Merge tag 'net-next-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni:
"Core & protocols:
- Improve drop account scalability on NUMA hosts for RAW and UDP
sockets and the backlog, almost doubling the Pps capacity under DoS
- Optimize the UDP RX performance under stress, reducing contention,
revisiting the binary layout of the involved data structs and
implementing NUMA-aware locking. This improves UDP RX performance
by an additional 50%, even more under extreme conditions
- Add support for PSP encryption of TCP connections; this mechanism
has some similarities with IPsec and TLS, but offers superior HW
offloads capabilities
- Ongoing work to support Accurate ECN for TCP. AccECN allows more
than one congestion notification signal per RTT and is a building
block for Low Latency, Low Loss, and Scalable Throughput (L4S)
- Reorganize the TCP socket binary layout for data locality, reducing
the number of touched cachelines in the fastpath
- Refactor skb deferral free to better scale on large multi-NUMA
hosts, this improves TCP and UDP RX performances significantly on
such HW
- Increase the default socket memory buffer limits from 256K to 4M to
better fit modern link speeds
- Improve handling of setups with a large number of nexthop, making
dump operating scaling linearly and avoiding unneeded
synchronize_rcu() on delete
- Improve bridge handling of VLAN FDB, storing a single entry per
bridge instead of one entry per port; this makes the dump order of
magnitude faster on large switches
- Restore IP ID correctly for encapsulated packets at GSO
segmentation time, allowing GRO to merge packets in more scenarios
- Improve netfilter matching performance on large sets
- Improve MPTCP receive path performance by leveraging recently
introduced core infrastructure (skb deferral free) and adopting
recent TCP autotuning changes
- Allow bridges to redirect to a backup port when the bridge port is
administratively down
- Introduce MPTCP 'laminar' endpoint that con be used only once per
connection and simplify common MPTCP setups
- Add RCU safety to dst->dev, closing a lot of possible races
- A significant crypto library API for SCTP, MPTCP and IPv6 SR,
reducing code duplication
- Supports pulling data from an skb frag into the linear area of an
XDP buffer
Things we sprinkled into general kernel code:
- Generate netlink documentation from YAML using an integrated YAML
parser
Driver API:
- Support using IPv6 Flow Label in Rx hash computation and RSS queue
selection
- Introduce API for fetching the DMA device for a given queue,
allowing TCP zerocopy RX on more H/W setups
- Make XDP helpers compatible with unreadable memory, allowing more
easily building DevMem-enabled drivers with a unified XDP/skbs
datapath
- Add a new dedicated ethtool callback enabling drivers to provide
the number of RX rings directly, improving efficiency and clarity
in RX ring queries and RSS configuration
- Introduce a burst period for the health reporter, allowing better
handling of multiple errors due to the same root cause
- Support for DPLL phase offset exponential moving average,
controlling the average smoothing factor
Device drivers:

Merge tag 'for-6.18/block-20250929' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux
Pull block updates from Jens Axboe:
- NVMe pull request via Keith:
- FC target fixes (Daniel)
- Authentication fixes and updates (Martin, Chris)
- Admin controller handling (Kamaljit)
- Target lockdep assertions (Max)
- Keep-alive updates for discovery (Alastair)
- Suspend quirk (Georg)
- MD pull request via Yu:
- Add support for a lockless bitmap.
A key feature for the new bitmap are that the IO fastpath is
lockless. If a user issues lots of write IO to the same bitmap
bit in a short time, only the first write has additional overhead
to update bitmap bit, no additional overhead for the following
writes.
By supporting only resync or recover written data, means in the
case creating new array or replacing with a new disk, there is no
need to do a full disk resync/recovery.
- Switch ->getgeo() and ->bios_param() to using struct gendisk rather
than struct block_device.
- Rust block changes via Andreas. This series adds configuration via
configfs and remote completion to the rnull driver. The series also
includes a set of changes to the rust block device driver API: a few
cleanup patches, and a few features supporting the rnull changes.
The series removes the raw buffer formatting logic from
`kernel::block` and improves the logic available in `kernel::string`
to support the same use as the removed logic.
- floppy arch cleanups
- Reduce the number of dereferencing needed for ublk commands
- Restrict supported sockets for nbd. Mostly done to eliminate a class
of issues perpetually reported by syzbot, by using nonsensical socket
setups.
- A few s390 dasd block fixes
- Fix a few issues around atomic writes
- Improve DMA interation for integrity requests
- Improve how iovecs are treated with regards to O_DIRECT aligment
constraints.
We used to require each segment to adhere to the constraints, now
only the request as a whole needs to.
- Clean up and improve p2p support, enabling use of p2p for metadata
payloads
- Improve locking of request lookup, using SRCU where appropriate
- Use page references properly for brd, avoiding very long RCU sections
- Fix ordering of recursively submitted IOs
- Clean up and improve updating nr_requests for a live device
- Various fixes and cleanups

Pull SoC dt updates from Arnd Bergmann:
"There are five sets of new SoCs that get added in existing families,
all of them being either upgrades or cut-down versions of the older
chips:
- Apple M2 Pro, M2 Max and M2 Ultra, used in the 2022/2023 generation
of high-end workstations and laptops from Apple. Linux has been
working on these for a while but stil requires patches.
- Axis Artpec8 is an Armv8 chip based on Samsung Exynos design,
unlike the earlier Armv7 Artpec6 from the same company that was
part of a separate family of chips.
- NXP i.MX91 is a cut-down version of i.MX93, using only a single
Cortex-A55 core.
- Qualcomm Lemans Auto is a variant of the Lemans SoC that was
originally merged under the sa8775p name, the differences being
mostly the firmware configuration of the platform.
- Four new Renesas SoCs RZ/T2H (r9a09g077m44), RZ/N2H (r9a09g087m44),
RZ/T2H (r9a09g077), and RZ/N2H (r9a09g087) are all industrial
bedded SoCs based on Cortex-A55 cores
In total, there are 65 new machines, including:
- Industrial embedded system and single-board computers based on NXP,
Allwinner, TI, Rockchips, Marvell, Xilinx Spacemit, Starfive chips.
- Reference boards for the newly added Renesas, Qualcomm, NXP and
Axis ARMv8 chips as well as Microchip's MPFS RISC-V SoC
- Laptops and Workstations using Apple M2 and Qualcomm Snapdragon X1
chips.
- Several Samsung phones using Qualcomm Snapdragon chips
- Set-top boxes based on Allwinner H313
- Five BMC boards using 32-bit ASpeed SoCs
- Three network routers using IXP4xx (ARMv5!) and Broadcom bcm4708
(ARMv7) SoCs
Two machines get phased out because they were available only in small
quantities but never made it into products: one STi407 based reference
board, and a Snapdragon 845 based Chromebook.
Aside from the newly added machines, a lot of work went into improving
hardware support on the existing machines and cleaning up contents for
validation"

Pull irq chip driver updates from Thomas Gleixner: - Use the startup/shutdown callbacks for the PCI/MSI per device interrupt domains. This allows us to initialize the RISCV PLIC interrupt hierarchy correctly and provides a mechanism to decouple the masking and unmasking during run-time from the expensive PCI mask and unmask when the underlying MSI provider implementation allows the interrupt to be masked. - Initialize the RISCV PLIC MSI interrupt hierarchy correctly so that the affinity assignment works correctly by switching it over to the startup/shutdown scheme - Allow MSI providers to opt out from masking a PCI/MSI interrupt at the PCI device during operation when the provider can mask the interrupt at the underlying interrupt chip. This reduces the overhead in scenarios where disable_irq()/enable_irq() is utilized frequently by a driver. The PCI/MSI device level [un]masking is only required on startup and shutdown in this case. - Remove the conditional mask/unmask logic in the PCI/MSI layer as this is now handled unconditionally. - Replace the hardcoded interrupt routing in the Loongson EIOINTC interrupt driver to respect the firmware settings and spread them out to different CPU interrupt inputs so that the demultiplexing handler only needs to read only a single 64-bit status register instead of four, which significantly reduces the overhead in VMs as the status register access causes a VM exit. - Add support for the new AST2700 SCU interrupt controllers - Use the legacy interrupt domain setup for the Loongson PCH-LPC interrupt controller, which resembles the x86 legacy PIC setup and has the same hardcoded legacy requirements. - The usual set of cleanups, fixes and improvements all over the place * tag 'irq-drivers-2025-09-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (25 commits) irqchip/loongson-pch-lpc: Use legacy domain for PCH-LPC IRQ controller PCI/MSI: Remove the conditional parent [un]mask logic irqchip/msi-lib: Honor the MSI_FLAG_PCI_MSI_MASK_PARENT flag irqchip/aspeed-scu-ic: Add support for AST2700 SCU interrupt controllers dt-bindings: interrupt-controller: aspeed: Add AST2700 SCU IC compatibles dt-bindings: mfd: aspeed: Add AST2700 SCU compatibles irqchip/aspeed-scu-ic: Refactor driver to support variant-based initialization irqchip/gic-v5: Fix error handling in gicv5_its_irq_domain_alloc() irqchip/gic-v5: Fix loop in gicv5_its_create_itt_two_level() cleanup path irqchip/gic-v5: Delete a stray tab irqchip/sg2042-msi: Set irq type according to DT configuration riscv: sophgo: dts: sg2044: Change msi irq type to IRQ_TYPE_EDGE_RISING riscv: sophgo: dts: sg2042: Change msi irq type to IRQ_TYPE_EDGE_RISING irqchip/gic-v2m: Handle Multiple MSI base IRQ Alignment irqchip/renesas-rzg2l: Remove dev_err_probe() if error is -ENOMEM irqchip: Use int type to store negative error codes irqchip/gic-v5: Remove the redundant ITS cache invalidation PCI/MSI: Check MSI_FLAG_PCI_MSI_MASK_PARENT in cond_[startup|shutdown]_parent() irqchip/loongson-eiointc: Add multiple interrupt pin routing support irqchip/loongson-eiointc: Route interrupt parsed from bios table ... |

Merge tag 'x86_apic_for_v6.18_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 SEV and apic updates from Borislav Petkov: - Add functionality to provide runtime firmware updates for the non-x86 parts of an AMD platform like the security processor (ASP) firmware, modules etc, for example. The intent being that these updates are interim, live fixups before a proper BIOS update can be attempted - Add guest support for AMD's Secure AVIC feature which gives encrypted guests the needed protection against a malicious hypervisor generating unexpected interrupts and injecting them into such guest, thus interfering with its operation in an unexpected and negative manner. The advantage of this scheme is that the guest determines which interrupts and when to accept them vs leaving that to the benevolence (or not) of the hypervisor - Strictly separate the startup code from the rest of the kernel where former is executed from the initial 1:1 mapping of memory. The problem was that the toolchain-generated version of the code was being executed from a different mapping of memory than what was "assumed" during code generation, needing an ever-growing pile of fixups for absolute memory references which are invalid in the early, 1:1 memory mapping during boot. The major advantage of this is that there's no need to check the 1:1 mapping portion of the code for absolute relocations anymore and get rid of the RIP_REL_REF() macro sprinkling all over the place.

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon:
"There's good stuff across the board, including some nice mm
improvements for CPUs with the 'noabort' BBML2 feature and a clever
patch to allow ptdump to play nicely with block mappings in the
vmalloc area.
Confidential computing:
- Add support for accepting secrets from firmware (e.g. ACPI CCEL)
and mapping them with appropriate attributes.
CPU features:
- Advertise atomic floating-point instructions to userspace
- Extend Spectre workarounds to cover additional Arm CPU variants
- Extend list of CPUs that support break-before-make level 2 and
guarantee not to generate TLB conflict aborts for changes of
mapping granularity (BBML2_NOABORT)
- Add GCS support to our uprobes implementation.
Documentation:
- Remove bogus SME documentation concerning register state when
entering/exiting streaming mode.
Entry code:
- Switch over to the generic IRQ entry code (GENERIC_IRQ_ENTRY)
- Micro-optimise syscall entry path with a compiler branch hint.
Memory management:
- Enable huge mappings in vmalloc space even when kernel page-table
dumping is enabled
- Tidy up the types used in our early MMU setup code
- Rework rodata= for closer parity with the behaviour on x86
- For CPUs implementing BBML2_NOABORT, utilise block mappings in the
linear map even when rodata= applies to virtual aliases
- Don't re-allocate the virtual region between '_text' and '_stext',
as doing so confused tools parsing /proc/vmcore.
Miscellaneous:
- Clean-up Kconfig menuconfig text for architecture features
- Avoid redundant bitmap_empty() during determination of supported
SME vector lengths
- Re-enable warnings when building the 32-bit vDSO object
- Avoid breaking our eggs at the wrong end.
Perf and PMUs:
- Support for v3 of the Hisilicon L3C PMU
- Support for Hisilicon's MN and NoC PMUs
- Support for Fujitsu's Uncore PMU
- Support for SPE's extended event filtering feature
- Preparatory work to enable data source filtering in SPE
- Support for multiple lanes in the DWC PCIe PMU
- Support for i.MX94 in the IMX DDR PMU driver
- MAINTAINERS update (Thank you, Yicong)
- Minor driver fixes (PERF_IDX2OFF() overflow, CMN register offsets).
Selftests:
- Add basic LSFE check to the existing hwcaps test
- Support nolibc in GCS tests
- Extend SVE ptrace test to pass unsupported regsets and invalid
vector lengths
- Minor cleanups (typos, cosmetic changes).
System registers:

Merge tag 'vfs-6.18-rc1.inode' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs inode updates from Christian Brauner:
"This contains a series I originally wrote and that Eric brought over
the finish line. It moves out the i_crypt_info and i_verity_info
pointers out of 'struct inode' and into the fs-specific part of the
inode.
So now the few filesytems that actually make use of this pay the price
in their own private inode storage instead of forcing it upon every
user of struct inode.
The pointer for the crypt and verity info is simply found by storing
an offset to its address in struct fsverity_operations and struct
fscrypt_operations. This shrinks struct inode by 16 bytes.
I hope to move a lot more out of it in the future so that struct inode
becomes really just about very core stuff that we need, much like
struct dentry and struct file, instead of the dumping ground it has
become over the years.
On top of this are a various changes associated with the ongoing inode
lifetime handling rework that multiple people are pushing forward:
- Stop accessing inode->i_count directly in f2fs and gfs2. They
simply should use the __iget() and iput() helpers
- Make the i_state flags an enum
- Rework the iput() logic
Currently, if we are the last iput, and we have the I_DIRTY_TIME
bit set, we will grab a reference on the inode again and then mark
it dirty and then redo the put. This is to make sure we delay the
time update for as long as possible
We can rework this logic to simply dec i_count if it is not 1, and
if it is do the time update while still holding the i_count
reference
Then we can replace the atomic_dec_and_lock with locking the
->i_lock and doing atomic_dec_and_test, since we did the
atomic_add_unless above
- Add an icount_read() helper and convert everyone that accesses
inode->i_count directly for this purpose to use the helper
- Expand dump_inode() to dump more information about an inode helping
in debugging
- Add some might_sleep() annotations to iput() and associated
helpers"

s390/mm: Add memory allocation profiling hooks
Similar to common code changes [1] add alloc_hook() wrappers to page table
allocation functions to allow for memory allocation profiling.
If CONFIG_MEM_ALLOC_PROFILING is enabled call sites of page table
allocations are accounted, instead of e.g. only crst_table_alloc() and
page_table_alloc(). This allows for slightly better profiling data, and the
output of /proc/allocinfo is similar to other architectures.
Without alloc_hook() wrappers the output of /proc/allocinfo looks like
this:
17096704 4174 mm/memory.c:1061 func:folio_prealloc
