Brian Somers a95b23a6b2 Don't forget to process the Ident field on the front of
RAD_MICROSOFT_MS_CHAP_ERROR and RAD_MICROSOFT_MS_CHAP2_SUCCESS
messages, and remove the hack in chap.c to ignore that ident field
on the client side.

This anomoly was hacked around during development, and I forgot to
go back and fix it properly.

Brian Somers 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).

Brian Somers 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.

Brian Somers 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.

The local address on a point-to-point interface is not actually a

currently change the route's interface so that it's using the

Brian Somers 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 !

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.

David Malone 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.

Brian Somers f0ea3513c9 Some cosmetic changes to sync with OpenBSD 2001-08-27 19:08:43 +00:00
Brian Somers a7428f1858 Send a reset request for every packet received when our encryption
dictionaries are out of sync.

This avoids the complications that happen when our original reset
request gets lost in transit (quite likely in hind sight, given a
lossy link) when we end up ignoring the peer for the next (up to)
256 packets.

Brian Somers 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...

  It's now possible to manage IPv6 interface addresses and routing

  not.

  IPV6CP support is crude for now, and hasn't been tested against
  any other implementations.

  RADIUS and IPv6 are independent of eachother for now.

  ppp.linkup/ppp.linkdown aren't currently used by IPV6CP

o Understand all protocols(5) in filter rules rather than only a select
  few.

o Allow a mask specification for the ``delete'' command.  It's now
  possible to specifically delete one of two conflicting routes.

o When creating and deleting proxy arp entries, do it for all IPv4
  interface addresses rather than doing it just for the ``current''
  peer address.

o When iface-alias isn't in effect, don't blow away manually (via ``iface
  add'') added interface addresses.

o When listening on a tcp server (diagnostic) socket, bind so that a
  tcp46 socket is created -- allowing both IPv4 and IPv6 connections.

o When displaying ICMP traffic, don't display the icmp type twice.
  When display traffic, display at least some information about unrecognised
  traffic.

o Bump version

Brian Somers 5a0827311e If the peer REJects our MRU REQ, stop REQing it -- *EVEN* if we're
doing PPPoE and the default MRU is therefore too big.

When negotiating with win2k, we ask for MRU 1492 and the win2k box
NAKs us saying ``MRU 1492''.  This doesn't make sense to me.  When
we continue to request MRU 1492, the win2k box eventually REJs our
MRU.  This fix allows negotiations to continue at that point,
bringing the link up and potentially allowing the win2k box to send
us frames that are too large.  AFAICT this is better than failing
to bring the link up.... probably !

I have no idea how to do the equivalent of ``route get'' or
``ifconfig -a'' under win2k, so I can't tell what MTU it actually
ends up using.

I believe the bug is in win2k (it's certainly mis-negotiating).

Roger Hardiman e3771825e4 Allow LQR periods of 1 second and FSM retry periods of 1 second. This allows us
to run PPP over Radiocontact T-Link Radio Modems which run best when something
is transmitted at least every 1.5 seconds.

Ruslan Ermilov 036f8336fa mdoc(7) police: replace two -unfilled displays with -tag lists.
This works only because of bugs in current implementation: the
first .It after ``.Bd -unfilled'' re-enables filling mode and
does not restore (disable) it back afterwards.
