Instead of linking the unwinder statically into every binary, link it
dynamically, by exporting the symbols from libc.so. This has a number
of advantages:
- Reduces image size (system.img size decreases by 1.7MB on walleye-userdebug,
and 1.2MB on crosshatch-userdebug).
- Allows us to easily change/upgrade the unwinder throughout the system,
including vendor prebuilts.
- Allows code outside of libc++ to define custom personality routines.
Previously, personality routines would call the unwinder routines in the
local binary, which would cause problems with unwinders with global state
(such as the libgcc unwinder) if the copy of the unwinder used for unwinding
(normally libc++'s copy) were different from the copy linked against the
personality routine.

This change fixes a bug that test modules (cc_test or its sub types) are
unconditionally considered as non-installable if they are configured to
not available for platform. The rationale behind the decision was that
an APEX variant of a module doesn't need to be installed to the device
because the variant will anyway be included in the APEX. However, it's
wrong for test modules. They are not included in the APEX, but should be
installed to /data/nativetest*.
One might think that we need to make the tests available for the
platform (i.e. apex_available: ["//apex_available:platform"]). This
however doesn't work if the libraries that the tests should link against
are configured to be not available for the platform, which currently is
the case for the ART tests.

We need to have a way to see the list of modules that directly or
indirectly contribute to an APEX. People find it difficult to determine
whether a module is included in which APEXes because APEX tracks
indirect dependencies as well as direct dependencies. Therefore, just
looking at Android.bp for the APEX itself doesn't give the answer.
This change adds a new make target <apex_name>-deps-info, which
generates out/soong/<apex_name>-deps-info.txt file that shows the
internal and external dependencies of the said APEX.
Here, internal means the dependencies are actually part of the
APEX, while external means the dependencies are still external to the
APEX.

Previously, android_app targets for which a.shouldEmbedJnis(ctx) = true
(e.g. CtsSelinuxTargetSdk25TestCases) would need to specify all of their
recursive library dependencies, including for example libc++ when depending
on the platform libc++. This means unnecessary churn when we add a new
dependency to libc++ (e.g. libunwind [1]). To avoid the churn and allow
jni_libs clauses to be simplified, make the build system search for the
recursive dependencies and automatically include them.
This change allows us to remove code that was previously adding NDK libc++
as a special case, as it is now covered by the generic code.
Also fix some improper quoting that was exposed as a result of this change

The clang-r370808 upgrade contains a change to LLD allow PT_LOAD
segments to reside at non-multiples of the page size in the resulting
object file. https://reviews.llvm.org/rL369344
While this helps reduce the alignment waste and resulting image size, it
has interesting implications for execute only memory (XOM): The runtime
loader will now load code or data from other segments into pages with
different protections than intended.
This would partially defeat execute only (XOM) text sections as the
segment could now overlap with previous and following sections. This
might allow for code or data from the preceding and following sections
(like .eh_frame, and .data.rel.ro) to be executable, and either ends of
.text to be readable.
When the runtime loader (linker[64]) `mmap`s segments from *.so files,
the file offset parameter (see `man 2 mmap`) MUST be a multiple of the
page size. Since the updated LLD can now pack segments in a file (which
helps minimize resulting object file size) (previously, the segment
offsets were page aligned), this has interesting implications.
To appreciate the current bug, consider the following output from
`readelf` before this patch is applied, but after the toolchain upgrade:
```

The above output tells us:
1. .text will wind up in the third (02) segment.
2. The third segment will be (LOAD)'ed as (E)xecutable.
3. Because the file (Offset) of the first segment (0x41b40) is NOT a
multiple of the page size, it cannot be passed as the `offset` to
`mmap`. As such it will be rounded down to the first multiple of the
page size, 0x41000.
4. The preceding section (.eh_frame) will be loaded in the preceding
segment (01). It occupies file (Off)set range [(0x2e7c0):0x41b34].
0x41b34 is not explicit in the output, instead you must use the
formula:
Off + Size == End
ie.
0x2e7c0 + 0x13374 == 0x41b34
(This happens to match (FileSiz) of the second segment, which makes
sense as .eh_frame is the final section in the second segment.)
5. mmap'ing file offset 0x41000 when loading the second segment will
include 0x4c0 bytes (0x42000 - 0x41b40) from .text, now mapped as
readable (oops). Suddenly code from .text is now readable (and thus
scannable for gadgets for ROP chains).
6. mmap'ing file offset 0x41000 when loading the third segment will
include 0xb34 bytes (0x41b34 - 0x41000) from .eh_frame, now mapped as
executable (oops). Suddenly data from .eh_frame is now executable
(and thus a potential gadget for ROP chains).
7. mmap'ing file offset 0xe2000 when loading the third segment will
include 0x8CO bytes (0xe3000 - 0xe2740) from .data.rel.ro, now mapped
as executable (oops). Suddenly data from .data.rel.ro is now
executable (and thus a potential gadget for ROP chains).
8. mmap'ing file offset 0xe2000 when loading the fourth segment will
include 0x730 bytes (0xe0800 + 0x1f30 - 0xe2000) from .plt, now
mapped as readable (oops). Suddenly data from .plt is now readable
(and thus scannable for gadgets for ROP chains).
All these oops' could be avoided if the linker placed .text+.plt at page
size aligned file offsets, which is what `-Wl,-z,separate-code` code
does. After this patch, we have:
```
$ readelf -lSW $OUT/symbols/apex/com.android.runtime/lib64/bionic/libc.so
...

```
In the future, we could go back to tightly packing segments in the
binary if the runtime loader was improved to detect the previously
stated problem, and `memset` over the problematic ranges of the freshly
`mmap`ed pages (implying additional startup cost for reduced binary
size). This might save ~6 KB from each native binary, which adds up to
~17 MB for an AOSP image.
Also, prefer
-Wl,--execute-only
rather than
-Wl,-execute-only

Previously, adding a new SdkMemberType would require adding a new
sdkMemberListProperty instance to the sdkMemberListProperties as well
as adding a new property into the sdkProperties struct. They are
potential sources of conflict and couple the sdk code with all the
packages that add members to it. This change switched to a
registration model that allows each package to register its sdk
member types decoupling them from the sdk code.
Adds an SdkPropertyName() method to SdkMemberType that specifies the
name of the property to use in the sdk/sdk_snapshot. Also provides
an SdkMemberTypeBase struct to be used by providers of SdkMemberType
implementations.
SdkMemberType instances are registered using the
RegisterSdkMemberType() func which sorts the registered instances
by their SdkPropertyName() to ensure the behavior is consistent and
not affected by order of registration.
When creating a new sdk module a dynamicSdkMemberTypes instance is
created that contains the following:
* A properties struct is created dynamically that contains a field for
each registered SdkMemberType, corresponding to that type's
SdkPropertyName().
* A list of sdkMemberListProperty instances is also created, one for
each registered SdkMemberType.
The dynamicSdkMemberTypes instance is cached using a key that uniquely
identifies the set of registered types just in case new types are
registered after one has been created, e.g. by tests.

The exported include dirs includes both source and generated
directories (e.g. containing aidl generated headers). The latter are
always arch specific so if they are present they make all the include
directories arch specific.
This change separates the source and generated include dirs so that
the source include dirs (which are probably not arch specific) can be
optimized separately from the arch specific generated include dirs.
The FilterPathList() func was refactored to extract the more general
FilterPathListPredicate() func.
A number of tests needed to be updated to reflect the more optimal
snapshot creation.

Previously, code that attempted to optimize the generated .bp rules
treated the properties structure as a single entity. So, a single arch
specific value would cause all properties to be treated as arch
specific. Also, that code was specific to one structure type.
This generalizes the optimization to work with any properties structure
which will be helpful for other multi-variant module types. It also
treats each property separately.
The hasArchSpecificFlags field has been removed from nativeLibInfo and
a commonProperties field has been added instead into which the common
values will be found. File path creation that conditionally prefixed a
path with archType has been replaced with general code that relies on
archType being "" for common properties and filepath.Join(..) ignoring
empty string components.
The common and arch variant properties are always processed. The first
within the context of the .bp module's property set and the latter
within an arch specific property set. There are always some properties
that are arch specific, e.g. outputFile, so there is no need to worry
about an empty arch property set being created.
The archSpecificNativeLibInfo type was renamed nativeLibInfoProperties
as it may not be arch specific.
The printExportedDirCopyCommandsForNativeLibs variable was renamed to
addExportedDirCopyCommandsForNativeLibs as it no longer does any
printing.

Parameterized the cc.librarySdkMemberType to allow it to support
both static and shared libraries. Created two instances, one for shared
and one for static libraries. A follow up change will add support for
libraries that can be both.
Added *librarySdkMemberType to nativeMemberInfo as information from
there is needed when generating the snapshot.
Made organizeVariants() func a method of *librarySdkMemberType so that
it can initialize the new field. Moved it to be with all the other
methods of that type.
Added host and device tests for the new module type.

Build fuzzer-sanitized libraries with an $ORIGIN DT_RUNPATH. Android's linker
uses DT_RUNPATH, not DT_RPATH. When we deploy cc_fuzz targets and their
libraries to /data/fuzz/<arch>/lib, any transient shared library gets the
DT_RUNPATH from the shared library above it, and not the executable, meaning
that the lookup falls back to the system. Adding the $ORIGIN to the DT_RUNPATH
here means that transient shared libraries can be found colocated with their
parents.
This may have some interesting consequences if:
1. Your fuzz target depends on a shared library which has `sanitize.fuzzer:
false` (as the DT_RUNPATH won't have `$ORIGIN`, and so you may get missing
libraries).
2. A `SANITIZE_TARGET=fuzzer` platform has a shared object in two
different directories (like system vs. ndk) and is depending on the linker
implementation details to resolve this in some manner.
I don't believe either of these instances should reasonably happen in
practise.

Extracts the type specific functionality into the SdkMemberType
interface which has to be implemented by each module type that can
be added as a member of the sdk. It provides functionality to add
the required dependencies for the module type, check to see if a
resolved module is the correct instance and build the snapshot.
The latter was previously part of SdkAware but was moved because
it has to be able to process multiple SdkAware variants so delegating
it to a single instance did not make sense.
The custom code for handling each member type specific property,
e.g. java_libs, has been replaced with common code that processes
a list of sdkMemberListProperty struct which associates the
property (name and getter) with the SdkMemberType and a special
DependencyTag which is passed to the SdkMemberType when it has to add
dependencies.
The DependencyTag contains a reference to the appropriate
sdkMemberListProperty which allows the resolved dependencies to be
grouped by type.
Previously, the dependency collection methods would ignore a module if
it was an unsupported type because they did not have a way of
determining which property it was initially listed in. That meant it
was possible to add say a droidstubs module to the java_libs property
(and because they had the same variants) it would work as if it was
added to the stubs_sources property. Or alternatively, a module of an
unsupported type could be added to any property and it would just be
ignored.
However, the DependencyTag provides information about which property
a resolved module was referenced in and so it can detect when the
resolved module is of the wrong type and report an error. That check
identified a bug in one of the tests where the sdk referenced a
java_import module (which is not allowed in an sdk) instead of a
java_library module (which is allowed). That test was fixed as part
of this.
A list of sdkMemberListProperty structs defines the member properties
supported by the sdk and are processed in order to ensure consistent
behaviour.
The resolved dependencies are grouped by type and each group is then
processed in defined order. Within each type dependencies are grouped
by name and encapsulated behind an SdkMember interface which includes
the name and the list of variants.
The Droidstubs and java.Library types can only support one variant and
will fail if given more.
The processing for the native_shared_libs property has been moved into
the cc/library.go file so the sdk package code should now have no type
specific information in it apart from what is if the list of
sdkMemberListProperty structs.

This also solves b/144418402, where we are very close to hitting the

The APIs that are tagged with # vndk are actually for LLNDK libraries.
Although LLNDK is part of VNDK, calling those APIs 'vndk' has given
users a wrong perception that the APIs don't need to be kept stable
because that's the norm for most of the VNDK libraries that are not
LLNDK.
In order to eliminate the misunderstanding, rename the tag to 'llndk' so
that people introducing new such API will realize what they are signing

Change the ClusterFuzz package built by 'make fuzz' to now package
shared libraries per-fuzz target.
Changes documented in go/proposed-clusterfuzz-package
This has the impact of:
- This package is much easier to post-process in the Haiku export
cronjob.
- Shared libraries are now per-fuzz-target. This means that we will
have some level of duplication (libdl, libc, libc++, libclang_rt.*,
etc.) as these libraries will be in multiple fuzz target's dirs.
This *only* affects the fuzz-$target-$arch.zip file, not the fuzz targets in
$ANDROID_HOST_OUT/fuzz or $ANDROID_PRODUCT_OUT/data/fuzz. These two
install directories still use the global shared libraries in order to
preserve space on devices.
