2012-05-14Bluetooth: mgmt: Fix device_connected sending orderJohan Hedberg
The mgmt_ev_device_connected signal must be sent before any event indications happen for sockets associated with the connection. Otherwise e.g. device authorization for the sockets will fail with ENOTCONN as user space things that there is no baseband link. This patch fixes the issue by ensuring that the device_connected event if sent (if it hasn't been so already) as soon as the first ACL data packet arrives from the remote device.

2012-05-14Bluetooth: notify userspace of security level changeGustavo Padovan
It fixes L2CAP socket based security level elevation during a connection. The HID profile needs this (for keyboards) and it is the only way to achieve the security level elevation when using the management interface to talk to the kernel (hence the management enabling patch being the one that exposes this issue). It enables the userspace a security level change when the socket is already connected and create a way to notify the socket the result of the request. At the moment of the request the socket is made non writable, if the request fails the connections closes, otherwise the socket is made writable again, POLL_OUT is emmited.

2012-03-03Bluetooth: Don't force DISCOVERY_STOPPED state in inquiry_cache_flushAndre Guedes
We are not supposed to force DISCOVERY_STOPPED in inquiry_cache_flush because we may break the discovery state machine. For instance, during interleaved discovery, when we are about to start inquiry, the state machine forcibly goes to DISCOVERY_STOPPED while it should stay in DISCOVERY_FINDING state. This problem results in unexpected behaviors such as sending two mgmt_discovering events to userspace (when only one event is expected) and Stop Discovery failures.

The L2CAP timeout constants are always used in form of jiffies. So just include the conversion from msecs in the define itself. This has the advantage of making the code where the timeout is used more readable. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2012-03-01Bluetooth: mgmt: Centralize message length checksJohan Hedberg
This patch moves the command length information into the command handler table allowing the removal of length checks from the handler functions and doing the check in a single place before calling the handler function.

2012-03-01Bluetooth: mgmt: Move command handlers into a tableJohan Hedberg
By moving the command handlers into a table (the index being equal to the opcode) the lookup is made a bit more efficient. Having a struct to describe each handler also paves the way to add more meta-data for each handler, e.g. the minimum message size for the command and allow handling of common tasks like this in a centralized place.

2012-03-01Bluetooth: mgmt: Initialize HCI_MGMT flag for any commandJohan Hedberg
The read_controller_info is typically the first command that user space sends when taking a controller into use. This is also the reason why this command has been used as the trigger to set the HCI_MGMT flag. However, when not running the user-space daemon and using command line tools it is possible that read_controller_info is not the first controller specific command. This patch moves the HCI_MGMT initialization to a generic place where it will be set for whatever happens to be the first mgmt command targetting a specific controller.

2012-03-01Bluetooth: mgmt: Refactor hci_dev lookup for commandsJohan Hedberg
Almost all mgmt commands need to lookup a struct hci_dev based on the index received within the mgmt headers. It makese therefore sense to look this up in a single place and then just pass the hdev pointer to each command handler function.

2012-03-01Bluetooth: Fix init sequence for some CSR based controllersJohan Hedberg
Some CSR controllers will generate a spontaneous reset during init and just eat up any pending command without sending a command complete for it. This patch solves the issue by just resending whatever was the last sent command. hci_send_cmd is not used since we need to bypass all other commands in the send queue.

2012-02-29Bluetooth: change min_t() cast in hci_reassembly()Dan Carpenter
"count" is type int so the cast to __u16 truncates the high bits away and triggers a Smatch static checker warning.

2012-02-28Bluetooth: Remove redundant read_host_features commandsJohan Hedberg
Previously the write_le_enable would trigger a read_host_features command but since we have access to the value LE support was set to we can simply just clear or set the bit in hdev->host_features. This also removes a second unnecessary read_host_features command from the device initialization procedure since LE is only enabled after the first read_host_features command completes.
