4dc0353bcd net: openthread: store settings in RAM if there is no flash driver
This commit adds an option to store OpenThread settings in RAM for the
case where the flash driver is not available. This can be useful
for testing openthread on new platforms which are still under
development.

8ac11b9b6f net: openthread: Fix for OT prompt in the Zephyr shell
OpenThread has changed it's behaviour in terms of prompt printing in the
CLI module. Previously it was only printed on the UART CLI backend, now
it's printed on every CLI backend. This results in a double prompt being
printed when combined with Zephyr shell (one from OT and other form
Zephyr).

This commit adds a temporary fix to prevent OT prompt from being printed
in Zehpyr shell. As a long term solution we should add an option to
OpenThread to allow to disable prompt on the output.

enables that backend.

Also, another Kconfig option:
OPENTHREAD_PLATFORM_KEY_REFERENCES_ENABLE, implied by the
former, which enables usage of key references instead of
literal keys in OpenThread. It will eventually allow
OpenThread applications to keep sensitive data such as
encryption keys in the secure storage, accessible from the

If a firmware update is fetched from a server, and no port number is set

If a port different from the peer port is to be used for firmware
update, this has to be set explicitly in the URI:
coap://example.com:5683/fw_update.

This fix adds CONFIG_LWM2M_FIRMWARE_PORT, which will be used when

cf49699b0d net: sockets: socketpair: fix locking
The irq_lock() usage here is incompatible with SMP systems, and one's
first reaction might be to convert it to a spinlock.

But are those irq_lock() instances really necessary?

Commit 6161ea2542 ("net: socket: socketpair: mitigate possible race
condition") doesn't say much:

> There was a possible race condition between sock_is_nonblock()
> and k_sem_take() in spair_read() and spair_write() that was
> mitigated.

A possible race without the irq_lock would be:

thread A                thread B
|                       |
+ spair_write():        |
+   is_nonblock = sock_is_nonblock(spair); [false]
*   [preemption here]   |
|                       + spair_ioctl():
|                       +   res = k_sem_take(&spair->sem, K_FOREVER);
|                       +   [...]
|                       +   spair->flags |= SPAIR_FLAG_NONBLOCK;
|                       *   [preemption here]
+   res = k_sem_take(&spair->sem, K_NO_WAIT); [-1]
+   if (res < 0) {      |
+     if (is_nonblock) { [skipped] }
*     res = k_sem_take(&spair->sem, K_FOREVER); [blocks here]
|                       +   [...]

But the version with irq_lock() isn't much better:

thread A                thread B
|                       |
|                       + spair_ioctl():
|                       +   res = k_sem_take(&spair->sem, K_FOREVER);
|                       +   [...]
|                       *   [preemption here]
+ spair_write():        |
+   irq_lock();         |
+   is_nonblock = sock_is_nonblock(spair); [false]
+   res = k_sem_take(&spair->sem, K_NO_WAIT); [-1]
+   irq_unlock();       |
*   [preemption here]   |
|                       +   spair->flags |= SPAIR_FLAG_NONBLOCK;
|                       +   [...]
|                       +   k_sem_give(&spair->sem);
|                       + spair_read():
|                       +   res = k_sem_take(&spair->sem, K_NO_WAIT);
|                       *   [preemption here]
+   if (res < 0) {      |
+     if (is_nonblock) { [skipped] }
*     res = k_sem_take(&spair->sem, K_FOREVER); [blocks here]

In both cases the last k_sem_take(K_FOREVER) will block despite
SPAIR_FLAG_NONBLOCK being set at that moment. Other race scenarios
exist too, and on SMP they are even more likely.

The only guarantee provided by the irq_lock() is to make sure that
whenever the semaphore is acquired then the is_nonblock value is always
current. A better way to achieve that and be SMP compatible is to simply
move the initial sock_is_nonblock() *after* the k_sem_take() and remove
those irq_locks().

0dbdcc770d net: sockets: Add socket processing priority
When creating a socket, all of the registered socket implementation are
processed in a sequence, allowing to find appropriate socket
implementation for specified family/type/protocol. So far however,
the order of processing was not clearly defined, leaving ambiguity if
multiple implmentations supported the same set of parameters.

Fix this, by registering socket priority along with implementation. This
makes the processing order of particular socket implementations
explicit, giving more flexibility to the user, for example when it's
