Make external NFS clients know when files have their attributes changed and
avoid cache the file's state indefinitely. The va_filerev is what is sent
to the client as the "change" attribute, the client is periodically fetching
the attributes and without this option the attribute remains as some garbage

Account for the mapped pages in the kernel_pmap on x86 in
pmap_mapdev(). The pmap_unmapdev() on stable/9 calls pmap_remove() to
clear the range, which decrements kernel_pmap.pm_stats.resident_count.
Misaccounting causes miscellaneous failures, since pmap_remove() tests
the counter for zero and does nothing.
This is direct commit to stable/9, since HEAD and stable/10 use vmem
and do not utilize pmap_remove() etc.

rm -rf can fail sometimes with an error from fts_read. Make it
honor fflag to ignore fts_read errors, but stop deleting from
that directory because no further progress can be made.
When building a kernel with a high -j value on a high core count
machine, during the cleanobj phase we can wind up doing multiple
rm -rf at the same time for modules that have subdirectories. This
exposed this race (sometimes) as fts_read can return an error if
the directory is removed by another rm -rf. Since the intent of
the -f flag was to ignore errors, even if this was a bug in
fts_read, we should ignore the error like we've been instructed
to do.

Workaround for receiving Voice Calls using the E1750 dongle from
Huawei. It might appear as if the firmware is allocating memory blocks
according to the USB transfer size and if there is initially a lot of
data, like at the answering machine prompt, it simply dies without any
apparent reason. The simple workaround for this is to force a zero
length packet at hardware level after every 512 bytes of data. This
will force the other side to use smaller memory blocks aswell.
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.
MFC r264905 and r266860, except for the ATF parts.
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/rtsock.c
sys/netinet6/nd6.c
Call with _fib() functions if we must use a specific fib, or the
legacy functions otherwise.
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/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.
MFC r264887, except for the ATF test change. Also,
ifa_switch_loopback_route doesn't exist in stable/9, so the relevant change
to that function went into in_scrubprefix instead.
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.

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.
