f43e4e0637 Bluetooth: controller: Fix assert on peer unknown rsp
Fixed an assert when peer responded with unknown rsp to
slave feature request when an existing another control
procedure was in progress.

This assert happened with a BT v4.0 peer implementation that
was performing a channel map update and local controller
initiated a slave feature request, receiving an unknown

d3862d7b39 Bluetooth: mesh: Clear link TX when ACK arrived on it
Without this fix there is an issue when doing PB-ADV provisioning
with PTS. We keep retransmitting Public Key which is ACKed by PTS and
this leads to transaction timeout as PTS does not send confirm probably
because it keep receiving PK from us.

This patch also makes sure that transaction id is between 0x80 - 0xFF

38b148023e Bluetooth: controller: Fix assert on connection establishment
Fixes an assert during connection establishment when the
initiator overflows the initiator window in time while
sending the CONNECT_IND PDU. The actual window is one low
frequency tick less, hence corrected the check that permits
the transmission of CONNECT_IND PDU inside the initiator
window.

Symptom was, stopping of the scanner's ticker succeeds on
connection establishment, but next interval prepare was
already run when continuous scanning was used, breaking the
design, hence there was an assert.

header to ssl_context and then putting it back in front of the

Note that this IP header is not used by net_app when the packet

caa377943a net: http: fix avoiding timeout on HTTP requests w/o body
The original commit 8ebaf29927 ("net: http: dont timeout
on HTTP requests w/o body") was intended to handle a case
where an HTTP response had been retrieved from the server but
the HTTP parser couldn't meet the criteria for calling
"on_message_complete".  For example, a POST to a REST API
where the server doesn't return anything but an HTTP
status code.

It was a really bad idea to check a semaphore count.  There
is a lot of kernel logic built into semaphores and how the
count is adjusted.  The assumption that the value is 0
after the k_sem_give() is incorrect.  It's STILL 0 if
something is pending with a k_sem_take().  By the time
k_sem_give() is done executing the other thread has now
been kicked and the count is back to 0.

This caused the original check to always pass and in turn
breakage was noticed in the http_client sample.

Let's do this the right way by setting a flag when
on_message_complete is called and if that flag is not set
by the time we reach recv_cb, let's give back the semaphore
to avoid a timeout.

d42af5914e net: lwm2m: ignore optional resource when not implmeneted
Per LwM2M specification 7.3.2.4, "Optional Resources MAY be conveyed
in the "New Value" parameter as well; the LwM2M Client MAY ignore the
optional resources it doesn't support."

Update TLV/JSON writer to ignore error when object fields are not
found (treated as optional resource). This will allow the resources
supported being written.

22b11ba8fe net: lwm2m: define a CREATE operation
Prior to this patch, a CREATE operation was handled as a WRITE operation
after the object instance was created.  This becomes problematic when
handling of optional resources differs between these 2 operations.

Let's introduce an actual CREATE operation and use it later to create
these differences.

75016c7b97 net: lwm2m: fix resource not found error code in format writers
We are returning EINVAL from content format write ops when an object
field definition is not found (an optional field which is not
implemented).  Instead, return ENOENT which lets the LwM2M engine
know to send ZOAP_RESPONSE_CODE_NOT_FOUND to the LwM2M server at the
end of handle_request().

NOTE: This behavior is not correct when we call the writer right after
a CREATE operation where the data is assigned to resources for the
first time.  This case will be handled in a follow-up patch once we're
able to distinguish between a WRITE and a CREATE in the write op
handler.

cf43be1a2e Bluetooth: Increase CONFIG_BT_HCI_TX_STACK_SIZE for BT_SPI
Older value of 256 was introduced in 1.7 times. Testing on
BOARD=96b_carbon with 2 weeks old codebase however showed that TX
thread stack however can grow to 324 bytes. Finally, with the
latest master, following stacks are reported on BLE disconnect
(with CONFIG_INIT_STACKS enabled):

rx stack (real size 1024): unused 452 usage 572 / 1024 (55 %)
tx stack (real size 384):  unused 16  usage 368 / 384 (95 %)

Two outcomes:

1. TX stack needs increase.
2. Over time, the stack usage grows, plus variations in SPI
drivers should also be taken into account.

So, increase the stack size to 416 bytes, to leave some headroom
beyond the immediate values seen on 96b_carbon.

8ebaf29927 net: http: dont timeout on HTTP requests w/o body
A TCP FIN message is passed on to user apps as a tcp_received_callback
with a NULL pkt parameter.  This means the connection is closing and
the app should do whatever cleanup it needs as there will be no further
callbacks for the current TCP connection.

Currently, if a HTTP client request doesn't receive a "body" which
the HTTP parser can use to trigger on_message_complete, then the request
will end up timing out and most apps will think an error has occurred.

Instead, let's handle the TCP FIN message and return the waiting
semaphore, leaving the app to deal with whatever has been set in the
current HTTP context response data (IE: http_status).

This fixes using HTTP client to send POST data to servers which
only respond with HTTP_OK status and no body.

specifies a host string as a part of the HTTP client request
structure, we end up sending an incorrect HTTP header due
to a missing "Host :" text.

Fix this by prepending "Host: " to the header data before
the user supplied host string.

It is also the only config in drivers/bluetooth that is in use when

allows us to restructure the drivers/kconfig code such that the entire
Bluetooth driver menu option is omitted when the BT_CONTROLLER is

Moving it will also mean that all configs in drivers/bluetooth will

c46c206f8c net: lwm2m: initial library support for LWM2M
Origin: SICS-IoT / Contiki OS
URL: https://github.com/sics-iot/lwm2m-contiki/tree/lwm2m-standalone-dtls
commit: d07b0bcd77ec7e8b93787669507f3d86cfbea64a
Purpose: Introduction of LwM2M client library.
Maintained-by: Zephyr

Lightweight Machine-to-Machine (LwM2M) is a protocol stack extension
of the Constrained Application Protocol (CoAP) which uses UDP
transmission packets.

This library was based on source worked on by Joakim Eriksson,
Niclas Finne and Joel Hoglund which was adopted by Contiki and then
later revamped to work as a stand-alone library.

A VERY high level summary of the changes made:
- [ALL] sources were re-formatted to Zephyr coding standards
- [engine] The engine portion was re-written due to the heavy reliance
  on ER-CoAP APIs which are not compatible to the Zephyr CoAP APIs as
  well as other Zephyr specific needs.
- [engine] All LWM2M/IPSO object data is now abstracted into resource
  data which stores information like the data type, length, callbacks
  to help with read/write.  The engine modifies this data directly (or
  makes callbacks) instead of all of the logic for this living in each
  object's code. (This wasn't scaling well as I was implementing
  changes).
- [engine] Related to the above change, I also added a generic set of
  getter/setter functions that user applications can call to change
  the object data instead of having to add getter/setting methods in
  each object.
- [engine] The original sources shared the engine's context structure
  quite extensively causing a problem with portability. I broke up the
  context into it's individual parts: LWM2M path data, input data and
  output data and pass only the needed data into each set of APIs.
- [content format read/writer] sources were re-organized into single
  .c/h files per content formatter.
- [content format read/writer] sources were re-written where necessary
  to remove the sharing of the lwm2m engine's context and instead only
  requires the path and input or output data specific to it's
  function.
- [LwM2M objects] re-written using the new engine's abstractions

911efb0e72 net: zoap: use message id for reply matching
In the 08 Feb 2017 V1.0 LwM2M specification page 80 mentions: in
response to a "Notify" operation for which it is not interested in
any more, the LwM2M Server can send a "Reset Message".

Leshan server sends this CoAP RST response and it does not contain
the originating message token (which is also how the packet flow looks
on page 81 of the LwM2M spec).  Using the current ZoAP sources, the
client has no way of matching back to observation which needs to be
cancelled.

Let's add a match for message ID of a reply where there is no token
to handle this case.

197e6e2ba3 Kconfig: Move BLUETOOTH_HCI_RESERVE into subsys/bluetooth/host
There are two kinds of HCI implementations. Bluetooth drivers in
 drivers/bluetooth that implement HCI by using a wired serial
 transport layer to talk to an external controller chip. And a
 bluetooth controller in subsys/bluetooth/controller that directly
 talks to an internal on-chip controller node.

Currently, when the the subsys/bluetooth/controller is used there
still exists exposed to the user a bluetooth driver configuration
menu, even though no external bluetooth driver is in use. This is due
to a dependency on certain configs in driver/bluetooth that are needed
even though no external controller is used.

This patch moves one of these configs, BLUETOOTH_HCI_RESERVE, from
drivers/bluetooth/hci/Kconfig to subsys/bluetooth/host/Kconfig such
that eventually we can omit the entire Bluetooth driver menu option.

This re-organization does not change when the config can be enabled.

19ff963693 net: tcp: Allow to explicitly manage TCP receive window
This fixes the existing situation that "if application buffers data,
it's the problem of application". It's actually the problem of the
stack, as it doesn't allow application to control receive window,
and without this control, any buffer will overflow, peer packets
will be dropped, peer won't receive acks for them, and will employ
exponential backoff, the connection will crawl to a halt.

This patch adds net_context_tcp_recved() function which an
application must explicitly call when it *processes* data, to
advance receive window.

9b3f6362e6 net: app: allow IPv6 interface init to work with late IP assigment
Some network interfaces such as bluetooth 6lowpan can start without
an assigned IP address and then later once the connection is up a
router advertisement broadcast will assign the IP address.

The net_app framework will timeout out during network init if a value

the framework to handle a missing value there and fill it in later
when the IPv6 address is added to the interface.

62a0cd246d doc: fix uses of back quotes in documentation
ReST defines interpreted text roles where text enclosed by single quotes
can be "intrepreted", for example :ref:`some name` becomes a link to
a label anywhere in the doc set named "some name", :c:func:`funcname()`
becomes a link to the API documentation for "funcname", and
:option:`CONFIG_NAME` becomes a link to, in our case, the documentation
for the generated Kconfig option.

This patch fixes uses of `some name` (without a role) by either adding
an explicit role, or changing to ``some name``, which indicates inline
code block formatting (most likely what was intended).

This is a precursor to changing the default behavior of interpreted
text to treat `some name` as :any:`some name` (as configured in
doc/conf.py), which would attempt to create a link to any available
definition of "some name".

We may not change this default role behavior, but it becomes an option
after the fixes in this patch.  In any case, this patch fixes incorrect
uses of single-quoted text (possibly introduced because GitHub's
markdown language uses single-quoted text for inline code formatting).

507852a4ad kernel: introduce opaque data type for stacks
Historically, stacks were just character buffers and could be treated
as such if the user wanted to look inside the stack data, and also
declared as an array of the desired stack size.

This is no longer the case. Certain architectures will create a memory
region much larger to account for MPU/MMU guard pages. Unfortunately,
the kernel interfaces treat both the declared stack, and the valid
stack buffer within it as the same char * data type, even though these
absolutely cannot be used interchangeably.

We introduce an opaque k_thread_stack_t which gets instantiated by
K_THREAD_STACK_DECLARE(), this is no longer treated by the compiler
as a character pointer, even though it really is.

To access the real stack buffer within, the result of
K_THREAD_STACK_BUFFER() can be used, which will return a char * type.

This should catch a bunch of programming mistakes at build time:

- Declaring a character array outside of K_THREAD_STACK_DECLARE() and
  passing it to K_THREAD_CREATE
- Directly examining the stack created by K_THREAD_STACK_DECLARE()
  which is not actually the memory desired and may trigger a CPU
  exception

This is needed for those technologies like Bluetooth or 802.15.4 which
compress the IPv6 header during send.

0ec2630882 Bluetooth: Mesh: Add initial implementation
Add an initial implementation for the Bluetooth Mesh Profile
Specification. The main code resides in subsys/bluetooth/host/mesh and
the public API can be found in include/bluetooth/mesh.h. There are a
couple of samples provided as well under samples/bluetooth and
tests/bluetooth.

The implementation covers all layers of the Bluetooth Mesh stack and
most optional features as well. The following is a list of some of
these features and the c-files where the implementation can be found:

 - GATT & Advertising bearers (proxy.c & adv.c)
 - Network Layer (net.c)
 - Lower and Upper Transport Layers (transport.c)
 - Access Layer (access.c)
 - Foundation Models, Server role (health.c & cfg.c)
 - Both PB-ADV and PB-GATT based provisioning (prov.c)
 - Low Power Node support (lpn.c)
 - Relay support (net.c)
 - GATT Proxy (proxy.c)

Notable features that are *not* part of the implementation:

 - Friend support (initial bits are in place in friend.c)
 - Provisioner support (low-value for typical Zephyr devices)
 - GATT Client (low-value for typical Zephyr devices)

4334144caa net: context: Fix use of k_delayed_work_cancel with SYN backlog
This patch fixes a regression which the original patch introducing
this code (improving concurrent connection handling) had on
*sequential* connection handling. Without this patch, with the
default CONFIG_NET_TCP_BACKLOG_SIZE of 1, after each connection
request, there was 1s (ACK timeout) "dead time" during which new
connection wasn't ptocessed.

This is because k_delayed_work_remaining_get() was checked the
wrong way. But there's no need to use k_delayed_work_remaining_get()
at all, instead just call k_delayed_work_cancel() and dispatch on
its return code.

Note that there's still a problem of synchronizing access to
the global array tcp_backlog, as worker (which modifies it) may
preempt packet handling code (which also modifies it).

ccb9c844b5 net: ipv6: Increase default multicast address count to 3
Usually it is not enough to have just one IPv6 multicast
address defined for the network interface. So allocate three
IPv6 multicast addresses for the network interface as IPv6
by default uses multicast a lot. This hopefully will avoid
some mysterious errors if the addresses run out.

Note that this will increase memory usage a bit so you might
need to lower the count in your conf file if memory is low.

e663c5df51 net: tcp: Add FIN timer when doing active close
The commit 210c30805b ("net: context: Close connection fast
if TIME_WAIT support is off") was not a proper way of closing
the connection. So if Zephyr closes the connection (active close),
then send FIN and install a timer that makes sure that if the peer
FIN + ACK is lost, we close the connection properly after a timeout.

42c2b2ea81 Bluetooth: GATT: Rework Service Changed indications
There could be situations where many services are changed in a row which
would cause k_sem_take to block on the second change, but if the calling
thread is actually the RX thread then this will deadlock since the RX
thread is the one processing the confirmations of indications and it is
blocked k_sem_give is never called.

To solve this the services changes are now offloaded to the system wq
and the code will attempt to consolidate the range being changed so only
one indication is send. If for some reason another changes is caused
while confirmation is pending we just reschedule it to run later to
avoid blocking the system wq in the same way.

65a9d2a94a kernel: make K_.*_INITIALIZER private to kernel
Upcoming memory protection features will be placing some additional
constraints on kernel objects:

- They need to reside in memory owned by the kernel and not the
application
- Certain kernel object validation schemes will require some run-time
initialization of all kernel objects before they can be used.

Per Ben these initializer macros were never intended to be public. It is
not forbidden to use them, but doing so requires care: the memory being
initialized must reside in kernel space, and extra runtime
initialization steps may need to be peformed before they are fully
usable as kernel objects. In particular, kernel subsystems or drivers
whose objects are already in kernel memory may still need to use these
macros if they define kernel objects as members of a larger data
structure.

It is intended that application developers instead use the
K_<object>_DEFINE macros, which will automatically put the object in the
right memory and add them to a section which can be iterated over at
boot to complete initiailization.

There was no K_WORK_DEFINE() macro for creating struct k_work objects,
this is now added.

k_poll_event and k_poll_signal are intended to be instatiated from
application memory and have not been changed.

expiry.

In the scan_adv sample, with continuous scanning, an
advertiser would pre-empt it, but if the advertiser skipped
its event without aborting the scanner, the scanner is hung
with its rx window without a timeout, and HCI command to
stop the advertiser will wait forever to complete.

3c23c6f53d Bluetooth: controller: Fix assert due to stale tick count
Fixed assert due to stale tick count in role event
preparation. This happens when ticker timeout expiry is
delayed from the requested realtime anchor, due to thread
mode processing overheads and occurring interrupts therein,
if any, that added a delay between requested anchor tick
and actual scheduling for the requested ticker timeout.

The assert is reproduced in bt shell by starting advertising
and following it with continuous scanning (interval 2.5ms,
window 2.5ms), on nRF51x. If the overheads and/or a
advertiser event delayed the scheduling of scanner by over
2.5ms, then the preparation of scanner asserted.

The assert has been fixed by checking for stale tick count
at expiry in role event preparation and skip the event
gracefully.

in_addr_t
    An unsigned integral type of exactly 32 bits.

[] the in_addr structure [] includes at least the following member:

in_addr_t      s_addr

In other words, POSIX requires s_addr to be a single integer value,
whereas Zephyr defines it as an array, and then access as s_addr[0]
everywhere. Fix that by following POSIX definition, which helps to
port existing apps to Zephyr.

Fixed also the debug prints which print extra \n which looks

This commit does not enable mbedtls debugging, it just makes it
possible to output mbedtls debug prints. In order to get mbedlts
debug prints one needs to do this:
* set DEBUG_THRESHOLD to >0 in http_server.c
* enable CONFIG_NET_DEBUG_HTTP in project config file
* enable MBEDTLS_DEBUG_C in mbedtls config file (see file pointed
  by CONFIG_MBEDTLS_CFG_FILE option)

If we do not receive last ACK when the connection is tore down,
then do not wait forever as that would eat all the resources in
the network stack. So when we enter the LAST_ACK state, we setup
a timer that will unref the connection if the last ACK is not
received.

Without change to add ACK to FIN, invalid TCP packet is generated,
where ack sequence number is non-zero. Without adjusting sequence
number as done, ACK which we send in response to peer's FIN/ACK is
not recognized by peer, and peer keeps retransmitting its FIN/ACK.

can be resource intensive, do it after we have verified that
there is a connection handler for this connection.

7a1a9a7946 net: tcp: Handle retransmitted packets from peer.
When we receive a packet with the sequence we already seen (and
processed), the most likely cause of it is that our ACK was lost,
and peer has to retransmit that packet. Then, we should just ACK
it, because otherwise peer will retransmit it again and again,
falling into exponential backoff and hosing the entire TCP
connection.

This makes changes to send_ack(), adding a flag to force sending
an ACK regardless of its cached status, and remove inline modifier,
as the function is big and called from many places.

We must check if we receive RST in any of the TCP states.
If we do not do this, then the net_context might leak as it
would never be released in some of the states. Receiving RST
in any TCP state is not described in TCP state diagram but is
described in RFC 793 which says in chapter "Reset Processing"
that system "...aborts the connection and advises the user and
goes to the CLOSED state."

We need to also validate the received RST and accept only those
TCP reset packets that contain valid sequence number.

The validate_state_transitions() function is also changed to
accept CLOSED state transition from various other states.

7ebe7da736 Bluetooth: controller: Controller to Host flow control
The Bluetooth Specification allows for optional Controller to Host flow
control based on the same credit-based mechanism as the Host to
Controller one. This is particularly useful in 2-chip solutions where
the Host and the Controller are connected via a physical link (UART, SPI
or similar) where the Host is sometimes required to ask the Controller
to throttle its data traffic while still making sure that relevant
events get through the line.

This implementation is based on a simple queue of pending events and
data that is populated whenever the Controller detects that the Host is
out of buffers and then emptied whenever the Host notifies the
Controller that is ready to receive data again. Events relevant to the
connections are also queued to preserve the order of arrival.

At this point the Controller ignores the connection handle sent by the
Host and treats all connections equally, and it also queues events even
for connections that have no data pending in the queue. Both this items
can be improved if necessity arises.

Note that Number of Completed Packets will still flow freely from the
Controller to the Host regardless of the pending ACL data packets, which
might lead to inconsistencies in the sequential order of certain
operations that include bi-directional data transfer.

fa5503fb44 net/mqtt: use rlen to calculate # of QoS items in SUBACK packet
The data->len of an inbound netbuf can be larger than a single
MQTT packet.  For instance when a PINGRESP is also included
in the same netbuf.  For this reason we should not be using
the data->len to determine how large the rest of the MQTT data is.

Specific Example: we've seen in testing that PINGRESP packets
can be included with a SUBACK packet in the same netbuf. Under
this case the current code uses the data->len incorrectly and
tries to find 3 QoS elements for the SUBACK packet when there
is only 1 (the rest of the data is for PINGRESP).

NOTE: A larger patch to iterate through the netbuf data parsing
individual MQTT packets will be needed to fix the MQTT subsys.
This patch only corrects the SUBACK parsing.

25307d5331 net: net_pkt_append: Refactor to return length of data actually added
For stream-based protocols (TCP), adding less data than requested
("short write") is generally not a problem - the rest of data can
be sent in the next packet. So, make net_pkt_append() return length
of written data instead of just bool flag, which makes it closer
to the behavior of POSIX send()/write() calls.

There're many users of older net_pkt_append() in the codebase
however, so net_pkt_append_all() convenience function is added which
keeps returning a boolean flag. All current users were converted to
this function, except for two:

samples/net/http_server/src/ssl_utils.c
samples/net/mbedtls_sslclient/src/tcp.c

Both are related to TLS and implement mbedTLS "tx callback", which
follows POSIX short-write semantics. Both cases also had a code to
workaround previous boolean-only behavior of net_pkt_append() - after
calling it, they measured length of the actual data added (but only
in case of successful return of net_pkt_append(), so that didn't
really help). So, these 2 cases are already improved.

This adds a new event type to the kernel event logger that tracks

It's the only event type that contains "subevents" and thus has a
non-void parameter in their respective _sys_k_event_logger_*()
function.  Luckily, as isn't the case with other events (such as IRQs
and thread switching), these functions are called from
platform-agnostic places, so there's no need to worry about changing
the assembly guts.

This is the first patch in a series adding support for better real-time

We need to set the connect_cb for the context before sending SYN packet.
This is required if we have a loopback connection in which case everything
is happening more or less synchronously and the connect_cb would not be
called in this case because its value would still be null.
For remote network connections this patch makes no difference.

bf964cdd4c net: Renaming net nbuf API to net pkt API
There have been long lasting confusion between net_buf and net_nbuf.
While the first is actually a buffer, the second one is not. It's a
network buffer descriptor. More precisely it provides meta data about a
network packet, and holds the chain of buffer fragments made of net_buf.

Thus renaming net_nbuf to net_pkt and all names around it as well
(function, Kconfig option, ..).

Though net_pkt if the new name, it still inherit its logic from net_buf.
'
This patch is the first of a serie that will separate completely net_pkt
from net_buf.

to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.

We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with

045f076e5e Bluetooth: Use event masks instead of bits in controller and host
To avoid having to define a BIT64() macro in a public namespace, use
instead masks directly instead of bits, and also refactor the host code
so that it uses those instead of the earlier byte array with hardcoded
indices and masks.

819d3ae9c9 Bluetooth: AT: use explicit unsigned char to avoid array subscript error
If we use newlib the isdigit (and other similar functions) return an
error as char can possibly be viewed as signed:

usr/include/ctype.h:57:54: error: array subscript has type ‘char’ [-Werror=char-subscripts]
 #define __ctype_lookup(__c) ((__ctype_ptr__+sizeof(""[__c]))[(int)(__c)])

Being explicit about the char being unsigned char deals with this.

The main issue is that after the latest update to TinyCrypt the
ecc_make_key() API expects a twice as big random number. Fix this, but
also move the variables to the static context since we're limiting one
HCI command at a time. Also place the variables in a union based on
their temporal dependencies. Thanks to this, we can now further reduce
the ECC stack size by 40 bytes (on ARM this then reports 12 bytes of
unused stack after key-pair generation and DHKey calculation).

Disabling this feature will lead to overlapping role in

9028e8e75b Bluetooth: ECC: Fix command status emission from wrong thread
HCI drivers are obliged to send HCI Command Status/Complete events
from a separate context than all other data, however the ECC wrapper
was violating this rule (sending everything from the same ECC thread).
This could lead to a deadlock if e.g. the ECC API user decides to
generate a DHKey from the same callback that it got notified of local
key-pair generation.

The obvious solution is to emit the Command Status directly from the
send function, before passing the command to be processed by the ECC
therad (through a k_fifo). However, this is not quite so simple since
bt_buf_get_cmd_complete() reuses the original command buffer, meaning
we'd loose the original parameters after sending a Command Status.

To work around this limitation with bt_buf_get_cmd_complete() we stop
passing the command buffer to the thread and instead store the
parameters in static variables and do the thread communication using
flags and a semaphore. One side effect is that only one command can be
pending at a time, however that works out fine for all of the users of
ECC.

A nice side effect of moving some things to static variables is that
we end up reducing call stack usage in the ECC thread, allowing it to
be shrunk by 180 bytes (verified to be sufficient for both ARM and
x86 boards).

646726518f Bluetooth: controller: Kconfig for advanced event preparation
Added Kconfig option to enable advanced event preparation
feature.

Enables advanced event preparation offset ahead of radio
tx/rx, taking into account predictive processing time
requirements in preparation to the event, like control
procedure handling and CPU execution speeds. Crystal
oscillator is retained between closely spaced consecutive
radio events to reduce the overall number of crystal
settling current consumptions.

This feature maximizes radio utilization in an average role
event timeslice when they are closely spaced by using a
reduced offset between preparation and radio event.

By disabling this feature, the controller will use a
constant offset between the preparation and radio event. The
controller will toggle crystal oscillator between two
closely spaced radio events leading to higher average
current due to increased number of crystal settling current
consumptions.

19d740c162 Bluetooth: monitor: Drop data instead of holding IRQ lock for long
The IRQ lock should never be held for long periods of time. Instead of
using the IRQ lock to prevent monitor protocol corruption simply drop
the data. Follow-up patches will add additional drop count tracking so
that these get reported properly over the protocol.

a745832dc4 net: Elaborate output of net_nbuf_print_frags() to be more useful.
Following changes are made:

1. Output using NET_INFO logging level. This function is not part of
automatic logging, and must be called explicitly by a user application.
But if it outputs using NET_DEBUG, then DEBUG level needs to be
enabled, and the output of this function will be drowned in logging
spam. So, let user to enable just INFO level.

2. Show entire structure of the fragment chain, *including* the head
net_buf which holds net_nbuf structure. It is numbered as -1 in the
output to preserve existing order (and not change existing size
calculations).

3. Show owning pool (and its properties, like buffer size/user_data
size) for each buffer.

4. Check for NULL pointer, e.g. for convenience of calling directly
from net_context receive callback (which will be called with NULL
on TCP peer closed connection event).

With these changes, a newcomer from one look at the output of this
function will be able to have a clear basic picture of network
buffer management in Zephyr, and recurring user will be able to
recall any details at once.

542c2b93d0 subsys: console: Add pull-style console API support.
This change introduces console_getchar() and console_getline() API
calls which can be used to get pending console input (either one
char or whole line), or block waiting for one. In this regard, they
are similar to well-known ANSI C function getchar/gets/fgets, and
are intended to ease porting of existing applications to Zephyr, and
indeed, these functions (shaped as an external module) are already
used by few applications.

The implementation of the functions is structured as a new "console"
subsystem. The intention is that further generic console code may be
pulled there instead of being in drivers/console/. Besides the
functions themselves, initialization code and sample applications
are included.

At this time, there're may limitations of how these functions can
be used. For example, console_getchar() and console_getline() are
mutually exclusive, and both are incompatible with callback
(push-style) console API (and e.g. with console shell subsystem
which uses this API). Again, the intention is to make a first step
towards refactoring console subsystem to allow more flexible
real-world usage, better reusability and composability.

5e115ba935 net/ieee802154: Provide the means to create secured data frames
Take into account the current security context to compute the header
