Subject: [PATCH AUTOSEL 5.4 10/15] sparc: vdso: Disable UBSAN instrumentation
Date: Fri, 29 Mar 2024 08:34:33 -0400 [thread overview]
Message-ID: <20240329123445.3086536-10-sashal@kernel.org> (raw)
In-Reply-To: <20240329123445.3086536-1-sashal@kernel.org>
From: Kees Cook <keescook@chromium.org>
[ Upstream commit d4be85d068b4418c341f79b654399f7f0891069a ]
The UBSAN instrumentation cannot work in the vDSO since it is executing
in userspace, so disable it in the Makefile. Fixes the build failures
such as:
arch/sparc/vdso/vclock_gettime.c:217: undefined reference to `__ubsan_handle_shift_out_of_bounds'
Acked-by: Sam Ravnborg <sam@ravnborg.org>
