The MPLS subsystem manages MPLS labels and handles their allocation to
MPLS-aware routing protocols. These labels are then attached to IP or VPN
routes representing label switched paths -- LSPs.
There was already a preliminary MPLS support consisting of MPLS label
net_addr, MPLS routing tables with static MPLS routes, remote labels in
next hops, and kernel protocol support.
This patch adds the MPLS domain as a basic structure representing local
label space with dynamic label allocator and configurable label ranges.
To represent LSPs, allocated local labels can be attached as route
attributes to IP or VPN routes with local labels as attributes.
There are several steps for handling LSP routes in routing protocols --
deciding to which forwarding equivalence class (FEC) the LSP route
belongs, allocating labels for new FECs, announcing MPLS routes for new
FECs, attaching labels to LSP routes. The FEC map structure implements
basic code for managing FECs in routing protocols, therefore existing
protocols can be made MPLS-aware by adding FEC map and delegating
most work related to local label management to it.

Basic fib_get() / fib_find() test for random prefixes, FIB_WALK() test,
and benchmark for fib_find(). Also generalize and reuse some code from
trie tests.
|
|
There are many compatibility issues with echo -e, scratch that.
|
|
There ware missing dependencies for proto-build.c generation, which
sometimes lead to failed builds, and ignores changes in the set of
built protocols. Fix that, and also improve formatting of proto-build.c

- Unit Testing Framework (BirdTest)
- Integration of BirdTest into the BIRD build system
- Tests for several BIRD modules
Based on squashed Pavel Tvrdik's int-test branch, updated for
current int-new branch.
|

Also removed the lib-dir merging with sysdep. Updated #include's
accordingly.
Fixed make doc on recent Debian together with moving generated doc into
objdir.
Moved Makefile.in into root dir
Retired all.o and birdlib.a
Linking the final binaries directly from all the .o files.

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.

- ROA tables, which are used as a basic part for RPKI.
- Commands for examining and modifying ROA tables.
- Filter operators based on ROA tables consistent with RFC 6483.

on AS paths and community sets.
Moved as_path_prepend() there.
Pavel, please move the other functions as well.

Added `show symbols' command which dumps whole symbol table together
with symbol types etc.

with protocols wanting to use the same port on the same interface
during reconfiguration time.
How to use locks: In the if_notify hook, just order locks for the
interfaces you want to work with and do the real socket opening after the
lock hook function gets called. When you stop using the socket, close
it and rfree() the lock.
Please update your protocols to use the new locking mechanism.

do nothing more advanced for them

it sits here instead of `proto/dev'.
|

terrible kernel interface (SIOGIFCONF and friends).
|
|
|
|
complete now.
