Ondrej Zajicek (work) 47d92d8f9d Nest: Clean up main channel handling

Ondrej Zajicek (work) ea3c6c1a15 Static: Fix handling of 'net' attribute in per-route filters
We need to define 'net' field temporarily as it may be accessed by
per-route filters.

Thanks to Damian Zaremba for the bugreport.

Ondrej Zajicek (work) 1678bc0746 Fix some failed asserts due to add_tail()
When config structures are copied due to template application,
we need to reset list node structure before calling add_tail().

Thanks to Mikael Magnusson for patches.

Ondrej Zajicek (work) 3347aaafec Static: Support for multiple routes with the same network
Add support for proper handling of multiple routes with the same network
to the static protocol. Routes are distinguished by internal index, which
is assigned automatically (sequentially for routes within each network).
Having different route preference or igp_metric attribute is optional.

Ondrej Zajicek (work) 9d3fc3062b BFD: Allow per-request session options
BFD session options are configured per interface in BFD protocol. This
patch allows to specify them also per-request in protocols requesting
sessions (currently limited to BGP).

Ondrej Zajicek (work) c26c6bc2d7 Show info from multiple protocols when protocol is not specified
Most commands like 'show ospf neighbors' fail when protocol is not
specified and there are multiple instances of given protocol type.
This is annoying in BIRD 2, as many protocols have IPv4 and IPv6
instances. The patch changes that by showing output from all protocol
instances of appropriate type.

Note that the patch also removes terminating cli_msg() call from these
commands and moves it to the common iterating code.

Thanks to Alexander Zubkov for notice and patches.

Maria Matejka 4c553c5a5b Filter refactoring: dropped the recursion from the interpreter
This is a major change of how the filters are interpreted. If everything
works how it should, it should not affect you unless you are hacking the
filters themselves.

Anyway, this change should make a huge improvement in the filter performance
as previous benchmarks showed that our major problem lies in the
recursion itself.

There are also some changes in nest and protocols, related mostly to
spreading const declarations throughout the whole BIRD and also to
refactored dynamic attribute definitions. The need of these came up
during the whole work and it is too difficult to split out these
not-so-related changes.

Ondrej Zajicek (work) a1f5e514ef Implement onlink flag for nexthops
Add proper support for per-nexthop onlink flag in routes to handle next
hop addresses that are not covered by interface IP ranges. Supported by
kernel and static protocols.

Thanks to Vincent Bernat for the idea.

Ondrej Zajicek (work) ffb38dfb8b Static: Support for dual-AF IGP tables
When recursive routes with hybrid next hops (e.g. IPv6 route with IPv4 next
hop) are allowed, we need both IPv4 and IPv6 IGP tables.

Ondrej Zajicek (work) 7126cadf80 Static: Minor overhaul
The patch fixes several bugs introduced in previous changes, simplifies
the protocol by handing routes uniformly, introduces asynchronous route
processing to avoid issues with separate notifications for each next-hop
in ECMP routes, and makes reconfiguration faster by avoiding quadratic
complexity.

Jan Moskyto Matejka 5b208e296f Removing (struct rta)->cast. Never used. 2016-12-22 13:09:59 +01:00
Jan Moskyto Matejka 4e276a8920 Merged multipath and single-path data structures.
Dropped struct mpnh and mpnh_*()
Now struct nexthop exists, nexthop_*(), and also included struct nexthop
into struct rta.

Also converted RTD_DEVICE and RTD_ROUTER to RTD_UNICAST. If it is needed
to distinguish between these two cases, RTD_DEVICE is equivalent to
IPA_ZERO(a->nh.gw), RTD_ROUTER is then IPA_NONZERO(a->nh.gw).

From now on, we also explicitely want C99 compatible compiler. We assume
that this 20-year norm should be known almost everywhere.

Jan Moskyto Matejka 2003a18407 Route update: move table lookup from protocols into rte_update2().
Many protocols do almost the same when creating a rte_update request
before calling rte_update2(). This commit should simplify the protocol
side of the route-creation routine.

configuration parser.

Ondrej Zajicek (work) fe9f1a6ded Initial commit on integrated BIRD
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.

Ondrej Zajicek 1321e12ac4 Static: Allows to specify attributes for static routes
The patch adds suport for specifying route attributes together with
static routes, e.g.:

 route 10.1.1.0/24 via 10.0.0.1 { krt_advmss = 1200; ospf_metric1 = 100; };

Ondrej Zajicek d40c26594c Fixes issues with static protocol reconfiguration.
The old static route was not removed when the nexthop changed and the
new one was not viable (no neighbor).

Thanks to Pierluigi Rolando for the original patch.

Ondrej Zajicek 094d2bdb79 Implements ADD-PATH extension for BGP.
Allows to send and receive multiple routes for one network by one BGP
session. Also contains necessary core changes to support this (routing
tables accepting several routes for one network from one protocol).
It needs some more cleanup before merging to the master branch.

.
