- Add IPv6 support from Jonathan McDowell.
-- Add CHAP support from Jordan Hrycaj (work in progress).
+- 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
(general error, try another LNS) when out of IP addresses, and 3
(adminstrative) for everything else (suggestion from Chris Gates).
-- 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).
- Use cli_error() for error messages and help.
-- Add a Cisco-Avpair with intercept details to RADIUS Start/Stop
- records.
- 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.

+ 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.

+ 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:

+ fails.

+ + 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.
