Literal references to /usr/local exist in a large number of files in
the FreeBSD base system. Many are in contributed software, in configuration
files, or in the documentation, but 19 uses have been identified in C
source files or headers outside the contrib and sys/contrib directories.
This commit makes it possible to set _PATH_LOCALBASE in paths.h to use
a different prefix for locally installed software.
In order to avoid changes to openssh source files, LOCALBASE is passed to
the build via Makefiles under src/secure. While _PATH_LOCALBASE could have
been used here, there is precedent in the construction of the path used to
a xauth program which depends on the LOCALBASE value passed on the compiler
command line to select a non-default directory.
This could be changed in a later commit to make the openssh build
consistently use _PATH_LOCALBASE. It is considered out-of-scope for this
commit.

Upon a bit of debugging, it turns out that /dev/null inside the chroot
environment is full random bytes, which cause "make -f /dev/null" to
misbehave. Mounting a proper devfs inside the chroot seems to be the most
appropriate way to fix it.

must exist in the old kernel.

Version 0.2 of the SBI specification [1] marked the existing SBI
functions as "legacy" in order to move to a newer calling convention. It
also introduced a set of replacement extensions for some of the legacy
functionality. In particular, the TIME, IPI, and RFENCE extensions
implement and extend the semantics of their legacy counterparts, while
conforming to the newer version of the spec.
Update our SBI code to use the new replacement extensions when
available, and fall back to the legacy ones. These will eventually be
dropped, when support for version 0.2 is ubiquitous.

__FreeBSD__ is defined by the compiler derived from the triple. When
building FreeBSD 11 on a FreeBSD 12 with a CROSS_TOOLCHAIN=llvm10,
__FreeBSD__ was set to 12 when building lib32 (for some reason no triple
is being passed which seems to mean that we're taking default values
from the build system). This in turn meant we end up with a double

Without the 'car limit' enabled (before this), running sequential ZFS scrub
on HDD without command queuing support, I've measured latency on concurrent
random reads reaching 4 seconds (surprised that not more). Enabling this
reduced the latency to 65 milliseconds, while scrub still doing ~180MB/s.
For disks with command queuing this does not make much difference (if any),
since most time all the requests are queued down to the disk or HBA, leaving
nothing in the queue to sort. And even if something does not fit, staying on
the queue, it is likely not for long. To not limit sorting in such bursty
scenarios I've added batched counter zeroing when the queue is getting empty.
The internal scheduler of the SAS HDD I was testing seems to be even more
loyal to random I/O, reducing the scrub speed to ~120MB/s. So in case
somebody worried this is limit is too strict -- it actually looks relaxed.

SAM-3 specification introduced concept of Task Priority, that was renamed
to Command Priority in SAM-4, and supported by all modern SCSI transports.
It provides 15 levels of relative priorities: 1 - highest, 15 - lowest and
0 - default. SAT specification for SATA devices translates priorities 1-3
into NCQ high priority.
This change adds new "priority" field into empty spots of struct ccb_scsiio
and struct ccb_accept_tio of CAM and struct ctl_scsiio of CTL. Respective
support is added into iscsi(4), isp(4), mpr(4), mps(4) and ocs_fc(4) drivers
for both initiator and where applicable target roles. Minimal support was
added to CTL to receive the priority value from different frontends, pass it
between HA controllers and report in few places.
This patch does not add consumers of this functionality, so nothing should
really change yet, since the field is still set to 0 (default) on initiator
and not actively used on target. Those are to be implemented separately.
I've confirmed priority working on WD Red SATA disks connected via mpr(4)
and properly transferred to CTL target via iscsi(4), isp(4) and ocs_fc(4).
While there, added missing tag_action support to ocs_fc(4) initiator role.

over various major releases. Superblock check hashes were added for
the 12 release and cylinder-group and inode check hashes will appear
in the 13 release.
When a disk with a UFS filesystem is writably mounted, the kernel
clears the feature flags for anything that it does not support. For
example, if a UFS disk from a 12-stable kernel is mounted on an
11-stable system, the 11-stable kernel will clear the flag in the
filesystem superblock that indicates that superblock check-hashs
are being maintained. Thus if the disk is later moved back to a
12-stable system, the 12-stable system will know to ignore its
incorrect check-hash.
If the only filesystem modification done on the earlier kernel is
to run a utility such as growfs(8) that modifies the superblock but
neither updates the check-hash nor clears the feature flag indicating
that it does not support the check-hash, the disk will fail to mount
if it is moved back to its original newer kernel.
This patch moves the code that clears the filesystem feature flags
from the mount code (ffs_mountfs()) to the code that reads the
superblock (ffs_sbget()). As ffs_sbget() is used by the kernel mount
code and is imported into libufs(3), all the filesystem utilities
will now also clear these flags when they make modifications to the
filesystem.
As suggested by John Baldwin, fsck_ffs(8) has been changed to accept
and repair bad superblock check-hashes rather than refusing to run.
This change allows fsck to recover filesystems that have been impacted
by utilities older than those created after this change and is a
sensible thing to do in any event.

We no longer support building the kernel with the old intel
compiler. Remove support for it from in_cksum. Should there be
interest in reviving it, this is as likely to get in the way as to
help anyway.
The intel compiler support has badly decayed over the years. Stop
pretending that we support it. Note, I've stopped short of requiring
gcc builtin support with this commit since other compilers may be used
to build non-base software and we need to support those so more
investigation is needed before simplifying further.
We don't support building the kernel from such old compilers, nor with
the Intel Compiler specifically. Remove support for this old construct
that was copied from stdbool.h and not relevant here.
We no longer support old versions of GCC. Remove this check by
assuming it's false. That will make the entire expression false. Also
remove support for Intel compiler, it's badly bitrotted. Technically,
this removes support for C89 and K&R from compilers that don't define
_Bool in those compilation environments as well. I'm unaware of any
working compiler today for which that would be relevant (pcc has it
and tcc sadly isn't working for other reasons), though if one
pops up in ports, I'll work to resolve the issue.
rpcbind is now considered a security risk for some sites.
Since an NFSv4 only NFS server does not need rpcbind,

with rpcbind.
