3 - INCOMPATIBLE CHANGE: no longer enable udp protocol if no other
4 protocols are enabled - this is necessary when you have nodes with
5 completely unknown protocols, to force mediated connection requests.
6 - INCOMPATIBLE CHANGE: dns transport protocol bumped to version 2.
7 - configure didn't detect openssl 1.0 because SHA1_version became private
8 (patch by TANIGUCHI Takaki).
9 - core protocol version 0.1, compatible with older releases.
10 - fix a bug where nodes would tell the other side that it supports
11 the same protocols as that other side, instead of its own.
12 - add zlib when found, as openssl depends on it in newer versions.
13 - work around append-bugs in uclibc by using an extra seek.
14 - new "include" directive for the config file.
15 - gvpectrl no longer evaluates any "on" directives.
16 - icmp and rawip protocols weren't upgradable to each other.
17 - major, but incremental, dns transport improvements:
18 - do not simply abort in some error cases in the dns transport,
19 but try to recover.
20 - allow lowercase/uppercase alises for base-n encodings that do
21 not rely on case.
22 - use base26 instead of base22 encoding for dns syn's, and
23 base36 instead of base22 for headers (saves one byte/packet).
24 - back off far quicker in dns tunnel when idling - increases
25 latency on an idle link somewhat, but avoids hundreds of
26 needless packets.
27 - poll more aggressively when idling in dns (poll once per
28 second as opposed to once per 5 seconds).
29 - reduce dns send payload size to allow greater rate of ack
30 messages (should help sack and ipv6).
31 - allow for ip options in rawip/icmp transports, even though gvpe
32 doesn't generate them.
33 - upgrade to libev 4 API.
34
35 2.24 Sat Feb 12 05:15:48 CET 2011
36 - protocol version 0.1, compatible with older releases.
37 - due to a bug, when packets were lost, a connection could go into a
38 state where a ping/connection request from another node would be
39 ignored, leading to connections not being re-established.
40 - due to a bug, compression was almost always enabled.
41 - enable-max-mtu was actually enable-mtu, contrary to documentation.
42 - add nfmark support.
43 - add node-change script support.
44 - new DESTSI variable for node-xxx scripts.
45 - updated codingstyle a bit, declared truly static stuff as static.
46 - clarify compression docs.
47
48 2.22 Sun Feb 1 17:25:28 CET 2009
49 - protocol version 0.1, compatible with older releases.
50 - enabled icmp/tcp/http-proxy protocols by default.
51 - updated copyright in program greetings.
52 - fix some configure messages.
53 - updated to libev 3.52.
54
55 2.21 Wed Sep 3 06:56:27 CEST 2008
56 - protocol version 0.1, compatible with older releases.
57 - add missing ev++.h include header to tarball, which everybody
58 who tested it apparently had in their include path :(. Caught
59 by Karl Kleinpaste and Marcus Kong.
60
61 2.2 Mon Sep 1 06:28:09 CEST 2008
62 - protocol version 0.1, compatible with older releases.
63 but upgrade is recommended to due changed ondemand behaviour.
64 - new per-node options max-ttl and max-queue.
65 - convert from iom.C to libev, a high-performance event loop
66 (http://software.schmorp.de/pkg/libev).
67 - tcp connections were leaking in some cases.
68 - retry more aggressively (once/s) to establish a connection if
69 new packets arrive for it.
70 - save a lot of setsockopt calls when the tos doesn't change.
71 - honor disabled even on initial connect attempt.
72 - changed callback mechanism to be slightly less portable
73 but more efficient mechanism (standards-compliant c++ compilers
74 should work).
75 - increased receive window positive size, to allow for massive
76 packet loss due to occasional longer drop-outs.
77 - send RST when a positive window size violation is detected, but
78 not in other cases, to reconnect more quickly.
79 - upgraded liblzf to version 3.4.
80 - dropped -fno-exceptions due to ev++.h using it.
81 - node-up/down scripts are now run in sequence.
82 - new -q switch for gvpectrl, for when you run it often.
83 - work around the horribly inconsistent, ad-hoc, ever-changing
84 and broken texinfo syntax. YMMV. avoid texinfo.
85 - keepalive is more aggressive now, sensding ping's every 3 seconds
86 and killing the conenction after 15 seconds.
87 - bugfixes.
88
89 2.01 Thu Mar 29 19:26:04 CEST 2007
90 - protocol version 0.1, compatible with older releases.
91 - bugfix of callback.h, might have cause callback return values to
92 be corrupted on architectures like sparc before.
93 - dns transport retries more aggressively.
94 - updated documentation, improved dns transport reliability
95 and throughput.
96 - added experimental support for sha256 and sha512 digests.
97
98 2.0 Mon Dec 5 13:59:26 CET 2005
99 - protocol version 0.1, compatible with older releases.
100 - implement allow-direct, deny-direct node config statements.
101 - implemented != for sockinfo. This fixes a bug where
102 gvpe sent packets to the old ip address of another host
103 even though it had received packets from it's new address.
104 This only causes problems if you forget to -HUP your gvpe after
105 your ip address changed, which is *required*.
106 - sets close-on-exec flag on tcp connections. This fixes a bug
107 where child processes kept tcp connections open and caused
108 connections to fail when only one side can connect.
109 - fixed a bug in receive sequence checking that made gvpe
110 accept out-of-window packets in most cases.
111 - tighter limit for the maximum sequence # to avoid overflow
112 conditions + allow more headroom for packet reordering.
113 - replace some asserts that trapped config mismatches by
114 more useful log messages.
115 - fix spurious extra newline in some log messages.
116
117 1.9 Tue Apr 19 06:21:50 CEST 2005
118 - protocol version 0.1, compatible with older releases.
119 - WARNING: this version checks the return value of if-up etc.
120 scripts and exits on failure.
121 - IMPORTANT: run if-up/node-up etc. scripts via /bin/sh.
122 - IMPORTANT: interface initialization (MAC, MTU) is now done
123 automatically in most configurations.
124 - options can now be specified on the gvpe command line, too.
125 - make some DNS transport values configurable and document them.
126 - improved OS specific information in gvpe.osdep(5).
127 - new tap device type "native/darwin", that supports the tap
128 driver available for darwin (thanks to matthew mead who tested
129 it out with me in a long session). tincd/darwin is still available.
130 - new device type "tincd/bsd", which is a newer version of the
131 *bsd-drivers taken from tinc.
132 - fixed a bug in relying on the order of global construction
133 when tcp transport was enabled. The fix makes it use no
134 cpu time unless it is in use, too.
135 - information about other nodes is now available to if-up etc. scripts.
136 - the value of the config variable if-up-data is passed to the if-up
137 etc. scripts.
138 - skip unparsable config lines with a warning instead of stopping
139 parsing and continuing with a certainly unusable config.
140
141 1.8 Fri Mar 18 00:58:55 CET 2005
142 - protocol version 0.1, compatible with older releases.
143 - enable-udp = yes is now default only when no other protocols
144 are enabled. otherwise it is disabled unless explicitly enabled.
145 - implemented dns tunneling (experimental now and in the future).
146 - remove support for pre-release version protocol.
147 - updated tincd drivers (rev 1433), added uml_socket driver, documented
148 tincd drivers a bit better.
149 - document icmp configuration values.
150 - document transport protocols in gvpe.protocol(7).
151 - remove unused ChangeLog file.
152 - created a mailinglist at gvpe@lists.schmorp.de.
153 - added an exemption to allow distribution of binaries linked against
154 OpenSSL, as suggested by Guus Sliepen (author of tinc). No
155 GNUTLS conversion in sight.
156 - some portability fixes with respect to --disable-nls.
157
158 1.7 Tue Feb 22 23:58:59 CET 2005
159 - protocol version 0.1, compatible with older releases.
160 - first gnu release.
161 - documented the special value 1 for router-priority.
162 - renamed vped => gvpe and vpectrl => gvpectrl, as well as
163 vped.conf => gvpe.conf.
164 - new per-node option "max-retry".
165 - asymmetric rekeying behaviour, so hosts don't rekey simultaneously.
166 - new configure option --enable-static-daemon.
167 - fix configure --help output.
168 - many documentation layout fixes.
169 - synced iom.[Ch] from rxvt-unicode.
170 - try to cope with some non-monotonic time changes.
171 - revert to locale.h - a usual, clocale is nonfunctioning on macosx.
172 - considerably improved pod2texi and the resulting texi doc.
173
174 1.6.1 Wed May 12 14:48:20 CEST 2004
175 - protocol version 0.1, compatible with older releases.
176 - fix -c switch that has been broken due to a last-minute fix
177 to option and config file parsing.
178
179 1.6 Mon May 10 20:55:10 CEST 2004
180 - protocol version 0.1, compatible with older releases.
181 - do not RESET on out-of-sequence packets (good for wireless).
182 - various non-security-related bugfixes.
183 - c++ify (at least make it compile with g++-3.4, which should make
184 it a little bit more standard c++).
185
186 1.5 Fri Jan 30 00:50:04 CET 2004
187 - protocol version 0.1, compatible with older releases.
188 - vped will refuse to start when hostkey and public key do not match.
189 - updated lzf code to version 1.2.
190 - better error reporting for "unusual" conditions, like failing
191 to allocate memory, that should not normally happen and
192 will otherwise result in spurious other error messages. Also
193 adds paranoid checks in case openssl's API changes in a bad way.
194 - fix a bug where queued vpn packets were cleared to zero. while
195 this doesn't affect security, it did cause warning messages and
196 unnecessary connectivity delays.
197
198 1.4 Sat Jan 17 15:49:21 CET 2004
199 - protocol version 0.1, compatible with older releases.
200 - better retry behaviour on key mismatch.
201 - use select-based io_manager instead of poll-based one.
202 - share io manager between rxvt-unicode and vpe.
203 - sooo many *BSD workarounds because no BSD I could find is even
204 remotely POSIX-compatible.
205
206 1.2 Fri Oct 17 03:44:44 CEST 2003
207 - protocol version 0.1.
208 - tincd kernel interface code imported, more supported platforms
209 (native/linux (2.4), tincd/linux (2.2 and 2.4), tincd/freebsd,
210 native/cygwin).
211 - added primitive ethernet emulation (ipv4 only), which allows
212 the following platforms that only have tun drivers to work:
213 /* none yet tested */
214 - portability workarounds, especially for unfriendly freebsd
215 - very minor bugfixes
216 - warnings when choosing insecure ciphers/hashes
217 - reduced default hmac length to 8.
218 - cvs now contains configure, Makefile.in and other generated files.
219 - added doc/complex-example to the distribution.
220
221 1.0 distant past
222 - protocol version 0.1.
223 - tweaked various timeouts to help very slow (486) class
224 machines or nets with many hosts.
225 - tweaked rate-limiting to be more forgiving for hosts
226 connecting through routers (not a fix).
