+* Sun May 22 2005 Brendan O'Dea <bod@optusnet.com.au> 2.0.21
+- 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 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.
+
+* Mon May 16 2005 Brendan O'Dea <bod@optusnet.com.au> 2.0.20
+- Add handling of "throttle=N" RADIUS attributes.
+- Fix RADIUS indexing (should have 16K entries with 64 sockets).
+
+* Sat May 7 2005 Brendan O'Dea <bod@optusnet.com.au> 2.0.19
+- Fix leak in session freelist when initial RADIUS session allocation
+ fails.
+
+* Tue May 3 2005 Brendan O'Dea <bod@optusnet.com.au> 2.0.18
+- Add a Cisco-Avpair with intercept details to RADIUS Start/Stop
+ records.
+
+* Mon May 2 2005 Brendan O'Dea <bod@optusnet.com.au> 2.0.17
+- 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).
+
+* Mon Feb 14 2005 Brendan O'Dea <bod@optusnet.com.au> 2.0.16
+- 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.
+
+* Thu Jan 13 2005 Brendan O'Dea <bod@optusnet.com.au> 2.0.15
+- More DoS prevention: add packet_limit option to apply a hard limit
+ to downstream packets per session.
+- Fix "clear counters".
+- Log "Accepted connection to CLI" at 4 when connection is from localhost
+ to reduce noise in logs.
+- Show time since last counter reset in "show counters".
+
+* Mon Dec 20 2004 Brendan O'Dea <bod@optusnet.com.au> 2.0.14
+- Throttle outgoing LASTSEEN packets to at most one per second for a
+ given seq#.
+
+* Fri Dec 17 2004 Brendan O'Dea <bod@optusnet.com.au> 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 <bod@optusnet.com.au> 2.0.12
+- The "This time, for sure!" release.
+- Fix throttlectl plugin argument parsing.
+
+* Wed Dec 1 2004 Brendan O'Dea <bod@optusnet.com.au> 2.0.11
+- Don't send a RADIUS start record when ungardening on shutdown.
+
+* Wed Dec 1 2004 Brendan O'Dea <bod@optusnet.com.au> 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 <bod@optusnet.com.au> 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 <bod@optusnet.com.au> 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 <bod@optusnet.com.au> 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 <bod@optusnet.com.au> 2.0.6
+- Make BGP keepalive/hold time configurable
+- Revise BGP config to use "router bgp AS" syntax (requires libcli >= 1.8.2)
+
+* Tue Nov 9 2004 Brendan O'Dea <bod@optusnet.com.au> 2.0.5
+- Handle routing properly in lone-master case
+- Fix intercepts: don't double-snoop throttled customers, ensure
+ byte/packet counts are only updated once
+- Add a callback to allow plugins to fetch values from the running config
+
+* Mon Nov 8 2004 Brendan O'Dea <bod@optusnet.com.au> 2.0.4
+- Added setrxspeed plugin
+- Added peer_address config option
+- Rename wrapper macros to LOG()/LOG_HEX(), use p->log() in plugins
+- Replace some PPP{PAP,CHAP} magic numebrs with constants
+- Nak asyncmap (unless == 0)
+- Bundle ConfigRej options
