Subject: [PATCH] OvmfPkg: Rerun dispatcher after initializing virtio-rng
RH-Author: Oliver Steffen <osteffen@redhat.com>
RH-MergeRequest: 106: OvmfPkg: Rerun dispatcher after initializing virtio-rng
RH-Jira: RHEL-66188
RH-Acked-by: Gerd Hoffmann <kraxel@redhat.com>
RH-Commit: [1/1] a62e445ae8e45d656aaa2ea5f1875541e658f1d8
Since the pixiefail CVE fix the network stack requires a hardware
random number generator. This can currently be a modern CPU supporting
the RDRAND instruction or a virtio-rng device.
The latter is initialized during the BDS phase.
To ensure all depending (network) modules are also started, we need to
run the dispatcher once more after the device was initialized.
Without this, network boot is not available under certain hardware
configurations.
Fixes: 4c4ceb2ceb ("NetworkPkg: SECURITY PATCH CVE-2023-45237")
