I think people might be reading differences into 'if' and 'depends on'
that aren't there, like maybe 'if' being needed to "hide" a symbol,
while 'depends on' just adds a dependency.
There are no differences between 'if' and 'depends on'. 'if' is just a
shorthand for 'depends on'. They work the same when it comes to creating
implicit menus too.
The way symbols get "hidden" is through their dependencies not being
satisfied ('if'/'depends on' get copied up as a dependency on the
prompt).
Since 'if' and 'depends on' are the same, an 'if' with just a single
symbol in it can be replaced with a 'depends on'. IMO, it's best to
avoid 'if' there as a style choice too, because it confuses people into
thinking there's deep Kconfig magic going on that requires 'if'.
Going for 'depends on' can also remove some nested 'if's, which
generates nicer symbol information and docs, because nested 'if's really
are so simple/dumb that they just add the dependencies from both 'if's
to all symbols within.
Replace a bunch of single-symbol 'if's with 'depends on' to despam the
Kconfig files a bit and make it clearer how things work. Also do some
other minor related dependency refactoring.
The replacement isn't complete. Will fix up the rest later. Splitting it
a bit to make it more manageable.
(Everything above is true for choices, menus, and comments as well.)
Detected by tweaking the Kconfiglib parsing code. It's impossible to
detect after parsing, because 'if' turns into 'depends on'.

Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).
Go for the most common style:
- Indent properties with a single tab, including for choices.
Properties on choices work exactly the same syntactically as
properties on symbols, so not sure how the no-indentation thing
happened.
- Indent help texts with a tab followed by two spaces
- Put a space between 'config' and the symbol name, not a tab. This
also helps when grepping for definitions.
- Do '# A comment' instead of '#A comment'

Handle this corner case with TCP connection closing:
1) Client A connects, it is accepted and can send data to us
2) Client B connects, the application needs to call accept()
before we will receive any data from client A to the application.
The app has not yet called accept() at this point (for
whatever reason).
3) Client B then disconnects and we receive FIN. The connection
cleanup is a bit tricky as the client is in half-connected state
meaning that the connection is in established state but the
accept_q in socket queue contains still data which needs to be
cleared.
4) Client A then disconnects, all data is sent etc
The above was not working correctly as the system did not handle the
step 3) properly. The client B was accepted in the application even
if the connection was closing.

Use the newest version of the OpenThread project, as updated in
https://github.com/zephyrproject-rtos/openthread/pull/2.
Introduce the following fixes along with the update (they're squashed to
retain bisectability of OT samples):
* Update configs and flags used
Some OT configs were renamed, some new were introduced that Zephyr port
needs to set.
* Add entropy platform driver
OpenThreads `random` platform subsystem was replaced with `entropy`
subsystem which is supposed to serve as an entropy source for the
generic OpenThread's random generator.
* Halt OT thread when OT command is processed
OpenThread can currently be processed from two threads - a
genuine OpenThread thread and shell thread, which processes CLI
commands. This could cause trouble, when context was switched
during OT command processing (i.e. switched to process an incomming OT
message, while still in unfinished command handler).
In result, it was not possible to turn the commissioner role on via
CLI, as the commissioner petition response was handled before the
Commissioner::Start function finished its execution (if the
petitioner is also the network leader, all messages are passed
internally within the stack).
Fix this by suspending the OT thread for the time of an OT command
processing.

System call arguments, at the arch layer, are single words. So
passing wider values requires splitting them into two registers at
call time. This gets even more complicated for values (e.g
k_timeout_t) that may have different sizes depending on configuration.
This patch adds a feature to gen_syscalls.py to detect functions with
wide arguments and automatically generates code to split/unsplit them.
Unfortunately the current scheme of Z_SYSCALL_DECLARE_* macros won't
work with functions like this, because for N arguments (our current
maximum N is 10) there are 2^N possible configurations of argument
widths. So this generates the complete functions for each handler and
wrapper, effectively doing in python what was originally done in the
preprocessor.
Another complexity is that traditional the z_hdlr_*() function for a
system call has taken the raw list of word arguments, which does not
work when some of those arguments must be 64 bit types. So instead of
using a single Z_SYSCALL_HANDLER macro, this splits the job of
z_hdlr_*() into two steps: An automatically-generated unmarshalling
function, z_mrsh_*(), which then calls a user-supplied verification
function z_vrfy_*(). The verification function is typesafe, and is a
simple C function with exactly the same argument and return signature
as the syscall impl function. It is also not responsible for
validating the pointers to the extra parameter array or a wide return
value, that code gets automatically generated.
This commit includes new vrfy/msrh handling for all syscalls invoked
during CI runs. Future commits will port the less testable code.

Formatting a float32/64 value for plain text is broken.
Example for 32bit: val1=0 and val2=500000 is equivalent to 0.5
Current formatter was using %d.%d (%lld.%lld for 64bit) so
exported value was 0.500000 (or 0.5)
To fix this, for val2 use a zero-padded formatter for the maximum
length of each bit length (6 for 32bit and 9 for 64bit), and then
remove the zero characters at the end of the string.
Notes re: handling of val1/val2 signs:
- eliminate potential negative sign when converting val2 to avoid:
a value like: 0.-5
- use negative val2 when val1 is 0 to fix small negative handling
such as -0.5

Several problems with memset usage in the LwM2M subsystem were
identified:
- Every single object that can have multiple instances is using
memset to initialize static resource data during init. This data
will already be set to 0 because it is static, so the memset
statements are unneeded.
- Instead of using memset during object init which is only called
one time during kernel startup, let's add a memset to the
object create function to ensure the resource data is cleared out.
It could have been used prior and then released via a DELETE op.
- the IPSO Timer object was setting a lot of data structure members
to 0 in the create function. Let's do 1 memset on the entire
structure and then only the non-zero values afterward.

LwM2M allows for multiple instance resources such the power source
resources in the device object. These types of resources have
always been very hard to work with, and frankly were poorly
implemented.
This led to other issues where it was very hard to have
non-sequential resource instances, and each resource of this type
needed special getter / setter methods such as:
lwm2m_device_add_pwrsrc()
lwm2m_device_set_pwrsrc_voltage_mv()
Going forward, as more LwM2M objects are implemented this just
doesn't scale well.
To fix this:
- split the resource instance data out from the resource data.
This includes the data pointer information and resource
instance id.
- add resource id and resource instance id to the event callback
functions so user's can see in more detail what resources and
resource instances are being handled.
- allow generic functions like lwm2m_engine_get_*() and
lwm2m_engine_set_*() to access resource instance data.
- adjust object resource initialization macros to map resource
instances to resources at the time of object instance
creation.
- fix up the lwm2m_client as a reflection of all of these changes.

This fixes an issue where if timestamp == service_due_timestamp,
we don't call the periodic service. Then the following call to
engine_next_service_timeout_ms() returns 0 because the service
is still due and lwm2m_engine_service() is called again.
This process repeats several times until the value of
k_uptime_get() changes and then the work is finally handled.
Previously, the resolution of k_uptime_get() was in ms. A recent
change to this API defaults Zephyr so that the resolution is
set via CONFIG_SYS_CLOCK_TICKS_PER_SEC (default 100).
This means the value of k_uptime_get() only changes every 10ms.

"It's a Trap!" -- Admiral Ackbar
When moving to the BSD-socket APIs, the original thread running LwM2M
periodic services such as observes and lifetime updates, was replaced
with a re-occuring workqueue job. To save the overhead of creating a
new thread, I used the system workqueue for these jobs.
This was a mistake. If these jobs hit a semaphore or wait for some
reason, it cannot be prempted due to the priority of the system work
queue.
Let's instead add this service handling to the thread that we already
use for polling sockets. This also removes a configuration issue where
the system workqueue stack size needed to be increased. This can now
be adjusted via the LWM2M_ENGINE_STACK_SIZE knob.
Directly fixes semaphore usage in the socket-based DNS code.
This was introduced as a bugfix for non-responsive DNS server hanging
the Zephyr device forever. However, this probably fixes randomly
seeming hangs on the device.

TCP context is effectively owned by both application and the stack:
stack may detect that peer closed/aborted connection, but it must
not dispose of the context behind the application back. Likewise,
when application "closes" context, it's not disposed of immediately,
there's yet closing handshake for stack to perform.
This effectively means that TCP contexts have refcount of 2 when
they're created. Without this change, following situation is
possible: peer opens connection, an app get a context (or socket)
via accept, peer sends data, closes connection. An app still holds
a reference to connection, but stack may dispose of context, and
even reuse it for a new connection. Then application holds a reference
to either free, or completely different context.
This situation was very clearly and 100% reproducible when making
Zephyr port of open62541 library, which works in async manner using

subsys/net/lib/lwm2m/Kconfig.ipso is 'source'd within an 'if LWM2M', in

The 'depends on NET_IPV4' and 'depends on NET_L2_OPENTHREAD' are within
corresponding 'if's in the same file.
'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. Dependencies on menus work similarly. There are no
"conditional includes" in Kconfig, so 'if FOO' has no special meaning
around a source. Conditional includes wouldn't be possible, because an

to symbols not defined yet.
Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.

Initial implementation of IPSO Timer object #3340
Based on: http://www.openmobilealliance.org/tech/profiles/lwm2m/3340.xml
"This IPSO object is used to time events and actions, using patterns
common to industrial timers. A POST to the trigger resource or On/Off
input state change starts the timing operation, and the timer
remaining time shows zero when the operation is complete. The
patterns supported are One-Shot (mode 1), On-Time or Interval
(mode 2), Time delay on pick-up or TDPU (tmode 3), and Time Delay
on Drop-Out or TDDO (mode 4). Mode 0 disables the timer, so the output
follows the input with no delay. A counter is provided to count
occurrences of the timer output changing from 0 to 1. Writing a value
of zero resets the counter. The Digital Input State resource reports
the state of the timer output."

struct timeval is per POSIX defined in sys/time.h, but that also
allowed to pull sys/select.h (and indeed, it does with native_posix),
which then starts to conflict with out select implementation (if
NET_SOCKETS_POSIX_NAMES is defined, and many samples/tests have it).
So, for now follow the existing route of duplicating all definitions
needed by our code in namespaced manner. Things like struct timeval
usage will need to be revisited later, when we'll want socket
subsystem to work with POSIX subsystem, but that's a separate deep
matter.

It's implemented on top of poll() anyway, and the current
implementation of fd_set uses array of fd's underlyingly, which
leads to O(n) complexity for FD_SET() and friends.
The purpose of select() implementation is to allow to perform
proof-of-concept port of 3rd-party code to Zephyr quickly. For
efficiency, poll() should be used instead.

net_buf_linearize() used to clear the contents of output buffer,
just to fill it with data as the next step. The only effect that
would have is if less data was written to the output buffer. But
it's not reliable for a caller to rely on net_buf_linearize() for
that, instead callers should take care to handle any conditions
like that themselves. For example, a caller which wants to process
the data as zero-terminated string, must reserve a byte for it
in the output buffer explicitly (and set it to zero).
The only in-tree user which relied on clearing output buffer was
wncm14a2a.c. But either had buffer sizes calculated very precisely
to always accommodate extra trailing zero byte (without providing
code comments about this), or arguably could suffer from buffer
overruns (at least if data received from a modem was invalid and
filled up all destination buffer, leaving no space for trailing
zero).

Currently OpenThread commands have to be prefixed in the shell by "ot
cmd", for example "ot cmd state". With the new shell, it is possible to
remove one subcommand level and change it to "ot state".
At the same time validate the number of arguments using
SHELL_CMD_ARG_REGISTER and improve the help message.

Following the introduction of the new shell, the OpenThread shell
wrapper is not well integrated. It outputs the answer to a command using
printk(), which is not necessarily using the same device than the shell
if "zephyr,console" does not match "zephyr,shell-uart".
OpenThread calls the otConsoleOutputCallback() function to output the
answer to the shell. It can provide a callback argument, but defined
when OpenThread is initialized, not when the command is submitted.
Workaround that by taking a copy of the shell argument in a static
variable and use it for the call to shell_fprintf(). It is not perfect
if two or more shells issue concurrent commands, but is already an
improvement compared to printk().

As extend fdtable usage to more cases, there regularly arises a need
to forward ioctl/fcntl arguments to another ioctl vmethod, which is
complicated because it defined as taking variadic arguments. The only
portable solution is to convert variadic arguments to va_list at the
first point of entry from client code, and then pass va_list around.
To facilitate calling ioctl with variadic arguments from system code,
z_fdtable_call_ioctl() helper function is added.

This commit reworks socket poll implementation to support multiple
socket implementations.
To achieve that, two ioctl poll helper requests were added:
ZFD_IOCTL_POLL_PREPARE and ZFD_IOCTL_POLL_UPDATE. The poll
implementation calls ioctl with these requests for each socket
requested in the fds table.
The first request is responsible for preparing k_poll_event objects
for specific socket. It can request to skip waiting in k_poll by
returning EALREADY through errno.
The latter request is responsible for processing outcome of k_poll for
each socket. It can request to retry the k_poll by returning EAGAIN
through errno.

Second, currntly implemented "options" in command handlers options are

Implements setsockopt() for the socket offload driver
to process the TLS tags sent in via the Zephyr setsockopt() API,
when CONFIG_NET_SOCKETS_SOCKOPT_TLS is chosen.
For each tag, the credential filenames are retrieved and
set via SimpleLink's sl_SetSockOpt() API.
Also, creates a new KConfig option for TLS_CREDENTIAL_FILENAMES.
This new option is used by apps/protocols to add TLS credentials
via filenames referring to the actual content stored on a secure
file system or flash.
Handles the IPPROTO_TLS_* socket protocol families in the
socket() offloaded API.
This was validated on the cc3220sf_launchxl with the http_get sockets
sample, with the globalsign_r2.der file loaded to secure flash via
the TI Uniflash tool, and using the TI Catalog of known good
root CA's.

During the retransmit cycle we take ref on the outgoing packet,
only to immediately unref it. Originally, this was to make sure
the net_context handling didn't get rid of the packet when

in danger of going to 0 at this point in the code, so the
added ref handling is useless.

nRF5 SDK, introducing the following features:
* transport independent MQTT logic, with support for multiple transports
* support for multiple MQTT versions (3.1.0 and 3.1.1 supported)
* single event handler - no need to keep callback array in RAM
* automatic send of Ping Requests, for connection keep-alive
* message/event parameters wrapped into strucutres - easier extension
for future MQTT versions
* no separate thread needed to run MQTT - application only needs to call
mqtt_input and mqtt_live periodically

These changes were obtained by running a script created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:
1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
#define X Y)
3. Check if that name is also the name of a Kconfig option
3.a If it is, then do nothing
3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
(.c, .h, .ld)
Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.
Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c
