rta_free(), which may cause crash. The bug was introduced in 1.4.1 from
merging add-path branch."

The BIRD project aims to develop a fully functional dynamic IP
routing daemon primarily targeted on (but not limited to) UNIX-like
systems and distributed under the GNU General Public License.
* Both IPv4 and IPv6
* Multiple routing tables (not on OpenBSD yet)
* BGP
* RIP
* OSPF (IPv4 only)
* Static routes
* Inter-table protocol
* Command-line interface
* Soft reconfiguration
* Powerful language for route filtering
Due to bird's build system, packages are split: the bird package
contains IPv4 daemons, bird-v6 contains IPv6 daemons (build with
FLAVOR=v6), and bird-doc contains the manual.
