This library was causing segfaults on OpenBSD due to - shared (and overwritten) symbols with OpenBSD's libc. - It was replaced with LDNS and LDNS renders domain names as Fully - Qualified Domain Names (FQDN, the trailing dot!) so every output of a - domain name has been changed to a FQDN. - This also changes `-X`/`-x`, which will now match against FQDNs. - - The second backward incompatible change is that `-6` has been removed. - This was used to alter the BPF in order to "fix" it, dnscap adds - specific filters to IP and UDP headers which does not work for IPv6 - traffic. - The generated BPF has been changed to allow IPv6 to always pass, making - the option obsolete. IPv6 filtering is then done in dnscap. - - The last backward incompatible change has to do with the output format - of `-g` related to EDNS0 and is now more consistent with the rest of - the parsable output: - - No more spaces in the output - - Fix incorrect `\` and extra empty new-line - - All EDNS0 options are added after `edns0[...]` using comma separation, example: `edns0[],edns0opt[],...` - - Client Subnet format: `edns0opt[ECS,family=nn,source=nn,scope=nn,addr=...]` - - Unknown/unsupported code: `edns0opt[code=nn,codelen=nn]` - - Parsing error messages have changed, they came from libbind, now comes from LDNS - - New options: - - Add `-q` and `-Q` to filter on matched/not matched QTYPE - - Bugfixes: - - Fix memory leak in EDNS0 ECS address parsing - - `network`: Fix sonarcloud issues, potential `memcpy()` of null pointer - - Other changes: - - Fix CBOR output inclusion, LDNS is always available now - - Add macros for Apple and Windows endian functions - - Restructure and correct the man-page - - 557e5f5 man-page - 025529f v6bug, interval - 37b79e9 FQDN - ebcf434 QTYPE match, args, tests - 0cb5562 v6bug - 75f6115 Endian - aaeb213 Sonarcloud - 8685946 CBOR output - 3e26802 Sonarcloud - 30aa366 libbind - 3f94d0b Mattermost - -2020-10-22 Jerry Lundström - - Release 1.12.0 - - This release fixes the handling of `-?` option for dnscap and all plugins, - previously the handling varied between places and depending on `getopt()` - implementation an invalid option could return the wrong exit code. - - Other changes: - - Fix typo in configure help text - - `plugins/anonmask`: Fix typo in help text - - `plugins/rzkeychange`: - - Add `-D`, dry run mode, for testing - - Fix handling of `-a` and error on too many - - KNOWN ISSUES: - - On OpenBSD the system library libc exports the same symbols as libbind - does and this causes runtime warnings. Until now this has not caused any - known problems but is now also causing segfaults if the packet filter used - (BPF) includes IPv6 addresses. - On all other platforms OARC supports, these symbols are macros and in so - should not cause any problem. - - ee478c0 Known issues - 2f9d957 Tests - 3c663a2 Tests - c88efc5 rzkeychange test - f062f33 Tests - -2020-08-20 Jerry Lundström - - Release 1.11.1 - - This release fixes a lot of issues found by code analysis, adds a - explicit memory zeroing function to remove account information (read - when dropping privileges) and adds code coverage reporting. - - The `dnscap_memzero()` will use `explicit_bzero()` on FreeBSD and - OpenBSD, or `memset_s()` (if supported), otherwise it will manually - set the memory to zero. This will hopefully ensure that the memory - is zeroed as compilers can optimize out `memset()`'s that is just - before `free()`. - - The plugins exit code for the help option `-?` has been changed to 0 - to have the same as `dnscap -?`. - - d9747ee memzero - 1cf17c6 Coverage - 19c7120 Coverage - 7435676 Sonarcloud - 928e181 Sonarcloud - ca4afd0 Sonarcloud - 028f5e0 Badges - db0d6a1 LGTM - -2020-06-01 Jerry Lundström -

is generated to include the host restrictions for all selections, - previously this restriction would only apply to specific parts. - - Additional tweaks to the RSSM plugin has been made to conform to the - RSSAC002v3 specification. One noticeable change is that the plugin now - requires the DNS to be parsed before counted, any error in the parsing - will result in the message being left out of the statistics. - - Changes: - - Fix spacing in BPF filter to look better - - Fix #146: Add `bpf_hosts_apply_all`, apply any host restriction to all - - `plugin/rssm`: - - Remove quoting of `start-period` and correctly handle empty hashes - - Issue #152, Issue #91: Parse DNS before processing RSSM counters - - `plugin/rssm/dnscap-rssm-rssac002`: Use `YAML::Dump()` for output - - 47d892b Issue #152: RSSM YAML output - d4f1466 Issue #152, Issue #91: Parse DNS before processing RSSM counters - 68fc1ff BPF, `bpf_hosts_apply_all` - -2018-02-07 Jerry Lundström - - Release 1.8.0 - - This release updates the TCP stream code in order to be able to look - at more then just the first query, for handling already ongoing TCP - connections without having seen SYN/ACK and for reassembly of the TCP - stream prior of parsing it for DNS with an additional layer of parsing - (see `reassemble_tcp_bfbparsedns`). - - Updates to the Root Server Scaling Measurement (RSSM) plugin have also - been made to bring it up to date with RSSAC002v3 specification, be - able to output the YAML format described and an additional script to - merge YAML files if the interval is less then the RSSAC002v3 24 hour - period. See "Updates to the RSSM plugin" below and - `plugins/rssm/README.md`. - - New extended options: - - `parse_ongoing_tcp`: Start tracking TCP connections even if SYN/ACK - has not been seen - - `allow_reset_tcpstate`: Allow external reset of TCP state - - `reassemble_tcp`: Use to enable TCP stream reassembly - - `reassemble_tcp_faultreset`: Number of faults before reseting TCP - state when reassembly is enabled - - `reassemble_tcp_bfbparsedns`: Enable an experimental additional layer - of reassemble that uses `libbind` to parse the payload before accepting - it. If the DNS is invalid it will move 2 bytes within the payload and - treat it as a new payload, taking the DNS length again and restart - the process. Requires `libbind` and `reassemble_tcp`. - - New extension functions for plugins: - - `DNSCAP_EXT_TCPSTATE_GETCURR`: Function to get a pointer for the - current TCP state - - `DNSCAP_EXT_TCPSTATE_RESET`: Function to reset a TCP state - - New features: - - Parse additional DNS queries in TCP connections - - `-g` and the `txtout` plugin will reset TCP state (if allowed) on - failure to parse DNS - - Bugfixes: - - Fix `-g` output, separate error message with a space - - Fix TCP packets wrongfully flagged as DNS when using layers. - - Fix TCP debug output when using layers, `ia_str()` is not safe to call - twice in the same `printf` because of local buffer. - - Fix exported extension functions, need to be file local - - New tests for: - - Multiple DNS queries in one TCP connection - - Query over TCP without SYN - - Queries over TCP with first query missing length - - Queries over TCP with middle payloads missing - - Add test with TCP stream that missing multiple packets in the middle - - Updates to the RSSM plugin (`plugins/rssm`): - - Add info about saving counts and sources - - Fix memory leak on `fopen()` errors - - Update to RSSAC002v3 specification - - New options: - - `-D` to disable forking on close - - `-Y`: Use RSSAC002v3 YAML format when writing counters, the file - will contain multiple YAML documents, one for each RSSAC002v3 metric - Used with; -S adds custom metric `dnscap-rssm-sources` and -A adds - `dnscap-rssm-aggregated-sources` - - `-n`: Set the service name to use in RSSAC002v3 YAML - - `-S`: Write source IPs into counters file with the prefix `source` - - `-A`: Write aggregated IPv6(/64) sources into counters file with - the prefix `aggregated-source` - - `-a`: Write aggregated IPv6(/64) sources to - `<name>.<timesec>.<timeusec>` - - Add `dnscap-rssm-rssac002` Perl script for merging RSSAC002v3 YAML files - - Add README.md for the plugin man-page for `dnscap-rssm-rssac002` - - Add test for YAML output and merging of YAML files - - c7058c8 Use file local functions for all extensions - 66b352d RSSM RSSAC002v3 YAML Tool - b09efc2 `plugins/rssm` RSSAC002v3 - 709aba6 Fix #89: Add additional reassembly layers that parses the - payload byte for byte for valid DNS - 04fa013 Fix CID 1463944 (again) - b1cf623 RSSM saving data and forking - fb23305 Fix CID 1463944 - 0fca1a8 Issue #89: TCP stream reassemble - bb6428c CID 1463814: Check `ns_initparse()` for errors - a57066f Fix #88: TCP handling - -2017-12-27 Jerry Lundström - - Release 1.7.1 - - The library used for parsing DNS (libbind) is unable to parse DNS - messages when there is padding at the end (the UDP/TCP payload is larger - then the DNS message). This has been fixed by trying to find the actual - DNS message size, walking all labels and RR data, and then retry parsing. - - Other changes and bug-fixes: - - Fix size when there is a VLAN to match output of `use_layers` yes/no - - Add test of VLAN matching - - Fix `hashtbl.c` building in `rssm` - - Add test with padded DNS message - - 49e5400 Fix #127: If `ns_initparse()` returns `EMSGSIZE`, try and get - actual size and reparse - 99bda0b Fix #98: VLAN - -2017-12-19 Jerry Lundström - - Release 1.7.0 - - This release adds IP fragmentation handling by using layers in pcap-thread - which also adds a new flag to output and modules. `DNSCAP_OUTPUT_ISLAYER` - indicates that `pkt_copy` is equal to `payload` since the layers of the - traffic have already been parsed. IP fragments are reassembled with the - `pcap_thread_ext_frag` extension that is included in pcap-thread. - - New extended (`-o`) options: - - `use_layers`: Use pcap-thread layers to handle the traffic - - `defrag_ipv4`: Enabled IPv4 de-fragmentation - - `defrag_ipv6`: Enabled IPv6 de-fragmentation - - `max_ipv4_fragments`: Set maximum fragmented IPv4 packets to track - - `max_ipv4_fragments_per_packet`: Set the maximum IPv4 fragments per - tracked packet - - `max_ipv6_fragments`: Set maximum fragmented IPv6 packets to track - - `max_ipv6_fragments_per_packet`: Set the maximum IPv6 fragments per - tracked packet - - Currently `-w` does not work with `use_layers` and the plugins `pcapdump` - and `royparse` will discard output with the flag `DNSCAP_OUTPUT_ISLAYER` - because they need access to the original packet. - - The `rzkeychange` plugin now encodes certain flag bits in the data that - it reports for RFC8145 key tag signaling. The flags of interest are: - `DO`, `CD`, and `RD`. These are encoded in an bit-mask as a hexadecimal - value before the `_ta` component of the query name. - - Other changes and bug-fixes: - - Fix #115: document `-g` output, see `OUTPUT FORMATS` `diagnostic` in - `dnscap(1)` man-page - - Add test to match output from non-layers runs with those using layers - - Add test with fragmented DNS queries - - Fix #120: CBOR/CDS compiles again, update tinycbor to v0.4.2 - - Fix `ip->ip_len` byte order - - Fix parsing of IP packets with padding or missing parts of payload - - 0347f74 Add AUTHORS section in man-page - ef1b68c Fix CID 1463073 - 8a79f89 Layers - a404d08 Update pcap-thread to v3.1.0, add test for padding fixes - 08402f1 Fix byte order bug. ip->ip_len must be evaluated with ntohs(). - d6d2340 CBOR/CDS and formatting - 85ec2d8 Fix #87: IP fragmentation reassembly - 22bfd4a Documentation - c35f19f Adding flag bits to rzkeychange RFC8145 key tag signaling data. - This may be useful to find "false" key tag signals from sources - that don't actually perform DNSSEC validation. - -2017-12-01 Jerry Lundström - - Release 1.6.0 - - New additions to the plugins: - - `rzkeychange` can now collect RFC8145 key tag signaling. Signals are - saved during the collection interval, and then sent to the specified - `-k <zone>`, one at a time, at the end of the interval. Only root zone - signals are collected. Added by Duane Wessels (@wessels). - - `royparse` is a new plugin to splits a PCAP into two streams, queries - in PCAP format and responses in ASCII format. Created by Roy Arends - (@RoyArends). - - `txtout` new option `-s` for short output, only print QTYPE and QNAME - for IN records. Added by Paul Hoffman (@paulehoffman) - - The extension interface has been extended with `DNSCAP_EXT_IA_STR` to - export the `ia_str()` function. - - Bugfixes and other changes: - - Remove duplicated hashtbl code - - `rssm`: fix bug where count in table was taken out as `uint16_t` but - was a `uint64_t` - - Handle return values from hashtbl functions - - `txtout`: removed unused `-f` options - - Change `ia_str()` to use buffers with correct sizes, thanks to - @RoyArends for spotting this! - - Commits: - 3f78a31 Add copy/author text - 1bd914d Fix CID 1462343, 1462344, 1462345 - f9bb955 Fix `fprintf()` format for message size - abedf84 Fix #105: `inet_ntop` buffers - bfdcd0d Addresses the suggestions from Jerry. - dda0996 royparse :) - 4f6520a royparse plugin finished - f1aa4f2 Fix #103: Remove `opt_f` - 32355b7 Rearrange code to keep the change smaller and fix indentation - d6612c1 Added -s to txtout for short output - 9d8d1ef Check return of `snprintf()` - 55f5aba Format code - 9f19ec3 Fixed memory leak in rzkeychange_keytagsignal() - 58b8784 Fix memory leaks and better return value checks in - rzkeychange_submit_counts() - b06659f Add server and node to keytag signal query name - 705a866 Always free response packets in rzkeychange plugin. - e802843 Implement RFC8145 key tag signal collection in rzkeychange plugin - 5fbf6d0 Added extension for ia_str() so it can be used by rzkeychange - plugin. - 3be8b8f Split `dnscap.c` into more files - e431d14 Fix #92: hashtbl - -2017-08-21 Jerry Lundström - - Release 1.5.1 - - Compatibility fixes for FreeBSD 11.1+ which is now packing `struct ip` - and for OpenBSD. - - Commits: - 17e3c92 FreeBSD is packing `struct ip`, need to `memcpy()` - f8add66 Code formatting - 38cd585 Add documentation about libbind - d1dd55b Fix #82: Update dependencies for OpenBSD - -2017-06-06 Jerry Lundström - - Release 1.5.0 - - Added support for writing gzipped PCAP if the `-W` suffix ends with - `.gz` and made `-X` work without `-x`. New inteface for plugins to - tell them what extensions are available and a new plugin `rzkeychange`. - - Plugin extensions: - - Call `plugin_extension(ext, arg)` to tell plugin what extensions exists - - Add extension for checking responder (`is_responder()`) - - The rzkeychange plugin was developed by Duane Wessels 2016 in support - of the root zone ZSK size increase. It is also being used in support of - the 2017 root KSK rollover and collects the following measurements: - - total number of responses sent - - number of responses with TC bit set - - number of responses over TCP - - number of DNSKEY responses - - number of ICMP_UNREACH_NEEDFRAG messages received - - number of ICMP_TIMXCEED_INTRANS messages received - - number of ICMP_TIMXCEED_REASS messages received - - Other fixes (author Duane Wessels): - - 232cbd0: Correct comment description for meaning of IPPROTO_AH - - 181eaa4: Add #include <sys/time.h> for struct timeval on NetBSD - - Commits: - - 1d894e2 Make -x and -X work correctly together and update man-page - 34bc54c Make the -X option work without requiring a -x option. - f43222e Fix CID 1440488, 1440489, 1440490 - aa54395 Update pcap-thread to v2.1.3 - 81174ce Prepare SPEC for OSB/COPR - 21d7468 New plugin rzkeychange and plugin extensions - 38491a3 Config header is generated by autotools - 419a8ab Small tweaks and fixes for gzip support - 1967abc updated for earlier BSD versions - f135c90 added auto gzip if the -W suffix ends with .gz - - Commits during development of rzkeychange (author Duane Wessels): - - 620828d: Add rzkeychange -z option to specify resolver IP addresses - - 1f77987: Add -p and -t options to rzkeychange plugin to configure an - alternate port and TCP. Useful for ssh tunnels. - - 2a571f1: Split ICMP time exceeded counter into two counters for time - exceeded due to TTL and another due to fragmentation - - e4ee2d3: The rzkeychange data collection plugin uses - `DNSCAP_EXT_IS_RESPONDER` extension to know if an IP address is a - "responder" or not, because when dnscap is instructed to collect ICMP - with -I, it processes all ICMP packets, not just those limited to - responders (or initiators). - - cee16b8: Add ICMP Time Exceeded to counters - - ad8a227: Counting source IPs has performance impacts. #ifdef'd out for - now add ICMP "frag needed" counts - - c25e72b: Implemented DNS queries with ldns.

The handling of signals - have been improved for threaded and non-threaded operations. - - New features: - - Experimental CBOR DNS Stream format output, see `CBOR_DNS_STREAM.md` - - Extended options to specify user and group to use when dropping - privileges, see EXTENDED OPTIONS in man-page - - Commits: - - a5fa14e Signal and threads - 3868104 Use old style C comments - 7946be5 Clarify building - d5463b4 RPM spec and various automake fixes - df206bf Resource data indexing and documentation - 0e2d0fe Fix #22, fix #43: Update README - 5921d73 Add stream option RLABELS and RLABEL_MIN_SIZE - 6dd6ec1 Implement experimental CBOR DNS Stream Format - 4baf695 Fix #37: Extended options to specifty user/group to use when - dropping privileges - 61d830a Fix #35: Use `AC_HEADER_TIME` and fix warning - -2016-10-27 Jerry Lundström - - Release 1.2.0 - - Update `pcap-thread` to v1.2.0 to get the new callback queue mode which - puts that mode into using pthread conditions if all pcaps are offline and - keeps us from losing packets. - - Use `pcap_thread_dropback()` callback to get the notification when a - packet was dropped because the queue was full, indicating that we can't - process all the packets. Added this stats to the `-S` output as total - and per interface as `ptdrop`. Changed the output for each interface - to not cut of information, for example interface name was cut to - 4 characters. - - Other changes: - - - Add extended options `-o <option>=<value>` because we are running out - of short options. - - Better handling of library checks and automake rules - - New option `-F <format>` to specify the format of the output in `-w` - - Add experimental CBOR output support - - LDNS is used to parse the packets - - Tinycbor is used to construct the CBOR output - - DNS-in-JSON draft [1] for representing the objects - - Check CBOR topic in README.md for more information - - When only reading offline pcap files it will not attempt to drop - privileges and add new option `-N` to explicitly not drop privileges. - - Commits: - - f42e23f Extended options and CBOR output format - a28f498 Fix #24: Handle packet drops - 2308eaa Fix #26: Unable to drop GID to nobody, exiting. - 82d65f2 Update pcap-thread to v1.1.2 - - [1] https://datatracker.ietf.org/doc/draft-hoffman-dns-in-json/ - -2016-10-11 Jerry Lundström - - Release 1.1.0 - - The ownership of DNSCAP was transferred from ISC to DNS-OARC in - the summer of 2016 and this is the first release since that. - - This project now uses Semantic Versioning and these are the changes - since the `dnscap-20160205` release (which can also be found using - the tag `v0.0.0-20160205`). - - Highlights: - - Restructure repository and use autotools - - Compiled and tested on Debian, Ubuntu, CentOS, FreeBSD and OpenBSD - using Jenkins and Travis-CI - - Source code static analysis using Coverity Scan - - Compatibility fixes for FreeBSD, OpenBSD and OS X - - ABI change to `output()`, previous `isfrag` is now a `flags` that - represents what the packet is through a bitmask - - Use helper library `pcap-thread` when capturing to solve missing - packets during very low traffic - - New command line options: - - `-V`: Prints version and then exits - - `-M`: Enable monitor mode on interfaces - - `-D`: Enable immediate mode on interfaces - - `-W`: Allow to specify a suffix for the pcap dump file - - `-C`: Limit/rotate capture after a certain amount of bytes - - Special thanks to: - - Duane Wessels - - Paul Vixie - - Klaus Darilion - - Commits: - - bc7eb22 Update license after ownership transfer from ISC to DNS-OARC, - update contributors, add build badges and removed SuperFastHash - since apparently it was not used. - 778e457 Add `-V` for displaying version and the exiting - 71c2d79 Fix #12: Sync man-page and help text - 33576ef Swap option C and D, C for this makes more sense.

For now pass pkt=NULL to be safe for plugins. - ea8f9a4 Make the family of output() functions future proof with a flags - bitmask. Rather than separate 'isfrag' and 'isdns' flags, - they are now set as bitmasks in a single 'flags' value passed - to output() f - 472a172 A change to the interface of the family of output() functions. - 95a6e62 timeval.* are not unsigned - d3f32de Fix #1: Use NS_*SZ - e555871 Fix compiler warnings - 3ed8f29 Fix #1 - 864cbd7 Can you change #ifdef __APPLE__ to check for the - arpa/nameser_compat.h header and include it if it exists? - 796e8ea plugin/rssm needs to include arpa/nameser_compat.h for OS X - so that the HEADER struct is declared. - daf4bd3 In plugin/txtout silence compiler warnings about int vs short - e5bc24b plugin/pcapdump needs to include arpa/nameser_compat.h for OS X - so that the HEADER struct is declared. - 0061b57 Work around configure problem detecting libresolv on Mac OS X - Without some #include files, the configure test won't find - the symbol res_mkquery() in libresolv on OS X.
