Vinit Agnihotri d08c3b78b8 UBI: fix overflow bug ... I was experiencing overflows in multiplications for volume->used_bytes in vmt.c & vtbl.c, while creating & resizing large volumes. vol->used_bytes is long long however its 2 operands vol->used_ebs & vol->usable_leb_size are int. So their multiplication for larger values causes integer overflows. Typecasting them solves the problem. My machine & flash details: 64Bit dual-core AMD opteron, 1 GB RAM, linux 2.6.18.3. mtd size = 6GB, volume size= 5GB, peb_size = 4MB. heres patch which does the fix.
