From f230c11771875adc1f74bef013e8cea1fa1867bc Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Sun, 7 Jul 2024 17:54:49 +0100 Subject: [PATCH] utils: use strlcpy when appropriate For util functions called with a buffer and length parameter we should use strlcpy() instead of strncpy(), as those functions are called with sizeof(buffer) as parameter.
