[PATCH v3 0/8] rerandomize RNG seeds on reboot and handle record&replay

Posted by Jason A. Donenfeld 1 year, 7 months ago

When the system reboots, the rng seed that QEMU passes should be
re-randomized, so that the new boot gets a new seed. This series wires
that up for FDT.

Then, since the record&replay subsystem makes use of reset as well, we
add a new reset cause for record&replay, so that we can avoid
re-randomizing in these cases.

Jason A. Donenfeld (8):
  reset: allow registering handlers that aren't called by snapshot
    loading
  x86: do not re-randomize RNG seed on snapshot load
  device-tree: add re-randomization helper function
  arm: re-randomize rng-seed on reboot
  riscv: re-randomize rng-seed on reboot
  openrisc: re-randomize rng-seed on reboot
  rx: re-randomize rng-seed on reboot
  mips: re-randomize rng-seed on reboot

Hey Peter,

Could you queue this up again like last time?

Thanks,
