Jiapeng,
Aurelien is correct, you should respin this patch and correct for
where it breaks the sizeof calculation. For example your change:
struct smb2_lock_rsp {
@@ -1434,7 +1434,7 @@ struct smb2_query_directory_req {
__le16 FileNameOffset;
__le16 FileNameLength;
__le32 OutputBufferLength;
- __u8 Buffer[1];
+ __u8 Buffer[];
} __packed;
would have the side effect of making the file name off by one:
smb2pdu.c-4654- req->FileNameOffset =
smb2pdu.c:4655: cpu_to_le16(sizeof(struct
smb2_query_directory_req) - 1);
