First stage of adding a new dataSpace field for ANativeWindow,
for communicating format- (and endpoint-) dependent information
about graphics buffers. For most formats, dataSpace describes the
color space of the buffer, while format describes the memory layout.
For some formats, the dataSpace may also specify that the buffer
contains depth measurements, encoded images, or other kinds of
information that is not necessarily a simple 2D image.
Rename the existing colorspace enumeration to dataspace, with an added
dataspace for depth, and sRGB gamma-corrected and linear colorspaces.
Add in a definition for Android depth point clouds as a
variable-length list of float-triplet coordinates, as the underlying
layout of buffers with format HAL_PIXEL_FORMAT_BLOB and dataSpace of
HAL_DATASPACE_DEPTH.
Also remove now-unnecessary sRGB HAL graphics formats, and remove the
alias RAW_SENSOR that was left in to ease transition to RAW16.

When a file descriptor is closed before removing it from the
epoll set, it will normally be removed automatically from the
epoll set by the kernel. However if there exists a duplicate
then the original file descriptor may remain in the set and
continue to receive events until all duplicates have been closed.
Unfortunately due to kernel limitations we need to rebuild the epoll
set from scratch because it may contain an old file handle that we are
now unable to remove since its file descriptor is no longer valid.
No such problem would have occurred if we were using the poll system
call instead, but that approach carries others disadvantages.

Added code to protect against situations that may occur when a
Looper callback has the side-effect of closing the file descriptor that
it is watching before it returns. This code pattern is very
convenient for implementation but it does expose issues in how
the list of callbacks is maintained. In particular, we
need to watch out for file descriptors which have been reused.
This change may resolve previously unexplained ANRs associated with
log messages such as: "Error modifying epoll events for fd 44, errno=2"

On 64 bit systems, calls to dump_backtrace_to_file or dump_tombstone
try and directly contact the correct debuggerd (32 bit vs 64 bit)
by reading the elf information for the executable.
Unfortunately, system_server makes a call to dump_backtrace_to_file
and it doesn't have permissions to read the executable data, so it
defaults to always contacting the 64 bit debuggerd.
This CL changes the code so that all dump requests go to the 64 bit
debuggerd, which reads the elf information and redirects requests for
32 bit processes to the 32 bit debuggerd.
Testing:
- Forced the watchdog code in system_server to dump stacks and
verified that all native stacks are dumped correctly.
- Verified that dumpstate and bugreport still properly dump the native
processes on a 64 bit and 32 bit system.
- Intentionally forced the 64 bit to 32 bit redirect to write only a
byte at a time and verified there are no errors, and no dropped data.
- Used debuggerd and debuggerd64 to dump 32 bit and 64 bit processes
seemlessly.
- Used debuggerd on a 32 bit system to dump native stacks.

1. Accept that parseNetlinkMessage can only parse one netlink
message, because its way of returning output is to modify its
member variables (mAction, mParams, etc.). Currently, it
loops through all the messages it finds, updating its member
variables as it goes along, and always returns true at the end
of the buffer. This has the following problems:
1. Since the function always returns true even when no
messages were parsed, the caller has no way to know if
parsing succeeded, and we get lots of "No subsystem found
in netlink event" logs if the buffer did not contain any
valid messages we were interested in.
2. If there are multiple messages in the buffer, all but the
last message will be silently ignored.
3. If there are multiple messages and previous messages have
more parameters than the last one, the resulting event will
have a mixture of parameters from multiple messages.
Instead of doing all this, change the contract to "parse the
first valid message of interest in the buffer and return true,
or return false if there were no such messages", and update
the code and the comments accordingly.
2. Modify the caller (NetlinkListener) so it doesn't log an
error when parseBinaryNetlinkMessage returns false, because
this can now simply mean that we weren't interested in that
particular message. parseBinaryNetlinkMessage already logs
more informative errors.
3. Provide utility functions to check received message lengths and
to convert message types to message names.
4. Simplify logging duplicate attributes.
5. Use the appropriate IFLA_xxx macros instead of rolling our own
code to parse link state messages.
6. Move all the parsing code out to per-message-type parsing
functions to order to simplify parseBinaryNetlinkMessage.

Currently, /system/xbin/su is world executable. Prior to SELinux
enforcement, anyone (including third party apps) could run su.
The su code itself checks to see if the calling UID is root or shell.
Rather than relying on enforcement within the su binary, modify the
binary so it has group=shell, and remove world-execute permission.
This helps avoid some annoying SELinux denial messages as third party
apps call su on userdebug/eng builds.

This library is dynamically loaded and used by bionic, to replace selected
standard socket syscalls with versions that talk to netd.
Implement connect() by requesting that the socket be marked with the netId of
the default network and then calling through to the actual syscall.
There are two escape hatches:
+ If the fwmark server is unavailable, it isn't an error; we proceed with the
syscall. This might help at boot time (when the server isn't ready yet) and if
we get rid of the fwmarkd socket entirely in future platform versions.
+ If the ANDROID_NO_USE_FWMARK_CLIENT environment variable is set, we don't
attempt to use the fwmark server (even if it's available). This allows apps to
sidestep unforseen issues in production at runtime.

This patch replaces the 'next' parameter with 'n' allowing use of a

This new version doesn't require any specialized thread
implementation, it uses the Current implementation to do its job.
In addition, it runs much faster when multiple threads are trying
to unwind at the same time since the global signal lock is held for
only a small amount of time. Even running through the threads one at
a time should be faster since it no longer requires two passes through
the unwound stacks.
The new code now allows multiple simultaneous unwinds of the
same thread.
Finally, add the ability to unwind from a ucontext_t passed in. This
functionality doesn't work for remote unwinds yet.

field in the GGLSurface structure (where GGLsizei is define as being
ssize_t in the system/core/include/pixelflinger/pixelflinger.h header
file) is uint32_t. That is appropriate to the 32-bit system but is

Extract zip file processing logic from libdvm into a
standalone library.
This library is a stricter than the libdvm library in
several ways:
- Duplicate zip entry names are now disallowed. Files with
such entries will fail to parse.
- We now verify CD file size information with the individual
file header information. (This was pointed out as a deficiency
of this implementation in past discussions.)
- We also add support for crc checking, which means we might
need to parse the optional data descriptor footer (if one
exists).
We also provide an API for iterating over the entries of
a zip file. This library is optimized for two use cases :
- Lookup for a single entry in the file, with the intention
of processing or extracting the data associated with that
entry
- Iterating over all entries in a file *and* processing
/ extracting their data.

Changes the FUSE daemon to synthesize an Android-specific set of
filesystem permissions, even when the underlying media storage is
permissionless. This is designed to support several features:
First, apps can access their own files in /Android/data/com.example/
without requiring any external storage permissions. This is enabled
by allowing o+x on parent directories, and assigning the UID owner
based on the directory name (package name). The mapping from package
to appId is parsed from packages.list, which is updated when apps are
added/removed. Changes are observed through inotify. It creates
missing package name directories when requested and valid.
Second, support for separate permissions for photos and audio/video
content on the device through new GIDs which are assigned based on
top-level directory names.
Finally, support for multi-user separation on the same physical media
through new /Android/user/ directory, which will be bind-mounted
into place. It recursively applies the above rules to each secondary
user.
rwxrwx--x root:sdcard_rw /
rwxrwx--- root:sdcard_pics /Pictures
rwxrwx--- root:sdcard_av /Music
rwxrwx--x root:sdcard_rw /Android

background:
we have some code to fix-up the IDs of references when
using RefBase's DEBUG_REFS when those refs are managed by
arrays wp<> or sp<> (this is because wp<> / sp<> don't have
a trivial ctor when DEBUG_REFS is enabled, and Vector
treats them as trivial for obvious performance reasons)
this is complicated by the fact that we don't want to have
to recompile everything when enabling DEBUG_REFs (i.e.: the
Vector code cannot know wheter it's enabled or not for its
template stuff).
problem:
there was a bug in the fix-up code for wp<> which was trying
to access the weakref_impl from the RefBase* however, this was
moronic since RefBase could have been destroyed if there wasn't
any more strong refs -- and this happned. Instead we need to get
the weakref_impl directly from the wp<>

Bug: 5064702
Introduced the concept of an InputListener to further decouple
the InputReader from the InputDispatcher. The InputListener
exposes just the minimum interface that the InputReader needs
to communicate with the outside world. The InputReader
passes arguments to the InputListener by reference, which makes
it easy to queue them up.
Consolidated all of the InputReader locks into one simple global
Mutex. The reason this wasn't done before was due to potential
re-entrance in outbound calls to the InputDispatcher. To fix this,
the InputReader now queues up all of the events it wants to send
using a QueuedInputListener, then flushes them outside of the
critical section after all of the event processing is finished.
Removing all of the InputMapper locks greatly simplifies the
implementation.
Added tests for new stylus features such as buttons, tool types,
and hovering.
Added some helpers to BitSet32 to handle common code patterns
like finding the first marked bit and clearing it.
Fixed a bug in VelocityTracker where the wrong pointer trace
could get cleared when handling ACTION_POINTER_DOWN. Oops.
Changed PointerCoords so it no longer stores useless zero
axis values. Removed editAxisValue because it is not very

cannot be edited in place.

This is the basic infrastructure for pulling a full(*) backup of the
device's data over an adb(**) connection to the local device. The
basic process consists of these interacting pieces:
1. The framework's BackupManagerService, which coordinates the
collection of app data and routing to the destination.
2. A new framework-provided BackupAgent implementation called
FullBackupAgent, which is instantiated in the target applications'
processes in turn, and knows how to emit a datastream that contains
all of the app's saved data files.
3. A new shell-level program called "bu" that is used to bridge from
adb to the framework's Backup Manager.
4. adb itself, which now knows how to use 'bu' to kick off a backup
operation and pull the resulting data stream to the desktop host.
5. A system-provided application that verifies with the user that
an attempted backup/restore operation is in fact expected and to
be allowed.
The full agent implementation is not used during normal operation of
the delta-based app-customized remote backup process. Instead it's
used during user-confirmed *full* backup of applications and all their
data to a local destination, e.g. via the adb connection.
The output format is 'tar'. This makes it very easy for the end
user to examine the resulting dataset, e.g. for purpose of extracting
files for debug purposes; as well as making it easy to contemplate
adding things like a direct gzip stage to the data pipeline during
backup/restore. It also makes it convenient to construct and maintain
synthetic backup datasets for testing purposes.
Within the tar format, certain artificial conventions are used.
All files are stored within top-level directories according to
their semantic origin:
apps/pkgname/a/ : Application .apk file itself
apps/pkgname/obb/: The application's associated .obb containers
apps/pkgname/f/ : The subtree rooted at the getFilesDir() location
apps/pkgname/db/ : The subtree rooted at the getDatabasePath() parent
apps/pkgname/sp/ : The subtree rooted at the getSharedPrefsFile() parent
apps/pkgname/r/ : Files stored relative to the root of the app's file tree
apps/pkgname/c/ : Reserved for the app's getCacheDir() tree; not stored.
For each package, the first entry in the tar stream is a file called
"_manifest", nominally rooted at apps/pkgname. This file contains some
metadata about the package whose data is stored in the archive.
The contents of shared storage can optionally be included in the tar
stream. It is placed in the synthetic location:
shared/...
uid/gid are ignored; app uids are assigned at install time, and the
app's data is handled from within its own execution environment, so
will automatically have the app's correct uid.
Forward-locked .apk files are never backed up. System-partition
.apk files are not backed up unless they have been overridden by a
post-factory upgrade, in which case the current .apk *is* backed up --
i.e. the .apk that matches the on-disk data. The manifest preceding
each application's portion of the tar stream provides version numbers
and signature blocks for version checking, as well as an indication
of whether the restore logic should expect to install the .apk before
extracting the data.
System packages can designate their own full backup agents. This is
to manage things like the settings provider which (a) cannot be shut
down on the fly in order to do a clean snapshot of their file trees,
and (b) manage data that is not only irrelevant but actively hostile
to non-identical devices -- CDMA telephony settings would seriously
mess up a GSM device if emplaced there blind, for example.
When a full backup or restore is initiated from adb, the system will
present a confirmation UI that the user must explicitly respond to
within a short [~ 30 seconds] timeout. This is to avoid the
possibility of malicious desktop-side software secretly grabbing a copy
of all the user's data for nefarious purposes.
(*) The backup is not strictly a full mirror. In particular, the
settings database is not cloned; it is handled the same way that
it is in cloud backup/restore. This is because some settings
are actively destructive if cloned onto a different (or
especially a different-model) device: telephony settings and
AndroidID are good examples of this.
(**) On the framework side it doesn't care that it's adb; it just
sends the tar stream to a file descriptor. This can easily be
retargeted around whatever transport we might decide to use
in the future.
KNOWN ISSUES:
* the security UI is desperately ugly; no proper designs have yet
been done for it
* restore is not yet implemented
* shared storage backup is not yet implemented
* symlinks aren't yet handled, though some infrastructure for
dealing with them has been put in place.

You can now specify resource configuration variants "wNNNdp"
and "hNNNdp". These are the minimum screen width/height in "dp"
units. This allows you to do things like have your app adjust
its layout based only on the about of horizontal space available.
This introduces a new configuration change flag for screen size.
Note that this configuration change happens each time the orientation
changes. Applications often say they handle the orientation change
to avoid being restarted at a screen rotation, and this will now
cause them to be restarted. To address this, we assume the app can
handle this new config change if its target SDK version is < ICS.

Runtime resource overlay allows unmodified applications to appear
as if they had been compiled with additional resources defined. See
libs/utils/README for more information.
This commit is the first iteration of runtime resource overlay. It
provides the actual overlay modifications and loading of trusted overlay
packages (ie residing in /vendor) targeting framework-res.apk.
This commit loads exactly one overlay package. The overlay,
if present, must target framework-res.apk and be located at
/vendor/overlay/framework/framework-res.apk.

(like when playing a video or using camera) and there was

Replaced VelocityTracker with a faster and more accurate
native implementation. This avoids the duplicate maintenance
overhead of having two implementations.
The new algorithm requires that the sample duration be at least
10ms in order to contribute to the velocity calculation. This
ensures that the velocity is not severely overestimated when
samples arrive in bursts.
The new algorithm computes the exponentially weighted moving
average using weights based on the relative duration of successive
sample periods.
The new algorithm is also more careful about how it handles
individual pointers going down or up and their effects on the
collected movement traces. The intent is to preserve the last
known velocity of pointers as they go up while also ensuring
that other motion samples do not count twice in that case.

1. Single finger tap performs a click.
2. Single finger movement moves the pointer (hovers).
3. Button press plus movement performs click or drag.
While dragging, the pointer follows the finger that is moving
fastest. This is important if there are additional fingers
down on the touch pad for the purpose of applying force
to an integrated button underneath.
4. Two fingers near each other moving in the same direction
are coalesced as a swipe gesture under the pointer.
5. Two or more fingers moving in arbitrary directions are
transformed into touches in the vicinity of the pointer.
This makes scale/zoom and rotate gestures possible.
Added a native VelocityTracker implementation to enable intelligent
switching of the active pointer during drags.

Bug #3461349
This change also fixes two bugs that prevented partial invalidates
from working with other views. Both bugs were in our EGL implementation:
they were preventing the caller from comparing the current context/surface
with another context/surface. This was causing HardwareRenderer to always
redraw the entire screen.

Fades out the mouse pointer:
- after 15 seconds of inactivity normally
- after 3 seconds of inactivity in lights out mode
- after a non-modifier key down
- after a touch down
Extended the native Looper to support enqueuing time delayed
messages. This is used by the PointerController to control
pointer fade timing.

some of the conversion operators were not using the proper
pointer type when calling incStrong/decStrong, usually it
has no bad consequences, but for some implementation
of the ref-counted object it could lead to recording the wrong
owner id.

First slipt sp<> out of RefBase into StrongPointer.h so it can be reused
more easily and to make it clear that it doesn't require RefBase.
Note: the rest of the change only affects the system when DEBUG_REFS is enabled.
The main problem we fix here is that the owner id associated with each
reference could get out of date when a sp<> or wp<> was moved, for
instance when they're used in a Vector< >.
We fix this issue by calling into RefBase::moveReferences from
a template specialization for sp<TYPE> and wp<TYPE> of the
type helpers. RefBase::moveReferences() has then a chance to
update the owner ids.
There is a little bit of trickery to implement this generically in
RefBase, where we need to use a templatized functor that can turn
a sp<TYPE>* casted to a void* into a RefBase*.
Introduced a new debug option DEBUG_REFS_FATAL_SANITY_CHECKS
currently set to 0 by default as there seem to be an issue
with sp<ANativeWindow> which trips the sanity checks.

weak pointer comparison operators were implemented wrong,
they were using the internal "unsafe" pointer. We could end up
with two "equal" weak pointer pointing to different objects.
this caused KeyedVector keyed by weak pointer to work incorrectly, in
turn causing a window that just got added to a list to be immediately
removed.

Previously, display lists were used only if hardware acceleration
was enabled for an application (hardwareAccelerated=true) *and* if
setDrawingCacheEnabled(true) was called. This change makes the framework
use display lists for all views in an application if hardware acceleration
is enabled.
In addition, display list renderering has been optimized so that
any view's recreation of its own display list (which is necessary whenever
the visuals of that view change) will not cause any other display list
in its parent hierarchy to change. Instead, when there are any visual
changes in the hierarchy, only those views which need to have new
display list content will recreate their display lists.
This optimization works by caching display list references in each
parent display list (so the container of some child will refer to its
child's display list by a reference to the child's display list). Then when
a view needs to recreate its display list, it will do so inside the same
display list object. This will cause the content to get refreshed, but not
the reference to that content. Then when the view hierarchy is redrawn,
it will automatically pick up the new content from the old reference.
This optimization will not necessarily improve performance when applications
need to update the entire view hierarchy or redraw the entire screen, but it does
show significant improvements when redrawing only a portion of the screen,
especially when the regions that are not refreshed are complex and time-
consuming to redraw.

Use Vendor ID, Product ID and optionally the Version to
locate keymaps and configuration files for external devices.
Moved virtual key definition parsing to native code so that
EventHub can identify touch screens with virtual keys and load
the appropriate key layout file.
Cleaned up a lot of old code in EventHub.
Fixed a regression in ViewRoot's fallback event handling.
Fixed a minor bug in FileMap that caused it to try to munmap
or close invalid handled when released if the attempt to map
the file failed.
Added a couple of new String8 conveniences for formatting strings.
Modified Tokenizer to fall back to open+read when mmap fails since
we can't mmap sysfs files as needed to open the virtual key
definition files in /sys/board_properties/.
