Martine S. Lenders a7d468988d sock: amend with zero-copy receive functions ... This change amends the `sock` API by a set of functions to `sock` that allow provisioning of stack-internal buffers to the caller on receive. This allows to cover two use-cases 1. Zero-copy systems: if the stacks supported the buffer space provided by these functions can be the same that was filled in the link-layer 2. asynchronous receive within a wrapping sock layer (e.g. `sock_dtls` wrapping `sock_udp`): to receive packets of the lower level protocol asynchronously, the wrapping implementation layer would currently need to allocate its own buffer space, introducing a third buffer space in addition to the one of the application and the network stack. For a wrapping layer this is undesirable. While there are security considerations exposing stack internal memory space to the caller, I believe they are minor, as in the end the application developer is the person in control of the node.		2020-03-24 14:02:36 +01:00
