This is a directory, with the following entries:

|
||||
* ``boot_id``: a UUID generated the first time this is retrieved, and
|
||||
unvarying after that;
|
||||
|
||||
* ``uuid``: a UUID generated every time this is retrieved (this can
|
||||
thus be used to generate UUIDs at will);
|
||||
|
||||
* ``entropy_avail``: the pool's entropy count, in bits;
|
||||
|
||||
* ``poolsize``: the entropy pool size, in bits;
|
||||
|
||||
* ``urandom_min_reseed_secs``: obsolete (used to determine the minimum
|
||||
number of seconds between urandom pool reseeding). This file is

writable for compatibility purposes, but writing to it has no effect
|
||||
on any RNG behavior;
|
||||
|
||||
* ``write_wakeup_threshold``: when the entropy count drops below this
|
||||
(as a number of bits), processes waiting to write to ``/dev/random``
|
||||
are woken up. This file is writable for compatibility purposes, but

writing to it has no effect on any RNG behavior.

|

Assume that CPU manufacturer (e.g., Intel or AMD for RDSEED or
|
||||
RDRAND, IBM for the S390 and Power PC architectures) is trustworthy
|
||||
for the purposes of initializing Linux's CRNG. Since this is not
|
||||
something that can be independently audited, this amounts to trusting
|
||||
that CPU manufacturer (perhaps with the insistence or mandate
|
||||
of a Nation State's intelligence or law enforcement agencies)
|
||||
has not installed a hidden back door to compromise the CPU's
|
||||
random number generation facilities. This can also be configured
|
||||
at boot with "random.trust_cpu=on/off".
|
||||
Initialize the RNG using random numbers supplied by the CPU's
|
||||
RNG instructions (e.g. RDRAND), if supported and available. These
|
||||
random numbers are never used directly, but are rather hashed into
|
||||
the main input pool, and this happens regardless of whether or not
|
||||
this option is enabled. Instead, this option controls whether the
|
||||
they are credited and hence can initialize the RNG. Additionally,
|
||||
other sources of randomness are always used, regardless of this
|
||||
setting. Enabling this implies trusting that the CPU can supply high
|
||||
quality and non-backdoored random numbers.
|
||||
|
||||
Say Y here unless you have reason to mistrust your CPU or believe
|
||||
its RNG facilities may be faulty. This may also be configured at
|

boot time with "random.trust_cpu=on/off".

help
|

Some bootloaders can provide entropy to increase the kernel's initial
|
||||
device randomness. Say Y here to assume the entropy provided by the
|
||||
booloader is trustworthy so it will be added to the kernel's entropy
|
||||
pool. Otherwise, say N here so it will be regarded as device input that
|
||||
only mixes the entropy pool.
|
||||
Initialize the RNG using a seed supplied by the bootloader or boot
|
||||
environment (e.g. EFI or a bootloader-generated device tree). This
|
||||
seed is not used directly, but is rather hashed into the main input
|

pool, and this happens regardless of whether or not this option is
