- Queued RPC calls would cause crashes due to invalid pointers to request/response and/or controller; this has been fixed
- PbRpcController now takes ownership of request and response messages and
will delete them when it itself is being deleted
- This design mandates that request and response messages for each RPC call
have to be allocated on the heap.
- The convention for the Closure 'done' call now is to allocate and pass a
pointer to the controller object to it which will delete it after use;
this requires that controller itself be also allocated on the heap
(NOTE: this is just a convention - not mandatory)
- All existing RPC calls (in portgroup.cpp) have been changed to follow the
above convention
- Reordering of queued RPC calls has been fixed
- PortManager is now destroyed at exit; because of this fix the per port temporary capture files are auto-removed at exit
- WinPcapPort destructor no longer deletes the monitor threads because the parent class PcapPort already does it
- Capture does not automatically (and incorrectly) stop after one packet if started immediately after a View Capture operation
- User is prompted to stop transmit on a port first if he tries to apply configuration changes on a port in 'transmit' state
- OstProto service has a new method "modifyPort()"
- At port init port.isExclusive is now set using a bindconfig query (Win32 only)
- AbstractPort interface has 2 new pure virtual methods - hasExclusiveControl() and setExclusiveControl()
- PcapPort does not support this functionality (yet) so these methods return false
- WinPcapPort suppots this new functionality using bindconfig
- Port's notes (specifying Rx/Tx limitations) are now set and updated based on hasExclusiveControl()
- Presence of 'notes' on a port is indicated using a '*' after the port name in the port stats window
- The tabwidget has been removed from Port Window | Stream View Pane
- Ostinato Client has a new action in the port window's context menu for the same
- Port Icon in the Port Window is decorated based on exclusive control
- Ostinato Client
- will start the server as a child process at startup and terminate it at exit
- Ostinato Server (Drone)
- is now a system tray application
- if not able to bind to a IP/Port successfully, informs the user and exits
- the GUI is now nothing more than a TextLabel
Others
- If a getStats() request is pending, the client will not queue up any more requests till a reply is received for the pending one
- Nitpicks in the Payload protocol Widget, PortsWindow Widget
- LinkState is now updated in PortWindow as soon as a change is detected; the required minimal refactoring of the Port class usage has been done
- Fixed a compiler warning in portgrouplist.cpp
Others
- PortStatsFilter: Ui change - added left and right arrow icons
- Port State (Link/Transmit/Capture) now updated alongwith port stats
- On link state change, the port window is not updated - partial changes have been done under #if 0; needs refactoring of Port Class implementation/usage before a signal/slot for the same can be implemented
Fixes
- Fixed crash in client when connection to server is broken
- Packet Capture and Capture Buffer Retrieval now works correctly and consistently (I think!)
Others
- Minor visual changes in Ports Window
- Port Stats Window now has 'right' alignment for stats data and 'center' for state data
- Added support for retrieving the packet capture buffer from server to client (does not work consistently however - needs investigation)
- getCaptureBuffer() Rpc signature changed
- RPC: Added support in Rpc Channel (client) to queue calls
- RPC: Added support for transferring arbitrary binary data from server to client (used to get packet capture files)
- Rpc header changed - length is now 4 bytes instead of 2; there is no rsvd field any longer
Fixes
- RPC: Fix for the case when a msg is not received all at once over the socket
- StreamConfigDialog: fixed display issue in packet view for combo protocols containing meta fields
- Fixed issue with Stacked Vlan not retaining data for both CVlan and SVlan
- Fixed incorrect payload size issue with increment/decrement frame length modes
Refactoring, Cleanup etc.
- RPC: Minor code and TODOs cleanup
- Server: Minor code and TODOs cleanup
- Server: Removed unused file(s): rxtx.cpp, rxtx.h
- Server: Replaced direct use of ProtocolList with the ProtocolListIterator
- Common: Minor code and TODOs cleanup
- StreamBase::frameLen() now returns the length based on the mode/min/max and the passed in streamIndex
- AbstractProtocol interface changed for methods - protocolFrameSize(), protocolFrameOffset(), protocolFramePayloadSize() : all of them now take streamIndex as an optional param with 0 as the default value
- Protocols implementing the above methods changed accordingly
--------------------------
- 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)
