Return-Path: From: Vinicius Costa Gomes To: linux-bluetooth@vger.kernel.org Cc: Vinicius Costa Gomes Subject: [RFC 00/15] SM Phase 3 patches Date: Tue, 5 Apr 2011 23:11:13 -0300 Message-Id: <1302055888-28177-1-git-send-email-vinicius.gomes@openbossa.org> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: Hi, Disclaimer: these patches are implememented on top of the previous SM work, so they are subject to change. These patches start support for generating and storing the keys produced during SM Phase 3. These patches will open the way for having proper pairing over Low Energy connections. As standard HCI commands don't provide any way for being notified of new Low Energy keys, these patches extend some commands and events from the Management Interface. I still don't like the way that the STK is stored: "Bluetooth: Use the link key list to temporarily store the STK" I would like very much to hear some alternative ideas. Another thing that I would like your opinion on is that some LE profiles have some restrictions on the size of the key that was used for encryption. I added a new field to struct bt_security for this purpose: "Bluetooth: Add support for returning the encryption key size" The associated userspace patches can be found here[1]. -- Cheers, [1] git://git.infradead.org/users/vcgomes/bluez.git mgmt http://git.infradead.org/users/vcgomes/bluez.git (branch mgmt) Vinicius Costa Gomes (15): Bluetooth: Add support for SMP phase 3 (key distribution) Bluetooth: Fix sending wrong IO Capabilities value Bluetooth: Add new structures for supporting SM key distribution Bluetooth: Add functions to manipulate the link key list for SMP Bluetooth: Reject an encryption request when the key isn't found Bluetooth: Add support for providing parameters to LE Start Encryption Bluetooth: Fix SM pairing parameters negotiation Bluetooth: Add support for storing the LTK Bluetooth: Use the link key list to temporarily store the STK Bluetooth: Use the stored LTK for restabilishing security Bluetooth: Remove unused field in hci_conn Bluetooth: Add support for communicating keys with userspace Bluetooth: Fix style issues reported by checkpatch.pl Bluetooth: Add support for storing the key length Bluetooth: Add support for returning the encryption key size include/net/bluetooth/bluetooth.h | 34 +++--- include/net/bluetooth/hci_core.h | 29 +++++- include/net/bluetooth/mgmt.h | 4 +- include/net/bluetooth/smp.h | 1 + net/bluetooth/hci_conn.c | 5 +- net/bluetooth/hci_core.c | 82 +++++++++++++ net/bluetooth/hci_event.c | 19 +++- net/bluetooth/l2cap_core.c | 1 + net/bluetooth/l2cap_sock.c | 4 + net/bluetooth/mgmt.c | 60 ++++++++--- net/bluetooth/smp.c | 227 ++++++++++++++++++++++++++++++++++--- 11 files changed, 412 insertions(+), 54 deletions(-) -- 1.7.4.1
