Kernel: Linux 6.12.73+deb13-amd64 (SMP w/4 CPU threads; PREEMPT) Kernel taint flags: TAINT_WARN Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to de_DE.UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Package: src:linux Version: 6.12.73-1 Severity: important Hi, on Debian trixie with kernel 6.12.73+deb13-amd64 I get repeated kernel WARNINGs from the Intel wireless driver (iwlwifi/iwlmvm) when running hostapd in AP mode. The system continues running, but the kernel is tainted with 'G W' and the call trace points into _iwl_mvm_sec_key_del() in mld-key.c while keys are being removed. System information ------------------ - Distribution: Debian trixie (testing) - Kernel: 6.12.73+deb13-amd64 #1 Debian 6.12.73-1 - Machine: ASRock H470M-STX, BIOS P2.20 08/06/2021 - Wireless hardware (from lspci -nn): 00:14.3 Network controller [0280]: Intel Corporation Comet Lake PCH CNVi WiFi [8086:06f0] - Ethernet: Intel Corporation Ethernet Connection (11) I219-V [8086:0d4d] - hostapd version: 2:2.10-24 - hostapd.conf: interface=wlo1 driver=nl80211 hw_mode=g bridge=br0 auth_algs=1 wpa=2 channel=4 wmm_enabled=1 country_code=DE ieee80211d=1 ieee80211n=1 ieee80211ac=1 ssid=<ssid> ignore_broadcast_ssid=0 wpa_passphrase=<pw> wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP rsn_pairwise=CCMP Steps to reproduce ------------------ 1. Boot Debian trixie with kernel 6.12.73+deb13-amd64 on this hardware. 2. Use the Intel CNVi WiFi adapter in AP mode with hostapd. - Interface: <wlanX> (created by iwlwifi) - Mode: AP (bridged to LAN), WPA2/WPA3 PSK (details available on request). 3. Start and use the AP normally (clients connect and disconnect). 4. Stop or restart the wireless interface / hostapd (e.g. via ifdown/ifup, systemd service restart, or changing IP/interface flags). After some time and/or during shutdown of the interface, kernel WARNINGs appear in dmesg. Expected result --------------- - No kernel WARNING/OOPS when using the Intel CNVi WiFi adapter in AP mode with hostapd. - Keys should be added and removed cleanly without tainting the kernel. Actual result ------------- - The kernel logs a WARNING in _iwl_mvm_sec_key_del() from the iwlmvm module when keys are being removed or replaced, for example when stopping the interface. - The kernel is tainted with 'G W', but the system does not panic and continues to run. Example kernel log ------------------ Below are two of the WARNings as printed in dmesg: [73024.998029] iwlwifi 0000:00:14.3 wlo1: left allmulticast mode [73024.998036] iwlwifi 0000:00:14.3 wlo1: left promiscuous mode [73024.998052] br0: port 2(wlo1) entered disabled state [73025.001385] br0: port 1(eno2) entered disabled state [73025.043637] ------------[ cut here ]------------ [73025.043641] WARNING: CPU: 0 PID: 25626 at drivers/net/wireless/intel/iwlwifi/mvm/mld-key.c:307 _iwl_mvm_sec_key_del+0x166/0x180 [iwlmvm] [73025.043672] Modules linked in: uas usb_storage ccm bridge stp llc nf_tables libcrc32c dm_crypt dm_mod snd_seq_dummy snd_hrtimer snd_seq snd_seq_device rfcomm cmac algif_hash algif_skcipher af_alg bnep binfmt_misc nls_ascii nls_cp437 vfat fat snd_sof_pci_intel_cnl snd_sof_intel_hda_generic soundwire_intel soundwire_generic_allocation soundwire_cadence snd_sof_intel_hda_common snd_soc_hdac_hda snd_sof_intel_hda_mlink snd_sof_intel_hda snd_sof_pci snd_sof_xtensa_dsp snd_sof intel_rapl_msr snd_hda_codec_hdmi intel_rapl_common intel_uncore_frequency snd_sof_utils intel_uncore_frequency_common iwlmvm snd_soc_acpi_intel_match snd_soc_acpi soundwire_bus snd_hda_codec_realtek snd_soc_avs mac80211 snd_soc_hda_codec snd_hda_codec_generic snd_hda_ext_core snd_hda_scodec_component snd_soc_core x86_pkg_temp_thermal intel_powerclamp coretemp snd_compress kvm_intel snd_pcm_dmaengine snd_hda_intel btusb snd_intel_dspcfg snd_intel_sdw_acpi libarc4 snd_hda_codec btrtl kvm iwlwifi btintel snd_hda_core btbcm btmtk snd_hwdep snd_pcm [73025.043721] irqbypass radio_ma901 bluetooth cfg80211 mei_pxp mei_hdcp rapl snd_timer intel_cstate videodev snd ftdi_sio intel_uncore usbserial ecdh_generic mei_me soundcore mc ee1004 wmi_bmof pcspkr mei rfkill intel_pch_thermal intel_pmc_core joydev intel_vsec acpi_tad acpi_pad pmt_telemetry pmt_class sg evdev parport_pc ppdev lp parport efi_pstore configfs nfnetlink efivarfs ip_tables x_tables autofs4 ext4 crc16 mbcache jbd2 crc32c_generic i915 hid_generic usbhid hid sd_mod drm_buddy i2c_algo_bit drm_display_helper cec crct10dif_pclmul rc_core crc32_pclmul crc32c_intel ttm ghash_clmulni_intel sha512_ssse3 drm_kms_helper sha256_ssse3 iTCO_wdt xhci_pci sha1_ssse3 intel_pmc_bxt xhci_hcd aesni_intel ahci iTCO_vendor_support drm libahci watchdog gf128mul libata e1000e crypto_simd i2c_i801 usbcore cryptd scsi_mod i2c_smbus scsi_common usb_common video wmi button [73025.043782] CPU: 0 UID: 0 PID: 25626 Comm: hostapd Tainted: G W 6.12.73+deb13-amd64 #1 Debian 6.12.73-1 [73025.043786] Tainted: [W]=WARN [73025.043787] Hardware name: To Be Filled By O.E.M.
