3 root 1.106 New option OPENSSL_NO_SSL_INTERN. If an application can be compiled
4     with this defined it will not be affected by any changes to ssl internal
5     structures. Add several utility functions to allow openssl application
6     to work with OPENSSL_NO_SSL_INTERN defined.
7     [Steve Henson]
8     TODO: bridge mode, finally?
9    
10 root 1.97 - INCOMPATIBLE CHANGE: no longer enable udp protocol if no other
11     protocols are enabled - this is necessary when you have nodes with
12     completely unknown protocols, to force mediated connection requests.
13 root 1.99 - INCOMPATIBLE CHANGE: dns transport protocol bumped to version 2.
14 root 1.105 - nodes would sometimes declare transport endpoints valid despite
15     the protocol not being configured locally.
16 root 1.106 - new global configuration options: chroot, chuser, chuid, chgid,
17     to chroot to a specified or anonymous new root, and change user id.
18 root 1.102 - configure didn't detect openssl 1.0 because SHA1_version became private
19     (patch by TANIGUCHI Takaki).
20 root 1.99 - core protocol version 0.1, compatible with older releases.
21 root 1.97 - fix a bug where nodes would tell the other side that it supports
22     the same protocols as that other side, instead of its own.
23 root 1.98 - add zlib when found, as openssl depends on it in newer versions.
24     - work around append-bugs in uclibc by using an extra seek.
25 root 1.99 - new "include" directive for the config file.
26 root 1.100 - gvpectrl no longer evaluates any "on" directives.
27 root 1.102 - icmp and rawip protocols weren't upgradable to each other.
28 root 1.99 - major, but incremental, dns transport improvements:
29     - do not simply abort in some error cases in the dns transport,
30     but try to recover.
31     - allow lowercase/uppercase alises for base-n encodings that do
32     not rely on case.
33     - use base26 instead of base22 encoding for dns syn's, and
34     base36 instead of base22 for headers (saves one byte/packet).
35     - back off far quicker in dns tunnel when idling - increases
36     latency on an idle link somewhat, but avoids hundreds of
37     needless packets.
38     - poll more aggressively when idling in dns (poll once per
39     second as opposed to once per 5 seconds).
40 root 1.104 - reduce dns send payload size to allow greater rate of ack
41     messages (should help sack and ipv6).
42 root 1.103 - allow for ip options in rawip/icmp transports, even though gvpe
43     doesn't generate them.
44 root 1.101 - upgrade to libev 4 API.
45 root 1.97
46     2.24 Sat Feb 12 05:15:48 CET 2011
47     - protocol version 0.1, compatible with older releases.
48 root 1.95 - due to a bug, when packets were lost, a connection could go into a
49 root 1.94 state where a ping/connection request from another node would be
50 root 1.96 ignored, leading to connections not being re-established.
51 pcg 1.93 - due to a bug, compression was almost always enabled.
52 pcg 1.92 - enable-max-mtu was actually enable-mtu, contrary to documentation.
53 pcg 1.90 - add nfmark support.
54 pcg 1.91 - add node-change script support.
55     - new DESTSI variable for node-xxx scripts.
56 root 1.95 - updated codingstyle a bit, declared truly static stuff as static.
57 root 1.96 - clarify compression docs.
58 pcg 1.90
59 pcg 1.89 2.22 Sun Feb 1 17:25:28 CET 2009
60 root 1.97 - protocol version 0.1, compatible with older releases.
61 pcg 1.86 - enabled icmp/tcp/http-proxy protocols by default.
62 pcg 1.85 - updated copyright in program greetings.
63 pcg 1.86 - fix some configure messages.
64 pcg 1.87 - updated to libev 3.52.
65 pcg 1.85
66 pcg 1.84 2.21 Wed Sep 3 06:56:27 CEST 2008
67 root 1.97 - protocol version 0.1, compatible with older releases.
68 pcg 1.84 - add missing ev++.h include header to tarball, which everybody
69     who tested it apparently had in their include path :(. Caught
70 pcg 1.85 by Karl Kleinpaste and Marcus Kong.
71 pcg 1.84
72 pcg 1.83 2.2 Mon Sep 1 06:28:09 CEST 2008
73 root 1.97 - protocol version 0.1, compatible with older releases.
74 pcg 1.78 but upgrade is recommended to due changed ondemand behaviour.
75     - new per-node options max-ttl and max-queue.
76 pcg 1.72 - convert from iom.C to libev, a high-performance event loop
77 pcg 1.71 (http://software.schmorp.de/pkg/libev).
78 pcg 1.73 - tcp connections were leaking in some cases.
79 pcg 1.78 - retry more aggressively (once/s) to establish a connection if
80     new packets arrive for it.
81 pcg 1.75 - save a lot of setsockopt calls when the tos doesn't change.
82 pcg 1.78 - honor disabled even on initial connect attempt.
83 pcg 1.76 - changed callback mechanism to be slightly less portable
84     but more efficient mechanism (standards-compliant c++ compilers
85     should work).
86 pcg 1.80 - increased receive window positive size, to allow for massive
87     packet loss due to occasional longer drop-outs.
88     - send RST when a positive window size violation is detected, but
89     not in other cases, to reconnect more quickly.
90 pcg 1.83 - upgraded liblzf to version 3.4.
91 pcg 1.77 - dropped -fno-exceptions due to ev++.h using it.
92 pcg 1.81 - node-up/down scripts are now run in sequence.
93     - new -q switch for gvpectrl, for when you run it often.
94 pcg 1.82 - work around the horribly inconsistent, ad-hoc, ever-changing
95     and broken texinfo syntax. YMMV. avoid texinfo.
96 pcg 1.83 - keepalive is more aggressive now, sensding ping's every 3 seconds
97     and killing the conenction after 15 seconds.
98 pcg 1.71 - bugfixes.
99    
100 pcg 1.70 2.01 Thu Mar 29 19:26:04 CEST 2007
101 pcg 1.69 - protocol version 0.1, compatible with older releases.
102 pcg 1.68 - bugfix of callback.h, might have cause callback return values to
103     be corrupted on architectures like sparc before.
104 pcg 1.69 - dns transport retries more aggressively.
105 pcg 1.70 - updated documentation, improved dns transport reliability
106     and throughput.
107     - added experimental support for sha256 and sha512 digests.
108 pcg 1.67
109 pcg 1.66 2.0 Mon Dec 5 13:59:26 CET 2005
110 pcg 1.56 - protocol version 0.1, compatible with older releases.
111 pcg 1.65 - implement allow-direct, deny-direct node config statements.
112 pcg 1.59 - implemented != for sockinfo. This fixes a bug where
113     gvpe sent packets to the old ip address of another host
114     even though it had received packets from it's new address.
115 pcg 1.61 This only causes problems if you forget to -HUP your gvpe after
116 pcg 1.59 your ip address changed, which is *required*.
117 pcg 1.64 - sets close-on-exec flag on tcp connections. This fixes a bug
118     where child processes kept tcp connections open and caused
119     connections to fail when only one side can connect.
120     - fixed a bug in receive sequence checking that made gvpe
121     accept out-of-window packets in most cases.
122 pcg 1.61 - tighter limit for the maximum sequence # to avoid overflow
123     conditions + allow more headroom for packet reordering.
124 pcg 1.66 - replace some asserts that trapped config mismatches by
125 pcg 1.62 more useful log messages.
126 pcg 1.63 - fix spurious extra newline in some log messages.
127 pcg 1.56
128 pcg 1.55 1.9 Tue Apr 19 06:21:50 CEST 2005
129 pcg 1.56 - protocol version 0.1, compatible with older releases.
130 pcg 1.49 - WARNING: this version checks the return value of if-up etc.
131     scripts and exits on failure.
132 pcg 1.50 - IMPORTANT: run if-up/node-up etc. scripts via /bin/sh.
133     - IMPORTANT: interface initialization (MAC, MTU) is now done
134     automatically in most configurations.
135 pcg 1.54 - options can now be specified on the gvpe command line, too.
136 pcg 1.49 - make some DNS transport values configurable and document them.
137     - improved OS specific information in gvpe.osdep(5).
138 pcg 1.51 - new tap device type "native/darwin", that supports the tap
139 pcg 1.45 driver available for darwin (thanks to matthew mead who tested
140 pcg 1.47 it out with me in a long session). tincd/darwin is still available.
141 pcg 1.51 - new device type "tincd/bsd", which is a newer version of the
142     *bsd-drivers taken from tinc.
143 pcg 1.46 - fixed a bug in relying on the order of global construction
144     when tcp transport was enabled. The fix makes it use no
145     cpu time unless it is in use, too.
146 pcg 1.52 - information about other nodes is now available to if-up etc. scripts.
147     - the value of the config variable if-up-data is passed to the if-up
148     etc. scripts.
149 pcg 1.49 - skip unparsable config lines with a warning instead of stopping
150     parsing and continuing with a certainly unusable config.
151 pcg 1.43
152 pcg 1.41 1.8 Fri Mar 18 00:58:55 CET 2005
153 pcg 1.56 - protocol version 0.1, compatible with older releases.
154 pcg 1.36 - enable-udp = yes is now default only when no other protocols
155     are enabled. otherwise it is disabled unless explicitly enabled.
156 pcg 1.40 - implemented dns tunneling (experimental now and in the future).
157 pcg 1.39 - remove support for pre-release version protocol.
158 pcg 1.41 - updated tincd drivers (rev 1433), added uml_socket driver, documented
159     tincd drivers a bit better.
160 pcg 1.40 - document icmp configuration values.
161     - document transport protocols in gvpe.protocol(7).
162     - remove unused ChangeLog file.
163 pcg 1.41 - created a mailinglist at gvpe@lists.schmorp.de.
164     - added an exemption to allow distribution of binaries linked against
165     OpenSSL, as suggested by Guus Sliepen (author of tinc). No
166     GNUTLS conversion in sight.
167 pcg 1.42 - some portability fixes with respect to --disable-nls.
168 pcg 1.36
169 pcg 1.35 1.7 Tue Feb 22 23:58:59 CET 2005
170 pcg 1.32 - protocol version 0.1, compatible with older releases.
171 pcg 1.26 - first gnu release.
172 pcg 1.27 - documented the special value 1 for router-priority.
173 pcg 1.26 - renamed vped => gvpe and vpectrl => gvpectrl, as well as
174     vped.conf => gvpe.conf.
175 pcg 1.29 - new per-node option "max-retry".
176 pcg 1.22 - asymmetric rekeying behaviour, so hosts don't rekey simultaneously.
177 pcg 1.24 - new configure option --enable-static-daemon.
178 pcg 1.23 - fix configure --help output.
179 pcg 1.26 - many documentation layout fixes.
180 pcg 1.28 - synced iom.[Ch] from rxvt-unicode.
181 pcg 1.34 - try to cope with some non-monotonic time changes.
182 pcg 1.30 - revert to locale.h - a usual, clocale is nonfunctioning on macosx.
183 pcg 1.32 - considerably improved pod2texi and the resulting texi doc.
184 pcg 1.22
185 pcg 1.21 1.6.1 Wed May 12 14:48:20 CEST 2004
186 pcg 1.32 - protocol version 0.1, compatible with older releases.
187 pcg 1.22 - fix -c switch that has been broken due to a last-minute fix
188     to option and config file parsing.
189 pcg 1.21
190 pcg 1.20 1.6 Mon May 10 20:55:10 CEST 2004
191 pcg 1.22 - protocol version 0.1, compatible with older releases.
192     - do not RESET on out-of-sequence packets (good for wireless).
193     - various non-security-related bugfixes.
194     - c++ify (at least make it compile with g++-3.4, which should make
195     it a little bit more standard c++).
196 pcg 1.19
197 pcg 1.18 1.5 Fri Jan 30 00:50:04 CET 2004
198 pcg 1.22 - protocol version 0.1, compatible with older releases.
199     - vped will refuse to start when hostkey and public key do not match.
200     - updated lzf code to version 1.2.
201     - better error reporting for "unusual" conditions, like failing
202     to allocate memory, that should not normally happen and
203     will otherwise result in spurious other error messages. Also
204     adds paranoid checks in case openssl's API changes in a bad way.
205     - fix a bug where queued vpn packets were cleared to zero. while
206     this doesn't affect security, it did cause warning messages and
207     unnecessary connectivity delays.
208 pcg 1.15
209 pcg 1.13 1.4 Sat Jan 17 15:49:21 CET 2004
210 pcg 1.22 - protocol version 0.1, compatible with older releases.
211     - better retry behaviour on key mismatch.
212     - use select-based io_manager instead of poll-based one.
213     - share io manager between rxvt-unicode and vpe.
214     - sooo many *BSD workarounds because no BSD I could find is even
215     remotely POSIX-compatible.
216 pcg 1.11
217 pcg 1.10 1.2 Fri Oct 17 03:44:44 CEST 2003
218 pcg 1.22 - protocol version 0.1.
219     - tincd kernel interface code imported, more supported platforms
220     (native/linux (2.4), tincd/linux (2.2 and 2.4), tincd/freebsd,
221     native/cygwin).
222     - added primitive ethernet emulation (ipv4 only), which allows
223     the following platforms that only have tun drivers to work:
224     /* none yet tested */
225     - portability workarounds, especially for unfriendly freebsd
226     - very minor bugfixes
227     - warnings when choosing insecure ciphers/hashes
228     - reduced default hmac length to 8.
229     - cvs now contains configure, Makefile.in and other generated files.
230     - added doc/complex-example to the distribution.
231    
232     1.0 distant past
233     - protocol version 0.1.
234     - tweaked various timeouts to help very slow (486) class
235     machines or nets with many hosts.
236     - tweaked rate-limiting to be more forgiving for hosts
237     connecting through routers (not a fix).
238 pcg 1.2
