Ok. try this patch. This patch is on top of the 5 patches that I had sent last week i.e "[PATCH 0/5] powerpc/pkeys: fixes to pkeys" The following is a draft patch though to check if it meets your expectations. commit fe53b5fe2dcb3139ea27ade3ae7cbbe43c4af3be Author: Ram Pai<linuxram@xxxxxxxxxx> Date: Mon Jun 11 14:57:34 2018 -0500 powerpc/pkeys: Deny read/write/execute by default
With this patch, my existing misc/tst-pkey test in glibc passes. The in-tree version still has some incorrect assumptions on implementation behavior, but those are test bugs. The kernel behavior with your patch look good to me. Thanks.
