Bluetooth: ISO: Rework sync_interval to be sync_factor

2023-06-29T17:52:18+00:00

This rework sync_interval to be sync_factor as having sync_interval in
the order of seconds is sometimes not disarable.

Wit sync_factor the application can tell how many SDU intervals it wants
to send an announcement with PA, the EA interval is set to 2 times that
so a factor of 24 of BIG SDU interval of 10ms would look like the
following:

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.

Bluetooth: ISO: Add broadcast support

2022-07-23T00:14:13+00:00

This adds broadcast support for BTPROTO_ISO by extending the
sockaddr_iso with a new struct sockaddr_iso_bc where the socket user
can set the broadcast address when receiving, the SID and the BIS
indexes it wants to synchronize.

When using BTPROTO_ISO for broadcast the roles are:

Broadcaster -> uses connect with address set to BDADDR_ANY:
> tools/isotest -s 00:00:00:00:00:00

Broadcast Receiver -> uses listen with address set to broadcaster:
> tools/isotest -d 00:AA:01:00:00:00

This introduces a new socket type BTPROTO_ISO which can be enabled with
use of ISO Socket experiemental UUID, it can used to initiate/accept
connections and transfer packets between userspace and kernel similarly
to how BTPROTO_SCO works:
