+ 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).
+- Use cli_error() for error messages and help.
+- Don't use LOG() macro in initdata() until the config struct has been
+ allocated (uses config->debug).

+ is read.
+- Make "show running-config" a privileged command (contains clear text
+ shared secrets).

+- New config option: allow_duplicate_users which determines whether
+ or not to kill older sessions with the same username.

+- Add note about fragmentation in Docs/manual.html, and a sample
+ iptables rule for MSS clamping.
+- Merge 2.0.22:
+ + Show session open time in "show session"/"show user" detailed output.
+ + Have slaves with BGP configured drop BGP on receipt of a shutdown
+ signal, but hang about for an additional 5s to process any remaining
+ traffic.
+ + Run regular_cleanups after processing the results of the select,
+ looking at a sufficient slice of each table to ensure that all
+ entries are examined at least once per second.
+- Merge 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 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.
+- Merge 2.0.20:
+ + Add handling of "throttle=N" RADIUS attributes.
+ + Fix RADIUS indexing (should have 16K entries with 64 sockets).
+- Merge 2.0.19:
+ + Fix leak in session freelist when initial RADIUS session allocation
+ fails.
+- Merge 2.0.18:
+ + Add a Cisco-Avpair with intercept details to RADIUS Start/Stop
+ records.
+- Merge 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).
+- Merge 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.
+- Merge 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".
+- Merge 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

+- 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.
- 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
