700c313ce7 net: buf: Use TCP sent_list variable only if needed
If TCP is not enabled, then compile out the TCP retransmit
list variable that is part of net_buf struct.

d27cc52f37 iot/zoap: Add a helper to find an observer by address
In some situations, for example, when the remote side sends a RESET
message indicating that it is no longer interested in observing a
resource, it is helpful to have a way to obtain the obverser
representation.

ba026941a1 net: ipv6: Fix IPv6 prefix comparision
If the prefix length % 8 is not 0, then the remaining
bit length was calculated incorrectly and the prefixes
were claimed to match even though they might not be the
same.

Adding a test cases for testing this properly.

7b674cb287 net: linkaddr: introduce net_linkaddr_set function
The net_linkaddr_storage structure contains an array of bytes used
to store the link address.  This array can be different sizes
depending on the CONFIG options used when building.  To facilitate
consistency and error checking let's introduce a new helper function
to copy the addr and len values to this structure.

Also move all uses of memcpy related to net_link_storage structures to
the new helper function.

4aad767328 net: linkaddr: calculate linkaddr storage addr size via config
- Introduce NET_LINK_ADDR_MAX_LENGTH which is either 6 or 8
  depending on whether CONFIG_NET_L2_IEEE802154 is used
- Instead of being a placeholder single index array of uint8_t,
  let's use NET_LINK_ADDR_MAX_LENGTH to assign the size of the
  "addr" array field in the net_linkaddr_storage structure.
- Now that the "addr" field of net_linkaddr_storage contains the
  true size of the link address, we can remove "storage" field
  which was hard coded to 8 bytes (2 uint32_t's).
- Fix 2 references to the "storage" field of the net_linkaddr_storage
  structure.

ac74d8b652 license: Replace Apache boilerplate with SPDX tag
Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

645f867444 Bluetooth: Take advantage of IS_ENABLED macro for BT_DBG
The new IS_ENABLED macro allows exposing conditionally enabled code
always to the compiler, even though it may not ultimately end up being
built. This is in particular useful for letting the compiler catch any
logging format string errors. Introduce a new BT_DBG_ENABLED macro
that c-files need to define before including <bluetooth/log.h> in
order to choose whether BT_DBG() logs are enabled or not.

When no Bluetooth logs are enabled the patch also modifies the log
macros to have the format strings checked with the help of the
__printf_like annotation and empty static inline functions.

1adc58fd79 Bluetooth: Introduce a new connection parameter request callback
Introduce a new callback to bt_conn_cb that allows the application to
decide whether the accept or reject an incoming connection parameter
request. If the request is accepted the callback allows the
application to also adjust the values to what it thinks are more
appropriate.

The Zephyr Bluetooth API allows multiple registered connection
callbacks, so in principle there may be multiple le_param_req()
callbacks. It's recommended for an app to just use one (for clarity),
but if there are multiple the app is responsible for managing
potentially different requirements. In the case of multiple callbacks
each callback will receive the modified parameters in case a previous
callback modified them.

6f114e0a62 Bluetooth: Remove ACL details from BT_BUF_RX_SIZE
BT_BUF_RX_SIZE is used for the RX buffer pool which is used for both
ACL data and HCI events. It should therefore not contain any
ACL-specific details. This patch removes the ACL header size from the
macro and instead makes taking it into account the responsibility to
the Kconfig option. Since buffer sizes are anyway rounded up to the
nearest multiple of 4 the default goes up from 70 to 76.

30162aedf1 sensor: remove sensor value type
Remove the type field from the sensor value structure. All values will
have the type previously defined by SENSOR_VALUE_TYPE_INT_PLUS_MICRO.

This simplifies the interface, as apps will know what value type to
expect. Apps that prefer to use double values can optain them using the
sensor_value_to_double function.

e4e98f9d7b kernel: add user data API to timers
Similar to what was available with nano timers in the original kernel,
allow a user to associate opaque data with a timer.

Fix for ZEP-1558.

cd83e85edc arch: added support for the riscv32 architecture
RISC-V is an open-source instruction set architecture.
Added support for the 32bit version of RISC-V to Zephyr.

1) exceptions/interrupts/faults are handled at the architecture
   level via the __irq_wrapper handler. Context saving/restoring
   of registers can be handled at both architecture and SOC levels.
   If SOC-specific registers need to be saved, SOC level needs to
   provide __soc_save_context and __soc_restore_context functions
   that shall be accounted by the architecture level, when
   corresponding config variable RISCV_SOC_CONTEXT_SAVE is set.

2) As RISC-V architecture does not provide a clear ISA specification
   about interrupt handling, each RISC-V SOC handles it in its own
   way. Hence, at the architecture level, the __irq_wrapper handler
   expects the following functions to be provided by the SOC level:
   __soc_is_irq: to check if the exception is the result of an
                 interrupt or not.
   __soc_handle_irq: handle pending IRQ at SOC level (ex: clear
                     pending IRQ in SOC-specific IRQ register)

3) Thread/task scheduling, as well as IRQ offloading are handled via
   the RISC-V system call ("ecall"), which is also handled via the
   __irq_wrapper handler. The _Swap asm function just calls "ecall"
   to generate an exception.

4) As there is no conventional way of handling CPU power save in
   RISC-V, the default nano_cpu_idle and nano_cpu_atomic_idle
   functions just unlock interrupts and return to the caller, without
   issuing any CPU power saving instruction. Nonetheless, to allow
   SOC-level to implement proper CPU power save, nano_cpu_idle and
   nano_cpu_atomic_idle functions are defined as __weak
   at the architecture level.

96294b79a7 net: tcp: Signal EOF with a NULL buffer in the callback
TCP didn't actually have a way to signal synchronous receipt of a FIN
packet.  Extend the recv_cb API to allow a NULL buf argument with
status==0 (by analogy to Unix's zero-length read) to signal EOF.

Update docs too, and also echo_server which wasn't prepared to handle
this situation.

bits).  Currently, the net_context_set_state function is adding the

e2d3cc4b81 arm: Restructure ARM cpu related preprocessor conditionals.
The ARM code base provides for three mutually exclusive ARM
architecture related conditional compilation choices.  M0_M0PLUS,
M3_M4 and M7.  Throughout the code base we have conditional
compilation gated around these three choices.  Adjust the form of this
conditional compilation to adopt a uniform structure.  The uniform
structure always selects code based on the definition of an
appropriate config option rather the the absence of a definition.

Removing the extensive use of #else ensures that when support for
other ARM architecture versions is added we get hard compilation
failures rather than attempting to compile inappropriate code for the
added architecture with unexpected runtime consequences.

Adopting this uniform structure makes it straight forward to replace
the adhoc CPU_CORTEX_M3_M4 and CPU_CORTEX_M0_M0PLUS configuration
variables with ones that directly represent the actual underlying ARM
architectures we provide support for.  This change also paves the way
for folding adhoc conditional compilation related to CPU_CORTEX_M7
directly in support for ARMv7-M.

This change is mechanical in nature involving two transforms:

1)

  #if !defined(CONFIG_CPU_CORTEX_M0_M0PLUS)
  ...

is transformed to:

  #if defined(CONFIG_CPU_CORTEX_M0_M0PLUS)
  #elif defined(CONFIG_CPU_CORTEX_M3_M4) || defined(CONFIG_CPU_CORTEX_M7)
  ...

2)

  #if defined(CONFIG_CPU_CORTEX_M0_M0PLUS)
  ...
  #else
  ...
  #endif

is transformed to:

  #if defined(CONFIG_CPU_CORTEX_M0_M0PLUS)
  ...
  #elif defined(CONFIG_CPU_CORTEX_M3_M4) || defined(CONFIG_CPU_CORTEX_M7)
  ...
  #else
  #error Unknown ARM architecture
  #endif
