* Better fix for r314098Baptiste Daroussin2017-02-221-1/+2
| | | | | | | | | | | | | | | | | The actual issue was the fact that if - was used then some restriction were already set to stdin when we were applying caph_limit_stdio which was failing due to the fact the fd was the fd was already restricted to lower rights. Restricting stdio before actually opening the files prevent trying to raise the right and fixes the issue. And this allows to keep failing the program if restriction failed Approved by: allanjude Differential Revision: https://reviews.freebsd.org/D9723 Notes: svn path=/head/; revision=314099
