Joakim Andersson 0d9db89dde Bluetooth: host: Fix compilation issue for extended advertising beacon
Fix compilation issue for extended advertising beacon. Adv pool was
mistakenly put under BT_OBSERVER define.
Both observer and broadcaster use the bt_lookup_id_addr. SMP cannot
be enabled without connections, so for broadcaster and observer there
will not be a lookup.
Fix compilation warning for extended scanner-only build.

Joakim Andersson 203d13c1a4 Bluetooth: host: Handle zero-set local RPA in enhanced conn complete
According to the BT Core spec. The local RPA field in the enhanced
connection complete event should be set if the own-address type was
set to 0x02/0x03 and the controller generated an RPA using a non-zero
IRK, otherwise the controller should return all zeroes.
In the case where we generate the RPA in the host instead we need to
handle set the on-air RPA address based on the random address set by
the host.
If this is not handled then pairing will fail because the on-air
addresses are used as input to the pairing procedure.

Joakim Andersson d4f22a8216 Bluetooth: host: Add support for multiple advertising set
Add support for multiple advertising set. Move the advertising state
flags to be per advertising set and loop over advertising sets instead
of looking up legacy advertiser set or handle 0.

Since it is not certain that the advertising set terminated event can
arrive directly after the connection complete event there is currently
a limitation that there can only be one local identity used by
connectable advertisers at a time. This guarantees that we know
the local identity being used in the connection complete event.

Joakim Andersson 18bee9178f Bluetooth: host: Add non-connectable directed advertising support
This patch introduces two major changes to the directed advertising
feature of the bluetooth host.

Deprecating the bt_conn_create_slave_le, and removing
bt_conn_le_create_slave which has never been released. This behaviour
has now been moved by to providing the peer direct address into the
advertising parameters.

Introducing directed advertising support for nonconnectable
directed extended advertising, both scannable and non-scannable.

A bug was also fixed in the the directed-adv command in the shell
when the argument "low" was given. The advertiseng parameter pointer
declared with BT_LE_ADV_CONN_DIR_LOW_DUTY was declared in a scope that
was no longer valid when it was used to start the advertiser.

Joakim Andersson 19434a1056 Bluetooth: host: Do not set adv random address before adv parameters
The LE Set Extended Advertising Set Random Address command may be
issued at any time after an advertising set identified by
the Advertising Handle parameter has been created using the
LE Set Extended Advertising Parameters command.

This commit fixes the advertising set issueing the set random address
command before the advertising set is created in the controller.
Since the le_adv_set_random_addr function has is used to get the the
own address parameter for the it could not simply be moved, and
moving the own address parameter handling out of this function
would create a potentioal maintaince problem.
Also this function is used for both with and without advertising
extension feature so changing it is not trivial without breaking all
the previous random address handling already put in place.
The simplest solution was therefore to postpone the command until the
parameters has been set using 2 flags.

Dan Erichsen 6a12a2dbe1 bluetooth: host: Do not send unwanted SC indicate
Fixes #23485

When we create a GATT table dynamically, we also create a hash
identifying this table. This hash can be stored in persistent memory and
we can thus determine after recreating the GATT table whether the
services have changed or not from before the reboot.

When these hashes are identical, it implies that the table has not
changed, wherefore a service changed indication should not be sent to
any bonded clients. The method for achieving this was to remove the
gatt_sc.work entry from the work queue. This work queue entry was to
send an indication to the clients when the table had been allocated.
If the final entry then caused the hashes to match, the indication
would be cancelled.

On unit testing this behaviour in simulation and in practice, we found
that the indication was sent nonetheless, and the issue was located to
be tied to the SERVICE_RANGE_CHANGED flag which is set when the services
are changed and is cleared when the indications are being sent out.

It was the job of the work queue entry to clear this flag, and as the
entry was never serviced, the flag was never cleared, and when
sc_commit() is called at the end of the process, it believes that there
is a new service change pending and therefore starts the job over, thus
creating a redundant indication to the clients.

This commit fixes the issue by clearing the flag when the work entry
is removed due to a hash match. This has been unittested in a live
environment, in a simulation environment, and sanitycheck has been run
on it.

use this RPA address for the next RPA timeout period.

The central role always refreshes the RPA address for the initiator,
this will make the OOB information not usable as the peer cannot
recognize the central role since the RPA address is changed.
Check if the initiator can use the address for the duration of the of
remaining RPA period.

address. The central role should only use the default identity.

Fix issue where an invalid (all zeroes) hash was written to settings
storage on reset. This caused the old value to written to zeroes, before
being written back to it's original value again immediately after.
This causes excessive flash wear.

This happens because the check if (k_delayed_work_remaining) returns the
amount of time until the work will execute. When that time has run out
the time is zero, but the work has not yet been executed.
We then write the invalid hash to flash, and then once the work-item

Ulf Magnusson eddd98f811 kconfig: Replace some single-symbol 'if's with 'depends on'
I think people might be reading differences into 'if' and 'depends on'
that aren't there, like maybe 'if' being needed to "hide" a symbol,
while 'depends on' just adds a dependency.

There are no differences between 'if' and 'depends on'. 'if' is just a
shorthand for 'depends on'. They work the same when it comes to creating
implicit menus too.

The way symbols get "hidden" is through their dependencies not being
satisfied ('if'/'depends on' get copied up as a dependency on the
prompt).

Since 'if' and 'depends on' are the same, an 'if' with just a single
symbol in it can be replaced with a 'depends on'. IMO, it's best to
avoid 'if' there as a style choice too, because it confuses people into
thinking there's deep Kconfig magic going on that requires 'if'.

Going for 'depends on' can also remove some nested 'if's, which
generates nicer symbol information and docs, because nested 'if's really
are so simple/dumb that they just add the dependencies from both 'if's
to all symbols within.

Replace a bunch of single-symbol 'if's with 'depends on' to despam the
Kconfig files a bit and make it clearer how things work. Also do some
other minor related dependency refactoring.

The replacement isn't complete. Will fix up the rest later. Splitting it
a bit to make it more manageable.

(Everything above is true for choices, menus, and comments as well.)

Detected by tweaking the Kconfiglib parsing code. It's impossible to
detect after parsing, because 'if' turns into 'depends on'.

Andrew Boie efc5fe07a2 kernel: overhaul unused stack measurement
The existing stack_analyze APIs had some problems:

1. Not properly namespaced
2. Accepted the stack object as a parameter, yet the stack object
   does not contain the necessary information to get the associated
   buffer region, the thread object is needed for this
3. Caused a crash on certain platforms that do not allow inspection
   of unused stack space for the currently running thread
4. No user mode access
5. Separately passed in thread name

We deprecate these functions and add a new API
k_thread_stack_space_get() which addresses all of these issues.

A helper API log_stack_usage() also added which resembles
STACK_ANALYZE() in functionality.

Enabling this option will make the master role not require the

When privacy is disabled by default the scanner still protects it's

address for the passive scanner unless the Kconfig option to scan with
the identity has been enabled.

This makes passive scanner behave the same way as an active scanner
since none of them will report directed advertising reports towards
the scanners identity.

This also enables the advertiser to switch out the random address which
is needed for the Bluetooth Mesh LPN case.
