Pull RTLA updates from Steven Rostedt:
- Remove unused function declarations
Some functions were removed in recent code consolidation 6.18, but
their prototypes were not removed from headers. Remove them.
- Set stop threshold after enabling instances
Prefer recording samples without stopping on them on the start of
tracing to stopping on samples that are never recorded. This fixes
flakiness of some RTLA tests and unifies behavior of sample
collection between tracefs mode and BPF mode.
- Consolidate usage help message implementation
RTLA tools (osnoise-top, osnoise-hist, timerlat-top, timerlat-hist)
each implement usage help individually. Move common logic between
them into a new function to reduce code duplication.
- Add BPF actions feature
Add option --bpf-action to attach a BPF program (passed as filename
of its ELF representation) to be executed via BPF tail call at
latency threshold.
- Consolidate command line option parsing
Each RTLA tool implements the parsing of command line options
individually. Now that we have a common structure for parameters,
unify the parsing of those options common among all four tools into
one function.
- De-duplicate cgroup common code
Two functions in utils.c, setting cgroup for comm and setting cgroup
for pid, duplicate code for constructing the cgroup path. Extract it
to a new helper function.
- String and error handling fixes and cleanups
There were several instances of unsafe string and error handling that
could cause invalid memory access; fix them. Also, remove a few
unused headers, update .gitignore, and deduplicate code.

Pull runtime verifier updates from Steven Rostedt:
- Refactor da_monitor to minimize macros
Complete refactor of da_monitor.h to reduce reliance on macros
generating functions. Use generic static functions and uses the
preprocessor only when strictly necessary (e.g. for tracepoint
handlers).
The change essentially relies on functions with generic names (e.g.
da_handle) instead of monitor-specific as well adding the need to
define constant (e.g. MONITOR_NAME, MONITOR_TYPE) before including
the header rather than calling macros that would define functions.
Also adapt monitors and documentation accordingly.
- Cleanup DA code generation scripts
Clean up functions in dot2c removing reimplementations of trivial
library functions (__buff_to_string) and removing some other unused
intermediate steps.
- Annotate functions with types in the rvgen python scripts
- Remove superfluous assignments and cleanup generated code
The rvgen scripts generate a superfluous assignment to 0 for enum
variables and don't add commas to the last elements, which is against
the kernel coding standards. Change the generation process for a
better compliance and slightly simpler logic.
- Remove superfluous declarations from generated code
The monitor container source files contained a declaration and a
definition for the rv_monitor variable. The former is superfluous and
was removed.
- Fix reference to outdated documentation

Pull nfsd updates from Chuck Lever:
"Neil Brown and Jeff Layton contributed a dynamic thread pool sizing
mechanism for NFSD. The sunrpc layer now tracks minimum and maximum
thread counts per pool, and NFSD adjusts running thread counts based
on workload: idle threads exit after a timeout when the pool exceeds
its minimum, and new threads spawn automatically when all threads are
busy. Administrators control this behavior via the nfsdctl netlink
interface.
Rick Macklem, FreeBSD NFS maintainer, generously contributed server-
side support for the POSIX ACL extension to NFSv4, as specified in
draft-ietf-nfsv4-posix-acls. This extension allows NFSv4 clients to
get and set POSIX access and default ACLs using native NFSv4
operations, eliminating the need for sideband protocols. The feature
is gated by a Kconfig option since the IETF draft has not yet been
ratified.
Chuck Lever delivered numerous improvements to the xdrgen tool. Error
reporting now covers parsing, AST transformation, and invalid
declarations. Generated enum decoders validate incoming values against
valid enumerator lists. New features include pass-through line support
for embedding C directives in XDR specifications, 16-bit integer
types, and program number definitions. Several code generation issues
were also addressed.
When an administrator revokes NFSv4 state for a filesystem via the
unlock_fs interface, ongoing async COPY operations referencing that
filesystem are now cancelled, with CB_OFFLOAD callbacks notifying
affected clients.
The remaining patches in this pull request are clean-ups and minor
optimizations. Sincere thanks to all contributors, reviewers, testers,
and bug reporters who participated in the v7.0 NFSD development cycle"

Pull networking updates from Paolo Abeni:
"Core & protocols:
- A significant effort all around the stack to guide the compiler to
make the right choice when inlining code, to avoid unneeded calls
for small helper and stack canary overhead in the fast-path.
This generates better and faster code with very small or no text
size increases, as in many cases the call generated more code than
the actual inlined helper.
- Extend AccECN implementation so that is now functionally complete,
also allow the user-space enabling it on a per network namespace
basis.
- Add support for memory providers with large (above 4K) rx buffer.
Paired with hw-gro, larger rx buffer sizes reduce the number of
buffers traversing the stack, dincreasing single stream CPU usage
by up to ~30%.
- Do not add HBH header to Big TCP GSO packets. This simplifies the
RX path, the TX path and the NIC drivers, and is possible because
user-space taps can now interpret correctly such packets without
the HBH hint.
- Allow IPv6 routes to be configured with a gateway address that is
resolved out of a different interface than the one specified,
aligning IPv6 to IPv4 behavior.
- Multi-queue aware sch_cake. This makes it possible to scale the
rate shaper of sch_cake across multiple CPUs, while still enforcing
a single global rate on the interface.
- Add support for the nbcon (new buffer console) infrastructure to
netconsole, enabling lock-free, priority-based console operations
that are safer in crash scenarios.
- Improve the TCP ipv6 output path to cache the flow information,
saving cpu cycles, reducing cache line misses and stack use.
- Improve netfilter packet tracker to resolve clashes for most
protocols, avoiding unneeded drops on rare occasions.
- Add IP6IP6 tunneling acceleration to the flowtable infrastructure.
- Reduce tcp socket size by one cache line.
- Notify neighbour changes atomically, avoiding inconsistencies
between the notification sequence and the actual states sequence.
- Add vsock namespace support, allowing complete isolation of vsocks
across different network namespaces.
- Improve xsk generic performances with cache-alignment-oriented
optimizations.
- Support netconsole automatic target recovery, allowing netconsole
to reestablish targets when underlying low-level interface comes
back online.
Driver API:
- Support for switching the working mode (automatic vs manual) of a
DPLL device via netlink.
- Introduce PHY ports representation to expose multiple front-facing
media ports over a single MAC.
- Introduce "rx-polarity" and "tx-polarity" device tree properties,
to generalize polarity inversion requirements for differential
signaling.
- Add helper to create, prepare and enable managed clocks.
- Add ethernet driver for MaxLinear MxL862xx switches
- Remove parallel-port Ethernet driver.
- Convert existing driver timestamp configuration reporting to
hwtstamp_get and remove legacy ioctl().
- Convert existing drivers to .get_rx_ring_count(), simplifing the RX
ring count retrieval. Also remove the legacy fallback path.

- Convert portdrv to use pcie_port_bus_type.probe() and .remove()
callbacks so .probe() and .remove() can eventually be removed from
struct device_driver (Uwe Kleine-König)
Error handling:
- Clear stale errors on reporting agents upon probe so they don't
look like recent errors (Lukas Wunner)
- Add generic RAS tracepoint for hotplug events (Shuai Xue)

- Skip PME_Turn_Off broadcast and L2/L3 transition during suspend if
link is not up to avoid an unnecessary timeout (Manivannan
Sadhasivam)
- Revert dw-rockchip, qcom, and DWC core changes that used link-up
IRQs to trigger enumeration instead of waiting for link to be up
because the PCI core doesn't allocate bus number space for
hierarchies that might be attached (Niklas Cassel)
- Make endpoint iATU entry for MSI permanent instead of programming
it dynamically, which is slow and racy with respect to other
concurrent traffic, e.g., eDMA (Koichiro Den)
- Use iMSI-RX MSI target address when possible to fix endpoints using
32-bit MSI (Shawn Lin)
- Allow DWC host controller driver probe to continue if device is not

Pull slab updates from Vlastimil Babka:
- The percpu sheaves caching layer was introduced as opt-in in 6.18 and
now we enable it for all caches and remove the previous cpu (partial)
slab caching mechanism.
Besides the lower locking overhead and much more likely fastpath when
freeing, this removes the rather complicated code related to the cpu
slab lockless fastpaths (using this_cpu_try_cmpxchg128/64) and all
its complications for PREEMPT_RT or kmalloc_nolock().
The lockless slab freelist+counters update operation using
try_cmpxchg128/64 remains and is crucial for freeing remote NUMA
objects, and to allow flushing objects from sheaves to slabs mostly
without the node list_lock (Vlastimil Babka)
- Eliminate slabobj_ext metadata overhead when possible. Instead of
using kmalloc() to allocate the array for memcg and/or allocation
profiling tag pointers, use leftover space in a slab or per-object
padding due to alignment (Harry Yoo)

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

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

This is very similar to the case where multiple devices are grouped

to software.
Otherwise there's been quite a bit of work on existing drivers, both

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

net: macb: Fix tx/rx malfunction after phy link down and up
In commit 99537d5c476c ("net: macb: Relocate mog_init_rings() callback
from macb_mac_link_up() to macb_open()"), the mog_init_rings() callback
was moved from macb_mac_link_up() to macb_open() to resolve a deadlock
issue. However, this change introduced a tx/rx malfunction following
phy link down and up events. The issue arises from a mismatch between
the software queue->tx_head, queue->tx_tail, queue->rx_prepared_head,
and queue->rx_tail values and the hardware's internal tx/rx queue
pointers.
According to the Zynq UltraScale TRM [1], when tx/rx is disabled, the
internal tx queue pointer resets to the value in the tx queue base
address register, while the internal rx queue pointer remains unchanged.
The following is quoted from the Zynq UltraScale TRM:
When transmit is disabled, with bit [3] of the network control register
set low, the transmit-buffer queue pointer resets to point to the address
indicated by the transmit-buffer queue base address register. Disabling
receive does not have the same effect on the receive-buffer queue
pointer.
Additionally, there is no need to reset the RBQP and TBQP registers in a
phy event callback. Therefore, move macb_init_buffers() to macb_open().
In a phy link up event, the only required action is to reset the tx
software head and tail pointers to align with the hardware's behavior.

Commit 95540ad6747c ("net: ti: icssg-prueth: Add support for HSR frame

which relies on functions such as is_hsr_master() provided by the HSR

disabled, this driver still requires an optional dependency on HSR.
Otherwise, build failures will occur when icssg-prueth is built-in

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

net: dsa: add basic initial driver for MxL862xx switches
Add very basic DSA driver for MaxLinear's MxL862xx switches.
In contrast to previous MaxLinear switches the MxL862xx has a built-in
processor that runs a sophisticated firmware based on Zephyr RTOS.
Interaction between the host and the switch hence is organized using a
software API of that firmware rather than accessing hardware registers
directly.
Add descriptions of the most basic firmware API calls to access the
built-in MDIO bus hosting the 2.5GE PHYs, basic port control as well as
setting up the CPU port.
Implement a very basic DSA driver using that API which is sufficient to
get packets flowing between the user ports and the CPU port.
The firmware offers all features one would expect from a modern switch
hardware, they are going to be added one by one in follow-up patch
series.

1) Fix net-next-only use-after-free bug in nf_tables rbtree set:
Expired elements cannot be released right away after unlink anymore
because there is no guarantee that the binary-search blob is going to

2) Fix esoteric bug in nf_queue with udp fraglist gro, broken since

4) Use dedicated slab for flowtable entries, currently the -512 cache
is used, which is wasteful. From Qingfang Deng.
5) Recent net-next update extended existing test for ip6ip6 tunnels, add
the required /config entry. Test still passed by accident because the
previous tests network setup gets re-used, so also update the test so
it will fail in case the ip6ip6 tunnel interface cannot be added.
6) Fix 'nft get element mytable myset { 1.2.3.4 }' on big endian
platforms, this was broken since code was added in v5.1.
7) Fix nf_tables counter reset support on 32bit platforms, where counter
reset may cause huge values to appear due to wraparound.
Broken since reset feature was added in v6.11. From Anders Grahn.
8-11) update nf_tables rbtree set type to detect partial

xfrm: reduce struct sec_path size
The mentioned struct has an hole and uses unnecessary wide type to
store MAC length and indexes of very small arrays.
It's also embedded into the skb_extensions, and the latter, due

Reordering and the sec_path fields, shrinking xfrm_offload.orig_mac_len

x86: keep legacy generated vdso files around in .gitignore file
Commit 93d73005bff4 ("x86/entry/vdso: Rename vdso_image_* to
vdso*_image") updated the vdso .gitignore file with the new filenames,
which is certainly not incorrect.
However, while adding new generated names is obviously the right thing
to do, you should *not* immediately remove the old filenames from the
.gitignore file when things move around or get renamed, because people
still have those old generated files in their build trees - and they
haven't suddenly become valid files to commit to the repository just
because they were moved or renamed.
While it's mostly just a slight visual nuisance for 'git status' that
can be fixed up with a clean build tree, it can become more serious than
that: see for example commit 04a3389b3535 ("Remove stale generated
'genheaders' file").
That commit removed up a stale generated file that had been carelessly
committed by a kernel developer because it wasn't properly ignored any
more and thus showed up as a new file in their tree.

Note that sk->sk_write_space was never called directly with MPTCP

it from mptcp_write_space() is not supposed to change the current

This patch is shared early to ease discussions around future RFC and

net: netconsole: convert to NBCON console infrastructure
This series adds support for the nbcon (new buffer console) infrastructure
to netconsole, enabling lock-free, priority-based console operations that
are safer in crash scenarios.
The implementation is introduced in three steps:
0) Extend printk to expose CPU and taskname (task->comm) where the
printk originated from. (Thanks John and Petr for the support in
getting this done)
1) Refactor the message fragmentation logic into a reusable helper function
2) Extend nbcon support to non-extended (basic) consoles using the same
infrastructure.
The initial discussion about it appeared a while ago in [1], in order to
solve Mike's HARDIRQ-safe -> HARDIRQ-unsafe lock order warning, and the root
cause is that some hosts were calling IRQ unsafe locks from inside console
lock.
At that time, we didn't have the CON_NBCON_ATOMIC_UNSAFE yet. John
kindly implemented CON_NBCON_ATOMIC_UNSAFE in 187de7c212e5 ("printk:
nbcon: Allow unsafe write_atomic() for panic"), and now we can
implement netconsole on top of nbcon.
Important to note that netconsole continues to call netpoll and the
network TX helpers with interrupt disable, given the TX are called with
target_list_lock.
====================

netconsole: Use printk context for CPU and task information
Use the CPU and task name captured at printk() time from
nbcon_write_context instead of querying the current execution context.
This provides accurate information about where the message originated,
rather than where netconsole happens to be running.
For CPU, use wctxt->cpu instead of raw_smp_processor_id().
For taskname, use wctxt->comm directly which contains the task
name captured at printk time.
This change ensures netconsole outputs reflect the actual context that
generated the log message, which is especially important when the
console driver runs asynchronously in a dedicated thread.

netconsole: convert to NBCON console infrastructure
Convert netconsole from the legacy console API to the NBCON framework.
NBCON provides threaded printing which unblocks printk()s and flushes in
a thread, decoupling network TX from printk() when netconsole is
in use.
Since netconsole relies on the network stack which cannot safely operate
from all atomic contexts, mark both consoles with
CON_NBCON_ATOMIC_UNSAFE. (See discussion in [1])
CON_NBCON_ATOMIC_UNSAFE restricts write_atomic() usage to emergency
scenarios (panic) where regular messages are sent in threaded mode.
Implementation changes:
- Unify write_ext_msg() and write_msg() into netconsole_write()
- Add device_lock/device_unlock callbacks to manage target_list_lock
- Use nbcon_enter_unsafe()/nbcon_exit_unsafe() around network
operations.
- If nbcon_enter_unsafe() fails, just return given netconsole lost
the ownership of the console.
- Set write_thread and write_atomic callbacks (both use same function)

netconsole: extract message fragmentation into send_msg_udp()
Extract the message fragmentation logic from write_msg() into a
dedicated send_msg_udp() function. This improves code readability
and prepares for future enhancements.
The new send_msg_udp() function handles splitting messages that
exceed MAX_PRINT_CHUNK into smaller fragments and sending them
sequentially. This function is placed before send_ext_msg_udp()
to maintain a logical ordering of related functions.
No functional changes - this is purely a refactoring commit.

printk: Add execution context (task name/CPU) to printk_info
Extend struct printk_info to include the task name, pid, and CPU
number where printk messages originate. This information is captured
at vprintk_store() time and propagated through printk_message to
nbcon_write_context, making it available to nbcon console drivers.
This is useful for consoles like netconsole that want to include
execution context in their output, allowing correlation of messages
with specific tasks and CPUs regardless of where the console driver
actually runs.
The feature is controlled by CONFIG_PRINTK_EXECUTION_CTX, which is
automatically selected by CONFIG_NETCONSOLE_DYNAMIC. When disabled,
the helper functions compile to no-ops with no overhead.
