09:45:59 2024 +0800 # # powerpc/kasan: Fix addr error caused by page alignment # # In kasan_init_region, when k_start is not page aligned, at the begin of # for loop, k_cur = k_start & PAGE_MASK is less than k_start, and then # `va = block + k_cur - k_start` is less than block, the addr va is invalid, # because the memory address space from va to block is not alloced by # memblock_alloc, which will not be reserved by memblock_reserve later, it # will be used by other places. # # As a result, memory overwriting occurs. # # for example: # int __init __weak kasan_init_region(void start, size_t size) # { # [...] # / if say block(dcd97000) k_start(feef7400) k_end(feeff3fe) / # block = memblock_alloc(k_end - k_start, PAGE_SIZE); # [...] # for (k_cur = k_start & PAGE_MASK; k_cur < k_end; k_cur += PAGE_SIZE) { # / at the begin of for loop # * block(dcd97000) va(dcd96c00) k_cur(feef7000) k_start(feef7400) # * va(dcd96c00) is less than block(dcd97000), va is invalid # / # void va = block + k_cur - k_start; # [...] # } # [...] # } # # Therefore, page alignment is performed on k_start before # memblock_alloc() to ensure the validity of the VA address. # # Fixes: 663c0c9496a6
