RE: [PATCH v2] RANDOM: ATH9K RNG delivers zero bits of entropy

2016-08-07 Thread Pan, Miaoqing
The entropy was evaluated by crypto expert, the analysis report show the ADC with at least 10bits and up to 22 bits of min-entropy for a 32 bits value, we conservatively assume the min-entropy is 10 bits out of 32 bits, so that's why set entropy quality to 320/1024 = 10/32. Also we have expl

[PATCH v2] RANDOM: ATH9K RNG delivers zero bits of entropy

2016-08-07 Thread Stephan Mueller
The ATH9K driver implements an RNG which is completely bypassing the standard Linux HW generator logic. The RNG may or may not deliver entropy. Considering the conservative approach in treating entropy with respect to non-auditable sources, this patch changes the delivered entropy value to zero. T
