This commit updates interface of libdl.c. 1. android_init_namespaces is replaces with android_init_anonymous_namespace 2. added 2 arguments to android_create_namespace to specify linked namespace and the list of shared libraries sonames. 3. symbol lookup does not get past boundary libraries (added check and test for it). Bug: http://b/26833548 Bug: http://b/21879602 Test: bionic-unit-tests --gtest_filter=dl*:Dl* Change-Id: I32921da487a02e5bd0d2fc528904d1228394bfb9

# Test cases
|
|
# 1. Check that private libraries loaded in different namespaces are
|
|
# different. Check that dlsym does not confuse them.
|
|
# 2. Check that public libraries loaded in different namespaces are shared
|
|
# between them.
|
|
# 3. Check that namespace sticks on dlopen
|
|
# 4. Check that having access to shared library (libnstest_public.so)
|
|
# does not expose symbols from dependent library (libnstest_public_internal.so)
