Also all loops have their basic resource pool for allocations which are
auto-freed when the loop is stopping.

|
|
* internal tables are now more standalone, having their own import and
export hooks
* route refresh/reload uses stale counter instead of stale flag,
allowing to drop walking the table at the beginning
* route modify (by BGP LLGR) is now done by a special refeed hook,
reimporting the modified routes directly without filters
|
|
Channels have now included rt_import_req and rt_export_req to hook into
the table instead of just one list node. This will (in future) allow for:
* channel import and export bound to different tables
* more efficient pipe code (dropping most of the channel code)
* conversion of 'show route' to a special kind of export
* temporary static routes from CLI
The import / export states are also updated to the new algorithms.

Routes are now allocated only when they are just to be inserted to the
table. Updating a route needs a locally allocated route structure.
Ownership of the attributes is also now not transfered from protocols to
tables and vice versa but just borrowed which should be easier to handle
in a multithreaded environment.

It is an auxiliary key in the routing table, not a route attribute.

Remove assumption that main channel is the only channel.

It was mixed-up if hostname is IPv6 address, and reporting separate
values (like port) on separate lines fits better into key-value style
of 'show protocols all' output. Also, the patch simplifies transport
identification formatting (although it is unused now).
Thanks to Alarig Le Lay for the suggestion.

Add 'ignore max length' option to RPKI protocol, which ignores received
max length in ROA records and instead uses max value (32 or 128). This
may be useful for implementing loose RPKI check for blackholes.

Compare the new timing parameters with the old configuration, not with
the temporary state of the current connection.
The timing values in struct rpki_cache is updated by a version 1 End Of
Data PDU, unless this behavior is suppressed by the configuration
explicitly by the "keep" keyword. Consequently, every reconfiguration
of BIRD triggers a reconnection even if it is not necessary.

The old code used just sizeof(struct sockaddr) bytes of IP address.

This supersedes the EAP_* constants.

Multiple definitions of same channels are forbidden, but inherited
channel can be redefined. In such case channel options are merged.

The old timer interface is still kept, but implemented by new timers. The
plan is to switch from the old inteface to the new interface, then clean
it up.

Allow to define static roa/flow routes without dest.

The RPKI protocol (RFC 6810) using the RTRLib
(http://rpki.realmv6.org/) that is integrated inside
the BIRD's code.
Implemeted transports are:
- unprotected transport over TCP
- secure transport over SSHv2
Example configuration of bird.conf:
...
roa4 table r4;
roa6 table r6;
protocol rpki {
debug all;
# Import both IPv4 and IPv6 ROAs
roa4 { table r4; };
roa6 { table r6; };
# Set cache server (validator) address,
# overwrite default port 323
remote "rpki-validator.realmv6.org" port 8282;
# Overwrite default time intervals
retry 10; # Default 600 seconds
refresh 60; # Default 3600 seconds
expire 600; # Default 7200 seconds
}
protocol rpki {
debug all;
# Import only IPv4 routes
roa4 { table r4; };
# Set cache server address to localhost,
# use default ports tcp => 323 or ssh => 22
remote 127.0.0.1;
# Use SSH transport instead of unprotected transport over TCP
ssh encryption {
bird private key "/home/birdgeek/.ssh/id_rsa";
remote public key "/home/birdgeek/.ssh/known_hosts";
user "birdgeek";
};
}
