From 956bda08f6183078f13b70f6aa27d0529a3ec20a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Christian=20G=C3=B6ttsche?= Date: Tue, 7 Jun 2022 19:00:35 +0200 Subject: [PATCH] libselinux: restorecon: avoid printing NULL pointer MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The variable `curcon` is NULL in case the file has no current security context. Most C standard libraries handle it fine, avoid it nonetheless for standard conformance.
