The final 'mv' to install a fetched leap-list file can fail (due to a
readonly fs, or schg flags, for example), and that leads to mv(1)
prompting the user, stopping the boot process. Instead, use mv -f
to supress the prompting, and if verbose mode is on, emit a warning
that the existing file cannot be replaced.

Most NFSv4.1 compound RPCs start with a Sequence operation. For these
cases, save the slotid and note that it is saved by setting ND_HASSLOTID.
This is used by r335568 to free up the session slot and disable it.

r335568 uses a flag called ND_HASSLOTID to indicate that the slotid is set,
so it can free and invalidate it.
This flag needs to be set, which will be done in a subsequent commit.

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.

This patch adds a counter that limits the number of disabled mirrored DSs
to mirror level - 1. It also makes a small change that keeps a Write that

the DS.
This patch only affects the pNFS server.

Fix is to print the correct number of entries based on the value of

The Linux compatibility code was converting the version number (e.g.
2.6.32) in two different ways and then comparing the results.
The linux_map_osrel() function converted MAJOR.MINOR.PATCH similar to
what FreeBSD does natively. I.e. where major=v0, minor=v1, and patch=v2
v = v0 * 1000000 + v1 * 1000 + v2;
The LINUX_KERNVER() macro, on the other hand, converted the value with
bit shifts. I.e. where major=a, minor=b, and patch=c
v = (((a) << 16) + ((b) << 8) + (c))
The Linux kernel uses the later format via the KERNEL_VERSION() macro in
include/generated/uapi/linux/version.h
Fix is to use the LINUX_KERNVER() macro in linux_map_osrel() as well as
in the .trans_osrel functions.

The refactoring in r335479 overlooked the fact that the dynamic kenv can
also be switched to if hintmode == 0. This is problematic because the
checkmethod bits are only ever ran once, but it worked previously because
the use_kenv was a global state and the first lookup would enable it if
occurring after the dynamic environment has been setup.
Extending our local definition of use_kenv to include all non-STATIC
hintmodes as long as the dynamic_kenv is setup fixes this. We still have
potential issues if the dynamic kenv comes up while we're doing an anchored
search through the environment, but this is not much of a concern right now
because:
1.) The dynamic environment comes up super early in boot, just after kmem
2.) This is going to get rewritten to provide a safer mechanism for the
anchored searches, ensuring that we continue using the same environment
chain (dynamic env or static fallback) for all anchored search invocations

than assigning spigen device names in order of creation, this uses a device
name that corresponds to the owning spibus and chip-select index.
Example: /dev/spigen0.1 would be a child of spibus0, and use cs = 1
The intent is for systems like Raspberry Pi to have a consistent way of
using an SPI interface with a specific cs value from a user application.
Otherwise, there is no consistent way of knowing which cs pin will be
assigned to a particular spigen device. The alternative is to specify
everything in "the right order" in an overlay file, which is less than
ideal. Additionally, this duplicates (to some extent) the way Linux handles
a similar situation with their 'spidev' device, so it would be somewhat
familiar to those who also use Linux.
A new kernel config option, SPIGEN_LEGACY_CDEVNAME, causes the driver to
also create /dev/spigenN device name aliases, with N incrementing in the
order of device instantiation. This is provided to ease the transition
for existing systems using the original naming convention (particularly
when these changes are MFC'd to stable branches).
