Disclaimer: the code this is based on is still on review, so this is is subject to change. Having Encryption Key Size exported to userspace is needed because some profiles might have some restrictions depending on the key size used to encrypt the link. This patch series implement exporting to userspace adding one more field to the bt_security structure. For now, this only is valid for LE links, for 3.0+HS controllers the Read Encryption Key Size command is defined. The plan is to use that command for reading the key size as soon as the link is encrypted, and storing the value read in the field that was added to hci_conn. The related userspace patches should follow this series. -- Cheers, Vinicius Costa Gomes (2): Bluetooth: Add support for storing the key size Bluetooth: Add support for returning the encryption key size include/net/bluetooth/bluetooth.h | 1 + include/net/bluetooth/hci_core.h | 3 ++- net/bluetooth/hci_core.c | 3 ++- net/bluetooth/hci_event.c | 1 + net/bluetooth/l2cap_sock.c | 4 ++++ net/bluetooth/mgmt.c | 4 ++-- net/bluetooth/smp.c | 16 ++++++++++------ 7 files changed, 22 insertions(+), 10 deletions(-) -- 1.7.4.3 -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
