Subject: [PATCH 5.10 138/148] x86/kvm: fix FASTOP_SIZE when return thunks are enabled
Date: Sat, 23 Jul 2022 11:55:50 +0200 [thread overview]
Message-ID: <20220723095303.038128243@linuxfoundation.org> (raw)
In-Reply-To: <20220723095224.302504400@linuxfoundation.org>
From: Thadeu Lima de Souza Cascardo <cascardo@canonical.com>
commit 84e7051c0bc1f2a13101553959b3a9d9a8e24939 upstream.
The return thunk call makes the fastop functions larger, just like IBT
does. Consider a 16-byte FASTOP_SIZE when CONFIG_RETHUNK is enabled.
Otherwise, functions will be incorrectly aligned and when computing their
position for differently sized operators, they will executed in the middle
or end of a function, which may as well be an int3, leading to a crash
like:
