Use a hierarchical bitmap in a routing table to assign ids to routes, and
then use bitmaps (indexed by route id) in channels to keep track whether
routes were exported. This avoids unreliable and inefficient re-evaluation
of filters for old routes in order to determine whether they were exported.
|
|
Basic bitmap is obvious. Hierarchical bitmap is structure of several
bitmaps, where higher levels are conjunctions of intervals on level
below, allowing for efficient lookup of first unset bit.

During NLRI parsing of IPv6 Flowspec, dst prefix was not properly
extracted from NLRI, therefore a received flow was stored in a different
position in flowspec routing table, and was not reachable by command
'show route <flow>'.
Add proper prefix part accessors to flowspec code and use them from BGP
NLRI parsing code.
Thanks to Alex D. for the bugreport.

We already had them defined on BGP level, but they are more general.
|
|
Use 'l' for s64/u64 instead of for long/ulong, as that is much more
useful. Also make number() correct with regard to signed/unsigned
typecasts.
|
|
Instead of having large stack buffer for max amount of AFI/SAFI pairs.
The old code is not correct w.r.t. extendeded option length, as more
AFI/SAFI pairs may fit into the capability option.
|
|
Extends BGP options/capabilities data length to 16bit, to avoid issues
with too many capabilities. See draft-ietf-idr-ext-opt-param-07

Add option to send solicited router advertisements as unicast directly
to soliciting nodes instead of as multicast to all-nodes group.

Mismatched types to printf(). The old code coincidentally worked on amd64
due to its calling conventions.
Thanks to Maximilian Eschenbacher for the bugreport.

a little slower.
When the parallel execution comes into place, we'll likely enforce this
C11 feature. It's much simpler and also faster than pthread_[sg]etspecific().
|
|
The glibc's generic parser is slow due to its versatility. Specialized
parsers for base-10 and base-16 are much faster and we don't use other
bases.

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.

Add support for OSPFv2 Opaque LSAs (RFC 5250) and for Router Information
LSA (RFC 7770). The second part is here mainly for testing opaque LSAs.

The new MRT protocol is responsible for periodic RIB table dumps in the
MRT format (RFC 6396). Also the existing code for BGP4MP MRT dumps is
refactored and splitted between BGP to MRT protocols, will be more
integrated into MRT in the future.
Example:
protocol mrt {
table "*";
filename "%N_%F_%T.mrt";
period 60;
}
It is partially based on the old MRT code from Pavel Tvrdik.

Release BIRD now and then let it flee
(use the melody of well-known Oh Freedom!)

Use like this:
void func(const char *msg, va_list args) {
...
bvsnprintf(buf, len, "file %s, line %d: %V (foo %d, bar %d)", file, line, msg, &args, foo, bar);
...
}

BSD systems cannot use SO_DONTROUTE, because it does not work properly
with multicast packets (perhaps it tries to find iface based on multicast
group address). But we can use MSG_DONTROUTE sendmsg() flag for unicast
packets. Works on FreeBSD, is ignored on OpenBSD and is broken on NetBSD
(i guess due to integrated routing table and ARP table).
|
|
Simplify neighbor cache code, fix several minor bugs, and improve
handling of ONLINK flag.

on case-insensitive filesystems

Included are Makefile implicit rules to show the preprocessed source.
When debugging something around this, it may be handy.

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.
Minor changes by Ondrej Santiago Zajicek.
