2019-05-01Reland: Fix libnativeloader to correctly link to the platform namespace.Martin Stjernholm
This relands http://r.android.com/951440: This affected binaries in the Runtime APEX, where the platform namespace is "platform" rather than "default". Also extend ANDROID_ADDITIONAL_PUBLIC_LIBRARIES to create links to both to platform and runtime namespaces, so that it can be used to open up access to internal libraries in the Runtime APEX as well, which is used by ART gtests and run tests. Also update some comments in the ld.config*.txt files to accurately explain why some namespaces need to be visible, and some other minor changes for consistency. There are no semantically significant changes in those files.

2019-04-26Nativeloader: Restrict anonymous namespace creationAndreas Gampe
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.

2019-02-23Avoid runtime namespace becoming parent for classloader-namespace.Martin Stjernholm
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.

2017-12-19Support partners to expose their own system libs to Android appsJiyong Park
Partners (entities other than AOSP) can expose their own system libraries which are in /system/lib[64] to Android apps. This can be done by adding the name of the libs into the files /system/etc/public.libraries-<companyname>.txt. There can be multiple of the txt files on a device, which is for the case that multiple partners contributing to the same system image have their own set of public libraries. The public libraries MUST be named as lib<name>.<companyname>.so. This is to prevent accidental exposure of AOSP-defined system private libs. Note 1: <companyname> doesn't need to be the same as the value of the sysprop ro.product.manufacturer or anything that can be part of a file path. Note 2: This feature is not for exposing SoC-specific libs to Android apps. That is already done by /vendor/etc/public.libraries.txt and is only for libs in /vendor/lib[64].

2017-12-13Load versioned llndk.libraries.txt and vndksp.libraries.txtJustin Yun
When ro.vndk.version has a specific VNDK version in it, use the llndk.libraries.txt and vndksp.libraries.txt files with the version suffix in the file names. If ro.vndk.version is "current" or not set, the version suffix will not be added. This is to use a proper VNDK snapshot version configuration for a vendor patition. Bug: 69531793 Test: In system/etc directory of a Pixel2 device, Change llndk.libraries.txt to llndk.libraries.27.txt Change vndksp.libraries.txt to vndksp.libraries.27.txt Set ro.vndk.version to 27 in vendor/default.prop reboot and check if vendor apks work.

2017-09-07vendor apk is unbundledJiyong Park
For devices where VNDK restrictions are all enforced, vendor apks are recognized as unbundled; since system partition and vendor partition can be updated independently from each other. However, since vendor apks are still bundled in the vendor partition, they are allowed to do more than ordinaly unbundled apks that are downloaded and installed to the data partition. 1) /vendor/lib is allowed. So the path is added to the search_paths and permitted paths of the classloader namespace. 2) LLNDK libs are allowed in addition to the NDK libs. So, LLNDK lib list from llndk.libraries.txt is added to the list from public.libraries.txt. 3) VNDK-SP libs are allowed. To do so, the classloader namespace is linked to the 'vndk' namespace where VNDK-SP libs are searched and loaded from. The list of available VNDK-SP libs is read from vndksp.libraries.txt file. 4) Name of the namespace is changed to 'vendor-classloader-namespace' since the namespace is configured differently from the ordinary 'classloader-namespace'. Bug: 63553457 Test: 2017 pixel devices build and boots to the UI Test: a vendor apk (e.g. TimeService.apk) works. Turn the airplain mode on. Set time. Reboot the device. The time is not reset.
