[Fix] For backport-iwlwifi-dkms, in the master branch HEAD it has commit 5a3d01a7ea635 ("[BUGFIX] wifi: iwlwifi: mvm: avoid oversized UATS command copy"), which is incomplete that Intel gives an additional patch titled "wifi: iwlwifi: mvm: don't map the stack to DMA". These two patches combined equal to https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi- next.git/commit/?h=fixes&id=e0c121d545134af886b28c4c26d91abf5dd39c17 ("wifi: iwlwifi: mvm: avoid oversized UATS command copy"). However the later breaks builds against kernel < 7.0 and therefore it takes additional backport related to kmalloc_obj family from commit 4862faa9c3dd ("Merge remote-tracking branch 'auto/master'"). Later, it's found to cause another PHC register failure warning on kernels >= 7.0, and it takes backports related to settime64 from another commit 5076fafb8e33 ("Merge remote-tracking branch 'auto/master'"). For the linux kernel in-tree iwlwifi driver, Intel proposed a fix https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi- next.git/commit/?h=fixes&id=e0c121d545134af886b28c4c26d91abf5dd39c17 ("wifi: iwlwifi: mvm: avoid oversized UATS command copy") that is already in linux-next. While v7.0 has already commit 81d90d93d22ca ("wifi: iwlwifi: Implement settime64 as stub for MVM/MLD PTP") that fixes the PHC register problem, no additional fix is needed. [Test Plan] There are 4 cases: * linux-unstable-7.1/stonking * linux-generic-7.0/resolute * linux-oem-7.0/resolute * backport-iwlwifi-dkms/stoking - tested against linux-unstable-7.1/stonking * backport-iwlwifi-dkms/resolute - tested against linux-generic-7.0/resolute, linux-oem-7.0/resolute and linux-oem-6.17/noble To test kernel packages: 1. Install kernels from corresponding -proposed pocket. 2. Boot from some Intel Wildcat Lake platforms with an Intel AX211 wireless module installed. Here I use Intel WCL-U RVP. 3. The dmesg should gives no error but probe iwlwifi kernel module successfully. To test backport-iwlwifi-dkms packages: 1. Boot the testing kernel from some Intel Wildcat Lake platforms with an Intel AX211 wireless module installed. Here I use Intel WCL-U RVP. 2. Install kernels from corresponding -proposed pocket. 3. The corresponding kernel modules should be built automatically by dpkg triggers. Use `dkms status` to list built kernel versions. 4. Reboot into the same kernel. The dmesg should gives no error but probe iwlwifi kernel module successfully. [Where problems could occur] This changes the way that command object is handled using IWL_HCMD_DFL_NOCOPY to avoid buffer size checking. It doesn't really change runtime behavior or anything else. [Other Info] The patches for backport-iwlwifi-dkms are meant to be superseded by the ones in the master branch, so I did not cherry-pick the one from linux-next instead. Nominate backport-iwlwifi-dkms Resolute and Stonking, because they are versions with WCL support. Nominate linux/{Q,R}, linux-oem-7.0, linux-oem-6.17, because they are either 7.0 kernels or uses backport-iwlwifi-dkms/R. ========== original bug report ========== May 04 13:33:52 ubuntu-202603-38491 kernel: ------------[ cut here ]------------ May 04 13:33:52 ubuntu-202603-38491 kernel: Command UNKNOWN (0xc05) is too large (348 bytes) May 04 13:33:52 ubuntu-202603-38491 kernel: WARNING: CPU: 4 PID: 995 at drivers/net/wireless/intel/iwlwifi/pcie/gen1_2/tx-gen2.c:1278 iwl_pcie_gen2_enqueue_hcmd+0x7ea/0xf10 [iwlwifi] May 04 13:33:52 ubuntu-202603-38491 kernel: Modules linked in: snd_soc_sof_sdw snd_sof_probes snd_soc_intel_hda_dsp_common qrtr snd_soc_rt722_sdca regmap_sdw_mbq snd_hda_codec_intelhdmi snd_soc_dmic bnep snd_hda_intel snd_sof_pci_intel_ptl snd_sof_pci_intel_lnl snd_sof_pci_intel_mtl snd_sof_intel_hda_generic soundwire_intel snd_sof_intel_hda_sdw_bpt snd_sof_intel_hda_common snd_soc_hdac_hda snd_sof_intel_hda_mlink snd_sof_intel_hda snd_hda_codec_hdmi soundwire_cadence snd_sof_pci snd_sof_xtensa_dsp snd_sof snd_sof_utils snd_hda_ext_core snd_hda_codec snd_hda_core snd_intel_dspcfg snd_intel_sdw_acpi snd_soc_acpi_intel_match snd_soc_acpi_intel_sdca_quirks soundwire_generic_allocation snd_soc_sdw_utils snd_soc_acpi snd_hwdep intel_uncore_frequency soundwire_bus intel_uncore_frequency_common snd_soc_sdca x86_pkg_temp_thermal snd_soc_core intel_powerclamp snd_compress coretemp ac97_bus snd_pcm_dmaengine snd_pcm kvm_intel snd_seq_midi dell_pc snd_ctl_led snd_seq_midi_event mei_gsc_proxy intel_rapl_msr binfmt_misc snd_rawmidi kvm xe uvcvideo dell_laptop May 04 13:33:52 ubuntu-202603-38491 kernel: snd_seq irqbypass videobuf2_vmalloc iwlmvm(O) uvc gpu_sched processor_thermal_device_pci videobuf2_memops polyval_clmulni btusb drm_gpuvm ghash_clmulni_intel videobuf2_v4l2 processor_thermal_device btrtl processor_thermal_wt_hint videobuf2_common aesni_intel dell_wmi drm_gpusvm_helper snd_seq_device platform_temperature_control mac80211(O) btintel drm_buddy dell_smbios snd_timer drm_ttm_helper processor_thermal_soc_slider btbcm videodev processor_thermal_rfim ttm btmtk dcdbas nls_iso8859_1 bluetooth libarc4 dell_wmi_ddv dell_wmi_sysman(+) dell_smm_hwmon mc firmware_attributes_class drm_exec iwlwifi(O) processor_thermal_rapl snd intel_rapl_common i2c_i801 processor_thermal_wt_req drm_suballoc_helper dell_wmi_descriptor wmi_bmof i2c_smbus processor_thermal_power_floor soundcore mei_me drm_display_helper processor_thermal_mbox crc8 i2c_mux mei cfg80211(O) cec intel_vpu rc_core iwlwifi_compat(O) intel_pmc_core platform_profile i2c_algo_bit igen6_edac pmt_telemetry int3403_thermal int340x_thermal_zone May 04 13:33:52 ubuntu-202603-38491 kernel: pmt_discovery pmt_class int3400_thermal intel_pmc_ssram_telemetry acpi_thermal_rel intel_vsec acpi_tad intel_hid sparse_keymap acpi_pad joydev input_leds serio_raw mac_hid sch_fq_codel msr parport_pc ppdev lp parport nvme_fabrics efi_pstore nfnetlink dmi_sysfs ip_tables x_tables autofs4 raid10 raid456 async_raid6_recov async_memcpy async_pq async_xor async_tx xor raid6_pq raid1 raid0 linear uas usb_storage ucsi_acpi hid_multitouch typec_ucsi hid_generic typec nvme psmouse video intel_lpss_pci nvme_core e1000e nvme_keyring intel_lpss nvme_auth idma64 thunderbolt i2c_hid_acpi i2c_hid hid wmi pinctrl_intel_platform May 04 13:33:52 ubuntu-202603-38491 kernel: CPU: 4 UID: 0 PID: 995 Comm: NetworkManager Tainted: G O 6.17.0-1020-oem #20-Ubuntu PREEMPT(voluntary) May 04 13:33:52 ubuntu-202603-38491 kernel: Tainted: [O]=OOT_MODULE May 04 13:33:52 ubuntu-202603-38491 kernel: Hardware name: Dell Inc.
