1 * Sun May 8 2005 Brendan O'Dea <bod@optusnet.com.au> 2.1.0
2 - Add IPv6 support from Jonathan McDowell.
3 - Add CHAP support from Jordan Hrycaj.
4 - Add interim accounting support from Vladislav Bjelic.
5 - Negotiate MRU, default 1458 to avoid fragmentation.
6 - Sanity check that cluster_send_session is not called from a child
8 - Throttle outgoing LASTSEEN packets to at most one per second for a
10 - More DoS prevention: add packet_limit option to apply a hard limit
11 to downstream packets per session.
12 - Use bounds-checking lookup functions for string constants.
13 - Add enum for RADIUS codes.
14 - Make "call_" prefix implict in CSTAT() macro.
15 - Fix some format string problems.
16 - Fix "clear counters".
17 - Log "Accepted connection to CLI" at 4 when connection is from localhost
18 to reduce noise in logs.
19 - Show time since last counter reset in "show counters".
20 - Remove "save_state" option. Not maintained anymore; use clustering
21 to retain state across restarts.
22 - Ensure that sessionkill is not called on an unopened session (borks
24 - Bump MAXSESSION to 60K.
25 - Fix off-by-one errors in session/tunnel initialisation and
26 sessiont <-> sessionidt functions.
27 - Use session[s].opened consistently when checking for in-use sessions
28 (rather than session[s].tunnel).
29 - Use <= cluster_highest_sessionid rather than < MAXSESSION in a
31 - Don't kill a whole tunnel if we're out of sessions.
32 - Change session[s].ip to 0 if set from RADIUS to 255.255.255.254;
33 avoids the possibility that it will be interpreted as a valid IP
35 - Avoid a possible buffer overflow in processpap.
36 - Kill session if authentication was rejected.
37 - Simplify AVP unhiding code.
38 - Add optional "username" parameter to ungarden control, allowing the
39 username to be reset before going online.
40 - Add result/error codes and message to StopCCN when shutting down tunnels.
41 - Add result/error codes to CDN when shutting down sessions. Sends 2/7
42 (general error, try another LNS) when out of IP addresses, and 3
43 (adminstrative) for everything else (suggestion from Chris Gates).
44 - Only send RADIUS stop record in sessionshutdown when there's an ip address.
45 - Reset .die on master takeover (so that dying sessions don't have to
46 hang around until the new master has the same uptime as the old one).
47 - Update .last_packet in cluster_handle_bytes only when there have
48 been bytes received from the modem (dead sessions were having the
49 idle timeout reset by stray packets).
50 - Use cli_error() for error messages and help.
51 - Add a Cisco-Avpair with intercept details to RADIUS Start/Stop
53 - Don't use LOG() macro in initdata() until the config struct has been
54 allocated (uses config->debug).
55 - Initialise log_stream to stderr to catch errors before the config file
57 - Fix leak in session freelist when initial RADIUS session allocation
59 - Don't process C_LASTSEEN unless we're a master (otherwise a crashed
60 master kills all slaves once restarted).
62 * Fri Dec 17 2004 Brendan O'Dea <bod@optusnet.com.au> 2.0.13
63 - Better cluster master collision resolution: keep a counter of state
64 changes, propagated in the heartbeats; the master with the highest #
65 of changes (that has kept in contact with the LAC through the
67 - Skip newlines in ringbuffer messages to CLI.
68 - Drop "Session N is closing" message level to 4; don't process PPPIP
69 packets in this state.
70 - Use gzip --best for man pages, include pid_file in sample
71 startup-config (from Jonathan's Debian package patches).
72 - Read multiple packets off cluster_sockfd as well as udpfd, tunfd in an
73 attempt to avoid losing the cluster in high load (DoS) conditions.
74 - Add counters for select_called, multi_read_used and multi_read_exceeded.
76 - Retain counters of shutdown sessions to dump once per minute.
77 - Use standard uintN_t types for portability.

95 - Have makeppp print a backtrace on overflow.

99 either via Filter-Id RADIUS responses, or using the CLI.

112 - Add l2tpns(8) and nsctl(8) manpages from Jonathan McDowell.
