[PATCH v8 0/3] add support for rng-seed

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Introducing a chosen node, rng-seed, which is an entropy that can be
passed to kernel called very early to increase initial device
randomness. This can be used for adding sufficient initial entropy
for stack canary. Especially architectures that lack per-stack canary.

Hsin-Yi Wang (3):
  arm64: map FDT as RW for early_init_dt_scan()
  fdt: add support for rng-seed
  arm64: kexec_file: add rng-seed support
