https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=262604 Bug ID: 262604 Summary: Feature request: reseed kernel RNG after VM snapshot/resume Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: emaste@freebsd.org This came as a report to secteam@, but should be tracked in the public bugzilla. > Specifically, we've run FreeBSD inside VMware workstation 9.0.0, captured a > full-memory snapshot (using the ‘snapshot' button in VMware), and resumed the > guest VM multiple times from the same snapshot (using the ‘revert’ button in > VMware). We’ve observed that /dev/random produces repeated outputs each time > the guest is resumed from the same snapshot. In the worst case, we’ve observed > repeated outputs for as long as 100 seconds after resumption.
