Caught + by Karl Kleinpaste and Marcus Kong. + +2.2 Mon Sep 1 06:28:09 CEST 2008 + - protocol version 0.1, compatible with older releases, + but upgrade is recommended to due changed ondemand behaviour. + - new per-node options max-ttl and max-queue. + - convert from iom.C to libev, a high-performance event loop + (http://software.schmorp.de/pkg/libev). + - tcp connections were leaking in some cases. + - retry more aggressively (once/s) to establish a connection if + new packets arrive for it. + - save a lot of setsockopt calls when the tos doesn't change. + - honor disabled even on initial connect attempt. + - changed callback mechanism to be slightly less portable + but more efficient mechanism (standards-compliant c++ compilers + should work). + - increased receive window positive size, to allow for massive + packet loss due to occasional longer drop-outs. + - send RST when a positive window size violation is detected, but + not in other cases, to reconnect more quickly. + - upgraded liblzf to version 3.4. + - dropped -fno-exceptions due to ev++.h using it. + - node-up/down scripts are now run in sequence. + - new -q switch for gvpectrl, for when you run it often. + - work around the horribly inconsistent, ad-hoc, ever-changing + and broken texinfo syntax.

This fixes a bug where + gvpe sent packets to the old ip address of another host + even though it had received packets from it's new address. + This only causes problems if you forget to -HUP your gvpe after + your ip address changed, which is *required*. + - sets close-on-exec flag on tcp connections. This fixes a bug + where child processes kept tcp connections open and caused + connections to fail when only one side can connect. + - fixed a bug in receive sequence checking that made gvpe + accept out-of-window packets in most cases. + - tighter limit for the maximum sequence # to avoid overflow + conditions + allow more headroom for packet reordering. + - replace some asserts that trapped config mismatches by + more useful log messages. + - fix spurious extra newline in some log messages. + +1.9 Tue Apr 19 06:21:50 CEST 2005 + - protocol version 0.1, compatible with older releases. + - WARNING: this version checks the return value of if-up etc. + scripts and exits on failure. + - IMPORTANT: run if-up/node-up etc. scripts via /bin/sh. + - IMPORTANT: interface initialization (MAC, MTU) is now done + automatically in most configurations. + - options can now be specified on the gvpe command line, too. + - make some DNS transport values configurable and document them. + - improved OS specific information in gvpe.osdep(5). + - new tap device type "native/darwin", that supports the tap + driver available for darwin (thanks to matthew mead who tested + it out with me in a long session). tincd/darwin is still available. + - new device type "tincd/bsd", which is a newer version of the + *bsd-drivers taken from tinc. + - fixed a bug in relying on the order of global construction + when tcp transport was enabled. The fix makes it use no + cpu time unless it is in use, too. + - information about other nodes is now available to if-up etc. scripts. + - the value of the config variable if-up-data is passed to the if-up + etc. scripts. + - skip unparsable config lines with a warning instead of stopping + parsing and continuing with a certainly unusable config. + +1.8 Fri Mar 18 00:58:55 CET 2005 + - protocol version 0.1, compatible with older releases. + - enable-udp = yes is now default only when no other protocols + are enabled. otherwise it is disabled unless explicitly enabled. + - implemented dns tunneling (experimental now and in the future). + - remove support for pre-release version protocol. + - updated tincd drivers (rev 1433), added uml_socket driver, documented + tincd drivers a bit better. + - document icmp configuration values. + - document transport protocols in gvpe.protocol(7). + - remove unused ChangeLog file. + - created a mailinglist at gvpe@lists.schmorp.de. + - added an exemption to allow distribution of binaries linked against + OpenSSL, as suggested by Guus Sliepen (author of tinc).
