2999a090b7 Fixed the client, now the payload shrinking is fully working, also the bug previously found seems to be nothing but an error of mine. Ready to merge! 2021-11-27 19:08:38 -05:00

a1119894cd Made it work with an arbitrary length payload. Generalization with constants.h, now the PoC can be used for any shrinking/enlarging value. Discovered a very curious bug 2021-11-27 17:01:10 -05:00

442f955cf5 Added module which arbitrarily increases the size of the packet we received. Needs some tweaking to allow for modification of the header and payload fields yet, but the space allocation is already there. Also, multiple improvements overall 2021-11-24 20:41:07 -05:00
