Cost of vDSO at random addressCost of vDSO at random addressPosted Jun 10, 2011 18:20 UTC (Fri) by jreiser (subscriber, #11027)Parent article: On vsyscalls and the vDSO On i386, randomizing the address of the vDSO slows down the loading of prelinked shared libraries. Even /bin/cat, which uses just /lib/libc.so, suffers on 7% of invocations. Large GUI executables with many shared libraries suffer 60% of the time or more. https://bugzilla.redhat.com/show_bug.cgi?id=162797#c4

But that's marked FIXED, yet the vDSO's address is still randomized. What was done to fix it, and can we do something similar again?
