When a kernel is built with virtio-vsock we encounter a kernel panic in our init script, while trying to read entropy from the host. Parsing through the boot logs, it seems like the hv_sock transport is not being initialized: ``` [ 0.712310] NET: Registered PF_VSOCK protocol family [ 0.716225] hv_vmbus: registering driver hv_sock [ 0.719551] hv_vmbus: unregistering driver hv_sock [ 0.723281] IPI shorthand broadcast: enabled ``` Disabling `virtio_vsock_init` seems to fix the problem: ``` [ 0.829397] NET: Registered PF_VSOCK protocol family [ 0.831728] initcall virtio_vsock_init blacklisted [ 0.835999] hv_vmbus: registering driver hv_sock [ 0.837906] IPI shorthand broadcast: enabled ``` For kernels built without virtio-vsock, skipping `virtio_vsock_init` is a no-op: ``` [ 0.539320] NET: Registered PF_VSOCK protocol family [ 0.541417] hv_vmbus: registering driver hv_sock [ 0.549999] IPI shorthand broadcast: enabled ``` Signed-off-by: Maksim An <maksiman@microsoft.com> (cherry picked from commit 914512d)
