Description
Steps to reproduce:
echo 0542073208036e646e080962726f6164636173740820$(makepasswd | openssl sha256 | awk '{print $2}')090214000a0483a975840c021388 \ | xxd -r -p | nc hobo.cs.arizona.edu 6363
This injects a malformed packets of structure:
Interest Name GenericNameComponent ndn GenericNameComponent broadcast GenericNameComponent [RANDOM] Selectors MetaInfo (empty) Nonce 0x83a97584 InterestLifetime 5000
Expected: NFD drops the malformed packet.
Actual: persistent Interest loop occurs across the testbed.
This was observed on global testbed on 04 Sep 2019. Steps above were developed according to captured packet samples.
