All system calls made from userspace which involve pointers to kernel
objects (including device drivers) will need to have those pointers
validated; userspace should never be able to crash the kernel by passing
it garbage.
The actual validation with _k_object_validate() will be in the system
call receiver code, which doesn't exist yet.
- CONFIG_USERSPACE introduced. We are somewhat far away from having an
end-to-end implementation, but at least need a Kconfig symbol to
guard the incoming code with. Formal documentation doesn't exist yet
either, but will appear later down the road once the implementation is
mostly finalized.
- In the memory region for RAM, the data section has been moved last,
past bss and noinit. This ensures that inserting generated tables
with addresses of kernel objects does not change the addresses of
those objects (which would make the table invalid)
- The DWARF debug information in the generated ELF binary is parsed to
fetch the locations of all kernel objects and pass this to gperf to
create a perfect hash table of their memory addresses.
- The generated gperf code doesn't know that we are exclusively working
with memory addresses and uses memory inefficently. A post-processing
script process_gperf.py adjusts the generated code before it is
compiled to work with pointer values directly and not strings
containing them.
- _k_object_init() calls inserted into the init functions for the set of
kernel object types we are going to support so far

The API name space for Bluetooth is bt_* and BT_* so it makes sense to
align the Kconfig name space with this. The additional benefit is that
this also makes the names shorter. It is also in line with what Linux
uses for Bluetooth Kconfig entries.
Some Bluetooth-related Networking Kconfig defines are renamed as well
in order to be consistent, such as NET_L2_BLUETOOTH.

This introduces an schema-based YAML validation process when loading
any YAML file, before doing any operations on them. An exception will
be raised at SanityConfigParser() if the file fails to verify with the
given schema.
Schemas are defined for the platform files in board///*.yaml and for
the (sample|testcase).yaml files. The verification is done using the
pykwalify python library. If not installed, a warning is printed and
the verification schema is skipped. At some point, we might want to
force it being installed.
The verification library is made a separate module (scl.py) so it can
be easily imported by others.

The CPU first checks the page directory entry for write
or user permissions on a particular page before looking
at the page table entry.
If a region configured all pages to be non user accessible,
and this was changed for a page within it to be accessible,
the PDE would not be updated and any access would still
return a page fault.
The least amount of runtime logic to deal with this is to
indicate at build time that some pages within a region may
be marked writable or user accessible at runtime, and to
pre-set the flags in the page directory entry accordingly.
The driving need for this is the region configuration for
kernel memory, which will have user permissions set at
runtime for stacks and user-configured memory domains.

In some cases, it's possible to share a DTC overlay across multiple
boards (one example is when the overlay just has to choose a

To support this, only go looking around in DTC_OVERLAY_DIR if
DTC_OVERLAY_FILE is not already given.

We have the same pattern for how we map a chosen property to the device
label that generates a Kconfig define. Rather than duplicating the code
over and over again, lets just iterate over a list of defines and chosen
properties. This also provides us a list we can use in the future to
special case handle the defines associated with names.

We will need this for stack memory protection scenarios
where a writable GDT with Task State Segment descriptors

This has one use-case: configuring the double-fault #DF
exception handler to do an IA task switch to a special
IA task with a known good stack, such that we can dump
diagnostic information and then panic.
Will be used for stack overflow detection in kernel mode,
as otherwise the CPU will triple-fault and reset.
