2013-10-22Bluetooth: Remove sk member from struct l2cap_chanGustavo Padovan1-2/+0
There is no access to chan->sk in L2CAP core now. This change marks the end of the task of splitting L2CAP between Core and Socket, thus sk is now gone from struct l2cap_chan. Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-22Bluetooth: Use bt_cb(skb)->chan to send raw data backGustavo Padovan1-4/+3
Instead of accessing skb->sk in L2CAP core we now compare the channel a skb belongs to and not send it back if the channel is same. This change removes another struct socket usage from L2CAP core.

2013-10-22Bluetooth: Add L2CAP channel to skb private dataGustavo Padovan1-0/+2
Adding the channel to the skb private data makes possible to us know which channel the skb we have came from. Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-21Bluetooth: Remove parent socket usage from l2cap_core.cGustavo Padovan2-10/+8
The parent socket is not used inside the L2CAP core anymore. We only lock it to indirect access through the new_connection() callback. The hold of the socket lock was moved to the new_connection() callback. Inside L2CAP core the channel lock is now used in l2cap_le_conn_ready() and l2cap_conn_ready() to protect the execution of these two functions during the handling of new incoming connections. This change remove the socket lock usage from L2CAP core while keeping the code safe against race conditions.

2013-10-21Bluetooth: Remove socket lock from l2cap_state_change()Gustavo Padovan1-24/+7
This simplify and make safer the state change handling inside l2cap_core.c. we got rid of __l2cap_state_change(). And l2cap_state_change() doesn't lock the socket anymore, instead the socket is locked inside the ops callback for state change in l2cap_sock.c. It makes the code safer because in some we were using a unlocked version, and now we are calls to l2cap_state_change(), when dealing with sockets, use the locked version.

2013-10-21Bluetooth: Hold socket in defer callback in L2CAP socketGustavo Padovan2-14/+9
In both places that we use the defer callback the socket lock is held for a indirect sk access inside __l2cap_change_state() and chan->ops->defer(), all the rest of the code between lock_sock() and release_sock() is already protected by the channel lock and won't be affected by this change. We now use l2cap_change_state(), the locked version of the change state function, and the defer callback does the locking itself now. This does not affect other uses of the defer callback.

2013-10-21Bluetooth: Do not access chan->sk directlyGustavo Padovan1-1/+2
In the process of removing socket usage from L2CAP we now access the L2CAP socket from the data member of struct l2cap_chan. For the L2CAP socket user the data member points to the L2CAP socket.

2013-10-21Bluetooth: Remove not used struct sockGustavo Padovan1-3/+1
It is a leftover from the recent effort of remove sk usage from L2CAP core. Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-21Bluetooth: Fix enabling fast connectable on LE-only controllersJohan Hedberg1-0/+3
The current "fast connectable" feature is BR/EDR-only, so add a proper check for BR/EDR support before proceeding with the associated HCI commands. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-20Bluetooth: Update Set Discoverable to support LEJohan Hedberg1-11/+69
This patch updates the Set Discoverable management command to also be applicable for LE. In particular this affects the advertising flags where we can say "general discoverable" or "limited discoverable". Since the device flags may not be up-to-date when the advertising data is written this patch introduces a get_adv_discov_flags() helper function which also looks at any pending mgmt commands (a pending set_discoverable would be the exception when the flags are not yet correct). The patch also adds HCI_DISCOVERABLE flag clearing to the mgmt_discoverable_timeout function, since the code was previously relying on the mgmt_discoverable callback to handle this, which is only called for the BR/EDR-only HCI_Write_Scan_Enable command.

2013-10-20Bluetooth: Move HCI_LIMITED_DISCOVERABLE changes to a general placeJohan Hedberg1-4/+6
We'll soon be introducing also LE support for the Set Discoverable management command, so move the HCI_LIMITED_DISCOVERABLE flag clearing and setting out from the if-branch that is only used for a BR/EDR specific HCI command. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-20Bluetooth: Fix sending write_scan_enable when BR/EDR is disabledJohan Hedberg1-2/+5
We should only send the HCI_Write_Scan_Enable command from mgmt_set_powered_failed() when BR/EDR support is enabled. This is particularly important when the discoverable setting is also tied to LE. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-20Bluetooth: Move mgmt_pending_find to avoid forward declarationsJohan Hedberg1-12/+12
We will soon need this function for updating the advertising data, so move it higher up in mgmt.c to avoid a forward declaration. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-20Bluetooth: Fix updating settings when there are no HCI commands to sendJohan Hedberg1-2/+2
It is possible that the Set Connectable management command doesn't cause any HCI commands to send (such as when BR/EDR is disabled). We can't just send a response to user space in this case but must also update the necessary device flags and settings. This patch fixes the issue by using the recently introduced set_connectable_update_settings function. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-20Bluetooth: Refactor set_connectable settings update to separate functionJohan Hedberg1-19/+27
We will need to directly update the device flags and notify user space of the new settings not just when we're powered off but also if it turns out that there are no HCI commands to send (which can happen in particular when BR/EDR is disabled). Since this is a considerable amount of code, refactor it to a separate function so it can be reused for the "no HCI commands to send" case. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-20Bluetooth: Add missing check for BREDR_ENABLED flag in update_class()Johan Hedberg1-0/+3
We shouldn't be sending the HCI_Write_Class_Of_Device command when BR/EDR is disabled since this is a BR/EDR-only command. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-20Bluetooth: Check for flag instead of features in update_adv_data()Johan Hedberg1-1/+1
It's better to check for the device flag instead of device features so that we avoid unnecessary HCI commands when the feature is supported but disabled (i.e. the flag is unset). Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-20Bluetooth: Check for flag instead of features in update_scan_rsp_data()Johan Hedberg1-1/+1

2013-10-20net: 8021q/bluetooth/bridge/can/ceph: Remove extern from function prototypesJoe Perches1-2/+2
There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.

2013-10-19Bluetooth: Fix minor coding style issue in hci_core.cMarcel Holtmann1-5/+5

2013-10-19Bluetooth: Fix UUID values in debugfs fileMarcel Holtmann1-12/+10
The uuid entry struct is used for the UUID byte stream. That is actually the wrong value. The correct value is uuid->uuid. Besides fixing this up, use the %pUb modifier to print the UUID string. However since the UUID is stored in big endian with reversed byte order, change the byte order before printing.

2013-10-19Bluetooth: Add support for setting DUT modeMarcel Holtmann1-0/+73
The Device Under Test (DUT) mode is useful for doing certification testing and so expose this as debugfs option. This mode is actually special since you can only enter it. Restoring normal operation means that a HCI Reset is required. The current mode value gets tracked as a new device flag and when disabling it, the correct command to reset the controller is sent.

2013-10-19Bluetooth: Add support for setting SSP debug modeMarcel Holtmann2-1/+55
Enabling and disabling SSP debug mode is useful for development. This adds a debugfs entry that allows to configure the SSP debug mode. On purpose this has been implemented as debugfs entry and not a public API since it is really only useful during testing and development.

2013-10-19Bluetooth: Expose debugfs entry read/write own address typeMarcel Holtmann1-0/+30
For some testing it is important to know the current own addres type, but also be able to change it. The change is lost over powery cycles and only intended for debugging. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-19Bluetooth: Select the own address type during initial setup phaseMarcel Holtmann3-15/+15
The own address type is based on the fact if the controller has a public address or not. This means that this detail can be just configured once during setup phase. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

2013-10-19Bluetooth: Move export of class of device information into hci_core.cMarcel Holtmann2-10/+26
The class of device debugfs information should be directly exported from hci_core.c and so move them over there. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-19Bluetooth: Store local version information only during setup phaseMarcel Holtmann1-8/+7
The local version information from the controller can not change since they are static. So store them only once during setup phase and not bother overwriting them every time this command gets executed.

2013-10-19Bluetooth: Add workaround for buggy max_page features page valueMarcel Holtmann2-1/+10
Some controllers list the max_page value from the extended features response as 0 when SSP has not yet been enabled. To workaround this issue, force the max_page value to 1 when SSP support has been detected. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

2013-10-18Bluetooth: Use BDADDR_BREDR type for old blacklist ioctl interfaceMarcel Holtmann1-2/+2
The old blacklist ioctl interface was only able to operate on BR/EDR addresses. So use the BDADDR_BREDR address type definition instead of an open coded magic 0 value. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-18Bluetooth: Fix ATT socket backwards compatibility with user spaceJohan Hedberg1-2/+25
Old user space versions bind the Attribute Protocol socket to BDADDR_BREDR when they should be using BDADDR_LE_PUBLIC or BDADDR_LE_RANDOM. The kernel recently introduced stricter checks on the socket parameters but we need to punch this hole for old user space versions to keep them working.
