no_llseek had been defined to NULL two years ago, in commit 868941b144
("fs: remove no_llseek")
To quote that commit,
At -rc1 we'll need do a mechanical removal of no_llseek -
git grep -l -w no_llseek | grep -v porting.rst | while read i; do
sed -i '/\<no_llseek\>/d' $i
done
would do it.
Unfortunately, that hadn't been done. Linus, could you do that now, so
that we could finally put that thing to rest? All instances are of the
form
.llseek = no_llseek,
so it's obviously safe.

The logging was questionable to begin with, but it seems to actively
deadlock on the task lock.
"On second thought, let's not log core dump failures. 'Tis a silly place"
because if you can't tell your core dump is truncated, maybe you should
just fix your debugger instead of adding bugs to the kernel.

Here is the "big" set of char/misc and other driver subsystem changes
for 6.12-rc1. Sorry for the delay, conference travel for the past two
weeks has this and my other pull requests showing up real late
in the cycle.
Lots of changes in here, primarily dominated by the usual IIO driver
updates and additions, but there are also small driver subsystem updates
all over the place. Included in here are:
- lots and lots of new IIO drivers and updates to existing ones
- interconnect subsystem updates and new drivers
- nvmem subsystem updates and new drivers
- mhi driver updates
- power supply subsystem updates
- kobj_type const work for many different small subsystems
- comedi driver fix
- coresight subsystem and driver updates
- fpga subsystem improvements
- slimbus fixups
- binder new feature addition for "frozen" notifications
- lots and lots of other small driver updates and cleanups
All of these have been in linux-next for a long time with no reported
problems.

Here is the big set of staging driver cleanups and removals for
6.12-rc1.
Nothing exciting here, just slow, constant, forward progress in removing
code and cleaning up some old drivers, along with removing one of them
that was not being used anymore at all. In discussions with some
developers this past week, even more deletions will be happening for the
next major merge window, as we seems to have code here that obviously no
one is using anymore.
Along with the normal cleanups is the good vme_user code forward
progress, the one major bright spot in the staging subsystem for code
that people rely on, and is getting good development behind it.
Hopefully it can graduate out of staging "soon".
All of these changes have been in linux-next for a long time with no

- 8250_platform driver cleanups
- samsung serial driver fixes and updates
- qcom-geni serial driver fixes from Johan for the bizarre UART engine
that that chip seems to have. Hopefully it's in a better state now,
but hardware designers still seem to come up with more ways to make
broken UARTS 40+ years after this all should have finished.
- sc16is7xx driver updates

====================
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.

Within the same patch series of the commit above, the commit 046322f1e1
("ARM: ep93xx: DT for the Cirrus ep93xx SoC platforms") then removes the
config EP93XX_SOC_COMMON. With that the reference to this config is

The netfilter race happens when two packets with the same tuple are DNATed
and enqueued with nfqueue in the postrouting hook.
Once one of the packet is reinjected it may be DNATed again to a different
destination, but the conntrack entry remains the same and the return packet
was dropped.
Based on earlier patch from Antonio Ojea.

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 368982cd7d ("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 6a757c07e5 ("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 ee04805ff5 ("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.

Only provide ctnetlink_label_size when it is used,
which is when CONFIG_NF_CONNTRACK_EVENTS is configured.
Flagged by clang-18 W=1 builds as:
.../nf_conntrack_netlink.c:385:19: warning: unused function 'ctnetlink_label_size' [-Wunused-function]
385 | static inline int ctnetlink_label_size(const struct nf_conn *ct)
| ^~~~~~~~~~~~~~~~~~~~
The condition on CONFIG_NF_CONNTRACK_LABELS being removed by
this patch guards compilation of non-trivial implementations
of ctnetlink_dump_labels() and ctnetlink_label_size().
However, this is not necessary as each of these functions
will always return 0 if CONFIG_NF_CONNTRACK_LABELS is not defined
as each function starts with the equivalent of:
struct nf_conn_labels *labels = nf_ct_labels_find(ct);
if (!labels)
return 0;
And nf_ct_labels_find always returns NULL if CONFIG_NF_CONNTRACK_LABELS
is not enabled. So I believe that the compiler optimises the code away
in such cases anyway.
Found by inspection.
Compile tested only.
Originally splitted in two patches, Pablo Neira Ayuso collapsed them and
added Fixes: tag.

The TPROXY functionality is widely used, however, there are only mptcp
selftests covering this feature.
The selftests represent the most common scenarios and can also be used
as selfdocumentation of the feature.
UDP and TCP testcases are split in different files because of the
different nature of the protocols, specially due to the challenges that
present to reliable test UDP due to the connectionless nature of the
protocol. UDP only covers the scenarios involving the prerouting hook.
The UDP tests are signfinicantly slower than the TCP ones, hence they
use a larger timeout, it takes 20 seconds to run the full UDP suite
on a 48 vCPU Intel(R) Xeon(R) CPU @2.60GHz.

Add test program that is sending UDP packets in both directions
and check that packets arrive without source port modification.

Given existing entry:
ORIGIN: a:b -> c:d
REPLY: c:d -> a:b
And colliding entry:
ORIGIN: c:d -> a:b
REPLY: a:b -> c:d
The colliding ct (and the associated skb) get dropped on insert.
Permit this by checking if the colliding entry matches the reply
direction.
Happens when both ends send packets at same time, both requests are picked
up as NEW, rather than NEW for the 'first' and 'ESTABLISHED' for the
second packet.
This is an esoteric condition, as ruleset must permit NEW connections
in either direction and both peers must already have a bidirectional
traffic flow at the time conntrack gets enabled.
Allow the 'reverse' skb to pass and assign the existing (clashing)
entry.
While at it, also drop the extra 'dying' check, this is already
tested earlier by the calling function.

A conntrack entry can be inserted to the connection tracking table if there
is no existing entry with an identical tuple in either direction.
Example:
INITIATOR -> NAT/PAT -> RESPONDER
Initiator passes through NAT/PAT ("us") and SNAT is done (saddr rewrite).
Then, later, NAT/PAT machine itself also wants to connect to RESPONDER.
This will not work if the SNAT done earlier has same IP:PORT source pair.
Conntrack table has:
ORIGINAL: $IP_INITATOR:$SPORT -> $IP_RESPONDER:$DPORT
REPLY: $IP_RESPONDER:$DPORT -> $IP_NAT:$SPORT
and new locally originating connection wants:
ORIGINAL: $IP_NAT:$SPORT -> $IP_RESPONDER:$DPORT
REPLY: $IP_RESPONDER:$DPORT -> $IP_NAT:$SPORT
This is handled by the NAT engine which will do a source port reallocation
for the locally originating connection that is colliding with an existing
tuple by attempting a source port rewrite.
This is done even if this new connection attempt did not go through a
masquerade/snat rule.
There is a rare race condition with connection-less protocols like UDP,
where we do the port reallocation even though its not needed.
This happens when new packets from the same, pre-existing flow are received
in both directions at the exact same time on different CPUs after the
conntrack table was flushed (or conntrack becomes active for first time).
With strict ordering/single cpu, the first packet creates new ct entry and
second packet is resolved as established reply packet.
With parallel processing, both packets are picked up as new and both get
their own ct entry.
In this case, the 'reply' packet (picked up as ORIGINAL) can be mangled by
NAT engine because a port collision is detected.
This change isn't enough to prevent a packet drop later during
nf_conntrack_confirm(), the existing clash resolution strategy will not
detect such reverse clash case. This is resolved by a followup patch.

Commit 5fabb01207 ("net: stmmac: Add initial XDP support") sets
PP_FLAG_DMA_SYNC_DEV flag for page_pool unconditionally,
page_pool_recycle_direct() will call page_pool_dma_sync_for_device()
on every page even the page is not going to be reused by XDP program.
When XDP is not enabled, the page which holds the received buffer
will be recycled once the buffer is copied into new SKB by
skb_copy_to_linear_data(), then the MAC core will never reuse this
page any longer. Always setting PP_FLAG_DMA_SYNC_DEV wastes CPU cycles
on unnecessary calling of page_pool_dma_sync_for_device().
After this patch, up to 9% noticeable performance improvement was observed
on certain platforms.

Currently, the virtio-net driver will perform a pre-dma-mapping for
small or mergeable RX buffer. But for small packets, a mismatched address
without VIRTNET_RX_PAD and xdp_headroom is used for unmapping.
That will result in unsynchronized buffers when SWIOTLB is enabled, for
example, when running as a TDX guest.
This patch unifies the address passed to the virtio core as the address of
the virtnet header and fixes the mismatched buffer address.
Changes from v2: unify the buf that passed to the virtio core in small
and merge mode.
Changes from v1: Use ctx to get xdp_headroom.

Currently the Rust support is gated on not having MODVERSIONS enabled,
and as a result an "allmodconfig" build will disable Rust build tests.
While MODVERSIONS configurations are worth build testing, the feature is
not actually meaningful unless you run the result, and I'd rather get
build coverage of Rust than MODVERSIONS. So let's disable MODVERSIONS

objtool-warning-free, so enable it to run for all Rust object files.
- KASAN (no 'SW_TAGS'), KCFI and shadow call sanitizer support.
- Support 'RUSTC_VERSION', including re-config and re-build on change.
- Split helpers file into several files in a folder, to avoid conflicts
in it. Eventually those files will be moved to the right places with
the new build system. In addition, remove the need to manually export
the symbols defined there, reusing existing machinery for that.
- Relax restriction on configurations with Rust + GCC plugins to just
the RANDSTRUCT plugin.
'kernel' crate:
- New 'list' module: doubly-linked linked list for use with reference
counted values, which is heavily used by the upcoming Rust Binder.
This includes 'ListArc' (a wrapper around 'Arc' that is guaranteed
unique for the given ID), 'AtomicTracker' (tracks whether a 'ListArc'
exists using an atomic), 'ListLinks' (the prev/next pointers for an
item in a linked list), 'List' (the linked list itself), 'Iter' (an
iterator over a 'List'), 'Cursor' (a cursor into a 'List' that allows
to remove elements), 'ListArcField' (a field exclusively owned by a
'ListArc'), as well as support for heterogeneous lists.
- New 'rbtree' module: red-black tree abstractions used by the upcoming
Rust Binder. This includes 'RBTree' (the red-black tree itself),
'RBTreeNode' (a node), 'RBTreeNodeReservation' (a memory reservation
for a node), 'Iter' and 'IterMut' (immutable and mutable iterators),
'Cursor' (bidirectional cursor that allows to remove elements), as
well as an entry API similar to the Rust standard library one.
- 'init' module: add 'write_[pin_]init' methods and the 'InPlaceWrite'
trait. Add the 'assert_pinned!' macro.
- 'sync' module: implement the 'InPlaceInit' trait for 'Arc' by
introducing an associated type in the trait.
- 'alloc' module: add 'drop_contents' method to 'BoxExt'.
- 'types' module: implement the 'ForeignOwnable' trait for
'Pin<Box<T>>' and improve the trait's documentation. In addition,
add the 'into_raw' method to the 'ARef' type.
- 'error' module: in preparation for the upcoming Rust support for
32-bit architectures, like arm, locally allow Clippy lint for those.
Documentation:
- https://rust.docs.kernel.org has been announced, so link to it.
- Enable rustdoc's "jump to definition" feature, making its output a
bit closer to the experience in a cross-referencer.
- Debian Testing now also provides recent Rust releases (outside of
the freeze period), so add it to the list.

Support raw tracepoint events on future loaded (unloaded) modules.
This allows user to create raw tracepoint events which can be used from
module's __init functions.
Note: since the kernel does not have any information about the tracepoints
in the unloaded modules, fprobe events can not check whether the tracepoint
exists nor extend the BTF based arguments.
