| |
A patch to remove VM_EXEC from VM_DATA_DEFAULT_FLAGS for MIPS has been submitted to me with the primary motivation for this change being some performance improvment. In other words, the patch would remove execute permission from a process brk area. It's however unclear to me how much software wreckage would result from such a change, even if the execute permission for the stack area remains unchanged.
So, what would break?
Thanks,
Ralf
