Peter Collingbourne e5ba28648f build: Link the unwinder dynamically into platform and vendor binaries.
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.

Jiyong Park fe9a43002e A test cc module is installable even if it's not available for platform
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.

Jiyong Park 114ff53f5e m <apex_name>-deps-info prints the internal/external deps of the APEX
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.

Paul Duffin a0843f6a6f Differentiate between cc library and binary
The cc library and cc binary (and other cc module types) are all
instances of cc.Module. So, to differentiate between them and make
sure that only appropriate library instances can be added to
native_shared/static_libs this adds a special sdkMemberTypes field to
Module which if set specifies the SdkMemberTypes the module supports.
If it is not set then the module type cannot be used in the sdk at all.

Corrects an issue with one of the tests where a prebuilt cc
library was added to the sdk instead of a source cc library.

Adds a new test to ensure that cc_library_(shared|static)_host module
types work with the sdk as well and another test to ensure that
cc_library can be used as either.

When PRODUCT_PRODUCT_VNDK_VERSION is set to 'current', product
modules are enforced to use only VNDK libs from the system partition
as BOARD_VNDK_VERSION does to vendor partition.

Modules with 'vendor_available: true' create product variant as well
as core and vendor variants. The product variant as an image variant
is used for the modules in /product or /system/product.

It must not affect the current build behavior without

Paul Duffin 075c417837 Improve cc tests by adding fuzzer mutators
This fixes an issue that arises when deduping cc build component
registration code.

The fuzzer and fuzzer_deps post deps mutators were not previously
added when running cc tests. That meant the tests were not actually
testing the same behavior as at runtime.

Adding the mutators breaks the TestFuzzTarget test as the mutator
changes the variant of the fuzz_smoke_test that is created and so the
test fails to find it.

This fixes the test by correct the variant name.

Peter Collingbourne 6f907ad3dd Also package recursive jni_libs deps of android_apps as well as direct deps.
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
causing more files to be packaged than before.

Nick Desaulniers dcee1e5c54 soong: use -Wl,-z,separate-code w/ -Wl,--execute-only
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:

```

   02     .text .plt
   03     .data.rel.ro .fini_array .init_array .dynamic .got .got.plt
...

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
...
  Type           Offset   VirtAddr           PhysAddr           FileSiz  MemSiz   Flg Align
  PHDR           0x000040 0x0000000000000040 0x0000000000000040 0x000230 0x000230 R   0x8
  LOAD           0x000000 0x0000000000000000 0x0000000000000000 0x041b34 0x041b34 R   0x1000
  LOAD           0x042000 0x0000000000042000 0x0000000000042000 0x0a0be0 0x0a0be0   E 0x1000

```

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

Paul Duffin 255f18e584 Decouple addition of new sdk member types from sdk code
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.

Paul Duffin 57b9e1da75 Improve handling of generated include dirs
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.

Paul Duffin a7cd8c8344 Generalize common property extraction
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.

Mitch Phillips 734b4cb62f Add $ORIGIN to fuzzer-coverage sanitized .so's.
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.

Paul Duffin 9d8d609fcd Pass SdkMember to AddPrebuiltModule instead of the name
This is needed for a follow up change that makes sure that the
prebuilt modules have the same visibility as the source modules.

Inseob Kim d110f878a7 Fix generated headers of snapshot
For VNDK snapshot and SDK snapshot, deps files have been used to capture
generated headers. But exported deps might contain intermediate phony
files instead of actual header files, which are for optimization of
ninja. To correctly capture all headers, exported generated header files
are gathered separately.

Paul Duffin 1387957727 Parameterize the sdk member processing
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.

Tri Vo ad172d88b6 cc_fuzz: add "data" field
"data" field specifies data dependencies that will be installed in
fuzzer's output directory.

"data" behaves similar to "corpus", except "data" preserves directory
structure, e.g.

    data: ["foo/bar.txt"]

is installed into

    $OUT/data/fuzz/<arch>/<target>/data/foo/bar.txt

Test: build a fuzzer with data depenency, check data is installed
correctly

Mitch Phillips 6a9bf214f9 Fix cc_fuzz ignoring soong namespaces.
cc_fuzz ignored soong namespaces, and built all cc_fuzz modules into the
architecture package. This caused naming conflicts where two modules had
the same name but were in different namespaces.

Now, cc_fuzz will only build modules that are in the same namespace as
the product definition - resolving the duplicate definitions error.
