the original patch and Toke Høiland-Jørgensen for suggestions.

2022-07-11Dropped the internal kernel protocol table for learnt routes.Maria Matejka
The learnt routes are now pushed all into the connected table, not only the best one. This shouldn't do any damage in well managed setups, yet it should be noted that it is a change of behavior. If anybody misses a feature which they implemented by misusing this internal learn table, let us know, we'll consider implementing it in a better way.

Soft scopes are anonymous scopes that most likely do not contain any symbol, so allocating regular scope is postponed when it is really needed.

Passing protocol to preexport was in fact a historical relic from the old times when channels weren't a thing. Refactoring that to match current extensibility needs.
