  POSIX-required ntohl() family of functions.
o Do similar things to expose the ntohl() family in libstand, <netinet/in.h>,
  and <sys/param.h>.
o Prepend underscores to the ntohl() family to help deal with
  complexities associated with having MD (asm and inline) versions, and
  having to prevent exposure of these functions in other headers that
  happen to make use of endian-specific defines.
o Create weak aliases to the canonical function name to help deal with
  third-party software forgetting to include an appropriate header.
o Remove some now unneeded pollution from <sys/types.h>.
o Add missing <arpa/inet.h> includes in userland.

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

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.

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...

  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.

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).

5e3b2d6847 If the peer sends a REQ without the IPADDR option, only reject it
once.  If they repeat the request (again without the IPADDR option)
ACK it.

I've had reports that some ppp implementations will not assign
themselves an IP number.  This should negotiate with such things.

6301d506fb Reduce the interface MTU by 2 when MPPE has been successfully negotiated.
This is necessary because MPPE will combine the protocol id with the
payload received on the tun interface, encrypt it, then prepend its

6cf6ee7625 Add support for stateful MPPE (microsoft encryption) providing
encryption compatibility with Windows 2000.  Stateful encryption
uses less CPU but is bad on lossy transports.

The ``set mppe'' command has been expanded.  If it's used with any
arguments, ppp will insist on encryption, closing LCP if the other
end refuses.

Unfortunately, Microsoft have abused the CCP reset request so that
receiving a reset request does not result in a reset ack when using
MPPE...

0272404f73 Handle situations where we've already got a P2P interface address
of a/x -> b and then negotiate a/x -> c by simply expecting SIOCAIFADDR
to do the change.

This was broken by the last commit that optimised out the deletion and
re-addition of the same a/x -> b combination, and forgot to compare
the old/new destination addresses.

Conveniently enough, this problem didn't effect setups where the
default route goes via the ppp link, and most other setups don't
care what the the destination address is actually set to.  It broke
test environments where ppp connects to the local machine rather
badly though....

7f89db65f5 Add a ``Usable'' function to the ccp switch. The function
is called prior to sending a CCP configure request for a
given protocol.  The default is to send the request, but
this is overridden for MPPE which checks to see if the lcp
negotiations agreed CHAP81, and if not fails.

Use the same function to decide if we should reject peer
requests for MPPE.

This should get rid of those boring messages about not being
able to initialise MPPE when we don't negotiate CHAP81.

542962ddf9 Introduce another global (MPPE_IsServer) so that we initiate the
MPPE session keys correctly.

I'm a bit dubious about this code.  It seems that the session keys
are initialised differently based on whether you're the client or
the server.  One side is the server if it issues the first challenge,
but of course you can issue a challenge from both sides.... at the
same time.  Sounds like another wonderful M$ assumption...
