56e0670fdc Correct a very old error in both vm_object_madvise() (originating in 
vm/vm_object.c revision 1.88) and vm_object_sync() (originating in
vm/vm_map.c revision 1.36): When descending a chain of backing objects,
both use the wrong object's backing offset.  Consequently, both may
operate on the wrong pages.

Quoting Matt, "This could be responsible for all of the sporatic madvise
oddness that has been reported over the years."

a4eb4405e3 Disallow a particular kind of port theft described by the following scenario: 
Alice is too lazy to write a server application in PF-independent
	manner.  Therefore she knocks up the server using PF_INET6 only
	and allows the IPv6 socket to accept mapped IPv4 as well.  An evil
	hacker known on IRC as cheshire_cat has an account in the same
	system.  He starts a process listening on the same port as used
	by Alice's server, but in PF_INET.  As a consequence, cheshire_cat
	will distract all IPv4 traffic supposed to go to Alice's server.

Such sort of port theft was initially enabled by copying the code that
implemented the RFC 2553 semantics on IPv4/6 sockets (see inet6(4)) for
the implied case of the same owner for both connections.  After this
change, the above scenario will be impossible.  In the same setting,
the user who attempts to start his server last will get EADDRINUSE.

Of course, using IPv4 mapped to IPv6 leads to security complications
in the first place, but there is no reason to make it even more unsafe.

This change doesn't apply to KAME since it affects a FreeBSD-specific
part of the code.  It doesn't modify the out-of-box behaviour of the
TCP/IP stack either as long as mapping IPv4 to IPv6 is off by default.

f082437d56 Remove (at least temporarily) the check that prevents us from including 
this file from userland.  Since we export struct ifnet to userland, and
that struct ifnet now contains a struct task, userland needs to know
what struct task looks like.

We need to consider having a pointer to a struct task here instead and
forward declare struct task in the !_KERNEL case.
