Subject: [PATCH 0/9] riscv: improve self-protection
Date: Tue, 30 Mar 2021 02:21:44 +0800 [thread overview]
Message-ID: <20210330022144.150edc6e@xhacker> (raw)
From: Jisheng Zhang <jszhang@kernel.org>
patch1 is a trivial improvement patch to move some functions to .init
section
Then following patches improve self-protection by:
Marking some variables __ro_after_init
Constifing some variables
Enabling ARCH_HAS_STRICT_MODULE_RWX
Jisheng Zhang (9):
riscv: add __init section marker to some functions
riscv: Mark some global variables __ro_after_init
riscv: Constify sys_call_table
riscv: Constify sbi_ipi_ops
riscv: kprobes: Implement alloc_insn_page()
riscv: bpf: Move bpf_jit_alloc_exec() and bpf_jit_free_exec() to core
riscv: bpf: Avoid breaking W^X
riscv: module: Create module allocations without exec permissions
riscv: Set ARCH_HAS_STRICT_MODULE_RWX if MMU
