I guess the TCP options being under "ipv4" is just a historical accident. The same options will continue having the same effect even if you use IPv6.
My understading was that the IPv4 & IPv6 stacks are completely separate -- code & function. Given the long list of separate, IPv6-specific, other-than-tcp sysctls, shared tcp tuning parameters seems odd. Digging in as close to authoritative Docs for it as I've been able to yet find, it seems that your point *is*, in fact, posed ... but as what appears to be a question https://www.kernel.org/doc/Documentation/networking/ip-sysctl.txt /proc/sys/net/ipv6/ ... Variables:IPv6 has no global variables such as tcp_*. tcp_* settings under ipv4/ alsoapply to IPv6 [XXX?]. ... There's also this very recent proposal http://www.spinics.net/lists/netdev/msg246716.html from Jiri Bohac @ SUSE Labs, Suse CZ, which proposes to introduce separate sysctls for tcp_syncookies_mss_table in *separate* net.ipv4 & net.ipv6 namespaces. He's a contributor to this list & a kernel dev as well ... perhaps he might shed some additional light. Perhaps that's "coming", rather than "is" ... -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
