Title:
No driver provided for X-Gene's hardware RNG
Status in “linux” package in Ubuntu:
Fix Released
Status in “linux” source package in Trusty:
Fix Committed
Status in “linux” source package in Utopic:
Fix Released
Bug description:
[Impact]
User has a system with a built-in random number generator that the OS cannot
use.
[Test Case]
Make sure rng-tools is uninstalled.
Reboot with this driver, verify that it is automatically loaded. Leave system
idle for this test.
In one terminal, run 'watch cat /proc/sys/kernel/random/entropy_avail', and
note that the minor fluctuation in available entropy over time. Install
rng-tools, and notice that entropy shoots up and grows at a faster rate than
previously.
[Regression Potential]
If this driver is buggy it could cause e.g. an oops or a panic that would not
otherwise have occurred.
