Subject: [PATCH v10 00/10] powerpc: Further Strict RWX support
Date: Tue, 30 Mar 2021 15:51:22 +1100 [thread overview]
Message-ID: <20210330045132.722243-1-jniethe5@gmail.com> (raw)
Another revision to this series adding more Strict RWX support on powerpc, in
particular Strict Module RWX. This revision adds consideration for bpf.
The changes in v10 for each patch:
Christophe Leroy (2):
powerpc/mm: implement set_memory_attr()
powerpc/32: use set_memory_attr()
Jordan Niethe (3):
powerpc/lib/code-patching: Set up Strict RWX patching earlier
powerpc: Always define MODULES_{VADDR,END}
v10: - New to series
powerpc/bpf: Write protect JIT code
v10: - New to series
Russell Currey (5):
powerpc/mm: Implement set_memory() routines
v10: - WARN if trying to change the hash linear map
powerpc/kprobes: Mark newly allocated probes as ROX
v10: - Use __vmalloc_node_range()
powerpc/mm/ptdump: debugfs handler for W+X checks at runtime
v10: check_wx_pages now affects kernel_page_tables rather
then triggers its own action.
powerpc: Set ARCH_HAS_STRICT_MODULE_RWX
v10: - Predicate on !PPC_BOOK3S_604
- Make module_alloc() use PAGE_KERNEL protection
powerpc/configs: Enable STRICT_MODULE_RWX in skiroot_defconfig
