4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Eric Dumazet <[email-masked]>

IPv4 was changed in commit 52a773d645e9 ("net: Export ip fragment
sysctl to unprivileged users")

The only sysctl that is not per-netns is not used :
ip6frag_secret_interval
