I think Ubuntu 14.04's kernel is a bit old... 1291198 1 mcatanzaro 2017-03-25 07:55:39 -0700 Kernel is not the limiting factor here, but glibc, which took a very long time to add support for getrandom(). Unless you want to use getrandom() via syscall() directly. 1291202 2 ysuzuki 2017-03-25 08:04:30 -0700 (In reply to Michael Catanzaro from comment #1) > Kernel is not the limiting factor here, but glibc, which took a very long > time to add support for getrandom().

If so, syscall(SYS_getrandom, buf, length, 0) should work :) 1292004 3 ysuzuki 2017-03-28 12:28:23 -0700 OK, so, I'll do this in RandomDevice patch. *** This bug has been marked as a duplicate of bug 170095 *** 1292047 4 ysuzuki 2017-03-28 13:20:33 -0700 Buildbot seems not supporting SYS_getrandom.
