From 927dc33070563d6646c903daf919dde80d8878d4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Tue, 13 Jul 2021 10:05:20 +0200 Subject: [PATCH] advice.h: add missing __attribute__((format)) & fix usage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add the missing __attribute__((format)) checking to advise_if_enabled(). This revealed a trivial issue introduced in b3b18d16213 (advice: revamp advise API, 2020-03-02). We treated the argv[1] as a format string, but did not intend to do so. Let's use "%s" and pass argv[1] as an argument instead.
