192 + Show session open time in "show session"/"show user" detailed output.
193 + Have slaves with BGP configured drop BGP on receipt of a shutdown
194 signal, but hang about for an additional 5s to process any remaining
196 + Run regular_cleanups after processing the results of the select,
197 looking at a sufficient slice of each table to ensure that all
198 entries are examined at least once per second.
200 + Cluster changes from Michael, intended to prevent a stray master
201 from trashing a cluster:
202 = Ignore heartbeats from peers claiming to be the master before the
203 timeout on the old master has expired.
204 = A master receiving a stray heartbeat sends a unicast HB back, which
205 should cause the rogue to die due to the tie-breaker code.
206 = Keep probing the master for late heartbeats.
207 = Drop BGP as soon as we become master with the minumum required peers.
208 = Any PING seen from a master forces an election (rather than just
209 where basetime is zero).
210 = A slave which receives a LASTSEEN message (presumably a restarted
211 master) sends back new message type, C_MASTER which indicates the
212 address of the current master.
213 + New config option: cluster_master_min_adv which determines the minimum
214 number of up to date slaves required before the master will drop
217 + Add handling of "throttle=N" RADIUS attributes.
218 + Fix RADIUS indexing (should have 16K entries with 64 sockets).
220 + Fix leak in session freelist when initial RADIUS session allocation
223 + Add a Cisco-Avpair with intercept details to RADIUS Start/Stop
226 + Only send RADIUS stop record in sessionshutdown when there's an ip address.
227 + Reset .die on master takeover (so that dying sessions don't have to
228 hang around until the new master has the same uptime as the old one).
229 + Update .last_packet in cluster_handle_bytes only when there have
230 been bytes received from the modem (dead sessions were having the
231 idle timeout reset by stray packets).
233 + Ensure that sessionkill is not called on an unopened session (borks
235 + Bump MAXSESSION to 60K.
236 + Fix off-by-one errors in session/tunnel initialisation and
237 sessiont <-> sessionidt functions.
238 + Use session[s].opened consistently when checking for in-use sessions
239 (rather than session[s].tunnel).
240 + Use <= cluster_highest_sessionid rather than < MAXSESSION in a
242 + Don't kill a whole tunnel if we're out of sessions.
243 + Change session[s].ip to 0 if set from RADIUS to 255.255.255.254;
244 avoids the possibility that it will be interpreted as a valid IP
246 + Avoid a possible buffer overflow in processpap.
247 + Kill session if authentication was rejected.
249 + More DoS prevention: add packet_limit option to apply a hard limit
250 to downstream packets per session.
251 + Fix "clear counters".
252 + Log "Accepted connection to CLI" at 4 when connection is from localhost
253 to reduce noise in logs.
254 + Show time since last counter reset in "show counters".
256 + Throttle outgoing LASTSEEN packets to at most one per second for a

265 - Drop "Session N is closing" message level to 4; don't process PPPIP
