Changes for version 3.20 - 2006-11-12

  • NEW: support for PPPoE, PPP, PPPLCP, LLC, and begin the work for CDP
  • NEW: Frame->new can now return an array ref of decoded frames, to handle new layers, and such things as IPv6 within IPv4. See doFrameReturnList from Env. With this new scheme, the behaviour from unpacking VLAN or ICMPv4 has changed. Old behaviour remains the same, but if you set doFrameReturnList to true (not by default), your programs will need updating.
  • NEW: all layers: be able to create layers without having the need to build a full frame
  • new: Frame: print() and dump() methods, encapsulate attribute
  • new: Consts: new constants
  • new: Layer: isLayer2(), isLayer3(), isLayer4(), isLayer7(), getPayloadLength()
  • new: Utils: debugDeviceList()
  • new: Env: doFrameReturnList, noFramePadding, doIPv4Checksum, noFrameComputeChecksums, noFrameComputeLengths, doMemoryOptimizations
  • update: all layers: rewrite of print() methods
  • update: TCP: optimizations on recv() method
  • removed: Frame: noPadding attribute, moved to Env noFramePadding
  • removed: Frame: doChecksum attribute, moved to Env doIPv4Checksum
  • bugfix: Env: in getSubnet()
  • bugfix: Env: mapping between dnet interface and WinPcap interface should now work
  • bugfix: Env: no IPv6 under Windows for now
  • bugfix: ETH: in isTypeIp()
  • bugfix: Frame: do not use Dump and Desc if they do not exist
  • bugfix: Frame: getFilter() only when a Frame is competely filled
  • bugfix: IPv4: do not use l4 if it does not exist
  • bugfix: IPv6: do not use l4 if it does not exist
