2018-10-15Refactor host.ConnectedEndpointIan Gudger
* Integrate recvMsg and sendMsg functions into Recv and Send respectively as they are no longer shared. * Clean up partial read/write error handling code. * Re-order code to make sense given that there is no longer a host.endpoint type.

2018-10-15Merge host.endpoint into host.ConnectedEndpointIan Gudger
host.endpoint contained duplicated logic from the sockerpair implementation and host.ConnectedEndpoint. Remove host.endpoint in favor of a host.ConnectedEndpoint wrapped in a socketpair end. PiperOrigin-RevId: 217240096 Change-Id: I4a3d51e3fe82bdf30e2d0152458b8499ab4c987c
2018-10-10Enforce message size limits and avoid host calls with too many iovecsMichael Pratt
Currently, in the face of FileMem fragmentation and a large sendmsg or recvmsg call, host sockets may pass > 1024 iovecs to the host, which will immediately cause the host to return EMSGSIZE. When we detect this case, use a single intermediate buffer to pass to the kernel, copying to/from the src/dst buffer. To avoid creating unbounded intermediate buffers, enforce message size checks and truncation w.r.t. the send buffer size. The same functionality is added to netstack unix sockets for feature parity.

host.endpoint already has the check, but it is missing from host.ConnectedEndpoint. PiperOrigin-RevId: 214962762 Change-Id: I88bb13a5c5871775e4e7bf2608433df8a3d348e6

2018-05-16Release mutex in BidirectionalConnect to avoid deadlock.Brian Geffon
When doing a BidirectionalConnect we don't need to continue holding the ConnectingEndpoint's mutex when creating the NewConnectedEndpoint as it was held during the Connect. Additionally, we're not holding the baseEndpoint mutex while Unregistering an event. PiperOrigin-RevId: 196875557 Change-Id: Ied4ceed89de883121c6cba81bc62aa3a8549b1e9
