Bluetooth: Fix bogus check for re-auth no supported with non-ssp

2023-12-22T17:56:21Z

This reverts 19f8def031bfa50c579149b200bfeeb919727b27 "Bluetooth: Fix auth_complete_evt for legacy units" which seems to be working around a bug on a broken controller rather then any limitation imposed by the Bluetooth spec, in fact if there ws not possible to re-auth the command shall fail not succeed.

Bluetooth: hci_core: Remove le_restart_scan work

2023-12-22T17:55:17Z

This removes le_restart_scan work and instead just disables controller duplicate filtering when discovery result_filtering is enabled and HCI_QUIRK_STRICT_DUPLICATE_FILTER is set.

Bluetooth: ISO: Reassociate a socket with an active BIS

2023-12-22T17:53:29Z

For ISO Broadcast, all BISes from a BIG have the same lifespan - they cannot be created or terminated independently from each other. This links together all BIS hcons that are part of the same BIG, so all hcons are kept alive as long as the BIG is active. If multiple BIS sockets are opened for a BIG handle, and only part of them are closed at some point, the associated hcons will be marked as open. If new sockets will later be opened for the same BIG, they will be reassociated with the open BIS hcons. All BIS hcons will be cleaned up and the BIG will be terminated when the last BIS socket is closed from userspace. Signed-off-by: Iulia Tanasescu Signed-off-by: Luiz Augusto von Dentz

Bluetooth: MGMT/SMP: Fix address type when using SMP over BREDR/LE

2023-12-15T16:53:09Z

If two Bluetooth devices both support BR/EDR and BLE, and also support Secure Connections, then they only need to pair once. The LTK generated during the LE pairing process may be converted into a BR/EDR link key for BR/EDR transport, and conversely, a link key generated during the BR/EDR SSP pairing process can be converted into an LTK for LE transport. Hence, the link type of the link key and LTK is not fixed, they can be either an LE LINK or an ACL LINK. Currently, in the mgmt_new_irk/ltk/crsk/link_key functions, the link type is fixed, which could lead to incorrect address types being reported to the application layer. Therefore, it is necessary to add link_type/addr_type to the smp_irk/ltk/crsk and link_key, to ensure the generation of the correct address type.

Bluetooth: hci_core: Fix hci_conn_hash_lookup_cis

2023-12-15T16:52:06Z

hci_conn_hash_lookup_cis shall always match the requested CIG and CIS ids even when they are unset as otherwise it result in not being able to bind/connect different sockets to the same address as that would result in having multiple sockets mapping to the same hci_conn which doesn't really work and prevents BAP audio configuration such as AC 6(i) when CIG and CIS are left unset.

Bluetooth: Make handle of hci_conn be unique

2023-10-23T18:03:20Z

The handle of new hci_conn is always HCI_CONN_HANDLE_MAX + 1 if the handle of the first hci_conn entry in hci_dev->conn_hash->list is not HCI_CONN_HANDLE_MAX + 1. Use ida to manage the allocation of hci_conn->handle to make it be unique.

Bluetooth: ISO: Fix bcast listener cleanup

2023-10-23T18:02:31Z

This fixes the cleanup callback for slave bis and pa sync hcons. Closing all bis hcons will trigger BIG Terminate Sync, while closing all bises and the pa sync hcon will also trigger PA Terminate Sync. Signed-off-by: Iulia Tanasescu Signed-off-by: Luiz Augusto von Dentz

Bluetooth: ISO: Pass BIG encryption info through QoS

2023-10-23T17:58:18Z

This enables a broadcast sink to be informed if the PA it has synced with is associated with an encrypted BIG, by retrieving the socket QoS and checking the encryption field. After PA sync has been successfully established and the first BIGInfo advertising report is received, a new hcon is added and notified to the ISO layer. The ISO layer sets the encryption field of the socket and hcon QoS according to the encryption parameter of the BIGInfo advertising report event. After that, the userspace is woken up, and the QoS of the new PA sync socket can be read, to inspect the encryption field and follow up accordingly.

Bluetooth: ISO: Fix BIS cleanup

2023-10-23T17:54:06Z

This fixes the master BIS cleanup procedure - as opposed to CIS cleanup, no HCI disconnect command should be issued. A master BIS should only be terminated by disabling periodic and extended advertising, and terminating the BIG. In case of a Broadcast Receiver, all BIS and PA connections can be cleaned up by calling hci_conn_failed, since it contains all function calls that are necessary for successful cleanup.
