ALSA: hda - Increase badness for missing multi-io

weak, and the multi-io tends to be skipped for desktop configurations
when no enough DACs are available.  It's because the total badness of
the multi-io becomes often larger than the badness with assigning an
individual DAC to a headphone jack.  This is good for one side, but it
seems that the surround outputs are more demanded by that.

This patch increases the badness value for the missing multi-io
slightly so that the multi-io would be preferred than the individual
headphone DAC if they conflict.  Through the tests with hda-emu,

ALSA: hda - Fix broken workaround for HDMI/SPDIF conflicts

The commit [dcda58061: ALSA: hda - Add workaround for conflicting
IEC958 controls] introduced a workaround for cards that have both
SPDIF and HDMI devices for giving device=1 to SPDIF control elements.
It turned out, however, that this workaround doesn't work well -

- The workaround checks only conflicts in a single codec, but SPDIF
  and HDMI are provided by multiple codecs in many cases, and

- ALSA mixer abstraction doesn't care about the device number in ctl
  elements, thus you'll get errors from amixer such as
  % amixer scontrols -c 0
  ALSA lib simple_none.c:1551:(simple_add1) helem (MIXER,'IEC958
  Playback Switch',0,1,0) appears twice or more
  amixer: Mixer hw:0 load error: Invalid argument

This patch fixes the previous broken workaround.  Instead of changing
the device number of SPDIF ctl elements, shift the element indices of
such controls up to 16.  Also, the conflict check is performed over
all codecs found on the bus.

HDMI devices will be put to dev=0,index=0 as before.  Only the
conflicting SPDIF device is moved to a different place.  The new place
of SPDIF device is supposed by the updated alsa-lib HDA-Intel.conf,
respectively.

  Linus is accepting, let's save people from the hastle of having to
  patch v3.8 back into working or use a stable kernel.

  Looking at the diffstat, this really is high value for its size; this
  is miniscule compared to how the -rc6 to tip diffstat currently looks.

  So, four patches in this set:
   - Punit Agrawal reports that the kernel no longer boots on MPCore due
     to a new assumption made in the GIC code which isn't true of
     earlier GIC designs.  This is the biggest change in this set.
   - Punit's boot log also revealed a bunch of WARN_ON() dumps caused by
     the DT-ification of the GIC support without fixing up non-DT
     Realview - which now sees a greater number of interrupts than it
     did before.
   - A fix for the DMA coherent code from Marek which uses the wrong
     check for atomic allocations; this can result in spinlock lockups
     or other nasty effects.
   - A fix from Will, which will affect all Android based platforms if
     not applied (which use the 2G:2G VM split) - this causes

ARM: 7641/1: memory: fix broken mmap by ensuring TASK_UNMAPPED_BASE is aligned

We have received multiple reports of mmap failures when running with a
2:2 vm split. These manifest as either -EINVAL with a non page-aligned
address (ending 0xaaa) or a SEGV, depending on the application. The
issue is commonly observed in children of make, which appears to use
bottom-up mmap (assumedly because it changes the stack rlimit).

Further investigation reveals that this regression was triggered by
394ef6403abc ("mm: use vm_unmapped_area() on arm architecture"), whereby
TASK_UNMAPPED_BASE is no longer page-aligned for bottom-up mmap, causing
get_unmapped_area to choke on misaligned addressed.

This patch fixes the problem by defining TASK_UNMAPPED_BASE in terms of
TASK_SIZE and explicitly aligns the result to 16M, matching the other
end of the heap.

A codec may allow software to hide some unused pin/cvt widgets.

Sometimes BIOS does not enable the hidden widgets properly although they are
needed for the board. Thus the driver need to enable them as a board-specific

ASoC: core: Allow digital mute for capture

Help avoid noise from the power up of the capture path propagating through
into the start of the recording (especially noise caused by the ramp of
microphone biases) by keeping the capture muted until after we've finished
powering things up with DAPM in the same manner we do for playback. This
allows us to take advantage of soft mute support in the hardware more
effectively and is more consistent.

The core code using the existing digital mute operation is updated to take
advantage of this. Some additional cases in the soc-pcm code and suspend
will need separate handling but these are less practically relevant than
the main runtime stream start/stop case.

Rather than refactor the digital mute function in every single driver a
new operation is added for drivers taking advantage of this functionality,
the old operation should be phased out over time.

Some early GIC implementations return zero for the first distributor
CPU routing register.  This means we can't rely on that telling us
which CPU interface we're connected to.  We know that these platforms
implement PPIs for IRQs 29-31 - but we shouldn't assume that these
will always be populated.

So, instead, scan for a non-zero CPU routing register in the first
32 IRQs and use that as our CPU mask.

====================
The Xen netback implementation contains a couple of flaws which can
allow a guest to cause a DoS in the backend domain, potentially
affecting other domains in the system.

CVE-2013-0216 is a failure to sanity check the ring producer/consumer
pointers which can allow a guest to cause netback to loop for an
extended period preventing other work from occurring.

CVE-2013-0217 is a memory leak on an error path which is guest
triggerable.

The following series contains the fixes for these issues, as previously
included in Xen Security Advisory 39:
http://lists.xen.org/archives/html/xen-announce/2013-02/msg00001.html

Changes in v2:
 - Typo and block comment format fixes
 - Added stable Cc

11 years agoxen/netback: shutdown the ring if it contains garbage.
Ian Campbell [Wed, 6 Feb 2013 23:41:35 +0000 (23:41 +0000)]
xen/netback: shutdown the ring if it contains garbage.

A buggy or malicious frontend should not be able to confuse netback.
If we spot anything which is not as it should be then shutdown the
device and don't try to continue with the ring in a potentially
hostile state. Well behaved and non-hostile frontends will not be
penalised.

As well as making the existing checks for such errors fatal also add a
new check that ensures that there isn't an insane number of requests
on the ring (i.e. more than would fit in the ring). If the ring
contains garbage then previously is was possible to loop over this
insane number, getting an error each time and therefore not generating
any more pending requests and therefore not exiting the loop in
xen_netbk_tx_build_gops for an externded period.

Also turn various netdev_dbg calls which no precipitate a fatal error
into netdev_err, they are rate limited because the device is shutdown
afterwards.

This fixes at least one known DoS/softlockup of the backend domain.
