Add an "nextnoskip" sysctl that allows for listing of sysctls intended to be
normally skipped for cost reasons.
This makes it so the names/descriptions of those sysctls can be discovered with
sysctl -aN/sysctl -ad/sysctl -at.
It also makes it so children are visited when a node flagged with CTLFLAG_SKIP
is explicitly requested.
The intended use case is to mark the root "kstat" node with CTLFLAG_SKIP so that
the extensive and expensive stats are skipped by default but may still be easily
obtained without having to know them all (which may not even be possible) and
request each one-by-one.

Repeating the default WARNS here makes it slightly more difficult to

that.
Drop most of them; there is one in the blake2 kernel module, but I suspect
it should be dropped -- the default WARNS in the rest of the build doesn't
currently apply to kernel modules, and I haven't put too much thought into
whether it makes sense to make it so.

Fix unquoted test for an empty value, which broke nextboot(8) on non-ZFS /boot

The purpose of checksize() is to verify that the referenced cluster
chain size matches the recorded file size (up to 2^32 - 1) in the
directory entry. We follow the cluster chain, then multiple the
cluster count by bytes per cluster to get the physical size, then
check it against the recorded size.
When a file is close to 4 GiB (between 4GiB - cluster size and 4GiB,
both non-inclusive), the product of cluster count and bytes per
cluster would be exactly 4 GiB. On 32-bit systems, because size_t
is 32-bit, this would wrap back to 0, which will cause the file be
truncated to 0.
Fix this by using 64-bit physicalSize instead.

bootonce feature is temporary, one time boot, activated by
"bectl activate -t BE", "bectl activate -T BE" will reset the bootonce flag.
By default, the bootonce setting is reset on attempt to boot and the next
boot will use previously active BE.
By setting zfs_bootonce_activate="YES" in rc.conf, the bootonce BE will
be set permanently active.
bootonce dataset name is recorded in boot pool labels, bootenv area.
in case of nextboot, the nextboot_enable boolean variable is recorded in
freebsd:nvstore nvlist, also stored in boot pool label bootenv area.
On boot, the loader will process /boot/nextboot.conf if nextboot_enable
is "YES", and will set nextboot_enable to "NO", preventing /boot/nextboot.conf
processing on next boot.
bootonce and nextboot features are usable in both UEFI and BIOS boot.
To use bootonce/nextboot features, the boot loader needs to be updated on disk;
if loader.efi is stored on ESP, then ESP needs to be updated and
for BIOS boot, stage2 (zfsboot or gptzfsboot) needs to be updated
(gpart or other tools).
At this time, only lua loader is updated.

libifconfig_sfp.h provides an API in libifconfig for querying SFP module
properties, operational status, and vendor strings, as well as descriptions
of the various fields, string conversions, and other useful helpers for
implementing user interfaces.
SFP module status is obtained by reading registers via an I2C interface.
Descriptions of these registers and the values therein have been collected
in a Lua table which is used to generate all the boilerplace C headers and
source files for accessing these values, their names, and descriptions.
The generated code is fully commented and readable.
This is the first use of libifconfig in ifconfig itself. For now, the
scope remains very limited. Over time, more of ifconfig will be replaced
with libifconfig.
Some minor changes to the formatting of ifconfig output have been made:
- Module memory hex dumps are indented one extra space as a result of using
hexdump(3) instead of a bespoke hex dump function.
- Media descriptions have an added two-character short-name in parenthesis.
- QSFP modules were incorrectly displaying TX bias current as power. Now
TX channels display bias current, and this change has been made for both
SFP and QSFP modules for consistency.
A Lua binding for libifconfig including this functionality is implemented
but has not been included in this commit. The plan is for it to be
committed after dynamic module loading has been enabled in flua.

r356313 broke handling of dirty file system because we have restricted
the correction of "odd" byte sequences to checkfat(), and as a result
the dirty bit is never cleared. The old fsck_msdosfs code would write
FAT twice to fix the dirty bit, which is also not ideal.
Fix this by introducing a new rountine, cleardirty() which will perform
the set of clean bit only, and use it in checkfilesys() if we thought
the file system was dirty.

sysroot and avoid includes of kernel headers that may not exist on every

on FreeBSD 11+ as well as Linux and macOS.
We also have to avoid using the IO_SYNC macro since that may not be
available. In makefs it is only used to switch between calling
bwrite() and bdwrite() which both call the same function. Therefore we
can simply always call bwrite().
For our CheriBSD builds we always bootstrap makefs by setting

This is a re-apply r356249 with changes to make GCC happy.
This utility was initially written for FAT12/16, which were inherently
small. When FAT32 support was added, the old data structure and
algorithms remain used with minimal changes.
With growing size of FAT32 media, the current data structure that
requires 4 32-bit variables per each FAT32 table entry would consume up
to 4 GiB of RAM, which can be too big for systems with limited RAM
available.
Address this by taking a different approach of validating the FAT.
The FAT is essentially a set of linked lists of chains that was
referenced by directory entries, and the checker needs to make sure that
the linked chains of clusters do not have cross-linked chains, and every
chain were referenced by one and only one directory entry. Instead of
keeping track of the chain's 'head' cluster number, the size of the
chain, the used status of the chain and the "next" pointer which is
content of the FAT table, we create accessors for the FAT table data
for the "next" pointer, and keep only one bit to indicate if the
current cluster is a 'head' node of a cluster chain, in a bitmap.
We further overhaul the FAT checker to find out the possible head nodes
by excluding ones that are not (in other words, nodes that have some
other nodes claiming them as the next node) instead of marking the head
nodes for each node on the chain. This approach greatly reduced the
complexiety of computation from O(N^2) worst case, to an O(N) scan for
worst case. The file (cluster chain) length is not useful for the FAT
checker, so don't bother to calculate them in the FAT checker and
instead leave the task to the directory structure check, at which point
we would have non-crossed cluster chains, and we are guaranteed that
each cluster will be visited for at most one time.
When checking the directory structures, we use the head node indicator
to as the visited (used) flag: every cluster chain can only be
referenced by one directory entry, so we clear them when calculating
the length of the chain, and we can immediately tell if there are
anomalies in the directory entry.
As a result, the required RAM size is now 1 bit per each entry of
the FAT table, plus memory needed to hold the FAT table in memory,
instead of 16 bytes (=128 bits) per each entry. For FAT12 and FAT16,
we will load the whole FAT table into memory as they are smaller than
128KiB, and for FAT32, we first attempt to mmap() it into memory, and
when that fails, we would fall back to a simple LRU cache of 4 MiB of
RAM.
sbin/fsck_msdosfs/boot.c:
- Added additional sanity checks for valid FAT32/FAT16/FAT12 cluster
number.

is already damaged beyond repair.

the directory's second cluster is a valid one, which is examined
more throughly in a later checkchain() and does not prevent us
from proceeding further).

to avoid churn in Makefile.depend
DIRDEPS for cases such as OPENSSL, TCP_WRAPPERS etc

Previously the mkfs_msdos function (from newfs_msdos) emitted warnings
in the case that an image size is specified and the target is not a
file, or no size is specified and the target is not a character device.
The latter warning (not a character device) doesn't make sense when this
code is used in makefs, regardless of whether an image size is specified
or not.

mdmfs(8) lacks the ability to populate throwaway memory filesystems from an
existing directory.
This features permits an interesting setup where /var for instance lives on
a device where wear-leveling is something you want to avoid as much as
possible and nonetheless you don't want to lose your logs, ports metadata,
etc. Here are the steps:
1. Copy /var to /var.bak;
2. Mount an mfs into /var using -k /var.bak at startup;
3. Synchronize /var to /var.bak weekly and on shutdown.
Note that this more or less mimics OpenBSD's mount_mfs(8) -P flag.

The change is for the example in textdump.4 and the default ddb.conf.
First of all, doadump now requires an argument and it won't do a
textdump if the argument is not 'true'.
And 'textdump dump' is more idiomatic anyway.
For what it's worth, ddb 'dump' command seems to always request a vmcore
dump even if a textdump was requested earlier, e.g., by 'textdump set'.
Finally, ddb 'call' command is not documented.

-o will force the origin to be destroyed unconditionally.
BE_DESTROY_AUTOORIGIN, on the other hand, will only destroy the origin if it
matches the format used by be_snapshot. This lets us clean up the snapshots
that are clearly not user-managed (because we're creating them) while
leaving user-created snapshots in place and warning that they're still
around when the BE created goes away.
By default next_cmd() initializes only first u32 of opcode. O_ICMP6TYPE
opcode has array of bit masks to store corresponding ICMPv6 types.
An opcode that precedes O_ICMP6TYPE, e.g. O_IP6_DST, can have variable
length and during opcode filling it can modify memory that will be used
by O_ICMP6TYPE opcode. Without explicit initialization this leads to
creation of wrong opcode.

This change allows to specify a watchdog(9) timeout for a system
shutdown. The timeout is activated when the watchdogd daemon is
stopped. The idea is to a prevent any indefinite hang during late
stages of the shutdown. The feature is implemented in rc.d/watchdogd,
it builds upon watchdogd -x option.
Note that the shutdown timeout is not actiavted when the watchdogd
service is individually stopped by an operator. It is also not
activated for the 'shutdown' to the single-user mode. In those cases it
is assumed that the operator knows what they are doing and they have
means to recover the system should it hang.
Significant subchanges and implementation details:
- the argument to rc.shutdown, completely unused before, is assigned to
rc_shutdown variable that can be inspected by rc scripts
- init(8) passes "single" or "reboot" as the argument, this is not
changed
- the argument is not mandatory and if it is not set then rc_shutdown is
set to "unspecified"
- however, the default jail management scripts and jail configuration
examples have been updated to pass "jail" to rc.shutdown, just in case
- the new timeout can be set via watchdogd_shutdown_timeout rc option
- for consistency, the regular timeout can now be set via
watchdogd_timeout rc option
- watchdogd_shutdown_timeout and watchdogd_timeout override timeout
specifications in watchdogd_flags
- existing configurations, where the new rc options are not set, should
keep working as before
I am not particularly wed to any of the implementation specifics.
I am open to changing or removing any of them as long as the provided
functionality is the same (or very close) to the proposed one.
For example, I think it can be implemented without using watchdogd -x,
by means of watchdog(1) alone. In that case there would be a small
window between stopping watchdogd and running watchdog, but I think that
that is acceptable.

The two options are
* nocover/cover: Prevent/allow mounting over an existing root mountpoint.
E.g., "mount -t ufs -o nocover /dev/sd1a /usr/local" will fail if /usr/local
is already a mountpoint.
* emptydir/noemptydir: Prevent/allow mounting on a non-empty directory.
E.g., "mount -t ufs -o emptydir /dev/sd1a /usr" will fail.
Neither of these options is intended to be a default, for historical and
compatibility reasons.

ping(8) uses SO_TIMESTAMP, which attaches a timestamp to each IP datagram at
the time it's received by the kernel. Except that occasionally it doesn't.
Add a check to see whether such a timestamp was actually set before trying
to read it. This fixes segfaults that can happen when the kernel doesn't
attach a timestamp.
The bug has always existed, but prior to r351461 it manifested as an
implausible round-trip-time, not a segfault.

This command simply returns 0 at the moment and explicitly takes no
arguments. This should be used by utilities wanting to see if bectl can
operate on the system they're running, or with a specific root (`bectl -r`).
It may grow more checks than "will libbe successfully init" in the future,
but for now this is enough as that checks for the dataset mounted at "/" and
that it looks capable of being a BE root (e.g. it's not a top-level dataset)
bectl commands can now specify if they want to be silent, and this will turn
off libbe_print_on_error so they can control the output as needed. This is
already used in `bectl check`, and may be turned on in the future for some
other commands where libbe errors are better suppressed as the failure mode
may be obvious.

This turns into a warning in GCC 4.2 that 'reverse' may be used
uninitialized in this function. While I don't immediately see where it's
deciding this from (there's only two paths that make column != NULL, and
they both set reverse), initializing reverse earlier is good for clarity.

- Remove incomplete and dangerous ata_res decoding from ata_do_cmd().
Instead switch all functions that need the result to use get_ata_status(),
doing the same, but more careful, also reducing code duplication.
- Made get_ata_status() to also decode fixed format sense. In many cases
it is still not enough to make it useful, since it can only report results
of 28-bit command, but it is slightly better then nothing.
- Organize error reporting in ata_do_cmd(), so that if caller specified
AP_FLAG_CHK_COND, it is responsible for command errors (non-ioctl ones).
- Make HPA/AMA errors not fatal for `identify` subcommand.
- Fix reprobe() not being called on HPA/AMA when in quiet mode.
- Remove not very useful messages from `format` and `sanitize` commands
with -y flag. Once they started, they often can't be stopped any way.
