Message-Id: <1365543543-17522-1-git-send-email-david.a.cohen@intel.com> Date: Tue, 9 Apr 2013 14:39:03 -0700 From: David Cohen <david.a.cohen@...el.com> To: rusty@...tcorp.com.au, dhowells@...hat.com Cc: linux-kernel@...r.kernel.org, mark.gross@...el.com, David Cohen <david.a.cohen@...el.com> Subject: [PATCH v2] MODSIGN: do not send garbage to stderr when enabling modules signature openssl may send garbage to stderr when generating X.509 key pair for modules signature regardless there was an error or not. It makes more difficult to create scripts based on kernel error/warning messages. When compiling kernel with -jN (N > 1), all warning/error messages printed while openssl is generating key pair may get mixed dots and other symbols openssl sends to stderr. This patch makes sure openssl logs go to default stdout.
