I’m using setsockopt to set the traffic class on sending and receive
it in control messages on receiving, for both IPv4 and IPv6.
The relevant documentation is the ip(7) manpage and, because the ipv6(7)
manpage doesn’t contain it, RFC3542.
For the receiving side, the corresponding socket options are:
• IPPROTO_IP ⇒ IP_RECVTOS, with an int argument 1 (as in the manpage)
• IPPROTO_IPV6 ⇒ IPV6_TCLASS, with an int argument 1 (as in the RFC)
The receiving CMSG is then supposed to contain the traffic class octet
as first byte in the corresponding CMSG_DATA:
IP_RECVTOS (since Linux 2.2)
If enabled, the IP_TOS ancillary message is passed with incoming
packets. It contains a byte which specifies the Type of Ser‐
vice/Precedence field of the packet header.
… and…
In the cmsghdr structure containing this ancillary data, the
cmsg_level member will be IPPROTO_IPV6, the cmsg_type member will be
IPV6_TCLASS, and the first byte of cmsg_data[] will be the first byte
of the integer traffic class.
However, Linux has net/ipv6/datagram.c…
int tclass = ipv6_get_dsfield(ipv6_hdr(skb));
put_cmsg(msg, SOL_IPV6, IPV6_TCLASS, sizeof(tclass), &tclass);
… and net/ipv6/ipv6_sockglue.c…
int tclass = (int)ip6_tclass(np->rcv_flowinfo);
put_cmsg(&msg, SOL_IPV6, IPV6_TCLASS,
sizeof(tclass), &tclass);
… both setting them as int, breaking standards/documentation-compliant
code on all big endian platforms. Same in net/ipv4/ip_sockglue.c…
int tos = inet->rcv_tos;
put_cmsg(&msg, SOL_IP, IP_TOS, sizeof(tos), &tos);
… in one place, but…
put_cmsg(msg, SOL_IP, IP_TOS, 1, &ip_hdr(skb)->tos);
… in ip_cmsg_recv_tos(), yielding inconsistent results for IPv4(!).
For the sending side, we use:
• IPPROTO_IP, IP_TOS, with an argument…
• IPPROTO_IPV6, IPV6_TCLASS, with an argument…
This is funny. The documentation says to use a byte for IPv4…
IP_TOS (since Linux 1.0)
Set or receive the Type-Of-Service (TOS) field that is sent with
every IP packet originating from this socket. It is used to
prioritize packets on the network. TOS is a byte. There are
… and setsockopt works with a byte argument, but for IPv6, using a
byte causes EINVAL (but this is because RFC3542 says int, overriding
the itojun draft which said byte).
Looking at the kernel code, IP_TOS indeed reads a byte if the size
given is less than 4, an int otherwise… except bpf_setsockopt, which
expects an int. OK, should be no problem for my userspace code.
IPV6_TCLASS always expects an int. Unexpected but apparently okay
wrt. the documentation.
tl;dr: Receiving traffic class values from IP traffic is broken on
big endian platforms.
I place the following suggestion for discussion, to achieve maximum
portability: put 4 bytes into the CMSG for both IPv4 and IPv6, where
the first and fourth byte are, identically, traffic class, second and
third 0.
Please forward this upstream. Thanks!
