The spectral scan support activated through ATH9K_DEBUGFS depends on RELAY for the kernel->userspace communication. Not activating RELAY causes build failures. The RELAY is added as select instead of depend to do it similar like the only other user of RELAY: BLK_DEV_IO_TRACE Signed-off-by:

It's observed that reconfiguration of tx buffer size before association can cause data path failure in firmware after associated. Although this is only found with PCIe cards, but potentially it could happen with any other interfaces as well. The tx buffer reconfiguration is not really useful in firmware. Let's remove it for all interfaces. Signed-off-by:

This patch is based on "iwlwifi: report A-MPDU status". (12bf6f45) Since the firmware will give us an A-MPDU bit and only a single PHY information packet for all the subframes in an A-MPDU, we can easily report the minimal A-MPDU information for radiotap.

This patch reduces the critical section protected by sco_conn_lock in sco_conn_ready function. The lock is acquired only when it is really needed. This patch fixes the following lockdep warning which is generated when the host terminates a SCO connection. Today, this warning is a false positive. There is no way those two threads reported by lockdep are running at the same time since hdev->workqueue (where rx_work is queued) is single-thread. However, if somehow this behavior is changed in future, we will have a potential deadlock. ====================================================== [ INFO: possible circular locking dependency detected ] 3.8.0-rc1+ #7 Not tainted ------------------------------------------------------- kworker/u:1H/1018 is trying to acquire lock: (&(&conn->lock)->rlock){+.+...}, at: [<ffffffffa0033ba6>] sco_chan_del+0x66/0x190 [bluetooth] but task is already holding lock: (slock-AF_BLUETOOTH-BTPROTO_SCO){+.+...}, at: [<ffffffffa0033d5a>] sco_conn_del+0x8a/0xe0 [bluetooth] which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (slock-AF_BLUETOOTH-BTPROTO_SCO){+.+...}: [<ffffffff81083011>] lock_acquire+0xb1/0xe0 [<ffffffff813efd01>] _raw_spin_lock+0x41/0x80 [<ffffffffa003436e>] sco_connect_cfm+0xbe/0x350 [bluetooth] [<ffffffffa0015d6c>] hci_event_packet+0xd3c/0x29b0 [bluetooth] [<ffffffffa0004583>] hci_rx_work+0x133/0x870 [bluetooth] [<ffffffff8104d65f>] process_one_work+0x2bf/0x4f0 [<ffffffff81050022>] worker_thread+0x2b2/0x3e0 [<ffffffff81056021>] kthread+0xd1/0xe0 [<ffffffff813f14bc>] ret_from_fork+0x7c/0xb0 -> #0 (&(&conn->lock)->rlock){+.+...}: [<ffffffff81082215>] __lock_acquire+0x1465/0x1c70 [<ffffffff81083011>] lock_acquire+0xb1/0xe0 [<ffffffff813efd01>] _raw_spin_lock+0x41/0x80 [<ffffffffa0033ba6>] sco_chan_del+0x66/0x190 [bluetooth] [<ffffffffa0033d6d>] sco_conn_del+0x9d/0xe0 [bluetooth] [<ffffffffa0034653>] sco_disconn_cfm+0x53/0x60 [bluetooth] [<ffffffffa000fef3>] hci_disconn_complete_evt.isra.54+0x363/0x3c0 [bluetooth] [<ffffffffa00150f7>] hci_event_packet+0xc7/0x29b0 [bluetooth] [<ffffffffa0004583>] hci_rx_work+0x133/0x870 [bluetooth] [<ffffffff8104d65f>] process_one_work+0x2bf/0x4f0 [<ffffffff81050022>] worker_thread+0x2b2/0x3e0 [<ffffffff81056021>] kthread+0xd1/0xe0 [<ffffffff813f14bc>] ret_from_fork+0x7c/0xb0 other info that might help us debug this: Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(slock-AF_BLUETOOTH-BTPROTO_SCO); lock(&(&conn->lock)->rlock); lock(slock-AF_BLUETOOTH-BTPROTO_SCO); lock(&(&conn->lock)->rlock); *** DEADLOCK *** 4 locks held by kworker/u:1H/1018: #0: (hdev->name#2){.+.+.+}, at: [<ffffffff8104d5f8>] process_one_work+0x258/0x4f0 #1: ((&hdev->rx_work)){+.+.+.}, at: [<ffffffff8104d5f8>] process_one_work+0x258/0x4f0 #2: (&hdev->lock){+.+.+.}, at: [<ffffffffa000fbe9>] hci_disconn_complete_evt.isra.54+0x59/0x3c0 [bluetooth] #3: (slock-AF_BLUETOOTH-BTPROTO_SCO){+.+...}, at: [<ffffffffa0033d5a>] sco_conn_del+0x8a/0xe0 [bluetooth] stack backtrace: Pid: 1018, comm: kworker/u:1H Not tainted 3.8.0-rc1+ #7 Call Trace: [<ffffffff813e92f9>] print_circular_bug+0x1fb/0x20c [<ffffffff81082215>] __lock_acquire+0x1465/0x1c70 [<ffffffff81083011>] lock_acquire+0xb1/0xe0 [<ffffffffa0033ba6>] ? sco_chan_del+0x66/0x190 [bluetooth] [<ffffffff813efd01>] _raw_spin_lock+0x41/0x80 [<ffffffffa0033ba6>] ? sco_chan_del+0x66/0x190 [bluetooth] [<ffffffffa0033ba6>] sco_chan_del+0x66/0x190 [bluetooth] [<ffffffffa0033d6d>] sco_conn_del+0x9d/0xe0 [bluetooth] [<ffffffffa0034653>] sco_disconn_cfm+0x53/0x60 [bluetooth] [<ffffffffa000fef3>] hci_disconn_complete_evt.isra.54+0x363/0x3c0 [bluetooth] [<ffffffffa000fbd0>] ? hci_disconn_complete_evt.isra.54+0x40/0x3c0 [bluetooth] [<ffffffffa00150f7>] hci_event_packet+0xc7/0x29b0 [bluetooth] [<ffffffff81202e90>] ? __dynamic_pr_debug+0x80/0x90 [<ffffffff8133ff7d>] ? kfree_skb+0x2d/0x40 [<ffffffffa0021644>] ? hci_send_to_monitor+0x1a4/0x1c0 [bluetooth] [<ffffffffa0004583>] hci_rx_work+0x133/0x870 [bluetooth] [<ffffffff8104d5f8>] ? process_one_work+0x258/0x4f0 [<ffffffff8104d65f>] process_one_work+0x2bf/0x4f0 [<ffffffff8104d5f8>] ? process_one_work+0x258/0x4f0 [<ffffffff8104fdc1>] ? worker_thread+0x51/0x3e0 [<ffffffffa0004450>] ? hci_tx_work+0x800/0x800 [bluetooth] [<ffffffff81050022>] worker_thread+0x2b2/0x3e0 [<ffffffff8104fd70>] ? busy_worker_rebind_fn+0x100/0x100 [<ffffffff81056021>] kthread+0xd1/0xe0 [<ffffffff81055f50>] ? flush_kthread_worker+0xc0/0xc0 [<ffffffff813f14bc>] ret_from_fork+0x7c/0xb0 [<ffffffff81055f50>] ? flush_kthread_worker+0xc0/0xc0 Signed-off-by: -

If a controller is powered on while the HCI_AUTO_OFF flag is set the link security setting (HCI_LINK_SECURITY) might not be in sync with the actual state of the controller (HCI_AUTH).

We will need to create three separate UUID lists in the EIR data (for 16, 32 and 128 bit UUIDs) so the code is easier to follow if each list is generated in their own function. Signed-off-by:

Johan Hedberg authored
The primary purpose of the UUIDs is to enable generation of EIR and AD data. In these data formats the UUIDs are split into separate fields based on whether they're 16, 32 or 128 bit UUIDs. To make the generation of these data fields simpler this patch adds a type member to the bt_uuid struct and assigns a value to it as soon as the UUID is added to the kernel. This way the type doesn't need to be calculated each time the UUID list is later iterated. Signed-off-by:

We should be encoding UUIDs to the EIR data in the same order that they were added to the kernel, i.e. each UUID should be added to the end of the UUIDs list. This patch fixes the issue by using list_add_tail instead of list_add for storing the UUIDs. Signed-off-by:
