• Added dependency to libcdada in an effort to streamline basic data structures needed for everyday coding. All new structures will make use of libcdada, old ones will be ported over time. Libcdada offers basic data structures in C: ie. list, set, map/ hash table, queue and is a libstdc++ wrapper. Many thanks to Marc Sune ( @msune ) for his work with libcdada and his enormous help facilitating the integration.
• BGP daemon: added suppport for Accumulated IGP Metric Attribute (AIGP) and Label-Index TLV of Prefix-SID Attribute.
• BGP daemon: added SO_KEEPALIVE TCP socket option (ie. to keep the sessions alive via a firewall / NAT kind of device). Thanks to Jared Mauch ( @jaredmauch ) for his patch.
• BGP daemon: if comparing source TCP ports among BGP peers is being enabled (config directive tmp_bgp_lookup_compare_ports), print also BGP Router-ID as distinguisher as part of log/dump output.
• BMP daemon: added support for HAProxy Proxy Protocol Header in the first BMP message in order to determine the original sender IP address and port. The new bmp_daemon_parse_proxy_header config directive enables the feature. Contribution is by Peter Pothier ( @pothier-peter ).
• BMP daemon: improved support and brought implementation on par with the latest drafting efforts at IETF wrt draft-cppy-grow-bmp- path-marking-tlv, draft-xu-grow-bmp-route-policy-attr-trace, draft-ietf-grow-bmp-tlv and draft-lucente-grow-bmp-tlv-ebit.
• BMP daemon: added 'bgp_agent_map' equivalent feature for BMP.
• nfacctd, nfprobe plugin: added support for collection and export of NetFlow/IPFIX data over Datagram Transport Layer Security (in short DTLS). The feature depends on the GnuTLS library.
• nfacctd: added support for deprecated NetFlow v9 IE [#104] (layer2packetSectionData) as it is implemented for NetFlow-lite on Cisco devices. Reused code from IPFIX IE [#315].
• nfacctd: added support for MPLS VPN RD IE [#90]. This comes in two flavours both found across vendor implementations: 1) IE present in flow data and 2) IE present in Options data as a lookup from IE [#234] (ingressVRFID) and [#235] (egressVRFID).
• nfacctd: added a new timestamp_export aggregation primitive to record the timestamp being carried in the header of NetFlow/IPFIX messates (that is, the time at which the export was performed).
• nfprobe plugin: added support for ICMP/ICMPv6 information as part of the NetFlow/IPFIX export. The piece of info is encoded in the destination port field as per the current common understandings across vendors. As a result of that, the 'dst_port' primitive is to be part of the aggregation method in order to leverage this feature.
• MySQL plugin: introduced support to connect to a MySQL server via UNIX sockets.
• tee plugin: added crc32 hash algorithm as a new balancing option for nodes in the receiving pool. It hashes original exporter IP address against a crc32 function. Thanks to @edge-intelligence for the contribution.
• Massive improvements carried out on the Continuous Integration (CI) side, ie. to ensure better quality of the code, and on the containerization side by offering official stable / bleeding edge Docker images. Huge thanks to Marc Sune ( @msune ) to make all of this possible.
