Re: [libvirt] [PATCH 2/5] virt-aa-helper: Fix return value of add_file_path

Commit a8853344994a7c6aaca882a5e949ab5536821ab5 added this function and wrapped vah_add_file in it. vah_add_file may return -1, 0, 1. It returns 1 in case the call to valid_path detects a restricted file. The original code treated a return value != 0 as error. The refactored code treats a return value < 0 as error. This triggers segfault in virt-aa-helper and breaks virt-aa-helper-test for the restricted file tests. Make sure that add_file_path returns -1 on error.
