2023-05-18Lib: Improve IP/net hashingOndrej Zajicek
Backport some changes from branch oz-parametric-hashes. Replace naive hash function for IPv6 addresses, fix hashing of VPNx (where upper half of RD was ignored), fix hashing of MPLS labels (where identity was used).
2023-03-06Net: Replace runtime checks with STATIC_ASSERT()Ondrej Zajicek
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 (?)
2020-03-03BGP: Handle flowspec rules without dst partOndrej Zajicek (work)
The RFC 5575 does not explicitly reject flowspec rules without dst part, it just requires dst part in validation procedure for feasibility, which we do not implement anyway. Thus flow without dst prefix is syntactically valid, but unfeasible (if feasibilty testing is done). Thanks to Alex D. for the bugreport.
2018-05-16Filter: Add support for src filter op to access SADR source prefixOndrej Zajicek (work)
The patch allows to use 'net.src' to access SADR source prefix from filters. Thanks to Toke Hoiland-Jorgensen for the original patch for srclen.
2018-02-13Add support for source-specific IPv6 routes to BIRD coreOndrej Zajicek (work)
This patch adds support for source-specific IPv6 routes to BIRD core. This is based on Dean Luga's original patch, with the review comments addressed. SADR support is added to network address parsing in confbase.Y and to the kernel protocol on Linux. Currently there is no way to mix source-specific and non-source-specific routes (i.e., SADR tables cannot be connected to non-SADR tables). Thanks to Toke Hoiland-Jorgensen for the original patch. Minor changes by Ondrej Santiago Zajicek.

2017-12-07Merge commit '98bb80a243b58c43453e9be69d19d0350286549c' into int-newOndrej Zajicek (work)
2017-04-18Check validity of dest w.r.t. net_typeOndrej Zajicek (work)
Allow to define static roa/flow routes without dest.
2017-03-22BGP: Support for MPLS labels and VPN SAFIOndrej Zajicek (work)
Basic support for SAFI 4 and 128 (MPLS labeled IP and VPN) for IPv4 and IPv6. Should work for route reflector, but does not properly handle originating routes with next hop self. Based on patches from Jan Matejka.

2017-02-20Several minor fixesOndrej Zajicek (work)
2016-12-22Netlink: MPLS routes in kernelJan Moskyto Matejka
Anyway, Bird is now capable to insert both MPLS routes and MPLS encap routes into kernel. It was (among others) needed to define platform-specific AF_MPLS to 28 as this constant has been assigned in the linux kernel. No support for BSD now, it may be added in the future.
2016-12-22MPLS: added net_addr_mpls variant of net_addrJan Moskyto Matejka
2016-12-07Basic flow specification support (RFC 5575)Ondrej Zajicek (work)
Add flow4/flow6 network and rt-table type and operations, config grammar and static protocol support. Squashed flowspec branch from Pavel Tvrdik.
2016-12-07Merge branch 'int-new-rpki-squashed' (early part) into int-newJan Moskyto Matejka
2016-12-07BGP redesignOndrej Zajicek (work)
Integrated and extensible BGP with generalized AFI handling, support for IPv4+IPv6 AFI and unicast+multicast SAFI.
2016-12-07Add `.asn' operator to all ROA prefixes in filtersPavel Tvrdik
Example: bird> eval (1.2.0.0/16 max 20 as 1234).asn 1234 Todo: Should be described in user docs
2016-05-12Miscellaneous minor fixesOndrej Zajicek (work)
2016-02-01Channels - explicit links between protocols and tablesOndrej Zajicek (work)
The patch adds support for channels, structures connecting protocols and tables and handling most interactions between them. The documentation is missing yet.
2016-01-14NET ROAx: add max_pxlen, fix formatPavel Tvrdík
2016-01-12NET ROAx more small changesPavel Tvrdík
- Remove `u8 src` from net_add_roaX - Add `u8 max_pxlen` to net_add_roaX - Add some missing macro and functions for ROA - Remove ASN from hash function for ROA Thanks to Ondrej Santiago Zajicek
2016-01-07Add NET ROA4/6 structuresPavel Tvrdík

2015-12-19Removed BITS_PER_IP_ADDRESS, MAX_PREFIX_LENGTH, BIRD_AFJan Moskyto Matejka
Explicit setting of AF_INET(6|) in IP socket creation. BFD set to listen on v6, without setting the V6ONLY flag to catch both v4 and v6 traffic. Squashing and minor changes by Ondrej Santiago Zajicek

2015-11-12Follow-up commit on integrated BIRDOndrej Zajicek (work)
Use net_addr for interface address prefixes, support net_addr in configuration parser.
2015-11-05Initial commit on integrated BIRDOndrej Zajicek (work)
New data types net_addr and variants (in lib/net.h) describing network addresses (prefix/pxlen). Modifications of FIB structures to handle these data types and changing everything to use these data types instead of prefix/pxlen pairs where possible. The commit is WiP, some protocols are not yet updated (BGP, Kernel), and the code contains some temporary scaffolding. Comments are welcome.
