Hi, Here are 2 bugfixes for the x86/kprobes, [1/2] fixes an old bug which tries to find instruction prefixes in insn->opcode (which should be never found) and misusing insn->attr. [2/2] fixes a new bug found by Coverity in the recent commit 6256e668b7 ("x86/kprobes: Use int3 instead of debug trap for single-step"). To fix the 2nd one, [2/2] also cleanup the switch-case with range cases, because that is much more clear what is not boostable. Thank you, --- Masami Hiramatsu (2): x86/kprobes: Fix to check non boostable prefixes correctly x86/kprobes: Fix to identify indirect jmp and others using range case arch/x86/kernel/kprobes/core.c | 57 +++++++++++++++++++++------------------- 1 file changed, 30 insertions(+), 27 deletions(-) -- Masami Hiramatsu (Linaro) <mhiramat@xxxxxxxxxx>
