sys/kern uipc_socket.c
Log:
When doing a recv(.. MSG_WAITALL) for a message which is larger than
the socket buffer size, the receive is done in sections. After completing
a read, call pru_rcvd on the underlying protocol before blocking again.
This allows the the protocol to take appropriate action, such as
sending a TCP window update to the peer, if the window happened to
close because the socket buffer was filled. If the protocol is not
notified, a TCP transfer may stall until the remote end sends a window
probe.
