Description cshao 2014-11-07 10:02:14 UTC 
Description of problem:
RHEV-H always persist the config info of "Strong Random Number Generator" after disable AES-NI options.

Version-Release number of selected component (if applicable):
rhev-hypervisor6-6.6-20141106.1
ovirt-node-3.0.1-19.el6.22.noarch

How reproducible:
100%

Steps to Reproduce:
1. Install RHEV-H
2. Enter Security menu, enable AES-NI and input Bytes Used(e.g. 123)
3. Save and check /etc/profile
4. Disable AES-NI
5. Save and check /etc/profile again.

Actual results:
RHEV-H always persist the config info of "Strong Random Number Generator" after disable AES-NI options.
1. step 3: export SSH_USE_STRONG_RNG=123
2. step 5: export OPENSSL_DISABLE_AES_NI=1
export SSH_USE_STRONG_RNG=123

Expected results:
RHEV-H should remove the config info of "Strong Random Number Generator" after disable AES-NI options.

Additional info:

Test version:
rhev-hypervisor7-7.2-20151112.1
ovirt-node-3.6.0-0.20.20151103git3d3779a.el7ev.noarch

Test steps:
1. Install RHEV-H
2. Enter Security menu, enable AES-NI and input Bytes Used(e.g. 123)
3. Save and check /etc/profile
4. Disable AES-NI
5. Save and check /etc/profile again.


Test result:
RHEV-H can remove the config info of "Strong Random Number Generator" after disable AES-NI options.

#grep "export" /etc/profile
    export HISTCONTROL=ignoreboth
    export HISTCONTROL=ignoredups
export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL
export OPENSSL_DISABLE_AES_NI=1

So the bug is fixed, change bug status to VERIFIED.
