Hi Ingo, What would you think about fixing this way? This makes the instruction buffer always RO and poke it via text_poke. Thank you, On Fri, 18 Aug 2017 17:22:54 +0900 Masami Hiramatsu wrote: > Hi, > > This series modifies how to handle RO insn buffer and > cleans up addressof operators. >

[PATCH -tip v3 0/2] kprobes/x86: Another way to make insn buffer RO and cleanup

Hi, This series modifies how to handle RO insn buffer and cleans up addressof operators. The 1st patch changes the RO insn buffer handling: instead of using set_memory_ro/rw to modify the buffer, it prepares new instructions in another buffer and write it with text_poke() as suggested by Ingo Mol
