louxiu 3c4dfed08a Fix handle of ByteBuf with multi nioBuffer in EpollDatagramChannel and KQueueDatagramChannel ... Motivation: 1. special handling of ByteBuf with multi nioBuffer rather than type of CompositeByteBuf (eg. DuplicatedByteBuf with CompositeByteBuf) 2. EpollDatagramUnicastTest and KQueueDatagramUnicastTest passed because CompositeByteBuf is converted to DuplicatedByteBuf before write to channel 3. uninitalized struct msghdr will raise error Modifications: 1. isBufferCopyNeededForWrite(like isSingleDirectBuffer in NioDatgramChannel) checks wether a new direct buffer is needed 2. special handling of ByteBuf with multi nioBuffer in EpollDatagramChannel, AbstractEpollStreamChannel, KQueueDatagramChannel, AbstractKQueueStreamChannel and IovArray 3. initalize struct msghdr Result: handle of ByteBuf with multi nioBuffer in EpollDatagramChannel and KQueueDatagramChannel are ok		2017-05-26 07:56:34 +02:00
