2016-11-04Allow different namespace types for different classloadersDimitry Ivanov
An app should be able to make cross-arch calls to different apps via other app's Context.getClassLoader() Bug: 32542970 Test: Boot fugu. Check that there are no linker-namespace related errors in the log. Change-Id: I1593f4688bcde0121a5e24a707441a4935fa7dc4
2016-11-01Return nullptr from FindNamespaceByClassLoader for NB-enabled apps.Dimitry Ivanov
This function is always called by the frameworks in order to initialize vulkan layer path. For NB apps returning nullptr disables vulkan layer library lookup as expected. Bug: http://b/32542970 Test: mm Change-Id: I426b2b9f5ea7227b00f063ed6040f37bb2b4f21f
2016-10-25Upgrade native bridge to version 3 to support namespaceZhenhua WANG
Native bridge implements namespace related interfaces in version 3. The namespace semantic here is same as Android dynamic linker's. Native loader wraps library loading functions of dynamic linker and native bridge. Thus, Android runtime is able to load native library of different ISA on one device by calling native loader directly.

2016-06-22Add support to indicate bitness of public library.Christopher Ferris
For public vendor libraries, a vendor might have only a 32 bit or only a 64 bit version of the library. Add a way to indicate this in the public.libraries.txt files. The new format is: library.so 32 This indicates that this is a 32 bit only public library. library.so 64 This indicates that this is a 64 bit only public library. Bug: 29370721 Bug: 29512261 (cherry picked from commit 6664a805cae6983c7a19caf8abbe88ad2d918bcb) Change-Id: Id52c8b61d5c802ce62edda7e25f2755f6f93d6b7

2016-05-24Remove target_sdk_version parameterDimitry Ivanov
Since linker-namespaces are enabled for all target_sdk_versions and there is no longer need in workarounds in libnativeloader - remove unused target_sdk_version parameter for internal calls. This also brings libnativeloader closer to aosp/master Bug: http://b/26040253 Change-Id: I7d6f6ac31be0dca5f3c3f6ea20e6cc87ce3a3c7f
2016-05-17Merge "Set parent namespace for linker-namespaces" am: ac50d0cc57Dimitry Ivanov
am: 3457aba394 * commit '3457aba39480e85d582dd6890c4c72e418958782': Set parent namespace for linker-namespaces Change-Id: I20ea9239e95377894f477c33cf65bc7da7ad1e5a
2016-05-17Set parent namespace for linker-namespacesDimitry Ivanov
This change allows applications to share RTLD_GLOBAL native libraries between namespaces associated with different classloaders. The rule is - if a library is GLOBAL within namespace associated with parent classloader, it is shared with namespace associated with this classloader Note that the sharing happens on create_namespace event, which is tied to createClassloader in case of application classloaders created by the framework, for custom application classloaders it is tied to first loadLibrary() event.

Now that we have the fixed list of whitelisted libraries there is no longer need to check if java_permitted_path is nullptr.

2016-03-16libnativeloader: Make webviewchromium so file optionalPrashant Malani
Not all android devices ship with Webview. The requirement of libwebviewchromium_plat_support.so to be loaded while initializing the android namespace is therefore liable to cause a crash on devices that don't support or use Webview. Therefore, this patch makes this requirement conditional, but enabled by default.
