2013-02-04net: remove redundant check for timer pending state before del_timerYing Xue1-2/+2
As in del_timer() there has already placed a timer_pending() function to check whether the timer to be deleted is pending or not, it's unnecessary to check timer pending state again before del_timer() is called.

2013-02-01Bluetooth: Reduce critical section in sco_conn_readyAndre Guedes1-8/+10
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: Andre Guedes <[email protected]> Signed-off-by: Gustavo Padovan <[email protected]>

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).

2013-02-01Bluetooth: Keep track of UUID type upon additionJohan Hedberg1-25/+23
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.

2013-02-01Bluetooth: Store UUIDs in the same order that they were addedJohan Hedberg1-1/+1
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.

If occurs a LE or SCO hci_conn timeout and the connection is already established (BT_CONNECTED state), the connection is not terminated as expected. This bug can be reproduced using l2test or scotest tool. Once the connection is established, kill l2test/scotest and the connection won't be terminated.

2013-01-31Bluetooth: Fix handling of unexpected SMP PDUsJohan Hedberg1-0/+13
The conn->smp_chan pointer can be NULL if SMP PDUs arrive at unexpected moments. To avoid NULL pointer dereferences the code should be checking for this and disconnect if an unexpected SMP PDU arrives. This patch fixes the issue by adding a check for conn->smp_chan for all other PDUs except pairing request and security request (which are are the first PDUs to come to initialize the SMP context).

2013-01-18tty: Added a CONFIG_TTY option to allow removal of TTYJoe Millenbach1-0/+1
The option allows you to remove TTY and compile without errors. This saves space on systems that won't support TTY interfaces anyway. bloat-o-meter output is below. The bulk of this patch consists of Kconfig changes adding "depends on TTY" to various serial devices and similar drivers that require the TTY layer. Ideally, these dependencies would occur on a common intermediate symbol such as SERIO, but most drivers "select SERIO" rather than "depends on SERIO", and "select" does not respect dependencies. bloat-o-meter output comparing our previous minimal to new minimal by removing TTY.

There's a per-HCI device workqueue (hdev->workqueue) that should be used for general per-HCI device work (except hdev->req_workqueue that's for hci_request() related work).

2013-01-18Bluetooth: Add a new workqueue for hci_request operationsJohan Hedberg1-0/+11
The hci_request function is blocking and cannot be called through the usual per-HCI device workqueue (hdev->workqueue). While hci_request is in progress any other work from the queue, including sending HCI commands to the controller would be blocked and eventually cause the hci_request call to time out.

2013-01-15TTY: switch tty_flip_buffer_pushJiri Slaby1-11/+5
Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. Now, the one where most of tty_port_tty_get gets removed: tty_flip_buffer_push. IOW we also closed all the races in drivers not using tty_port_tty_get at all yet. Also we move tty_flip_buffer_push declaration from include/linux/tty.h to include/linux/tty_flip.h to all others while we are changing it anyway.

2013-01-10Bluetooth: Fix sending incorrect new_settings for mgmt_set_poweredJohan Hedberg1-2/+3
The socket from which a mgmt_set_powered command was received should only receive the command response but no new_settings event. The mgmt_powered() function which is used to handle the situation with the HCI_AUTO_OFF flag tries to check for a pending command to know which socket to skip the event for, but since the pending command hasn't been added this will not happen. This patch fixes the issue by adding the pending command for the HCI_AUTO_OFF case and thereby ensures that mgmt_powered() will skip the right socket when sending the new_settings event, but still send the proper response to the socket where the command came from.

2013-01-10Bluetooth: Fix checking for exact values of boolean mgmt parametersJohan Hedberg1-0/+36
All mgmt_set_* commands that take a boolean value encoded in the form of a byte should only accept the values 0x00 and 0x01. This patch adds the necessary checks for this and returns "invalid params" responses if anything else is provided as the value.

2013-01-10Bluetooth: Move non-critical sections outside of the dev lockJohan Hedberg1-28/+18
This patch fixes sections of code that do not need hci_lock_dev to be outside of the lock. Such sections include code that do not touch the hdev at all as well as sections which just read a single byte from the supported_features value (i.e. all lmp_*_capable() macros).

2013-01-10Bluetooth: Fix accepting set_dev_class for non-BR/EDR controllersJohan Hedberg1-0/+6
The concept of Class of Device only exists for BR/EDR controllers. The mgmt_set_dev_class command should therefore return a proper "not supported" error if it is attempted for a controller that doesn't support BR/EDR (e.g. a single mode LE-only one).

2013-01-10Bluetooth: Fix checking for valid device class valuesJohan Hedberg1-0/+6
The two lowest bits of the minor device class value are reserved and should be zero, and the three highest bits of the major device class likewise. The management code should therefore test for this and return a proper "invalid params" error if the condition is not met.

2013-01-10Bluetooth: Fix missing command complete for mgmt_load_long_term_keysJohan Hedberg1-2/+5
All management events are expected to indicate successful completion through a command complete event, however the load long term keys command was missing this. This patch adds the missing event.
