Nativeloader: Restrict anonymous namespace creation

2019-04-29T17:42:38+00:00

Create the anonymous namespace only from a non-empty library path.

This is a better heuristic than the current "first-come" one. It
allows creating classloaders that are not directly related to an
app's "main" classloader, that is, do not have any library path.
This is the case, for example, for shared libraries, including
preloaded ones.

Longer-term, the anonymous namespace creation should be made
explicit, so that the framework can have full control.

Do not fail when there is no vndk namespace

2019-03-25T04:48:43+00:00

Some of the legacy devices may not have vndk namespace. To make this
work, libnativeloader should not fail when it fails to search for vndk
namespace.

Add dependency on libdl_android

platform private symbols have been moved to libdl_android.so
since they are not intended to be accessible from apps.

Add product apk support from libnativeloader

2019-03-07T03:01:23+00:00

Currently libnativeloader appends vendor lib path if apk is from vendor
partition. Similar to this, as part of mainline core, we should add
product lib path if apk if from product partition.

Test: m -j && tested from crosshatch with product apps (such as Wallpaper)

Avoid runtime namespace becoming parent for classloader-namespace.

2019-02-23T03:46:27+00:00

Passing nullptr as parent namespace to android_create_namespace makes it use
the namespace of the caller as parent, which typically is the runtime
namespace. That in turn causes classloader-namespace to inherit any
libraries in the shared group of the runtime namespace, i.e. any libraries
that have been loaded in it with RTLD_GLOBAL or DF_1_GLOBAL up to that
point.

Let's instead pass the platform namespace from the linker config as fallback
when a parent namespace cannot be found. That is also what happened before
libnativeloader moved into the runtime namespace.

Remove dependency on libcutils

2019-02-22T08:55:48+00:00

libnativeloader is in the Runtime Module, libcutils is not.

Dependency was on property_get so moving to libbase equivalent.

shim libraries for libnativeloader and libnativebridge

2019-02-12T10:35:45+00:00

libnativeloader_lazy and libnativebridge_lazy are shim libraries for
libnativeloader and libnativebridge, respectively.

The shim libraries provides the same APIs as their counterparts, but
when the APIs are called, the APIs from the real libraries are
loaded/linked/and executed using dlopen/dlsym.
