This patch implements SMP crypto functions called ah, c1, s1 and e. It also implements auxiliary functions. All These functions are needed for SMP keys generation. Signed-off-by:

This will allow using the crypto subsystem for encrypting data. As SMP (Security Manager Protocol) is implemented almost entirely on the host side and the crypto module already implements the needed methods (AES-128), it makes sense to use it. There's now a new module option to enable/disable SMP support. Signed-off-by:

This implementation only exchanges SMP messages between the Host and the Remote. No keys are being generated. TK and STK generation will be provided in further patches. Signed-off-by:

struct l2cap_chan has now its own refcnt that is compatible with the socket refcnt, i.e., we won't see sk_refcnt = 0 and chan->refcnt > 0. Signed-off-by: -

Now socket state is tracked by struct sock and channel state is tracked by chan->state. At this point both says the same, but this is going to change when we add AMP Support for example. Signed-off-by: -

When code was moved from l2cap_core.c to l2cap_sock.c in commit 6de0702b , one line was dropped from the old __l2cap_sock_close() implementation. This sk_state change should still be in l2cap_chan_close(). Signed-off-by:

Add BT_POWER socket option used to control the power characteristics of the underlying ACL link. When the remote end has put the link in sniff mode and the host stack wants to send data we need need to explicitly exit sniff mode to work well with certain devices (For example, A2DP on Plantronics Voyager 855). However, this causes problems with HID devices. Hence, moving into active mode when sending data, irrespective of who set the sniff mode has been made as a socket option. By default, we will move into active mode. HID devices can set the L2CAP socket option to prevent this from happening. Currently, this has been implemented for L2CAP sockets. This has been tested with incoming and outgoing L2CAP sockets for HID and A2DP. Based on discussions on linux-bluetooth and patches submitted by Andrei Emeltchenko. Signed-off-by:

As we cannot relay on a userspace mgmt api implementation we should verify if pin_code_reply in fact contains the secure pin code. If userspace replied with unsecure pincode when secure was required we will send pin_code_neg_reply to the controller. Signed-off-by:

This patch adds a new field (dst_type) to the struct hci_conn which holds the type of the destination address (bdaddr_t dst). This approach is needed in order to use the struct hci_conn as an abstraction of LE connections in HCI Layer. For non-LE this field is ignored. This patch also set properly the 'dst_type' field after initializing LE hci_conn structures. Signed-off-by:

Legacy devices don't re-authenticate the link properly if a link key already exists. Thus, don't update sec_level for this case even if hci_auth_complete_evt indicates success. Otherwise the sec_level will not reflect a real security on the link. Signed-off-by:

This patch adds a timer to clear 'adv_entries' after three minutes. After some amount of time, the advertising entries cached during the last LE scan should be considered expired and they should be removed from the advertising cache. It was chosen a three minutes timeout as an initial attempt. This value might change in future. Signed-off-by:
