ALSA: wavefront: copy userspace array safely

2023-11-20T11:38:31+00:00

wavefront_fx.c utilizes memdup_user() to copy a userspace array. This does not check for an overflow. Use the new wrapper memdup_array_user() to copy the array more safely.

ALSA: cs4231: Fix -Wformat-truncation warning for longname string

2023-09-15T11:23:01+00:00

The filling of card->longname can be gracefully truncated, as it's only informative. Use scnprintf() and suppress the superfluous compile warning with -Wformat-truncation. Link: https://lore.kernel.org/r/20230915091313.5988-3-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: sscape: Fix -Wformat-truncation warning

2023-09-15T11:21:32+00:00

The warning with -Wformat-truncation at sscape_upload_microcode() is false-positive; the version number can be only a single digit, hence fitting with the given string size. For suppressing the warning, replace snprintf() with scnprintf(). As stated in the above, truncation doesn't matter.

ALSA: sb: Fix wrong argument in commented code

2023-09-02T06:11:55+00:00

While rewriting the code from sockptr_t to iov_iter during the development, I forgot to replace one place in emu8000-pcm code. As it's in the disabled area (with ifdef), it's never built and overlooked. Replace with the proper argument NULL.

ALSA: emu8000: Convert to generic PCM copy ops

2023-08-18T10:18:19+00:00

This patch converts the SB Emu8000 driver code to use the new unified PCM copy callback. The conversion is a bit complicated because of many open code in emu8000_pcm.c. GET_VAL() and LOOP_WRITE() macros were rewritten / simplified with copy_from_iter(). As copy_from_iter() updates the internal offset value, we can drop the corresponding part, too.

ALSA: gus: Convert to generic PCM copy ops

2023-08-18T10:18:18+00:00

This patch converts the GUS driver code to use the new unified PCM copy callback. It's a straightforward conversion from *_user() to *_iter() variants. Note that copy_from/to_iter() returns the copied bytes, hence the error condition is adjusted accordingly.
