bonding: Fix unnecessary warnings and logs from bond_xdp_get_xmit_slave()
syzbot reported a WARNING in bond_xdp_get_xmit_slave. To reproduce
this[1], one bond device (bond1) has xdpdrv, which increases
bpf_master_redirect_enabled_key. Another bond device (bond0) which is
unsupported by XDP but its slave (veth3) has xdpgeneric that returns
XDP_TX. This triggers WARN_ON_ONCE() from the xdp_master_redirect().
To reduce unnecessary warnings and improve log management, we need to
delete the WARN_ON_ONCE() and add ratelimit to the netdev_err().
[1] Steps to reproduce:
# Needs tx_xdp with return XDP_TX;
ip l add veth0 type veth peer veth1
ip l add veth3 type veth peer veth4
ip l add bond0 type bond mode 6 # BOND_MODE_ALB, unsupported by XDP
ip l add bond1 type bond # BOND_MODE_ROUNDROBIN by default
ip l set veth0 master bond1
ip l set bond1 up
# Increases bpf_master_redirect_enabled_key
ip l set dev bond1 xdpdrv object tx_xdp.o section xdp_tx
ip l set veth3 master bond0
ip l set bond0 up
ip l set veth4 up
# Triggers WARN_ON_ONCE() from the xdp_master_redirect()
ip l set veth3 xdpgeneric object tx_xdp.o section xdp_tx

fuse: use exclusive lock when FUSE_I_CACHE_IO_MODE is set
This may be a typo. The comment has said shared locks are
not allowed when this bit is set. If using shared lock, the
wait in `fuse_file_cached_io_open` may be forever.

Merge branch 'fix-maximum-tx-rx-frame-sizes-in-ravb-driver'
Paul Barker says:
====================
Fix maximum TX/RX frame sizes in ravb driver
These patches fix a couple of bugs in the maximum supported TX/RX frame
sizes in the ravb driver.
* For the GbEth IP, we were advertising a maximum TX frame size/MTU
that was larger that the maximum the hardware can transmit.
* For the R-Car AVB IP, we were unnecessarily setting the maximum RX
frame size/MRU based on the MTU, which by default is smaller than
the maximum the hardware can receive.
For the R-Car AVB IP, the maximum TX frame size should be 2047 (not
2048), but additional work will be required to validate that change so
it is not included in this series.
Changes v2->v3:
* Pick up Reviewed-by tag and suggested comment improvement from
Niklas.
Changes v1->v2:
* Rebase on net tree as these are both bugfixes.
* Pick up Reviewed-by tags.

net: ravb: Fix R-Car RX frame size limit
The RX frame size limit should not be based on the current MTU setting.
Instead it should be based on the hardware capabilities.
While we're here, improve the description of the receive frame length
setting as suggested by Niklas.

net: ravb: Fix maximum TX frame size for GbEth devices
The datasheets for all SoCs using the GbEth IP specify a maximum
transmission frame size of 1.5 kByte. I've confirmed through internal
discussions that support for 1522 byte frames has been validated, which
allows us to support the default MTU of 1500 bytes after reserving space
for the Ethernet header, frame checksums and an optional VLAN tag.

mac802154: Fix potential RCU dereference issue in mac802154_scan_worker
In the `mac802154_scan_worker` function, the `scan_req->type` field was
accessed after the RCU read-side critical section was unlocked. According
to RCU usage rules, this is illegal and can lead to unpredictable
behavior, such as accessing memory that has been updated or causing
use-after-free issues.
This possible bug was identified using a static analysis tool developed
by myself, specifically designed to detect RCU-related issues.
To address this, the `scan_req->type` value is now stored in a local
variable `scan_req_type` while still within the RCU read-side critical
section. The `scan_req_type` is then used after the RCU lock is released,
ensuring that the type value is safely accessed without violating RCU
rules.

RTL8125 added fields to the tally counter, what may result in the chip
dma'ing these new fields to unallocated memory. Therefore make sure
that the allocated memory area is big enough to hold all of the
tally counter values, even if we use only parts of it.

net: qrtr: Update packets cloning when broadcasting
When broadcasting data to multiple nodes via MHI, using skb_clone()
causes all nodes to receive the same header data. This can result in
packets being discarded by endpoints, leading to lost data.
This issue occurs when a socket is closed, and a QRTR_TYPE_DEL_CLIENT
packet is broadcasted. All nodes receive the same destination node ID,
causing the node connected to the client to discard the packet and
remain unaware of the client's deletion.
Replace skb_clone() with pskb_copy(), to create a separate copy of
the header for each sk_buff.

The core clk framework is left largely untouched this time around except for
support for the newly ratified DT property 'assigned-clock-rates-u64'. I'm much
more excited about the support for loading DT overlays from KUnit tests so that
we can test how the clk framework parses DT nodes during clk registration. The
clk framework has some places that are highly DeviceTree dependent so this
charts the path to extend the KUnit tests to cover even more framework code in
the future. I've got some more tests on the list that use the DT overlay
support, but they uncovered issues with clk unregistration that I'm still
working on fixing.
Outside the core, the clk driver update pile is dominated by Qualcomm and
Renesas SoCs, making it fairly usual. Looking closer, there are fixes for
things all over the place, like adding missing clk frequencies or moving
defines for the number of clks out of DT binding headers into the drivers.
There are even conversions of DT bindings to YAML and migration away from
strings to describe clk topology. Overall it doesn't look unusual so I expect
the new drivers to be where we'll have fixes in the coming weeks.

i2c-for-6.12-rc1
I2C core
========
After 15 years of deprecation, the I2C_COMPAT symbol has finally been
removed. Also client addresses are now locked during initialization to
prevent race conditions between different kinds of instantiation. Scoped
foreach OF child loops are now used. And the testunit has received some
cleanups and documentation improvements as well as two new tests, one
for repeated start and one for triggering SMBusAlert interrupts.
I2C host drivers
================
The DesignWare and the Renesas I2C drivers have received most of
the changes in this pull request.
The first has has undergone through a series of cleanups that
have been sent to the mailing list a year ago for the first time
and finally get merged in this pull request. They are many, from
typos (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move
inline functions to librarieas) and many others.
Besides that, all the DesignWare Kconfig options have been
grouped under the I2C_DESIGNWARE_CORE and this required some
adaptation in many of the kernel configuration files for
different arm and mips boards.
Follows the list of the rest of the changes grouped by type of
change.
Cleanups
--------
The Qualcomm Geni platform improves the exit path in the runtime
resume function.
The Intel LJCA driver loses "target_addr" parameter in
ljca_i2c_stop() because it was unused.
The MediaTek controller intializes the restart_flag in the
transfer function using the ternary conditional operator ("? :")
instead of initializing it in different parts.
Constified a few global data structures in the virtio driver.
The Renesas driver simplifies the bus speed handling in the init
function making it more readable.
Improved an if/else statement in probe function of the Renesas
R-Car driver.
The iMX/MXC driver switches to using the RUNTIME_PM_OPS() instead
of SET_RUNTIME_PM_OPS().
Still in the iMX/MXC driver a comma ',' has been replaced by a
semicolon ';', while in different drivers the ',' has been
removed from the '{ }' delimiters.
Finally three devm_clk_get_enabled() have been used to simplify
the devm_clk_get/clk_prepare_enable tuple in the Renesas EMEV2,
Ingenic and MPC drivers.
Refactors
---------
The Nuvoton fixes a potential out of boundary array access. This
is not a bug fix because the issue could never occur due to
hardware not having the properties listed in the array. The
change makes the driver more future proof and, at the same time,
silences code analyzers.
Improvements
------------
The Renesas I2C (riic) driver undergoes several patches improving
the runtime power management handling.
The Intel i801 driver uses a more descriptive adapter's name to
show the presence of the IDF feature.
In the Intel Denverton (ismt) adapter the pending transactions
are killed when irq's can't complete their handling, triggering a
timeout. This could have been considered as a bug fix, but
because, standing to Vasily, it's very sporadic, I preferred
considering the patch rather as an improvement.
New Feature
-----------
The Renesas I2C (riic) driver now supports the fast mode plus.
New support
-----------
Added support for:
- Renesas R9A08G045
- Rockchip RK3576
- KEBA I2C
- Theobroma Systems Mule Multiplexer.
The Keba comes with a new driver, i2c-keba.c.
The Mule is an i2c multiplexer and it also comes with a new
driver, mux/i2c-mux-mule.c.
Core patch
----------
This pull request includes also a patch in the I2C framework, in
i2c-core-base.c where the runtime PM functions have been replaced
in order to allow to be accessed during the device add.
Devicetree
----------
Some cleanups in the devicetree, as well. nVidia and Qualcomm
bindings improve their "if:then:" blocks. While the aspeed
binding loses the "multi-master" property because it was
redundant.
The i2c-sprd binding has been converted to YAML.

Pull i2c updates from Wolfram Sang:
"I2C core:
- finally remove the I2C_COMPAT symbol after 15 years of deprecation
- lock client addresses during initialization to prevent race
conditions between different kinds of instantiation
- use scoped foreach OF child loops
- testunit cleanups and documentation improvements, as well as two
new tests, one for repeated start and one for triggering SMBusAlert
interrupts
I2C host drivers:
- DesignWare and Renesas I2C driver updates.
The first has has undergone through a series of cleanups that have
been sent to the mailing list a year ago for the first time and
finally get merged in this pull request. They are many, from typos
(e.g. i2/i2c), to cosmetics, to refactoring (e.g. move inline
functions to librarieas) and many others.
- all the DesignWare Kconfig options have been grouped under the
I2C_DESIGNWARE_CORE and this required some adaptation in many of
the kernel configuration files for different arm and mips boards
Cleanups:
- improve the exit path in the runtime resume function for the
Qualcomm Geni platform
- get rid of the unused "target_addr" parameter in the Intel LJCA
driver
- intialize the restart_flag in the MediaTek controller in one single
place
- constify a few global data structures in the virtio driver
- simplify the bus speed handling in the Renesas driver init function
making it more readable
- improved probe function of the Renesas R-Car driver
- switch the iMX/MXC driver to use RUNTIME_PM_OPS() instead of
SET_RUNTIME_PM_OPS()
- iMX/MXC driver cleanups
- use devm_clk_get_enabled() to simplify the Renesas EMEV2, Ingenic
and MPC drivers
Refactoring:
- Fix a potential out of boundary array access in the Nuvoton driver.
This is not a bug fix because the issue could never occur due to
hardware not having the properties listed in the array. The change
makes the driver more future proof and, at the same time, silences
code analyzers.

- several patches improving the runtime power management handling of

firewire updates for v6.12
The batch of changes includes the followwing:
- Replacing tasklet with usual workqueue for isochronous context
- Replacing IDR with XArray
- Utilizing guard macro where possible
- Printing deprecation warning when enabling debug parameter of
firewire-ohci module
Additionally, it includes a single patch for sound subsystem which the
subsystem maintainer acked:
- Switching to nonatomic PCM operation
In FireWire subsystem, tasklet has been used as the bottom half of 1394
OHCi hardIRQ so long. In the recent kernel updates, BH workqueue has
been available, and some developers have proposed replacing tasklet with
BH workqueue. While it is fortunate that developers are still considering
the legacy subsystem, a simple replacement is not necessarily suitable.
As a first step towards dropping tasklet, I've investigated the
feasibility for 1394 OHCI isochronous context, and concluded that usual
workqueue is available. In the context, the batch of packets is processed
in the specific queue, thus the timing jitter caused by task scheduling is
not so critical. Additionally, DMA transmission can be scheduled
per-packet basis, therefore the context can be sleep between the operation
of transmissions. Furthermore, in-kernel protocol implementation involves
some CPU-bound tasks, which can sometimes consumes CPU time so long. These
characteristics suggest that usual workqueue is suitable, through BH
workqueues are not.
The replacement with usual workqueue allows unit drivers to process the
content of packets in non-atomic context. It brings some reliefs to some
drivers in sound subsystem that spin-lock is not mandatory anymore during
isochronous packet processing.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Wait for device readiness after reset by polling Vendor ID and
looking for Configuration RRS instead of polling the Command
register and looking for non-error completions, to avoid hardware
retries done for RRS on non-Vendor ID reads (Bjorn Helgaas)
- Rename CRS Completion Status to RRS ('Request Retry Status') to
match PCIe r6.0 spec usage (Bjorn Helgaas)
- Clear LBMS bit after a manual link retrain so we don't try to
retrain a link when there's no downstream device anymore (Maciej W.
Rozycki)
- Revert to the original link speed after retraining fails instead of
leaving it restricted to 2.5GT/s, so a future device has a chance
to use higher speeds (Maciej W. Rozycki)
- Wait for each level of downstream bus, not just the first, to
become accessible before restoring devices on that bus (Ilpo
Järvinen)
- Add ARCH_PCI_DEV_GROUPS so s390 can add its own attribute_groups
without having to stomp on the core's pdev->dev.groups (Lukas
Wunner)
Driver binding:
- Export pcim_request_region(), a managed counterpart of
pci_request_region(), for use by drivers (Philipp Stanner)
- Export pcim_iomap_region() and deprecate pcim_iomap_regions()
(Philipp Stanner)
- Request the PCI BAR used by xboxvideo (Philipp Stanner)
- Request and map drm/ast BARs with pcim_iomap_region() (Philipp
Stanner)
MSI:
- Add MSI_FLAG_NO_AFFINITY flag for devices that mux MSIs onto a
single IRQ line and cannot set the affinity of each MSI to a
specific CPU core (Marek Vasut)
- Use MSI_FLAG_NO_AFFINITY and remove unnecessary .irq_set_affinity()
implementations in aardvark, altera, brcmstb, dwc, mediatek-gen3,
mediatek, mobiveil, plda, rcar, tegra, vmd, xilinx-nwl,
xilinx-xdma, and xilinx drivers to avoid 'IRQ: set affinity failed'
warnings (Marek Vasut)
Power management:
- Add pwrctl support for ATH11K inside the WCN6855 package (Konrad
Dybcio)
PCI device hotplug:
- Remove unnecessary hpc_ops struct from shpchp (ngn)
- Check for PCI_POSSIBLE_ERROR(), not 0xffffffff, in cpqphp
(weiyufeng)
Virtualization:
- Mark Creative Labs EMU20k2 INTx masking as broken (Alex Williamson)
- Add an ACS quirk for Qualcomm SA8775P, which doesn't advertise ACS
but does provide ACS-like features (Subramanian Ananthanarayanan)
IOMMU:
- Add function 0 DMA alias quirk for Glenfly Arise audio function,
which uses the function 0 Requester ID (WangYuli)
NPEM:
- Add Native PCIe Enclosure Management (NPEM) support for sysfs
control of NVMe RAID storage indicators (ok/fail/locate/
rebuild/etc) (Mariusz Tkaczyk)
- Add support for the ACPI _DSM PCIe SSD status LED management, which
is functionally similar to NPEM but mediated by platform firmware
(Mariusz Tkaczyk)
Device trees:
- Drop minItems and maxItems from ranges in PCI generic host binding
since host bridges may have several MMIO and I/O port apertures
(Frank Li)
- Add kirin, rcar-gen2, uniphier DT binding top-level constraints for
clocks (Krzysztof Kozlowski)
Altera PCIe controller driver:
- Convert altera DT bindings from text to YAML (Matthew Gerlach)
- Replace TLP_REQ_ID() with macro PCI_DEVID(), which does the same
thing and is what other drivers use (Jinjie Ruan)
Broadcom STB PCIe controller driver:
- Add DT binding maxItems for reset controllers (Jim Quinlan)
- Use the 'bridge' reset method if described in the DT (Jim Quinlan)
- Use the 'swinit' reset method if described in the DT (Jim Quinlan)
- Add 'has_phy' so the existence of a 'rescal' reset controller
doesn't imply software control of it (Jim Quinlan)
- Add support for many inbound DMA windows (Jim Quinlan)
- Rename SoC 'type' to 'soc_base' express the fact that SoCs come in
families of multiple similar devices (Jim Quinlan)
- Add Broadcom 7712 DT description and driver support (Jim Quinlan)
- Sort enums, pcie_offsets[], pcie_cfg_data, .compatible strings for
maintainability (Bjorn Helgaas)
Freescale i.MX6 PCIe controller driver:
- Add imx6q-pcie 'dbi2' and 'atu' reg-names for i.MX8M Endpoints
(Richard Zhu)
- Fix a code restructuring error that caused i.MX8MM and i.MX8MP
Endpoints to fail to establish link (Richard Zhu)
- Fix i.MX8MP Endpoint occasional failure to trigger MSI by enforcing
outbound alignment requirement (Richard Zhu)
- Call phy_power_off() in the .probe() error path (Frank Li)
- Rename internal names from imx6_* to imx_* since i.MX7/8/9 are also
supported (Frank Li)
- Manage Refclk by using SoC-specific callbacks instead of switch
statements (Frank Li)
- Manage core reset by using SoC-specific callbacks instead of switch
statements (Frank Li)
- Expand comments for erratum ERR010728 workaround (Frank Li)
- Use generic PHY APIs to configure mode, speed, and submode, which

nfs: add "NFS Client and Server Interlock" section to localio.rst
This section answers a new FAQ entry: 9. How does LOCALIO make certain that object lifetimes are managed properly given NFSD and NFS operate in different contexts? See the detailed "NFS Client and Server Interlock" section below. The first half of the section details NeilBrown's elegant design for LOCALIO's nfs_uuid_t based interlock and is heavily based on Neil's "net namespace refcounting" description here: https://marc.info/?l=linux-nfs&m=172498546024767&w=2 The second half of the section details the per-cpu-refcount introduced to ensure NFSD's nfsd_serv isn't destroyed while in use by a LOCALIO client.

This document gives an overview of the LOCALIO auxiliary RPC protocol added to the Linux NFS client and server to allow them to reliably handshake to determine if they are on the same host. Once an NFS client and server handshake as "local", the client will bypass the network RPC protocol for read, write and commit operations. Due to this XDR and RPC bypass, these operations will operate faster.

nfs: implement client support for NFS_LOCALIO_PROGRAM
The LOCALIO auxiliary RPC protocol consists of a single "UUID_IS_LOCAL" RPC method that allows the Linux NFS client to verify the local Linux NFS server can see the nonce (single-use UUID) the client generated and made available in nfs_common for subsequent lookup and verification by the NFS server. If matched, the NFS server populates members in the nfs_uuid_t struct. The NFS client then transfers these nfs_uuid_t struct member pointers to the nfs_client struct and cleans up the nfs_uuid_t struct. See: fs/nfs/localio.c:nfs_local_probe() This protocol isn't part of an IETF standard, nor does it need to be considering it is Linux-to-Linux auxiliary RPC protocol that amounts to an implementation detail. Localio is only supported when UNIX-style authentication (AUTH_UNIX, aka AUTH_SYS) is used (enforced by fs/nfs/localio.c:nfs_local_probe()). The UUID_IS_LOCAL method encodes the client generated uuid_t in terms of the fixed UUID_SIZE (16 bytes). The fixed size opaque encode and decode XDR methods are used instead of the less efficient variable sized methods. Having a nonce (single-use uuid) is better than using the same uuid for the life of the server, and sending it proactively by client rather than reactively by the server is also safer.

nfs/localio: use dedicated workqueues for filesystem read and write
For localio access, don't call filesystem read() and write() routines directly. This solves two problems: 1) localio writes need to use a normal (non-memreclaim) unbound workqueue. This avoids imposing new requirements on how underlying filesystems process frontend IO, which would cause a large amount of work to update all filesystems. Without this change, when XFS starts getting low on space, XFS flushes work on a non-memreclaim work queue, which causes a priority inversion problem: 00573 workqueue: WQ_MEM_RECLAIM writeback:wb_workfn is flushing !WQ_MEM_RECLAIM xfs-sync/vdc:xfs_flush_inodes_worker 00573 WARNING: CPU: 6 PID: 8525 at kernel/workqueue.c:3706 check_flush_dependency+0x2a4/0x328 00573 Modules linked in: 00573 CPU: 6 PID: 8525 Comm: kworker/u71:5 Not tainted 6.10.0-rc3-ktest-00032-g2b0a133403ab #18502 00573 Hardware name: linux,dummy-virt (DT) 00573 Workqueue: writeback wb_workfn (flush-0:33) 00573 pstate: 400010c5 (nZcv daIF -PAN -UAO -TCO -DIT +SSBS BTYPE=--) 00573 pc : check_flush_dependency+0x2a4/0x328 00573 lr : check_flush_dependency+0x2a4/0x328 00573 sp : ffff0000c5f06bb0 00573 x29: ffff0000c5f06bb0 x28: ffff0000c998a908 x27: 1fffe00019331521 00573 x26: ffff0000d0620900 x25: ffff0000c5f06ca0 x24: ffff8000828848c0 00573 x23: 1fffe00018be0d8e x22: ffff0000c1210000 x21: ffff0000c75fde00 00573 x20: ffff800080bfd258 x19: ffff0000cad63400 x18: ffff0000cd3a4810 00573 x17: 0000000000000000 x16: 0000000000000000 x15: ffff800080508d98 00573 x14: 0000000000000000 x13: 204d49414c434552 x12: 1fffe0001b6eeab2 00573 x11: ffff60001b6eeab2 x10: dfff800000000000 x9 : ffff60001b6eeab3 00573 x8 : 0000000000000001 x7 : 00009fffe491154e x6 : ffff0000db775593 00573 x5 : ffff0000db775590 x4 : ffff0000db775590 x3 : 0000000000000000 00573 x2 : 0000000000000027 x1 : ffff600018be0d62 x0 : dfff800000000000 00573 Call trace: 00573 check_flush_dependency+0x2a4/0x328 00573 __flush_work+0x184/0x5c8 00573 flush_work+0x18/0x28 00573 xfs_flush_inodes+0x68/0x88 00573 xfs_file_buffered_write+0x128/0x6f0 00573 xfs_file_write_iter+0x358/0x448 00573 nfs_local_doio+0x854/0x1568 00573 nfs_initiate_pgio+0x214/0x418 00573 nfs_generic_pg_pgios+0x304/0x480 00573 nfs_pageio_doio+0xe8/0x240 00573 nfs_pageio_complete+0x160/0x480 00573 nfs_writepages+0x300/0x4f0 00573 do_writepages+0x12c/0x4a0 00573 __writeback_single_inode+0xd4/0xa68 00573 writeback_sb_inodes+0x470/0xcb0 00573 __writeback_inodes_wb+0xb0/0x1d0 00573 wb_writeback+0x594/0x808 00573 wb_workfn+0x5e8/0x9e0 00573 process_scheduled_works+0x53c/0xd90 00573 worker_thread+0x370/0x8c8 00573 kthread+0x258/0x2e8 00573 ret_from_fork+0x10/0x20 2) Some filesystem writeback routines can end up taking up a lot of stack space (particularly XFS). Instead of risking running over due to the extra overhead from the NFS stack, we should just call these routines from a workqueue job. Since we need to do this to address 1) above we're able to avoid possibly blowing the stack "for free". Use of dedicated workqueues improves performance over using the system_unbound_wq. Also, the creds used to open the file are used to override_creds() in both nfs_local_call_read() and nfs_local_call_write() -- otherwise the workqueue could have elevated capabilities (which the caller may not). Lastly, care is taken to set PF_LOCAL_THROTTLE | PF_MEMALLOC_NOIO in nfs_do_local_write() to avoid writeback deadlocks. The PF_LOCAL_THROTTLE flag prevents deadlocks in balance_dirty_pages() by causing writes to only be throttled against other writes to the same bdi (it keeps the throttling local). Normally all writes to bdi(s) are throttled equally (after throughput factors are allowed for). The PF_MEMALLOC_NOIO flag prevents the lower filesystem IO from causing memory reclaim to re-enter filesystems or IO devices and so prevents deadlocks from occuring where IO that cleans pages is waiting on IO to complete.

nfs: add LOCALIO support
Add client support for bypassing NFS for localhost reads, writes, and commits. This is only useful when the client and the server are running on the same host. nfs_local_probe() is stubbed out, later commits will enable client and server handshake via a Linux-only LOCALIO auxiliary RPC protocol. This has dynamic binding with the nfsd module (via nfs_localio module which is part of nfs_common). LOCALIO will only work if nfsd is already loaded. The "localio_enabled" nfs kernel module parameter can be used to disable and enable the ability to use LOCALIO support. CONFIG_NFS_LOCALIO enables NFS client support for LOCALIO. Lastly, LOCALIO uses an nfsd_file to initiate all IO. To make proper use of nfsd_file (and nfsd's filecache) its lifetime (duration before nfsd_file_put is called) must extend until after commit, read and write operations. So rather than immediately drop the nfsd_file reference in nfs_local_open_fh(), that doesn't happen until nfs_local_pgio_release() for read/write and not until nfs_local_release_commit_data() for commit. The same applies to the reference held on nfsd's nn->nfsd_serv. Both objects' lifetimes and associated references are managed through calls to nfs_to->nfsd_file_put_local().

nfsd: add LOCALIO support
Add server support for bypassing NFS for localhost reads, writes, and commits. This is only useful when both the client and server are running on the same host. If nfsd_open_local_fh() fails then the NFS client will both retry and fallback to normal network-based read, write and commit operations if localio is no longer supported. Care is taken to ensure the same NFS security mechanisms are used (authentication, etc) regardless of whether localio or regular NFS access is used. The auth_domain established as part of the traditional NFS client access to the NFS server is also used for localio. Store auth_domain for localio in nfsd_uuid_t and transfer it to the client if it is local to the server. Relative to containers, localio gives the client access to the network namespace the server has. This is required to allow the client to access the server's per-namespace nfsd_net struct. This commit also introduces the use of NFSD's percpu_ref to interlock nfsd_destroy_serv and nfsd_open_local_fh, to ensure nn->nfsd_serv is not destroyed while in use by nfsd_open_local_fh and other LOCALIO client code.

The next commit will introduce nfsd_open_local_fh() which returns an nfsd_file structure. This commit exposes LOCALIO's required NFSD symbols to the NFS client: - Make nfsd_open_local_fh() symbol and other required NFSD symbols available to NFS in a global 'nfs_to' nfsd_localio_operations struct (global access suggested by Trond, nfsd_localio_operations suggested by NeilBrown). The next commit will also introduce nfsd_localio_ops_init() that init_nfsd() will call to initialize 'nfs_to'. - Introduce nfsd_file_file() that provides access to nfsd_file's backing file. Keeps nfsd_file structure opaque to NFS client (as suggested by Jeff Layton). - Introduce nfsd_file_put_local() that will put the reference to the nfsd_file's associated nn->nfsd_serv and then put the reference to the nfsd_file (as suggested by NeilBrown).

nfs_common: add NFS LOCALIO auxiliary protocol enablement
fs/nfs_common/nfslocalio.c provides interfaces that enable an NFS client to generate a nonce (single-use UUID) and associated nfs_uuid_t struct, register it with nfs_common for subsequent lookup and verification by the NFS server and if matched the NFS server populates members in the nfs_uuid_t struct. nfs_common's nfs_uuids list is the basis for localio enablement, as such it has members that point to nfsd memory for direct use by the client (e.g. 'net' is the server's network namespace, through it the client can access nn->nfsd_serv). This commit also provides the base nfs_uuid_t interfaces to allow proper net namespace refcounting for the LOCALIO use case. CONFIG_NFS_LOCALIO controls the nfs_common, NFS server and NFS client enablement for LOCALIO. If both NFS_FS=m and NFSD=m then NFS_COMMON_LOCALIO_SUPPORT=m and nfs_localio.ko is built (and provides nfs_common's LOCALIO support). # lsmod | grep nfs_localio nfs_localio 12288 2 nfsd,nfs sunrpc 745472 35 nfs_localio,nfsd,auth_rpcgss,lockd,nfsv3,nfs Signed-off-by: Mike Snitzer <snitzer@kernel.org> Co-developed-by: NeilBrown <neilb@suse.de> Signed-off-by: NeilBrown <neilb@suse.de> Reviewed-by: Jeff Layton <jlayton@kernel.org> Signed-off-by: Anna Schumaker <anna.schumaker@oracle.com> |

SUNRPC: add svcauth_map_clnt_to_svc_cred_local
Add new funtion svcauth_map_clnt_to_svc_cred_local which maps a generic cred to a svc_cred suitable for use in nfsd. This is needed by the localio code to map nfs client creds to nfs server credentials. Following from net/sunrpc/auth_unix.c:unx_marshal() it is clear that ->fsuid and ->fsgid must be used (rather than ->uid and ->gid). In addition, these uid and gid must be translated with from_kuid_munged() so local client uses correct uid and gid when acting as local server. Jeff Layton noted: This is where the magic happens. Since we're working in kuid_t/kgid_t, we don't need to worry about further idmapping.

SUNRPC: remove call_allocate() BUG_ONs
Remove BUG_ON if p_arglen=0 to allow RPC with void arg.
Remove BUG_ON if p_replen=0 to allow RPC with void return.
The former was needed for the first revision of the LOCALIO protocol
which had an RPC that took a void arg:
/* raw RFC 9562 UUID */
typedef u8 uuid_t<UUID_SIZE>;
program NFS_LOCALIO_PROGRAM {
version LOCALIO_V1 {
void
NULL(void) = 0;
uuid_t
GETUUID(void) = 1;
} = 1;
} = 400122;
The latter is needed for the final revision of the LOCALIO protocol
which has a UUID_IS_LOCAL RPC which returns a void:
/* raw RFC 9562 UUID */
typedef u8 uuid_t<UUID_SIZE>;
program NFS_LOCALIO_PROGRAM {
version LOCALIO_V1 {
void
NULL(void) = 0;
void
UUID_IS_LOCAL(uuid_t) = 1;
} = 1;
} = 400122;
There is really no value in triggering a BUG_ON in response to either
of these previously unsupported conditions.
NeilBrown would like the entire 'if (proc->p_proc != 0)' branch
removed (not just the one BUG_ON that must be removed for LOCALIO's
immediate needs of returning void).

nfsd: add nfsd_serv_try_get and nfsd_serv_put
Introduce nfsd_serv_try_get and nfsd_serv_put and update the nfsd code to prevent nfsd_destroy_serv from destroying nn->nfsd_serv until any caller of nfsd_serv_try_get releases their reference using nfsd_serv_put. A percpu_ref is used to implement the interlock between nfsd_destroy_serv and any caller of nfsd_serv_try_get. This interlock is needed to properly wait for the completion of client initiated localio calls to nfsd (that are _not_ in the context of nfsd).

nfsd: add nfsd_file_acquire_local()
nfsd_file_acquire_local() can be used to look up a file by filehandle without having a struct svc_rqst. This can be used by NFS LOCALIO to allow the NFS client to bypass the NFS protocol to directly access a file provided by the NFS server which is running in the same kernel. In nfsd_file_do_acquire() care is taken to always use fh_verify() if rqstp is not NULL (as is the case for non-LOCALIO callers). Otherwise the non-LOCALIO callers will not supply the correct and required arguments to __fh_verify (e.g. gssclient isn't passed). Introduce fh_verify_local() wrapper around __fh_verify to make it clear that LOCALIO is intended caller. Also, use GC for nfsd_file returned by nfsd_file_acquire_local. GC offers performance improvements if/when a file is reopened before launderette cleans it from the filecache's LRU.

nfsd: factor out __fh_verify to allow NULL rqstp to be passed
__fh_verify() offers an interface like fh_verify() but doesn't require a struct svc_rqst *, instead it also takes the specific parts as explicit required arguments. So it is safe to call __fh_verify() with a NULL rqstp, but the net, cred, and client args must not be NULL. __fh_verify() does not use SVC_NET(), nor does the functions it calls. Rather than using rqstp->rq_client pass the client and gssclient explicitly to __fh_verify and then to nfsd_set_fh_dentry(). Lastly, it should be noted that the previous commit prepared for 4 associated tracepoints to only be used if rqstp is not NULL (this is a stop-gap that should be properly fixed so localio also benefits from the utility these tracepoints provide when debugging fh_verify issues).

NFSD: Short-circuit fh_verify tracepoints for LOCALIO
LOCALIO will be able to call fh_verify() with a NULL rqstp. In this case, the existing trace points need to be skipped because they want to dereference the address fields in the passed-in rqstp. Temporarily make these trace points conditional to avoid a seg fault in this case. Putting the "rqstp != NULL" check in the trace points themselves makes the check more efficient.

NFSD: Avoid using rqstp->rq_vers in nfsd_set_fh_dentry()
Currently, fh_verify() makes some daring assumptions about which version of file handle the caller wants, based on the things it can find in the passed-in rqstp. The about-to-be-introduced LOCALIO use case sometimes has no svc_rqst context, so this logic won't work in that case. Instead, examine the passed-in file handle. It's .max_size field should carry information to allow nfsd_set_fh_dentry() to initialize the file handle appropriately. The file handle used by lockd and the one created by write_filehandle never need any of the version-specific fields (which affect things like write and getattr requests and pre/post attributes).
