Alan Somers 4312aa67e3 tests/sys/netinet/fibs_test: skip selected tests when firewalls are enabled
Some tests send packets over epair(4) interfaces. Firewalls can cause

Alan Somers 5a33a2afb3 Fix back-to-back runs of sys/netinet/fibs_test;slaac_on_nondefault_fib6
This test was failing if run twice because rtadvd takes too long to die.
The rtadvd process from the first run was still running when the
second run created its interfaces.  The solution is to use SIGKILL during
the cleanup instead of SIGTERM so rtadvd will die faster.

While I'm here, randomize the addresses used for the test, which makes bugs
like this easier to spot, and fix the cleanup order to be the opposite of
the setup order

Alan Somers 559b42968c Constrain IPv6 routes to single FIBs when net.add_addr_allfibs=0
sys/netinet6/icmp6.c
	Use the interface's FIB for source address selection in ICMPv6 error
	responses.

sys/netinet6/in6.c
	In in6_newaddrmsg, announce arrival of local addresses on the
	interface's FIB only.  In in6_lltable_rtcheck, use a per-fib ND6
	cache instead of a single cache.

sys/netinet6/in6_src.c
	In in6_selectsrc, use the caller's fib instead of the default fib.
	In in6_selectsrc_socket, remove a superfluous check.

sys/netinet6/nd6.c
	In nd6_lle_event, use the interface's fib for routing socket
	messages.  In nd6_is_new_addr_neighbor, check all FIBs when trying
	to determine whether an address is a neighbor.  Also, simplify the
	code for point to point interfaces.

sys/netinet6/nd6.h
sys/netinet6/nd6.c
sys/netinet6/nd6_rtr.c
	Make defrouter_select fib-aware, and make all of its callers pass in
	the interface fib.

sys/netinet6/nd6_nbr.c
	When inputting a Neighbor Solicitation packet, consider the
	interface fib instead of the default fib for DAD.  Output NS and
	Neighbor Advertisement packets on the correct fib.

sys/netinet6/nd6_rtr.c
	Allow installing the same host route on different interfaces in
	different FIBs.  If rt_add_addr_allfibs=0, only install or delete
	the prefix route on the interface fib.

tests/sys/netinet/fibs_test.sh
	Clear some expected failures, but add a skip for the newly revealed
	BUG217871.

Julio Merino 8e79f15196 Make cleanup routines idempotent
cleanup routines can be executed at any point during the execution of the
body, including even before the body has done any real work.  In those
cases, cleanup routines should be careful to not raise spurious errors so
as to not "override" the actual result of the test case.

This is just general good coding style but is not a problem in practice
for these specific tests.  (The way I discovered the issue, though, was
due to a regression I introduced in Kyua itself while refactoring some
internals.)

	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.

Alan Somers 7278b62aee 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.

Alan Somers 0cfee0c223 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.

Alan Somers 0489b8916e 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.

Alan Somers 743c072a09 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.
