2011-04-18Bluetooth: Fix keeping the command timer runningVinicius Costa Gomes1-3/+2
In the teardown path the reset command is sent to the controller, this event causes the command timer to be reactivated. So the timer is removed in two situations, when the adapter isn't marked as UP and when we know that some command has been sent.

2011-04-18Bluetooth: Fix refcount balance for hci connectionVille Tervo1-2/+0
hci_io_capa_reply_evt() holds reference for hciconnection. It's useless since hci_io_capa_request_evt()/hci_simple_pair_complete_evt() already protects the connection. In addition it leaves connection open after failed SSP pairing. Signed-off-by: Ville Tervo <ville.tervo@nokia.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>

2011-04-13mac80211: Allocate new mesh path and portal tables before taking lockscozybit Inc1-24/+25

2011-04-12mac80211: Check for queued frames before entering power save.Vivek Natarajan3-8/+42
In a highly noisy environment, the tx rate of the driver drops and the application slows down since it has not yet received ACKs for the frames already queued in the hardware. Since this ACK may take more than 100ms, stopping the dev queues for entering PS at this stage breaks applications, WMM test cases in my testing. If there are frames already pending in the tx queue, postponing the PS logic helps to avoid redundant queue stops. When power save is enabled by default and in a noisy environment, this API certainly helps in improving the average throughput.

2011-04-07cfg80211: add a timer for invalid user reg hintsLuis R. Rodriguez1-1/+24
We have no other option but to inform userspace that we have queued up their regulatory hint request when we are given one given that nl80211 operates atomically on user requests. The best we can do is accept the request, and add a delayed work item for processing failure and cancel it if we succeeed. Upon failure we restore the regulatory settings and ignore the user input.

2011-04-07cfg80211: fix regulatory restore upon user hintsLuis R. Rodriguez1-1/+45
When we restore regulatory settings its possible CRDA will not reply because of a bogus user entry. In this case the bogus entry will prevent any further processing on cfg80211 for regulatory domains even if we restore regulatory settings. To prevent this we suck out all pending requests when restoring regulatory settings and add them back into the queue after we have queued up the reset work. The impact of not having this applied is that a user with privileges can issue a userspace regulatory hint while we are disasocciating and this would prevent any further processing of regulatory domains.
