2023-01-12Log message before abortingMike Crute
Log message before aborting due to watchdog timeout. We have to use async-safe write to debug log, as it is done in signal handler. Minor changes from committer.

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.

Introduce ipX_prefix_equal() and use it to simplify network matching code.

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).

2021-06-06Nest: Allow MAC algorithms to specify min/max key lengthToke Høiland-Jørgensen
Add min/max key length fields to the MAC algorithm description and validate configured keys before they are used.
2021-06-06Nest: Allow specifying security keys as hex bytes as well as stringsToke Høiland-Jørgensen
Add support for specifying a password in hexadecimal format, The result is the same whether a password is specified as a quoted string or a hex-encoded byte string, this just makes it more convenient to input high-entropy byte strings as MAC keys.
2021-06-06Lib: Add tests for blake2s and blake2bToke Høiland-Jørgensen
Import the blake2-kat.h header with test vector output from the blake reference implementation, and add tests to mac_test.c to compare the output of the Bird MAC algorithm implementations with that reference output. Since the reference implementation only has test vectors for the full output size, there are no tests for the smaller-sized output variants.
2021-06-06Lib: Add Blake2s and Blake2b hash functionsToke Høiland-Jørgensen
The Babel MAC authentication RFC recommends implementing Blake2s as one of the supported algorithms. In order to achieve do this, add the blake2b and blake2s hash functions for MAC authentication. The hashing function implementations are the reference implementations from blake2.net. The Blake2 algorithms allow specifying an arbitrary output size, and the Babel MAC spec says to implement Blake2s with 128-bit output. To satisfy this, we add two different variants of each of the algorithms, one using the default size (256 bits for Blake2s, 512 bits for Blake2b), and one using half the default output size. Update to BIRD coding style done by committer.
2021-06-06sysdep: Add wrapper to get random bytes - updateOndrej Zajicek (work)
Simplify the code and fix an issue with getentropy() return value.
2021-06-06sysdep: Add wrapper to get random bytesToke Høiland-Jørgensen
Add a wrapper function in sysdep to get random bytes, and required checks in configure.ac to select how to do it. The configure script tries, in order, getrandom(), getentropy() and reading from /dev/urandom.
2021-05-30Babel: Seqno requests are properly decoupled from neighbors when the ↵Maria Matejka
underlying interface disappears When an interface disappears, all the neighbors are freed as well. Seqno requests were anyway not decoupled from them, leading to strange segfaults. This fix adds a proper seqno request list inside neighbors to make sure that no pointer to neighbor is kept after free.

2021-05-18Flowspec: Label field should use numeric operator and not bitmask operatorOndrej Zajicek (work)
2021-05-18Flowspec: Do not use comma for bitmask operatorsOndrej Zajicek (work)
For numeric operators, comma is used for disjunction in expressions like "10, 20, 30..40". But for bitmask operators, comma is used for conjunction in a way that does not really make much sense. Use always explicit logical operators (&& and ||) to connect bitmask operators. Thanks to Matt Corallo for the bugreport.
2021-05-17Filter: Add MPLS label route attributeTrisha Biswas
Add support to set or read outgoing MPLS labels using filters. Currently this supports the addition of one label per route for the first next hop. Minor changes by committer.
2021-05-14Flowspec: Fix values for true/false operatorsOndrej Zajicek (work)
RFC 8955 is pretty clear that 000 is false and 111 is true.
2021-05-14Flowspec: Add code for conversion of flowspec parts to interval listsOndrej Zajicek (work)
Implement function flow_explicate_part() to convert flowspec numeric expressions to a simple list of (disjoint, sorted) intervals. That could be used in filters to build f_tree-based int-sets from them.
2021-04-12Lib: Fix handling of buffers in timestamp formattingOndrej Zajicek (work)
The code in tm_format_real_time() mixed up two buffers and their sizes, which may cause crash in MRT dumping code. Thanks to Piotr Wydrych for the bugreport.
