Rationale ========= - Separation of executable code and non-executable data is a good thing. - Additional security in Python is a good idea. - Python should support things like the NX bit to separate code and non-executable data.
Discussion ========== How could Python implement support for the NX bit? (And/or additional modern security measures; as appropriate). What sort of an API would C extensions need? Would this be easier in PyPy or in CPython? - https://en.wikipedia.org/wiki/NX_bit - https://en.wikipedia.org/wiki/Executable_space_protection Here's one way to identify whether an executable supports NX: https://github.com/longld/peda/blob/e0eb0af4bcf3ee/peda.py#L2543
