  • d632eb1bf   USB: convert drivers/net/* to use module_usb_driver() ... Browse Code »

    This converts the drivers in drivers/net/* to use the
    module_usb_driver() macro which makes the code smaller and a bit
    simpler.

    Added bonus is that it removes some unneeded kernel log messages about
    drivers loading and/or unloading.

    Fix up IRDA drivers that return an errno value to qdisc_restart(), causing
    qdisc_restart() to print a warning an requeue/retransmit the skb.

    - donauboe: intention appears to be to have the skb retransmitted without
    error message
    - irda-usb: intention is to drop silently according to comment
    - kingsub-sir: skb is freed: use after free
    - ks959-sir: skb is freed: use after free
    - ksdazzle-sir: skb is freed: use after free
    - mcs7880: skb is freed: use after free

    All but donauboe compile tested.

  • 4cf1653aa   netdevice: safe convert to netdev_priv() #part-2 ... Browse Code »

    We have some reasons to kill netdev->priv:
    1. netdev->priv is equal to netdev_priv().
    2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
    netdev_priv() is more flexible than netdev->priv.
    But we cann't kill netdev->priv, because so many drivers reference to it
    directly.

    This patch is a safe convert for netdev->priv to netdev_priv(netdev).
    Since all of the netdev->priv is only for read.
    But it is too big to be sent in one mail.
    I split it to 4 parts and make every part smaller than 100,000 bytes,
    which is max size allowed by vger.

    And then go through and reinstate those cases where code is casting pointers

    And then drop a few hunks which conflicted with outstanding work.

  • 7d12e780e   IRQ: Maintain regs pointer globally rather than passing to IRQ handlers ... Browse Code »

    Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
    of passing regs around manually through all ~1800 interrupt handlers in the
    Linux kernel.

    The regs pointer is used in few places, but it potentially costs both stack
    space and code to pass it around. On the FRV arch, removing the regs parameter
    from all the genirq function results in a 20% speed up of the IRQ exit path
    (ie: from leaving timer_interrupt() to leaving do_IRQ()).

    Where appropriate, an arch may override the generic storage facility and do
    something different with the variable. On FRV, for instance, the address is
    maintained in GR28 at all times inside the kernel as part of general exception
    handling.

    Having looked over the code, it appears that the parameter may be handed down
    through up to twenty or so layers of functions. Consider a USB character
    device attached to a USB hub, attached to a USB controller that posts its
    interrupts through a cascaded auxiliary interrupt controller. A character
    device driver may want to pass regs to the sysrq handler through the input
    layer which adds another few layers of parameter passing.

    I've build this code with allyesconfig for x86_64 and i386. I've runtested the
    main part of the code on FRV and i386, though I can't test most of the drivers.
    I've also done partial conversion for powerpc and MIPS - these at least compile
    with minimal configurations.

    This will affect all archs. Mostly the changes should be relatively easy.
    Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

    struct pt_regs *old_regs = set_irq_regs(regs);

    And put the old one back at the end:

    set_irq_regs(old_regs);

    Don't pass regs through to generic_handle_irq() or __do_IRQ().

    In timer_interrupt(), this sort of change will be necessary:

    - update_process_times(user_mode(regs));
    - profile_tick(CPU_PROFILING, regs);
    + update_process_times(user_mode(get_irq_regs()));
    + profile_tick(CPU_PROFILING);

    I'd like to move update_process_times()'s use of get_irq_regs() into itself,
    except that i386, alone of the archs, uses something other than user_mode().

    Some notes on the interrupt handling in the drivers:

    (*) input_dev() is now gone entirely. The regs pointer is no longer stored in
    the input_dev struct.

    (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
    something different depending on whether it's been supplied with a regs
    pointer or not.

    (*) Various IRQ handler function pointers have been moved to type
    irq_handler_t.

  • 38e2bfc94   USB: Dealias -110 code (more complete) ... Browse Code »

    The purpose of this patch is to split off the case when a device does
    not reply on the lower level (which is reported by HC hardware), and
    a case when the device accepted the request, but does not reply at
    upper level. This redefinition allows to diagnose issues easier,
    without asking the user if the -110 happened "immediately".

    The usbmon splits such cases already thanks to its timestamp, but
    it's not always available.

    I adjusted all drivers which I found affected (by searching for "urb").
    Out of tree drivers may suffer a little bit, but I do not expect much
    breakage. At worst they may print a few messages.

  • 669d32a29   [IRDA]: irda-usb bug fixes ... Browse Code »

    This patch fixes 2 bugs in the USB-IrDA code.

    The first one is a buffer overrun in the RX path. We are now using
    IRDA_SKB_MAX_MTU when initializing the Rx URB.

    The second one is a potential stack recursion when unplugging the USB
    dongle. It seems that first we get the Rx URB with a generic error
    code, and after a while the Rx URB comes again with a "disconnect"
    error code. Since we are resubmitting the Rx URB immediately after
    receiving the first error one, we might enter an endless loop.

    When getting an error Rx URB, the patch defers the Rx URB resubmitting
    so that it gives us a chance to catch the disconnect one, in case the
    dongle has juts been unplugged.

    Tested against 2.6.16-rc2.
