2022-02-16ALSA: line6: Fix misplaced backport of "Fix wrong altsetting for ↵Guillaume Bertholon
LINE6_PODHD500_1" The upstream commit 70256b42caaf ("ALSA: line6: Fix wrong altsetting for LINE6_PODHD500_1") changed the .altsetting field of the LINE6_PODHD500_1 entry in podhd_properties_table from 1 to 0. However, its backported version in stable (commit ec565611f930 ("ALSA: line6: Fix wrong altsetting for LINE6_PODHD500_1")) change the .altsetting field of the LINE6_PODHD500_0 entry instead. This patch resets the altsetting of LINE6_PODHD500_0 to 1, and sets the altsetting of LINE6_PODHD500_1 to 0, as wanted by the original fix.

2022-01-27ALSA: seq: Set upper limit of processed eventsTakashi Iwai
[ Upstream commit 6fadb494a638d8b8a55864ecc6ac58194f03f327 ] Currently ALSA sequencer core tries to process the queued events as much as possible when they become dispatchable. If applications try to queue too massive events to be processed at the very same timing, the sequencer core would still try to process such all events, either in the interrupt context or via some notifier; in either away, it might be a cause of RCU stall or such problems. As a potential workaround for those problems, this patch adds the upper limit of the amount of events to be processed. The remaining events are processed in the next batch, so they won't be lost. For the time being, it's limited up to 1000 events per queue, which should be high enough for any normal usages.

2021-12-14ALSA: ctl: Fix copy of updated id with element read/writeAlan Young
commit b6409dd6bdc03aa178bbff0d80db2a30d29b63ac upstream. When control_compat.c:copy_ctl_value_to_user() is used, by ctl_elem_read_user() & ctl_elem_write_user(), it must also copy back the snd_ctl_elem_id value that may have been updated (filled in) by the call to snd_ctl_elem_read/snd_ctl_elem_write(). This matches the functionality provided by snd_ctl_elem_read_user() and snd_ctl_elem_write_user(), via snd_ctl_build_ioff(). Without this, and without making additional calls to snd_ctl_info() which are unnecessary when using the non-compat calls, a userspace application will not know the numid value for the element and consequently will not be able to use the poll/read interface on the control file to determine which elements have updates.

2021-12-08ALSA: ctxfi: Fix out-of-range accessTakashi Iwai
commit 76c47183224c86e4011048b80f0e2d0d166f01c2 upstream. The master and next_conj of rcs_ops are used for iterating the resource list entries, and currently those are supposed to return the current value. The problem is that next_conf may go over the last entry before the loop abort condition is evaluated, and it may return the "current" value that is beyond the array size. It was caught recently as a GPF, for example. Those return values are, however, never actually evaluated, hence basically we don't have to consider the current value as the return at all. By dropping those return values, the potential out-of-range access above is also fixed automatically. This patch changes the return type of master and next_conj callbacks to void and drop the superfluous code accordingly.

commit 827b0913a9d9d07a0c3e559dbb20ca4d6d285a54 upstream. The recent fix for DAPM to correct the kctl change notification by the commit 5af82c81b2c4 ("ASoC: DAPM: Fix missing kctl change notifications") caused other regressions since it changed the behavior of snd_soc_dapm_set_pin() that is called from several API functions.

commit c0317c0e87094f5b5782b6fdef5ae0a4b150496c upstream. When the timer instance was add into ack_list but was not currently in process, the user could stop it via snd_timer_stop1() without delete it from the ack_list. Then the user could free the timer instance and when it was actually processed UAF occurred. This issue could be reproduced via testcase snd_timer01 in ltp - running several instances of that testcase at the same time. What I actually met was that the ack_list of the timer broken and the kernel went into deadloop with irqoff. That could be detected by hardlockup detector on board or when we run it on qemu, we could use gdb to dump the ack_list when the console has no response. To fix this issue, we delete the timer instance from ack_list and active_list unconditionally in snd_timer_stop1().

2021-10-27ALSA: hda: avoid write to STATESTS if controller is in resetKai Vehmanen
[ Upstream commit b37a15188eae9d4c49c5bb035e0c8d4058e4d9b3 ] The snd_hdac_bus_reset_link() contains logic to clear STATESTS register before performing controller reset. This code dates back to an old bugfix in commit e8a7f136f5ed ("[ALSA] hda-intel - Improve HD-audio codec probing robustness"). Originally the code was added to azx_reset(). The code was moved around in commit a41d122449be ("ALSA: hda - Embed bus into controller object") and ended up to snd_hdac_bus_reset_link() and called primarily via snd_hdac_bus_init_chip(). The logic to clear STATESTS is correct when snd_hdac_bus_init_chip() is called when controller is not in reset. In this case, STATESTS can be cleared. This can be useful e.g. when forcing a controller reset to retry codec probe. A normal non-power-on reset will not clear the bits. However, this old logic is problematic when controller is already in reset. The HDA specification states that controller must be taken out of reset before writing to registers other than GCTL.CRST (1.0a spec, 3.3.7). The write to STATESTS in snd_hdac_bus_reset_link() will be lost if the controller is already in reset per the HDA specification mentioned. This has been harmless on older hardware. On newer generation of Intel PCIe based HDA controllers, if configured to report issues, this write will emit an unsupported request error. If ACPI Platform Error Interface (APEI) is enabled in kernel, this will end up to kernel log. Fix the code in snd_hdac_bus_reset_link() to only clear the STATESTS if the function is called when controller is not in reset. Otherwise clearing the bits is not possible and should be skipped.

commit 5af82c81b2c49cfb1cad84d9eb6eab0e3d1c4842 upstream. The put callback of a kcontrol is supposed to return 1 when the value is changed, and this will be notified to user-space. However, some DAPM kcontrols always return 0 (except for errors), hence the user-space misses the update of a control value. This patch corrects the behavior by properly returning 1 when the value gets updated.

2021-10-27ALSA: seq: Fix a potential UAF by wrong private_free call orderTakashi Iwai
commit 1f8763c59c4ec6254d629fe77c0a52220bd907aa upstream. John Keeping reported and posted a patch for a potential UAF in rawmidi sequencer destruction: the snd_rawmidi_dev_seq_free() may be called after the associated rawmidi object got already freed. After a deeper look, it turned out that the bug is rather the incorrect private_free call order for a snd_seq_device. The snd_seq_device private_free gets called at the release callback of the sequencer device object, while this was rather expected to be executed at the snd_device call chains that runs at the beginning of the whole card-free procedure. It's been broken since the rewrite of sequencer-device binding (although it hasn't surfaced because the sequencer device release happens usually right along with the card device release). This patch corrects the private_free call to be done in the right place, at snd_seq_device_dev_free().

However, I forgot that the dma_addr field is still not set up for the CONTINUOUS buffer type (that this driver uses) yet in 5.14 and earlier kernels, and it resulted in garbage I/O. The problem will be fixed in 5.15, but we need to address it quickly for now. The fix is to deduce the address again from the DMA pointer with virt_to_phys(), but from the right one, substream->runtime->dma_area.

2021-08-15ALSA: seq: Fix racy deletion of subscriberTakashi Iwai
commit 97367c97226aab8b298ada954ce12659ee3ad2a4 upstream. It turned out that the current implementation of the port subscription is racy. The subscription contains two linked lists, and we have to add to or delete from both lists. Since both connection and disconnection procedures perform the same order for those two lists (i.e. src list, then dest list), when a deletion happens during a connection procedure, the src list may be deleted before the dest list addition completes, and this may lead to a use-after-free or an Oops, even though the access to both lists are protected via mutex. The simple workaround for this race is to change the access order for the disconnection, namely, dest list, then src list. This assures that the connection has been established when disconnecting, and also the concurrent deletion can be avoided.

commit 1c2b9519159b470ef24b2638f4794e86e2952ab7 upstream. SB16 CSP driver may hit potentially a typical ABBA deadlock in two code paths: In snd_sb_csp_stop(): spin_lock_irqsave(&p->chip->mixer_lock, flags); spin_lock(&p->chip->reg_lock); In snd_sb_csp_load(): spin_lock_irqsave(&p->chip->reg_lock, flags); spin_lock(&p->chip->mixer_lock); Also the similar pattern is seen in snd_sb_csp_start(). Although the practical impact is very small (those states aren't triggered in the same running state and this happens only on a real hardware, decades old ISA sound boards -- which must be very difficult to find nowadays), it's a real scenario and has to be fixed. This patch addresses those deadlocks by splitting the locks in snd_sb_csp_start() and snd_sb_csp_stop() for avoiding the nested locks.

We need to set the driver_name to "tegra" in order to get a usable lookup path for the updated ALSA UCMs. The new UCM lookup path has a form of driver_name/card_name. The old lookup paths that are based on driver module name continue to work as before. Note that UCM matching never worked for Tegra ASoC drivers if they were compiled as built-in, this is fixed by supporting the new naming scheme.
