Tuning Linux's IPv6 stack

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.

Solution 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.
