Subject: [PATCH 4.19 027/139] x86/speculation: Enable cross-hyperthread spectre v2 STIBP mitigation
Date: Tue,  4 Dec 2018 11:48:28 +0100
Message-ID: <20181204103651.094926231@linuxfoundation.org> (raw)
In-Reply-To: <20181204103649.950154335@linuxfoundation.org>

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jiri Kosina jkosina@suse.cz

commit 53c613fe6349994f023245519265999eed75957f upstream

STIBP is a feature provided by certain Intel ucodes / CPUs. This feature
(once enabled) prevents cross-hyperthread control of decisions made by
indirect branch predictors.

Enable this feature if

- the CPU is vulnerable to spectre v2
- the CPU supports SMT and has SMT siblings online
- spectre_v2 mitigation autoselection is enabled (default)

After some previous discussion, this leaves STIBP on all the time, as wrmsr
on crossing kernel boundary is a no-no. This could perhaps later be a bit
more optimized (like disabling it in NOHZ, experiment with disabling it in
idle, etc) if needed.

Note that the synchronization of the mask manipulation via newly added
spec_ctrl_mutex is currently not strictly needed, as the only updater is
already being serialized by cpu_add_remove_lock, but let's make this a
little bit more future-proof.
