Could you consider these extra patches for 6.11-rc1? Two patches add STATX_DIOALIGN and FS_IOC_GETFSSYSFSPATH support and another one gets rid of the remaining page->index in the codebase according to [1]. I tend to resolve them in this cycle since those improvements are actually straight-forward. The remaining fix addresses a LZ4 decompression race introduced in v6.10 found by regular stress tests. All commits have been in -next except for Chao's new reviewed-bys, so I re-pushed them again. No potential merge conflict is observed. [1] https://lore.kernel.org/r/Zp8fgUSIBGQ1TN0D@casper.infradead.org Thanks, Gao Xiang Changes since last update: - Support STATX_DIOALIGN and FS_IOC_GETFSSYSFSPATH; - Fix a race of LZ4 decompression due to recent refactoring; - Another multi-page folio adaption in erofs_bread().

I know this is running extremely late so I have only included bug fixes
and a few small cleanups.
In particular the cleanup
optimization: try to avoid refing the label in apparmor_file_open
is nice to have for scaling on large systems, as it avoids take a ref count when
it isn't necessary. For the file open test resulting in
kernel test robot noticed a 93.1% improvement of will-it-scale.per_process_ops on:
These patches have all been merge tested against your tree as of
this morning and regression tested against your tree as of yesterday.

***************
This merge request is coming late in the -rc1 cycle on purpose. I
wanted to make sure that the merge issues and other problems were all
resoved due to some core api changes (platform and bus structures)
happening in this tree.
You will have merge conflicts with your tree when you pull from here in
the following two files:
drivers/fsi/fsi-occ.c
drivers/reset/reset-meson-audio-arb.c
the resolution for them should be "obvious", and has been in linux-next
for a while now.
You will also get build errors for the following two platform drivers:
drivers/net/ethernet/renesas/rtsn.c
drivers/gpu/drm/stm/lvds.c
due to these new files coming in during the merge window and them not
being in my branch. They too have fixups that have been in linux-next
for a while.
I have all of the above problems resolved in the following branch:
if you want to compare things, OR you can just pull from that point as
well, I can make a signed tag for you there if that makes it simpler.
Sorry for the conflicts,

Driver core changes for 6.11-rc1
Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases to
get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions. It's not all that useful for a "write a whole driver
in rust" type of thing, but the firmware bindings do help out the
phy rust drivers, and the driver core bindings give a solid base on
which others can start their work. There is still a long way to go
here before we have a multitude of rust drivers being added, but
it's a great first step.
- driver core const api changes. This reached across all bus types,
and there are some fix-ups for some not-common bus types that
linux-next and 0-day testing shook out. This work is being done to
help make the rust bindings more safe, as well as the C code, moving
toward the end-goal of allowing us to put driver structures into
read-only memory. We aren't there yet, but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems.

This is the next round of the Rust support. Later than usual, but all the commits have been in linux-next for about 2 weeks. A trivial conflict with the block pull you already merged expected (resolved in linux -next). In addition, there is a small change to the C side from Arnd that akpm ack'ed. Cheers, Miguel Rust changes for v6.11 The highlight is the establishment of a minimum version for the Rust toolchain, including 'rustc' (and bundled tools) and 'bindgen'. The initial minimum will be the pinned version we currently have, i.e. we are just widening the allowed versions. That covers 3 stable Rust releases: 1.78.0, 1.79.0, 1.80.0 (getting released tomorrow), plus beta, plus nightly. This should already be enough for kernel developers in distributions that provide recent Rust compiler versions routinely, such as Arch Linux, Debian Unstable (outside the freeze period), Fedora Linux, Gentoo Linux (especially the testing channel), Nix (unstable) and openSUSE Slowroll and Tumbleweed. In addition, the kernel is now being built-tested by Rust's pre-merge CI. That is, every change that is attempting to land into the Rust compiler is tested against the kernel, and it is merged only if it passes. Similarly, the bindgen tool has agreed to build the kernel in their CI too. Thus, with the pre-merge CI in place, both projects hope to avoid unintentional changes to Rust that break the kernel. This means that, in general, apart from intentional changes on their side (that we will need to workaround conditionally on our side), the upcoming Rust compiler versions should generally work. In addition, the Rust project has proposed getting the kernel into stable Rust (at least solving the main blockers) as one of its three flagship goals for 2024H2 [1]. I would like to thank Niko, Sid, Emilio et al. for their help promoting the collaboration between Rust and the kernel. [1] https://rust-lang.github.io/rust-project-goals/2024h2/index.html#flagship-goals Toolchain and infrastructure: - Support several Rust toolchain versions. - Support several bindgen versions. - Remove 'cargo' requirement and simplify 'rusttest', thanks to 'alloc' having been dropped last cycle. - Provide proper error reporting for the 'rust-analyzer' target. 'kernel' crate: - Add 'uaccess' module with a safe userspace pointers abstraction. - Add 'page' module with a 'struct page' abstraction. - Support more complex generics in workqueue's 'impl_has_work!' macro. 'macros' crate: - Add 'firmware' field support to the 'module!' macro. - Improve 'module!' macro documentation. Documentation: - Provide instructions on what packages should be installed to build the kernel in some popular Linux distributions. - Introduce the new kernel.org LLVM+Rust toolchains. - Explain '#[no_std]'. And a few other small bits.
Constifying ctl_table structs will prevent the modification of
proc_handler function pointers as they would reside in .rodata. To get
there, the proc_handler arguments must first be const qualified which
requires this (fairly large) treewide PR. Sending it in the tail end of
of the merge window after a suggestion from Kees to avoid unneeded merge
conflicts. It has been rebased on top of 7a3fad30fd8b4b5e370906b3c554f64026f56c2f.
I can send it later if it makes more sense on your side; please tell me
what you prefer.
This PR applies on top of what I see as your latest master, but if you
need to generate it, you can do so by executing two commands:
1. Semantic patch: The coccinelle script is here [1]
`make coccicheck MODE=patch SPFLAGS="--in-place --include-headers --smpl-spacing" COCCI=COCCI_SCRIPT`
2. Sed command: The sed script is here [2]
`sed --in-place -f SED_SCRIPT fs/xfs/xfs_sysctl.c kernel/watchdog.c`
This is my first time sending out a semantic patch, so get back to me if
you have issues or prefer some other way of receiving it.
Testing was done in sysctl-testing (0-day) to avoid generating
unnecessary merge conflicts in linux-next. I do not expect any
error/regression given that all changes contained in this PR are
non-functional.

rpmsg updates for v6.11 This corrects interrupt handling in the stm32 remoteproc driver when being attached to an already running remote processor. It fixes invalid kernel-doc and adds missing MODULE_DESCRIPTION() in the rpmsg char driver.
remoteproc updates for v6.11 The maximum amount of DDR memory used by the Mediatek MT8188/MT8195 SCP is increased, to handle new use cases. Handling of optional L1TCM memory is made actually optional. An optimization is introduced to only clear the unused portion of IPI shared buffers, rather than the entire buffer before writing the message. Detection for IPC-only mode in the TI K3 DSP remoteproc driver is corrected. The loglevel of a debug print in the same is lowered from error. Support for attaching to an running remote processor is added to the Xilinx R5F. An in-kernel implementation of the Qualcomm "protected domain mapper" (aka service registry) service is introduced, to remove the dependency on a userspace implementation to detect when the battery monitor and USB Type-C port manager becomes available. This is then integrated with the Qualcomm remoteproc driver. The Qualcomm PAS remoteproc driver gains support for attempting to bust hwspinlocks held by the remote processor when it crashed/stopped. The TI OMAP remoteproc driver is transitioned to use devres helpers for various forms of allocations. Parsing of memory-regions in the i.MX remoteproc driver is improved to avoid a NULL pointer dereference if the phandle reference is empty. of_node reference counting is corrected in the same.
hwspinlock updates for v6.11 This introduces a mechanism in the hardware spinlock framework, and the Qualcomm TCSR mutex driver, for allowing clients to bust locks held by a remote processor in the event that this enters a faulty state while holding the shared lock.
Modules changes for v6.11-rc1 This is a super boring development cycle this time around for modules, there is only one patch in this pull request. The patch deals with a corner case set of dependencies which is not resolved today to ensure users get the modules they need on initramfs. Currently only one modules is known to exist which needs this, however this can grow to capture other corner cases likely escaped and not reported before. The kernel change is just a section update, the real work is done and merged already on upstream kmod. This has been on linux-next for 3 weeks now.
please pull the latest changes for the kernel livepatching from - Show also patch->replace flag in sysfs. - Add or improve few selftests.
please pull the latest printk changes from
Next preparation step for introducing printk kthreads. This part
wires up flushing consoles via con->write_atomic() callback.
The write_atomic() callback can be used for flushing nbcon consoles
in any context. It is needed when the console could not be reliably
flushed using the printk kthread. Namely, it is used:
- During the early boot, from the legacy loop in console_unlock().
It allows to see the messages before processes (kthreads) could
get started.
Note that it must be used as long as there is a boot console
registered. The console_lock() serializes accesses to the same
HW port between the early and normal console driver.
- In an emergency section, directly from nbcon_cpu_emergency_exit()
or nbcon_cpu_emergency_flush(). It allows to see the messages
when the system is in an unexpected state and might not be
able to continue properly.
The messages are flushed at the end of the emergency section
to allow storing the full log (backtrace) first. It helps to
see it even when other CPUs add messages in parallel. The flush()
API is used to explicitly flush parts of longer logs which might
not fit into the buffer or might cause a softlockup.
The emergency section is used for WARN(), Oops, RCU stall,
and lockdep reports.
- In panic(), directly from printk() on the panic-CPU. Note that
other CPUs are not allowed to add new messages at this point.
There is also a new uart_port_lock() API in serial_core.h. It allows to
take port->lock and also acquire the nbcon console context when
the particular port gets registered as a console.
The port->lock serializes code for non-printing activities, for example,
for writing or setting the port speed. The nbcon context allows to
serialize the access in emergency or panic situations where the classic
spin lock (port->lock) could cause a deadlock. Note that the nbcon
context allows a safe takeover in the middle of a printed message.
IMPORTANT: The changes do not affect the behavior of legacy consoles,
except for two situations:
- Legacy consoles are not longer flushed directly from printk()
in emergency sections. The flush is done on exit from
the emergency section or by nbcon_cpu_emergency_flush().
The motivation is the same as for nbcon consoles.
- Legacy consoles are not longer flushed directly from printk()
in panic() when crash dump is created and a nbcon console
is registered. They could create a deadlock in compare with
nbcon consoles.

ation
[ Same as V1 minus the MSI conversion ]
Updates for the interrupt subsystem:
- Core:
- Provide a new mechanism to create interrupt domains. The existing
interfaces have already too many parameters and it's a pain to expand
any of this for new required functionality.
The new function takes a pointer to a data structure as argument. The
data structure combines all existing parameters and allows for easy
extension.
The first extension for this is to handle the instantiation of
generic interrupt chips at the core level and to allow drivers to
provide extra init/exit callbacks.
This is necessary to do the full interrupt chip initialization before
the new domain is published, so that concurrent usage sites won't see
a half initialized interrupt domain. Similar problems exist on
teardown.
This has turned out to be a real problem due to the deferred and
parallel probing which was added in recent years.
Handling this at the core level allows to remove quite some accrued
boilerplate code in existing drivers and avoids horrible workarounds
at the driver level.
- The usual small improvements all over the place
- Drivers
- Add support for LAN966x OIC and RZ/Five SoC
- Split the STM ExtI driver into a microcontroller and a SMP version to
allow building the latter as a module for multi-platform kernels.
- Enable MSI support for Armada 370XP on platforms which do not support
IPIs.
- The usual small fixes and enhancements all over the place.
Thanks,

- 875fa64577da ("mm/hugetlb_vmemmap: fix race with speculative PFN
walkers") is known to cause a performance regression
(https://lore.kernel.org/all/3acefad9-96e5-4681-8014-827d6be71c7a@linux.i=
bm.com/T/#mfa809800a7862fb5bdf834c6f71a3a5113eb83ff).
Yu has a fix which I'll send along later via the hotfixes branch.
- In the series "mm: Avoid possible overflows in dirty throttling" Jan
Kara addresses a couple of issues in the writeback throttling code.
These fixes are also targetted at -stable kernels.
- Ryusuke Konishi's series "nilfs2: fix potential issues related to
reserved inodes" does that. This should actually be in the
mm-nonmm-stable tree, along with the many other nilfs2 patches. My bad.
- More folio conversions from Kefeng Wang in the series "mm: convert to
folio_alloc_mpol()"
- Kemeng Shi has sent some cleanups to the writeback code in the series
"Add helper functions to remove repeated code and improve readability of
cgroup writeback"
- Kairui Song has made the swap code a little smaller and a little
faster in the series "mm/swap: clean up and optimize swap cache index".
- In the series "mm/memory: cleanly support zeropage in
vm_insert_page*(), vm_map_pages*() and vmf_insert_mixed()" David
Hildenbrand has reworked the rather sketchy handling of the use of the
zeropage in MAP_SHARED mappings. I don't see any runtime effects here -
more a cleanup/understandability/maintainablity thing.
- Dev Jain has improved selftests/mm/va_high_addr_switch.c's handling of
higher addresses, for aarch64. The (poorly named) series is
"Restructure va_high_addr_switch".
- The core TLB handling code gets some cleanups and possible slight
optimizations in Bang Li's series "Add update_mmu_tlb_range() to
simplify code".
- Jane Chu has improved the handling of our
fake-an-unrecoverable-memory-error testing feature MADV_HWPOISON in the
series "Enhance soft hwpoison handling and injection".
- Jeff Johnson has sent a billion patches everywhere to add
MODULE_DESCRIPTION() to everything. Some landed in this pull.
- In the series "mm: cleanup MIGRATE_SYNC_NO_COPY mode", Kefeng Wang has
simplified migration's use of hardware-offload memory copying.
- Yosry Ahmed performs more folio API conversions in his series "mm:
zswap: trivial folio conversions".
- In the series "large folios swap-in: handle refault cases first",
Chuanhua Han inches us forward in the handling of large pages in the
swap code. This is a cleanup and optimization, working toward the end
objective of full support of large folio swapin/out.
- In the series "mm,swap: cleanup VMA based swap readahead window
calculation", Huang Ying has contributed some cleanups and a possible
fixlet to his VMA based swap readahead code.
- In the series "add mTHP support for anonymous shmem" Baolin Wang has
taught anonymous shmem mappings to use multisize THP. By default this
is a no-op - users must opt in vis sysfs controls. Dramatic
improvements in pagefault latency are realized.
- David Hildenbrand has some cleanups to our remaining use of
page_mapcount() in the series "fs/proc: move page_mapcount() to
fs/proc/internal.h".
- David also has some highmem accounting cleanups in the series
"mm/highmem: don't track highmem pages manually".
- Build-time fixes and cleanups from John Hubbard in the series
"cleanups, fixes, and progress towards avoiding "make headers"".
- Cleanups and consolidation of the core pagemap handling from Barry
Song in the series "mm: introduce pmd|pte_needs_soft_dirty_wp helpers
and utilize them".
- Lance Yang's series "Reclaim lazyfree THP without splitting" has
reduced the latency of the reclaim of pmd-mapped THPs under fairly
common circumstances. A 10x speedup is seen in a microbenchmark.
It does this by punting to aother CPU but I guess that's a win unless
all CPUs are pegged.
- hugetlb_cgroup cleanups from Xiu Jianfeng in the series
"mm/hugetlb_cgroup: rework on cftypes".
- Miaohe Lin's series "Some cleanups for memory-failure" does just that
thing.
- Is anyone reading this stuff? If so, email me!
- Someone other than SeongJae has developed a DAMON feature in Honggyu
Kim's series "DAMON based tiered memory management for CXL memory".
This adds DAMON features which may be used to help determine the
efficiency of our placement of CXL/PCIe attached DRAM.
- DAMON user API centralization and simplificatio work in SeongJae
Park's series "mm/damon: introduce DAMON parameters online commit
function".
- In the series "mm: page_type, zsmalloc and page_mapcount_reset()"
David Hildenbrand does some maintenance work on zsmalloc - partially
modernizing its use of pageframe fields.
- Kefeng Wang provides more folio conversions in the series "mm: remove
page_maybe_dma_pinned() and page_mkclean()".
- More cleanup from David Hildenbrand, this time in the series
"mm/memory_hotplug: use PageOffline() instead of PageReserved() for
!ZONE_DEVICE". It "enlightens memory hotplug more about PageOffline()
pages" and permits the removal of some virtio-mem hacks.
- Barry Song's series "mm: clarify folio_add_new_anon_rmap() and
__folio_add_anon_rmap()" is a cleanup to the anon folio handling in
preparation for mTHP (multisize THP) swapin.
- Kefeng Wang's series "mm: improve clear and copy user folio"
implements more folio conversions, this time in the area of large folio
userspace copying.
- The series "Docs/mm/damon/maintaier-profile: document a mailing tool
and community meetup series" tells people how to get better involved
with other DAMON developers. From SeongJae Park.
- A large series ("kmsan: Enable on s390") from Ilya Leoshkevich does
that.
- David Hildenbrand sends along more cleanups, this time against the
migration code. The series is "mm/migrate: move NUMA hinting fault
folio isolation + checks under PTL".
- Jan Kara has found quite a lot of strangenesses and minor errors in
the readahead code. He addresses this in the series "mm: Fix various
readahead quirks".
- SeongJae Park's series "selftests/damon: test DAMOS tried regions and
{min,max}_nr_regions" adds features and addresses errors in DAMON's self
testing code.
- Gavin Shan has found a userspace-triggerable WARN in the pagecache
code. The series "mm/filemap: Limit page cache size to that supported
by xarray" addresses this. The series is marked cc:stable.
- Chengming Zhou's series "mm/ksm: cmp_and_merge_page() optimizations
and cleanup" cleans up and slightly optimizes KSM.
- Roman Gushchin has separated the memcg-v1 and memcg-v2 code - lots of
code motion. The series (which also makes the memcg-v1 code
Kconfigurable) are
"mm: memcg: separate legacy cgroup v1 code and put under config
option" and
"mm: memcg: put cgroup v1-specific memcg data under CONFIG_MEMCG_V1"
- Dan Schatzberg's series "Add swappiness argument to memory.reclaim"
adds an additional feature to this cgroup-v2 control file.
- The series "Userspace controls soft-offline pages" from Jiaqi Yan
permits userspace to stop the kernel's automatic treatment of excessive
correctable memory errors. In order to permit userspace to monitor and
handle this situation.
- Kefeng Wang's series "mm: migrate: support poison recover from migrate
folio" teaches the kernel to appropriately handle migration from
poisoned source folios rather than simply panicing.
- SeongJae Park's series "Docs/damon: minor fixups and improvements"
does those things.
- In the series "mm/zsmalloc: change back to per-size_class lock"
Chengming Zhou improves zsmalloc's scalability and memory utilization.
- Vivek Kasireddy's series "mm/gup: Introduce memfd_pin_folios() for
pinning memfd folios" makes the GUP code use FOLL_PIN rather than bare
refcount increments. So these paes can first be moved aside if they
reside in the movable zone or a CMA block.
- Andrii Nakryiko has added a binary ioctl()-based API to /proc/pid/maps
for much faster reading of vma information. The series is "query VMAs
from /proc/<pid>/maps".
- In the series "mm: introduce per-order mTHP split counters" Lance Yang
improves the kernel's presentation of developer information related to
multisize THP splitting.
- Michael Ellerman has developed the series "Reimplement huge pages
without hugepd on powerpc (8xx, e500, book3s/64)". This permits
userspace to use all available huge page sizes.
- In the series "revert unconditional slab and page allocator fault
injection calls" Vlastimil Babka removes a performance-affecting and not
very useful feature from slab fault injection.
this is the bulk of pin control changes for the v6.11 kernel cycle. Some new drivers is the main part, the rest is cleanups and nonurgent fixes. New drivers listed in the signed tag. Nothing much special about this, no core changes this time. Yours, Linus Walleij Pin control bulk changes for the v6.11 kernel series: Core changes: None. New drivers: - Renesas RZ/V2H(P) SoC - NXP Freescale i.MX91 SoC - Nuvoton MA35D1 SoC - Qualcomm PMC8380, SM4250, SM4250 LPI Enhancements: - A slew of scoped-based simplifications of of_node_put().
RISC-V Patches for the 6.11 Merge Window, Part 1
* Support for various new ISA extensions:
* The Zve32[xf] and Zve64[xfd] sub-extensios of the vector
extension.
* Zimop and Zcmop for may-be-operations.
* The Zca, Zcf, Zcd and Zcb sub-extensions of the C extension.
* Zawrs,
* riscv,cpu-intc is now dtschema.
* A handful of performance improvements and cleanups to text patching.

* The highest user-allocatable virtual address is now visible in
hwprobe.
This is the MTD PR for 6.11.
Thanks,
Miqu=C3=A8l
MTD changes:
- Nothing stands out for this merge window, mostly minor fixes, such as
module descriptions, the use of debug macros and Makefile improvements.
Raw NAND changes;
- The Freescale MXC driver has been converted to the newer ->exec_op()
interface. The meson driver now supports handling the boot ROM area
with very specific ECC needs. Support for the iMX8QXP has been added
to the GPMI driver. The lpx32xx driver now can get the DMA channels
using DT entries. The Qcom binding has been improved to be more future
proof by Rob. And then there is the usual load of misc and minor
changes.
SPI-NAND changes:
- The Macronix vendor driver has been improved to support an extended ID
to avoid conflicting with older devices after an ID reuse issue.
SPI NOR changes:
- Drop support for Xilinx S3AN flashes. These flashes are for the very
old Xilinx Spartan 3 FPGAs and they need some awkward code in the core
to support. Drop support for these flashes, along with the special
handling we needed for them in the core like non-power-of-2 page size
handling and the .setup() callback.
- Fix regression for old w25q128 flashes without SFDP tables. Commit
83e824a4a595 ("mtd: spi-nor: Correct flags for Winbond w25q128")
dropped support for such devices under the assumption that they aren't
being used anymore. Users have now surfaced [0] so fix the regression
by supporting both kind of devices.
- Core cleanups including removal of SPI_NOR_NO_FR flag and
simplification of spi_nor_get_flash_info().

oT2=3Du4d4aA@mail.gmail.com/
- added support for Realtek RTL9302C - added support for Mobileye EyeQ6H - added support for Mobileye EyeQ OLB system controller - improved r4k clocksource - added mode for emulating ieee754 NAN2008 - rework for BMIPS CBR address handling - fixes for Loongson 2K1000 - defconfig updates - cleanups and fixes
firewire updates for v6.11 There are many line changes for FireWire subsystem, while there is no functional change for practical use. The most of changes are for code refactoring, some KUnit tests to added helper functions, and new tracepoints events for both the core functions and 1394 OHCI driver. The tracepoints events now cover the verbose logging enabled by debug parameter of firewire-ohci kernel module. The parameter would be removed in any future timing, thus it is now deprecated.
Hi Wolfram, here comes the second part of the merge window pull request. I pull request on top of the mainline. Until now I was on top of your i2c/for-mergewindow branch. Thanks and have a great weekend, Andi Added descriptions in the DTS for the Qualcomm SM8650 and SM8550 Camera Control Interface (CCI). Added support for the "settle-time-us" property, which allows the gpio-mux device to switch from one bus to another with a configurable delay. The time can be set in the DTS. The latest change also includes file sorting. Fixed slot numbering in the SMBus framework to prevent failures when more than 8 slots are occupied. It now enforces a a maximum of 8 slots to be used. This ensures that the Intel PIIX4 device can register the SPDs correctly without failure, even if other slots are populated but not used.

transactions between functions even though it doesn't advertise ACS, so
the functions can be attached individually via VFIO (Ajit Khaparde)
Peer-to-peer DMA:
- Add a "pci=config_acs=" kernel command-line parameter to relax default

Small PR, mainly to unbreak the s390 build. We delayed it a little bit to try to catch a last-minute fix, but it will have to wait a bit more. Notably this includes fixes for a s390 build breakage. Including fixes from netfilter. Current release - new code bugs: - eth: fbnic: fix s390 build. - eth: airoha: fix NULL pointer dereference in airoha_qdma_cleanup_rx_queue() Previous releases - regressions: - flow_dissector: use DEBUG_NET_WARN_ON_ONCE - ipv4: fix incorrect TOS in route get reply - dsa: fix chip-wide frame size config in some drivers Previous releases - always broken: - netfilter: nf_set_pipapo: fix initial map fill - eth: gve: fix XDP TX completion handling when counters overflow Signed-off-by: Paolo Abeni <pabeni@redhat.com>
ARM:
* Initial infrastructure for shadow stage-2 MMUs, as part of nested
virtualization enablement
* Support for userspace changes to the guest CTR_EL0 value, enabling
(in part) migration of VMs between heterogenous hardware
* Fixes + improvements to pKVM's FF-A proxy, adding support for v1.1 of
the protocol
* FPSIMD/SVE support for nested, including merged trap configuration
and exception routing
* New command-line parameter to control the WFx trap behavior under KVM
* Introduce kCFI hardening in the EL2 hypervisor
* Fixes + cleanups for handling presence/absence of FEAT_TCRX
* Miscellaneous fixes + documentation updates
LoongArch:
* Add paravirt steal time support.
* Add support for KVM_DIRTY_LOG_INITIALLY_SET.
* Add perf kvm-stat support for loongarch.
RISC-V:
* Redirect AMO load/store access fault traps to guest
* perf kvm stat support
* Use guest files for IMSIC virtualization, when available
ONE_REG support for the Zimop, Zcmop, Zca, Zcf, Zcd, Zcb and Zawrs ISA
extensions is coming through the RISC-V tree.
s390:
* Assortment of tiny fixes which are not time critical
x86:
* Fixes for Xen emulation.
* Add a global struct to consolidate tracking of host values, e.g. EFER
* Add KVM_CAP_X86_APIC_BUS_CYCLES_NS to allow configuring the effective APIC
bus frequency, because TDX.
* Print the name of the APICv/AVIC inhibits in the relevant tracepoint.
* Clean up KVM's handling of vendor specific emulation to consistently act on
"compatible with Intel/AMD", versus checking for a specific vendor.
* Drop MTRR virtualization, and instead always honor guest PAT on CPUs
that support self-snoop.
* Update to the newfangled Intel CPU FMS infrastructure.
* Don't advertise IA32_PERF_GLOBAL_OVF_CTRL as an MSR-to-be-saved, as it reads
'0' and writes from userspace are ignored.
* Misc cleanups
x86 - MMU:
* Small cleanups, renames and refactoring extracted from the upcoming
Intel TDX support.
* Don't allocate kvm_mmu_page.shadowed_translation for shadow pages that can't
hold leafs SPTEs.
* Unconditionally drop mmu_lock when allocating TDP MMU page tables for eager
page splitting, to avoid stalling vCPUs when splitting huge pages.
* Bug the VM instead of simply warning if KVM tries to split a SPTE that is
non-present or not-huge. KVM is guaranteed to end up in a broken state
because the callers fully expect a valid SPTE, it's all but dangerous
to let more MMU changes happen afterwards.
x86 - AMD:
* Make per-CPU save_area allocations NUMA-aware.
* Force sev_es_host_save_area() to be inlined to avoid calling into an
instrumentable function from noinstr code.
* Base support for running SEV-SNP guests. API-wise, this includes
a new KVM_X86_SNP_VM type, encrypting/measure the initial image into
guest memory, and finalizing it before launching it. Internally,
there are some gmem/mmu hooks needed to prepare gmem-allocated pages
before mapping them into guest private memory ranges.
This includes basic support for attestation guest requests, enough to
say that KVM supports the GHCB 2.0 specification.
There is no support yet for loading into the firmware those signing
keys to be used for attestation requests, and therefore no need yet
for the host to provide certificate data for those keys. To support
fetching certificate data from userspace, a new KVM exit type will be
needed to handle fetching the certificate from userspace. An attempt to
define a new KVM_EXIT_COCO/KVM_EXIT_COCO_REQ_CERTS exit type to handle
this was introduced in v1 of this patchset, but is still being discussed
by community, so for now this patchset only implements a stub version
of SNP Extended Guest Requests that does not provide certificate data.
x86 - Intel:
* Remove an unnecessary EPT TLB flush when enabling hardware.
* Fix a series of bugs that cause KVM to fail to detect nested pending posted
interrupts as valid wake eents for a vCPU executing HLT in L2 (with
HLT-exiting disable by L1).
* KVM: x86: Suppress MMIO that is triggered during task switch emulation
Explicitly suppress userspace emulated MMIO exits that are triggered when
emulating a task switch as KVM doesn't support userspace MMIO during
complex (multi-step) emulation. Silently ignoring the exit request can
result in the WARN_ON_ONCE(vcpu->mmio_needed) firing if KVM exits to
userspace for some other reason prior to purging mmio_needed.
See commit 0dc902267cb3 ("KVM: x86: Suppress pending MMIO write exits if
emulator detects exception") for more details on KVM's limitations with
respect to emulated MMIO during complex emulator flows.
Generic:
* Rename the AS_UNMOVABLE flag that was introduced for KVM to AS_INACCESSIBLE,
because the special casing needed by these pages is not due to just
unmovability (and in fact they are only unmovable because the CPU cannot
access them).
* New ioctl to populate the KVM page tables in advance, which is useful to
mitigate KVM page faults during guest boot or after live migration.
The code will also be used by TDX, but (probably) not through the ioctl.
* Enable halt poll shrinking by default, as Intel found it to be a clear win.
* Setup empty IRQ routing when creating a VM to avoid having to synchronize
SRCU when creating a split IRQCHIP on x86.
* Rework the sched_in/out() paths to replace kvm_arch_sched_in() with a flag
that arch code can use for hooking both sched_in() and sched_out().
* Take the vCPU @id as an "unsigned long" instead of "u32" to avoid
truncating a bogus value from userspace, e.g. to help userspace detect bugs.
* Mark a vCPU as preempted if and only if it's scheduled out while in the
KVM_RUN loop, e.g. to avoid marking it preempted and thus writing guest
memory when retrieving guest state during live migration blackout.
Selftests:
* Remove dead code in the memslot modification stress test.
* Treat "branch instructions retired" as supported on all AMD Family 17h+ CPUs.
* Print the guest pseudo-RNG seed only when it changes, to avoid spamming the
log for tests that create lots of VMs.
* Make the PMU counters test less flaky when counting LLC cache misses by
doing CLFLUSH{OPT} in every loop iteration.
Staging driver updates for 6.11-rc1
This is the "big" staging driver update for 6.11-rc1. Not really all
that much happened this release cycle, just lots of tiny cleanups,
overall about 3000 lines removed, so the cleanups were worth it.
Included in here are:
- loads of rtl8723bs driver cleanups
- lots of rtl8192e driver cleanups
- vc04_services reworks and cleanups as that codebase gets slowly
evolved into something that will make it into the "real" part of the
kernel hopefully soon.
- other tiny staging driver cleanups
All of these have been in linux-next for a while with no reported
issues.

Char/Misc and other driver changes for 6.11-rc1 Here is the "big" set of char/misc and other driver subsystem changes for 6.11-rc1. Nothing major in here, just loads of new drivers and updates. Included in here are: - IIO api updates and new drivers added - wait_interruptable_timeout() api cleanups for some drivers - MODULE_DESCRIPTION() additions for loads of drivers - parport out-of-bounds fix - interconnect driver updates and additions - mhi driver updates and additions - w1 driver fixes - binder speedups and fixes - eeprom driver updates - coresight driver updates - counter driver update - new misc driver additions - other minor api updates All of these, EXCEPT for the final Kconfig build fix for 32bit systems, have been in linux-next for a while with no reported issues. The Kconfig fixup went in 29 hours ago, so might have missed the latest linux-next, but was acked by everyone involved. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
USB/Thunderbolt updates for 6.11-rc1
Here is the big set of USB and Thunderbolt changes for 6.11-rc1.
Nothing earth-shattering in here, just constant forward progress in
adding support for new hardware and better debugging functionalities for
thunderbolt devices and the subsystem. Included in here are:
- thunderbolt debugging update and driver additions
- xhci driver updates
- typec driver updates
- kselftest device driver changes (acked by the relevant maintainers,
depended on other changes in this tree.)
- cdns3 driver updates
- gadget driver updates
- MODULE_DESCRIPTION() additions
- dwc3 driver updates and fixes
All of these have been in linux-next for a while with no reported
issues.

TTY/Serial updates for 6.11-rc1
Here is a small set of tty and serial driver updates for 6.11-rc1. Not
much happened this cycle, unlike the previous kernel release which had
lots of "excitement" in this part of the kernel. Included in here are
the following changes:
- dt binding updates for new platforms
- 8250 driver updates
- various small serial driver fixes and updates
- printk/console naming and matching attempt #2 (was reverted for
6.10-final, should be good to go this time around, acked by the
relevant maintainers).
All of these have been in linux-next for a while with no reported
issues.

I've been looking after the IOMMU tree in Joerg's absence [1] for the
past few weeks and I was expecting him back at the start of this week to
send the pull. However, I've not heard from him at all and figured that
I may as well send this now rather than wait until the second week of
the merge window.
A few minor fixes have started showing up too, so I may end up sending
you a follow-up next week anyway.
A summary of all the changes is included in the tag.
Cheers,
Will

please pull sound updates for v6.11-rc1 from: The topmost commit is 4594d26fca91fab0e1621d2ab196f3f9bab96bc8 sound updates for 6.11-rc1 Lots of changes in this cycle, but mostly for cleanups and refactoring. Significant amount of changes are about DT schema conversions for ASoC at this time while we see other usual suspects, too. Some highlights below: Core: - Re-introduction of PCM sync ID support API - MIDI2 time-base extension in ALSA sequencer API ASoC: - Syncing of features between simple-audio-card and the two audio-graph cards - Support for specifying the order of operations for components within cards to allow quirking for unusual systems - Lots of DT schema conversions - Continued SOF/Intel updates for topology, SoundWire, IPC3/4 - New support for Asahi Kasei AK4619, Cirrus Logic CS530x, Everest Semiconductors ES8311, NXP i.MX95 and LPC32xx, Qualcomm LPASS v2.5 and WCD937x, Realtek RT1318 and RT1320 and Texas Instruments PCM5242 HD-audio: - More quirks, Intel PantherLake support, senarytech codec support - Refactoring of Cirrus codec component-binding Others: - ALSA control kselftest improvements, and fixes for input value checks in various drivers
dma-mapping updates for Linux 6.11 - reduce duplicate swiotlb pool lookups (Michael Kelley) - minor small fixes (Yicong Yang, Yang Li)
Ok, version 2: bcachefs changes for 6.11-rc1 (version 2) Additional fixes on top of the original 6.11 pull request: - undefined behaviour fixes, originally noted as breaking userspace LTO builds - fix a spurious warning in fsck_err, reported by Marcin - fix an integer overflow on trans->nr_updates, also reported by Marcin; this broke during deletion of highly fragmented indirect extents - Add comments for lockdep functions ====== - Metadata version 1.8: Stripe sectors accounting, BCH_DATA_unstriped This splits out the accounting of dirty sectors and stripe sectors in alloc keys; this lets us see stripe buckets that still have unstriped data in them. This is needed for ensuring that erasure coding is working correctly, as well as completing stripe creation after a crash. - Metadata version 1.9: Disk accounting rewrite The previous disk accounting scheme relied heavily on percpu counters that were also sharded by outstanding journal buffer; it was fast but not extensible or scalable, and meant that all accounting counters were recorded in every journal entry. The new disk accounting scheme stores accounting as normal btree keys; updates are deltas until they are flushed by the btree write buffer. This means we have no practical limit on the number of counters, and a new tagged union format that's easy to extend. We now have counters for compression type/ratio, per-snapshot-id usage, per-btree-id usage, and pending rebalance work. - Self healing on read IO/checksum error data is now automatically rewritten if we get a read error and then a successful retry - Mount API conversion (thanks to Thomas Bertschinger) - Better lockdep coverage Previously, btree node locks were tracked individually by lockdep, like any other lock. But we may take _many_ btree node locks simultaneously, we easily blow through the limit of 48 locks that lockdep can track, leading to lockdep turning itself off. Tracking each btree node lock individually isn't really necessary since we have our own cycle detector for deadlock avoidance and centralized tracking of btree node locks, so we now have a single lockdep_map in btree_trans for "any btree nodes are locked". - some more small incremental work towards online check_allocations - lots more debugging improvements, fixes
Nothing hugely exciting happening in the documentation tree this time around, mostly more of the usual: - More Spanish, Italian, and Chinese translations - A new script, scripts/checktransupdate.py, can be used to see which commits have touched an (English) document since a given translation was last updated. - A couple of "best practices" suggestions (on Link: tags and off-list discussions) that were not entirely at consensus level, but I concluded they were close enough to accept. - Some nice cleanups removing documentation for kernel parameters that have not been recognized for ... a long time. ...along with the usual updates, typo fixes, and such.
Just a few commits this cycle. Thanks VFIO updates for v6.11 - Add support for 8-byte accesses when using read/write through the device regions. This fills a gap for userspace drivers that might not be able to use access through mmap to perform native register width accesses. (Gerd Bayer) - Add missing MODULE_DESCRIPTION to vfio-mdev sample drivers and replace a non-standard MODULE_INFO usage. (Jeff Johnson)
This includes the following changes related to sparc for v6.11: - Add MODULE_DESCRIPTION for a number of sbus drivers - Fix linking error for large sparc32 kernels - Fix incorrect functions signature and prototype warnings for sparc64
This is the main drm next pull for 6.11. It has one minor conflict
when I test merged it with your tree.
The gitlab fdo git server seems to be running a bit slow, I think
pulls should be fine, but let me know if you have any issues.
There's a lot of stuff in here, amd, i915 and xe have new platform
work, lots of core rework around EDID handling, some new COMPILE_TEST
options, maintainer changes and a lots of other stuff, summary below.

Dave.

s390 updates for 6.11 merge window
- Remove restrictions on PAI NNPA and crypto counters, enabling
concurrent per-task and system-wide sampling and counting events
- Switch to GENERIC_CPU_DEVICES by setting up the CPU present mask in
the architecture code and letting the generic code handle CPU bring-up
- Add support for the diag204 busy indication facility to prevent
undesirable blocking during hypervisor logical CPU utilization
queries. Implement results caching
- Improve the handling of Store Data SCLP events by suppressing
unnecessary warning, preventing buffer release in I/O during failures,
and adding timeout handling for Store Data requests to address potential
firmware issues
- Provide optimized __arch_hweight*() implementations
- Remove the unnecessary CPU KOBJ_CHANGE uevents generated during topology
updates, as they are unused and also not present on other architectures
- Cleanup atomic_ops, optimize __atomic_set() for small values and
__atomic_cmpxchg_bool() for compilers supporting flag output constraint
- Couple of cleanups for KVM:
- Move and improve KVM struct definitions for DAT tables from gaccess.c
to a new header
- Pass the asce as parameter to sie64a()
- Make the crdte() and cspg() page table handling wrappers return a
boolean to indicate success, like the other existing "compare and swap"
wrappers
- Add documentation for HWCAP flags
- Switch to obtaining total RAM pages from memblock instead of
totalram_pages() during mm init, to ensure correct calculation of zero
page size, when defer_init is enabled
- Refactor lowcore access and switch to using the get_lowcore() function
instead of the S390_lowcore macro
- Cleanups for PG_arch_1 and folio handling in UV and hugetlb code
- Add missing MODULE_DESCRIPTION() macros
- Fix VM_FAULT_HWPOISON handling in do_exception()
x86/percpu changes for v6.11: - Enable the named address spaces based percpu accessors optimization on all GCC versions that contain this feature, detected through a build-time testcase. This effectively enables the feature on GCC 6, GCC 7 and GCC 8 versions. - Fix operand constraint modifier in __raw_cpu_write() - Reorganize the per-CPU headers for better readability - Misc cleanups and fixes Thanks, Ingo
please pull the latest slab updates from: no merge conflicts with other trees expected. Thanks, Vlastimil The most prominent change this time is the kmem_buckets based hardening of kmalloc() allocations from Kees Cook. We have also extended the kmalloc() alignment guarantees for non-power-of-two sizes in a way that benefits rust. The rest are various cleanups and non-critical fixups. - Dedicated bucket allocator (Kees Cook) This series [1] enhances the probabilistic defense against heap spraying/grooming of CONFIG_RANDOM_KMALLOC_CACHES from last year. kmalloc() users that are known to be useful for exploits can get completely separate set of kmalloc caches that can't be shared with other users. The first converted users are alloc_msg() and memdup_user(). The hardening is enabled by CONFIG_SLAB_BUCKETS. - Extended kmalloc() alignment guarantees (Vlastimil Babka) For years now we have guaranteed natural alignment for power-of-two allocations, but nothing was defined for other sizes (in practice, we have two such buckets, kmalloc-96 and kmalloc-192). To avoid unnecessary padding in the rust layer due to its alignment rules, extend the guarantee so that the alignment is at least the largest power-of-two divisor of the requested size. This fits what rust needs, is a superset of the existing power-of-two guarantee, and does not in practice change the layout (and thus does not add overhead due to padding) of the kmalloc-96 and kmalloc-192 caches, unless slab debugging is enabled for them. - Cleanups and non-critical fixups (Chengming Zhou, Suren Baghdasaryan, Matthew Willcox, Alex Shi, Vlastimil Babka) Various tweaks related to the new alloc profiling code, folio conversion, debugging and more leftovers after SLAB.

tracing: Trivial updates for 6.11 - Set rtla/osnoise default threshold to 1us from 5us The 5us default was missing noise that people cared about. Changing it to 1us makes it work as expected. - Restructure how sched_switch prev_comm and next_comm was being saved. The prev_comm was being saved along with the other next fields, and the next_comm was being saved along with the other prev fields. This is just a cosmetic change. - Have the allocation of pid_list use GFP_NOWAIT instead of GFP_KERNEL. The allocation can happen in irq_work context, but luckily, the size was by default so large, it was never triggered. But in case it ever is, use the NOWAIT allocation in the interrupt context. - Fix some kernel doc errors. trace-v6.11
tracing/ring-buffer: Have persistent buffer across reboots
This allows for the tracing instance ring buffer to stay persistent across
reboots. The way this is done is by adding to the kernel command line:
trace_instance=boot_map@0x285400000:12M
This will reserve 12 megabytes at the address 0x285400000, and then map
the tracing instance "boot_map" ring buffer to that memory. This will
appear as a normal instance in the tracefs system:
/sys/kernel/tracing/instances/boot_map
A user could enable tracing in that instance, and on reboot or kernel
crash, if the memory is not wiped by the firmware, it will recreate the
trace in that instance. For example, if one was debugging a shutdown of a
kernel reboot:
# cd /sys/kernel/tracing
# echo function > instances/boot_map/current_tracer
# reboot
[..]
# cd /sys/kernel/tracing
# tail instances/boot_map/trace

swapper/0-1 [000] d..1. 164.549822: acpi_os_write_port <-acpi_reboot
On reboot, the buffer is examined to make sure it is valid. The validation
check even steps through every event to make sure the meta data of the
event is correct. If any test fails, it will simply reset the buffer, and
the buffer will be empty on boot.

Performance events changes for v6.11: - Intel PT support enhancements & fixes - Fix leaked SIGTRAP events - Improve and fix the Intel uncore driver - Add support for Intel HBM and CXL uncore counters - Add Intel Lake and Arrow Lake support - AMD uncore driver fixes - Make SIGTRAP and __perf_pending_irq() work on RT - Micro-optimizations - Misc cleanups and fixes Thanks, Ingo
Networking changes for 6.11. Not much excitement - a handful of large patchsets (devmem among them) did not make it in time. Core & protocols
Bootconfig updates for v6.11: - Remove duplicate included header file linux/bootconfig.h from lib/bootconfig.c. This is a cleanup, no behavior change. bootconfig-v6.11
Probes updates for v6.11: Uprobes: - x86/shstk: Make return uprobe work with shadow stack. - Add uretprobe syscall which speeds up the uretprobe 10-30% faster. This syscall is automatically used from user-space trampolines which are generated by the uretprobe. If this syscall is used by normal user program, it will cause SIGILL. Note that this is currently only implemented on x86_64. (This also has 2 fixes for adjusting the syscall number to avoid conflict with new *attrat syscalls.) - uprobes/perf: fix user stack traces in the presence of pending uretprobe. This corrects the uretprobe's trampoline address in the stacktrace with correct return address. - selftests/x86: Add a return uprobe with shadow stack test. - selftests/bpf: Add uretprobe syscall related tests. . test case for register integrity check. . test case with register changing case. . test case for uretprobe syscall without uprobes (expected to be failed). . test case for uretprobe with shadow stack. - selftests/bpf: add test validating uprobe/uretprobe stack traces - MAINTAINERS: Add uprobes entry. This does not specify the tree but to clarify who maintains and reviews the uprobes. Kprobes: - tracing/kprobes: Test case cleanups. Replace redundant WARN_ON_ONCE() + pr_warn() with WARN_ONCE() and remove unnecessary code from selftest. - tracing/kprobes: Add symbol counting check when module loads. This checks the uniqueness of the probed symbol on modules. The same check has already done for kernel symbols. (This also has a fix for build error with CONFIG_MODULES=n) Cleanup: - Add MODULE_DESCRIPTION() macros for fprobe and kprobe examples. probes-v6.11

Note: I have update the capabilities in my signing key. I don't think
anything changes on your side, but thought I'd mention it for good
would probably solve any unforeseen issues.
sysctl changes for 6.11-rc1
Summary
* Remove "->procname == NULL" check when iterating through sysctl table arrays
Removing sentinels in ctl_table arrays reduces the build time size and
runtime memory consumed by ~64 bytes per array. With all ctl_table
sentinels gone, the additional check for ->procname == NULL that worked in
tandem with the ARRAY_SIZE to calculate the size of the ctl_table arrays is
no longer needed and has been removed. The sysctl register functions now
returns an error if a sentinel is used.
* Preparation patches for sysctl constification
Constifying ctl_table structs prevents the modification of proc_handler
function pointers as they would reside in .rodata. The ctl_table arguments
in sysctl utility functions are const qualified in preparation for a future
treewide proc_handler argument constification commit.
* Misc fixes
Increase robustness of set_ownership by providing sane default ownership
values in case the callee doesn't set them. Bound check proc_dou8vec_minmax
to avoid loading buggy modules and give sysctl testing module a name to
avoid compiler complaints.
Testing
* This got push to linux-next in v6.10-rc2, so it has had more than a month
of testing

Here is the Smack pull request for v6.11. There are 2 patches. Both address network labeling issues. Both have been in the next branch and pass all tests. Two fixes for Smack networking by Konstantin Andreev.
NOTE: I couldn't get git-request-pull to generate the correct diffstat. The
diffstat at the end is generated against the merged base and should
match the diff when sched_ext-for-6.11 is pulled after tip/sched/core
and bpf/for-next.
sched_ext: Initial pull request for v6.11
This is the initial pull request of sched_ext. The v7 patchset
(https://lkml.kernel.org/r/20240618212056.2833381-1-tj@kernel.org) is
applied on top of tip/sched/core + bpf/for-next as of Jun 18th.
tip/sched/core 793a62823d1c ("sched/core: Drop spinlocks on contention iff kernel is preemptible")
bpf/for-next f6afdaf72af7 ("Merge branch 'bpf-support-resilient-split-btf'")
Since then, the following changes:
- cpuperf support which was a part of the v6 patchset was posted separately
and then applied after reviews.
- tip/sched/core is pulled into resolve the conflicts between
e83edbf88f18 ("sched: Add sched_class->reweight_task()")
d32960528702 ("sched/fair: set_load_weight() must also call reweight_task() for SCHED_IDLE tasks")
The former makes reweight_task() a sched_class operation for sched_ext
while the latter fixed a bug around idle weight handling in the same area.
The conflicts are not trivial although not that complicated either.
- Improve integration with sched core.
- DSQ iterator which was a part of the v6 patchset was posted separately.
The iterator itself was applied after a couple revisions. The associated
selective consumption kfunc can use further improvements and is still
being worked on.
- The BPF scheduler couldn't directly dispatch to the local DSQ of another
CPU using a SCX_DSQ_LOCAL_ON verdict. This caused difficulties around
handling non-wakeup enqueues. Updated so that SCX_DSQ_LOCAL_ON can be used
in the enqueue path too.
- Various fixes and improvements.
As the branch is based on top of tip/sched/core + bpf/for-next, please merge
after both are applied.
kcsan: Add __data_racy documentation and module description This series contains on commit that improves the documentation for the new __data_racy type qualifier to the data_race() macro's kernel-doc header and to the LKMM's access-marking documentation.
Please please pull the latest nolibc changes from:
nolibc updates for v6.11
oFix selftest printf format mismatch in expect_str_buf_eq().
oStop using brk() and sbrk() when testing against musl, which
implements these two functions with ENOMEM.
oMake tests use -Werror to force failure on compiler warnings.
oAdd limits for the {u,}intmax_t, ulong and {u,}llong types.
oImplement strtol() and friends.
oAdd facility to skip nolibc-specific tests when running against
non-nolibc libraries.
oImplement strerror().
oAlso use strerror() on nolibc when running kselftests.
asm-generic updates for 6.11 Most of this is part of my ongoing work to clean up the system call tables. In this bit, all of the newer architectures are converted to use the machine readable syscall.tbl format instead in place of complex macros in include/uapi/asm-generic/unistd.h. This follows an earlier series that fixed various API mismatches and in turn is used as the base for planned simplifications. The other two patches are dead code removal and a warning fix.
Here are the four pull requests for the soc tree.=20
We have again just over 1000 non-merge changesets in the SoC tree, from
62 pull requests plus some individual patches. About 80% of this is arm6=
4,
the rest is arm32 and riscv.=20
Not much sticks out in the contents, there are three new SoCs and a
fairly large number of new machines, but it's spread out over a lot
of platforms, with rockchip and ti having more than usual.

Hi,
please pull the changes described below. The hilights are new logic
behind background block group reclaim, automatic removal of qgroup
after removing a subvolume and new 'rescue=' mount options. The rest is
optimizations, cleanups and refactoring.
There's a merge conflict caused by the latency fixes from last week in
extent_map.c:btrfs_scan_inode(), related commits 4e660ca3a98d931809734
and b3ebb9b7e92a928344a. Resolved in branch for-6.11-merged and that's
been in linux-next for a few days.
User visible features:
- dynamic block group reclaim:
- tunable framework to avoid situations where eager data allocations
prevent creating new metadata chunks due to lack of unallocated
space
- reuse sysfs knob bg_reclaim_threshold (otherwise used only in zoned
mode) for a fixed value threshold
- new on/off sysfs knob "dynamic_reclaim" calculating the value based
on heuristics, aiming to keep spare working space for relocating
chunks but not to needlessly relocate partially utilized block
groups or reclaim newly allocated ones
- stats are exported in sysfs per block group type, files "reclaim_*"
- this may increase IO load at unexpected times but the corner case of
no allocatable block groups is known to be worse
- automatically remove qgroup of deleted subvolumes
- adjust qgroup removal conditions, make sure all related subvolume
data are already removed, or return EBUSY, also take into account
setting of sysfs drop_subtree_threshold
- also works in squota mode
- mount option updates: new modes of 'rescue=' that allow to mount (as
read-only) images that could have been partially converted by
user space tools
- ignoremetacsums - invalid metadata checksums are ignored
- ignoresuperflags - super block flags that track conversion in
progress (like UUID or checksums)
Core:
- size of struct btrfs_inode is now below 1024 (on a release config),
improved memory packing and other secondary effects
- switch tracking of open inodes from rb-tree to xarray, minor
performance improvement
- reduce number of empty transaction commits when there are no dirty
data/metadata
- memory allocation optimizations (reduced numbers, reordering out of
critical sections)
- extent map structure optimizations and refactoring, more sanity checks
- more subpage in zoned mode preparations or fixes
- general snapshot code cleanups, improvements and documentation
- tree-checker updates: more file extent ram_bytes fixes, continued
- raid-stripe-tree update (not backward compatible):
- remove extent encoding field from the structure, can be inferred
from other information
- requires btrfs-progs 6.9.1 or newer
- cleanups and refactoring
- error message updates
- error handling improvements
- return type and parameter cleanups and improvements
please pull the x86/bugs lineup for v6.11-rc1. Thx. --- - Add a spectre_bhi=vmexit mitigation option aimed at cloud environments - Remove duplicated Spectre cmdline option documentation - Add separate macro definitions for syscall handlers which do not return in order to address objtool warnings
Note, this set includes a patch touching drivers/md/md-cluster.c, acked by the md-cluster developers, making use of the new DLM_LSFL_SOFTIRQ_SAFE flag. Overall, changes include: - New flag DLM_LSFL_SOFTIRQ_SAFE can be set by code using dlm to indicate callbacks can be run from softirq. - Change md-cluster to set DLM_LSFL_SOFTIRQ_SAFE. - Clean up for previous changes, e.g. unused code and parameters. - Remove custom pre-allocation of rsb structs which is unnecessary with kmem caches. - Change idr to xarray for lkb structs in use. - Change idr to xarray for rsb structs being recovered. - Change outdated naming related to internal rsb states. - Fix some incorrect add/remove of rsb on scan list. - Use rcu to free rsb structs. Thanks, Dave

NFSD 6.11 Release Notes This is a light release containing optimizations, code clean-ups, and minor bug fixes. This development cycle focused on work outside of upstream kernel development: 1. Continuing to build upstream CI for NFSD based on kdevops 2. Continuing to focus on the quality of NFSD in LTS kernels 3. Participation in IETF nfsv4 WG discussions about NFSv4 ACLs, directory delegation, and NFSv4.2 COPY offload Notable features in v6.11 that were not pulled through the NFSD tree include NFS server-side support for the new pNFS NVMe layout type [RFC9561]. Functional testing for pNFS block layouts like this one has been introduced to our kdevops CI harness. Work on improving the resolution of file attribute time stamps in local filesystems is also ongoing tree-wide. As always I am grateful to NFSD contributors, reviewers, testers, and bug reporters who participated during this cycle.
spi: Updates for v6.11 There's some quite exciting core work in this release, we've got the beginnings of support for hardware initiated transfers which is itself independently useful for optimising fast paths in existing drivers. We also have a rework of the DMA mapping which allows finer grained decisions about DMA mapping messages and also helps remove some bodges that we'd had. Otherwise it's a fairly quiet release, a few new drivers and features for existing drivers, together with various cleanups and DT binding conversions. One regmap SPI fix made it's way in here too which I should probably have sent as a regmap fix instead. - Support for pre-optimising messages, reducing the overhead for messages that are repeatedly used (eg, reading the interrupt status from a device). This will also be used for hardware initiated transfers in future. - A reworking of how DMA mapping is done, introducing a new helper and allowing the DMA mapping decision to be done per transfer instead of per message. - Support for Atmel SAMA7D64, Freescale LX2160A DSPI and WCH CH341A.
regmap: Updates for v6.11 There's one new feature here, a regmap_multi_reg_read() matching the existing write function which has some IIO users coming. This allows atomic reads from multiple registers without the need to wrap a higher level lock in the client driver just for regmap (which already has locks anyway). We also have one fix for the KUnit tests, and a bunch of cleanups.
regulator: Updates for v6.11 This s a very quiet release for the regulator API, we have a few new devices (most of which are just ID updates) and one new fairly specialist core feature for use in interrupt context. - An API allowing lockless enable/disable for regulators acquired in exclusive mode, for use in interrupt contexts. - A rewrite of the MedaTek DVFSRC regulator driver which apparently never worked. - Support for Mediaktek MT6312, Qualcomm QCA6390 and WCN7850, Renesas RZ/G2L USB VBUS regulator and ST Microelectronics STM32MP13.
please pull a single x86 build improvement for v6.11-rc1. Thx. --- - Make sure insn support detection uses the proper compiler flag in bi-arch builds
USB-serial updates for 6.11-rc1 Here are the USB-serial updates for 6.11-rc1, including: - add missing module descriptions - add flexible array annotation in garmin_gps Included are also various clean ups. All have been in linux-next with no reported issues.
Locking changes for v6.11: - Jump label fixes, including a perf events fix that originally manifested as jump label failures, but was a serialization bug at the usage site. - Mark down_write*() helpers as __always_inline, to improve WCHAN debuggability. - Misc cleanups and fixes. Thanks, Ingo
Hi, please pull the following conversions of the one-element to flexible arrays. Thanks.
please pull the x86/core lineup for v6.11-rc1. Basically your own patch. :-P Thx. --- - Cleanup the 8-byte getuser() asm case
please pull the x86 confidential computing lineup for v6.11-rc1.
Thx.

- Unrelated x86/cc changes queued here to avoid ugly cross-merges and
conflicts:
- Carve out CPU hotplug function declarations into a separate header
with the goal to be able to use the lockdep assertions in a more
flexible manner
- As a result, refactor cacheinfo code after carving out a function
to return the cache ID associated with a given cache level
- Cleanups
- Add support to be able to kexec TDX guests. For that
- Expand ACPI MADT CPU offlining support
- Add machinery to prepare CoCo guests memory before kexec-ing into a new
kernel
- Cleanup, readjust and massage related code
please pull the x86/boot lineup for v6.11-rc1. Thx. --- - Add a check to warn when cmdline parsing happens before the final cmdline string has been built and thus arguments can get lost - Code cleanups and simplifications
please pull updates to x86/alternatives for v6.11-rc1. Thx. --- - This is basically PeterZ's idea to nest the alternative macros to avoid the need to "spell out" the number of alternates in an ALTERNATIVE_n() macro and thus have an ever-increasing complexity in those definitions. For ease of bisection, the old macros are converted to the new, nested variants in a step-by-step manner so that in case an issue is encountered during testing, one can pinpoint the place where it fails easier. Because debugging alternatives is a serious pain.
please pull ras/core for v6.11-rc1. Thx. --- - A cleanup and a correction to the error injection driver to inject a MCA_MISC value only when one has actually been supplied by the user

The majority of added lines are two new modules: the GPIO virtual consumer module that improves our ability to add automated tests for the kernel API and the "sloppy" logic analyzer module that uses the GPIO API to implement a coarse-grained debugging tool for useful for remote development. Other than that we have the usual assortment of various driver extensions, improvements to the core GPIO code, DT-bindings and other documentation updates as well as an extension to the interrupt simulator. Best Regards, Bartosz Golaszewski gpio updates for v6.11-rc1 GPIOLIB core: - rework kfifo handling rework in the character device code - improve the labeling of GPIOs requested as interrupts and show more info on interrupt-only GPIOs in debugfs - remove unused APIs - unexport interfaces that are only used from the core GPIO code - drop the return value from gpiochip_set_desc_names() as it cannot fail - move a string array definition out of a header and into a specific compilation unit - convert the last user of gpiochip_get_desc() other than GPIO core to using a safer alternative - use array_index_nospec() where applicable New drivers: - add a "virtual GPIO consumer" module that allows requesting GPIOs from actual hardware and driving tests of the in-kernel GPIO API from user-space over debugfs - add a GPIO-based "sloppy" logic analyzer module useful for "first glance" debugging on remote boards Driver improvements: - add support for a new model to gpio-pca953x - lock GPIOs as interrupts in gpio-sim when the lines are requested as irqs via the simulator domain + some other minor improvements - improve error reporting in gpio-syscon - convert gpio-ath79 to using dynamic GPIO base and range - use pcibios_err_to_errno() for converting PCIBIOS error codes to errno vaues in gpio-amd8111 and gpio-rdc321x - allow building gpio-brcmstb for the BCM2835 architecture DT bindings: - convert DT bindings for lsi,zevio, mpc8xxx, and atmel to DT schema - document new properties for aspeed,gpio, fsl,qoriq-gpio and gpio-vf610 - document new compatibles for pca953x and fsl,qoriq-gpio Documentation: - document stricter behavior of the GPIO character device uAPI with regards to reconfiguring requested line without direction set - clarify the effect of the active-low flag on line values and edges - remove documentation for the legacy GPIO API in order to stop tempting people to use it - document the preference for using pread() for reading edge events in the sysfs API Other: - add an extended initializer to the interrupt simulator allowing to specify a number of callbacks callers can use to be notified about irqs being requested and released
Could you consider this pull request for 6.11-rc1? No outstanding new features have landed for this cycle so far. There are patches addressing folio conversions for compressed inodes: While large folio support for compressed data could work now, it remains disabled since the stress test could hang due to page migration in a few hours after enabling it. I need more time to investigate further before enabling this feature. Additionally, there are also some patches to clean up stream decompressors and tracepoints for simplicity. All commits have been tested and no potential merge conflict is observed. Thanks, Gao Xiang Changes since last update: - More folio conversions for compressed inodes; - Stream decompressor (LZMA/DEFLATE/ZSTD) cleanups; - Minor tracepoint cleanup.
Please git pull the following tag: xen: branch for v6.11-rc1 It contains the following patches: - some trivial cleanups - a fix for the Xen timer - a patch for adding boot time selectable debug capability to the Xen multicall handling - two fixes for the recently added Xen irqfd handling Thanks. Juergen
cgroup: Changes for v6.11 - Added Michal Koutný as a maintainer. - Counters in pids.events were behaving inconsistently. pids.events made properly hierarchical and pids.events.local added. - misc.peak and misc.events.local added. - cpuset remote partition creation and cpuset.cpus.exclusive handling improved. - Code cleanups, non-critical fixes, doc updates. - for-6.10-fixes is merged in to receive two non-critical fixes that didn't trigger pull.
workqueue: Changes for v6.11
- Lai fixed a bug where CPU hotplug and workqueue attribute changes race
leaving some workqueues not fully updated. This involved refactoring and
changing how online CPUs are tracked. The resulting code is cleaner.
- Workqueue watchdog touch operation was causing too much cacheline
contention on very large machines. Nicholas improved scalabililty by
avoiding unnecessary global updates.
- Code cleanups and minor rescuer behavior improvement.
- The last commit 58629d4871e8 ("workqueue: Always queue work items to the
newest PWQ for order workqueues") is a cherry-picked straggler commit from
for-6.10-fixes, a fix for a bug which may not actually trigger.
Unfortunately, maybe because for-6.10-fixes was branched off at a
different point from for-6.11, I couldn't persuade git request-pull to
generate clean diffstat if pulled into for-6.11.

Hi Linus, Thanks, TzungBi ------ chrome platform firmware changes for 6.11 * Minor cleanups.
bcachefs changes for 6.11-rc1 - Metadata version 1.8: Stripe sectors accounting, BCH_DATA_unstriped This splits out the accounting of dirty sectors and stripe sectors in alloc keys; this lets us see stripe buckets that still have unstriped data in them. This is needed for ensuring that erasure coding is working correctly, as well as completing stripe creation after a crash. - Metadata version 1.9: Disk accounting rewrite The previous disk accounting scheme relied heavily on percpu counters that were also sharded by outstanding journal buffer; it was fast but not extensible or scalable, and meant that all accounting counters were recorded in every journal entry. The new disk accounting scheme stores accounting as normal btree keys; updates are deltas until they are flushed by the btree write buffer. This means we have no practical limit on the number of counters, and a new tagged union format that's easy to extend. We now have counters for compression type/ratio, per-snapshot-id usage, per-btree-id usage, and pending rebalance work. - Self healing on read IO/checksum error data is now automatically rewritten if we get a read error and then a successful retry - Mount API conversion (thanks to Thomas Bertschinger) - Better lockdep coverage Previously, btree node locks were tracked individually by lockdep, like any other lock. But we may take _many_ btree node locks simultaneously, we easily blow through the limit of 48 locks that lockdep can track, leading to lockdep turning itself off. Tracking each btree node lock individually isn't really necessary since we have our own cycle detector for deadlock avoidance and centralized tracking of btree node locks, so we now have a single lockdep_map in btree_trans for "any btree nodes are locked". - some more small incremental work towards online check_allocations - lots more debugging improvements, fixes

Best regards Uwe pwm: Changes for v6.11-rc1 This contains the usual mix of fixes, cleanups, two new drivers and several dt binding updates. The fixes are for minor issues that are already old (4.11-rc1 and 3.9-rc1) and were found by code review and not during usage, so I didn't sent them for earlier inclusion. The changes to include/linux/mfd/stm32-timers.h and drivers/counter/stm32-timer-cnt.c are part of an immutable branch that will also be included in the mfd and counter PR.

Updates for the interrupt subsystem:
- Core:
- Provide a new mechanism to create interrupt domains. The existing
interfaces have already too many parameters and it's a pain to expand
any of this for new required functionality.
The new function takes a pointer to a data structure as argument. The
data structure combines all existing parameters and allows for easy
extension.
The first extension for this is to handle the instantiation of
generic interrupt chips at the core level and to allow drivers to
provide extra init/exit callbacks.
This is necessary to do the full interrupt chip initialization before
the new domain is published, so that concurrent usage sites won't see
a half initialized interrupt domain. Similar problems exist on
teardown.
This has turned out to be a real problem due to the deferred and
parallel probing which was added in recent years.
Handling this at the core level allows to remove quite some accrued
boilerplate code in existing drivers and avoids horrible workarounds
at the driver level.
- The usual small improvements all over the place
- MSI
- Switch ARM/ARM64 over to the modern per device MSI domains.
This simplifies the handling of platform MSI and wire to MSI
controllers and removes about 500 lines of legacy code.
Aside of that it paves the way for ARM/ARM64 to utilize the dynamic
allocation of PCI/MSI interrupts and to support the upcoming non
standard IMS (Interrupt Message Store) mechanism on PCIe devices
- Drivers
- Add support for LAN966x OIC and RZ/Five SoC
- Split the STM ExtI driver into a microcontroller and a SMP version to
allow building the latter as a module for multi-platform kernels.
- Enable MSI support for Armada 370XP on platforms which do not support
IPIs.
- The usual small fixes and enhancements all over the place.

people/daniel.lezcano/linux into timers/core
Updates for timers, timekeeping and related functionality:
- Core:
- Make the takeover of a hrtimer based broadcast timer reliable during
CPU hot-unplug. The current implementation suffers from a race which
can lead to broadcast timer starvation in the worst case.
- VDSO related cleanups and simplifications
- Small cleanups and enhancements all over the place
=20
- PTP:
- Replace the architecture specific base clock to clocksource, e.g. ART
to TSC, conversion function with generic functionality to avoid
exposing such internals to drivers and convert all existing drivers
over. This also allows to provide functionality which converts the
other way round in the core code based on the same parameter set.
- Provide a function to convert CLOCK_REALTIME to the base clock to
support the upcoming PPS output driver on Intel platforms.
- Drivers:
- A set of Device Tree bindings for new hardware
- Cleanups and enhancements all over the place

ll_on_cpu()
A small set of SMP/CPU hotplug updates:

This avoids that drivers like the Intel uncore performance counter have
to transfer the assignement of handling the per package uncore events
for every CPU in a package, which is a considerable speedup on larger
systems.
- Add a missing destroy_work_on_stack() invocation in smp_call_on_cpu()
to prevent debug objects to emit a false positive warning when the
stack is freed.
- Small cleanups in comments and a str_plural() conversion

Here's the vDSO getrandom() work we've been discussing for the last few weeks. Thank you very much for your input on this and for working with me to get this where it is. I'm happy with the set of compromises, and I think this wound up in a decent place. A blurb for the merge message: This is a short series adding getrandom() support to the vDSO. First, it adds a new kind of mapping to mmap(2), MAP_DROPPABLE, which lets the kernel zero out pages anytime under memory pressure, which enables allocating memory that never gets swapped to disk but also doesn't count as being mlocked. Then, the vDSO implementation of getrandom() is introduced in a generic manner and hooked into random.c. Next, this is implemented on x86. (Also, though it's not ready for this pull, somebody has begun an arm64 implementation already.) Finally, two vDSO selftests are added. Each version of this series has been in linux-next for a little bit, and there are no major reported issues, though there may be a trivial merge conflict. Thanks, Jason Random number generator updates for Linux 6.11-rc1.

This litmus test manages to violate this assumption because the spin_is_locked() follows the same process's spin_unlock(). This series fixes this bug, reorganizes and optimizes the lock.cat model, and updates documentation.
Hi Wolfram,
Not a massive pull request. The majority of changes relate to the
naming convention updates. Other than that, the holiday period
has given us some slack in the number of patches queued for this
pull request.
There is still one pending documentation fix required for an
issue reported by Stephen that I haven't noticed. I need to add
the documentation check to my workflow. If you don't have the
bandwidth, I can take care of it.
I also have a pending patch for a v2 pull request from Hans de
Goede ("i2c: i801: Use a different adapter name for IDF
adapters") that is waiting for precedence.
I wish you a great rest of the weekend,
Andi
This release includes significant updates, with the primary
change being the renaming from "master/slave" to
"controller/target" to adhere to I2C v7 and SMBus 3.2 standards.
New Support:
- Added support for Intel Arrow Lake-H.
- Added I2C support in the Arioha SoC by linking the Mediatek
I2C controller.
Cleanups:
- Added the MODULE_DESCRIPTION() macro, resolving a modpost
warning in the ALi 1563 Southbridge driver.
- Constified the regmap_config declaration in the i2c-designware
driver.
- Improved the coding style in the Renesas R-Car driver by
removing unnecessary semicolons after brackets.
General improvements:
- In the OMAP device, replaced NOIRQ_SYSTEM_SLEEP_PM_OPS with
RUNTIME_PM_OPS to enable waking up the controller during
suspend() before suspend_noirq() kicks in.
- Improved logging in the Xilinx driver.
- Added a warning (WARN()) in the Renesas R-Car driver for
spurious interrupts.
DTS Changes:
- Removed address-cell and size-cell from the Atmel at91sam,
nVidia Tegra 20, and Samsung S3c2410 devices.
- Fixed Texas Instruments OMAP4 I2C controller to comply with
the i2c-controller.yaml schema.
- Improved indentation in DTS examples for several I2C devices.
- Converted the NXP LPC1788 binding to the dt-schema.
- Added documentation for the compatible string
thead,th1520-i2c.
- Added the "power-domains" property for the Meson I2C driver.
There's a trivial conflict between "misc" and "vmx" in kvm-x86-ops.h, they both delete ops that happen to be _right_ next to each other. Otherwise, should apply cleanly.

/* Summary */
This contains work to make it possible to derive namespace file descriptors
from pidfd file descriptors.
Right now it is already possible to use a pidfd with setns() to atomically
change multiple namespaces at the same time. In other words, it is possible to
switch to the namespace context of a process using a pidfd. There is no need to
first open namespace file descriptors via procfs.
The work included here is an extension of these abilities by allowing to open
namespace file descriptors using a pidfd. This means it is now possible to
interact with namespaces without ever touching procfs.
To this end a new set of ioctls() on pidfds is introduced covering all
supported namespace types.

vfs-6.11.pidfs
/* Summary */
This adds ioctls allowing to translate PIDs between PID namespaces.
The motivating use-case comes from LXCFS which is a tiny fuse filesystem used
to virtualize various aspects of procfs. LXCFS is run on the host. The files
and directories it creates can be bind-mounted by e.g. a container at startup
and mounted over the various procfs files the container wishes to have
virtualized.
When e.g. a read request for uptime is received, LXCFS will receive the pid of
the reader. In order to virtualize the corresponding read, LXCFS needs to know
the pid of the init process of the reader's pid namespace.
In order to do this, LXCFS first needs to fork() two helper processes. The
first helper process setns() to the readers pid namespace. The second helper
process is needed to create a process that is a proper member of the pid
namespace.
The second helper process then creates a ucred message with ucred.pid set to 1
and sends it back to LXCFS. The kernel will translate the ucred.pid field to
the corresponding pid number in LXCFS's pid namespace. This way LXCFS can learn
the init pid number of the reader's pid namespace and can go on to virtualize.
Since these two forks() are costly LXCFS maintains an init pid cache that
caches a given pid for a fixed amount of time. The cache is pruned during new
read requests. However, even with the cache the hit of the two forks() is
singificant when a very large number of containers are running.
So this adds a simple set of ioctls that let's a caller translate PIDs from and
into a given PID namespace. This significantly improves performance with a very
simple change.
To protect against races pidfds can be used to check whether the process is
still valid.

/* Summary */ This contains work to extend the abilities of listmount() and statmount() and various fixes and cleanups. Features: - Allow iterating through mounts via listmount() from newest to oldest. This makes it possible for mount(8) to keep iterating the mount table in reverse order so it gets newest mounts first. - Relax permissions on listmount() and statmount(). It's not necessary to have capabilities in the initial namespace. It's sufficient to have capabilities in the owning namespace of the mount namespace we're located in to list unreachable mounts in that namespace. - Extend both listmount() and statmount() to list and stat mounts in foreign mount namespaces. Currently the only way to iterate over mount entries in mount namespaces that aren't in the caller's mount namespace is by crawling through /proc in order to find /proc/<pid>/mountinfo for the relevant mount namespace. This is both very clumsy and hugely inefficient. So extend struct mnt_id_req with a new member that allows to specify the mount namespace id of the mount namespace we want to look at. Luckily internally we already have most of the infrastructure for this so we just need to expose it to userspace. Give userspace a way to retrieve the id of a mount namespace via statmount() and through a new nsfs ioctl() on mount namespace file descriptor. This comes with appropriate selftests. - Expose mount options through statmount(). Currently if userspace wants to get mount options for a mount and with statmount(), they still have to open /proc/<pid>/mountinfo to parse mount options. Simply the information through statmount() directly. Afterwards it's possible to only rely on statmount() and listmount() to retrieve all and more information than /proc/<pid>/mountinfo provides. This comes with appropriate selftests. Fixes: - Avoid copying to userspace under the namespace semaphore in listmount. Cleanups: - Simplify the error handling in listmount by relying on our newly added cleanup infrastructure. - Refuse invalid mount ids early for both listmount and statmount. /* Testing */ clang: Debian clang version 16.0.6 (26) gcc: (Debian 13.2.0-24) All patches are based on v6.10-rc1 and have been sitting in linux-next.

/* Summary */ This contains work to allow restricting access to /proc/<pid>/mem. Over the years various exploits started abusing /proc/<pid>/mem (cf. [1] and [2]). Specifically [2] is interesting as it installed an arbitrary payload from noexec storage into a running process and then executed it. That payload itself included an ELF loader to run arbitrary code off of noexec storage. The biggest problem is that /proc/<pid>/mem ignores page permissions by using FOLL_FORCE which was discussed several times on- and off-list. Unfortunately there are various use-cases using /proc/<pid>/mem making it impossible to just turn it off. They at least include PTRACE_POKEDATA and the seccomp notifier which is used to emulate system calls. So give userspace a way to restrict access to /proc/<pid>/mem via kernel command line options. Setting them to "all" restricts access for all processes while "ptracer" will allow access to ptracers: (1) Restrict the use of FOLL_FORCE via proc_mem.restrict_foll_force (2) Restrict opening /proc/<pid>/mem for reading. (3) Restrict opening /proc/<pid>/mem for writing. (4) Restrict writing to /proc/<pid>/mem. --- The level of fine-grained management isn't my favorite as it requires distributions to have some level of knowledge around the implications of FOLL_FORCE and /proc/<pid>/mem access in general. But the use-cases where /proc/<pid>/mem access is needed do already imply a sophisticated knowledge around its implications. Especially when it comes to the seccomp notifier and gdb to inspect or emulate process state. So that ultimately swayed me to accept this. If we need something simpler I'm all ears. /* Testing */ clang: Debian clang version 16.0.6 (26) gcc: (Debian 13.2.0-24) All patches are based on v6.10-rc1 and have been sitting in linux-next.

/* Summary */
This contains smaller performance improvements to inodes and dentries:
# inode:
- Add rcu based inode lookup variants. They avoid one inode hash lock acquire
in the common case thereby significantly reducing contention. We already
support RCU-based operations but didn't take advantage of them during inode
insertion.
Callers of iget_locked() get the improvement without any code changes.
Callers that need a custom callback can switch to iget5_locked_rcu() as e.g.,
did btrfs.
With 20 threads each walking a dedicated 1000 dirs * 1000 files directory
tree to stat(2) on a 32 core + 24GB ram vm:
before: 3.54s user 892.30s system 1966% cpu 45.549 total
after: 3.28s user 738.66s system 1955% cpu 37.932 total (-16.7%)
Long-term we should pick up the effort to introduce more fine-grained locking
and possibly improve on the currently used hash implementation.
- Start zeroing i_state in inode_init_always() instead of doing it in
individual filesystems. This allows us to remove an unneeded lock acquire in
new_inode() and not burden individual filesystems with this.
dcache:
- Move d_lockref out of the area used by RCU lookup to avoid cacheline ping
poing because the embedded name is sharing a cacheline with d_lockref.
- Fix dentry size on 32bit with CONFIG_SMP=y so it does actually end up with
128 bytes in total.

This causes a merge conflict with fs/bcachefs/fs.c. The gist is that
inode->i_state initialization in __bch2_new_inode() isn't needed anymore after
this is merged and that line needs to be deleted from that function.

/* Summary */ This contains work for the mount api: - Add a generic helper to parse uid and gid mount options. Currently we open-code the same logic in various filesystems which is error prone. Especially since the verification of uid and gid mount options is a sensitive operation in the face of idmappings. Add a generic helper and convert all filesystems over to it. Make sure that filesystems that are mountable in unprivileged containers verify that the specified uid and gid can be represented in the owning namespace of the filesystem. - Convert hostfs to the new mount api. /* Testing */ clang: Debian clang version 16.0.6 (26) gcc: (Debian 13.2.0-24) All patches are based on v6.10-rc1 and have been sitting in linux-next.

This contains work to remove almost all remaining users of PG_error from
filesystems and filesystem helper libraries. An additional patch will be coming
in via the jfs tree which tests the PG_error bit. Afterwards nothing will be
testing it anymore and it's safe to remove all places which set or clear the
PG_error bit. The goal is to fully remove PG_error by the next merge window.

There's one merge conflict in fs/nsfs/symlink.c
After conflict resolution the function should look like this:
static int nfs_symlink_filler(struct file *file, struct folio *folio)
{
struct inode *inode = folio->mapping->host;
int error;
error = NFS_PROTO(inode)->readlink(inode, &folio->page, 0, PAGE_SIZE);

/* Summary */
Features:
- Support passing NULL along AT_EMPTY_PATH for statx(). NULL paths with any
flag value other than AT_EMPTY_PATH go the usual route and end up with
-EFAULT to retain compatibility (Rust is abusing calls of the sort to detect
availability of statx).
This avoids path lookup code, lockref management, memory allocation and in
case of NULL path userspace memory access (which can be quite expensive with
SMAP on x86_64).
- Don't block i_writecount during exec. Remove the deny_write_access()
mechanism for executables.
- Relax open_by_handle_at() permissions in specific cases where we can prove
that the caller had sufficient privileges to open a file.
- Switch timespec64 fields in struct inode to discrete integers freeing up 4
bytes.
Fixes:
- Fix false positive circular locking warning in hfsplus.
- Initialize hfs_inode_info after hfs_alloc_inode() in hfs.
- Avoid accidental overflows in vfs_fallocate().
- Don't interrupt fallocate with EINTR in tmpfs to avoid constantly restarting
shmem_fallocate().
- Add missing quote in comment in fs/readdir.
Cleanups:
- Don't assign and test in an if statement in mqueue. Move the assignment out
of the if statement.
- Reflow the logic in may_create_in_sticky().
- Remove the usage of the deprecated ida_simple_xx() API from procfs.
- Reject FSCONFIG_CMD_CREATE_EXCL requets that depend on the new mount api early.
- Rename variables in copy_tree() to make it easier to understand.
- Replace WARN(down_read_trylock, ...) abuse with proper asserts in various
places in the VFS.
- Get rid of user_path_at_empty() and drop the empty argument from
getname_flags().
- Check for error while copying and no path in one branch in getname_flags().
- Avoid redundant smp_mb() for THP handling in do_dentry_open().
- Rename parent_ino to d_parent_ino and make it use RCU.
- Remove unused header include in fs/readdir.
- Export in_group_capable() helper and switch f2fs and fuse over to it instead
of open-coding the logic in both places.

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org> I'm sending this early as this is the initial pull-request for a new driver subsystem living under drivers/power/sequencing/. I'll try to be brief here and allow myself to link the cover letter from the last time the series was sent in its entirety[1] (as opposed to smaller chunks targetting specific maintainers) for a very detailed description of the problem and the solution. I'll just stick to the key points below. This has been in development since last year's Linux Plumbers Conference and was inspired by the need to enable support upstream for Bluetooth/WLAN chips on Qualcomm platforms. The main problem we're fixing is powering up devices which are represented as separate objects in the kernel (binding to different drivers) but which share parts of the power-up sequence and thus need some kind of a mediator who knows the possible interactions and can assure they don't interfere with neither device's bring up. An example of such an inter-driver interaction is the WCN family of BT/WLAN chips from Qualcomm of which some models require the user to observe a certain delay between driving the bt-enable and wlan-enable GPIOs. This is not a new problem but up to this point all attempts at addressing it ended up hitting one wall or another and being dropped. The main obstacle was the fact that most these attempts tried to introduce the concept of a "power sequence" into the device-tree bindings which breaks the main DT rule: describe the hardware, not its behavior. The solution I proposed focuses on making the power sequencer drivers interpret the actual HW description flexibly. More details on that are in the linked cover letter. The second problem fixed here is powering up PCI devices before they are detected on the bus. This is achieved by creating special platform devices for device-tree nodes describing hard-wired PCI devices which bind to the so-called PCI power control drivers which enable required resources and trigger a bus rescan once the controlled device is up then setup the correct devlink hierarchy for power-management. By combining the two new frameworks we implemented the power sequencing PCI power control driver which is capable of powering up the WLAN modules of the QCom WCN family of chipsets. All this has spent a significant amount of time in linux-next and enabled WLAN/BT support on several Qualcomm platforms. To further prove that this is useful and needed: right after this was picked up into next, I was sent a series using the subsystem for a similar use-case on Amlogic platforms[2]. This PR contains the core power sequencing framework, the first driver, PCI changes using the pwrseq library (blessed by Bjorn Helgaas) and some fixes that came later. You'll also see the pwrseq core pulled into the Bluetooth tree to satisfy the build-time dependency on power sequencing in the hci_qca driver which uses the same power sequence provider as the PCI pwrctl driver added in this PR. More changes that don't have build-time dependencies on pwrseq are scattered across three other maintainer trees: there will be DT bindings in the regulator and wireless trees and DTS changes in the arm64 tree. Please consider pulling for v6.11. Best Regards, Bartosz Golaszewski [1] https://lore.kernel.org/all/20240528-pwrseq-v8-0-d354d52b763c@linaro.org/ [2] https://lore.kernel.org/lkml/20240705-pwrseq-v1-0-31829b47fc72@amlogic.com/ pwrseq updates for v6.11-rc1 - add the pwrseq core framework - add the first power sequencing driver: pwrseq-qcom-wcn - add power control (pwrctl) changes to PCI core - add the first PCI pwrctl power sequencing driver
I'm about to go on holiday for two weeks, so here's an early pull
request for 6.11. The biggest part is the virtual CPU hotplug that
touches ACPI, irqchip. We also have some GICv3 optimisation for
pseudo-NMIs that has been queued via the arm64 tree. Otherwise the usual
perf updates, kselftest, various small cleanups. There's a minor
conflict currently in -next with the kvmarm tree but it's trivial (in
arch/arm64/include/asm/esr.h).
I'll check emails occasionally during the merging window but if there's
anything urgent, Will can take over.
Thanks.
arm64 updates for 6.11:
* Virtual CPU hotplug support for arm64 ACPI systems
* cpufeature infrastructure cleanups and making the FEAT_ECBHB ID bits
visible to guests
* CPU errata: expand the speculative SSBS workaround to more CPUs
* arm64 ACPI:
- acpi=nospcr option to disable SPCR as default console for arm64
- Move some ACPI code (cpuidle, FFH) to drivers/acpi/arm64/
* GICv3, use compile-time PMR values: optimise the way regular IRQs are
masked/unmasked when GICv3 pseudo-NMIs are used, removing the need for
a static key in fast paths by using a priority value chosen
dynamically at boot time
* arm64 perf updates:
- Rework of the IMX PMU driver to enable support for I.MX95
- Enable support for tertiary match groups in the CMN PMU driver
- Initial refactoring of the CPU PMU code to prepare for the fixed
instruction counter introduced by Arm v9.4
- Add missing PMU driver MODULE_DESCRIPTION() strings
- Hook up DT compatibles for recent CPU PMUs
* arm64 kselftest updates:
- Kernel mode NEON fp-stress
- Cleanups, spelling mistakes
* arm64 Documentation update with a minor clarification on TBI
* Miscellaneous:
- Fix missing IPI statistics
- Implement raw_smp_processor_id() using thread_info rather than a
per-CPU variable (better code generation)
- Make MTE checking of in-kernel asynchronous tag faults conditional
on KASAN being enabled
- Minor cleanups, typos

Best regards, Krzysztof Memory controller drivers for v6.11 Make the Freescale IFC driver selectable because it is used now by two drivers: Freescale NAND and generic NOR flash. The patches adjusting defconfig are waiting on the mailing lists to be picked up.
Samsung SoC clock drivers changes for 6.11 1. exynos-clkout: Remove usage of of_device_id table as .of_match_table, because the driver is instantiated as MFD cell, not as standalone platform driver. Populated .of_match_table confused people few times to convert the code to device_get_match_data(), which broke the driver. 2. Mark one of UFS clocks as critical, because having it off stops the system from shutdown. 3. Cleanup: Use kmemdup_array() when applicable.

Hi Mauro, This vimc update for Linux 6.11-rc1 consists of a nine patch series that cleans up and improves the vimc driver, with the end goal of converting it to the V4L2 subdev active state API. The goal of this exercise is to make the API used by a virtual test driver, to increase test coverage. The series starts with 4 random cleanups, to avoid unnecessary iterations (1/9), constify structures (2/9 and 3/9) and rename a weirdly-named enum (4/9). Patch 5/9 then centralizes the subdev internal_ops initialization to prepare for the switch to the active state API. The remaining patches (6/9 to 9/9) convert the vimc entities to the new API one by one. The result has been tested using the libcamera unit tests, which make extensive use of the vimc driver, as well as with v4l2-compliance. The latter reports 4 errors, but they occur already with the latest stage master branch. diff is attached. thanks, -- Shuah linux-vimc-6.11-rc1 This vimc update for Linux 6.11-rc1 consists of a nine patch series that cleans up and improves the vimc driver, with the end goal of converting it to the V4L2 subdev active state API.
