48689343dc Bluetooth: Simplify le_adv_update() function
Closes #94549
Removed vestigial d and d_len variables from le_adv_update()
and replaced them with a single bt_ad wrapper. This simplifies
the function while maintaining identical functionality.

bcdd74d815 bluetooth: host: gatt: destroy key after hash calc completes
To generate the GATT Database Hash characteristic, the function
`db_hash_setup` is called. It allocates an entry for the AES key that will
be used in the CMAC calculation. Next, `db_hash_update` is called to feed
all GATT database entries into the hash. Finally, `db_hash_finish`
produces the resulting hash.

However, the AES key entry allocated in `db_hash_setup` was not being
destroyed after the hash generation completed. This caused a memory
leak, eventually leading to the error `PSA_ERROR_INSUFFICIENT_MEMORY`
(`-134`).

This commit fixes the issue by destroying the allocated AES key after
the GATT Database Hash calculation is complete, by calling
`psa_destroy_key` in `db_hash_finish`.

31a3315d61 Bluetooth: BAP: Replace bt_bap_iso with bt_iso_chan for streams
Modify the struct bt_bap_stream to have a direct reference to the
bt_iso_chan, rather than having a reference to the parent
bt_bap_iso.

This change will allow users to more easily and directly access
the bt_iso_chan, instead of getting the reference via
bt_bap_ep_get_info.
Additionally, this allows users to access the bt_iso_chan for
streams that are not codec configured, and thus not have a
bt_bap_ep reference.

818e18eacb bluetooth: host: Use critical section when making channel ready to send
A public API call that sends ACL data — for example, `bt_gatt_notify` —
can be invoked from a preemptive thread context. This API, in turn,
calls the `raise_data_ready` function, which adds an L2CAP channel to
the `l2cap_data_ready` list.

The atomic variable used to create a critical section around
`l2cap_data_ready` did not work, because a preemptive thread can be
pre-empted at any time. This means that regardless of the `atomic_set`
result, we cannot trust it — the thread could be preempted after the
call, and the atomic variable state could be changed (specifically by
the TX processor in this case). The same issue applies to
`bt_conn_data_ready`, which is called next.

When making an L2CAP channel ready for sending data, we need to use a
critical section when appending a channel to the `l2cap_data_ready`
list. The same applies to the `conn_ready` list.

Since cooperative threads can only be rescheduled explicitly, we must
ensure there are no rescheduling points when accessing either the
`l2cap_data_ready` or `conn_ready` lists.

For `l2cap_data_ready`, this occurs in `get_ready_chan`, which is called
from `l2cap_data_pull`, which in turn is called by the TX processor. For
`conn_ready`, it occurs in `get_conn_ready`, which is also called from
the TX processor. Both functions have no rescheduling points when
working with their respective lists, so they do not require a critical
section.

This change removes the atomic variables previously used to create a
critical section for both lists, as they were ineffective. Instead,
`k_sched_lock`/`k_sched_unlock` are used where code may be executed from
a preemptive thread context. The `sys_slist_find` function is used to
check whether a channel or connection is already in the corresponding
list.

Fixes #89705

2df8578c7a Bluetooth: Classic: SDP: Improve SDP discovery response
In current implementation, the attribute of the registered SDP record
will not be included in responding packet if the attribute data length
is more than the MAX payload size(`MIN(SDP_MTU, sad->sdp->chan.tx.mtu)
- sizeof(struct bt_sdp_hdr)`). And it causes the failure of ssa or sa
discovery.

Improve the SDP server to support the case by extending the
continuation state length. A 4 bytes space is extended to store the
attribute offset.

In this way, the attribute can be transmitted in segments according
to the reaming space of the responding buffer.

9e5e23d1e9 bluetooth: host: hci_core: prioritize LE Conn Complete event handling
During debugging multiple.sh test, a race condition was observed where
advertiser state on Host and Controler was desynchronized.

Below is the sequence of actions led to this issue:

0. Host has queued few priority events at this moment.
1. Controller establishes a connection and stops the advertiser.
2. Controller sends to Host BT_HCI_EVT_LE_ENH_CONN_COMPLETE.
3. Host deprioritizes BT_HCI_EVT_LE_ENH_CONN_COMPLETE event and doesn't
   process it immediately.
4. Controller sends to Host other priority events which are processed
   immediately.
5. Host wants to disable the advertiser in order to update the Resolving
   List (see `bt_id_add`).
6. Host sends to Controller BT_HCI_OP_LE_SET_ADV_ENABLE(Disable)
   command.
7. Controller sends to Host BT_HCI_EVT_CMD_COMPLETE event on
   BT_HCI_OP_LE_SET_ADV_ENABLE command.
8. Host prioritizes this BT_HCI_EVT_CMD_COMPLETE event, processes it
   immediately and clears `BT_ADV_ENABLED` flag for the advertiser.
   Note that Controller already has the advertiser disabled after
   establishing connection on step 1.
9. Host sends few commands in a row and Controller sends
   BT_HCI_EVT_CMD_COMPLETE events that are prioritized (see
   `bt_id_add`).
10. Host wants to re-enable the advertiser after updating the Resolving
    List.
11. Host sends to Controller BT_HCI_OP_LE_SET_ADV_ENABLE(Enable)
    command.
12. Controller sends to Host BT_HCI_EVT_CMD_COMPLETE event on
    BT_HCI_OP_LE_SET_ADV_ENABLE.
13. Host prioritizes this BT_HCI_EVT_CMD_COMPLETE, processes it
    immediately and sets `BT_ADV_ENABLED` flag for the advertiser.
14. Controller has the advertiser enabled.
15. Host now processes the delayed BT_HCI_EVT_LE_ENH_CONN_COMPLETE
    event.
16. Host resets the advertiser state, thinking the Controller's
    advertiser is also stopped.

This commit prioritizes LE Connection Complete and LE Enhanced
Connection Complete events to drop advertiser state on Host immediately
once the corresponding event was received.

27e4533038 bluetooth: tbs: fix issues for setting URI scheme for GTBS
- "bt_tbs_set_uri_scheme_list()" function does not setting URI for
 GTBS instance. Using "inst_lookup_index()" fixes issue to find
 registered GTBS instance for provided bearer_index.
- "bt_tbs_set_uri_scheme_list()" function overrides URI scheme list
 with latest provided list. But the expectation is that it should
 keep previously added URI schemes and only update new scheme which
 are not part existing list. Code is updated to fix this.
- The same function uses net-buf to combine all URI schems for all
 TBS bearer if current request is not for GTBS instance. Currently,
 the code only uses combined URI scheme list for logging purpose and
 it is not used to send for URI Scheme notification to provide
 updated GTBS URI scheme to remote. Code is now updated to add
 dynamic buffer to add all TBS URI scheme list for GTBS instance
 and notify it similar to other functions to optimise memory usage.

stack is depended on the upper layer, the thread stack needs to set by

consumption is the product of the added value and the number of DLCs.
