Bluetooth: Enable LE Enhanced Connection Complete event.

2020-04-15T13:51:05Z

In case LL Privacy is supported by the controller, it is also a good idea to use the LE Enhanced Connection Complete event for getting all information about the new connection and its addresses. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Use extra variable to make code more readable

2020-04-15T13:51:02Z

When starting active scanning for discovery the whitelist is not needed to be used. So the filter_policy is 0x00. To make the core more readable use a variable name instead of just setting 0 as paramter. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: log advertisement packet length if it gets corrected

2020-04-09T17:57:28Z

The error could indicate a problem with the Bluetooth device. It is easier to investigate if the packet's actual length gets logged, not just the fact that a discrepancy occurred. Signed-off-by: Daniels Umanovskis Reviewed-by: Alain Michaud Signed-off-by: Marcel Holtmann

Bluetooth: Always request for user confirmation for Just Works (LE SC)

2020-04-08T20:18:32Z

To improve security, always give the user-space daemon a chance to accept or reject a Just Works pairing (LE). The daemon may decide to auto-accept based on the user's intent. This patch is similar to the previous patch but applies for LE Secure Connections (SC). Signed-off-by: Sonny Sasaka Signed-off-by: Marcel Holtmann

Bluetooth: Simplify / fix return values from tk_request

2020-04-07T16:34:53Z

Some static checker run by 0day reports a variableScope warning. net/bluetooth/smp.c:870:6: warning: The scope of the variable 'err' can be reduced. [variableScope] There is no need for two separate variables holding return values. Stick with the existing variable. While at it, don't pre-initialize 'ret' because it is set in each code path. tk_request() is supposed to return a negative error code on errors, not a bluetooth return code. The calling code converts the return value to SMP_UNSPECIFIED if needed.

Bluetooth: debugfs option to unset MITM flag

2020-04-07T16:32:21Z

The BT qualification test SM/MAS/PKE/BV-01-C needs us to turn off the MITM flag when pairing, and at the same time also set the io capability to something other than no input no output. Currently the MITM flag is only unset when the io capability is set to no input no output, therefore the test cannot be executed. This patch introduces a debugfs option to force MITM flag to be turned off. Signed-off-by: Archie Pusaka Signed-off-by: Marcel Holtmann

Bluetooth: Add support for reading security information

2020-04-05T11:53:13Z

To allow userspace to make correcty security policy decision, the kernel needs to export a few details of the supported security features and encryption key size information. This command exports this information and also allows future extensions if needed. Signed-off-by: Marcel Holtmann Reviewed-by: Alain Michaud Signed-off-by: Johan Hedberg

Bluetooth: Add support for Read Local Simple Pairing Options

2020-04-05T11:53:11Z

With the Read Local Simple Pairing Options command it is possible to retrieve the support for max encryption key size supported by the controller and also if the controller correctly verifies the ECDH public key during pairing.
