Description H. Peter Anvin 2012-09-16 23:25:45 UTC 
Description of problem:
Running Fedora 18 Alpha with updates on an Ivy Bridge system, rngd is not started by default.

Per FESCo decision it should be run by default:

https://fedoraproject.org/wiki/Features/rngd_default_on

Version-Release number of selected component (if applicable):
rng-tools-4-1.fc18.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Install rng-tools on an Ivy Bridge system or any other system with a hardware RNG
2. ps ax | grep rngd
   observe it is not running
3. service rngd start
   observe it can be started  
  
Actual results:
rngd run by default

Expected results:
rngd available, but not on by default

Additional info:
Comment 1 H. Peter Anvin 2012-12-07 21:04:03 UTC 
rngd is still disabled by default in Fedora 18 Beta.
Comment 2 Michal Schmidt 2012-12-10 13:16:26 UTC 
added rngd.service to the default presets:

Comment 3 Lennart Poettering 2013-01-11 13:35:02 UTC 
hpa, out of curiosity: why is this done in a userspace component rather than inside the kernel?
Comment 4 H. Peter Anvin 2013-01-11 23:41:42 UTC 
Long, sordid reasons -- short answer: some of the operations involved (FIPS test, whitening) are complex and considered too heavyweight to be done in kernel space.
