Bluetooth: HCI: Add support for LL Extended Feature Set

2025-12-01T21:21:16+00:00

This adds support for emulating LL Extended Feature Set introduced in 6.0 that adds the following: Commands: - HCI_LE_Read_All_Local_Supported_Features(0x2087)(Feature:47,1) - HCI_LE_Read_All_Remote_Features(0x2088)(Feature:47,2) Events: - HCI_LE_Read_All_Remote_Features_Complete(0x2b)(Mask bit:42) Signed-off-by: Luiz Augusto von Dentz

Bluetooth: ISO: Add support to bind to trigger PAST

2025-12-01T21:00:04+00:00

This makes it possible to bind to a different destination address after being connected (BT_CONNECTED, BT_CONNECT2) which then triggers PAST Sender proceedure to transfer the PA Sync to the destination address. Signed-off-by: Luiz Augusto von Dentz

Bluetooth: hci_sync: fix set_local_name race condition

2025-08-22T17:57:31+00:00

Function set_name_sync() uses hdev->dev_name field to send HCI_OP_WRITE_LOCAL_NAME command, but copying from data to hdev->dev_name is called after mgmt cmd was queued, so it is possible that function set_name_sync() will read old name value. This change adds name as a parameter for function hci_update_name_sync() to avoid race condition.

Bluetooth: ISO: Fix not using bc_sid as advertisement SID

2025-06-11T20:29:55+00:00

Currently bc_sid is being ignore when acting as Broadcast Source role, so this fix it by passing the bc_sid and then use it when programming the PA: < HCI Command: LE Set Exte..

Bluetooth: hci_conn: Fix not setting timeout for BIG Create Sync

2025-04-25T19:03:19+00:00

BIG Create Sync requires the command to just generates a status so this makes use of __hci_cmd_sync_status_sk to wait for HCI_EVT_LE_BIG_SYNC_ESTABLISHED, also because of this chance it is not longer necessary to use a custom method to serialize the process of creating the BIG sync since the cmd_work_sync itself ensures only one command would be pending which now awaits for HCI_EVT_LE_BIG_SYNC_ESTABLISHED before proceeding to next connection.

Bluetooth: hci: Remove deadcode

2025-01-15T15:32:20+00:00

hci_bdaddr_list_del_with_flags() was added in 2020's commit 8baaa4038edb ("Bluetooth: Add bdaddr_list_with_flags for classic whitelist") but has remained unused. hci_remove_ext_adv_instance() was added in 2020's commit eca0ae4aea66 ("Bluetooth: Add initial implementation of BIS connections") but has remained unused.

Bluetooth: hci_sync: Introduce hci_cmd_sync_run/hci_cmd_sync_run_once

2024-08-30T21:56:34+00:00

This introduces hci_cmd_sync_run/hci_cmd_sync_run_once which acts like hci_cmd_sync_queue/hci_cmd_sync_queue_once but runs immediately when already on hdev->cmd_sync_work context. Signed-off-by: Luiz Augusto von Dentz

Bluetooth: hci_sync: Remove remaining dependencies of hci_request

Bluetooth: hci_core: Don't use hci_prepare_cmd

2024-07-15T14:11:29+00:00

This replaces the instance of hci_prepare_cmd with hci_cmd_sync_alloc since the former is part of hci_request.c which is considered deprecated. Signed-off-by: Luiz Augusto von Dentz
