[patch 14/15] mm: fix the deadlock in finish_fault()

[patch 09/15] memblock: make for_each_mem_range() traverse MEMBLOCK_HOTPLUG regions

by Andrew Morton

From: Mike Rapoport <rppt(a)linux.ibm.com> Subject: memblock: make for_each_mem_range() traverse MEMBLOCK_HOTPLUG regions Commit b10d6bca8720 ("arch, drivers: replace for_each_membock() with for_each_mem_range()") didn't take into account that when there is movable_node parameter in the kernel command line, for_each_mem_range() would skip ranges marked with MEMBLOCK_HOTPLUG. The page table setup code in POWER uses for_each_mem_range() to create the linear mapping of the physical memory and since the regions marked as MEMORY_HOTPLUG are skipped, they never make it to the linear map. A later access to the memory in those ranges will fail: [ 2.271743] BUG: Unable to handle kernel data access on write at 0xc000000400000000 [ 2.271984] Faulting instruction address: 0xc00000000008a3c0 [ 2.272568] Oops: Kernel access of bad area, sig: 11 [#1] [ 2.272683] LE PAGE_SIZE=64K MMU=Radix SMP NR_CPUS=2048 NUMA pSeries [ 2.273063] Modules linked in: [ 2.273435] CPU: 0 PID: 53 Comm: kworker/u2:0 Not tainted 5.13.0 #7 [ 2.273832] NIP: c00000000008a3c0 LR: c0000000003c1ed8 CTR: 0000000000000040 [ 2.273918] REGS: c000000008a57770 TRAP: 0300 Not tainted (5.13.0) [ 2.274036] MSR: 8000000002009033 <SF,VEC,EE,ME,IR,DR,RI,LE> CR: 84222202 XER: 20040000 [ 2.274454] CFAR: c0000000003c1ed4 DAR: c000000400000000 DSISR: 42000000 IRQMASK: 0 [ 2.274454] GPR00: c0000000003c1ed8 c000000008a57a10 c0000000019da700 c000000400000000 [ 2.274454] GPR04: 0000000000000280 0000000000000180 0000000000000400 0000000000000200 [ 2.274454] GPR08: 0000000000000100 0000000000000080 0000000000000040 0000000000000300 [ 2.274454] GPR12: 0000000000000380 c000000001bc0000 c0000000001660c8 c000000006337e00 [ 2.274454] GPR16: 0000000000000000 0000000000000000 0000000000000000 0000000000000000 [ 2.274454] GPR20: 0000000040000000 0000000020000000 c000000001a81990 c000000008c30000 [ 2.274454] GPR24: c000000008c20000 c000000001a81998 000fffffffff0000 c000000001a819a0 [ 2.274454] GPR28: c000000001a81908 c00c000001000000 c000000008c40000 c000000008a64680 [ 2.275520] NIP [c00000000008a3c0] clear_user_page+0x50/0x80 [ 2.276333] LR [c0000000003c1ed8] __handle_mm_fault+0xc88/0x1910 [ 2.276688] Call Trace: [ 2.276839] [c000000008a57a10] [c0000000003c1e94] __handle_mm_fault+0xc44/0x1910 (unreliable) [ 2.277142] [c000000008a57af0] [c0000000003c2c90] handle_mm_fault+0x130/0x2a0 [ 2.277331] [c000000008a57b40] [c0000000003b5f08] __get_user_pages+0x248/0x610 [ 2.277541] [c000000008a57c40] [c0000000003b848c] __get_user_pages_remote+0x12c/0x3e0 [ 2.277768] [c000000008a57cd0] [c000000000473f24] get_arg_page+0x54/0xf0 [ 2.277959] [c000000008a57d10] [c000000000474a7c] copy_string_kernel+0x11c/0x210 [ 2.278159] [c000000008a57d80] [c00000000047663c] kernel_execve+0x16c/0x220 [ 2.278361] [c000000008a57dd0] [c000000000166270] call_usermodehelper_exec_async+0x1b0/0x2f0 [ 2.278543] [c000000008a57e10] [c00000000000d5ec] ret_from_kernel_thread+0x5c/0x70 [ 2.278870] Instruction dump: [ 2.279214] 79280fa4 79271764 79261f24 794ae8e2 7ca94214 7d683a14 7c893a14 7d893050 [ 2.279416] 7d4903a6 60000000 60000000 60000000 <7c001fec> 7c091fec 7c081fec 7c051fec [ 2.280193] ---[ end trace 490b8c67e6075e09 ]--- Making for_each_mem_range() include MEMBLOCK_HOTPLUG regions in the traversal fixes this issue.

It could only be enabed explicitly by init_mem_debugging_and_hardening(). But after the 51cba1eb static branch could already be enabled by default. There was no code to ever disable it. That caused page_poison=1 / init_on_free=1 conflict. This change extends init_mem_debugging_and_hardening() to also disable static branch disabling.

[patch 02/15] selftest: use mmap instead of posix_memalign to allocate memory

by Andrew Morton

From: Peter Collingbourne <pcc(a)google.com> Subject: selftest: use mmap instead of posix_memalign to allocate memory This test passes pointers obtained from anon_allocate_area to the userfaultfd and mremap APIs. This causes a problem if the system allocator returns tagged pointers because with the tagged address ABI the kernel rejects tagged addresses passed to these APIs, which would end up causing the test to fail. To make this test compatible with such system allocators, stop using the system allocator to allocate memory in anon_allocate_area, and instead just use mmap.

[patch 01/15] userfaultfd: do not untag user pointers

by Andrew Morton

From: Peter Collingbourne <pcc(a)google.com> Subject: userfaultfd: do not untag user pointers Patch series "userfaultfd: do not untag user pointers", v5. If a user program uses userfaultfd on ranges of heap memory, it may end up passing a tagged pointer to the kernel in the range.start field of the UFFDIO_REGISTER ioctl. This can happen when using an MTE-capable allocator, or on Android if using the Tagged Pointers feature for MTE readiness [1]. When a fault subsequently occurs, the tag is stripped from the fault address returned to the application in the fault.address field of struct uffd_msg. However, from the application's perspective, the tagged address *is* the memory address, so if the application is unaware of memory tags, it may get confused by receiving an address that is, from its point of view, outside of the bounds of the allocation. We observed this behavior in the kselftest for userfaultfd [2] but other applications could have the same problem. Address this by not untagging pointers passed to the userfaultfd ioctls. Instead, let the system call fail. Also change the kselftest to use mmap so that it doesn't encounter this problem. [1] https://source.android.com/devices/tech/debug/tagged-pointers [2] tools/testing/selftests/vm/userfaultfd.c This patch (of 2): If a user program uses userfaultfd on ranges of heap memory, it may end up passing a tagged pointer to the kernel in the range.start field of the UFFDIO_REGISTER ioctl. This can happen when using an MTE-capable allocator, or on Android if using the Tagged Pointers feature for MTE readiness [1]. When a fault subsequently occurs, the tag is stripped from the fault address returned to the application in the fault.address field of struct uffd_msg. However, from the application's perspective, the tagged address *is* the memory address, so if the application is unaware of memory tags, it may get confused by receiving an address that is, from its point of view, outside of the bounds of the allocation. We observed this behavior in the kselftest for userfaultfd [2] but other applications could have the same problem. Address this by not untagging pointers passed to the userfaultfd ioctls. Instead, let the system call fail. This will provide an early indication of problems with tag-unaware userspace code instead of letting the code get confused later, and is consistent with how we decided to handle brk/mmap/mremap in commit dcde237319e6 ("mm: Avoid creating virtual address aliases in brk()/mmap()/mremap()"), as well as being consistent with the existing tagged address ABI documentation relating to how ioctl arguments are handled. The code change is a revert of commit 7d0325749a6c ("userfaultfd: untag user pointers") plus some fixups to some additional calls to validate_range that have appeared since then.
