The only insn which could have both UPROBE_FIX_IP and UPROBE_FIX_CALL was 0xe8 "call relative", and now it is handled by branch_xol_ops. So we can change default_post_xol_op(UPROBE_FIX_CALL) to simply push the address of next insn == utask->vaddr + insn.length, just we need to record insn.length into the new auprobe->def.ilen member. Note: if/when we teach branch_xol_ops to support jcxz/loopz we can remove the "correction" logic, UPROBE_FIX_IP can use the same address. Signed-off-by: Oleg Nesterov <oleg@redhat.com> |
