2025-05-23tpm_crb_ffa: use dev_xx() macro to print logYeoreum Yun
Instead of pr_xxx() macro, use dev_xxx() to print log. This patch changes some error log level to warn log level when the tpm_crb_ffa secure partition doesn't support properly but system can run without it.

2025-05-23tpm_ffa_crb: access tpm service over FF-A direct message request v2Yeoreum Yun
For secure partition with multi service, tpm_ffa_crb can access tpm service with direct message request v2 interface according to chapter 3.3, TPM Service Command Response Buffer Interface Over FF-A specificationi v1.0 BET. This patch reflects this spec to access tpm service over FF-A direct message request v2 ABI.

2025-05-23platform/x86/intel/pmc: Fix Arrow Lake U/H NPU PCI IDTodd Brandt
The ARL requires that the GMA and NPU devices both be in D3Hot in order for PC10 and S0iX to be achieved in S2idle. The original ARL-H/U addition to the intel_pmc_core driver attempted to do this by switching them to D3 in the init and resume calls of the intel_pmc_core driver. The problem is the ARL-H/U have a different NPU device and thus are not being properly set and thus S0iX does not work properly in ARL-H/U. This patch creates a new ARL-H specific device id that is correct and also adds the D3 fixup to the suspend callback. This way if the PCI devies drop from D3 to D0 after resume they can be corrected for the next suspend. Thus there is no dropout in S0iX.

2025-05-22selftests/tc-testing: Add an HFSC qlen accounting testCong Wang
This test reproduces a scenario where HFSC queue length and backlog accounting can become inconsistent when a peek operation triggers a dequeue and possible drop before the parent qdisc updates its counters. The test sets up a DRR root qdisc with an HFSC class, netem, and blackhole children, and uses Scapy to inject a packet. It helps to verify that HFSC correctly tracks qlen and backlog even when packets are dropped during peek-induced dequeue.

2025-05-22sch_hfsc: Fix qlen accounting bug when using peek in hfsc_enqueue()Cong Wang
When enqueuing the first packet to an HFSC class, hfsc_enqueue() calls the child qdisc's peek() operation before incrementing sch->q.qlen and sch->qstats.backlog. If the child qdisc uses qdisc_peek_dequeued(), this may trigger an immediate dequeue and potential packet drop. In such cases, qdisc_tree_reduce_backlog() is called, but the HFSC qdisc's qlen and backlog have not yet been updated, leading to inconsistent queue accounting. This can leave an empty HFSC class in the active list, causing further consequences like use-after-free. This patch fixes the bug by moving the increment of sch->q.qlen and sch->qstats.backlog before the call to the child qdisc's peek() operation. This ensures that queue length and backlog are always accurate when packet drops or dequeues are triggered during the peek.

2025-05-21io_uring/net: only retry recv bundle for a full transferJens Axboe
If a shorter than assumed transfer was seen, a partial buffer will have been filled. For that case it isn't sane to attempt to fill more into the bundle before posting a completion, as that will cause a gap in the received data. Check if the iterator has hit zero and only allow to continue a bundle operation if that is the case. Also ensure that for putting finished buffers, only the current transfer is accounted. Otherwise too many buffers may be put for a short transfer.

2025-05-21net: hibmcge: fix wrong ndo.open() after reset fail issue.Jijie Shao
If the driver reset fails, it may not work properly. Therefore, the ndo.open() operation should be rejected. In this patch, the driver calls netif_device_detach() before the reset and calls netif_device_attach() after the reset succeeds. If the reset fails, netif_device_attach() is not called. Therefore, netdev does not present and cannot be opened. If reset fails, only the PCI reset (via sysfs) can be used to attempt recovery.

2025-05-21nvme: avoid creating multipath sysfs group under namespace path devicesNilay Shroff
Commit 4dbd2b2ebe4c ("nvme-multipath: Add visibility for round-robin io-policy") introduced the creation of the multipath sysfs group under the NVMe head gendisk device node. However, it also inadvertently added the same sysfs group under each namespace path device which head node refers to and that is incorrect. The multipath sysfs group should only be exposed through the namespace head gendisk node. This is sufficient, as the head device already provides symbolic links to the individual namespace paths it manages. This patch fixes the issue by preventing the creation of the multipath sysfs group under namespace path devices, ensuring it only appears under the head disk node.

2025-05-21xsk: Bring back busy polling support in XDP_COPYSamiullah Khawaja
Commit 5ef44b3cb43b ("xsk: Bring back busy polling support") fixed the busy polling support in xsk for XDP_ZEROCOPY after it was broken in commit 86e25f40aa1e ("net: napi: Add napi_config"). The busy polling support with XDP_COPY remained broken since the napi_id setup in xsk_rcv_check was removed. Bring back the setup of napi_id for XDP_COPY so socket level SO_BUSYPOLL can be used to poll the underlying napi. Do the setup of napi_id for XDP_COPY in xsk_bind, as it is done currently for XDP_ZEROCOPY. The setup of napi_id for XDP_COPY in xsk_bind is safe because xsk_rcv_check checks that the rx queue at which the packet arrives is equal to the queue_id that was supplied in bind. This is done for both XDP_COPY and XDP_ZEROCOPY mode. Tested using AF_XDP support in virtio-net by running the xsk_rr AF_XDP benchmarking tool shared here: https://lore.kernel.org/all/20250320163523.3501305-1-skhawaja@google.com/T/ Enabled socket busy polling using following commands in qemu, ``` sudo ethtool -L eth0 combined 1 echo 400 | sudo tee /proc/sys/net/core/busy_read echo 100 | sudo tee /sys/class/net/eth0/napi_defer_hard_irqs echo 15000 | sudo tee /sys/class/net/eth0/gro_flush_timeout ``` Fixes: 5ef44b3cb43b ("xsk: Bring back busy polling support") Signed-off-by: Samiullah Khawaja <skhawaja@google.com> Reviewed-by: Willem de Bruijn <willemb@google.com> Acked-by: Stanislav Fomichev <sdf@fomichev.me> Signed-off-by: David S.

2025-05-21can: slcan: allow reception of short error messagesCarlos Sanchez
Allows slcan to receive short messages (typically errors) from the serial interface. When error support was added to slcan protocol in b32ff4668544e1333b694fcc7812b2d7397b4d6a ("can: slcan: extend the protocol with error info") the minimum valid message size changed from 5 (minimum standard can frame tIII0) to 3 ("e1a" is a valid protocol message, it is one of the examples given in the comments for slcan_bump_err() ), but the check for minimum message length prodicating all decoding was not adjusted. This makes short error messages discarded and error frames not being generated. This patch changes the minimum length to the new minimum (3 characters, excluding terminator, is now a valid message).

2025-05-21fs/buffer: optimize discard_buffer()Davidlohr Bueso
While invalidating, the clearing of the bits in discard_buffer() is done in one fully ordered CAS operation. In the past this was done via individual clear_bit(), until e7470ee89f0 (fs: buffer: do not use unnecessary atomic operations when discarding buffers). This implies that there were never strong ordering requirements outside of being serialized by the buffer lock. As such relax the ordering for archs that can benefit. Further, the implied ordering in buffer_unlock() makes current cmpxchg implied barrier redundant due to release semantics. And while in theory the unlock could be part of the bulk clearing, it is best to leave it explicit, but without the double barriers.
