* Wed Jun 23 2004 David Parrish 2.0.0 - Major release - Completely replace active/standby clustering with a new peer-to-peer clustering method which allows much greater throughput and is a lot more fault tolerant - Add internal tbf implementation for throttling without relying on tc and kernel HTB - Add support for iBGP and eBGP to advertise routes - Add cli commands "show cluster", "show bgp", "show ipcache", "show throttle", "show tbf", "suspend bgp", "restart bgp", "show user" - Interception destination must be set per-user - If SMP machine, allow use of SCHED_FIFO, which should improve performance - Added config option to send GARP at startup - Added plugin_become_master and plugin_new_session_master plugin hooks - Remove useless sessionsendarp(). This isn't needed now that we are using TUN instead of TAP. - ICMP rate limiting so not every unreachable packet is replied with an ICMP unreachable message - mangle table is not required on anything but the cluster master, so slaves will drop the mangle table and attempt to unload the ip_conntrack module - Statically assigned IP addresses (by Radius) work now - Add -d command-line flag to detach and become a daemon - Configuration file is now "/etc/l2tpns/startup-config" - Reduced MIN_IP_SIZE to 0x19 to stop a pile of Short IP warnings - Resend initial IPCP request until it's acknowleged by the client - Better radius session cleanup logic - Many miscellaenous bugfixes and performance enhancements - Thanks to Michael O'Reilly and Brendan O'Dea for most of these new features * Mon May 24 2004 David Parrish 1.2.0 - Fix SEGFAULT in garden module - Use multiple radius sockets to allow more concurrent authentication requests - Add username parameter to "show users" command - Fix counting tunnel rx errors as tunnel tx errors - Add "show throttle" command - Add gcc __attribute__ to logging functions - Fix warnings shown by __attribute__ - Make sure regular cleanup happens regularly under high load - Add variable cleanup_interval for changing cleanup interval - Add support for reading more than one packet per fd in each processing loop - This is configurable with the multi_read_count variable - Remove segv handler so core dumps can happen - Use nonblocking sockets - Increase tun queue length - Fix minimum length of IP packets - Remove per-packet plugin hooks (they are slow) - Don't drop session if no free RADIUS - Don't expire more than 1000 sessions per cleanup interval - Remove -a and -c command-line options. They don't work anyway - Don't require file: in log_filename - Bump version to 1.2.0 - Check return code when throttling users * Mon Apr 5 2004 David Parrish 1.1.1 - Don't mention configure anymore, it's not used - Added the autosnoop and autothrottle modules - Don't default to using a htb for the class root * Fri Mar 5 2004 David Parrish 1.1.0 - Change all strcpy() calls to strncpy() to avoid buffer overflow potential - Add ICMP host unreachable support - Logging to syslog if log_file = "syslog:facility" - Now requires libcli 1.5 - All configuration moves to a config structure - Ability to modify and write config on the fly through command-line interface - Config file support is removed, and now handled by the cli - Show hostname in cli prompt - Keep current state type for tunnels - Add uptime command do CLI, which also shows real-time bandwidth utilisation - Add goodbye command to cluster master, which forces droppping a slave - Cache IP address allocation, so that reconnecting users get the same address - Fix tunnel resend timeouts, so that dead tunnels will be cleaned up - Allocate tunnels and radius without using a linked list which had issues - Fix some off-by-one errors in tunnel and session and radius arrays - Save and reload ip address pool when dieing - Check version and size of reloaded data when restarting - Remove plugin_config support - Remove old support for TBF which didn't work anyway. HTB is required to do throttling now. - Add COPYING and Changes files
