Scanning all the filesystem groups impacts\nperformance.\n\nThis was demonstrated by using a freshly created, 70GB, 1k block\nfilesystem, with caches dropped write before the test via\n/proc/sys/vm/drop_caches, and with the filesystem mounted with\nnodelalloc and nodealloc,nomballoc.

If\nfirst_data_block is corrupted such that it is larger than ext4_blocks_count,\nfor example, then the intermediate blocks_count value may go negative,\nbut sign-extend to a very large value:\n\n blocks_count \u003d (ext4_blocks_count(es) -\n le32_to_cpu(es-\u003es_first_data_block) +\n EXT4_BLOCKS_PER_GROUP(sb) - 1);\n\nThis is then assigned to s_groups_count which is an unsigned long:\n\n sbi-\u003es_groups_count \u003d blocks_count;\n\nThis may result in a value of 0xFFFFFFFF which is then used to compute\ndb_count:\n\n db_count \u003d (sbi-\u003es_groups_count + EXT4_DESC_PER_BLOCK(sb) - 1) /\n EXT4_DESC_PER_BLOCK(sb);\n\nand in this case db_count will wind up as 0 because the addition overflows\n32 bits. This in turn causes the kmalloc for group_desc to be of 0 size:\n\n sbi-\u003es_group_desc \u003d kmalloc(db_count * sizeof (struct buffer_head *),\n GFP_KERNEL);\n\nand eventually in ext4_check_descriptors, dereferencing\nsbi-\u003es_group_desc[desc_block] will result in a NULL pointer dereference.\n\nThe simplest test seems to be to sanity check s_first_data_block,\nEXT4_BLOCKS_PER_GROUP, and ext4_blocks_count values to be sure\ntheir combination won\u0027t result in a bad intermediate value for\nblocks_count.
