ad1bd92a49d78df6bc6e75bee68c517c1326f3cf 08-Jan-2016 Eric Laurent <elaurent@google.com> fix possible overflow in effect wrappers.

Add checks on parameter size field in effect command handlers
to avoid overflow leading to invalid comparison with min allowed
size for command and reply buffers.

Bug: 26347509.

Changes include:

[x] In get parameter series of functions, replaced size_t*
formal parameter type with uint32_t* where actual parameter
passed was uint32_t*.

[x] In set parameter series of functions, changed size_t
formal parameter to uint32_t where actual parameter was

[x] Changed the definition of LVM_UINT32 from unsigned
long to uint32_t as unsigned long is 64-bit in LP64.

[x] Used other stdint.h types for other LVM_types for

[x] Use of uintptr_t for the pNextMember of the INST_ALLOC
structure, rather than LVM_UINT32, for portablility.

[x] Use of uintptr_t where pointers are used in arithmetic.

[x] Replaced the use of 0xFFFFFFFC with ~3 in places where
it was used to clear last two bits.

[x] Removed int casts where cmdSize and *replySize, both
uint32_t, were being compared with sizeof().

5875516ea11f77438f2ed23334fc490a706edd56 02-May-2013 Eric Laurent <elaurent@google.com> Fix reverb at 48kHz

The LVM reverb wrapper had a test to only accept input
sampling rate of 44.1 kHz. As the LVM reberb engine
supports multiple sampling rate we can remove this test.

The fix for issue 8512027 (commit 2a9c5cd4) caused a regression
because the framework now checks the return code of the effect
configure command and ignores subsequent commands in case of error.

The effects libraries were exporting many more symbols than needed.
This reduces the exported symbols to just the needed ones (basically
just "AELI"), which happens to also save about 28KB.

Renamed audio effect library interface command for audio format
This makes the naming more consistent with other exixsting commands
and allow adding a new command to get the configuration (EFFECT_CMD_GET_CONFIG).
Same change for reverse channel configuration renamed from

Implemented EFFECT_CMD_GET_CONFIG in exisitng effect libraries.

Moved and renamed media/EffectApi.h to hardware/audio_effect.h
Modified the effect library API to expose a library info structure
containing an interface functions table.
Also removed enums for audio channels, audio format and devices
from effect API and use values from system/audio.h instead.

Modified effects factory to support new library interface format and
load libraries and efffects listed in audio_effects.conf file.
The file audio_effects.conf is first loaded from /vendor/etc and
then from /system/etc/audio_effects.conf if not found.

Modified existing effect libraries to implement the new library interface.

the default value of MEDIUMROOM. Corrected default value to match the

e0aed6ddcb4e3c301b80aa26706b6052dab42c41 11-Sep-2010 Eric Laurent <elaurent@google.com> Fix volume problems with insert revert

- Use a constant input level to the reverb engine and implement volume control in the
insert reverb. This avoids the volume spikes when an effect that was inserted after
the reverb is disabled or removed.
- Fix clicks (one silent buffer) at the end of the reverb disable period.
- Modified volume management in audioflinger so that the volume ramp is also done by
the insert effect if present when the track is paused (avoids clicks).
- Increased room level for all presets.

Also fixed problems with output stage session (-1):
- effect bundle wrapper was not designed to support session -1
- the permission check in audioflinger for using session -1 failed due to a wrong usage of
