    SUNRPC: Provide functions for managing universal addresses · a02d6926
    Chuck Lever authored
    Introduce a set of functions in the kernel's RPC implementation for
    converting between a socket address and either a standard
    presentation address string or an RPC universal address.
    
    The universal address functions will be used to encode and decode
    RPCB_FOO and NFSv4 SETCLIENTID arguments.  The other functions are
    part of a previous promise to deliver shared functions that can be
    used by upper-layer protocols to display and manipulate IP
    addresses.
    
    The kernel's current address printf formatters were designed
    specifically for kernel to user-space APIs that require a particular
    string format for socket addresses, thus are somewhat limited for the
    purposes of sunrpc.ko.  The formatter for IPv6 addresses, %pI6, does
    not support short-handing or scope IDs.  Also, these printf formatters
    are unique per address family, so a separate formatter string is
    required for printing AF_INET and AF_INET6 addresses.
