RFR: Fix runtime/7107135/Test7107135.jtr - execstack problems
by Edward Nevill 28 Feb '14

28 Feb '14

Hi, The following patch fixes a problem in the jtreg test suite. The test is "runtime/7107135/Test7107135.jtr" which currently causes a SEGV on aarch64. Basically what the test does is loads a shared library with executable stack set. The test then checks that the VM correctly detects this and re-enables the stack guard. Now, on x86, if it is not specified in a shared library, it is assumed that the stack is executable. This is for historical reasons. On aarch64 it is assumed that the stack is not executable. This lead to a path of execution where on aarch64 the VM thought that every shared library it loaded had executable stack! Now because the kernel only enables executable stack on the first load of a dll with executable stack, the VM only restores the guard on the first load of a dll with executable stack. This meant that when a genuine dll with executable stack was loaded, the VM did not re-enable the stack guard because it thinks it is not necessary because it has done so already. I have tested this on both aarch64 and x86 and it now passes on both. OK to push?

RFR: Fix Zero build failure
by Edward Nevill 28 Feb '14

28 Feb '14

Hi, The zero build currently generates Error: dl failure on line 873 Error: failed /home/ed/images/j2sdk-zero-release/jre/lib/aarch64/server/libjvm.so, because /home/ed/images/j2sdk-zero-release/jre/lib/aarch64/server/libjvm.so: undefined symbol: _ZN15MetaspaceShared18relocate_vtbl_listEPPc The following patch fixes this. There were 2 ways to fix this 1) add a (null) definition of relocate_vtbl_list to Zero 2) Conditionalize out the reference The existing reference was already conditionalised on AARCH64. Changing this to BUILTIN_SIM fixes the problem and I think better reflects the intent. Ok to push?
