    smp_mb is enough for ordering memory operations among processors,and mb is
    more expensive than smp_mb for UP machine, so replace it with smp_mb().

  • 5fbcd260c   [Bluetooth] Fix USB disconnect handling of btusb driver ... Browse Code »

    The USB transport specification for Bluetooth splits the ACL and SCO
    handling into two separate interfaces. In Linux it possible to probe
    and disconnect these interfaces independently. So make sure that both
    interfaces are tightly bound together.

    This fixes the suspend regression that some people have expierenced.

  • e8c3c3d22   [Bluetooth] Fix wrong URB handling of btusb driver ... Browse Code »

    The btusb driver contains two typos that result in some buggy behavior,
    but the impact is not immediately visible.

    During initialization the submitting of interrupt URBs might fail and
    then make sure to remove the correct flag and not one of the hci_dev
    flags.

    When closing down the interface make sure to kill the anchor for the
    ISOC URBs and not kill the interrupt URBs twice.

    Also cancel any scheduled work when closing down the interface.

    The newer MacBooks contain a Broadcom based Bluetooth chip and to make
    this work properly, HCI_Reset must be send first. If HCI_Reset is not
    used then a lot of I/O errors show up and its triggers packets from
    non-existent ACL links.

    The Bluetooth entries for the MAINTAINERS file are a little bit too
    much. Consolidate them into two entries. One for Bluetooth drivers and
    another one for the Bluetooth subsystem.

    Also the MODULE_AUTHOR should indicate the current maintainer of the
    module and actually not the original author. Fix all Bluetooth modules
    to provide current maintainer information.

  • 9bfa35fe4   [Bluetooth] Add SCO support to btusb driver ... Browse Code »

    The new generic driver for Bluetooth USB devices was missing proper
    SCO support. The driver now claims the second interface for these USB
    devices to allow the flow of SCO packets. It also handles switching
    of the alternate setting and re-submission of isochronous URBs.

    The btusb driver is now a full replacement for hci_usb and thus the
    experimental tag has been removed and this driver is promoted as
    preferred one.

    Move the line disciplines towards a conventional ->ops arrangement. For
    the moment the actual 'tty_ldisc' struct in the tty is kept as part of
    the tty struct but this can then be changed if it turns out that when it
    all settles down we want to refcount ldiscs separately to the tty.

    Pull the ldisc code out of /proc and put it with our ldisc code.

  • 3611f4d2a   hci_ldisc: fix null pointer deref ... Browse Code »

    Arjan:

    With the help of kerneloops.org I've spotted a nice little interaction
    between the TTY layer and the bluetooth code, however the tty layer is not
    something I'm all too familiar with so I rather ask than brute-force fix the
    code incorrectly.

    The raw details are at:
    http://www.kerneloops.org/search.php?search=uart_flush_buffer

    What happens is that, on closing the bluetooth tty, the tty layer goes
    into the release_dev() function, which first does a bunch of stuff, then
    sets the file->private_data to NULL, does some more stuff and then calls the
    ldisc close function. Which in this case, is hci_uart_tty_close().

    Now, hci_uart_tty_close() calls hci_uart_close() which clears some
    internal bit, and then calls hci_uart_flush()... which calls back to the
    tty layers' uart_flush_buffer() function. (in drivers/bluetooth/hci_tty.c
    around line 194) Which then WARN_ON()'s because that's not allowed/supposed
    to be called this late in the shutdown of the port....

    Should the bluetooth driver even call this flush function at all??

    David:

    This seems to be what happens: Hci_uart_close() flushes using
    hci_uart_flush(). Subsequently, in hci_dev_do_close(), (one step in
    hci_unregister_dev()), hci_uart_flush() is called again. The comment in
    uart_flush_buffer(), relating to the WARN_ON(), indicates you can't flush
    after the port is closed; which sounds reasonable. I think hci_uart_close()
    should set hdev->flush to NULL before returning. Hci_dev_do_close() does
    check for this. The code path is rather involved and I'm not entirely clear
    of all steps, but I think that's what should be done.
