[PATCH] KVM: x86: only do L1TF workaround on affected processors

by Paolo Bonzini

KVM stores the gfn in MMIO SPTEs as a caching optimization. These are split in two parts, as in "[high 11111 low]", to thwart any attempt to use these bits in an L1TF attack. This works as long as there are 5 free bits between MAXPHYADDR and bit 50 (inclusive), leaving bit 51 free so that the MMIO access triggers a reserved-bit-set page fault. The bit positions however were computed wrongly for AMD processors that have encryption support. In this case, x86_phys_bits is reduced (for example from 48 to 43, to account for the C bit at position 47 and four bits used internally to store the SEV ASID and other stuff) while x86_cache_bits in would remain set to 48, and _all_ bits between the reduced MAXPHYADDR and bit 51 are set. Then low_phys_bits would also cover some of the bits that are set in the shadow_mmio_value, terribly confusing the gfn caching mechanism. To fix this, avoid splitting gfns as long as the processor does not have the L1TF bug (which includes all AMD processors). When there is no splitting, low_phys_bits can be set to the reduced MAXPHYADDR removing the overlap. This fixes "npt=0" operation on EPYC processors. Thanks to Maxim Levitsky for bisecting this bug.

While the helpers have been addressed through work in 6ae08ae3dea2 ("bpf: Add probe_read_{user, kernel} and probe_read_{user, kernel}_str helpers"), we need an option for bpf_trace_printk() as well to fix it. Similarly as with the helpers, force users to make an explicit choice by adding %pks and %pus specifier to bpf_trace_printk() which will then pick the corresponding strncpy_from_unsafe*() variant to perform the access under KERNEL_DS or USER_DS. The %pk* (kernel specifier) and %pu* (user specifier) can later also be extended for other objects aside strings that are probed and printed under tracing, and reused out of other facilities like bpf_seq_printf() or BTF based type printing. Existing behavior of %s for current users is still kept working for archs where it is not broken and therefore gated through CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE. For archs not having this property we fall-back to pick probing under KERNEL_DS as a sensible default.

[PATCH 06/12] gpu/drm: Ingenic: Fix incorrect assumption about plane->index

by Paul Cercueil

plane->index is NOT the index of the color plane in a YUV frame. Actually, a YUV frame is represented by a single drm_plane, even though it contains three Y, U, V planes.
