From d986f52124e062753e33b6fe303be5904a997eac Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 12 Sep 2023 16:02:00 +0000 Subject: ipv6: lockless IPV6_MULTICAST_LOOP implementation Add inet6_{test|set|clear|assign}_bit() helpers. Note that I am using bits from inet->inet_flags, this might change in the future if we need more flags. While solving data-races accessing np->mc_loop, this patch also allows to implement lockless accesses to np->mcast_hops in the following patch. Also constify sk_mc_loop() argument.
