Pull workqueue updates from Tejun Heo: - Continued progress toward making alloc_workqueue() unbound by default: more callers converted to WQ_PERCPU / system_percpu_wq / system_dfl_wq, and new warnings for queues that use neither WQ_PERCPU nor WQ_UNBOUND or the legacy system_wq / system_unbound_wq. - Misc: drop the now-trivial apply_wqattrs_lock()/unlock() wrappers, forbid the TEST_WORKQUEUE benchmark from being built-in, and fix a spurious pointer level in the worker debug-dump path. * tag 'wq-for-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: drm/bridge: anx7625: Add WQ_PERCPU add to alloc_workqueue wifi: ath6kl: fix invalid workqueue flags in ath6kl_usb_create() btrfs: Drop WQ_PERCPU from ordered_flags in btrfs_init_workqueues() workqueue: Add warnings and ensure one among WQ_PERCPU or WQ_UNBOUND is present workqueue: Add warnings and fallback if system_{unbound}_wq is used workqueue: drop spurious '*' from print_worker_info() fn declaration workqueue: forbid TEST_WORKQUEUE from being built-in workqueue: drop apply_wqattrs_lock()/unlock() wrappers umh: replace use of system_unbound_wq with system_dfl_wq rapidio: rio: add WQ_PERCPU to alloc_workqueue users media: ddbridge: add WQ_PERCPU to alloc_workqueue users platform: cznic: turris-omnia-mcu: replace use of system_wq with system_percpu_wq media: synopsys: hdmirx: replace use of system_unbound_wq with system_dfl_wq virt: acrn: Add WQ_PERCPU to alloc_workqueue users

wifi: ath6kl: fix invalid workqueue flags in ath6kl_usb_create()

2026-06-14T22:02:09+00:00

ath6kl_usb_create() currently creates ath6kl_wq with flags set to 0: alloc_workqueue("ath6kl_wq", 0, 0) This triggers a runtime warning in __alloc_workqueue() because the queue is created with neither WQ_PERCPU nor WQ_UNBOUND set: workqueue: ath6kl_wq is using neither WQ_PERCPU or WQ_UNBOUND. Setting WQ_PERCPU. Set WQ_PERCPU explicitly to match the actual execution model and remove the warning during device probe. No functional change intended.

wifi: ath12k: enable IEEE80211_VHT_EXT_NSS_BW_CAPABLE when NSS ratio is reported

2026-06-09T13:50:29+00:00

When firmware reports NSS ratio support, SUPPORTS_VHT_EXT_NSS_BW is enabled in ath12k. However, IEEE80211_VHT_EXT_NSS_BW_CAPABLE must also be set to make the advertisement valid. According to IEEE Std 802.11-2024, Subclause 9.4.2.156.3 (Supported VHT-MCS and NSS Set subfields), the VHT Extended NSS BW Capable bit indicates whether a STA is capable of interpreting the Extended NSS BW Support subfield of the VHT capabilities information field. Advertising extended NSS BW support without setting this capability bit is therefore invalid. Without this change, mac80211 detects the inconsistency and logs: ieee80211 phy0: copying sband (band 1) due to VHT EXT NSS BW flag This indicates that mac80211 implicitly aligns IEEE80211_VHT_EXT_NSS_BW_CAPABLE during ieee80211_register_hw(). Explicitly setting the bit in ath12k avoids this fixup and ensures capabilities are advertised correctly by the driver. This change follows the same approach as the existing ath11k fix. https://lore.kernel.org/all/20211013073704.15888-1-wgong@codeaurora.org/ Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.5-01651-QCAHKSWPL_SILICONZ-1 Fixes: 18ab9d038fad ("wifi: ath12k: add support for 160 MHz bandwidth") Signed-off-by: Wen Gong Signed-off-by: Maharaja Kennadyrajan Reviewed-by: Rameshkumar Sundaram Link: https://patch.msgid.link/20260604095831.2674298-1-maharaja.kennadyrajan@oss.qualcomm.com Signed-off-by: Jeff Johnson

wifi: ath12k: fix EAPOL TX failure caused by stale tcl_metadata bits

2026-06-09T13:50:29+00:00

On WCN7850, after the following sequence: 1. load ath12k and connect to a non-MLO AP 2. disconnect and connect to an MLO AP 3. disconnect and reconnect to the non-MLO AP the third connection always fails with a 4-Way handshake timeout. The supplicant transmits message 2 of 4 four times in response to AP retries of message 1, but the AP never sees any of them. ath12k_dp_vdev_tx_attach() composes dp_link_vif->tcl_metadata using |=, but dp_link_vif is embedded in struct ath12k_dp_vif and its slots are reused across vif/peer teardown and setup. Since tcl_metadata is never cleared on detach, vdev_id bits from a previous attach remain set when the same link slot is reused with a different vdev_id. In this specific issue, the same link slot is used for vdev_id 0, then vdev_id 1, then vdev_id 0 again, the OR yields tcl_metadata == 0x9, which encodes vdev_id 1 in the HTT_TCL_META_DATA_VDEV_ID field even though ti.vdev_id is 0. Firmware then routes the EAPOL frame to the wrong vdev and the AP never receives message 2. Use plain assignment instead of |= so the field is fully recomputed from the current arvif on every attach.
