      The root cause is that HWPoison flag will be set for huge_zero_folio
      without increasing the folio refcnt.  But then unpoison_memory() will
      decrease the folio refcnt unexpectedly as it appears like a successfully
      hwpoisoned folio leading to VM_BUG_ON_PAGE(page_ref_count(page) == 0) when
      releasing huge_zero_folio.
      
      Skip unpoisoning huge_zero_folio in unpoison_memory() to fix this issue. 
      We're not prepared to unpoison huge_zero_folio yet.

      kasan, fortify: properly rename memintrinsics · 2e577732
      Andrey Konovalov authored
      After commit 69d4c0d3 ("entry, kasan, x86: Disallow overriding mem*()
      functions") and the follow-up fixes, with CONFIG_FORTIFY_SOURCE enabled,
      even though the compiler instruments meminstrinsics by generating calls to
      __asan/__hwasan_ prefixed functions, FORTIFY_SOURCE still uses
      uninstrumented memset/memmove/memcpy as the underlying functions.
      
      As a result, KASAN cannot detect bad accesses in memset/memmove/memcpy. 
      This also makes KASAN tests corrupt kernel memory and cause crashes.
      
      To fix this, use __asan_/__hwasan_memset/memmove/memcpy as the underlying
      functions whenever appropriate.  Do this only for the instrumented code
      (as indicated by __SANITIZE_ADDRESS__).

      mm/vmalloc: fix vmalloc which may return null if called with __GFP_NOFAIL · 8e0545c8
      Hailong.Liu authored
      commit a421ef30 ("mm: allow !GFP_KERNEL allocations for kvmalloc")
      includes support for __GFP_NOFAIL, but it presents a conflict with commit
      dd544141 ("vmalloc: back off when the current task is OOM-killed").  A
      possible scenario is as follows:
      
      process-a
      __vmalloc_node_range(GFP_KERNEL | __GFP_NOFAIL)
          __vmalloc_area_node()
              vm_area_alloc_pages()
      		--> oom-killer send SIGKILL to process-a
              if (fatal_signal_pending(current)) break;
      --> return NULL;
      
      To fix this, do not check fatal_signal_pending() in vm_area_alloc_pages()
      if __GFP_NOFAIL set.
      
      This issue occurred during OPLUS KASAN TEST. Below is part of the log
      -> oom-killer sends signal to process

       - A series ("kbuild: enable more warnings by default") from Arnd

         fixed all the fallout which we could find, there may still be a few
         stragglers.
      
       - Samuel Holland has developed the series "Unified cross-architecture
         kernel-mode FPU API". This does a lot of consolidation of
         per-architecture kernel-mode FPU usage and enables the use of newer
         AMD GPUs on RISC-V.

      mm: simplify and improve print_vma_addr() output · de7e71ef
      Linus Torvalds authored
      Use '%pD' to print out the filename, and print out the actual offset
      within the file too, rather than just what the virtual address of the
      mapping is (which doesn't tell you anything about any mapping offsets).
      
      Also, use the exact vma_lookup() instead of find_vma() - the latter
      looks up any vma _after_ the address, which is of questionable value
      (yes, maybe you fell off the beginning, but you'd be more likely to fall
      off the end).

      Merge trivial x86 code generation annoyances
      
       - Introduce helper macros for clang asm input problems
      
       - use said macros to improve trivially stupid code generation issues in
         bitops and array_index_mask_nospec
      
       - also improve codegen with 32-bit array index comparisons
      
      None of these really matter, but I look at code generation and profiles
      fairly regularly, and these misfeatures caused the generated code to
      look really odd and distract from the real issues.

      x86: improve bitop code generation with clang · b9b60b31
      Linus Torvalds authored
      This uses the new ASM_INPUT_RM macro to avoid the bad code generation
      issue that clang has with more generic asm inputs.
      
      This ends up avoiding generating code like this:
      
       	mov    %r10,(%rsp)
       	tzcnt  (%rsp),%rcx
      
      which now becomes just
      
       	tzcnt  %r10,%rcx
      
      and in the process ends up also removing a few unnecessary stack frames
      when the only use was that pointless "asm uses memory location off stack".

      x86: improve array_index_mask_nospec() code generation · 7453b948
      Linus Torvalds authored
      Don't force the inputs to be 'unsigned long', when the comparison can
      easily be done in 32-bit if that's more appropriate.
      
      Note that while we can look at the inputs to choose an appropriate size
      for the compare instruction, the output is fixed at 'unsigned long'.
      That's not technically optimal either, since a 32-bit 'sbbl' would often
      be sufficient.
      
      But for the outgoing mask we don't know how the mask ends up being used
      (ie we have uses that have an incoming 32-bit array index, but end up
      using the mask for other things).  That said, it only costs the extra
      REX prefix to always generate the 64-bit mask.
      
      [ A 'sbbl' also always technically generates a 64-bit mask, but with the
        upper 32 bits clear: that's fine for when the incoming index that will
        be masked is already 32-bit, but not if you use the mask to mask a
        pointer afterwards, like the file table lookup does ]

      clang: work around asm input constraint problems · dbaaabd6
      Linus Torvalds authored
      Work around clang problems with asm constraints that have multiple
      possibilities, particularly "g" and "rm".
      
      Clang seems to turn inputs like that into the most generic form, which
      is the memory input - but to make matters worse, clang won't even use a
      possible original memory location, but will spill the value to stack,
      and use the stack for the asm input.
      
      See
      
        https://github.com/llvm/llvm-project/issues/20571#issuecomment-980933442
      
      for some explanation of why clang has this strange behavior, but the end
      result is that "g" and "rm" really end up generating horrid code.

      vfs: Delete the associated dentry when deleting a file · 681ce862
      Yafang Shao authored
      Our applications, built on Elasticsearch[0], frequently create and
      delete files.  These applications operate within containers, some with a
      memory limit exceeding 100GB.  Over prolonged periods, the accumulation
      of negative dentries within these containers can amount to tens of
      gigabytes.
      
      Upon container exit, directories are deleted.  However, due to the
      numerous associated dentries, this process can be time-consuming.  Our
      users have expressed frustration with this prolonged exit duration,
      which constitutes our first issue.
      
      Simultaneously, other processes may attempt to access the parent
      directory of the Elasticsearch directories.  Since the task responsible
      for deleting the dentries holds the inode lock, processes attempting
      directory lookup experience significant delays.  This issue, our second
      problem, is easily demonstrated:
      
        - Task 1 generates negative dentries:
        $ pwd
        ~/test
        $ mkdir es && cd es/ && ./create_and_delete_files.sh
      
        [ After generating tens of GB dentries ]
      
        $ cd ~/test && rm -rf es
      
        [ It will take a long duration to finish ]
      
        - Task 2 attempts to lookup the 'test/' directory
        $ pwd
        ~/test
        $ ls
      
        The 'ls' command in Task 2 experiences prolonged execution as Task 1
        is deleting the dentries.
      
      We've devised a solution to address both issues by deleting associated
      dentry when removing a file.  Interestingly, we've noted that a similar
      patch was proposed years ago[1], although it was rejected citing the
      absence of tangible issues caused by negative dentries.  Given our
      current challenges, we're resubmitting the proposal.  All relevant
      stakeholders from previous discussions have been included for reference.
      
      Some alternative solutions are also under discussion[2][3], such as
      shrinking child dentries outside of the parent inode lock or even
      asynchronously shrinking child dentries.  However, given the
      straightforward nature of the current solution, I believe this approach
      is still necessary.
      
      [ NOTE! This is a pretty fundamental change in how we deal with
        unlinking dentries, and it doesn't change the fact that you can have
        lots of negative dentries from just doing negative lookups.
      
        But the kernel test robot is at least initially happy with this from a
        performance angle, so I'm applying this ASAP just to get more testing
        and as a "known fix for an issue people hit in real life".
      
        Put another way: we should still look at the alternatives, and this
        patch may get reverted if somebody finds a performance regression on
        some other load.       - Linus ]

      Merge tag 'perf-tools-for-v6.10-1-2024-05-21' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools
      
      Pull perf tools updates from Arnaldo Carvalho de Melo:
       "General:
      
         - Integrate the shellcheck utility with the build of perf to allow
           catching shell problems early in areas such as 'perf test', 'perf
           trace' scrape scripts, etc
      
         - Add 'uretprobe' variant in the 'perf bench uprobe' tool
      
         - Add script to run instances of 'perf script' in parallel
      
         - Allow parsing tracepoint names that start with digits, such as
           9p/9p_client_req, etc. Make sure 'perf test' tests it even on
           systems where those tracepoints aren't available
      
         - Add Kan Liang to MAINTAINERS as a perf tools reviewer
      
         - Add support for using the 'capstone' disassembler library in
           various tools, such as 'perf script' and 'perf annotate'. This is
           an alternative for the use of the 'xed' and 'objdump' disassemblers
      
        Data-type profiling improvements:
      
         - Resolve types for a->b->c by backtracking the assignments until it
           finds DWARF info for one of those members
      
         - Support for global variables, keeping a cache to speed up lookups
      
         - Handle the 'call' instruction, dealing with effects on registers
           and handling its return when tracking register data types
      
         - Handle x86's segment based addressing like %gs:0x28, to support
           things like per CPU variables, the stack canary, etc
      
         - Data-type profiling got big speedups when using capstone for
           disassembling. The objdump outoput parsing method is left as a
           fallback when capstone fails or isn't available. There are patches
           posted for 6.11 that to use a LLVM disassembler
      
         - Support event group display in the TUI when annotating types with
           --data-type, for instance to show memory load and store events for
           the data type fields
      
         - Optimize the 'perf annotate' data structures, reducing memory usage
      
         - Add a initial 'perf test' for 'perf annotate', checking that a
           target symbol appears on the output, specifying objdump via the
           command line, etc
      
        Vendor Events:
      
         - Update Intel JSON files for Cascade Lake X, Emerald Rapids, Grand
           Ridge, Ice Lake X, Lunar Lake, Meteor Lake, Sapphire Rapids, Sierra
           Forest, Sky Lake X, Sky Lake and Snow Ridge X. Remove info metrics
           erroneously in TopdownL1
      
         - Add AMD's Zen 5 core and uncore events and metrics. Those come from
           the "Performance Monitor Counters for AMD Family 1Ah Model 00h- 0Fh
           Processors" document, with events that capture information on op
           dispatch, execution and retirement, branch prediction, L1 and L2
           cache activity, TLB activity, etc
      
         - Mark L1D_CACHE_INVAL impacted by errata for ARM64's AmpereOne/
           AmpereOneX
      
        Miscellaneous:
      
         - Sync header copies with the kernel sources
      
         - Move some header copies used only for generating translation string
           tables for ioctl cmds and other syscall integer arguments to a new
           directory under tools/perf/beauty/, to separate from copies in
           tools/include/ that are used to build the tools
      
         - Introduce scrape script for several syscall 'flags'/'mask'
           arguments
      
         - Improve cpumap utilization, fixing up pairing of refcounts, using
           the right iterators (perf_cpu_map__for_each_cpu), etc
      
         - Give more details about raw event encodings in 'perf list', show
           tracepoint encoding in the detailed output
      
         - Refactor the DSOs handling code, reducing memory usage
      
         - Document the BPF event modifier and add a 'perf test' for it
      
         - Improve the event parser, better error messages and add further
           'perf test's for it
      
         - Add reference count checking to 'struct comm_str' and 'struct
           mem_info'
      
         - Make ARM64's 'perf test' entries for the Neoverse N1 more robust
      
         - Tweak the ARM64's Coresight 'perf test's
      
         - Improve ARM64's CoreSight ETM version detection and error reporting
      
         - Fix handling of symbols when using kcore
      
         - Fix PAI (Processor Activity Instrumentation) counter names for s390
           virtual machines in 'perf report'
      
         - Fix -g/--call-graph option failure in 'perf sched timehist'
      
         - Add LIBTRACEEVENT_DIR build option to allow building with
           libtraceevent installed in non-standard directories, such as when
           doing cross builds
      
         - Various 'perf test' and 'perf bench' fixes
      
         - Improve 'perf probe' error message for long C++ probe names"

      Linus Torvalds authored
      Pull more s390 updates from Alexander Gordeev:
      
       - Switch read and write software bits for PUDs
      
       - Add missing hardware bits for PUDs and PMDs
      
       - Generate unwind information for C modules to fix GDB unwind error for
         vDSO functions
      
       - Create .build-id links for unstripped vDSO files to enable vDSO
         debugging with symbols
      
       - Use standard stack frame layout for vDSO generated stack frames to
         manually walk stack frames without DWARF information
      
       - Rework perf_callchain_user() and arch_stack_walk_user() functions to
         reduce code duplication
      
       - Skip first stack frame when walking user stack
      
       - Add basic checks to identify invalid instruction pointers when
         walking stack frames
      
       - Introduce and use struct stack_frame_vdso_wrapper within vDSO user
         wrapper code to automatically generate an asm-offset define. Also use
         STACK_FRAME_USER_OVERHEAD instead of STACK_FRAME_OVERHEAD to document
         that the code works with user space stack
      
       - Clear the backchain of the extra stack frame added by the vDSO user
         wrapper code. This allows the user stack walker to detect and skip
         the non-standard stack frame. Without this an incorrect instruction
         pointer would be added to stack traces.
      
       - Rewrite psw_idle() function in C to ease maintenance and further
         enhancements
      
       - Remove get_vtimer() function and use get_cpu_timer() instead
      
       - Mark psw variable in __load_psw_mask() as __unitialized to avoid
         superfluous clearing of PSW
      
       - Remove obsolete and superfluous comment about removed TIF_FPU flag
      
       - Replace memzero_explicit() and kfree() with kfree_sensitive() to fix
         warnings reported by Coccinelle
      
       - Wipe sensitive data and all copies of protected- or secure-keys from
         stack when an IOCTL fails
      
       - Both do_airq_interrupt() and do_io_interrupt() functions set
         CIF_NOHZ_DELAY flag. Move it in do_io_irq() to simplify the code
      
       - Provide iucv_alloc_device() and iucv_release_device() helpers, which
         can be used to deduplicate more or less identical IUCV device
         allocation and release code in four different drivers
      
       - Make use of iucv_alloc_device() and iucv_release_device() helpers to
         get rid of quite some code and also remove a cast to an incompatible
         function (clang W=1)
      
       - There is no user of iucv_root outside of the core IUCV code left.
         Therefore remove the EXPORT_SYMBOL
      
       - __apply_alternatives() contains a runtime check which verifies that
         the size of the to be patched code area is even. Convert this to a
         compile time check
      
       - Increase size of buffers for sending z/VM CP DIAGNOSE X'008' commands
         from 128 to 240
      
       - Do not accept z/VM CP DIAGNOSE X'008' commands longer than maximally
         allowed
      
       - Use correct defines IPL_BP_NVME_LEN and IPL_BP0_NVME_LEN instead of
         IPL_BP_FCP_LEN and IPL_BP0_FCP_LEN ones to initialize NVMe reIPL
         block on 'scp_data' sysfs attribute update
      
       - Initialize the correct fields of the NVMe dump block, which were
         confused with FCP fields
      
       - Refactor macros for 'scp_data' (re-)IPL sysfs attribute to reduce
         code duplication
      
       - Introduce 'scp_data' sysfs attribute for dump IPL to allow tools such
         as dumpconf passing additional kernel command line parameters to a
         stand-alone dumper
      
       - Rework the CPACF query functions to use the correct RRE or RRF
         instruction formats and set instruction register fields correctly
      
       - Instead of calling BUG() at runtime force a link error during compile
         when a unsupported opcode is used with __cpacf_query() or
         __cpacf_check_opcode() functions
      
       - Fix a crash in ap_parse_bitmap_str() function on /sys/bus/ap/apmask
         or /sys/bus/ap/aqmask sysfs file update with a relative mask value
      
       - Fix "bindings complete" udev event which should be sent once all AP
         devices have been bound to device drivers and again when unbind/bind
         actions take place and all AP devices are bound again
      
       - Facility list alt_stfle_fac_list is nowhere used in the decompressor,
         therefore remove it there
      
       - Remove custom kprobes insn slot allocator in favour of the standard
         module_alloc() one, since kernel image and module areas are located
         within 4GB
      
       - Use kvcalloc() instead of kvmalloc_array() in zcrypt driver to avoid
         calling memset() with a large byte count and get rid of the sparse
         warning as result
