Srivats P	a498dbf21a	Fix incorrect UDP/ICMP checksums ... For UDP encaps like VxLAN or Geneve, which can contain IP as payload, the UDP checksum was incorrect because when summing UDP payload (i.e. IP), we skipped the IPv4 checksum field, which should not be skipped in this case. Similar issue, for ICMP with IP as payload, ICMP checksum was incorrect. Essentially, any protocol which checksums over its payload and the payload contains protocols with checksum fields.	2021-09-04 18:16:40 +05:30

Srivats P	c2f36c5cb3	IPv4 now supports options - configured as a hex string for now; fixes #120	2016-10-27 23:51:55 +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
Srivats P.	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! ...
