The loop was not tracking the correct next node in the list correctly.
However, it happened that the fix is way more involved than just fixing
that small issue, due to the way that semaphore group timeouts work.
Instead of handling timeouts one-by-one, we have to handle all timeouts
in a semaphore group as one. To do that, we use the fact that the
timeout of the real thread is always found first in the kernel's
timeout_q, and if it has expired, we do not even look at the timeouts of
the dummy threads.

Timeouts, when expiring on the same tick, should be handled in the same
order they were queued.

Queuing in the timeout_q of timeouts expiring on the same tick queue
them in reverse order: as soon as the new timeout finds a timeout
expiring on the same tick or later, it get prepended to that timeout:
this allows exiting the traversal of the timeout as soon as possible,
which is done with interrupts locked, thus reducing interrupt latency.
However, this has the side-effect of handling the timeouts expiring on
the same tick in the reverse order that they are queued.
For example:
thread_c, prio 4:
uint32_t uptime = k_uptime_get_32();
while(uptime == k_uptime_get_32()); /* align on tick */
k_timer_start(&timer_a, 5, 0);
k_timer_start(&timer_b, 5, 0);
thread_a, prio 5:
k_timer_status_sync(&timer_a);
printk("thread_a got timer_a\n");
thread_b, prio 5:
k_timer_status_sync(&timer_b);
printk("thread_b got timer_b\n");
One could "reasonably" expect thread_a to run first, since both threads
have the same prio, and timer_a was started before timer_b, thus
inserted first in the timeout_q first (time-wise). However, thread_b
will run before thread_a, since timer_b's timeout is prepended to
timer_a's.
This patch keeps the reversing of the order when adding timeouts in the
timeout_q, thus preserving the same interrupt latency; however, when
dequeuing them and adding them to the expired queue, we now reverse that
order _again_, causing the timeouts to be handled in the expected order.

Like SYS_DLIST_FOR_EACH_NODE(), but __dn contains a node where to fetch
the next node from, NULL to start at the head.
Note that the function does not iterate from @a node, but from
node->next. This allows the following:
sys_dnode_t *funcA(sys_dlist_t *list, sys_dnode_t *node)
{
SYS_DLIST_ITERATE_FROM_NODE(list, node) {
if (node == <some condition>) {
return node;
}
}
return NULL;
}
sys_dlist_t list = &<some list>;
sys_dnode_t *node = NULL;
do {
node = funcA(list, node)
if (node == <some other condition>) {
goto found;
}
} while(node);
<handle error>
found:

This has not bitten us yet, but it was a ticking timebomb.
This is similar to the issue that was found with irq_lock/irq_unlock
implementations on several architectures. Having a volatile variable is
not the way to force the sched_lock variable to be
incremented/decremented around the accesses to data it protects.
Instead, a compiler barrier must prevent the compiler from reordering
the memory accesses around setting of sched_lock. Needed in the inline
implementations _sched_lock()/_sched_unlock_no_reschedule(), which
resolve to simple decrement/increment of the per-thread sched_lock
variable.

Currently, for the following MQTT msg fields:
- client_id
- will_topic
- user_name
- topic
their length is computed inside the routine that receives the MQTT msg.
Although this simplifies development, also imposes one restriction:
data must be null-terminated. Sometimes, data is received from other
sources and not generated by the application, so the null-terminated
constraint may be considered problematic for the user.
This patch removes the assumption that string fields are null-terminated.
Current data structures are already prepared to handle this case, so no
API change is required.

This implementation of _tsc_read returns a 64-bit value that
is derived from the 64-bit tick count multiplied by hwcycles per tick,
and then it adds the current value from the 32-bit timer.
This produces a 64-bit time. There is a bunch of math here, which
could be avoided if the CPU is built with Real-Time-Clock option.
EM Starter Kit SOCs don't have this. I don't think Arduino 101 does
either.

When a GPIO pin is configured, the shim driver will first read the
current values in the controller registers to keep the other pins from
changing their configuration. After that it sets the bits for the
corresponding pin accordingly.
When the flag to enable interrupts is passed to the function, the
corresponding bits are all set properly, but no changes are made if
interrupts are not requested. This makes it impossible to disable
interrupts for a given pin once they've been enabled.
Fix it by always resetting the interrupt enabled bit when they have not
been requested. Other values can be left untouched as they won't have
any effect.
