Some of the devlink bits were tricky, but I think I got it right.

SPDX-License-Identifier: GPL-2.0 + +Cross-Thread Return Address Predictions +======================================= + +Certain AMD and Hygon processors are subject to a cross-thread return address +predictions vulnerability. When running in SMT mode and one sibling thread +transitions out of C0 state, the other sibling thread could use return target +predictions from the sibling thread that transitioned out of C0. + +The Spectre v2 mitigations protect the Linux kernel, as it fills the return +address prediction entries with safe targets when context switching to the idle +thread. However, KVM does allow a VMM to prevent exiting guest mode when +transitioning out of C0. This could result in a guest-controlled return target +being consumed by the sibling thread. + +Affected processors +------------------- + +The following CPUs are vulnerable: + + - AMD Family 17h processors + - Hygon Family 18h processors + +Related CVEs +------------ + +The following CVE entry is related to this issue: + + ============== ======================================= + CVE-2022-27672 Cross-Thread Return Address Predictions + ============== ======================================= + +Problem +------- + +Affected SMT-capable processors support 1T and 2T modes of execution when SMT +is enabled. In 2T mode, both threads in a core are executing code. For the +processor core to enter 1T mode, it is required that one of the threads +requests to transition out of the C0 state. This can be communicated with the +HLT instruction or with an MWAIT instruction that requests non-C0. +When the thread re-enters the C0 state, the processor transitions back +to 2T mode, assuming the other thread is also still in C0 state. + +In affected processors, the return address predictor (RAP) is partitioned +depending on the SMT mode. For instance, in 2T mode each thread uses a private +16-entry RAP, but in 1T mode, the active thread uses a 32-entry RAP. Upon +transition between 1T/2T mode, the RAP contents are not modified but the RAP +pointers (which control the next return target to use for predictions) may +change. This behavior may result in return targets from one SMT thread being +used by RET predictions in the sibling thread following a 1T/2T switch. In +particular, a RET instruction executed immediately after a transition to 1T may +use a return target from the thread that just became idle. In theory, this +could lead to information disclosure if the return targets used do not come +from trustworthy code. + +Attack scenarios +---------------- + +An attack can be mounted on affected processors by performing a series of CALL +instructions with targeted return locations and then transitioning out of C0 +state. + +Mitigation mechanism +-------------------- + +Before entering idle state, the kernel context switches to the idle thread. The +context switch fills the RAP entries (referred to as the RSB in Linux) with safe +targets by performing a sequence of CALL instructions. + +Prevent a guest VM from directly putting the processor into an idle state by +intercepting HLT and MWAIT instructions. + +Both mitigations are required to fully address this issue. + +Mitigation control on the kernel command line +--------------------------------------------- + +Use existing Spectre v2 mitigations that will fill the RSB on context switch. + +Mitigation control for KVM - module parameter +--------------------------------------------- + +By default, the KVM hypervisor mitigates this issue by intercepting guest +attempts to transition out of C0. A VMM can use the KVM_CAP_X86_DISABLE_EXITS +capability to override those interceptions, but since this is not common, the +mitigation that covers this path is not enabled by default. + +The mitigation for the KVM_CAP_X86_DISABLE_EXITS capability can be turned on +using the boolean module parameter mitigate_smt_rsb, e.g.: + kvm.mitigate_smt_rsb=1 diff --git a/Documentation/admin-guide/hw-vuln/index.rst b/Documentation/admin-guide/hw-vuln/index.rst index 4df436e7c417..e0614760a99e 100644 --- a/Documentation/admin-guide/hw-vuln/index.rst +++ b/Documentation/admin-guide/hw-vuln/index.rst @@ -18,3 +18,4 @@ are configurable at compile, boot or run time. core-scheduling.rst l1d_flush.rst processor_mmio_stale_data.rst + cross-thread-rsb.rst diff --git a/MAINTAINERS b/MAINTAINERS index ebbd05b7f007..c93d65a3d616 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -16135,7 +16135,7 @@ F: drivers/pci/controller/pci-v3-semi.c PCI ENDPOINT SUBSYSTEM M: Lorenzo Pieralisi <lpieralisi@kernel.org> -R: Krzysztof WilczyÅ„ski <kw@linux.com> +M: Krzysztof WilczyÅ„ski <kw@linux.com> R: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> R: Kishon Vijay Abraham I <kishon@kernel.org> L: linux-pci@vger.kernel.org @@ -16143,7 +16143,7 @@ S: Supported Q: https://patchwork.kernel.org/project/linux-pci/list/ B: https://bugzilla.kernel.org C: irc://irc.oftc.net/linux-pci -T: git git://git.kernel.org/pub/scm/linux/kernel/git/lpieralisi/pci.git +T: git git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git F: Documentation/PCI/endpoint/* F: Documentation/misc-devices/pci-endpoint-test.rst F: drivers/misc/pci_endpoint_test.c @@ -16178,7 +16178,7 @@ S: Supported Q: https://patchwork.kernel.org/project/linux-pci/list/ B: https://bugzilla.kernel.org C: irc://irc.oftc.net/linux-pci -T: git git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git +T: git git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git F: Documentation/driver-api/pci/p2pdma.rst F: drivers/pci/p2pdma.c F: include/linux/pci-p2pdma.h @@ -16200,14 +16200,14 @@ F: drivers/pci/controller/pci-xgene-msi.c PCI NATIVE HOST BRIDGE AND ENDPOINT DRIVERS M: Lorenzo Pieralisi <lpieralisi@kernel.org> +M: Krzysztof WilczyÅ„ski <kw@linux.com> R: Rob Herring <robh@kernel.org> -R: Krzysztof WilczyÅ„ski <kw@linux.com> L: linux-pci@vger.kernel.org S: Supported Q: https://patchwork.kernel.org/project/linux-pci/list/ B: https://bugzilla.kernel.org C: irc://irc.oftc.net/linux-pci -T: git git://git.kernel.org/pub/scm/linux/kernel/git/lpieralisi/pci.git +T: git git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git F: Documentation/devicetree/bindings/pci/ F: drivers/pci/controller/ F: drivers/pci/pci-bridge-emul.c @@ -16220,7 +16220,7 @@ S: Supported Q: https://patchwork.kernel.org/project/linux-pci/list/ B: https://bugzilla.kernel.org C: irc://irc.oftc.net/linux-pci -T: git git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git +T: git git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git F: Documentation/PCI/ F: Documentation/devicetree/bindings/pci/ F: arch/x86/kernel/early-quirks.c @@ -20120,6 +20120,7 @@ F: drivers/watchdog/sunplus_wdt.c SUPERH M: Yoshinori Sato <ysato@users.sourceforge.jp> M: Rich Felker <dalias@libc.org> +M: John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de> L: linux-sh@vger.kernel.org S: Maintained Q: http://patchwork.kernel.org/project/linux-sh/list/ @@ -20352,8 +20353,7 @@ S: Maintained F: drivers/platform/x86/system76_acpi.c SYSV FILESYSTEM -M: Christoph Hellwig <hch@infradead.org> -S: Maintained +S: Orphan F: Documentation/filesystems/sysv-fs.rst F: fs/sysv/ F: include/linux/sysv_fs.h @@ -21848,11 +21848,9 @@ W: http://en.wikipedia.org/wiki/Util-linux T: git git://git.kernel.org/pub/scm/utils/util-linux/util-linux.git UUID HELPERS -M: Christoph Hellwig <hch@lst.de> R: Andy Shevchenko <andriy.shevchenko@linux.intel.com> L: linux-kernel@vger.kernel.org S: Maintained -T: git git://git.infradead.org/users/hch/uuid.git F: include/linux/uuid.h F: include/uapi/linux/uuid.h F: lib/test_uuid.c @@ -2,7 +2,7 @@ VERSION = 6 PATCHLEVEL = 2 SUBLEVEL = 0 -EXTRAVERSION = -rc7 +EXTRAVERSION = -rc8 NAME = Hurr durr I'ma ninja sloth # *DOCUMENTATION* diff --git a/arch/arm/boot/dts/rk3288.dtsi b/arch/arm/boot/dts/rk3288.dtsi index 487b0e03d4b4..2ca76b69add7 100644 --- a/arch/arm/boot/dts/rk3288.dtsi +++ b/arch/arm/boot/dts/rk3288.dtsi @@ -1181,6 +1181,7 @@ clock-names = "dp", "pclk";
