13c10ee062 Doc: Fix datetime format for password entries
In BIRD 1, we used DD-MM-YYYY, while in BIRD 2 we switched to the usual
format YYYY-MM-DD.

Thanks to Janne Pisilä for the bugreport.

c3335b5044 Static: Allow to define both nexthop and interface
Allow to define both nexthop and interface using iproute2-like syntax,
e.g.: route 10.0.0.0/16 via 10.1.0.1 dev "eth0";

Now we can avoid to use link-local scope hack (e.g. 10.1.0.1%eth0)
for cases where both nexthop and interface have to be defined.

Thanks to Marcin Saklak for the suggestion.

f42c118aa7 Basic route aggregation
Add a new protocol offering route aggregation.

User can specify list of route attributes in the configuration file and
run route aggregation on the export side of the pipe protocol. Routes are
sorted and for every group of equivalent routes new route is created and
exported to the routing table. It is also possible to specify filter
which will run for every route before aggregation.

Furthermore, it will be possible to set attributes of new routes
according to attributes of the aggregated routes.

This is a work in progress.

Original work by Igor Putovny, subsequent cleanups and finalization by
Maria Matejka.

This is a split-commit of the neighboring aggregator branch
with a bit improved lvalue handling, to have easier merge into v3.

fc9d471b36 Filter: Methods rework
Methods can now be called as x.m(y), as long as x can have its type
inferred in config time. If used as a command, it modifies the object,
if used as a value, it keeps the original object intact.

Also functions add(x,y), delete(x,y), filter(x,y) and prepend(x,y) now
spit a warning and are considered deprecated.

It's also possible to call a method on a constant, see filter/test.conf
for examples like bgp_path = +empty+.prepend(1).

Inside instruction definitions (filter/f-inst.c), a METHOD_CONSTRUCTOR()
call is added, which registers the instruction as a method for the type
of its first argument. Each type has its own method symbol table and
filter parser switches between them based on the inferred type of the
object calling the method.

Also FI_CLIST_(ADD|DELETE|FILTER) instructions have been split to allow
for this method dispatch. With type inference, it's now possible.

f08abcb8dd Babel: Add support for the RTT extension
This adds support to the Babel protocol for the RTT extension specified
in draft-ietf-babel-rtt-extension. While this extension is not yet at the
RFC stage, it is one of the more useful extensions to Babel[0], so it
seems worth having in Bird as well.

The extension adds timestamps to Hello and IHU TLVs and uses these to
compute an RTT to each neighbour. An extra per-neighbour cost is then
computed from the RTT based on a minimum and maximum interval and cost
value specified in the configuration. The primary use case for this is
improving routing in a geographically distributed tunnel-based overlay
network.

The implementation follows the babeld implementation when picking
constants and default configuration values. It also uses the same RTT
smoothing algorithm as babeld, and follows it in adding a new 'tunnel'
interface type which enables RTT by default.

eecc3f02e4 Babel: Implement IPv4 via IPv6 extension (RFC 9229)
The patch implements an IPv4 via IPv6 extension (RFC 9229) to the Babel
routing protocol (RFC 8966) that allows annoncing routes to an IPv4
prefix with an IPv6 next hop, which makes it possible for IPv4 traffic
to flow through interfaces that have not been assigned an IPv4 address.

The implementation is compatible with the current Babeld version.

84c298465f Decoupling loops from threads to allow fixed thread count
On large configurations, too many threads would spawn with one thread
per loop. Therefore, threads may now run multiple loops at once. The
thread count is configurable and may be changed during run. All threads
are spawned on startup.

This change helps with memory bloating. BIRD filters need large
temporary memory blocks to store their stack and also memory management
keeps its hot page storage per-thread.

Known bugs:
* Thread autobalancing is not yet implemented.
* Low latency loops are executed together with standard loops.

7144c9ca46 Filter: Allow setting the 'onlink' route attribute in filters
Add static route attribute to set onlink flag for route next hop. Can be
used to build a dynamically routed IP-in-IP overlay network. Usage:

     ifname = "tunl0";
     onlink = true;
     gw = bgp_next_hop;

e48f898fda Doc: Document issue with import tables
The import table does not work reliably together with re-evaluation of
routes due to recursive next hops or flowspec validation. We will at
least document that here, as import tables are completely redesigned and
this issue is fixed in BIRD 3.x branch.

3859e4efc1 BGP: Improve handling of hold and keepalive timers
The effective keepalive time now scales relative to the negotiated
hold time, to maintain proportion between the keepalive time and the
hold time. This avoids issues when both keepalive and hold times
were configured, the hold time was negotiated to a smaller value,
but the keepalive time stayed the same.

Add new options 'min hold time' and 'min keepalive time', which reject
session attempts with too small hold time.

Improve validation of config options an their documentation.

Thanks to Alexander Zubkov and Sergei Goriunov for suggestions.

371eb49043 Conf: Free stored old config before parsing new one
BIRD keeps a previous (old) configuration for the purpose of undo. The
existing code frees it after a new configuration is successfully parsed
during reconfiguration. That causes memory usage spikes as there are
temporarily three configurations (old, current, and new). The patch
changes it to free the old one before parsing the new one (as user
already requested a new config). The disadvantage is that undo is
not available after failed reconfiguration.

8f79e6b93e BGP: Add option 'next hop prefer global'
Add BGP channel option 'next hop prefer global' that modifies BGP
recursive next hop resolution to use global next hop IPv6 address instead
of link-local next hop IPv6 address for immediate next hop of received
routes.
