e3a3a0cf1f Device Emulation (contd.): Fix frames not being truncated (introduced by recent changes in StreamBase::frameValue()); add test case for the same and add checksum/error check to pktlentest(s) 2016-01-27 20:39:54 +05:30

ad866e3025 Bugfix: Fix incorrect IPv4 pseudo-header checksum calculation for a stream with incrementing/decrementing packet length (regression bug caused by variable fields feature introduced in 0.7) 2016-01-27 18:26:49 +05:30

f1ff9e2616 Device Emulation (contd.) - StreamBase::frameValue() now returns truncated packet content and length instead of bailing out if the passed in buffer size is less than the packet length. This is useful for some of the device emulation code which needs packet content only uptil the IP header but not beyond, so we don't need to unnecessarily create the entire packet with payload for these cases 2016-01-15 09:37:43 +05:30

71d04b63bc Feature (contd.): Device Emulation - refactored and moved EncapEmulation as a native field of DeviceGroup instead of a extension - now the device_count comment of "per encap" makes more sense with encap at the same level as device_count 2015-12-16 20:48:17 +05:30

f8d5cbd252 Bugfix: Fixed frameVariableCount() for the stream when it doesn't contain the payload protocol and is configured to generate increment/decrement/random length packets

Srivats P
9302e5f17c Feature (contd.): Device Emulation - added resolveNeighbors() and related RPC code and implementation to send out ARP Requests and build the ARP Table on each device 2015-11-04 18:50:08 +05:30

2cad79b87e Bugfix: A calculated UDP checksum of 0 should be set as 0xFFFF in the frame as per RFC 768. A checksum value of 0 in the frame is "special" and indicates that no checksum was calculated and hence receiver should not verify the same. This special case seems to be only for UDP, not TCP though. 
Fixes #160

246bc95c74 Feature (contd.): Device Emulation - user now configures a device group instead of a single device for easier creation of multiple devices; refactored and redistributed functionality between DeviceManager and Device; external functionality wise same as last commit; added initial code for vlans but not tested 2015-09-20 17:49:15 +05:30

022fac534c Feature (contd.): Variable Fields - fixed 2nd protocol of combo protocols not being listed and offset/mask not being calculated correctly for them via the GUI 2015-05-31 20:47:25 +05:30
Srivats P.
6bb64a3b26 Feature (contd.): Variable Fields - renamed variable_fields as singular; this makes it consistent with other repeated variables in protocol.proto and in any case the C++/Python generated code "sounds" better with a repeated field named in its singular form, rather than plural 2015-05-31 20:14:32 +05:30

641a4f3c89 Feature (contd.): Variable Fields - defined a template function varyCounter to avoid duplicating code for different counter sizes 2015-05-31 19:46:16 +05:30
Srivats P.
77f5b124e7 Feature (contd.): Variable Fields - fixed the code to use 'step' while varying fields which was missed out earlier. Updated the test suite and made sure all test cases pass 2015-05-31 18:02:06 +05:30

60c47c34a1 Feature (contd.): Variable Fields - AbstractProtocol now caches fieldFrameBitOffset unless the subclass says not to 2015-05-27 22:41:31 +05:30

4f2abcb789 Feature (contd.): Variable Fields - AbstractProtocol now caches the frameVariableCount (of variableFields) 2015-05-27 21:28:40 +05:30
Srivats P.
7a1f791a37 Feature (contd.): Variable Fields - removed protocol subclass implementations of isProtocolFrameValueVariable() since the updated implementation in the base abstract class is now sufficient. Updated subclass implementations of protocolFrameValueVariableCount() to query the base class and use the return value in its calculation 2015-05-27 20:36:49 +05:30
Srivats P.
df24cf8b15 Feature: Variable Fields - any field of any protocol can now be varied by specifying it as a generic 8/16/32 bit field at a specified offset (relative to the protocol frame value) with a certain mask and a (initial) value alongwith count and step; this is working code - but incomplete. Bunch of FIXME/TODOs and testing pending 2015-05-26 21:43:37 +05:30

a9da643fb2 Feature: Reserve Ports for cooperative use of shared drone. If a port is reserved the GUI will display the username of the owner but others can still view and control the port; in other words, we just potentially prevent unintentional usage of other people's ports, users still need to play nice with each other!

f4f5214b7a If no L4 protocol follows IPv6, set the IPv6 Next-Header field to 0x3B (IPv6-No-Next-Header) instead of leaving it at 0 which is interpreted as IPv6-Hop-By-Hop by the recipient and subsequent failure in parsing the frame 2015-01-13 18:51:21 +05:30
