Bug description:
[Impact]
The initialization of the entropy buffer of the urandom device is critical
for security.
[Test case]
When booting Jammy 22.04.1 on QEMU riscv64 I see the following warnings:
[ 14.654546] random: lvm: uninitialized urandom read (4 bytes read)
[ 15.247995] random: lvm: uninitialized urandom read (2 bytes read)
[ 22.484719] random: lvm: uninitialized urandom read (4 bytes read)
[ 43.161846] random: lvmconfig: uninitialized urandom read (4 bytes read)
[ 48.862281] random: lvm: uninitialized urandom read (4 bytes read)
Module virtio-rng.ko is missing in initrd.img.
Adding virtio_rng to /etc/initramfs-tools/modules avoids the warnings.
Hardware RNG drivers should generally be included in the initrd to
provide early entropy.
Best regards
Heinrich
