The recent speculative execution CVEs address three potential attack vectors across a wide variety of processor architectures and platforms. Each platform requiring slightly different fixes. In many cases these fixes also require matching microcode updates provided by hardware vendors.
The security vulnerabilities described in these three CVEs may be found in modern microprocessors and operating systems on major hardware platforms including x86 (Intel and AMD chipsets), System Z, Power and ARM.
Red Hat has made updated kernels available to address these security vulnerabilities. These patches are enabled by default because Red Hat prioritizes out of the box security. Speculative execution is a performance optimization technique which these updates change (both kernel and microcode) and may result in workload-specific performance degradation.
Some customers who feel confident that their systems are well protected may wish to disable some or all of protection mechanisms. If the system administrator wishes elects to enable the protection mechanisms in the interest of security, this article provides a method to conduct performance characterizations with and without the fixes enabled.
With the upcoming Red Hat Enterprise Linux 7.7 release, it is planned that all new installations on all Intel processors up through and
including Skylake will default to use retpolines. However updates from versions from RHEL 7.6, and before, to RHEL-7.7, and later, will preserve the existing Spectre variant 2 mitigation methods that were in place before the upgrade.
A patched GCC compiler with Retpoline support is required for compiling the Retpoline patched kernel and third party modules. Any third party kernel module supplied prior to the update will require recompiling from source. SystemTap is one example that uses kernel modules to run code in kernel space, so it also needs the patched compiler. Please contact your software provider of the kernel module and request an update if the kernel module fails to work correctly.
For Red Hat Enterprise Linux kernels on x86, three debugfs tunables control the behaviour of the various patches in the updated kernel. These patches require updated microcode, which can be obtained from the hardware platform providers.
These debugfs tunables can be enabled or disabled on the kernel command line at boot or at runtime via debugfs controls. The tunables control Page Table Isolation (pti), Indirect Branch Restricted Speculation (ibrs), and retpolines (retp). Depending on the CPU type, Red Hat enables each of these features by default as needed to protect the architecture detected at boot.
Note this requires that the debugfs filesystem be mounted. In addition, the above "retp_enabled" alteration is only available at runtime for RHEL7 systems. This tunable is read-only for RHEL 6 systems. In RHEL 7 the debugfs is mounted by default. In RHEL 6 you can mount it manually with the command:
CVE-2017-5715 (variant #2/Spectre) is an indirect branching poisoning attack that can lead to data leakage. This attack allows for a virtualized guest to read memory from the host system. This issue is corrected with microcode, along with kernel and virtualization updates to both guest and host virtualization software. This vulnerability requires both updated microcode and kernel patches. Variant #2 behavior is controlled by the ibrs tunable which work in conjunction with the microcode, or the retp tunable. The ibpb tunable is still visible, but now read-only and is set by the kernel.
When ibrs_enabled is set to 3, only userland runs with indirect branch restricted speculation. This can be used in combination with retpoline (spectre_v2=retpoline,ibrs_user) to provide similar security to ibrs_always with less performance overhead.
Note: The ibpb tuning knob is now read-only and will be set by the kernel if either ibrs or retp is set. As with ibrs, ibpb needs updated microcode in order to work (and be set) correctly.
Ibpb controls the IBPB feature in the PRED_CMD model-specific register (MSR) if either IBPB_SUPPORT or SPEC_CTRL is present in cpuid (post microcode update). When ibpb_enabled is set to 1, an IBPB barrier that flushes the contents of the indirect branch prediction is run across user mode or guest mode context switches to prevent user and guest mode from attacking other applications or virtual machines on the same host. In order to protect virtual machines from other virtual machines, ibpb_enabled=1 is needed even if ibrs_enabled is set to 2. This feature addresses CVE-2017-5715, variant #2.
By default, the appropriate tunables that apply to an architecture will be enabled automatically at boot time, based upon the architecture detected. Per Intel's guidance, ( -software-guidance/api-app/sites/default/files/Retpoline-A-Branch-Target-Injection-Mitigation.pdf), both retpolines and IBRS are mitigations for Spectre variant 2. Retpolines will likely have a reduced performance impact.
Red Hat Enterprise Linux defaults on AMD CPUs:
Due to the differences in underlying hardware implementation, AMD X86 systems are not vulnerable to variant #3. The correct default values will be set on AMD hardware based on dynamic checks during the boot sequence.
The mitigation for variant 1 (ppa15) is always active if the feature is available in microcode. It cannot be switched on/off dynamically, you can only disable instruction patching completely via the kernel parameter noaltinstr.
For variant 2, mitigation is done via the bpb feature. As for ppa15, it is always active if the feature is available in microcode. It cannot be switched on/off dynamically either, but there is a kernel parameter nobp enabled by default which can be disabled with the nobp=off kernel parameter. (This patch uses a 'big hammer' approach, which has measurable performance impact).
IBM POWER Defaults
The mitigation for Spectre (Variants 1 and 2) are provided by the system firmware provided by the vendor. Currently there is no tunable available on Linux to disable these mitigations. The mitigation for variant 3 is provided by the Linux kernel, without depending on system firmware (although an optimized implementation is used in case system firmware provides support for it). It is enabled by default, and can be disabled on boot time, with the kernel command line parameters no_rfi_flush or nopti), or at run time, with either of the following tunables:
