We switch session state to SES_EXITING without cifs_tcp_ses_lock now,
it may lead to potential use-after-free issue.

Consider the following execution processes:

Thread 1:
__cifs_put_smb_ses()
    spin_lock(&cifs_tcp_ses_lock)
    if (--ses->ses_count > 0)
        spin_unlock(&cifs_tcp_ses_lock)
        return
    spin_unlock(&cifs_tcp_ses_lock)
        ---> **GAP**
    spin_lock(&ses->ses_lock)
    if (ses->ses_status == SES_GOOD)
        ses->ses_status = SES_EXITING
    spin_unlock(&ses->ses_lock)

Thread 2:
cifs_find_smb_ses()
    spin_lock(&cifs_tcp_ses_lock)
    list_for_each_entry(ses, ...)
        spin_lock(&ses->ses_lock)
        if (ses->ses_status == SES_EXITING)
            spin_unlock(&ses->ses_lock)
            continue
        ...
        spin_unlock(&ses->ses_lock)
    if (ret)
        cifs_smb_ses_inc_refcount(ret)
    spin_unlock(&cifs_tcp_ses_lock)

If thread 1 is preempted in the gap and thread 2 start executing, thread 2
will get the session, and soon thread 1 will switch the session state to
SES_EXITING and start releasing it, even though thread 1 had increased the
session's refcount and still uses it.

So switch session state under cifs_tcp_ses_lock to eliminate this gap.

It turns out that xtensa has a really odd configuration situation: you
can do a no-MMU config, but still have the page fault code enabled.
Which doesn't sound all that sensible, but it turns out that xtensa can
have protection faults even without the MMU, and we have this:

    config PFAULT
        bool "Handle protection faults" if EXPERT && !MMU
        default y
        help
          Handle protection faults. MMU configurations must enable it.
          noMMU configurations may disable it if used memory map never
          generates protection faults or faults are always fatal.

          If unsure, say Y.

which completely violated my expectations of the page fault handling.

End result: Guenter reports that the xtensa no-MMU builds all fail with

  arch/xtensa/mm/fault.c: In function ‘do_page_fault’:
  arch/xtensa/mm/fault.c:133:8: error: implicit declaration of function ‘lock_mm_and_find_vma’

because I never exposed the new lock_mm_and_find_vma() function for the
no-MMU case.

Doing so is simple enough, and fixes the problem.

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Export pcie_retrain_link() for use outside ASPM

   - Add Data Link Layer Link Active Reporting as another way for
     pcie_retrain_link() to determine the link is up

   - Work around link training failures (especially on the ASMedia
     ASM2824 switch) by training first at 2.5GT/s and then attempting
     higher rates

  Resource management:

   - When we coalesce host bridge windows, remove invalidated resources
     from the resource tree so future allocations work correctly

  Hotplug:

   - Cancel bringup sequence if card is not present, to keep from
     blinking Power Indicator indefinitely

   - Reassign bridge resources if necessary for ACPI hotplug

  Driver binding:

   - Convert platform_device .remove() callbacks to return void instead
     of a mostly useless int

  Power management:

   - Reduce wait time for secondary bus to be ready to speed up resume

   - Avoid putting EloPOS E2/S2/H2 (as well as Elo i2) PCIe Ports in
     D3cold

   - Call _REG when transitioning D-states so AML that uses the PCI
     config space OpRegion works, which fixes some ASMedia GPIO
     controllers after resume

  Virtualization:

   - Delay extra 250ms after FLR of Solidigm P44 Pro NVMe to avoid KVM
     hang when guest is rebooted

   - Add function 1 DMA alias quirk for Marvell 88SE9235

  Error handling:

   - Unexport pci_save_aer_state() since it's only used in drivers/pci/

   - Drop recommendation for drivers to configure AER Capability, since
     the PCI core does this for all devices

  ASPM:

   - Disable ASPM on MFD function removal to avoid use-after-free

   - Tighten up pci_enable_link_state() and pci_disable_link_state()
     interfaces so they don't enable/disable states the driver didn't
     specify

   - Avoid link retraining race that can happen if ASPM sets link
     control parameters while the link is in the midst of training for
     some other reason

  Endpoint framework:

   - Change "PCI Endpoint Virtual NTB driver" Kconfig prompt to be
     different from "PCI Endpoint NTB driver"

   - Automatically create a function specific attributes group for
     endpoint drivers to avoid reference counting issues

   - Fix many EPC test issues

   - Return pci_epf_type_add_cfs() error if EPF has no driver

   - Add kernel-doc for pci_epc_raise_irq() and pci_epc_map_msi_irq()
     MSI vector parameters

   - Pass EPF device ID to driver probe functions

   - Return -EALREADY if EPC has already been started/stopped

   - Add linkdown notifier support and use it in qcom-ep

   - Add Bus Master Enable event support and use it in qcom-ep

   - Add Qualcomm Modem Host Interface (MHI) endpoint driver

   - Add Layerscape PME interrupt handling to manage link-up
     notification

  Cadence PCIe controller driver:

   - Wait for link retrain to complete when working around the J721E
     i2085 erratum with Gen2 mode

  Faraday FTPC100 PCI controller driver:

   - Release clock resources on error paths

  Freescale i.MX6 PCIe controller driver:

   - Save and restore Root Port MSI control to work around hardware defect

  Intel VMD host bridge driver:

   - Reset VMD config register between soft reboots

   - Capture pci_reset_bus() return value instead of printing junk when
     it fails

  Qualcomm PCIe controller driver:

   - Add SDX65 endpoint compatible string to DT binding

   - Disable register write access after init for IP v2.3.3, v2.9.0

   - Use DWC helpers for enabling/disabling writes to DBI registers

   - Hide slot hotplug capability for IP v1.0.0, v1.9.0, v2.1.0, v2.3.2,
     v2.3.3, v2.7.0, v2.9.0

   - Reuse v2.3.2 post-init sequence for v2.4.0

  Renesas R-Car PCIe controller driver:

   - Remove unused static pcie_base and pcie_dev

  Rockchip PCIe controller driver:

   - Remove writes to unused registers

   - Write endpoint Device ID using correct register

   - Assert PCI Configuration Enable bit after probe so endpoint
     responds instead of generating Request Retry Status messages

   - Poll waiting for PHY PLLs to lock

   - Update RK3399 example DT binding to be valid

   - Use RK3399 PCIE_CLIENT_LEGACY_INT_CTRL to generate INTx instead of
     manually generating PCIe message

   - Use multiple windows to avoid address translation conflicts

   - Use u32 (not u16) when accessing 32-bit registers

   - Hide MSI-X Capability, since RK3399 can't generate MSI-X

   - Set endpoint controller required alignment to 256

  Synopsys DesignWare PCIe controller driver:

   - Wait for link to come up only if we've initiated link training

  Miscellaneous:

   - Add pci_clear_master() stub for non-CONFIG_PCI"

Pull perf tools updates from Namhyung Kim:
 "Internal cleanup:

   - Refactor PMU data management to handle hybrid systems in a generic
     way.

     Do more work in the lexer so that legacy event types parse more
     easily. A side-effect of this is that if a PMU is specified,
     scanning sysfs is avoided improving start-up time.

   - Fix hybrid metrics, for example, the TopdownL1 works for both
     performance and efficiency cores on Intel machines. To support
     this, sort and regroup events after parsing.

   - Add reference count checking for the 'thread' data structure.

   - Lots of fixes for memory leaks in various places thanks to the ASAN
     and Ian's refcount checker.

   - Reduce the binary size by replacing static variables with local or
     dynamically allocated memory.

   - Introduce shared_mutex for annotate data to reduce memory
     footprint.

   - Make filesystem access library functions more thread safe.

  Test:

   - Organize cpu_map tests into a single suite.

   - Add metric value validation test to check if the values are within
     correct value ranges.

   - Add perf stat stdio output test to check if event and metric names
     match.

   - Add perf data converter JSON output test.

   - Fix a lot of issues reported by shellcheck(1). This is a
     preparation to enable shellcheck by default.

   - Make the large x86 new instructions test optional at build time
     using EXTRA_TESTS=1.

   - Add a test for libpfm4 events.

  perf script:

   - Add 'dsoff' outpuf field to display offset from the DSO.

      $ perf script -F comm,pid,event,ip,dsoff
         ls 2695501 cycles:      152cc73ef4b5 (/usr/lib/x86_64-linux-gnu/ld-2.31.so+0x1c4b5)

         ls 2695501 cycles:  ffffffff992a6db0 ([kernel.kallsyms])

   - Adjust width for large PID/TID values.

  perf report:

   - Robustify reading addr2line output for srcline by checking sentinel
     output before the actual data and by using timeout of 1 second.

   - Allow config terms (like 'name=ABC') with breakpoint events.

      $ perf record -e mem:0x55feb98dd169:x/name=breakpoint/ -p 19646 -- sleep 1

  perf annotate:

   - Handle x86 instruction suffix like 'l' in 'movl' generally.

   - Parse instruction operands properly even with a whitespace. This is
     needed for llvm-objdump output.

   - Support RISC-V binutils lookup using the triplet prefixes.

   - Add '<' and '>' key to navigate to prev/next symbols in TUI.

   - Fix instruction association and parsing for LoongArch.

  perf stat:

   - Add --per-cache aggregation option, optionally specify a cache
     level like `--per-cache=L2`.

      $ sudo perf stat --per-cache -a -e ls_dmnd_fills_from_sys.ext_cache_remote --\
        taskset -c 0-15,64-79,128-143,192-207\

   - Allow --cputype option to have any PMU name (not just hybrid).

   - Fix output value not to added when it runs multiple times with -r
     option.

  perf list:

   - Show metricgroup description from JSON file called
     metricgroups.json.

   - Allow 'pfm' argument to list only libpfm4 events and check each
     event is supported before showing it.

  JSON vendor events:

   - Avoid event grouping using "NO_GROUP_EVENTS" constraints. The
     topdown events are correctly grouped even if no group exists.

   - Add "Default" metric group to print it in the default output. And
     use "DefaultMetricgroupName" to indicate the real metric group
     name.

   - Add AmpereOne core PMU events.

  Misc:

   - Define man page date correctly.

   - Track exception level properly on ARM CoreSight ETM.

   - Allow anonymous struct, union or enum when retrieving type names
     from DWARF.

   - Fix incorrect filename when calling `perf inject --jit`.

   - Handle PLT size correctly on LoongArch"

Pull probes updates from Masami Hiramatsu:

 - fprobe: Pass return address to the fprobe entry/exit callbacks so
   that the callbacks don't need to analyze pt_regs/stack to find the
   function return address.

 - kprobe events: cleanup usage of TPARG_FL_FENTRY and TPARG_FL_RETURN
   flags so that those are not set at once.

 - fprobe events:
      - Add a new fprobe events for tracing arbitrary function entry and
        exit as a trace event.
      - Add a new tracepoint events for tracing raw tracepoint as a
        trace event. This allows user to trace non user-exposed
        tracepoints.
      - Move eprobe's event parser code into probe event common file.
      - Introduce BTF (BPF type format) support to kernel probe (kprobe,
        fprobe and tracepoint probe) events so that user can specify
        traced function arguments by name. This also applies the type of
        argument when fetching the argument.
      - Introduce '$arg*' wildcard support if BTF is available. This
        expands the '$arg*' meta argument to all function argument
        automatically.
      - Check the return value types by BTF. If the function returns
        'void', '$retval' is rejected.
      - Add some selftest script for fprobe events, tracepoint events
        and BTF support.
      - Update documentation about the fprobe events.
      - Some fixes for above features, document and selftests.

 - selftests for ftrace (in addition to the new fprobe events):
      - Add a test case for multiple consecutive probes in a function
        which checks if ftrace based kprobe, optimized kprobe and normal
        kprobe can be defined in the same target function.
      - Add a test case for optimized probe, which checks whether kprobe
        can be optimized or not.

Pull tracing updates from Steven Rostedt:

 - Add new feature to have function graph tracer record the return
   value. Adds a new option: funcgraph-retval ; when set, will show the
   return value of a function in the function graph tracer.

 - Also add the option: funcgraph-retval-hex where if it is not set, and
   the return value is an error code, then it will return the decimal of
   the error code, otherwise it still reports the hex value.

 - Add the file /sys/kernel/tracing/osnoise/per_cpu/cpu<cpu>/timerlat_fd
   That when a application opens it, it becomes the task that the timer
   lat tracer traces. The application can also read this file to find
   out how it's being interrupted.

 - Add the file /sys/kernel/tracing/available_filter_functions_addrs
   that works just the same as available_filter_functions but also shows
   the addresses of the functions like kallsyms, except that it gives
   the address of where the fentry/mcount jump/nop is. This is used by
   BPF to make it easier to attach BPF programs to ftrace hooks.

 - Replace strlcpy with strscpy in the tracing boot code.

For pid namespaces, struct pid uses a dynamically sized array member,
"numbers".  This was implemented using the ancient 1-element fake
flexible array, which has been deprecated for decades.

Replace it with a C99 flexible array, refactor the array size
calculations to use struct_size(), and address elements via indexes.
Note that the static initializer (which defines a single element) works
as-is, and requires no special handling.

Without this, CONFIG_UBSAN_BOUNDS (and potentially
CONFIG_FORTIFY_SOURCE) will trigger bounds checks:

As already mentioned in my merge message for the 'expand-stack' branch,
we have something like 24 different versions of the page fault path for
all our different architectures, all just _slightly_ different due to
various historical reasons (usually related to exactly when they
branched off the original i386 version, and the details of the other
architectures they had in their history).

And a few of them had some silly mistake in the conversion.

Most of the architectures call the faulting address 'address' in the
fault path.  But not all.  Some just call it 'addr'.  And if you end up
doing a bit too much copy-and-paste, you end up with the wrong version
in the places that do it differently.

In this case it was csky.

In commit 8d7071af ("mm: always expand the stack with the mmap write
lock held") I tried to deal with the remaining odd page fault handling
cases.  The oddest one is ia64, which has stacks that grow both up and
down.  And because ia64 was _so_ odd, I asked people to verify the end
result.

But a close second oddity is parisc, which is the only one that has a
main stack growing up (our "CONFIG_STACK_GROWSUP" config option).  But
it looked obvious enough that I didn't worry about it.

I should have worried a bit more.  Not because it was particularly
complex, but because I just used the wrong variable name.

The previous vma isn't called "prev", it's called "prev_vma".  Blush.

The sparc32 conversion to lock_mm_and_find_vma() in commit a050ba1e


("mm/fault: convert remaining simple cases to lock_mm_and_find_vma()")
missed the fact that we didn't actually have a 'regs' pointer available
in the 'force_user_fault()' case.

It's there in the regular page fault path ("do_sparc_fault()"), but not
the window underflow/overflow paths.

Which is all fine - we can just pass in a NULL pointer.  The register
state is only used to avoid deadlock with kernel faults, which is not
the case for any of these register window faults.

  The user events write currently returns the size of what was supposed

  Instead, behave like trace_marker and return -EBADF, as that is what
  is returned if a file is opened for read only, and a write is
  performed on it. Writing to the buffer that is disabled is like trying
  to write to a file opened for read only, as the buffer still can be
  read, but just not written to.

The objtool merge in commit 6f612579 ("Merge tag 'objtool-core ...")
generated a semantic conflict that was not resolved.

The btrfs_assertfail() entry was removed from the noreturn list in
commit b831306b ("btrfs: print assertion failure report and stack
trace from the same line") because btrfs_assertfail() was changed from a
noreturn function into a macro.

The noreturn list was then moved from check.c to noreturns.h in commit
6245ce4a

 ("objtool: Move noreturn function list to separate file"),
and should be removed from that post-merge as well.

Do it explicitly.

Pull slab updates from Vlastimil Babka:

 - SLAB deprecation:

   Following the discussion at LSF/MM 2023 [1] and no objections, the
   SLAB allocator is deprecated by renaming the config option (to make
   its users notice) to CONFIG_SLAB_DEPRECATED with updated help text.
   SLUB should be used instead. Existing defconfigs with CONFIG_SLAB are
   also updated.

 - SLAB_NO_MERGE kmem_cache flag (Jesper Dangaard Brouer):

   There are (very limited) cases where kmem_cache merging is
   undesirable, and existing ways to prevent it are hacky. Introduce a
   new flag to do that cleanly and convert the existing hacky users.
   Btrfs plans to use this for debug kernel builds (that use case is
   always fine), networking for performance reasons (that should be very
   rare).

 - Replace the usage of weak PRNGs (David Keisar Schmidt):

   In addition to using stronger RNGs for the security related features,
   the code is a bit cleaner.

 - Misc code cleanups (SeongJae Parki, Xiongwei Song, Zhen Lei, and
   zhaoxinchao)
