------------------------------------------------------------------- Sun Nov 10 19:54:15 UTC 2024 - Martin Hauke <mardnh@gmx.de> - Update to version 1.7.9 * https://github.com/pmacct/pmacct/releases/tag/v1.7.9 ------------------------------------------------------------------- Sat Jan 7 14:38:01 UTC 2023 - Dirk Müller <dmueller@suse.com> - update to 1.7.8: + Introduced support for eBPF for all daemons: if SO_REUSEPORT is supported by the OS and eBPF support is compiled in, this allows to load a custom load-balancer. To load-share, daemons have to be part of the same cluster_name and each be configured with a distinct cluster_id. + Introduced support for listening on VRF interfaces on Linux for all daemons. The feature can be enabled via nfacctd_interface, bgp_daemon_interface and equivalent knobs. Many thanks to Marcel Menzel ( @WRMSRwasTaken ) for this contribution. + pre_tag_map: introduced limited tagging / labelling support for BGP (pmbgpd), BMP (pmbmpd), Streaming Telemetry (pmtelemetryd) daemons. ip, set_tag, set_label keys being currently supported. + pre_tag_map: defined a new pre_tag_label_encode_as_map config knob to encode the output 'label' value as a map for JSON and Apache Avro encodings, ie. in JSON "label": { "key1": "value1", "key2": "value2" }. For keys and values to be correctly mapped, the '%' delimiter is used when composing a pre_tag_map, ie. "set_label=key1%value1,key2%value2 ip=0.0.0.0/0". Thanks to Salvatore Cuzzilla ( @scuzzilla ) for this contribution. + pre_tag_map: introduced support for IP prefixes for src_net and dst_net keys for indexed maps (maps_index set to true). Indexing being an hash map, this feature currently tests data against all defined IP prefix lenghts in the map for a match (first defined matching prefix wins). + pre_tag_map: introduced two new 'is_nsel', 'is_nel' keys to check for the presence of firewallEvent field (233) and natEvent field (230) in NetFlow/IPFIX respectively in order to infer whether data is NSEL / NEL. If set to 'true' this does match NSEL / NEL data, if set to 'false' it does match non NSEL / NEL data respectively. + Introduced a new mpls_label_stack primitive, encoded as a string and includes a comma-separated list of integers (label values). Thanks to Salvatore Cuzzilla ( @scuzzilla ) for this contribution. + Introduced a new fw_event primitive, to support NetFlow v9/ IPFIX firewallEvent 233 Information Element. + Introduced a new tunnel_tcp_flags primitive for pmacctd and sfacctd to record TCP flags for the inner layer of a tunneled technology (ie. VXLAN). Also tunnel_dst_port decoding was fixed for sfacctd. + Introduced support for in/out VLAN support for sfacctd. To be savy, 'in_vlan' and 'vlan' were muxed onto the same primitive depending on the daemon being used. Thanks to Jim Westfall ( @jwestfall69 ) for this contribution. + Introduced a new mpls_label_stack_encode_as_array config knob to encode the MPLS label stack as an array for JSON and Apache Avro encodings, ie. in JSON "mpls_label_stack": [ "0-label0", "1-label1", "2-label2", "3-label3", "4-label4", "5-label5" ] and in Avro "name": "mpls_label_stack", "type": { "type": "array", "items": { "type": "string" } }. Thanks to Salvatore Cuzzilla ( @scuzzilla ) for this contribution. + Introduced a new tcpflags_encode_as_array config knob to encode TCP flags as an array for JSON and Apache Avro, ie. in JSON "tcp_flags": [ "URG", "ACK", "PSH", "RST", "SYN", "FIN" ] and in Avro "name": "tcp_flags", "type": { "type": "array", "items": { "type": "string" } }. Thanks to Salvatore Cuzzilla ( @scuzzilla ) for this contribution. + Introduced a new fwd_status_encode_as_string config knob to encode the 'fwd_status' primitive in human-readable format like described by RFC-7270 Section 4.12 when JSON or Avro formats are selected for output. Thanks to Salvatore Cuzzilla ( @scuzzilla ) for this contribution. + Introduced a new protos_file to define a list of (known/ interesting/meaningful) IP protocols. Both protocol names, ie. "tcp", and protocol numbers, ie. 1 (for icmp), are accepted. IANA reserved protocol value 255 is used to bucket as 'others' those IP protocols not matching the ones defined in the list. + Introduced a new tos_file to define a list of (meaningful) IP ToS values; if tos_encode_as_dscp is set to true then DSCP values are expected as part of the file. The directive uses value 255 to bucket as 'others' those ToS/DSCP values not matching the ones defined in the list. + A new tos_encode_as_dscp config knob makes pmacct to honour only the 6 bits used by DSCP and report only on those. + BGP, BMP, Streaming Telemetry daemons: introduced a new dump_time_slots config knob to spread the load deriving by dumps over the configured refresh time interval. The interval is divided into time slots and nodes are assigned to such slots. The slot for each node is determined using its IP address. Thanks to Raphael Barazzutti ( @rbarazzutti ) for this contribution. + BGP, BMP daemons: End-of-RIB messages are now being exposed in the output feed in order to facilitate tracking their arrival (or not!). + pmtelemetryd: aligned daemon to the latest Unyte UDP-Notif API (0.6.1) and related standardization draft-ietf-netconf-udp-notif + RPKI daemon: added case for input "asn" value being integer (ie. "asn" : 2914) on top of the string case (ie. "asn" : "AS2914"). + Kafka, amqp plugins: introduced a new writer_id_string config knob to allow to customize the the "writer_id" field value. A few variables are supported along with static text definitions. + Added a new aggregate_unknown_etype config knob to account also frames with EtherTypes for which there is no decoding support and allow to aggregate them by the available Ethernet L2 fields (ie. 'src_mac', 'dst_mac', 'vlan', 'cos', 'etype'). Thanks to @singularsyntax for this contribution. + Added a new bgp_daemon_add_path_ignore config knob to ignore (do not advertise back) the ADD-PATH capability advertised by remote BGP peers. + nfacctd, sfacctd: extended the possibility to run daemons from a user with non root privileges to these daemons. + nfacctd: if Information Element 90 (MPLS VPN RD) is present in NetFlow v9/IPFIX, make it available for BGP/BMP correlation. + pmacctd, sfacctd: introduced basic support for QinQ, 802.1AD. + [print|kafka|amqp]_preprocess: added suppport for 'maxp', 'maxb' and 'maxf' keys when preprocessing aggregates of non- SQL plugins. Thanks to Andrew R. Lake ( @arlake228 ) for this contribution. + nDPI: newer versions of the library (ie. >= 4.0) bring changes to the API. pmacct is now aligned to compile against these. At the same time support for nDPI 3.x was dropped. ! fix, plugin_common.[ch]: when stitching feature was enabled, ie. nfacctd_stitching, timestamp_min was never reset. Also both timestamp_min and timestamp_max were clamped to sec granularity. ! fix, BGP, BMP daemons: added a tmp_bgp_daemon_origin_type_int to print out BGP "origin" field as int (legacy behaviour) instead of string (current behaviour). In a future major release the legacy behaviour will be dropped. ! fix, BGP, BMP daemons: MPLS labels are now encoded in both JSON and Apache Avro as 'mpls_label' instead of 'label'. This is to align behaviour with pre_tag_map where 'label' has a different semantic. ! fix, BGP, BMP daemons: resolved memory leak when encoding log messaging (logmsg) in Avro format with Schema Registry support. ! fix, BGP daemon: improved handling of ADD-PATH capability, making it per-AF (as it is supposed to be) and not global. ! fix, BMP daemon: now checking that ADD-PATH capability is enabled at both ends of the monitored session (check both BGP OPEN in a Peer Up message) in order to infer that the capability exchange was successful. Also some heuristics were added to conciliate BGP Open vs BGP Update 4-bytes ASN reality. ! fix, nfacctd: improved parsing of NetFlow v9 Options data particularly when multiple IEs are packed as part of a flowset. ! fix, nfacctd: corrected parsing of Information Element 351 (layer2SegmentId). ! fix, pmacctd: improved processing of pcap_interfaces_map for cases where the same interface is present multiple times (maybe with different directions). Also, if the map is empty then bail out at startup. ! fix, pmacctd: SEGV when ICMP/ICMPv6 traffic was processed and 'flows' primitive was enabled. ! fix, pmacctd: sampling_rate primitive value was not reported correctly when 'sampling_rate' config directive was specified. ! fix, pmbgpd, pmpmbd, pmtelemtryd: changed SIGCHLD handler to prevent zombification of last spawned data dump writer. ! fix, Kafka plugin: moved the schema registration from the dump writer to the plugin process in order to register the schemas only once at plugin startup and not on every start of a writer process. Thanks to Uwe Storbeck ( @ustorbeck ) for this contribution. ! fix, Kafka plugin: a check for kafka_partition was missing, leading the plugin to always use the default partitioner instead of sending data to the configured fixed partition. Thanks to Martin Pels ( @rodecker ) for this contribution. ! fix, nfprobe plugin: BGP data enrichment was not working due to a mistakenly moved pointer. ! fix, sfprobe plugin: AS-PATH was being populated even when null; added a check to see if the destination AS is not zero in order to put the destination AS into the AS-PATH for sFlow packets. Thanks to Marcel Menzel ( @WRMSRwasTaken ) for this contribution. ! fix, networks_file: remove_dupes() was making partial commits of valid rows hence creating data inconsistencies. ! fix, pre_tag_map: resolved a potential string overflow that was being triggered in pretag_append_label() when data would be assigned more than one single label. Also now allow ',' chars in set_label. ! fix, maps_index: uninitialized var could cause SEGV in case no results are found in the map index. Also introduced support for catch-all rules, ie. "set_label=unknown". ! fix, maps_index: optimized the case of no 'ip' key specified (for nfacctd and sfacctd): when indexing is enabled, prevent recirculation from happening, ie. test v4 first then v6, since the 'ip' key is not going to be part of the hash serializer. ! fix, pretag.c: allow to allocate maps greater than 2GB in size. Also several optimizations were carried out yelding to a better memory utilization for allocated maps along with improved times to resolve JEQs. ! fix, pre_tag_label_filter: optimized and improved runtime evaluation part of this feature, avoiding a costly strdup() and returning immediately on certain basic mismatch conditions. ! fix, kafka_common.[ch]: a new p_kafka_produce_data_and_free() is invoked to optimize memory allocations and releases. ! fix, plugin_cmn_avro.c: when a schema registry is being defined, ie. kafka_avro_schema_registry, the logic to generate the schema name has been changed: use topic plus record name as the schema name, use underscore as separator within the record name, stop adding a "-value" suffix. Thanks to Uwe Storbeck ( @ustorbeck ) for this contribution. ! fix, util.c: roundoff_time() to reason always with the locally configured time, like for the rest of functional (as in non-data) timestamps, ie. refresh time, deadline, etc. ! fix, log.c: when log messages are longer than message buffer, the message gets cut off. As the trailing newline also gets cut off the message will be concatenated with the following message which makes the log hard to read. Thanks to Uwe Storbeck ( @ustorbeck ) for this contribution. - Completed the retirement of legacy packet classification based on home-grown code (Shared Objects) and the L7 layer project. - Removed the mpls_stck_depth primitive due to the introduction of the mpls_label_stack primitive. ------------------------------------------------------------------- Sun Nov 7 19:47:40 UTC 2021 - Martin Hauke <mardnh@gmx.de> - Update to version 1.7.7 + BGP, BMP, Streaming Telemetry daemons: introduced parallelization of dump events via a configurable amount of workers where the unit of parallelization is the exporter (BGP, BMP, telemetry exporter), ie. in a scenario where there are 4 workers and 4 exporters each worker is assigned one exporter data to dump. + pmtelemetryd: added support for draft-ietf-netconf-udp-notif: a UDP-based notification mechanism to collect data from networking devices. A shim header is proposed to facilitate the data streaming directly from the publishing process on network processor of line cards to receivers. The objective is a lightweight approach to enable higher frequency and less performance impact on publisher and receiver process compared to already established notification mechanisms. + BGP, BMP, Streaming Telemetry daemons: now correctly honouring the supplied Kafka partition key for BGP, BMP and Telemetry msg logs and dump events. + BGP, BMP daemons: a new "rd_origin" field is added to output log/ dump to specify the source of Route Distinguisher information (ie. flow vs BGP vs BMP). + pre_tag_map: added ability to tag new NetFlow/IPFIX and sFlow sample_type types: "flow-ipv4", "flow-ipv6", "flow-mpls-ipv4" and "flow-mpls-ipv6". Also added a new "is_bi_flow" true/false key to tag (or exclude) NSEL bidirectional flows. Added as well a new "is_multicast" true/false config key to tag (or exclude) IPv4/IPv6 multicast destinations. + maps_index: enables indexing of maps to increase lookup speeds on large maps and/or sustained lookup rates. The feature has been remplemented using stream-lined structures from libcdada. This is a major work that helps preventing the unpredictable behaviours caused by the homegrown map indexing mechanism. + maps_index: support for indexing src_net and dst_net keywords has been added. + Added <daemon_name>_ipv6_only config directives to optionally enable the IPV6_V6ONLY socket option. Also changed the wrong setsockopt() IPV6_BINDV6ONLY id to IPV6_V6ONLY. + Added log function to libserdes to debug transactions with the Schema Registry when kafka_avro_schema_registry is set. + nDPI: newer versions of the library (ie. >= 3.5) bring changes to the API. pmacct is now aligned to compile against these. + pmacctd: added pcap_arista_trailer_offset config directive since Arista has changed the structure of the trailer format in recent releases of EOS. + More improvements also carried out in the space of the Docker images being created: optimized image size and a better layered pipeline. + libcdada shipped with pmacct was upgraded to version 0.3.5. ! build system: several improvements carried out in this area, ie. improved MySQL checks, introduced pcap-config tool for libpcap, compiling on BSD/old compilers, etc. ! fix, nfacctd: improved euristics to support the case of flows with both IPv4 and IPv6 source / destination addresses (either or populated). Also improved euristics to distinguish event data vs traffic data in NetFlow v9/IPFIX from Cisco 9300/9500, ASA firewalls and Cisco 4500X. ! fix, nfacctd: improved support for initiatorOctets (IE #231) and responderOctets (IE #232). ! fix, nfacctd: in NF_mpls_vpn_id_handler() double ntohl() calls were applied for the case of 'vrfid'-encoded mpls_vpn_rd field. ! fix, sfacctd: wrong ethertype set for VLAN-tagged, MPLS-labelled IPv6 traffic. Impacting BGP resolution among others. ! fix, BGP, BMP daemons: parsing improvements: added a check for BGP Open message and BGP Open Options lengths. Strengthened parsing of Peer Up, Route Monitoring and Peer Down v4 messages. ! fix, BGP, BMP daemon: when using Avro encoding and Avro Schema Registry, attempt to reconnect if serdes schemas are voided. Also now checking for serdes schema definitions before doing a serdes_schema_serialize_avro() to avoid triggering a SEGV. Finally improved serdes logging. ! fix, BGP, Streaming Telemetry daemons: in daemon logs, summary counters for amount of tables / entries dumped were wrong. ! fix, BGP daemon: distinguish among null and zero value AIGP and Prefix SID attributes. Same applies for Local Preference and MED attributes. ! fix, BMP daemon: resolved a memory leak in bgp_peers_free(). ! fix, BMP daemon: correctly setting peer_ip and peer_tcp_port JSON fields for Term messages. Also the correct bmp_router value when bmp_daemon_parse_proxy_header feature is enabled. ! fix, BMP daemon: several encoding issues when using Apache Avro ie. u_int64_t now correctly encoded with avro_value_set_long(), certain u_int32_t fields switched to avro_value_set_long() due to lack of unsignedness in Avro encoding, improved various aspectes of Avro-JSON format output, etc. ! fix, pmtelemetryd: wrong parsing of pm_tfind() output was leading to mistaken data attribution of UDP-based peers (always first peer to connect was being picked). ! fix, pmtelemetryd: when set, the pidfile config directive was not being correctly honoured. ! fix, RPKI: the RTR PDU element for maxLength is uint8, therefore it might have been possible to transmit incorrect RTR data. ! fix, SQL plugins: amended the text composition of SQL queries that are involving latitude and longitude keys. ! fix, MySQL plugin: check for 'unix:' prefix string only when a sql_host configuration directive is specified. ! fix, nfprobe: modernized Application Information export. Until the previous release pmacct was adhering to aging NBAR model whereas now NBAR2 has been implemented. ! fix, tee plugin: restored usefulness of tee_source_ip which was broken in 1.7.6. ! fix, maps_index: indexing of mpls_pw_id was broken. Also now, when the feature is enabled, actual data is being referenced in the index structure instead of creating a copy of it; ! fix, kafka_common.c: solved memory leak in p_kafka_set_topic() when Kafka session was getting in down state. ! fix, net_aggr.[ch]: when a networks_file is specified in the config, gracefully handle max memory structure depth; added also de-duplication of entries. ! fix, pmacct-defines.h: if PCAP_NETMASK_UNKNOWN is not defined, ie. in libpcap < 1.1.0, let's define it. ! fix, SO_REUSEPORT feature was being restricted to Linux only in previous releases: now it has been unlocked to all other OS that do support the feature. ! fix, split SO_REUSEPORT and SO_REUSEADDR setsockopt() calls. ! fix, several code warnings catched gcc9 and clang. - Obsoleted sql_history_since_epoch, pre_tag_map_entries and refresh_maps configuration directives. ------------------------------------------------------------------- Tue Oct 19 09:52:31 UTC 2021 - Johannes Segitz <jsegitz@suse.com> - Added hardening to systemd service(s) (bsc#1181400). Modified: * pmacct.nfacctd.service * pmacct.pmacctd.service * pmacct.sfacctd.service ------------------------------------------------------------------- Sun Mar 14 15:56:31 UTC 2021 - Martin Hauke <mardnh@gmx.de> - Update to versino 1.7.6 + 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). + 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. + 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. ! fix, BGP daemon: re-worked internal structuring of 'modern' BGP attributes: for the sake of large-scale space optimization certain attributes are confined in a separate (less used) bgp_info_extra structure. ! fix, BGP daemon: improved support for BGP ADD-PATH, ie. made it per Address-Family rather than global. Also comparisons upon doing route looup were improved and normalized. ! fix, BGP daemon: use split buffers for recv and send functions of the BGP x-connects feature. Also improved validation when processing a bgp_daemon_xconnect_map. ! fix, BGP daemon: when using BGP x-connects, close unused file descriptors in bgp_peer_xconnect_init() in order to avoid quickly reaching the maximum amount of allowed open descriptors in case of BGP flaps. ! fix, BGP daemon: trigger a log message for a missing entry while processing bgp_daemon_xconnect_map in bgp_peer_xconnect_init(). ! fix, BGP daemon: enabled log notifications (that is, log anti- spam measure) upon reaching limit of allowed BGP peers. ! fix, BGP daemon: ecommunity_ecom2str(), first thing make sure that the destination size is enough! Missing this did cause some SEGVs due to heap corruption. ! fix, BGP daemon: solved a memory leak in aspath_make_str_count() by returning result from aspath_make_empty(), if any. Thanks very much to Peter Pothier ( @pothier-peter ) for his contribution. ! fix, BMP daemon: several encoding issues when using Apache Avro ie. missing conditional branching, wrong field names, etc. ! fix, BMP daemon: throw an error for any issues (error or zero length) related to the BGP Update PDU parsing; also added marker and length checks for BGP Open PDU in Peer Up messages. ! fix, BMP daemon: both timestamp of the BMP event and its arrival at the collector are now recorded and printed out separately; before they were wrongly muxed on one single field making it uncertain for the user what was the time reference. ! fix, BMP daemon: correctly print Peer Distinguisher for Route Monitoring messages. Also improved BMP lookup comparisons in order to factor in Peer Distinguisher if any. ! fix, BMP daemon: print 'is_in' boolean for Adj-Rib-In data instead of having it implicit. Also print 'is_post' for Post- Policy Adj-Rib-In data. ! fix, BMP daemon: upon receipt of a Termination message, do proactively close the TCP session. ! fix, nDPI: newer versions of the library (ie. >= 3.2) require calling ndpi_finalize_initialization() somewhere after the detection module init finished. ! fix, pmacctd: link checks were being mistakenly skipped when reading from a pcap_savefile. Also now if a selected aggregation primitive is unsuitable for a given Layer2, it is simply cleared (with an info message issued) instead of making the daemon bail out. | fix, print plugin: bail the plugin out if its output was set to stdout while the daemon was started as daemonized. ! fix, PostgreSQL plugin: in PG_compose_conn_string() allow any intersection of host, port and cafile options. ! fix, nfprobe plugin: changed default export version from NetFlow v5 to IPFIX. ! fix, sfprobe plugin: FreeBSD was complaining of errno 22 (Invalid argument) upon sendto(). ! fix, tee plugin: replication of IPv6 packets has been now tested working. Previously the output message size was obviously encoded wrongly and the checksum (mandatory piece of info to fill in IPv6, contrary to IPv4 where it is optional) was not being computed. ! fix, kafka_common.c: improved p_kafka_check_outq_len() error log message to report the amount of elements have been successfully processed in order to better assess impact and dynamics of the problem when inspecting logs. ! fix, net_aggr.c: if networks_file_filter is set to true, don't add a default route to the table. ! fix, cfg.c: throw error if config file is not a regular file. ! fix, compiling against gcc10: renamed some variables and unified declaration of others in order to be more friendly to the new version of gcc. Also fixed several code warnings catched gcc8. - Removed the IP prefix label feature that was enabled via the --enable-plabel configure script switch. ------------------------------------------------------------------- Sun Jun 28 15:16:43 UTC 2020 - Martin Hauke <mardnh@gmx.de> - Update to versino 1.7.5 * See /usr/share/doc/packages/pmacct/ChangeLog for all changes - Drop patch (addressed by upstream in 686495dd): * pmacct-fix-overflow.patch ------------------------------------------------------------------- Sun Jun 7 20:37:36 UTC 2020 - Martin Hauke <mardnh@gmx.de> - Set CFLAGS+=-fcommon ------------------------------------------------------------------- Mon Mar 30 07:47:03 UTC 2020 - Marcus Meissner <meissner@suse.com> - pmacct-fix-overflow.patch: fixed bufferoverflow in sfacctd. - reenable _FORTIFY_SOURCE that showed that failure ------------------------------------------------------------------- Sun Feb 9 10:02:46 UTC 2020 - Martin Hauke <mardnh@gmx.de> - Update to version 1.7.4p1 fix, pre_tag_map: a memory leak in pretag_entry_process() has been introduced in 1.7.4. ------------------------------------------------------------------- Thu Jan 2 11:41:34 UTC 2020 - Martin Hauke <mardnh@gmx.de> - Update to version 1.7.4 + Introduced support for the 'vxlan' VXLAN/VNI primitive in all traffic daemons + BMP daemon: added support for Peer Up message namespace for TLVs + sfprobe plugin: added support for IPv6 transport for sFlow export. See /usr/share/doc/packages/pmacct/ChangeLog for all changes ------------------------------------------------------------------- Thu Nov 7 20:08:48 UTC 2019 - Martin Hauke <mardnh@gmx.de> - Do not longer build with support for the obsolete GeoIP The GeoIP-interface has been discontinued by Maxmind. See https://support.maxmind.com/geolite-legacy-discontinuation-notice/ for details. Without the database GeoIP is useless. pmacct is now build with support for libmaxminddb (GeoIPv2) that provides the same features but with a new supported interface. ------------------------------------------------------------------- Thu May 16 18:02:07 UTC 2019 - Martin Hauke <mardnh@gmx.de> - Update to version 1.7.3 + Introduced the RPKI daemon to build a ROA database and check prefixes validation status and coverages. Resource Public Key Infrastructure (RPKI) is a specialized public key infrastructure (PKI) framework designed to secure the Internet routing. RPKI uses certificates to allow Local Internet Registries (LIRs) to list the Internet number resources they hold. These attestations are called Route Origination Authorizations (ROAs). ROA information can be acquired in one of the two following ways: 1) importing it using the rpki_roas_file config directive from a file in the RIPE Validator format or 2) connecting to a RPKI RTR Cache for live ROA updates; the cache IP address/port being defined by the rpki_rtr_cache config directive (and a few more optional rpki_rtr_* directives are available and can be reviwed in the CONFIG-KEYS doc). The ROA fields will be populated with one of these five values: 'u' Unknown, 'v' Valid, 'i' Invalid no overlaps, 'V' Invalid with a covering Valid prefix, 'U' Invalid with a covering Unknown prefix. + Introducing pmgrpcd.py, written in Python, a daemon to handle gRPC- based Streaming Telemetry sessions and unmarshall GPB data. Code was mostly courtesy by Matthias Arnold ( @tbearma1 ). This is in addition (or feeding into) pmtelemetryd, written in C, a daemon to handle TCP/UDP-based Streaming Telemetry sessions with JSON-encoded data. + pmacctd, uacctd: added support for CFP (Cisco FabricPath) and Cisco Virtual Network Tag protocols. + print plugin: added 'custom' to print_output. This is to cover two main use-cases: 1) use JSON or Avro encodings but fix the format of the messages in a custom way and 2) use a different encoding than JSON or Avro. See also example in examples/custom and new directives print_output_custom_lib and print_output_custom_cfg_file. The patch was courtesy by Edge Intelligence ( @edge-intelligence ). + Introducing mpls_pw_id aggregation primitive and mpls_pw_id key in pre_tag_map to filter on signalled L2 MPLS VPN Pseudowire IDs. + BGP daemon: added bgp_disable_router_id knob to enable/disable BGP Router-ID check, both at BGP OPEN time and BGP lookup. Useful, for example, in scenarios with split BGP v4/v6 AFs over v4/v6 transports. + BGP, BMP daemons: translate origin attribute numeric value into IGP (i), EGP (e) and Incomplete (u) strings. + plugins: added new plugin_exit_any feature to make the daemon bail out if any (not all, which is the default behaviour) of the plugins exits. + maps_index: improved selection of buckets for index hash structure by picking the closest prime number to the double of the entries of the map to be indexed in order to achieve better elements dispersion and hence better performances. + nfacctd: added support for IPFIX templateId-scoped (IE 145) sampling information. + pmacctd, uacctd, sfacctd, nfacctd: added a -M command-line option to set *_markers (ie. print_markers) to true and fixed -A command-line option to set print_output_file_append to align to true/false. ! fix, BGP, BMP, Streaming Telemetry daemons: improved sequencing of dump events by assigning a single sequence number per event (ie. for streaming pipeline scenarios in order to reduce correlation with dump_init/dump_close messages). Also amount of record dumped was added to the close message. ! fix, BGP, BMP, Streaming Telemetry daemons: removed hierarchical json_decref() since json_object_get() borrows reference. This was occasionaly leading to SEGVs. ! fix, uacctd: dynamically allocate jumbo_container buffer size as packets larger than 10KB, previous static allocation, would lead to crashes. ! fix, nfacctd: wired (BGP, BMP, ISIS, etc.) lookups to the NEL/NSEL use-case. ! fix, nfacctd: search for IE 408 (dataLinkFrameType) was leading to SEGVs. Also improved handling of variable-length IPFIX templates. ! fix, BMP daemon: solved an occasional truncation of the last message in a packet. ! fix, BGP daemon: when processing bgp_daemon_md5_file, ipv4 addresses were incorrectly translated to ipv4-mapped ipv6 ones as a result of which TCP-MD5 hashes were not correctly bound to sockets. ! fix, BGP daemon: improved label-unicast and mpls-vpn SAFIs handling (some bogus messages, multiple labels, etc.). ! fix, BGP daemon: introduced PREFIX_STRLEN to make enough room for prefix2str() calls (before unsufficient INET6_ADDRSTRLEN was used). ! fix, BMP daemon: improved handling of ADD-PATH capability. ! fix, plugins: an incorrect evaluation in P_cache_attach_new_node did make possible to buffer overrun in plugins cache allocation. This was found related to a "[..]: Assertion `!cache_ptr->stitch' failed." daemon bail-out message. ! fix, plugins: if pidfile directive was enabled, exit_gracefully() was mistakenly deleting the plugin pidfile when called by a child process (ie. writer, dumper, etc.). ! fix, plugins: when taking exit_gracefully(), if the process is marked as 'is_forked', just exit and don't perform extra ops in exit_all() or exit_plugin(). ! fix, plugins: re-evaluate dynamic tables/files name if *_refresh_time is different than *_history period. ! fix, SQL plugins: a missing 'AND' was making SQL statements related to src_host_coords and dst_host_coords fail. ! fix, GeoIPv2: if no match is returned by libmaxminddb, return O1 code (Other Country) instead of a null value. ! fix, flow_to_rd_map: mpls_vpn_id was not working when maps_index was enabled. Also partly re-written mpls_vpn_id handler. ! fix, nfprobe plugin: serialize_bin() function introduced for correct serialization of custom primitives defined with 'raw' semantics. ! fix, PostgreSQL plugin: testing for presence of PQlibVersion() in libpq to prevent compiling issues (ie. on CentOS 6). ! fix, MySQL plugin: including mysql_version.h to compile successfully against newer MariaDB releases. ! fix, nDPI classification: send log message if 'class' primitive is selected but nDPI is not compiled in; also updated code to follow API changes in versions >= 2.6 of the library. Dropped support for versions < 2.4. ! fix, sfprobe plugin: added (and documented) conditional for optional export of classification info. ! fix, aggregate_primitives: field_type is now also allowed for pmacctd and uaccd daemons so that it can be used for NetFlow v9/IPFIX export (nfprobe plugin) purposes. ! fix, pre_tag_map: if no 'ip' keyword is specified, an entry of the map gets recirculated in order to be set for both v4 and v6 maps. If a 'set_label' is also specified, it was causing a SEGV. Now the label is correctly copied in case of recirculation. ! fix, zmq_common.c: added option for non-blocking p_zmq_send_bin() as otherwise program would block in case of no consumers (main use-case: flow replication over ZeroMQ queues); as a result, a generous hwm value was added on both sides of these queues. ! fix, zmq_common.c: ZAP socket moved inside thread to prevent failed assert() when compiling with gcc7/gcc8. Also a single user/password auto-generated combination is used for all plugins. ! fix, signals.c: SIGUSR1 handler for nfacctd and nfacctd is changed to syncronous in order to prevent race conditions. Also, in pmacctd, upon sending SIGUSR1, stats were not printed when reading packets from a pcap_interfaaces_map. ! fix, plugin_cmn_json.c: if leaving protocols numerical (ie. proto, tunnel_proto primitives), convert them to string-represented numbers for data consistency for consumers. ! fix, util.c: open_output_file(), if file exists and it's a FIFO then set O_NONBLOCK when opening. ! fix, pretag.c: pretag_index_report() was reporting incorrect info of the hash structure built for the maps_index feature. Its format was has also changed to be better parseable. ! fix, compile time warnings: several warnings were addressed including but not restricted to -Wformat ones. Also an annotation was added to the Log function to inform the compiler it's a printf-style function, allowing it to give warnings for argument mismatches. - --enable-ipv6 configure script switch has been deprecated and, as a result, IPv6 support was made mandatory. - BGP daemon: removed unused pathlimit field from bgp_attr structure. - pmacct client: removed deprecated SYM field from from formatted and CSV headers. - Build with support for * ZeroMQ * Maxmind GeoIP DB v2 ------------------------------------------------------------------- Thu Dec 20 08:46:10 UTC 2018 - mardnh@gmx.de - Don't enable support for nDPI by default ------------------------------------------------------------------- Mon Dec 17 10:27:58 UTC 2018 - Jan Engelhardt <jengelh@inai.de> - Trim filler wording from description. ------------------------------------------------------------------- Mon Nov 26 18:57:52 UTC 2018 - mardnh@gmx.de - Drop support for older distributions - Update to version 1.7.2 + nfacctd, sfacctd: added Kafka broker among the options to receive NetFlow/IPFIX, sFlow data from. Host, port and topic should all be specified along with an optional config file to pass to librdkafka. + nfacctd, sfacctd, pmtelemetryd: added ZeroMQ queue among the options to receive NetFlow/IPFIX, sFlow or Streaming Telemetry data from. An IP address and port should be specified. + nfacctd, sfacctd: added sampling_direction to the set of supported primitives, valid values being ingress, egress and unknown. + nfacctd, sfacctd: stats, ie. amount of NetFlow/IPFIX or sFlow packets received per router, are now available when in tee mode. Stats can be retrieved via a SIGUSR1 UNIX signal. + pcap_savefile_replay: a feature to replay content for the specified amounf of time when reading from a pcap_savefile. + pre_tag_map: added several new keys: src_net and dst_net (to tag on source and destination IP prefixes respectively), bgp_nexthop (to tag on BGP nexthop) and nat_event. + BGP daemon: added bgp_lrgcomm_pattern feature to filter large BGP communities (in addition to existing equivalent knobs to filter on standard and extended communities). + BMP, Streaming Telemetry daemons: msglog_file and dump_file config directives now offer $bmp_router, $bmp_router_port, $telemetry_node and $telemetry_node_port variables. + BGP, BMP, Streaming Telemetry daemons: added BGP, BMP and Streaming Telemetry exporter TCP/UDP port as variable for dump/log filenames (to better support NAT traversal scenarios). + BGP, BMP daemons: added message sequencing to both BGP and BMP dumps (bgp_table_dump_*, bmp_dump_*). If dumping and logging are enabled in parallel then sequencing the dumps allows for check pointing at regular time intervals. + BMP daemon: implemented draft-hsmit-bmp-extensible-routemon-msgs for a tlv-based encoding of route-monitoring messages with a new message type. + Streaming Telemetry daemon: added sample decoders for gRPC / GPB for Cisco and Huawei platforms, written in Python. Telemetry data is decoded using vendor-supplied proto files and output in JSON format in a ZeroMQ queue - suitable for ingestion in pmtelemetryd. Docs and sample code is available in the telemetry/ directory. This is all in addition to TCP/UDP transports and JSON encoding supported natively in pmtelemetryd. + kafka plugin: introduced support for Confluent Schema Registry via libserdes. A registry can be supplied via kafka_avro_schema_registry config directive; the schema is generated automatically. The feature enables validation of data passed through a Kafka broker and uses Avro encoding. + kafka plugin: added $in_iface key (input interface) to the set of variables supported by kafka_partition_key. Extremely useful when coupled to $peer_src_ip in some scenarios. + print, IMT plugins: separator for CSV format can now be space (\s) or tab (\t). + tee plugin: added Kafka broker among the emitters. kafka_broker and kafka_topic knobs are now available in the tee_receivers map and a tee_kafka_config_file directive allows to define a file with config to pass to librdkafka. + tee plugin: added ZeroMQ queue among the emitters. zmq_address knob defines the queue IP address and port to emit to. + tee plugin: introducing support for complex pre_tag_map when doing replication of NetFlow/IPFIX (sFlow replication had already this). With this feature flows are individually evaluated against supplied filters (input interface, BGP next-hop, etc.) and (not) replicated accordingly. + GeoIP v2: added support for latitude and longitude primitives via src_host_coords and dst_host_coords knobs. This is in addition to existing country and pocode supports. + files_uid, files_gid: now also user and group strings are accepted. This is in addition to user and group IDs. ! fix, nfacctd: NF_evaluate_flow_type() improved to not detect Cisco ASA flows (ie. those including initiator and responder octets) as events. Also improved sanity checking of received NetFlow v9/IPFIX data and options templates and reviwed modulo functions and improved template hashing. ! fix, BGP, BMP, Streaming Telemetry daemons: improved log sequencing by handling counter wrap-up more gracefully. Also a log sequencing API was developed to improve code re-use. ! fix, BGP daemon: added check for duplicate Router-IDs at BGP OPEN parsing time. If a duplicate is detected, the session BGP OPENing of the new session is dropped. ! fix, BGP daemon: ADD-PATH capability was checked only in the first AFI/SAFI and was being set in the reply for last AFI/SAFI RECEIVE(1) if first included SEND(2) or SEND-RECEIVE(3). Thanks to Markus Weber ( @FvDxxx ) for his patch. ! fix, BGP daemon: upon route lookup, don't perform ADD-PATH logics if no PATH-ID (even if ADD-PATH capability is announced by the peer). Thanks to Camilo Cardona ( @jccardonar ) for his support solving the issue. ! fix, BGP daemon: graceful handling of invalid AS-PATH segment types (ie. AS-PATH in BGP UPDATE inconsistent with capabilities passed in BGP OPEN) in order to avoid SEGVs. ! fix, pmtelemetryd: improved support for UDP timeouts. Also reviewed natively supported encodings: removed zjson and GPB was moved to pre- processors (with samples available in telemetry/decoders directory). ! fix, pmtelemetryd: no dump_init / dump_close events sequencing since all messages are sequenced anyway (consistency with other daemons). ! fix, kafka_common.c: now destroying both config and topic config as part of p_kafka_close() in order to avoid memory leaks. Also, port is omitted from broker string if not passed to p_kafka_set_broker(). And finally output queue length checks in p_kafka_check_outq_len() have been relaxed (to counter temporary hickups that need more patience). ! fix, kafka plugin: kafka_partition default was zero (that is, a valid partition number) instead of -1 (RD_KAFKA_PARTITION_UA or unassigned) which allows librdkafka to attach a partitioner. ! fix, SQL plugins: sql_table_schema is honoured even if sql_table_name is non-dynamic. This is to cover cases where the table is rotated externally. ! fix, mysql plugin: my_bool replaced with bool. The plugin now does compile against MySQL 8.0. Also added inclusion of stdbool.h as on some systems bool is not defined. Improved overall probing for MySQL headers. ! fix, pgsql plugin: sql_recovery_backup_host was not being honoured. PG_create_backend() now composes a proper conn_string. ! fix, print plugin: increase successful queries number, QN, only if the output file was successfully opened. ! fix, zmq_common.c: moved ZAP socket initialization inside the ZAP handler. See: https://github.com/zeromq/libzmq/issues/3313 . ! fix, util.c: length checks in handle_dynname_internal_strings() were reviewed. Existings were not working in absence of starting/trailing non-variable strings. ! fix, util.c: use lockf() instead of more problematic flock(). Thanks to Yuri Lachin ( @yuyutime ) and Miki Takata ( @mikiT ) for their support. ! fix, util.c: in compose_timestamp() pad usecs and use "%ld" since time fields are signed longs. Thanks to @raymondrussell for the patch. ! fix, ndpi_util.c: a protocol bitmask is now set in order to increase match rate. Patch is courtesy by @rsolsn. ! fix, compile time warnings: several warnings were addressed including but not restricted to -Wreturn-time, -Wunused-variable, implicit func declarations, -Wformat-extra-args, -Wunused-label, -Wunused-value, -Wunused-function, sbrk calls, -Wpointer-to-int-cast, -Wparentheses and -Wint-to-pointer-cast. ! fix, dangerous uninitialized values: net_aggr.c, pmacct.c: in merge() argument with non-NULL attribute could be passed NULL; bmp_msg.c: in bmp_process_msg_route_monitor() bdata.tstamp could be uninitialized; sfprobe_plugin.c: calloc() return value (possibly null) was not being checked; sflow_agent.c: uninitialized ret value in sfl_agent_init() could lead to undefined bind() error behaviour. ! fix, thread_pool.c: reviewed logics in deallocate_thread_pool() and solved a minor memory leak in allocate_thread_pool(). - pmacctd: removed support for FDDI - nfacctd: discontinued support for NetFlow v1, v7 and v8 collection and replication. - pre_tag_map: matching on 'sampling_rate' is not supported anymore as a sampling_rate primitive is now available; the 'return' feature to return matched data before completing the map workflow has started being obsoleted (retired from docs but still available). - plugin_pipe_check_core_pid: deprecating feature given RabbitMQ and Kafka are not supported anymore for internal message delivery. - tee plugin: obsoleted tee_dissect_send_full_pkt knob, entire packets are now replicated only if no pre_tag_map or a simple pre_tag_map is defined. - nfprobe plugin: removed support for NetFlow v1 export. ------------------------------------------------------------------- Sun May 6 14:10:10 UTC 2018 - mardnh@gmx.de - update to version 1.7.1 + pmbgpd: introduced a BGP connect feature meant to map BGP peers (ie. PE routers) to BGP collectors (ie. nfacctd, sfacctd) via a standalone BGP daemon (pmbgpd). The aim is to facilitate operations when re-sizing/re-balancing the collection infrastructure without impacting (ie. re-configuring) BGP peers. bgp_daemon_xconnect_map expects full pathname to a file where cross-connects are defined; mapping works only against the IP source address and not the BGP Router ID, only 1:1 relationships can be formed (ie. this is about cross-connecting, not replication) and only one session per BGP peer is supported (ie. multiple BGP agents are running on the same IP address or NAT traversal scenarios are not supported [yet]). A sample map is provided in 'examples/bgp_xconnects.map.example'. + pmbgpd: introduced a BGP Looking Glass server allowing to perform queries, ie. lookup of IP addresses/prefixes or get the list of BGP peers, against available BGP RIBs. The server is asyncronous and uses ZeroMQ as transport layer to serve incoming queries. Sample C/Python LG clients are available in 'examples/lg'. A sample LG server config is available in QUICKSTART. Request/Reply Looking Glass formats are documented in 'docs/LOOKING_GLASS_FORMAT'. + pmacctd: a single daemon can now listen for traffic on multiple interfaces via a polling mechanism. This can be configured via a pcap_interfaces_map feature (interface/pcap_interface can still be used for backward compatiblity to listen on a single interface). The map allows to define also ifindex mapping and capturing direction on a per-interface basis. The map can be reloaded at runtime via a USR2 signal and a sample map is in examples/pcap_interfaces.map.example. + Kafka plugin: dynamic partitioning via kafka_partition_dynamic and kafka_partition_key knobs is introduced. The Kafka topic can contain variables, ie. $peer_src_ip, $src_host, $dst_port, $tag, etc., which are all computed when data is purged to the backend. This feature is in addition to the existing kafka_partition feature which allows to rely on the built-in Kafka partitioning to assign data statically to one partition or rely dynamically on the default partitioner. The feature is courtesy by Corentin Neau / Codethink ( @weyfonk ). + Introduced rfc3339 formatted timestamps: in logs, ie. UTC timezone represented as yyyy-MM-ddTHH:mm:ss(.ss)Z; for aggregation primitives the timestamps_rfc3339 knob can be used to enable this feature (left disabled by default for backward compatibility). + timestamps_utc: new knob to decode timestamps to UTC timezone even if the Operating System is set to a different timezone. On the goods of running a system set to UTC please read Q18 of FAQS. + sfacctd: implemented mpls_label_top, mpls_label_bottom and mpls_stack_depth primitives decoded from sFlow flow sample headers. Thanks to David Barroso ( @dbarrosop ) for his support. + nfacctd: added support for IEs 130 (exporterIPv4Address) and 131 (exporterIPv6Address) when passed as part of NetFlow v9/IPFIX option packets (these IEs were already supported when passed in flow data). Also added support for IE 351 (dataLinkFrameSection) which carries the initial portion of a sampled raw packet headers (a-la sFlow). This was tested working against a Cisco NCS 5k platform. + nfprobe plugin: added a new nfprobe_dont_cache knob allowing to disable caching and summarisation of flows (essentially letting the NetFlow/IPFIX probe behave like a sFlow probe). + nfprobe plugin: added support for MPLS_LABEL_1, NetFlow v9/IPFIX IE 70; improved support for BGP next-hop IE 18 and 63. Also support for IE 130/131 vi NetFlow v9/IPFIX Options was added. + sfprobe plugin: added sfprobe_source_ip knob to define the local IP address from which sFlow datagrams are exported; improved support for BGP next-hop. + nfacctd, sfacctd, BGP, BMP, Streaming Telemetry daemons: on Linux, if supported, use SO_REUSEPORT for the listening socket (added to existing SO_REUSEADDR option). + nfacctd, sfacctd: introduced new 'export_proto_sysid' primitive to give visibility to NetFlow v5/v8 engine_id / NetFlow v9 source ID / IPFIX Obs Domain ID / sFlow agentSubID. + nfacctd, sfacctd: extended nDPI support to NetFlow v9/IPFIX packets with IE 315 (dataLinkFrameSection) and sFlow v5 packets with header section. + nfacctd, sfacctd: extended custom primitives definition framework, aggregate_primitives, to NetFlow v9/IPFIX packets with IE 315 (dataLinkFrameSection) and sFlow v5 sampled headers section. + nfacctd, sfacctd: added per-collector packets and bytes counts to stats emitted via SIGUSR1. Also the output was made more formal (so to be more easily parsed) and is documented in the UPGRADE notes. + nfacctd, pmacctd, sfacctd: pcap_savefile_delay feature introduced to sleep for the supplied amount of seconds before playing a given pcap_savefile. Useful, for example, to let BGP/BMP sessions come up so that routing data is available for correlation when processing data in the trace. + Kafka plugin: configuring statistics.interval.ms to a positive value in a kafka_config_file makes now librdkafka log plenty of internal metrics. + BGP daemon: added support for Extended BGP Administrative Shutdown Communication (draft-snijders-idr-rfc8203bis-00). + BMP daemon: added support for draft-ietf-grow-bmp-adj-rib-out-01 and draft-ietf-grow-bmp-loc-rib-01. As a result of that, Route Monitor log messages now contain indication of is_out and is_filtered. + BMP daemon: added support for stats reports 9, 10, 11, 12 and 13 and descriptions for the different Peer Types and and Peer Down reasons. Finally, indication of is_post is now making to Route Monitor log messages. + plugin_pipe_zmq: introduced plugin_pipe_zmq_hwm (high water mark) knob to control the maximum amount of messages than can be stored in the ZeroMQ queue. + [ns]facctd_allow_file: the map is now made reloadable at runtime via SIGUSR2 and accepts IPv4/IPv6 prefixes increasing its scale (before it was only accepting individual IP addresses). + pmacctd: added support for IPv6, MPLS for DLT_LINUX_SLL captures. Thanks to David Barroso ( @dbarrosop ) for his support. + uacctd: added a global 'direction' knob to give visibility of data capturing direction, ie. in/out. Useful for pre_tag_map use. + MySQL plugin: added sql_port knob in order to specify non-default ports for connecting to the database. Patch is courtesy by Vadim Tkachenko ( @vadimtk ). ! fix, plugins: getppid() parent process health check improved so to work in Docker environments not assuming anymore parent PID is 1. Patch is courtesy by Hidde van der Heide ( @hvanderheide ). ! fix, plugins: imposing a budget for received messages (100) so to preserve fairness of other operations (ie. time keeping, bucketing, reloading maps, etc.) and prevent starvations. ! fix, zmq_common.c: retry if zmq_getsockopt() for ZMQ_EVENTS returns EINTR. Thanks to Wouter de Jong for his support solving the issue. ! fix, plugins: when executing triggers, the first argument passed to execv() should be the path to the invoked executable to prevent execv(3) to fail and return EFAULT on OpenBSD. Patch is courtesy by @higgsd. ! fix, BGP daemon: improved support of multiple capabilities per optional parameter in the OPEN message. Also add-path capability is now advertised if neighbor supports send/receive (previously it was sent back on send only) of such capability. Thanks to Radu Anghel ( @cozonac ) for his support. ! fix, BGP daemon: upon route lookup, don't perform ADD-PATH logics if no PATH-ID (even if ADD-PATH capability is announced by the peer). Thanks to Camilo Cardona ( @jccardonar ) for his support solving the issue. ! fix, BGP daemon: wrong type 2 32-bit ASN Route Distinguisher was defined in network.h. Thanks to Thomas Graf for reporting the issue. ! fix, BGP, BMP daemons: lookup of BGP-LU entries is now performed against the correct RIB. ! fix, BMP daemon: the BMP thread is now made mutually exclusive with the BGP one (until an use-case needs to run them both). This is to potentially prevent BGP and BMP information to interfere with each other when correlated. Also the 'bmp' keyword was added for *_as and *_net config directives (ie. nfacctd_as, nfacctd_net). Thanks to Juan Camilo Cardona ( @jccardonar ) for his support. ! fix, BMP daemon: improved correlation of BMP data with traffic data by supporting a replication use-case (the BMP exporter is a route -server rather than an actual Edge Router) upon lookup. Thanks to Juan Camilo Cardona ( @jccardonar ) for his support. ! fix, BMP daemon: in bgp_peer_cmp() and bgp_peer_host_addr_cmp() the comparison function has been changed from generic memcmp() to a more specific host_addr_cmp() as paddings were giving issues. Thanks to Juan Camilo Cardona ( @jccardonar ) for reporting the issue. ! fix, BMP daemon: a pm_tdestroy call in bmp_peer_close() was leading to SEGV under certain conditions by not NULL'ing all pointers. Thanks to Juan Camilo Cardona ( @jccardonar ) for reporting the issue. ! fix, nfacctd: prevent time calculations to underflow in cases in which sysUptime < first or last flow switched timestamps in NetFlow v5. Patch is courtesy by David Steinn Geirsson ( @dsgwork ). ! fix, nfacctd: in the context of aggregate_primitives, now enforcing terminating the zero when decoding variable-length IEs when applying string semantics. ! fix, nfprobe: changed ifIndex fields from u_int16_t to u_int32_t in order to prevent overflows and aligning to the rest of structs. ! fix, MySQL plugin: minor code revisions to restore compiling against MariaDB 10.2. ! fix, sql_common.c: increased read_SQLquery_from_file() buffer size so that sql_table_schema can be fed with longer CREATE TABLE statements. ! fix, print, SQL plugins: post_tag, post_tag2 support was added to sql_table and print_output_file. Also for Kafka, RabbitMQ plugins kafka_topic and amqp_routing_key variables support was harmonized with print and SQL plugins (ie. $pre_tag renamed to $tag), see UPGRADE notes. ! fix, SQL plugins: sql_startup_delay was not being honored when sql_trigger_exec was defined without a sql_trigger_time resulting in empty environment variables being passed to the triggered script. Thanks to Johannes Maybaum for his support resolving the issue. ! fix, pkt_handlers.c: tmp_asa_bi_flow value was ignored when applied to a specific plugin. ! fix, util.c: when data timestamp is not available, dynamic file and table names variables were populated with a 1-Jan-1970 date. Now the current timestamp is used instead as last resort. Patch is courtesy by Ivan F. Martinez ( @ivanfmartinez ). ! fix, addr.c: host_addr_mask_sa_cmp() and str_to_addr_mask() network mask computation for IPv6 addresses was wrong. allow_file feature was affected. ! fix, build system: several patches committed to the build system to simplify libraries probing, make sure to bail out upon error. Also now a minimum required version is imposed to almost all libraries. - --enable-threads / --disable-threads: removed the configure switch that was allowing to compile pmacct even when no pthreads library was available on a system. From now on support for threads is mandatory. - BGP daemon: offline code, ie. bgp_daemon_offline_* config directives, has been deprecated in favor of other approaches, ie. BGP Looking Glass and BGP Xconnects. - pkt_len_distrib: the primitive, which was meant to bucket packet / flow / sample lengths in a distribution has been obsoleted. - Remove patch: * pmacct-pgsql-fix-header-detection-without-autoreconf.diff ------------------------------------------------------------------- Sun Oct 22 09:22:28 UTC 2017 - mardnh@gmx.de - update to version 1.7.0 + ZeroMQ integration: by defining plugin_pipe_zmq to 'true', ZeroMQ is used for queueing between the Core Process and plugins. This is in alternative to the home-grown circular queue implementation (ie. plugin_pipe_size). plugin_pipe_zmq_profile can be set to one value of { micro, small, medium, large, xlarge } and allows to select among a few standard buffering profiles without having to fiddle with plugin_buffer_size. How to compile, install and operate ZeroMQ is documented in the "Internal buffering and queueing" section of the QUICKSTART document. + nDPI integration: enables packet classification, replacing existing L7-layer project integration, and is available for pmacctd and uacctd. The feature, once nDPI is compiled in, is simply enabled by specifying 'class' as part of the aggregation method. How to compile install and operate nDPI is documented in the "Quickstart guide to packet classification" section of the QUICKSTART document. + nfacctd: introduced nfacctd_templates_file so that NetFlow v9/IPFIX templates can be cached to disk to limit the amount of lost packets due to unknown templates when nfacctd (re)starts. The implementation is courtesy by Codethink Ltd. + nfacctd: introduced support for PEN on IPFIX option templates. This is in addition to already supported PEN for data templates. Thanks to Gilad Zamoshinski ( @zamog ) for his support. + sfacctd: introduced new aggregation primitives (tunnel_src_host, tunnel_dst_host, tunnel_proto, tunnel_tos) to support inner L3 layers. Thanks to Kaname Nishizuka ( @__kaname__ ) for his support. + nfacctd, sfacctd: pcap_savefile and pcap_savefile_wait were ported from pmacctd. They allow to process NetFlow/IPFIX and sFlow data from previously captured packets; these also ease some debugging by not having to resort anymore to tcpreplay for most cases. + pmacctd, sfacctd: nfacctd_time_new feature has been ported so, when historical accounting is enabled, to allow to choose among capture time and time of receipt at the collector for time-binning. + nfacctd: added support for NetFlow v9/IPFIX field types #130/#131, respectively the IPv4/IPv6 address of the element exporter. + nfacctd: introduced nfacctd_disable_opt_scope_check: mainly a work around to implementations not encoding NetFlow v9/IPIFX option scope correctly, this knob allows to disable option scope checking. Thanks to Gilad Zamoshinski ( @zamog ) for his support. + pre_tag_map: added 'source_id' key for tagging on NetFlow v9/IPFIX source_id field. Added also 'fwdstatus' for tagging on NetFlow v9/ IPFIX information element #89: this implementation is courtesy by Emil Palm ( @mrevilme ). + tee plugin: tagging is now possible on NetFlow v5-v8 engine_type/ engine_id, NetFlow v9/IPFIX source_id and sFlow AgentId. + tee plugin: added support for 'src_port' in tee_receivers map. When in non-transparent replication mode, use the specified UDP port to send data to receiver(s). This is in addition to tee_source_ip, which allows to set a configured IP address as source. + networks_no_mask_if_zero: a new knob so that IP prefixes with zero mask - that is, unknown ones or those hitting a default route - are not masked. The feature applies to *_net aggregation primitives and makes sure individual IP addresses belonging to unknown IP prefixes are not zeroed out. + networks_file: hooked up networks_file_no_lpm feature to peer and origin ASNs and (BGP) next-hop fields. + pmacctd: added support for calling pcap_set_protocol() if supported by libpcap. Patch is courtesy by Lennert Buytenhek ( @buytenh ). + pmbgpd, pmbmpd, pmtelemetryd: added a few CL options to ease output of BGP, BMP and Streaming Telemetry data, for example: -o supplies a b[gm]p_daemon_msglog_file, -O supplies a b[gm]p_dump_file and -i supplies b[gm]p_dump_refresh_time. + kafka plugin: in the examples section, added a Kafka consumer script using the performing confluent-kafka-python module. ! fix, BGP daemon: segfault with add-path enabled peers as per issue #128. Patch is courtesy by Markus Weber ( @FvDxxx ). ! fix, print plugin: do not update link to latest file if cause of purging is a safe action (ie. cache space is finished. Thanks to Camilo Cardona ( @jccardonar ) for reporting the issue. Also, for the same reason, do not execute triggers (ie. print_trigger_exec). ! fix, nfacctd: improved IP protocol check in NF_evaluate_flow_type() A missing length check was causing, under certain conditions, some flows to be marked as IPv6. Many thanks to Yann Belin for his support resolving the issue. ! fix, print and SQL plugins: optimized the cases when the dynamic filename/table has to be re-evaluated. This results in purge speed gains when the dynamic part is time-related and nfacctd_time_new is set to true. ! fix, bgp_daemon_md5_file: if the server socket is AF_INET and the compared peer address in MD5 file is AF_INET6 (v4-mapped v6), pass it through ipv4_mapped_to_ipv4(). Also if the server socket is AF_INET6 and the compared peer addess in MD5 file is AF_INET, pass it through ipv4_to_ipv4_mapped(). Thanks to Paul Mabey for reporting the issue. ! fix, nfacctd: improved length checks in resolve_vlen_template() to prevent SEGVs. Thanks to Josh Suhr and Levi Mason for their support. ! fix, nfacctd: flow stitching, improved flow end time checks. Thanks to Fabio Bindi ( @FabioLiv ) for his support resolving the issue. ! fix, amqp_common.c: amqp_persistent_msg now declares the RabbitMQ exchange as durable in addition to marking messages as persistent; this is related to issue #148. ! fix, nfacctd: added flowset count check to existing length checks for NetFlow v9/IPFIX datagrams. This is to avoid logs flooding in case of padding. Thanks to Steffen Plotner for reporting the issue. ! fix, BGP daemon: when dumping BGP data at regular time intervals, dump_close message contained wrongly formatted timestamp. Thanks to Yuri Lachin for reporting the issue. ! fix, MySQL plugin: if --enable-ipv6 and sql_num_hosts set to true, use INET6_ATON for both v4 and v6 addresses. Thanks to Guy Lowe ( @gunkaaa ) for reporting the issue and his support resolving it. ! fix, 'flows' primitive: it has been wired to sFlow so to count Flow Samples received. This is to support Q21 in FAQS document. ! fix, BGP daemon: Extended Communities value was printed with %d (signed) format string instead of %u (unsigned), causing issue on large values. ! fix, aggregate_primitives: improved support of 'u_int' semantics for 8 bytes integers. This is in addition to already supported 1, 2 and 4 bytes integers. ! fix, pidfile: pidfile created by plugin processes was not removed. Thanks to Yuri Lachin for reporting the issue. ! fix, print plugin: checking non-null file descriptor before setvbuf in order to prevent SEGV. Similar checks were added to prevent nulls be input to libavro calls when Apache Avro output is selected. ! fix, SQL plugins: MPLS aggregation primitives were not correctly activated in case sql_optimize_clauses was set to false. ! fix, building system: reviewed minimum requirement for libraries, removed unused m4 macros, split features in plugins (ie. MySQL) and supports (ie. JSON). ! fix, sql_history: it now correctly honors periods expressed is 's' seconds. ! fix, BGP daemon: rewritten bgp_peer_print() to be thread safe. ! fix, pretag.h: addressed compiler warning on 32-bit architectures, integer constant is too large for "long" type. Thanks to Stephen Clark ( @sclark46 ) for reporting the issue. - MongoDB plugin: it is being discontinued since the old Mongo API is not supported anymore and there has never been enough push from the community to transition to the new/current API (which would require a rewrite of most of the plugin). In this phase-1 the existing MongoDB plugin is still available using 'plugins: mongodb_legacy' in the configuration. - Packet classification basing on the L7-filter project is being discontinued (ie. 'classifiers' directive). This is being replaced by an implementation basing on the nDPI project. As part of this also the sql_aggressive_classification knob has been discontinued. - tee_receiver was part of the original implementation of the tee plugin, allowing to forward to a single target and hence requiring multiple plugins instantiated, one per target. Since 0.14.3 this directive was effectively outdated by tee_receivers. - tmp_net_own_field: the knob has been discontinued and was allowing to revert to backward compatible behaviour of IP prefixes (ie. src_net) being written in the same field as IP addresses (ie. src_host). - tmp_comms_same_field: the knob has been discontinued and was allowing to revert to backward compatible behaviour of BGP communities (standard and extended) being writeen all in the same field. - plugin_pipe_amqp and plugin_pipe_kafka features were meant as an alternative to the homegrown queue solution for internal messaging, ie. passing data from the Core Process to Plugins, and are being discontinued. They are being replaced by a new implementation, plugin_pipe_zmq, basing on ZeroMQ. - plugin_pipe_backlog was allowing to keep an artificial backlog of data in the Core Process so to maximise bypass poll() syscalls in plugins. If home-grown queueing is found limiting, instead of falling back to such strategies, ZeroMQ queueing should be used. - pmacctd: deprecated support for legacy link layers: FDDI, Token Ring and HDLC. ------------------------------------------------------------------- Sat Apr 22 18:12:00 UTC 2017 - mardnh@gmx.de - update to version 1.6.2 + BGP, BMP daemons: introduced support for BGP Large Communities IETF draft (draft-ietf-idr-large-community). Large Communities are stored in a variable-length field. Thanks to Job Snijders ( @job ) for his support. + BGP daemon: implemented draft-ietf-idr-shutdown. The draft defines a mechanism to transmit a short freeform UTF-8 message as part of a Cease NOTIFICATION message to inform the peer why the BGP session is being shutdown or reset. Thanks to Job Snijders ( @job ) for his support. + tee plugin, pre_tag_map: introduced support for inspetion of specific flow primitives and selective replication over them. The primitives supported are: input and output interfaces, source and destination MAC addresses, VLAN ID. The feature is now limited to sFlow v5 only. Thanks to Nick Hilliard and Barry O'Donovan for their support. + Added src_host_pocode and dst_host_pocode primitives, pocode being a compact and (de-)aggregatable (easy to identify districts, cities, metro areas, etc.) geographical representation, based on the Maxmind v2 City Database. Thanks to Jerred Horsman for his support. + Kafka support: introduced support for user-defined (librdkafka) config file via the new *_kafka_config_file config directives. Full pathname to a file containing directives to configure librdkafka is expected. All knobs whose values are string, integer, boolean are supported. + AMQP, Kafka plugins: introduced new directives kafka_avro_schema_topic, amqp_avro_schema_routing_key to transmit Apache Avro schemas at regular time intervals. The routing key/topic can overlap with the one used to send actual data. + AMQP, Kafka plugins: introduced support for start/stop markers when encoding is set to Avro (ie. 'kafka_output: avro'); also Avro schema is now embedded in a JSON envelope when sending it via a topic/routing key (ie. kafka_avro_schema_topic). + print plugin: introduced new config directive avro_schema_output_file to save the Apache Avro schema in a separate file (it was only possible to have it combined at the beginning of the data file). + BGP daemon: introduced a new bgp_daemon_as config directive to set a LocalAS which could be different from the remote peer one. This is to establish an eBGP session instead of a iBGP one (default). + flow_to_rd_map: introduced support for mpls_vpn_id. In NetFlow/IPFIX this is compared against Field Types #234 and #235. + sfacctd: introduced support for sFlow v2/v4 counter samples (generic, ethernet, vlan). This is in addition to existing support for sFlow v5 counters. + BGP, BMP and Streming Telemetry daemons: added writer_id field when writing to Kafka and/or RabbitMQ. The field reports the configured core_proc_name and the actual PID of the writer process (so, while being able to correlate writes to the same daemon, it's also possible to distinguish among overlapping writes). + amqp, kafka, print plugins: harmonized JSON output to the above: added event_type field, writer_id field with plugin name and PID. + BGP, BMP daemons: added AFI, SAFI information to log and dump outputs; also show VPN Label if SAFI is MPLS VPN. + pmbgpd, pmbmpd: added logics to bypass building RIBs if only logging BGP/BMP data real-time. + BMP daemon: added BMP peer TCP port to log and dump outputs (for NAT traversal scenarios). Contextually, multiple TCP sessions per IP are now supported for the same reason. + SQL plugins: ported (from print, etc. plugins) the 1.6.1 re-working of the max_writers feature. + uacctd: use current time when we don't have a timestamp from netlink. We only get a timestamp when there is a timestamp in the skb. Notably, locally generated packets don't get a timestamp. The patch is courtesy by Vincent Bernat ( @vincentbernat ). + build system: added configure options for partial linking of binaries with any selection/combination of IPv4/IPv6 accounting daemons, BGP daemon, BMP daemon and Streaming Telemetry daemon possible. By default all are compiled in. + BMP daemon: internal code changes to pass additional info from BMP per-peer header to bgp_parse_update_msg(). Goal is to expose further info, ie. pre- vs post- policy, when logging or dumping BMP info. ! fix, BGP daemon: introduced parsing of IPv6 MPLS VPN (vpnv6) NLRIs. Thanks to Alberto Santos ( @m4ccbr ) for reporting the issue. ! fix, BGP daemon: upon doing routes lookup, now correctly honouring the case of BGP-LU (SAFI_MPLS_LABEL). ! fix, BGP daemon: send BGP NOTIFICATION out in case of known failures in bgp_parse_msg(). ! fix, kafka_partition, *_kafka_partition: default value changed from 0 (partition zero) to -1 (RD_KAFKA_PARTITION_UA, partition unassigned). Thanks to Johan van den Dorpe ( @johanek ) for his support. ! fix, pre_tag_map: removed constraint for 'ip' keyword for nfacctd and sfacctd maps. While this is equivalent syntax to specifying rules with 'ip=0.0.0.0/0', it allows for map indexing (maps_index: true). ! fix, bgp_agent_map: improved sanity check against bgp_ip for IPv6 addresses (ie. an issue appeared for the case of '::1' where the first 64 bits are zeroed out). Thanks to Charlie Smurthwaite ( @catphish ) for reporting the issue. ! fix, maps_index: indexing now correctly works for IPv6 pre_tag_map entries. That is, those where 'ip', the IP address of the NetFlow/ IPFIX/sFlow exporter, is an IPv6 address. ! fix, pre_tag_map: if mpls_vpn_rd matching condition is specified and maps_index is enabled, PT_map_index_fdata_mpls_vpn_rd_handler() now picks the right (and expected) info. ! fix, pkt_handlers.c: improved definition and condition to free() in bgp_ext_handler() in order to prevent SEGVs. Thanks to Paul Mabey for his support. ! fix, kafka_common.c: removed waiting time from p_kafka_set_topic(). Added docs advicing to create in advance Kafka topics. ! fix, sfacctd, sfprobe: tag and tag2 are now correctly re-defined as 64 bits long. ! fix, sfprobe plugin, sfacctd: tags and class primitives are now being encoded/decoded using enterprise #43874, legit, instead of #8800, that was squatted back in the times. See issue #71 on GiHub for more info. ! fix, sfacctd: lengthCheck() + skipBytes() were producing an incorrect jump in case of unknown flow samples. Replaced by skipBytesAndCheck(). Thanks to Elisa Jasinska ( @fooelisa ) for her support. ! fix, pretag_handlers.c: in bgp_agent_map added case for 'vlan and ...' filter values. ! fix, BGP daemon: multiple issues of partial visibility of the stored RIBs and SEGVs when bgp_table_per_peer_buckets was not left default: don't mess with bms->table_per_peer_buckets given the multi-threaded scenario. Thanks to Dan Berger ( @dfberger ) for his support. ! fix, BGP, BMP daemons: bgp_process_withdraw() function init aligned to bgp_process_update() in order to prevent SEGVs. Thanks to Yuri Lachin for his support. ! fix, bgp_msg.c: Route Distinguisher was stored and printed incorrectly when of type RD_TYPE_IP. Thanks to Alberto Santos ( @m4ccbr ) for reporting the issue. ! fix, bgp_logdump.c: p_kafka_set_topic() was being wrongly applied to an amqp_host structure (instead of a kafka_host structure). Thanks to Corentin Neau ( @weyfonk ) for reporting the issue. ! fix, BGP daemon: improved BGP next-hop setting and comparison in cases of MP_REACH_NLRI and MPLS VPNs. Many thanks to both Catalin Petrescu ( @cpmarvin ) and Alberto Santos ( @m4ccbr ) for their support. ! fix, pmbgpd, pmbmpd: pidfile was not written even if configured. Thanks to Aaron Glenn ( @aaglenn ) for reporting the issue. ! fix, tee plugin: tee_max_receiver_pools is now correctly honoured and debug message shows the replicatd protocol, ie. NetFlow/IPFIX vs sFlow. ! AMQP, Kafka plugins: separate JSON objects, newline separated, are preferred to JSON arrays when buffering of output is enabled (ie. kafka_multi_values) and output is set to JSON. This is due to quicker serialisation performance shown by the Jansson library. ! build system: switched to enable IPv6 support by default (while the --disable-ipv6 knob can be used to reverse the behaviour). Patch is courtesy by Elisa Jasinska ( @fooelisa ). ! build system: given visibility, ie. via -V CL option, into compile options enabled by default (ie. IPv6, threads, 64bit counters, etc.). ! fix, nfprobe: free expired records when exporting to an unavailable collector in order to prevent a memory leak. Patch is courtersy by Vladimir Kunschikov ( @kunschikov ). ! fix, AMQP plugin: set content type to binary in case of Apache Avro output. ! fix, AMQP, Kafka plugins: optimized amqp_avro_schema_routing_key and kafka_avro_schema_topic. Avro schema is built only once at startup. ! fix, cfg.c: improved parsing of config key-values where squared brakets appear in the value part. Thanks to Brad Hein ( @regulatre ) for reporting the issue. Also, detection of duplicates among plugin and core process names was improved. ! fix, misc: compiler warnings: fix up missing includes and prototypes; the patch is courtesy by Tim LaBerge ( @tlaberge ). ! kafka_consumer.py, amqp_receiver.py: Kafka, RabbitMQ consumer example scripts have been greatly expanded to support posting to a REST API or to a new Kafka topic, including some stats. Also conversion of multiple newline-separated JSON objects to a JSON array has been added. Misc bugs were fixed. - remove patcch: pmacct-fix-implicit-pointer-decl.diff ------------------------------------------------------------------- Wed Jul 13 10:22:52 UTC 2016 - mardnh@gmx.de - add systemd scripts - add manpage for pmacct - remove not longer supported build options - enable-v4-mapped - with-pgsql-includes - fix build for older SUSE versions (SLES11SP4, SLES12, OpenSUSE 13.1) - add patch for psql-header detection on SLES11SP4 and openSUSE 13.1 - pmacct-pgsql-fix-header-detection-without-autoreconf.diff ------------------------------------------------------------------- Sat Jun 11 17:50:42 UTC 2016 - mardnh@gmx.de - update to version 1.6.0 + Streamed telemetry daemon: quoting Cisco IOS-XR Telemetry Configuration Guide at the time of this writing: "Streaming telemetry [ .. ] data can be used for analysis and troubleshooting purposes to maintain the health of the network. This is achieved by leveraging the capabilities of machine-to-machine communication. [ .. ]" Streamed telemetry support comes in two flavours: 1) a telemetry thread can be started in existing daemons, ie. sFlow, NetFlow/IPFIX, etc. for the purpose of data correlation and 2) a new daemon pmtelemetryd for standalone consumpton of data. Streamed telemetry data can be logged real-time and/or dumped at regular time intervals to flat-files, RabbitMQ or Kafka brokers. + BMP daemon: introduced support for Route Monitoring messages. RM messages "provide an initial dump of all routes received from a peer as well as an ongoing mechanism that sends the incremental routes advertised and withdrawn by a peer to the monitoring station". Like for BMP events, RM messages can be logged real-time and/or dumped at regular time intervals to flat-files, RabbiMQ and Kafka brokers. RM messages are also saved in a RIB structure for IP prefix lookup. + uacctd: ULOG support switched to NFLOG, the newer and L3 independent Linux packet logging framework. One of the key advantages of NFLOG is support for IPv4 and IPv6 (whereas ULOG was restricted to IPv4 only). The code has been contributed by Vincent Bernat ( @vincentbernat ). + build system: it was modernized so not to rely on specific and old versions of automake and autoconf, as it was the case until 1.5. Among the things, pkg-config and libtool are leveraged and an autogen.sh script is generated. The code has been contributed by Vincent Bernat ( @vincentbernat ). + sfacctd: RabbitMQ and Kafka support was introduced to real-time log and/ or dump at regular time intervals of sFlow counters. This is in addition to existing support for flat-files. + maps_index: several improvements were carried out in the area of indexing of maps: optimizations to pretag_index_fill() and pretag_index_lookup() to improve lookup speeds; optimized id_entry structure, ie. by splitting key and non-key parts, and hashing key in order to consume less memory; added duplicate entry detection (cause of sudden index destruction); pretag_index_destroy() destroys hash keys for each index entry, solving a memory leak issue. Thanks to Job Snijders ( @job ) for his support. + Introduced 'export_proto_seqno' aggregation primitive to report on sequence number of the export protocol (ie. NetFlow, sFlow, IPFIX). This feature may enable more advanced offline analysis of packet loss, out of orders, etc. over time windows than basic online analytics provided by the daemons. + log.c: logging moved from standard output (stdout) to standard error (stderr) so to not conflict with stdout printing of statistics (print plugin). Thanks to Jim Westfall ( @jwestfall69 ) for his support. + print plugin: introduced a new print_output_lock_file config directive to lock standard output (stdout) output so to prevent multiple processes (instances of the same print plugin or different instances of print plugin) overlap output. Thanks to Jim Westfall ( @jwestfall69 ) for his support. + pkt_handlers.c: euristics in NetFlow v9/IPFIX VLAN handler were improved for the case of flows in egress direction. Also IP protocol checks were removed for UDP/TCP ports and TCP flags in case the export protocol is NetFlow v9/IPFIX. Thanks to Alexander Ponamarchuk for his support. ! Code refactoring: improved re-usability of much of the BGP code (so to make it possible to use it as a library for some BMP daemon features, ie. Route Monitoring messages support); consolidated functions to handle log and print plugin output files; improved log messages to always include process name and type. ! fix, bpf_filter.c: issue compiling against libpcap 1.7.x; introduced a check for existing bpf_filter() in libpcap in order to prevent namespace conflicts. ! fix, tmp_net_own_field default value changed to true. This knob can be still switched to false for this release but is going to be removed soon. ! fix, cfg.c, cfg_handlers.c, pmacct.c: some configuration directives and pmacct CL parameters requiring string parsing, ie. -T -O -c, are now passed through tolower(). ! fix, MongoDB plugin: removed version check around mongo_create_index() and now defaulting to latest MongoDB C legacy driver API. This is due to some versioning issue in the driver. ! fix, timestamp_arrival: primitive was reporting incorrect results (ie. always zero) if timestamp_start or timestamp_end were not also specified as part of the same aggregation method. Many thanks to Vincent Morel for reporting the issue. ! fix, thread stack: a value of 0, default, leaves the stack size to the system default or pmacct minimum (8192000) if system default is too low. Some systems may throw an error if the defined size is not a multiple of the system page size. ! fix, nfacctd: improved NetFlow v9/IPFIX parsing. Added new length checks and fixed some existing checks. Thanks to Robert Wuttke ( @Benocs ) for his support. ! fix, pretag_handlers.c: BPAS_map_bgp_nexthop_handler() and BPAS_map_bgp_ peer_dst_as_handler() were not setting a func_type. ! fix, JSON support: Jansson 2.2 does not have json_object_update_missing() function which was introduced in 2.3. This is not provided as part of a jansson.c file and compiled in conditionally, if needed. Jansson 2.2 is still shipped along by some recent OS releases. Thanks to Vincent Bernat ( @vincentbernat ) for contributing the patch. ! fix, log.c: use a format string when calling syslog(). Passing directly a potentially uncontrolled string could crash the program if the string contains formatting parameters. Thanks to Vincent Bernat ( @vincentbernat ) for contributing the patch. ! fix, sfacctd.c: default value for config.sfacctd_counter_max_nodes was set after sf_cnt_link_misc_structs(). Thanks to Robin Douine for his support resolving the issue. ! fix, sfacctd.c: timestamp was consistently being reported as null in sFlow counters output. Thanks to Robin Douine for his support resolving the issue. ! fix, SQL plugins: $SQL_HISTORY_BASETIME environment variable was reporting a wrong value (next basetime) in the sql_trigger_exec script. Thanks to Rain Nõmm for reporting the issue. ! fix, pretag.c: in pretag_index_fill(), replaced memcpy() with hash_dup_key() also a missing res_fdata initialization in pretag_index_lookup() was solved; these issues were originating false negatives upon lookup. Thanks to Rain Nõmm fo his suppor. ! fix, ISIS daemon: hash_* functions renamed into isis_hash_* to avoid name space clashes with their BGP daemon counter-parts. ! fix, kafka_common.c: rd_kafka_conf_set_log_cb moved to p_kafka_init_host() due to crashes seen in p_kafka_connect_to_produce(). Thanks to Paul Mabey for his support resolving the issue. ! fix, bgp_lookup.c: bgp_node_match_* were not returning any match in bgp_follow_nexthop_lookup(). Thanks to Tim Jackson ( @jackson-tim ) for his support resolving the issue. ! fix, sql_common.c: crashes observed when nfacctd_stitching was set to true and nfacctd_time_new was set to false. Thanks to Jaroslav Jiráse ( @jjirasek ) for his support solving the issue. - SQL plugins: sql_recovery_logfile feature was removed from the code due to lack of support and interest. Along with it, also pmmyplay and pmpgplay tools have been removed. - pre_tag_map: removed support for mpls_pw_id due to lack of interest. ------------------------------------------------------------------- Thu Jan 14 18:59:13 UTC 2016 - mardnh@gmx.de - update to version 1.5.3 + Introduced the Kafka plugin: Apache Kafka is publish-subscribe messaging rethought as a distributed commit log. Its qualities being: fast, scalable, durable and distributed by design. pmacct Kafka plugin is designed to send aggregated network traffic data, in JSON format, through a Kafka broker to 3rd party applications. + Introduced Kafka support to BGP and BMP daemons, in both their msglog and dump flavors (ie. see [bgp|bmp]_daemon_msglog_kafka_broker_host and [bgp_table|bmp]_dump_kafka_broker_host and companion config directives). + Introduced support for a Kafka broker to be used for queueing and data exchange between Core Process and plugins. plugin_pipe_kafka directive, along with all other plugin_pipe_kafka_* directives, can be set globally or apply on a per plugin basis - similarly to what was done for RabbitMQ (ie. plugin_pipe_amqp). Support is currently restricted only to print plugin. + Added a new timestamp_arrival primitive to expose NetFlow/IPFIX records observation time (ie. arrival at the collector), in addition to flows start and end times (timestamp_start and timestamp_end respectively). + plugin_pipe_amqp: feature extended to the plugins missing it: nfprobe, sfprobe and tee. + Introduced bgp_table_dump_latest_file: defines the full pathname to pointer(s) to latest file(s). Update of the latest pointer is done evaluating files modification time. Many thanks to Juan Camilo Cardona ( @jccardonar ) for proposing the feature. + Introduced pmacctd_nonroot config directive to allow to run pmacctd from a user with non root privileges. This can be desirable on systems supporting a tool like setcap, ie. 'setcap "cap_net_raw,cap_net_admin=ep" /path/to/pmacctd', to assign specific system capabilities to unprivileged users. Patch is courtesy by Laurent Oudot ( @loudot-tehtris ). + Introduced plugin_pipe_check_core_pid: when enabled (default), validates the sender of data at the plugin side. Useful when plugin_pipe_amqp or plugin_pipe_kafka are enabled and hence a broker sits between the daemon Core Process and the Plugins. + A new debug_internal_msg config directive to specifically enable debug of internal messaging between Core process and plugins. ! bgp_table_dump_refresh_time, bmp_dump_refresh_time: max allowed value raised to 86400 from 3600. ! [n|s]facctd_as_new renamed [n|s]facctd_as; improved input checks to all *_as (ie. nfacctd_as) and *_net (ie. nfacctd_net) config directives. ! pkt_handlers.c: NF_sampling_rate_handler(), SF_sampling_rate_handler() now perform a renormalization check at last (instead of at first) so to report the case of unknown (0) sampling rate. ! plugin_pipe_amqp_routing_key: default value changed to '$core_proc_name- $plugin_name-$plugin_type'. Also, increased flexibility for customizing the key with the use of variables (values computed at startup). ! Improved amqp_receiver.py example with CL arguments and better exception handling. Also removed file amqp_receiver_trace.py, example is now merged in amqp_receiver.py. ! fix, BMP daemon: greatly improved message parsing and segment reassembly; RabbitMQ broker support found broken; several code optimizations are also included. ! fix, plugin_pipe_amqp_routing_key: check introduced to prevent multiple plugins to bind to the same RabbitMQ exchange, routing key combination. Thanks to Jerred Horsman for reporting the issue. ! fix, MongoDB plugin: added a custom oid fuzz generator to prevent concurrent inserts to fail; switched from deprecated mongo_connect() to mongo_client(); added MONGO_CONTINUE_ON_ERROR flag to mongo_insert_batch along with more verbose error reporting. Patches are all courtesy by Russell Heilling ( @xchewtoyx ). ! fix, nl.c: increments made too early after introduction of MAX_GTP_TRIALS Affected: pmacctd processing of GTP in releases 1.5.x. Patch is courtesy by TANAKA Masayuki ( @tanakamasayuki ). ! fix, pkt_handlers.c: improved case for no SAMPLER_ID, ALU & IPFIX in NF_sampling_rate_handler() on par with NF_counters_renormalize_handler(). ! fix, SQL scripts: always use "DROP TABLE IF EXISTS" for both PostgreSQL and SQLite. Pathes are courtesy by Vincent Bernat ( @vincentbernat ). ! fix, plugin_hooks.c: if p_amqp_publish_binary() calls were done while a sleeper thread was launched, a memory corruption was observed. ! fix, util.c: mkdir() calls in mkdir_multilevel() now default to mode 777 instead of 700; this allows more play with files_umask (by default 077). Thanks to Ruben Laban for reporting the issue. ! fix, BMP daemon: solved a build issue under MacOS X. Path is courtesy by Junpei YOSHINO ( @junpei-yoshino ). ! fix, util.c: self-defined Malloc() can allocate more than 4GB of memory; function is also now renamed pm_malloc(). ! fix, PostgreSQL plugin: upon purge, call sql_query() only if status of the entry is SQL_CACHE_COMMITTED. Thanks to Harry Foster ( @harryfoster ) for his support resolving the issue. ! fix, building system: link pfring before pcap to prevend failures when linking. Patch is courtesy by @matthewsf . ! fix, plugin_common.c: memory leak discovered when pending queries queue was involved (ie. cases where print_refresh_time > print_history). Thanks to Edward Henigin for reporting the issue. ------------------------------------------------------------------- Tue Sep 8 15:11:04 UTC 2015 - mardnh@gmx.de - update to version 1.5.2 - add patch: pmacct-fix-implicit-pointer-decl.diff ------------------------------------------------------------------- Sun Jul 26 07:57:48 UTC 2015 - mardnh@gmx.de - do not build with ULOG on newer versions > 13.2 since it got removed from mainstream linux kernel >= 3.17 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=7200135bc1e61f1437dc326ae2ef2f310c50b4eb ------------------------------------------------------------------- Sat Feb 21 20:28:55 UTC 2015 - mardnh@gmx.de - update to version 1.5.1 + BMP daemon: BMP, BGP Monitoring Protocol, can be used to monitor BGP sessions. The current implementation is base on the draft-ietf-grow-bmp-07 IETF draft. The daemon currently supports BMP events and stats only, ie. initiation, termination, peer up, peer down and stats reports messages. Route Monitoring is future (upcoming) work but routes can be currently sourced via the BGP daemon thread (best path only or ADD-PATH), making the two daemons complementary. The daemon enables to write BMP messages to files or AMQP queues, real-time (msglog) or at regular time intervals (dump) and is a separate thread in the NetFlow (nfacctd) or sFlow (sfacctd) collectors. + tmp_net_own_field directive is introduced to record both individual source and destination IP addresses and their IP prefix (nets) as part of the same aggregation method. While this should become default behaviour, a knob for backward-compatibility is made available for all 1.5 until the next major release. + Introduced nfacctd_stitching and equivalents (ie. sfacctd_stitching): when set to true, given an aggregation method, two new non-key fields are added to the aggregate upon purging data to the backend: timestamp_min is the timestamp of the first element contributing to a certain aggregate and timestamp_max is the timestamp of the last element. In case the export protocol provides time references, ie. NetFlow/IPFIX, these are used; if not the current time (hence time of arrival to the collector) is used instead. + Introduced amqp_routing_key_rr feature to perform round-robin load- balancing over a set of routing keys. This is in addition to existing, and more involved, functionality of tag-based load-balancing. + Introduced amqp_multi_values feature: this is same feature in concept as sql_multi_values (see docs). The value is the amount of elements to pack in each JSON array. + Introduced amqp_vhost and companion (ie. bgp_daemon_msglog_amqp_vhost) configuration directives to define the AMQP/RabbitMQ server virtual host. + BGP daemon: bgp_daemon_id now allows to define the BGP Router-ID disjoint from the bgp_daemon_ip definition. Thanks to Bela Toros for his patch. + tee plugin: introduced tee_ipprec feature to color replicated packets, both in transparent and non-transparent modes. Useful, especially when in transparent mode and replicating to hosts in different subnets, to verify which packets are coming from the replicator. + tee plugin: plugin-kernel send buffer size is now configurable via a new config directive tee_pipe_size. Improved logging of send() failures. + nfacctd: introduced support for IPFIX sampling/renormalization using element IDs: #302 (selectorId), #305 (samplingPacketInterval) and #306 (samplingPacketSpace). Many thanks to Rene Stoutjesdijk for his support. + nfacctd: added also support for VLAN ID for NetFlow v9/IPFIX via element type #243 (it was already supported via elements #58 and #59). Support was also added for 802.1p/CoS via element #244. + nfacctd: added native support for NetFlow v9/IPFIX IE #252 and #253 as part of existing primitives in_iface and out_iface (additional check). + pre_tag_map: introduced 'cvlan primitive. In NetFlow v9 and IPFIX this is compared against IE #245. The primitive also supports map indexing. + Introduced pre_tag_label_filter to filter on the 'label' primitive in a similar way how the existing pre_tag_filter feature works against the 'tag' primitive. Null label values (ie. unlabelled data) can be matched using the 'null' keyword. Negations are allowed by pre-pending a minus sign to the label value. + IMT plugin: introduced '-i' command-line option to pmacct client tool: it shows last time (in seconds) statistis were cleared via 'pmacct -e'. + print, MongoDB & AMQP plugins: sql_startup_delay feature ported to these plugins. ! sql_num_hosts: the feature has been improved to support IPv6 addresses. Pre-requisite is definition of INET6_ATON() function in the RDBMS, which is the case for MySQL >= 5.6.3. In SQLite such function has to be defined manually. ! nfacctd: improved NF_evaluate_flow_type() euristics to reckon NetFlow/ IPFIX event (NAT, Firewall, etc.) vs traffic (flows) records. ! fix, GeoIP: spit log notification (warning) in case GeoIP_open() returns null pointer. ! fix, IMT plugin: pmacct client -M and -N queries were failing to report results on exact matches. Affected: 1.5.0. Thanks to Xavier Vitard for reporting the issue. ! fix, pkt_handlers.c: missing else in NF_src_host_handler() was causing IPv6 prefix being copied instead of IPv6 address against NetFlow v9 recs containing both info. ! fix, uacctd: informational log message now shows the correct group the daemon is bound to. Thanks to Marco Marzetti for reporting the issue. ! fix, nfv9_template.c: missing byte conversion while decoding templates was causing SEGV under certain conditions. Thanks to Sergio Bellini for reporting the issue. ------------------------------------------------------------------- Thu Nov 6 21:50:04 UTC 2014 - mardnh@gmx.de - temporary workaround for misc compile issues * removed post-build-checks ------------------------------------------------------------------- Wed Sep 17 13:50:20 UTC 2014 - mardnh@gmx.de - update to version 1.5.0 - specfile cleanup ------------------------------------------------------------------- Fri Jul 30 06:09:43 UTC 2010 - pascal.bleser@opensuse.org - update to 0.12.3: * a 'cos' aggregation primitive has been implemented, providing support for 802.1p priority * TCP MD5 signatures are supported as part of the BGP daemon * in nfprobe and sfprobe, the concept of traffic direction has been introduced, and as a result [ns]fprobe_direction and [ns]fprobe_ifindex config directives have been implemented * Switch Extension Header support and Counter Samples for multiple interface features have been added in sfprobe * a number of bugfixes are included ------------------------------------------------------------------- Thu May 27 11:48:10 UTC 2010 - nix@opensuse.org - update to 0.12.2 ------------------------------------------------------------------- Wed Feb 17 00:00:00 UTC 2010 - pascal.bleser@opensuse.org - update to 0.12.0: * the "is_symmetric" aggregation primitive has been implemented and is aimed at easing detection of asymmetric traffic * tagging is now possible on BGP primitives * various fixes are also included ------------------------------------------------------------------- Mon Jul 21 00:00:00 UTC 2008 - peter+rpmspam@suntel.com.tr - Update to version 0.11.5 ------------------------------------------------------------------- Fri Nov 17 00:00:00 UTC 2006 - peter+rpmspam@suntel.com.tr - Changed the permissions of the conf files to writable ------------------------------------------------------------------- Tue May 16 00:00:00 UTC 2006 - peter+rpmspam@suntel.com.tr - Cleaned up SPEC file a some more and updated to 0.10.1 ------------------------------------------------------------------- Wed May 10 00:00:00 UTC 2006 - peter+rpmspam@suntel.com.tr - Fixup spec file to work properly on SUSE Build system ------------------------------------------------------------------- Tue Dec 27 00:00:00 UTC 2005 - silfreed@silfreed.net - upgraded to 0.9.6 - split database backends into separate binaries - added 64bit counter support by default ------------------------------------------------------------------- Thu Dec 8 00:00:00 UTC 2005 - silfreed@silfreed.net - upgraded to 0.9.5 - removed shortver ------------------------------------------------------------------- Sun Nov 13 00:00:00 UTC 2005 - silfreed@silfreed.net - upgraded to 0.9.4 ------------------------------------------------------------------- Wed Oct 12 00:00:00 UTC 2005 - silfreed@silfreed.net - upgraded to 0.9.3 ------------------------------------------------------------------- Tue Aug 23 00:00:00 UTC 2005 - silfreed@silfreed.net - upgraded to 0.9.1 ------------------------------------------------------------------- Tue May 24 00:00:00 UTC 2005 - silfreed@silfreed.net - changed 'libmysqlclient' Require to 'mysql' ------------------------------------------------------------------- Mon May 23 00:00:00 UTC 2005 - silfreed@silfreed.net - removed epoch (old versions won't upgrade correctly) - upgraded to 0.8.6 ------------------------------------------------------------------- Sat Apr 10 00:00:00 UTC 2004 - dwarner@ctinetworks.com - Initial RPM release.
