Vulnerability/mitigation tester for Linux-kernel CVE-2026-98432
This is a test program for Linux-kernel CVE-2026-98432. Aim it at a box to see whether IP-option-enabled SYN packets are responded to or blackholed. I haven't got RecordRoute mode to make sense yet but MptcpBare and MptcpKeys worked well to test my infrastructure before and after mitigation.
