Add generic interface for generating and verifying MACs (message
authentication codes). Replace multiple HMAC implementation with
a generic one.
|
|
There are several unresolved -Wmissing-field-initializers on older
versions of GCC than 5.1, all of them false positive.

|
The add() function used to prepend a new community to clist, but after
this fix the add() function appends new community.

|
Some memory was being allocated from bad linpool, not from the given one
as they should.
Thanks to Madhu and Justin Cattle for reporting this.
|
|
Thanks to Micah Anderson for bug report and Ondrej Zajicek for the idea!

Add support for large communities (draft-ietf-idr-large-community),
96bit alternative to RFC 1997 communities.
Thanks to Matt Griswold for the original patch.

Kernel protocol calls rt_export_merged(), which used @rte_update_pool for
temporary allocations, supposing it is called from other functions from
rt-table.c that handles locking and flushing of the linpool. Therefore,
linpool was not flushed properly and memory leaked.
Add linpool argument to rt_export_merged() and use @krt_filter_lp when
called from kernel protocol.
Thanks to Justin Cattle and Alexander Frolkin for the bugreport.

This updates the documentation to correctly mention Babel when protocols
are listed, and adds examples and route attribute documentation to the
Babel section of the docs.

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.

This patch implements the IPv6 subset of the Babel routing protocol.
Based on the patch from Toke Hoiland-Jorgensen, with some heavy
modifications and bugfixes.
Thanks to Toke Hoiland-Jorgensen for the original patch.

When enabled, direct protocol generates routes only if the underlying
link state is up.
|
|
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.

Counter exp_routes is increased during initial route feed after GR
recovery, so it has to start with zero, otherwise BIRD will end with
double value in exp_routes.
|
|
When a kernel route changed, function krt_learn_scan() noticed that and
replaced the route in internal kernel FIB, but after that, function
krt_learn_prune() failed to propagate the new route to the nest, because
it confused the new route with the (removed) old best route and decided
that the best route did not changed.
Wow, the original code (and the bug) is almost 17 years old.

... and reworked the hashes a bit. Also added mem_hash function
which just computes a hash of given memory block.

Fix reading from freed memory.

If rt_notify is NULL, the export must always stay DOWN.
|
|
The patch adds support for channels, structures connecting protocols and
tables and handling most interactions between them. The documentation is
missing yet.
