* Bluetooth: Set conn state to BT_DISCONN to avoid multiple responsesBao Liang2011-02-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a minor issue that two connection responses will be sent for one L2CAP connection request. If the L2CAP connection request is first blocked due to security reason and responded with reason "security block", the state of the connection remains BT_CONNECT2. If a pairing procedure completes successfully before the ACL connection is down, local host will send another connection complete response.

* Bluetooth: Fix race condition with conn->sec_levelJohan Hedberg2011-01-192-6/+11
| | | | | | | | | | | | The conn->sec_level value is supposed to represent the current level of security that the connection has. However, by assigning to it before requesting authentication it will have the wrong value during the authentication procedure. To fix this a pending_sec_level variable is added which is used to track the desired security level while making sure that sec_level always represents the current level of security.

* Bluetooth: Fix authentication request for L2CAP raw socketsJohan Hedberg2011-01-191-1/+2
| | | | | | | | | | | | When there is an existing connection l2cap_check_security needs to be called to ensure that the security level of the new socket is fulfilled. Normally l2cap_do_start takes care of this, but that function doesn't get called for SOCK_RAW type sockets. This patch adds the necessary l2cap_check_security call to the appropriate branch in l2cap_do_connect.

* Bluetooth: Create a unified auth_type evaluation functionJohan Hedberg2011-01-191-49/+28
| | | | | | | | | | | | | | The logic for determining the needed auth_type for an L2CAP socket is rather complicated and has so far been duplicated in l2cap_check_security as well as l2cap_do_connect. Additionally the l2cap_check_security code was completely missing the handling of SOCK_RAW type sockets. This patch creates a unified function for the evaluation and makes l2cap_do_connect and l2cap_check_security use that function.

* Revert "Bluetooth: Update sec_level/auth_type for already existing connections"Johan Hedberg2011-01-191-5/+0
| | | | | | | | | | | | | | | | | | | This reverts commit 045309820afe047920a50de25634dab46a1e851d. That commit is wrong for two reasons: - The conn->sec_level shouldn't be updated without performing authentication first (as it's supposed to represent the level of security that the existing connection has) - A higher auth_type value doesn't mean "more secure" like the commit seems to assume. E.g. dedicated bonding with MITM protection is 0x03 whereas general bonding without MITM protection is 0x04. hci_conn_auth already takes care of updating conn->auth_type so hci_connect doesn't need to do it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The initialization function used by hci_open_dev (hci_init_req) sends many different HCI commands. The __hci_request function should only return when all of these commands have completed (or a timeout occurs). Several of these commands cause hci_req_complete to be called which causes __hci_request to return prematurely. This patch fixes the issue by adding a new hdev->req_last_cmd variable which is set during the initialization procedure. The hci_req_complete function will no longer mark the request as complete until the command matching hdev->req_last_cmd completes.

| * Bluetooth: Fix initial RFCOMM DLC security levelJohan Hedberg2010-12-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to commit 63ce0900 connections initiated through TTYs created with "rfcomm bind ..." would have security level BT_SECURITY_SDP instead of BT_SECURITY_LOW. This would cause instant connection failure between any two SSP capable devices due to the L2CAP connect request to RFCOMM being sent before authentication has been performed.

* | Bluetooth: Automate remote name requestsJohan Hedberg2010-12-021-18/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Bluetooth there are no automatic updates of remote device names when they get changed on the remote side. Instead, it is a good idea to do a manual name request when a new connection gets created (for whatever reason) since at this point it is very cheap (no costly baseband connection creation needed just for the sake of the name request). So far userspace has been responsible for this extra name request but tighter control is needed in order not to flood Bluetooth controllers with two many commands during connection creation. It has been shown that some controllers simply fail to function correctly if they get too many (almost) simultaneous commands during connection creation. The simplest way to acheive better control of these commands is to move their sending completely to the kernel side. This patch inserts name requests into the sequence of events that the kernel performs during connection creation. It does this after the remote features have been successfully requested and before any pending authentication requests are performed. The code will work sub-optimally with userspace versions that still do the name requesting themselves (it shouldn't break anything though) so it is recommended to combine this with a userspace software version that doesn't have automated name requests.

* Bluetooth: Fix non-SSP auth request for HIGH security level socketsJohan Hedberg2010-11-091-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | When initiating dedicated bonding a L2CAP raw socket with HIGH security level is used. The kernel is supposed to trigger the authentication request in this case but this doesn't happen currently for non-SSP (pre-2.1) devices. The reason is that the authentication request happens in the remote extended features callback which never gets called for non-SSP devices. This patch fixes the issue by requesting also authentiation in the (normal) remote features callback in the case of non-SSP devices. This rule is applied only for HIGH security level which might at first seem unintuitive since on the server socket side MEDIUM is already enough for authentication. However, for the clients we really want to prefer the server side to decide the authentication requrement in most cases, and since most client sockets use MEDIUM it's better to be avoided on the kernel side for these sockets. The important socket to request it for is the dedicated bonding one and that socket uses HIGH security level. The patch is based on the initial investigation and patch proposal from Andrei Emeltchenko <endrei.emeltchenko@nokia.com>.
