2009-12-03Bluetooth: Fix miscdev ops owner for virtual driverMarcel Holtmann
The /dev/vhci ops don't refer to the module and so it is possible to unload the module while the file descriptor is in use. This was an accidental removal after the cleanup. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2009-11-28pcmcia: rework the irq_req_t typedefDominik Brodowski
Most of the irq_req_t typedef'd struct can be re-worked quite easily: (1) IRQInfo2 was unused in any case, so drop it. (2) IRQInfo1 was used write-only, so drop it. (3) Instance (private data to be passed to the IRQ handler): Most PCMCIA drivers using pcmcia_request_irq() to actually register an IRQ handler set the "dev_id" to the same pointer as the "priv" pointer in struct pcmcia_device. Modify the two exceptions (ipwireless, ibmtr_cs) to also work this waym and set the IRQ handler's "dev_id" to p_dev->priv unconditionally. (4) Handler is to be of type irq_handler_t. (5) Handler != NULL already tells whether an IRQ handler is present. Therefore, we do not need the IRQ_HANDLER_PRESENT flag in irq_req_t.Attributes.

2009-11-11btusb bluetooth driver: wait for 'waker' work too before closingLinus Torvalds
Rafael debugged a resume-time hang (with oopses in workqueue handling) on his laptop that was due to the 'waker' workqueue entry being disconnected and then released without the workqueue entry having been synchronized. Several people were involved, with Oleg Nesterov doing a debugging patch showing what workqueue entry was corrupt etc. This was a regression introduced by commit 7bee549e19 ("Bluetooth: Add USB autosuspend support to btusb driver") as Rafael points out (not actually bisected, but it became clear once the bug was found).

2009-08-24Bluetooth: Add USB autosuspend support to btusb driverOliver Neukum
This patch adds support of USB autosuspend to the btusb driver. If the device doesn't support remote wakeup, simple support based on up/down is provided. If the device supports remote wakeup, additional support for autosuspend while the interface is up is provided. This is done by queueing URBs in an anchor structure and waking the device up from a work queue on sending. Reception triggers remote wakeup. The last busy facility of the USB autosuspend code is used. To close a race between autosuspend and transmission, a counter of ongoing transmissions is maintained. Add #ifdefs for CONFIG_PM as necessary. Signed-off-by: Oliver Neukum <oliver@neukum.org> Tested-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2009-08-22Bluetooth: Remove Enter/Leave debug statements from Marvell driverMarcel Holtmann

2009-08-22Bluetooth: Remove private device name of Marvell SDIO driverMarcel Holtmann

2009-08-22Bluetooth: Fix Kconfig for Marvell Bluetooth driverMarcel Holtmann
The Marvell driver selects DEBUG_FS and FW_LOADER for its core driver and that is pointless. Don't select DEBUG_FS since it is either enabled or not and it is not for the driver to enable it.

2009-06-11tty: fix bluetooth scribbling on low latency flagsAlan Cox

2009-06-11tty: rewrite the ldisc lockingAlan Cox
There are several pretty much unfixable races in the old ldisc code, especially with respect to pty behaviour and also to hangup. It's easier to rewrite the code than simply try and patch it up. This patch - splits the ldisc from the tty (so we will be able to refcount it more cleanly later) - introduces a mutex lock for ldisc changing on an active device - fixes the complete mess that hangup caused - implements hopefully correct setldisc/close/hangup locking There are still some problems around pty pairs that have always been there but at least it is now possible to understand the code and fix further problems. This fixes the following known bugs - hang up can leak ldisc references - hang up may not call open/close on ldisc in a matched way - pty/tty pairs can deadlock during an ldisc change - reading the ldisc proc files can cause every ldisc to be loaded and probably a few other of the mysterious ldisc race reports. I'm sure it also adds the odd new one. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-06-08Bluetooth: Remove unused and unneeded support in virtual driverMarcel Holtmann

2009-02-27Bluetooth: Submit bulk URBs along with interrupt URBsMarcel Holtmann
Submitting the bulk URBs for ACL data transfers only on demand has no real benefit compared to just submit them when a Bluetooth device gets opened. So when submitting the interrupt URBs for HCI events, just submit the bulk URBs, too. This solves a problem with some Bluetooth USB dongles that has been reported over the last few month. These devices require that the bulk URBs are actually present. These devices are really broken, but there is nothing we can do about it. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2008-11-30Bluetooth: Send HCI Reset command by default on device initializationMarcel Holtmann
The Bluetooth subsystem was not using the HCI Reset command when doing device initialization. The Bluetooth 1.0b specification was ambiguous on how the device firmware was suppose to handle it. Almost every device was triggering a transport reset at the same time. In case of USB this ended up in disconnects from the bus. All modern Bluetooth dongles handle this perfectly fine and a lot of them actually require that HCI Reset is sent. If not then they are either stuck in their HID Proxy mode or their internal structures for inquiry and paging are not correctly setup. To handle old and new devices smoothly the Bluetooth subsystem contains a quirk to force the HCI Reset on initialization. However maintaining such a quirk becomes more and more complicated. This patch turns the logic around and lets the old devices disable the HCI Reset command. The only device where the HCI_QUIRK_NO_RESET is still needed are the original Digianswer devices and dongles with an early CSR firmware. CSR reported that they fixed this for version 12 firmware. The last official release of version 11 firmware is build ID 115. The first version 12 candidate was build ID 117. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
