Problem: glb-redirect sinks ICMP Packet Too Big messages, breaking Path MTU Discovery
Problem: glb-redirect sinks ICMP Packet Too Big messages, breaking Path MTU Discovery: a task in LegoFlow-SWE (Harbor dataset). The glb-redirect proxy chain incorrectly handles ICMP and ICMPv6 packets that carry Path MTU Discovery (PMTUD) information. When an ICMP Packet Too Big (PTB) message…
The task
The `glb-redirect` proxy chain incorrectly handles ICMP and ICMPv6 packets that carry Path MTU Discovery (PMTUD) information. When an ICMP Packet Too Big (PTB) message arrives at the first proxy hop, the system accepts and processes it locally instead of forwarding it to the correct downstream hop. This prevents…
