From 83cd5eb654b320c1972254f243531f3f3cebcccf Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 12 Sep 2023 16:02:10 +0000 Subject: ipv6: lockless IPV6_ROUTER_ALERT_ISOLATE implementation Reads from np->rtalert_isolate are racy. Move this flag to inet->inet_flags to fix data-races. Signed-off-by: Eric Dumazet Reviewed-by: David Ahern Signed-off-by: David S.
