| 4e6fffb | Alexander Potapenko | 09 January 2019, 17:39:16 UTC | kmsan: reimplement metadata_is_contiguous() and memcpy/memmove impl Make sure metadata_is_contiguous() really checks for metadata pages being contiguous. Rewrite kmsan_memcpy_memmove_metadata() assuming the metadata is always contiguous. | 10 January 2019, 12:24:31 UTC |
| 298053f | Alexander Potapenko | 09 January 2019, 17:33:39 UTC | block: kmsan: don't merge physical pages in scatterlists We're trying to move away from non-consequent metadata, and merged physical pages break the assumption that memory accesses may only touch consequent metadata ranges. | 10 January 2019, 12:24:31 UTC |
| 32736fb | Alexander Potapenko | 07 January 2019, 09:49:38 UTC | kmsan: fix a minor nit, NFC kmsan_get_metadata_or_null() was incorrectly called for origin instead of shadow. Fortunately we didn't use the result except for checking it for being NULL (which doesn't differ for shadow and origin) | 10 January 2019, 12:24:31 UTC |

| 1cbeb92 | Alexander Potapenko | 04 January 2019, 12:59:43 UTC | kmsan: improve init Split kmsan_initialize_shadow() into two parts: - kmsan_initialize_shadow() that's called from mm_init() and allocates shadow for memblock regions and kernel .data using the memblock allocator itself; - kmsan_initialize() that just sets up the init task and turns KMSAN on. | 10 January 2019, 12:24:31 UTC |

| 170abe1 | Alexander Potapenko | 24 December 2018, 10:56:27 UTC | kmsan: use per-cpu variable for runtime reentrancy counter Storing in_runtime in task_struct may lead to errors when accessing it from interrupts or scheduler code. Because interrupts are disabled between ENTER_RUNTIME/LEAVE_RUNTIME, keeping one counter per CPU should be enough. | 10 January 2019, 12:24:30 UTC |
