This is not a logical change but rather a move of the inbound firmware event handler into it's own function as it will later be called by the outbound path. The addition of the mutex is to create exclusive access to the mailbox commands between inbound and outbound handling. Signed-off-by: Ron Mercer <ron.mercer@qlogic.com> Signed-off-by: David S.

My logitec bluetooth mouse trying connect to pc, but pc side reject the connection again and again. then panic happens. The reason is due to hci_conn_del_sysfs now called in hci_event_packet, the del work is done in a workqueue, so it's possible done before skb_queue_purge called. I move the hci_conn_del_sysfs after skb_queue_purge just as that before marcel's commit. Remove the hci_conn_del_sysfs in hci_conn_hash_flush as well due to hci_conn_del will deal with the work.

2009-02-27Bluetooth: Permit BT_SECURITY also for L2CAP raw socketsMarcel Holtmann
Userspace pairing code can be simplified if it doesn't have to fall back to using L2CAP_LM in the case of L2CAP raw sockets. This patch allows the BT_SECURITY socket option to be used for these sockets. Signed-off-by: Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Fix RFCOMM usage of in-kernel L2CAP socketsMarcel Holtmann
The CID value of L2CAP sockets need to be set to zero. All userspace applications do this via memset() on the sockaddr_l2 structure. The RFCOMM implementation uses in-kernel L2CAP sockets and so it has to make sure that l2_cid is set to zero. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Disallow usage of L2CAP CID setting for nowMarcel Holtmann
In the future the L2CAP layer will have full support for fixed channels and right now it already can export the channel assignment, but for the functions bind() and connect() the usage of only CID 0 is allowed. This allows an easy detection if the kernel supports fixed channels or not, because otherwise it would impossible for application to tell. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Change RFCOMM to use BT_CONNECT2 for BT_DEFER_SETUPMarcel Holtmann
When BT_DEFER_SETUP is enabled on a RFCOMM socket, then switch its current state from BT_OPEN to BT_CONNECT2. This gives the Bluetooth core a unified way to handle L2CAP and RFCOMM sockets. The BT_CONNECT2 state is designated for incoming connections. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Fix poll() misbehavior when using BT_DEFER_SETUPMarcel Holtmann
When BT_DEFER_SETUP has been enabled on a Bluetooth socket it keeps signaling POLLIN all the time. This is a wrong behavior. The POLLIN should only be signaled if the client socket is in BT_CONNECT2 state and the parent has been BT_DEFER_SETUP enabled. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Set authentication requirement before requesting itMarcel Holtmann
The authentication requirement got only updated when the security level increased. This is a wrong behavior. The authentication requirement is read by the Bluetooth daemon to make proper decisions when handling the IO capabilities exchange. So set the value that is currently expected by the higher layers like L2CAP and RFCOMM. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Fix authentication requirements for L2CAP security checkMarcel Holtmann
The L2CAP layer can trigger the authentication via an ACL connection or later on to increase the security level. When increasing the security level it didn't use the same authentication requirements when triggering a new ACL connection. Make sure that exactly the same authentication requirements are used. The only exception here are the L2CAP raw sockets which are only used for dedicated bonding. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Ask upper layers for HCI disconnect reasonMarcel Holtmann
Some of the qualification tests demand that in case of failures in L2CAP the HCI disconnect should indicate a reason why L2CAP fails. This is a bluntly layer violation since multiple L2CAP connections could be using the same ACL and thus forcing a disconnect reason is not a good idea. To comply with the Bluetooth test specification, the disconnect reason is now stored in the L2CAP connection structure and every time a new L2CAP channel is added it will set back to its default. So only in the case where the L2CAP channel with the disconnect reason is really the last one, it will propagated to the HCI layer. The HCI layer has been extended with a disconnect indication that allows it to ask upper layers for a disconnect reason. The upper layer must not support this callback and in that case it will nicely default to the existing behavior. If an upper layer like L2CAP can provide a disconnect reason that one will be used to disconnect the ACL or SCO link. No modification to the ACL disconnect timeout have been made. So in case of Linux to Linux connection the initiator will disconnect the ACL link before the acceptor side can signal the specific disconnect reason. That is perfectly fine since Linux doesn't make use of this value anyway. The L2CAP layer has a perfect valid error code for rejecting connection due to a security violation. It is unclear why the Bluetooth specification insists on having specific HCI disconnect reason. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Add CID field to L2CAP socket address structureMarcel Holtmann
In preparation for L2CAP fixed channel support, the CID value of a L2CAP connection needs to be accessible via the socket interface. The CID is the connection identifier and exists as source and destination value. So extend the L2CAP socket address structure with this field and change getsockname() and getpeername() to fill it in. The bind() and connect() functions have been modified to handle L2CAP socket address structures of variable sizes. This makes them future proof if additional fields need to be added. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Request L2CAP fixed channel list if availableMarcel Holtmann
If the extended features mask indicates support for fixed channels, request the list of available fixed channels. This also enables the fixed channel features bit so remote implementations can request information about it. Currently only the signal channel will be listed. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-02-27Bluetooth: Don't enforce authentication for L2CAP PSM 1 and 3Marcel Holtmann
The recommendation for the L2CAP PSM 1 (SDP) is to not use any kind of authentication or encryption. So don't trigger authentication for incoming and outgoing SDP connections. For L2CAP PSM 3 (RFCOMM) there is no clear requirement, but with Bluetooth 2.1 the initiator is required to enable authentication and encryption first and this gets enforced. So there is no need to trigger an additional authentication step. The RFCOMM service security will make sure that a secure enough link key is present. When the encryption gets enabled after the SDP connection setup, then switch the security level from SDP to low security. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
