11f9e243a2 Since ppp.link{up,down} is invoked at the end of IPCP negotiation, if
we need ppp.link{up,down}, we couldn't disable IPCP.  Now, if IPCP is
disabled, ppp.link{up,down} is invoked at the end of IPV6CP
negotiation.

6ceeb6902a utmp.ut_time and lastlog.ll_time are explicitly int32_t rather than
time_t.  Deal with the possibility that time_t != int32_t.  This boils
down to this sort of thing:
 -   time(&ut.ut_time);
 +   ut.ut_time = time(NULL);
and similar for ctime(3) etc.  I've kept it minimal for the stuff
that may need to be portable (or 3rd party code), but used Matt's time32
stuff for cases where that isn't as much of a concern.

Objected to by: Andre Oppermann <oppermann@pipeline.ch>

After Andre's objection, I've re-examined rfc 2759 and noted that it
says that the domain name shouldn't be used when generating the
NT-Response field.  So it looks like the bug is in freeradius rather
than in ppp.

250be50b72 Compensate for dodgy Win98/WinME MSCHAPv2 responses later in the code
path... after we've talked to any RADIUS servers involved, so that we
haven't touched the data before it gets to the server.

Make it clearer in the code that this compensation is done by setting
a flag to a value of zero, a flag which rfc2759 says *MUST* be zero.

While we're here, don't bother passing the peer challenge into
radius_Authenticate().  It's already part of the key we're passing in
(this becomes obvious now that I've structured that data...).

This ``fix'' doesn't help to authenticate Win98/WinME users in my test
environment as ports/net/freeradius seems to ignore the flag
completely anyway, but it may help with other RADIUS servers.

8fb5ef5ae2 Understand the following Microsoft Vendor Specific RADIUS attributes:
RAD_MICROSOFT_MS_MPPE_ENCRYPTION_POLICY
  RAD_MICROSOFT_MS_MPPE_ENCRYPTION_TYPES
  RAD_MICROSOFT_MS_MPPE_RECV_KEY
  RAD_MICROSOFT_MS_MPPE_SEND_KEY

These attributes may be supplied by a RADIUS server when MSCHAPv2 is
used to authenticate.

It *should* now be possible to build ppp with -DNODES and still support
CHAP/MSCHAP/MSCHAPv2/MPPE via a RADIUS server, but the code isn't yet
smart enough to do that (building with -DNODES just looses these
facilities).

aadbb4eab1 Don't send a RAD_NAS_IP_ADDRESS attribute as RAD_NAS_IDENTIFIER is
sufficient.

In fact, using both breaks the radiator RADIUS daemon when used with
a db as it maps both attributes to the same field value and then
fails the insert.

I decided to remove RAD_NAS_IP_ADDRESS on the basis that rfc2138 says:

      An Access-Request MUST contain a User-Name attribute.  It SHOULD
      contain either a NAS-IP-Address attribute or NAS-Identifier
      attribute (or both, although that is not recommended).  It MUST

despite the fact that this not recommended bit was removed from the
updated rfc.

de59e178aa o Clean up some #includes
o Bump version number to 3.0.4
o When talking to a RADIUS server, provide a NAS-Port-Type.

  When the NAS-Port-Type is Ethernet, provide a NAS-Port value equal
  to the SESSIONID from the environment in direct mode or the
  NGM_PPPOE_SESSIONID message in other modes.  If no SESSIONID is found,
  default to the interface index in client mode or zero in server mode.

  When the NAS-Port-Type is ISDN, set the NAS-Port to the minor number
  of the physical device (ie, the N in /dev/i4brbchN).

  This makes it easier for the RADIUS server to identify the client
  WRT accounting data etc.

c4a913b6b8 Don't provide an RTA_GATEWAY sockaddr when we write RTM_CHANGE messages
to the routing socket.

The local address on a point-to-point interface is not actually a
gateway address - despite it appearing in the second column of
netstat -r's output.  Providing a gateway to an RTM_CHANGE will
currently change the route's interface so that it's using the
specified gateway - not what we want.

361a7b933f When writing messages to the routing socket, round sockaddr sizes
up in the same way that we expect them to be when we read them.

This is a no-op on i386 and probably on alphas, as we currently
only support AF_INET and AF_INET6.

a3d71c3de1 Be paranoid about non-zero netmasks being associated with INET addresses
of 0.0.0.0.

The OpenBSD PF_ROUTE/NET_RT_DUMP sysctl is sending back routes with
RTAX_NETMASK set, but the corresponding sockaddr being 4 zero bytes
(with an address family of zero).  ppp was getting confused by this
and ending up interpreting it as a 0.0.0.0/32 routing table
destination and subsequently failing to do anything with the route.

Specifically, after this fix, ppp under OpenBSD can successfully
change and delete the default route again !

26dceef0a6 Don't adjust_linklocal() when pulling a sockaddr out of an ncpaddr or
ncprange structure.

Don't write() the netmask for IPv6 sockaddrs to the routing socket if
the prefixlen is 128.

It seems that messages written to the routing socket with the scopeid
set for link local addresses are not understood.  Instead, we have to
put the scopeid in the 5th and 6th bytes of the address (see
adjust_linklocal() in ncpaddr.c).  I think this may be a bug in the
KAME implementation - it should really understand both forms.

dad51e5ce8 Don't avoid setting a 0 second timer in datalink_StartDialTimer() by
not setting any timer.  Instead, set a 1 millisecond timer.

This ensures that ppp will come out of it's select() call after
losing carrier in -ddial mode with a reconnect period of 0 and
going to ST_OPENING, rather than waiting indefinitely for some
other event to wake ppp up.

2a772845ff When the peer fails to specify an MRU and a 1500 byte MRU is not
allowed either because of the transport or configuration, send a
MRU NAK only once, then allow the negotiations to proceed.

rfc1661 says that 1500 should always be allowed and rfc2516 says
that 1492 is the maximum for PPPoE.  This changes ppp so that it
only weakly suggests 1492, then goes with the default (leaving
the problem in the hands of the peer WRT how they set their MTU).

2bc21ed985 Hopefully improve control message passing over Unix domain sockets.
1) Allow the sending of more than one control message at a time
over a unix domain socket. This should cover the PR 29499.

2) This requires that unp_{ex,in}ternalize and unp_scan understand
mbufs with more than one control message at a time.

3) Internalize and externalize used to work on the mbuf in-place.
This made life quite complicated and the code for sizeof(int) <
sizeof(file *) could end up doing the wrong thing. The patch always
create a new mbuf/cluster now. This resulted in the change of the
prototype for the domain externalise function.

4) You can now send SCM_TIMESTAMP messages.

5) Always use CMSG_DATA(cm) to determine the start where the data
in unp_{ex,in}ternalize. It was using ((struct cmsghdr *)cm + 1)
in some places, which gives the wrong alignment on the alpha.
(NetBSD made this fix some time ago).

This results in an ABI change for discriptor passing and creds
passing on the alpha. (Probably on the IA64 and Spare ports too).

6) Fix userland programs to use CMSG_* macros too.

7) Be more careful about freeing mbufs containing (file *)s.
This is made possible by the prototype change of externalise.

1136c6ac64 Back out the previous fix to deal with kernels that don't support IPv6,
and implement a far more subtle and correct fix.

The reason behind the infinite loop was that ppp was trying to make up
initial IPv6 numbers and wasn't giving up when it failed unexpectedly to
assign the addresses it just fabricated to it's interface (thinking that
the reason was because another interface was using the same address).
It now attempts this up to 100 times before just failing and trying to
muddle along (in reality, this should never happen more than a couple
of times unless our random number generator doesn't work).

Also, when IPv6 is not available, don't even try to assign the IPv6
interface address in the first place...

IMHO this shouldn't be necessary (the destination & mask/prefixlen

OpenBSD will fail.
