Bluetooth: Fix faulty expression for minimum encryption key size check

2019-07-03T08:09:09Z

Fix minimum encryption key size check so that HCI_MIN_ENC_KEY_SIZE is also allowed as stated in the comment. This bug caused connection problems with devices having maximum encryption key size of 7 octets (56-bit).

ipv6: constify rt6_nexthop()

2019-06-26T20:26:08Z

There is no functional change in this patch, it only prepares the next one. rt6_nexthop() will be used by ip6_dst_lookup_neigh(), which uses const variables. Signed-off-by: Nicolas Dichtel Reported-by: kbuild test robot Acked-by: Nick Desaulniers Signed-off-by: David S. Miller

Bluetooth: Fix regression with minimum encryption key size alignment

2019-06-22T16:07:39Z

When trying to align the minimum encryption key size requirement for Bluetooth connections, it turns out doing this in a central location in the HCI connection handling code is not possible. Original Bluetooth version up to 2.0 used a security model where the L2CAP service would enforce authentication and encryption. Starting with Bluetooth 2.1 and Secure Simple Pairing that model has changed into that the connection initiator is responsible for providing an encrypted ACL link before any L2CAP communication can happen. Now connecting Bluetooth 2.1 or later devices with Bluetooth 2.0 and before devices are causing a regression. The encryption key size check needs to be moved out of the HCI connection handling into the L2CAP channel setup. To achieve this, the current check inside hci_conn_security() has been moved into l2cap_check_enc_key_size() helper function and then called from four decisions point inside L2CAP to cover all combinations of Secure Simple Pairing enabled devices and device using legacy pairing and legacy service security model.
