The problem is that nested macros declare variables with the same name, which results in constructs like: __pu_val = (signo); do { __typeof__(*((&infop->si_signo))) __pu_val; __pu_val = __pu_val; } while (0) , leading to false positives. | 15 May 2019, 14:47:24 UTC |

| 2011a03 | Alexander Potapenko | 13 March 2019, 14:51:21 UTC | kmsan: another attempt to fix vmalloc Turned out that metadata_is_contiguous() never checked vmalloc()-ed memory ranges. Moreover, kmsan_get_metadata_or_null() and kmsan_get_shadow_origin_ptr() used to return pointers to physical pages for such memory ranges, which resulted in shadow and origin being non-contiguous. This led to corrupted metadata in certain cases. The new implementation makes vmalloc area 4 times smaller, so it's now possible to keep shadow and origin pages in the two following quarters of the vmalloc area. The shadow and origin addresses are now calculated by simply adding VMALLOC_SHADOW_OFFSET or VMALLOC_ORIGIN_OFFSET to a vmalloc address. We've implemented vmap() and ioremap() support accordingly, but this patch doesn't enable them, so the kernel may be broken here. | 15 May 2019, 14:47:24 UTC |
