Subject: [PATCH v11 0/9] powerpc: Further Strict RWX support
Date: Thu, 29 Apr 2021 13:15:53 +1000 [thread overview]
Message-ID: <20210429031602.2606654-1-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.
For reference the previous revision is available here:
https://lore.kernel.org/linuxppc-dev/20210330045132.722243-1-jniethe5@gmail.com/
The changes in v11 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: Always define MODULES_{VADDR,END}
v11: - Consider more places MODULES_VADDR was being used
powerpc/bpf: Remove bpf_jit_free()
v11: - New to series
powerpc/bpf: Write protect JIT code
v11: - Remove CONFIG_STRICT_MODULE_RWX conditional
Russell Currey (3):
powerpc/mm: Implement set_memory() routines
v11: - Update copywrite dates
- Allow set memory functions to be used without Strict RW
- Hash: Disallow certain regions and add comment explaining why
- Have change_page_attr() take function pointers to manipulate ptes
- Clarify change_page_attr()'s comment
- Radix: Add ptesync after set_pte_at()
powerpc/kprobes: Mark newly allocated probes as ROX
v11: Neaten up
powerpc: Set ARCH_HAS_STRICT_MODULE_RWX
v11: Neaten up
Some patches were dropped from this revision:
powerpc/mm/ptdump: debugfs handler for W+X checks at runtime
- Will use Christophe's generic ptdump series
powerpc/configs: Enable STRICT_MODULE_RWX in skiroot_defconfig
- Will enable STRICT_MODULE_RWX by default later
