As per this link, under the heading of #VisitorAttacks we could see :

"*Visitor attacks* are prevented by giving guests and visitors temporary
and limited access to the network using a separate set of keys. These guest
keys have a limited lifetime."

How to implement guest key concept with #ZephyrBluetoothMesh ?

It's more of a provisioner issue than a Zephyr issue. On the Zephyr side
all you need to do is make sure your configuration allows at least two
network keys. Then you need to make your provisioner add the key to all
nodes, including the guest node, for the duration that you want the
guest to have access, and then go and remove the key from all nodes once
you want to revoke access (it doesn't matter if the guest is not around
anymore since no other node has that key). You'd probably also want to
do the same thing with the application key, i.e. use a separate one for
the guest (I think that's what's meant by "set of keys" instead of
talking about a single key).

Bluetooth: Mesh: Fix Node Identity advertising with PB-ADV

Do you have more details on this? Is there a bug with the patch, or
just
something else that needs to be tuned somewhere?

Johan

I think the patch exposes a problem with meshctl. Vikrant offers that
the SILABS App works fine and also uses GATT for provisioning and
configuration. Meshctl provisions fine, but hangs on discovery for
the
configuration service.

I think the problem is with meshctl's discovery filter. I'm not
familiar enough with the filter stuff to understand what's going on.

While meshctl is hanging on discovery, if I scan with bluetoothctl
and
connect to the node, the callback in meshctl fires and it does a get-
composition and proceeds normally.

That's all the detail I've got.

Steve

I added some instrumentation to parse_service_data and
parse_mesh_service_data.

The data type that gets passed to parse_mesh_service_data in data[0] is
0x00 while the function is expecting 0x01 (CONN_TYPE_IDENTITY), the
value of connection.type. That test fails and the function returns
false. No connection is made to the node.

Device property changed ServiceData
update_device_info called
parse_service_data target 00001827-0000-1000-8000-00805f9b34fb
parse_service_data failed

parse_service_data : parse_mesh_service_data

Does BT_MESH_NODE_IDENTITY_STOPPED get passed as the connection type?

Highlights
==========

This newsletter covers changes in Zephyr between these two
commits:

- 9bde3c06e ("tests: build_all: Add LPS22HB and LSM6DSL sensors build
test"), Apr 10 2018
- 4c400e876 ("net: ipv6: Fix crash from malformed fragment payload"),
Apr 17 2018

Important Changes
-----------------

Userspace calling convention change:

System calls from userspace on ARM targets now expect all
arguments to be passed via registers, instead of mixing stack and
registers as done previously.

DTS alias renames:

Various DTS aliases with underscores ('_') in their names were
renamed to use dash ('-') instead. Apparently, underscores were
technically always illegal to use in alias names. This change
avoids a dtc warning in newer versions. In-tree users were
updated; any out of tree applications using the old names will
need changes as well.

WiFi:

The initial outline for Zephyr's WiFi suport was
merged. Initial definitions were added in the following
areas:

- device driver skeleton in drivers/wifi
- a mostly stubbed out main header file, include/net/wifi.h
- WiFi network management in include/net/wifi_mgmt.h,
including definitions for events from so-called "offloaded"
devices (which are separate cores that implement WiFi
funcionality and communicate with the IC running Zephyr
via a higher-level protocol)
- shell support for controlling the network management API in
subsys/net/ip/l2/wifi_shell.c, which can be selected with
CONFIG_NET_L2_WIFI_SHELL. The initial commands are "wifi
connect", "wifi disconnect", and "wifi scan".

This is the groundwork for future changes completing the
generic framework and adding individual device drivers.

Device tree bindings for GPIO keys and LEDs:

Generic device tree bindings for GPIO-based buttons ("keys") and
LEDs were added in dts/bindings/gpio/gpio-keys.yaml and
dts/bindings/gpio/gpio-leds.yaml respectively.

The initial users are STM32-based boards, which now have device
tree nodes for their buttons and onboard LEDs defined.

Features
--------

Architectures:

ARM cores now flush the instruction pipeline after switching
privilege levels, to prevent execution of pre-fetched
instructions with the previous privilege.

Boards:

SoC support was added for the Cortex M4 core which is present in
the imx7d SoC. The Zephyr image must be loaded and run by an A7
core also present on the SoC. Initial board support was added for
the Colibri iMX7D as "colibri_imx7d_m4".

Sanitycheck now runs on hifive1.

96b_carbon_nrf51 now uses the new nRF SPIS driver.

Userspace mode was enabled by default for sam_e70_xplained.

Device tree:

Device tree bindings for STM32 GPIOs were defined, and all
STM32-based boards now have GPIO device nodes.

Drivers:

The native POSIX Ethernet driver now supports network statistics
collection, extending support for the Ethernet interface network
statistics framework that was recently merged.

The driver for the KW41Z BLE and 802.15.4 chip now supports the
OpenThread L2 layer, and received changes to its RNG source which
now feed its (slow and blocking) entropy source's output into the
Xoroshiro PRNG.

The nRF SPI drivers now appear to be completely supported. There
are three available drivers: spi_nrfx_spi.c is a master-only
driver for older devices (or devices with anomalies) without
direct memory access (DMA) support, spi_nrfx_spim.c is a master
driver for devices with DMA support, and spi_nrfx_spis.c is a
driver for the experimental SPI slave API which uses DMA.

Bug Fixes
---------

The k_malloc() and k_calloc() calls in the mempool implementation
now properly check for overflow in all configurations.

A pair of patches fixing IPv6 crashes were merged.

Following reports of confusion, the Windows installation guide
has been restructured to make it easier for new users to
understand what their choices are.

A few sample applications (BT's hci_usb, as well as USB's dfu and
wpanusb) now use the Kconfig knobs CONFIG_USB_DEVICE_VID and
CONFIG_USB_DEVICE_PID to configure the USB vendor and product
IDs. These knobs say they "MUST be configured by vendor"
(e.g. http://docs.zephyrproject.org/reference/kconfig/CONFIG_USB_DEVICE_VID.html);
they default to 0x2FE3 and 0x100 respectively. The VID 0x2FE3
doesn't appear to be allocated by the USB-IF.

The wpanusb sample and ENC28J60 Ethernet driver received fix-ups,
and, in the ENC28J60 case, optimizations.

The number of interrupts on the nRF52840 SoC was fixed.

PWM was disabled on nucleo_f103rb, fixing some test build breaks
and continuing Zephyr's move towards a consistent set of default
board configurations.

CONFIG_CUSTOM_LINKER_SCRIPT, which allows the user to override
the linker scripts provided by Zephyr itself, was fixed. This had
been broken since the transition to CMake, so it seems to have
few, if any, active users.

The Atmel SAM0 flash driver's build is fixed when
CONFIG_FLASH_PAGE_LAYOUT is disabled.

A concurrency fix to the SPI driver core was merged.

I looked at this too. Provisioning seems to complete, but the proxy

discovery to succeed.

While this is happening, if I use bluetoothctl to scan and then
connect
to the node, the callback in meshctl fires and it starts up and
functions as expected. It appears that something is amiss with the
discovery filter.

I believe that the SILABS App uses advertising bearer for
provisioning,
so it's not conclusive that it working and meshctl failing is
definitely a Bluez issue. I checkout an early March version of Bluez
and Zephyr. The problem is still there.

Hi Vikrant,

Thanks for this pointer! I was wondering the same thing, the docs for
the other mesh apps
(http://docs.zephyrproject.org/samples/bluetooth/mesh/README.html and
http://docs.zephyrproject.org/samples/bluetooth/mesh_demo/README.html)
are a bit thin on the step-by-steps. I had no idea there was a
board-specific app with more detailed docs.

Thanks,

Hi

I am looking for a network offload (CONFIG_NET_OFFLOAD) sample application.
I want to integrate a connectivity module (e.g. running zephyr's openthread stack as NCP - network control processor) with an apps mcu running zephyr with CONFIG_NET_OFFLOAD.

My questions:

1. Is the network offload feature designed to ultimately target integration of NCP?

2. The openthread supports spinnel protocol between host MCU and NCP. Why we don't have spinnel implementation in zephyr?
I see that spinnel IETF draft has expired. Is it not the plan to standardize the interface between apps mcu and connectivity module?

Regards

Vakul

Hi guys,

is it possible to use the Nordic DFU feature in conjunction to Zephyr. I need to upgrade the nodes of a BT mesh network and it would be amazing if I could.

If it isn't, is there any alternative to that?

Thank you. Best regards,

Rodrigo Peixoto. Ayna - [Embedded systems design house]

Fixing the mailing lists; sorry!

Hello Zephyr community!

This is the first of a periodic (weekly-ish) newsletter tracking the latest
Zephyr development.

The goals are to give a human-readable summary of what's been merged
into master, breaking it down as follows:

- Highlights: important changes, new features, and bug fixes
- Individual changes: a complete list of patches, sorted chronologically
and sorted into separate areas (like "Architectures", "Kernel", "Drivers",
etc.)

The "important changes" will include things like API breaks and some
significant features. The focus is on changes in Zephyr that are
likely to require
changes in your Zephyr applications.

The new features and bug fixes sections aren't meant to be exhaustive; the
idea is to cover what happened from a high level. You can check the individual
changes section for a complete list of commits in areas you're interested in.

Any and all feedback on mistakes, significant omissions, etc., is welcome. We
will do our best to get things right, but we'll mess up sometimes :).

To start, I'm going to send these as plain text. Any comments on that or other
formatting and style feedback is also welcome.

Cheers,
Marti and Open Source Foundries

Highlights
==========

This newsletter covers changes in Zephyr between these two
commits:

- 4291fb67a ("usb: Remove duplicated CDC_ECM_SUBCLASS
definition"), Apr 4 2018

- 9bde3c06e ("tests: build_all: Add LPS22HB and LSM6DSL sensors
build test"), Apr 10 2018

The most significant of these changes are due to a large re-work
of the SPI APIs, which affected both the peripheral drivers
themselves as well as their users.

Important Changes
-----------------

SPI API
~~~~~~~

The SPI API (in include/spi.h) has been re-worked and
finalized. All in-tree users were upgraded to the new API. The
old SPI API, and all of its implementations, have been
removed. Out of tree uses of the old SPI API will need updates. A
summary of the API changes follows.

The I/O APIs now use a new struct spi_buf_set, which contains a
pointer to a struct spi_buf array, and its length:

struct spi_buf_set {
const struct spi_buf *buffers;
size_t count;
};

This structure is used in the I/O APIs so that the TX and RX
arguments can be specified in two formal parameters, which allows
using registers instead of the stack in some API calls.

All SPI API calls also now take a pointer to the SPI device
itself as their first parameter, instead of storing that device
in struct spi_config. This makes the SPI API consistent with
other Zephyr device APIs.

The "EEPROM mode" support was removed from the master controller
operations bit mask. It was replaced with a new flag,
SPI_CS_ACTIVE_HIGH, which inverts the usual polarity of the chip
select pin.

The spi_config parameter passed to the SPI API is now constant,
allowing it to be stored in flash memory.

The asynchronous SPI API no longer uses CONFIG_POLL
directly. Instead, a layer of indirection through
CONFIG_SPI_ASYNC was introduced, which selects CONFIG_POLL.

In addition to these changes in the SPI master mode API,
experimental support for SPI slave implementations was added to
the new API.

Board Porting Guidelines
~~~~~~~~~~~~~~~~~~~~~~~~

Official board porting guidelines were merged, which have
consistent rules for how to structure a board's Kconfig. For
details, refer here:

http://docs.zephyrproject.org/porting/board_porting.html#default-board-configuration

Features
--------

VLAN support:

VLAN support was added for Ethernet network
interfaces. Initial support is provided for for mcux, native
POSIX, and Atmel E70. The SLIP driver also has VLAN support.

New net shell commands "net vlan", "net vlan add", and "net
vlan del" were added to query and manipulate the VLAN
configuration.

A new sample application, samples/net/vlan, was added, which
can be used to set VLAN tags for ethernet interfaces.

As part of these and other network changes, the ethernet
files now live in their own directory, net/ip/l2/ethernet.

Red/black trees:

A new red/black balanced binary tree implementation was
added; the API is available in include/misc/rb.h. Like the
linked list types, the structure is *intrusive*: red-black
tree nodes are meant to be embedded in another structure,
which contains the user data associated with that node. Code
size compared to a doubly linked list on most architectures
is approximately an additional 2-2.5 KB.

Completion of DTS support for I2C and SPI on STM32:

All STM32-based boards now use device tree for I2C and SPI
peripherals.

Bluetooth generalizations:

Continuing the effort to generalize the core Bluetooth
subsystem across SoCs, the Bluetooth "ticker" timing API now
includes a generic hal/ticker.h file, which abstracts out SoC
specific definitions.

Drivers:

Ethernet is now enabled by default on the sam_e70_xplained
board.

New driver support includes SPI on nRF52, an interrupt in
transfer callback on USB HID, USB CDC EEM support for
encapsulating Ethernet packets over a USB transport, and GPIO
triggering for the ST LSM6DSL accelerometer and IMU.

Boards:

New boards include the SiFive HiFive1 and Nordic nRF52
Thingy:52 (PCA20020).

Speeding up CI:

An effort is underway to reduce the amount of time spent in
CI. To that end, an additional CI build slave was added, some
duplicative test coverage on qemu_x86 and qemu_cortex_m32 was
eliminated, and other optimizations were performed.

Boot banner changes:

The boot banner now prints the git version (based on git
describe) and hash, but timestamps were removed from it by
default to increase the reproducibility of Zephyr builds.

User mode memory pools:

A new memory pool implementation which is compatible with use
from user mode threads was merged; the API is available in
include/misc/mempool.h. This implementation shares code with
the in-kernel k_mem_pool API, but avoids constraints that are
incompatible with user mode. Memory pools are defined at
compile time with SYS_MEM_POOL_DEFINE(), and initialized by
sys_mem_pool_init(). Memory may be allocated and freed from
an initialized memory pool with sys_mem_pool_alloc() and
sys_mem_pool_free(), respectively.

Network interface management:

Interface statistics collection is now per-interface.

The network shell command "net iface" can now enable or
disable network interfaces by index.

Initial support for ethernet interface configuration has been
merged. This includes a link speed capabilities query. An API
was also merged for changing hardware configuration; this
includes link speed, but is not limited to it.

Bug Fixes
---------

Support for enabling GPIO port H on STM32L0 was fixed.

Support accessing sub-region attributes on ARM MPUs was fixed.

A pair of Bluetooth mesh fixes were merged, including a null
dereference and an issue related to enabling node identity
advertising.

The behavior of the CONFIG_FP_SOFTABI option was fixed. It now
generates floating point instructions, rather than turning them
off, which it was doing previously.

The temperature sensor channel for the nRF TEMP IP block was
fixed; it is now SENSOR_CHAN_DIE_TEMP.

A fix was merged for k_thread_create(), which now properly checks
the provided stack size on systems which enforce power of two
sizes.

POSIX fixes for pthread_cancel and timer_gettime were merged.

Dozens of commits cleaning up and fixing the test cases were
merged.

But after adding support for LOW POWER feature got RAM overflow again…

Could you review the use of RADIO_LL_LENGTH_OCTETS_RX_MAX, just a suspicion that its incorrectly used on nRF51, if so, you could be saving few hundred bytes.

Do feel free to send a PR if you fix something.

Hi Antonio,

Please take a look at this mail chain: https://lists.zephyrproject.org/g/devel/topic/16760883#1960

a BBC micro:bit with nRF51822 256KB flash and 16 KB RAM can support BLE mesh. Yes, it is stretch on a 16 KB RAM variant, but you can take a look at the output of “make rom_report” to fine tune/reduce RAM usages in your application.

Since GATT (GATT_PROXY,PB_GATT,Peripherial) support is so memory hungry, can we use PB_ADV instead and do something like
remote provisioning ?

https://infocenter.nordicsemi.com/index.jsp?topic=/com.nordic.infocenter.meshsdk.v0.9.1/md_examples_pb_remote_server_README.html

Is this feature supported ?
Trying to make something useful out of the NRF51, like a simple low power node mesh device.
But seems they are good only as a beacons for now ;(
Or perhaps someone can recommend the way to provision NRF51 node over the PB_ADV barrier ?
