From 66cedb3078ebe78174efd51673632eb3bfb9be61 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Thu, 23 Oct 2014 19:07:02 +0200 Subject: [PATCH] selinux: simplify and unify logging Normally we shouldn#t log from "library" functions, but SELinux is weird, hence upgrade security messages uniformly to LOG_ERR when in enforcing mode. --- src/shared/selinux-util.c | 18 +++++++++--------- 1 file changed, 9 insertions(+), 9 deletions(-) diff --git a/src/shared/selinux-util.c b/src/shared/selinux-util.c index c59ad31ed..76d3916ea 100644 --- a/src/shared/selinux-util.c +++ b/src/shared/selinux-util.c @@ -42,6 +42,8 @@ DEFINE_TRIVIAL_CLEANUP_FUNC(context_t, context_free); static int cached_use = -1; static struct selabel_handle *label_hnd = NULL; + +#define log_enforcing(...) log_full(security_getenforce() == 1 ?
