This is merely a const propagation. There was no problem in there.

2928c5bcc7 Fletcher16 test fixed to work at bigendian architectures.
To be honest, it was wrong in concept, anyway it accidentally worked.

78e4a123bb BGP: Handle flowspec rules without dst part
The RFC 5575 does not explicitly reject flowspec rules without dst part,
it just requires dst part in validation procedure for feasibility, which
we do not implement anyway. Thus flow without dst prefix is syntactically
valid, but unfeasible (if feasibilty testing is done).

Thanks to Alex D. for the bugreport.

757cab18d6 BGP: Support for MD5SIG together with remote range
When dynamic BGP with remote range is configured, MD5SIG needs to use
newer socket option (TCP_MD5SIG_EXT) to specify remote addres range for
listening socket.

Thanks to Adam Kułagowski for the suggestion.

5ea39eaa96 Nest: Use bitmaps to keep track of exported routes
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.

af02b83b88 Lib: Basic and hierarchical bitmaps
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.

0f88200247 BGP: Fix processing of IPv6 Flowspec
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.

useful. Also make number() correct with regard to signed/unsigned
typecasts.

4fa0e472cf BGP: Use reallocation for capability structure
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.

6479e403ef Filters: If somebody doesn't like _Thread_local, don't fail for now, just be 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().

2915e711f7 Custom number parser to speed up config parsing
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.

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.

863ecfc785 The MRT protocol
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.

318acb0f6c BSD: Use MSG_DONTROUTE for unicast packets on FreeBSD
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).
