[alsa-devel] [PATCH] [PATCH] ALSA: Remove deprecated AU1X00 AC97 driver
by Lars-Peter Clausen 08 Feb '16

08 Feb '16

The AU1X00 AC97 ALSA driver was deprecated in commit 7137c6bcb7ff ("ALSA: deprecate MIPS AU1X00 AC97 driver") in favor of the newer and better ASoC driver for the same hardware. This was almost 5 years ago and this driver has not been in use in the mainline kernel since, it should be safe to remove it at this point.

[alsa-devel] SGTL5000
by Erik Friesen 07 Feb '16

07 Feb '16

I was sort of directed to this list from linux-arm. I have been working with an embeddedarm ts4900 and built a baseboard that uses the sgtl5000. I also have worked with the RiotBoard, which uses the same chip, both using the i.mx6 arm. I find that occasionally the sgtl5000 is resetting, and there is no way to bring it back online. As near as I can tell, the i2c bus comes back alive, for example alsamixer communicates fine, coms happen on the i2c bus per scope. However, its obvious the chip never gets re initialized by how it acts. I know the thing shouldn't reset, that is the primary problem, but I still want some backup method. Its probably due to ground bounce from a non earth grounded setup. It could be that using the external regulator will help, we will see. Is there a suggestion on a way the sgtl5000.c could be extended to support some sort of re initialize routine? I am using the embeddedarm repo as a base kernel. sgtl5000.c has been updated to include ret = sgtl5000_fill_defaults(sgtl5000); but the base kernel is 3.10.53. However, the riotboard runs 4.3 with similar results.

[alsa-devel] About planning of libhinawa ITP to debian project
by Takashi Sakamoto 07 Feb '16

07 Feb '16

Hi, In this message, I explain about a plan of libhinawa ITP[0] to debian project. Fortunately, I got a help of a debian package maintainer, Kentaro Hayashi. He maintains groonga package[1] and experienced related works[2]. Currently, we plan to work for it in next month, February 2016. I have no idea about when FTP master acked to our ITP and when the package is released from debian project. I with the package will be available as early as possible, and this work will be a part of his great work as a debian package maintainer. FYI, [0] ITP = Intent To Packaging [1] Debian -- Details of package groonga in sid: https://packages.debian.org/sid/groonga [2] Debian Bug report logs - #732055 ITP: groonga -- Fulltext search engine https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=732055 Takashi Sakamoto

[alsa-devel] sound: heap out-of-bounds write in dummy_systimer_prepare
by Dmitry Vyukov 07 Feb '16

07 Feb '16

Hello, I am still seeing these eap out-of-bounds writes in dummy_systimer_prepare. Even when we've disabled the hrtimer sysctl. The fuzzer does not change sysctls at the moment and I think we've overlooked a very simple possibility that can happen when sysctls are not changed (i.e. triggered by an unprivileged user). dummy_pcm_open does: static int dummy_pcm_open(struct snd_pcm_substream *substream) { ... dummy->timer_ops = &dummy_systimer_ops; #ifdef CONFIG_HIGH_RES_TIMERS if (hrtimer) dummy->timer_ops = &dummy_hrtimer_ops; #endif There is a small window of time when we switch timer_ops to dummy_systimer_ops and then restore it back to dummy_hrtimer_ops. If another thread executes a timer op during that window, it happily smashes heap thinking that there is a systimer there. KTSAN, a data race detector (https://github.com/google/ktsan), would catch this in a blink of an eye and give a detailed explanation of what happens... ================================================================== [ 134.926046] BUG: KASAN: slab-out-of-bounds in dummy_systimer_prepare+0x268/0x2a0 at addr ffff880030f00b10 [ 134.926046] Write of size 4 by task syz-executor/32211 [ 134.926046] ============================================================================= [ 134.926046] BUG kmalloc-192 (Not tainted): kasan: bad access detected [ 134.926046] ----------------------------------------------------------------------------- [ 134.926046] [ 134.926046] INFO: Allocated in dummy_hrtimer_create+0x49/0x1a0 age=5 cpu=0 pid=32211 [ 134.926046] ___slab_alloc+0x564/0x5b0 [ 134.926046] __slab_alloc+0x66/0xc0 [ 134.926046] kmem_cache_alloc_trace+0x25c/0x300 [ 134.931676] dummy_hrtimer_create+0x49/0x1a0 [ 134.931676] dummy_pcm_open+0xef/0x570 [ 134.932135] snd_pcm_open_substream+0x188/0x430 [ 134.932135] snd_pcm_oss_open.part.17+0x5a4/0x1110 [ 134.932135] snd_pcm_oss_open+0x35/0x50 [ 134.932135] soundcore_open+0x30f/0x640 [ 134.932135] chrdev_open+0x22a/0x4c0 [ 134.932135] do_dentry_open+0x6a2/0xcb0 [ 134.932135] vfs_open+0x17b/0x1f0 [ 134.932135] path_openat+0xde9/0x5e30 [ 134.932135] do_filp_open+0x18e/0x250 [ 134.932135] do_sys_open+0x1fc/0x420 [ 134.932135] SyS_open+0x2d/0x40 [ 134.932135] INFO: Freed in snd_pcm_plugin_free+0xb1/0xe0 age=20 cpu=0 pid=32142 [ 134.932135] __slab_free+0x1fc/0x320 [ 134.932135] kfree+0x2ac/0x2c0 [ 134.932135] snd_pcm_plugin_free+0xb1/0xe0 [ 134.932135] snd_pcm_oss_release_substream+0x113/0x1f0 [ 134.932135] snd_pcm_release_substream.part.38+0x1e8/0x2f0 [ 134.937048] snd_pcm_release_substream+0x59/0x70 [ 134.937048] snd_pcm_oss_release_file+0x7b/0xb0 [ 134.937048] snd_pcm_oss_release+0xfa/0x280 [ 134.937048] __fput+0x236/0x780 [ 134.937048] ____fput+0x15/0x20 [ 134.937048] task_work_run+0x170/0x210 [ 134.937048] do_exit+0x8b5/0x2cb0 [ 134.937048] do_group_exit+0x108/0x330 [ 134.937048] get_signal+0x5e4/0x14f0 [ 134.937048] do_signal+0x83/0x1c90 [ 134.937048] exit_to_usermode_loop+0x1a5/0x210 [ 134.937048] Call Trace: [ 134.937048] [<ffffffff82be30ad>] dump_stack+0x6f/0xa2 [ 134.937048] [<ffffffff8175c984>] print_trailer+0xf4/0x150 [ 134.937048] [<ffffffff8176370f>] object_err+0x2f/0x40 [ 134.937048] [<ffffffff81765fb6>] kasan_report_error+0x256/0x550 [ 134.937048] [<ffffffff81455748>] ? mark_held_locks+0xc8/0x120 [ 134.937048] [<ffffffff85223e23>] ? snd_power_wait+0x2e3/0x380 [ 134.937048] [<ffffffff817664ae>] __asan_report_store4_noabort+0x3e/0x40 [ 134.937048] [<ffffffff852e0f68>] ? dummy_systimer_prepare+0x268/0x2a0 [ 134.937048] [<ffffffff852e0f68>] dummy_systimer_prepare+0x268/0x2a0 [ 134.937048] [<ffffffff852e141b>] dummy_pcm_prepare+0x7b/0xa0 [ 134.937048] [<ffffffff852563ca>] snd_pcm_do_prepare+0x5a/0x90 [ 134.937048] [<ffffffff852556b6>] snd_pcm_action_single+0x76/0x120 [ 134.937048] [<ffffffff85255ab5>] snd_pcm_action_nonatomic+0x95/0xa0 [ 134.937048] [<ffffffff85260a05>] snd_pcm_common_ioctl1+0x1045/0x21a0 [ 134.937048] [<ffffffff86659c34>] ? __mutex_unlock_slowpath+0x1f4/0x430 [ 134.937048] [<ffffffff8525f9c0>] ? snd_pcm_status_user+0x140/0x140 [ 134.937048] [<ffffffff86659e79>] ? mutex_unlock+0x9/0x10 [ 134.937048] [<ffffffff8529649c>] ? snd_pcm_oss_change_params+0xb2c/0x3580 [ 134.937048] [<ffffffff85261e02>] snd_pcm_playback_ioctl1+0x2a2/0x5e0 [ 134.937048] [<ffffffff85295970>] ? snd_pcm_hw_param_near.constprop.26+0x8f0/0x8f0 [ 134.937048] [<ffffffff85261b60>] ? snd_pcm_common_ioctl1+0x21a0/0x21a0 [ 134.937048] [<ffffffff85262906>] snd_pcm_kernel_ioctl+0x136/0x160 [ 134.937048] [<ffffffff852908bb>] snd_pcm_oss_prepare+0x4b/0x200 [ 134.937048] [<ffffffff85298f9e>] snd_pcm_oss_make_ready+0xae/0x120 [ 134.937048] [<ffffffff8529f58f>] snd_pcm_oss_write+0x15f/0x700 [ 134.937048] [<ffffffff81456670>] ? debug_check_no_locks_freed+0x3c0/0x3c0 [ 134.937048] [<ffffffff817bacd3>] __vfs_write+0x113/0x4b0 [ 134.937048] [<ffffffff8529f430>] ? snd_pcm_oss_ioctl_compat+0x30/0x30 [ 134.937048] [<ffffffff817babc0>] ? vfs_iter_write+0x360/0x360 [ 134.937048] [<ffffffff81493f27>] ? debug_lockdep_rcu_enabled+0x77/0x90 [ 134.937048] [<ffffffff829e63c5>] ? common_file_perm+0x155/0x3a0 [ 134.937048] [<ffffffff829e6822>] ? apparmor_file_permission+0x22/0x30 [ 134.937048] [<ffffffff8291d07c>] ? security_file_permission+0x8c/0x1f0 [ 134.937048] [<ffffffff817bc162>] ? rw_verify_area+0x102/0x2c0 [ 134.937048] [<ffffffff817bc797>] vfs_write+0x167/0x4a0 [ 134.937048] [<ffffffff817bfa81>] SyS_write+0x111/0x220 [ 134.937048] [<ffffffff817bf970>] ?

[alsa-devel] [PATCH] Revert "ALSA: hda - Fix noise on Gigabyte Z170X mobo"
by Takashi Iwai 05 Feb '16

05 Feb '16

This reverts commit 0c25ad80408e95e0a4fbaf0056950206e95f726f. The original commit disabled the aamixer path due to the noise problem, but it turned out that some mobo with the same PCI SSID doesn't suffer from the issue, and the disabled function (analog loopback) is still demanded by users. Since the recent commit [e7fdd52779a6: ALSA: hda - Implement loopback control switch for Realtek and other codecs], we have the dynamic mixer switch to enable/disable the aamix path, and we don't have to disable the path statically any longer. So, let's revert the disablement, so that only the user suffering from the noise problem can turn off the aamix on the fly.

[alsa-devel] [PATCH] ASoC: mxs-saif: check BUSY bit in hw_params() only if not mclk_in_use
by Mans Rullgard 05 Feb '16

05 Feb '16

If something else, typically a codec, has enabled mclk, the BUSY bit may be set when hw_params() is called without this being an error. This check thus causes intermittent failures to configure the sound device when used in such a manner. Fix this by making the test conditional on !saif->mclk_in_use.
