Subject: [PATCH v7 04/11] scs: disable when function graph tracing is enabled
Date: Tue, 28 Jan 2020 10:49:27 -0800
Message-ID: <20200128184934.77625-5-samitolvanen@google.com> (raw)
In-Reply-To: <20200128184934.77625-1-samitolvanen@google.com>

The graph tracer hooks returns by modifying frame records on the
(regular) stack, but with SCS the return address is taken from the
shadow stack, and the value in the frame record has no effect. As we
don't currently have a mechanism to determine the corresponding slot
on the shadow stack (and to pass this through the ftrace
infrastructure), for now let's disable SCS when the graph tracer is
enabled.
