  • f3ac9f737   ALSA: seq: Fix link corruption by event error handling ... Browse Code »

    The sequencer FIFO management has a bug that may lead to a corruption
    (shortage) of the cell linked list. When a sequencer client faces an
    error at the event delivery, it tries to put back the dequeued cell.
    When the first queue was put back, this forgot the tail pointer
    tracking, and the link will be screwed up.

    Although there is no memory corruption, the sequencer client may stall
    forever at exit while flushing the pending FIFO cells in
    snd_seq_pool_done(), as spotted by syzkaller.

    This patch addresses the missing tail pointer tracking at
    snd_seq_fifo_cell_putback(). Also the patch makes sure to clear the
    cell->enxt pointer at snd_seq_fifo_event_in() for avoiding a similar
    mess-up of the FIFO linked list.

    Currently ctxfi driver tries to set only the 64bit DMA mask on 64bit
    architectures, and bails out if it fails. This causes a problem on
    some platforms since the 64bit DMA isn't always guaranteed. We should
    fall back to the default 32bit DMA when 64bit DMA fails.

  • 71321eb3f   ALSA: timer: Reject user params with too small ticks ... Browse Code »

    When a user sets a too small ticks with a fine-grained timer like
    hrtimer, the kernel tries to fire up the timer irq too frequently.
    This may lead to the condensed locks, eventually the kernel spinlock
    lockup with warnings.

    For avoiding such a situation, we define a lower limit of the
    resolution, namely 1ms. When the user passes a too small tick value
    that results in less than that, the kernel returns -EINVAL now.

    "This is the main drm pull request for v4.11.

    Nothing too major, the tinydrm and mmu-less support should make

    Intel grew displayport MST audio support which is hopefully useful to
    people, and FBC is on by default for GEN9+ (so people know where to
    look for regressions). AMDGPU has a lot of fixes that would like new
    firmware files installed for some GPUs.

    Other than that it's pretty scattered all over.

    I may have a follow up pull request as I know BenH has a bunch of AST
    rework and fixes and I'd like to get those in once they've been tested

  • e2810d76c   ALSA: usb-audio: Fix memory leak and corruption in mixer_us16x08.c ... Browse Code »

    There are a few places leaking memory and doing double-free in
    mixer_us16x08.c.

    The driver allocates a usb_mixer_elem_info object at each
    add_new_ctl() call. This has to be freed via kctl->private_free, but
    currently this is done properly only for some controls.

    Also, the driver allocates three external objects (comp_store,
    eq_store, meter_store), and these are referred in elem->private_data
    (it's not kctl->private_data). And these have to be released, but
    there are none doing it. Moreover, these extra objects have to be
    released only once. Thus the release should be done only by the first
    kctl element that refers to it.

    For fixing these, we call either snd_usb_mixer_elem_free() (only for
    kctl->private_data) or elem_private_free() (for both
    kctl->private_data and elem->private_data) via kctl->private_free
    appropriately.

    Last but not least, snd_us16x08_controls_create() may return in the
    middle without releasing the allocated *_store objects due to an
    error. For fixing this, we shuffle the allocation code so that it's
    called just before its reference.
