NFS client updates for Linux 6.5
Highlights include:
Stable fixes and other bugfixes:
- nfs: don't report STATX_BTIME in ->getattr
- Revert "NFSv4: Retry LOCK on OLD_STATEID during delegation return"
since it breaks NFSv4 state recovery.
- NFSv4.1: freeze the session table upon receiving NFS4ERR_BADSESSION
- Fix the NFSv4.2 xattr cache shrinker_id
- Force a ctime update after a NFSv4.2 SETXATTR call
Features and cleanups:
- NFS and RPC over TLS client code from Chuck Lever.
- Support for use of abstract unix socket addresses with the rpcbind
daemon.
- Sysfs API to allow shutdown of the kernel RPC client and prevent
umount() hangs if the server is known to be permanently down.
- XDR cleanups from Anna.

A single regression fix for x86:
Moving the invocation of arch_cpu_finalize_init() earlier in the boot process caused a boot regression on IBT enabled system. The root cause is not the move of arch_cpu_finalize_init() itself. The system fails to boot because the subsequent efi_enter_virtual_mode() code has a non-IBT safe EFI call inside. This was never noticed because IBT was enabled after the EFI initialization. Switching the EFI call to use the IBT safe wrapper cures the problem. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmSga0ITHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYofPAEADCjJ40zgv7cbi6VTKudQhASwclWimy zJk1hR6u+Gt7slDAOS/lcHwPzwPB2wn9VsdTHClSHeJbdT3GBKMCOQOFaj1mHvOW e9H7PKUn76OLUSQtpquNiXvnkZGGK/FkTBCi1dEX3xhrWYQ9EVAg/9gDPLtCR5vv cS95KAETGq/7Krxdkgn/w1cav13t+WA25EjAochwG0DAiqVpj+QK1X+dvm8S9F4I MAyLboPK7cN7WijMVxruy1ho+n8L4ZHv6GcOnd9hD/Z6Tyk48hTvQOpVD7V3h1Yc GWzXVyOETuDAwBubfbxCFWQ2nbzwE6uCTGlwyaCmCxixxNSXhyiysvLOLgZr+tD9 97/Z2tZM+nWjnL8vXvpVCKTNJHTssgh2GvUiKzecRuJWK/FoyfbiZllztVPewmRx k9hwf1qMzW8/XpcpfuY9XkfOBIPDUqWpKBtl9XpprU3EFOjEFfkNmdhGPFHkKefG v0LL3dc19f5N8/tFJN5mEww1ZolgQ0aIKqvT0CeY0x0MvCTT214OWb59tzrn+dw3 tth+pGIZnh+5qM8geE1jQ162zkg+r0UaK4TClTqgwzrxIUHmBygI+LVnuPu2iYMi KlJSaOiU60NjzzVVujbSFclPIgkcINuVuQh5zyTGMBLtRgxPzARKTr8v9dqalHeH xcmDJsrKIpMy7A== =T/8G -----END PGP SIGNATURE----- Merge tag 'x86-urgent-2023-07-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fix from Thomas Gleixner: "A single regression fix for x86: Moving the invocation of arch_cpu_finalize_init() earlier in the boot process caused a boot regression on IBT enabled system.

Merge tag 'cxl-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL updates from Dan Williams:
"The highlights in terms of new functionality are support for the
standard CXL Performance Monitor definition that appeared in CXL 3.0,
support for device sanitization (wiping all data from a device),
secure-erase (re-keying encryption of user data), and support for
firmware update. The firmware update support is notable as it reuses
the simple sysfs_upload interface to just cat(1) a blob to a sysfs
file and pipe that to the device.
Additionally there are a substantial number of cleanups and
reorganizations to get ready for RCH error handling (RCH == Restricted
CXL Host == current shipping hardware generation / pre CXL-2.0
topologies) and type-2 (accelerator / vendor specific) devices.
For vendor specific devices they implement a subset of what the
generic type-3 (generic memory expander) driver expects. As a result
the rework decouples optional infrastructure from the core driver
context.
For RCH topologies, where the specification working group did not want
to confuse pre-CXL-aware operating systems, many of the standard
registers are hidden which makes support standard bus features like
AER (PCIe Advanced Error Reporting) difficult. The rework arranges for
the driver to help the PCI-AER core. Bjorn is on board with this
direction but a late regression disocvery means the completion of this
functionality needs to cook a bit longer, so it is code
reorganizations only for now.
Summary:
- Add infrastructure for supporting background commands along with
support for device sanitization and firmware update
- Introduce a CXL performance monitoring unit driver based on the
common definition in the specification.
- Land some preparatory cleanup and refactoring for the anticipated
arrival of CXL type-2 (accelerator devices) and CXL RCH (CXL-v1.1

flexible-array transformations for 6.5-rc1
Hi Linus, Please, pull the following patch that transforms a zero-length array into a C99 flexible-array member. This patch has been baking in linux-next for a while.

mm: Update do_vmi_align_munmap() return semantics
Since do_vmi_align_munmap() will always honor the downgrade request on the success, the callers no longer have to deal with confusing return codes. Since all callers that request downgrade actually want the lock to be dropped, change the downgrade to an unlock request. Note that the lock still needs to be held in read mode during the page table clean up to avoid races with a map request. Update do_vmi_align_munmap() to return 0 for success. Clean up the callers and comments to always expect the unlock to be honored on the success path. The error path will always leave the lock untouched. As part of the cleanup, the wrapper function do_vmi_munmap() and callers to the wrapper are also updated.

mm: Always downgrade mmap_lock if requested
Now that stack growth must always hold the mmap_lock for write, we can always downgrade the mmap_lock to read and safely unmap pages from the page table, even if we're next to a stack.

xtensa: fix lock_mm_and_find_vma in case VMA not found
MMU version of lock_mm_and_find_vma releases the mm lock before
returning when VMA is not found. Do the same in noMMU version.

xtensa: fix NOMMU build with lock_mm_and_find_vma() conversion
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.

Merge tag 'pci-v6.5-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
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"

perf tools changes and fixes for v6.5: 1st batch
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 --\

Probes updates for v6.5:
- 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 (except for 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.

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. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZJy6ixQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qnzRAPsEI2YgjaJSHnuPoGRHbrNil6pq66wY LYaLizGI4Jv9BwEAqdSdcYcMiWo1SFBAO8QxEDM++BX3zrRyVgW8ahaTNgs= =TF0C -----END PGP SIGNATURE----- Merge tag 'trace-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing updates from Steven Rostedt: - Add new feature to have function graph tracer record the return value.

pid: Replace struct pid 1-element array with flex-array
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: https://lore.kernel.org/lkml/20230517-bushaltestelle-super-e223978c1ba6@brauner Cc: Christian Brauner <brauner@kernel.org> Cc: Jan Kara <jack@suse.cz> Cc: Jeff Xu <jeffxu@google.com> Cc: Andreas Gruenbacher <agruenba@redhat.com> Cc: Daniel Verkamp <dverkamp@chromium.org> Cc: "Paul E.

csky: fix up lock_mm_and_find_vma() conversion
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.
Fixes:

tracing: Fix user event write on buffer disabled
The user events write currently returns the size of what was suppose to be written when tracing is disabled and nothing was written. 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. This also includes test cases for this use case -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZJxLzRQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qs9eAP0ZRDempFNyMhi+pfENtwv65CHxRX/3 3s1Lmt04oqwXfgD/dCfojrVAd++kpq3p9cGxJYWuNiM4s47mlD8VLgQ7AAY= =aZ8/ -----END PGP SIGNATURE----- Merge tag 'trace-v6.4-rc7-v3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fix from Steven Rostedt: "Fix user event write on buffer disabled.

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) Link: https://lwn.net/Articles/932201/ [1] * tag 'slab-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab: mm/slab_common: use SLAB_NO_MERGE instead of negative refcount mm/slab: break up RCU readers on SLAB_TYPESAFE_BY_RCU example code mm/slab: add a missing semicolon on SLAB_TYPESAFE_BY_RCU example code mm/slab_common: reduce an if statement in create_cache() mm/slab: introduce kmem_cache flag SLAB_NO_MERGE mm/slab: rename CONFIG_SLAB to CONFIG_SLAB_DEPRECATED mm/slab: remove HAVE_HARDENED_USERCOPY_ALLOCATOR mm/slab_common: Replace invocation of weak PRNG mm/slab: Replace invocation of weak PRNG slub: Don't read nr_slabs and total_objects directly slub: Remove slabs_node() function slub: Remove CONFIG_SMP defined check slub: Put objects_show() into CONFIG_SLUB_DEBUG enabled block slub: Correct the error code when slab_kset is NULL mm/slab: correct return values in comment for _kmem_cache_create() |
