smb3: fix perf regression with cached writes with netfs conversion
Write through mode is for cache=none, not for default (when
caching is allowed if we have a lease). Some tests were running
much, much more slowly as a result of disabling caching of
writes by default.

smb: smb2pdu.h: Avoid -Wflex-array-member-not-at-end warnings
-Wflex-array-member-not-at-end is coming in GCC-14, and we are getting ready to enable it globally. So, in order to avoid ending up with a flexible-array member in the middle of multiple other structs, we use the `__struct_group()` helper to separate the flexible array from the rest of the members in the flexible structure, and use the tagged `struct create_context_hdr` instead of `struct create_context`. So, with these changes, fix 51 of the following warnings[1]: fs/smb/client/../common/smb2pdu.h:1225:31: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Link: https://gist.github.com/GustavoARSilva/772526a39be3dd4db39e71497f0a9893 [1] Link: https://github.com/KSPP/linux/issues/202 Signed-off-by: Gustavo A.

Merge tag 'vfs-6.10.netfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull netfs updates from Christian Brauner:
"This reworks the netfslib writeback implementation so that pages read
from the cache are written to the cache through ->writepages(),
thereby allowing the fscache page flag to be retired.
The reworking also:
- builds on top of the new writeback_iter() infrastructure
- makes it possible to use vectored write RPCs as discontiguous
streams of pages can be accommodated
- makes it easier to do simultaneous content crypto and stream
division
- provides support for retrying writes and re-dividing a stream
- replaces the ->launder_folio() op, so that ->writepages() is used
instead
- uses mempools to allocate the netfs_io_request and
netfs_io_subrequest structs to avoid allocation failure in the
writeback path
Some code that uses the fscache page flag is retained for
compatibility purposes with nfs and ceph. The code is switched to
using the synonymous private_2 label instead and marked with
deprecation comments.
The merge commit contains additional details on the new algorithm that
I've left out of here as it would probably be excessively detailed.
On top of the netfslib infrastructure this contains the work to
convert cifs over to netfslib"

Features:
- Free up FMODE_* bits. I've freed up bits 6, 7, 8, and 24. That
means we now have six free FMODE_* bits in total (but bit #6
already got used for FMODE_WRITE_RESTRICTED)
- Add FOP_HUGE_PAGES flag (follow-up to FMODE_* cleanup)
- Add fd_raw cleanup class so we can make use of automatic cleanup
provided by CLASS(fd_raw, f)(fd) for O_PATH fds as well
- Optimize seq_puts()
- Simplify __seq_puts()
- Add new anon_inode_getfile_fmode() api to allow specifying f_mode
instead of open-coding it in multiple places
- Annotate struct file_handle with __counted_by() and use
struct_size()
- Warn in get_file() whether f_count resurrection from zero is
attempted (epoll/drm discussion)
- Folio-sophize aio
- Export the subvolume id in statx() for both btrfs and bcachefs
- Relax linkat(AT_EMPTY_PATH) requirements
- Add F_DUPFD_QUERY fcntl() allowing to compare two file descriptors
for dup*() equality replacing kcmp()
Cleanups:
- Compile out swapfile inode checks when swap isn't enabled
- Use (1 << n) notation for FMODE_* bitshifts for clarity
- Remove redundant variable assignment in fs/direct-io
- Cleanup uses of strncpy in orangefs
- Speed up and cleanup writeback
- Move fsparam_string_empty() helper into header since it's currently
open-coded in multiple places
- Add kernel-doc comments to proc_create_net_data_write()
- Don't needlessly read dentry->d_flags twice
Fixes:
- Fix out-of-range warning in nilfs2
- Fix ecryptfs overflow due to wrong encryption packet size
calculation
- Fix overly long line in xfs file_operations (follow-up to FMODE_*
cleanup)
- Don't raise FOP_BUFFER_{R,W}ASYNC for directories in xfs (follow-up

Merge tag 'slab-for-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull slab updates from Vlastimil Babka:
"This time it's mostly random cleanups and fixes, with two performance
fixes that might have significant impact, but limited to systems
experiencing particular bad corner case scenarios rather than general
performance improvements.
The memcg hook changes are going through the mm tree due to
dependencies.
- Prevent stalls when reading /proc/slabinfo (Jianfeng Wang)
This fixes the long-standing problem that can happen with workloads
that have alloc/free patterns resulting in many partially used
slabs (in e.g. dentry cache). Reading /proc/slabinfo will traverse
the long partial slab list under spinlock with disabled irqs and
thus can stall other processes or even trigger the lockup
detection. The traversal is only done to count free objects so that
<active_objs> column can be reported along with <num_objs>.
To avoid affecting fast paths with another shared counter
(attempted in the past) or complex partial list traversal schemes
that allow rescheduling, the chosen solution resorts to
approximation - when the partial list is over 10000 slabs long, we
will only traverse first 5000 slabs from head and tail each and use
the average of those to estimate the whole list. Both head and tail
are used as the slabs near head to tend to have more free objects
than the slabs towards the tail.
It is expected the approximation should not break existing
/proc/slabinfo consumers. The <num_objs> field is still accurate
and reflects the overall kmem_cache footprint. The <active_objs>
was already imprecise due to cpu and percpu-partial slabs, so can't
be relied upon to determine exact cache usage. The difference
between <active_objs> and <num_objs> is mainly useful to determine
the slab fragmentation, and that will be possible even with the
approximation in place.
- Prevent allocating many slabs when a NUMA node is full (Chen Jun)
Currently, on NUMA systems with a node under significantly bigger
pressure than other nodes, the fallback strategy may result in each
kmalloc_node() that can't be safisfied from the preferred node, to
allocate a new slab on a fallback node, and not reuse the slabs
already on that node's partial list.
This is now fixed and partial lists of fallback nodes are checked
even for kmalloc_node() allocations. It's still preferred to
allocate a new slab on the requested node before a fallback, but
only with a GFP_NOWAIT attempt, which will fail quickly when the
node is under a significant memory pressure.
- More SLAB removal related cleanups (Xiu Jianfeng, Hyunmin Lee)
- Fix slub_kunit self-test with hardened freelists (Guenter Roeck)
- Mark racy accesses for KCSAN (linke li)
- Misc cleanups (Xiongwei Song, Haifeng Xu, Sangyun Kim)"

kcsan: Introduce __data_racy type qualifier
This commit adds a __data_racy type qualifier that enables kernel developers to inform KCSAN that a given variable is a shared variable without needing to mark each and every access. This allows pre-KCSAN code to be correctly (if approximately) instrumented withh very little effort, and also provides people reading the code a clear indication that the variable is in fact shared. In addition, it permits incremental transition to per-access KCSAN marking, so that (for example) a given subsystem can be transitioned one variable at a time, while avoiding large numbers of KCSAN warnings during this transition. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEbK7UrM+RBIrCoViJnr8S83LZ+4wFAmY+i+cTHHBhdWxtY2tA a2VybmVsLm9yZwAKCRCevxLzctn7jJQ1D/9eOBNKefU7duZgAOzUizPdxRvxKzPx UENz6DU/xXB+jcaWiRvdWyFgIFnUS/TaZcwtthXh4bV1I754dRFy8X9+/uHd8AVY MUwRkhY3Nie/MgkvLrEmMsfWn9zSUp0Pwq4dwFdhvb0aosFSn7PgtSrE62+RafpZ k1abEUa62MfSLJjJ7C8ThYk9broAgz37drloAStAr4PvrCM4JaoeChkStaAK80z1 qq3EblLtXlzKcW1UNkvsbTxcnv+quLsI4EHKSnN3O8l47/F/k52ENz5Qp1pYTOLk kO3IZjqFqnIH6Re5eHPA05cwQssJFvsB8gfB+g+kc2uOK/z7wwg0/gqf9SZyaosw ABoaxflfNE/mTzKVgob3wqGyhlsAE/R2k02yoMad4X78ATOi9RpjdH6xC4OOXYfV 4P8g2hGAHNR8UgYosXFx+YCu2ktGYyfsqTicMaaaECUfxFeJjJ1QqgwHYHADDDv/ x8UxggAco1jul+6fikPGnjDgBN5IJOwS26NEUguqAFqYMTF8OO/x6ag6cqG5nk3a b41GF4HEfoQtJduuOv8jVntyTRU7zbpH+AVuinQ1V34kpYp5fE75p30P4UUjMegA JaAoOeD9aebEUHHlujomaV/QKSHobYLmYp/ARe2QZjp7aiELcjvV/ThOdwRxGEZg Zl4qRaGc9YO/Ag== =f1gr -----END PGP SIGNATURE----- Merge tag 'kcsan.2024.05.10a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull kcsan update from Paul McKenney: "Introduce __data_racy type qualifier This adds a __data_racy type qualifier that enables kernel developers to inform KCSAN that a given variable is a shared variable without needing to mark each and every access.

sparc32,parisc,csky: Provide one-byte and two-byte cmpxchg() support
This series provides native one-byte and two-byte cmpxchg() support
for sparc32 and parisc, courtesy of Al Viro. This support is provided
by the same hashed-array-of-locks technique used for the other atomic
operations provided for these two platforms.
This series also provides emulated one-byte cmpxchg() support for csky
using a new cmpxchg_emu_u8() function that uses a four-byte cmpxchg()
to emulate the one-byte variant.
Similar patches for emulation of one-byte cmpxchg() for arc, sh, and
xtensa have not yet received maintainer acks, so they are slated for
the v6.11 merge window.

alpha: cleanups and build fixes
I had investigated dropping support for alpha EV5 and earlier a while
ago after noticing that this is the only supported CPU family
in the kernel without native byte access and that Debian has already
dropped support for this generation last year [1] in order to
improve performance for the newer machines.
This topic came up again when Paul E. McKenney noticed that
parts of the RCU code already rely on byte access and do not
work on alpha EV5 reliably, so we decided on using my series to
avoid the problem entirely.
Al Viro did another series for alpha to address all the known build
issues. I rebased his patches without any further changes and included
it as a baseline for my work here to avoid conflicts and allow
backporting the fixes to stable kernels for the now removed hardware
support as well.

[ I dearly loved alpha back in the days, but the lack of byte and word
operations was a horrible mistake and made everything worse -
including very much the crazy IO contortions that resulted from it.
It certainly wasn't the only mistake in the architecture, but it's the
first-order issue.
So while it's a bit sad to see the support for my first alpha go away,
if you want to run museum hardware, maybe you should use museum
kernels.. - Linus ]

soc: drivers for 6.10
As usual, these are updates for drivers that are specific to certain
SoCs or firmware running on them. Notable updates include
- The new STMicroelectronics STM32 "firewall" bus driver that is
used to provide a barrier between different parts of an SoC
- Lots of updates for the Qualcomm platform drivers, in particular
SCM, which gets a rewrite of its initialization code
- Firmware driver updates for Arm FF-A notification interrupts
and indirect messaging, SCMI firmware support for pin control
and vendor specific interfaces, and TEE firmware interface
changes across multiple TEE drivers
- A larger cleanup of the Mediatek CMDQ driver and some related bits

Merge tag 'soc-drivers-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC driver updates from Arnd Bergmann:
"As usual, these are updates for drivers that are specific to certain
SoCs or firmware running on them.
Notable updates include
- The new STMicroelectronics STM32 "firewall" bus driver that is used
to provide a barrier between different parts of an SoC
- Lots of updates for the Qualcomm platform drivers, in particular
SCM, which gets a rewrite of its initialization code
- Firmware driver updates for Arm FF-A notification interrupts and
indirect messaging, SCMI firmware support for pin control and
vendor specific interfaces, and TEE firmware interface changes
across multiple TEE drivers
- A larger cleanup of the Mediatek CMDQ driver and some related bits
- Kconfig changes for riscv drivers to prepare for adding Kanaan k230
support
- Multiple minor updates for the TI sysc bus driver, memory
controllers, hisilicon hccs and more"

soc: devicetree updates for 6.10, part 1
The updates this time are a bit smaller than most times, mainly because
it is not totally dominated by new Qualcomm hardware support. Instead,
we larger than average updates for Rockchips, NXP, Allwinner and TI.
The only two new SoCs this time are both from NXP and are minor variants
of already supported ones.
The updates for aspeed, amlogic and mediatek came a little late, so
I'm saving those for part 2 in a few days if everything turns out fine.
New machines this time contain:
- two Broadcom SoC based wireless routers from Asus
- Five allwinner based consumer devices for gaming, set-top-box and
eboot reader applications
- Three older phones based on Qualcomm chips, plus the more recent
Sony Xperia 1 V
- 14 industrial and embedded boards based on NXP i.MX6, i.MX8,
layerscape and s32g3 SoCs
- six rockchips boards including another handheld game console
and a few single-board computers
On top of these, we have the usual cleanups for dtc warnings and
updates to add more features to already merged machines.

This enables support of new CMG data formats in userspace without the need for kernel changes - Add a per-channel-path sysfs attribute "speed_bps" that provides the operating speed in bits per second or 0 if the operating speed is not available - The CIO tracepoint subchannel-type field "st" is incorrectly set to the value of subchannel-enabled SCHIB "ena" field. Fix that - Do not forcefully limit vmemmap starting address to MAX_PHYSMEM_BITS - Consider the maximum physical address available to a DCSS segment (512GB) when memory layout is set up - Simplify the virtual memory layout setup by reducing the size of identity mapping vs vmemmap overlap - Swap vmalloc and Lowcore/Real Memory Copy areas in virtual memory. This will allow to place the kernel image next to kernel modules - Move everyting KASLR related from <asm/setup.h> to <asm/page.h> - Put virtual memory layout information into a structure to improve code generation - Currently __kaslr_offset is the kernel offset in both physical and virtual memory spaces. Uncouple these offsets to allow uncoupling of the addresses spaces - Currently the identity mapping base address is implicit and is always set to zero. Make it explicit by putting into __identity_base persistent boot variable and use it in proper context - Introduce .amode31 section start and end macros AMODE31_START and AMODE31_END - Introduce OS_INFO entries that do not reference any data in memory, but rather provide only values - Store virtual memory layout in OS_INFO. It is read out by makedumpfile, crash and other tools - Store virtual memory layout in VMCORE_INFO. It is read out by crash and other tools when /proc/kcore device is used - Create additional PT_LOAD ELF program header that covers kernel image only, so that vmcore tools could locate kernel text and data when virtual and physical memory spaces are uncoupled - Uncouple physical and virtual address spaces - Map kernel at fixed location when KASLR mode is disabled. The location is defined by CONFIG_KERNEL_IMAGE_BASE kernel configuration value. - Rework deployment of kernel image for both compressed and uncompressed variants as defined by CONFIG_KERNEL_UNCOMPRESSED kernel configuration value - Move .vmlinux.relocs section in front of the compressed kernel. The interim section rescue step is avoided as result - Correct modules thunk offset calculation when branch target is more than 2GB away - Kernel modules contain their own set of expoline thunks. Now that the kernel modules area is less than 4GB away from kernel expoline thunks, make modules use kernel expolines. Also make EXPOLINE_EXTERN the default if the compiler supports it - userfaultfd can insert shared zeropages into processes running VMs, but that is not allowed for s390. Fallback to allocating a fresh zeroed anonymous folio and insert that instead - Re-enable shared zeropages for non-PV and non-skeys KVM guests - Rename hex2bitmap() to ap_hex2bitmap() and export it for external use - Add ap_config sysfs attribute to provide the means for setting or displaying adapters, domains and control domains assigned to a vfio-ap mediated device in a single operation - Make vfio_ap_mdev_link_queue() ignore duplicate link requests - Add write support to ap_config sysfs attribute to allow atomic update a vfio-ap mediated device state - Document ap_config sysfs attribute - Function os_info_old_init() is expected to be called only from a regular kdump kernel. Enable it to be called from a stand-alone dump kernel - Address gcc -Warray-bounds warning and fix array size in struct os_info - s390 does not support SMBIOS, so drop unneeded CONFIG_DMI checks - Use unwinder instead of __builtin_return_address() with ftrace to prevent returning of undefined values - Sections .hash and .gnu.hash are only created when CONFIG_PIE_BUILD kernel is enabled. Drop these for the case CONFIG_PIE_BUILD is disabled - Compile kernel with -fPIC and link with -no-pie to allow kpatch feature always succeed and drop the whole CONFIG_PIE_BUILD option-enabled code - Add missing virt_to_phys() converter for VSIE facility and crypto control blocks -----BEGIN PGP SIGNATURE----- iI0EABYIADUWIQQrtrZiYVkVzKQcYivNdxKlNrRb8AUCZjkp5xccYWdvcmRlZXZA bGludXguaWJtLmNvbQAKCRDNdxKlNrRb8D99AQCEby+KHssuZe9m0NvvikWREYBC myqob4EmdU3KdTEbNAEAt2OB7mzSQc90yjawI+Je7vwVyh3uc2Nb4Qg05yO6owI= =eOYN -----END PGP SIGNATURE----- Merge tag 's390-6.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Alexander Gordeev: - Store AP Query Configuration Information in a static buffer - Rework the AP initialization and add missing cleanups to the error path - Swap IRQ and AP bus/device registration to avoid race conditions - Export prot_virt_guest symbol - Introduce AP configuration changes notifier interface to facilitate modularization of the AP bus - Add CONFIG_AP kernel configuration option to allow modularization of the AP bus - Rework CONFIG_ZCRYPT_DEBUG kernel configuration option description and dependency and rename it to CONFIG_AP_DEBUG - Convert sprintf() and snprintf() to sysfs_emit() in CIO code - Adjust indentation of RELOCS command build step - Make crypto performance counters upward compatible - Convert make_page_secure() and gmap_make_secure() to use folio - Rework channel-utilization-block (CUB) handling in preparation of introducing additional CUBs - Use attribute groups to simplify registration, removal and extension of measurement-related channel-path sysfs attributes - Add a per-channel-path binary "ext_measurement" sysfs attribute that provides access to extended channel-path measurement data - Export measurement data for all channel-measurement-groups (CMG), not only for a specific ones.

As reported by Kernel Test Robot and Sean Christopherson, some tests fail since v6.9-rc1 . This is due to the use of vfork() which introduced some side effects. Similarly, while making it more generic, a previous commit made some Landlock file system tests flaky, and subject to the host's file system mount configuration. This fixes all these side effects by replacing vfork() with clone3() and CLONE_VFORK, which is cleaner (no arbitrary shared memory) and makes the Kselftest framework more robust" Link: https://lore.kernel.org/oe-lkp/202403291015.1fcfa957-oliver.sang@intel.com Link: https://lore.kernel.org/r/ZjPelW6-AbtYvslu@google.com Link: https://lore.kernel.org/r/20240511171445.904356-1-mic@digikod.net * tag 'kselftest-fix-vfork-2024-05-12' of git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux: selftests/harness: Handle TEST_F()'s explicit exit codes selftests/harness: Fix vfork() side effects selftests/harness: Share _metadata between forked processes selftests/pidfd: Fix wrong expectation selftests/harness: Constify fixture variants selftests/landlock: Do not allocate memory in fixture data selftests/harness: Fix interleaved scheduling leading to race conditions selftests/harness: Fix fixture teardown selftests/landlock: Fix FS tests when run on a private mount point selftests/pidfd: Fix config for pidfd_setns_test |

selftests/harness: Handle TEST_F()'s explicit exit codes
If TEST_F() explicitly calls exit(code) with code different than 0, then
_metadata->exit_code is set to this code (e.g. KVM_ONE_VCPU_TEST()). We
need to keep in mind that _metadata->exit_code can be KSFT_SKIP while
the process exit code is 0.

selftests/harness: Fix vfork() side effects
Setting the time namespace with CLONE_NEWTIME returns -EUSERS if the
calling thread shares memory with another thread (because of the shared
vDSO), which is the case when it is created with vfork().
Fix pidfd_setns_test by replacing test harness's vfork() call with a
clone3() call with CLONE_VFORK, and an explicit sharing of the
_metadata and self objects.
Replace _metadata->teardown_parent with a new FIXTURE_TEARDOWN_PARENT()
helper that can replace FIXTURE_TEARDOWN(). This is a cleaner approach
and it enables to selectively share the fixture data between the child
process running tests and the parent process running the fixture
teardown. This also avoids updating several tests to not rely on the
self object's copy-on-write property (e.g. storing the returned value of
a fork() call).

selftests/harness: Share _metadata between forked processes
Unconditionally share _metadata between all forked processes, which enables to actually catch errors which were previously ignored. This is required for a following commit replacing vfork() with clone3() and CLONE_VFORK (i.e. not sharing the full memory) . It should also be useful to share _metadata to extend expectations to test process's forks. For instance, this change identified a wrong expectation in pidfd_setns_test. Because this _metadata is used by the new XFAIL_ADD(), use a global pointer initialized in TEST_F(). This is OK because only XFAIL_ADD() use it, and XFAIL_ADD() already depends on TEST_F().

selftests/harness: Fix interleaved scheduling leading to race conditions
Fix a race condition when running several FIXTURE_TEARDOWN() managing
the same resource. This fixes a race condition in the Landlock file
system tests when creating or unmounting the same directory.
Using clone3() with CLONE_VFORK guarantees that the child and grandchild
test processes are sequentially scheduled. This is implemented with a
new clone3_vfork() helper replacing the fork() call.
This avoids triggering this error in __wait_for_test():

According to the test environment, the mount point of the test's working

Pull gpio fixes from Bartosz Golaszewski:
"Some last-minute fixes for this release from the GPIO subsystem.
The first two address a regression in performance reported to me after
the conversion to using SRCU in GPIOLIB that was merged during the
v6.9 merge window. The second patch is not technically a fix but since
after the first one we no longer need to use a per-descriptor SRCU
struct, I think it's worth to simplify the code before it gets
released on Sunday.
The next two commits fix two memory issues: one use-after-free bug and
one instance of possibly leaking kernel stack memory to user-space.
