+* Wed Aug 10 2005 Brendan O'Dea <bod@optus.net> 2.1.2
+- Clear cluster_master on election so that slaves will accept a new master.
+- Provide more comments/defaults in etc/startup-config.default.
+- Add DAE support (PoD/CoA) from Vladislav Bjelic.
+- Clean up new warnings from gcc 4.0.
+- Replace flags used for LCP/IPCP with state machine.
+- Include Acct-Session-Time in interim records.
+- Fix DAE vector, generateload (Alex Kiernan).
+- Replace RSA MD5 with public domain version.
+
+* Tue Jun 14 2005 Brendan O'Dea <bod@optusnet.com.au> 2.1.1
+- Add missing newline to backtrace macro.
+- Don't send CDN for each session when shutting down tunnels (this is
+  implicit).
+- Move tunnel shutdown from SIGQUIT signal handler to be run once from
+  still_busy().  Reject new tunnels/sessions while in the process of
+  shutting down.
+- Clarify usage of shutdown signals in documentation.
+- Always initialise PRNG.
+- Sanity check length of random_vector.
+- Fix segv in unhide_value.
+- Ping new master when we get C_MASTER and delay next election to allow
+  the unicast limp-along code to kick in if required.

 - Add IPv6 support from Jonathan McDowell.
 - Add CHAP support from Jordan Hrycaj.
 - Add interim accounting support from Vladislav Bjelic.
 - Negotiate MRU, default 1458 to avoid fragmentation.
 - Sanity check that cluster_send_session is not called from a child
   process.

-- Throttle outgoing LASTSEEN packets to at most one per second for a
-  given seq#.
-- More DoS prevention: add packet_limit option to apply a hard limit
-  to downstream packets per session.

 - Use bounds-checking lookup functions for string constants.
 - Add enum for RADIUS codes.
 - Make "call_" prefix implict in CSTAT() macro.
 - Fix some format string problems.

-- 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".

 - Remove "save_state" option.  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 to CDN when shutting down sessions.  Sends 2/7

-- Only send RADIUS stop record in sessionshutdown when there's an ip address.

-- Update .last_packet in cluster_handle_bytes only when there have

+- New config option: allow_duplicate_users which determines whether
+  or not to kill older sessions with the same username.
+- Fix byte counters in accounting records.
+- Add Acct-Output-Gigawords, Acct-Input-Gigawords attributes to RADIUS
+  accounting packets.
+- Fix icmp host unreachable to use router address.
+- Include endpoint address in accounting dump files.
+- Convert mainloop to use epoll rather than select.
+- 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).
