man ip-tunnel says default tos is 00, and that's true. If you're about *.tex
files under iproute2.git/doc, they are more than 10 years old, I doubt if they
are maintained. Otherwise I don't know where you found it.
This workaround works because setting tos=inherit disables tunnel route cache,
which is buggy in your release (it doesn't cache source address).
Btw, thanks for the report, David has accepted the patch today, commit
95cb574 (ip_tunnel(ipv4): fix tunnels with "local any remote $remote_ip"), so
I think next kernel releases will have it.
