"4.1.2 Log field transformation
In order to compress two-octet values into one-octet fields, the
following logarithmic transformation is used: any two-octet value is
mapped onto a one-octet field value representing the largest integer
n, where 2^(n-1) is less than or equal to the two-octet value."
Log field transformation table:
Log Field Value 2-octet Value
0x01 0x0001
0x02 0x0002 through 0x0003
0x03 0x0004 through 0x0007
0x04 0x0008 through 0x000F
0x05 0x0010 through 0x001F
0x06 0x0020 through 0x003F
0x07 0x0040 through 0x007F
0x08 0x0080 through 0x00FF
0x09 0x0100 through 0x01FF
0x0A 0x0200 through 0x03FF
0x0B 0x0400 through 0x07FF
0x0C 0x0800 through 0x0FFF
0x0D 0x1000 through 0x1FFF
0x0E 0x2000 through 0x3FFF
0x0F 0x4000 through 0x7FFF
0x10 0x8000 through 0xFFFF
"4.2.17.2 Heartbeat Publication Count Log
The Heartbeat Publication Count Log value between 0x01 and 0x11 shall
represent that smallest integer n where 2^(n-1) is greater than or
equal to the Heartbeat Publication Count value. For example, if the
Heartbeat Publication Count value is 0x0579, then the Heartbeat
Publication Count Log value would be 0x0C."
According to this definition 2^(n-1) is an upper bound for n log
value.
Proposed Publication Count Log transformation table:
Pub Count Log Value 2-octet Value
0x01 0x0001
0x02 0x0002
0x03 0x0003 through 0x0004
0x04 0x0005 through 0x0008
0x05 0x0009 through 0x0010
0x06 0x0011 through 0x0020
0x07 0x0021 through 0x0040
0x08 0x0041 through 0x0080
0x09 0x0081 through 0x0100
0x0A 0x0101 through 0x0200
0x0B 0x0201 through 0x0400
0x0C 0x0401 through 0x0800
0x0D 0x0801 through 0x1000
0x0E 0x1001 through 0x2000
0x0F 0x2001 through 0x4000
0x10 0x4001 through 0x8000
0x11 0x8001 through 0x10000
According to Log field transformation table 0x0579 would be
transformed to 0x0B and should be to transformed to 0x0C.

This patch fixes issue when receiving iv index greater than current
index + 42 in update mode. According to Specification when node is in
update state it should only accept iv index equal to the current iv
index. When node is in normal mode it should ignore index that is
greater than current index + 42.
This allows to pass MESH/NODE/IVU/BI-02-C.
Also this patch cleans up the iv update procedure, to make it easier
to read.

Kernel object metadata had an extra data field added recently to
store bounds for stack objects. Use this data field to assign
IDs to thread objects at build time. This has numerous advantages:
* Threads can be granted permissions on kernel objects before the
thread is initialized. Previously, it was necessary to call
k_thread_create() with a K_FOREVER delay, assign permissions, then
start the thread. Permissions are still completely cleared when
a thread exits.
* No need for runtime logic to manage thread IDs
* Build error if CONFIG_MAX_THREAD_BYTES is set too low

A CPU fault occurs when sys_k_event_logger_get_wait()
api invoked with config KERNEL_EVENT_LOGGER_THREAD
enabled.
sys_k_event_logger_get_wait() supposed to pend on a
semaphore when all the events from kernel event logger
are read.But when sys_k_event_logger_get_wait() inovked
with config KERNEL_EVENT_LOGGER_THREAD(i.e captures thread
events) subsquent call inside this function will write to
kernel event log buffer to capture pend event.This will
release the semaphore on which sys_k_event_logger_get_wait()
was pending hence thread gets unpend before swap gets called.
Which in other words a thread which is invoking
sys_k_event_logger_get_wait()(i. e sem_count = 0) get pends
and unpends in single function flow when KERNEL_EVENT_LOGGER_THREAD
enabled.
This would cause overlapping of the stack address where
return address of "_pend_current_thread" stored with esp of
callee saved(i. e thread->callee_saved.esp). Thus return adrress
of "_pend_current_thread" would be overwitten with zero. Which
in turn causes CPU fault.
The thread invoking sys_k_event_logger_get_wait() supposed
to only read the events of the threads which logged to kernel event
logger buffer. But it should not write to kernel event logger
buffer. Otherwise it would cause the race condition explained above.

This adds CONFIG_EXECUTE_XOR_WRITE, which is enabled by default on
systems that support controlling whether a page can contain executable
code. This is also known as W^X[1].
Trying to add a memory domain with a page that is both executable and
writable, either for supervisor mode threads, or for user mode threads,
will result in a kernel panic.
There are few cases where a writable page should also be executable
(JIT compilers, which are most likely out of scope for Zephyr), so an
option is provided to disable the check.
Since the memory domain APIs are executed in supervisor mode, a
determined person could bypass these checks with ease. This is seen
more as a way to avoid people shooting themselves in the foot.
