When restoring the default socket callbacks during a TLS handshake, we need to acquire a write lock on sk_callback_lock.

2025-07-15nvme: fix misaccounting of nvme-mpath inflight I/OYu Kuai
Procedures for nvme-mpath IO accounting: 1) initialize nvme_request and clear flags; 2) set NVME_MPATH_IO_STATS and increase inflight counter when IO started; 3) check NVME_MPATH_IO_STATS and decrease inflight counter when IO is done; However, for the case nvme_fail_nonready_command(), both step 1) and 2) are skipped, and if old nvme_request set NVME_MPATH_IO_STATS and then request is reused, step 3) will still be executed, causing inflight I/O counter to be negative. Fix the problem by clearing nvme_request in nvme_fail_nonready_command().

2025-07-15nvme: revert the cross-controller atomic write size validationChristoph Hellwig
This was originally added by commit 8695f060a029 ("nvme: all namespaces in a subsystem must adhere to a common atomic write size") to check the all controllers in a subsystem report the same atomic write size, but the check wasn't quite correct and caused problems for devices with multiple namespaces that report different LBA sizes. Commit f46d273449ba ("nvme: fix atomic write size validation") tried to fix this, but then caused problems for namespace rediscovery after a format with an LBA size change that changes the AWUPF value. This drops the validation and essentially reverts those two commits while keeping the cleanup that went in between the two. We'll need to figure out how to properly check for the mouse trap that nvme left us, but for now revert the check to keep devices working for users who couldn't care less about the atomic write feature.

Size of ring buffer, as defined in uio_hv_generic driver, is no longer fixed to 16 KB. This creates a problem in fcopy, since this size was hardcoded. With the change in place to make ring sysfs node actually reflect the size of underlying ring buffer, it is safe to get the size of ring sysfs file and use it for ring buffer size in fcopy daemon. Fix the issue of disparity in ring buffer size, by making it dynamic in fcopy uio daemon.

2025-07-15wifi: rtw89: introduce fw feature group and redefine CRASH_TRIGGERZong-Zhe Yang
Some FW features may have variants on how to deal with in leaf functions, e.g. H2C commands. However, from SW component point of view, it might not matter which variant is supported exactly. In some cases, SW component may just care whether any of the variants is supported or not. So, introduce a concept of FW feature group which can manage a set of FW features and can easily be checked if at least one of them is supported.

2025-07-15wifi: rtw89: mcc: solve GO's TBTT change and TBTT too close to NoA issueChih-Kang Chang
For some implementation acting as GO under MCC(GO+STA), the GO's TBTT might change after STA roams to another AP. This could result the new GO beacon TX at the STA timeslot of GC+STA, causing GC beacon loss. Therefore, if the GC detects beacon loss, it will pause MCC and remain on the GO side for 100 TU to detect the new TBTT beacon. Additionally, some implementation acting as GO under MCC might TX beacon too close to the NoA period. The GC calculates timeslot pattern the TOB (time offset behind) or TOA(time offset ahead) less than the minimum RX beacon time, which leads to beacon loss. Therefore, disable the beacon filter in this case. Then, if the GO's TBTT changed, the pattern TOB/TOA greater than the minimum RX beacon time, the beacon filter should be retriggered during MCC update. Moreover, if the beacon filter is disabled initially but the GO timeslot change, causing QoS null data detection fail, also pause MCC to detect new TBTT beacon.

HW scan of WiFi 7 chips supports multiple op channel configurations. When concurrency, fill two channels info to HW scan to avoid packet lost. However, the OP chan timing is arranged by FW, and the actual stay period depends on AP. It's hard to calculate total scan time for once NoA in advance. Therefore, change the scan back to GO OP channel every 200TU and TX beacon to ensure GC doesn't beacon loss. Additionally, add a period NoA with large duration to ensure GC doesn't TX packet during GO scanning and can still listen beacon at TBTT to update the new NoA info after scan complete.

Packet detection(PD) lower bound is the threshold for sensing packet, and it is dynamically calculated based on RSSI. In MCC, the two interfaces have different RSSI values, so it is necessary to set different values to ensure packets can be received. Therefore, add H2C command to let firmware to switch PD lower bound when MCC mode.

2025-07-14Add support to set NAPI threaded for individual NAPISamiullah Khawaja
A net device has a threaded sysctl that can be used to enable threaded NAPI polling on all of the NAPI contexts under that device. Allow enabling threaded NAPI polling at individual NAPI level using netlink. Extend the netlink operation `napi-set` and allow setting the threaded attribute of a NAPI. This will enable the threaded polling on a NAPI context. Add a test in `nl_netdev.py` that verifies various cases of threaded NAPI being set at NAPI and at device level.

2025-07-14net: phy: Don't register LEDs for genphySean Anderson
If a PHY has no driver, the genphy driver is probed/removed directly in phy_attach/detach. If the PHY's ofnode has an "leds" subnode, then the LEDs will be (un)registered when probing/removing the genphy driver. This could occur if the leds are for a non-generic driver that isn't loaded for whatever reason. Synchronously removing the PHY device in phy_detach leads to the following deadlock: rtnl_lock() ndo_close() ... phy_detach() phy_remove() phy_leds_unregister() led_classdev_unregister() led_trigger_set() netdev_trigger_deactivate() unregister_netdevice_notifier() rtnl_lock() There is a corresponding deadlock on the open/register side of things (and that one is reported by lockdep), but it requires a race while this one is deterministic. Regular drivers do not have this problem since they are probed asynchronously (without RTNL held). Generic PHYs do not support LEDs anyway, so don't bother registering them.

2025-07-14netdevsim: implement peer queue flow controlBreno Leitao
Add flow control mechanism between paired netdevsim devices to stop the TX queue during high traffic scenarios. When a receive queue becomes congested (approaching NSIM_RING_SIZE limit), the corresponding transmit queue on the peer device is stopped using netif_subqueue_try_stop(). Once the receive queue has sufficient capacity again, the peer's transmit queue is resumed with netif_tx_wake_queue(). Key changes: * Add nsim_stop_peer_tx_queue() to pause peer TX when RX queue is full * Add nsim_start_peer_tx_queue() to resume peer TX when RX queue drains * Implement queue mapping validation to ensure TX/RX queue count match * Wake all queues during device unlinking to prevent stuck queues * Use RCU protection when accessing peer device references * wake the queues when changing the queue numbers * Remove IFF_NO_QUEUE given it will enqueue packets now The flow control only activates when devices have matching TX/RX queue counts to ensure proper queue mapping.
