Not maintained anymore; use clustering + to retain state across restarts. +- Ensure that sessionkill is not called on an unopened session (borks + the freelist). +- Bump MAXSESSION to 60K. +- Fix off-by-one errors in session/tunnel initialisation and + sessiont <-> sessionidt functions. +- Use session[s].opened consistently when checking for in-use sessions + (rather than session[s].tunnel). +- Use <= cluster_highest_sessionid rather than < MAXSESSION in a + couple of loops. +- Don't kill a whole tunnel if we're out of sessions. +- Change session[s].ip to 0 if set from RADIUS to 255.255.255.254; + avoids the possibility that it will be interpreted as a valid IP + address. +- Avoid a possible buffer overflow in processpap. +- Kill session if authentication was rejected. +- Simplify AVP unhiding code. +- Add optional "username" parameter to ungarden control, allowing the + username to be reset before going online. +- Add result/error codes and message to StopCCN when shutting down tunnels. +- Add result/error codes to CDN when shutting down sessions. Sends 2/7 + (general error, try another LNS) when out of IP addresses, and 3 + (adminstrative) for everything else (suggestion from Chris Gates). +- Only send RADIUS stop record in sessionshutdown when there's an ip address. +- Reset .die on master takeover (so that dying sessions don't have to + hang around until the new master has the same uptime as the old one). +- Update .last_packet in cluster_handle_bytes only when there have + been bytes received from the modem (dead sessions were having the + idle timeout reset by stray packets). +- Use cli_error() for error messages and help. +- Add a Cisco-Avpair with intercept details to RADIUS Start/Stop + records. +- Don't use LOG() macro in initdata() until the config struct has been + allocated (uses config->debug). +- Initialise log_stream to stderr to catch errors before the config file + is read. +- Fix leak in session freelist when initial RADIUS session allocation + fails. +- Make "show running-config" a privileged command (contains clear text + shared secrets). +- Add sessionctl plugin to provide drop/kill via nsctl. +- Add handling of "throttle=N" RADIUS attributes. +- Fix RADIUS indexing (should have 16K entries with 64 sockets). +- Cluster changes from Michael, intended to prevent a stray master + from trashing a cluster: + + Ignore heartbeats from peers claiming to be the master before the + timeout on the old master has expired. + + A master receiving a stray heartbeat sends a unicast HB back, which + should cause the rogue to die due to the tie-breaker code. + + Keep probing the master for late heartbeats. + + Drop BGP as soon as we become master with the minumum required peers. + + Any PING seen from a master forces an election (rather than just + where basetime is zero). + + A slave which receives a LASTSEEN message (presumably a restarted + master) sends back new message type, C_MASTER which indicates the + address of the current master. +- New config option: cluster_master_min_adv which determines the minimum + number of up to date slaves required before the master will drop + routes. +- New config option: allow_duplicate_users which determines whether + or not to kill older sessions with the same username. + +* Fri Dec 17 2004 Brendan O'Dea 2.0.13 +- Better cluster master collision resolution: keep a counter of state + changes, propagated in the heartbeats; the master with the highest # + of changes (that has kept in contact with the LAC through the + outage) prevails. +- Skip newlines in ringbuffer messages to CLI. +- Drop "Session N is closing" message level to 4; don't process PPPIP + packets in this state. +- Use gzip --best for man pages, include pid_file in sample + startup-config (from Jonathan's Debian package patches). +- Read multiple packets off cluster_sockfd as well as udpfd, tunfd in an + attempt to avoid losing the cluster in high load (DoS) conditions. +- Add counters for select_called, multi_read_used and multi_read_exceeded. +- Compress logs. +- Retain counters of shutdown sessions to dump once per minute. +- Use standard uintN_t types for portability. + +* Wed Dec 1 2004 Brendan O'Dea 2.0.12 +- The "This time, for sure!" release. +- Fix throttlectl plugin argument parsing. + +* Wed Dec 1 2004 Brendan O'Dea 2.0.11 +- Don't send a RADIUS start record when ungardening on shutdown. + +* Wed Dec 1 2004 Brendan O'Dea 2.0.10 +- Fix byte ordering of LCP header length (thanks Yuri). +- Increase ip_conntrack_max due to dropped packets. + +* Tue Nov 30 2004 Brendan O'Dea 2.0.9 +- Revise CCP, send ConfigReq once only. +- Don't copy the old buffer into Config{Nak,Rej} LCP responses (oops); + add length checks when appending. +- Do copy the identifier from the request and update length. +- Have makeppp print a backtrace on overflow. +- Check control serial before clearing window, prevents looping tunnel + setup in some instances. +- Implement named access-lists which may be applied to a session + either via Filter-Id RADIUS responses, or using the CLI. +- Drop ip address from LOG. +- autothrottle: revise parsing; ignore lcp:interface-config avpairs + which don't start with serv[ice-policy]. +- Add THANKS file. + +* Sat Nov 20 2004 Brendan O'Dea 2.0.8 +- Ignore gateway address in Framed-Route (from Jonathan McDowell). +- Don't route Framed-IP-Address if contained in a Framed-Route. +- Call sessionshutdown() when a tunnel is dropped rather than + sessionkill() to ensure that RADIUS stop records are sent. +- Cleanup: make a bunch of global functions/variables static. +- Remove reference to old -a command line argument. +- Add l2tpns(8) and nsctl(8) manpages from Jonathan McDowell. +- Add startup-config(5) manpage. +- Revise nsctl to allow arbitrary strings/args to be passed to plugins. +- Add snoopctl, throttlectl plugins. +- Fix deletion from linked list. +- Allow LCP re-negotiation after connection completes (thanks Yuri). + +* Mon Nov 15 2004 Brendan O'Dea 2.0.7 +- Fix socket creation in host_unreachable() (thanks to Bjørn Augestad) +- Don't assume BGP peer sends back negotiated hold time, pick smallest + * Thu Nov 11 2004 Brendan O'Dea 2.0.6 - Make BGP keepalive/hold time configurable - Revise BGP config to use "router bgp AS" syntax (requires libcli >= 1.8.2) @@ -173,4 +316,3 @@ - Remove plugin_config support - Remove old support for TBF which didn't work anyway.
