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.

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.

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.

Allow to define static roa/flow routes without dest.
|
|
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.

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.

Add flow4/flow6 network and rt-table type and operations, config grammar
and static protocol support.
Squashed flowspec branch from Pavel Tvrdik.
|
|
|
|
Integrated and extensible BGP with generalized AFI handling,
support for IPv4+IPv6 AFI and unicast+multicast SAFI.
|
|
Example:
bird> eval (1.2.0.0/16 max 20 as 1234).asn
1234
Todo: Should be described in user docs

The patch adds support for channels, structures connecting protocols and
tables and handling most interactions between them. The documentation is
missing yet.

- 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

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.

Use net_addr for interface address prefixes, support net_addr in
configuration parser.
|
|
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.
