-* Mon Jan 10 2005 Brendan O'Dea <bod@optusnet.com.au> 2.1.0
-- Add IPv6 support from Jonathan McDowell (work in progress).
-- Add CHAP support from Jordan Hrycaj (work in progress).
+* Sun Jun 12 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.

+* Sun Jun 5 2005 Brendan O'Dea <bod@optusnet.com.au> 2.1.0
+- 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".
+- Remove "save_state" option.  Not maintained anymore; use clustering
+  to retain state across restarts.
+- 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).
+- 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).
+- Initialise log_stream to stderr to catch errors before the config file
+  is read.
+- Make "show running-config" a privileged command (contains clear text
+  shared secrets).
+- Add sessionctl plugin to provide drop/kill via nsctl.
+- 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).
+- 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
