s390/pci: Allow automatic recovery with minimal driver support
According to Documentation/PCI/pci-error-recovery.rst only the error_detected() callback in the err_handler struct is mandatory for a driver to support error recovery. So far s390's error recovery chose a stricter approach also requiring slot_reset() and resume(). Relax this requirement and only require error_detected(). If a callback is not implemented EEH and AER treat this as PCI_ERS_RESULT_NONE. This return value is otherwise used by drivers abstaining from their vote on how to proceed with recovery and currently also not supported by s390's recovery code. So to support missing callbacks in-line with other implementors of the recovery flow, also handle PCI_ERS_RESULT_NONE. Since s390 only does per PCI function recovery and does not do voting, treat PCI_ERS_RESULT_NONE optimistically and proceed through recovery unless other failures prevent this.

s390/pci: Do not try re-enabling load/store if device is disabled
If a device is disabled unblocking load/store on its own is not useful
as a full re-enable of the function is necessary anyway. Note that SCLP
Write Event Data Action Qualifier 0 (Reset) leaves the device disabled
and triggers this case unless the driver already requests a reset.

s390/pci: Fix stale function handles in error handling
The error event information for PCI error events contains a function
handle for the respective function. This handle is generally captured at
the time the error event was recorded. Due to delays in processing or
cascading issues, it may happen that during firmware recovery multiple
events are generated. When processing these events in order Linux may
already have recovered an affected function making the event information
stale. Fix this by doing an unconditional CLP List PCI function
retrieving the current function handle with the zdev->state_lock held
and ignoring the event if its function handle is stale.

s390/ptrace: Fix pointer dereferencing in regs_get_kernel_stack_nth()
The recent change which added READ_ONCE_NOCHECK() to read the nth entry
from the kernel stack incorrectly dropped dereferencing of the stack
pointer in order to read the requested entry.
In result the address of the entry is returned instead of its content.
Dereference the pointer again to fix this.

mm: pgtable: fix pte_swp_exclusive
Make pte_swp_exclusive return bool instead of int. This will better reflect how pte_swp_exclusive is actually used in the code. This fixes swap/swapoff problems on Alpha due pte_swp_exclusive not returning correct values when _PAGE_SWP_EXCLUSIVE bit resides in upper 32-bits of PTE (like on alpha).

KVM: s390: rename PROT_NONE to PROT_TYPE_DUMMY
The enum type prot_type declared in arch/s390/kvm/gaccess.c declares an
unfortunate identifier within it - PROT_NONE.
This clashes with the protection bit define from the uapi for mmap()
declared in include/uapi/asm-generic/mman-common.h, which is indeed what
those casually reading this code would assume this to refer to.
This means that any changes which subsequently alter headers in any way
which results in the uapi header being imported here will cause build
errors.
Resolve the issue by renaming PROT_NONE to PROT_TYPE_DUMMY.

Generic:
* Clean up locking of all vCPUs for a VM by using the *_nest_lock()
family of functions, and move duplicated code to virt/kvm/.
kernel/ patches acked by Peter Zijlstra.
* Add MGLRU support to the access tracking perf test.
ARM fixes:
* Make the irqbypass hooks resilient to changes in the GSI<->MSI
routing, avoiding behind stale vLPI mappings being left behind. The
fix is to resolve the VGIC IRQ using the host IRQ (which is stable)
and nuking the vLPI mapping upon a routing change.
* Close another VGIC race where vCPU creation races with VGIC
creation, leading to in-flight vCPUs entering the kernel w/o private
IRQs allocated.
* Fix a build issue triggered by the recently added workaround for
Ampere's AC04_CPU_23 erratum.
* Correctly sign-extend the VA when emulating a TLBI instruction
potentially targeting a VNCR mapping.
* Avoid dereferencing a NULL pointer in the VGIC debug code, which can
happen if the device doesn't have any mapping yet.
s390:
* Fix interaction between some filesystems and Secure Execution
* Some cleanups and refactorings, preparing for an upcoming big series
x86:
* Wait for target vCPU to acknowledge KVM_REQ_UPDATE_PROTECTED_GUEST_STATE to
fix a race between AP destroy and VMRUN.
* Decrypt and dump the VMSA in dump_vmcb() if debugging enabled for the VM.
* Refine and harden handling of spurious faults.
* Add support for ALLOWED_SEV_FEATURES.
* Add #VMGEXIT to the set of handlers special cased for CONFIG_RETPOLINE=y.
* Treat DEBUGCTL[5:2] as reserved to pave the way for virtualizing features
that utilize those bits.
* Don't account temporary allocations in sev_send_update_data().
* Add support for KVM_CAP_X86_BUS_LOCK_EXIT on SVM, via Bus Lock Threshold.
* Unify virtualization of IBRS on nested VM-Exit, and cross-vCPU IBPB, between
SVM and VMX.
* Advertise support to userspace for WRMSRNS and PREFETCHI.
* Rescan I/O APIC routes after handling EOI that needed to be intercepted due
to the old/previous routing, but not the new/current routing.
* Add a module param to control and enumerate support for device posted
interrupts.
* Fix a potential overflow with nested virt on Intel systems running 32-bit kernels.
* Flush shadow VMCSes on emergency reboot.
* Add support for SNP to the various SEV selftests.
* Add a selftest to verify fastops instructions via forced emulation.
* Refine and optimize KVM's software processing of the posted interrupt bitmap, and share

Pull more kvm updates from Paolo Bonzini:
Generic:
- Clean up locking of all vCPUs for a VM by using the *_nest_lock()
family of functions, and move duplicated code to virt/kvm/. kernel/
patches acked by Peter Zijlstra
- Add MGLRU support to the access tracking perf test
ARM fixes:
- Make the irqbypass hooks resilient to changes in the GSI<->MSI
routing, avoiding behind stale vLPI mappings being left behind. The
fix is to resolve the VGIC IRQ using the host IRQ (which is stable)
and nuking the vLPI mapping upon a routing change
- Close another VGIC race where vCPU creation races with VGIC
creation, leading to in-flight vCPUs entering the kernel w/o
private IRQs allocated
- Fix a build issue triggered by the recently added workaround for
Ampere's AC04_CPU_23 erratum
- Correctly sign-extend the VA when emulating a TLBI instruction
potentially targeting a VNCR mapping
- Avoid dereferencing a NULL pointer in the VGIC debug code, which
can happen if the device doesn't have any mapping yet
s390:
- Fix interaction between some filesystems and Secure Execution
- Some cleanups and refactorings, preparing for an upcoming big
series
x86:
- Wait for target vCPU to ack KVM_REQ_UPDATE_PROTECTED_GUEST_STATE
to fix a race between AP destroy and VMRUN
- Decrypt and dump the VMSA in dump_vmcb() if debugging enabled for
the VM
- Refine and harden handling of spurious faults
- Add support for ALLOWED_SEV_FEATURES
- Add #VMGEXIT to the set of handlers special cased for
CONFIG_RETPOLINE=y
- Treat DEBUGCTL[5:2] as reserved to pave the way for virtualizing
features that utilize those bits
- Don't account temporary allocations in sev_send_update_data()
- Add support for KVM_CAP_X86_BUS_LOCK_EXIT on SVM, via Bus Lock
Threshold
- Unify virtualization of IBRS on nested VM-Exit, and cross-vCPU
IBPB, between SVM and VMX
- Advertise support to userspace for WRMSRNS and PREFETCHI
- Rescan I/O APIC routes after handling EOI that needed to be
intercepted due to the old/previous routing, but not the
new/current routing
- Add a module param to control and enumerate support for device
posted interrupts
- Fix a potential overflow with nested virt on Intel systems running
32-bit kernels
- Flush shadow VMCSes on emergency reboot
- Add support for SNP to the various SEV selftests
- Add a selftest to verify fastops instructions via forced emulation
- Refine and optimize KVM's software processing of the posted
interrupt bitmap, and share the harvesting code between KVM and the
kernel's Posted MSI handler"

- The 11 patch series "Add folio_mk_pte()" from Matthew Wilcox
simplifies the act of creating a pte which addresses the first page in a folio and reduces the amount of plumbing which architecture must implement to provide this. - The 8 patch series "Misc folio patches for 6.16" from Matthew Wilcox is a shower of largely unrelated folio infrastructure changes which clean things up and better prepare us for future work. - The 3 patch series "memory,x86,acpi: hotplug memory alignment advisement" from Gregory Price adds early-init code to prevent x86 from leaving physical memory unused when physical address regions are not aligned to memory block size. - The 2 patch series "mm/compaction: allow more aggressive proactive compaction" from Michal Clapinski provides some tuning of the (sadly, hard-coded (more sadly, not auto-tuned)) thresholds for our invokation of proactive compaction. In a simple test case, the reduction of a guest VM's memory consumption was dramatic. - The 8 patch series "Minor cleanups and improvements to swap freeing code" from Kemeng Shi provides some code cleaups and a small efficiency improvement to this part of our swap handling code. - The 6 patch series "ptrace: introduce PTRACE_SET_SYSCALL_INFO API" from Dmitry Levin adds the ability for a ptracer to modify syscalls arguments. At this time we can alter only "system call information that are used by strace system call tampering, namely, syscall number, syscall arguments, and syscall return value. This series should have been incorporated into mm.git's "non-MM" branch, but I goofed. - The 3 patch series "fs/proc: extend the PAGEMAP_SCAN ioctl to report guard regions" from Andrei Vagin extends the info returned by the PAGEMAP_SCAN ioctl against /proc/pid/pagemap. This permits CRIU to more efficiently get at the info about guard regions. - The 2 patch series "Fix parameter passed to page_mapcount_is_type()" from Gavin Shan implements that fix. No runtime effect is expected because validate_page_before_insert() happens to fix up this error. - The 3 patch series "kernel/events/uprobes: uprobe_write_opcode() rewrite" from David Hildenbrand basically brings uprobe text poking into the current decade. Remove a bunch of hand-rolled implementation in favor of using more current facilities. - The 3 patch series "mm/ptdump: Drop assumption that pxd_val() is u64" from Anshuman Khandual provides enhancements and generalizations to the pte dumping code. This might be needed when 128-bit Page Table Descriptors are enabled for ARM. - The 12 patch series "Always call constructor for kernel page tables" from Kevin Brodsky "ensures that the ctor/dtor is always called for kernel pgtables, as it already is for user pgtables". This permits the addition of more functionality such as "insert hooks to protect page tables". This change does result in various architectures performing unnecesary work, but this is fixed up where it is anticipated to occur. - The 9 patch series "Rust support for mm_struct, vm_area_struct, and mmap" from Alice Ryhl adds plumbing to permit Rust access to core MM structures. - The 3 patch series "fix incorrectly disallowed anonymous VMA merges" from Lorenzo Stoakes takes advantage of some VMA merging opportunities which we've been missing for 15 years. - The 4 patch series "mm/madvise: batch tlb flushes for MADV_DONTNEED and MADV_FREE" from SeongJae Park optimizes process_madvise()'s TLB flushing.

This directs proactive reclaim to reclaim from only anon folios rather than file-backed folios. - The 17 patch series "kexec: introduce Kexec HandOver (KHO)" from Mike Rapoport is the first step on the path to permitting the kernel to maintain existing VMs while replacing the host kernel via file-based kexec. At this time only memblock's reserve_mem is preserved. - The 7 patch series "mm: Introduce for_each_valid_pfn()" from David Woodhouse provides and uses a smarter way of looping over a pfn range. By skipping ranges of invalid pfns. - The 2 patch series "sched/numa: Skip VMA scanning on memory pinned to one NUMA node via cpuset.mems" from Libo Chen removes a lot of pointless VMA scanning when a task is pinned a single NUMA mode.

The latter is more restrictive and prevents drivers from messing with things in ways which, amongst other problems, may defeat VMA merging. - The 4 patch series "memcg: decouple memcg and objcg stocks"" from Shakeel Butt decouples the per-cpu memcg charge cache from the objcg's one. This is a step along the way to making memcg and objcg charging NMI-safe, which is a BPF requirement. - The 6 patch series "mm/damon: minor fixups and improvements for code, tests, and documents" from SeongJae Park is "yet another batch of miscellaneous DAMON changes.

crypto: s390/sha256 - rename module to sha256-s390
When the s390 SHA-256 code is built as a loadable module, name it
sha256-s390.ko instead of sha256.ko. This avoids a module name
collision with crypto/sha256.ko and makes it consistent with the other
architectures.
We should consider making a single module provide all the SHA-256
library code, which would prevent issues like this. But for now this is
the fix that's needed.
Fixes:

KVM: s390: Refactor and split some gmap helpers
Refactor some gmap functions; move the implementation into a separate file with only helper functions. The new helper functions work on vm addresses, leaving all gmap logic in the gmap functions, which mostly become just wrappers. The whole gmap handling is going to be moved inside KVM soon, but the helper functions need to touch core mm functions, and thus need to stay in the core of kernel.

s390/uv: Improve splitting of large folios that cannot be split while dirty
Currently, starting a PV VM on an iomap-based filesystem with large folio support, such as XFS, will not work. We'll be stuck in unpack_one()->gmap_make_secure(), because we can't seem to make progress splitting the large folio. The problem is that we require a writable PTE but a writable PTE under such filesystems will imply a dirty folio. So whenever we have a writable PTE, we'll have a dirty folio, and dirty iomap folios cannot currently get split, because split_folio()->split_huge_page_to_list_to_order()->filemap_release_folio() will fail in iomap_release_folio(). So we will not make any progress splitting such large folios. Until dirty folios can be split more reliably, let's manually trigger writeback of the problematic folio using filemap_write_and_wait_range(), and retry the split immediately afterwards exactly once, before looking up the folio again. Should this logic be part of split_folio()? Likely not; most split users don't have to split so eagerly to make any progress. For now, this seems to affect xfs, zonefs and erofs, and this patch makes it work again (tested on xfs only). While this could be considered a fix for commit |

s390/uv: Always return 0 from s390_wiggle_split_folio() if successful
Let's consistently return 0 if the operation was successful, and just detect ourselves whether splitting is required -- folio_test_large() is a cheap operation. Update the documentation. Should we simply always return -EAGAIN instead of 0, so we don't have to handle it in the caller? Not sure, staring at the documentation, this way looks a bit cleaner.

s390/uv: Don't return 0 from make_hva_secure() if the operation was not successful
If s390_wiggle_split_folio() returns 0 because splitting a large folio
succeeded, we will return 0 from make_hva_secure() even though a retry
is required. Return -EAGAIN in that case.
Otherwise, we'll return 0 from gmap_make_secure(), and consequently from
unpack_one(). In kvm_s390_pv_unpack(), we assume that unpacking
succeeded and skip unpacking this page. Later on, we run into issues
and fail booting the VM.
So far, this issue was only observed with follow-up patches where we
split large pagecache XFS folios. Maybe it can also be triggered with
shmem?
We'll cleanup s390_wiggle_split_folio() a bit next, to also return 0
if no split was required.

We expose a set of functions with names containing "lookup_one_len" and others without the "_len". This difference has nothing to do with "len".

A related question is "is permission checking relevant here?". nfsd and cachefiles *do* have a vfsmount but *don't* use the non-_len functions. They pass nop_mnt_idmap and refuse to work on filesystems which have any other idmap. This work changes nfsd and cachefile to use the lookup_one family of functions and to explictily pass &nop_mnt_idmap which is consistent with all other vfs interfaces used where &nop_mnt_idmap is explicitly passed.

s390: always declare expoline thunks
It would be convenient to use the following pattern in the BPF JIT:
if (nospec_uses_trampoline())
emit_call(__s390_indirect_jump_r1);
Unfortunately with CONFIG_EXPOLINE=n the compiler complains about the
missing prototype of __s390_indirect_jump_r1(). One could wrap the
whole "if" statement in an #ifdef, but this clutters the code.
Instead, declare expoline thunk prototypes even when compiling without
expolines. When using the above code structure and compiling without
expolines, references to them are optimized away, and there are no
linker errors.

s390/pci: Serialize device addition and removal
Prior changes ensured that when zpci_release_device() is called and it
removed the zdev from the zpci_list this instance can not be found via
the zpci_list anymore even while allowing re-add of reserved devices.
This only accounts for the overall lifetime and zpci_list addition and
removal, it does not yet prevent concurrent add of a new instance for
the same underlying device. Such concurrent add would subsequently cause
issues such as attempted re-use of the same IOMMU sysfs directory and is
generally undesired.
Introduce a new zpci_add_remove_lock mutex to serialize adding a new
device with removal. Together this ensures that if a struct zpci_dev is
not found in the zpci_list it was either already removed and torn down,
or its removal and tear down is in progress with the
zpci_add_remove_lock held.

s390/pci: Allow re-add of a reserved but not yet removed device
The architecture assumes that PCI functions can be removed synchronously as PCI events are processed. This however clashes with the reference counting of struct pci_dev which allows device drivers to hold on to a struct pci_dev reference even as the underlying device is removed.

s390/pci: Fix __pcilg_mio_inuser() inline assembly
Use "a" constraint for the shift operand of the __pcilg_mio_inuser() inline
assembly. The used "d" constraint allows the compiler to use any general
purpose register for the shift operand, including register zero.
If register zero is used this my result in incorrect code generation:
8f6: a7 0a ff f8 ahi %r0,-8
8fa: eb 32 00 00 00 0c srlg %r3,%r2,0 <----
If register zero is selected to contain the shift value, the srlg
instruction ignores the contents of the register and always shifts zero
bits. Therefore use the "a" constraint which does not permit to select
register zero.

s390/ptrace: Always inline regs_get_kernel_stack_nth() and regs_get_register()
Both regs_get_kernel_stack_nth() and regs_get_register() are not
inlined. With the new ftrace funcgraph-args feature they show up in
function graph tracing:
4) | sched_core_idle_cpu(cpu=4) {
4) 0.257 us | regs_get_register(regs=0x37fe00afa10, offset=2);
4) 0.218 us | regs_get_register(regs=0x37fe00afa10, offset=3);
4) 0.225 us | regs_get_register(regs=0x37fe00afa10, offset=4);
4) 0.239 us | regs_get_register(regs=0x37fe00afa10, offset=5);
4) 0.239 us | regs_get_register(regs=0x37fe00afa10, offset=6);
4) 0.245 us | regs_get_kernel_stack_nth(regs=0x37fe00afa10, n=20);
This is subtoptimal, since both functions are supposed to be ftrace
internal helper functions. If they appear in ftrace traces this reduces
readability significantly, plus this adds tons of extra useless extra
entries.
Address this by moving both functions and required helpers to ptrace.h and
always inline them. This way they don't appear in traces anymore. In
addition the overhead that comes with functions calls is also reduced.

s390/extmem: Add workaround for DCSS unload diag
When calling the diag for DCSS unload on a non-IPL CPU, the sclp maximum memory detection on the next IPL would falsely return the end of the previously loaded DCSS. This is because of an issue in z/VM, so work around it by always calling the diag for DCSS unload on IPL CPU 0. That CPU cannot be set offline, so the dcss_diag() call can directly be scheduled to CPU 0. The wrong maximum memory value returned by sclp would only affect KASAN kernels. When a DCSS within the falsely reported extra memory range is loaded and accessed again, it would result in a kernel crash: Unable to handle kernel pointer dereference in virtual kernel address space Failing address: 001c0000a3ffe000 TEID: 001c0000a3ffe803 Fault in home space mode while using kernel ASCE.

s390/crypto: Rework protected key AES for true asynch support
This is a complete rework of the protected key AES (PAES) implementation. The goal of this rework is to implement the 4 modes (ecb, cbc, ctr, xts) in a real asynchronous fashion: - init(), exit() and setkey() are synchronous and don't allocate any memory. - the encrypt/decrypt functions first try to do the job in a synchronous manner. If this fails, for example the protected key got invalid caused by a guest suspend/resume or guest migration action, the encrypt/decrypt is transferred to an instance of the crypto engine (see below) for asynchronous processing. These postponed requests are then handled by the crypto engine by invoking the do_one_request() callback but may of course again run into a still not converted key or the key is getting invalid. If the key is still not converted, the first thread does the conversion and updates the key status in the transformation context. The conversion is invoked via pkey API with a new flag PKEY_XFLAG_NOMEMALLOC. Note that once there is an active requests enqueued to get async processed via crypto engine, further requests also need to go via crypto engine to keep the request sequence. This patch together with the pkey/zcrypt/AP extensions to support the new PKEY_XFLAG_NOMEMMALOC should toughen the paes crypto algorithms to truly meet the requirements for in-kernel skcipher implementations and the usage patterns for the dm-crypt and dm-integrity layers.
