2021-12-01No memory unmapping when shutting downMaria Matejka
All the memory is just freed implicitly on exit, no need for page-by-page unmapping.

2021-12-01Page allocator moved from pools to IO loops.Maria Matejka
The resource pool system is highly hierarchical and keeping spare pages in pools leads to unnecessarily complex memory management. Loops have a flat hiearchy, at least for now, and it is therefore much easier to keep care of pages, especially in cases of excessive virtual memory fragmentation.
2021-11-30For safer memory allocations, resources are bound to loops.Maria Matejka
Also all loops have their basic resource pool for allocations which are auto-freed when the loop is stopping.
2021-11-27Memory statistics split into Effective and OverheadMaria Matejka
This feature is intended mostly for checking that BIRD's allocation strategies don't consume much memory space. There are some cases where withdrawing routes in a specific order lead to memory fragmentation and this output should give the user at least a notion of how much memory is actually used for data storage and how much memory is "just allocated" or used for overhead. Also raising the "system allocator overhead estimation" from 8 to 16 bytes; it is probably even more. I've found 16 as a local minimum in best scenarios among reachable machines. I couldn't find any reasonable method to estimate this value when BIRD starts up. This commit also fixes the inaccurate computation of memory overhead for slabs where the "system allocater overhead estimation" was improperly added to the size of mmap-ed memory.

2021-11-22Route attribute cache is now lockless on read / clone.Maria Matejka
Lots of time was spent locking when accessing route attribute cache. This overhead should be now reduced to a minimum.

2021-11-22Keeping un-unmmappable pages until they can be reusedMaria Matejka
On Linux, munmap() may fail with ENOMEM when virtual memory is too fragmented. Working this around by just keeping such blocks for future use.
2021-11-22Pipe runs in parallel.Maria Matejka
2021-11-22Routing tables now have their own loops.Maria Matejka
This basically means that: * there are some more levels of indirection and asynchronicity, mostly in cleanup procedures, requiring correct lock ordering * all the internal table operations (prune, next hop update) are done without blocking the other parts of BIRD * the protocols may get their own loops very soon
