* Bluetooth: Introduce a flags variable to Three-wire UART stateJohan Hedberg2012-07-171-11/+15
| | | | | | | | This patch introduces a flags variable to the Three-wire UART state struct and converts the two existing bools in the struct into flags. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk>
* Bluetooth: Improve Three-wire UART configuration handlingJohan Hedberg2012-07-171-7/+27
| | | | | | | | | | | The configuration request/response messages contain a configuration field which contains the sliding window size (amount of unacked reliable packets that can be pending). This patch makes sure that we configure the correct size (minimum of local and remote values) and use it when determining whether to send new packets or not.

* Bluetooth: Remove unnecessary h5_build_pkt functionJohan Hedberg2012-07-171-26/+23
| | | | | | | | | The implementation of h5_build_packet can be moved into h5_prepare_pkt since all h5_prepare_pkt does is determine whether the packet is reliable and then call h5_build_packet.

* Bluetooth: Implement proper low-power support for Three-wire UARTJohan Hedberg2012-07-171-5/+32
| | | | | | | | | | | | This patch adds on-demand wakeup request sending (and re-sendind) when we are in low-power state. When the controller enters this state it will send a sleep message after which the host is not allowed to send any other packets until a wakeup request has been sent and the woken message received as a response to it. The wakeup requests are re-sent periodically until a woken message is received. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk>
* Bluetooth: Add initialization tracking to HCI Three-wire driverJohan Hedberg2012-07-171-16/+50
| | | | | | | | | | | This patch adds tracking for the uninitialized, initialized and active states for Three-wire UART. This is needed so we can handle periodic sending of the Link Establishment messages before reaching active state and so that we do not try to do any higher level HCI data transmission before reaching active state.

* Bluetooth: Add initial sleep support to Three-wire UARTJohan Hedberg2012-07-171-0/+13
| | | | | | | | | | This patch adds very basic support for the sleep related messages. The only thing the code does right now is send a wakeup message as soon as receiving a sleep one, essentially preventing the controller from going to sleep.

* Bluetooth: Add delayed init sequence support for UART controllersJohan Hedberg2012-07-172-1/+43
| | | | | | | | | | This patch makes it possible to have UART drivers perform an internal initialization before calling hci_register_dev. This allows moving a lot of init code from user space (hciattach) to the kernel side, thereby creating a more controlled/robust initialization process.

John was just away on a trip and didn't have a change to send the pull request until a day or two ago. 2) Put back some defines in user exposed header file areas that were removed during the tokenring purge. From Stephen Hemminger and Paul Gortmaker. 3) A bug fix for UDP hash table allocation got lost in the pile due to one of those "you got it.. no I've got it.." situations. :-) From Tim Bird. 4) SKB coalescing in TCP needs to have stricter checks, otherwise we'll try to coalesce overlapping frags and crash.

The possible values for the alternate setting are described in the Bluetooth Core Specification, Volume 4, Part B, section 2.1.1.

| * Bluetooth: vhci: Ignore return code of nonseekable_open()David Herrmann2012-05-091-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The comment in ./fs/open.c clearly states that nonseekable_open() will never fail. Therefore, we can safely ignore the return code. This is the recommended way to deal with nonseekable_open(). Our current code looks like nonseekable_open() is checked for the return code. However, if we check the return code, we must also kfree() our private data if the open fails. To avoid this overhead and to avoid confusion, we simply drop the return code and return 0.

| * Bluetooth: Remove redundant hdev->parent fieldDavid Herrmann2012-05-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We initialize the "struct device" in hci_alloc_dev() for a long time now so we can access hdev->dev.parent directly. Hence, we can drop the temporary field hdev->parent which is used in no other place than hci_add_sysfs(). SET_HCIDEV_DEV() is never called after registering a device by the drivers so we do not overwrite internal device-state. Furthermore, hdev->dev is initialized to 0 by kzalloc() inside hci_alloc_dev() so the default behavior with dev.parent = NULL is kept.

* | USB: Disable hub-initiated LPM for comms devices.Sarah Sharp2012-05-185-0/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hub-initiated LPM is not good for USB communications devices. Comms devices should be able to tell when their link can go into a lower power state, because they know when an incoming transmission is finished. Ideally, these devices would slam their links into a lower power state, using the device-initiated LPM, after finishing the last packet of their data transfer. If we enable the idle timeouts for the parent hubs to enable hub-initiated LPM, we will get a lot of useless LPM packets on the bus as the devices reject LPM transitions when they're in the middle of receiving data. Worse, some devices might blindly accept the hub-initiated LPM and power down their radios while they're in the middle of receiving a transmission. The Intel Windows folks are disabling hub-initiated LPM for all USB communications devices under a xHCI USB 3.0 host. In order to keep the Linux behavior as close as possible to Windows, we need to do the same in Linux. Set the disable_hub_initiated_lpm flag for for all USB communications drivers. I know there aren't currently any USB 3.0 devices that implement these class specifications, but we should be ready if they do.

This fixes a race between tty_close and hci_dev_open which can result in a NULL-pointer dereference. The line discipline closes the protocol driver while we may still have hci_dev_open sleeping on the req_lock mutex resulting in a NULL-pointer dereference when lock is acquired and hci_init_req called. Bug is 100% reproducible using hciattach and a disconnected serial port: 0. # hciattach -n ttyO1 any noflow 1. hci_dev_open called from hci_power_on grabs req lock 2. hci_init_req executes but device fails to initialise (times out eventually) 3. hci_dev_open is called from hci_sock_ioctl and sleeps on req lock 4. hci_uart_tty_close detaches protocol driver and cancels init req 5. hci_dev_open (1) releases req lock 6. hci_dev_open (3) grabs req lock, calls hci_init_req, which triggers oops when request is prepared in hci_uart_send_frame [ 137.201263] Unable to handle kernel NULL pointer dereference at virtual address 00000028 [ 137.209838] pgd = c0004000 [ 137.212677] [00000028] *pgd=00000000 [ 137.216430] Internal error: Oops: 17 [#1] [ 137.220642] Modules linked in: [ 137.223846] CPU: 0 Tainted: G W (3.3.0-rc6-dirty #406) [ 137.230529] PC is at __lock_acquire+0x5c/0x1ab0 [ 137.235290] LR is at lock_acquire+0x9c/0x128 [ 137.239776] pc : [<c0071490>] lr : [<c00733f8>] psr: 20000093 [ 137.239776] sp : cf869dd8 ip : c0529554 fp : c051c730 [ 137.251800] r10: 00000000 r9 : cf8673c0 r8 : 00000080 [ 137.257293] r7 : 00000028 r6 : 00000002 r5 : 00000000 r4 : c053fd70 [ 137.264129] r3 : 00000000 r2 : 00000000 r1 : 00000000 r0 : 00000001 [ 137.270965] Flags: nzCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment kernel [ 137.278717] Control: 10c5387d Table: 8f0f4019 DAC: 00000015 [ 137.284729] Process kworker/u:1 (pid: 7, stack limit = 0xcf8682e8) [ 137.291229] Stack: (0xcf869dd8 to 0xcf86a000) [ 137.295776] 9dc0: c0529554 00000000 [ 137.304351] 9de0: cf8673c0 cf868000 d03ea1ef cf868000 000001ef 00000470 00000000 00000002 [ 137.312927] 9e00: cf8673c0 00000001 c051c730 c00716ec 0000000c 00000440 c0529554 00000001 [ 137.321533] 9e20: c051c730 cf868000 d03ea1f3 00000000 c053b978 00000000 00000028 cf868000 [ 137.330078] 9e40: 00000000 00000000 00000002 00000000 00000000 c00733f8 00000002 00000080 [ 137.338684] 9e60: 00000000 c02a1d50 00000000 00000001 60000013 c0969a1c 60000093 c053b96c [ 137.347259] 9e80: 00000002 00000018 20000013 c02a1d50 cf0ac000 00000000 00000002 cf868000 [ 137.355834] 9ea0: 00000089 c0374130 00000002 00000000 c02a1d50 cf0ac000 0000000c cf0fc540 [ 137.364410] 9ec0: 00000018 c02a1d50 cf0fc540 00000000 cf0fc540 c0282238 c028220c cf178d80 [ 137.372985] 9ee0: 127525d8 c02821cc 9a1fa451 c032727c 9a1fa451 127525d8 cf0fc540 cf0ac4ec [ 137.381561] 9f00: cf0ac000 cf0fc540 cf0ac584 c03285f4 c0328580 cf0ac4ec cf85c740 c05510cc [ 137.390136] 9f20: ce825400 c004c914 00000002 00000000 c004c884 ce8254f5 cf869f48 00000000 [ 137.398712] 9f40: c0328580 ce825415 c0a7f914 c061af64 00000000 c048cf3c cf8673c0 cf85c740 [ 137.407287] 9f60: c05510cc c051a66c c05510ec c05510c4 cf85c750 cf868000 00000089 c004d6ac [ 137.415863] 9f80: 00000000 c0073d14 00000001 cf853ed8 cf85c740 c004d558 00000013 00000000 [ 137.424438] 9fa0: 00000000 00000000 00000000 c00516b0 00000000 00000000 cf85c740 00000000 [ 137.433013] 9fc0: 00000001 dead4ead ffffffff ffffffff c0551674 00000000 00000000 c0450aa4 [ 137.441589] 9fe0: cf869fe0 cf869fe0 cf853ed8 c005162c c0013b30 c0013b30 00ffff00 00ffff00 [ 137.450164] [<c0071490>] (__lock_acquire+0x5c/0x1ab0) from [<c00733f8>] (lock_acquire+0x9c/0x128) [ 137.459503] [<c00733f8>] (lock_acquire+0x9c/0x128) from [<c0374130>] (_raw_spin_lock_irqsave+0x44/0x58) [ 137.469360] [<c0374130>] (_raw_spin_lock_irqsave+0x44/0x58) from [<c02a1d50>] (skb_queue_tail+0x18/0x48) [ 137.479339] [<c02a1d50>] (skb_queue_tail+0x18/0x48) from [<c0282238>] (h4_enqueue+0x2c/0x34) [ 137.488189] [<c0282238>] (h4_enqueue+0x2c/0x34) from [<c02821cc>] (hci_uart_send_frame+0x34/0x68) [ 137.497497] [<c02821cc>] (hci_uart_send_frame+0x34/0x68) from [<c032727c>] (hci_send_frame+0x50/0x88) [ 137.507171] [<c032727c>] (hci_send_frame+0x50/0x88) from [<c03285f4>] (hci_cmd_work+0x74/0xd4) [ 137.516204] [<c03285f4>] (hci_cmd_work+0x74/0xd4) from [<c004c914>] (process_one_work+0x1a0/0x4ec) [ 137.525604] [<c004c914>] (process_one_work+0x1a0/0x4ec) from [<c004d6ac>] (worker_thread+0x154/0x344) [ 137.535278] [<c004d6ac>] (worker_thread+0x154/0x344) from [<c00516b0>] (kthread+0x84/0x90) [ 137.543975] [<c00516b0>] (kthread+0x84/0x90) from [<c0013b30>] (kernel_thread_exit+0x0/0x8) [ 137.552734] Code: e59f4e5c e5941000 e3510000 0a000031 (e5971000) [ 137.559234] ---[ end trace 1b75b31a2719ed1e ]--- Cc: stable <stable@vger.kernel.org> Signed-off-by: Johan Hovold <jhovold@gmail.com> Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
