OK, got it! Thanks for this clarification. So, I will try to start to port PAX_REFCOUNT arm-specific features to hardened_atomic_on_next, and keep you in touch. Is there a deadline? (4.10 / 5.0 merge window?) Just to be sure, the patch [1] and documentation [2] of PaX are still up-to-date, or there is another references I missed? Thanks Colin [1] https://pax.grsecurity.net/pax-linux-3.6-201210022100.patch [2] https://forums.grsecurity.net/viewtopic.php?f=7&t=4173
