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.

0ed9882caa Remove the hack that ensures that rt_Update() works on FreeBSD. Now
that the ncpaddr code doesn't create default routes with non-zero
masks, everything works as it should.

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.

46df5aa7bc Add a ``log'' command for logging specific information.
Add an ``UPTIME'' variable to indicate the bundle uptime.

It's now possible to put something like this in ppp.linkdown
for a server setup:

  MYADDR:
    log Session closing: User USER, address HISADDR, up UPTIME

Fixed some memory leakage with commands that expand words.
Made some functions static.
Fixed a diagnostic bug (iface add .... SIOCDIFADDR)

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.

Bump the ppp version number to indicate the event.

0407540adf ia64 support. Due to the bogus placement of some i4b includes, it is

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.

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.

d42d9220c7 When attempting to change the default route, don't write the gateway
and mask to the routing socket, otherwise the update fails.

Warning provided by: markm

The code here was broken for FreeBSD when IPv6 support was added, but
was fixed for OpenBSD.  OpenBSD expects the gateway and mask to be
supplied and fails the update otherwise.

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...

5ae083292b Specify the gateway address when updating the MTU and send/recv pipe
sizes on a route.

IMHO this shouldn't be necessary (the destination & mask/prefixlen
should be enough), but without it, the default route update under
OpenBSD will fail.
