I don't think that new way is yet supported in the kernel that we shipped, but I may misremember... The latest kernel in RHN (and tomorrow in rawhide) has the latest exec-shield in it. If you build something with gas directly, you can pass the --execstack option to gas; otherwise, use the compiler argument -Wa,--execstack to tell the compiler to tell gas to request an executable stack. Alternatively, if you have assembler sources, you can also add .section .note.GNU-stack,"x"; .previous to the assembler source; that's what the --execstack option does. How that needs to be factored into qemu building I don't know; as you point out, that may be a bit complex... michaelkjohnson "He that composes himself is wiser than he that composes a book."

You'd use the assembler method if you were going to be creating a library archive and didn't know if the object requiring execstack was going to be included or not. The linker switch overrides everything that may have been stored in the object files. Not the linked binary. We create a PT_GNU_STACK header that the kernel is to use. You can't strip that. r~
