Hi. This is an attempt to implement the ability to read socket's queue without removing skbs from it. Using MSG_PEEK doesn't work for unix sockets, both dgram and stream. The proposal is to implement the SO_PEEK_OFF sockopt which specifies an offset in bytes where to start peeking the data from. I've already sent an example of how this can look, and since nobody objected about the concept itself, here's the "official" v1. This includes all the unix socket types and (hopefully) addresses locking issues David pointed out.
