|
8 | - INCOMPATIBLE CHANGE: no longer enable udp protocol if no other |
|
|
9 | protocols are enabled - this is necessary when you have nodes with |
|
|
10 | completely unknown protocols, to force mediated connection requests. |
|
|
11 | - INCOMPATIBLE CHANGE: dns transport protocol bumped to version 2. |
| 5 | - protocol version 0.1, compatible with older releases. |
12 | - core protocol version 0.1, compatible with older releases. |
|
|
13 | - switch to using RSA_generate_key_ex, which is the badly documented |
|
|
14 | and needlessly more complicated replacement for the RSA_generate_key |
|
|
15 | function which is now deprecated. |
|
|
16 | - support additional hmac hashes: sha256 and sha512, usually truncated. |
|
|
17 | - change public exponent for rsa keys from 65535 to 65537, for |
|
|
18 | efficiency reasons - only affects new keys. |
|
|
19 | - nodes would sometimes declare transport endpoints valid despite |
|
|
20 | the protocol not being configured locally. |
|
|
21 | - new global configuration options: chroot, chuser, chuid, chgid, |
|
|
22 | to chroot to a specified or anonymous new root, and change user id. |
|
|
23 | - new global configuration options seed_device and seed_interval, |
|
|
24 | to configure another device than /dev/urandom for random seeds, |
|
|
25 | and to configure a regular imterval to reseed the rng. |
|
|
26 | - prefer inet_aton over gethostbyname, as the latter is not guaranteed |
|
|
27 | to "resolve" literal ip addresses. |
|
|
28 | - configure didn't detect openssl 1.0 because SHA1_version became private |
|
|
29 | (patch by TANIGUCHI Takaki). |
|
|
30 | - fix a bug where nodes would tell the other side that it supports |
|
|
31 | the same protocols as that other side, instead of its own. |
|
|
32 | - add zlib when found, as openssl depends on it in newer versions. |
|
|
33 | - work around append-bugs in uclibc by using an extra seek. |
|
|
34 | - new "include" directive for the config file. |
|
|
35 | - gvpectrl no longer evaluates any "on" directives. |
|
|
36 | - icmp and rawip protocols weren't upgradable to each other. |
|
|
37 | - major, but incremental, dns transport improvements: |
|
|
38 | - do not simply abort in some error cases in the dns transport, |
|
|
39 | but try to recover. |
|
|
40 | - allow lowercase/uppercase alises for base-n encodings that do |
|
|
41 | not rely on case. |
|
|
42 | - use base26 instead of base22 encoding for dns syn's, and |
|
|
43 | base36 instead of base22 for headers (saves one byte/packet). |
|
|
44 | - back off far quicker in dns tunnel when idling - increases |
|
|
45 | latency on an idle link somewhat, but avoids hundreds of |
|
|
46 | needless packets. |
|
|
47 | - poll more aggressively when idling in dns (poll once per |
|
|
48 | second as opposed to once per 5 seconds). |
|
|
49 | - reduce dns send payload size to allow greater rate of ack |
|
|
50 | messages (should help sack and ipv6). |
|
|
51 | - allow for ip options in rawip/icmp transports, even though gvpe |
|
|
52 | doesn't generate them. |
|
|
53 | - upgrade to libev 4 API. |
|
|
54 | |
|
|
55 | 2.24 Sat Feb 12 05:15:48 CET 2011 |
|
|
56 | - protocol version 0.1, compatible with older releases. |
|
|
57 | - due to a bug, when packets were lost, a connection could go into a |
|
|
58 | state where a ping/connection request from another node would be |
|
|
59 | ignored, leading to connections not being re-established. |
|
|
60 | - due to a bug, compression was almost always enabled. |
|
|
61 | - enable-max-mtu was actually enable-mtu, contrary to documentation. |
|
|
62 | - add nfmark support. |
|
|
63 | - add node-change script support. |
|
|
64 | - new DESTSI variable for node-xxx scripts. |
|
|
65 | - updated codingstyle a bit, declared truly static stuff as static. |
|
|
66 | - clarify compression docs. |
|
|
67 | |
|
|
68 | 2.22 Sun Feb 1 17:25:28 CET 2009 |
|
|
69 | - protocol version 0.1, compatible with older releases. |
|
|
70 | - enabled icmp/tcp/http-proxy protocols by default. |
|
|
71 | - updated copyright in program greetings. |
|
|
72 | - fix some configure messages. |
|
|
73 | - updated to libev 3.52. |
|
|
74 | |
|
|
75 | 2.21 Wed Sep 3 06:56:27 CEST 2008 |
|
|
76 | - protocol version 0.1, compatible with older releases. |
|
|
77 | - add missing ev++.h include header to tarball, which everybody |
|
|
78 | who tested it apparently had in their include path :(. Caught |
|
|
79 | by Karl Kleinpaste and Marcus Kong. |
|
|

|
|
81 | 2.2 Mon Sep 1 06:28:09 CEST 2008 |
|
|
82 | - protocol version 0.1, compatible with older releases. |
|
|
83 | but upgrade is recommended to due changed ondemand behaviour. |
|
|
84 | - new per-node options max-ttl and max-queue. |
|
|
85 | - convert from iom.C to libev, a high-performance event loop |
|
|
86 | (http://software.schmorp.de/pkg/libev). |
|
|
87 | - tcp connections were leaking in some cases. |
|
|
88 | - retry more aggressively (once/s) to establish a connection if |
|
|
89 | new packets arrive for it. |
|
|
90 | - save a lot of setsockopt calls when the tos doesn't change. |
|
|
91 | - honor disabled even on initial connect attempt. |
|
|
92 | - changed callback mechanism to be slightly less portable |
|
|
93 | but more efficient mechanism (standards-compliant c++ compilers |
|
|
94 | should work). |
|
|
95 | - increased receive window positive size, to allow for massive |
|
|
96 | packet loss due to occasional longer drop-outs. |
|
|
97 | - send RST when a positive window size violation is detected, but |
|
|
98 | not in other cases, to reconnect more quickly. |
|
|
99 | - upgraded liblzf to version 3.4. |
|
|
100 | - dropped -fno-exceptions due to ev++.h using it. |
|
|
101 | - node-up/down scripts are now run in sequence. |
|
|
102 | - new -q switch for gvpectrl, for when you run it often. |
|
|
103 | - work around the horribly inconsistent, ad-hoc, ever-changing |
|
|
104 | and broken texinfo syntax. YMMV. avoid texinfo. |
|
|
105 | - keepalive is more aggressive now, sensding ping's every 3 seconds |
|
|
106 | and killing the conenction after 15 seconds. |
|
|
107 | - bugfixes. |
|
|
108 | - autoconf 2.69, automake 1.11. |
|
|
109 | |
|
|
110 | 2.01 Thu Mar 29 19:26:04 CEST 2007 |
|
|
111 | - protocol version 0.1, compatible with older releases. |
|
|
112 | - bugfix of callback.h, might have cause callback return values to |
|
|
113 | be corrupted on architectures like sparc before. |
|
|
114 | - dns transport retries more aggressively. |
|
|
115 | - updated documentation, improved dns transport reliability |
|
|
116 | and throughput. |
|
|
117 | - added experimental support for sha256 and sha512 digests. |
|
|
118 | |

126 | your ip address changed, which is *required*. |
|
|
127 | - sets close-on-exec flag on tcp connections. This fixes a bug |
|
|
128 | where child processes kept tcp connections open and caused |
|
|
129 | connections to fail when only one side can connect. |
|
|
130 | - fixed a bug in receive sequence checking that made gvpe |
|
|
131 | accept out-of-window packets in most cases. |
| 11 | - tighter limit for the maximum sequence # to avoid overflow |
