From 75b1a8f9d62e50f05d0e4e9f3c8bcde32527ffc1 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 4 Jan 2021 09:17:34 -0800 Subject: ALSA: Convert strlcpy to strscpy when return value is unused strlcpy is deprecated. see: Documentation/process/deprecated.rst Change the calls that do not use the strlcpy return value to the preferred strscpy. Done with cocci script: @@ expression e1, e2, e3; @@ - strlcpy( + strscpy( e1, e2, e3); This cocci script leaves the instances where the return value is used unchanged. After this patch, sound/ has 3 uses of strlcpy() that need to be manually inspected for conversion and changed one day. $ git grep -w strlcpy sound/ sound/usb/card.c: len = strlcpy(card->longname, s, sizeof(card->longname)); sound/usb/mixer.c: return strlcpy(buf, p->name, buflen); sound/usb/mixer.c: return strlcpy(buf, p->names[index], buflen); Miscellenea: o Remove trailing whitespace in conversion of sound/core/hwdep.c Link: https://lore.kernel.org/lkml/CAHk-=wgfRnXz0W3D37d01q3JFkr_i_uTL=V6A6G1oUZcprmknw@mail.gmail.com/ Signed-off-by: Joe Perches Acked-by: Mark Brown Link: https://lore.kernel.org/r/22b393d1790bb268769d0bab7bacf0866dcb0c14.camel@perches.com Signed-off-by: Takashi Iwai --- sound/oss/dmasound/dmasound_core.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'sound/oss') diff --git a/sound/oss/dmasound/dmasound_core.c b/sound/oss/dmasound/dmasound_core.c index 38f25e97538f..49679aa8631d 100644 --- a/sound/oss/dmasound/dmasound_core.c +++ b/sound/oss/dmasound/dmasound_core.c @@ -355,8 +355,8 @@ static int mixer_ioctl(struct file *file, u_int cmd, u_long arg) { mixer_info info; memset(&info, 0, sizeof(info)); - strlcpy(info.id, dmasound.mach.name2, sizeof(info.id)); - strlcpy(info.name, dmasound.mach.name2, sizeof(info.name)); + strscpy(info.id, dmasound.mach.name2, sizeof(info.id)); + strscpy(info.name, dmasound.mach.name2, sizeof(info.name)); info.modify_counter = mixer.modify_counter; if (copy_to_user((void __user *)arg, &info, sizeof(info))) return -EFAULT; -- cgit v1.2.3
