The\n\u0027subflow_req-\u003emsk\u0027 ownership is transferred to the subflow the first,\nand there will be a risk of a null pointer dereference here.\n\nThis patch fixes this issue by moving the \u0027subflow_req-\u003emsk\u0027 under the\n`own_req == true` conditional.\n\nNote that the !msk check in subflow_hmac_valid() can be dropped, because\nthe same check already exists under the own_req mpj branch where the\ncode has been moved to.",
