In slow networks, like Nb-IOT, when using queue mode,
there might be significant delay between the time we
put the packet into a transmission queue and the time
we actually start transmitting.
This might cause QUEUE_RX_OFF state to be triggered earlier
than expected. Remedy the issue by updating the timestamp on the

There are several subsystems and boards which require a relatively large
system heap (used by k_malloc()) to function properly. This became even
more notable with the recent introduction of the ACPICA library, which
causes ACPI-using boards to require a system heap of up to several
megabytes in size.
Until now, subsystems and boards have tried to solve this by having
Kconfig overlays which modify the default value of HEAP_MEM_POOL_SIZE.
This works ok, except when applications start explicitly setting values
in their prj.conf files:
$ git grep CONFIG_HEAP_MEM_POOL_SIZE= tests samples|wc -l
157
The vast majority of values set by current sample or test applications
is much too small for subsystems like ACPI, which results in the
application not being able to run on such boards.
To solve this situation, we introduce support for subsystems to specify
their own custom system heap size requirement. Subsystems do
this by defining Kconfig options with the prefix HEAP_MEM_POOL_ADD_SIZE_.
The final value of the system heap is the sum of the custom
minimum requirements, or the value existing HEAP_MEM_POOL_SIZE option,
whichever is greater.
We also introduce a new HEAP_MEM_POOL_IGNORE_MIN Kconfig option which
applications can use to force a lower value than what subsystems have
specficied, however this behavior is disabled by default.
Whenever the minimum is greater than the requested value a CMake warning
will be issued in the build output.
This patch ends up modifying several places outside of kernel code,
since the presence of the system heap is no longer detected using a
non-zero CONFIG_HEAP_MEM_POOL_SIZE value, rather it's now detected using
a new K_HEAP_MEM_POOL_SIZE value that's evaluated at build.

When a TCP connection is established, if there is no data exchange
between the two parties within the set time, the side that enables
TCP Keep-alive will send a TCP probe packet with the same sequence
number as the previous TCP packet. This TCP probe packet is an empty
ACK packet (the specification recommends that it should not contain
any data, but can also contain 1 nonsense byte, such as 0x00.). If
there is no response from the other side after several consecutive
probe packets are sent, it is determined that the tcp connection has
failed, and the connection is closed.

Fix two issues with net tcp command:
* The `net tcp` commands are still based on net_context API. For TCP,
the API caller (net shell) should add one extra reference to the
allocated net context, to prevent premature context release in case of
connection teardown. Currently that was not the case, and the context
was released too early, resulting in missing final ACK from the Zephyr
side on connection close.
* The net context API should not be called from the registered connect
callback, as this creates a temporary deadlock situation. The
net_context_connect() function blocks until the connection is
established, or an error or timeout occurs. For that time the
net_context mutex is being locked. In case of connection error (for
example after receiving RST packet) the connect callback is called,
indicating an error. If we try to call net_context API from within, a
deadlock situation takes place, as the context mutex is still locked
by the net_context_connect() (called from the shell thread). This
blocks the further execution of the TCP stack and can result in an
unexpected behavior (like for example retransmitting the SYN packet,
which takes place from yet another thread, TCP work queue).
Fix this, by releasing the net context not from the callback directly,
but based on the return value from net_context_connect().

This commits adds support for the SO_REUSEPORT socket option.
The implementation follows the behavior of BSD and tries to also follow
the specific additional features of linux with the following
limitations:
* SO_REUSEADDR and SO_REUSEPORT are not "the same" for client sockets,
as we do not have a trivial way so identify a socket as "client"
during binding. To get the Linux behavior, one has to use SO_REUSEPORT
with Zephyr
* No prevention of "port hijacking"
* No support for the load balancing stuff for incoming
packets/connections
There is also a new Kconfig option to control this feature, which is
enabled by default if TCP or UDP is enabled.

This commit adds support for the SO_REUSEADDR option to be enabled for
a socket using setsockopt(). With this option, it is possible to bind
multiple sockets to the same local IP address / port combination, when
one of the IP address is unspecified (ANY_ADDR).
The implementation strictly follows the BSD implementation and tries to
follow the Linux implementation as close as possible. However, there is
one limitation: for client sockets, the Linux implementation of
SO_REUSEADDR behaves exactly like the one for SO_REUSEPORT and enables
multiple sockets to have exactly the same specific IP address / port
combination. This behavior is not possible with this implementation, as
there is no trivial way to identify a socket to be a client socket
during the bind() call. For this behavior, one has to use the
SO_REUSEPORT option in Zephyr.
There is also a new Kconfig to control this feature similar to other
socket options: CONFIG_NET_CONTEXT_REUSEADDR. This option is enabled by
default if TCP or UDP are enabled. However, it can still be disabled
explicitly.

Releasing the lock before notifying condvar led to a race condition
between a thread calling k_condvar_wait to wait for a condition variable
and another thread signalling for this same condition variable. This
resulted in the waiting thread to stay pending and the handle to it
getting removed from the notifyq, meaning it couldn't get woken up
again.

to fail and then the socketpair is freed but after that the remote

buffer size), with the fix issue is not seen.

Modify the signature of the k_mem_slab_free() function with a new one,
replacing the old void **mem with void *mem as a parameter.
The following function:
void k_mem_slab_free(struct k_mem_slab *slab, void **mem);
has the wrong signature. mem is only used as a regular pointer, so there
is no need to use a double-pointer. The correct signature should be:
void k_mem_slab_free(struct k_mem_slab *slab, void *mem);
The issue with the current signature, although functional, is that it is
extremely confusing. I myself, a veteran Zephyr developer, was confused
by this parameter when looking at it recently.
All in-tree uses of the function have been adapted.

The option provides control of the use of CID with the `setsockopt()`
function. The value provided can disable, enable, and control whether to
provide a CID to the peer. It uses a random self CID (if told to provide
one to the peer) unless TLS_DTLS_CID_VALUE set previously.

if any.

bidirectional or one way.
