Xin Long cca6127587 tipc: keep the skb in rcv queue until the whole data is read ... [ Upstream commit f4919ff59c ] Currently, when userspace reads a datagram with a buffer that is smaller than this datagram, the data will be truncated and only part of it can be received by users. It doesn't seem right that users don't know the datagram size and have to use a huge buffer to read it to avoid the truncation. This patch to fix it by keeping the skb in rcv queue until the whole data is read by users. Only the last msg of the datagram will be marked with MSG_EOR, just as TCP/SCTP does. Note that this will work as above only when MSG_EOR is set in the flags parameter of recvmsg(), so that it won't break any old user applications.
