io_uring/filetable: clamp alloc_hint to the configured alloc range
Explicit fixed file install/remove operations on slots outside the
configured alloc range can corrupt alloc_hint via io_file_bitmap_set()
and io_file_bitmap_clear(), which unconditionally update alloc_hint to
the bit position. This causes subsequent auto-allocations to fall
outside the configured range.
For example, if the alloc range is [10, 20) and a file is removed at
slot 2, alloc_hint gets set to 2. The next auto-alloc then starts
searching from slot 2, potentially returning a slot below the range.
Fix this by clamping alloc_hint to [file_alloc_start, file_alloc_end)
at the top of io_file_bitmap_get() before starting the search.

workqueue: Changes for v6.20
- Rework the rescuer to process work items one-by-one instead of slurping all pending work items in a single pass. As there is only one rescuer per workqueue, a single long-blocking work item could cause high latency for all tasks queued behind it, even after memory pressure is relieved and regular kworkers become available to service them. - Add CONFIG_BOOTPARAM_WQ_STALL_PANIC build-time option and workqueue.panic_on_stall_time parameter for time-based stall panic, giving systems more control over workqueue stall handling. - Replace BUG_ON() with panic() in the stall panic path for clearer intent and more informative output. -----BEGIN PGP SIGNATURE----- iIQEABYKACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCaYov/A4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGWXnAQCfyELl+evz3RdFhyTiVCM1TiOnC1TsBjgkm3SJ orMhwgEAkgg40jino34wgeZRfdIAThxQ1O6bsvTpooWKjlCYcQY= =zZCF -----END PGP SIGNATURE----- Merge tag 'wq-for-6.20' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq Pull workqueue updates from Tejun Heo: - Rework the rescuer to process work items one-by-one instead of slurping all pending work items in a single pass.

sched/mmcid: Don't assume CID is CPU owned on mode switch
Shinichiro reported a KASAN UAF, which is actually an out of bounds access
in the MMCID management code.
CPU0 CPU1
T1 runs in userspace
T0: fork(T4) -> Switch to per CPU CID mode
fixup() set MM_CID_TRANSIT on T1/CPU1
T4 exit()
T3 exit()
T2 exit()
T1 exit() switch to per task mode
---> Out of bounds access.
As T1 has not scheduled after T0 set the TRANSIT bit, it exits with the
TRANSIT bit set. sched_mm_cid_remove_user() clears the TRANSIT bit in
the task and drops the CID, but it does not touch the per CPU storage.
That's functionally correct because a CID is only owned by the CPU when
the ONCPU bit is set, which is mutually exclusive with the TRANSIT flag.
Now sched_mm_cid_exit() assumes that the CID is CPU owned because the
prior mode was per CPU. It invokes mm_drop_cid_on_cpu() which clears the
not set ONCPU bit and then invokes clear_bit() with an insanely large
bit number because TRANSIT is set (bit 29).
Prevent that by actually validating that the CID is CPU owned in
mm_drop_cid_on_cpu().

ACPI: button: Call device_init_wakeup() earlier during probe
Calling device_init_wakeup() after installing a notify handler in which
wakeup events are signaled may cause a wakeup event to be missed if the
device is probed right before a system suspend.
To avoid this, move the device_init_wakeup() call in acpi_button_probe()
before the notify handler installation and add a corresponding cleanup
to the error path.
Also carry out wakeup cleanup for the button in acpi_button_remove()
because after that point the notify handler will not run for it and
wakeup events coming from it will not be signaled.

ACPI: battery: Drop redundant check from acpi_battery_notify()
The battery pointer check against NULL in acpi_battery_notify() is redundant because the value of that pointer is the one passed to acpi_dev_install_notify_handler() in acpi_battery_probe() as the last argument which is not NULL. Drop the redundant check. No intentional functional impact. Closes: https://lore.kernel.org/linux-acpi/aYXvS1h3Bxf_5sCj@stanley.mountain/ Signed-off-by: Rafael J.

powercap: intel_rapl: Expose all package CPUs in PMU cpumask
Currently, the RAPL PMU cpumask only includes one CPU per package (typically the lead_cpu) for both MSR and TPMI interfaces. This forces tools to pin their operations to that specific CPU, even though package-scoped registers are readable from any CPU within the package. Change the cpumask to include all online CPUs in each package. This allows tools like perf and turbostat to read RAPL events from any CPU in the package without requiring special handling to find and use the designated lead_cpu. The change refactors get_pmu_cpu() into set_pmu_cpumask() which populates the cpumask with all CPUs belonging to each RAPL package instead of returning a single CPU. This improves flexibility for userspace tools while maintaining correctness since package-scoped RAPL MSRs are architecturally accessible from any CPU in the package.

powercap: intel_rapl: Remove incorrect CPU check in PMU context
The RAPL MSR read path incorrectly validates CPU context when called
from the PMU subsystem:
if (atomic) {
if (unlikely(smp_processor_id() != cpu))
return -EIO;
rdmsrq(ra->reg.msr, ra->value);
}
This check fails for package-scoped MSRs like RAPL energy counters,
which are readable from any CPU within the package.
The perf tool avoids hitting this check by validating against
/sys/bus/event_source/devices/power/cpumask before opening events.
However, turbostat does not perform this validation and may attempt
reads from non-lead CPUs, causing the check to fail and return zero
power values.
Since package-scoped MSRs are architecturally accessible from any CPU
in the package, remove the CPU matching check.
Also rename 'atomic' to 'pmu_ctx' to clarify this indicates PMU context
where rdmsrq() can be used directly instead of rdmsrl_safe_on_cpu().

firewire updates for v7.0
This update includes the following changes.
- Refactor page allocation dedicated to 1394 OHCI IR/IT/AR DMA contexts
Although 1394 OHCI specification does not impose any restriction on
the memory size dedicated to these DMA contexts, 1394 OHCI PCI driver
allocates pages for convenience when mapping them into either kernel
space or userspace VMA. The driver previously used dma_alloc_pages()
for both page allocation and mapping creation, even though this kernel
API is rarely used. Following discussions questioning the page-oriented
kernel API in the DMA layer, the driver has been refactored to avoid
using this API. In addition, the use of private members in the
allocated pages has been removed following long-standing concern.
- Allocate variable-sized buffer for isochronous context header
1394 OHCI PCI driver previously allocated a single page for isochronous
context header. As a result, the buffer size for the header was fixed
to PAGE_SIZE, which imposed a limitation on IEC 61883-1/6 packet
streaming engine. Consequently, the ALSA PCM devices provided by
drivers for audio and music units in IEEE 1394 bus were constrained in
the maximum size of buffer period (64 ms in most cases). This limitation
is resolved by dynamically allocating the header buffer with an
arbitrary size.

Pull firewire updates from Takashi Sakamoto:
- Refactor page allocation dedicated to 1394 OHCI IR/IT/AR DMA contexts
Although 1394 OHCI specification does not impose any restriction on
the memory size dedicated to these DMA contexts, 1394 OHCI PCI driver
allocates pages for convenience when mapping them into either kernel
space or userspace VMA. The driver previously used dma_alloc_pages()
for both page allocation and mapping creation, even though this
kernel API is rarely used. Following discussions questioning the
page-oriented kernel API in the DMA layer, the driver has been
refactored to avoid using this API. In addition, the use of private
members in the allocated pages has been removed following
long-standing concern.
- Allocate variable-sized buffer for isochronous context header
1394 OHCI PCI driver previously allocated a single page for
isochronous context header. As a result, the buffer size for the
header was fixed to PAGE_SIZE, which imposed a limitation on IEC
61883-1/6 packet streaming engine. Consequently, the ALSA PCM devices
provided by drivers for audio and music units in IEEE 1394 bus were
constrained in the maximum size of buffer period (64 ms in most
cases). This limitation is resolved by dynamically allocating the
header buffer with an arbitrary size.

drm/xe: Make xe_modparam.force_vram_bar_size signed
vram_bar_size is registered as an int module parameter and is documented
to accept negative values to disable BAR resizing.
Store it as an int in xe_modparam as well, so negative values work as
intended and the module_param type matches.

ceph: assert loop invariants in ceph_writepages_start()
If `locked_pages` is zero, the page array must not be allocated: ceph_process_folio_batch() uses `locked_pages` to decide when to allocate `pages`, and redundant allocations trigger ceph_allocate_page_array()'s BUG_ON(), resulting in a worker oops (and writeback stall) or even a kernel panic. Consequently, the main loop in ceph_writepages_start() assumes that the lifetime of `pages` is confined to a single iteration. This expectation is currently not clear enough, as evidenced by the recent patch which fixed an oops caused by `pages` persisting into the next loop iteration: - "ceph: do not propagate page array emplacement errors as batch errors" Use an explicit BUG_ON() at the top of the loop to assert the loop's preexisting expectation that `pages` is cleaned up by the previous iteration. Because this is closely tied to `locked_pages`, also make it the previous iteration's responsibility to guarantee its reset, and verify with a second new BUG_ON() instead of handling (and masking) failures to do so. This patch does not change invariants, behavior, or failure modes. The added BUG_ON() lines catch conditions that would already trigger oops, but do so earlier for easier debugging and programmer clarity.

KVM mediated PMU support for 6.20 Add support for mediated PMUs, where KVM gives the guest full ownership of PMU hardware (contexted switched around the fastpath run loop) and allows direct access to data MSRs and PMCs (restricted by the vPMU model), but intercepts access to control registers, e.g. to enforce event filtering and to prevent the guest from profiling sensitive host state. To keep overall complexity reasonable, mediated PMU usage is all or nothing for a given instance of KVM (controlled via module param). The Mediated PMU is disabled default, partly to maintain backwards compatilibity for existing setup, partly because there are tradeoffs when running with a mediated PMU that may be non-starters for some use cases, e.g. the host loses the ability to profile guests with mediated PMUs, the fastpath run loop is also a blind spot, entry/exit transitions are more expensive, etc. Versus the emulated PMU, where KVM is "just another perf user", the mediated PMU delivers more accurate profiling and monitoring (no risk of contention and thus dropped events), with significantly less overhead (fewer exits and faster emulation/programming of event selectors) E.g. when running Specint-2017 on a single-socket Sapphire Rapids with 56 cores and no-SMT, and using perf from within the guest: Perf command: a. basic-sampling: perf record -F 1000 -e 6-instructions -a --overwrite b. multiplex-sampling: perf record -F 1000 -e 10-instructions -a --overwrite Guest performance overhead: --------------------------------------------------------------------------- | Test case | emulated vPMU | all passthrough | passthrough with | | | | | event filters | --------------------------------------------------------------------------- | basic-sampling | 33.62% | 4.24% | 6.21% | --------------------------------------------------------------------------- | multiplex-sampling | 79.32% | 7.34% | 10.45% | --------------------------------------------------------------------------- |

KVM x86 APIC-ish changes for 6.20 - Fix a benign bug where KVM could use the wrong memslots (ignored SMM) when creating a vCPU-specific mapping of guest memory. - Clean up KVM's handling of marking mapped vCPU pages dirty. - Drop a pile of *ancient* sanity checks hidden behind in KVM's unused ASSERT() macro, most of which could be trivially triggered by the guest and/or user, and all of which were useless. - Fold "struct dest_map" into its sole user, "struct rtc_status", to make it more obvious what the weird parameter is used for, and to allow burying the RTC shenanigans behind CONFIG_KVM_IOAPIC=y. - Bury all of ioapic.h and KVM_IRQCHIP_KERNEL behind CONFIG_KVM_IOAPIC=y. - Add a regression test for recent APICv update fixes. - Rework KVM's handling of VMCS updates while L2 is active to temporarily switch to vmcs01 instead of deferring the update until the next nested VM-Exit. The deferred updates approach directly contributed to several bugs, was proving to be a maintenance burden due to the difficulty in auditing the correctness of deferred updates, and was polluting "struct nested_vmx" with a growing pile of booleans. - Handle "hardware APIC ISR", a.k.a. SVI, updates in kvm_apic_update_apicv() to consolidate the updates, and to co-locate SVI updates with the updates for KVM's own cache of ISR information. - Drop a dead function declaration. |

KVM guest_memfd changes for 6.20 - Remove kvm_gmem_populate()'s preparation tracking and half-baked hugepage handling, and instead rely on SNP (the only user of the tracking) to do its own tracking via the RMP. - Retroactively document and enforce (for SNP) that KVM_SEV_SNP_LAUNCH_UPDATE and KVM_TDX_INIT_MEM_REGION require the source page to be 4KiB aligned, to avoid non-trivial complexity for a non-existent usecase (and because in-place conversion simply can't support unaligned sources). - When populating guest_memfd memory, GUP the source page in common code and pass the refcounted page to the vendor callback, instead of letting vendor code do the heavy lifting. Doing so avoids a looming deadlock bug with in-place due an AB-BA conflict betwee mmap_lock and guest_memfd's filemap invalidate lock. |

spi: Updates for v7.0
The highlight here is that David Lechner has added support for multi-lane
SPI devices. Unlike the existing dual/quad SPI support this is for
devices (typically ADCs/DACs) which support multiple independent data
streams over multiple data lanes, instead of sending one data stream N
times as fast they simultaneously transfer N different data streams.
This is very similar to the case where multiple devices are grouped
together but in this case it's a single device in a way that's visible
to software.
Otherwise there's been quite a bit of work on existing drivers, both
cleanup and feature improvement, and a reasonable collection of new
drivers.
- Support for multi-lane SPI devices.
- Preparatory work for some memory mapped flash improvements that will
happen in the MTD subsystem.
- Several conversions to fwnode APIs.
- A bunch of cleanup and hardening work on the ST drivers.
- Support for DMA mode on Renesas RZV2H and i.MX target mode.
- Support for ATCSPI200, AXIADO AX300, NXP XPI and Renesas RZ/N1.

block: allow IOC_PR_READ_* ioctls with BLK_OPEN_READ
The recently added IOC_PR_READ_* ioctls require the same BLK_OPEN_WRITE permission as the older persistent reservation ioctls. This has the drawback that udev triggers when the file descriptor is closed, resulting in unnecessary activity like scanning partitions even though these read-only ioctls do not modify the device. Change IOC_PR_READ_KEYS and IOC_PR_READ_RESERVATION to require BLK_OPEN_READ. This prevents unnecessary activity every time `blkpr --read-keys` or `blkpr --read-reservation` is invoked by shell scripts, for example. It is safe to reduce the permission requirement from BLK_OPEN_WRITE to BLK_OPEN_READ since these two ioctls do not modify the persistent reservation state. Userspace cannot use the information fetched by these ioctls to make changes to the device unless it later opens the device with BLK_OPEN_WRITE. Fixes: |

drbd: always set BLK_FEAT_STABLE_WRITES
DRBD requires stable pages because it may read the same bio data
multiple times for local disk I/O and network transmission, and in
some cases for calculating checksums.
The BLK_FEAT_STABLE_WRITES flag is set when the device is first
created, but blk_set_stacking_limits() clears it whenever a
backing device is attached. In some cases the flag may be
inherited from the backing device, but we want it to be enabled
at all times.
Unconditionally re-enable BLK_FEAT_STABLE_WRITES in
drbd_reconsider_queue_parameters() after the queue parameter
negotiations.
Also, document why we want this flag enabled in the first place.

ceph: remove error return from ceph_process_folio_batch()
Following an earlier commit, ceph_process_folio_batch() no longer returns errors because the writeback loop cannot handle them. Since this function already indicates failure to lock any pages by leaving `ceph_wbc.locked_pages == 0`, and the writeback loop has no way to handle abandonment of a locked batch, change the return type of ceph_process_folio_batch() to `void` and remove the pathological goto in the writeback loop. The lack of a return code emphasizes that ceph_process_folio_batch() is designed to be abort-free: that is, once it commits a folio for writeback, it will not later abandon it or propagate an error for that folio. Any future changes requiring "abort" logic should follow this invariant by cleaning up its array and resetting ceph_wbc.locked_pages appropriately.

ceph: fix write storm on fscrypted files
CephFS stores file data across multiple RADOS objects. An object is the
atomic unit of storage, so the writeback code must clean only folios
that belong to the same object with each OSD request.
CephFS also supports RAID0-style striping of file contents: if enabled,
each object stores multiple unbroken "stripe units" covering different
portions of the file; if disabled, a "stripe unit" is simply the whole
object. The stripe unit is (usually) reported as the inode's block size.
Though the writeback logic could, in principle, lock all dirty folios
belonging to the same object, its current design is to lock only a
single stripe unit at a time. Ever since this code was first written,
it has determined this size by checking the inode's block size.
However, the relatively-new fscrypt support needed to reduce the block
size for encrypted inodes to the crypto block size (see 'fixes' commit),
which causes an unnecessarily high number of write operations (~1024x as
many, with 4MiB objects) and correspondingly degraded performance.
Fix this (and clarify intent) by using i_layout.stripe_unit directly in
ceph_define_write_size() so that encrypted inodes are written back with
the same number of operations as if they were unencrypted.
This patch depends on the preceding commit ("ceph: do not propagate page
array emplacement errors as batch errors") for correctness. While it
applies cleanly on its own, applying it alone will introduce a
regression. This dependency is only relevant for kernels where

ceph: do not propagate page array emplacement errors as batch errors
When fscrypt is enabled, move_dirty_folio_in_page_array() may fail
because it needs to allocate bounce buffers to store the encrypted
versions of each folio. Each folio beyond the first allocates its bounce
buffer with GFP_NOWAIT. Failures are common (and expected) under this
allocation mode; they should flush (not abort) the batch.
However, ceph_process_folio_batch() uses the same `rc` variable for its
own return code and for capturing the return codes of its routine calls;
failing to reset `rc` back to 0 results in the error being propagated
out to the main writeback loop, which cannot actually tolerate any
errors here: once `ceph_wbc.pages` is allocated, it must be passed to
ceph_submit_write() to be freed. If it survives until the next iteration
(e.g. due to the goto being followed), ceph_allocate_page_array()'s
BUG_ON() will oops the worker.
Note that this failure mode is currently masked due to another bug
(addressed next in this series) that prevents multiple encrypted folios
from being selected for the same write.
For now, just reset `rc` when redirtying the folio to prevent errors in
move_dirty_folio_in_page_array() from propagating. Note that
move_dirty_folio_in_page_array() is careful never to return errors on
the first folio, so there is no need to check for that. After this
change, ceph_process_folio_batch() no longer returns errors; its only
remaining failure indicator is `locked_pages == 0`, which the caller
already handles correctly.

tracing: Fix to set write permission to per-cpu buffer_size_kb
Since the per-cpu buffer_size_kb file is writable for changing
per-cpu ring buffer size, the file should have the write access
permission.

bnge/bng_re: Add a new HSI
The HSI is shared between the firmware and the driver and is automatically generated. Add a new HSI for the BNGE driver. The current HSI refers to BNXT, which will become incompatible with ThorUltra devices as the BNGE driver adds more features. The BNGE driver will not use the HSI located in the bnxt folder. Also, add an HSI for ThorUltra RoCE driver.

Merge branch 'net-dsa-initial-support-for-maxlinear-mxl862xx-switches'
Daniel Golle says: ==================== net: dsa: initial support for MaxLinear MxL862xx switches This series adds very basic DSA support for the MaxLinear MxL86252 (5x 2500Base-T PHYs) and MxL86282 (8x 2500Base-T PHYs) switches. In addition to the 2.5G TP ports both switches also come with two SerDes interfaces which can be used either to connect external PHYs or SFP cages, or as CPU port when using the switch with this DSA driver. MxL862xx integrates a firmware running on an embedded processor (based on Zephyr RTOS). Host interaction uses a simple netlink-like API transported over MDIO/MMD. This series includes only what's needed to pass traffic between user ports and the CPU port: relayed MDIO to internal PHYs, basic port enable/disable, and CPU-port special tagging. The SerDes interface of the CPU port is automatically configured by the switch after reset using a board-specific configuration stored together with the firmware in the flash chip attached to the switch, so no action is needed from the driver to setup the interface mode of the CPU port. Also MAC settings of the PHY ports are automatically configured, which means the driver works fine with phylink_mac_ops being all no-op stubs. Multiple follow up series will bring support for setting up the other SerDes PCS interface (ie. not used for the CPU port), bridge, VLAN, ... offloading, and support for using an 802.1Q-based special tag instead of the proprietary 8-byte tag. ==================== Link: https://patch.msgid.link/cover.1770433307.git.daniel@makrotopia.org Signed-off-by: Paolo Abeni <pabeni@redhat.com> |
