609b7b269d Add a knob, WITH*_RPCBIND_WARMSTART_SUPPORT, to allow the end-user to build
rpcbind(8) with/without warmstart support.

The knob defaults to off to preserve POLA for the feature.

See rpcbind(8) for more details about the warmstart feature.

6ee7c85891 Bounds check rpcbs_rmtcall(..) to ensure rtype is less than RPCBVERS_STAT
Not returning if rtype == RPCBVERS_STAT will cause us to overrun the inf array, as
it's defined to be exactly RPCBVERS_STAT elements in rpcb_prot.x:

> include/rpc/rpcb_prot.x:typedef rpcb_stat rpcb_stat_byvers[RPCBVERS_STAT];

The proposed change also matches the rest of the rtype upper bound checks in the
file, so the original change was likely a typo.

In the event MK_INET6 != no in userspace, but is disabled in the

Skip over the IPv6 block to its respective cleanup with freeifaddrs if

430f7286a5 Merge ^/user/ngie/release-pkg-fix-tests to unbreak how test files are installed
after r298107

Summary of changes:

- Replace all instances of FILES/TESTS with ${PACKAGE}FILES. This ensures that
  namespacing is kept with FILES appropriately, and that this shouldn't need
  to be repeated if the namespace changes -- only the definition of PACKAGE
  needs to be changed
- Allow PACKAGE to be overridden by callers instead of forcing it to always be
  `tests`. In the event we get to the point where things can be split up
  enough in the base system, it would make more sense to group the tests
  with the blocks they're a part of, e.g. byacc with byacc-tests, etc
- Remove PACKAGE definitions where possible, i.e. where FILES wasn't used
  previously.
- Remove unnecessary TESTSPACKAGE definitions; this has been elided into
  bsd.tests.mk
- Remove unnecessary BINDIRs used previously with ${PACKAGE}FILES;
  ${PACKAGE}FILESDIR is now automatically defined in bsd.test.mk.
- Fix installation of files under data/ subdirectories in lib/libc/tests/hash
  and lib/libc/tests/net/getaddrinfo
- Remove unnecessary .include <bsd.own.mk>s (some opportunistic cleanup)

Document the proposed changes in share/examples/tests/tests/... via examples
so it's clear that ${PACKAGES}FILES is the suggested way forward in terms of
replacing FILES. share/mk/bsd.README didn't seem like the appropriate method
of communicating that info.

a85f12322c "source routing" in rpcbind
Fix a bug in rpcbind for multihomed hosts. If the server had interfaces on
two separate subnets, and a client on the first subnet contacted rpcbind at
the address on the second subnet, rpcbind would advertise addresses on the
first subnet. This is a bug, because it should prefer to advertise the
address where it was contacted. The requested service might be firewalled
off from the address on the first subnet, for example.

usr.sbin/rpcbind/check_bound.c
	If the address on which a request was received is known, pass that
	to addrmerge as the clnt_uaddr parameter. That is what addrmerge's
	comment indicates the parameter is supposed to mean. The previous
	behavior is that clnt_uaddr would contain the address from which the
	client sent the request.

usr.sbin/rpcbind/util.c
	Modify addrmerge to prefer to use an IP that is equal to clnt_uaddr,
	if one is found. Refactor the relevant portion of the function for
	clarity, and to reduce the number of ifdefs.

066c492a77 The Sun RPC framework uses a netbuf structure to represent the
transport specific form of a universal transport address.  The
structure is expected to be opaque to consumers.  In the current
implementation, the structure contains a pointer to a buffer
that holds the actual address.

In rpcbind(8), netbuf structures are copied directly, which would
result in two netbuf structures that reference to one shared
address buffer.  When one of the two netbuf structures is freed,
access to the other netbuf structure would result in an undefined
result that may crash the rpcbind(8) daemon.

Fix this by making a copy of the buffer that is going to be freed
instead of doing a shallow copy.
