Rob Gill	c181978d7c	fix(arm): Updated arm cortex status (#209) ... * Cortex A8 Vulnerable Arm Cortex A8 is vulnerable to variants 1 & 2 (https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability) Part number is 0xc08 (https://developer.arm.com/docs/ddi0344/b/system-control-coprocessor/system-control-coprocessorregisters/c0-main-id-register) False negative reported by @V10lator in #206 * ARM Cortex A12 Vulnerable to 1&2 https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability * A76 vulnerable to variant 4 All arch 8 cortex A57-A76 are vulnerable to variant 4. https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability * Whitelist variant4 nonvuln Arms * ARM Cortex Whitelist & Cumulative Blacklist Applies all information about vulnerabilities of ARM Cortex processors (from https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability). Whitelist & blacklist approach, using both vulnerable and non vulnerable status for each identified CPU, with vulnerabilities tracked cumulatively for multi CPU systems.	2018-06-16 12:14:39 +02:00
Rob Gill	5962d20ba7	fix(variant4): whitelist from common.c::cpu_no_spec_store_bypass (#202) ... * variant4 from common.c::cpu_no_spec_store_bypass Variant 4 - Add function to 'whitelist' the hand-full of CPUs unaffected by speculative store bypass. This would allow improved determination of variant 4 status ( #189 ) of immune CPUs while waiting for the 4.17/stable patches to be backported to distro kernels. Source of cpu list : https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/x86/kernel/cpu/common.c#n945) Modeled after is_cpu_specex_free() * amd families fix amd families are reported by parse_cpu_details() in decimal * remove duplicates Only list processors which speculate and are immune to variant 4. Avoids duplication with non-speculating CPUs listed in is_cpu_specex_free()	2018-05-27 15:14:29 +02:00

Rob Gill	7e4899bcb8	ibrs can't be enabled on no ibrs cpu (#195) ... * ibrs can't be enabled on no ibrs cpu If the cpu is identified, and does not support SPEC_CTRL or IBRS, then ibrs can't be enabled, even if supported by the kernel. Instead of reporting IBRS enabled and active UNKNOWN, report IBRS enabled and active NO.	2018-05-17 15:39:48 +02:00
