532cbacc27 net: Add function to parse IP address string
The net_ipaddr_parse() will take a string with optional port
number and convert its information into struct sockaddr.
The format of the IP string can be:
     192.0.2.1:80
     192.0.2.42
     [2001:db8::1]:8080
     [2001:db8::2]

ecb0f3e159 arm: mpu: Account for stack guard size correctly
This patch fixes a couple of issues with the stack guard size and
properly constructs the STACK_ALIGN and STACK_ALIGN_SIZE definitions.

The ARM AAPCS requires that the stack pointers be 8 byte aligned.  The
STACK_ALIGN_SIZE definition is meant to contain the stack pointer
alignment requirements.  This is the required alignment at public API
boundaries (ie stack frames).

The STACK_ALIGN definition is the required alignment for the start
address for stack buffer storage.  STACK_ALIGN is used to validate
the allocation sizes for stack buffers.

The MPU_GUARD_ALIGN_AND_SIZE definition is the minimum alignment and
size for the MPU.  The minimum size and alignment just so happen to be
32 bytes for vanilla ARM MPU implementations.

When defining stack buffers, the stack guard alignment requirements
must be taken into consideration when allocating the stack memory.
The __align() must be filled in with either STACK_ALIGN_SIZE or the
align/size of the MPU stack guard.  The align/size for the guard region
will be 0 when CONFIG_MPU_STACK_GUARD is not set, and 32 bytes when it
is.

The _ARCH_THREAD_STACK_XXXXXX APIs need to know the minimum alignment
requirements for the stack buffer memory and the stack guard size to
correctly allocate and reference the stack memory.  This is reflected
in the macros with the use of the STACK_ALIGN definition and the
MPU_GUARD_ALIGN_AND_SIZE definition.

4fea5b18ab net: app: Add IP header to packets received by TLS/DTLS tunnel
The IP header was stripped by _net_app_ssl_mux() when it received
IP packet. This is fine but if the application expects the get
the IP header, then there is a problem. Fix this by saving IP
header to ssl_context and then putting it back in front of the
packet when the data is passed to application.
Note that this IP header is not used by net_app when the packet
is sent because TLS/DTLS creates a tunnel for transferring packets
and user can only sent packets via this tunnel.

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

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

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

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

53c859998d kernel: POSIX thread IPC support
Partial implementation of the IEEE 1003.1 pthread API, including
mutexes and condition variables in their default behaviors, and
pthread barrier objects.  The rwlock and spinlocks abstractions are
not supported in this commit (both only make sense in the presence of
multiple SMP processors).

Note that this is the IPC mechanisms only.  The thread creation API
itself is unsupported: Zephyr threads work differently from pthreads
and don't port cleanly in all cases.  Likewise the "_INITIALIZER"
macros from pthreads don't work cleanly here, and _DECLARE macros have
been provided to statically initialize pthread primitives in a manner
more native to Zephyr

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Each member of the array may need to have a padding size added

This would mean that sizeof(some array element) would return
a larger size than what was originally provided.

This won't cause problems at runtime since the space is really
there, but for users who are only enabling this padding for
debug features, they may be surprised when their stacks are

 - Low Power Node support (lpn.c)
 - Relay support (net.c)
 - GATT Proxy (proxy.c)

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

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

2cb03c5cd6 toolchain.h: fix __in_section_unique()
_FILE_PATH_HASH appears to be a legacy Diab-ism that doesn't
expand to anything in GCC.

As a result, when linking the combined binary, it's quite
possible that objects in separate C files would be merged
instead of truly being in their own section. This can confound
--gc-sections and result in unused objects still being in
the final binary if one of the other objects with the same
generated section name was actually used.

We instead just use __FILE__. This results in sometimes absurdly-
long section names in the intermediate .o files, but there is no
actual limit to how long section names in ELF binaries can be;
they are not stored directly in headers but instead referenced
as an offset in the .shstrtab section, which has all the section
names stored in it.

02f021068f linker/common-ram.ld: force input section align
These special kernel sections represent arrays of kernel objects than
are iterated over at runtime to perform initialization.

The code expects all the data in these sections to be in the form of an
array of that section type, with each element sizeof(type) bytes apart.

Unfortunately, the linker sometimes has other plans and in some cases
was defaulting to aligning the data to some large power-of-two value,
such as 64 bytes. This causes any attempt to iterate over these sections
to fail as they are not a proper array.

Use the ld SUBALIGN() directive to force the alignment of these input
sections to 4 bytes.

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

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

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

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

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

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

As explained in the docstrings, a usecase behind these operations is
when other container objects are put in a fifo. The typical
processing iteration make take just some data from a container at
the head of fifo, with the container still being kept at the fifo,
unless it becomes empty, and only then it's removed. Similarly with
adding more data - first step may be to try to add more data to a
container at the tail of fifo, and only if it's full, add another
container to a fifo.

The specific usecase these operations are added for is network
subsystem processing, where net_buf's and net_pkt's are added

* There's unavoidable need to have a per-socket queue of packets

These queues share the same space (as a C union).
* There's a need to track "EOF" status of connection, synchronized
with a queue of pending packets (i.e. EOF status should be processed
only when all pending packets are processed). A natural place to
store it per-packet then, and we had a "sent" bit which was used
only for outgoing packets, recast it as "eof" for incoming socket

Clearing fields in the region descriptor attributes doesn't always have
the expected effect of revoking permissions. In the case of bus master
supervisor mode fields (MxSM), setting to zero actually enables read,
write, and execute access.

When we reworked handling of region descriptor 0, we inadvertently
enabled execution from RAM by clearing the MxSM fields and enabling the
descriptor. This caused samples/mpu_test run to throw a usage fault
instead of an MPU-triggered bus fault.

Fix this by setting all the MxSM fields to 2'b11, which gives supervisor
mode the same access as user mode.

515788648a net: ip: Make struct in_addr::s_addr compatible with POSIX definition
From
http://pubs.opengroup.org/onlinepubs/7908799/xns/netinetin.h.html:

in_addr_t
    An unsigned integral type of exactly 32 bits.

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

in_addr_t      s_addr

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

EEPROM read mode is a specific mode where the controller will TX a

The gain relies in the controller generating all necessary dummy bytes
by itself to read data the from slave, it will only generate RX
interrupts. Thus reducing CPU work.
Obviously TX and RX buffers should be relevantly provided by the user.

If not supported by the controller, the driver can still work (it will
have to generate the dummy bytes) and thus -EINVAL should not be

73cb9586ce k_mem_pool: Complete rework
This patch amounts to a mostly complete rewrite of the k_mem_pool
allocator, which had been the source of historical complaints vs. the
one easily available in newlib.  The basic design of the allocator is
unchanged (it's still a 4-way buddy allocator), but the implementation
has made different choices throughout.  Major changes:

Space efficiency: The old implementation required ~2.66 bytes per
"smallest block" in overhead, plus 16 bytes per log4 "level" of the
allocation tree, plus a global tracking struct of 32 bytes and a very
surprising 12 byte overhead (in struct k_mem_block) per active
allocation on top of the returned data pointer.  This new allocator
uses a simple bit array as the only per-block storage and places the
free list into the freed blocks themselves, requiring only ~1.33 bits
per smallest block, 12 bytes per level, 32 byte globally and only 4
bytes of per-allocation bookeeping.  And it puts more of the generated
tree into BSS, slightly reducing binary sizes for non-trivial pool
sizes (even as the code size itself has increased a tiny bit).

IRQ safe: atomic operations on the store have been cut down to be at
most "4 bit sets and dlist operations" (i.e. a few dozen
instructions), reducing latency significantly and allowing us to lock
against interrupts cleanly from all APIs.  Allocations and frees can
be done from ISRs now without limitation (well, obviously you can't
sleep, so "timeout" must be K_NO_WAIT).

Deterministic performance: there is no more "defragmentation" step
that must be manually managed.  Block coalescing is done synchronously
at free time and takes constant time (strictly log4(num_levels)), as
the detection of four free "partner bits" is just a simple shift and
mask operation.

Cleaner behavior with odd sizes.  The old code assumed that the
specified maximum size would be a power of four multiple of the
minimum size, making use of non-standard buffer sizes problematic.
This implementation re-aligns the sub-blocks at each level and can
handle situations wehre alignment restrictions mean fewer than 4x will
be available.  If you want precise layout control, you can still
specify the sizes rigorously.  It just doesn't break if you don't.

More portable: the original implementation made use of GNU assembler
macros embedded inline within C __asm__ statements.  Not all
toolchains are actually backed by a GNU assembler even when the
support the GNU assembly syntax.  This is pure C, albeit with some
hairy macros to expand the compile-time-computed values.

Related changes that had to be rolled into this patch for bisectability:

* The new allocator has a firm minimum block size of 8 bytes (to store
  the dlist_node_t).  It will "work" with smaller requested min_size
  values, but obviously makes no firm promises about layout or how
  many will be available.  Unfortunately many of the tests were
  written with very small 4-byte minimum sizes and to assume exactly
  how many they could allocate.  Bump the sizes to match the allocator
  minimum.

* The mbox and pipes API made use of the internals of k_mem_block and
  had to be ported to the new scheme.  Blocks no longer store a
  backpointer to the pool that allocated them (it's an integer ID in a
  bitfield) , so if you want to "nullify" them you have to use the
  data pointer.

* test_mbox_api had a bug were it was prematurely freeing k_mem_blocks
  that it sent through the mailbox.  This worked in the old allocator
  because the memory wouldn't be touched when freed, but now we stuff
  list pointers in there and the bug was exposed.

* Remove test_mpool_options: the options (related to defragmentation
  behavior) tested no longer exist.

174f301147 build: simplfy how extra build steps are specified
For various reasons its often necessary to generate certain
complex data structures at build-time by separate tools outside
of the C compiler. Data is populated to these tools by way of
special binary sections not intended to be included in the final
binary. We currently do this to generate interrupt tables, forthcoming
work will also use this to generate MMU page tables.

The way we have been doing this is to generatea "kernel_prebuilt.elf",
extract the metadata sections with objcopy, run the tool, and then
re-link the kernel with the extra data *and* use objcopy to pull
out the unwanted sections.

This doesn't scale well if multiple post-build steps are needed.
Now this is much simpler; in any Makefile, a special
GENERATED_KERNEL_OBJECT_FILES variable may be appended to containing
the filenames to the generated object files, which will be generated
by Make in the usual fashion.

Instead of using objcopy to pull out, we now create a linker-pass2.cmd
which additionally defines LINKER_PASS2. The source linker script
can #ifdef around this to use the special /DISCARD/ section target
to not include metadata sections in the final binary.

0fdc9b5b12 drivers: serial: Clarify usage of TX/RX IRQ predicates.
uart_irq_tx_empty() function proved to be problematic: its semantics
was not documented properly, and many hardware uses terminology like
"TX register empty" to signify condition of TX register being ready
to accept another character (what in Zephyr is tested with
uart_irq_tx_ready()). To avoid confusion, uart_irq_tx_empty() was
renamed to uart_irq_tx_complete(), propagating to drivers/serial
device methods.

The semantics and usage model of all of uart_irq_rx_ready(),
uart_irq_tx_ready(), uart_irq_tx_complete() is now described in
detail.

d26cf2dc33 kernel: add k_thread_create() API
Unline k_thread_spawn(), the struct k_thread can live anywhere and not
in the thread's stack region. This will be useful for memory protection
scenarios where private kernel structures for a thread are not
accessible by that thread, or we want to allow the thread to use all the
stack space we gave it.

This requires a change to the internal _new_thread() API as we need to
provide a separate pointer for the k_thread.

By default, we still create internal threads with the k_thread in stack
memory. Forthcoming patches will change this, but we first need to make
it easier to define k_thread memory of variable size depending on
whether we need to store coprocessor state or not.

3f50707672 kernel: queue, fifo: Add cancel_wait operation.
Currently, a queue/fifo getter chooses how long to wait for an
element. But there are scenarios when putter would know better,
there should be a way to expire getter's timeout to make it run
again. k_queue_cancel_wait() and k_fifo_cancel_wait() functions
do just that. They cause corresponding *_get() functions to return
with NULL value, as if timeout expired on getter's side (even
K_FOREVER).

This can be used to signal out of band conditions from putter to
getter, e.g. end of processing, error, configuration change, etc.
A specific event would be communicated to getter by other means
(e.g. using existing shared context structures).

Without this call, achieving the same effect would require e.g.
calling k_fifo_put() with a pointer to a special sentinal memory
structure - such structure would need to be allocated somewhere
and somehow, and getter would need to recognize it from a normal
data item. Having cancel_wait() functions offers an elegant
alternative. From this perspective, these calls can be seen as
an equivalent to e.g. k_fifo_put(fifo, NULL), except that such
call won't work in practice.

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

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

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

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

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

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

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

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

89ffd44dfb kernel: tickless: Add tickless kernel support
Adds event based scheduling logic to the kernel. Updates
management of timeouts, timers, idling etc. based on
time tracked at events rather than periodic ticks. Provides
interfaces for timers to announce and get next timer expiry
based on kernel scheduling decisions involving time slicing
of threads, timeouts and idling. Uses wall time units instead
of ticks in all scheduling activities.

The implementation involves changes in the following areas

1. Management of time in wall units like ms/us instead of ticks
The existing implementation already had an option to configure
number of ticks in a second. The new implementation builds on
top of that feature and provides option to set the size of the
scheduling granurality to mili seconds or micro seconds. This
allows most of the current implementation to be reused. Due to
this re-use and co-existence with tick based kernel, the names
of variables may contain the word "tick". However, in the
tickless kernel implementation, it represents the currently
configured time unit, which would be be mili seconds or
micro seconds. The APIs that take time as a parameter are not
impacted and they continue to pass time in mili seconds.

2. Timers would not be programmed in periodic mode
generating ticks. Instead they would be programmed in one
shot mode to generate events at the time the kernel scheduler
needs to gain control for its scheduling activities like
timers, timeouts, time slicing, idling etc.

3. The scheduler provides interfaces that the timer drivers
use to announce elapsed time and get the next time the scheduler
needs a timer event. It is possible that the scheduler may not
need another timer event, in which case the system would wait
for a non-timer event to wake it up if it is idling.

4. New APIs are defined to be implemented by timer drivers. Also
they need to handler timer events differently. These changes
have been done in the HPET timer driver. In future other timers
that support tickles kernel should implement these APIs as well.
These APIs are to re-program the timer, update and announce
elapsed time.

5. Philosopher and timer_api applications have been enabled to
test tickless kernel. Separate configuration files are created
which define the necessary CONFIG flags. Run these apps using
following command
make pristine && make BOARD=qemu_x86 CONF_FILE=prj_tickless.conf qemu
