2022-05-04Enforcing certain data structure explicit paddings.Maria Matejka
Implicit paddings have undefined values in C. We want the eattr blocks to be comparable by memcmp and eattrs settable directly by structrure literals. This check ensures that all paddings in eattr and bval are explicit and therefore zeroed in all literals.

2022-05-04Unified attribute and filter typesMaria Matejka
This commit removes the EAF_TYPE_* namespace completely and also for route attributes, filter-based types T_* are used. This simplifies fetching and setting route attributes from filters. Also, there is now union bval which serves as an universal value holder instead of private unions held separately by eattr and filter code.

2022-03-16Lib: Allow use of 240.0.0.0/4 as a private rangeOndrej Zajicek (work)
There were several requests to allow use of 240.0.0.0/4 as a private range, and Linux kernel already allows such routes, so perhaps we can allow that too. Thanks to Vincent Bernat and others for suggestion and patches.

2022-02-07Lib: Update alignment of slabsOndrej Zajicek (work)
Alignment of slabs should be at least sizeof(ptr) to avoid unaligned pointers in slab structures. Fixme: Use proper way to choose alignment for internal allocators.

2022-02-06Nest: Attach prefix trie to rtable for faster LPM and interval queriesOndrej Zajicek (work)
Attach a prefix trie to IP/VPN/ROA tables. Use it for net_route() and net_roa_check(). This leads to 3-5x speedups for IPv4 and 5-10x speedup for IPv6 of these calls. TODO: - Rebuild the trie during rt_prune_table() - Better way to avoid trie_add_prefix() in net_get() for existing tables - Make it configurable (?)
2022-01-08IO: Support nonlocal bind in socket interfaceAlexander Zubkov
Add option to socket interface for nonlocal binding, i.e. binding to an IP address that is not present on interfaces. This behaviour is enabled when SKF_FREEBIND socket flag is set. For Linux systems, it is implemented by IP_FREEBIND socket flag. Minor changes done by commiter.
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.

2021-10-13Multipage allocationMaria Matejka
We can also quite simply allocate bigger blocks. Anyway, we need these blocks to be aligned to their size which needs one mmap() two times bigger and then two munmap()s returning the unaligned parts. The user can specify -B <N> on startup when <N> is the exponent of 2, setting the block size to 2^N. On most systems, N is 12, anyway if you know that your configuration is going to eat gigabytes of RAM, you are almost forced to raise your block size as you may easily get into memory fragmentation issues or you have to raise your maximum mapping count, e.g. "sysctl vm.max_map_count=(number)".

2021-09-25Filter: Faster prefix setsOndrej Zajicek (work)
Use 16-way (4bit) branching in prefix trie instead of basic binary branching. The change makes IPv4 prefix sets almost 3x faster, but with more memory consumption and much more complicated algorithm. Together with a previous filter change, it makes IPv4 prefix sets about ~4.3x faster and slightly smaller (on my test data).
