    snd_seq_timer_open() didn't catch the whole error path but let through
    if the timer id is a slave. This may lead to Oops by accessing the
    uninitialized pointer.

  • 2069d483b   ALSA: vmaster: Fix slave change notification ... Browse Code »

    When a value of a vmaster slave control is changed, the ctl change
    notification is sometimes ignored. This happens when the master
    control overrides, e.g. when the corresponding master control is
    muted. The reason is that slave_put() returns the value of the actual
    slave put callback, and it doesn't reflect the virtual slave value
    change.

    This patch fixes the function just to return 1 whenever a slave value
    is changed.

  • 85c50a589   ALSA: seq: seq_oss_event: missing range checks ... Browse Code »

    The "dev" variable could be out of bounds. Calling
    snd_seq_oss_synth_is_valid() checks that it is is a valid device
    which has been opened. We check this inside set_note_event() so
    this function can't succeed without a valid "dev". But we need to
    do the check earlier to prevent invalid dereferences and memory
    corruption.

    One call tree where "dev" could be out of bounds is:
    -> snd_seq_oss_oob_user()
    -> snd_seq_oss_process_event()
    -> extended_event()
    -> note_on_event()

  • 17ac8e5c6   ALSA: core: don't return uninitialized snd_compr_tstamp ... Browse Code »

    The snd_compr_update_tstamp() can only fill in the snd_compr_tstamp
    if the codec implements the pointer() function. If that happened
    the code was previously returning uninitialized garbage in the
    tstamp because it wasn't initialized anywhere.

    This change zero-fills the tstamp in the two places it is used
    before calling snd_compr_update_tstamp(), and also has
    snd_compr_update_tstamp() return an error indication if it
    can't provide a tstamp. For the case of snd_compr_calc_avail()
    it ignores this error because we still need to return info on
    the available buffer space even if we can't provide tstamp
    info - when the tstamp is not valid all fields are now
    guaranteed to be zero.

  • 9c7066aef   ALSA: core: fix 64-bit SNDRV_PCM_IOCTL_STATUS ABI breakage ... Browse Code »

    Commit 4eeaaeaea (ALSA: core: add hooks for audio timestamps) added the
    new audio_tstamp field to struct snd_pcm_status. However, struct
    timespec requires 64-bit alignment, so the 64-bit compiler would insert
    32 bits of padding before this field, which broke SNDRV_PCM_IOCTL_STATUS
    with error messages like this:

    kernel: unknown ioctl = 0x80984120

    To solve this, insert the padding explicitly so that it can be taken
    into account when calculating the ABI structure size.

  • 4eeaaeaea   ALSA: core: add hooks for audio timestamps ... Browse Code »

    ALSA did not provide any direct means to infer the audio time for A/V
    sync and system/audio time correlations (eg. PulseAudio).
    Applications had to track the number of samples read/written and
    add/subtract the number of samples queued in the ring buffer. This
    accounting led to small errors, typically several samples, due to the
    two-step process. Computing the audio time in the kernel is more
    direct, as all the information is available in the same routines.

    Also add new .audio_wallclock routine to enable fine-grain synchronization
    between monotonic system time and audio hardware time.
    Using the wallclock, if supported in hardware, allows for a
    much better sub-microsecond precision and a common drift tracking for
    all devices sharing the same wall clock (master clock).

  • 314e51b98   mm: kill vma flag VM_RESERVED and mm->reserved_vm counter ... Browse Code »

    A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA,
    currently it lost original meaning but still has some effects:

    | effect | alternative flags
    -+------------------------+---------------------------------------------
    1| account as reserved_vm | VM_IO
    2| skip in core dump | VM_IO, VM_DONTDUMP
    3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP
    4| do not mlock | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP

    This patch removes reserved_vm counter from mm_struct. Seems like nobody
    cares about it, it does not exported into userspace directly, it only
    reduces total_vm showed in proc.

    Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP.

    remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP.
    remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.

    Pull sound updates from Takashi Iwai:
    "This contains pretty many small commits covering fairly large range of
    files in sound/ directory. Partly because of additional API support
    and partly because of constantly developed ASoC and ARM stuff.

    Some highlights:

    - Introduced the helper function and documentation for exposing the
    channel map via control API, as discussed in Plumbers; most of PCI
    drivers are covered, will follow more drivers later

    - Most of drivers have been replaced with the new PM callbacks (if
    the bus is supported)

    - HD-audio controller got the support of runtime PM and the support
    of D3 clock-stop. Also changing the power_save option in sysfs
    kicks off immediately to enable / disable the power-save mode.

    - Another significant code change in HD-audio is the rewrite of
    firmware loading code. Other than that, most of changes in
    HD-audio are continued cleanups and standardization for the generic
    auto parser and bug fixes (HBR, device-specific fixups), in
    addition to the support of channel-map API.

    - Addition of ASoC bindings for the compressed API, used by the
    mid-x86 drivers.

    - Lots of cleanups and API refreshes for ASoC codec drivers and
    DaVinci.

    - Conversion of OMAP to dmaengine.

    - New machine driver for Wolfson Microelectronics Bells.

    - New CODEC driver for Wolfson Microelectronics WM0010.

    - Enhancements to the ux500 and wm2000 drivers

    - A new driver for DA9055 and the support for regulator bypass mode."
