Specifically, concurrent "first" calls to rand(). There can be a moment when rand3_state is allocated but not completely set up with initstate_r(). Is this a known / documented issue? Should we try to do better?
P.S. I am seeing this issue from time to time when running ztest program (from ZFS). I guess that it uses rand() just because that's what OpenZFS did / does on illumos and Linux. P.P.S. Just realized that the problem can be relatively recent. https://svnweb.freebsd.org/base?view=revision&revision=357382 -- Andriy Gapon _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
