Tuning Linux's ipv6 stack

Question

I'm working on a Linux network deice, and there are some tcp/ip settings that don't seem to have ipv6 equivalents. IP forwarding is a common setting, and available in both stacks

net.ipv4.ip_forward
net.ipv6.conf.all.forwarding

But these are examples of some setting I would need to support ipv6

net.ipv4.ip_nonlocal_bind
net.ipv4.ip_local_port_range
net.ipv4.tcp_tw_reuse
net.ipv4.tcp_rmem
net.ipv4.tcp_wmem

ip_nonlocal_bind is pretty critical, and settings for tcp TIME_WAIT sockets are seemingly missing.

Pointers to kernel/iproute documentation which I may have missed would be great too.

Answer 1

Well, it seems that at least some (all?) of these features just haven't been implemented.

Here is a recent attempted patch to add ipv6_nonlocal_bind, with some issues later in the thread.
