2.2 Mon Sep 1 06:28:09 CEST 2008 |
| 4 |
- protocol version 0.1, compatible with older releases, |
| 5 |
but upgrade is recommended to due changed ondemand behaviour. |
| 6 |
- new per-node options max-ttl and max-queue. |
| 7 |
- convert from iom.C to libev, a high-performance event loop |
| 8 |
(http://software.schmorp.de/pkg/libev). |
| 9 |
- tcp connections were leaking in some cases. |
| 10 |
- retry more aggressively (once/s) to establish a connection if |
| 11 |
new packets arrive for it. |
| 12 |
- save a lot of setsockopt calls when the tos doesn't change. |
| 13 |
- honor disabled even on initial connect attempt. |
| 14 |
- changed callback mechanism to be slightly less portable |
| 15 |
but more efficient mechanism (standards-compliant c++ compilers |
| 16 |
should work). |
| 17 |
- increased receive window positive size, to allow for massive |
| 18 |
packet loss due to occasional longer drop-outs. |
| 19 |
- send RST when a positive window size violation is detected, but |
| 20 |
not in other cases, to reconnect more quickly. |
| 21 |
- upgraded liblzf to version 3.4. |
| 22 |
- dropped -fno-exceptions due to ev++.h using it. |
| 23 |
- node-up/down scripts are now run in sequence. |
| 24 |
- new -q switch for gvpectrl, for when you run it often. |
| 25 |
- work around the horribly inconsistent, ad-hoc, ever-changing |
| 26 |
and broken texinfo syntax. YMMV. avoid texinfo. |
| 27 |
- keepalive is more aggressive now, sensding ping's every 3 seconds |
| 28 |
and killing the conenction after 15 seconds. |
| 29 |
- bugfixes. |
| 30 |
|
| 31 |
2.01 Thu Mar 29 19:26:04 CEST 2007 |
| 32 |
- protocol version 0.1, compatible with older releases. |
| 33 |
- bugfix of callback.h, might have cause callback return values to |
| 34 |
be corrupted on architectures like sparc before. |
| 35 |
- dns transport retries more aggressively. |
| 36 |
- updated documentation, improved dns transport reliability |
| 37 |
and throughput. |
| 38 |
- added experimental support for sha256 and sha512 digests. |
| 39 |
|

2.0 Mon Dec 5 13:59:26 CET 2005 |
| 41 |
- protocol version 0.1, compatible with older releases. |
| 42 |
- implement allow-direct, deny-direct node config statements. |
| 43 |
- implemented != for sockinfo. This fixes a bug where |
| 44 |
gvpe sent packets to the old ip address of another host |
| 45 |
even though it had received packets from it's new address. |
| 46 |
This only causes problems if you forget to -HUP your gvpe after |
| 47 |
your ip address changed, which is *required*. |
| 48 |
- sets close-on-exec flag on tcp connections. This fixes a bug |
| 49 |
where child processes kept tcp connections open and caused |
| 50 |
connections to fail when only one side can connect. |
| 51 |
- fixed a bug in receive sequence checking that made gvpe |
| 52 |
accept out-of-window packets in most cases. |
| 53 |
- tighter limit for the maximum sequence # to avoid overflow |
| 54 |
conditions + allow more headroom for packet reordering. |
| 55 |
- replace some asserts that trapped config mismatches by |
| 56 |
more useful log messages. |
| 57 |
- fix spurious extra newline in some log messages. |
| 58 |
|
| 59 |
1.9 Tue Apr 19 06:21:50 CEST 2005 |
| 60 |
- protocol version 0.1, compatible with older releases. |
| 61 |
- WARNING: this version checks the return value of if-up etc. |
| 62 |
scripts and exits on failure. |
| 63 |
- IMPORTANT: run if-up/node-up etc. scripts via /bin/sh. |
| 64 |
- IMPORTANT: interface initialization (MAC, MTU) is now done |
| 65 |
automatically in most configurations. |
| 66 |
- options can now be specified on the gvpe command line, too. |
| 67 |
- make some DNS transport values configurable and document them. |
| 68 |
- improved OS specific information in gvpe.osdep(5). |
| 69 |
- new tap device type "native/darwin", that supports the tap |
| 70 |
driver available for darwin (thanks to matthew mead who tested |
| 71 |
it out with me in a long session). tincd/darwin is still available. |
| 72 |
- new device type "tincd/bsd", which is a newer version of the |
| 73 |
*bsd-drivers taken from tinc. |
| 74 |
- fixed a bug in relying on the order of global construction |
| 75 |
when tcp transport was enabled. The fix makes it use no |
| 76 |
cpu time unless it is in use, too. |
| 77 |
- information about other nodes is now available to if-up etc. scripts. |
| 78 |
- the value of the config variable if-up-data is passed to the if-up |
| 79 |
etc. scripts. |
| 80 |
- skip unparsable config lines with a warning instead of stopping |
| 81 |
parsing and continuing with a certainly unusable config. |
| 82 |
|
| 83 |
1.8 Fri Mar 18 00:58:55 CET 2005 |
| 84 |
- protocol version 0.1, compatible with older releases. |
| 85 |
- enable-udp = yes is now default only when no other protocols |
| 86 |
are enabled. otherwise it is disabled unless explicitly enabled. |
| 87 |
- implemented dns tunneling (experimental now and in the future). |
| 88 |
- remove support for pre-release version protocol. |
| 89 |
- updated tincd drivers (rev 1433), added uml_socket driver, documented |
| 90 |
tincd drivers a bit better. |
| 91 |
- document icmp configuration values. |
| 92 |
- document transport protocols in gvpe.protocol(7). |
| 93 |
- remove unused ChangeLog file. |
| 94 |
- created a mailinglist at gvpe@lists.schmorp.de. |
| 95 |
- added an exemption to allow distribution of binaries linked against |
| 96 |
OpenSSL, as suggested by Guus Sliepen (author of tinc). No |
| 97 |
GNUTLS conversion in sight. |
| 98 |
- some portability fixes with respect to --disable-nls. |
| 99 |
|
| 100 |
1.7 Tue Feb 22 23:58:59 CET 2005 |
| 101 |
- protocol version 0.1, compatible with older releases. |
| 102 |
- first gnu release. |
| 103 |
- documented the special value 1 for router-priority. |
| 104 |
- renamed vped => gvpe and vpectrl => gvpectrl, as well as |
| 105 |
vped.conf => gvpe.conf. |
| 106 |
- new per-node option "max-retry". |
| 107 |
- asymmetric rekeying behaviour, so hosts don't rekey simultaneously. |
| 108 |
- new configure option --enable-static-daemon. |
| 109 |
- fix configure --help output. |
| 110 |
- many documentation layout fixes. |
| 111 |
- synced iom.[Ch] from rxvt-unicode. |
| 112 |
- try to cope with some non-monotonic time changes. |
| 113 |
- revert to locale.h - a usual, clocale is nonfunctioning on macosx. |
| 114 |
- considerably improved pod2texi and the resulting texi doc. |
| 115 |
|
| 116 |
1.6.1 Wed May 12 14:48:20 CEST 2004 |
| 117 |
- protocol version 0.1, compatible with older releases. |
| 118 |
- fix -c switch that has been broken due to a last-minute fix |
| 119 |
to option and config file parsing. |
| 120 |
|
| 121 |
1.6 Mon May 10 20:55:10 CEST 2004 |
| 122 |
- protocol version 0.1, compatible with older releases. |
| 123 |
- do not RESET on out-of-sequence packets (good for wireless). |
| 124 |
- various non-security-related bugfixes. |
| 125 |
- c++ify (at least make it compile with g++-3.4, which should make |
| 126 |
it a little bit more standard c++). |
| 127 |
|
| 128 |
1.5 Fri Jan 30 00:50:04 CET 2004 |
| 129 |
- protocol version 0.1, compatible with older releases. |
| 130 |
- vped will refuse to start when hostkey and public key do not match. |
| 131 |
- updated lzf code to version 1.2. |
| 132 |
- better error reporting for "unusual" conditions, like failing |
| 133 |
to allocate memory, that should not normally happen and |
| 134 |
will otherwise result in spurious other error messages. Also |
| 135 |
adds paranoid checks in case openssl's API changes in a bad way. |
| 136 |
- fix a bug where queued vpn packets were cleared to zero. while |
| 137 |
this doesn't affect security, it did cause warning messages and |
| 138 |
unnecessary connectivity delays. |
| 139 |
|
| 140 |
1.4 Sat Jan 17 15:49:21 CET 2004 |
| 141 |
- protocol version 0.1, compatible with older releases. |
| 142 |
- better retry behaviour on key mismatch. |
| 143 |
- use select-based io_manager instead of poll-based one. |
| 144 |
- share io manager between rxvt-unicode and vpe. |
| 145 |
- sooo many *BSD workarounds because no BSD I could find is even |
| 146 |
remotely POSIX-compatible. |
| 147 |
|
| 148 |
1.2 Fri Oct 17 03:44:44 CEST 2003 |
| 149 |
- protocol version 0.1. |
| 150 |
- tincd kernel interface code imported, more supported platforms |
| 151 |
(native/linux (2.4), tincd/linux (2.2 and 2.4), tincd/freebsd, |
| 152 |
native/cygwin). |
| 153 |
- added primitive ethernet emulation (ipv4 only), which allows |
| 154 |
the following platforms that only have tun drivers to work: |
| 155 |
/* none yet tested */ |
| 156 |
- portability workarounds, especially for unfriendly freebsd |
| 157 |
- very minor bugfixes |
| 158 |
- warnings when choosing insecure ciphers/hashes |
| 159 |
- reduced default hmac length to 8. |
| 160 |
- cvs now contains configure, Makefile.in and other generated files. |
| 161 |
- added doc/complex-example to the distribution. |
| 162 |
|
| 163 |
1.0 distant past |
| 164 |
- protocol version 0.1. |
| 165 |
- tweaked various timeouts to help very slow (486) class |
| 166 |
machines or nets with many hosts. |
| 167 |
- tweaked rate-limiting to be more forgiving for hosts |
| 168 |
connecting through routers (not a fix). |
| 169 |
