 # CBOR DNS Stream Format version 1 (CDSv1)
 This is an experimental format for representing DNS information in CBOR
 with the goals to:
 - Be able to stream the information
 - Support incomplete, broken and/or invalid DNS
 - Have close to no data quality and signature degradation
 - Support additional non-DNS meta data (such as ICMP/TCP attributes)
 ## Overview
 In CBOR you are expected to have one root element, most likely an array or
 map.  This format does not have a root element, instead you are expected to
 read one CBOR array element at a time as a stream of CBOR elements with the
 first array element being the stream initiator object.
 ```
 [stream_init]
 [message]
 ...
 [message]
 ```
 Here are some number on the compression rate compared to PCAP:
 Uncompressed | PCAP       | CDS       | Factor

 - `client` is a couple of hours of DNS from my workstation
 - `zonalizer` is half a day from [Zonalizer](https://zonalizer.makeinstall.se) which continuously tests gTLDs
 - `large ditl`, `small ditl` are capture from [DITL](https://www.dns-oarc.net/oarc/data/ditl)
 ## Types
 - `int`: A CBOR integer (major type 0x00)
 - `uint`: A CBOR integer (value >= 0, major type 0x00)
 - `nint`: A CBOR negative integer (value < 0, major type 0x00), this type has special meaning see `Negative Integers`
 - `simple`: A CBOR simple value (major type 0xe0)
 - `bytes`: A CBOR byte string (major type 0x40)
 - `string`: A CBOR UTF-8 string (major type 0x60)
 - `any`: Any CBOR value
 - `bool`: A CBOR boolean
 - `rindex`: A CBOR negative integer that is a reverse index, see `Deduplication`
 ## Special Keywords
 - `union`: Can be used to merge the given array or map into the current object
 - `optional`: The attribute or object reference is optional
 ## Negative Integers
 CBOR encodes negative numbers in a special way and this format uses that
 for none negative number to tell them apart.
 Because of that, all negative numbers needs special decoding:
 ```
 value = -value - 1
 ```
 ## Objects
 The object code below uses:
 - `[` and `]` to indicate the start and end of an array
 - `type name` per object attribute
 - `name` per object reference
 - `...` to indicate a list of previous definition
 - `(`, `|` and `)` to indicate list of various types that the attribute can be
 ### stream_init
 The initial object in the stream.
 ```
 [
    string version,
    union stream_option option,
    ...
 ]
 ```
 - `version`: The version of the format
 - `option`: A list of stream option objects
 ### stream_option

 - `RDATA_INDEX_MIN_SIZE(5) uint`: The minimum size a rdata must be to be put in the rdata index
 ## Deduplication
 Deduplication is done in a few different ways, data may be left out to
 indicate that it is the same as the previous value, an index may be used to
 indicate that it is the same as the N previous value and a reverse index
 may be used to indicate that it is the N previous value looking backwards
 across the stream.
 In other words, using the index deduplication you will need to build a table
 of the values you come across during the decoding of the stream, this table
 can grow very large.
 As an smaller alternative a reverse index can indicate often used data from
 the N previous value looking back over the stream. This type of index also
 reorder itself to try and put the most used data always in the index.

    Release 2.0.1
    Fixed incorrect line break in eventlog's (plugin) output.
    5df363c remove trailing newline
 2021-02-12 Jerry Lundström
    Release 2.0.0
    This major release contains three backward incompatible changes, two
    new command line options and a completely restructured man-page(!),
    please read the change notes carefully before upgrading!
    The first backward incompatible change has to do with the removal of
    libbind dependency. 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

    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.

    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 -?`.

    Fixes:
    - `dump_dns`: Remove usage of `strcpy()` and use `snprintf()` instead
      of `sprintf()`
    - `bpft`:

    Release 1.10.0
    This release adds a new plugin type "filter" and 5 new plugins that can
    do anonymization, deanonymization and masking of the IP addresses.
    New features:
    - Check plugins for `pluginname_type()` which returns `enum plugin_type`,
      if missing the plugin is counted as an "output" plugin
    - New plugin type "filter" which calls `pluginname_filter()` prior of
      outputting any data or calling of "output" plugins, if the new function
      returns non-zero then the packet is filtered out (dropped)
    - New extension `DNSCAP_EXT_SET_IADDR` that gives access to a function
      for setting the from and to IP addresses both in the extracted data
      and the wire
    New plugins:
    - `anonaes128`: Anonymize IP addresses using AES128
    - `anonmask`: Pseudo-anonymize IP addresses by masking them
    - `cryptopan`: Anonymize IP addresses using an extension to Crypto-PAn
      (College of Computing, Georgia Tech) made by David Stott (Lucent)
    - `cryptopant`: Anonymize IP addresses using cryptopANT, a different
      implementation of Crypto-PAn made by the ANT project at USC/ISI
    - `ipcrypt`: Anonymize IP addresses using ipcrypt create by
      Jean-Philippe Aumasson
    Bugfixes:
    - Fix changing `royparse` and `txtout` with other plugins (thanks to
      Duane Wessels and Paul Hoffman)
    - Free pointers to allocated strings in `text_free()` (thanks to Michał
      Kępień)
    - Fix IP checksum calculation
    Other changes:
    - `-B` and `-E` can be used without `-w` (thanks to Duane Wessels)
    - Use `pcap_findalldevs()` instead of `pcap_lookupdev()` (thanks to
      Michał Kępień)
    - Document and add `-?` option to all plugins
    - Fix clang `scan-build` bugs and LGTM alerts
    - Use `gmtime_r()` instead of `gmtime()`

    Release 1.9.0
    This release adds a new option to change how the Berkeley Packet Filter
    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

 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

    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

 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

 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!

    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

    - 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).

    Release 1.4.0
    Until it can be confirmed that the threaded code works as well as the
    non-threaded code it has been made optional and requires a configuration
    option to enable it during compilation.
    New extended option:
    - `-o pcap_buffer_size=<bytes>` can be used to increase the capture
      buffer within pcap-thread/libpcap, this can help mitigate dropped
      packets by the kernel during breaks (like when closing dump file).

    Release 1.3.0
    Rare lockup has been fixed that could happen if a signal was received
    in the wrong thread at the wrong time due to `pcap_thread_stop()`
    canceling and waiting on threads to join again. The handling of signals
    have been improved for threaded and non-threaded operations.
    New features:

    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.

    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:

    - 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. Also ensure
            that `capturedbytes` is zero on start.
    0077aff Correct dump trace with new `flags`
    f9cbba0 Do not use dump suffix unless it set
    4dd81d6 Update the man page
    7435c49 Change new option C to D because C was already taken
    813dddb Fix -B and -E, these options are supported only once
    76f19d1 fix usage of -W
    519b64f Add -Y option to short usage instructions
    348c738 Fix -C feature: capturedbytes was not increased
    3db6f94 Improve logging
    b567bef New option -C: limit/rotate capture after a certain amount
            of bytes
    341abdf Add -W feature: allow to specify a suffix for the pcap dump
            file, e. g.: '.pcap'
    097a3b4 Count every packet which is sent to output(), not only
            the normal ones.
    75e5968 Close PCAPs after dumper_close() to have statistics still
            available during dumper_close(). Otherwise we get a segfault
            on shutdown.

    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

    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.  It is called
            res_9_mkquery()
    5309655 Mac OS X doesn't have setresuid() and setresgid().
            This patch adds configure checks for setreuid() and setregid()
            and will use those instead if the other versions are
            not available.

 ## There are various ways to get dependency output from gcc.  Here's
 ## why we pick this rather obscure method:
 ## - Don't want to use -MD because we'd like the dependencies to end
 ##   up in a subdir.  Having to rename by hand is ugly.
 ##   (We might end up doing this anyway to support other compilers.)
 ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
 ##   -MM, not -M (despite what the docs say).  Also, it might not be
 ##   supported by the other compilers which use the 'gcc' depmode.
 ## - Using -M directly means running the compiler twice (even worse
 ##   than renaming).

 ## This next piece of magic avoids the "deleted header file" problem.
 ## The problem is that when a header file which appears in a .P file
 ## is deleted, the dependency causes make to die (because there is
 ## typically no way to rebuild the header).  We avoid this by adding
 ## dummy dependencies for each header file.  Too bad gcc doesn't do
 ## this for us directly.
 ## Some versions of gcc put a space before the ':'.  On the theory
 ## that the space means something, we add a space to the output as
 ## well.  hp depmode also adds that space, but also prefixes the VPATH
 ## to the object.  Take care to not repeat it in the output.
 ## Some versions of the HPUX 10.20 sed can't process this invocation
 ## correctly.  Breaking it into two sed invocations is a workaround.

 # serial 5 lt~obsolete.m4
 # These exist entirely to fool aclocal when bootstrapping libtool.
 #
 # In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
 # which have later been changed to m4_define as they aren't part of the
 # exported API, or moved to Autoconf or Automake where they belong.
 #
 # The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
 # in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
 # using a macro with the same name in our local m4/libtool.m4 it'll
 # pull the old libtool.m4 in (it doesn't see our shiny new m4_define
 # and doesn't know about Autoconf macros at all.)
 #
 # So we provide this file, which has a silly filename so it's always
 # included after everything else.  This provides aclocal with the
 # AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
 # because those macros already exist, or will be overwritten later.
 # We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
 #
 # Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
 # Yes, that means every name once taken will need to remain here until
 # we give up compatibility with versions before 1.7, at which point
 # we need to keep only those names which we still refer to.
 # This is to help aclocal find these macros, as it can't see m4_define.

 # Root Server Scaling Measurement (RSSM) plugin
 This plugin collects data as described by the [RSSAC002v3 specification](https://www.icann.org/en/system/files/files/rssac-002-measurements-root-06jun16-en.pdf)
 which has been created by [ICANN Root Server System Advisory Committee](https://www.icann.org/groups/rssac) (RSSAC).
 ## Additions
 As the RSSAC002v3 specification states that measurements should be saved per
 24 hours interval, this plugin produces additional metrics that can be used
 to compile the 24 hours measurements allowing for variable time between
 output generation.
 Metric `dnscap-rssm-sources` has a hash entry called `sources` which lists
 IP addresses and the number of times they appeared.
 Metric `dnscap-rssm-aggregated-sources` has a hash entry called `aggregated-sources`
 which lists the aggregated IPv6 addresses by a /64 net and the number of times
 it has appeared.
 ## Merge Tool
 The Perl script `dnscap-rssm-rssac002` is included and installed with `dnscap`
 and can be used to multiple combine RSSM plugin RSSAC002v3 YAML output files
 into one file.
 The script will merge and remove metric specific to this plugin and replace
 others to fill in correct values for the new time period. The earliest
 `start-period` found will be used for all metrics.
 **NOTE** no parsing of `start-period` is performed, it is up to the operator
 to only give input files related to the same 24 hour period.
 Options:
 - `--no-recompile`: Disabled the combining of metrics and the removal of
  metrics specific to this plugin
 - `--keep-dnscap-rssm`: Do the combining but keep the metrics specific to
  this plugin
 - `--sort`: Output will always start with `version:`, `service:`,
  `start-period:` and `metric:`, rest of the values are not ordered by label.
  This option enabled sorting of them, which is not required by the
  specification but may help in debugging and testing cases.

 dnscap is a network capture utility designed specifically for DNS
 traffic. It produces binary data in pcap(3) format. This utility
 is similar to tcpdump(1), but has a number of features tailored
 to DNS transactions and protocol options.

 * Thu Mar 11 2021 Jerry Lundström <lundstrom.jerry@gmail.com> 2.0.1-1
 - Release 2.0.1
  * Fixed incorrect line break in eventlog's (plugin) output.
  * Commits:
    5df363c remove trailing newline
 * Fri Feb 12 2021 Jerry Lundström <lundstrom.jerry@gmail.com> 2.0.0-1
 - Release 2.0.0
  * This major release contains three backward incompatible changes, two
    new command line options and a completely restructured man-page(!),
    please read the change notes carefully before upgrading!
  * The first backward incompatible change has to do with the removal of
    libbind dependency. 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

 * Thu Oct 22 2020 Jerry Lundström <lundstrom.jerry@gmail.com> 1.12.0-1
 - 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.

 * Thu Aug 20 2020 Jerry Lundström <lundstrom.jerry@gmail.com> 1.11.1-1
 - 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 -?`.

 * Mon Dec 03 2018 Jerry Lundström <lundstrom.jerry@gmail.com> 1.10.0-1
 - Release 1.10.0
  * This release adds a new plugin type "filter" and 5 new plugins that can
    do anonymization, deanonymization and masking of the IP addresses.
  * New features:
    - Check plugins for `pluginname_type()` which returns `enum plugin_type`,
      if missing the plugin is counted as an "output" plugin
    - New plugin type "filter" which calls `pluginname_filter()` prior of
      outputting any data or calling of "output" plugins, if the new function
      returns non-zero then the packet is filtered out (dropped)
    - New extension `DNSCAP_EXT_SET_IADDR` that gives access to a function
      for setting the from and to IP addresses both in the extracted data
      and the wire
  * New plugins:
    - `anonaes128`: Anonymize IP addresses using AES128
    - `anonmask`: Pseudo-anonymize IP addresses by masking them
    - `cryptopan`: Anonymize IP addresses using an extension to Crypto-PAn
      (College of Computing, Georgia Tech) made by David Stott (Lucent)
    - `cryptopant`: Anonymize IP addresses using cryptopANT, a different
      implementation of Crypto-PAn made by the ANT project at USC/ISI
    - `ipcrypt`: Anonymize IP addresses using ipcrypt create by
      Jean-Philippe Aumasson
  * Bugfixes:
    - Fix changing `royparse` and `txtout` with other plugins (thanks to
      Duane Wessels and Paul Hoffman)
    - Free pointers to allocated strings in `text_free()` (thanks to Michał
      Kępień)
    - Fix IP checksum calculation
  * Other changes:
    - `-B` and `-E` can be used without `-w` (thanks to Duane Wessels)
    - Use `pcap_findalldevs()` instead of `pcap_lookupdev()` (thanks to
      Michał Kępień)
    - Document and add `-?` option to all plugins
    - Fix clang `scan-build` bugs and LGTM alerts
    - Use `gmtime_r()` instead of `gmtime()`
    - Update `pcap-thread` to v4.0.0

 * Wed Feb 28 2018 Jerry Lundström <lundstrom.jerry@gmail.com> 1.9.0-1
 - Release 1.9.0
  * This release adds a new option to change how the Berkeley Packet Filter
    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
  * Commits:
    47d892b Issue #152: RSSM YAML output
    d4f1466 Issue #152, Issue #91: Parse DNS before processing RSSM counters
    68fc1ff BPF, `bpf_hosts_apply_all`
 * Wed Feb 07 2018 Jerry Lundström <lundstrom.jerry@gmail.com> 1.8.0-1
 - 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

 * Wed Dec 27 2017 Jerry Lundström <lundstrom.jerry@gmail.com> 1.7.1-1
 - 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

            actual size and reparse
    99bda0b Fix #98: VLAN
 * Tue Dec 19 2017 Jerry Lundström <lundstrom.jerry@gmail.com> 1.7.0-1
 - 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

            that don't actually perform DNSSEC validation.
 * Fri Dec 01 2017 Jerry Lundström <lundstrom.jerry@gmail.com> 1.6.0-1
 - 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!

 * Tue Jun 06 2017 Jerry Lundström <lundstrom.jerry@gmail.com> 1.5.0-1
 - 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):

    - 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. First there will be some
      test queries to ensure the zone is reachable and configured to receive
      data. Then a query naming the fields, followed by the periodic queries
      delivering counts.
    - fd23be7: Make report zone, server, node command line argumements mandatory
    - 137789b: Adding rzkeychange plugin files
 * Wed Mar 29 2017 Jerry Lundström <lundstrom.jerry@gmail.com> 1.4.1-1
 - Release 1.4.1
  * Fixed an issue that when compiled with libpcap that had a specific
    feature enabled it would result in a runtime error which could not be
    worked around.
  * Also fixed various compatibility issues and updated dependency
    documentation for CentOS.

    c6fdb7a Fix typo and remove unused variables
 * Mon Feb 27 2017 Jerry Lundström <lundstrom.jerry@gmail.com> 1.4.0-1
 - Release 1.4.0
  * Until it can be confirmed that the threaded code works as well as the
    non-threaded code it has been made optional and requires a configuration
    option to enable it during compilation.
  * New extended option:
    - `-o pcap_buffer_size=<bytes>` can be used to increase the capture
      buffer within pcap-thread/libpcap, this can help mitigate dropped
      packets by the kernel during breaks (like when closing dump file).
  * Commits:
    1c6fbb2 Update copyright year
    63ef665 Suppress OpenBSD warnings about symbols
    2c99946 pcap-thread v2.0.0, disable threads, errors handling

 * Fri Dec 23 2016 Jerry Lundström <lundstrom.jerry@gmail.com> 1.3.0-1
 - Release 1.3.0
  * Rare lockup has been fixed that could happen if a signal was received
    in the wrong thread at the wrong time due to `pcap_thread_stop()`
    canceling and waiting on threads to join again. 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

 On Linux systems, the default might be to monitor all interfaces but most
 commonly it will also capture on the first interface.
 This depends on the libpcap version.
 If you want to make sure you're capturing on all interfaces then use the
 special "any" or "all" (depends on system).
