Diag for raw\nsockets uses the pad field in struct inet_diag_req_v2 for the\nunderlying protocol. This field corresponds to the sdiag_raw_protocol\nfield in struct inet_diag_req_raw.\n\ninet_diag_get_exact_compat() converts inet_diag_req to\ninet_diag_req_v2, but leaves the pad field uninitialized. So the issue\noccurs when raw_lookup() accesses the sdiag_raw_protocol field.\n\nFix this by initializing the pad field in\ninet_diag_get_exact_compat(). Also, do the same fix in\ninet_diag_dump_compat() to avoid the similar issue in the future.\n\n[1]\nBUG: KMSAN: uninit-value in raw_lookup net/ipv4/raw_diag.c:49 [inline]\nBUG: KMSAN: uninit-value in
