Can an attacker observe that the address on the DRAM is read or written?Or can an attacker know the read after write pattern?
I tried your tool, but was not able to obtain the correct values. I've tried with different allocation sizes and even with different sets, althought I was sure to know which value to provide.
The README states that "the code contains hardcoded addresses and thresholds that are specific to [your] systems". Are there values I can tweak to get better results? If yes, which?
Currently the program quits always with Couldn't find set after 10 tries, giving up, sorry!
or (seldom) with a std::bad_array_new_length
exception. I didn't try to debug it and can't provide further information on it right now, but If you are interested to resolve this issue, I could provide additional information on my test system, RAM organization etc.
What should the expected number of sets be? The total number of sets of non-conflicting (at the row level) addresses?
For example, on a dual channel system, with 2 ranks/DIMM and DDR4 (16 banks), does that lead to 2 * 2 * 16 = 64 sets? Based on the default value of 8, I'm guessing that's not correct...
hey...just wondering how could my machine does not have a single bit flip when I'm running your demo drama + rowhammer. My machine is a 6th Core I7, with two 8G DDR4.
thanks
