This change will make it easier to support the PAST feature, as

a8f47a1110 Bluetooth: host: Support fragmented L2CAP header
Fixes issue #26900.

A controller may fragment an L2CAP SDUs in any way it sees fit,
including fragmenting the L2CAP header. Likewise, the receiving
controller may send the fragmented header as ACL data to the host.

The Zephyr host assumed that a `BT_ACL_START` was at least 2 bytes long,
and consequently read the two-byte length field from the buffer without
length checks.

This commit allows the `BT_ACL_START` to be less than two bytes,
updating the `conn->rx_len` onces the `BT_ACL_CONT` with the remaining
part of the length field has been received.

76119c526e Bluetooth: GATT: Allow application to add subscription.
Allow the application to add subscription without resubscribing.
This is needed for persistent bonds that can go to deep sleep and
turn of the RAM or power-cycle.
In this case the application as a GATT client must have a way to add
the subscription callbacks back to the stack before the GATT server
sends notifications.
This should preferable be able to be done before even connecting
since the notifications can arrive immediately after connecting to
the peer.
The stack cannot persist this on it's own since it must remember the
function pointers for the callback functions. Storing these in
persistent storage would not be compatible with a Device Firmware
Upgrade (DFU) solution.

5b034e103f bluetooth: hci_driver: Add BT_QUIRK_NO_AUTO_DLE
Some controllers do not follow the recommendation of auto-initiating
a data length update if the host writes default data length parameters.

If the controller follows this recommendation, calling
LE Write Suggested Default Data Length command is sufficient
to ensure that the LL will auto-initiate the DLE procedure. Performing
a second procedure is unecessary.

In Core v5.2, Vol 4, Part E, Section 7.8.35:
The HCI_LE_Write_Suggested_Default_Data_Length command allows the
Host to specify its suggested values for the Controller's maximum
transmission number of payload octets and maximum packet
transmission time for packets containing LL Data PDUs to be used
for new connections. The Controller may use smaller or larger values
for connInitialMaxTxOctets and connInitialMaxTxTime based on local
information.

In short, this command sets connInitialMaxTxOctets
and connInitialMaxTxTime.

In Core v5.2, Vol 6, Part B, Section 4.5.10:

For a new connection: connMaxTxOctets shall be set to
connInitialMaxTxOctets and connMaxRxOctets shall be chosen by the
Controller. If either value is not 27 then the Controller should
initiate the Data Length Update Procedure at the earliest practical
opportunity.

4be66bd33d Bluetooth: Fix host RX thread deadlock
Fix host RX thread being deadlocked. The deadlock occurs because the
RX thread is stuck waiting in conn_tx_alloc with K_FOREVER but if the
connection is disconnected only the RX thread can unblock it in the
handling of the disconnect event.

This commit fixes this deadlock by splitting the processing of the
disconnected event into two parts.
The part needed to unblock the RX is to release resources held by
unack'ed TX packets and mark the connection state as not connected
anymore.
The RX thread waiting for free_tx fifo and the TX thread waiting for
the bt_dev.le.pkts semaphore will both check the connected state after
having acquired them and will abort if disconnected.
The rest of the processing will be handled at normal RX thread
priority like normal.

Move the bt_recv_prio handling to the Bluetooth host when the host
has defined its own RX thread (CONFIG_BT_RECV_IS_RX_THREAD=n).
If the HCI driver has the RX thread (CONFIG_BT_RECV_IS_RX_THREAD=y),
then the responsibility to call bt_recv and bt_recv_prio correctly
falls to the HCI driver.
The helper function bt_hci_evt_is_prio() is replaced with
bt_hci_evt_get_flags() so that the HCI driver can do this correctly.
This decision to replace was made so that existing HCI drivers
maintained out-of-tree will fail at compile time with the new system.

feature of the bluetooth host.

Deprecating the bt_conn_create_slave_le, and removing

has now been moved by to providing the peer direct address into the

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.

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.

commands are not supported. For combined builds or builds where the
capability of the controller is known it is not required to have runtime
check of controller extended advertising support.

This gives the following size reduction for hci_core.c:

Without legacy support
hci_core.c  19980     7.75%
total      257679

With legacy support
hci_core.c  21816     8.41%
total      259519

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.

80cb358fe2 Bluetooth: Kconfig: Fix BT_ECC defaults
The commit e85dd8af5d changed the way the BT_ECC Kconfig option
is enabled, however it got the dependency wrong. The dependency should
only look at BT_SMP_OOB_LEGACY_PAIR_ONLY if BT_SMP was also enable.

This broke e.g. the build of the mesh_demo app for the BBC
micro:bit since the memory consumption jumped up by roughly 2k.

This patch fixes the issue, and in the same go makes the Mesh handling
consistent by also using a conditional default rather than select.
