What it is

In the Linux kernel, the following vulnerability has been resolved:

netfilter: bridge: eb_tables: close module init race

sashiko reports for unrelated patch:

Does the core ebtables initialization in ebtables.c suffer from a similar race?

Once nf_register_sockopt() completes, the sockopts are exposed globally.

sockopt has to be registered last, just like in ip/ip6/arptables.
