From 7d90f7603af6b59e7144cef6617a1e9dd42161bd Mon Sep 17 00:00:00 2001 From: Jes Sorensen <jsorensen@fb.com> Date: Mon, 18 May 2020 20:19:53 -0400 Subject: [PATCH 80/89] Include count for \0 character when using strncpy to implement strdup. Git-commit: 7d90f7603af6b59e7144cef6617a1e9dd42161bd Patch-mainline: mdadm-4.1+ References: jsc#SLE-13700 We have to include the \0 character in the length when copying a string with strncpy() for which length was found with strlen(). Otherwise the destination will not get null terminated - except that we explicitly zeroed it out earlier. This quiets down the compiler's warnings.
