From 50a2b3b61b897ada12c267538e9f65578c256880 Mon Sep 17 00:00:00 2001 From: Ulrich Hecht Date: Fri, 10 Jul 2009 16:43:26 +0200 Subject: [PATCH 32/33] linux-user: zero fstat buffer to initialize nsec fields The fstat implementation does not initialize the nanosecond fields in the stat buffer; this caused funny values to turn up there, preventing, for instance, cp -p from preserving timestamps because utimensat rejected the out-of-bounds nanosecond values. Resetting the entire structure to zero fixes that.
