In the Linux kernel, the following vulnerability has been resolved:
l2tp: close all race conditions in l2tp_tunnel_register()
The code in l2tp_tunnel_register() is racy in several ways:
It modifies the tunnel socket after publishing it.
It calls setup_udp_tunnel_sock() on an existing socket without locking.
It changes sock lock class on fly, which triggers many syzbot reports.
This patch amends all of them by moving socket initialization code before publishing and under sock lock. As suggested by Jakub, the l2tp lockdep class is not necessary as we can just switch to bh_lock_sock_nested().
