Changing the mode bits on a file with an NFS4 ACL results in the
NFS4 ACL being replaced by one matching the new mode bits being set,
so when restoring a file with an NFS4 ACL, set the owner/group/mode first
and then set the NFS4 ACL, so that setting the mode does not throw away
the ACL that we just set.

One year ago, I deprecated 'kern' in favor of 'kernel' for the system
name for some power events. I'm about to remove it from the kernel, but
realized there's been no warning generated for users. Preserve POLA by
converting on the fly here and issuing a warning for 14.x, and an fatal
error after we branch 15. Make compiling it an error on 16 to remove
the gross hack after we branch.

scrub rules have defaulted to handling fragments for a long time, but
since we removed "fragment crop" and "fragment drop-ovl" in 64b3b4d611
this has become less obvious and more expensive ("reassemble" being the
more expensive option, even if it's the one the vast majority of users
should be using).
Extend the 'scrub' syntax to allow fragment reassembly to be disabled,
while retaining the other scrub behaviour (e.g. TTL changes, random-id,
..) using 'scrub fragment no reassemble'.

The kernel handles the managment of UFS/FFS snapshots. Since UFS/FFS
updates filesystem data (rather than always writing changes to new
locations like ZFS), the kernel must check every filesystem write
to see if the block being written is part of a snapshot. If it is
part of a snapshot, then the kernel must make a copy of the old
block value into a newly allocated block for the snapshot before
allowing the write to be done. Similarly, if a block is being freed,
the kernel must check to see if it is part of a snapshot and let
the snapshot claim the block rather than freeing it for future use.
When a snapshot is freed, its blocks need to be offered to older
snapshots and freed only if no older snapshots wish to claim them.
When snapshots were added to UFS/FFS they were integrated into soft
updates and just a small part of the management of snapshots needed
to be added to fsck_ffs(8) as soft updates minimized the set of
snapshot changes that might need correction. When journaling was
added to soft updates a much more complete knowledge of snapshots
needed to be added to fsck_ffs(8) for it to be able to properly
handle the filesystem changes that a journal rollback needs to do
(specifically the freeing and allocation of blocks). Since this
functionality was unavailable, the use of snapshots was disabled
when running with journaled soft updates.
This set of changes imports the kernel code for the management of
snapshots to fsck_ffs(8). With this code in place it will become
possible to enable snapshots when running with journalled soft
updates. The most immediate benefit will be the ability to use
snapshots to take consistent filesystem dumps on live filesystems.
Future work will be done to update fsck_ffs(8) to be able to use
snapshots to run in background on live filesystems running with
journaled soft updates.

The size of the journaled soft-updates journal should be big enough
to hold two minutes of filesystem metadata-update activity. The
maximum size of the soft updates journal was set in the 1990s. At
the time it was assummed that disk arrays would top out at 16 drives
and disk writes per drive would top out at 500 per second. Today's
I/O subsystems are considerably bigger and faster than those limits.
Thus this delta removes the hard upper limit and lets tunefs(8) and
newfs(8) set the upper bound based on the size of the filesystem and
its cylinder groups.

On systems where mac_veriexec is enforced, init should run its scripts in verified mode.
This relies on the verify shell option introduced by D30464. init will detect if the shell
is /bin/sh, and in which case, add the verify option to the argument vector.
The verify option propagates to all files sourced by the shell, ensuring a better
protection than if the script was tested against an open(O_VERIFY) before running it.
This security can be bypassed with the kenv which overloads the shell to use.
However we feel confident that on systems running with mac_veriexec, this kenv will be blocked somehow.
Also, the verify option has no effect on systems where mac_veriexec is not loaded nor enforced.
