From d2f011a0bf28c090ad75c9b1d306f2e1dda1c9bc Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Fri, 8 Dec 2023 10:12:43 +0000 Subject: ipv6: annotate data-races around np->mcast_oif np->mcast_oif is read locklessly in some contexts. Make all accesses to this field lockless, adding appropriate annotations. This also makes setsockopt( IPV6_MULTICAST_IF ) lockless.
