578dbe1c0a Bluetooth: Mesh: Support reliable sending when publishing
Until now the choice of reliable sending (segmented messages with
acks) was implicitly dependent on the size of the payload. Add a new
member to the bt_mesh_model_pub to force using segment acks even when
the payload would fit a single unsegmented message.

Refactor the handling of network nodes and their keys into a separate
Mesh Configuration Database (CDB). This, not only creates a separation
of the local node and the other nodes, but also makes it possible to
implement functions to manage the whole, or at least parts of the mesh

Replaces the Mesh model settings_commit callback with a start callback,
indicating that the mesh model behavior is ready to start. Everything
that was previously done in the settings_commit callback may be moved to
this callback, which gets called just after mesh settings are committed,
instead of in the middle of the process.

This resolves an issue where models had no context in which to start
their behavior, as the previous settings_commit call fired before the
mesh was declared valid, making access APIs inaccessible.

2802fa4e6d treewide: avoid address-of-compound-literal idiom in headers
In C99 the construct (T){init-list} is called a compound literal, and
is an lvalue.  In C++ it is simply a cast expression to non-rvalue
type, which is a prvalue.  In both languages the expression is a
temporary, but in C99 taking its address is well-defined while in C++
it is an error diagnosed as "taking address of temporary".

Headers that may be used in C++ application code must avoid invalid
expressions.  Replace all uses of &(T){init-list} in headers with the
functionally equivalent but C++-legal (T[]){{init-list}}.

which enable Tx power read/write operations within BLE radio events
on a per role/connection basis.

The functionality is enabled upon the Kconfig advanced configuration
triggered by

- BT_CTLR_TX_PWR_DYNAMIC_CONTROL

depending on the enablement of Zephyr HCI vendor-specific command
extensions.

Necessary low-level radio HAL functionality and power definitions
are also supplied to address the high-level functionality of

2d859cc147 Bluetooth: Mesh: Make model publication struct more compact
commit 42d330406e introduced the FastPeriodDivisor value to
to the model publication struct. Based on the way it was grouped it
seems the intention was to fit it within the same octet as other bit
fields, but it actually makes the octet overflow by one bit. This ends
up creating another u8_t variable which in turn adds 24 bits of
padding after it.

To keep the size of the struct as compact as possible, group the flag
together with the key index, since that only requires 12 bits. Some
care is needed here, since the mesh stack does have special internal
key index values that require more than 12 bits such as
BT_MESH_KEY_UNUSED and BT_MESH_KEY_DEV. In this case restricting
ourselves to 12 bits is fine since the value in the model publication
struct follows 1:1 the value received in the Config Model Publication
Set message, and there the parameter is defined to be exactly 12 bits.

0a925bdf9c Bluetooth: L2CAP: Process fixed channels in the RX thread
Now that the TX path and TX context (bt_conn_tx) has been redesigned
to free the contexts always in the system workqueue, it means the
system workqueue is the only context where their allocation may also
fail. This is particularly problematic with us having all L2CAP
channels (fixed & CoC alike) deferred to the system workqueue. It is
especially bad for fixed channels where being able to send responses
for SM, L2CAP signaling and ATT is critical to avoid timeouts for the
connection.

This patch moves the processing of all fixed L2CAP channels back to
the RX thread, thereby making it possible (and safe) to block while
waiting for a TX context to become available.

interface may have its own buffer headroom requirements. Currently the

maximum of the HCI driver and HCI raw headroom requirements for the

0151d6dc33 Bluetooth: Mesh: Model extension concept
Adds the model extension concept to the access layer, as described in
the Mesh Profile Specification, Section 2.3.6. Extensions are
implemented as a tree, using two pointers in each model:

The extends pointer points to the first extended model, and the next
pointer points to the next sibling or (if the NEXT_IS_PARENT flag is
set) the parent model in the tree, forming a cyclical "Left-child
right-sibling" (LCRS) tree. The tree root can be obtained by calling
bt_mesh_model_root_get(), and the extended models can be walked by
calling bt_mesh_model_tree_walk().

According to the Mesh Profile Specification Section 4.2.3, all models in
the same extension tree share one subscription list per element. This is
implemented by walking the model's extension tree, and pooling the
subscription lists of all models in the same element into one. If the
config server adds a subscription to a model, it may be stored in any of
the model tree's models' subscription lists. No two models in the same
extension tree and element will have duplicate groups listed. This
allows us to increase extended models' capacity for subscriptions
significantly.

Many messages in the provisioning protocol are the same for provisioner

This introduces to concept of local and remote device keys. The models

the send and receive path in the transport layer have been updated to
support encrypting/decrypting with local and remote device keys.

When a node has been provisioned it is stored in bt_mesh_net.nodes. If
CONFIG_BT_SETTINGS is enabled, they are also saved to settings. If the
callback node_added in bt_mesh_prov has been set, it will be called for
every node that gets provisioned. This includes when they are retrieved
from settings.

can be provisioned.

BLUETOOTH CORE SPECIFICATION Version 5.1 | Vol 3, Part G page 2360:

   Authentication and authorization may be required by the server to
   write the configuration descriptor.'

In addition to that also ensure that notification are not re-enabled
until the proper security level is reached to conform to the following
statement:

  '10.3.1.1 Handling of GATT indications and notifications

   A client “requests” a server to send indications and notifications
   by appropriately configuring the server via a Client Characteristic
   Configuration Descriptor. Since the configuration is persistent
   across a disconnection and reconnection, security requirements must
   be checked against the configuration upon a reconnection before
   sending indications or notifications. When a server reconnects to a
   client to send an indication or notification for which security is
   required, the server shall initiate or request encryption with the
   client prior to sending an indication or notification. If the client
   does not have an LTK indicating that the client has lost the bond,
   enabling encryption will fail.'

b763a9be3a Bluetooth: Host: Fix checking for sufficient encryption key size
A security vulnerability in the Bluetooth BR/EDR Bluetooth Core
specification versions 1.0 through 5.1 has been identified as
CVE-2019-9506. The Bluetooth BR/EDR encryption key negotiation
protocol is vulnerable to packet injection that could allow an
unauthenticated user to decrease the size of the entropy of the
encryption key, potentially causing information disclosure and/or
escalation of privileges via adjacent access. There is not currently
any knowledge of this being exploited.

From Core spec erratum 11838:

A device shall enforce an encryption key with at least 128-bit
equivalent strength for all services that require Security Mode 4,
Level 4. For all other services that require encryption, a device
should enforce an encryption key with at least 56-bit equivalent
strength, irrespective of whether the remote device supports Secure
Simple Pairing.

After encryption has been enabled, the Host should check the
encryption key size using either the HCI_Read_Encryption_Key_Size
command (see [Vol 2] Part E, Section 7.5.7) or a vendor-specific
method.

4396dc9c71 Bluetooth: Simplify bt_gatt_notify_cb() API
This API had several issues:

 - The parameter types and order were inconsistent with e.g.
   bt_le_adv_start()
 - There were no real users of num_params, which just caused increased
   code size and memory consumption for no good reason.
 - The error handling policy was arbitrary: if one of the
   notifications would fail it would be impossible for the caller to
   know if some notifications succeeded, i.e. at what point the
   failure happened. Some callers might also want to make note of the
   failure but continue trying to notify for the remaining parameters.

The first issue is easily fixable, but because of the other two I
think it's best we don't have this code as part of the stack, rather
require whoever needs it to do the for loop themselves. It's just a
few lines of code, so the benefit of having this in the stack was
anyway quite minimal.

The commit 8d0ef1eb85 attempted to fix
test case MESH/SR/HM/CFS/BV-02-C, however inadvertently ended up
introducing a hidden bug. This bug was unearthed thanks to commit
686f5c79cf. We have to keep always track
of the FastPeriodDivisor state whether we're using it (faults > 0) or
not (faults == 0). Introduce a boolean field to the model publication
that's used to indicate whether the FastPeriodDivisor should be
applied or not, instead of zeroing the divisor when there are no
faults (this would cause wrong behavior when faults appear again).

Additionally, the PTS seems to require that we wait until the end of
the existing period before sending the next Health Current Status,
rather than sending it immediately when the fault count changes.

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

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

This change makes the internal bt_conn mapping function accessible to
applications in conn.h. The function name is changed to

Fix this issue, but do it by simplifying the (re)transmission state

f7a1ffe614 Bluetooth: GATT: Change attribute count from u16_t to size_t
The change changes the type of the attribute count in the
bt_gatt_service struct to size_t.

The background for the change is that with this variable being a
u16_t, we assign something that has been cast to an unsigned long
(from "ARRAY_SIZE") to an u16_t variable, and that Lint complains
about a loss of information (27 bits to 16 bits in the case I found).

(The issue seems to be not only about the cast, but about what is
casted. I suspect that Lint may be confused by the magic of
ZERO_OR_COMPILE_ERROR.)

df4220b213 Bluetooth: L2CAP: Add support for dynamically allocated PSM values
The Bluetooth core specification splits the valid LE L2CAP PSM range
into two subranges:

 - Standard, SIG-assigned fixed PSM values in the range 0x0001-0x007f
 - Dynamic, allocated at runtime in the range 0x0080-0x00ff

Previously the bt_l2cap_server_register() API was assuming that the
app would always decide the PSM, which effectively made it impossible
to have collision-free dynamic PSMs. This patch extends the
implementation so that if server->psm is 0, then the stack will look
for a free PSM from the dynamic range and take it into use.

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.
