From a27bf0c83947b5ebc1e2970c3cfb92cb6d75af74 Mon Sep 17 00:00:00 2001 From: Jason Wang Date: Wed, 22 Dec 2021 11:27:07 +0800 Subject: [PATCH] ipmi: ssif: replace strlcpy with strscpy The strlcpy should not be used because it doesn't limit the source length. So that it will lead some potential bugs. But the strscpy doesn't require reading memory from the src string beyond the specified "count" bytes, and since the return value is easier to error-check than strlcpy()'s. In addition, the implementation is robust to the string changing out from underneath it, unlike the current strlcpy() implementation. Thus, replace strlcpy with strscpy.
