Kuniyuki IwashimaandGreg Kroah-Hartman fcaef69c79 udp: Fix a data-race around sysctl_udp_l3mdev_accept. 
[ Upstream commit 3d72bb4188 ]

While reading sysctl_udp_l3mdev_accept, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its reader.

Fixes: 63a6fff353 ("net: Avoid receiving packets with an l3mdev on unbound UDP sockets")
