https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=260119 Bug ID: 260119 Summary: [sctp] Not inheriting the DSCP/TOS socket option 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 I noticed that when setting DSCP/TOS on a server socket, it doesn't get inherited to socket from accept(). This is not stated anywhere in any RFCs as far as I know, but it is not consistent with how TCP sockets behaves. There might be other socket options that are affected. I have made a summary for DSCP/TOS at least: FreeBSD 12.2: IPv4 TCP: Not inherited IPv6 TCP: Inherited IPv4 SCTP: Not inherited IPv6 SCTP: Not inherited FreeBSD 13.0: IPv4 TCP: Inherited IPv6 TCP: Inherited IPv4 SCTP: Not inherited IPv6 SCTP: Not inherited Linux (lksctp): IPv4 TCP: Inherited IPv6 TCP: Inherited IPv4 SCTP: Not inherited IPv6 SCTP: Inherited Seems like this was changed for IPV4 TCP between FreeBSD 12.2 and 13.0. I cannot find any ticket for that, but I think that the same design choice could be considered for SCTP as well. -- You are receiving this mail because: You are the assignee for the bug.home | help
