9 @item Files and directories are created with 666/777 permissions by
10 default, allowing control with @command{umask}.
11 @item Updated dependencies.
12 @item Full usage of go modules for dependencies management
13 (@code{go.cypherpunks.ru/nncp/v4} namespace is used).
20 Workability on GNU/Linux systems and Go 1.10 is fixed.
27 @strong{Incompatible} encrypted and eblob packet format change: AEAD
28 encryption mode with 128 KiB blocks is used now, because previously
29 @command{nncp-toss} did not verify encrypted packet's MAC before feeding
30 decrypted data to external command. Older versions are not supported.
32 Available free space checking before copying in @command{nncp-xfer},
33 @command{nncp-daemon}, @command{nncp-call(er)}.
35 @command{nncp-call} has ability only to list packets on remote node,
36 without their transmission.
38 @command{nncp-call} has ability to transfer only specified packets.
40 Workability of @option{xxrate} preference in @option{calls}
41 configuration file section.
43 Dependant libraries are updated.
47 Begin using of @code{go.mod} subsystem.
54 @command{nncp-daemon} can be run as @command{inetd}-service.
61 @command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller} check
62 if @file{.seen} exists and treat it like file was already downloaded.
63 Possibly it was transferred out-of-bound and remote side needs to be
66 If higher priority packet is spooled, then @command{nncp-daemon} will
67 queue its sending first, interrupting lower priority transmissions.
69 Simple packet rate limiter added to online-related tools
70 (@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller}).
72 Ability to specify niceness with symbolic notation:
73 @verb{|NORMAL|}, @verb{|BULK+10|}, @verb{|PRIORITY-5|}, etc.
75 Changed default niceness levels:
76 for @command{nncp-exec} from 64 to 96,
77 for @command{nncp-freq} from 64 to 160,
78 for @command{nncp-file} from 196 to 224.
85 @strong{Incompatible} @emph{bundle} archive format changes and
86 @command{nncp-bundle} workability with Go 1.10+. Bundles must be
87 valid tar archives, but Go 1.9 made them invalid because of long paths
88 inside. NNCP accidentally was dependant on that bug. Explicit adding of
89 @file{NNCP/} directory in archive restores workability with valid tar
97 Ability to disable relaying at all using @verb{|-via -|} command line option.
104 @strong{Incompatible} plain packet format changes. Older versions are
107 Ability to queue remote command execution, by configuring @option{exec}
108 option in configuration file and using @command{nncp-exec} command:
111 @command{nncp-mail} command is replaced with more flexible
112 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
113 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
115 @option{sendmail} configuration file option is replaced with
116 @option{exec}. @verb{|sendmail: [...]|} must be replaced with
117 @verb{|exec: sendmail: [...]|}.
120 Ability to override @option{via} configuration option for destination
121 node via @option{-via} command line option for following commands:
122 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
124 Chunked files, having size less than specified chunk size, will be sent
125 as an ordinary single file.
127 Exec commands are invoked with additional @env{NNCP_NICE} and
128 @env{NNCP_SELF} environment variables.
130 Files, that are sent as a reply to freq, have niceness level taken from
131 the freq packet. You can set desired niceness during @command{nncp-freq}
132 invocation using @option{-replynice} option.
134 @command{nncp-toss} command can ignore specified packet types during
135 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
138 @command{nncp-file} command uses
139 @option{FreqMinSize}/@option{FreqChunked} configuration file options
140 for @option{-minsize}/@option{-chunked} by default. You can turn this
141 off by specifying zero value.
148 @strong{Incompatible} encrypted/eblob packet format changes. Older
149 versions are not supported.
151 Twofish encryption algorithm is replaced with ChaCha20. It is much more
152 faster. One cryptographic primitive less.
154 HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
155 another cryptographic primitive less (assuming that BLAKE2X is nearly
156 identical to BLAKE2).
163 @strong{Incompatible} encrypted packet format changes. Older versions
166 @command{nncp-bundle} command can either create stream of encrypted
167 packets, or digest it. It is useful when dealing with stdin/stdout based
168 transmission methods (like writing to CD-ROM without intermediate
169 prepared ISO image and working with tape drives).
171 @command{nncp-toss} is able to create @file{.seen} files preventing
172 duplicate packets receiving.
174 Single background checksum verifier worker is allowed in
175 @command{nncp-call}. This is helpful when thousands of small inbound
176 packets could create many goroutines.
178 Ability to override path to spool directory and logfile through either
179 command line argument, or environment variable.
181 @command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
182 @file{.part}, @file{.lock} and temporary files.
186 @section Release 0.12
189 Sendmail command is called with @env{NNCP_SENDER} environment variable.
193 @section Release 0.11
196 @command{nncp-stat}'s command output is sorted by node name.
200 @section Release 0.10
203 @command{nncp-freq}'s @file{DST} argument is optional now. Last
204 @file{SRC} path's element will be used by default.
211 Fix @option{-rx}/@option{-tx} arguments processing in
212 @command{nncp-call} command. They were ignored.
219 Little bugfix in @command{nncp-file} command, where @option{-minsize}
220 option for unchunked transfer was not in KiBs, but in bytes.
227 Ability to feed @command{nncp-file} from stdin, that uses an encrypted
228 temporary file for that.
231 Chunked files transmission appeared with corresponding
232 @command{nncp-reass} command and @option{freqchunked} configuration file
233 entry. Useful for transferring big files over small storage devices.
236 @option{freqminsize} configuration file option, analogue to
237 @option{-minsize} one.
240 @command{nncp-xfer}'s @option{-force} option is renamed to
241 @option{-mkdir} for clarity.
244 @option{-minsize} option is specified in KiBs, not bytes, for
248 @command{nncp-newcfg} command is renamed to @command{nncp-cfgnew},
249 and @command{nncp-mincfg} to @command{nncp-cfgmin} -- now they have
250 common prefix and are grouped together for convenience.
253 @command{nncp-cfgenc} command appeared, allowing configuration file
254 encryption/decryption, for keeping it safe without any either OpenPGP or
258 Cryptographic libraries (dependencies) are updated.
264 @item Small @command{nncp-rm} command appeared.
265 @item Cryptographic libraries (dependencies) are updated.
271 @item Trivial small fix in default niceness level of @command{nncp-file}
272 and @command{nncp-freq} commands.
278 @item Small fix in @command{nncp-call}, @command{nncp-caller},
279 @command{nncp-daemon}: they can segmentation fail sometimes (no data is
281 @item @command{nncp-newnode} renamed to @command{nncp-newcfg} -- it is
282 shorter and more convenient to use.
283 @item @command{nncp-mincfg} command appeared: helper allowing to create
284 minimalistic stripped down configuration file without private keys,
285 that is useful during @command{nncp-xfer} usage.
290 Fixed compatibility with Go 1.6.
295 @item @strong{Incompatible} packet's format change (magic number is
296 changed too): size field is encrypted and is not send in plaintext
298 @item @option{-minsize} option gives ability to automatically pad
299 outgoing packets to specified minimal size.
300 @item @command{nncp-daemon} and
301 @command{nncp-call}/@command{nncp-caller} always check new @emph{tx}
302 packets appearance in the background while connected. Remote side is
303 immediately notified.
304 @item @option{-onlinedeadline} option gives ability to configure timeout
305 of inactivity of online connection, when it could be disconnected. It
306 could be used to keep connection alive for a long time.
307 @item @option{-maxonlinetime} option gives ability to set maximal
308 allowable online connection aliveness time.
309 @item @command{nncp-caller} command appeared: cron-ed TCP daemon caller.
310 @item @command{nncp-pkt} command can decompress the data.
