It is no longer necessary to specify a -4/-6 flag on any ntp.conf
keyword. The address type is inferred from the address itself as
necessary. "restrict default" statements always apply to both address
families regardless of any -4/-6 flag that may be present.
So this change just tidies up our default config by removing the redundant
restrict -6 statement and comment, and by removing the -6 flag from the
restrict keyword that allows access from localhost.
This change was inspired by the patches provided in PRs 201803 and 210245,
and included some contrib/ntp code inspection to verify that the -4/-6
keywords are basically no-ops in all contexts now.

Normally pf rules are expected to do one of two things: pass the traffic or
block it. Blocking can be silent - "drop", or loud - "return", "return-rst",
"return-icmp". Yet there is a 3rd category of traffic passing through pf:
Packets matching a "pass" rule but when applying the rule fails. This happens
when redirection table is empty or when src node or state creation fails. Such
rules always fail silently without notifying the sender.
Allow users to configure this behaviour too, so that pf returns an error packet
in these cases.

When a "soft" mount is used for NFSv4.1, an RPC that fails without completing
will leave a slot in the NFSv4.1 session in an indeterminate state.
As such, all that can be done is free up the slot while making is no longer
usable.
A "soft" NFSv4.1 mount is not recommended in general, since it will leave
Open/Lock state in an indeterminate state. An exception is a pNFS mount of
a DS, since there are no Opens/Locks done for them except file creates
where loss of the Open state does not matter.
The patch also makes connections to DSs soft, so that they will fail when
a DS is non-functional or network partitioned, allowing the pNFS MDS to disable
the DS for a mirrored configuration.
This patch should not affect normal "hard" NFSv4.1 mounts.

When the NFSv4.1 pNFS client gets an error for a DS I/O operation using a
Flexible File layout, it returns the layout with an error.
This patch changes the code slightly, so that it returns the layout for all
errors except EACCES and lets the MDS decide what to do based on the error.
It also makes a couple of changes to nfscl_layoutrecall() to ensure that
the first layoutreturn(s) will have the error in the reply.
Plus, the patch adds a wakeup() so that the "nfscl" thread won't wait 1sec
before doing the LayoutReturn.
Tested against the pNFS service.
This patch should not affect non-pNFS use of the client.
The unused "dsp" argument will be used by a future patch that disables the
connection to the DS when possible.

For a pNFS MDS server, there must be mounts done to the DSs before the
nfsd is started. Adding the REQUIRE line makes sure these are done.
If there are NFS mounts in /etc/fstab that cannot be completed before
the nfsd starts, the "bg" mount option can still be used to handle that.
I do not believe this should cause problems for non-pNFS NFS servers.
(I have requested a review by rc@, but it is still pending.)
The changes made in r326573 required that messages always start with an
RFC 3164 timestamp. It looks like certain devices, but also certain
logging libraries (Python 3's "logging" package) simply don't generate
RFC 3164 formatted messages containing a timestamp.
Make timestamps optional again. When the timestamp is missing, also
assume that the message contains no hostname. The first word of the
message likely already belongs to the message payload.

This makes it possible, through src.conf(5) settings, to select which
LLVM targets you want to build during buildworld. The current list is:
* (WITH|WITHOUT)_LLVM_TARGET_AARCH64
* (WITH|WITHOUT)_LLVM_TARGET_ARM
* (WITH|WITHOUT)_LLVM_TARGET_MIPS
* (WITH|WITHOUT)_LLVM_TARGET_POWERPC
* (WITH|WITHOUT)_LLVM_TARGET_SPARC
* (WITH|WITHOUT)_LLVM_TARGET_X86
To not influence anything right now, all of these are on by default, in
situations where clang is enabled.
Selectively turning a few targets off manually should work. Turning on
only one target should work too, even if that target does not correspond
to the build architecture. (In that case, LLVM_NATIVE_ARCH will not be
defined, and you can only use the resulting clang executable for
cross-compiling.)
I performed a few measurements on one of the FreeBSD.org reference
machines, building clang from scratch, with all targets enabled, and
with only the x86 target enabled. The latter was ~12% faster in real
time (on a 32-core box), and ~14% faster in user time. For a full
buildworld the difference will probably be less pronounced, though.
