Possible dlopen() issue: ignoring or misinterpreting RPATH entries with $ORIGIN
by Alex Potapenko 18 Nov '15

18 Nov '15

While porting OpenJDK8 to Optware-ng, I have encountered an issue of compiled java being unable to load libjava.so. With JamVM the output is this: [root@unknown bin]$ java -version > Error initialising natives: couldn't open libjava.so: use -verbose:jni for > more information > Error initialising VM (initialiseNatives) > Error: Could not create the Java Virtual Machine. > Error: A fatal exception has occurred. Program will exit. > [root@unknown bin]$ java -verbose:jni -version > [Failed to open library /opt/lib/jvm/openjdk8/jre/lib/arm/libjava.so: File > not found] > Error initialising natives: couldn't open libjava.so: use -verbose:jni for > more information > Error initialising VM (initialiseNatives) > Error: Could not create the Java Virtual Machine. > Error: A fatal exception has occurred. Program will exit. With Hotspot Zero VM it looked a bit different, but was the same issue: dlopen() failed when trying to load libjava.so. With glibc, it was fine. After googling a bit, I discovered that this may be the case of unsatisfied dependencies, however java was compiled with relative RPATH entries (containing $ORIGIN) that pointed to the needed libs: [root@unknown bin]$ readelf -d java > Dynamic section at offset 0x788 contains 29 entries: > Tag Type Name/Value > 0x00000001 (NEEDED) Shared library: [libm.so.1] > 0x00000001 (NEEDED) Shared library: [libdl.so.1] > 0x00000001 (NEEDED) Shared library: [libiconv.so.2] > 0x00000001 (NEEDED) Shared library: [libpthread.so.1] > 0x00000001 (NEEDED) Shared library: [libz.so.1] > 0x00000001 (NEEDED) Shared library: [libjli.so] > 0x00000001 (NEEDED) Shared library: [libc.so.1] > 0x0000000e (SONAME) Library soname: [lib.so] > 0x0000000f (RPATH) Library rpath: > [/opt/lib:$ORIGIN/../lib/arm/jli:$ORIGIN/../lib/arm] ... I then compiled with additional absolute RPATH entries, which pointed to the relevant libraries: [root@unknown bin]$ readelf -d java > Dynamic section at offset 0x788 contains 29 entries: > Tag Type Name/Value > 0x00000001 (NEEDED) Shared library: [libm.so.1] > 0x00000001 (NEEDED) Shared library: [libdl.so.1] > 0x00000001 (NEEDED) Shared library: [libiconv.so.2] > 0x00000001 (NEEDED) Shared library: [libpthread.so.1] > 0x00000001 (NEEDED) Shared library: [libz.so.1] > 0x00000001 (NEEDED) Shared library: [libjli.so] > 0x00000001 (NEEDED) Shared library: [libc.so.1] > 0x0000000e (SONAME) Library soname: [lib.so] > 0x0000000f (RPATH) Library rpath: > [/opt/lib/jvm/openjdk8/jre/lib/arm/jli:/opt/lib/jvm/openjdk8/jre/lib/arm:/opt/lib:$ORIGIN/../lib/arm/jli:$ORIGIN/../lib/arm] ... And, java took off: > [root@unknown bin]$ java -version > openjdk version "1.8.0_60-Optware-ng" > OpenJDK Runtime Environment (build 1.8.0_60-Optware-ng-b24) > JamVM (build 2.0.0, inline-threaded interpreter with stack-caching) I've experienced this kind of behavior with JamVM and Hotspot Zero VM on ARMv7 and MIPSEL archs with uclibc-ng-1.0.6. It worked OK with glibc, so I'm guessing this is a uclibc-ng issue. Maybe, something wrong with the way dlopen() function deals with RPATH entries that contain $ORIGIN. -- Best regards, Alex Potapenko
