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"

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

Previous patch modified the standard used by acpi_gpiochip_find()
to match device nodes. Using the device node set in gc->gpiodev->d-
ev instead of gc->parent.

However, there is a situation in gpio-dwapb where the GPIO device
driver will set gc->fwnode for each port corresponding to a child
node under a GPIO device, so gc->gpiodev->dev will be assigned the
value of each child node in gpiochip_add_data().

gpio-dwapb.c:
128,31 static int dwapb_gpio_add_port(struct dwapb_gpio *gpio,
			       struct dwapb_port_property *pp,
			       unsigned int offs);
port->gc.fwnode = pp->fwnode;

693,39 static int dwapb_gpio_probe;
err = dwapb_gpio_add_port(gpio, &pdata->properties[i], i);

When other drivers request GPIO pin resources through the GPIO device
node provided by ACPI (corresponding to the parent node), the change
of the matching object to gc->gpiodev->dev in acpi_gpiochip_find()
only allows finding the value of each port (child node), resulting
in a failed request.

Reapply the condition of using gc->parent for match in acpi_gpio-
chip_find() in the code can compatible with the problem of gpio-dwapb,
and will not affect the two cases mentioned in the patch:
1. There is no setting for gc->fwnode.
2. The case that depends on using gc->fwnode for match.

pidfs started using much saner inodes in commit b28ddcc3 ("pidfs:
convert to path_from_stashed() helper"), but that exposed the fact that
lsof had some knowledge of just how odd our old anon_inode usage was.

For example, legacy anon_inodes hadn't even initialized the inode type
in the inode mode, so everything had a type of zero.

So sane tools like 'stat' would report these files as "weird file", but
'lsof' instead used that (together with the name of the link in proc) to
notice that it's an anonymous inode, and used it to detect pidfd files.

Let's keep our internal new sane inode model, but mask the file type
bits at 'stat()' time in the getattr() function we already have, and by
making the dentry name match what lsof expects too.

This keeps our internal models sane, but should make user space see the
same old odd behavior.

When asn1_encode_sequence() fails, WARN is not the correct solution.

1. asn1_encode_sequence() is not an internal function (located
   in lib/asn1_encode.c).
2. Location is known, which makes the stack trace useless.
3. Results a crash if panic_on_warn is set.

It is also noteworthy that the use of WARN is undocumented, and it
should be avoided unless there is a carefully considered rationale to
use it.

Replace WARN with pr_err, and print the return value instead, which is
only useful piece of information.

Pull f2fs updates from Jaegeuk Kim:
 "In this round, we've tried to address some performance issues on zoned
  storage such as direct IO and write_hints. In addition, we've migrated
  some IO paths using folio. Meanwhile, there are multiple bug fixes in
  the compression paths, sanity check conditions, and error handlers.

  Enhancements:
   - allow direct io of pinned files for zoned storage
   - assign the write hint per stream by default
   - convert read paths and test_writeback to folio
   - avoid allocating WARM_DATA segment for direct IO

  Bug fixes:
   - fix false alarm on invalid block address
   - fix to add missing iput() in gc_data_segment()
   - fix to release node block count in error path of
     f2fs_new_node_page()
   - compress:
       - don't allow unaligned truncation on released compress inode
       - cover {reserve,release}_compress_blocks() w/ cp_rwsem lock
       - fix error path of inc_valid_block_count()
       - fix to update i_compr_blocks correctly
   - fix block migration when section is not aligned to pow2
   - don't trigger OPU on pinfile for direct IO
   - fix to do sanity check on i_xattr_nid in sanity_check_inode()
   - write missing last sum blk of file pinning section
   - clear writeback when compression failed
   - fix to adjust appropirate defragment pg_end

  As usual, there are several minor code clean-ups, and fixes to manage
  missing corner cases in the error paths"

Pull xfs updates from Chandan Babu:
 "Online repair feature continues to be expanded. Also, we now support
  delayed allocation for realtime devices which have an extent size that
  is equal to filesystem's block size.

  New code:

   - Introduce Parent Pointer extended attribute for inodes

   - Bring back delalloc support for realtime devices which have an
     extent size that is equal to filesystem's block size

   - Improve performance of log incompat feature handling

  Online Repair:

   - Implement atomic file content exchanges i.e. exchange ranges of
     bytes between two files atomically

   - Create temporary files to repair file-based metadata. This uses
     atomic file content exchange facility to swap file fork mappings
     between the temporary file and the metadata inode

   - Allow callers of directory/xattr code to set an explicit owner
     number to be written into the header fields of any new blocks that
     are created. This is required to avoid walking every block of the
     new structure and modify their ownership during online repair

   - Repair more data structures:
       - Extended attributes
       - Inode unlinked state
       - Directories
       - Symbolic links
       - AGI's unlinked inode list
       - Parent pointers

   - Move Orphan files to lost and found directory

   - Fixes for Inode repair functionality

   - Introduce a new sub-AG FITRIM implementation to reduce the duration
     for which the AGF lock is held

   - Updates for the design documentation

   - Use Parent Pointers to assist in checking directories, parent
     pointers, extended attributes, and link counts

  Fixes:

   - Prevent userspace from reading invalid file data due to incorrect.
     updation of file size when performing a non-atomic clone operation

   - Minor fixes to online repair

   - Fix confusing return values from xfs_bmapi_write()

   - Fix an out of bounds access due to incorrect h_size during log
     recovery

   - Defer upgrading the extent counters in xfs_reflink_end_cow_extent()
     until we know we are going to modify the extent mapping

   - Remove racy access to if_bytes check in
     xfs_reflink_end_cow_extent()

   - Fix sparse warnings

  Cleanups:

   - Hold inode locks on all files involved in a rename until the
     completion of the operation. This is in preparation for the parent
     pointers patchset where parent pointers are applied in a separate
     chained update from the actual directory update

   - Compile out v4 support when disabled

   - Cleanup xfs_extent_busy_clear()

   - Remove unused flags and fields from struct xfs_da_args

   - Remove definitions of unused functions

   - Improve extended attribute validation

   - Add higher level directory operations helpers to remove duplication
     of code

   - Cleanup quota (un)reservation interfaces"

Commit 4f563a64 ("block: add a max_user_discard_sectors queue
limit") changed block core to set max_discard_sectors to:
 min(lim->max_hw_discard_sectors, lim->max_user_discard_sectors)

Since commit 1c0e7202 ("dm: use queue_limits_set") it was reported
dm-thinp was failing in a few fstests (generic/347 and generic/405)
with the first WARN_ON_ONCE in dm_cell_key_has_valid_range() being
reported, e.g.:
WARNING: CPU: 1 PID: 30 at drivers/md/dm-bio-prison-v1.c:128 dm_cell_key_has_valid_range+0x3d/0x50

blk_set_stacking_limits() sets max_user_discard_sectors to UINT_MAX,
so given how block core now sets max_discard_sectors (detailed above)
it follows that blk_stack_limits() stacks up the underlying device's
max_hw_discard_sectors and max_discard_sectors is set to match it. If
max_hw_discard_sectors exceeds dm's BIO_PRISON_MAX_RANGE, then
dm_cell_key_has_valid_range() will trigger the warning with:
WARN_ON_ONCE(key->block_end - key->block_begin > BIO_PRISON_MAX_RANGE)

Aside from this warning, the discard will fail.  Fix this and other DM
issues by governing discard support in terms of max_hw_discard_sectors
instead of max_discard_sectors.

dm-integrity could set discard_granularity lower than the logical block
size. This could result in failures when sending discard requests to
dm-integrity.

This fix is needed for kernels prior to 6.10.
