use with mprotect(2), but without enabling them immediately. Extend the mremap(2) interface to allow duplicating mappings, i.e. create a second range of virtual addresses references the same physical pages. Duplicated mappings can have different effective protections. Adjust PAX mprotect logic to disallow effective protections of W&X, but allow one mapping W and another X protections. This obsoletes using temporary files for purposes like JIT. Adjust PAX logic for mmap(2) and mprotect(2) to fail if W&X is requested and not silently drop the X protection. Improve test cases to ensure correct operation of the changed interfaces. |
