From 4ad98ac46490d5f8441025930070eaf028cfd0f2 Mon Sep 17 00:00:00 2001 From: Tetsuo Handa Date: Tue, 7 May 2019 20:34:22 +0900 Subject: [PATCH] tomoyo: Don't emit WARNING: string while fuzzing testing. Commit cff0e6c3ec3e6230 ("tomoyo: Add a kernel config option for fuzzing testing.") enabled the learning mode, but syzkaller is detecting any "WARNING:" string as a crash. Thus, disable TOMOYO's quota warning if built for fuzzing testing.
