11 Three places in logs contained excess @code{%s}.
16 @section Release 6.2.0
20 Returned @command{nncp-caller}'s @option{-autotoss*} options workability.
23 Yet another logging refactoring and simplification.
24 Should be no visible differences to the end user.
29 @section Release 6.1.0
33 Optimization: most commands do not keep opened file descriptors now.
34 Previously you can exceed maximal number of opened files if you have got
35 many packets in the spool directory.
38 Optimization: do not close file descriptor of the file we download
39 online. Previously each chunk lead to expensive open/close calls.
42 Online downloaded files are saved with @file{.nock} (non-checksummed)
43 suffix, waiting either for @command{nncp-check}, or online daemons to
44 perform integrity check.
47 Optimization: files, that are not resumed, are checksummed immediately
48 during the online download, skipping @file{.nock}-intermediate step.
51 Ability to store encrypted packet's header in @file{.hdr} file, close to
52 the packet itself. That can greatly increase performance of packets
53 listing on filesystems with big block's size.
58 @section Release 6.0.0
62 Log uses human readable and easy machine parseable
63 @url{https://www.gnu.org/software/recutils/, recfile} format for the
64 records, instead of structured RFC 3339 lines. Old logs are not readable
65 by @command{nncp-log} anymore.
68 @option{-autotoss*} option workability with @command{nncp-daemon}'s
72 Call's @option{when-tx-exists} allows to make a call only when outbound
73 packets exists. Combined with seconds-aware cron expression that can be
74 used as some kind of auto dialler.
77 @command{nncp-cronexpr} command allows you to check validity and
78 expectations of specified cron expression.
83 @section Release 5.6.0
87 @option{-autotoss*} option runs tosser not after the call, but every
88 second while it is active.
91 @option{autotoss}, @option{autotoss-doseen},
92 @option{autotoss-nofile}, @option{autotoss-nofreq},
93 @option{autotoss-noexec}, @option{autotoss-notrns} options available in
94 @option{calls} configuration section. You can configure per-call
95 automatic tosser options.
98 Use vendoring, instead of @env{GOPATH} overriding during tarball
99 installation, because current minimal Go's version is 1.12 and it
105 @section Release 5.5.1
109 Respect for @env{BINDIR}, @env{INFODIR} and @env{DOCDIR} environment
110 variables in @file{config} during installation.
115 @section Release 5.5.0
119 Bugfixes in @command{nncp-call(er)}/@command{nncp-daemon},
120 @command{nncp-bundle} and @command{nncp-stat}.
123 @command{nncp-rm} has @option{-dryrun} and @option{-older} options now.
126 @command{nncp-exec} has @option{-use-tmp} and @option{-nocompress}
127 options now. Uncompressed packets are not compatible with previous NNCP
131 @command{nncp-call}, @command{nncp-caller} and @command{nncp-daemon} commands
132 have @option{-autotoss*} options for running tosser after call is ended.
135 Updated dependencies. Minimal required Go version is 1.12.
140 @section Release 5.4.1
144 Fixed @code{SENDMAIL} variable usage during the build.
149 @section Release 5.4.0
153 Updated dependencies.
156 Build system is moved from Makefiles to @url{http://cr.yp.to/redo.html, redo}.
157 This should not influence package maintainers, because minimal @command{redo}
158 implementation is included in tarball.
163 @section Release 5.3.3
167 More various error checks.
170 Updated dependencies.
175 @section Release 5.3.2
179 Fixed incorrect logic of @option{onlinedeadline} timeout, where
180 connection won't take into account incoming packets events and will
181 forcefully disconnect.
186 @section Release 5.3.1
190 Fixed @option{onlinedeadline} workability with call addresses that use
191 external commands (@verb{#"|somecmd"#}).
194 @command{nncp-stat} has @option{-pkt} option displaying information
195 about each packet in the spool.
200 @section Release 5.3.0
204 Progress messages contain prefix, describing the running action.
207 Fixed not occurring handshake messages padding.
210 Finish all SP protocol related goroutines, less memory leak.
213 SP protocol generates less socket write calls, thus generating less TCP
217 Check @option{onlinedeadline} and @option{maxonlinetime} options every
218 second, independently from socket reads (up to 10 seconds).
221 Once per minute, if no other traffic exists, PING packets are sent in
222 SP-connection. That allows faster determining of connection unworkability.
225 @command{nncp-toss} uses lock-file to prevent simultaneous tossing.
230 @section Release 5.2.1
234 Fixed SP protocol error handling, sometimes causing program panic.
239 @section Release 5.2.0
243 Most commands by default show oneline operations progress.
244 @option{-progress}, @option{-noprogress} command line options,
245 @option{noprogress} configuration file option appeared.
248 Fixed incorrect @command{nncp-check} command return code, that returned
249 bad code when everything is good.
252 Free disk space check during @command{nncp-bundle -rx} call.
257 @section Release 5.1.2
261 @strong{Critical} vulnerability: remote peers authentication could lead
262 to incorrect identification of remote side, allowing foreign encrypted
266 Bugfix: private and public Noise keys were swapped in newly created
267 configuration files, that lead to inability to authenticate online peers.
270 Explicit directories fsync-ing for guaranteed files renaming.
275 @section Release 5.1.1
279 Fixed workability of @command{nncp-file} with @option{-chunked 0} option.
284 @section Release 5.1.0
288 @command{nncp-file} can send directories, automatically creating pax
292 Free disk space is checked during outbound packets creation.
295 @option{freq}, @option{freqminsize}, @option{freqchunked} configuration
296 file options replaced with the structure:
297 @option{freq: @{path: ..., minsize: ..., chunked: ...@}}.
300 Added @option{freq.maxsize} configuration file option, forbidding of
301 freq sending larger than specified size.
304 Ability to notify about successfully executed commands (exec) with
305 @option{notify.exec} configuration file option.
310 @section Release 5.0.0
314 @strong{Incompatible} configuration file format change: YAML is
315 replaced with Hjson, due to its simplicity, without noticeable lack
316 of either functionality or convenience.
319 @strong{Incompatible} plain packet format changes. Older versions are
320 not supported. @code{zlib} compression is replaced with
321 @code{Zstandard}, due to its speed and efficiency, despite library
322 version is not mature enough.
325 Ability to call remote nodes via pipe call of external command, not only
329 @command{nncp-cfgnew} generates configuration file with many
330 comments. @option{-nocomments} option can be used for an old
334 Duplicate filenames have @file{.CTR} suffix, instead of @file{CTR}, to
335 avoid possible collisions with @file{.nncp.chunkCTR}.
338 Ability to override process umask through configuration file option.
341 Files and directories are created with 666/777 permissions by default,
342 allowing control with @command{umask}.
345 Updated dependencies.
348 Full usage of go modules for dependencies management
349 (@code{go.cypherpunks.ru/nncp/v5} namespace is used).
352 Forbid any later GNU GPL version autousage
353 (project's licence now is GNU GPLv3-only).
360 @item Workability on GNU/Linux systems and Go 1.10 is fixed.
368 @strong{Incompatible} encrypted and eblob packet format change: AEAD
369 encryption mode with 128 KiB blocks is used now, because previously
370 @command{nncp-toss} did not verify encrypted packet's MAC before feeding
371 decrypted data to external command. Older versions are not supported.
374 Available free space checking before copying in @command{nncp-xfer},
375 @command{nncp-daemon}, @command{nncp-call(er)}.
378 @command{nncp-call} has ability only to list packets on remote node,
379 without their transmission.
382 @command{nncp-call} has ability to transfer only specified packets.
385 Workability of @option{xxrate} preference in @option{calls}
386 configuration file section.
389 Dependant libraries are updated.
395 Begin using of @code{go.mod} subsystem.
402 @item @command{nncp-daemon} can be run as @command{inetd}-service.
410 @command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller} check
411 if @file{.seen} exists and treat it like file was already downloaded.
412 Possibly it was transferred out-of-bound and remote side needs to be
416 If higher priority packet is spooled, then @command{nncp-daemon} will
417 queue its sending first, interrupting lower priority transmissions.
420 Simple packet rate limiter added to online-related tools
421 (@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller}).
424 Ability to specify niceness with symbolic notation:
425 @verb{|NORMAL|}, @verb{|BULK+10|}, @verb{|PRIORITY-5|}, etc.
428 Changed default niceness levels:
429 for @command{nncp-exec} from 64 to 96,
430 for @command{nncp-freq} from 64 to 160,
431 for @command{nncp-file} from 196 to 224.
439 @strong{Incompatible} @emph{bundle} archive format changes and
440 @command{nncp-bundle} workability with Go 1.10+. Bundles must be
441 valid tar archives, but Go 1.9 made them invalid because of long paths
442 inside. NNCP accidentally was dependant on that bug. Explicit adding of
443 @file{NNCP/} directory in archive restores workability with valid tar
451 Ability to disable relaying at all using @verb{|-via -|} command line option.
459 @strong{Incompatible} plain packet format changes. Older versions are
463 Ability to queue remote command execution, by configuring @option{exec}
464 option in configuration file and using @command{nncp-exec} command:
467 @command{nncp-mail} command is replaced with more flexible
468 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
469 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
471 @option{sendmail} configuration file option is replaced with
472 @option{exec}. @verb{|sendmail: [...]|} must be replaced with
473 @verb{|exec: sendmail: [...]|}.
477 Ability to override @option{via} configuration option for destination
478 node via @option{-via} command line option for following commands:
479 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
482 Chunked files, having size less than specified chunk size, will be sent
483 as an ordinary single file.
486 Exec commands are invoked with additional @env{NNCP_NICE} and
487 @env{NNCP_SELF} environment variables.
490 Files, that are sent as a reply to freq, have niceness level taken from
491 the freq packet. You can set desired niceness during @command{nncp-freq}
492 invocation using @option{-replynice} option.
495 @command{nncp-toss} command can ignore specified packet types during
496 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
500 @command{nncp-file} command uses
501 @option{FreqMinSize}/@option{FreqChunked} configuration file options
502 for @option{-minsize}/@option{-chunked} by default. You can turn this
503 off by specifying zero value.
512 @strong{Incompatible} encrypted/eblob packet format changes. Older
513 versions are not supported.
516 Twofish encryption algorithm is replaced with ChaCha20. It is much more
517 faster. One cryptographic primitive less.
520 HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
521 another cryptographic primitive less (assuming that BLAKE2X is nearly
522 identical to BLAKE2).
531 @strong{Incompatible} encrypted packet format changes. Older versions
535 @command{nncp-bundle} command can either create stream of encrypted
536 packets, or digest it. It is useful when dealing with
537 @code{stdin}/@code{stdout} based transmission methods (like writing to
538 CD-ROM without intermediate prepared ISO image and working with tape
542 @command{nncp-toss} is able to create @file{.seen} files preventing
543 duplicate packets receiving.
546 Single background checksum verifier worker is allowed in
547 @command{nncp-call}. This is helpful when thousands of small inbound
548 packets could create many goroutines.
551 Ability to override path to spool directory and logfile through either
552 command line argument, or environment variable.
555 @command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
556 @file{.part}, @file{.lock} and temporary files.
561 @section Release 0.12
563 @item Sendmail command is called with @env{NNCP_SENDER} environment variable.
567 @section Release 0.11
569 @item @command{nncp-stat}'s command output is sorted by node name.
573 @section Release 0.10
576 @command{nncp-freq}'s @file{DST} argument is optional now. Last
577 @file{SRC} path's element will be used by default.
584 Fix @option{-rx}/@option{-tx} arguments processing in
585 @command{nncp-call} command. They were ignored.
592 Little bugfix in @command{nncp-file} command, where @option{-minsize}
593 option for unchunked transfer was not in KiBs, but in bytes.
601 Ability to feed @command{nncp-file} from @code{stdin}, that uses an
602 encrypted temporary file for that.
605 Chunked files transmission appeared with corresponding
606 @command{nncp-reass} command and @option{freqchunked} configuration file
607 entry. Useful for transferring big files over small storage devices.
610 @option{freqminsize} configuration file option, analogue to
611 @option{-minsize} one.
614 @command{nncp-xfer}'s @option{-force} option is renamed to
615 @option{-mkdir} for clarity.
618 @option{-minsize} option is specified in KiBs, not bytes, for
622 @command{nncp-newcfg} command is renamed to @command{nncp-cfgnew},
623 and @command{nncp-mincfg} to @command{nncp-cfgmin} -- now they have
624 common prefix and are grouped together for convenience.
627 @command{nncp-cfgenc} command appeared, allowing configuration file
628 encryption/decryption, for keeping it safe without any either OpenPGP or
632 Cryptographic libraries (dependencies) are updated.
639 @item Small @command{nncp-rm} command appeared.
640 @item Cryptographic libraries (dependencies) are updated.
647 Trivial small fix in default niceness level of @command{nncp-file}
648 and @command{nncp-freq} commands.
656 Small fix in @command{nncp-call}, @command{nncp-caller},
657 @command{nncp-daemon}: they can segmentation fail sometimes (no data is
661 @command{nncp-newnode} renamed to @command{nncp-newcfg} -- it is shorter
662 and more convenient to use.
665 @command{nncp-mincfg} command appeared: helper allowing to create
666 minimalistic stripped down configuration file without private keys, that
667 is useful during @command{nncp-xfer} usage.
674 @item Fixed compatibility with Go 1.6.
682 @strong{Incompatible} packet's format change (magic number is changed
683 too): size field is encrypted and is not send in plaintext anymore.
686 @option{-minsize} option gives ability to automatically pad outgoing
687 packets to specified minimal size.
690 @command{nncp-daemon} and @command{nncp-call}/@command{nncp-caller}
691 always check new @emph{tx} packets appearance in the background while
692 connected. Remote side is immediately notified.
695 @option{-onlinedeadline} option gives ability to configure timeout of
696 inactivity of online connection, when it could be disconnected. It could
697 be used to keep connection alive for a long time.
700 @option{-maxonlinetime} option gives ability to set maximal allowable
701 online connection aliveness time.
704 @command{nncp-caller} command appeared: cron-ed TCP daemon caller.
707 @command{nncp-pkt} command can decompress the data.
