Piotr Mienkowski 001ef2d500 api: gpio: deprecate all gpio_port_ functions
The gpio_port_ functions provided by the gpio API do not provide
currently a mask parameter. As such they operate on a full port only.
In practice such functions are not useful. This commit deprecates them
to allow adding port functions with support for a mask parameter in the
future.

François Delawarde 4fac841869 debug: CTF Tracing with POSIX backend
This commit implements a CTF-backend for Zephyr's tracing API.
The CTF-backend itself is split in a middle-layer and a bottom-layer.
- Middle-layer decides the payload in event transactions,
- Bottom-layer implements the IO transport.

A simple POSIX bottom-layer is provided so far.

Tomasz Bursztyka 4b78a251d7 net/context: Make recv_cb providing the ip and protocol headers
If status is 0, both ip_hdr and proto_hdr will own a pointer to the
relevant IP and Protocol headers. In order to know which of ipv4/ipv6
and udp/tcp one will need to use respectively net_pkt_family(pkt) and
net_context_get_ip_proto(context).

Having access to those headers directly, many callbacks will not need
to parse the packet again no get the src/dst addresses or the src/dst
ports. This will be change after this commit.

Adding a cursor into net_pkt. This is used to read/write data in a much

Tomasz Bursztyka 8eb9ff72f6 net/pkt: Add new allocators
These struct net_pkt allocators will give the possibility to allocate at
once the net_pkt and the buffer associated with, taking care of the
header space and MTU relevantly.

This enables to use the variable length allocator from net_buf. However,
it is not yet the default and is set as experimental.

As it is provided in parallel to existing allocators, it has to keep a
slab per-direction and thus a pointer in net_pkt, as well as appdata,
appdatalen etc... Resulting in "bloating" net_pkt. This will be solved
when, finally, former allocators will be removed.

the client will start it's connection process over but now with

As part of the migration from net_app APIs to socket APIs, let's
stop referencing the net_pkt fragments throughout the LwM2M library.

Establish a msg_data flat buffer inside lwm2m_message and use that

NOTE: As a part of this change we remove the COAP_NET_PKT setting.
The COAP library reverts to COAP_SOCK behavior.

This doesn't mean we use sockets in LwM2M (yet), it only means we
use the socket-compatible COAP library which parses flat buffers
instead of net_pkt fragments.

The original SNTP client library was designed for the net-app API, for
which it makes sense to have a callback function, which is called
asynchronously when an answer is received.

For the socket based interface, the callback is called just before
sntp_request() returns. It gets the status and the epoch_time in
parameter, however the status is already returned by sntp_request(). It
therefore make sense to replace the callback function by a pointer to
epoch_time.

Andy Ross 7367b84f8e kernel/spinlock: Augment runtime validation
There was an existing validation layer in the spinlock implementation,
but it was only enabled when both SMP and CONFIG_DEBUG were enabled,
which meant that nothing was using it.  Replace it with a more
elaborate framework that ensures that every lock taken is not already
taken by the current CPU and is released on the same CPU by the same
thread.

This catches the much more common goof of locking a spinlock
recursively, which would "work" on uniprocessor setups but have the
side effect of releasing the lock prematurely at the end of the inner
lock.  We've done that in two spots already.

Note that this patch causes k_spinlock_t to have non-zero size on
builds with CONFIG_ASSERT, so expect a little data and code size
increase.  Worth it IMHO.

Daniel Glöckner 5ef825fdf6 net: pkt: fix race condition in packet reference counting
It has been observed that some network drivers, f.ex. the SAM E70 GMAC,
call net_pkt_unref from inside the interrupt that signals the successful
transmission of a packet. This conflicts with the net_pkt_unref call
made by ethernet_send after the packet has been given to the driver.

We fix this by using an atomic_t to hold the reference count as there
might be other, difficult to find cases of net_pkt_(un)ref being used
across threads and interrupts.

The name of the element has been changed from "ref" to "atomic_ref" to
cause a compile error when code still has not been converted to use the
atomic_* functions.

Robert Lubos 83b8abaf8a net: ip: Introduce mesh_local address flag
This commit introduces a concept of mesh-local IPv6 addresses. Such
addresses should only be used for mesh-local communication, therefore
should not be used to communicate with different subnets (i. e.
destinations outside the mesh).

As `addr_type` field already holds different kind of information
(whether address was created automatically/manually) it was not used in
this case.

Instead a mesh_local flag was added, so that we do not lose information
on how address was created. Address with such flag set will only be
selected as a source address automatically if the destination address
is within the same subnet it belongs to.

A recent change in how the fixup mechanism works caused several
regressions. See
https://github.com/zephyrproject-rtos/zephyr/pull/12680 for more

The core of the matter is that using defines to pass on include paths
causes interopability issues when integrating with external build
systems.

To resolve this we re-write the fixup mechanism to instead generate an
aggregated fixup file that is ready to be included at build time. Then
no paths are passed through defines and we resolve the regressions

This results in a simpler system because users can now read

Peter A. Bigot b4ece0ad44 kernel: timeout: detect inactive timeouts using dnode linked state
Whether a timeout is linked into the timeout queue can be determined
from the corresponding sys_dnode_t linked state.  This removes the need
to use a special flag value in dticks to determine that the timeout is
inactive.

Update _abort_timeout to return an error code, rather than the flag
value, when the timeout to be aborted was not active.

Remove the _INACTIVE flag value, and replace its external uses with an
internal API function that checks whether a timeout is inactive.

Peter A. Bigot d40b8ce1fb sys: dlist: Add sys_dnode_is_linked
The original implementation allows a list to be corrupted by list
operations on the removed node.  Existing code attempts to avoid this by
using external state to determine whether a node is in a list, but this
is fragile and fails when the state that holds the flag value is changed
after the node is removed, e.g. in preparation for re-using the node.

Follow Linux in invalidating the link pointers in a removed node.  Add
API so that detection of particpation in a list is available at the node
abstraction.

This solution relies on the following steady-state invariants:
* A node (as opposed to a list) will never be adjacent to itself in a
  list;
* The next and prev pointers of a node are always either both null or
  both non-null.

Andy Ross b69d0da82d arch/x86_64: New architecture added
This patch adds a x86_64 architecture and qemu_x86_64 board to Zephyr.
Only the basic architecture support needed to run 64 bit code is
added; no drivers are added, though a low-level console exists and is
wired to printk().

The support is built on top of a "X86 underkernel" layer, which can be
built in isolation as a unit test on a Linux host.

Limitations:

+ Right now the SDK lacks an x86_64 toolchain.  The build will fall
  back to a host toolchain if it finds no cross compiler defined,
  which is tested to work on gcc 8.2.1 right now.

+ No x87/SSE/AVX usage is allowed.  This is a stronger limitation than
  other architectures where the instructions work from one thread even
  if the context switch code doesn't support it.  We are passing
  -no-sse to prevent gcc from automatically generating SSE
  instructions for non-floating-point purposes, which has the side
  effect of changing the ABI.  Future work to handle the FPU registers
  will need to be combined with an "application" ABI distinct from the
  kernel one (or just to require USERSPACE).

+ Paging is enabled (it has to be in long mode), but is a 1:1 mapping
  of all memory.  No MMU/USERSPACE support yet.

+ We are building with -mno-red-zone for stack size reasons, but this
  is a valuable optimization.  Enabling it requires automatic stack
  switching, which requires a TSS, which means it has to happen after
  MMU support.

+ The OS runs in 64 bit mode, but for compatibility reasons is
  compiled to the 32 bit "X32" ABI.  So while the full 64 bit
  registers and instruction set are available, C pointers are 32 bits
  long and Zephyr is constrained to run in the bottom 4G of memory.

Zero length array is a GNU extension that works as an header for a
variable length object. The portable solution for this is using
flexible length array, but this can be used only in the end of a
struct declaration and this is violates MISRA-C rule 18.8.

The easiest way to rif of this is make the macro expand to nothing but
then we will have a trailing semicolon that is not allowed in C99. So
the macro was changed to automatically add the semicolon when needed.
This may break code identation in some editors but it is a fair price

Don't try to find "errors" in the values of dst_len and len params
passed to net_buf_linearize(). Instead, do what entails with the
common sense from the values passed in, specifically:

1. Never read more than dst_len (or it would lead to buffer
overflow).
2. It's absolutely ok to read than specified by "len" param, that's
why this function returns number of bytes read in the first place.

The motivation for this change is that it's not useful with its
current behavior. For example, a number of Ethernet drivers linearize
a packet to send, but each does it with its own duplicated adhoc
routine, because net_buf_linearize() would just return error for the
natural use of:

net_buf_linearize(buf, sizeof(buf), pkt->frags, 0, sizeof(buf));

Paul Sokolovsky 0925411356 tty: Remove buffer params from tty_init()
Let's have more orthogonal and cleaner API, where buffers are
configured by tty_set_rx_buf/tty_set_tx_buf, and only them. It
means that newly initialized tty starts in unbuffered mode, which
is somewhat a sidestep from a main usecase behind tty, which is
buffered operation, but again, having a cleaner API (and good
docs, explaining users how it should be and what they should do)
prevails.

Paul Sokolovsky a7df3a1e09 tty: Support unbuffered operation to extend usecase coverage
The whole "tty" concept is conceived around efficient
interrupt-driven operation. However, it's beneficial to add
non interupt-driven operation under the same API:

1. Wider usecase coverage in general.
2. Allows to use the same familiar API (based on POSIX concepts)
even for UART implementations without interrupt support.
3. Allows to switch operation dynamically based on the needs.
For example, if the system is in degraded mode and interrupt
handling cannot be trusted/disabled, allows to still output
diagnostic information to user. This was the original motivation
to provide such a mode, to support logging subsystem's "panic"
mode.

To implement this feature, tty_set_rx_buf() and tty_set_tx_buf()
functions are provided, allowing to reconfigure buffers used
dynamically. If configured buffer length is 0, the operation
switched to unbuffered.

to allow blocking logger thread if short-term arrival rate

The net-shell "net allocs" command should print network buffer
allocations even if network packet debugging is not enabled.
This is how it used to work earlier but the behaviour got lost
at some point. So user needs to set CONFIG_NET_DEBUG_NET_PKT_ALLOC
in order to see the buffer allocations. The option will be enabled
by default if network packet log level is set to DBG.
The reason for a separate option is that the network packet debug
logging prints just too much data and it is very difficult to

This patch reworks routines used to store and read the settings data.
Provide stream-style encoding and decoding to/from flash, so the the
API only requires a pointer to binary data, and the settings
implementation takes care of encoding/decoding to/from base64 and
writing/reading to/from flash on the fly. This would eliminate the
need of a separate base64 value buffer on the application-side, thereby
further contributing to the stack footprint reduction.

Above changes allows to remove:
  256-byte value length limitation.
  removing enum settings_type usage so all settings data are treated
  now as a byte array (i.e. what's previously SETTINGS_BYTES)

Introduced routine settings_val_read_cb for read and decode the
settings data from storage inside h_set handler implementations.
h_set settings handler now provide persistent value's context
used along with read routine instead of immediately value.

This commit reworks socket poll implementation to support multiple

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.

Ioannis Glaropoulos bf34cf9443 arch: arm: mpu: Updates in ARM MPU-related convenience macros
This commit does the following:
- it introduces additional convenience macros for representing
  MPU attributions for no-cacheability, in both ARMv7-M and
  ARMv8-M MPU architectures,
- it adds documentation in K_MEM_PARTITION_IS_WRITABLE/CACHEABLE
  macros in all macro definitions in the different MPU variants
- it moves the type definition of k_mem_partition_attr_t inside
  the architecture-specific MPU headers, so it can be defined
  per-architecture. It generalizes app_mem_domain.h, to be able
  to work with _any_ (struct) type of k_mem_partition_attr_t.
- it refactors the type of k_mem_partition_attr_t for ARMv8-M
  to comply with the MPU register API.
- for NXP MPU, the commit moves the macros for region access
  permissions' attributes inside nxp_mpu.h, to align with what
  we do for ARM MPU.

Ioannis Glaropoulos 39bf24a9bd kernel: expose k_mem_partition_attr_t outside User mode
This commit exposes k_mem_partition_attr_t outside User Mode, so
we can use struct k_mem_partition for defining memory partitions
outside the scope of user space (for example, to describe thread
stack guards or no-cacheable MPU regions). A requirement is that
the Zephyr build supports Memory protection. To signify this, a
new hidden, all-architecture Kconfig symbol is defined (MPU). In
the wake of exposing k_mem_partition_attr_t, the commit exposes
the MPU architecture-specific access permission attribute macros
outside the User space context (for all ARCHs), so they can be
used in a more generic way.

Marti Bolivar f4c3163d3b arch: riscv32: provide a general mechanism for saving SoC context
RISC-V permits myriad extensions to the ISA, any of which may imply
additional context that must be saved and restored on ISR entry and
exit. The current in-tree example is the Pulpino core, which has extra
registers used by ISA extensions for running loops that shouldn't get
clobbered by an ISR.

This is currently supported by including pulpino-specific definitions
in the generic architecture code. This works, but it's a bit inelegant
and is something of a layering violation. A more generic mechanism is
required to support other RISC-V SoCs with similar requirements
without cluttering the arch code too much.

Provide that by extending the semantics of the existing
CONFIG_RISCV_SOC_CONTEXT_SAVE option to allow other SoCs to allocate
space for saving and restoring their own state, promoting the
currently pulpino-specific __soc_save_context / __soc_restore_context
routines to a RISC-V arch API.

The cost of making this generic is two more instructions in each ISR
to pass the SoC specific context to these routines in a0 rather than
just assuming the stack points to the right place. This is minimal,
and should have been done anyway to keep with the ABI.

As a first (and currently only in-tree) customer, convert the Pulpino
SoC code to this new mechanism.

Tomasz Bursztyka dcc6eddfef net/ethernet: Centralize where and when header is filled in
Current code generating Ethernet header is scattered all over the place,
sometimes in functions that are supposed to check something (and not
filling the header). Not to say about innefficiency.

Src ll address does not need to be set in L2 as net_if.c handles that
already.

Broadcast dst ll address is the same in ipv4 or ipv6, thus factorizing.
In each case, multicast is filled in only at the relevant place.

This is the first step towards changing L2 sending logic, when L2 send
API function will be the only point of sending. The redirection from
driver to L2 again (which finally uses the right device API function to
send) it a temporary hack.

This simplifies the code but will also enable using statically
allocated net_buf and ethernet header payload buffer afterwards.

- it enforces alignment with the minimum MPU granularity at

- it enforces alignment with size if required by the MPU
  architecture.

Particularly for the Application Memory section, the commit
simplifies how the proper alignment is enforced, removing
the need of calculating the alignment with a post-linker
python script. It also removes the need for an additional
section for padding.

For the Application Shared Memory section(s), the commit
enforces minimum alignment besides the requirement for
alignment with size (for the respective MPUs) and fixes

There is not an easy way to relate an application's user_data to a

Each connection related callback function will have to loop for all
user_data and compare the saved pointer to the passed bt_conn
pointer. This is inefficient if there are many callback activations
during the connection.

This change makes the internal bt_conn mapping function accessible to
applications in conn.h. The function name is changed to
bt_conn_index() to clearly indicate that the function returns an
index of an array.
Add an ASSERT to catch illegal parameter.

Alexander Polleti 97b7a0adb0 logging: reorder designated initializers in __LOG macro
As C++ does not support designated initializers, including this file
in a c++ file caused a compilation error.
gcc allows them if they are ordered as the members appear in the
struct definition

I tested it with an application using mqtt and ethernet.

Krzysztof Chruscinski 96a610b736 shell: Fix log messages queueing for multiple instances
Shell log backend was using k_fifo to enqueue log messages.
It was using field in log message that was used for same
purpose in log_core before passing message to backends.
However, this method supported only single shell as
other shell was corruption the fifo because field was
reused.

Modified shell log backend to use k_msgq for pending
messages.

Krzysztof Chruscinski af973ca1e9 shell: enable UART backend without interrupts
Currently shell UART backend is interrupt driven if UART driver
is interrupt driven. That can be limitation if one instance
wants to use interrupts but shell UART should not.

Added option to shell uart to be able to control use of
interrupts. By default interrupts are enabled if driver
supports it.
