2020-06-25ALSA: core: Warn on empty moduleTakashi Iwai
The module argument passed to snd_card_new() must be a valid non-NULL pointer when the module support is enabled. Since ASoC driver passes the argument from each snd_soc_card definition, one may forget to set the owner field and lead to a NULL module easily. For catching such an overlook, add a WARN_ON() in snd_card_new(). Also, put the card->module assignment in the ifdef block for a very minor optimization.

2020-06-19Merge branch 'topic/hda-micmute-led' into for-nextTakashi Iwai
This is a patch set inspired by the recent patch Kai-Heng posted about the HD-audio mic-mute LED control. Currently HD-audio driver deals with the mute and mic-mute LED in several different ways: primarily with the direct callback of vmaster hook and capture sync hook, while another with the LED class device binding. The latter has been used for binding with the platform device LEDs like Thinkpad, Dell, Huawei. And, yet, recently we added our own LED classdev for the mic-mute LED on some HP systems although they are controlled directly with the callback; it's exposed, however, for the DMIC that is governed by a different ASoC driver. This patch set is an attempt to sort out and make them consistent: namely, * All LEDs are now controlled via LED class device * The generic driver provides helper functions to easily build up the LED class dev and the relevant mixer controls * Conversion of the existing framework and clean ups The patches are lightly tested in my side with a couple of machines and also through hda-emu tests. Some devices receive new kcontrols for the mute LED behavior (that have been missing so far), but anything else look good though my tests.

2020-06-19ALSA: hda: Enable sync-write operation as default for all controllersTakashi Iwai
In the end we already enabled the sync-write mode for most of HD-audio controllers including Intel, and it's no big merit to keep the async write mode for the rest. Let's make it as default and drop the superfluous AZX_DCAPS_SYNC_WRITE bit flag. Also, avoid to set the allow_bus_reset flag, which is a quite unstable and hackish behavior that was needed only for some early platforms (decades ago). The straight fallback to the single cmd mode is more robust. Link: https://lore.kernel.org/r/20200618144051.7415-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2020-06-18ALSA: hda: Let LED cdev handling suspend/resumeTakashi Iwai
Set LED_CORE_SUSPENDRESUME to LED cdev flags, so that the LED core would store and restore the LED status at suspend/resume. In theory, the codec driver should be responsible for all LED bits, but this might be safer and cover the overlooked cases.

2020-06-18ALSA: hda/realtek: Unify LED helper codeTakashi Iwai
Both mute and mic-mute LED callbacks do almost similar tasks with just different bits. Factor out the common code and use them from the callbacks for simplification. This ended up with covering the forgotten stuff, too; e.g. VREF LED handling required the temporary power up/down that was missing for the mute LED, or some forgotten polarity checks are added.

2020-06-18ALSA: hda/sigmatel: Use the new vmaster mute LED helperTakashi Iwai
Convert the mute LED handling in Sigmatel/IDT codec to the new vmaster mute helper. A point to be cautiously handled is that the value passed to the callback is inverted; the vmaster passes "enabled" (0 = mute), while LED classdev passes "brightness" (1 = mute). A positive side-effect by this change is that the driver gets also the enum controls for the mute behavior like other drivers already had.

Convert the mute LED handling in Conexant codec to the new vmaster mute helper. A point to be cautiously handled is that the value passed to the callback is inverted; the vmaster passes "enabled" (0 = mute), while LED classdev passes "brightness" (1 = mute). Also the assignment of the default vmaster hook is moved at a later point after the mute hook is set up. This assures no nested hook. Finally, since we enable the mute-LED kcontrols always in the helper side, the extra vmaster_mute_enum flag set up is dropped.

A new helper, snd_hda_gen_add_micmute_led_cdev(), is introduced here for creating a LED classdev and setting up the hook to the capture control for controlling the mic-mute LED to follow the capture switch change. This will replace the existing users of snd_hda_gen_add_micmute_led() in later patches. Also, introduce a new kconfig CONFIG_SND_HDA_GENERIC_LEDS, to indicate the usage of mute / mic-mute LED helpers. It's selected by the codec drivers (Realtek, Conexant and Sigmatel), while it selects the necessary LED class dependencies.

2020-06-15ALSA: pcm: Use SG-buffer only when direct DMA is availableTakashi Iwai
The DMA-coherent SG-buffer is tricky to use, as it does need the mapping. It used to work stably on x86 over years (and that's why we had enabled SG-buffer on solely x86) with the default mmap handler and vmap(), but our luck seems no forever success. The chance of breakage is high when the special DMA handling is introduced in the arch side. In this patch, we change the buffer allocation to use the SG-buffer only when the device in question is with the direct DMA. It's a bit hackish, but it's currently the only condition that may work (more or less) reliably with the default mmap and vmap() for mapping the pages that are deduced via virt_to_page(). In theory, we can apply the similar hack in the sound/core memory allocation helper, too; but it's used by SOF for allocating SG pages without re-mapping via vmap() or mmap, and it's fine to use it in that way, so let's keep it and adds the workaround in PCM side.

2020-06-15ALSA: memalloc: Make SG-buffer helper usable for continuous buffer, tooTakashi Iwai
We have a few helper functions for making the access to the buffer address easier on SG-buffer. Those are specific to the buffer that is allocated with SG-buffer type, and it makes hard to use both SG and non-SG buffers in the same code. This patch adds a few simple checks and lets the helpers to deal with both SG- and continuous buffers gracefully. It's a preliminary step for the upcoming patch that mimics the buffer type on the fly. Link: https://lore.kernel.org/r/20200615160045.2703-4-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>

Some fields in snd_dma_buffer aren't touched in snd_dma_alloc_pages() and might be left uninitialized. Let's clear all fields properly, so that we can use a NULL check (e.g. dmab->private_data) as conditional in a later patch.

2020-06-15ALSA: pcm: Use dma_mmap_coherent() on x86, tooTakashi Iwai
We avoided the explicit use of dma_mmap_coherent() on x86 because of a spurious warning in x86 APT code in the past. However, this blindly assumes that the pages allocated via dma_alloc_coherent() on x86 are the ones convertible via virt_to_page() (that is used in the default mmap handler), and it's no longer true; with the indirect DMA ops, this can be handled differently. The only certain way for doing mmap such pages is the dma_mmap_coherent(), and the warning seems already gone in the recent code, so let's use it consistently.

2020-06-15ALSA: firewire-motu: wait for notification when changing clock configuration ↵Takashi Sakamoto
for protocol v3 It costs expensive to change clock configuration for models of protocol version 3. In current implementation, speculative strategy is used to finish the operation; just waiting for 4 seconds. As long as I investigate, when accepting and changing clock status actually, the device sends notification with mask. This commit uses wise way to wait for the notification after changing sampling clock rate during 4 seconds.

The SafeSetID LSM uses the security_task_fix_setuid hook to filter set*uid() syscalls according to its configured security policy. In preparation for adding analagous support in the LSM for set*gid() syscalls, we add the requisite hook here. Tested by putting print statements in the security_task_fix_setgid hook and seeing them get hit during kernel boot.

2020-06-14Revert "btrfs: switch to iomap_dio_rw() for dio"David Sterba
This reverts commit a43a67a2d715540c1368b9501a22b0373b5874c0. This patch reverts the main part of switching direct io implementation to iomap infrastructure. There's a problem in invalidate page that couldn't be solved as regression in this development cycle. The problem occurs when buffered and direct io are mixed, and the ranges overlap. Although this is not recommended, filesystems implement measures or fallbacks to make it somehow work. In this case, fallback to buffered IO would be an option for btrfs (this already happens when direct io is done on compressed data), but the change would be needed in the iomap code, bringing new semantics to other filesystems. Another problem arises when again the buffered and direct ios are mixed, invalidation fails, then -EIO is set on the mapping and fsync will fail, though there's no real error. There have been discussions how to fix that, but revert seems to be the least intrusive option.

2020-06-13net: ethernet: ti: ale: fix allmulti for nu type aleGrygorii Strashko
On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow unregistered mcast packets to pass. This happens, because ALE VLAN entries on these SoCs do not contain port masks for reg/unreg mcast packets, but instead store indexes of ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for reg/unreg mcast packets. This path was missed by commit 9d1f6447274f ("net: ethernet: ti: ale: fix seeing unreg mcast packets with promisc and allmulti disabled"). Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().
