2011-11-09Bluetooth: Remove redundant hci_dev comparisons in mgmt lookupsJohan Hedberg
Now that pending commands are hci_dev specific there's no need to check whether a command matches hci_dev when iterating through them. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>

2011-11-09Bluetooth: Move pending management command list into struct hci_devJohan Hedberg
This patch moves the pending management command list (previously global to mgmt.c) into struct hci_dev. This makes it possible to do proper locking when accessing it (through the existing hci_dev locks) and thereby avoid race conditions.

2011-11-09Bluetooth: Pass full hci_dev struct to mgmt callbacksJohan Hedberg
The current global pending command list in mgmt.c is racy. Possibly the simplest way to fix it is to have per-hci dev lists instead of a global one (all commands that need a pending struct are hci_dev specific). This way the list can be protected using the already existing per-hci dev lock. To enable this refactoring the first thing that needs to be done is to ensure that the mgmt functions have access to the hci_dev struct (instead of just the dev id).

2011-11-08Bluetooth: Periodic Inquiry and DiscoveryAndre Guedes
By using periodic inquiry command we're not able to detect correctly when the controller has started inquiry. Today we have this workaround in inquiry result event handler to set the HCI_INQUIRY flag when it sees the first inquiry result event. This workaround isn't enough because the device may be performing an inquiry but the HCI_INQUIRY flag is not set. For instance, if there is no device in range, no inquiry result event is generated, consequently, the HCI_INQUIRY flags isn't set when it should so. We rely on HCI_INQUIRY flag to implement the discovery procedure properly. So, as we aren't able to clear/set the HCI_INQUIRY flag in a reliable manner, periodic inquiry events shouldn't change the HCI_INQUIRY flag. Thus, due to that issue and in order to keep compatibility with userspace, periodic inquiry events shouldn't send mgmt discovering events. In future, we might track if periodic inquiry is enabled or not. By tracking this state we'll be able to do some improvements in Discovery such as failing MGMT_OP_START_DISCOVERY command in case periodic inquiry is on. We can also send no mgmt_device_found event if periodic inquiry is on. Signed-off-by: Andre Guedes <andre.guedes@openbossa.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-11-08Bluetooth: Create hci_cancel_inquiry()Andre Guedes
This patch adds a function to hci_core to cancel an ongoing inquiry. According to the Bluetooth spec, the inquiry cancel command should only be issued after the inquiry command has been issued, a command status event has been received for the inquiry command, and before the inquiry complete event occurs. As HCI_INQUIRY flag is only set just after an inquiry command status event occurs and it is cleared just after an inquiry complete event occurs, the inquiry cancel command should be issued only if HCI_INQUIRY flag is set. Additionally, cancel inquiry related code from stop_discovery() were replaced by a hci_cancel_inquiry() call. Signed-off-by: Andre Guedes <andre.guedes@openbossa.org> Signed-off-by: Gustavo F.

2011-11-07Bluetooth: recalculate priorities when channels are starvingLuiz Augusto von Dentz
To avoid starvation the priority is recalculated so that the starving channels are promoted to HCI_PRIO_MAX - 1 (6). HCI_PRIO_MAX (7) is considered special, because it requires CAP_NET_ADMIN capability which can be used to provide more guaranties, so it is not used when promoting.

2011-11-07Bluetooth: hidp: Fix module reference cleanupDavid Herrmann
Calling module_put(THIS_MODULE) is *never* safe when we cannot go sure that we own at least two references. This is because the call may unload our module before it returns and then the "return" will jump into invalid memory. Gladly, module.h provides a wrapper for kthread-users: module_put_and_exit(). This puts our module and then exits the kthread without returning to the module. This patch fixes the hidp kthread to use this wrapper instead of manually freeing its own reference. See nfsd or lockd for other kthreads using this. Calling __module_get() inside the kthread is safe as the hidp module will always wait until the kthread sets "waiting_for_startup" to 0.

2011-11-07Bluetooth: Increase HCI reset timeout in hci_dev_do_closeSzymon Janc
I've noticed that my CSR usb dongle was not working if it was plugged in when PC was booting. It looks like I get two HCI reset command complete events (see hcidump logs below). The root cause is reset called from off_timer. Timeout for this reset to complete is set to 250ms and my bt dongle requires more time for replying with command complete event. After that, chip seems to reply with reset command complete event for next non-reset command. Attached patch increase mentioned timeout to HCI_INIT_TIMEOUT, this value is already used for timeouting hci_reset_req in hci_dev_reset(). This might also be related to BT not working after suspend that was reported here some time ago.

2011-11-07Bluetooth: Make hci_unregister_dev return voidDavid Herrmann
hci_unregister_dev cannot fail and always returns 0. The drivers already ignore the return value so we can safely make it return void.

2011-11-07Bluetooth: Replace rfcomm tty tasklet by workqueueDavid Herrmann
Remove old tasklets and replace by workqueue. To avoid reentrancy (which tasklets always avoid) we use the system_nrt_wq. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>

Forward error codes from tty core to the rfcomm_init caller instead of using generic -1 errors. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-11-07Bluetooth: Use miliseconds for L2CAP channel timeoutsAndrzej Kaczmarek
Timers set by __set_chan_timer() should use miliseconds instead of jiffies. Commit 942ecc9c4643db5ce071562e0a23f99464d6b461 updated l2cap_set_timer() so it expects timeout to be specified in msecs instead of jiffies. This makes timeouts unreliable when CONFIG_HZ is not set to 1000. Signed-off-by: Andrzej Kaczmarek <andrzej.kaczmarek@tieto.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
