2020-02-21RIP: Demand circuit support (RFC 2091)Ondrej Zajicek (work)
2020-01-07KRT: Improve syncer code to avoid using temporary data in rtableOndrej Zajicek (work)
The old code stored route verdicts and temporary routes directly in rtable. The new code do not store received routes (it immediately compares them with exported routes and resolves conflicts) and uses internal bitmap to keep track of which routes were received and which needs to be reinstalled. By not putting 'invalid' temporary routes to rtable, we keep rtable in consistent state, therefore scan no longer needs to be atomic operation and could be splitted to multiple events.
2019-01-31Nest: FIB rehash values tweaked for better performanceMaria Matejka
2018-12-04Route table max hash size raised to 2^24.Jan Maria Matejka
This is still OK for everybody to fit into RAM and also probably enough to keep a little collision rate for full BGP table.
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.

2015-12-20Nest: Reimplement fib_route() and add some constsOndrej Zajicek (work)
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.
2015-10-05Major RIP redesignOndrej Zajicek (work)
The new RIP implementation fixes plenty of old bugs and also adds support for many new features: ECMP support, link state support, BFD support, configurable split horizon and more. Most options are now per-interface.

I've changed the init callback type to a typedef to work around a bug in kernel-doc I'm too lazy to hunt now.

2000-03-31Include "lib/string.h" instead of <string.h>. It should give us bzero()Martin Mares

1998-12-20die() -> bug() where appropriate.Martin Mares
1998-12-20Rewrote fib functions to make them insert/delete/asynchronous-walk safe.Martin Mares
This is implemented in a way similar to lib/slists.h, but it took some more effort to make rehashing not disturb the readers. We do it by just taking _highest_ k bits of ipa_hash as our hash value and sorting each box by whole ipa_hash(). Consult FIB_ITERATE_* macros in nest/route.h. Implemented fib_check() debugging function and also rewrote the rehashing algorithm to use better thresholds and not to waste time by rehashing forth and back.
1998-11-29Renamed `DEBUG' symbol to `DEBUGGING' to prevent collisions with tokenMartin Mares
