https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=243231 Bug ID: 243231 Summary: TCP/ECN - RFC3168 specifies retransmissions not to be marked ECT in the IP header Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: rscheff@gmx.at While investigating the interaction between ECN and RTO, I noticed that FBSD sends out retransmissions on ECN-enabled flows with the ECT0 codepoint in the IP header - which is only permissible with ECN++ (work in progress as IETF draft). This is not a critical deviation from the specs, only a lack of conformance. -- You are receiving this mail because: You are the assignee for the bug.help
