12 Updated Yggdrasil library, with several other ones.
17 @section Release 8.8.1
21 Fixed @command{nncp-daemon} failing with unauthenticated connection and
22 enabled @option{-autotoss}.
30 @section Release 8.8.0
34 Fixed buildability under Go 1.19.
37 Minimal required Go version is 1.17.
45 @section Release 8.7.2
49 More intuitive, clear and slightly more flexible behaviour of @command{nncp-rm}.
52 @command{nncp-rm} also removes corresponding @file{hdr/} file for each
58 @section Release 8.7.1
62 @command{nncp-xfer} now correctly checks for @file{seen/} files for
68 @section Release 8.7.0
72 @command{nncp-ack} does not acknowledge ACK-packets, preventing an
76 @command{nncp-ack} previously did not remove corresponding @file{hdr/} files.
79 @command{nncp-rm} now takes list of packet from @code{stdin} when
80 @option{-pkt} option is used.
83 @command{nncp-ack} now generates list of ACK packets it created, that
84 could be used as an input to @command{nncp-rm} to remove outbound ACK
90 @section Release 8.6.0
94 @command{nncp-xfer} checks if locally copied packet's checksum differs
95 from the source's one.
98 @command{nncp-call} has bad return code if its queues contain unfinished jobs.
101 @command{nncp-ack} command appeared, that sends explicit packet receipt
102 acknowledgement (ACK packet). That acknowledgement deletes referenced
103 packet from the outbound spool.
106 Ability to turn @code{fsync} operation off using @env{$NNCPNOSYNC=1}
107 environment variable.
110 Added various indices in documentation, that should help searching in it.
115 @section Release 8.5.0
119 Fixed @command{nncp-bundle} workability.
122 Mistakenly @option{-mcd-wait} option was enabled by default in
126 Ability to override internal default timeout for online protocol through
127 @env{$NNCPDEADLINE} environment variable. Can be useful for very high
131 NNCP builds on OpenBSD.
136 @section Release 8.4.0
140 Multicast related interface names (@code{mcd-listen} and @code{mcd-send}
141 configuration options) are now regular expressions. By default
142 @command{nncp-cfgnew} uncomments them now with @code{.*} interface name.
145 @command{nncp-call} command has @option{-mcd-wait} option to wait for
146 multicast packet about node's address.
149 @command{nncp-file} command skips everything that is neither regular
150 file nor directory during pax-archive creation.
155 @section Release 8.3.0
159 Fixed building issues on 32-bit systems.
164 @section Release 8.2.0
168 Yggdrasil uses pure-Go IPv6+TCP network stack, instead of naked μTP
169 transport protocol, making it able to work as an ordinary TCP server
170 inside overlay network.
173 Yggdrasil's @code{prv;bind1,bind2;pub@dots{}}-like configuration strings are
174 replaced with URL-like ones (@code{yggdrasils://PRV?bind=BIND1&bind=BIND2&pub=PUB}).
177 Ability to pass multicast-related parameters to Yggdrasil configuration.
180 @command{nncp-daemon} is able to listen on both TCP and Yggdrasil-driven
181 sockets simultaneously.
184 @command{nncp-daemon}'s listening on peering endpoint socket is optional
185 -- you can be reached through the peers.
190 @section Release 8.1.0
194 @command{nncp-cfgdir} does not require @code{self} section existence in
198 Ability to act as Yggdrasil network client, using online protocol on top of it.
203 @section Release 8.0.2
207 Fixed sending ability to areas.
212 @section Release 8.0.1
216 Fixed incorrect @code{freq.chunked} value calculation. If it was missed,
217 then chunked transfer mode was forcefully turned on anyway.
220 Fixed incorrect full file's size calculation in @file{.nncp.meta}.
225 @section Release 8.0.0
229 @strong{Incompatible} encrypted packet format change: payload and pad
230 sizes are sent in-bound in the encrypted stream. That gives ability to
231 streamingly create encrypted packets, without knowing sizes in advance,
232 without creating temporary file or buffer data in memory.
235 Proper encrypted packet padding verification is done now. This is not
236 critical issue, but previously neither padding value, nor its size were
237 authenticated, giving ability to iteratively strip trailing bytes and
238 determine payload's size by observing the reaction of the encrypted
242 @command{nncp-exec} loses its @option{-use-tmp} option, because of
243 streaming-compatible encrypted packets format.
246 @command{nncp-file} and @command{nncp-exec} commands have
247 @option{-maxsize} option, limiting maximal resulting encrypted packet's
248 maximal size (returning error if it is exceeded). Could be useful,
249 because no payload size could be known in advance.
254 @section Release 7.7.0
258 Experimental @code{kqueue} and @code{inotify} based notifications
259 support about spool directory changes, for reducing their often reading
263 @file{.seen} and @file{.hdr} files moved to @file{seen/} and @file{hdr/}
264 subdirectories, for faster scanning of spool directories.
265 Current files migration required:
268 $ find $NNCPSPOOL -type f -name "*.hdr" -exec rm @{@} +
270 $ find $NNCPSPOOL -type d -name rx | while read rx ; do
273 find . -type f -name "*.seen" | while read fn ; do
274 mv $fn seen/$@{fn%.seen@}
278 $ find $NNCPSPOOL -type d -name area | while read area ; do
279 find $area -type f -name "*.seen" | while read fn ; do
288 @section Release 7.6.0
292 Logging may be done to specified opened file descriptor
293 (@env{$NNCPLOG=FD:5} for example).
294 That is friendly to use under @command{daemontools}.
297 Added additional checks of public keys existence in configuration file,
298 preventing some commands from failing.
303 @section Release 7.5.1
307 NNCP builds on NetBSD.
312 @section Release 7.5.0
316 @command{nncp-daemon} is compatible with UCSPI-TCP interface, so log
317 will contain remote side's address (when running under appropriate
318 utility). @option{-ucspi} option should be used instead of @option{-inetd}.
321 @command{nncp-call} can be UCSPI-TCP client, using @option{-ucspi} option.
324 Do not exit if some of MCD network interfaces can not be listened --
325 only warn about that.
330 @section Release 7.4.0
334 Fixed simultaneous @command{nncp-daemon} and @command{nncp-caller} MCD work.
339 @section Release 7.3.2
343 @command{hjson-cli} utility builds in vendor-mode now.
348 @section Release 7.3.1
352 Fixed possibly left opened file descriptor in online commands.
355 Severely decreased memory usage of MTH hashing.
360 @section Release 7.3.0
364 Fixed some workability problems on 32-bit systems with big files.
367 Ability to use directory with a bunch of files as a configuration.
368 @command{nncp-cfgdir} command appeared.
373 @section Release 7.2.1
377 Small optimizations in online commands.
382 @section Release 7.2.0
386 @command{nncp-trns} command appeared for manual transition packets creation.
389 If destination node of transitional packet has non empty @option{via}
390 route, then do not ignore, but use it.
393 Do not relay multicast packet to area message's originator, that
394 obviously has seen its own packet.
397 Much less memory usage during MTH hashing when offset is zero: when
398 packet is not resumed, but for example checked with @command{nncp-check}
404 @section Release 7.1.1
408 Fixed failing directories @code{fsync} after @file{.seen} file creation.
413 @section Release 7.1.0
417 Multicasting areas feature appeared. Implemented merely by an additional
418 plain packet type with @command{nncp-toss}, @command{nncp-file} and
419 @command{nncp-exec} commands modification.
422 Fixed workability of @command{nncp-file} and @command{nncp-exec}
423 commands, that use temporary file (@code{stdin} and @option{-use-tmp}).
426 Fixed disappearing bad return code in @command{nncp-exec} command.
429 Fixed invalid @file{.hdr} generation when transitional packets are used.
432 @option{-all} option appeared in @command{nncp-rm} command, applying to
433 all the nodes at once.
436 @option{-cycle} option appeared in @command{nncp-check} command, looping
437 the check in infinite cycle.
440 @command{nncp-rm} command can take node alias name.
443 @command{nncp-pkt} can parse @file{.hdr} files.
448 @section Release 7.0.0
452 Minimal required Go version is 1.13.
455 Merkle Tree-based Hashing with BLAKE3 (MTH) is used instead of BLAKE2b.
456 Because of that, there are backward @strong{incompatible} changes of
457 encrypted files (everything laying in the spool directory) and
458 @file{.meta} files of chunked transfer.
460 Current implementation is far from being optimal: it lacks
461 parallelizable calculations and has higher memory consumption: nearly
462 512 KiB for each 1 GiB of file's data. Future performance and memory
463 size optimizations should not lead to packet's format change. But it is
464 still several times faster than BLAKE2b.
467 Resumed online downloads, because of MTH, require reading only of the
468 preceding part of file, not the whole one as was before.
471 @command{nncp-hash} utility appeared for calculating file's MTH hash.
474 BLAKE2 KDF and XOF functions are replaced with BLAKE3 in encrypted
475 packets. Lowering number of used primitives. Also, its encrypted
476 packet's header is used as an associated data during encryption.
479 MultiCast Discovery uses
480 @verb{|ff02::4e4e:4350|} address instead of @verb{|ff02::1|}.
483 @command{nncp-cfgenc} mistakenly asked passphrase three times during encryption.
486 @command{nncp-stat} reports about partly downloaded packets.
489 Updated dependencies.
494 @section Release 6.6.0
498 @command{nncp-daemon}, @command{nncp-call} and @command{nncp-caller}
499 commands wait for all background checksummers completion after
500 connection is finished.
503 Added possibility of address determining through multicast announcement
504 in local area network, so called MCD (MultiCast Discovery).
509 @section Release 6.5.0
513 Fixed segfault in @command{nncp-daemon} when SP handshake did not succeed.
516 Fixed possible bad return code ignoring in automatic tosser.
519 Fixed race during file descriptors closing when online protocol call is
520 finished, that could lead to write error of received packet fragment.
523 Kill all packet transmission progress bars in @command{nncp-daemon},
524 @command{nncp-call} and @command{nncp-caller} when call is finished.
529 @section Release 6.4.0
533 Fixed possible race in online protocol, that lead to panic.
538 @section Release 6.3.0
542 Fixed possible panic while showing progress during online protocol.
547 @section Release 6.2.1
551 Three places in logs contained excess @code{%s}.
556 @section Release 6.2.0
560 Returned @command{nncp-caller}'s @option{-autotoss*} options workability.
563 Yet another logging refactoring and simplification.
564 Should be no visible differences to the end user.
569 @section Release 6.1.0
573 Optimization: most commands do not keep opened file descriptors now.
574 Previously you can exceed maximal number of opened files if you have got
575 many packets in the spool directory.
578 Optimization: do not close file descriptor of the file we download
579 online. Previously each chunk lead to expensive open/close calls.
582 Online downloaded files are saved with @file{.nock} (non-checksummed)
583 suffix, waiting either for @command{nncp-check}, or online daemons to
584 perform integrity check.
587 Optimization: files, that are not resumed, are checksummed immediately
588 during the online download, skipping @file{.nock}-intermediate step.
591 Ability to store encrypted packet's header in @file{.hdr} file, close to
592 the packet itself. That can greatly increase performance of packets
593 listing on filesystems with big block's size.
598 @section Release 6.0.0
602 Log uses human readable and easy machine parseable
603 @url{https://www.gnu.org/software/recutils/, recfile} format for the
604 records, instead of structured RFC 3339 lines. Old logs are not readable
605 by @command{nncp-log} anymore.
608 @option{-autotoss*} option workability with @command{nncp-daemon}'s
609 @option{-inetd} mode.
612 Call's @option{when-tx-exists} allows to make a call only when outbound
613 packets exists. Combined with seconds-aware cron expression that can be
614 used as some kind of auto dialler.
617 @command{nncp-cronexpr} command allows you to check validity and
618 expectations of specified cron expression.
623 @section Release 5.6.0
627 @option{-autotoss*} option runs tosser not after the call, but every
628 second while it is active.
631 @option{autotoss}, @option{autotoss-doseen},
632 @option{autotoss-nofile}, @option{autotoss-nofreq},
633 @option{autotoss-noexec}, @option{autotoss-notrns} options available in
634 @option{calls} configuration section. You can configure per-call
635 automatic tosser options.
638 Use vendoring, instead of @env{$GOPATH} overriding during tarball
639 installation, because current minimal Go's version is 1.12 and it
645 @section Release 5.5.1
649 Respect for @env{$BINDIR}, @env{$INFODIR} and @env{$DOCDIR} environment
650 variables in @file{config} during installation.
655 @section Release 5.5.0
659 Bugfixes in @command{nncp-call(er)}/@command{nncp-daemon},
660 @command{nncp-bundle} and @command{nncp-stat}.
663 @command{nncp-rm} has @option{-dryrun} and @option{-older} options now.
666 @command{nncp-exec} has @option{-use-tmp} and @option{-nocompress}
667 options now. Uncompressed packets are not compatible with previous NNCP
671 @command{nncp-call}, @command{nncp-caller} and @command{nncp-daemon} commands
672 have @option{-autotoss*} options for running tosser after call is ended.
675 Updated dependencies. Minimal required Go version is 1.12.
680 @section Release 5.4.1
684 Fixed @code{SENDMAIL} variable usage during the build.
689 @section Release 5.4.0
693 Updated dependencies.
696 Build system is moved from Makefiles to @url{http://cr.yp.to/redo.html, redo}.
697 This should not influence package maintainers, because minimal @command{redo}
698 implementation is included in tarball.
703 @section Release 5.3.3
707 More various error checks.
710 Updated dependencies.
715 @section Release 5.3.2
719 Fixed incorrect logic of @option{onlinedeadline} timeout, where
720 connection won't take into account incoming packets events and will
721 forcefully disconnect.
726 @section Release 5.3.1
730 Fixed @option{onlinedeadline} workability with call addresses that use
731 external commands (@verb{#"|somecmd"#}).
734 @command{nncp-stat} has @option{-pkt} option displaying information
735 about each packet in the spool.
740 @section Release 5.3.0
744 Progress messages contain prefix, describing the running action.
747 Fixed not occurring handshake messages padding.
750 Finish all SP protocol related goroutines, less memory leak.
753 SP protocol generates less socket write calls, thus generating less TCP
757 Check @option{onlinedeadline} and @option{maxonlinetime} options every
758 second, independently from socket reads (up to 10 seconds).
761 Once per minute, if no other traffic exists, PING packets are sent in
762 SP-connection. That allows faster determining of connection unworkability.
765 @command{nncp-toss} uses lock-file to prevent simultaneous tossing.
770 @section Release 5.2.1
774 Fixed SP protocol error handling, sometimes causing program panic.
779 @section Release 5.2.0
783 Most commands by default show oneline operations progress.
784 @option{-progress}, @option{-noprogress} command line options,
785 @option{noprogress} configuration file option appeared.
788 Fixed incorrect @command{nncp-check} command return code, that returned
789 bad code when everything is good.
792 Free disk space check during @command{nncp-bundle -rx} call.
797 @section Release 5.1.2
801 @strong{Critical} vulnerability: remote peers authentication could lead
802 to incorrect identification of remote side, allowing foreign encrypted
806 Bugfix: private and public Noise keys were swapped in newly created
807 configuration files, that lead to inability to authenticate online peers.
810 Explicit directories @code{fsync}-ing for guaranteed files renaming.
815 @section Release 5.1.1
819 Fixed workability of @command{nncp-file} with @option{-chunked 0} option.
824 @section Release 5.1.0
828 @command{nncp-file} can send directories, automatically creating pax
832 Free disk space is checked during outbound packets creation.
835 @option{freq}, @option{freqminsize}, @option{freqchunked} configuration
836 file options replaced with the structure:
837 @option{freq: @{path: @dots{}, minsize: @dots{}, chunked: @dots{}@}}.
840 Added @option{freq.maxsize} configuration file option, forbidding of
841 freq sending larger than specified size.
844 Ability to notify about successfully executed commands (exec) with
845 @option{notify.exec} configuration file option.
850 @section Release 5.0.0
854 @strong{Incompatible} configuration file format change: YAML is
855 replaced with Hjson, due to its simplicity, without noticeable lack
856 of either functionality or convenience.
859 @strong{Incompatible} plain packet format changes. Older versions are
860 not supported. @code{zlib} compression is replaced with
861 @code{Zstandard}, due to its speed and efficiency, despite library
862 version is not mature enough.
865 Ability to call remote nodes via pipe call of external command, not only
869 @command{nncp-cfgnew} generates configuration file with many
870 comments. @option{-nocomments} option can be used for an old
874 Duplicate filenames have @file{.CTR} suffix, instead of @file{CTR}, to
875 avoid possible collisions with @file{.nncp.chunkCTR}.
878 Ability to override process umask through configuration file option.
881 Files and directories are created with 666/777 permissions by default,
882 allowing control with @command{umask}.
885 Updated dependencies.
888 Full usage of go modules for dependencies management
889 (@code{go.cypherpunks.ru/nncp/v5} namespace is used).
892 Forbid any later GNU GPL version autousage
893 (project's licence now is GNU GPLv3-only).
900 @item Workability on GNU/Linux systems and Go 1.10 is fixed.
908 @strong{Incompatible} encrypted and eblob packet format change: AEAD
909 encryption mode with 128 KiB blocks is used now, because previously
910 @command{nncp-toss} did not verify encrypted packet's MAC before feeding
911 decrypted data to external command. Older versions are not supported.
914 Available free space checking before copying in @command{nncp-xfer},
915 @command{nncp-daemon}, @command{nncp-call(er)}.
918 @command{nncp-call} has ability only to list packets on remote node,
919 without their transmission.
922 @command{nncp-call} has ability to transfer only specified packets.
925 Workability of @option{xxrate} preference in @option{calls}
926 configuration file section.
929 Dependant libraries are updated.
935 Begin using of @code{go.mod} subsystem.
942 @item @command{nncp-daemon} can be run as @command{inetd}-service.
950 @command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller} check
951 if @file{.seen} exists and treat it like file was already downloaded.
952 Possibly it was transferred out-of-bound and remote side needs to be
956 If higher priority packet is spooled, then @command{nncp-daemon} will
957 queue its sending first, interrupting lower priority transmissions.
960 Simple packet rate limiter added to online-related tools
961 (@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller}).
964 Ability to specify niceness with symbolic notation:
965 @verb{|NORMAL|}, @verb{|BULK+10|}, @verb{|PRIORITY-5|}, etc.
968 Changed default niceness levels:
969 for @command{nncp-exec} from 64 to 96,
970 for @command{nncp-freq} from 64 to 160,
971 for @command{nncp-file} from 196 to 224.
979 @strong{Incompatible} @emph{bundle} archive format changes and
980 @command{nncp-bundle} workability with Go 1.10+. Bundles must be
981 valid tar archives, but Go 1.9 made them invalid because of long paths
982 inside. NNCP accidentally was dependant on that bug. Explicit adding of
983 @file{NNCP/} directory in archive restores workability with valid tar
991 Ability to disable relaying at all using @verb{|-via -|} command line option.
999 @strong{Incompatible} plain packet format changes. Older versions are
1003 Ability to queue remote command execution, by configuring @option{exec}
1004 option in configuration file and using @command{nncp-exec} command:
1007 @command{nncp-mail} command is replaced with more flexible
1008 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
1009 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
1011 @option{sendmail} configuration file option is replaced with
1012 @option{exec}. @code{sendmail: [@dots{}]} must be replaced with
1013 @code{exec: sendmail: [@dots{}]}.
1017 Ability to override @option{via} configuration option for destination
1018 node via @option{-via} command line option for following commands:
1019 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
1022 Chunked files, having size less than specified chunk size, will be sent
1023 as an ordinary single file.
1026 Exec commands are invoked with additional @env{$NNCP_NICE} and
1027 @env{$NNCP_SELF} environment variables.
1030 Files, that are sent as a reply to freq, have niceness level taken from
1031 the freq packet. You can set desired niceness during @command{nncp-freq}
1032 invocation using @option{-replynice} option.
1035 @command{nncp-toss} command can ignore specified packet types during
1036 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
1040 @command{nncp-file} command uses
1041 @option{FreqMinSize}/@option{FreqChunked} configuration file options
1042 for @option{-minsize}/@option{-chunked} by default. You can turn this
1043 off by specifying zero value.
1048 @section Release 2.0
1052 @strong{Incompatible} encrypted/eblob packet format changes. Older
1053 versions are not supported.
1056 Twofish encryption algorithm is replaced with ChaCha20. It is much more
1057 faster. One cryptographic primitive less.
1060 HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
1061 another cryptographic primitive less (assuming that BLAKE2X is nearly
1062 identical to BLAKE2).
1067 @section Release 1.0
1071 @strong{Incompatible} encrypted packet format changes. Older versions
1075 @command{nncp-bundle} command can either create stream of encrypted
1076 packets, or digest it. It is useful when dealing with
1077 @code{stdin}/@code{stdout} based transmission methods (like writing to
1078 CD-ROM without intermediate prepared ISO image and working with tape
1082 @command{nncp-toss} is able to create @file{.seen} files preventing
1083 duplicate packets receiving.
1086 Single background checksum verifier worker is allowed in
1087 @command{nncp-call}. This is helpful when thousands of small inbound
1088 packets could create many goroutines.
1091 Ability to override path to spool directory and logfile through either
1092 command line argument, or environment variable.
1095 @command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
1096 @file{.part}, @file{.lock} and temporary files.

1113 @section Release 0.10
1116 @command{nncp-freq}'s @file{DST} argument is optional now. Last
1117 @file{SRC} path's element will be used by default.
1121 @section Release 0.9
1124 Fix @option{-rx}/@option{-tx} arguments processing in
1125 @command{nncp-call} command. They were ignored.
1129 @section Release 0.8
1132 Little bugfix in @command{nncp-file} command, where @option{-minsize}
1133 option for unchunked transfer was not in KiBs, but in bytes.
1137 @section Release 0.7
1141 Ability to feed @command{nncp-file} from @code{stdin}, that uses an
1142 encrypted temporary file for that.
1145 Chunked files transmission appeared with corresponding
1146 @command{nncp-reass} command and @option{freqchunked} configuration file
1147 entry. Useful for transferring big files over small storage devices.
1150 @option{freqminsize} configuration file option, analogue to
1151 @option{-minsize} one.
1154 @command{nncp-xfer}'s @option{-force} option is renamed to
1155 @option{-mkdir} for clarity.
