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 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
- 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)
- StreamListView now has a delegate to display a combobox for "nextWhat" and a checkbox for "status"
- StreamListView now has reasonable default widths for its columns
- Packet Transmission rate (IPG) is done - need to test. IBG is still pending
- Per port there are two pcap_t handles - one for Rx and one for Tx: since PCAP does not capture loopback packets, transmission by OST happens on Rx Hdl so that they are recieved on the Tx Hdl
- pcap_loop() changed to pcap_dispatch() to be able to work in PCAP/Linux - forgot exactly why :-)
- Removed NIC stats
- Implemented PortStatsFilterDialog ordering of ports
- PortStatsWindow - Tooltip on Port column dispays stats limitations
Frame Length Modes done.
Data Pattern Modes done.
Some minor fixes/enhancements in streamconfigdialog.
Added a "Edit Stream" action in StreamList context menu
