FROMGIT: mm: lock vma explicitly before doing vm_flags_reset and vm_flags_reset_once
Implicit vma locking inside vm_flags_reset() and vm_flags_reset_once() is not obvious and makes it hard to understand where vma locking is happening. Also in some cases (like in dup_userfaultfd()) vma should be locked earlier than vma_flags modification. To make locking more visible, change these functions to assert that the vma write lock is taken and explicitly lock the vma beforehand. Fix userfaultfd functions which should lock the vma earlier.

mm/memory.c: fix race when faulting a device private page
Patch series "Fix several device private page reference counting issues", v2 This series aims to fix a number of page reference counting issues in drivers dealing with device private ZONE_DEVICE pages. These result in use-after-free type bugs, either from accessing a struct page which no longer exists because it has been removed or accessing fields within the struct page which are no longer valid because the page has been freed. During normal usage it is unlikely these will cause any problems. However without these fixes it is possible to crash the kernel from userspace. These crashes can be triggered either by unloading the kernel module or unbinding the device from the driver prior to a userspace task exiting. In modules such as Nouveau it is also possible to trigger some of these issues by explicitly closing the device file-descriptor prior to the task exiting and then accessing device private memory. This involves some minor changes to both PowerPC and AMD GPU code. Unfortunately I lack hardware to test either of those so any help there would be appreciated. The changes mimic what is done in for both Nouveau and hmm-tests though so I doubt they will cause problems. This patch (of 8): When the CPU tries to access a device private page the migrate_to_ram() callback associated with the pgmap for the page is called. However no reference is taken on the faulting page. Therefore a concurrent migration of the device private page can free the page and possibly the underlying pgmap. This results in a race which can crash the kernel due to the migrate_to_ram() function pointer becoming invalid. It also means drivers can't reliably read the zone_device_data field because the page may have been freed with memunmap_pages(). Close the race by getting a reference on the page while holding the ptl to ensure it has not been freed. Unfortunately the elevated reference count will cause the migration required to handle the fault to fail. To avoid this failure pass the faulting page into the migrate_vma functions so that if an elevated reference count is found it can be checked to see if it's expected or not.

Update the guest state and timing entry/exit accounting to use the new API, which was introduced following issues found[1]. KVM HV does possibly call instrumented code inside the guest context, and it does call srcu inside the guest context which is fragile at best. Switch to the new API, moving the guest context inside the srcu_read_lock/unlock region.

kvmhv_run_single_vcpu() disables PMIs as well as Linux irqs,
however the tick time accounting code enables and disables irqs and
not PMIs within this region. By chance this might not actually cause

KVM: PPC: Book3S HV P9: Clear vcpu cpu fields before enabling host irqs
On guest entry, vcpu->cpu and vcpu->arch.thread_cpu are set after disabling host irqs. On guest exit there is a window whre tick time accounting briefly enables irqs before these fields are cleared. Move them up to ensure they are cleared before host irqs are run. This is possibly not a problem, but is more symmetric and makes the fields less surprising.

KVM: PPC: Book3S HV: Fix decrementer migration
We used to have a workaround[1] for a hang during migration that was
made ineffective when we converted the decrementer expiry to be
relative to guest timebase.
The point of the workaround was that in the absence of an explicit
decrementer expiry value provided by userspace during migration, KVM
needs to initialize dec_expires to a value that will result in an
expired decrementer after subtracting the current guest timebase. That
stops the vcpu from hanging after migration due to a decrementer
that's too large.
If the dec_expires is now relative to guest timebase, its
initialization needs to be guest timebase-relative as well, otherwise
we end up with a decrementer expiry that is still larger than the
guest timebase.

KVM: Rename mmu_notifier_* to mmu_invalidate_*
The motivation of this renaming is to make these variables and related helper functions less mmu_notifier bound and can also be used for non mmu_notifier based page invalidation. mmu_invalidate_* was chosen to better describe the purpose of 'invalidating' a page that those variables are used for. - mmu_notifier_seq/range_start/range_end are renamed to mmu_invalidate_seq/range_start/range_end. - mmu_notifier_retry{_hva} helper functions are renamed to mmu_invalidate_retry{_hva}. - mmu_notifier_count is renamed to mmu_invalidate_in_progress to avoid confusion with mn_active_invalidate_count. - While here, also update kvm_inc/dec_notifier_count() to kvm_mmu_invalidate_begin/end() to match the change for mmu_notifier_count.

powerpc/powernv/kvm: Use darn for H_RANDOM on Power9
The existing logic in KVM to support guests calling H_RANDOM only works
on Power8, because it looks for an RNG in the device tree, but on Power9
we just use darn.
In addition the existing code needs to work in real mode, so we have the
special cased powernv_get_random_real_mode() to deal with that.
Instead just have KVM call ppc_md.get_random_seed(), and do the real
mode check inside of there, that way we use whatever RNG is available,
including darn on Power9.

random: handle archrandom with multiple longs
The archrandom interface was originally designed for x86, which supplies RDRAND/RDSEED for receiving random words into registers, resulting in one function to generate an int and another to generate a long. However, other architectures don't follow this. On arm64, the SMCCC TRNG interface can return between one and three longs. On s390, the CPACF TRNG interface can return arbitrary amounts, with four longs having the same cost as one. On UML, the os_getrandom() interface can return arbitrary amounts. So change the api signature to take a "max_longs" parameter designating the maximum number of longs requested, and then return the number of longs generated. Since callers need to check this return value and loop anyway, each arch implementation does not bother implementing its own loop to try again to fill the maximum number of longs. Additionally, all existing callers pass in a constant max_longs parameter. Taken together, these two things mean that the codegen doesn't really change much for one-word-at-a-time platforms, while performance is greatly improved on platforms such as s390.

KVM: PPC: Do not warn when userspace asked for too big TCE table
KVM manages emulated TCE tables for guest LIOBNs by a two level table which maps up to 128TiB with 16MB IOMMU pages (enabled in QEMU by default) and MAX_ORDER=11 (the kernel's default). Note that the last level of the table is allocated when actual TCE is updated. However these tables are created via ioctl() on kvmfd and the userspace can trigger WARN_ON_ONCE_GFP(order >= MAX_ORDER, gfp) in mm/page_alloc.c and flood dmesg. This adds __GFP_NOWARN.

KVM: PPC: Book3S HV: Provide more detailed timings for P9 entry path
Alter the data collection points for the debug timing code in the P9 path to be more in line with what the code does. The points where we accumulate time are now the following: vcpu_entry: From vcpu_run_hv entry until the start of the inner loop; guest_entry: From the start of the inner loop until the guest entry in asm; in_guest: From the guest entry in asm until the return to KVM C code; guest_exit: From the return into KVM C code until the corresponding hypercall/page fault handling or re-entry into the guest; hypercall: Time spent handling hcalls in the kernel (hcalls can go to QEMU, not accounted here); page_fault: Time spent handling page faults; vcpu_exit: vcpu_run_hv exit (almost no code here currently). Like before, these are exposed in debugfs in a file called "timings". There are four values: - number of occurrences of the accumulation point; - total time the vcpu spent in the phase in ns; - shortest time the vcpu spent in the phase in ns; - longest time the vcpu spent in the phase in ns; === Before: rm_entry: 53132 16793518 256 4060 rm_intr: 53132 2125914 22 340 rm_exit: 53132 24108344 374 2180 guest: 53132 40980507996 404 9997650 cede: 0 0 0 0 After: vcpu_entry: 34637 7716108 178 4416 guest_entry: 52414 49365608 324 747542 in_guest: 52411 40828715840 258 9997480 guest_exit: 52410 19681717182 826 102496674 vcpu_exit: 34636 1744462 38 182 hypercall: 45712 22878288 38 1307962 page_fault: 992 111104034 568 168688 With just one instruction (hcall): vcpu_entry: 1 942 942 942 guest_entry: 1 4044 4044 4044 in_guest: 1 1540 1540 1540 guest_exit: 1 3542 3542 3542 vcpu_exit: 1 80 80 80 hypercall: 0 0 0 0 page_fault: 0 0 0 0 === Signed-off-by: Fabiano Rosas <farosas@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/20220525130554.2614394-6-farosas@linux.ibm.com |

KVM: PPC: Book3S HV: Decouple the debug timing from the P8 entry path
We are currently doing the timing for debug purposes of the P9 entry path using the accumulators and terminology defined by the old entry path for P8 machines. Not only the "real-mode" and "napping" mentions are out of place for the P9 Radix entry path but also we cannot change them because the timing code is coupled to the structures defined in struct kvm_vcpu_arch. Add a new CONFIG_KVM_BOOK3S_HV_P9_TIMING to enable the timing code for the P9 entry path. For now, just add the new CONFIG and duplicate the structures. A subsequent patch will add the P9 changes.

KVM: PPC: Book3S HV: Fix "rm_exit" entry in debugfs timings
At debugfs/kvm/<pid>/vcpu0/timings we show how long each part of the code takes to run: $ cat /sys/kernel/debug/kvm/*-*/vcpu0/timings rm_entry: 123785 49398892 118 4898 rm_intr: 123780 6075890 22 390 rm_exit: 0 0 0 0 <-- NOK guest: 123780 46732919988 402 9997638 cede: 0 0 0 0 <-- OK, no cede napping in P9 The "rm_exit" is always showing zero because it is the last one and end_timing does not increment the counter of the previous entry. We can fix it by calling accumulate_time again instead of end_timing. That way the counter gets incremented. The rest of the arithmetic can be ignored because there are no timing points after this and the accumulators are reset before the next round.

powerpc: Book3S 64-bit outline-only KASAN support
Implement a limited form of KASAN for Book3S 64-bit machines running under the Radix MMU, supporting only outline mode. - Enable the compiler instrumentation to check addresses and maintain the shadow region. (This is the guts of KASAN which we can easily reuse.) - Require kasan-vmalloc support to handle modules and anything else in vmalloc space. - KASAN needs to be able to validate all pointer accesses, but we can't instrument all kernel addresses - only linear map and vmalloc. On boot, set up a single page of read-only shadow that marks all iomap and vmemmap accesses as valid. - Document KASAN in powerpc docs. Background ---------- KASAN support on Book3S is a bit tricky to get right: - It would be good to support inline instrumentation so as to be able to catch stack issues that cannot be caught with outline mode. - Inline instrumentation requires a fixed offset. - Book3S runs code with translations off ("real mode") during boot, including a lot of generic device-tree parsing code which is used to determine MMU features. [ppc64 mm note: The kernel installs a linear mapping at effective address c000...-c008.... This is a one-to-one mapping with physical memory from 0000... onward. Because of how memory accesses work on powerpc 64-bit Book3S, a kernel pointer in the linear map accesses the same memory both with translations on (accessing as an 'effective address'), and with translations off (accessing as a 'real address'). This works in both guests and the hypervisor. For more details, see s5.7 of Book III of version 3 of the ISA, in particular the Storage Control Overview, s5.7.3, and s5.7.5 - noting that this KASAN implementation currently only supports Radix.] - Some code - most notably a lot of KVM code - also runs with translations off after boot. - Therefore any offset has to point to memory that is valid with translations on or off. One approach is just to give up on inline instrumentation. This way boot-time checks can be delayed until after the MMU is set is up, and we can just not instrument any code that runs with translations off after booting. Take this approach for now and require outline instrumentation. Previous attempts allowed inline instrumentation. However, they came with some unfortunate restrictions: only physically contiguous memory could be used and it had to be specified at compile time. Maybe we can do better in the future. [paulus@ozlabs.org - Rebased onto 5.17. Note that a kernel with CONFIG_KASAN=y will crash during boot on a machine using HPT translation because not all the entry points to the generic KASAN code are protected with a call to kasan_arch_is_ready().] Originally-by: Balbir Singh <bsingharora@gmail.com> # ppc64 out-of-line radix version Signed-off-by: Daniel Axtens <dja@axtens.net> Signed-off-by: Paul Mackerras <paulus@ozlabs.org> [mpe: Update copyright year and comment formatting] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/YoTE69OQwiG7z+Gu@cleo |

KVM: PPC: Book3s: Remove real mode interrupt controller hcalls handlers
Currently we have 2 sets of interrupt controller hypercalls handlers for real and virtual modes, this is from POWER8 times when switching MMU on was considered an expensive operation. POWER9 however does not have dependent threads and MMU is enabled for handling hcalls so the XIVE native or XICS-on-XIVE real mode handlers never execute on real P9 and later CPUs. This untemplate the handlers and only keeps the real mode handlers for XICS native (up to POWER8) and remove the rest of dead code. Changes in functions are mechanical except few missing empty lines to make checkpatch.pl happy. The default implemented hcalls list already contains XICS hcalls so no change there. This should not cause any behavioral change.
