-0700 # # Merge branch 'l1tf-final' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip # # Merge L1 Terminal Fault fixes from Thomas Gleixner: # "L1TF, aka L1 Terminal Fault, is yet another speculative hardware # engineering trainwreck. It's a hardware vulnerability which allows # unprivileged speculative access to data which is available in the # Level 1 Data Cache when the page table entry controlling the virtual # address, which is used for the access, has the Present bit cleared or # other reserved bits set. # # If an instruction accesses a virtual address for which the relevant # page table entry (PTE) has the Present bit cleared or other reserved # bits set, then speculative execution ignores the invalid PTE and loads # the referenced data if it is present in the Level 1 Data Cache, as if # the page referenced by the address bits in the PTE was still present # and accessible. # # While this is a purely speculative mechanism and the instruction will # raise a page fault when it is retired eventually, the pure act of # loading the data and making it available to other speculative # instructions opens up the opportunity for side channel attacks to # unprivileged malicious code, similar to the Meltdown attack. # # While Meltdown breaks the user space to kernel space protection, L1TF # allows to attack any physical memory address in the system and the # attack works across all protection domains. It allows an attack of SGX # and also works from inside virtual machines because the speculation # bypasses the extended page table (EPT) protection mechanism. # # The assoicated CVEs are: CVE-2018-3615, CVE-2018-3620, CVE-2018-3646 # # The mitigations provided by this pull request include: # # - Host side protection by inverting the upper address bits of a non # present page table entry so the entry points to uncacheable memory. # # - Hypervisor protection by flushing L1 Data Cache on VMENTER. # # - SMT (HyperThreading) control knobs, which allow to 'turn off' SMT # by offlining the sibling CPU threads. The knobs are available on # the kernel command line and at runtime via sysfs # # - Control knobs for the hypervisor mitigation, related to L1D flush # and SMT control. The knobs are available on the kernel command line # and at runtime via sysfs # # - Extensive documentation about L1TF including various degrees of # mitigations. # # Thanks to all people who have contributed to this in various ways - # patches, review, testing, backporting - and the fruitful, sometimes # heated, but at the end constructive discussions. # # There is work in progress to provide other forms of mitigations, which # might be less horrible performance wise for a particular kind of # workloads, but this is not yet ready for consumption due to their # complexity and limitations" #
