Hello,

Our upstream systemd-networkd testsuite[0] managed to hit a NULL pointer dereference in the macsec driver on Arch Linux on kernel 5.7.2, filed as [1]. After minimizing the reproducer, I tried on Fedora Rawhide with 5.8.0-0.rc2.20200623gitdd0d718152e4.1 and apart from the original NULL pointer dereference, there's also "kernel: BUG: sleeping function called from invalid context at include/linux/percpu-rwsem.h:49":
