Commit 7a8e71b ("mm/slab: use stride to access slabobj_ext") defined the type of slab->stride as unsigned short, because the author initially planned to store stride within the lower 16 bits of the page_type field, but later stored it in unused bits in the counters field instead. However, the idea of having only 2-byte stride turned out to be a serious mistake. On systems with 64k pages, order-1 pages are 128k, which is larger than USHRT_MAX. It triggers a debug warning because s->size is 128k while stride, truncated to 2 bytes, becomes zero: ------------[ cut here ]------------ Warning! stride (0) != s->size (131072) WARNING: mm/slub.c:2231 at alloc_slab_obj_exts_early.constprop.0+0x524/0x534, CPU#6: systemd-sysctl/307 Modules linked in: CPU: 6 UID: 0 PID: 307 Comm: systemd-sysctl Not tainted 7.0.0-rc1+ #6 PREEMPTLAZY Hardware name: IBM,9009-22A POWER9 (architected) 0x4e0202 0xf000005 of:IBM,FW950.E0 (VL950_179) hv:phyp pSeries NIP: c0000000008a9ac0 LR: c0000000008a9abc CTR: 0000000000000000 REGS: c0000000141f7390 TRAP: 0700 Not tainted (7.0.0-rc1+) MSR: 8000000000029033 <SF,EE,ME,IR,DR,RI,LE> CR: 28004400 XER: 00000005 CFAR: c000000000279318 IRQMASK: 0 GPR00: c0000000008a9abc c0000000141f7630 c00000000252a300 c00000001427b200 GPR04: 0000000000000004 0000000000000000 c000000000278fd0 0000000000000000 GPR08: fffffffffffe0000 0000000000000000 0000000000000000 0000000022004400 GPR12: c000000000f644b0 c000000017ff8f00 0000000000000000 0000000000000000 GPR16: 0000000000000000 c0000000141f7aa0 0000000000000000 c0000000141f7a88 GPR20: 0000000000000000 0000000000400cc0 ffffffffffffffff c00000001427b180 GPR24: 0000000000000004 00000000000c0cc0 c000000004e89a20 c00000005de90011 GPR28: 0000000000010010 c00000005df00000 c000000006017f80 c00c000000177a00 NIP [c0000000008a9ac0] alloc_slab_obj_exts_early.constprop.0+0x524/0x534 LR [c0000000008a9abc] alloc_slab_obj_exts_early.constprop.0+0x520/0x534 Call Trace: [c0000000141f7630] [c0000000008a9abc] alloc_slab_obj_exts_early.constprop.0+0x520/0x534 (unreliable) [c0000000141f76c0] [c0000000008aafbc] allocate_slab+0x154/0x94c [c0000000141f7760] [c0000000008b41c0] refill_objects+0x124/0x16c [c0000000141f77c0] [c0000000008b4be0] __pcs_replace_empty_main+0x2b0/0x444 [c0000000141f7810] [c0000000008b9600] __kvmalloc_node_noprof+0x840/0x914 [c0000000141f7900] [c000000000a3dd40] seq_read_iter+0x60c/0xb00 [c0000000141f7a10] [c000000000b36b24] proc_reg_read_iter+0x154/0x1fc [c0000000141f7a50] [c0000000009cee7c] vfs_read+0x39c/0x4e4 [c0000000141f7b30] [c0000000009d0214] ksys_read+0x9c/0x180 [c0000000141f7b90] [c00000000003a8d0] system_call_exception+0x1e0/0x4b0 [c0000000141f7e50] [c00000000000d05c] system_call_vectored_common+0x15c/0x2ec This leads to slab_obj_ext() returning the first slabobj_ext or all objects and confuses the reference counting of object cgroups [1] and memory (un)charging for memory cgroups [2]. Fortunately, the counters field has 32 unused bits instead of 16 on 64-bit CPUs, which is wide enough to hold any value of s->size. Change the type to unsigned int.
