In layered architectures, each lower layer * encapsulates data from its upper layer - that is it * treats the data from its upper layer as payload and prepends an own header to the packet, * which - again - is treated as the payload for the layer below. The figure below is an * example for how such a data frame is composed out of packets, e.g. when sending a mail. * * <pre> * | User Data | == Mail Data @@ -95,72 +97,75 @@ class QSocketNotifier; * encapsulation level varies and can't be deduced without actually looking into the packets. * * For actually working with captured frames, it's useful to identify the packets via names and * insert them into a parent/child - relationship based on the encapsulation. This is why * all packet classes derive from QObject. The amount of overhead caused by the QObject is * not a problem in this case, because we're talking about a theoratical maximum of about * 10 packets per captured frame. We need to stuff them into a searchable list anyway and the * QObject also cares about destroying the sub-, (child-) packets. * * This enables us to perform a simple look for packets of a certain type: * @code * OPacketCapturer* pcap = new OPacketCapturer(); * pcap->open( "eth0" ); * OPacket* p = pcap->next(); * OIPPacket* ip = (OIPPacket*) p->child( "IP" ); // returns 0, if no such child exists * odebug << "got ip packet from " << ip->fromIPAddress().toString() << " to " << ip->toIPAddress().toString() << oendl; * */ class OPacket : public QObject { Q_OBJECT friend class OPacketCapturer; + friend QTextStream& operator<<( QTextStream& s, const OPacket& p ); public: OPacket( int datalink, packetheaderstruct, const unsigned char*, QObject* parent ); virtual ~OPacket(); timevalstruct timeval() const; int caplen() const; int len() const; QString dump( int = 32 ) const; void updateStats( QMap<QString,int>&, QObjectList* ); private: - void dumpStructure( QObjectList* ); - QString _dumpStructure( QObjectList* ); + QString dumpStructure() const; + QString _dumpStructure( QObjectList* ) const; private: const packetheaderstruct _hdr; // pcap packet header const unsigned char* _data; // pcap packet data const unsigned char* _end; // end of pcap packet data }; +QTextStream& operator<<( QTextStream& s, const OPacket& p ); + /*====================================================================================== * OEthernetPacket - DLT_EN10MB frame *======================================================================================*/ class OEthernetPacket : public QObject { Q_OBJECT public: OEthernetPacket( const unsigned char*, const struct ether_header*, QObject* parent = 0 ); virtual ~OEthernetPacket(); OMacAddress sourceAddress() const; OMacAddress destinationAddress() const; int type() const; private: const struct ether_header* _ether; }; /*====================================================================================== * OPrismHeaderPacket - DLT_PRISM_HEADER frame *======================================================================================*/ |
