Use dev_get_drvdata(dev->parent) instead of dev_get_platdata(dev)
to correctly obtain acp_chip_info members in the acp I2S driver.
Previously, some members were not updated properly due to incorrect
data access, which could potentially lead to null pointer
dereferences.
This issue was missed in the earlier commit
("ASoC: amd: acp: Fix NULL pointer deref in acp_i2s_set_tdm_slot"),
which only addressed set_tdm_slot(). This change ensures that all
relevant functions correctly retrieve acp_chip_info, preventing
further null pointer dereference issues.

Xiumei reported a regression in IPsec offload tests over xfrmi, where
the traffic for IPv6 over IPv4 tunnels is processed in SW instead of
going through crypto offload, after commit
cc18f482e8 ("xfrm: provide common xdo_dev_offload_ok callback
implementation").
Commit cc18f482e8 added a generic version of existing checks
attempting to prevent packets with IPv4 options or IPv6 extension
headers from being sent to HW that doesn't support offloading such
packets. The check mistakenly uses x->props.family (the outer family)
to determine the inner packet's family and verify if
options/extensions are present.
In the case of IPv6 over IPv4, the check compares some of the traffic
class bits to the expected no-options ihl value (5). The original
check was introduced in commit 2ac9cfe782 ("net/mlx5e: IPSec, Add
Innova IPSec offload TX data path"), and then duplicated in the other
drivers. Before commit cc18f482e8, the loose check (ihl > 5) passed
because those traffic class bits were not set to a value that
triggered the no-offload codepath. Packets with options/extension
headers that should have been handled in SW went through the offload
path, and were likely dropped by the NIC or incorrectly
processed. Since commit cc18f482e8, the check is now strict (ihl !=
5), and in a basic setup (no traffic class configured), all packets go
through the no-offload codepath.
The commits that introduced the incorrect family checks in each driver
are:
2ac9cfe782 ("net/mlx5e: IPSec, Add Innova IPSec offload TX data path")
8362ea16f6 ("crypto: chcr - ESN for Inline IPSec Tx")

Argument 'p' of enabled_monitors_next() is not a pointer to struct

This is no longer true since commit 24cbfe18d5 ("rv: Merge struct

When sorting the block group list for reclaim we are using a block group's
used bytes counter without taking the block group's spinlock, so we can
race with a concurrent task updating it (at btrfs_update_block_group()),
which makes tools like KCSAN unhappy and report a race.
Since the sorting is not strictly needed from a functional perspective
and such races should rarely cause any ordering changes (only load/store
tearing could cause them), not to mention that after the sorting the
ordering may no longer be accurate due to concurrent allocations and
deallocations of extents in a block group, annotate the accesses to the
used counter with data_race() to silence KCSAN and similar tools.

We should not use more sges for ib_post_send() than we told the rdma
device in rdma_create_qp()!
Otherwise ib_post_send() will return -EINVAL, so we disconnect the
connection. Or with the current siw.ko we'll get 0 from ib_post_send(),
but will never ever get a completion for the request. I've already sent a
fix for siw.ko...
So we need to make sure smb_direct_writev() limits the number of vectors
we pass to individual smb_direct_post_send_data() calls, so that we
don't go over the queue pair limits.
Commit 621433b7e2 ("ksmbd: smbd: relax the count of sges required")
was very strange and I guess only needed because
SMB_DIRECT_MAX_SEND_SGES was 8 at that time. It basically removed the
check that the rdma device is able to handle the number of sges we try
to use.
While the real problem was added by commit ddbdc861e3 ("ksmbd: smbd:
introduce read/write credits for RDMA read/write") as it used the
minumun of device->attrs.max_send_sge and device->attrs.max_sge_rd, with
the problem that device->attrs.max_sge_rd is always 1 for iWarp. And
that limitation should only apply to RDMA Read operations. For now we
keep that limitation for RDMA Write operations too, fixing that is a
task for another day as it's not really required a bug fix.
Commit 2b4eeeaa90 ("ksmbd: decrease the number of SMB3 smbdirect
server SGEs") lowered SMB_DIRECT_MAX_SEND_SGES to 6, which is also used
by our client code. And that client code enforces
device->attrs.max_send_sge >= 6 since commit d2e81f92e5 ("Decrease the
number of SMB3 smbdirect client SGEs") and (briefly looking) only the
i40w driver provides only 3, see I40IW_MAX_WQ_FRAGMENT_COUNT. But
currently we'd require 4 anyway, so that would not work anyway, but now
it fails early.

net: dst_metadata: fix DF flag extraction on tunnel rx
Two patches here, first fixes the issue where tunnel core doesn't
actually extract DF bit from the outer IP header, even though both
OVS and TC flower allow matching on it. More details in the commit
message.
The second is a selftest for openvswitch that reproduces the issue,
but also just adds some basic coverage for the tunnel metadata

This test ensures that upon receiving decapsulated packets from a
tunnel interface in openvswitch, the tunnel metadata fields are
properly populated. This partially covers interoperability of the
kernel tunnel ports and openvswitch tunnels (LWT) and parsing and
formatting of the tunnel metadata fields of the openvswitch netlink
uAPI. Doing so, this test also ensures that fields and flags are
properly extracted during decapsulation by the tunnel core code,
serving as a regression test for the previously fixed issue with the
DF bit not being extracted from the outer IP header.
The ovs-dpctl.py script already supports all that is necessary for
the tunnel ports for this test, so we only need to adjust the
ovs_add_if() function to pass the '-t' port type argument in order
to be able to create tunnel ports in the openvswitch datapath.

Both OVS and TC flower allow extracting and matching on the DF bit of
the outer IP header via OVS_TUNNEL_KEY_ATTR_DONT_FRAGMENT in the
OVS_KEY_ATTR_TUNNEL and TCA_FLOWER_KEY_FLAGS_TUNNEL_DONT_FRAGMENT in
the TCA_FLOWER_KEY_ENC_FLAGS respectively. Flow dissector extracts
this information as FLOW_DIS_F_TUNNEL_DONT_FRAGMENT from the tunnel
info key.
However, the IP_TUNNEL_DONT_FRAGMENT_BIT in the tunnel key is never
actually set, because the tunneling code doesn't actually extract it
from the IP header. OAM and CRIT_OPT are extracted by the tunnel
implementation code, same code also sets the KEY flag, if present.
UDP tunnel core takes care of setting the CSUM flag if the checksum
is present in the UDP header, but the DONT_FRAGMENT is not handled at
any layer.
Fix that by checking the bit and setting the corresponding flag while
populating the tunnel info in the IP layer where it belongs.
Not using __assign_bit as we don't really need to clear the bit in a
just initialized field. It also doesn't seem like using __assign_bit
will make the code look better.
Clearly, users didn't rely on this functionality for anything very
important until now. The reason why this doesn't break OVS logic is
that it only matches on what kernel previously parsed out and if kernel
consistently reports this bit as zero, OVS will only match on it to be
zero, which sort of works. But it is still a bug that the uAPI reports
and allows matching on the field that is not actually checked in the
packet. And this is causing misleading -df reporting in OVS datapath
flows, while the tunnel traffic actually has the bit set in most cases.
This may also cause issues if a hardware properly implements support
for tunnel flag matching as it will disagree with the implementation
in a software path of TC flower.

Fix the following Smatch static checker warning:
net/rxrpc/rxgk_app.c:65 rxgk_yfs_decode_ticket()
warn: untrusted unsigned subtract. 'ticket_len - 10 * 4'
by prechecking the length of what we're trying to extract in two places in
the token and decoding for a response packet.
Also use sizeof() on the struct we're extracting rather specifying the size
numerically to be consistent with the other related statements.

rxgk_verify_packet_integrity() may get more errors than just -EPROTO from
rxgk_verify_mic_skb(). Pretty much anything other than -ENOMEM constitutes
an unrecoverable error. In the case of -ENOMEM, we can just drop the
packet and wait for a retransmission.
Similar happens with rxgk_decrypt_skb() and its callers.
Fix rxgk_decrypt_skb() or rxgk_verify_mic_skb() to return a greater variety
of abort codes and fix their callers to abort the connection on any error
apart from -ENOMEM.
Also preclear the variables used to hold the abort code returned from
rxgk_decrypt_skb() or rxgk_verify_mic_skb() to eliminate uninitialised
variable warnings.

A NULL pointer dereference can occur in tcp_ao_finish_connect() during a
connect() system call on a socket with a TCP-AO key added and TCP_REPAIR
enabled.
The function is called with skb being NULL and attempts to dereference it
on tcp_hdr(skb)->seq without a prior skb validation.
Fix this by checking if skb is NULL before dereferencing it.
The commentary is taken from bpf_skops_established(), which is also called
in the same flow. Unlike the function being patched,
bpf_skops_established() validates the skb before dereferencing it.

When accessing one of the files under /sys/fs/nilfs2/features when
CONFIG_CFI_CLANG is enabled, there is a CFI violation:
CFI failure at kobj_attr_show+0x59/0x80 (target: nilfs_feature_revision_show+0x0/0x30; expected type: 0xfc392c4d)
...
Call Trace:
<TASK>

kernfs_seq_show+0x104/0x15b
seq_read_iter+0x580/0xe2b
...
When the kobject of the kset for /sys/fs/nilfs2 is initialized, its ktype
is set to kset_ktype, which has a ->sysfs_ops of kobj_sysfs_ops. When
nilfs_feature_attr_group is added to that kobject via
sysfs_create_group(), the kernfs_ops of each files is sysfs_file_kfops_rw,
which will call sysfs_kf_seq_show() when ->seq_show() is called.
sysfs_kf_seq_show() in turn calls kobj_attr_show() through
->sysfs_ops->show(). kobj_attr_show() casts the provided attribute out to
a 'struct kobj_attribute' via container_of() and calls ->show(), resulting
in the CFI violation since neither nilfs_feature_revision_show() nor
nilfs_feature_README_show() match the prototype of ->show() in 'struct
kobj_attribute'.
Resolve the CFI violation by adjusting the second parameter in
nilfs_feature_{revision,README}_show() from 'struct attribute' to 'struct
kobj_attribute' to match the expected prototype.

Patch series "samples/damon: fix boot time enable handling fixup merge
mistakes".
First three patches of the patch series "mm/damon: fix misc bugs in DAMON
modules" [1] were trying to fix boot time DAMON sample modules enabling
issues. The issues are the modules can crash if those are enabled before
DAMON is enabled, like using boot time parameter options. The three
patches were fixing the issues by avoiding starting DAMON before the
module initialization phase.
However, probably by a mistake during a merge, only half of the change is
merged, and the part for avoiding the starting of DAMON before the module
initialized is missed. So the problem is not solved and thus the modules
can still crash if enabled before DAMON is initialized. Fix those by
applying the unmerged parts again.
Note that the broken commits are merged into 6.17-rc1, but also backported
to relevant stable kernels. So this series also needs to be merged into
the stable kernels. Hence Cc-ing stable@.
This patch (of 3):
Commit 0ed1165c37 ("samples/damon/wsse: fix boot time enable handling")
is somehow incompletely applying the origin patch [2]. It is missing the
part that avoids starting DAMON before module initialization. Probably a
mistake during a merge has happened. Fix it by applying the missed part
again.
