o Redesign the layering mechanism and make the aliasing code part of the layering. We now ``stack'' layers as soon as we open the device (when we figure out what we're dealing with). A static set of `dispatch' routines are also declared for dealing with incoming packets after they've been `pulled' up through the stacked layers. Physical devices are now assigned handlers based on the device type when they're opened. For the moment there are three device types; ttys, execs and tcps. o Increment version number to 2.2 o Make an entry in [uw]tmp for non-tty -direct invocations (after pap/chap authentication). o Make throughput counters quad_t's o Account for the absolute number of mbuf malloc()s and free()s in ``show mem''. o ``show modem'' becomes ``show physical''.

Add support for the Evil Microsoft ppp extentions. Yes, they did it on their own without even attempting to get concensus in the IETF, but there are also lots of Win95/NT boxes out there. CLoses PR#1494 Submitted-By: Peter Childs <pjchilds@imforei.apana.org.au>

Support client side DNS server negotiation, disabled and denied by default (POLA). o Remove ``enable'' msext. Now, doing a ``set nbns'' will automatically enable a NBNS ACK/NAK rather than a REJ. o Add accept|disable|deny|enable dns. If we ``accept'', we'll tell the peer what our nameservers are (if he asks). The values in resolv.conf can be overridden with the ``set dns'' command. If we ``enable'', we'll REQ using our resolv.conf entries, and any NAKs are written back to resolv.conf. o Remove ``show msext'' and show the relevent IP numbers in ``show ipcp''.

Create `struct sticky_route'. Any `add' or `delete' command that uses MYADDR or HISADDR will be added to the sticky route list (show ipcp). When MYADDR or HISADDR change due to IPCP negotiations, and if `sroutes' is enabled (the default), all sticky route entries are updated in the routing table. The end result is that `add default hisaddr' will ``stick'', as will ``add myaddr 255.255.255.255 127.0.0.1'' and ``add 1.2.3.4 255.255.255.0 hisaddr''.

struct ipcp {
Move the global FSMs into their relevent structures. IPCP, CCP and LCP are now just derived FSMs. Comment each of the FSM implementations so that we can tell what's going on. Revise the state transitions so that CCP and IPCP actually send terminate REQs when appropriate. The OS & IPCP layers are still like spagetti (next job).

o Move the accept/deny/disable/enable globals either to the bundle (non-negotiated vars) or to their respective IPCP, LCP or CCP. o Enable rolling throughput statistics by default. o Remove the `display' command. These values now appear in `show bundle', `show ipcp', `show ccp' and `show lcp'. o Initialise auth name & key at bundle create time (oops). o Rename pppd-deflate (the id-24 hack) to deflate24. o Don't send both a REJ and a NAK to an IPCP or LCP REQ. Favour the REJ (already done at the CCP level). o Recurse in datalink_UpdateSet() when we change state, otherwise we end up setting no descriptors and getting jammed in the imminent select() instead of doing the dial/login/hangup. o Display our CHAP encryption method despite being built with DES. o Display VJ as not negotiated in ``show ipcp'' when necessary.

struct in_range my_range; /* MYADDR spec */
Initial RADIUS support (using libradius). See the man page for details. Compiling with -DNORADIUS (the default for `release') removes support. TODO: The functionality in libradius::rad_send_request() needs to be supplied as a set of routines so that ppp doesn't have to wait indefinitely for the radius server(s). Instead, we need to get a descriptor back, select() on the descriptor, and ask libradius to service it when necessary. For now, ppp blocks SIGALRM while in rad_send_request(), so it misses PAP/CHAP retries & timeouts if they occur. Only PAP is functional. When CHAP is attempted, libradius complains that no User-Password has been specified... rfc2138 says that it *mustn't* be used for CHAP :-( Sponsored by: Internet Business Solutions Ltd., Switzerland

Allow control over the number of ConfigREQ & TermREQ attempts that are made in each of the FSMs (LCP, CCP & IPCP) and the number of REQs/Challenges for PAP/CHAP by accepting more arguments in the ``set {c,ip,l}cpretry'' and ``set {ch,p}apretry'' commands. Change the non-convergence thresholds to 3 times the number of configured REQ tries (rather than the previous fixed ``10''). We now notice repeated NAKs and REJs rather than just REQs. Don't suggest that CHAP 0x05 isn't supported when it's not configured. Fix some bugs that expose themselves with smaller numbers of retries: o Handle instantaneous disconnects (set device /dev/null) correctly by stopping all fsm timers in fsm2initial. o Don't forget to uu_unlock() devices that are files but are not ttys (set device /dev/zero). Fix a *HORRENDOUS* bug in RFC1661 (already fixed for an Open event in state ``Closed''): According to the state transition table, a RCR+ or RCR- received in the ``Stopped'' state are supposed to InitRestartCounter, SendConfigReq and SendConfig{Ack,Nak}. However, in ``Stopped'', we haven't yet done a TLS (or the last thing we did is a TLF). We must therefore do the TLS at this point ! This was never noticed before because LCP and CCP used not use LayerStart() for anything interesting, and IPCP tends to go into Stopped then get a Down because of an LCP RTR rather than getting a RCR again.
