2017-06-07ALSA: timer: Fix missing queue indices reset at SNDRV_TIMER_IOCTL_SELECTTakashi Iwai1-0/+1
snd_timer_user_tselect() reallocates the queue buffer dynamically, but it forgot to reset its indices. Since the read may happen concurrently with ioctl and snd_timer_user_tselect() allocates the buffer via kmalloc(), this may lead to the leak of uninitialized kernel-space data, as spotted via KMSAN: BUG: KMSAN: use of unitialized memory in snd_timer_user_read+0x6c4/0xa10 CPU: 0 PID: 1037 Comm: probe Not tainted 4.11.0-rc5+ #2739 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Bochs 01/01/2011 Call Trace: __dump_stack lib/dump_stack.c:16 dump_stack+0x143/0x1b0 lib/dump_stack.c:52 kmsan_report+0x12a/0x180 mm/kmsan/kmsan.c:1007 kmsan_check_memory+0xc2/0x140 mm/kmsan/kmsan.c:1086 copy_to_user ./arch/x86/include/asm/uaccess.h:725 snd_timer_user_read+0x6c4/0xa10 sound/core/timer.c:2004 do_loop_readv_writev fs/read_write.c:716 __do_readv_writev+0x94c/0x1380 fs/read_write.c:864 do_readv_writev fs/read_write.c:894 vfs_readv fs/read_write.c:908 do_readv+0x52a/0x5d0 fs/read_write.c:934 SYSC_readv+0xb6/0xd0 fs/read_write.c:1021 SyS_readv+0x87/0xb0 fs/read_write.c:1018 This patch adds the missing reset of queue indices.

2017-06-07ALSA: timer: Fix race between read and ioctlTakashi Iwai1-2/+4
The read from ALSA timer device, the function snd_timer_user_tread(), may access to an uninitialized struct snd_timer_user fields when the read is concurrently performed while the ioctl like snd_timer_user_tselect() is invoked. We have already fixed the races among ioctls via a mutex, but we seem to have forgotten the race between read vs ioctl. This patch simply applies (more exactly extends the already applied range of) tu->ioctl_lock in snd_timer_user_tread() for closing the race window.

The previous commit [63691587f7b0: ALSA: hda - Apply dual-codec quirk for MSI Z270-Gaming mobo] attempted to apply the existing dual-codec quirk for a MSI mobo. But it turned out that this isn't applied properly due to the MSI-vendor quirk before this entry. I overlooked such two MSI entries just because they were put in the wrong position, although we have a list ordered by PCI SSID numbers. This patch fixes it by rearranging the unordered entries.

This reverts commit 89b593c30e83 ("ALSA: usb-audio: purge needless variable length array"). The patch turned out to cause a severe regression, triggering an Oops at snd_usb_ctl_msg(). It was overseen that snd_usb_ctl_msg() writes back the response to the given buffer, while the patch changed it to a read-only const buffer. (One should always double-check when an extra pointer cast is present...) As a simple fix, just revert the affected commit. It was merely a cleanup. Although it brings VLA again, it's clearer as a fix. We'll address the VLA later in another patch.

In SKL+ platforms, all IPC commands are serialised, i.e. the driver sends a new IPC to DSP, only after receiving a reply from the firmware for the current IPC. Hence it seems apparent that there is only a single modifier of the IPC RX List. However, during an IPC timeout case in a multithreaded environment, there is a possibility of the list element being deleted two times if not properly protected.

2017-05-24ASoC: Fix use-after-free at card unregistrationTakashi Iwai1-2/+3
soc_cleanup_card_resources() call snd_card_free() at the last of its procedure. This turned out to lead to a use-after-free. PCM runtimes have been already removed via soc_remove_pcm_runtimes(), while it's dereferenced later in soc_pcm_free() called via snd_card_free(). The fix is simple: just move the snd_card_free() call to the beginning of the whole procedure. This also gives another benefit: it guarantees that all operations have been shut down before actually releasing the resources, which was racy until now.

2017-05-15drm/i915: Fix runtime PM for LPE audioVille Syrjälä1-4/+0
Not calling pm_runtime_enable() means that runtime PM can't be enabled at all via sysfs. So we definitely need to call it from somewhere. Calling it from the driver seems like a bad idea because it would have to be paired with a pm_runtime_disable() at driver unload time, otherwise the core gets upset. Also if there's no LPE audio driver loaded then we couldn't runtime suspend i915 either. So it looks like a better plan is to call it from i915 when we register the platform device. That seems to match how pci generally does things. I cargo culted the pm_runtime_forbid() and pm_runtime_set_active() calls from pci as well. The exposed runtime PM API is massive an thorougly misleading, so I don't actually know if this is how you're supposed to use the API or not. But it seems to work. I can now runtime suspend i915 again with or without the LPE audio driver loaded, and reloading the LPE audio driver also seems to work. Note that powertop won't auto-tune runtime PM for platform devices, which is a little annoying. So I'm not sure that leaving runtime PM in "on" mode by default is the best choice here. But I've left it like that for now at least. Also remove the comment about there not being much benefit from LPE audio runtime PM. Not allowing runtime PM blocks i915 runtime PM, which will also block s0ix, and that could have a measurable impact on power consumption.

2017-05-14rt286: add Thinkpad Helix 2 to force_combo_jack_tableYifeng Li1-0/+7
Thinkpad Helix 2 is a tablet PC, the audio is powered by Core M broadwell-audio and rt286 codec. For all versions of Linux kernel, the stereo output doesn't work properly when earphones are plugged in, the sound was coming out from both channels even if the audio contains only the left or right channel. Furthermore, if a music recorded in stereo is played, the two channels cancle out each other out, as a result, no voice but only distorted background music can be heard, like a sound card with builtin a Karaoke sount effect. Apparently this tablet uses a combo jack with polarity incorrectly set by rt286 driver. This patch adds DMI information of Thinkpad Helix 2 to force_combo_jack_table[] and the issue is resolved. The microphone input doesn't work regardless to the presence of this patch and still needs help from other developers to investigate.

OSS drivers are left as badly unmaintained, and now we're facing a problem to clean up the hackish set_fs() usage in their codes. Since most of drivers have been covered by ALSA, and the others are dead old and inactive, let's leave them RIP. This patch is the first step: disable the build of OSS drivers. We'll eventually drop the whole codes and clean up later. Note that sound/oss/dmasound is still kept, since it's a completely different implementation of OSS, and it doesn't suffer from set_fs() hack. Moreover, the build of ALSA is disabled on M68K by some reason, thus disabling it shall result in a regression. This one will be disabled / removed once when we add the support in ALSA side.

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs Pull hw lockdown support from David Howells: "Annotation of module parameters that configure hardware resources including ioports, iomem addresses, irq lines and dma channels. This allows a future patch to prohibit the use of such module parameters to prevent that hardware from being abused to gain access to the running kernel image as part of locking the kernel down under UEFI secure boot conditions. Annotations are made by changing: module_param(n, t, p) module_param_named(n, v, t, p) module_param_array(n, t, m, p) to: module_param_hw(n, t, hwtype, p) module_param_hw_named(n, v, t, hwtype, p) module_param_hw_array(n, t, hwtype, m, p) where the module parameter refers to a hardware setting hwtype specifies the type of the resource being configured. This can be one of: ioport Module parameter configures an I/O port iomem Module parameter configures an I/O mem address ioport_or_iomem Module parameter could be either (runtime set) irq Module parameter configures an I/O port dma Module parameter configures a DMA channel dma_addr Module parameter configures a DMA buffer address other Module parameter configures some other value Note that the hwtype is compile checked, but not currently stored (the lockdown code probably won't require it). It is, however, there for future use. A bonus is that the hwtype can also be used for grepping. The intention is for the kernel to ignore or reject attempts to set annotated module parameters if lockdown is enabled. This applies to options passed on the boot command line, passed to insmod/modprobe or direct twiddling in /sys/module/ parameter files. The module initialisation then needs to handle the parameter not being set, by (1) giving an error, (2) probing for a value or (3) using a reasonable default. What I can't do is just reject a module out of hand because it may take a hardware setting in the module parameters. Some important modules, some ipmi stuff for instance, both probe for hardware and allow hardware to be manually specified; if the driver is aborts with any error, you don't get any ipmi hardware. Further, trying to do this entirely in the module initialisation code doesn't protect against sysfs twiddling. [!] Note that in and of itself, this series of patches should have no effect on the the size of the kernel or code execution - that is left to a patch in the next series to effect.
