kernel: random32: seeding improvement [rhel-5.3]
Last modified: 2015-05-04 21:15:24 EDT
+++ This bug was initially created as a clone of Bug #458016 +++
Description of problem:
Stephen Hemminger wrote a patch to improve random32() seeding.
The rationale is:
* use u32 consistently
* no need to do LCG on values from (better) get_random_bytes
* use more data from get_random_bytes for secondary seeding
* don't reduce state space on srandom32()
* enforce state variable initialization restrictions
