Subject: [PATCH v14 0/9] powerpc: Further Strict RWX support
Date: Mon, 17 May 2021 13:28:01 +1000	[thread overview]
Message-ID: <20210517032810.129949-1-jniethe5@gmail.com> (raw)

Adding more Strict RWX support on powerpc, in particular Strict Module RWX.
Thanks for all of the feedback everyone.
It is now rebased on linux-next + powerpc/64s/radix: Enable huge vmalloc mappings
(https://lore.kernel.org/linuxppc-dev/20210503091755.613393-1-npiggin@gmail.com/)

For reference the previous revision is available here: 
https://lore.kernel.org/linuxppc-dev/20210510011828.4006623-1-jniethe5@gmail.com/

The changes in v14 for each patch:

Christophe Leroy (2):
  powerpc/mm: implement set_memory_attr()
  powerpc/32: use set_memory_attr()

Jordan Niethe (4):
  powerpc/lib/code-patching: Set up Strict RWX patching earlier
  powerpc/modules: Make module_alloc() Strict Module RWX aware
    v14: - Split out from powerpc: Set ARCH_HAS_STRICT_MODULE_RW
    - Add and use strict_module_rwx_enabled() helper
  powerpc/bpf: Remove bpf_jit_free()
  powerpc/bpf: Write protect JIT code

Russell Currey (3):
  powerpc/mm: Implement set_memory() routines
    v14: - only check is_vm_area_hugepages() for virtual memory
  powerpc/kprobes: Mark newly allocated probes as ROX
    v14: - Use strict_module_rwx_enabled()
  powerpc: Set ARCH_HAS_STRICT_MODULE_RWX
    v14: - Make changes to module_alloc() its own commit
