2023-01-19Merge commit '140c534fb81d0e165b7d674e869c646455ed19d1' into thread-nextMaria Matejka
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.
2023-01-19Table prune routine doesn't walk over lists unless needed.Maria Matejka
If no channel is flushing, table prune doesn't walk over routes in nets and also doesn't walk over importing channel lists. This helps to alleviate the memory caching burdens a lot.
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.

2022-11-09Conf: Make 'configure check' command restrictedOndrej Zajicek
While it does not directly change BIRD state, it can trigger reading arbitrary files and eating significant memory.
2022-11-09Conf: Free stored old config before parsing new oneOndrej Zajicek
BIRD keeps a previous (old) configuration for the purpose of undo. The existing code frees it after a new configuration is successfully parsed during reconfiguration. That causes memory usage spikes as there are temporarily three configurations (old, current, and new). The patch changes it to free the old one before parsing the new one (as user already requested a new config). The disadvantage is that undo is not available after failed reconfiguration.

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.

2022-10-18Filter: Fix handling of variables in anonymous filtersOndrej Zajicek
Define scope for anonymous filters, and also explicitly distinguish block scopes and function/filter scopes instead of using anonymous / named distinction. Anonymous filters forgot to push scope, so variables for them were in fact defined in the top scope and therefore they shared a frame. This got broken after rework of variables, which assumed that there is a named scope for every function/filter.

2022-10-12Netlink: Parse onlink flag even on direct routesOndrej Zajicek
While onlink flag is meaningful only with explicit next hops, it can be defined also on direct routes. Parse it also in this case to avoid periodic updates of the same route. Thanks to Marcin Saklak for the bugreport.
