2025-01-08ASoC: renesas: rz-ssi: Add a check for negative sample_spaceDan Carpenter
My static checker rule complains about this code. The concern is that if "sample_space" is negative then the "sample_space >= runtime->channels" condition will not work as intended because it will be type promoted to a high unsigned int value. strm->fifo_sample_size is SSI_FIFO_DEPTH (32). The SSIFSR_TDC_MASK is 0x3f. Without any further context it does seem like a reasonable warning and it can't hurt to add a check for negatives.

2025-01-01ALSA: seq: Make dependency on UMP clearerTakashi Iwai
CONFIG_SND_SEQ_UMP_CLIENT is a Kconfig for a sequencer client corresponding to the UMP rawmidi, while we have another major knob CONFIG_SND_SEQ_UMP that specifies whether the sequencer core supports UMP packets or not. Strictly speaking both of them are independent, but practically seen, it makes no sense to enable CONFIG_SND_SEQ_UMP_CLIENT without UMP support itself. This patch makes such an implicit dependency clearer. Now CONFIG_SND_SEQ_UMP_CLIENT depends on both CONFIG_SND_UMP and CONFIG_SND_SEQ_UMP. Meanwhile, CONFIG_SND_SEQ_UMP is enabled as default when CONFIG_SND_UMP is set.

2024-12-31ALSA: seq: oss: Send fragmented SysEx messages immediatelyTakashi Iwai
The recent bug report spotted on the old OSS sequencer code that tries to combine incoming SysEx messages to a single sequencer event. This is good, per se, but it has more demerits: - The sysex message delivery is delayed until the very last event - The use of internal buffer forced the serialization The recent fix in commit 0179488ca992 ("ALSA: seq: oss: Fix races at processing SysEx messages") addressed the latter, but a better fix is to handle the sysex messages immediately, i.e. just send each incoming fragmented sysex message as is. And this patch implements that. This resulted in a significant cleanup as well. Note that the only caller of snd_seq_oss_synth_sysex() is snd_seq_oss_process_event(), and all its callers dispatch the event immediately, so we can just put the passed buffer pointer to the event record to be handled.

2024-12-30ALSA: Align the syntax of iov_iter helpers with standard onesTakashi Iwai
We introduced a couple of helpers for copying iomem over iov_iter, and the functions were formed like the former copy_from/to_user(), and the return value was adjusted to 0/-EFAULT, which made the code transition a bit easier at that time. OTOH, the standard copy_from/to_iter() functions have different argument orders and the return value, and this difference can be confusing. It's not only confusing but dangerous; actually I did write a wrong code due to that once :-< For reducing the confusion, this patch changes the syntax of those helpers to align with the standard copy_from/to_iter(). The argument order is changed and the return value is the size of copied bytes. The callers of those functions are updated accordingly, too.

2024-12-30Revert "ALSA: ump: Don't enumeration invalid groups for legacy rawmidi"Takashi Iwai
This reverts commit c2d188e137e77294323132a760a4608321a36a70. Although it's fine to filter the invalid UMP groups at the first probe time, this will become a problem when UMP groups are updated and (re-)activated. Then there is no way to re-add the substreams properly for the legacy rawmidi, and the new active groups will be still invisible. So let's revert the change. This will move back to showing the full 16 groups, but it's better than forever lost. Link: https://patch.msgid.link/20241230114023.3787-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2024-12-30ALSA: seq: oss: Fix races at processing SysEx messagesTakashi Iwai
OSS sequencer handles the SysEx messages split in 6 bytes packets, and ALSA sequencer OSS layer tries to combine those. It stores the data in the internal buffer and this access is racy as of now, which may lead to the out-of-bounds access. As a temporary band-aid fix, introduce a mutex for serializing the process of the SysEx message packets.

2024-12-30ALSA: compress_offload: fix remaining descriptor races in ↵Al Viro
sound/core/compress_offload.c 3d3f43fab4cf ("ALSA: compress_offload: improve file descriptors installation for dma-buf") fixed some of descriptor races in snd_compr_task_new(), but there's a couple more left. We need to grab the references to dmabuf before moving them into descriptor table - trying to do that by descriptor afterwards might end up getting a different object, with a dangling reference left in task->{input,output} Fixes: 3d3f43fab4cf ("ALSA: compress_offload: improve file descriptors installation for dma-buf") Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Link: https://patch.msgid.link/20241229185232.GA1977892@ZenIV Signed-off-by: Takashi Iwai <tiwai@suse.de>
2024-12-30ALSA: compress_offload: Drop unneeded no_free_ptr()Takashi Iwai
The error path for memdup_user() no longer needs the tricky wrap with no_free_ptr() and we can safely return the error pointer directly.

Driver will return error if no SUBSYS_ID found in BIOS(acpi). It will cause error in tas2563 projects, which have no SUBSYS_ID.
