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.

Tests may take longer than 5 s to complete on slow/virtual machines.

The prefix trie now supports longest-prefix-match query by function
trie_match_longest_ipX() and it can be extended to iteration over all
covering prefixes for a given prefix (from longest to shortest) using
TRIE_WALK_TO_ROOT_IPx() macro.
|
|
Add trie tests intended as benchmarks that use external datasets
instead of generated prefixes. As datasets are not included, they
are commented out by default.
|
|
Add tests explicitly matching insides and outsides of trie and update
tests to do testing of both IPv4 and IPv6 tries.

Initial parsing of test.conf must be done directly in filter_test main,
while reconfiguration is handled as a regular test. Also fix several
minor issues in test code.

The C11 specification allows only sig_atomic_t and _Atomic variable
access. All other accesses to global variables are undefined behavior.
Using int was probably OK on x86 and x86_64; yet there were some reports
from other architectures (especially some MIPS) that in rare cases,
after issuing SIGHUP, BIRD did strange things.

This supersedes the EAP_* constants.

This patch ensures width of output lines from testing framework (not
debug output). So output piped lined into file that has default width 80
cols is now correctly wrapped.

- 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.
