Bluetooth: SCO: Fix UAF on sco_sock_timeout

2024-11-01T01:02:37+00:00

[ Upstream commit 1bf4470a3939c678fb822073e9ea77a0560bc6bb ] conn->sk maybe have been unlinked/freed while waiting for sco_conn_lock so this checks if the conn->sk is still valid by checking if it part of sco_sk_list.

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: Invert LE State quirk to be opt-out rather then opt-in

2024-08-15T17:07:55+00:00

This inverts the LE State quirk so by default we assume the controllers would report valid states rather than invalid which is how quirks normally behave, also this would result in HCI command failing it the LE States are really broken thus exposing the controllers that are really broken in this respect.

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

Bluetooth: hci_core: Remove usage of hci_req_sync

2024-07-15T14:11:27+00:00

Bluetooth: hci_core: cleanup struct hci_dev

2024-07-15T14:11:19+00:00

Remove unused and set but otherwise unused 'discovery_old_state' and 'sco_last_tx' members of 'struct hci_dev'. The first one is a leftover after commit 182ee45da083 ("Bluetooth: hci_sync: Rework hci_suspend_notifier"); the second one is originated from ancient 2.4.19 and I was unable to find any actual use since that.
