It was mentioned in #177 that the length of OFPPacketQueue may be 0 during the parsing process of OFPQueueGetConfigReply message. However, during the parsing process of OFPPacketQueue, the length variable of OFPQueueProp may also cause this question.
The text was updated successfully, but these errors were encountered:
This problem also occurs with the following code:
/ryu/ofproto/ofproto_v1_0_parser.py about line=1186
/ryu/ofproto/ofproto_v1_1_parser.py about line=3105
/ryu/ofproto/ofproto_v1_3_parser.py about line=6026
in /ryu/ofproto/ofproto_v1_3_parser.py about line=6026
If OFPQueueProp.len=0,the offset and length will no longer change and the parsing will fall into an infinite loop.
This message will put ryu into an infinite loop:
