PR#254282 reports a problem where nullfs mounts cannot be
exported via mountd for FreeBSD 13.0.
The problem seems to be that, to do the nullfs mounts in
/etc/fstab, they require the "late" mount option, so that the
underlying filesystem is mounted (ZFS for the PR).
Adding "mountlate" to the REQUIRE list in /etc/rc.d/mountd
fixes the problem, but that results in a dependency cycle
because /etc/rc.d/lockd specifies:
REQUIRE: nfsd
BEFORE: DAEMON
--> which forces mountd to preceed DAEMON.
This patch removes "nfsd" from REQUIRE for lockd and statd,
then adds mountlate to REQUIRE for mountd, to fix this
problem. Having lockd REQUIRE nfsd was done in the NetBSD
code when it was pulled into FreeBSD and there does not
seem to be a need for this.
In case this causes problems, a long MFC has been specified.

If the device becomes unresponsive, the driver will not be able to
finish the reset process correctly. Timeout during version validation
indicates that the device is currently not responding. In that case
do not perform the reset and instead reschedule timer service. Because
of that the driver will continue trying to reset the device until it
succeeds or is detached.

The timer service was started when the interface was brought up and it
was stopped when it was brought down. Since ena_up requires the device
to be responsive, triggering the reset would become impossible if the
device became unresponsive with the interface down.
Since most of the functions in timer service already perform the check
to see if the device is running, this only requires starting the callout
in attach and stopping it when bringing the interface up or down to
avoid race between different admin queue calls.
Since callout functions for timer service are always called with the
same arguments, replace callout_{init,reset,drain} calls with
ENA_TIMER_{INIT,RESET,DRAIN} macros.

Since `ena_com_tx_comp_req_id_get` already checks for `req_id` validity,
the logic was exiting early, never giving `validate_tx_req_id` a chance
to trigger device reset.
Rewrite the logic so that device reset is called based on return value
of `ena_com_tx_comp_req_id_get` instead.

ena_tx_csum function did not check if IPv6 checksum offload was
requested it only checked checksum offloading flags for IPv4 packets.
Because of that, when encountering CSUM_IP6_* flags, the function simply
returned without actually setting checksum offloading in ena_ctx.
Check CUSM_IP6_* flags to enable IPv6 checksum offload.
Additionally, only IPv4 header was being parsed regardless of EtherType
field, because of that, value of L4 protocol read when actually trying
to send IPv6 packets was wrong. Use ip6_lasthdr function to get length
of all IPv6 headers and payload protocol.
Set the DF flag to 1 in order to allow the device to offload the IPv6
checksum calculation and achieve optimal performance.
Add CSUM6_OFFLOAD and CSUM_OFFLOAD definitions into ena_datapath.h.

Merge commit '2530eb1fa01bf28fbcfcdda58bd41e055dcb2e4a'
Adjust the driver to the upgraded ena-com part twofold:
First update is related to the driver's NUMA awareness.
Allocate I/O queue memory in NUMA domain local to the CPU bound to the
given queue, improving data access time. Since this can result in
performance hit for unaware users, this is done only when RSS
option is enabled, for other cases the driver relies on kernel to
allocate memory by itself.
Information about first CPU bound is saved in adapter structure, so
the binding persists after bringing the interface down and up again.
If there are more buckets than interface queues, the driver will try to
bind different interfaces to different CPUs using round-robin algorithm
(but it will not bind queues to CPUs which do not have any RSS buckets
associated with them). This is done to better utilize hardware
resources by spreading the load.
Add (read-only) per-queue sysctls in order to provide the following
information:
- queueN.domain: NUMA domain associated with the queue
- queueN.cpu: CPU affinity of the queue
The second change is for the CSUM_OFFLOAD constant, as ENA platform
file has removed its definition. To align to that change, it has been
added to the ena_datapath.h file.

Disable the gdb packet run length encoding for 3-symbol repetitions.
While it is technically possible to encode them, they have no advantage
over sending the characters verbatim (the resulting length is the same)
and they result in sending non-printable \x1f character. The protocol
has been designed with the intent of avoiding non-printable characters
and therefore the run length encoding is biased to emit \x20 (a space)
with the minimal intended run length of 4.
While at it, simplify the logic by merging the different 'if' blocks
into a single while loop, and moving 'runlen == 0' check lower.

Closes#12995
FreeBSD's implementation of zfs_uio_fault_move() returns EFAULT when a
page fault occurs while copying data in or out of user buffers. The VFS
treats such errors specially and will retry the I/O operation (which may
have made some partial progress).
When the FreeBSD and Linux implementations of zfs_write() were merged,
the handling of errors from dmu_write_uio_dbuf() changed such that
EFAULT is not handled as a partial write. For example, when appending
to a file, the z_size field of the znode is not updated after a partial
write resulting in EFAULT.
Restore the old handling of errors from dmu_write_uio_dbuf() to fix
this. This should have no impact on Linux, which has special handling
for EFAULT already.

Closes#12964
Raw receiving a snapshot back to the originating dataset is currently
impossible because of user accounting being present in the originating
dataset.
One solution would be resetting user accounting when raw receiving on
the receiving dataset. However, to recalculate it we would have to dirty
all dnodes, which may not be preferable on big datasets.
Instead, we rely on the os_phys flag
OBJSET_FLAG_USERACCOUNTING_COMPLETE to indicate that user accounting is
incomplete when raw receiving. Thus, on the next mount of the receiving
dataset the local mac protecting user accounting is zeroed out.
The flag is then cleared when user accounting of the raw received
snapshot is calculated.

When the eviction thread goes to shrink an ARC state, it allocates a set
of marker buffers used to hold its place in the state's sublists.
This can be problematic in low memory conditions, since
1) the allocation can be substantial, as we allocate NCPU markers;
2) on at least FreeBSD, page reclamation can block in
arc_wait_for_eviction()
In particular, in stress tests it's possible to hit a deadlock on
FreeBSD when the number of free pages is very low, wherein the system is
waiting for the page daemon to reclaim memory, the page daemon is
waiting for the ARC eviction thread to finish, and the ARC eviction
thread is blocked waiting for more memory.
Try to reduce the likelihood of such deadlocks by pre-allocating markers
for the eviction thread at ARC initialization time. When evicting
buffers from an ARC state, check to see if the current thread is the ARC
eviction thread, and use the pre-allocated markers for that purpose
rather than dynamically allocating them.

As of f833ab9dd1 procctl(2) allows idtype P_PID with id = 0 as a
shortcut for the calling process ID. The shortcut also bypasses the
p_cansee / p_candebug test (since the process is able to act on itself.)
At present if the security.bsd.unprivileged_proc_debug sysctl is 0 then
procctl(P_PID, getpid(), ... for a process to act on itself will fail,
but procctl(P_PID, 0, ... will succeed. This should likely be addressed
with a kernel change.
In any case the id = 0 shortcut is a tiny optimization for a process to
act on itself and allows the self-procctl to succeed, so use it in ssh.
