CORBA34 — Change new GIOP Negotiate Session Message to Firewall Specific

  • Key: CORBA34-23
  • Legacy Issue Number: 6285
  • Status: closed  
  • Source: Syracuse University ( Polar Humenn)
  • Summary:

    Here is a small proposal for GIOP 1.4 with Firewall and Bidirectional. We
    would get rid of all the weird nasty service contexts and make it
    simplistic. The FireWall messages are only allowed before any other GIOP
    messages. BiDir messages can happen at any time according to their
    protocol.

    What do you think? Asside from some problems I see with BiDir
    offer/challenge/response correlation, it is essentially equivalent to the
    solution proposed in the adopted spec.

    module GIOP {
    enum MsgType_1_4

    { Request, Reply, CancelRequest, LocateRequest, LocateReply, CloseConnection, MessageError, Fragment, // GIOP 1.1 addition // GIOP 1.4 additions FirewallPathRequest, // 8 FirewallPathRepsonse, // 9 BiDirOffer, // 10 BiDirChallenge, // 11 BiDirResponse // 12 }

    ;

    // Firewall Traversal GIOP 1.4

    struct FirewallSpec

    { boolean is_intelligent; IOP::TaggedComponentSeq endpoints; }

    ;
    typedef sequence<FirewallSpec> FirewallPath;

    struct FirewallPathRequestHeader

    { unsigned long host_index; FirewallPath path; }

    ;
    // No body follows.

    enum FirewallPathResponseStatusType

    { NO_EXCEPTION, SYSTEM_EXCEPTION }

    ;

    struct FirewallPathResponseHeader

    { FirewallPathResponseStatusType status; boolean connection_complete; }

    ;
    // Marshalled body immediately follows

    // Bidirectional GIOP 1.4

    // To keep this file uncomplicated we can introduce the
    // headers and put the marshalled bodies in a separate BiDir module
    // Due due some issue about the challege/response protocol for this,
    // there may be a need of an offer_id to correlate them.

    struct BiDirOfferHeader

    { unsigned long offer_id; };
    // Marshalled body immediately follows.


    struct BiDirChallengeHeader { unsigned long offer_id; }

    ;
    // Marshalled body immediately follows.

    struct BiDirResponseHeader

    { unsigned long offer_id; }

    ;
    // Marshalled body immediately follows.
    };
