0ab27e6803 Bluetooth: shell: Add support for pairing confirm-only callbacks
Add a callback struct with only the pairing_confirm authentication
method. This is useful both for just-works testing as well as the
recently added fixed passkey support.

ef70fc85a9 Bluetooth: SMP: Fix SMP context init when sending security request
The code was not doing the right thing when we as peripheral would
send a security request to the central. First of all, the SEQ_REQ flag
was getting cleared by the pairing request handler, resulting in
pairing_confirm() callbacks for no reason. Secondly, the behavior in
encrypt_change() was not utilizing the smp_reset() helper as it should
have done.

Fix the situation by calling smp_init() when sending a security
request, and detect that this has been done when receiving a pairing
request. Also do the appropriate cleanup if the result is an encrypt
change instead of a pairing request (in case we were already paired
with the peer).

805e2f2c79 net: eth: mgmt: Merge 802.1Qav related mgmt requests
There are too many individual requests for Qav related parameters. There
are more Qav parameters that need to be supported (and will be supported
soon - both on the GET and SET side). Handling it the way it was handled
so far would render the eth mgmt API dominated by Qav parameters. That
would make the file hard to read and understand.

Instead of that - use a single GET and SET requests for all Qav
parameters. This works by adding a separate enum with Qav request type
to the ethernet_qav_param struct.

Additionally this approach makes it much easier to document it all since
we now have just a single request and documentation comments in the
ethernet_qav_param struct.

the current controller lacks any special ECC support, so enable
TINYCRYPT_ECC by default for such a configuration.

2. TLS credential (and other TLS parameters) should be set on a socket
using setsockopt().

573f32b6d2 userspace: compartmentalized app memory organization
Summary: revised attempt at addressing issue 6290.  The
following provides an alternative to using
CONFIG_APPLICATION_MEMORY by compartmentalizing data into
Memory Domains.  Dependent on MPU limitations, supports
compartmentalized Memory Domains for 1...N logical
applications.  This is considered an initial attempt at
designing flexible compartmentalized Memory Domains for
multiple logical applications and, with the provided python
script and edited CMakeLists.txt, provides support for power
of 2 aligned MPU architectures.

Overview: The current patch uses qualifiers to group data into
subsections.  The qualifier usage allows for dynamic subsection
creation and affords the developer a large amount of flexibility
in the grouping, naming, and size of the resulting partitions and
domains that are built on these subsections. By additional macro
calls, functions are created that help calculate the size,
address, and permissions for the subsections and enable the
developer to control application data in specified partitions and
memory domains.

Background: Initial attempts focused on creating a single
section in the linker script that then contained internally
grouped variables/data to allow MPU/MMU alignment and protection.
This did not provide additional functionality beyond
CONFIG_APPLICATION_MEMORY as we were unable to reliably group
data or determine their grouping via exported linker symbols.
Thus, the resulting decision was made to dynamically create
subsections using the current qualifier method. An attempt to
group the data by object file was tested, but found that this
broke applications such as ztest where two object files are
created: ztest and main.  This also creates an issue of grouping
the two object files together in the same memory domain while
also allowing for compartmenting other data among threads.

Because it is not possible to know a) the name of the partition
and thus the symbol in the linker, b) the size of all the data
in the subsection, nor c) the overall number of partitions
created by the developer, it was not feasible to align the
subsections at compile time without using dynamically generated
linker script for MPU architectures requiring power of 2
alignment.

In order to provide support for MPU architectures that require a
power of 2 alignment, a python script is run at build prior to
when linker_priv_stacks.cmd is generated.  This script scans the
built object files for all possible partitions and the names given
to them. It then generates a linker file (app_smem.ld) that is
included in the main linker.ld file.  This app_smem.ld allows the
compiler and linker to then create each subsection and align to
the next power of 2.

Usage:
 - Requires: app_memory/app_memdomain.h .
 - _app_dmem(id) marks a variable to be placed into a data
section for memory partition id.
 - _app_bmem(id) marks a variable to be placed into a bss
section for memory partition id.
 - These are seen in the linker.map as "data_smem_id" and
"data_smem_idb".
 - To create a k_mem_partition, call the macro
app_mem_partition(part0) where "part0" is the name then used to
refer to that partition. This macro only creates a function and
necessary data structures for the later "initialization".
 - To create a memory domain for the partition, the macro
app_mem_domain(dom0) is called where "dom0" is the name then
used for the memory domain.
 - To initialize the partition (effectively adding the partition
to a linked list), init_part_part0() is called. This is followed
by init_app_memory(), which walks all partitions in the linked
list and calculates the sizes for each partition.
 - Once the partition is initialized, the domain can be
initialized with init_domain_dom0(part0) which initializes the
domain with partition part0.
 - After the domain has been initialized, the current thread
can be added using add_thread_dom0(k_current_get()).
 - The code used in ztests ans kernel/init has been added under
a conditional #ifdef to isolate the code from other tests.
The userspace test CMakeLists.txt file has commands to insert
the CONFIG_APP_SHARED_MEM definition into the required build
targets.
  Example:
        /* create partition at top of file outside functions */
        app_mem_partition(part0);
        /* create domain */
        app_mem_domain(dom0);
        _app_dmem(dom0) int var1;
        _app_bmem(dom0) static volatile int var2;

        int main()
        {
                init_part_part0();
                init_app_memory();
                init_domain_dom0(part0);
                add_thread_dom0(k_current_get());
                ...
        }

 - If multiple partitions are being created, a variadic
preprocessor macro can be used as provided in
app_macro_support.h:

        FOR_EACH(app_mem_partition, part0, part1, part2);

or, for multiple domains, similarly:

        FOR_EACH(app_mem_domain, dom0, dom1);

Similarly, the init_part_* can also be used in the macro:

        FOR_EACH(init_part, part0, part1, part2);

Testing:
 - This has been successfully tested on qemu_x86 and the
ARM frdm_k64f board.  It compiles and builds power of 2
aligned subsections for the linker script on the 96b_carbon
boards.  These power of 2 alignments have been checked by
hand and are viewable in the zephyr.map file that is
produced during build. However, due to a shortage of
available MPU regions on the 96b_carbon board, we are unable
to test this.
 - When run on the 96b_carbon board, the test suite will
enter execution, but each individaul test will fail due to
an MPU FAULT.  This is expected as the required number of
MPU regions exceeds the number allowed due to the static
allocation. As the MPU driver does not detect this issue,
the fault occurs because the data being accessed has been
placed outside the active MPU region.
 - This now compiles successfully for the ARC boards
em_starterkit_em7d and em_starterkit_em7d_v22. However,
as we lack ARC hardware to run this build on, we are unable
to test this build.

Current known issues:
1) While the script and edited CMakeLists.txt creates the
ability to align to the next power of 2, this does not
address the shortage of available MPU regions on certain
devices (e.g. 96b_carbon).  In testing the APB and PPB
regions were commented out.
2) checkpatch.pl lists several issues regarding the
following:
a) Complex macros. The FOR_EACH macros as defined in
app_macro_support.h are listed as complex macros needing
parentheses.  Adding parentheses breaks their
functionality, and we have otherwise been unable to
resolve the reported error.
b) __aligned() preferred. The _app_dmem_pad() and
_app_bmem_pad() macros give warnings that __aligned()
is preferred. Prior iterations had this implementation,
which resulted in errors due to "complex macros".
c) Trailing semicolon. The macro init_part(name) has
a trailing semicolon as the semicolon is needed for the
inlined macro call that is generated when this macro
expands.

Update: updated to alternative CONFIG_APPLCATION_MEMORY.
Added config option CONFIG_APP_SHARED_MEM to enable a new section
app_smem to contain the shared memory component.  This commit
seperates the Kconfig definition from the definition used for the
conditional code.  The change is in response to changes in the
way the build system treats definitions.  The python script used
to generate a linker script for app_smem was also midified to
simplify the alignment directives.  A default linker script
app_smem.ld was added to remove the conditional includes dependency
on CONFIG_APP_SHARED_MEM.  By addining the default linker script
the prebuild stages link properly prior to the python script running

1292609458 logging: Use vsnprintk instead of vsnprintf
The printk family of functions is used elsewhere, so make this
consistent. Also, printk has a smaller stack footprint.

c68ab81f89 cmake: settings: Don't add ext nffs include dir to global includes
The settings subsystem has been adding nffs's include dir to the
global set of paths. Presumably because app's will need acces. But
this is no longer necessary as we default to linking 'app' with FS,
which again has the NFFS include paths.

4c60c510c3 cmake: default to linking 'app' with the interface library 'FS'
This patch removes the need for application build script code to
explicitly link 'app' with a filesystem implementation.

It does this by introducing a zephyr interface library called 'FS'
that contains the usage requirements for linking with the filesystem
library subsys__fs and using Kconfig to default to linking the 'app'
library with this interface library.
