If the trapping instruction contains a ':', for a memory access through segment registers for example, the sed substitution will insert the '*' marker in the middle of the instruction instead of the line address: 2b: 65 48 0f c7 0f cmpxchg16b %gs:*(%rdi) <-- trapping instruction I started to think I had forgotten some quirk of the assembly syntax before noticing that it was actually coming from the script. Fix it to add the address marker at the right place for these instructions: 28: 49 8b 06 mov (%r14),%rax 2b:* 65 48 0f c7 0f cmpxchg16b %gs:(%rdi) <-- trapping instruction 30: 0f 94 c0 sete %al Fixes: 18ff44b189e2 ("scripts/decodecode: make faulting insn ptr more robust") Signed-off-by: Ivan Delalande <colona@arista.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Reviewed-by: Borislav Petkov <bp@suse.de> Link: http://lkml.kernel.org/r/20200419223653.GA31248@visor Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
