550: connections (so it is easier to configure);</li>
551: </ul>

637: packets for closing links are sent, new connections
638: aren't accepted during shutdown.</li>
639: <li> Fixed races in filling of RADIUS packets. In particular,
640: RAD_NAS_PORT value in the RADIUS could be wrong.</li>

707: </p>
708: <p>Changes since version 3 (most of this work was sponsored by
709: <A href="http://www.surfnet.nl/">http://www.surfnet.nl/</A>):
710: <ul>
711: <li>Design changes:
712: Mpd uses now a thread-based event system using libpdel, these libpdel parts are now
713: integrated:
714: <ul>
715: <li>typed_mem(3)</li>
716: <li>pevent(3)</li>
717: <li>alog(3)</li>
718: </ul>
719:
720: Mpd uses a "Giant Mutex" for protecting its resources.</li>
721: <li>Major new features:
722: <ul>
723: <li>Implemented the Extensible Authentication Protocol RFC 2284 (EAP). Currently only
724: EAP-MD5 is supported (client and server side).
725: EAP negotiaton can be enabled at link level.</li>
726: <li>Implemented OPIE (One-time Passwords In Everything).</li>
727: <li>Implemented authentication against systems password database <code>master.passwd</code>.</li>
728: <li>utmp/wtmp logging.</li>
729: </ul>
730: </li>
731: <li>Rewrites of the authentication subsystem:
732: <ul>
733: <li>Make authentication and accounting requests asynchronous using paction(3).</li>
734: <li>Authentication backends are acting now independently from the rest of Mpd, using
735: some internal structs as interface.</li>
736: <li>The <code>mpd.secret</code> file is now used as one authentication backends of many, it
737: has no special role anymore, i.e. it could be disabled.</li>
738: <li>Generate a session-id at bundle and link level for using with accounting requests.</li>
739: </ul>
740: </li>
741: <li>RADIUS related changes:
742: <ul>
743: <li><b>IMPORTANT</b>: Mpd needs now an enhanced libradius, here are the patchsets:
744: <code><A href="http://www.bretterklieber.com/freebsd/libradius.diff">http://www.bretterklieber.com/freebsd/libradius.diff</A></code>
745: <code><A href="http://www.bretterklieber.com/freebsd/libradius5.diff">http://www.bretterklieber.com/freebsd/libradius5.diff</A></code></li>
746: <li>Remember and send the RAD_STATE attribute.</li>
747: <li>Message-Authenticator support.</li>
748: <li>EAP Proxy Support.</li>
749: </ul>
750: </li>
751: <li>Added a new option for PPTP links for disabling the windowing mechanism
752: specified by the protocol. Disabling this will cause Mpd to violate
753: the protocol, possibly confusing other PPTP peers, but often results
754: in better performance. The windowing mechanism is a design error in
755: the PPTP protocol; L2TP, the successor to PPTP, removes it. You need
756: a recent version of FreeBSD (NGM_PPTPGRE_COOKIE >= 1082548365) in order
757: to get this feature.<br>
758: <code>set pptp disable windowing</code></li>
759: <li>Added a new commandline option <code>-t</code> for adding ng_tee into the netgraph.<br>
760: Submitted by: Gleb Smirnoff, glebius at cell dot sick dot ru</li>
761: <li>Removed configuration parameters:
762: <ul>
763: <li>bundle: <code>radius-fallback</code></li>
764: <li>iface: <code>radius-session</code>, <code>radius-idle</code>, <code>radius-mtu</code>,
765: <code>radius-route</code>, <code>radius-acl</code></li>
766: <li>ipcp: <code>radius-ip</code></li>
767: </ul>
768:
769:
770: Moved configuration parameters:
771: <ul>
772: <li>bundle to auth: <code>radius-auth</code>, <code>radius-acct</code>, <code>authname</code>,
773: <code>password</code>, <code>max-logins</code></li>
774: <li>radius to auth: <code>acct-update</code></li>
775: <li>ccp to auth: <code>radius</code> and renamed to <code>mppc-pol</code></li>
776: </ul>
777:
778:
779: New configuration parameters:
780: <ul>
781: <li>link: <code>keep-ms-domain</code>, this prevents Mpd from stripping the MS-Domain,
782: this is can be useful when using IAS as RADIUS server.</li>
783: <li>radius: <code>message-authentic</code>, this adds the Message-Authenticator
784: attribute to the RADIUS request.</li>
785: <li>auth: <code>internal</code>, controles the usage of the <code>mpd.secret</code> file
786: (internal authentication backend).</li>
787: <li>auth: <code>opie</code>, enables/disables the OPIE authentication backend.</li>
788: <li>auth: <code>system</code>, enables/disables authentication against systems password
789: database.</li>
790: <li>auth: <code>utmp-wtmp</code>, enables/disables utmp/wtmp logging.
791: database.</li>
792: <li>auth: <code>timeout</code>, configureable timeout for the authentication phase.</li>
793: <li>eap: <code>radius-proxy</code>, this causes Mpd to proxy all EAP requests to
794: the RADIUS server, Mpd only makes the initial Identity-Request
795: (this saves one round-trip), every other requests are forwarded to the RADIUS server.
796: This adds the possibility supporting every EAP-Type of the RADIUS server, without
797: implementing each EAP-Type into Mpd.</li>
798: <li>eap: <code>md5</code>, EAP-Type MD5, it's the same as CHAP-MD5, but inside EAP frames.</li>
799: </ul>
800: </li>
801: <li>Removed defines <code>ENCRYPTION_MPPE</code> and <code>COMPRESSION_MPPC</code>, they are now built in.</li>
802: <li>Get rid of <code>IA_CUSTOM</code> define.</li>
803: <li>BugFix: Fixed a mem-leak in the pptp-ctrl stuff.</li>
804: </ul>
