      Pull tomoyo updates from Tetsuo Handa:
       "One bugfix patch, one preparation patch, and one conversion patch.
      
        TOMOYO is useful as an analysis tool for learning how a Linux system
        works. My boss was hoping that SELinux's policy is generated from what
        TOMOYO has observed. A translated paper describing it is available at
      
          https://master.dl.sourceforge.net/project/tomoyo/docs/nsf2003-en.pdf/nsf2003-en.pdf?viasf=1
      
        Although that attempt failed due to mapping problem between inode and
        pathname, TOMOYO remains as an access restriction tool due to ability
        to write custom policy by individuals.
      
        I was delivering pure LKM version of TOMOYO (named AKARI) to users who
        cannot afford rebuilding their distro kernels with TOMOYO enabled. But
        since the LSM framework was converted to static calls, it became more
        difficult to deliver AKARI to such users. Therefore, I decided to
        update TOMOYO so that people can use mostly LKM version of TOMOYO with
        minimal burden for both distributors and users"

      Pull compute express link (cxl) updates from Dave Jiang:
       "Major changes address HDM decoder initialization from DVSEC ranges,
        refactoring the code related to cxl mailboxes to be independent of the
        memory devices, and adding support for shared upstream link
        access_coordinate calculation, as well as a change to remove locking
        from memory notifier callback.
      
        In addition, a number of misc cleanups and refactoring of the code are
        also included.
      
        Address HDM decoder initialization from DVSEC ranges:
         - Only register non-zero DVSEC ranges
         - Remove duplicate implementation of waiting for memory_info_valid
         - Simplify the checking of mem_enabled in  cxl_hdm_decode_init()
      
        Refactor the code related to cxl mailboxes to be independent of the memory devices:
         - Move cxl headers in include/linux/ to include/cxl
         - Move all mailbox related data to 'struct cxl_mailbox'
         - Refactor mailbox APIs with 'struct cxl_mailbox' as input instead of
           memory device state
      
        Add support for shared upstream link access_coordinate calculation for
        configurations that have multiple targets under a switch or a root
        port where the aggregated bandwidth can be greater than the upstream
        link of the switch/RP upstream link:
         - Preserve the CDAT access_coordinate from an endpoint
         - Add the support for shared upstream link access_coordinate calculation
         - Add documentation to explain how the calculations are done
      
        Remove locking from memory notifier callback.
      
        Misc cleanups:
         - Convert devm_cxl_add_root() to return using ERR_CAST()
         - cxl_test use dev_is_platform() instead of open coding
         - Remove duplicate include of header core.h in core/cdat.c
         - use scoped resource management to drop put_device() for cxl_port
         - Use scoped_guard to drop device_lock() for cxl_port
         - Refactor __devm_cxl_add_port() to drop gotos
         - Rename cxl_setup_parent_dport to cxl_dport_init_aer and
           cxl_dport_map_regs() to cxl_dport_map_ras()
         - Refactor cxl_dport_init_aer() to be more concise
         - Remove duplicate host_bridge->native_aer checking in
           cxl_dport_init_ras_reporting()
         - Fix comment for cxl_query_cmd()"

        of last-minute reports of problems in the async shutdown feature that
        was added. In the end, I've reverted all of the patches in that series
        so we are back to "normal" and the patch set is being reworked for the

      [tree-wide] finally take no_llseek out · cb787f4a
      Al Viro authored
      no_llseek had been defined to NULL two years ago, in commit 868941b1
      ("fs: remove no_llseek")
      
      To quote that commit,
      
        At -rc1 we'll need do a mechanical removal of no_llseek -
      
        git grep -l -w no_llseek | grep -v porting.rst | while read i; do
      	sed -i '/\<no_llseek\>/d' $i
        done
      
        would do it.
      
      Unfortunately, that hadn't been done.  Linus, could you do that now, so
      that we could finally put that thing to rest? All instances are of the
      form
      	.llseek = no_llseek,
      so it's obviously safe.

      This is because when ocfs2_extent_map_get_blocks() fails, p_blkno is
      uninitialized.  So the error log will trigger the above uninit-value
      access.
      
      The error log is out-of-date since get_blocks() was removed long time ago.
      And the error code will be logged in ocfs2_extent_map_get_blocks() once
      ocfs2_get_cluster() fails, so fix this by only logging inode and block.

      Andrey Skvortsov authored
      When CONFIG_ZRAM_MULTI_COMP isn't set ZRAM_SECONDARY_COMP can hold
      default_compressor, because it's the same offset as ZRAM_PRIMARY_COMP, so
      we need to make sure that we don't attempt to kfree() the statically
      defined compressor name.

      The number is dependent on the architecture. The above data shows that:

      x86_64	323
      
      The value of __NR_userfaultfd was changed to 282 when asm-generic/unistd.h
      was included.  It makes the test to fail every time as the correct number
      of this syscall on x86_64 is 323.  Fix the header to asm/unistd.h.

      compiler.h: specify correct attribute for .rodata..c_jump_table · c5b1184d
      Tiezhu Yang authored
      Currently, there is an assembler message when generating kernel/bpf/core.o
      under CONFIG_OBJTOOL with LoongArch compiler toolchain:
      
        Warning: setting incorrect section attributes for .rodata..c_jump_table
      
      This is because the section ".rodata..c_jump_table" should be readonly,
      but there is a "W" (writable) part of the flags:
      
        $ readelf -S kernel/bpf/core.o | grep -A 1 "rodata..c"
        [34] .rodata..c_j[...] PROGBITS         0000000000000000  0000d2e0
             0000000000000800  0000000000000000  WA       0     0     8
      
      There is no above issue on x86 due to the generated section flag is only
      "A" (allocatable). In order to silence the warning on LoongArch, specify
      the attribute like ".rodata..c_jump_table,\"a\",@progbits #" explicitly,
      then the section attribute of ".rodata..c_jump_table" must be readonly
      in the kernel/bpf/core.o file.
      
      Before:
      
        $ objdump -h kernel/bpf/core.o | grep -A 1 "rodata..c"
         21 .rodata..c_jump_table 00000800  0000000000000000  0000000000000000  0000d2e0  2**3
                        CONTENTS, ALLOC, LOAD, RELOC, DATA
      
      After:
      
        $ objdump -h kernel/bpf/core.o | grep -A 1 "rodata..c"
         21 .rodata..c_jump_table 00000800  0000000000000000  0000000000000000  0000d2e0  2**3
                        CONTENTS, ALLOC, LOAD, RELOC, READONLY, DATA
      
      By the way, AFAICT, maybe the root cause is related with the different
      compiler behavior of various archs, so to some extent this change is a
      workaround for LoongArch, and also there is no effect for x86 which is the
      only port supported by objtool before LoongArch with this patch.

      syzbot has found a possible deadlock in ocfs2_get_system_file_inode [1].
      
      The scenario is depicted here,

      lock(&ocfs2_file_ip_alloc_sem_key);

      lock(&osb->system_file_mutex);
      
      The function calls which could lead to this are:

      ocfs2_mknod - lock(&ocfs2_file_ip_alloc_sem_key);
      .

      .
      ocfs2_read_virt_blocks - lock(&ocfs2_file_ip_alloc_sem_key);
      
      This issue can be resolved by making the down_read -> down_read_try
      in the ocfs2_read_virt_blocks.

      The issue was in the reflink workfow while reserving space for inline
      xattr.  The problematic function is ocfs2_reflink_xattr_inline().  By the
      time this function is called the reflink tree is already recreated at the
      destination inode from the source inode.  At this point, this function
      reserves space for inline xattrs at the destination inode without even
      checking if there is space at the root metadata block.  It simply reduces
      the l_count from 243 to 227 thereby making space of 256 bytes for inline
      xattr whereas the inode already has extents beyond this index (in this
      case up to 230), thereby causing corruption.
      
      The fix for this is to reserve space for inline metadata at the destination
      inode before the reflink tree gets recreated. The customer has verified the
      fix.

      mm: migrate: annotate data-race in migrate_folio_unmap() · 8001070c
      Jeongjun Park authored
      I found a report from syzbot [1]
      
      This report shows that the value can be changed, but in reality, the
      value of __folio_set_movable() cannot be changed because it holds the
      folio refcount.
      
      Therefore, it is appropriate to add an annotate to make KCSAN
      ignore that data-race.

      mm/hugetlb: simplify refs in memfd_alloc_folio · dc677b5f
      Steve Sistare authored
      The folio_try_get in memfd_alloc_folio is not necessary.  Delete it, and
      delete the matching folio_put in memfd_pin_folios.  This also avoids
      leaking a ref if the memfd_alloc_folio call to hugetlb_add_to_page_cache
      fails.  That error path is also broken in a second way -- when its
      folio_put causes the ref to become 0, it will implicitly call
      free_huge_folio, but then the path *explicitly* calls free_huge_folio. 
      Delete the latter.

      If memfd_pin_folios tries to create a hugetlb page, but someone else

      mm/gup: fix memfd_pin_folios hugetlb page allocation · 9289f020
      Steve Sistare authored
      When memfd_pin_folios -> memfd_alloc_folio creates a hugetlb page, the
      index is wrong.  The subsequent call to filemap_get_folios_contig thus
      cannot find it, and fails, and memfd_pin_folios loops forever.  To fix,
      adjust the index for the huge_page_order.
      
      memfd_alloc_folio also forgets to unlock the folio, so the next touch of
      the page calls hugetlb_fault which blocks forever trying to take the lock.
      Unlock it.

      mm/hugetlb: fix memfd_pin_folios resv_huge_pages leak · 26a8ea80
      Steve Sistare authored
      memfd_pin_folios followed by unpin_folios leaves resv_huge_pages elevated
      if the pages were not already faulted in.  During a normal page fault,
      resv_huge_pages is consumed here:
      
      hugetlb_fault()
        alloc_hugetlb_folio()
          dequeue_hugetlb_folio_vma()
            dequeue_hugetlb_folio_nodemask()
              dequeue_hugetlb_folio_node_exact()
                free_huge_pages--
            resv_huge_pages--
      
      During memfd_pin_folios, the page is created by calling
      alloc_hugetlb_folio_nodemask instead of alloc_hugetlb_folio, and
      resv_huge_pages is not modified:
      
      memfd_alloc_folio()
        alloc_hugetlb_folio_nodemask()
          dequeue_hugetlb_folio_nodemask()
            dequeue_hugetlb_folio_node_exact()
              free_huge_pages--
      
      alloc_hugetlb_folio_nodemask has other callers that must not modify
      resv_huge_pages.  Therefore, to fix, define an alternate version of
      alloc_hugetlb_folio_nodemask for this call site that adjusts
      resv_huge_pages.

      Steve Sistare authored
      memfd_pin_folios followed by unpin_folios fails to restore free_huge_pages
      if the pages were not already faulted in, because the folio refcount for
      pages created by memfd_alloc_folio never goes to 0.  memfd_pin_folios
      needs another folio_put to undo the folio_try_get below:
      
      memfd_alloc_folio()
        alloc_hugetlb_folio_nodemask()
          dequeue_hugetlb_folio_nodemask()
            dequeue_hugetlb_folio_node_exact()
              folio_ref_unfreeze(folio, 1);    ; adds 1 refcount
        folio_try_get()                        ; adds 1 refcount
        hugetlb_add_to_page_cache()            ; adds 512 refcount (on x86)
      
      With the fix, after memfd_pin_folios + unpin_folios, the refcount for the
      (unfaulted) page is 512, which is correct, as the refcount for a faulted
      unpinned page is 513.

      mm/filemap: fix filemap_get_folios_contig THP panic · c225c4f6
      Steve Sistare authored
      Patch series "memfd-pin huge page fixes".
      
      Fix multiple bugs that occur when using memfd_pin_folios with hugetlb
      pages and THP.  The hugetlb bugs only bite when the page is not yet
      faulted in when memfd_pin_folios is called.  The THP bug bites when the
      starting offset passed to memfd_pin_folios is not huge page aligned.  See
      the commit messages for details.
      
      
      This patch (of 5):
      
      memfd_pin_folios on memory backed by THP panics if the requested start
      offset is not huge page aligned:
      
      BUG: kernel NULL pointer dereference, address: 0000000000000036
      RIP: 0010:filemap_get_folios_contig+0xdf/0x290
      RSP: 0018:ffffc9002092fbe8 EFLAGS: 00010202
      RAX: 0000000000000002 RBX: 0000000000000002 RCX: 0000000000000002
      
      The fault occurs here, because xas_load returns a folio with value 2:
      
          filemap_get_folios_contig()
              for (folio = xas_load(&xas); folio && xas.xa_index <= end;
                              folio = xas_next(&xas)) {
                      ...
                      if (!folio_try_get(folio))   <-- BOOM
      
      "2" is an xarray sibling entry.  We get it because memfd_pin_folios does
      not round the indices passed to filemap_get_folios_contig to huge page
      boundaries for THP, so we load from the middle of a huge page range see a
      sibling.  (It does round for hugetlbfs, at the is_file_hugepages test).
      
      To fix, if the folio is a sibling, then return the next index as the
      starting point for the next call to filemap_get_folios_contig.

      mm: make SPLIT_PTE_PTLOCKS depend on SMP · a3344078
      Guenter Roeck authored
      SPLIT_PTE_PTLOCKS depends on "NR_CPUS >= 4".  Unfortunately, that
      evaluates to true if there is no NR_CPUS configuration option.  This
      results in CONFIG_SPLIT_PTE_PTLOCKS=y for mac_defconfig.  This in turn
      causes the m68k "q800" and "virt" machines to crash in qemu if debugging
      options are enabled.
      
      Making CONFIG_SPLIT_PTE_PTLOCKS dependent on the existence of NR_CPUS does
      not work since a dependency on the existence of a numeric Kconfig entry
      always evaluates to false.  Example:
      
      config HAVE_NO_NR_CPUS
             def_bool y
             depends on !NR_CPUS
      
      After adding this to a Kconfig file, "make defconfig" includes:
      $ grep NR_CPUS .config
      CONFIG_NR_CPUS=64
      CONFIG_HAVE_NO_NR_CPUS=y
      
      Defining NR_CPUS for m68k does not help either since many architectures
      define NR_CPUS only for SMP configurations.
      
      Make SPLIT_PTE_PTLOCKS depend on SMP instead to solve the problem.

      tools: fix shared radix-tree build · c234c653
      Lorenzo Stoakes authored
      The shared radix-tree build is not correctly recompiling when
      lib/maple_tree.c and lib/test_maple_tree.c are modified - fix this by
      adding these core components to the SHARED_DEPS list.
      
      Additionally, add missing header guards to shared header files.

      This reverts commit fb97d2eb.
      
      The logging was questionable to begin with, but it seems to actively
      deadlock on the task lock.
      
       "On second thought, let's not log core dump failures. 'Tis a silly place"
      
      because if you can't tell your core dump is truncated, maybe you should
      just fix your debugger instead of adding bugs to the kernel.

      Pull HID fix from Jiri Kosina:
       "A revert of Device Tree binding for Goodix SPI HID driver (while
        keeping ACPI still available), as it conflicted with already existing
        binding and the original submitter didn't respond in time with a fix.
      
        We will be looking into ways how to reintroduce it properly (we have
        to agree on a way how to handle cases where vendor uses the very same
        product ID for I2C and SPI parts, leading to this kind conflict). But
        before that is settled, let's revert the to unbreak everybody else
        (Krzysztof Kozlowski)"
