    Extend RPC protocol to allow FD passing · b0f996a6
    Daniel P. Berrange 提交于
    Define two new RPC message types VIR_NET_CALL_WITH_FDS and
    VIR_NET_REPLY_WITH_FDS. These message types are equivalent
    to VIR_NET_CALL and VIR_NET_REPLY, except that between the
    message header, and payload there is a 32-bit integer field
    specifying how many file descriptors have been passed.
    
    The actual file descriptors are sent/recv'd out of band.
    
    * src/rpc/virnetmessage.c, src/rpc/virnetmessage.h,
      src/libvirt_private.syms: Add support for handling
      passed file descriptors
    * src/rpc/virnetprotocol.x: Extend protocol for FD
      passing
