Donenfeld --- > So the question is should we trade performance or correctness? Or do neither, and just hold your horses until we can sort this vDSO stuff = out in the kernel? That might take some time, but remember: arc4random() didn't even exist in glibc a few weeks ago. It was you all who rushed this in over= my objections. Don't now follow that bad decision making to its next bad step = of introducing intentional correctness issues. Instead just chill out for a li= ttle bit, don't take further actions, and let's see what is possible in the kern= el. Just stop spinning your wheels over this stuff for a while, okay? --=20 You are receiving this mail because: You are on the CC list for the bug.=
