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.
Version 4 prevents the new reset type from leaking over QAPI, documents
this alongside which version it was introduced, and adds mips and m68k
machine types to the queue.
Jason A. Donenfeld (11):
reset: allow registering handlers that aren't called by snapshot
loading
device-tree: add re-randomization helper function
x86: do not re-randomize RNG seed on snapshot load
arm: re-randomize rng-seed on reboot
riscv: re-randomize rng-seed on reboot
m68k/virt: do not re-randomize RNG seed on snapshot load
m68k/q800: do not re-randomize RNG seed on snapshot load
mips/boston: re-randomize rng-seed on reboot
mips/malta: pass RNG seed via env var and re-randomize on reboot
openrisc: re-randomize rng-seed on reboot
rx: re-randomize rng-seed on reboot
