c269c9fb36 Use a consistent style and one much closer to the rest of /usr/src 2001-01-06 14:00:42 +00:00

14f55e3a6c Default the /dev/random loadable module to blocking-on-bootup,
but leave a commented-out macro to change this.

6458d733a9 As the blocking model has seems to be troublesome for many, disable
it for now with an option.

This option is already deprecated, and will be removed when the
entropy-harvesting code is fast enough to warrant it.

a8d2363750 After some complaints about the dir names, the random device is
now in dirs called sys/*/random/ instead of sys/*/randomdev/*.

Introduce blocking, but only at startup; the random device will
block until the first reseed happens to prevent clients from
using untrustworthy output.

Provide a read_random() call for the rest of the kernel so that
the entropy device does not need to be present. This means that
things like IPX no longer need to have "device random" hardcoded
into thir kernel config. The downside is that read_random() will
provide very poor output until the entropy device is loaded and
reseeded. It is recommended that developers do NOT use the
read_random() call; instead, they should use arc4random() which
internally uses read_random().

Clean up the mutex and locking code a bit; this makes it possible
to unload the module again.

bda6631159 Large upgrade to the entropy device; mainly inspired by feedback
from many folk.

o The reseed process is now a kthread. With SMPng, kthreads are
  pre-emptive, so the annoying jerkiness of the mouse is gone.

o The data structures are protected by mutexes now, not splfoo()/splx().

o The cryptographic routines are broken out into their own subroutines.
  this facilitates review, and possible replacement if that is ever
  found necessary.

3d0396c734 Add entropy gathering code. This will work whether the module is
compiled in or loaded.

a66f2ab5fa Build the entropy device (/dev/random) as a module. This may not
be a permanent rule, because this device may eventually be deemed
"effectively compulsory", and built by default directly into the
kernel. For the moment, however, this is useful for debugging and
development.
