2014-07-08Bluetooth: Fix check for re-enabling advertisingJohan Hedberg
There are many different places that can disable LE scanning but we only want to re-enable advertising in hci_cc_le_set_scan_enable() for a very specific use case, which is when the active scanning part of Start Discovery is complete. Because of this, fix the discovery state check to test for the exact state. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2014-07-08Bluetooth: Fix advertising and active scanning co-existenceJohan Hedberg
Many controllers allow simultaneous active scanning and advertising (e.g. Intel and Broadcom) but some do not (e.g. CSR). It's therefore safest to implement mutual exclusion of these states in the kernel. This patch ensures that the two states are never entered simultaneously. Extra precaution needs to be taken for outgoing connection attempts in slave role (i.e. through directed advertising) in which case the operation that came first has precedence and the one that comes after gets a rejection.

2014-07-08Bluetooth: Stop advertising always before initiating a connectionJohan Hedberg
Most controllers do not support advertising while initiating an LE connection. We also have to first disable current advertising if the initiation is going to happen through direct advertising. Therefore, simply stop advertising as the first thing when starting to issue commands to establish an LE connection.

2014-07-08Bluetooth: Use the correct flag to decide to disable advertisingJohan Hedberg
When deciding to call disable_advertising() we're interested in the real state instead of the mgmt setting. Use therefore HCI_LE_ADV instead of the HCI_ADVERTISING flag. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2014-07-08Bluetooth: Simplify usage of the enable_advertising functionJohan Hedberg
By adding support for disabling advertising when necessary and doing the checks for existing LE connections inside the enable_advertising function we can simplify the calling code quite a lot.

2014-07-08Bluetooth: Use real advertising state to random address update decisionJohan Hedberg
Now that we have a flag for tracking the real advertising state we should use that to determine whether it's safe to update the random address or not. The couple of places that were clearing the flag due to a pending request need to be updated too.

2014-07-08Bluetooth: Remove unnecessary mgmt_advertising functionJohan Hedberg
Since the real advertising state is now tracked with its own flag we can simply set/unset the HCI_ADVERTISING flag in the set_advertising_complete function. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2014-07-08Bluetooth: Add flag to track the real advertising stateJohan Hedberg
Having a single HCI_ADVERTISING flag is problematic since it tries to track both the real advertising state and the corresponding mgmt setting. To make the logic simpler and more reliable add a new flag that only tracks the actual advertising state that has been written to the controller.

2014-07-07rt2800usb: Don't perform DMA from stackAndrea Merello
Function rt2800usb_autorun_detect() passes the address of a variable allocated onto the stack to be used for DMA by the USB layer. This has been caught by my debugging-enabled kernel. This patch change things in order to allocate that variable via kmalloc, and it adjusts things to handle the kmalloc failure case, propagating the error.

2014-07-07iwlwifi: mvm: Use CS tx block bit for AP/GOAndrei Otcheretianski
An AP/GO may perform the channel switch slightly before its stations. This scenario may result in packet loss, since the transmission may start before the client is actually on a new channel. In order to prevent potential packet loss disable tx to all the stations when the channel switch flow starts. Clear the disable_tx bit when a station is seen on a target channel, or after IWL_MVM_CS_UNBLOCK_TX_TIMEOUT beacons on a new channel. In addition call ieee80211_sta_block_awake in order to inform mac80211 that the frames for this station should be buffered.

Start the new BT Coex implementation. Don't react to notifications for now - only the initial configuration is implemented. The rest will happen in next patches. Since coex.c now uses the new the new structures in all functions, we need to adapt the code to compile, even if it doesn't run yet. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2014-07-07iwlwifi: mvm: BT Coex - prepare towards new APIEmmanuel Grumbach
A new API is coming. This new API is not backward compatible. So we need to keep the old commands to be able to work with the former API. Move all the current code into a new file: coex_legacy. If a firmware with the new API is detected, we currently just bail out since the implementation of the new API will come in future patches.

2014-07-07Bluetooth: Don't try background scanning if LE is not enabledJohan Hedberg
For adapters that do not support LE and ones where LE hasn't been enabled we shouldn't be trying to initiate background scanning. This patch adds an extra check to the hci_update_background_scan() to ensure that we bail out if HCI_LE_ENABLED is not set. Since we do allow user space to feed the kernel with LE connection parameters even when LE is not enabled we now need to also call hci_update_background_scan() as soon as LE gets enabled so that scanning gets started if necessary.

2014-07-07Bluetooth: Pass desired connection role to hci_connect_le()Johan Hedberg
If we have both LE scanning and advertising simultaneously enabled we need a way to tell hci_connect_le() in which role to initiate a connection. This patch adds a new parameter to the function to give it the necessary information. For auto-connect and mgmt_pair_device we always use master role, whereas for L2CAP users (in practice sockets) we use slave role whenever HCI_ADVERTISING is set and master role otherwise.

2014-07-07Bluetooth: Remove auth_type parameter from hci_connect_le()Johan Hedberg
The auth_type value which gets assigned to hci_conn->auth_type is something that's only used for BR/EDR connections and is of no value for LE connections. It makes therefore little sense to pass it to the hci_connect_le() function. This patch removes the parameter from the function.
