> Commit dcd87999d415 ("igmp: net: Move igmp namespace init to correct file")
> moved the igmp sysctls initialization from tcp_sk_init to igmp_net_init. This
> function is only called as part of per-namespace initialization, only if
> CONFIG_IP_MULTICAST is defined, otherwise igmp_mc_init() call in ip_init is
> compiled out, casuing the igmp pernet ops to not be registerd and those sysctl
> being left initialized with 0. However, there are certain functions, such as
> ip_mc_join_group which are always compiled and make use of some of those
> sysctls. Let's do a partial revert of the aforementioned commit and move the
> sysctl initialization into inet_init_net, that way they will always have
> sane values.

Please do not use "CC: stable.." for networking patches, I take care of
-stable submissions by hand for those.
Applied and queued up for -stable, thanks.
