Subject: [PATCH stable 4.9 v2 06/29] ipv6: export ip6 fragments sysctl to unprivileged users
Date: Wed, 10 Oct 2018 12:29:54 -0700 [thread overview]
Message-ID: <20181010193017.25221-7-f.fainelli@gmail.com> (raw)
In-Reply-To: <20181010193017.25221-1-f.fainelli@gmail.com>
From: Eric Dumazet <edumazet@google.com>
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
