ALSA: seq: oss/rw: Cleanup with guard

2025-08-29T09:52:36+00:00

Replace the manual spin lock/unlock pairs with guard() for code simplification. Only code refactoring, and no behavior change. Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20250827080520.7544-12-tiwai@suse.de

ALSA: seq: oss/synth: Clean up with guard and auto cleanup

2025-08-29T09:52:36+00:00

Use the auto-cleanup for the refcount management of seq_oss_synth object. The explicit call of snd_use_lock_free() is dropped by the magic __free(seq_oss_synth) attribute. Along with that, replace the manual mutex and spin locks with guard(). Only code refactoring, and no behavior change.

ALSA: seq: Simplify internal command operation from OSS layer

2025-08-29T09:52:35+00:00

snd_seq_client_ioctl_lock() and *_unlock() are used only from a single function of the OSS layer, and it's just to wrap the call of snd_seq_kernel_client_ctl(). Provide another variant of snd_seq_kernel_client_ctl() that takes the locks internally and drop the ugly snd_seq_client_ioctl_lock() and *_unlock() implementations, instead.

ALSA: seq: Use safer strscpy() instead of strcpy()

2025-07-11T07:51:08+00:00

Use a safer function strscpy() instead of strcpy() for copying to arrays. Only idiomatic code replacement, and no functional changes. Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20250710100727.22653-4-tiwai@suse.de

ALSA: seq: oss: Send fragmented SysEx messages immediately

2024-12-31T11:56:01+00:00

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.
