Bluetooth: use inclusive language when filtering devices

2021-06-26T05:12:44+00:00

This patch replaces some non-inclusive terms based on the appropriate
language mapping table compiled by the Bluetooth SIG:
https://specificationrefs.bluetooth.com/language-mapping/Appropriate_Language_Mapping_Table.pdf

Specifically, these terms are replaced:
blacklist -> reject list
whitelist -> accept list

Bluetooth: Move force_bredr_smp debugfs into hci_debugfs_create_bredr

2020-11-09T12:52:55+00:00

Avoid multiple attempts to create the debugfs entry, force_bredr_smp,
by moving it from the SMP registration to the BR/EDR controller init
section. hci_debugfs_create_bredr is only called when HCI_SETUP and
HCI_CONFIG is not set.

Bluetooth: debugfs option to unset MITM flag

2020-04-07T16:32:21+00:00

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.

Bluetooth: Move {min,max}_key_size debugfs into hci_debugfs_create_le

2020-01-25T14:33:52+00:00

The debugfs entries for {min,max}_key_size are created during SMP
registration and thus it might lead to multiple attempts to create the
same entries. Avoid this by moving them to the LE controller init
section.

Bluetooth: Implementation of MGMT_OP_SET_BLOCKED_KEYS.

2020-01-15T21:28:41+00:00

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 debug setting for changing minimum encryption key size

2019-08-17T10:54:40+00:00

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.
