58e24f37fb arch: arm: introduce sync barriers in _arch_irq_unlock()
The ARM Cortex-M 321 application note is stressing that
when enabling interrupts by executing CPSIE i(f), or by MSR
instructions (on PRIMASK, FAULTMASK, or BASEPRI registers),
there is a need for synchronization barrier instructions,
if there is a requirement for the effect of enabling
interrupts to be recongnized immediately. _arch_irq_unlock()
is invoked in several places, therefore, we add the
barriers to make the interrupt enabling function
applicable to all usage scenarios.

c0183fdedd kernel/work_q: Fix locking across multiple queues
There was a detected user error in the code where racing insertions of
k_delayed_work items into different queues would be detected and
flagged as an error (honestly I don't see much value there -- Zephyr
doesn't as a general rule protect against errors like this, and
work_q's are inherently kernel things that don't require
userspace-style checking).

This got broken with spinlockification, where each work_q object got
its own lock, so the single lock wouldn't protect against the other
insert function any more.  As it happens, that was needless.  The core
synchronization on a work_q is in the internal k_queue object anyway
-- the lock in this file was only ever used for (very fast,
noncontending) delayed work insertion.  So go back to a global lock to
preserve the original behavior.

Fixes #14104

4508e94b4e net/pkt: Enable allocating from external slab and data pool on new API
This is meant for very particular use case as only logging uses that.
Where it makes entirely sense for it to send the logs through its own
slab/pool in order to not drain the core slabs/pools.

So enabling the new API to manage that. That has to be used with
net_context for the buffer pool. So one has to first allocate the
net_pkt from external slab, set the context and then (and only then)
allocate buffer. Basically, only net_context will uses that scheme
anyway.

4344e27c26 all: Update reserved function names
Update reserved function names starting with one underscore, replacing
them as follows:
   '_k_' with 'z_'
   '_K_' with 'Z_'
   '_handler_' with 'z_handl_'
   '_Cstart' with 'z_cstart'
   '_Swap' with 'z_swap'

This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.

Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.

Various generator scripts have also been updated as well as perf,
linker and usb files. These are
   drivers/serial/uart_handlers.c
   include/linker/kobject-text.ld

fe04adf99b lib/os: Conditionally eliminate alloca/VLA usage
MISRA rules (see #9892) forbid alloca() and family, even though those
features can be valuable performance and memory size optimizations
useful to Zephyr.

Introduce a MISRA_SANE kconfig, which when true enables a gcc error
condition whenever a variable length array is used.

When enabled, the mempool code will use a theoretical-maximum array
size on the stack instead of one tailored to the current pool
configuration.

The rbtree code will do similarly, but because the theoretical maximum
is quite a bit larger (236 bytes on 32 bit platforms) the array is
placed into struct rbtree instead so it can live in static data (and
also so I don't have to go and retune all the test stack sizes!).
Current code only uses at most two of these (one in the scheduler when
SCHED_SCALABLE is selected, and one for dynamic kernel objects when

This tunable is false by default, but is selected in a single test (a

992f29a1bc arch: make __ramfunc support transparent
Instead of having to enable ramfunc support manually, just make it
transparently available to users, keeping the MPU region disabled if not
used to not waste a MPU region. This however wastes 24 bytes of code
area when the MPU is disabled and 48 bytes when it is enabled, and
probably a dozen of CPU cycles during boot. I believe it is something
acceptable.

Note that when XIP is used, code is already in RAM, so the __ramfunc
keyword does nothing, but does not generate an error.

c45961daae power: Rework OS <-> Application interface
This commit simplifies OS <-> Application interface controlling power
management. In the previous approach application-based PM required
overriding sys_suspend() and sys_resume() functions. As these functions
actually implemented power state change, in such case application
basically had to provide own implementation of all PM-related stuff,
which was not portable and hard to maintain.

This commit changes this scheme: The sys_suspend() and sys_resume()
are now system functions while the application could either use
built-in power management policies or provide its own. All details
of power mode switching are now handled by the OS.

Also, this commit cleans up the Kconfig options related to system-level
power management grouping them under common CONFIG_SYS_PM_ prefix.

There are issues using lowercase min and max macros when compiling a C++
application with a third-party toolchain such as GNU ARM Embedded when
using some STL headers i.e. <chrono>.

This is because there are actual C++ functions called min and max
defined in some of the STL headers and these macros interfere with them.
By changing the macros to UPPERCASE, which is consistent with almost all
other pre-processor macros this naming conflict is avoided.

All files that use these macros have been updated.

46a02322ec shell: allow commands to suspend shell thread
It was possible to deadlock the shell when command
suspended shell's thread and next another thread wanted
to print something on the shell.

To avoid that shell releases mutex before entering command
handler. Due to this change some  adapations to shell
internal print functions have been applied.

This change addresses following usecase:
1. A command handler needs to call a (system) function which
communicate results via a callback, and this callback is expected
to print these results. The callback is called by the system from
another thread.
2. To achieve that, the handler needs to pass `struct shell *`
to callbacks, but also some other data specific to callback.
Thus, handles allocates some structure will those fields on
the stack.
3. The handler schedules this callback to be called.
4. As a reference to stack structure is passed to the callback,
the handler can't return immediately (or stack data will go out
of scope and will be overwritten).
5. So, the handler blocks waiting for callback to finish.

Previously, this scenario led to deadlock when the callback
trying or print to shell. With these changes, it just works,
as long as main handler and callback serialize there access
to the shell structure (i.e. when callback prints, the main
handler is blocked waiting for its completion).

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."

NOTE: Only One-Shot Mode (mode 1) is implemented in this patch.

function: zsock_received_cb() already get the ip header and the protocol
header, so it could grab the src addr/port from there. It would be way
more optimized to do so, since net_pkt_get_src_addr is costly as it
parses all over again the ip/protocol headers.

net_pkt_get_src_addr/net_pkt_get_dst_addr are removed.

603ea42764 kernel/queue: Spinlockify
Straightforward port.  Each struct k_queue object gets a spinlock to
control obvious data ownership.

Note that this port actually discovered a preexisting bug: the -ENOMEM
case in queue_insert() was failing to release the lock.  But because
the tests that hit that path didn't rely on other threads being
scheduled, they ran to successful completion even with interrupts
disabled.  The spinlock API detects that as a recursive lock when
asserts are enabled.

5aa7460e5c kernel/spinlock: Move validation out of header inlines
The validation checking recently added to spinlocks is useful, but
requires kernel-internals like _current and _current_cpu in a header

aa6e21c24c kernel: Split _Swap() API into irqlock and spinlock variants
We want a _Swap() variant that can atomically release/restore a
spinlock state in addition to the legacy irqlock.  The function as it
was is now named "_Swap_irqlock()", while _Swap() now refers to a
spinlock and takes two arguments.  The former will be going away once
existing users (not that many!  Swap() is an internal API, and the
long port away from legacy irqlocking is going to be happening mostly
in drivers) are ported to spinlocks.

Obviously on uniprocessor setups, these produce identical code.  But
SMP requires that the correct API be used to maintain the global lock.

46072632bd drivers: i2c: document problematic API and deprecated unused functions
The scatter/gather API for I2C assumes that all SoC implementations are
capable of supporting such operations, in particular performing a single
write (read) transaction that transfers from (to) multiple addresses in
memory.  This is not the case: for some driver implementations a write
of a device register address followed by a write of data to be stored in
that register will produce two bus transactions and be mis-interpreted
by the receiving device.

Extend the documentation of the I2C message flags to provide more
information about the breadth of implementation variation in their
interpretation.

i2c_burst_write cannot be deprecated because we have no replacement.
Clarify in the description that the behavior is not portable.

i2c_burst_read is not being deprecated because it is in use throughout
Zephyr.  The description is updated to reflect that it can be replaced
by i2c_write_read().

Deprecate unused convenience wrappers that depended on the burst APIs
but were never used in the tree.

7f42423c7c drivers: i2c: add convenience wrapper for common I2C transaction pair
It is commonly necessary to execute a pair of I2C transactions where the
first is a write transaction that identifies information held on the
device and a second is a read transaction that retrieves the identified
information.

Add API that performs this operation generically, without restricting
the type or size of the identification or content messages.  Follow the
argument order of the existing i2c_write and i2c_read methods.

This reduces the need to explicitly construct buffers for i2c_transfer,
or to use more restrictive API functions that perform a gather write
that is not reliable on all I2C bus driver implementations.

2d9bbdf5f3 x86: remove support for non-PAE page tables
PAE tables introduce the NX bit which is very desirable
from a security perspetive, back in 1995.

PAE tables are larger, but we are not targeting x86 memory
protection for RAM constrained devices.

Remove the old style 32-bit tables to make the x86 port
easier to maintain.

Renamed some verbosely named data structures, and fixed
incorrect number of entries for the page directory

d75495709d drivers: gpio: fix mis-use of slist API in callback processing
The iterator over registered callbacks failed to account for the
possibility that the callback would remove itself from the list.  If
this occurred any remaining callbacks would no longer be reachable from
the node.  Switch to the slist iterator that is safe for self-removal.

Note that the slist API remains unsafe for removal of subsequent nodes.
Even with the corrected code removal of the next callback registration
(cached in tmp) will result in it being called anyway, with the
remaining unremoved registrations not being called.  If the next
callback were removed and re-registered on a different device, the
callbacks would be invoked for the wrong device.

Resolve this by a documentation change describing the conditions under
which a change to callback registration from within a callback are
permitted.  Add a similar note regarding the effect of adding a
callback.  The current event invocation behavior for callbacks added
within an event is explicitly left unspecified, though in the current
slist implementation newly added callbacks will not be invoked until the
next event.

Closes #10186

b48478fef3 driver: gpio: remove documentation related to pin-based callback config
This reverts the documentation component of commit
eb6ea28649.

The original change broke the API contract: drivers that use GPIOs need
to be able to configure callbacks without being aware of whether a
particular implementation expects to use a mask or a pin ordinal.

Revert the API documentation to its original format, and mark that the
added field should be removed when issue #11565 is resolved.

ab46b1b3c5 kernel/sched: CPU mask affinity/pinning API
This adds a simple implementation of SMP CPU affinity to Zephyr.  The
API is simple and doesn't try to invent abstractions like "cpu sets".
Each thread has an enable/disable flag associated with each CPU in the
system, and the bits can be turned on and off (for threads that are
not currently runnable, of course) using an easy three-function API.

Because the implementation picked requires enumerating runnable
threads in priority order looking for one that match the current CPU,
this is not a good fit for the SCALABLE or MULTIQ scheduler backends,
so it currently can be enabled only for SCHED_DUMB (which is the
default anyway).  Fancier algorithms do exist, but even the best of
them scale as O(N_CPUS), so aren't quite constant time and often
require significant memory overhead to keep separate lists for
different cpus/sets.

The intended use here is for apps that want to "pin" threads to
specific CPUs for latency control, or conversely to prevent certain
threads from taking time on specific CPUs to leave them free for fast
response.

eda4c027da misc/dlist: Swap insertion API for a faster one
The sys_dlist_insert_*() functions had a behavior where a NULL
argument for the insertion position to sys_dlist_insert_after/before()
was interpreted as "the end of the list".  We never used that
convention (except in one spot internal to dlist.h which was not
itself used anywhere), and of course already have an API for appending
and prepending to a list.

In practice this was a performance disaster.  The NULL check is
virtually never provable statically by the compiler, so that test and
branch is present always.  And worse, the check and call to another
function was pushing this beyond the complexity limit for gcc to
inline a function (at -Os optimization anyway), forcing us to use
function calls for what should be a ~8 instruction sequence.  The
upshot is that dlist insertions were 2-3x slower than they needed to
be.

Deprecate these older APIs and introduce a new sys_dlist_insert() call
which can be much better optimized.

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.

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.

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.

361fdaac1a cmake: Fix the generation of fixup files
A recent change in how the fixup mechanism works caused several
regressions. See
https://github.com/zephyrproject-rtos/zephyr/pull/12680 for more
details about the regressions.

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
reported.

extract_dts_includes.py has been generating DT output and then
concatenating it with fixup header files to create
'generated_dts_board.h'.

In this patch we instead introduce a source file named
'generated_dts_board.h' and have it \#include the appropriate DT
output and fixup files.

This results in a simpler system because users can now read
'generated_dts_board.h' as C source code to see how fixup files and
generated DT output relate to each other. Whereas before they would
have to either read documentation or python code to gain the same
understanding.

Also, it reduces the scope and complexity of one of our most bloated
python scripts, extract_dts_includes.py.

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

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.

zsock_inet_pton() based on its implementation in include/net/socket.h.
This eventually leads to a call to _impl_zsock_inet_pton(), which is
not defined when offloading is enabled.

In this commit, we have chosen to directly call net_addr_pton() in
inet_pton() in the offload case to be efficient, and keep the
implementation as it is when offload is not enabled.

Fixes #12441

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.

d1ed336b9b kernel: Do not use zero-length array
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
to pay to have portability and compliance.

71e2e31a76 net: buf: linearize: Never return -ENOMEM, just do what user asked to
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));

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.

76f8b97871 subsys/settings: stream-style encoding and decoding to/from storage
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.

ee0b61fff8 net: sockets: Rework poll to support ioctl helper commands
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.

This patch splits the text section into 2 parts. The first section

This is needed to force the required functions and data variables

This is due to the behavior of the linker. The linker will only link
once and hence this text section had to be split to make room
for the generated linker script.

Added a new Kconfig CODE_DATA_RELOCATION which when enabled will

- 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.

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.

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.

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.

62c5894bc1 arch: arm: properly enforce MPU-aware linker section alignment
This commit standardizes and simplifies the way we enforce
linker section alignment, to comply with minimum alignment
requirement for MPU, if we build Zephyr with MPU support:
- it enforces alignment with the minimum MPU granularity at
  the beginning and end of linker sections that require to
  be protected by MPU,
- 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
a bug where the app_data_align was erronously used in the
scipts for auto-generating the linker scripts.

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

application's user_data array upon connection establishment.
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.

5e6f220713 kernel: Fix type of Z_EXC_HANDLE
The type of Z_EXC_HANDLE was incorrectly declared, this was causing
the compiler to make incorrect inferences about what could be in
exc_handle and caused a bug in fault.c.

To get more specific ...

An exception handler consists of three void pointers, or function
pointers. The function pointers point to functions. An example of one
such function is 'z_arch_user_string_nlen_fault_start' From
userspace.S.

The correct way of initalizing a function pointer from a function
declared in another source file looks like this:

void external_defined_function(void);

{
   void * internal_initialized_function_ptr = external_defined_function;
}

But EXC_HANDLER is not doing this. Instead it does this:

extern void (*external_defined_function)(void);

{
  void * internal_initialized_function_ptr = &external_defined_function;
}

The declaration here is wrong. It declares that externally, there is
stored a function pointer somewhere. Which is not true. There does not
exist a function pointer anywhere. But this doesn't matter, because we
don't actually de-reference the function pointer to find the address
of the function, but instead we take the address of the function
pointer.

Taking the address of the function pointer to find the address of a
function is wrong, one should de-reference function pointers to find
function addresses. Luckily, these two bugs have been cancelling each
other out, until recently.

This patch corrects the type used.

20202902f2 dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig
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

f75d11adb2 logging: Handle nios2 global pointer register issue
Nios2 is trying to use global pointer register to access variables
smaller than 8 bytes. GPR range is limited to 64 bytes and apparently
does not handle well variables placed in custom sections.

Current workaround is to increase logger structures (const and dynamic)
size (+8 bytes for dynamic, +4 bytes for constant). Then GPR is not
used and application can be linked. The downside is increase of memory
usage:
- ROM: <num_of_log_modules>*4 bytes
- RAM: <num_of_log_modules>*8 bytes (if runtime filtering is enabled)

7bac15f2ff x86: add dynamic interrupt support
If dynamic interrupts are enabled, a set of trampoline stubs
are generated which transfer control to a common dynamic
interrupt handler function, which then looks up the proper
handler and parameter and then executes the interrupt.

Based on the prior x86 dynamic interrupt implementation which
was removed from the kernel some time ago, and adapted to
changes in the common interrupt handling code, build system,
and IDT generation tools.

An alternative approach could be to read the currently executing
vector out of the APIC, but this is a much slower operation.

This commit contributes a patch to the Arm Cortex-M linker
script, which guarantees that the linker sections for shared
memory and the application memory will have sufficient padding
in between, so that the latter will start from an address that
is 32-byte aligned. This is required for ensuring that the MPU
regions defined using the start and end addresses of the two
sections will not overlap. The patch targets ARMv8-M MPU with
no requirement for power-of-two alignment and size.

and the placement is based on linker heuristic which is
arbitrary.

987c0e5fc1 kernel: New timeout implementation
Now that the API has been fixed up, replace the existing timeout queue
with a much smaller version.  The basic algorithm is unchanged:
timeouts are stored in a sorted dlist with each node nolding a delta
time from the previous node in the list; the announce call just walks
this list pulling off the heads as needed.  Advantages:

* Properly spinlocked and SMP-aware.  The earlier timer implementation
  relied on only CPU 0 doing timeout work, and on an irq_lock() being
  taken before entry (something that was violated in a few spots).
  Now any CPU can wake up for an event (or all of them) and everything
  works correctly.

* The *_thread_timeout() API is now expressible as a clean wrapping
  (just one liners) around the lower-level interface based on function
  pointer callbacks.  As a result the timeout objects no longer need
  to store backpointers to the thread and wait_q and have shrunk by
  33%.

* MUCH smaller, to the tune of hundreds of lines of code removed.

* Future proof, in that all operations on the queue are now fronted by
  just two entry points (_add_timeout() and z_clock_announce()) which
  can easily be augmented with fancier data structures.

96013b0375 system_timer.h: Change "now" uptime API to be simpler for drivers
The current z_clock_uptime() call (recently renamed from
_get_elapsed_program_time) requires the driver to track a full 64 bit
uptime value in ticks, which is entirely separate from the one the
kernel is already keeping.

Don't do that.  Just ask the drivers to track uptime since the last
call to z_clock_announce(), since that is going to map better to
built-in hardware capability.

Obviously existing drivers already have this feature, so they're
actually getting slightly larger in order to implement the new API in
terms of the old one.  But future drivers will thank us.

is waiting, but it only uses that value in one spot (and there only as
a boolean flag indicating "this thread is waiting on a wait_q).

As it happens threads can already store their own backpointers to a
wait_q (needed for the SCALABLE scheduler backend), so we should use
that instead.

This patch doesn't actually perform that unification yet.  It
reorgnizes things such that the pended_on field is always set at the
point of timeout interaction, and adds a bunch of asserts to make 100%
sure the logic is correct.  The next patch will modify the API.

0e4532a3d4 sys_clock.h: Remove variance of _TICK_ALIGN with TICKLESS_KERNEL
Not sure why this was here.  The point to this API (which is poorly
explained) is to "round up" requested timeout values to an integer
number of ticks in the future, so the timeouts don't expire too soon.

There's no change of that requirement in tickless mode.  While the
"tick" unit will typicaly be a much smaller time (and thus much less
likely to have this kind of aliasing bug), we STILL don't want early
expiration.

And as with everything else in tickless, changing this breaks no
tests.  So remove it as a needless TICKLESS dependency.

722a888ef7 timer: Clean up hairy tickless APIs
The tickless driver had a bunch of "hairy" APIs which forced the timer
drivers to do needless low-level accounting for the benefit of the
kernel, all of which then proceeded to implement them via cut and
paste.  Specifically the "program_time" calls forced the driver to
expose to the kernel exactly when the next interrupt was due and how
much time had elapsed, in a parallel API to the existing "what time is
it" and "announce a tick" interrupts that carry the same information.

Remove these from the kernel, replacing them with synthesized logic
written in terms of the simpler APIs.

In some cases there will be a performance impact due to the use of the
64 bit uptime call, but that will go away soon.

ab488277bc drivers/timer: Unify timeout setting APIs
The existing API had two almost identical functions: _set_time() and
_timer_idle_enter().  Both simply instruct the timer driver to set the
next timer interrupt expiration appropriately so that the call to
z_clock_announce() will be made at the requested number of ticks.  On
most/all hardware, these should be implementable identically.

Unfortunately because they are specified differently, existing drivers
have implemented them in parallel.

Specify a new, unified, z_clock_set_timeout().  Document it clearly
for implementors.  And provide a shim layer for legacy drivers that
will continue to use the old functions.

Note that this patch fixes an existing bug found by inspection: the
old call to _set_time() out of z_clock_announce() failed to test for
the "wait forever" case in the situation where clock_always_on is
true, meaning that a system that reached this point and then never set
another timeout would freeze its uptime clock incorrectly.

fa99ad66d0 sys_clock: Fix up tick announce API
There were three separate "announce ticks" entry points exposed for
use by drivers.  Unify them to just a single z_clock_announce()
function, making the "final" tick announcement the business of the
driver only, not the kernel.

Note the oddness with "_sys_idle_elapsed_ticks": this was a global
variable exposed by the kernel.  But it was never actually used by the
kernel.  It was updated and inspected only within the timer drivers,
and only so that it could be passed back to the kernel as the default
(actually hidden) argument to the announce function.  Break this false
dependency by putting this variable into each timer driver
individually.

317178b88f sys_clock: Fix unsafe tick count usage
The system tick count is a 64 bit quantity that gets updated from
interrupt context, meaning that it's dangerously non-atomic and has to
be locked.  The core kernel clock code did this right.

But the value was also exposed to the rest of the universe as a global
variable, and virtually nothing else was doing this correctly.  Even
in the timer ISRs themselves, the interrupts may be themselves
preempted (most of our architectures support nested interrupts) by
code that wants to set timeouts and inspect system uptime.

Define a z_tick_{get,set}() API, eliminate the old variable, and make
sure everyone uses the right mechanism.

b8ffd9acd6 sys_clock: Make clock_always_on true by default
This flag is an indication to the timer driver that the OS doesn't
care about rollover conditions of the tick count while idling, so the
system doesn't need to wake up once per counter flip[1].  Obviously in
that circumstance values returned from k_uptime_get_32() are going to
be wrong, so the implementation had an assert to check for misuse.

But no one understood that from the docs, so the only place these APIs
were used in practice were as "guards" around code that needed to call
k_uptime_get_32(), even though that's 100% wrong per docs!

Clarify the docs.  Remove the incorrect guards.  Change the flag to
initialize to true so that uptime isn't broken-by-default in tickless
mode.  Also move the implemenations of the functions out of the
header, as there's no good reason for these to need to be inlined.

[1] Which can be significant.  A 100MHz ARM using the 24 bit SysTick
    counter rolls over at about 6 Hz, and if it had to come out of
    idle at that rate it would be a significant power issue that would
    swamp the gains from tickless.  Obviously systems with slow
    counters like nRF or 64 bit ones like RISC-V or x86's TSC aren't
    as affected.

Properly, these should be an API defined by the timer driver (who

9960bd9545 portability: Ensure no C99-illegal semicolons exists in structs
Macro _OBJECT_TRACING_NEXT_PTR expands to a member or to nothing.
Macro _OBJECT_TRACING_NEXT_PTR is used in a number of places, like:

        struct k_stack {
                .. omitted ..
                _OBJECT_TRACING_NEXT_PTR(k_stack);
                u8_t flags;
        };

When the macro expands to nothing, a lonesome semi would remain. This is
illegal in C99, but permitted in GCC with GNU extensions.

Rather than expand to empty, we now expand to a zero-length array.
This means we can retain the trailing semis across structs wherein the
macro is used.

Note that zero-length array (foo[0]) != flexible array member (foo[]):
 * zero-length array: Is GNU+Clang extension. Anywhere in struct.
 * flexible array member: Is C99. Only in end of struct.

Thus we have really only traded-off one portability issue for
another, more acceptable, one at least.

eb6ea28649 gpio: enable callback to specify pin in addition to pin_mask
There are GPIO controllers that can control more than 32 pins.
The pin_mask is no longer adequate in this case. This wraps
the pin_mask in a union together with a field named 'pin'.
The driver is responsible for choosing whether to use
pin_mask or pin.

878a0f050e ld: Put 'sizeof(struct device)' in the generated offsets header
Rename _DEVICE_STRUCT_SIZE to _DEVICE_STRUCT_SIZEOF. This causes it to
be picked by the script 'gen_offset_header.py' and inserted into the
header file 'include/generated/offsets.h'.

Renaming from x_SIZE to x_SIZEOF will align it's name with the other
symbols that denote a sctruct's size, like K_THREAD_SIZEOF.

Furthermore, it will allow the symbol to be accessed through a header
file define, instead of only as an extern symbol. This is more
flexible, and more aligned with the other symbols in offsets.

Finally, if we are able to move all of offsets.c symbols into the
offsets.h header file we be able to remove offsets.o from the link and
thereby simplify the linking process.

c7d2734455 kernel: Improve precision of ticks and ms conversions
The following 2 improvements are contained in this patch:

- When converting from ms to ticks, instead of using hardware cycles
  per tick, use hardware cycles per second. This ensures that the
  multiplication is done before the division, increasing precision.
- When converting from ticks to ms, instead of using cycles per tick
  and cycles per sec, use ticks per sec. This too increases the
  precision.

The concept is to make the dividend as large as possible compared to the
divisor in order to lose as little precision as possible.

45c0b20470 kernel: k_poll: Introduce separate status for cancelled events
Previously (as introduced in 48fadfe62), if k_poll() waited on a
queue (or subclass like fifo), and wait was cancelled on queue's
side using k_queue_cancel_wait(), k_poll returned -EINTR. But it
did not set event->state field (to anything else but
K_POLL_STATE_NOT_READY), so in case of waiting on multiple queues,
it was not possible to differentiate which of them was cancelled.

This in particular broke detection of network socket EOF conditions
in POSIX poll() implementation.

This situation is now resolved with introduction of explicit
K_POLL_STATE_CANCELLED state, which is now set for cancelled queue
(-EINTR return remains the same).

This change also elaborates docstring for the functions mentioned, to
document this behavior.

f1891e9473 drivers: adc: Introduce reworked API
This commit replaces the API for ADC drivers with a reworked one.
As requested in the issue #3980, the adc_enable/adc_disable functions
are removed. Additionaly, some new features are introduced, like:
- asynchronous calls
- configuration of channels
- multi-channel sampling

Common parts of code that are supposed to appear in each implementation
of the driver (like locking, synchronization, triggering of consecutive
samplings) are provided in the "adc_context.h" file to keep consistency
with the SPI driver. Syscalls are no longer present in the API because
the functions starting read requests cannot use them, since they can be
provided with a callback that is executed in the ISR context, and there
is no point in supporting syscalls only for the channels configuration.

"adc_api" test is updated and extended with additional test cases,
with intention to show how the API is supposed to be used.
"adc_simple" test is removed as it does not seem to add much value.

17e9d623b4 kernel: Enable interrupts for MULTITHREADING=n on supported arch's
Some applications have a use case for a tiny MULTITHREADING=n build
(which lacks most of the kernel) but still want special-purpose
drivers in that mode that might need to handle interupts.  This
creates a chicken and egg problem, as arch code (for obvious reasons)
runs _Cstart() with interrupts disabled, and enables them only on
switching into a newly created thread context.  Zephyr does not have a
"turn interrupts on now, please" API at the architecture level.

So this creates one as an arch-specific wrapper around
_arch_irq_unlock().  It's implemented as an optional macro the arch
can define to enable this behavior, falling back to the previous
scheme (and printing a helpful message) if it doesn't find it defined.
Only ARM and x86 are enabled in this patch.

71ca65306c mempool: Fix bit pointer state for N_MAX > 31
When a mempool is created with a large number of maximum-size blocks,
the logic for initializing max_inline_level (i.e. when to union the
bitmask with the pointer and when to use the pointer directly) was
wrong.  The default state was "zero", which implies that level 0
should be inlined, but that's wrong with >32 base blocks.
Additionally, the type was unsigned, making the "level zero is a
pointer" situation impossible to represent.

7d2e59813f subsys: fs/nvs: Rewrite for improved robustness
On flash NVS was stored one entry after another including the metadata
of each entry. This has the disadvantage that when an incomplete write
is performed (e.g. due to power failure) the complete sector had to be
rewritten to get a completely functional system.

The present rewrite changed the storage in flash of the data. For each
sector the data is now written as follows: the data itself at the
beginning of the sector (one after the other), the metadata (id, length,
data offset in the sector, and a crc of the metadata) is written from
the end of the sector. The metadata is of fixed size (8 byte) and for
a sector that is completely occupied a metadata entry of all zeros is
used.

Writing data to flash always is done by:
1. Writing the data,
2. Writing the metadata.

If an incomplete write is done NVS will ignore this incomplete write.

At the same time the following improvements were done:
1. NVS now support 65536 sectors of each 65536 byte.
2. The sector size no longer requires to be a power of 2 (but it
still needs to be a multiple of the flash erase page size).
3. NVS now also keeps track of the free space available.

b9dead0a42 subsys: fs/nvs: Improved nvs for larger blocksizes
The nvs module has some disadvantages for larger block size. The data
header and slot are taking up to much space. A rewrite is proposed that
reduces the used storage space for systems with write block size > 4.

The data storage in flash is now one unit consisting of: data_length,
data_id, data and data_length again in a multiple of the write block
size. The data_length at the end is used to validate the correctness of
the flash write and also allows to travel backwards in the filesystem.

As a comparison, on a system with block size 8 byte, a 32 bit values
now fits 1 block including the metadata (length and id). This used to
be 3 blocks.

The data_length will occupy 1 byte if the data length is less than 128
byte, it will occupy 2 byte if the data length is 128 byte or more. The
data length is limited to 16383 byte.

Each write to flash is verified by a read back of the data.

The read performance is improved because reading is done backwards so
the latest items are found first.

When the filesystem is locked it can be unlocked by calling
reinit(), this will clear flash and setup everything for storage.

598276262c net: l2: Add support for Link Layer Discovery Protocol (LLDP)
The LLDP protocol defines 2 separate agents, the Transmitters and
the Receivers. For the context of Zephyr, we are only interested in
the Tx agent, thus we drop any LLDP frames received by Zephyr.

LLDP frames are basically composed by an ethernet header followed by
the LLDP Protocol Data Unit (LLDPDU). The LLDPDU is composed by several
TLVs, some of them being mandatory and some optional.

Our approach here is having TLVs fully configured from Kconfig, thus
having the entire LLDPDU constructed on build time.

The commit adds NET_ETH_PTYPE_LLDP definition and related handling.

If CONFIG_NET_LLDP is enabled then ethernet_context has a pointer to
the struct net_lldpdu that belongs to that ethernet interface. Also
when CONFIG_NET_LLDP is enabled, the LLDP state machine will start to
send packets when network interface is coming up.

Currently the LLDP state machine is just a k_delayed_work() sending the
LLDPDU at a given period (defined by CONFIG_NET_LLDP_TX_INTERVAL).

db577f00b1 net: buf: add linearize, append_bytes and skip APIs to net_buf
This change moves the logic for linearize and append_bytes from
the net_pkt sources into the net_buf sources where it can be
made available to layers which to not depend on net_pkt.  It also,
adds a new net_buf_skip() function which can be used to iterated
through a list of net_buf (freeing the buffers as it goes).

For the append_bytes function to be generic in nature, a net_buf
allocator callback was created.  Callers of append_bytes pass in
the callback which determines where the resulting net_buf is
allocated from.

Also, the dst buffer in linearize is now cleared prior to copy
(this was an addition from the code moved from net_pkt).

In order to preserve existing callers, the original functions are
left in the net_pkt layer, but now merely act as wrappers.

57286afdd6 drivers: uart: Allow to pass arbitrary user data to irq callback
Zephyr UART drivers offer very low-level functionality. Oftentimes,
it would be useful to provide higher-level wrappers around UART
device which would offer additional functionality. However, UART
driver irq callback routine receives just a pointer to (low-level)
UART device, and it's not possible to get to a wrapper structure
(without introducing expensive external mapping structures). This
is an indirect reason why the current UARt wrappers - uart_pipe,
console - are instantiated statically just for one underlying UART
device and cannot be reused for multiple devices.

Solve this by allowing to pass an arbitrary user data to irq
callback, set by new uart_irq_callback_user_data_set() function.
Existing uart_irq_callback_set() keeps setting a callback which
will receive pointer to the device.

While public API maintains compatibility, drivers themselves need
to be updated to support arbitrary user data storage/passing (as
legacy uart_irq_callback_set() functionality is now implemented in
terms of it).

df8d4e96ef logging: fix multi-file module support
The documentation says a module can be split up over multiple files,
but there's no good way to do that. In the file with the
LOG_MODULE_REGISTER() call, the definitions of the module's state
variables serve as declarations that LOG_DBG(), etc. can use. But in
other files making up the module, no such declarations are available,
and the macro expansion bombs out spectacularly and confusingly.

Fix this by adding a LOG_MODULE_DECLARE() macro which other files in
the module can use to declare the internal state used by the log
module, so that LOG_DBG() etc. work properly.

573f32b6d2 userspace: compartmentalized app memory organization
Summary: revised attempt at addressing issue 6290.  The
following provides an alternative to using
CONFIG_APPLICATION_MEMORY by compartmentalizing data into
Memory Domains.  Dependent on MPU limitations, supports
compartmentalized Memory Domains for 1...N logical
applications.  This is considered an initial attempt at
designing flexible compartmentalized Memory Domains for
multiple logical applications and, with the provided python
script and edited CMakeLists.txt, provides support for power
of 2 aligned MPU architectures.

Overview: The current patch uses qualifiers to group data into
subsections.  The qualifier usage allows for dynamic subsection
creation and affords the developer a large amount of flexibility
in the grouping, naming, and size of the resulting partitions and
domains that are built on these subsections. By additional macro
calls, functions are created that help calculate the size,
address, and permissions for the subsections and enable the
developer to control application data in specified partitions and
memory domains.

Background: Initial attempts focused on creating a single
section in the linker script that then contained internally
grouped variables/data to allow MPU/MMU alignment and protection.
This did not provide additional functionality beyond
CONFIG_APPLICATION_MEMORY as we were unable to reliably group
data or determine their grouping via exported linker symbols.
Thus, the resulting decision was made to dynamically create
subsections using the current qualifier method. An attempt to
group the data by object file was tested, but found that this
broke applications such as ztest where two object files are
created: ztest and main.  This also creates an issue of grouping
the two object files together in the same memory domain while
also allowing for compartmenting other data among threads.

Because it is not possible to know a) the name of the partition
and thus the symbol in the linker, b) the size of all the data
in the subsection, nor c) the overall number of partitions
created by the developer, it was not feasible to align the
subsections at compile time without using dynamically generated
linker script for MPU architectures requiring power of 2
alignment.

In order to provide support for MPU architectures that require a
power of 2 alignment, a python script is run at build prior to
when linker_priv_stacks.cmd is generated.  This script scans the
built object files for all possible partitions and the names given
to them. It then generates a linker file (app_smem.ld) that is
included in the main linker.ld file.  This app_smem.ld allows the
compiler and linker to then create each subsection and align to
the next power of 2.

Usage:
 - Requires: app_memory/app_memdomain.h .
 - _app_dmem(id) marks a variable to be placed into a data
section for memory partition id.
 - _app_bmem(id) marks a variable to be placed into a bss
section for memory partition id.
 - These are seen in the linker.map as "data_smem_id" and
"data_smem_idb".
 - To create a k_mem_partition, call the macro
app_mem_partition(part0) where "part0" is the name then used to
refer to that partition. This macro only creates a function and
necessary data structures for the later "initialization".
 - To create a memory domain for the partition, the macro
app_mem_domain(dom0) is called where "dom0" is the name then
used for the memory domain.
 - To initialize the partition (effectively adding the partition
to a linked list), init_part_part0() is called. This is followed
by init_app_memory(), which walks all partitions in the linked
list and calculates the sizes for each partition.
 - Once the partition is initialized, the domain can be
initialized with init_domain_dom0(part0) which initializes the
domain with partition part0.
 - After the domain has been initialized, the current thread
can be added using add_thread_dom0(k_current_get()).
 - The code used in ztests ans kernel/init has been added under
a conditional #ifdef to isolate the code from other tests.
The userspace test CMakeLists.txt file has commands to insert
the CONFIG_APP_SHARED_MEM definition into the required build
targets.
  Example:
        /* create partition at top of file outside functions */
        app_mem_partition(part0);
        /* create domain */
        app_mem_domain(dom0);
        _app_dmem(dom0) int var1;
        _app_bmem(dom0) static volatile int var2;

        int main()
        {
                init_part_part0();
                init_app_memory();
                init_domain_dom0(part0);
                add_thread_dom0(k_current_get());
                ...
        }

 - If multiple partitions are being created, a variadic
preprocessor macro can be used as provided in
app_macro_support.h:

        FOR_EACH(app_mem_partition, part0, part1, part2);

or, for multiple domains, similarly:

        FOR_EACH(app_mem_domain, dom0, dom1);

Similarly, the init_part_* can also be used in the macro:

        FOR_EACH(init_part, part0, part1, part2);

Testing:
 - This has been successfully tested on qemu_x86 and the
ARM frdm_k64f board.  It compiles and builds power of 2
aligned subsections for the linker script on the 96b_carbon
boards.  These power of 2 alignments have been checked by
hand and are viewable in the zephyr.map file that is
produced during build. However, due to a shortage of
available MPU regions on the 96b_carbon board, we are unable
to test this.
 - When run on the 96b_carbon board, the test suite will
enter execution, but each individaul test will fail due to
an MPU FAULT.  This is expected as the required number of
MPU regions exceeds the number allowed due to the static
allocation. As the MPU driver does not detect this issue,
the fault occurs because the data being accessed has been
placed outside the active MPU region.
 - This now compiles successfully for the ARC boards
em_starterkit_em7d and em_starterkit_em7d_v22. However,
as we lack ARC hardware to run this build on, we are unable
to test this build.

Current known issues:
1) While the script and edited CMakeLists.txt creates the
ability to align to the next power of 2, this does not
address the shortage of available MPU regions on certain
devices (e.g. 96b_carbon).  In testing the APB and PPB
regions were commented out.
2) checkpatch.pl lists several issues regarding the
following:
a) Complex macros. The FOR_EACH macros as defined in
app_macro_support.h are listed as complex macros needing
parentheses.  Adding parentheses breaks their
functionality, and we have otherwise been unable to
resolve the reported error.
b) __aligned() preferred. The _app_dmem_pad() and
_app_bmem_pad() macros give warnings that __aligned()
is preferred. Prior iterations had this implementation,
which resulted in errors due to "complex macros".
c) Trailing semicolon. The macro init_part(name) has
a trailing semicolon as the semicolon is needed for the
inlined macro call that is generated when this macro
expands.

Update: updated to alternative CONFIG_APPLCATION_MEMORY.
Added config option CONFIG_APP_SHARED_MEM to enable a new section
app_smem to contain the shared memory component.  This commit
seperates the Kconfig definition from the definition used for the
conditional code.  The change is in response to changes in the
way the build system treats definitions.  The python script used
to generate a linker script for app_smem was also midified to
simplify the alignment directives.  A default linker script
app_smem.ld was added to remove the conditional includes dependency
on CONFIG_APP_SHARED_MEM.  By addining the default linker script
the prebuild stages link properly prior to the python script running

bc94cc1832 libc: minimal: add console system calls
The stdout console implementations for minimal libc call directly into
the various console drivers (depending on what specifc hooks are
registered) causing faults when invoked from user mode. This happens,
for example, when using printf() which eventually ends up calling
fputc().

The proper solution is to ensure privileges have been elevated before
the _stdout_hook is called. This was already done for printk().

puts() and fputs() have now been re-defined in terms of the
fputc() and fwrite() functions, which are now system calls.

7f4d006959 kernel: fix errno access for user mode
The errno "variable" is required to be thread-specific.
It gets defined to a macro which dereferences a pointer
returned by a kernel function.

In user mode, we cannot simply read/write the thread struct.
We do not have thread-local storage mechanism, so for now
use the lowest address of the thread stack to store this
value, since this is guaranteed to be read/writable by
a user thread.

The downside of this approach is potential stack corruption
if the stack pointer goes down this far but does not exceed
the location, since a fault won't be generated in this case.

2ca3b1e3c4 net: if: Fix TX timestamp callbacks invocation
The problem is that net_if_call_timestamp_cb only checked if the
callback was registered for the PORT which invoked the whole action.

There is a possibility, that the callback will be registered, and packet
A will be passed to eth driver. Before the driver is finished with
packet A, network layer will start handling another packet (B) - so it
will unregister the callback for packet A and register it for B. After
that the network driver will finish processing packet A and invoke the
timestamp callback. The mechanism would then only check if a callback is
registered for the port of the driver and invoke the callback for the

df41ed885a arch: arm: mpu: replace literals with CMSIS bitsets
This commit refactors internal functions in arm_mpu.c to use
bitsets and functions taken directly from ARM CMSIS instead of
hardcoded arithmetic literals. In several internal functions
some part of the implementation is abstracted further in inline
functions or convenience macros, to facilitate extending the
arm_mpu.c for ARMv8-M. In addition, the commit adds minor
improvements in internal function documentation.

d55a6aa32d i2c: Add new I2C Slave syscalls
This patchs adds new I2C Syscalls for :
- I2C controllers slave support
- I2C Slave drivers support

I2C Controllers slave support adds 2 new ops to :
- register new slave driver
- unregister slave driver

Slave funcs consists on all the I2C phases :
- read or write request once address matches
- read or write done once the byte has been received/sent
- stop when the trasmit stops

I2C Slave drivers syscall are also added to make new
"I2C Slave" drivers to :
- register them to their I2C controller
- unregister them to their I2C controller

The kernel incorrectly assumed, that system timer frequency is always

As result on some SoCs, time calculations was not correct, producing
strange effects (invalid sleep times, incorrect k_uptime_get() etc.).

This commit enables accurate, but costly (using 64-bit math) tick <-> ms

* We are now *much* better at not reserving unnecessary
system MPU regions based on configuration. The #defines
for intent are now an enumerated type. As a bonus, the
implementation of _get_region_index_by_type() is much
simpler. Previously we were wasting regions for stack guard
and application memory if they were not configured.

* NXP MPU doesn't reserve the last region if HW stack
protection isn't enabled.

* Certain parts of the MPU code are now properly ifdef'd
based on configuration.

* THREAD_STACK_REGION and THREAD_STACK_USER_REGION was a
confusing construction and has now been replaced with
just THREAD_STACK_REGION, which represents the MPU region
for a user mode thread stack. Supervisor mode stacks
do not require an MPU region.

* The bounds of CONFIG_APPLICATION_MEMORY never changes
and we just do it once during initialization instead of
every context switch.

* Assertions have been added to catch out-of-bounds cases.

55a7e46b66 kernel/poll: Remove POLLING thread state bit
The _THREAD_POLLING bit in thread_state was never actually a
legitimate thread "state".  It is a clever synchronization trick
introduced to allow the thread to release the irq_lock while looping
over the input event array without dropping events.

Instead, make that flag a word in the "poller" struct that lives on
the stack of the thread calling k_poll.  The disadvantage is the 4
bytes of thread space needed.  Advantages:

+ Cleaner API, it's now internal to poll instead of being globally
  visible.

+ The thread_state bit space is just one byte, and was almost full
  already.

+ Smaller code to write/test a full word and not a bitfield

+ Words are atomic, so no need for one of irq lock/unlock pairs.

2dd91eca0e kernel: move thread monitor init to common code

the entry function with arguments for any given thread.

This is problematic:

- Some arches do not have a initial stack layout suitable for

- Some arches never enabled this at all (riscv32, nios2)
- Some arches did not enable this properly
- Dropping to user mode would erase or provide incorrect

if GCC provides it as an extension, that's unrelated to a particular

This actually broke on the ESP-32 IDF toolchain, where (when using

about a loss of information (27 bits to 16 bits in the case I found).

+ The old static multi-queue implementation is gone and has been
  replaced with a build-time choice of either a "dumb" list
  implementation (faster and significantly smaller for apps with only
  a few threads) or a balanced tree queue which scales well to
  arbitrary numbers of threads and priority levels.  This is
  controlled via the CONFIG_SCHED_DUMB kconfig variable.

  threads were waiting on a single object.  This can be selected via

on them with the dlist APIs.  Refactor _wait_q_t into a proper opaque
struct (not a typedef for sys_dlist_t) and write a simple wrapper API
for the existing usages.  Now replacement of wait_q with a different
data structure is much cleaner.

Note that there were some SYS_DLIST_FOR_EACH_SAFE loops in mailbox.c
that got replaced by the normal/non-safe macro.  While these loops do
mutate the list in the code body, they always do an early return in
those circumstances instead of returning into the macro'd for() loop,
so the _SAFE usage was needless.

3772f77119 k_poll: expose to user mode
k_poll is now accessible from user mode. A memory allocation takes place
from the caller's resource pool to copy the provided poll_events
array; this can be large enough to make allocating it on the stack
not preferable.

k_poll_signal are now proper kernel objects. Two APIs have been added,
one to reset the signaled state and one to check the current signaled
state and result value.

39d63d316b clock_control: Add support for getting LPO frequency in mcux sim driver
The mcux sim clock control driver was originally designed to pass
through the clock subsystem value from dts to the mcux CLOCK_GetFreq()
function. This assumed that the values in
include/dt-bindings/clock/kinetis_sim.h matched the enumeration in
fsl_clock.h, which is true for the coresys, platform, and bus clocks.
However, the low-power oscillator (LPO) clock has a different values in
k64 vs. kw2xd, therefore we must update the clock_control driver to
parse the value from dts and convert it to the fsl_clock.h enumeration.

0d67f6a78d net: lwm2m: introduce FLAG_OPTIONAL to denote optional resources
This patch introduces several changes to support OPTIONAL resources.

The primary indicator for this behavior is to assign FLAG_OPTIONAL
to the object field's permission flags.

These resources are not setup by the LwM2M object code.  They are
left up to the user-based code for initialization via the following
functions:
lwm2m_engine_set_res_data()
lwm2m_engine_get_res_data()

When assigning const-based data as a data buffer, user-based code can
also specify the following data flag: LWM2M_RES_DATA_FLAG_RO

The FLAG_OPTIONAL flag also affects the LwM2M engine in the following
ways:
- CREATE operations won't generate an error if optional resources are
  not included.
- Object instance READ operations won't complain about missing
  optional resources.
- In the future, BOOTSTRAP operations can have different handling
  based on optional resources.

b1e45b413e subsys: fs: Add Non Volatile Storage (NVS) for zephyr
Zephyr supports fatfs, nffs and fcb as storage layer. fatfs and nffs
are less suited for application in memory restricted IC's. fcb has a
smaller footprint but has a complex api.

The proposed module is a module with a even smaller footprint compared
to fcb and a simple interface for reading and writing entries. The
module provides wear levelling of flash. This allows the module to be
used not only to store configuration settings but to store device state
(e.g. state of a light switch over reboots) of a zephyr device.

Fixes buffer overflow by introducing maximum read length in nvs_read()
and nvs_read_hist().

Fixes nvs_write() not to reflash the same data. Allows the user to do
call nvs_write() for all defined entries without worries about flash
wear.

Fixes garbage collection error where wrong data could be copied.

Add nvs_delete() to allow deleting a stored entry. A deleted entry will
not be copied to a new flash sector

Include flash wear information in the README.md documentation

0/25 Update module after reviewers remarks, added documentation to
nvs.h, removed README.md by nvs.rst in doc/subsystems folder

04/26 Update module after reviewers remarks, updated nvs.rst, added more
documentation to samples/subsys/nvs/src/main.c, updated doxygen info
in nvs.h (hope this time it works).

04/26 Update subsystems.rst to include nvs.restart

04/27 Updated nvs.c and nvs.h to avoid a possible flash deletion loop
when the file system is full.

04/29 Updated nvs_write to detect and ignore deletes of non-existing
items

05/06 Update NVS module to return standard error codes, removed low
level API, added configuration options. NVS now uses the board dts to
determine the flash storage location (FLASH_AREA_STORAGE_OFFSET).

05/06 Update nvs.rst. Updated intendation and added intermediate
variables in nvs.c to make the code easier to read.

05/06 Update nvs.rst.

05/07 Update nvs.rst

05/08 Changed the API to a more standard file system API.

05/08 Removed cnt_max from nvs_read() as it is not used.

05/08 Removed #ifdef(CONFIG_NVS_LOG) from nvs_priv.h, now the module can
be build with debugging off.

05/09 Removed configuration options for SECTOR_SIZE, SECTOR_COUNT and
MAX_ELEM_SIZE. It is now easy to support multiple NVS filesystems on
one or multiple devices. Changed logging to support newlib systems.

d22b7c9f2d Bluetooth: Remove bt_storage API
The same functionality is now supported by the settings-based
solution, so remove bt_storage out of the way. There were stubs in
bt_storage to handle per-peer information (e.g. pairing keys) but this
was never actually implemented in full. The next step is to add this
support to the settings-based solution.

Leave the code for generating temporary IRK and identity address in
case BT_SETTINGS is not enabled. Also leave the code for using vendor
HCI to read the identity address, in which case the settings
implementation will not touch it.

Introduce a new bt_unpair() API to replace the removed
bt_storage_clear(), since the latter was actually doing more than just
storage management: it was also handling runtime storage of pairing
information. Later, the bt_unpair() implementation will be extended to
clear settings-based pairing storage.

There is one feature that the bt shell module looses: the ability to
give a specific identity address to the "init" command as a parameter.
We might look later in the future if this is really needed, and add a
separate API for this.

6a71a69f8d Bluetooth: GATT: Fix CCC handling
The 'valid' member of struct bt_gatt_ccc_cfg was redundant, since
setting 'peer' to BT_ADDR_LE_ANY does the same job. What's worse, the
handling of 'valid' was also buggy in that some places looking for
valid CCC structs only matched the address, meaning it might yield a
positive match for invalid entries.

Fix these issues by removing the 'valid' struct member, and solely
using the 'peer' member to identify valid entries. Also simplify the
code by acknowledging that no CCC entry is essentially the same as the
value '0' written to CCC.

15c400774e kernel: Rework SMP irq_lock() compatibility layer
This was wrong in two ways, one subtle and one awful.

The subtle problem was that the IRQ lock isn't actually globally
recursive, it gets reset when you context switch (i.e. a _Swap()
implicitly releases and reacquires it).  So the recursive count I was
keeping needs to be per-thread or else we risk deadlock any time we
swap away from a thread holding the lock.

And because part of my brain apparently knew this, there was an
"optimization" in the code that tested the current count vs. zero
outside the lock, on the argument that if it was non-zero we must
already hold the lock.  Which would be true of a per-thread counter,
but NOT a global one: the other CPU may be holding that lock, and this
test will tell you *you* do.  The upshot is that a recursive
irq_lock() would almost always SUCCEED INCORRECTLY when there was lock
contention.  That this didn't break more things is amazing to me.

The rework is actually simpler than the original, thankfully.  Though
there are some further subtleties:

* The lock state implied by irq_lock() allows the lock to be
  implicitly released on context switch (i.e. you can _Swap() with the
  lock held at a recursion level higher than 1, which needs to allow
  other processes to run).  So return paths into threads from _Swap()
  and interrupt/exception exit need to check and restore the global
  lock state, spinning as needed.

* The idle loop design specifies a k_cpu_idle() function that is on
  common architectures expected to enable interrupts (for obvious
  reasons), but there is no place to put non-arch code to wire it into
  the global lock accounting.  So on SMP, even CPU0 needs to use the
  "dumb" spinning idle loop.

Finally this patch contains a simple bugfix too, found by inspection:
the interrupt return code used when CONFIG_SWITCH is enabled wasn't
correctly setting the active flag on the threads, opening up the
potential for a race that might result in a thread being scheduled on
two CPUs simultaneously.

3f55dafebc kernel: Deprecate k_thread_cancel() API
The only difference between this call and k_thread_abort() (beyond
some minor performance deltas) is that "cancel" will act as a noop in
cases where the thread has begun execution and will return an error.
"Abort" always succeeds, of course.  That is inherently racy when used
as a "stop the thread" API: there's no way in general (or at all in
SMP situations) to know that you're calling this function "early
enough" to catch the thread before it starts.

Effectively, all k_thread_cancel() gives you that k_thread_abort()
doesn't is an indication about whether or not a thread has started.
There are many other ways to get that information that don't require
dangerous kernel APIs.

Deprecate this function.  Zephyr's own code never used it except for
its own unit test.

8606fabf74 kernel: Scheduler refactoring: use _reschedule_*() always
There was a somewhat promiscuous pattern in the kernel where IPC
mechanisms would do something that might effect the current thread
choice, then check _must_switch_threads() (or occasionally
__must_switch_threads -- don't ask, the distinction is being replaced
by real English words), sometimes _is_in_isr() (but not always, even
in contexts where that looks like it would be a mistake), and then
call _Swap() if everything is OK, otherwise releasing the irq_lock().
Sometimes this was done directly, sometimes via the inverted test,
sometimes (poll, heh) by doing the test when the thread state was
modified and then needlessly passing the result up the call stack to
the point of the _Swap().

And some places were just calling _reschedule_threads(), which did all
this already.

Unify all this madness.  The old _reschedule_threads() function has
split into two variants: _reschedule_yield() and
_reschedule_noyield().  The latter is the "normal" one that respects
the cooperative priority of the current thread (i.e. it won't switch
out even if there is a higher priority thread ready -- the current
thread has to pend itself first), the former is used in the handful of
places where code was doing a swap unconditionally, just to preserve
precise behavior across the refactor.  I'm not at all convinced it
should exist...

The implementation is size-optimized to prioritize runtime memory
usage.  The data structure is intrusive, which is to say the struct
rbnode handle is intended to be placed in a separate struct the same
way other such structures (e.g. Zephyr's dlist list) and requires no
data pointer to be stored in the node.  The color bit is unioned with
a pointer (fairly common for such libraries).  Most notably, there is
no "parent" pointer stored in the node, the upper structure of the
tree being generated dynamically via a stack as the tree is recursed.
So the overall memory overhead of a node is just two pointers,
identical with a doubly-linked list.

Code size above dlist is about 2-2.5k on most architectures, which is
significant by Zephyr standards but probably still worthwhile in many
situations.

aa6de29c4b lib: user mode compatible mempools
We would like to offer the capability to have memory pool heap data
structures that are usable from user mode threads. The current
k_mem_pool implementation uses IRQ locking and system-wide membership
lists that make it incompatible with user mode constraints.

However, much of the existing memory pool code can be abstracted to some
common functions that are used by both k_mem_pool and the new
sys_mem_pool implementations.

The sys_mem_pool implementation has the following differences:

* The alloc/free APIs work directly with pointers, no internal memory
block structures are exposed to the end user. A pointer to the source
pool is provided for allocation, but freeing memory just requires the
pointer and nothing else.

* k_mem_pool uses IRQ locks and required very fine-grained locking in
order to not affect system latency. sys_mem_pools just use a semaphore
to protect the pool data structures at the API level, since there aren't
implications for system responsiveness with this kind of concurrency
control.

* sys_mem_pools do not support the notion of timeouts for requesting
memory.

* sys_mem_pools are specified at compile time with macros, just like
kernel memory pools. Alternative forms of specification at runtime
will be a later enhancement.

6049207a29 net: Add initial TX and RX traffic class support
With this commit it is possible to add priority to sent or received
network packets. So user is able to send or receive higher priority
packets faster than lower level packets.
The traffic class support is activated by CONFIG_NET_TC_COUNT option.
The TC support uses work queues to separate the traffic. The
priority of the work queue thread specifies the ordering of the
network traffic. Each work queue thread handles traffic to one specific
work queue. Note that you should not enable traffic classes unless
you really need them by your application. Each TC thread needs
stack so this feature requires more memory.

It is possible to disable transmit traffic class support and keep the
receive traffic class support, or vice versa. If both RX and TX traffic
classes are enabled, then both will use the same number of queues
defined by CONFIG_NET_TC_COUNT option.

ca8b00a3cc net: if: Make interface IP configuration more flexible
Instead of always allocating both IPv6 and IPv4 address information
to every network interface, allow more fine grained address
configuration. So it is possible to have IPv6 or IPv4 only network
interfaces.

This commit introduces two new config options:
CONFIG_NET_IF_MAX_IPV4_COUNT and CONFIG_NET_IF_MAX_IPV6_COUNT
which tell how many IP address information structs are allocated
statically. At runtime when network interface is setup, it is then
possible to attach this IP address info struct to a specific
network interface. This can save considerable amount of memory
as the IP address information struct can be quite large (depends
on how many IP addresses user configures in the system).

Note that the value of CONFIG_NET_IF_MAX_IPV4_COUNT and
CONFIG_NET_IF_MAX_IPV6_COUNT should reflect the estimated number of
network interfaces in the system. So if if CONFIG_NET_IF_MAX_IPV6_COUNT
is set to 1 and there are two network interfaces that need IPv6
addresses, then the system will not be able to setup IPv6 addresses to
the second network interface in this case. This scenario might be
just fine if the second network interface is IPv4 only. The net_if.c
will print a warning during startup if mismatch about the counts and
the actual number of network interface is detected.

This was originally added as a work-around to avoid the heavy stack
consumption of the TinyCrypt PRNG when generating NRPAs. This is
no-longer an issue, and there are in fact no (in-tree) users of this.
Remove it before it gains any wider users, since it was in many ways a
hack/work-around to begin with.

16921b0698 usb: Add transfer management API
The transfer API provides 'high' level functions to manage sending and
reception of USB data. A USB (class) driver has to register the generic
usb_transfer_ep_callback as endpoint status callback in order to use
the API.

With this API, the class driver does not need to take care of low-level
usb transfer management (packet splitting, ZLP, synchronization...).
The usb_transfer methods will split transfer into multiple transactions
depending endpoint max size and controller capabilities.

Once the transfer is completed, class driver is notified by a callback.
The usb_transfer method can be executed in IRQ/atomic context.
A usb_transfer synchronous helper exists which block-waits until
transfer completion.

In write case, a transfer is complete when all data has been sent.
In read case, a transfer is complete when the exact amount of data
requested has been received or if a short-pkt (including ZLP) is
received.

transfer methods are thread-safe.

A transfer can be cancelled at any time.

6eef2f1485 misc: Add a FORCE_NO_ASSERT kconfig directive
The mbedtls test is hitting a compiler bug where two subtests will
soft fail on qemu_xtensa when assertions are enabled.  This is despite
the fact that:

+ The failure is entirely internal to the mbedtls suite.
+ The mbedtls code does not use zephyr asserts
+ The mbedtls code does not call into zephyr code that might assert.
+ The behavior persists even when an irq_lock() is held across the
  entire test, ruling out any asserts in interrupt/exception context.
+ And EVEN WHEN the mbedtls library blobs are bytewise identical
  between assert and non-assert cases.

The bug seems to be a layout thing where the mbedtls code behavior
differently based on code address and/or link-time optimizations
(xtensa has a few).

Unfortunately sanitycheck enables assertions by setting CFLAGS
directly and not via kconfig, so we can't fix this by turning the
feature off in an app right now.  This patch adds a simple "override"
flag that can be set by apps like this that hit bugs.

Again, note that zephyr assertions are not used nor needed by this one
test.

3f5027f835 xtensa: Fix noreturn attribute on error handlers in asm2
In asm2, the machine exception handler runs in interrupt context (this
is good: it allows us to defer the test against exception type until
after we have done the stack switch and dispatched any true
interrupts), but that means that the user error handler needs to be
invoked and then return through the interrupt exit code.

So the __attribute__(__noreturn__) that it was being decorated with
was incorrect.  And actually fatal, as with gcc xtensa will crash
trying to return from a noreturn call.

2724fd11cb kernel: SMP-aware scheduler
The scheduler needs a few tweaks to work in SMP mode:

1. The "cache" field just doesn't work.  With more than one CPU,
   caching the highest priority thread isn't useful as you may need N
   of them at any given time before another thread is returned to the
   scheduler.  You could recalculate it at every change, but that
   provides no performance benefit.  Remove.

2. The "bitmask" designed to prevent the need to individually check
   priorities is likewise dropped.  This could work, but in fact on
   our only current SMP system and with current K_NUM_PRIOPRITIES
   values it provides no real benefit.

3. The individual threads now have a "current cpu" and "active" flag
   so that the choice of the next thread to run can correctly skip
   threads that are active on other CPUs.

The upshot is that a decent amount of code gets #if'd out, and the new
SMP implementations for _get_highest_ready_prio() and
_get_next_ready_thread() are simpler and smaller, at the expense of
having to drop older optimizations.

Note that scheduler synchronization is unchanged: all scheduler APIs
used to require that an irq_lock() be held, which means that they now
require the global spinlock via the same API.  This should be a very
early candidate for lock granularity attention!

364cbae412 kernel: Make irq_{un}lock() APIs into a global spinlock in SMP mode
In SMP mode, the idea of a single "IRQ lock" goes away.  Long term,
all usage needs to migrate to spinlocks (which become simple IRQ locks
in the uniprocessor case).  For the near term, we can ease the
migration (at the expense of performance) by providing a compatibility
implementation around a single global lock.

Note that one complication is that the older lock was recursive, while
spinlocks will deadlock if you try to lock them twice.  So we
implement a simple "count" semantic to handle multiple locks.

k_spinlock_t to un/lock.  No attempt at implementing fairness or
backoff semantics.  No attempt made at architecture-specific assembly.

When CONFIG_SMP is not enabled, this code falls back to a zero-size
struct and becomes functionally identical to irq_lock/unlock().

042d8ecca9 kernel: Add alternative _arch_switch context switch primitive
The existing __swap() mechanism is too high level for some
applications because of its scheduler-awareness.  This introduces a
new _arch_switch() mechanism, which is a simpler primitive that looks
like:

    void _arch_switch(void *handle, void **old_handle_out);

The new thread handle (typically just a stack pointer) is specified
explicitly instead of being picked up from the scheduler by
per-architecture code, and on return the "old" thread handle that got
switched out is returned through the pointer.

The new primitive (currently available only on xtensa) is selected
when CONFIG_USE_SWITCH is "y".  A new C _Swap() implementation based
on this primitive is then added which operates compatibly.

bb50a88045 arch: arc: apply the new thread stack layout
The new thread stack layout is as follow:

|---------------------|
|  user stack         |
|---------------------|
| stack guard (opt.)  |
|---------------------|
|  privilege stack    |
-----------------------

For MPUv2
  * user stack is aligned to the power of 2 of user stack size
  * the stack guard is 2048 bytes
  * the default size of privileg stack is 256 bytes.
  For user thread, the following MPU regions are needded
    * one region for user stack, no need of stack guard for user stack
    * one region for stack guard when stack guard is enbaled
    * regions for memory domain.
  For kernel thread, the stack guard region will be at the top, adn
  The user stack and privilege stack will be merged.

MPUv3 is the same as V2's layout, except no need of power of 2
alignment.

* reimplement the user mode enter function. Now it's possible for
kernel thread to drop privileg to user thread.

* add a separate entry for user thread

* bug fixes in the cleanup of regs when go to user mode

03c1d28e6e work_q: Correctly clear pending flag in delayed work queue, update docs
As discovered in https://github.com/zephyrproject-rtos/zephyr/issues/5952

...a duplicate call to k_delayed_work_submit_to_queue() on a work item
whose timeout had expired but which had not yet executed (i.e. it was
pending in the queue for the active work queue thread) would fail,
because the cancellation step wouldn't clear the PENDING bit, causing
the resubmission to see the object in an invalid state.  Trivially
fixed by adding a bit clear.

It also turns out that the behavior of the code doesn't match the
docs, which state that a PENDING work item is not supposed to be
cancelled at all.  Fix the docs to remove that.

And on yet further review, it turns out that there's no way to make a
test like the one in the linked bug threadsafe.  The work queue does
no synchronization by design, so if the user code does no external
synchronization it might very well clobber the running handler.  Added
a sentence to the docs to reflect this gotcha.

e3cd915d8f fs: Convert FCB to use sectors (not areas)
Prior to this commit: `struct fcb` contained a pointer to an array of
`struct flash_area`.  Each entry in the array represented a flash sector
that the fcb comprised.

After commit: `struct fcb` contains a pointer to an array of `struct
flash_sector`, not `struct flash_area`.

Rationale: The FCB needs to know which sectors it occupies for its
rotate operation.  However, the `flash_area` type is meant to represent
a collection of sectors, not a single sector.  `struct flash_area`
contains information that the fcb does not need (e.g., area ID and
device ID).  Furthermore, the flash_map API provides a means of
converting a flash area ID to an array of sectors
(`flash_area_get_sectors()`), but no way to convert to an array of
areas.

01aa12bffd dfu: mcuboot: add boot_is_img_confirmed()
Applications chainloaded by MCUboot may want to change their behavior
based on whether or not they are confirmed.

Here are some examples:

  - performing a built-in self test (BIST) if the image is not yet
    confirmed, and marking it OK if it passes (this enables reverting
    to an older working image if the BIST fails, and allows future
    resets to skip the BIST if it passes to improve boot time)

  - interacting with persistent metadata related to image state on
    other flash partitions during test upgrades (these are required in
    cases when the update source provides runtime metadata, such as
    monotonic counters, related to an upgrade attempt which must be
    used to report results)

To enable these use cases, add boot_is_img_confirmed(), which reads
the "image OK" field for the current firmware image and returns true
if and only if it is set.

This patch does several things, most notably it changes the semantics
of CONFIG_DEBUG. CONFIG_DEBUG continues to behave as a vaguely defined
"debug mode" that enables printf's, -Og, etc. but now the user may
choose to be in "debug mode" while using a different optimization
level than -Og.

Tp support this a new config is defined to enable -Og;
CONFIG_DEBUG_OPTIMIZATIONS.

Additionally CONFIG_SIZE_OPTIMIZATIONS is introduced to allow the user
to explicitly request optimizing for size instead of relying on
defaulting to it.

The three config's {NO,SIZE,DEBUG}_OPTIMIZATIONS are now organized in
a Kconfig choice to ensure that at most one can be enabled at a time.

b7623a85b0 sensors: Redefine SENSOR_CHAN_HUMIDITY in percents, not milli-percents.
Based on the discussion in #5693, the reason why humidity was defined
in milli-percent was likely following Linux which defines it as such
in its sensor subsystem:
http://elixir.free-electrons.com/linux/latest/source/Documentation/ABI/testing/sysfs-bus-iio#L263

However, Linux defines temperature in milli-degrees either, but
Zephyr uses degrees (similarly for most other quantities). Typical
sensor resolution/precision for humidity is also on the order of 1%.

One of the existing drivers, th02.c, already returned values in
percents, and few apps showed it without conversion and/or units,
leading to confusing output to user like "54500".

So, switching units to percents, and update all the drivers and
sample apps.

For few drivers, there was also optimized conversion arithmetics
to avoid u64_t operations. (There're probably more places to
optimize it, and temperature conversion could use such optimization
too, but that's left for another patch.)

Fixes: #5693

f4e08b003c net: sockets: Define POSIX function symbols as inline functions
Previously, POSIX function names were aliased to zsock_ function
names using, for example:

	#define connect zsock_connect

This caused the C preprocessor to replace any symbol named 'connect',
whether a function or not, in all source code which included socket.h,
with 'zsock_connect'.  This generated unintended code where the symbol
'connect' was used as the name of a structure field (as in mqtt.h).

This new inline definition is applied to all the POSIX function symbols,
with the exception of fcntl, a redefinition of which would conflict
with the definiton in the toolchain's fcntl.h.

Before going to add another address type, there was an attempt
to repurpose TENTATIVE address state, but it doesn't work as

have clearly semantics, and it makes sense to just another
address type to avoid confusion and unexpected behavior.

CC1200 is a sub-ghz chip supporting 6 ISM & SRD bands: 169, 433, 470,
868, 915 and 920 MHz, with features dedicated to IEEE 802.15.4(g).

Current driver enables CC1200 against actual IEEE 802.15.4 Soft-MAC. 'g'
version support in the Soft-MAC will follow later.

The chip itself is closer to a bare metal radio modem than to a usual
15.4 chip: up to the user to provide the right RF settings for the
carrier band. Such settings can be generaten through TI's SmartRF tool.

Hopefully, for channel selection, this driver will be clever enough to
compute the proper register change without any special input from the
user. This will work for all the bands supported by the chip.

1c2de10c06 cmake: ninja: Change how CMake names the kernelspace archives
The linker script places kernelspace and userspace archives in

what archives are in what space, that is done by CMake.

CMake passes the list of kernelspace archives to the linker script

-DNUM_KERNEL_OBJECT_FILES=3
-DKERNEL_OBJECT_FILE_0=path/to/archive_a.a
-DKERNEL_OBJECT_FILE_1=path/to/archive_b.a
-DKERNEL_OBJECT_FILE_2=path/to/archive_c.a

These paths are relative, and since Ninja and Make invoke the linker
with different "working directories"[0], the relative paths need to be
different. This patch rectifies the relative path when using Ninja.

528c960ae7 arch: arc: Add the support of secure mode for em
In ARC's SecureShield, a new secure mode (currently only em) is added.
The secure/normal mode is orthogonal to kernel/user mode. The
differences between secure mode and normal mode are following:

* different irq stack frame. so need to change the definition of
  _irq_stack_frame, assembly code.

* new aux regs, e.g, secure status(SEC_STAT), secure vector base
  (VECT_BASE_S)

* interrupts and exceptions, secure mode has its own vector base;
  interrupt can be configured as secure or normal through the
  interrupt priority aux reg.

* secure timers. Two secure timers (secure timer 0 and timer 1) are
  added.Here, for simplicity and backwards compatibility original
  internal timers (timer 0 and timer1) are used as sys clock of zephyr

* on reset, the processor is in secure mode and secure vector base is
  used.

Note: the mix of secure and normal mode is not supported, i.e. it's
assumed that the processor is always in secure mode.

15fe221f13 Bluetooth: Mesh: Fix accuracy of Publish Period
After the Publish Retransmit state was introduced the Publish Period
measurement would begin once the previous Publish message has finished
transmitting. This will however cause inaccurate periods, which is
particularly an issue with the PTS that expects accuracy of less than
0.5 seconds (apparently).

Since the publication timer is also used for the retransmissions we
can't simultaneously use if for the period as well. Therefore, we
introduce a new variable called period_start which makes a note of
when the period was supposed to start, and then once all
retransmissoins are done initializes the timer with the send duration
taken into account.

8f1541184f Bluetooth: Mesh: Fix non-periodic Model Publication
The only generally available model supporting publication that's
convenient to be used for testing is the Health Server Model.
Unfortunately since this model supports period publication, the
non-periodic side got less attention and had some bugs.

The first thing that needs to be done is to verify that the period
returned by bt_mesh_model_pub_period_get() is positive. If it's zero
then no periodic publication should take place.

Another thing that this patch cleans up is the naming of the callback
used for periodic publishing. There's no need do require the callback
to call bt_mesh_model_publish() since this must happen no matter what,
so instead rename the callback from 'func' to 'update' and have the
access layer call bt_mesh_model_publish() if the callback was
successful.

e7bb76e2b6 Bluetooth: Mesh: Fix model publication
Model publication was broken in a couple of ways:

 - The Publish Retransmit State was not taken into account at all
 - Health Server used a single publish state for all elements

To implement Publish Retransmit properly, one has to use a callback to
track when the message has been sent. The problem with the transport
layer sending APIs was that giving a callback would cause the
transport layer to assume that segmentation (with acks) is desired,
which is not the case for Model Publication (unless the message itself
is too large, of course). Because of this, the message sending context
receives a new send_rel ("Send Reliable") boolean member that an app
can use to force reliable sending.

Another challenge with the Publish Retransmit state is that a buffer
is needed for storing the AppKey-encrypted SDU once it has been sent
out for the first time.To solve this, a new new net_buf_simple member
is added to the model publication context. The separate 'msg' input
parameter of the bt_mesh_model_publish() API is removed, since the
application is now expected to pre-fill pub->msg instead.

To help with the publishing API change, the Health Server model gets a
new helper macro for initializing the publishing context with a
right-sized publishing message.

The API for creating Health Server instances is also redesigned since
it was so far using a single model publishing state, which would
result in erratic behavior in case of multiple elements with the
Health Server Model. Now, the application needs to provide a unique
publishing context for each Health Server instance.

The changes are heavily intertwined, so it's not easily possible to
split them into multiple patches, hence the large(ish) patch.

the timeout may be changed at run-time (mainly useful for the shell).

Note: The timeout_set() API is normally assumed to be called just once
for an application, based on the expected size of the network (hops &
latency). Trying to change it e.g. in a multi-threaded environment for
every message may not yield the expected results.

If CONFIG_USERSPACE is enabled, stack overflows will still be
caught in some situations:

1) User mode threads overflowing stack, since it crashes into the
kernel stack page
2) Supervisor mode threads overflowing stack, since the kernel
stack page is marked non-present for non-user threads

Stack overflows will not be caught:

1) When handling a system call
2) When the interrupt stack overflows

9bb07ff69a jailhouse: add support for x2APIC mode for all LOAPIC accesses
Besides the fact that we did not have that for the current supported
boards, that makes sense for this new, virtualized mode, that is meant
to be run on top of full-fledged x86 64 CPUs.

By having xAPIC mode access only, Jailhouse has to intercept those MMIO
reads and writes, in order to examine what they do and arbitrate if it's
safe or not (e.g. not all values are accepted to ICR register). This
means that we can't run away from having a VM-exit event for each and
every access to APIC memory region and this impacts the latency the
guest OS observes over bare metal a lot.

When in x2APIC mode, Jailhouse does not require VM-exits for MSR
accesses other that writes to the ICR register, so the latency the guest
observes is reduced to almost zero.

Here are some outputs of the the command line

  $ sudo ./tools/jailhouse cell stats tiny-demo

on a Jailhouse's root cell console, for one of the Zephyr demos using
LOAPIC timers, left for a couple of seconds:

See that under x2APIC mode on both Jailhouse/root-cell and guest, the
interruptions from the hypervisor are minimal. That is not the case when
Jailhouse is on xAPIC mode, though. Note also that, as a plus, x2APIC
accesses on the guest will map to xAPIC MMIO on the hypervisor just
fine.

97a8716a4f x86: Jailhouse port, tested for UART (# 0, polling) and LOAPIC timer
This is an introductory port for Zephyr to be run as a Jailhouse
hypervisor[1]'s "inmate cell", on x86 64-bit CPUs (running on 32-bit
mode). This was tested with their "tiny-demo" inmate demo cell
configuration, which takes one of the CPUs of the QEMU-VM root cell
config, along with some RAM and serial controller access (it will even
do nice things like reserving some L3 cache for it via Intel CAT) and
Zephyr samples:

   - hello_world
   - philosophers
   - synchronization

The final binary receives an additional boot sequence preamble that
conforms to Jailhouse's expectations (starts at 0x0 in real mode). It
will put the processor in 32-bit protected mode and then proceed to
Zephyr's __start function.

Testing it is just a matter of:
  $ mmake -C samples/<sample_dir> BOARD=x86_jailhouse JAILHOUSE_QEMU_IMG_FILE=<path_to_image.qcow2> run
  $ sudo insmod <path to jailhouse.ko>
  $ sudo jailhouse enable <path to configs/qemu-x86.cell>
  $ sudo jailhouse cell create <path to configs/tiny-demo.cell>
  $ sudo mount -t 9p -o trans/virtio host /mnt
  $ sudo jailhouse cell load tiny-demo /mnt/zephyr.bin
  $ sudo jailhouse cell start tiny-demo
  $ sudo jailhouse cell destroy tiny-demo
  $ sudo jailhouse disable
  $ sudo rmmod jailhouse

For the hello_world demo case, one should then get QEMU's serial port
output similar to:

"""
Created cell "tiny-demo"
Page pool usage after cell creation: mem 275/1480, remap 65607/131072
Cell "tiny-demo" can be loaded
CPU 3 received SIPI, vector 100
Started cell "tiny-demo"
***** BOOTING ZEPHYR OS v1.9.0 - BUILD: Sep 12 2017 20:03:22 *****
Hello World! x86
"""

Note that the Jailhouse's root cell *has to be started in xAPIC
mode* (kernel command line argument 'nox2apic') in order for this to
work. x2APIC support and its reasoning will come on a separate commit.

As a reminder, the make run target introduced for x86_jailhouse board
involves a root cell image with Jailhouse in it, to be launched and then
partitioned (with >= 2 64-bit CPUs in it).

Inmate cell configs with no JAILHOUSE_CELL_PASSIVE_COMMREG flag
set (e.g. apic-demo one) would need extra code in Zephyr to deal with
cell shutdown command responses from the hypervisor.

You may want to fine tune CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC for your
specific CPU—there is no detection from Zephyr with regard to that.

Other config differences from pristine QEMU defaults worth of mention
are:

   - there is no HPET when running as Jailhouse guest. We use the LOAPIC
     timer, instead
   - there is no PIC_DISABLE, because there is no 8259A PIC when running
     as a Jailhouse guest
   - XIP makes no sense also when running as Jailhouse guest, and both
     PHYS_RAM_ADDR/PHYS_LOAD_ADD are set to zero, what tiny-demo cell
     config is set to

This opens up new possibilities for Zephyr, so that usages beyond just
MCUs come to the table. I see special demand coming from
functional-safety related use cases on industry, automotive, etc.

818a96d3af userspace: assign thread IDs at build time
Kernel object metadata had an extra data field added recently to
store bounds for stack objects. Use this data field to assign
IDs to thread objects at build time. This has numerous advantages:

* Threads can be granted permissions on kernel objects before the
  thread is initialized. Previously, it was necessary to call
  k_thread_create() with a K_FOREVER delay, assign permissions, then
  start the thread. Permissions are still completely cleared when
  a thread exits.

* No need for runtime logic to manage thread IDs

* Build error if CONFIG_MAX_THREAD_BYTES is set too low

b007b64d30 kernel: Add option to ensure writable pages are not executable
This adds CONFIG_EXECUTE_XOR_WRITE, which is enabled by default on
systems that support controlling whether a page can contain executable
code.  This is also known as W^X[1].

Trying to add a memory domain with a page that is both executable and
writable, either for supervisor mode threads, or for user mode threads,
will result in a kernel panic.

There are few cases where a writable page should also be executable
(JIT compilers, which are most likely out of scope for Zephyr), so an
option is provided to disable the check.

Since the memory domain APIs are executed in supervisor mode, a
determined person could bypass these checks with ease.  This is seen
more as a way to avoid people shooting themselves in the foot.

f801c1ca8e net: buf: Add net_buf_id() API
Add a net_buf_id() API which translates a buffer into a zero-based
index, based on its placement in the buffer pool. This can be useful
if you want to associate an external array of meta-data contexts with
the buffers of a pool.

The added value of this API is slightly limited at the moment, since
the net_buf API allows custom user-data sizes for each pool (i.e. the
user data can be used instead of a separately allocated meta-data
array). However, there's some refactoring coming soon which will unify
all net_buf structs to have the same fixed (and typically small)
amount of user data. In such cases it may be desirable to have
external user data in order not to inflate all buffers in the system
because of a single pool needing the extra memory.

_POLL_NUM_TYPES & _POLL_NUM_STATES are values of an enum, which the
preprocessor does not know about.
But the first of the removed lines needs to be evaluated by the
preprocessor using them.

The result is that the preprocessor will treat _POLL_NUM_TYPES
and _POLL_NUM_STATES as 0 in that expression, which would not seem the
intended behavior. It will also produce 2 warnings about this in each
file which includes kernel.h (lots)

=> lines 3779-3781 are be removed.

Previously net_pkt.h, defined macros NET_PKT_TX_SLAB_DEFINE,
NET_PKT_DATA_POOL_DEFINE, but advertised them as intended for
"user specified data". However, net_pkt.c effectively used the
same parameters for slabs/pools, but this wasn't obvious due
to extra config param redirection. So, make following changes:

1. Rename NET_PKT_TX_SLAB_DEFINE() to NET_PKT_SLAB_DEFINE()
as nothing in its definition is TX-specific.
2. Remove extra indirection for config params, and use
NET_PKT_SLAB_DEFINE and NET_PKT_DATA_POOL_DEFINE to define
system pools.
3. Update docstrings for NET_PKT_SLAB_DEFINE and
NET_PKT_DATA_POOL_DEFINE.

Overall, this change removes vail of magic in the definition of
system pkt slabs/pools, making obvious the fact that any packet
slabs/pools - whether default system or additional, custom - are
defined in exactly the same manner (and thus work in the same manner
too).
