1578e70eaf net: lwm2m: Add path generation macro
Currently, the Zephyr LwM2M code base is littered with hard-coded
object- and resource IDs, such as

    /* Mark 1st instance of security object as a bootstrap server */
    lwm2m_engine_set_u8("0/0/1", 1);

The purpose of this LoC is extremely opaque without the accompanying
comment. Each use of a resource path requires constantly checking
headers or the object registry to ensure you're not misremembering IDs.

To alleviate this, this commit introduces a variadic LwM2M path
expansion macro which performs preprocessor stringification on each
argument. For instance, "0/0/1" can now be written as

    LWM2M_PATH(LWM2M_OBJECT_SECURITY_ID, 0, SECURITY_BOOTSTRAP_FLAG_ID)

which, while albeit lengthier, avoids the use of hard-coded string
literals, thus making the code much more immediately understandable.

ffab099eb9 Bluetooth: add destroy callback to indication
Adds a `destroy` callback to the `struct bt_gatt_indicate_params` which
is used to signify to the application that the indication operation has
completed and the struct instance can be freed/destroyed.

This is required as the number of indication value callbacks that will
be triggered is not known by the caller when the `conn` parameter is
`NULL`.

Tracking when this callback should be run is mananged by a private
reference counter inside the struct.

170f17e0e7 Bluetooth: indication callback signature update
Update the signature of the `bt_gatt_indicate_func_t` callback type by
replacing the attr pointer with a pointer to the
`bt_gatt_indicate_params` struct that was used to start the indication.

This allows the callback to free the `bt_gatt_indicate_params` instance
if it was allocated from storage, while still allowing the
`bt_gatt_attr` value to be accessed through `params->attr`.

Allocating the `bt_gatt_indicate_params` instance from storage is
desirable as multiple indications can be queued, however each instance
must be valid until the callback is run.

Implements API update from #29357

542a7fa25d arch: riscv: add memory protection support
The IRQ handler has had a major changes to manage syscall, reschedule
and interrupt from user thread and stack guard.

Add userspace support:
- Use a global variable to know if the current execution is user or
  machine. The location of this variable is read only for all user
  thread and read/write for kernel thread.
- Memory shared is supported.
- Use dynamic allocation to optimize PMP slot usage. If the area size
  is a power of 2, only one PMP slot is used, else 2 are used.

Add stack guard support:
- Use MPRV bit to force PMP rules to machine mode execution.
- IRQ stack have a locked stack guard to avoid re-write PMP
  configuration registers for each interruption and then win some
  cycle.
- The IRQ stack is used as "temporary" stack at the beginning of IRQ
  handler to save current ESF. That avoid to trigger write fault on
  thread stack during store ESF which that call IRQ handler to
  infinity.
- A stack guard is also setup for privileged stack of a user thread.

Thread:
- A PMP setup is specific to each thread. PMP setup are saved in each
  thread structure to improve reschedule performance.

Moves mesh feature configuration to a separate module, deprecating the
bt_mesh_cfg_srv structure. The initial values for the features should
now be enabled through KConfig, where new config entries have been added

This removes the upward dependency on the config server from the core
stack, and makes the config server a pure frontend for the configuration
states, as all spec mandated behavior around the feature states is now

397b2a71fa net: lwm2m: Add a callback to notify socket errors to engine users
Currently, when socket errors occur during receive, the LwM2M engine
restarts the state machine and registers again to the server. While this
works in simple use case (only RD client socket open), it's not a valid
approach when more sockets are open (FW update socket).

Fix this by introducing socket fault callback, which is registered by
the LwM2M engine users. This way, a proper socket owner is notified on
error and can pertake appropriate action.

For RD socket errors the behaviour remains the same - the state machine
is reset and the client registers again to the server. For FW update
socket, handle the error by reopening the socket and retransmitting the
last request. This allows to resume the download from the point the
error occured, w/o a need to start from scratch.

d2a72273b7 x86: add support for common page tables
We provide an option for low-memory systems to use a single set
of page tables for all threads. This is only supported if
KPTI and SMP are disabled. This configuration saves a considerable
amount of RAM, especially if multiple memory domains are used,
at a cost of context switching overhead.

Some caching techniques are used to reduce the amount of context
switch updates; the page tables aren't updated if switching to
a supervisor thread, and the page table configuration of the last
user thread switched in is cached.
