The change from "slave" processes to "minion" processes to "worker"
processes left some less-than-coherent names:
1. "enslave" turned into the ungrammatical "enworker".
2. "slp" (SLave Pointer) turned into "mlp" (Minion [L] Pointer?).
Convert "enworker" to "create_workers" (the function in question forks
off 3 worker processes), and replace "mlp" with "wp" (Worker Pointer)
and "tmlp" with "twp" (Temporary Worker Pointer).

the only linuxkpi reference to color, and then drop color- and
parent-related definitions that are defined and used only in rbtree.h.
This is intended to be entirely cosmetic, with no impact on program

read and write rb parent pointers.

Ports bsd.kmod.mk explicitly sets MK_KERNEL_SYMBOLS=no to prevent auto-
splitting of debuginfo from kernel modules. If that knob is set, don't
split out a .ko.debug and .ko from .ko.full; just generate a .ko with
debuginfo and leave it be.
Otherwise, with DEBUG_FLAGS set and MK_KERNEL_SYMBOLS=no, we would helpfully
strip out the debuginfo from the .ko.full and then not install it. That is
not the desired result a WITH_DEBUG port kmod build.

Sort(1)'s radixsort implementation was broken for multibyte LC_CTYPEs in at
least two ways:
* In actual radix sort, it would only bucket the least significant
byte from each wchar, ignoring the 24 most-significant bits of each
unicode character.
* In degenerate cases / "fast paths," it would fall back to another
sorting algorithm (default: mergesort) with a bogus comparator
offset. The string comparison functions in sort(1) take an offset
in units of the operating character size. However, radixsort was
passing an offset in units of bytes. The byte offset must be
divided by sizeof(wchar_t).
This revision addresses both discovered issues.
Some example testcases:
$ (echo 耳 ; echo 脳 ; echo 耳) | \
LC_CTYPE=ja_JP.UTF-8 LC_COLLATE=C LANG=C sort --radixsort --debug
$ (echo 耳 ; echo 脳 ; echo 耳) | \
LC_CTYPE=C LC_COLLATE=C LANG=C sort --radixsort --debug
$ (for i in $(jot 34); do echo 耳耳耳耳耳; echo 耳耳耳耳脳; echo 耳耳耳耳脴; done) | \

OpenZFS generates events with a "zio_timestamp" field, which gets mistaken for
"timestamp" by libdevdctl due to imprecise string matching. Then later it is
assumed a "timestamp" field exists when it doesn't and an exception is thrown.
Add a space to the search string so we match exactly "timestamp" rather than
anything with that as a suffix.

We want newer versions of libzfs_core to run against an existing
zfs kernel module (i.e. a deferred reboot or module reload after
an update).
Programmatically document, via a zfs_ioc_key_t, the valid arguments
for the ioc commands that rely on nvpair input arguments (i.e. non
legacy commands from libzfs_core). Automatically verify the expected
pairs before dispatching a command.
This initial phase focuses on the non-legacy ioctls. A follow-on
change can address the legacy ioctl input from the zfs_cmd_t.
The zfs_ioc_key_t for zfs_keys_channel_program looks like:
static const zfs_ioc_key_t zfs_keys_channel_program[] = {
{"program", DATA_TYPE_STRING, 0},
{"arg", DATA_TYPE_UNKNOWN, 0},
{"sync", DATA_TYPE_BOOLEAN_VALUE, ZK_OPTIONAL},
{"instrlimit", DATA_TYPE_UINT64, ZK_OPTIONAL},
{"memlimit", DATA_TYPE_UINT64, ZK_OPTIONAL},
};
Introduce four input errors to identify specific input failures
(in addition to generic argument value errors like EINVAL, ERANGE,
EBADF, and E2BIG).
ZFS_ERR_IOC_CMD_UNAVAIL the ioctl number is not supported by kernel
ZFS_ERR_IOC_ARG_UNAVAIL an input argument is not supported by kernel
ZFS_ERR_IOC_ARG_REQUIRED a required input argument is missing
ZFS_ERR_IOC_ARG_BADTYPE an input argument has an invalid type

Networking is broken if the driver configures its (virtual) hardware to
use a hash algorithm (or a key) different from the one that the network
stack (software RSS) uses. This can be seen with connections initiated
from the host. The PCB will be placed into the hash table based on the
hash value calculated by the software. The hardware-calculated hash
value in reponse packets will be different, so the PCB won't be found.
Tested with a kernel compiled with 'options RSS' on an instance with ena

This permits requests to provide the AAD in a separate side buffer
instead of as a region in the crypto request input buffer. This is
useful when the main data buffer might not contain the full AAD
(e.g. for TLS or IPsec with ESN).
Unlike separate IVs which are constrained in size and stored in an
array in struct cryptop, separate AAD is provided by the caller
setting a new crp_aad pointer to the buffer. The caller must ensure
the pointer remains valid and the buffer contents static until the
request is completed (e.g. when the callback routine is invoked).
As with separate output buffers, not all drivers support this feature.
Consumers must request use of this feature via a new session flag.
To aid in driver testing, kern.crypto.cryptodev_separate_aad can be
set to force /dev/crypto requests to use a separate AAD buffer.

The assumption in zio_ddt_free() is that ddt_phys_select() must
always find a match. However, if that fails due to a damaged
DDT or some other reason the code will NULL dereference in
ddt_phys_decref().
While this should never happen it has been observed on various
platforms. The result is that unless your willing to patch the
ZFS code the pool is inaccessible. Therefore, we're choosing
to more gracefully handle this case rather than leave it fatal.
