However, this adjustment\nremoved the `break` statement and led to an error logic of the flags\nwriting back at the end of this function.\n\nif (have_flags)\n    memcpy(nla_data(attr), &flags, sizeof(flags));\n    // attr should point to IFLA_BRIDGE_FLAGS NLA !!!\n\nBefore the mentioned commit, the `attr` is granted to be IFLA_BRIDGE_FLAGS.\nHowever, this is not necessarily true fow now as the updated loop will let\nthe attr point to the last NLA, even an invalid NLA which could cause\noverflow writes.\n\nThis patch introduces a new variable `br_flag` to save the NLA pointer\nthat points to IFLA_BRIDGE_FLAGS and uses it to resolve the mentioned\nerror
