Bluetooth: btusb: Fix CSR clones again by re-adding ERR_DATA_REPORTING quirk

2022-12-02T21:09:30+00:00

A patch series by a Qualcomm engineer essentially removed my quirk/workaround because they thought it was unnecessary. It wasn't, and it broke everything again: https://patchwork.kernel.org/project/netdevbpf/list/?series=661703&archive=both&state=* He argues that the quirk is not necessary because the code should check if the dongle says if it's supported or not. The problem is that for these Chinese CSR clones they say that it would work: = New Index: 00:00:00:00:00:00 (Primary,USB,hci0) = Open Index: 00:00:00:00:00:00 < HCI Command: Read Local Version Information (0x04|0x0001) plen 0 > HCI Event: Command Complete (0x0e) plen 12 > [hci0] 11.276039 Read Local Version Information (0x04|0x0001) ncmd 1 Status: Success (0x00) HCI version: Bluetooth 5.0 (0x09) - Revision 2064 (0x0810) LMP version: Bluetooth 5.0 (0x09) - Subversion 8978 (0x2312) Manufacturer: Cambridge Silicon Radio (10) ... < HCI Command: Read Local Supported Features (0x04|0x0003) plen 0 > HCI Event: Command Complete (0x0e) plen 68 > [hci0] 11.668030 Read Local Supported Commands (0x04|0x0002) ncmd 1 Status: Success (0x00) Commands: 163 entries ...

Bluetooth: Add experimental wrapper for MGMT based mesh

Bluetooth: Implement support for Mesh

2022-09-06T20:18:24+00:00

The patch adds state bits, storage and HCI command chains for sending and receiving Bluetooth Mesh advertising packets, and delivery to requesting user space processes. It specifically creates 4 new MGMT commands and 2 new MGMT events: MGMT_OP_SET_MESH_RECEIVER - Sets passive scan parameters and a list of AD Types which will trigger Mesh Packet Received events MGMT_OP_MESH_READ_FEATURES - Returns information on how many outbound Mesh packets can be simultaneously queued, and what the currently queued handles are. MGMT_OP_MESH_SEND - Command to queue a specific outbound Mesh packet, with the number of times it should be sent, and the BD Addr to use. Discrete advertisments are added to the ADV Instance list. MGMT_OP_MESH_SEND_CANCEL - Command to cancel a prior outbound message request. MGMT_EV_MESH_DEVICE_FOUND - Event to deliver entire received Mesh Advertisement packet, along with timing information. MGMT_EV_MESH_PACKET_CMPLT - Event to indicate that an outbound packet is no longer queued for delivery. Signed-off-by: Brian Gix Signed-off-by: Luiz Augusto von Dentz

Bluetooth: Move hci_abort_conn to hci_conn.c

2022-08-31T22:45:56+00:00

hci_abort_conn() is a wrapper around a number of DISCONNECT and CREATE_CONN_CANCEL commands that was being invoked from hci_request request queues, which are now deprecated. There are two versions: hci_abort_conn() which can be invoked from the hci_event thread, and hci_abort_conn_sync() which can be invoked within a hci_sync cmd chain.

Bluetooth: convert hci_update_adv_data to hci_sync

2022-08-25T23:20:30+00:00

hci_update_adv_data() is called from hci_event and hci_core due to events from the controller. The prior function used the deprecated hci_request method, and the new one uses hci_sync.c Signed-off-by: Brian Gix Signed-off-by: Luiz Augusto von Dentz

Bluetooth: move hci_get_random_address() to hci_sync

2022-08-25T23:20:11+00:00

This function has no dependencies on the deprecated hci_request mechanism, so has been moved unchanged to hci_sync.c Signed-off-by: Brian Gix Signed-off-by: Luiz Augusto von Dentz
