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: [email protected]
Reporter: [email protected]
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.
