Major rewrite of the protocol framework - changes not yet complete Common ------ - Change in OstProto - Individual protocols are now extensions of (new) message 'Protocol' instead of 'Stream' - Stream now contains a repeated Protocol which also determines the ordered set of currently selected protocols; StreamCore.frame_proto which was doing this earlier has been removed - Change in AbstractProtocol Interface - Parent changed to StreamBase - Corresponding change in constructor and factory func - createInstance() - new method protocolNumber() - returns unique id for each protocol - protoDataCopyInto/From() now copies into OstProto::Protocol instead of OstProto::Stream - Change in all subclasses of AbstractProtocol to match new interface - For all protocols, configFrom is no longer static, but each protocol has its own configForm - configForm creation is lazy - configForm is still a child of the protocol i.e. it will be destroyed alongwith the protocol - TODO: convert configWidget() to a pure factory function i.e. the protocol does not own the configForm - this requires us to pass the widget into load/storeConfigWidget() methods - ProtocolCollection class removed alongwith its .h and .cpp - ProtocolList class redefined to serve the purpose of ProtocolCollection - New class ProtocolListIterator defined to iterate ProtocolList - AbstractProtocol methods now use the ProtocolListIterator - Factory function createProtocol() added to ProtocolManager - OstProto::StreamCore accessor functions moved from Stream to StreamBase Server ------ - MyService uses the newly moved accessors to StreamBase for OstProto::StreamCore members - StreamInfo now uses the protocols to create the packet Client ------ - StreamConfigDialog now uses ProtocolListIterator - So does PacketModel

Protocol Framework related -------------------------- - AbstractProtocol Constructor and Factory function now take an optional (default NULL) "parent" abstract protocol in addition to the stream; this "parent" protocol is non-NULL for protocols which are aggregated in a ComboProtocol - All subclasses of AbstractProtocol modified as per the above interface change - ProtocolManager also modifed as per the above interface change - new data members in AbstractProtocol - prev, next; the AbstractProtocol implementation now uses these members to traverse protocols on the list instead of ProtocolListIterator; this change required for ComboProtocol - ProtocolListIterator updates these new members - prev/next on insert/remove/replace - ComboProtocol and ProtocolListIterator classes made friends of AbstractProtocol - ComboProtocol implemented as a template class (completed) - Dot2LLc implemented as a combo of Dot3Raw and LLC - Dot2Snap implemented as a combo of Dot2Llc and SNAP - VlanStack implemented as a combo of VLAN + VLAN - ProtocolManager now uses the ProtocolId enums rather than hardcoded values Stream Config Dialog -------------------- - "None" radio button added to all protocol levels - Protocol Level 1 added with 'mac' as the only valid protocol in the "simple" mode widget - With Dot2Llc, Dot2Snap and VlanStack implemented as "combo" protocols, the protocol choice radiobuttons in the "simple" mode are now 1:1 with a protocol; this has the following implications/advantages: - Updates of the "simple" mode widget from/to stream's protocolList is simpler; this code has now been rewritten to take advantage of 1:1 - This paves the way for exporting tunneled protocols 4over4, 4over6, 6over4 etc. in the "simple" mode - This should also (hopefully) require less changes when adding a new protocol; more work needs to be done to reach this goal Fixes ----- - Dot3Protocol now derives "length" correctly for VLAN tagged packets - StreamBase now uses the ProtocolListIterator to append the default protocols in a stream instead of directly manipulating ProtocolList; also in protoDataCopyFrom() Others (Client/Server) ---------------------- - Port Packet Capture implemented; "view capture" is pending (hack put in place now for testing)

Protocol Framework basic code in place now. Cleanup pending. - New Classes: o ProtocolManager - singleton with which all protocols register o ProtocolCollection - Aggregates all registered protocols; exports methods to work on all protocols o StreamBase - aggregates ProtocolCollection with Stream Core and Control; the client/server side stream classes now derive from StreamBase leading to major reduction in their code (more cleanup pending) - AbstractProtocol now supports the additional methods o createInstance() o protocolFrameSize() o protocolFrameOffset(), protocolFramePayloadSize() o protocolId(), payloadProtocolId() o protocolFrameCksum(), protocolFramePayloadCksum() 0 constructor takes an extra param - frameProtoList - Specific protocols - eth2, llc, snap, ip4, udp, tcp now return length, protocol id and cksums correctly (tcp/udp cksum pending) - StreamConfigDialog - protocol controls for length, cksum and protocolid are automatically updated (not fully working yet)

- AbstractProtocol - new method: fieldFlags() - isCksum, isMeta; Note: isMeta is a flag now not a attrib - fieldData() bit fields are now in lsb not msb - protocolFrameValue() and subclasses changed accordingly - protocolFrameValue() now takes an additional bool param indicating whether the frameValue is being requested for a checksum calculation; if so fields which are checksum fields are assumed to be zero and their value is not fetched to prevent infinite recursion - Other Protocols - mac: srcMac/dstMac modes is now working - vlan: implemented VLAN protocol - ip4: src/dst Addr modes is now working - udp/tcp: checksum done - Basic testing done for MAC, VLAN, IPv4, UDP and TCP protocols - sample protocol: .cpp/.h added to repos - need to be made compilable - StreamConfigDialog - Redesigned the protocol selection tab to accomodate "Advanced Protocol Selection" - L2 Tab config widgets are now in 2 columns - Packet Tree View is no longer collapsed if selected protocols don't change

Refactoring, optimization et. al. --------------------------------- - StreamConfigDialog: Valid subsequent protocol choices for a particular protocol in the simple protocol selection widget is no longer hardcoded - ProtocolManager is queried for validitity of each pair of possible protocols; signal-slot connections are made accordingly. This refactoring makes it easier to add a protocol to the simple protocol selection widget - ProtocolManager: populates and maintains a database of valid 'neighbour protocols' and implements a method - isValidNeighbour() to query the same for a pair of protocols - AbstractProtocol: new method protocolIdType() introduced to build the above database (in conjunction with the existing method protocolId(ProtocolIdType)); default implementation returns ProtocolIdNone - Protocols which include a valid/supported ProtocolIdType (eth/llc/ip) reimplement protocolIdType() to return the apporpirate ProtocolIdType. These are viz. - combo - eth - llc - snap - ip - Speed optimization while populating streamqueues if the protocolFrameValue/Size() does not vary across packets - AbstractProtocol: new methods to support the above optimization - isProtocolFrameValueVariable() - isProtocolFrameSizeVariable() - isProtocolFramePayloadValueVariable() - isProtocolFramePayloadSizeVariable() (each of the default implementations returns false indicating that the protocol frame value or frame size is fixed and not variable) - Protocols which support variable values/size (list follows) reimplement the above methods appropriately - combo - mac - dot3 - ip4 - tcp - udp - payload - StreamInfo::makePacket() moved to base class as StreamBase::frameValue() - StreamBase: all 'get' accessor functions made 'const' - class ProtocolManager: while registering a protocol, no need to pass the protocol name; ProtocolManager finds it out internally by using the protocol's shortName() method Fixes ----- - Fixed issue with port capture not starting the first time 'start capture' was clicked
