Subject: [PATCH 09/27] selftests/landlock: Assert tracefs_extract_field() results that are used
Date: Thu, 8 Oct 2026 16:25:38 +0200 [thread overview]
Message-ID: <20261008142604.39107-11-gnoack3000@gmail.com> (raw)
In-Reply-To: <20261008142604.39107-2-gnoack3000@gmail.com>
Several trace tests check tracefs_extract_field() with EXPECT_EQ() and
then compare the extracted field. If the extraction fails, the field
buffer is left uninitialized and the following comparison reads it.
Use ASSERT_EQ() for these calls, as the other trace tests already do.
