Description

In the Linux kernel, the following vulnerability has been resolved: igmp: Fix data-races around sysctl_igmp_qrv. While reading sysctl_igmp_qrv, it can be changed concurrently. Thus, we need to add READ_ONCE() to its readers. This test can be packed into a helper, so such changes will be in the follow-up series after net is merged into net-next. qrv ?: READ_ONCE(net->ipv4.sysctl_igmp_qrv);
