Subject: [PATCH master 5/7] sandbox: fix SANDBOX_UNWIND dependency to be KASAN only
Date: Mon, 14 Sep 2020 12:05:51 +0200	[thread overview]
Message-ID: <20200914100553.24808-5-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20200914100553.24808-1-a.fatoum@pengutronix.de>

gcc v9.3.0's libubsan does not export a __sanitizer_print_stack_trace
symbol. Play it safe and avoid possible linker errors by having the
optional SANDBOX_UNWIND depend only on CONFIG_KASAN.
