Mark Wielaard <mwielaard@redhat.com> writes: On some systems executable stacks are denied. Since libunwind and the tests don't actually need executable stacks this patch marks all assembly files as not needing it. The original patch comes from frysk: 2007-04-05 Jan Kratochvil <jan.kratochvil@redhat.com> * src/hppa/getcontext.S, src/hppa/setcontext.S, src/hppa/siglongjmp.S, src/ia64/Ginstall_cursor.S, src/ia64/Linstall_cursor.S, src/ia64/dyn_info_list.S, src/ia64/getcontext.S, src/ia64/longjmp.S, src/ia64/setjmp.S, src/ia64/siglongjmp.S, src/ia64/sigsetjmp.S, src/ppc64/longjmp.S, src/ppc64/siglongjmp.S, src/x86/longjmp.S, src/x86/siglongjmp.S, src/x86_64/longjmp.S, src/x86_64/setcontext.S, src/x86_64/siglongjmp.S: Stack should be non-executable, for SELinux. I added a couple more markers for new files in current libunwind. Before this patch you would get the following on selinux enabled systems without allow_exec_stack: error while loading shared libraries: libunwind.so.7: cannot enable executable stack as shared object requires: Permission denied After the patch that error disappears and all test results are similar to the results on systems without executable stack protection. 2007-10-01 16:35:01 +02:00
