Pablo Neira Ayuso says:
====================
Netfilter fixes for net
v2: with kdoc fixes per Paolo Abeni.
The following patchset contains Netfilter fixes for net:
Patch #1 and #2 handle an esoteric scenario: Given two tasks sending UDP
packets to one another, two packets of the same flow in each direction
handled by different CPUs that result in two conntrack objects in NEW
state, where reply packet loses race. Then, patch #3 adds a testcase for
this scenario. Series from Florian Westphal.
1) NAT engine can falsely detect a port collision if it happens to pick
up a reply packet as NEW rather than ESTABLISHED. Add extra code to
detect this and suppress port reallocation in this case.
2) To complete the clash resolution in the reply direction, extend conntrack
logic to detect clashing conntrack in the reply direction to existing entry.
3) Adds a test case.
Then, an assorted list of fixes follow:
4) Add a selftest for tproxy, from Antonio Ojea.
5) Guard ctnetlink_*_size() functions under
#if defined(CONFIG_NETFILTER_NETLINK_GLUE_CT) || defined(CONFIG_NF_CONNTRACK_EVENTS)
From Andy Shevchenko.
6) Use -m socket --transparent in iptables tproxy documentation.
From XIE Zhibang.
7) Call kfree_rcu() when releasing flowtable hooks to address race with
netlink dump path, from Phil Sutter.
8) Fix compilation warning in nf_reject with CONFIG_BRIDGE_NETFILTER=n.
From Simon Horman.
9) Guard ctnetlink_label_size() under CONFIG_NF_CONNTRACK_EVENTS which
is its only user, to address a compilation warning. From Simon Horman.
10) Use rcu-protected list iteration over basechain hooks from netlink
dump path.
11) Fix memcg for nf_tables, use GFP_KERNEL_ACCOUNT is not complete.
12) Remove old nfqueue conntrack clash resolution. Instead trying to
use same destination address consistently which requires double DNAT,
use the existing clash resolution which allows clashing packets
go through with different destination. Antonio Ojea originally
reported an issue from the postrouting chain, I proposed a fix:
https://lore.kernel.org/netfilter-devel/ZuwSwAqKgCB2a51-@calendula/T/
which he reported it did not work for him.
13) Adds a selftest for patch 12.
14) Fixes ipvs.sh selftest.

For historical reasons there are two clash resolution spots in
netfilter, one in nfnetlink_queue and one in conntrack core.
nfnetlink_queue one was added first: If a colliding entry is found, NAT
NAT transformation is reversed by calling nat engine again with altered
tuple.
See commit 368982cd7d1b ("netfilter: nfnetlink_queue: resolve clash for
unconfirmed conntracks") for details.
One problem is that nf_reroute() won't take an action if the queueing
doesn't occur in the OUTPUT hook, i.e. when queueing in forward or
postrouting, packet will be sent via the wrong path.
Another problem is that the scenario addressed (2nd UDP packet sent with
identical addresses while first packet is still being processed) can also
occur without any nfqueue involvement due to threaded resolvers doing
A and AAAA requests back-to-back.
This lead us to add clash resolution logic to the conntrack core, see
commit 6a757c07e51f ("netfilter: conntrack: allow insertion of clashing
entries"). Instead of fixing the nfqueue based logic, lets remove it
and let conntrack core handle this instead.
Retain the ->update hook for sake of nfqueue based conntrack helpers.
We could axe this hook completely but we'd have to split confirm and
helper logic again, see commit ee04805ff54a ("netfilter: conntrack: make
conntrack userspace helpers work again").
This SHOULD NOT be backported to kernels earlier than v5.6; they lack
adequate clash resolution handling.
Patch was originally written by Pablo Neira Ayuso.

Add for_each_tracepoint_in_module() function to iterate tracepoints in
a module. This API is needed for handling tracepoints in a loading
module from tracepoint_module_notifier callback function.
This also update for_each_module_tracepoint() to pass the module to
callback function so that it can find module easily.

On PVH dom0, when passthrough a device to domU, QEMU and xl tools
want to use gsi number to do pirq mapping, see QEMU code
xen_pt_realize->xc_physdev_map_pirq, and xl code
pci_add_dm_done->xc_physdev_map_pirq, but in current codes, the gsi
number is got from file /sys/bus/pci/devices/<sbdf>/irq, that is
wrong, because irq is not equal with gsi, they are in different
spaces, so pirq mapping fails.
And in current linux codes, there is no method to get gsi
for userspace.
For above purpose, record gsi of pcistub devices when init
pcistub and add a new syscall into privcmd to let userspace
can get gsi when they have a need.

In PVH dom0, the gsis don't get registered, but the gsi of
a passthrough device must be configured for it to be able to be
mapped into a domU.
When assigning a device to passthrough, proactively setup the gsi
of the device during that process.

When device on dom0 side has been reset, the vpci on Xen side
won't get notification, so that the cached state in vpci is
all out of date with the real device state.
To solve that problem, add a new function to clear all vpci
device state when device is reset on dom0 side.
And call that function in pcistub_init_device. Because when
using "pci-assignable-add" to assign a passthrough device in
Xen, it will reset passthrough device and the vpci state will
out of date, and then device will fail to restore bar state.

Pull more io_uring updates from Jens Axboe:
"Mostly just a set of fixes in here, or little changes that didn't get
included in the initial pull request. This contains:
- Move the SQPOLL napi polling outside the submission lock (Olivier)
- Rename of the "copy buffers" API that got added in the 6.12 merge
window. There's really no copying going on, it's just referencing
the buffers. After a bit of consideration, decided that it was
better to simply rename this to avoid potential confusion (me)
- Shrink struct io_mapped_ubuf from 48 to 32 bytes, by changing it to
start + len tracking rather than having start / end in there, and
by removing the caching of folio_mask when we can just calculate it
from folio_shift when we need it (me)
- Fixes for the SQPOLL affinity checking (me, Felix)
- Fix for how cqring waiting checks for the presence of task_work.
Just check it directly rather than check for a specific
notification mechanism (me)
- Tweak to how request linking is represented in tracing (me)
- Fix a syzbot report that deliberately sets up a huge list of
overflow entries, and then hits rcu stalls when flushing this list.
Just check for the need to preempt, and drop/reacquire locks in the
loop. There's no state maintained over the loop itself, and each
entry is yanked from head-of-list (me)"

The largest infoframe we create is the DRM (Dynamic Range Mastering)
infoframe which is 26 bytes + a 4 byte header, for a total of 30
bytes.
With HDMI_MAX_INFOFRAME_SIZE set to 29 bytes, as it is now, we
allocate too little space to pack a DRM infoframe in
write_device_infoframe(), leading to an ENOSPC return from
hdmi_infoframe_pack(), and never calling the connector's
write_infoframe() vfunc.
Instead of having HDMI_MAX_INFOFRAME_SIZE defined in two places,
replace HDMI_MAX_INFOFRAME_SIZE with HDMI_INFOFRAME_SIZE(MAX) and make
MAX 27 bytes - which is defined by the HDMI specification to be the
largest infoframe payload.

Fixes a race condition reported here: https://github.com/AsahiLinux/linux/issues/309#issuecomment-2238968609
The whole premise of lockless access to a single-producer-single-
consumer queue is that there is just a single producer and single
consumer. That means we can't call drm_sched_can_queue() (which is
about queueing more work to the hw, not to the spsc queue) from
anywhere other than the consumer (wq).
This call in the producer is just an optimization to avoid scheduling
the consuming worker if it cannot yet queue more work to the hw. It
is safe to drop this optimization to avoid the race condition.

Pull clk updates from Stephen Boyd:
"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.
Core:
- KUnit tests for clk registration and fixed rate basic clk type
- A couple more devm helpers, one consumer and one provider
- Support for assigned-clock-rates-u64
New Drivers:
- Camera, display and GPU clocks on Qualcomm SM4450
- Camera clocks on Qualcomm SM8150
- Rockchip rk3576 clks
- Microchip SAM9X7 clks
- Renesas RZ/V2H(P) (R9A09G057) clks
Updates:
- Mark a bunch of struct freq_tbl const to reduce .data usage
- Add Qualcomm MSM8226 A7PLL and Regera PLL support
- Fix the Qualcomm Lucid 5LPE PLL configuration sequence to not reuse
Trion, as they do differ

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.
Improvements:
- several patches improving the runtime power management handling of
the Renesas I2C (riic) driver
- use a more descriptive adapter name in the Intel i801 driver to
show the presence of the IDF feature
- kill pending transactions when irq's can't complete their handling
in the Intel Denverton (ismt) driver, triggering a timeout
New Feature:
- support fast mode plus in the Renesas I2C (riic) driver
New support:
- Added support for:
- Renesas R9A08G045
- Rockchip RK3576
- KEBA I2C
- Theobroma Systems Mule Multiplexer.
- new i2c-keba.c driver
- new driver for The Mule i2c multiplexer
Core I2C framework:
- move runtime PM functions in order to allow them to be accessed
during device add
Devicetree:
- nVidia and Qualcomm binding improvements
- get rid of redundant "multi-master" property in the aspeed binding
- convert i2c-sprd binding to YAML
AT24 updates:
- document a new model from giantec in DT bindings"

Pull firewire updates from Takashi Sakamoto:
"In the FireWire subsystem, tasklets have been used as the bottom half
of 1394 OHCi hardIRQ. In recent kernel updates, BH workqueues have
become available, and some developers have proposed replacing the
tasklet with a BH workqueue.
As a first step towards dropping tasklet use, the 1394 OHCI
isochronous context can use regular workqueues. In this 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 normal workqueues are suitable,
through BH workqueues are not.
The replacement with a 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.
Summary:
- Replace tasklet with workqueue for isochronous context
- Replace IDR with XArray
- Utilize guard macro where possible
- Print deprecation warning when enabling debug parameter of
firewire-ohci module
- Switch to nonatomic PCM operation"

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().

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. The server expects this protocol to use
the same transport as NFS and NFSACL for its RPCs. 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.
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.
The RPC program number for the NFS_LOCALIO_PROGRAM is 400122 (as assigned
by IANA, see https://www.iana.org/assignments/rpc-program-numbers/ ):

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.
CONFIG_NFS_LOCALIO enables NFS server support for LOCALIO.

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).

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).

A service created with svc_create_pooled() can be given a linked list of
programs and all of these will be served.
Using a linked list makes it cumbersome when there are several programs
that can be optionally selected with CONFIG settings.
After this patch is applied, API consumers must use only
svc_create_pooled() when creating an RPC service that listens for more
than one RPC program.

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.
