Subject: [PATCH 4.14 113/118] x86/retpoline: Fill return stack buffer on vmexit
Date: Mon, 15 Jan 2018 13:35:40 +0100 [thread overview]
Message-ID: <20180115123422.065013360@linuxfoundation.org> (raw)
In-Reply-To: <20180115123415.325497625@linuxfoundation.org>
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Woodhouse <dwmw@amazon.co.uk>
commit 117cc7a908c83697b0b737d15ae1eb5943afe35b upstream.
In accordance with the Intel and AMD documentation, we need to overwrite
all entries in the RSB on exiting a guest, to prevent malicious branch
target predictions from affecting the host kernel. This is needed both
for retpoline and for IBRS.
[ak: numbers again for the RSB stuffing labels]
