Pull netfs updates from Christian Brauner:
"This contains the work to improve read/write performance for the new
netfs library.
The main performance enhancing changes are:
- Define a structure, struct folio_queue, and a new iterator type,
ITER_FOLIOQ, to hold a buffer as a replacement for ITER_XARRAY. See
that patch for questions about naming and form.
ITER_FOLIOQ is provided as a replacement for ITER_XARRAY. The
problem with an xarray is that accessing it requires the use of a
lock (typically the RCU read lock) - and this means that we can't
supply iterate_and_advance() with a step function that might sleep
(crypto for example) without having to drop the lock between pages.
ITER_FOLIOQ is the iterator for a chain of folio_queue structs,
where each folio_queue holds a small list of folios. A folio_queue
struct is a simpler structure than xarray and is not subject to
concurrent manipulation by the VM. folio_queue is used rather than
a bvec[] as it can form lists of indefinite size, adding to one end
and removing from the other on the fly.
- Provide a copy_folio_from_iter() wrapper.
- Make cifs RDMA support ITER_FOLIOQ.
- Use folio queues in the write-side helpers instead of xarrays.
- Add a function to reset the iterator in a subrequest.
- Simplify the write-side helpers to use sheaves to skip gaps rather
than trying to work out where gaps are.
- In afs, make the read subrequests asynchronous, putting them into
work items to allow the next patch to do progressive
unlocking/reading.
- Overhaul the read-side helpers to improve performance.
- Fix the caching of a partial block at the end of a file.
- Allow a store to be cancelled.
Then some changes for cifs to make it use folio queues instead of
xarrays for crypto bufferage:
- Use raw iteration functions rather than manually coding iteration
when hashing data.
- Switch to using folio_queue for crypto buffers.
- Remove the xarray bits.
Make some adjustments to the /proc/fs/netfs/stats file such that:
- All the netfs stats lines begin 'Netfs:' but change this to
something a bit more useful.
- Add a couple of stats counters to track the numbers of skips and
waits on the per-inode writeback serialisation lock to make it
easier to check for this as a source of performance loss.
Miscellaneous work:
- Ensure that the sb_writers lock is taken around
vfs_{set,remove}xattr() in the cachefiles code.
- Reduce the number of conditional branches in netfs_perform_write().
- Move the CIFS_INO_MODIFIED_ATTR flag to the netfs_inode struct and
remove cifs_post_modify().
- Move the max_len/max_nr_segs members from netfs_io_subrequest to
netfs_io_request as they're only needed for one subreq at a time.
- Add an 'unknown' source value for tracing purposes.
- Remove NETFS_COPY_TO_CACHE as it's no longer used.
- Set the request work function up front at allocation time.
- Use bh-disabling spinlocks for rreq->lock as cachefiles completion
may be run from block-filesystem DIO completion in softirq context.
- Remove fs/netfs/io.c"

Pull procfs updates from Christian Brauner:
"This contains the following changes for procfs:
- Add config options and parameters to block forcing memory writes.
This adds a Kconfig option and boot param to allow removing the
FOLL_FORCE flag from /proc/<pid>/mem write calls as this can be
used in various attacks.
The traditional forcing behavior is kept as default because it can
break GDB and some other use cases.
This is the simpler version that you had requested.
- Restrict overmounting of ephemeral entities.
It is currently possible to mount on top of various ephemeral
entities in procfs. This specifically includes magic links. To
recap, magic links are links of the form /proc/<pid>/fd/<nr>. They
serve as references to a target file and during path lookup they
cause a jump to the target path. Such magic links disappear if the
corresponding file descriptor is closed.
Currently it is possible to overmount such magic links. This is
mostly interesting for an attacker that wants to somehow trick a
process into e.g., reopening something that it didn't intend to
reopen or to hide a malicious file descriptor.
But also it risks leaking mounts for long-running processes. When
overmounting a magic link like above, the mount will not be
detached when the file descriptor is closed. Only the target
mountpoint will disappear. Which has the consequence of making it
impossible to unmount that mount afterwards. So the mount will
stick around until the process exits and the /proc/<pid>/ directory
is cleaned up during proc_flush_pid() when the dentries are pruned
and invalidated.
That in turn means it's possible for a program to accidentally leak
mounts and it's also possible to make a task leak mounts without
it's knowledge if the attacker just keeps overmounting things under
/proc/<pid>/fd/<nr>.
Disallow overmounting of such ephemeral entities.
- Cleanup the readdir method naming in some procfs file operations.
- Replace kmalloc() and strcpy() with a simple kmemdup() call"

Pull misc vfs updates from Christian Brauner:
"This contains the usual pile of misc updates:
Features:
- Add F_CREATED_QUERY fcntl() that allows userspace to query whether
a file was actually created. Often userspace wants to know whether
an O_CREATE request did actually create a file without using
O_EXCL. The current logic is that to first attempts to open the
file without O_CREAT | O_EXCL and if ENOENT is returned userspace
tries again with both flags. If that succeeds all is well. If it
now reports EEXIST it retries.
That works fairly well but some corner cases make this more
involved. If this operates on a dangling symlink the first openat()
without O_CREAT | O_EXCL will return ENOENT but the second openat()
with O_CREAT | O_EXCL will fail with EEXIST.
The reason is that openat() without O_CREAT | O_EXCL follows the
symlink while O_CREAT | O_EXCL doesn't for security reasons. So
it's not something we can really change unless we add an explicit
opt-in via O_FOLLOW which seems really ugly.
All available workarounds are really nasty (fanotify, bpf lsm etc)
so add a simple fcntl().
- Try an opportunistic lookup for O_CREAT. Today, when opening a file
we'll typically do a fast lookup, but if O_CREAT is set, the kernel
always takes the exclusive inode lock. This was likely done with
the expectation that O_CREAT means that we always expect to do the
create, but that's often not the case. Many programs set O_CREAT
even in scenarios where the file already exists (see related
F_CREATED_QUERY patch motivation above).
The series contained in the pr rearranges the pathwalk-for-open
code to also attempt a fast_lookup in certain O_CREAT cases. If a
positive dentry is found, the inode_lock can be avoided altogether
and it can stay in rcuwalk mode for the last step_into.
- Expose the 64 bit mount id via name_to_handle_at()
Now that we provide a unique 64-bit mount ID interface in statx(2),
we can now provide a race-free way for name_to_handle_at(2) to
provide a file handle and corresponding mount without needing to
worry about racing with /proc/mountinfo parsing or having to open a
file just to do statx(2).
While this is not necessary if you are using AT_EMPTY_PATH and
don't care about an extra statx(2) call, users that pass full paths
into name_to_handle_at(2) need to know which mount the file handle
comes from (to make sure they don't try to open_by_handle_at a file
handle from a different filesystem) and switching to AT_EMPTY_PATH
would require allocating a file for every name_to_handle_at(2) call
- Add a per dentry expire timeout to autofs
There are two fairly well known automounter map formats, the autofs
format and the amd format (more or less System V and Berkley).
Some time ago Linux autofs added an amd map format parser that
implemented a fair amount of the amd functionality. This was done
within the autofs infrastructure and some functionality wasn't
implemented because it either didn't make sense or required extra
kernel changes. The idea was to restrict changes to be within the
existing autofs functionality as much as possible and leave changes
with a wider scope to be considered later.
One of these changes is implementing the amd options:
1) "unmount", expire this mount according to a timeout (same as
the current autofs default).
2) "nounmount", don't expire this mount (same as setting the
autofs timeout to 0 except only for this specific mount) .
3) "utimeout=<seconds>", expire this mount using the specified
timeout (again same as setting the autofs timeout but only for
this mount)
To implement these options per-dentry expire timeouts need to be
implemented for autofs indirect mounts. This is because all map
keys (mounts) for autofs indirect mounts use an expire timeout
stored in the autofs mount super block info. structure and all
indirect mounts use the same expire timeout.
Fixes:
- Fix missing fput for FSCONFIG_SET_FD in autofs
- Use param->file for FSCONFIG_SET_FD in coda
- Delete the 'fs/netfs' proc subtreee when netfs module exits
- Make sure that struct uid_gid_map fits into a single cacheline
- Don't flush in-flight wb switches for superblocks without cgroup
writeback
- Correcting the idmapping mount example in the idmapping
documentation
- Fix a race between evice_inodes() and find_inode() and iput()
- Refine the show_inode_state() macro definition in writeback code
- Prevent dump_mapping() from accessing invalid dentry.d_name.name
- Show actual source for debugfs in /proc/mounts
- Annotate data-race of busy_poll_usecs in eventpoll
- Don't WARN for racy path_noexec check in exec code
- Handle OOM on mnt_warn_timestamp_expiry()
- Fix some spelling in the iomap design documentation
- Fix typo in procfs comment
- Fix typo in fs/namespace.c comment
Cleanups:
- Add the VFS git tree to the MAINTAINERS file
- Move FMODE_UNSIGNED_OFFSET to fop_flags freeing up another f_mode
bit in struct file bringing us to 5 free f_mode bits
- Remove the __I_DIO_WAKEUP bit from i_state flags as we can simplify

- Remove the unused path_put_init() helper
- Replace a __u32 with u32 for s_fsnotify_mask as __u32 is uapi

using the bit based wait apis we're now using the var event apis
and using the individual bytes of the i_state member to wait on
state changes

things, replaces two previously existing thermal zone operations with
one allowing driver implementations to be much simpler
There is also a new thermal core testing module allowing mock thermal

Pull power management updates from Rafael Wysocki:
"By the number of new lines of code, the most visible change here is
the addition of hybrid CPU capacity scaling support to the
intel_pstate driver. Next are the amd-pstate driver changes related to
the calculation of the AMD boost numerator and preferred core
detection.
As far as new hardware support is concerned, the intel_idle driver
will now handle Granite Rapids Xeon processors natively, the
intel_rapl power capping driver will recognize family 1Ah of AMD
processors and Intel ArrowLake-U chipos, and intel_pstate will handle
Granite Rapids and Sierra Forest chips in the out-of-band (OOB) mode.
Apart from the above, there is a usual collection of assorted fixes
and code cleanups in many places and there are tooling updates.
Specifics:
- Remove LATENCY_MULTIPLIER from cpufreq (Qais Yousef)
- Add support for Granite Rapids and Sierra Forest in OOB mode to the
intel_pstate cpufreq driver (Srinivas Pandruvada)
- Add basic support for CPU capacity scaling on x86 and make the
intel_pstate driver set asymmetric CPU capacity on hybrid systems
without SMT (Rafael Wysocki)
- Add missing MODULE_DESCRIPTION() macros to the powerpc cpufreq
driver (Jeff Johnson)
- Several OF related cleanups in cpufreq drivers (Rob Herring)

The LAN8650/1 combines a Media Access Controller (MAC) and an Ethernet PHY to enable 10BASE-T1S networks. The Ethernet Media Access Controller (MAC) module implements a 10 Mbps half duplex Ethernet MAC, compatible with the IEEE 802.3 standard and a 10BASE-T1S physical layer transceiver integrated into the LAN8650/1. The communication between the Host and the MAC-PHY is specified in the OPEN Alliance 10BASE-T1x MACPHY Serial Interface (TC6).

Documentation: networking: add OPEN Alliance 10BASE-T1x MAC-PHY serial interface
The IEEE 802.3cg project defines two 10 Mbit/s PHYs operating over a single pair of conductors. The 10BASE-T1L (Clause 146) is a long reach PHY supporting full duplex point-to-point operation over 1 km of single balanced pair of conductors. The 10BASE-T1S (Clause 147) is a short reach PHY supporting full / half duplex point-to-point operation over 15 m of single balanced pair of conductors, or half duplex multidrop bus operation over 25 m of single balanced pair of conductors. Furthermore, the IEEE 802.3cg project defines the new Physical Layer Collision Avoidance (PLCA) Reconciliation Sublayer (Clause 148) meant to provide improved determinism to the CSMA/CD media access method. PLCA works in conjunction with the 10BASE-T1S PHY operating in multidrop mode. The aforementioned PHYs are intended to cover the low-speed / low-cost applications in industrial and automotive environment. The large number of pins (16) required by the MII interface, which is specified by the IEEE 802.3 in Clause 22, is one of the major cost factors that need to be addressed to fulfil this objective. The MAC-PHY solution integrates an IEEE Clause 4 MAC and a 10BASE-T1x PHY exposing a low pin count Serial Peripheral Interface (SPI) to the host microcontroller. This also enables the addition of Ethernet functionality to existing low-end microcontrollers which do not integrate a MAC controller.

netdev: support binding dma-buf to netdevice
Add a netdev_dmabuf_binding struct which represents the dma-buf-to-netdevice binding. The netlink API will bind the dma-buf to rx queues on the netdevice. On the binding, the dma_buf_attach & dma_buf_map_attachment will occur. The entries in the sg_table from mapping will be inserted into a genpool to make it ready for allocation. The chunks in the genpool are owned by a dmabuf_chunk_owner struct which holds the dma-buf offset of the base of the chunk and the dma_addr of the chunk. Both are needed to use allocations that come from this chunk. We create a new type that represents an allocation from the genpool: net_iov. We setup the net_iov allocation size in the genpool to PAGE_SIZE for simplicity: to match the PAGE_SIZE normally allocated by the page pool and given to the drivers. The user can unbind the dmabuf from the netdevice by closing the netlink socket that established the binding. We do this so that the binding is automatically unbound even if the userspace process crashes. The binding and unbinding leaves an indicator in struct netdev_rx_queue that the given queue is bound, and the binding is actuated by resetting the rx queue using the queue API. The netdev_dmabuf_binding struct is refcounted, and releases its resources only when all the refs are released.

netlink: specs: mptcp: fix port endianness
The MPTCP port attribute is in host endianness, but was documented
as big-endian in the ynl specification.
Below are two examples from net/mptcp/pm_netlink.c showing that the
attribute is converted to/from host endianness for use with netlink.
Import from netlink:
addr->port = htons(nla_get_u16(tb[MPTCP_PM_ADDR_ATTR_PORT]))
Export to netlink:
nla_put_u16(skb, MPTCP_PM_ADDR_ATTR_PORT, ntohs(addr->port))
Where addr->port is defined as __be16.
No functional change intended.
Fixes:

mptcp: disable active MPTCP in case of blackhole
An MPTCP firewall blackhole can be detected if the following SYN retransmission after a fallback to "plain" TCP is accepted. In case of blackhole, a similar technique to the one in place with TFO is now used: MPTCP can be disabled for a certain period of time, 1h by default. This time period will grow exponentially when more blackhole issues get detected right after MPTCP is re-enabled and will reset to the initial value when the blackhole issue goes away. The blackhole period can be modified thanks to a new sysctl knob: blackhole_timeout. Two new MIB counters help understanding what's happening: - 'Blackhole', incremented when a blackhole is detected. - 'MPCapableSYNTXDisabled', incremented when an MPTCP connection directly falls back to TCP during the blackhole period. Because the technique is inspired by the one used by TFO, an important part of the new code is similar to what can find in tcp_fastopen.c, with some adaptations to the MPTCP case.

ARM: SoC fixes for 6.11, part 3
The bulk of the changes this time are for device tree files in the
rockchips platform, addressing correctness issues on individual
boards, plus one change in the rk356x SoC file to make it match
the binding.
The only other changes that came in are
- a CPU frequencey scaling fix for JH7110 (RISC-V)
- a build fix for the cznic hwrandom driver
- a fix for a deadlock in qualcomm uefi secure
application firmware driver

HW-Managed Flow Steering in mlx5 driver
Yevgeny Kliteynik says:
=======================
1. Overview
-----------
ConnectX devices support packet matching, modification, and redirection.
This functionality is referred as Flow Steering.
To configure a steering rule, the rule is written to the device-owned
memory. This memory is accessed and cached by the device when processing
a packet.
The first implementation of Flow Steering was done in FW, and it is
referred in the mlx5 driver as Device-Managed Flow Steering (DMFS).
Later we introduced SW-managed Flow Steering (SWS or SMFS), where the
driver is writing directly to the device's configuration memory (ICM)
through RC QP using RDMA operations (RDMA-read and RDAM-write), thus
achieving higher rates of rule insertion/deletion.
Now we introduce a new flow steering implementation: HW-Managed Flow
Steering (HWS or HMFS).
In this new approach, the driver is configuring steering rules directly
to the HW using the WQs with a special new type of WQE. This way we can
reach higher rule insertion/deletion rate with much lower CPU utilization
compared to SWS.
The key benefits of HWS as opposed to SWS:
+ HW manages the steering decision tree
- HW calculates CRC for each entry
- HW handles tree hash collisions
- HW & FW manage objects refcount
+ HW keeps cache coherency:
- HW provides tree access locking and synchronization
- HW provides notification on completion
+ Insertion rate isn’t affected by background traffic
- Dedicated HW components that handle insertion
2. Performance
--------------
Measuring Connection Tracking with simple IPv4 flows w/o NAT, we
are able to get ~5 times more flows offloaded per second using HWS.
3. Configuration
----------------
The enablement of HWS mode in eswitch manager is done using the same
devlink param that is already used for switching between FW-managed
steering and SW-managed steering modes:
# devlink dev param set pci/<PCI_ID> name flow_steering_mode cmod runtime value hmfs
4. Upstream Submission
----------------------
HWS support consists of 3 main components:
+ Steering:
- The lower layer that exposes HWS API to upper layers and implements
all the management of flow steering building blocks
+ FS-Core
- Implementation of fs_hws layer to enable fs_core to use HWS instead
of FW or SW steering
- Create HW steering action pools to utilize the ability of HWS to
share steering actions among different rules
- Add support for configuring HWS mode through devlink command,
similar to configuring SWS mode
+ Connection Tracking
- Implementation of CT support for HW steering
- Hooks up the CT ops for the new steering mode and uses the HWS API
to implement connection tracking.
Because of the large number of patches, we need to perform the submission
in several separate patch series. This series is the first submission that
lays the ground work for the next submissions, where an actual user of HWS
will be added.
5. Patches in this series

dt-bindings: net: tja11xx: fix the broken binding
As Rob pointed in another mail thread [1], the binding of tja11xx PHY
is completely broken, the schema cannot catch the error in the DTS. A
compatiable string must be needed if we want to add a custom propety.
So extract known PHY IDs from the tja11xx PHY drivers and convert them
into supported compatible string list to fix the broken binding issue.

net-timestamp: introduce SOF_TIMESTAMPING_OPT_RX_FILTER flag
introduce a new flag SOF_TIMESTAMPING_OPT_RX_FILTER in the receive path. User can set it with SOF_TIMESTAMPING_SOFTWARE to filter out rx software timestamp report, especially after a process turns on netstamp_needed_key which can time stamp every incoming skb. Previously, we found out if an application starts first which turns on netstamp_needed_key, then another one only passing SOF_TIMESTAMPING_SOFTWARE could also get rx timestamp. Now we handle this case by introducing this new flag without breaking users. Quoting Willem to explain why we need the flag: "why a process would want to request software timestamp reporting, but not receive software timestamp generation. The only use I see is when the application does request SOF_TIMESTAMPING_SOFTWARE | SOF_TIMESTAMPING_TX_SOFTWARE." Similarly, this new flag could also be used for hardware case where we can set it with SOF_TIMESTAMPING_RAW_HARDWARE, then we won't receive hardware receive timestamp. Another thing about errqueue in this patch I have a few words to say: In this case, we need to handle the egress path carefully, or else reporting the tx timestamp will fail. Egress path and ingress path will finally call sock_recv_timestamp(). We have to distinguish them. Errqueue is a good indicator to reflect the flow direction.

RISC-V Fixes for 6.11-rc7
