2025-08-15Bluetooth: hci_sync: Fix scan state after PA Sync has been establishedLuiz Augusto von Dentz
Passive scanning is used to program the address of the peer to be synchronized, so once HCI_EV_LE_PA_SYNC_ESTABLISHED is received it needs to be updated after clearing HCI_PA_SYNC then call hci_update_passive_scan_sync to return it to its original state.

2025-08-15perf: Avoid undefined behavior from stopping/starting inactive eventsYunseong Kim
Calling pmu->start()/stop() on perf events in PERF_EVENT_STATE_OFF can leave event->hw.idx at -1. When PMU drivers later attempt to use this negative index as a shift exponent in bitwise operations, it leads to UBSAN shift-out-of-bounds reports. The issue is a logical flaw in how event groups handle throttling when some members are intentionally disabled. Based on the analysis and the reproducer provided by Mark Rutland (this issue on both arm64 and x86-64). The scenario unfolds as follows: 1. A group leader event is configured with a very aggressive sampling period (e.g., sample_period = 1). This causes frequent interrupts and triggers the throttling mechanism. 2. A child event in the same group is created in a disabled state (.disabled = 1). This event remains in PERF_EVENT_STATE_OFF. Since it hasn't been scheduled onto the PMU, its event->hw.idx remains initialized at -1. 3. When throttling occurs, perf_event_throttle_group() and later perf_event_unthrottle_group() iterate through all siblings, including the disabled child event. 4. perf_event_throttle()/unthrottle() are called on this inactive child event, which then call event->pmu->start()/stop(). 5. The PMU driver receives the event with hw.idx == -1 and attempts to use it as a shift exponent. e.g., in macros like PMCNTENSET(idx), leading to the UBSAN report. The throttling mechanism attempts to start/stop events that are not actively scheduled on the hardware. Move the state check into perf_event_throttle()/perf_event_unthrottle() so that inactive events are skipped entirely. This ensures only active events with a valid hw.idx are processed, preventing undefined behavior and silencing UBSAN warnings. The corrected check ensures true before proceeding with PMU operations. The problem can be reproduced with the syzkaller reproducer: Fixes: 9734e25fbf5a ("perf: Fix the throttle logic for a group") Signed-off-by: Yunseong Kim <ysk@kzalloc.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Reviewed-by: Kan Liang <kan.liang@linux.intel.com> Link: https://lore.kernel.org/r/20250812181046.292382-2-ysk@kzalloc.com

2025-08-14net/sched: Fix backlog accounting in qdisc_dequeue_internalWilliam Liu
This issue applies for the following qdiscs: hhf, fq, fq_codel, and fq_pie, and occurs in their change handlers when adjusting to the new limit. The problem is the following in the values passed to the subsequent qdisc_tree_reduce_backlog call given a tbf parent: When the tbf parent runs out of tokens, skbs of these qdiscs will be placed in gso_skb. Their peek handlers are qdisc_peek_dequeued, which accounts for both qlen and backlog. However, in the case of qdisc_dequeue_internal, ONLY qlen is accounted for when pulling from gso_skb. This means that these qdiscs are missing a qdisc_qstats_backlog_dec when dropping packets to satisfy the new limit in their change handlers. One can observe this issue with the following (with tc patched to support a limit of 0): export TARGET=fq tc qdisc del dev lo root tc qdisc add dev lo root handle 1: tbf rate 8bit burst 100b latency 1ms tc qdisc replace dev lo handle 3: parent 1:1 $TARGET limit 1000 echo ''; echo 'add child'; tc -s -d qdisc show dev lo ping -I lo -f -c2 -s32 -W0.001 127.0.0.1 2>&1 >/dev/null echo ''; echo 'after ping'; tc -s -d qdisc show dev lo tc qdisc change dev lo handle 3: parent 1:1 $TARGET limit 0 echo ''; echo 'after limit drop'; tc -s -d qdisc show dev lo tc qdisc replace dev lo handle 2: parent 1:1 sfq echo ''; echo 'post graft'; tc -s -d qdisc show dev lo The second to last show command shows 0 packets but a positive number (74) of backlog bytes. The problem becomes clearer in the last show command, where qdisc_purge_queue triggers qdisc_tree_reduce_backlog with the positive backlog and causes an underflow in the tbf parent's backlog (4096 Mb instead of 0). To fix this issue, the codepath for all clients of qdisc_dequeue_internal has been simplified: codel, pie, hhf, fq, fq_pie, and fq_codel. qdisc_dequeue_internal handles the backlog adjustments for all cases that do not directly use the dequeue handler. The old fq_codel_change limit adjustment loop accumulated the arguments to the subsequent qdisc_tree_reduce_backlog call through the cstats field. However, this is confusing and error prone as fq_codel_dequeue could also potentially mutate this field (which qdisc_dequeue_internal calls in the non gso_skb case), so we have unified the code here with other qdiscs.

Submit multiple descriptors in axienet_rx_cb() to fill Rx skb ring. This ensures the ring "catches up" on previously missed allocations. Increment Rx skb ring head pointer after BD is successfully allocated. Previously, head pointer was incremented before verifying if descriptor is successfully allocated and has valid entries, which could lead to ring state inconsistency if descriptor setup failed.

Delete extra checks for the ATA_DFLAG_CDL_ENABLED flag that prevent SET FEATURES command from being issued to a drive when NCQ commands are active. ata_mselect_control_ata_feature() sets / clears the ATA_DFLAG_CDL_ENABLED flag during the translation of MODE SELECT to SET FEATURES. If SET FEATURES gets deferred due to outstanding NCQ commands, the original MODE SELECT command will be re-queued. When the re-queued MODE SELECT goes through the ata_mselect_control_ata_feature() translation again, SET FEATURES will not be issued because ATA_DFLAG_CDL_ENABLED has been already set or cleared by the initial translation of MODE SELECT. The ATA_DFLAG_CDL_ENABLED checks in ata_mselect_control_ata_feature() are safe to remove because scsi_cdl_enable() implements a similar logic that avoids enabling CDL if it has been enabled already.

2025-08-14drm/rockchip: vop2: make vp registers nonvolatilePiotr Zalewski
Make video port registers nonvolatile. As DSP_CTRL register is written to twice due to gamma LUT enable bit which is set outside of the main DSP_CTRL initialization within atomic_enable (for rk356x case it is also necessary to always disable gamma LUT before writing a new LUT) there is a chance that DSP_CTRL value read-out in gamma LUT init/update code is not the one which was written by the preceding DSP_CTRL initialization code within atomic_enable. This might result in misconfigured DSP_CTRL which leads to no visual output[1]. Since DSP_CTRL write takes effect after VSYNC[1] the issue is not always present. When tested on Pinetab2 with kernel 6.14 it happenes only when DRM is compiled as a module[1]. In order to confirm that it is a timing issue I inserted 18ms udelay before vop2_crtc_atomic_try_set_gamma in atomic enable and compiled DRM as module - this has also fixed the issue.

2025-08-14ata: libata-eh: Fix link state check for IDE/PATA portsDamien Le Moal
Commit 4371fe1ba400 ("ata: libata-eh: Avoid unnecessary resets when revalidating devices") replaced the call to ata_phys_link_offline() in ata_eh_revalidate_and_attach() with the new function ata_eh_link_established() which relaxes the checks on a device link state to account for low power mode transitions. However, this change assumed that the device port has a valid scr_read method to obtain the SStatus register for the port. This is not always the case, especially with older IDE/PATA adapters (e.g. PATA/IDE devices emulated with QEMU). For such adapter, ata_eh_link_established() will always return false, causing ata_eh_revalidate_and_attach() to go into its error path and ultimately to the device being disabled. Avoid this by restoring the previous behavior, which is to assume that the link is online if reading the port SStatus register fails. While at it, also fix the spelling of SStatus in the comment describing the function ata_eh_link_established().

Without setting phy_mask for ax88772 mdio bus, current driver may create at most 32 mdio phy devices with phy address range from 0x00 ~ 0x1f. DLink DUB-E100 H/W Ver B1 is such a device. However, only one main phy device will bind to net phy driver. This is creating issue during system suspend/resume since phy_polling_mode() in phy_state_machine() will directly deference member of phydev->drv for non-main phy devices.

syzbot found a race condition when kcm_unattach(psock) and kcm_release(kcm) are executed at the same time. kcm_unattach() is missing a check of the flag kcm->tx_stopped before calling queue_work(). If the kcm has a reserved psock, kcm_unattach() might get executed between cancel_work_sync() and unreserve_psock() in kcm_release(), requeuing kcm->tx_work right before kcm gets freed in kcm_done().

2025-08-13net/sched: ets: use old 'nbands' while purging unused classesDavide Caratti
Shuang reported sch_ets test-case [1] crashing in ets_class_qlen_notify() after recent changes from Lion [2]. The problem is: in ets_qdisc_change() we purge unused DWRR queues; the value of 'q->nbands' is the new one, and the cleanup should be done with the old one. The problem is here since my first attempts to fix ets_qdisc_change(), but it surfaced again after the recent qdisc len accounting fixes. Fix it purging idle DWRR queues before assigning a new value of 'q->nbands', so that all purge operations find a consistent configuration: - old 'q->nbands' because it's needed by ets_class_find() - old 'q->nstrict' because it's needed by ets_class_is_strict() BUG: kernel NULL pointer dereference, address: 0000000000000000 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: Oops: 0000 [#1] SMP NOPTI CPU: 62 UID: 0 PID: 39457 Comm: tc Kdump: loaded Not tainted 6.12.0-116.el10.x86_64 #1 PREEMPT(voluntary) Hardware name: Dell Inc.

2025-08-14rust: devres: fix leaking call to devm_add_action()Danilo Krummrich
When the data argument of Devres::new() is Err(), we leak the preceding call to devm_add_action(). In order to fix this, call devm_add_action() in a unit type initializer in try_pin_init!() after the initializers of all other fields.

From Frederic Weisbecker. 3) nf_tables should not allow to add a device to a flowtable or netdev chain more than once -- reject this. From Pablo Neira Ayuso.
