8 @section Release 8.10.0
12 Updated dependant libraries, including Yggdrasil one (its network moved to v0.5).
17 @section Release 8.9.0
21 @command{nncp-toss} command has @option{-gen-ack} option.
22 @command{nncp-daemon}, @command{nncp-caller}, @command{nncp-call}
23 commands have @option{-autotoss-gen-ack} option. They automatically
24 generate ACK packets and store corresponding @file{spool/tx/ack/}
25 references to them, to be able to remove them after the transfer.
28 @code{autotoss-gen-ack} appeared in call configuration.
29 @code{ack} section appeared in neighbour configuration.
32 @command{nncp-rm} command has @option{-ack} option to remove packets
33 referenced by stored @file{spool/tx/ack/} files generated during tossing.
36 Get rid of @command{redo} build system during installation, as there are
37 virtually none dependencies, just only compilation of the Go code.
40 Updated some dependencies.
45 @section Release 8.8.3
49 Fixed @command{nncp-reass} command, that incorrectly reported about
50 wrong last chunk's size if it is multiple of the chunk-size.
53 Updated dependencies. Go 1.20+ is required now.
58 @section Release 8.8.2
62 Updated Yggdrasil library, with several other ones.
67 @section Release 8.8.1
71 Fixed @command{nncp-daemon} failing with unauthenticated connection and
72 enabled @option{-autotoss}.
80 @section Release 8.8.0
84 Fixed buildability under Go 1.19.
87 Minimal required Go version is 1.17.
95 @section Release 8.7.2
99 More intuitive, clear and slightly more flexible behaviour of @command{nncp-rm}.
102 @command{nncp-rm} also removes corresponding @file{hdr/} file for each
108 @section Release 8.7.1
112 @command{nncp-xfer} now correctly checks for @file{seen/} files for
118 @section Release 8.7.0
122 @command{nncp-ack} does not acknowledge ACK-packets, preventing an
123 endless loop of ACKs.
126 @command{nncp-ack} previously did not remove corresponding @file{hdr/} files.
129 @command{nncp-rm} now takes list of packet from @code{stdin} when
130 @option{-pkt} option is used.
133 @command{nncp-ack} now generates list of ACK packets it created, that
134 could be used as an input to @command{nncp-rm} to remove outbound ACK
140 @section Release 8.6.0
144 @command{nncp-xfer} checks if locally copied packet's checksum differs
145 from the source's one.
148 @command{nncp-call} has bad return code if its queues contain unfinished jobs.
151 @command{nncp-ack} command appeared, that sends explicit packet receipt
152 acknowledgement (ACK packet). That acknowledgement deletes referenced
153 packet from the outbound spool.
156 Ability to turn @code{fsync} operation off using @env{$NNCPNOSYNC=1}
157 environment variable.
160 Added various indices in documentation, that should help searching in it.
165 @section Release 8.5.0
169 Fixed @command{nncp-bundle} workability.
172 Mistakenly @option{-mcd-wait} option was enabled by default in
176 Ability to override internal default timeout for online protocol through
177 @env{$NNCPDEADLINE} environment variable. Can be useful for very high
181 NNCP builds on OpenBSD.
186 @section Release 8.4.0
190 Multicast related interface names (@code{mcd-listen} and @code{mcd-send}
191 configuration options) are now regular expressions. By default
192 @command{nncp-cfgnew} uncomments them now with @code{.*} interface name.
195 @command{nncp-call} command has @option{-mcd-wait} option to wait for
196 multicast packet about node's address.
199 @command{nncp-file} command skips everything that is neither regular
200 file nor directory during pax-archive creation.
205 @section Release 8.3.0
209 Fixed building issues on 32-bit systems.
214 @section Release 8.2.0
218 Yggdrasil uses pure-Go IPv6+TCP network stack, instead of naked μTP
219 transport protocol, making it able to work as an ordinary TCP server
220 inside overlay network.
223 Yggdrasil's @code{prv;bind1,bind2;pub@dots{}}-like configuration strings are
224 replaced with URL-like ones (@code{yggdrasils://PRV?bind=BIND1&bind=BIND2&pub=PUB}).
227 Ability to pass multicast-related parameters to Yggdrasil configuration.
230 @command{nncp-daemon} is able to listen on both TCP and Yggdrasil-driven
231 sockets simultaneously.
234 @command{nncp-daemon}'s listening on peering endpoint socket is optional
235 -- you can be reached through the peers.
240 @section Release 8.1.0
244 @command{nncp-cfgdir} does not require @code{self} section existence in
248 Ability to act as Yggdrasil network client, using online protocol on top of it.
253 @section Release 8.0.2
257 Fixed sending ability to areas.
262 @section Release 8.0.1
266 Fixed incorrect @code{freq.chunked} value calculation. If it was missed,
267 then chunked transfer mode was forcefully turned on anyway.
270 Fixed incorrect full file's size calculation in @file{.nncp.meta}.
275 @section Release 8.0.0
279 @strong{Incompatible} encrypted packet format change: payload and pad
280 sizes are sent in-bound in the encrypted stream. That gives ability to
281 streamingly create encrypted packets, without knowing sizes in advance,
282 without creating temporary file or buffer data in memory.
285 Proper encrypted packet padding verification is done now. This is not
286 critical issue, but previously neither padding value, nor its size were
287 authenticated, giving ability to iteratively strip trailing bytes and
288 determine payload's size by observing the reaction of the encrypted
292 @command{nncp-exec} loses its @option{-use-tmp} option, because of
293 streaming-compatible encrypted packets format.
296 @command{nncp-file} and @command{nncp-exec} commands have
297 @option{-maxsize} option, limiting maximal resulting encrypted packet's
298 maximal size (returning error if it is exceeded). Could be useful,
299 because no payload size could be known in advance.
304 @section Release 7.7.0
308 Experimental @code{kqueue} and @code{inotify} based notifications
309 support about spool directory changes, for reducing their often reading
313 @file{.seen} and @file{.hdr} files moved to @file{seen/} and @file{hdr/}
314 subdirectories, for faster scanning of spool directories.
315 Current files migration required:
318 $ find $NNCPSPOOL -type f -name "*.hdr" -exec rm @{@} +
320 $ find $NNCPSPOOL -type d -name rx | while read rx ; do
323 find . -type f -name "*.seen" | while read fn ; do
324 mv $fn seen/$@{fn%.seen@}
328 $ find $NNCPSPOOL -type d -name area | while read area ; do
329 find $area -type f -name "*.seen" | while read fn ; do
338 @section Release 7.6.0
342 Logging may be done to specified opened file descriptor
343 (@env{$NNCPLOG=FD:5} for example).
344 That is friendly to use under @command{daemontools}.
347 Added additional checks of public keys existence in configuration file,
348 preventing some commands from failing.
353 @section Release 7.5.1
357 NNCP builds on NetBSD.
362 @section Release 7.5.0
366 @command{nncp-daemon} is compatible with UCSPI-TCP interface, so log
367 will contain remote side's address (when running under appropriate
368 utility). @option{-ucspi} option should be used instead of @option{-inetd}.
371 @command{nncp-call} can be UCSPI-TCP client, using @option{-ucspi} option.
374 Do not exit if some of MCD network interfaces can not be listened --
375 only warn about that.
380 @section Release 7.4.0
384 Fixed simultaneous @command{nncp-daemon} and @command{nncp-caller} MCD work.
389 @section Release 7.3.2
393 @command{hjson-cli} utility builds in vendor-mode now.
398 @section Release 7.3.1
402 Fixed possibly left opened file descriptor in online commands.
405 Severely decreased memory usage of MTH hashing.
410 @section Release 7.3.0
414 Fixed some workability problems on 32-bit systems with big files.
417 Ability to use directory with a bunch of files as a configuration.
418 @command{nncp-cfgdir} command appeared.
423 @section Release 7.2.1
427 Small optimizations in online commands.
432 @section Release 7.2.0
436 @command{nncp-trns} command appeared for manual transition packets creation.
439 If destination node of transitional packet has non empty @option{via}
440 route, then do not ignore, but use it.
443 Do not relay multicast packet to area message's originator, that
444 obviously has seen its own packet.
447 Much less memory usage during MTH hashing when offset is zero: when
448 packet is not resumed, but for example checked with @command{nncp-check}
454 @section Release 7.1.1
458 Fixed failing directories @code{fsync} after @file{.seen} file creation.
463 @section Release 7.1.0
467 Multicasting areas feature appeared. Implemented merely by an additional
468 plain packet type with @command{nncp-toss}, @command{nncp-file} and
469 @command{nncp-exec} commands modification.
472 Fixed workability of @command{nncp-file} and @command{nncp-exec}
473 commands, that use temporary file (@code{stdin} and @option{-use-tmp}).
476 Fixed disappearing bad return code in @command{nncp-exec} command.
479 Fixed invalid @file{.hdr} generation when transitional packets are used.
482 @option{-all} option appeared in @command{nncp-rm} command, applying to
483 all the nodes at once.
486 @option{-cycle} option appeared in @command{nncp-check} command, looping
487 the check in infinite cycle.
490 @command{nncp-rm} command can take node alias name.
493 @command{nncp-pkt} can parse @file{.hdr} files.
498 @section Release 7.0.0
502 Minimal required Go version is 1.13.
505 Merkle Tree-based Hashing with BLAKE3 (MTH) is used instead of BLAKE2b.
506 Because of that, there are backward @strong{incompatible} changes of
507 encrypted files (everything laying in the spool directory) and
508 @file{.meta} files of chunked transfer.
510 Current implementation is far from being optimal: it lacks
511 parallelizable calculations and has higher memory consumption: nearly
512 512 KiB for each 1 GiB of file's data. Future performance and memory
513 size optimizations should not lead to packet's format change. But it is
514 still several times faster than BLAKE2b.
517 Resumed online downloads, because of MTH, require reading only of the
518 preceding part of file, not the whole one as was before.
521 @command{nncp-hash} utility appeared for calculating file's MTH hash.
524 BLAKE2 KDF and XOF functions are replaced with BLAKE3 in encrypted
525 packets. Lowering number of used primitives. Also, its encrypted
526 packet's header is used as an associated data during encryption.
529 MultiCast Discovery uses
530 @verb{|ff02::4e4e:4350|} address instead of @verb{|ff02::1|}.
533 @command{nncp-cfgenc} mistakenly asked passphrase three times during encryption.
536 @command{nncp-stat} reports about partly downloaded packets.
539 Updated dependencies.
544 @section Release 6.6.0
548 @command{nncp-daemon}, @command{nncp-call} and @command{nncp-caller}
549 commands wait for all background checksummers completion after
550 connection is finished.
553 Added possibility of address determining through multicast announcement
554 in local area network, so called MCD (MultiCast Discovery).
559 @section Release 6.5.0
563 Fixed segfault in @command{nncp-daemon} when SP handshake did not succeed.
566 Fixed possible bad return code ignoring in automatic tosser.
569 Fixed race during file descriptors closing when online protocol call is
570 finished, that could lead to write error of received packet fragment.
573 Kill all packet transmission progress bars in @command{nncp-daemon},
574 @command{nncp-call} and @command{nncp-caller} when call is finished.
579 @section Release 6.4.0
583 Fixed possible race in online protocol, that lead to panic.
588 @section Release 6.3.0
592 Fixed possible panic while showing progress during online protocol.
597 @section Release 6.2.1
601 Three places in logs contained excess @code{%s}.
606 @section Release 6.2.0
610 Returned @command{nncp-caller}'s @option{-autotoss*} options workability.
613 Yet another logging refactoring and simplification.
614 Should be no visible differences to the end user.
619 @section Release 6.1.0
623 Optimization: most commands do not keep opened file descriptors now.
624 Previously you can exceed maximal number of opened files if you have got
625 many packets in the spool directory.
628 Optimization: do not close file descriptor of the file we download
629 online. Previously each chunk lead to expensive open/close calls.
632 Online downloaded files are saved with @file{.nock} (non-checksummed)
633 suffix, waiting either for @command{nncp-check}, or online daemons to
634 perform integrity check.
637 Optimization: files, that are not resumed, are checksummed immediately
638 during the online download, skipping @file{.nock}-intermediate step.
641 Ability to store encrypted packet's header in @file{.hdr} file, close to
642 the packet itself. That can greatly increase performance of packets
643 listing on filesystems with big block's size.
648 @section Release 6.0.0
652 Log uses human readable and easy machine parseable
653 @url{https://www.gnu.org/software/recutils/, recfile} format for the
654 records, instead of structured RFC 3339 lines. Old logs are not readable
655 by @command{nncp-log} anymore.
658 @option{-autotoss*} option workability with @command{nncp-daemon}'s
659 @option{-inetd} mode.
662 Call's @option{when-tx-exists} allows to make a call only when outbound
663 packets exists. Combined with seconds-aware cron expression that can be
664 used as some kind of auto dialler.
667 @command{nncp-cronexpr} command allows you to check validity and
668 expectations of specified cron expression.
673 @section Release 5.6.0
677 @option{-autotoss*} option runs tosser not after the call, but every
678 second while it is active.
681 @option{autotoss}, @option{autotoss-doseen},
682 @option{autotoss-nofile}, @option{autotoss-nofreq},
683 @option{autotoss-noexec}, @option{autotoss-notrns} options available in
684 @option{calls} configuration section. You can configure per-call
685 automatic tosser options.
688 Use vendoring, instead of @env{$GOPATH} overriding during tarball
689 installation, because current minimal Go's version is 1.12 and it
695 @section Release 5.5.1
699 Respect for @env{$BINDIR}, @env{$INFODIR} and @env{$DOCDIR} environment
700 variables in @file{config} during installation.
705 @section Release 5.5.0
709 Bugfixes in @command{nncp-call(er)}/@command{nncp-daemon},
710 @command{nncp-bundle} and @command{nncp-stat}.
713 @command{nncp-rm} has @option{-dryrun} and @option{-older} options now.
716 @command{nncp-exec} has @option{-use-tmp} and @option{-nocompress}
717 options now. Uncompressed packets are not compatible with previous NNCP
721 @command{nncp-call}, @command{nncp-caller} and @command{nncp-daemon} commands
722 have @option{-autotoss*} options for running tosser after call is ended.
725 Updated dependencies. Minimal required Go version is 1.12.
730 @section Release 5.4.1
734 Fixed @code{SENDMAIL} variable usage during the build.
739 @section Release 5.4.0
743 Updated dependencies.
746 Build system is moved from Makefiles to @url{http://cr.yp.to/redo.html, redo}.
747 This should not influence package maintainers, because minimal @command{redo}
748 implementation is included in tarball.
753 @section Release 5.3.3
757 More various error checks.
760 Updated dependencies.
765 @section Release 5.3.2
769 Fixed incorrect logic of @option{onlinedeadline} timeout, where
770 connection won't take into account incoming packets events and will
771 forcefully disconnect.
776 @section Release 5.3.1
780 Fixed @option{onlinedeadline} workability with call addresses that use
781 external commands (@verb{#"|somecmd"#}).
784 @command{nncp-stat} has @option{-pkt} option displaying information
785 about each packet in the spool.
790 @section Release 5.3.0
794 Progress messages contain prefix, describing the running action.
797 Fixed not occurring handshake messages padding.
800 Finish all SP protocol related goroutines, less memory leak.
803 SP protocol generates less socket write calls, thus generating less TCP
807 Check @option{onlinedeadline} and @option{maxonlinetime} options every
808 second, independently from socket reads (up to 10 seconds).
811 Once per minute, if no other traffic exists, PING packets are sent in
812 SP-connection. That allows faster determining of connection unworkability.
815 @command{nncp-toss} uses lock-file to prevent simultaneous tossing.
820 @section Release 5.2.1
824 Fixed SP protocol error handling, sometimes causing program panic.
829 @section Release 5.2.0
833 Most commands by default show oneline operations progress.
834 @option{-progress}, @option{-noprogress} command line options,
835 @option{noprogress} configuration file option appeared.
838 Fixed incorrect @command{nncp-check} command return code, that returned
839 bad code when everything is good.
842 Free disk space check during @command{nncp-bundle -rx} call.
847 @section Release 5.1.2
851 @strong{Critical} vulnerability: remote peers authentication could lead
852 to incorrect identification of remote side, allowing foreign encrypted
856 Bugfix: private and public Noise keys were swapped in newly created
857 configuration files, that lead to inability to authenticate online peers.
860 Explicit directories @code{fsync}-ing for guaranteed files renaming.
865 @section Release 5.1.1
869 Fixed workability of @command{nncp-file} with @option{-chunked 0} option.
874 @section Release 5.1.0
878 @command{nncp-file} can send directories, automatically creating pax
882 Free disk space is checked during outbound packets creation.
885 @option{freq}, @option{freqminsize}, @option{freqchunked} configuration
886 file options replaced with the structure:
887 @option{freq: @{path: @dots{}, minsize: @dots{}, chunked: @dots{}@}}.
890 Added @option{freq.maxsize} configuration file option, forbidding of
891 freq sending larger than specified size.
894 Ability to notify about successfully executed commands (exec) with
895 @option{notify.exec} configuration file option.
900 @section Release 5.0.0
904 @strong{Incompatible} configuration file format change: YAML is
905 replaced with Hjson, due to its simplicity, without noticeable lack
906 of either functionality or convenience.
909 @strong{Incompatible} plain packet format changes. Older versions are
910 not supported. @code{zlib} compression is replaced with
911 @code{Zstandard}, due to its speed and efficiency, despite library
912 version is not mature enough.
915 Ability to call remote nodes via pipe call of external command, not only
919 @command{nncp-cfgnew} generates configuration file with many
920 comments. @option{-nocomments} option can be used for an old
924 Duplicate filenames have @file{.CTR} suffix, instead of @file{CTR}, to
925 avoid possible collisions with @file{.nncp.chunkCTR}.
928 Ability to override process umask through configuration file option.
931 Files and directories are created with 666/777 permissions by default,
932 allowing control with @command{umask}.
935 Updated dependencies.
938 Full usage of go modules for dependencies management
939 (@code{go.cypherpunks.ru/nncp/v5} namespace is used).
942 Forbid any later GNU GPL version autousage
943 (project's licence now is GNU GPLv3-only).
950 @item Workability on GNU/Linux systems and Go 1.10 is fixed.
958 @strong{Incompatible} encrypted and eblob packet format change: AEAD
959 encryption mode with 128 KiB blocks is used now, because previously
960 @command{nncp-toss} did not verify encrypted packet's MAC before feeding
961 decrypted data to external command. Older versions are not supported.
964 Available free space checking before copying in @command{nncp-xfer},
965 @command{nncp-daemon}, @command{nncp-call(er)}.
968 @command{nncp-call} has ability only to list packets on remote node,
969 without their transmission.
972 @command{nncp-call} has ability to transfer only specified packets.
975 Workability of @option{xxrate} preference in @option{calls}
976 configuration file section.
979 Dependant libraries are updated.
985 Begin using of @code{go.mod} subsystem.
992 @item @command{nncp-daemon} can be run as @command{inetd}-service.
1000 @command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller} check
1001 if @file{.seen} exists and treat it like file was already downloaded.
1002 Possibly it was transferred out-of-bound and remote side needs to be
1003 notifier about that.
1006 If higher priority packet is spooled, then @command{nncp-daemon} will
1007 queue its sending first, interrupting lower priority transmissions.
1010 Simple packet rate limiter added to online-related tools
1011 (@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller}).
1014 Ability to specify niceness with symbolic notation:
1015 @verb{|NORMAL|}, @verb{|BULK+10|}, @verb{|PRIORITY-5|}, etc.
1018 Changed default niceness levels:
1019 for @command{nncp-exec} from 64 to 96,
1020 for @command{nncp-freq} from 64 to 160,
1021 for @command{nncp-file} from 196 to 224.
1026 @section Release 3.2
1029 @strong{Incompatible} @emph{bundle} archive format changes and
1030 @command{nncp-bundle} workability with Go 1.10+. Bundles must be
1031 valid tar archives, but Go 1.9 made them invalid because of long paths
1032 inside. NNCP accidentally was dependant on that bug. Explicit adding of
1033 @file{NNCP/} directory in archive restores workability with valid tar
1038 @section Release 3.1
1041 Ability to disable relaying at all using @verb{|-via -|} command line option.
1045 @section Release 3.0
1049 @strong{Incompatible} plain packet format changes. Older versions are
1053 Ability to queue remote command execution, by configuring @option{exec}
1054 option in configuration file and using @command{nncp-exec} command:
1057 @command{nncp-mail} command is replaced with more flexible
1058 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
1059 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
1061 @option{sendmail} configuration file option is replaced with
1062 @option{exec}. @code{sendmail: [@dots{}]} must be replaced with
1063 @code{exec: sendmail: [@dots{}]}.
1067 Ability to override @option{via} configuration option for destination
1068 node via @option{-via} command line option for following commands:
1069 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
1072 Chunked files, having size less than specified chunk size, will be sent
1073 as an ordinary single file.
1076 Exec commands are invoked with additional @env{$NNCP_NICE} and
1077 @env{$NNCP_SELF} environment variables.
1080 Files, that are sent as a reply to freq, have niceness level taken from
1081 the freq packet. You can set desired niceness during @command{nncp-freq}
1082 invocation using @option{-replynice} option.
1085 @command{nncp-toss} command can ignore specified packet types during
1086 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
1090 @command{nncp-file} command uses
1091 @option{FreqMinSize}/@option{FreqChunked} configuration file options
1092 for @option{-minsize}/@option{-chunked} by default. You can turn this
1093 off by specifying zero value.
1098 @section Release 2.0
1102 @strong{Incompatible} encrypted/eblob packet format changes. Older
1103 versions are not supported.
1106 Twofish encryption algorithm is replaced with ChaCha20. It is much more
1107 faster. One cryptographic primitive less.
1110 HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
1111 another cryptographic primitive less (assuming that BLAKE2X is nearly
1112 identical to BLAKE2).
1117 @section Release 1.0
1121 @strong{Incompatible} encrypted packet format changes. Older versions
1125 @command{nncp-bundle} command can either create stream of encrypted
1126 packets, or digest it. It is useful when dealing with
1127 @code{stdin}/@code{stdout} based transmission methods (like writing to
1128 CD-ROM without intermediate prepared ISO image and working with tape
1132 @command{nncp-toss} is able to create @file{.seen} files preventing
1133 duplicate packets receiving.
1136 Single background checksum verifier worker is allowed in
1137 @command{nncp-call}. This is helpful when thousands of small inbound
1138 packets could create many goroutines.
1141 Ability to override path to spool directory and logfile through either
1142 command line argument, or environment variable.
1145 @command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
