--------------------------
- 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)
---------
- all protocols on allocation of a configWidget, also populate it before returning from configWidget()
- VLAN TPID override is now correctly saved and restored from/to its widget (vlan.cpp)
- Payload protocol returns a minimum frame value of 1 byte size (Hack to avoid crash in stream config dialog when sum of all protocol frame sizes is greater than the frame length
- small layout changes in mac widget (mac.ui)
- src/dst ip mask changed from 255.255.255.255 to 255.255.255.0 (ip4.proto)
- src mac changed from u32 to u64 (mac.proto)
- "Combo Protocol" protocol container introduced to define newer protocols as a combination of existing protocols e.g. dot2 = dot3 + llc - THIS IS NOT YET COMPLETE (comboprotocol.h)
Client/StreamConfigDialog
-------------------------
- Advanced Protocol Selection implemented
- Simple Protocol Selection rewritten to work alongside Advanced
- Payload Widget is treated like any other protocol - hence it is not placedinto the dialog specially
- Any protocol selection change (in Simple/Advanced mode) immediately triggers change in the Stream's protocolList
- Protocol Widgets now are arranged in a toolBox on a top level tab of the dialog instead of a nested tabWidget
- Vlan selection (Simple Mode) uses Radio buttons instead of checkboxes
- Double Tagged (SVlan + CVlan) now works via Simple Mode
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
- 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)
