Subject: [PATCH AUTOSEL 6.13 19/34] objtool: Stop UNRET validation on UD2
Date: Mon, 14 Apr 2025 09:27:13 -0400 [thread overview]
Message-ID: <20250414132729.679254-19-sashal@kernel.org> (raw)
In-Reply-To: <20250414132729.679254-1-sashal@kernel.org>
From: Josh Poimboeuf <jpoimboe@kernel.org>
[ Upstream commit 9f9cc012c2cbac4833746a0182e06a8eec940d19 ]
In preparation for simplifying INSN_SYSCALL, make validate_unret()
terminate control flow on UD2 just like validate_branch() already does.
