3dabcca7c9 MFC r274267:
Use PROGS instead of PROG and remove unnecessary SRCS?= assignment

  Using PROG instead of PROGS will in cases of high -j with -DNO_ROOT cause
  the PROG to show up more than once as it's handling the SCRIPTS install case
  in a recursive manner, separate from the non-recursive case

  After the recent batch of commits to bsd.progs.mk to fix behavior with how
  variables are defaulted to, explicitly setting SRCS for a PROG is no longer
  required

ea95859a3e MFC changes related to PR kern/189089. Unlike CURRENT, stable/10 does not
panic when you attempt to remove the IP address.  But it still fails to
remove the address.

MFC r265094

Add regression test for PR kern/189088.

MFC r265092

Fix a panic when removing an IP address from an interface, if the same
address exists on another interface.  The panic was introduced by change
264887, which changed the fibnum parameter in the call to rtalloc1_fib() in
ifa_switch_loopback_route() from RT_DEFAULT_FIB to RT_ALL_FIBS.  The
solution is to use the interface fib in that call.  For the majority of
users, that will be equivalent to the legacy behavior.

Fix host and network routes for new interfaces when net.add_addr_allfibs=0

sys/net/route.c
        In rtinit1, use the interface fib instead of the process fib.  The
        latter wasn't very useful because ifconfig(8) is usually invoked
        with the default process fib.  Changing ifconfig(8) to use setfib(2)
        would be redundant, because it already sets the interface fib.

6142905fe1 MFC changes relating to running multiple interfaces on different fibs but
with addresses on the same subnet.

MFC r266860

Fix unintended KBI change from r264905.  Add _fib versions of
ifa_ifwithnet() and ifa_ifwithdstaddr()  The legacy functions will call the
_fib() versions with RT_ALL_FIBS, preserving legacy behavior.

sys/net/if_var.h
sys/net/if.c
        Add legacy-compatible functions as described above.  Ensure legacy
        behavior when RT_ALL_FIBS is passed as fibnum.

        legacy functions otherwise.

tests/sys/netinet/fibs_test.sh
tests/sys/netinet/udp_dontroute.c
        Improve the udp_dontroute test.  The bug that this test exercises is
        that ifa_ifwithnet() will return the wrong address, if multiple
        interfaces have addresses on the same subnet but with different
        fibs.  The previous version of the test only considered one possible
        failure mode: that ifa_ifwithnet_fib() might fail to find any
        suitable address at all.  The new version also checks whether
        ifa_ifwithnet_fib() finds the correct address by checking where the
        ARP request goes.

MFC r264917

Style fixes, mostly trailing whitespace elimination.  No functional change.

MFC r264905

Fix subnet and default routes on different FIBs on the same subnet.

These two bugs are closely related.  The root cause is that ifa_ifwithnet
does not consider FIBs when searching for an interface address.

sys/net/if_var.h
sys/net/if.c
        Add a fib argument to ifa_ifwithnet and ifa_ifwithdstadddr.  Those
        functions will only return an address whose interface fib equals the
        argument.

sys/net/route.c
        Update calls to ifa_ifwithnet and ifa_ifwithdstaddr with fib
        arguments.

sys/netinet/in.c
        Update in_addprefix to consider the interface fib when adding
        prefixes.  This will prevent it from not adding a subnet route when
        one already exists on a different fib.

sys/net/rtsock.c
sys/netinet/in_pcb.c
sys/netinet/ip_output.c
sys/netinet/ip_options.c
sys/netinet6/nd6.c
        Add RT_DEFAULT_FIB arguments to ifa_ifwithdstaddr and ifa_ifwithnet.
        In some cases it there wasn't a clear specific fib number to use.
        In others, I was unable to test those functions so I chose
        RT_DEFAULT_FIB to minimize divergence from current behavior.  I will
        fix some of the latter changes along with PR kern/187553.

tests/sys/netinet/fibs_test.sh
tests/sys/netinet/udp_dontroute.c
tests/sys/netinet/Makefile
        Revert r263738.  The udp_dontroute test was right all along.
        However, bugs kern/187550 and kern/187553 cancelled each other out
        when it came to this test.  Because of kern/187553, ifa_ifwithnet
        searched the default fib instead of the requested one, but because
        of kern/187550, there was an applicable subnet route on the default
        fib.  The new test added in r263738 doesn't work right, however.  I
        can verify with dtrace that ifa_ifwithnet returned the wrong address
        before I applied this commit, but route(8) miraculously found the
        correct interface to use anyway.  I don't know how.

        Clear expected failure messages for kern/187550 and kern/187552.

MFC r263738

tests/sys/netinet/Makefile
tests/sys/netinet/fibs.sh
        Replace fibs:udp_dontroute with fibs:src_addr_selection_by_subnet.
        The original test was poorly written; it was actually testing
        kern/167947 instead of the desired kern/187553.  The root cause of the
        bug is that ifa_ifwithnet did not have a fib argument.  The new test
        more directly targets that behavior.

bb616da931 MFC r263779
Correct ARP update handling when the routes for network interfaces are
restricted to a single FIB in a multifib system.

Restricting an interface's routes to the FIB to which it is assigned (by
setting net.add_addr_allfibs=0) causes ARP updates to fail with "arpresolve:
can't allocate llinfo for x.x.x.x".  This is due to the ARP update code hard
coding it's lookup for existing routing entries to FIB 0.

sys/netinet/in.c:
	When dealing with RTM_ADD (add route) requests for an interface, use
	the interface's assigned FIB instead of the default (FIB 0).

sys/netinet/if_ether.c:
	In arpresolve(), enhance error message generated when an
	lla_lookup() fails so that the interface causing the error is
	visible in logs.

tests/sys/netinet/fibs_test.sh
	Clear ATF expected error.

melifaro, we agreed that ifconfig's behavior was not a bug.  The main

resolved kern/187549 in a different way instead.

Replace 4.4BSD Lite's unix domain socket backpressure hack with a cleaner
mechanism, based on the new SB_STOP sockbuf flag.  The old hack dynamically
changed the sending sockbuf's high water mark whenever adding or removing
data from the receiving sockbuf.  It worked for stream sockets, but it never
worked for SOCK_SEQPACKET sockets because of their atomic nature.  If the
sockbuf was partially full, it might return EMSGSIZE instead of blocking.

The new solution is based on DragonFlyBSD's fix from commit
3a6117bbe0ed6a87605c1e43e12a1438d8844380 on 2008-05-27.  It adds an SB_STOP
flag to sockbufs.  Whenever uipc_send surpasses the socket's size limit, it
sets SB_STOP on the sending sockbuf.  sbspace() will then return 0 for that
sockbuf, causing sosend_generic and friends to block.  uipc_rcvd will
likewise clear SB_STOP.  There are two fringe benefits: uipc_{send,rcvd} no
longer need to call chgsbsize() on every send and receive because they don't
change the sockbuf's high water mark.  Also, uipc_sense no longer needs to
acquire the UIPC linkage lock, because it's simpler to compute the
st_blksizes.

There is one drawback: since sbspace() will only ever return 0 or the
maximum, sosend_generic will allow the sockbuf to exceed its nominal maximum
size by at most one packet of size less than the max.  I don't think that's
a serious problem.  In fact, I'm not even positive that FreeBSD guarantees a
socket will always stay within its nominal size limit.

sys/sys/sockbuf.h
	Add the SB_STOP flag and adjust sbspace()

sys/sys/unpcb.h
	Delete the obsolete unp_cc and unp_mbcnt fields from struct unpcb.

sys/kern/uipc_usrreq.c
	Adjust uipc_rcvd, uipc_send, and uipc_sense to use the SB_STOP
	backpressure mechanism.  Removing obsolete unpcb fields from
	db_show_unpcb.

	Clear expected failures from ATF.

Fix PR kern/185813 "SOCK_SEQPACKET AF_UNIX sockets with asymmetrical buffers
drop packets".  It was caused by a check for the space available in a
sockbuf, but it was checking the wrong sockbuf.

sys/sys/sockbuf.h
sys/kern/uipc_sockbuf.c
	Add sbappendaddr_nospacecheck_locked(), which is just like
	sbappendaddr_locked but doesn't validate the receiving socket's space.
	Factor out common code into sbappendaddr_locked_internal().  We
	shouldn't simply make sbappendaddr_locked check the space and then call
	sbappendaddr_nospacecheck_locked, because that would cause the O(n)
	function m_length to be called twice.

sys/kern/uipc_usrreq.c
	Use sbappendaddr_nospacecheck_locked for SOCK_SEQPACKET sockets,
	because the receiving sockbuf's size limit is irrelevant.

tests/sys/kern/unix_seqpacket_test.c
	Now that 185813 is fixed, pipe_128k_8k fails intermittently due to
	185812.  Make it fail every time by adding a usleep after starting the
	writer thread and before starting the reader thread in test_pipe.  That
	gives the writer time to fill up its send buffer.  Also, clear the
	expected failure message due to 185813.  It actually said "185812", but
	that was a typo.
