-- Fix off-by-one in session/tunnel table initialisation.
+- Ensure that sessionkill is not called on an unopened session (borks
+  the freelist).

 - Bump MAXSESSION to 60K.
 - 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.
