Pull spi fixes from Mark Brown:
"A few small fixes for v6.9,
The core fix is for issues with reuse of a spi_message in the case
where we've got queued messages (a relatively rare occurrence with
modern code so it wasn't noticed in testing).
We also avoid an issue with the Kunpeng driver by simply removing the
debug interface that could trigger it, and address issues with
confusing and corrupted output when printing the IP version of the AXI
SPI engine"

Pull firewire fixes from Takashi Sakamoto:
"Two driver fixes:
- The firewire-ohci driver for 1394 OHCI hardware does not fill time
stamp for response packet when handling asynchronous transaction to
local destination. This brings an inconvenience that the response

remote. It is fixed by fulfilling the time stamp with hardware
time. The fix should be applied to Linux kernel v6.5 or later as
well.

long-standing issue about the behaviour when user space application

====================
net: gro: add flush/flush_id checks and fix wrong offset in udp
This series fixes a bug in the complete phase of UDP in GRO, in which
socket lookup fails due to using network_header when parsing encapsulated
packets. The fix is to add network_offset and inner_network_offset to
napi_gro_cb and use these offsets for socket lookup.
In addition p->flush/flush_id should be checked in all UDP flows. The
same logic from tcp_gro_receive is applied for all flows in
udp_gro_receive_segment. This prevents packets with mismatching network
headers (flush/flush_id turned on) from merging in UDP GRO.
The original series includes a change to vxlan test which adds the local
parameter to prevent similar future bugs. I plan to submit it separately to
net-next.
This series is part of a previously submitted series to net-next:
https://lore.kernel.org/all/[email protected]/

- Store network offsets, and use them only in udp_gro_complete flows
- Correct commit hash used in Fixes tag
- v3:

v2 -> v3:
- Add network_offsets and fix udp bug in a single commit to make backporting easier
- Write to inner_network_offset in {inet,ipv6}_gro_receive
- Use network_offsets union in tcp[46]_gro_complete as well
- v2:
https://lore.kernel.org/netdev/[email protected]/

- Use network_offsets instead of p_poff param as suggested by Willem
- Check flush before postpull, and for all UDP GRO flows

GRO-GSO path is supposed to be transparent and as such L3 flush checks are
relevant to all UDP flows merging in GRO. This patch uses the same logic
and code from tcp_gro_receive, terminating merge if flush is non zero.

{inner_}network_offset to napi_gro_cb
Commits a602456 ("udp: Add GRO functions to UDP socket") and 57c67ff ("udp:
additional GRO support") introduce incorrect usage of {ip,ipv6}_hdr in the
complete phase of gro. The functions always return skb->network_header,
which in the case of encapsulated packets at the gro complete phase, is
always set to the innermost L3 of the packet. That means that calling
{ip,ipv6}_hdr for skbs which completed the GRO receive phase (both in
gro_list and *_gro_complete) when parsing an encapsulated packet's _outer_
L3/L4 may return an unexpected value.
This incorrect usage leads to a bug in GRO's UDP socket lookup.
udp{4,6}_lib_lookup_skb functions use ip_hdr/ipv6_hdr respectively. These
*_hdr functions return network_header which will point to the innermost L3,
resulting in the wrong offset being used in __udp{4,6}_lib_lookup with
encapsulated packets.
This patch adds network_offset and inner_network_offset to napi_gro_cb, and
makes sure both are set correctly.
To fix the issue, network_offsets union is used inside napi_gro_cb, in
which both the outer and the inner network offsets are saved.
Reproduction example:
Endpoint configuration example (fou + local address bind)
# ip fou add port 6666 ipproto 4
# ip link add name tun1 type ipip remote 2.2.2.1 local 2.2.2.2 encap fou encap-dport 5555 encap-sport 6666 mode ipip
# ip link set tun1 up
# ip a add 1.1.1.2/24 dev tun1

KMSAN reported uninit-value access in __ip_make_skb() [1]. __ip_make_skb()
tests HDRINCL to know if the skb has icmphdr. However, HDRINCL can cause a
race condition. If calling setsockopt(2) with IP_HDRINCL changes HDRINCL
while __ip_make_skb() is running, the function will access icmphdr in the
skb even if it is not included. This causes the issue reported by KMSAN.
Check FLOWI_FLAG_KNOWN_NH on fl4->flowi4_flags instead of testing HDRINCL
on the socket.
Also, fl4->fl4_icmp_type and fl4->fl4_icmp_code are not initialized. These
are union in struct flowi4 and are implicitly initialized by
flowi4_init_output(), but we should not rely on specific union layout.
Initialize these explicitly in raw_sendmsg().

When the hsuid attribute is set for the first time on an IQD Layer3
device while the corresponding network interface is already UP,
the kernel will try to execute a napi function pointer that is NULL.

Analysis:
There is one napi structure per out_q: card->qdio.out_qs[i].napi
The napi.poll functions are set during qeth_open().
Since
commit 1cfef80d4c2b ("s390/qeth: Don't call dev_close/dev_open (DOWN/UP)")
qeth_set_offline()/qeth_set_online() no longer call dev_close()/
dev_open(). So if qeth_free_qdio_queues() cleared
card->qdio.out_qs[i].napi.poll while the network interface was UP and the
card was offline, they are not set again.
Reproduction:
chzdev -e $devno layer2=0
ip link set dev $network_interface up
echo 0 > /sys/bus/ccwgroup/devices/0.0.$devno/online
echo foo > /sys/bus/ccwgroup/devices/0.0.$devno/hsuid
echo 1 > /sys/bus/ccwgroup/devices/0.0.$devno/online
-> Crash (can be enforced e.g. by af_iucv connect(), ip link down/up, ...)
Note that a Completion Queue (CQ) is only enabled or disabled, when hsuid
is set for the first time or when it is removed.
Workarounds:
- Set hsuid before setting the device online for the first time
or
- Use chzdev -d $devno; chzdev $devno hsuid=xxx; chzdev -e $devno;
to set hsuid on an existing device. (this will remove and recreate the
network interface)
Fix:
There is no need to free the output queues when a completion queue is
added or removed.
card->qdio.state now indicates whether the inbound buffer pool and the
outbound queues are allocated.
card->qdio.c_q indicates whether a CQ is allocated.

Ensure the inner IP header is part of skb's linear data before reading
its ECN bits. Otherwise we might read garbage.
One symptom is the system erroneously logging errors like
"vxlan: non-ECT from xxx.xxx.xxx.xxx with TOS=xxxx".
Similar bugs have been fixed in geneve, ip_tunnel and ip6_tunnel (see
commit 1ca1ba465e55 ("geneve: make sure to pull inner header in
geneve_rx()") for example). So let's reuse the same code structure for
consistency. Maybe we'll can add a common helper in the future.

The find connection logic of Transarc's Rx was modified in the mid-1990s
to support multi-homed servers which might send a response packet from
an address other than the destination address in the received packet.
The rules for accepting a packet by an Rx initiator (RX_CLIENT_CONNECTION)
were altered to permit acceptance of a packet from any address provided
that the port number was unchanged and all of the connection identifiers
matched (Epoch, CID, SecurityClass, ...).
This change applies the same rules to the Linux implementation which makes
it consistent with IBM AFS 3.6, Arla, OpenAFS and AuriStorFS.

cleanups from Matti which fix issues found with client drivers due to
the API being confusing.
The two fixes for the stubs provide more constructive behaviour with
!REGULATOR configurations, issues were noticed with some hwmon drivers
which would otherwise have needed confusing bodges in the users.
The irq_helpers fix to duplicate the provided name for the interrupt
controller was found because a driver got this wrong and it's again a

With commit ed6776c96c60 ("s390/crypto: remove retry
loop with sleep from PAES pkey invocation") the retry
loop to retry derivation of a protected key from a
secure key has been removed. This was based on the
assumption that theses retries are not needed any
more as proper retries are done in the zcrypt layer.
However, tests have revealed that there exist some
cases with master key change in the HSM and immediately
(< 1 second) attempt to derive a protected key from a
secure key with exact this HSM may eventually fail.
The low level functions in zcrypt_ccamisc.c and
zcrypt_ep11misc.c detect and report this temporary
failure and report it to the caller as -EBUSY. The
re-established retry loop in the paes implementation
catches exactly this -EBUSY and eventually may run
some retries.

An EP11 reply cprb contains a field ret_code which may
hold an error code different than the error code stored
in the payload of the cprb. As of now all the EP11 misc
functions do not evaluate this field but focus on the
error code in the payload.
Before checking the payload error, first the cprb error
field should be evaluated which is introduced with this
patch.
If the return code value 0x000c0003 is seen, this
indicates a busy situation which is reflected by
-EBUSY in the zcrpyt_ep11misc.c low level function.
A higher level caller should consider to retry after
waiting a dedicated duration (say 1 second).

When fallback to TCP happens early on a client socket, snd_nxt
is not yet initialized and any incoming ack will copy such value
into snd_una. If the mptcp worker (dumbly) tries mptcp-level
re-injection after such ack, that would unconditionally trigger a send
buffer cleanup using 'bad' snd_una values.
We could easily disable re-injection for fallback sockets, but such
dumb behavior already helped catching a few subtle issues and a very
low to zero impact in practice.
Instead address the issue always initializing snd_nxt (and write_seq,
for consistency) at connect time.

This is a partial revert of commit 6dbdd4de0362 ("e1000e: Workaround
for sporadic MDI error on Meteor Lake systems"). The referenced commit
used usleep_range inside the PHY access routines, which are sometimes
called from an atomic context. This can lead to a kernel panic in some
scenarios, such as cable disconnection and reconnection on vPro systems.
Solve this by changing the usleep_range calls back to udelay.

The selftest for the driver sends a dummy packet and checks if the
packet will be received properly as it should be. The regular TX path
and the selftest can use the same network queue so locking is required
and was missing in the selftest path. This was addressed in the commit
cited below.
Unfortunately locking the TX queue requires BH to be disabled which is
not the case in selftest path which is invoked in process context.
Lockdep should be complaining about this.
Use __netif_tx_lock_bh() for TX queue locking.

is supposed to be an order-based alignment value, but zero is
not a valid order-based alignment value, and '~(data_align - 1)'
doesn't result in a valid mask-based alignment value for
__page_frag_alloc_align().
Fix it by passing a valid order-based alignment value in
none_alloc_txbuf() and rxkad_alloc_txbuf().
Also use page_frag_alloc_align() expecting an order-based
alignment value in rxrpc_alloc_data_txbuf() to avoid doing the
alignment converting operation and to catch possible invalid
alignment value in the future. Remove the 'if (data_align)'
checking too, as it is always true for a valid order-based
alignment value.

Fixes: 49489bb03a50 ("rxrpc: Do zerocopy using MSG_SPLICE_PAGES and page frags")

[BUG]
When running generic/287, the following file extent items can be
generated:
item 16 key (258 EXTENT_DATA 2682880) itemoff 15305 itemsize 53
generation 9 type 1 (regular)
extent data disk byte 1378414592 nr 462848
extent data offset 0 nr 462848 ram 2097152
extent compression 0 (none)
Note that file extent item is not a compressed one, but its ram_bytes is
way larger than its disk_num_bytes.
According to btrfs on-disk scheme, ram_bytes should match disk_num_bytes
if it's not a compressed one.
[CAUSE]
Since commit b73a6fd1b1ef ("btrfs: split partial dio bios before
submit"), for partial dio writes, we would split the ordered extent.
However the function btrfs_split_ordered_extent() doesn't update the
ram_bytes even it has already shrunk the disk_num_bytes.
Originally the function btrfs_split_ordered_extent() is only introduced
for zoned devices in commit d22002fd37bd ("btrfs: zoned: split ordered
extent when bio is sent"), but later commit b73a6fd1b1ef ("btrfs: split
partial dio bios before submit") makes non-zoned btrfs affected.
Thankfully for un-compressed file extent, we do not really utilize the
ram_bytes member, thus it won't cause any real problem.
[FIX]
Also update btrfs_ordered_extent::ram_bytes inside
btrfs_split_ordered_extent().
Fixes: d22002fd37bd ("btrfs: zoned: split ordered extent when bio is sent")

Pull workqueue fixes from Tejun Heo:
"Two doc update patches and the following three fixes:
- On single node systems, the default pool is used but the
node_nr_active for the default pool was set to min_active. This
effectively limited the max concurrency of unbound pools on single
node systems to 8 causing performance regressions on some
workloads. Fixed by setting the default pool's node_nr_active to
max_active.
- wq_update_node_max_active() could trigger divide-by-zero if the
intersection between the allowed CPUs for an unbound workqueue and
online CPUs becomes empty.
- When kick_pool() was trying to repatriate a worker to a CPU in its
pod by setting task->wake_cpu, it didn't consider whether the CPU
being selected is online or not which obviously can lead to
subobtimal behaviors. On s390, this triggered a crash in arch code.
The workqueue patch removes the gross misbehavior but doesn't fix
the crash completely as there's a race window in which CPUs can go
down after wake_cpu is set. Need to decide whether the fix should
be on the core or arch side"

Currently, we allocate a lbuf-sized kernel buffer and copy lbuf from
userspace to that buffer. Later, we use scanf on this buffer but we don't
ensure that the string is terminated inside the buffer, this can lead to
OOB read when using scanf. Fix this issue by using memdup_user_nul instead.

VXLAN stores per-VNI statistics using vxlan_vnifilter_count().
These statistics were not updated when arp_reduce() failed its
pskb_may_pull() call.
Use vxlan_vnifilter_count() to update the VNI counter when that
happens.

VXLAN devices update their stats locklessly. Therefore these counters
should either be stored in per-cpu data structures or the updates
should be done using atomic increments.
Since the net_device_core_stats infrastructure is already used in
vxlan_rcv(), use it for the other rx_dropped and tx_dropped counter
updates. Update the other counters atomically using DEV_STATS_INC().
