SO_VM_SOCKETS_BUFFER_SIZE might have been useful for VMCI-specific applications, but we should use SO_RCVBUF and SO_SNDBUF for portable applications in the future. Those socket options also work with other address families. I guess these sockopts are bypassed by AF_VSOCK because it doesn't use the common skb queuing code in net/core/sock.c:(. But one day we might migrate to it... Stefan
+1, we should really consider to reuse the exist socket mechanism instead of re-inventing wheels.
Thanks
