3 | TODO: bridge mode, finally? |
|
|
4 | |
|
|
5 | - INCOMPATIBLE CHANGE: no longer enable udp protocol if no other |
|
|
6 | protocols are enabled - this is necessary when you have nodes with |
|
|
7 | completely unknown protocols, to force mediated connection requests. |
|
|
8 | - INCOMPATIBLE CHANGE: dns transport protocol bumped to version 2. |
|
|
9 | - switch to using RSA_generate_key_ex, which is the undocumented |
|
|
10 | and needlessly more complicated replacement for the RSA_generate_key |
|
|
11 | function which is now deprecated. |
|
|
12 | - change public exponent for rsa keys from 65535 to 65537, for |
|
|
13 | efficiency reasons. |
|
|
14 | - nodes would sometimes declare transport endpoints valid despite |
|
|
15 | the protocol not being configured locally. |
|
|
16 | - core protocol version 0.1, compatible with older releases. |
|
|
17 | - new global configuration options: chroot, chuser, chuid, chgid, |
|
|
18 | to chroot to a specified or anonymous new root, and change user id. |
|
|
19 | - prefer inet_aton over gethostbyname, as the latter is not guaranteed |
|
|
20 | to "resolve" literal ip addresses. |
|
|
21 | - configure didn't detect openssl 1.0 because SHA1_version became private |
|
|
22 | (patch by TANIGUCHI Takaki). |
|
|
23 | - fix a bug where nodes would tell the other side that it supports |
|
|
24 | the same protocols as that other side, instead of its own. |
|
|
25 | - add zlib when found, as openssl depends on it in newer versions. |
|
|
26 | - work around append-bugs in uclibc by using an extra seek. |
|
|
27 | - new "include" directive for the config file. |
|
|
28 | - gvpectrl no longer evaluates any "on" directives. |
|
|
29 | - icmp and rawip protocols weren't upgradable to each other. |
|
|
30 | - major, but incremental, dns transport improvements: |
|
|
31 | - do not simply abort in some error cases in the dns transport, |
|
|
32 | but try to recover. |
|
|
33 | - allow lowercase/uppercase alises for base-n encodings that do |
|
|
34 | not rely on case. |
|
|
35 | - use base26 instead of base22 encoding for dns syn's, and |
|
|
36 | base36 instead of base22 for headers (saves one byte/packet). |
|
|
37 | - back off far quicker in dns tunnel when idling - increases |
|
|
38 | latency on an idle link somewhat, but avoids hundreds of |
|
|
39 | needless packets. |
|
|
40 | - poll more aggressively when idling in dns (poll once per |
|
|
41 | second as opposed to once per 5 seconds). |
|
|
42 | - reduce dns send payload size to allow greater rate of ack |
|
|
43 | messages (should help sack and ipv6). |
|
|
44 | - allow for ip options in rawip/icmp transports, even though gvpe |
|
|
45 | doesn't generate them. |
|
|
46 | - upgrade to libev 4 API. |
|
|
47 | |
|
|
48 | 2.24 Sat Feb 12 05:15:48 CET 2011 |
|
|
49 | - protocol version 0.1, compatible with older releases. |
|
|
50 | - due to a bug, when packets were lost, a connection could go into a |
|
|
51 | state where a ping/connection request from another node would be |
|
|
52 | ignored, leading to connections not being re-established. |
|
|
53 | - due to a bug, compression was almost always enabled. |
|
|
54 | - enable-max-mtu was actually enable-mtu, contrary to documentation. |
|
|
55 | - add nfmark support. |
|
|
56 | - add node-change script support. |
|
|
57 | - new DESTSI variable for node-xxx scripts. |
|
|
58 | - updated codingstyle a bit, declared truly static stuff as static. |
|
|
59 | - clarify compression docs. |
|
|
60 | |
|
|
61 | 2.22 Sun Feb 1 17:25:28 CET 2009 |
|
|
62 | - protocol version 0.1, compatible with older releases. |
|
|
63 | - enabled icmp/tcp/http-proxy protocols by default. |
|
|
64 | - updated copyright in program greetings. |
|
|
65 | - fix some configure messages. |
|
|
66 | - updated to libev 3.52. |
|
|
67 | |
|
|
68 | 2.21 Wed Sep 3 06:56:27 CEST 2008 |
|
|
69 | - protocol version 0.1, compatible with older releases. |
|
|
70 | - add missing ev++.h include header to tarball, which everybody |
|
|
71 | who tested it apparently had in their include path :(. Caught |
|
|
72 | by Karl Kleinpaste and Marcus Kong. |
|
|
73 | |
|
|
74 | 2.2 Mon Sep 1 06:28:09 CEST 2008 |
|
|
75 | - protocol version 0.1, compatible with older releases. |
|
|
76 | but upgrade is recommended to due changed ondemand behaviour. |
|
|
77 | - new per-node options max-ttl and max-queue. |
|
|
78 | - convert from iom.C to libev, a high-performance event loop |
|
|
79 | (http://software.schmorp.de/pkg/libev). |
|
|
80 | - tcp connections were leaking in some cases. |
|
|
81 | - retry more aggressively (once/s) to establish a connection if |
|
|
82 | new packets arrive for it. |
|
|
83 | - save a lot of setsockopt calls when the tos doesn't change. |
|
|
84 | - honor disabled even on initial connect attempt. |
|
|
85 | - changed callback mechanism to be slightly less portable |
|
|
86 | but more efficient mechanism (standards-compliant c++ compilers |
|
|
87 | should work). |
|
|
88 | - increased receive window positive size, to allow for massive |
|
|
89 | packet loss due to occasional longer drop-outs. |
|
|
90 | - send RST when a positive window size violation is detected, but |
|
|
91 | not in other cases, to reconnect more quickly. |
|
|
92 | - upgraded liblzf to version 3.4. |
|
|
93 | - dropped -fno-exceptions due to ev++.h using it. |
|
|
94 | - node-up/down scripts are now run in sequence. |
|
|
95 | - new -q switch for gvpectrl, for when you run it often. |
|
|
96 | - work around the horribly inconsistent, ad-hoc, ever-changing |
|
|
97 | and broken texinfo syntax. YMMV. avoid texinfo. |
|
|
98 | - keepalive is more aggressive now, sensding ping's every 3 seconds |
|
|
99 | and killing the conenction after 15 seconds. |
|
|
100 | - bugfixes. |
|
|
101 | |
|
|
102 | 2.01 Thu Mar 29 19:26:04 CEST 2007 |
|
|
103 | - protocol version 0.1, compatible with older releases. |
|
|
104 | - bugfix of callback.h, might have cause callback return values to |
|
|
105 | be corrupted on architectures like sparc before. |
|
|
106 | - dns transport retries more aggressively. |
|
|
107 | - updated documentation, improved dns transport reliability |
|
|
108 | and throughput. |
|
|
109 | - added experimental support for sha256 and sha512 digests. |
|
|
110 | |
|
|
111 | 2.0 Mon Dec 5 13:59:26 CET 2005 |
|
|
112 | - protocol version 0.1, compatible with older releases. |
|
|
113 | - implement allow-direct, deny-direct node config statements. |
|
|
114 | - implemented != for sockinfo. This fixes a bug where |
|
|
115 | gvpe sent packets to the old ip address of another host |
|
|
116 | even though it had received packets from it's new address. |
|
|
117 | This only causes problems if you forget to -HUP your gvpe after |
|
|
118 | your ip address changed, which is *required*. |
|
|
119 | - sets close-on-exec flag on tcp connections. This fixes a bug |
|
|
120 | where child processes kept tcp connections open and caused |
|
|
121 | connections to fail when only one side can connect. |
|
|
122 | - fixed a bug in receive sequence checking that made gvpe |
|
|
123 | accept out-of-window packets in most cases. |
|
|
124 | - tighter limit for the maximum sequence # to avoid overflow |
|
|
125 | conditions + allow more headroom for packet reordering. |
|
|
126 | - replace some asserts that trapped config mismatches by |
|
|
127 | more useful log messages. |
|
|
128 | - fix spurious extra newline in some log messages. |
|
|
129 | |
|
|
130 | 1.9 Tue Apr 19 06:21:50 CEST 2005 |
|
|
131 | - protocol version 0.1, compatible with older releases. |
|
|
132 | - WARNING: this version checks the return value of if-up etc. |
|
|
133 | scripts and exits on failure. |
|
|
134 | - IMPORTANT: run if-up/node-up etc. scripts via /bin/sh. |
|
|
135 | - IMPORTANT: interface initialization (MAC, MTU) is now done |
|
|
136 | automatically in most configurations. |
|
|
137 | - options can now be specified on the gvpe command line, too. |
|
|
138 | - make some DNS transport values configurable and document them. |
|
|
139 | - improved OS specific information in gvpe.osdep(5). |
|
|
140 | - new tap device type "native/darwin", that supports the tap |
|
|
141 | driver available for darwin (thanks to matthew mead who tested |
|
|
142 | it out with me in a long session). tincd/darwin is still available. |
|
|
143 | - new device type "tincd/bsd", which is a newer version of the |
|
|
144 | *bsd-drivers taken from tinc. |
|
|
145 | - fixed a bug in relying on the order of global construction |
|
|
146 | when tcp transport was enabled. The fix makes it use no |
|
|
147 | cpu time unless it is in use, too. |
|
|
148 | - information about other nodes is now available to if-up etc. scripts. |
|
|
149 | - the value of the config variable if-up-data is passed to the if-up |
|
|
150 | etc. scripts. |
| 1 | - skip unparsable config lines instead of stopping parsing. |
151 | - skip unparsable config lines with a warning instead of stopping |
|
|
152 | parsing and continuing with a certainly unusable config. |

| 3 | 1.8 Fri Mar 18 00:58:55 CET 2005 |
154 | 1.8 Fri Mar 18 00:58:55 CET 2005 |
|
|
155 | - protocol version 0.1, compatible with older releases. |
| 4 | - enable-udp = yes is now default only when no other protocols |
156 | - enable-udp = yes is now default only when no other protocols |
| 5 | are enabled. otherwise it is disabled unless explicitly enabled. |
157 | are enabled. otherwise it is disabled unless explicitly enabled. |
| 6 | - implemented dns tunneling (experimental now and in the future). |
158 | - implemented dns tunneling (experimental now and in the future). |
| 7 | - remove support for pre-release version protocol. |
159 | - remove support for pre-release version protocol. |
| 8 | - updated tincd drivers (rev 1433), added uml_socket driver, documented |
