+Subject: ASoC: SOF: Intel: hda-sdw-bpt: fix SND_SOF_SOF_HDA_SDW_BPT
+ dependencies
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+[ Upstream commit 614d416dd8aee2675fb591c598308a901a660db8 ]
+
+The hda-sdw-bpt code links against the soundwire driver, but that fails when
+trying to link from built-in code into loadable module:
+
+x86_64-linux-ld: vmlinux.o: in function `intel_ace2x_bpt_close_stream.isra.0':
+intel_ace2x.c:(.text+0x137a531): undefined reference to `hda_sdw_bpt_close'
+x86_64-linux-ld: vmlinux.o: in function `intel_ace2x_bpt_send_async':

+intel_ace2x.c:(.text+0x137aced): undefined reference to `hda_sdw_bpt_wait'
+
+Ensure that both SOUNDWIRE_INTEL and SND_SOF_SOF_HDA_SDW_BPT are selected
+at the same time by SND_SOC_SOF_INTEL_LNL, and that this happens even if
+SND_SOC_SOF_INTEL_SOUNDWIRE is a loadable module but SND_SOC_SOF_INTEL_LNL
+is built-in.
+
+This follows the same logic as commit c5a61db9bf89 ("ASoC: SOF: fix
+intel-soundwire link failure").

+Subject: block: Fix default IO priority if there is no IO context
+
+From: Guenter Roeck <linux@roeck-us.net>
+
+[ Upstream commit e2ba58ccc9099514380c3300cbc0750b5055fc1c ]
+
+Upstream commit 53889bcaf536 ("block: make __get_task_ioprio() easier to
+read") changes the IO priority returned to the caller if no IO context
+is defined for the task. Prior to this commit, the returned IO priority
+was determined by task_nice_ioclass() and task_nice_ioprio(). Now it is
+always IOPRIO_DEFAULT, which translates to IOPRIO_CLASS_NONE with priority
+0. However, task_nice_ioclass() returns IOPRIO_CLASS_IDLE, IOPRIO_CLASS_RT,
+or IOPRIO_CLASS_BE depending on the task scheduling policy, and
+task_nice_ioprio() returns a value determined by task_nice(). This causes
+regressions in test code checking the IO priority and class of IO
+operations on tasks with no IO context.
+
+Fix the problem by returning the IO priority calculated from
+task_nice_ioclass() and task_nice_ioprio() if no IO context is defined
+to match earlier behavior.

+Subject: eth: fbnic: remove the debugging trick of super high page bias
+
+From: Jakub Kicinski <kuba@kernel.org>
+
+[ Upstream commit e407fceeaf1b2959892b4fc9b584843d3f2bfc05 ]
+
+Alex added page bias of LONG_MAX, which is admittedly quite
+a clever way of catching overflows of the pp ref count.
+The page pool code was "optimized" to leave the ref at 1
+for freed pages so it can't catch basic bugs by itself any more.
+(Something we should probably address under DEBUG_NET...)
+
+Unfortunately for fbnic since commit f7dc3248dcfb ("skbuff: Optimization
+of SKB coalescing for page pool") core _may_ actually take two extra
+pp refcounts, if one of them is returned before driver gives up the bias
+the ret < 0 check in page_pool_unref_netmem() will trigger.
+
+While at it add a FBNIC_ to the name of the driver constant.

+Subject: ipa: fix compile-testing with qcom-mdt=m
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+[ Upstream commit 2df158047d532d0e2a6b39953656c738872151a3 ]
+
+There are multiple drivers that use the qualcomm mdt loader, but they
+have conflicting ideas of how to deal with that dependency when compile-testing
+for non-qualcomm targets:
+
+IPA only enables the MDT loader when the kernel config includes ARCH_QCOM,
+but the newly added ath12k support always enables it, which leads to a
+link failure with the combination of IPA=y and ATH12K=m:
+
+ aarch64-linux-ld: drivers/net/ipa/ipa_main.o: in function `ipa_firmware_load':
+ ipa_main.c:(.text.unlikely+0x134): undefined reference to `qcom_mdt_load
+
+The ATH12K method seems more reliable here, so change IPA over to do the same
+thing.

+
+Flags passed in for splice() syscall should not end up in
+skb_recv_datagram(). As SPLICE_F_NONBLOCK == MSG_PEEK, kernel gets
+confused: skb isn't unlinked from a receive queue, while strp_msg::offset
+and strp_msg::full_len are updated.
+
+Unbreak the logic a bit more by mapping both O_NONBLOCK and
+SPLICE_F_NONBLOCK to MSG_DONTWAIT. This way we align with man splice(2) in
+regard to errno EAGAIN:
+
+ SPLICE_F_NONBLOCK was specified in flags or one of the file descriptors
+ had been marked as nonblocking (O_NONBLOCK), and the operation would
+ block.

+md_spares_need_change in md_start_sync will call rdev_addable which
+protected by rcu_read_lock/rcu_read_unlock. This rcu context will help
+protect rdev won't be released, but rdev->mddev will be set to NULL
+before we call synchronize_rcu in md_kick_rdev_from_array. Fix this by
+using READ_ONCE and check does rdev->mddev still alive.

+Subject: md/md-cluster: handle REMOVE message earlier
+
+From: Heming Zhao <heming.zhao@suse.com>
+
+[ Upstream commit 948b1fe12005d39e2b49087b50e5ee55c9a8f76f ]
+
+Commit a1fd37f97808 ("md: Don't wait for MD_RECOVERY_NEEDED for
+HOT_REMOVE_DISK ioctl") introduced a regression in the md_cluster
+module. (Failed cases 02r1_Manage_re-add & 02r10_Manage_re-add)
+
+Consider a 2-node cluster:
+- node1 set faulty & remove command on a disk.
+- node2 must correctly update the array metadata.
+
+Before a1fd37f97808, on node1, the delay between msg:METADATA_UPDATED
+(triggered by faulty) and msg:REMOVE was sufficient for node2 to
+reload the disk info (written by node1).
+After a1fd37f97808, node1 no longer waits between faulty and remove,
+causing it to send msg:REMOVE while node2 is still reloading disk info.
+This often results in node2 failing to remove the faulty disk.
+
+== how to trigger ==
+
+set up a 2-node cluster (node1 & node2) with disks vdc & vdd.
+
+on node1:
+mdadm -CR /dev/md0 -l1 -b clustered -n2 /dev/vdc /dev/vdd --assume-clean
+ssh node2-ip mdadm -A /dev/md0 /dev/vdc /dev/vdd
+mdadm --manage /dev/md0 --fail /dev/vdc --remove /dev/vdc
+
+check array status on both nodes with "mdadm -D /dev/md0".
+node1 output:
+ Number Major Minor RaidDevice State
+ - 0 0 0 removed
+ 1 254 48 1 active sync /dev/vdd
+node2 output:
+ Number Major Minor RaidDevice State
+ - 0 0 0 removed
+ 1 254 48 1 active sync /dev/vdd
+
+ 0 254 32 - faulty /dev/vdc

+From: Lorenzo Bianconi <lorenzo@kernel.org>
+
+[ Upstream commit 38358fa3cc8e16c6862a3e5c5c233f9f652e3a6d ]
+
+In order to avoid any possible race we need to hold the ppe_lock
+spinlock accessing the hw PPE table. airoha_ppe_foe_get_entry routine is

+To trigger gso segment in udp_queue_rcv_skb(), we should also set option
+UDP_ENCAP_ESPINUDP to enable udp_sk(sk)->encap_rcv. When the encap_rcv
+hook return 1 in udp_queue_rcv_one_skb(), udp_csum_pull_header() will try
+to pull udphdr, but the skb size has been segmented to gso size, which
+leads to this crash.

+introduces segmentation in UDP receive path only for GRO, which was never
+intended to be used for UFO, so drop UFO packets in udp_rcv_segment().

+From: Florian Fainelli <florian.fainelli@broadcom.com>
+
+[ Upstream commit a81649a4efd382497bf3d34a623360263adc6993 ]
+
+When the parent clock is a gated clock which has multiple parents, the
+clock provider (clk-scmi typically) might return a rate of 0 since there
+is not one of those particular parent clocks that should be chosen for
+returning a rate. Prior to ee975351cf0c ("net: mdio: mdio-bcm-unimac:
+Manage clock around I/O accesses"), we would not always be passing a
+clock reference depending upon how mdio-bcm-unimac was instantiated. In
+that case, we would take the fallback path where the rate is hard coded
+to 250MHz.
+
+Make sure that we still fallback to using a fixed rate for the divider
+calculation, otherwise we simply ignore the desired MDIO bus clock
+frequency which can prevent us from interfacing with Ethernet PHYs
+properly.

+Subject: net/mlx5: Correctly set gso_segs when LRO is used
+
+From: Christoph Paasch <cpaasch@openai.com>
+
+[ Upstream commit 77bf1c55b2acc7fa3734b14f4561e3d75aea1a90 ]
+
+When gso_segs is left at 0, a number of assumptions will end up being
+incorrect throughout the stack.
+
+For example, in the GRO-path, we set NAPI_GRO_CB()->count to gso_segs.
+So, if a non-LRO'ed packet followed by an LRO'ed packet is being
+processed in GRO, the first one will have NAPI_GRO_CB()->count set to 1 and
+the next one to 0 (in dev_gro_receive()).
+Since commit 531d0d32de3e
+("net/mlx5: Correctly set gso_size when LRO is used")
+these packets will get merged (as their gso_size now matches).
+So, we end up in gro_complete() with NAPI_GRO_CB()->count == 1 and thus
+don't call inet_gro_complete(). Meaning, checksum-validation in
+tcp_checksum_complete() will fail with a "hw csum failure".
+
+Even before the above mentioned commit, incorrect gso_segs means that other
+things like TCP's accounting of incoming packets (tp->segs_in,
+data_segs_in, rcv_ooopack) will be incorrect. Which means that if one
+does bytes_received/data_segs_in, the result will be bigger than the
+MTU.
+
+Fix this by initializing gso_segs correctly when LRO is used.

+Subject: net/sched: taprio: enforce minimum value for picos_per_byte
+
+From: Takamitsu Iwai <takamitz@amazon.co.jp>
+
+[ Upstream commit ae8508b25def57982493c48694ef135973bfabe0 ]
+
+Syzbot reported a WARNING in taprio_get_start_time().
+
+When link speed is 470,589 or greater, q->picos_per_byte becomes too
+small, causing length_to_duration(q, ETH_ZLEN) to return zero.
+
+This zero value leads to validation failures in fill_sched_entry() and
+parse_taprio_schedule(), allowing arbitrary values to be assigned to
+entry->interval and cycle_time. As a result, sched->cycle can become zero.
+
+Since SPEED_800000 is the largest defined speed in
+include/uapi/linux/ethtool.h, this issue can occur in realistic scenarios.
+
+To ensure length_to_duration() returns a non-zero value for minimum-sized
+Ethernet frames (ETH_ZLEN = 60), picos_per_byte must be at least 17
+(60 * 17 > PSEC_PER_NSEC which is 1000).
+
+This patch enforces a minimum value of 17 for picos_per_byte when the
+calculated value would be lower, and adds a warning message to inform
+users that scheduling accuracy may be affected at very high link speeds.
+
+Fixes: fb66df20a720 ("net/sched: taprio: extend minimum interval restriction to entire cycle too")

+Subject: netpoll: prevent hanging NAPI when netcons gets enabled
+
+From: Jakub Kicinski <kuba@kernel.org>
+
+[ Upstream commit 2da4def0f487f24bbb0cece3bb2bcdcb918a0b72 ]
+
+Paolo spotted hangs in NIPA running driver tests against virtio.
+The tests hang in virtnet_close() -> virtnet_napi_tx_disable().
+
+The problem is only reproducible if running multiple of our tests
+in sequence (I used TEST_PROGS="xdp.py ping.py netcons_basic.sh \
+netpoll_basic.py stats.py"). Initial suspicion was that this is
+a simple case of double-disable of NAPI, but instrumenting the
+code reveals:
+
+ Deadlocked on NAPI ffff888007cd82c0 (virtnet_poll_tx):
+ state: 0x37, disabled: false, owner: 0, listed: false, weight: 64
+
+The NAPI was not in fact disabled, owner is 0 (rather than -1),
+so the NAPI "thinks" it's scheduled for CPU 0 but it's not listed
+(!list_empty(&n->poll_list) => false). It seems odd that normal NAPI
+processing would wedge itself like this.
+
+Better suspicion is that netpoll gets enabled while NAPI is polling,
+and also grabs the NAPI instance. This confuses napi_complete_done():
+
+ [netpoll] [normal NAPI]
+ napi_poll()
+ have = netpoll_poll_lock()
+ rcu_access_pointer(dev->npinfo)
+ return NULL # no netpoll
+ __napi_poll()
+ ->poll(->weight)
+ poll_napi()
+ cmpxchg(->poll_owner, -1, cpu)
+ poll_one_napi()
+ set_bit(NAPI_STATE_NPSVC, ->state)
+ napi_complete_done()
+ if (NAPIF_STATE_NPSVC)
+ return false
+ # exit without clearing SCHED
+
+This feels very unlikely, but perhaps virtio has some interactions
+with the hypervisor in the NAPI ->poll that makes the race window
+larger?
+
+Best I could to to prove the theory was to add and trigger this
+warning in napi_poll (just before netpoll_poll_unlock()):
+
+ WARN_ONCE(!have && rcu_access_pointer(n->dev->npinfo) &&
+ napi_is_scheduled(n) && list_empty(&n->poll_list),
+ "NAPI race with netpoll %px", n);
+
+If this warning hits the next virtio_close() will hang.
+
+This patch survived 30 test iterations without a hang (without it
+the longest clean run was around 10). Credit for triggering this
+goes to Breno's recent netconsole tests.

+Subject: NFS: Fixup allocation flags for nfsiod's __GFP_NORETRY
+
+From: Benjamin Coddington <bcodding@redhat.com>
+
+[ Upstream commit 99765233ab42bf7a4950377ad7894dce8a5c0e60 ]
+
+If the NFS client is doing writeback from a workqueue context, avoid using
+__GFP_NORETRY for allocations if the task has set PF_MEMALLOC_NOIO or
+PF_MEMALLOC_NOFS. The combination of these flags makes memory allocation
+failures much more likely.
+
+We've seen those allocation failures show up when the loopback driver is
+doing writeback from a workqueue to a file on NFS, where memory allocation
+failure results in errors or corruption within the loopback device's
+filesystem.

+
+Commit 528589947c180 ("nvmet: initialize discovery subsys after debugfs
+is initialized") changed nvmet_init() to initialize nvme discovery after
+"nvmet" debugfs directory is initialized. The change broke nvmet_exit()

+
+[ Upstream commit 528589947c1802b9357c2a9b96d88cc4a11cd88b ]
+
+During nvme target initialization discovery subsystem is initialized
+before "nvmet" debugfs directory is created. This results in discovery
+subsystem debugfs directory to be created in debugfs root directory.
+
+nvmet_init() ->
+ nvmet_init_discovery() ->
+ nvmet_subsys_alloc() ->
+ nvmet_debugfs_subsys_setup()
+
+In other words, the codepath above is exeucted before nvmet_debugfs is
+created. We get /sys/kernel/debug/nqn.2014-08.org.nvmexpress.discovery
+instead of /sys/kernel/debug/nvmet/nqn.2014-08.org.nvmexpress.discovery.
+Move nvmet_init_discovery() call after nvmet_init_debugfs() to fix it.

+
+[ Upstream commit 6fb5ff63b35b7e849cc8510957f25753f87f63d2 ]
+
+According to the 1588 standard, it is possible to use both unicast and
+multicast frames to send the PTP information. It was noticed that if the
+frames were unicast they were not processed by the analyzer meaning that
+they were not timestamped. Therefore fix this to match also these
+unicast frames.

+Subject: pNFS/flexfiles: don't attempt pnfs on fatal DS errors
+
+From: Tigran Mkrtchyan <tigran.mkrtchyan@desy.de>
+
+[ Upstream commit f06bedfa62d57f7b67d44aacd6badad2e13a803f ]
+
+When an applications get killed (SIGTERM/SIGINT) while pNFS client performs a connection
+to DS, client ends in an infinite loop of connect-disconnect. This
+source of the issue, it that flexfilelayoutdev#nfs4_ff_layout_prepare_ds gets an error
+on nfs4_pnfs_ds_connect with status ERESTARTSYS, which is set by rpc_signal_task, but
+the error is treated as transient, thus retried.
+
+The issue is reproducible with Ctrl+C the following script(there should be ~1000 files in
+a directory, client should must not have any connections to DSes):
+
+```
+echo 3 > /proc/sys/vm/drop_caches
+
+for i in *
+do
+ head -1 $i
+done
+```
+
+The change aims to propagate the nfs4_ff_layout_prepare_ds error state
+to the caller that can decide whatever this is a retryable error or not.

+Subject: Revert "net: mdio_bus: Use devm for getting reset GPIO"
+
+From: Jakub Kicinski <kuba@kernel.org>
+
+[ Upstream commit 175811b8f05f0da3e19b7d3124666649ddde3802 ]
+
+This reverts commit 3b98c9352511db627b606477fc7944b2fa53a165.
+
+Russell says:
+
+ Using devm_*() [here] is completely wrong, because this is called
+ from mdiobus_register_device(). This is not the probe function
+ for the device, and thus there is no code to trigger the release of
+ the resource on unregistration.
+
+ Moreover, when the mdiodev is eventually probed, if the driver fails
+ or the driver is unbound, the GPIO will be released, but a reference
+ will be left behind.
+
+ Using devm* with a struct device that is *not* currently being probed
+ is fundamentally wrong - an abuse of devm.

+Subject: s390/mm: Set high_memory at the end of the identity mapping
+
+From: Alexander Gordeev <agordeev@linux.ibm.com>
+
+[ Upstream commit 56f4cfab1c93b14da422cdcd23898eb008033696 ]
+
+The value of high_memory variable is set by set_high_memory() function
+to a value returned by memblock_end_of_DRAM(). The latter function
+returns by default the upper bound of the last online memory block,
+not the upper bound of the directly mapped memory region. As result,
+in case the end of memory happens to be offline, high_memory variable
+is set to a value that is short on the last offline memory blocks size:
+
+RANGE SIZE STATE REMOVABLE BLOCK
+0x0000000000000000-0x000000ffffffffff 1T online yes 0-511
+0x0000010000000000-0x0000011fffffffff 128G offline 512-575
+
+Memory block size: 2G
+Total online memory: 1T
+Total offline memory: 128G
+
+crash> p/x vm_layout
+$1 = {
+ kaslr_offset = 0x3453e918000,
+ kaslr_offset_phys = 0xa534218000,
+ identity_base = 0x0,
+ identity_size = 0x12000000000
+}
+crash> p/x high_memory
+$2 = 0x10000000000
+
+In the past the value of high_memory was derived from max_low_pfn,
+which in turn was derived from the identity_size. Since identity_size
+accommodates the whole memory size - including tailing offline blocks,
+the offlined blocks did not impose any problem. But since commit
+e120d1bc12da ("arch, mm: set high_memory in free_area_init()") the
+value of high_memory is derived from the last memblock online region,
+and that is where the problem comes from.
+
+The value of high_memory is used by several drivers and by external
+tools (e.g. crash tool aborts while loading a dump).
+
+Similarily to ARM, use the override path provided by set_high_memory()
+function and set the value of high_memory at the end of the identity
+mapping early. That forces set_high_memory() to leave in high_memory
+the correct value, even when the end of available memory is offline.
+
+Fixes: e120d1bc12da ("arch, mm: set high_memory in free_area_init()")

+From: Stefan Metzmacher <metze@samba.org>
+

+
+Calling enqueue_reassembly() and wake_up_interruptible(&info->wait_reassembly_queue)
+or put_receive_buffer() means the response/data_transfer pointer might
+get re-used by another thread, which means these should be
+the last operations before calling return.

+Subject: smb: client: let recv_done() cleanup before notifying the callers.
+
+From: Stefan Metzmacher <metze@samba.org>
+
+[ Upstream commit bdd7afc6dca5e0ebbb75583484aa6ea9e03fbb13 ]
+
+We should call put_receive_buffer() before waking up the callers.
+
+For the internal error case of response->type being unexpected,
+we now also call smbd_disconnect_rdma_connection() instead
+of not waking up the callers at all.
+
+Note that the SMBD_TRANSFER_DATA case still has problems,
+which will be addressed in the next commit in order to make
+it easier to review this one.

+
+There's no need to maintain two lists, we can just
+have a single list of receive buffers, which are free to use.
+
+It just added unneeded complexity and resulted in
+ib_dma_unmap_single() not being called from recv_done()

+From: Simon Trimmer <simont@opensource.cirrus.com>
+
+[ Upstream commit ffcfd071eec7973e58c4ffff7da4cb0e9ca7b667 ]
+
+The software node does not specify a count of property entries, so the
+array must be null-terminated.
+
+When unterminated, this can lead to a fault in the downstream cs35l56
+amplifier driver, because the node parse walks off the end of the
+array into unknown memory.

+Subject: sunrpc: fix client side handling of tls alerts
+
+From: Olga Kornievskaia <okorniev@redhat.com>
+
+[ Upstream commit cc5d59081fa26506d02de2127ab822f40d88bc5a ]
+
+A security exploit was discovered in NFS over TLS in tls_alert_recv
+due to its assumption that there is valid data in the msghdr's
+iterator's kvec.
+
+Instead, this patch proposes the rework how control messages are
+setup and used by sock_recvmsg().
+
+If no control message structure is setup, kTLS layer will read and
+process TLS data record types. As soon as it encounters a TLS control
+message, it would return an error. At that point, NFS can setup a kvec
+backed control buffer and read in the control message such as a TLS
+alert. Scott found that a msg iterator can advance the kvec pointer
+as a part of the copy process thus we need to revert the iterator
+before calling into the tls_alert_recv.

+
+Together with the RAPL MSRs, there are more MSRs gone on DMR, including

+Subject: x86/irq: Plug vector setup race
+
+From: Thomas Gleixner <tglx@linutronix.de>
+
+[ Upstream commit ce0b5eedcb753697d43f61dd2e27d68eb5d3150f ]
+
+Hogan reported a vector setup race, which overwrites the interrupt
+descriptor in the per CPU vector array resulting in a disfunctional device.
+
+CPU0 CPU1
+ interrupt is raised in APIC IRR
+ but not handled
+ free_irq()
+ per_cpu(vector_irq, CPU1)[vector] = VECTOR_SHUTDOWN;
+
+ request_irq() common_interrupt()
+ d = this_cpu_read(vector_irq[vector]);
+
+ per_cpu(vector_irq, CPU1)[vector] = desc;
+
+ if (d == VECTOR_SHUTDOWN)
+ this_cpu_write(vector_irq[vector], VECTOR_UNUSED);
+
+free_irq() cannot observe the pending vector in the CPU1 APIC as there is
+no way to query the remote CPUs APIC IRR.
+
+This requires that request_irq() uses the same vector/CPU as the one which
+was freed, but this also can be triggered by a spurious interrupt.
+
+Interestingly enough this problem managed to be hidden for more than a
+decade.
+
+Prevent this by reevaluating vector_irq under the vector lock, which is
+held by the interrupt activation code when vector_irq is updated.
+
+To avoid ifdeffery or IS_ENABLED() nonsense, move the
+[un]lock_vector_lock() declarations out under the
+CONFIG_IRQ_DOMAIN_HIERARCHY guard as it's only provided when
+CONFIG_X86_LOCAL_APIC=y.
+
+The current CONFIG_IRQ_DOMAIN_HIERARCHY guard is selected by
+CONFIG_X86_LOCAL_APIC, but can also be selected by other parts of the
+Kconfig system, which makes 32-bit UP builds with CONFIG_X86_LOCAL_APIC=n
+fail.
+
+Can we just get rid of this !APIC nonsense once and forever?
