Subject: [PATCH 5.4 088/151] ARM: 9019/1: kprobes: Avoid fortify_panic() when copying optprobe template
Date: Tue, 17 Nov 2020 14:05:18 +0100 [thread overview]
Message-ID: <20201117122125.696799502@linuxfoundation.org> (raw)
In-Reply-To: <20201117122121.381905960@linuxfoundation.org>
From: Andrew Jeffery <andrew@aj.id.au>
[ Upstream commit 9fa2e7af3d53a4b769136eccc32c02e128a4ee51 ]
Setting both CONFIG_KPROBES=y and CONFIG_FORTIFY_SOURCE=y on ARM leads
to a panic in memcpy() when injecting a kprobe despite the fixes found
in commit e46daee53bb5 ("ARM: 8806/1: kprobes: Fix false positive with
FORTIFY_SOURCE") and commit 0ac569bf6a79 ("ARM: 8834/1: Fix: kprobes:
optimized kprobes illegal instruction").
arch/arm/include/asm/kprobes.h effectively declares
the target type of the optprobe_template_entry assembly label as a u32
which leads memcpy()'s __builtin_object_size() call to determine that
the pointed-to object is of size four. However, the symbol is used as a handle
for the optimised probe assembly template that is at least 96 bytes in size.
The symbol's use despite its type blows up the memcpy() in ARM's
arch_prepare_optimized_kprobe() with a false-positive fortify_panic() when it
should instead copy the optimised probe template into place:
```
