[Sound-open-firmware] [PATCH AUTOSEL 5.17 09/21] ASoC: SOF: Fix NULL pointer exception in sof_pci_probe callback

[Sound-open-firmware] tracking work to move SOF app code to Zephyr native interfaces
by Kai Vehmanen 10 May '22

10 May '22

Hi, it's been possible for a while to build SOF both with Zephyr [1] and with the in-tree XTOS version. We started off by wrapping app calls to OS services into calls to Zephyr. Recently, we've started taking the next steps and started replacing the main code to use native Zephyr interfaces where appropriate, and wrap the calls into XTOS when building with the latter. Intent is to keep both builds functional at all times. Due to the incremental nature, this can be hard to track and understand at times, so I filed today a meta issue to track all ongoing work: - https://github.com/thesofproject/sof/issues/5794 [1] https://thesofproject.github.io/latest/getting_started/build-guide/build-wi… Br, Kai

[Sound-open-firmware] [bug report] ASoC: SOF: Intel: hda: Revisit IMR boot sequence
by Dan Carpenter 27 Apr '22

27 Apr '22

Hello Peter Ujfalusi, The patch 2a68ff846164: "ASoC: SOF: Intel: hda: Revisit IMR boot sequence" from Apr 21, 2022, leads to the following Smatch static checker warning: sound/soc/sof/intel/hda-loader.c:397 hda_dsp_cl_boot_firmware() info: return a literal instead of 'ret' sound/soc/sof/intel/hda-loader.c 381 int hda_dsp_cl_boot_firmware(struct snd_sof_dev *sdev) 382 { 383 struct sof_intel_hda_dev *hda = sdev->pdata->hw_pdata; 384 struct snd_sof_pdata *plat_data = sdev->pdata; 385 const struct sof_dev_desc *desc = plat_data->desc; 386 const struct sof_intel_dsp_desc *chip_info; 387 struct hdac_ext_stream *hext_stream; 388 struct firmware stripped_firmware; 389 struct snd_dma_buffer dmab; 390 int ret, ret1, i; 391 392 if (hda->imrboot_supported && !sdev->first_boot) { 393 dev_dbg(sdev->dev, "IMR restore supported, booting from IMR directly\n"); 394 hda->boot_iteration = 0; 395 ret = hda_dsp_boot_imr(sdev); 396 if (ret >= 0) --> 397 return ret; The hda_dsp_boot_imr() has some similar stuff where it checks for positive returns. As far as I can see, this code never returns positive values. Normally kernel code returns zero on success and negative error codes on failure. When code returns non-standard things then it really should be documented what the positive returns mean. Nothing complicated, just add a comment at the start of the function. The TLDR back story of this Smatch check is that it's not published but it regularly finds bugs. The issue is that it's more readable, plus it looks more deliberate and intentional to write: if (!ret) return 0; instead of: if (!ret) return ret; With the latter format, the bug is that people intended to write: if (ret) return ret; Obviously this kind of bug would get caught in testing, but testing is often impossible in the kernel because it depends on hardware availability. 398 399 dev_warn(sdev->dev, "IMR restore failed, trying to cold boot\n"); 400 } 401 402 chip_info = desc->chip_info; 403 regards, dan carpenter

[Sound-open-firmware] out-of-bounds access in sound/soc/sof/topology.c
by Sergey Senozhatsky 27 Apr '22

27 Apr '22

Hi, I'm running 5.10.111 LTS, so if this has been fixed already then we definitely want to cherry pick the fix for -stable. Anonymous union in this struct is of zero size /* generic control data */ struct sof_ipc_ctrl_data { struct sof_ipc_reply rhdr; uint32_t comp_id; /* control access and data type */ uint32_t type; /**< enum sof_ipc_ctrl_type */ uint32_t cmd; /**< enum sof_ipc_ctrl_cmd */ uint32_t index; /**< control index for comps > 1 control */ /* control data - can either be appended or DMAed from host */ struct sof_ipc_host_buffer buffer; uint32_t num_elems; /**< in array elems or bytes for data type */ uint32_t elems_remaining; /**< elems remaining if sent in parts */ uint32_t msg_index; /**< for large messages sent in parts */ /* reserved for future use */ uint32_t reserved[6]; /* control data - add new types if needed */ union { /* channel values can be used by volume type controls */ struct sof_ipc_ctrl_value_chan chanv[0]; /* component values used by routing controls like mux, mixer */ struct sof_ipc_ctrl_value_comp compv[0]; /* data can be used by binary controls */ struct sof_abi_hdr data[0]; }; } __packed; sof_ipc_ctrl_value_chan and sof_ipc_ctrl_value_comp are of the same size - 8 bytes, while sof_abi_hdr is much larger - _at least_ 32 bytes (`__u32 data[0]` in sof_abi_hdr suggest that there should be more payload after header). But they all contribute 0 to sizeof(sof_ipc_ctrl_data). Now control data allocations looks as follows scontrol->size = struct_size(scontrol->control_data, chanv, le32_to_cpu(mc->num_channels)); scontrol->control_data = kzalloc(scontrol->size, GFP_KERNEL); Which is sizeof(sof_ipc_ctrl_data) + mc->num_channels * sizeof(sof_ipc_ctrl_value_chan) For some reason it uses sizeof(sof_ipc_ctrl_value_chan), which is not the largest member of the union. And this is where the problem is: in order to make control->data.FOO loads and stores legal we need mc->num_channels to be of at least 4. So that sizeof(sof_ipc_ctrl_data) + mc->num_channels * sizeof(sof_ipc_ctrl_value_chan) 92 + 4 * 8 will be the same as sizeof(sof_ipc_ctrl_data) + sizeof(sof_abi_hdr). 92 + 32 Otherwise scontrol->control_data->data.FOO will access nearby/foreign slab object. And there is at least one such memory access. In sof_get_control_data(). wdata[i].pdata = wdata[i].control->control_data->data; *size += wdata[i].pdata->size; pdata->size is at offset 8, but if, say, mc->num_channels == 1 then we allocate only 8 bytes for pdata, so pdata->size is 4 bytes outside of allocated slab object. Thoughts?

[Sound-open-firmware] [PATCH] ASoC: SOF: using pm_runtime_resume_and_get to simplify the code
by cgel.zte＠gmail.com 21 Apr '22

[1/1] ASoC: SOF: Kconfig: Make SND_SOC_SOF_HDA_PROBES tristate commit: e18610eaa66a1849aaa00ca43d605fb1a6fed800 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark
