https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=260120 Bug ID: 260120 Summary: [sctp] DSCP/TOS not always set during an association establishment (IPv6) Product: Base System Version: 13.0-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: albin.hellqvist@ericsson.com Created attachment 229796 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=229796&action=edit Pcaps for different DSCP/TOS scenarios It seems like the DSCP/TOS field isn't getting set for INIT_ACK (but is for COOKIE_ACK) when establishing an SCTP association (IPv6). This works for IPv4 however. I have made a summary here: FreeBSD 12.2: IPv4 TCP: Working IPv6 TCP: Not working IPv4 SCTP: Working IPv6 SCTP: Not working FreeBSD 13.0: IPv4 TCP: Working IPv6 TCP: Working IPv4 SCTP: Working IPv6 SCTP: Not working Linux: IPv4 TCP: Working IPv6 TCP: Working IPv4 SCTP: Working IPv6 SCTP: Working I haven't tested this for the FIN/SHUTDOWN phase. -- You are receiving this mail because: You are the assignee for the bug.
