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 + + Release 1.11.0 + + This release includes a new plugin called `eventlog`, contributed + by Byron Darrah (@ByronDarrah), output DNS activity as log events, + including answers to A and AAAA queries. + + Other changes includes compile warning and code analysis fixes. + + 382eac4 COPR + 4c03650 Compile warn + 21d6a67 Slight change -- wording now matches usage() output. + dd19b0b Added the eventlog.so plugin... + 1ebf504 Added new dnscap plugin: evenlog.so... + f3f9aaa Compile warnings + +2020-03-02 Jerry Lundström + + Release 1.10.4 + + Fixed a bug that would not drop privileges when not specifying any + interface (which is equal to capturing on all interfaces). + Added functionality to set the supplemental groups when dropping + privileges and changing user, or clear them if that is not supported. + Other changes includes corrected man-page about '-w' and update to + documentation. + + a0285e4 drop privileges errors, initgroups/setgroups + 96336f3 daemon: Attempt to drop supplemental groups + 467a9a7 Drop privileges + de940a8 man-page -w + 187ec43 README + +2019-10-02 Jerry Lundström + + Release 1.10.3 + + Fixed plugins inclusion in deb packages for Debian and Ubuntu. + + 017ebb2 Deb packages + cf59143 COPR, spec + +2019-08-05 Jerry Lundström + + Release 1.10.2 + + Fixed bug in the handling of defragmentation configuration which lead + to the use of a local scope variable later on and caused unexpected + behavior. + + 91692b8 Frag conf + 6a74376 Package + d0d1a6d Package + +2019-07-08 Jerry Lundström + + Release 1.10.1 + + Fix various issues found by code analysis tools, a few compiler warnings + removed, undefined bit shift behavior fixed, parameter memory leaks + plugged and documentation updates. + + Fixes: + -

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).
