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.

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.
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 !
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.
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)
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.

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).

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.

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)

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.
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
should be enough), but without it, the default route update under
OpenBSD will fail.
