2025-07-15net: libwx: fix the using of Rx buffer DMAJiawen Wu
The wx_rx_buffer structure contained two DMA address fields: 'dma' and 'page_dma'. However, only 'page_dma' was actually initialized and used to program the Rx descriptor. But 'dma' was uninitialized and used in some paths. This could lead to undefined behavior, including DMA errors or use-after-free, if the uninitialized 'dma' was used. Althrough such error has not yet occurred, it is worth fixing in the code.

2025-07-15net: libwx: remove duplicate page_pool_put_full_page()Jiawen Wu
page_pool_put_full_page() should only be invoked when freeing Rx buffers or building a skb if the size is too short. At other times, the pages need to be reused. So remove the redundant page put. In the original code, double free pages cause kernel panic: [ 876.949834] __irq_exit_rcu+0xc7/0x130 [ 876.949836] common_interrupt+0xb8/0xd0 [ 876.949838] </IRQ> [ 876.949838] <TASK> [ 876.949840] asm_common_interrupt+0x22/0x40 [ 876.949841] RIP: 0010:cpuidle_enter_state+0xc2/0x420 [ 876.949843] Code: 00 00 e8 d1 1d 5e ff e8 ac f0 ff ff 49 89 c5 0f 1f 44 00 00 31 ff e8 cd fc 5c ff 45 84 ff 0f 85 40 02 00 00 fb 0f 1f 44 00 00 <45> 85 f6 0f 88 84 01 00 00 49 63 d6 48 8d 04 52 48 8d 04 82 49 8d [ 876.949844] RSP: 0018:ffffaa7340267e78 EFLAGS: 00000246 [ 876.949845] RAX: ffff9e3f135be000 RBX: 0000000000000002 RCX: 0000000000000000 [ 876.949846] RDX: 000000cc2dc4cb7c RSI: ffffffff89ee49ae RDI: ffffffff89ef9f9e [ 876.949847] RBP: ffff9e378f940800 R08: 0000000000000002 R09: 00000000000000ed [ 876.949848] R10: 000000000000afc8 R11: ffff9e3e9e5a9b6c R12: ffffffff8a6d8580 [ 876.949849] R13: 000000cc2dc4cb7c R14: 0000000000000002 R15: 0000000000000000 [ 876.949852] ? cpuidle_enter_state+0xb3/0x420 [ 876.949855] cpuidle_enter+0x29/0x40 [ 876.949857] cpuidle_idle_call+0xfd/0x170 [ 876.949859] do_idle+0x7a/0xc0 [ 876.949861] cpu_startup_entry+0x25/0x30 [ 876.949862] start_secondary+0x117/0x140 [ 876.949864] common_startup_64+0x13e/0x148 [ 876.949867] </TASK> [ 876.949868] ---[ end trace 0000000000000000 ]--- [ 876.949869] ------------[ cut here ]------------ [ 876.949870] list_del corruption, ffffead40445a348->next is NULL [ 876.949873] WARNING: CPU: 14 PID: 0 at lib/list_debug.c:52 __list_del_entry_valid_or_report+0x67/0x120 [ 876.949875] Modules linked in: snd_hrtimer(E) bnep(E) binfmt_misc(E) amdgpu(E) squashfs(E) vfat(E) loop(E) fat(E) amd_atl(E) snd_hda_codec_realtek(E) intel_rapl_msr(E) snd_hda_codec_generic(E) intel_rapl_common(E) snd_hda_scodec_component(E) snd_hda_codec_hdmi(E) snd_hda_intel(E) edac_mce_amd(E) snd_intel_dspcfg(E) snd_hda_codec(E) snd_hda_core(E) amdxcp(E) kvm_amd(E) snd_hwdep(E) gpu_sched(E) drm_panel_backlight_quirks(E) cec(E) snd_pcm(E) drm_buddy(E) snd_seq_dummy(E) drm_ttm_helper(E) btusb(E) kvm(E) snd_seq_oss(E) btrtl(E) ttm(E) btintel(E) snd_seq_midi(E) btbcm(E) drm_exec(E) snd_seq_midi_event(E) i2c_algo_bit(E) snd_rawmidi(E) bluetooth(E) drm_suballoc_helper(E) irqbypass(E) snd_seq(E) ghash_clmulni_intel(E) sha512_ssse3(E) drm_display_helper(E) aesni_intel(E) snd_seq_device(E) rfkill(E) snd_timer(E) gf128mul(E) drm_client_lib(E) drm_kms_helper(E) snd(E) i2c_piix4(E) joydev(E) soundcore(E) wmi_bmof(E) ccp(E) k10temp(E) i2c_smbus(E) gpio_amdpt(E) i2c_designware_platform(E) gpio_generic(E) sg(E) [ 876.949914] i2c_designware_core(E) sch_fq_codel(E) parport_pc(E) drm(E) ppdev(E) lp(E) parport(E) fuse(E) nfnetlink(E) ip_tables(E) ext4 crc16 mbcache jbd2 sd_mod sfp mdio_i2c i2c_core txgbe ahci ngbe pcs_xpcs libahci libwx r8169 phylink libata realtek ptp pps_core video wmi [ 876.949933] CPU: 14 UID: 0 PID: 0 Comm: swapper/14 Kdump: loaded Tainted: G W E 6.16.0-rc2+ #20 PREEMPT(voluntary) [ 876.949935] Tainted: [W]=WARN, [E]=UNSIGNED_MODULE [ 876.949936] Hardware name: Micro-Star International Co., Ltd.

2025-07-15dmaengine: nbpfaxi: Fix memory corruption in probe()Dan Carpenter
The nbpf->chan[] array is allocated earlier in the nbpf_probe() function and it has "num_channels" elements. These three loops iterate one element farther than they should and corrupt memory. The changes to the second loop are more involved. In this case, we're copying data from the irqbuf[] array into the nbpf->chan[] array. If the data in irqbuf[i] is the error IRQ then we skip it, so the iterators are not in sync. I added a check to ensure that we don't go beyond the end of the irqbuf[] array. I'm pretty sure this can't happen, but it seemed harmless to add a check. On the other hand, after the loop has ended there is a check to ensure that the "chan" iterator is where we expect it to be. In the original code we went one element beyond the end of the array so the iterator wasn't in the correct place and it would always return -EINVAL. However, now it will always be in the correct place. I deleted the check since we know the result.

2025-07-15drm/dp: Change AUX DPCD probe address from LANE0_1_STATUS to ↵Imre Deak
TRAINING_PATTERN_SET Commit a3ef3c2da675 ("drm/dp: Change AUX DPCD probe address from DPCD_REV to LANE0_1_STATUS") stopped using the DPCD_REV register for DPCD probing, since this results in link training failures at least when using an Intel Barlow Ridge TBT hub at UHBR link rates (the DP_INTRA_HOP_AUX_REPLY_INDICATION never getting cleared after the failed link training). Since accessing DPCD_REV during link training is prohibited by the DP Standard, LANE0_1_STATUS (0x202) was used instead, as it falls within the Standard's valid register address range (0x102-0x106, 0x202-0x207, 0x200c-0x200f, 0x2216) and it fixed the link training on the above TBT hub. However, reading the LANE0_1_STATUS register also has a side-effect at least on a Novatek eDP panel, as reported on the Closes: link below, resulting in screen flickering on that panel. One clear side-effect when doing the 1-byte probe reads from LANE0_1_STATUS during link training before reading out the full 6 byte link status starting at the same address is that the panel will report the link training as completed with voltage swing 0. This is different from the normal, flicker-free scenario when no DPCD probing is done, the panel reporting the link training complete with voltage swing 2. Using the TRAINING_PATTERN_SET register for DPCD probing doesn't have the above side-effect, the panel will link train with voltage swing 2 as expected and it will stay flicker-free. This register is also in the above valid register range and is unlikely to have a side-effect as that of LANE0_1_STATUS: Reading LANE0_1_STATUS is part of the link training CR/EQ sequences and so it may cause a state change in the sink - even if inadvertently as I suspect in the case of the above Novatek panel. As opposed to this, reading TRAINING_PATTERN_SET is not part of the link training sequence (it must be only written once at the beginning of the CR/EQ sequences), so it's unlikely to cause any state change in the sink. As a side-note, this Novatek panel also lacks support for TPS3, while claiming support for HBR2, which violates the DP Standard (the Standard mandating TPS3 for HBR2). Besides the Novatek panel (PSR 1), which this change fixes, I also verified the change on a Samsung (PSR 1) and an Analogix (PSR 2) eDP panel as well as on the Intel Barlow Ridge TBT hub. Note that in the drm-tip tree (targeting the v6.17 kernel version) the i915 and xe drivers keep DPCD probing enabled only for the panel known to require this (HP ZR24w), hence those drivers in drm-tip are not affected by the above problem.

2025-07-15PM: sleep: Update power.completion for all devices on errorsRafael J. Wysocki
After commit aa7a9275ab81 ("PM: sleep: Suspend async parents after suspending children"), the following scenario is possible: 1. Device A is async and it depends on device B that is sync. 2. Async suspend is scheduled for A before the processing of B is started. 3. A is waiting for B. 4. In the meantime, an unrelated device fails to suspend and returns an error. 5. The processing of B doesn't start at all and its power.completion is not updated. 6. A is still waiting for B when async_synchronize_full() is called. 7. Deadlock ensues. To prevent this from happening, update power.completion for all devices on errors in all suspend phases, but do not do it directly for devices that are already being processed or are waiting for the processing to start because in those cases it may be necessary to wait for the processing to actually complete before updating power.completion for the device.

2025-07-15PM: suspend: clean up redundant filesystems_freeze/thaw() handlingZihuan Zhang
The recently introduced support for freezing filesystems during system suspend included calls to filesystems_freeze() in both suspend_prepare() and enter_state(), as well as calls to filesystems_thaw() in both suspend_finish() and the Unlock path in enter_state(). These are redundant. Moreover, calling filesystems_freeze() twice, from both suspend_prepare() and enter_state(), leads to a black screen and makes the system unable to resume in some cases. Address this as follows: - filesystems_freeze() is already called in suspend_prepare(), which is the proper and consistent place to handle pre-suspend operations. The second call in enter_state() is unnecessary and so remove it. - filesystems_thaw() is invoked in suspend_finish(), which covers successful suspend/resume paths. In the failure case, add a call to filesystems_thaw() only when needed, avoiding the duplicate call in the general Unlock path. This change simplifies the suspend code and avoids repeated freeze/thaw calls, while preserving correct ordering and behavior.

The pm_restore_gfp_mask() call added by commit 12ffc3b1513e ("PM: Restrict swap use to later in the suspend sequence") to suspend_devices_and_enter() is done too early because it takes place before calling dpm_resume() in dpm_resume_end() and some swap-backing devices may not be ready at that point. Moreover, dpm_resume_end() called subsequently in the same code path invokes pm_restore_gfp_mask() again and calling it twice in a row is pointless.

2025-07-15can: tcan4x5x: fix reset gpio usage during probeBrett Werling
Fixes reset GPIO usage during probe by ensuring we retrieve the GPIO and take the device out of reset (if it defaults to being in reset) before we attempt to communicate with the device. This is achieved by moving the call to tcan4x5x_get_gpios() before tcan4x5x_find_version() and avoiding any device communication while getting the GPIOs. Once we determine the version, we can then take the knowledge of which GPIOs we obtained and use it to decide whether we need to disable the wake or state pin functions within the device. This change is necessary in a situation where the reset GPIO is pulled high externally before the CPU takes control of it, meaning we need to explicitly bring the device out of reset before we can start communicating with it at all. This also has the effect of fixing an issue where a reset of the device would occur after having called tcan4x5x_disable_wake(), making the original behavior not actually disable the wake. This patch should now disable wake or state pin functions well after the reset occurs.

2025-07-15wifi: cfg80211: remove scan request n_channels counted_byJohannes Berg
This reverts commit e3eac9f32ec0 ("wifi: cfg80211: Annotate struct cfg80211_scan_request with __counted_by"). This really has been a completely failed experiment. There were no actual bugs found, and yet at this point we already have four "fixes" to it, with nothing to show for but code churn, and it never even made the code any safer. In all of the cases that ended up getting "fixed", the structure is also internally inconsistent after the n_channels setting as the channel list isn't actually filled yet. You cannot scan with such a structure, that's just wrong. In mac80211, the struct is also reused multiple times, so initializing it once is no good. Some previous "fixes" (e.g. one in brcm80211) are also just setting n_channels before accessing the array, under the assumption that the code is correct and the array can be accessed, further showing that the whole thing is just pointless when the allocation count and use count are not separate. If we really wanted to fix it, we'd need to separately track the number of channels allocated and the number of channels currently used, but given that no bugs were found despite the numerous syzbot reports, that'd just be a waste of time. Remove the __counted_by() annotation. We really should also remove a number of the n_channels settings that are setting up a structure that's inconsistent, but that can wait.

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. Generic PHYs do not support LEDs anyway, so don't bother registering them.

parents As described in a previous commit [1], Lion's patch [2] revealed an ancient bug in the qdisc API. Whenever a user tries to add a qdisc to an invalid parent (not a class, root, or ingress qdisc), the qdisc API will detect this after qdisc_create is called. Some qdiscs (like fq_codel, pie, and sfq) call functions (on their init callback) which assume the parent is valid, so qdisc_create itself may have caused a NULL pointer dereference in such cases. This commit creates 3 TDC tests that attempt to add fq_codel, pie and sfq qdiscs to invalid parents - Attempts to add an fq_codel qdisc to an hhf qdisc parent - Attempts to add a pie qdisc to a drr qdisc parent - Attempts to add an sfq qdisc to an inexistent hfsc classid (which would belong to a valid hfsc qdisc) [1] https://lore.kernel.org/all/20250707210801.372995-1-victor@mojatatu.com/ [2] https://lore.kernel.org/netdev/d912cbd7-193b-4269-9857-525bee8bbb6a@gmail.com/ Signed-off-by: Victor Nogueira <victor@mojatatu.com> Link: https://patch.msgid.link/20250712145035.705156-1-victor@mojatatu.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2025-07-14smc: Fix various oops due to inet_sock type confusion.Kuniyuki Iwashima
syzbot reported weird splats [0][1] in cipso_v4_sock_setattr() while freeing inet_sk(sk)->inet_opt. The address was freed multiple times even though it was read-only memory. cipso_v4_sock_setattr() did nothing wrong, and the root cause was type confusion. The cited commit made it possible to create smc_sock as an INET socket. The issue is that struct smc_sock does not have struct inet_sock as the first member but hijacks AF_INET and AF_INET6 sk_family, which confuses various places. In this case, inet_sock.inet_opt was actually smc_sock.clcsk_data_ready(), which is an address of a function in the text segment. $ pahole -C inet_sock vmlinux struct inet_sock { ... struct ip_options_rcu * inet_opt; /* 784 8 */ $ pahole -C smc_sock vmlinux struct smc_sock { ... void (*clcsk_data_ready)(struct sock *); /* 784 8 */ The same issue for another field was reported before. [2][3] At that time, an ugly hack was suggested [4], but it makes both INET and SMC code error-prone and hard to change. Also, yet another variant was fixed by a hacky commit 98d4435efcbf3 ("net/smc: prevent NULL pointer dereference in txopt_get"). Instead of papering over the root cause by such hacks, we should not allow non-INET socket to reuse the INET infra. Let's add inet_sock as the first member of smc_sock.

2025-07-14drm/panfrost: Fix scheduler workqueue bugPhilipp Stanner
When the GPU scheduler was ported to using a struct for its initialization parameters, it was overlooked that panfrost creates a distinct workqueue for timeout handling. The pointer to this new workqueue is not initialized to the struct, resulting in NULL being passed to the scheduler, which then uses the system_wq for timeout handling. Set the correct workqueue to the init args struct.

Its a kernel implementation detail, at least at this time: We can later decide to revert this patch if there is a compelling reason, but then we should also remove the ifdef that prevents exposure of ip_conntrack_status enum IPS_NAT_CLASH value in the uapi header. Clash entries are not included in dumps (true for both old /proc and ctnetlink) either. So for now exclude the clash bit when dumping.

Add a dedicated test to exercise conntrack clash resolution path. Test program emits 128 identical udp packets in parallel, then reads back replies from socat echo server. Also check (via conntrack -S) that the clash path was hit at least once. Due to the racy nature of the test its possible that despite the threaded program all packets were processed in-order or on same cpu, emit a SKIP warning in this case. Two tests are added: - one to test the simpler, non-nat case - one to exercise clash resolution where packets might have different nat transformations attached to them.

The Lenovo Yoga Book 9i GenX has the wrong values in the cirrus,dev-index _DSD property. Add a fixup for this model to ignore the property and hardcode the index from the I2C bus address. The error in the cirrus,dev-index property would prevent the second amp instance from probing. The component binding would never see all the required instances and so there would not be a binding between patch_realtek.c and the cs35l56 driver.

2025-07-14cpuidle: psci: Fix cpuhotplug routine with PREEMPT_RT=yDaniel Lezcano
Currently cpu hotplug with the PREEMPT_RT option set in the kernel is not supported because the underlying generic power domain functions used in the cpu hotplug callbacks are incompatible from a lock point of view. This situation prevents the suspend to idle to reach the deepest idle state for the "cluster" as identified in the undermentioned commit. Use the compatible ones when PREEMPT_RT is enabled and remove the boolean disabling the hotplug callbacks with this option. With this change the platform can reach the deepest idle state allowing at suspend time to consume less power.

2025-07-13ASoC: Intel: fix SND_SOC_SOF dependenciesArnd Bergmann
It is currently possible to configure a kernel with all Intel SoC configs as loadable modules, but the board config as built-in. This causes a link failure in the reference to the snd_soc_sof.ko module: x86_64-linux-ld: sound/soc/intel/boards/sof_rt5682.o: in function `sof_rt5682_hw_params': sof_rt5682.c:(.text+0x1f9): undefined reference to `sof_dai_get_mclk' x86_64-linux-ld: sof_rt5682.c:(.text+0x234): undefined reference to `sof_dai_get_bclk' x86_64-linux-ld: sound/soc/intel/boards/sof_rt5682.o: in function `sof_rt5682_codec_init': sof_rt5682.c:(.text+0x3e0): undefined reference to `sof_dai_get_mclk' x86_64-linux-ld: sound/soc/intel/boards/sof_cs42l42.o: in function `sof_cs42l42_hw_params': sof_cs42l42.c:(.text+0x2a): undefined reference to `sof_dai_get_bclk' x86_64-linux-ld: sound/soc/intel/boards/sof_nau8825.o: in function `sof_nau8825_hw_params': sof_nau8825.c:(.text+0x7f): undefined reference to `sof_dai_get_bclk' x86_64-linux-ld: sound/soc/intel/boards/sof_da7219.o: in function `da7219_codec_init': sof_da7219.c:(.text+0xbf): undefined reference to `sof_dai_get_mclk' x86_64-linux-ld: sound/soc/intel/boards/sof_maxim_common.o: in function `max_98373_hw_params': sof_maxim_common.c:(.text+0x6f9): undefined reference to `sof_dai_get_tdm_slots' x86_64-linux-ld: sound/soc/intel/boards/sof_realtek_common.o: in function `rt1015_hw_params': sof_realtek_common.c:(.text+0x54c): undefined reference to `sof_dai_get_bclk' x86_64-linux-ld: sound/soc/intel/boards/sof_realtek_common.o: in function `rt1308_hw_params': sof_realtek_common.c:(.text+0x702): undefined reference to `sof_dai_get_mclk' x86_64-linux-ld: sound/soc/intel/boards/sof_cirrus_common.o: in function `cs35l41_hw_params': sof_cirrus_common.c:(.text+0x2f): undefined reference to `sof_dai_get_bclk' Add an optional dependency on SND_SOC_SOF_INTEL_COMMON, to ensure that whenever the SOF support is in a loadable module, none of the board code can be built-in. This may be be a little heavy-handed, but I also don't see a reason why one would want the boards to be built-in but not the SoC, so it shouldn't actually cause any usability problems.
