Hi, syzbot configs/cmdline args are stored here: https://github.com/google/syzkaller/tree/master/dashboard/config I've tried to update to the latest kernel, the diff is below. Few questions: 1. How are modules enabled now? We pass security=selinux of security=smack on command line. What do we need to pass now to enable several modules at the same time? 2. What exactly does SECURITY_SAFESETID do? syzkaller executor uses setuid/gid, and the config says "to only those approved by a system-wide whitelist". What/where is that whitelist? If we just enable it, but not whitelist will it break syzkaller? diff --git a/dashboard/config/upstream-kasan.config b/dashboard/config/upstream-kasan.config index 475d84a3..ed026cd8 100644 --- a/dashboard/config/upstream-kasan.config +++ b/dashboard/config/upstream-kasan.config @@ -1,6 +1,6 @@ #
