Bluetooth: Add definitions for CIS connections

2020-01-15T21:28:51Z

These adds the HCI definitions for handling CIS connections along with ISO data packets. Signed-off-by: Luiz Augusto von Dentz Signed-off-by: Marcel Holtmann

Bluetooth: Implementation of MGMT_OP_SET_BLOCKED_KEYS.

2020-01-15T21:28:41Z

MGMT command is added to receive the list of blocked keys from user-space. The list is used to: 1) Block keys from being distributed by the device during the ke distribution phase of SMP. 2) Filter out any keys that were previously saved so they are no longer used.

Bluetooth: Add support for LE PHY Update Complete event

2020-01-04T09:49:23Z

This handles LE PHY Update Complete event and store both tx_phy and rx_phy into hci_conn. Signed-off-by: Luiz Augusto von Dentz Signed-off-by: Marcel Holtmann

Bluetooth: Remove usage of BT_ERR_RATELIMITED macro

2020-01-04T09:41:03Z

The macro is really not needed and can be replaced with either usage of bt_err_ratelimited or bt_dev_err_ratelimited. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Adding a bt_dev_warn_ratelimited macro.

2020-01-04T09:41:03Z

The macro will be used to display rate limited warning messages in the log. Signed-off-by: Alain Michaud Signed-off-by: Marcel Holtmann

Bluetooth: Add support for utilizing Fast Advertising Interval

2019-09-05T15:27:21Z

Changes made to add support for fast advertising interval as per core 4.1 specification, section 9.3.11.2. A peripheral device entering any of the following GAP modes and sending either non-connectable advertising events or scannable undirected advertising events should use adv_fast_interval2 (100ms - 150ms) for adv_fast_period(30s). - Non-Discoverable Mode - Non-Connectable Mode - Limited Discoverable Mode - General Discoverable Mode Signed-off-by: Spoorthi Ravishankar Koppad Signed-off-by: Marcel Holtmann

Bluetooth: Add debug setting for changing minimum encryption key size

2019-08-17T10:54:40Z

For testing and qualification purposes it is useful to allow changing the minimum encryption key size value that the host stack is going to enforce. This adds a new debugfs setting min_encrypt_key_size to achieve this functionality. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Add support for LE ping feature

2019-07-06T13:29:12Z

Changes made to add HCI Write Authenticated Payload timeout command for LE Ping feature. As per the Core Specification 5.0 Volume 2 Part E Section 7.3.94, the following code changes implements HCI Write Authenticated Payload timeout command for LE Ping feature.

Bluetooth: Ignore CC events not matching the last HCI command

2019-05-05T17:29:04Z

This commit makes the kernel not send the next queued HCI command until a command complete arrives for the last HCI command sent to the controller. This change avoids a problem with some buggy controllers (seen on two SKUs of QCA9377) that send an extra command complete event for the previous command after the kernel had already sent a new HCI command to the controller. The problem was reproduced when starting an active scanning procedure, where an extra command complete event arrives for the LE_SET_RANDOM_ADDR command. When this happends the kernel ends up not processing the command complete for the following commmand, LE_SET_SCAN_PARAM, and ultimately behaving as if a passive scanning procedure was being performed, when in fact controller is performing an active scanning procedure. This makes it impossible to discover BLE devices as no device found events are sent to userspace. This problem is reproducible on 100% of the attempts on the affected controllers. The extra command complete event can be seen at timestamp 27.420131 on the btmon logs bellow.
