Subject: [PATCH] net: ipconfig: replace strncpy with strscpy_pad
Date: Wed,  9 Apr 2025 00:27:59 +0530	[thread overview]
Message-ID: <20250408185759.5088-1-pranav.tyagi03@gmail.com> (raw)

Replace the deprecated strncpy() function with strscpy_pad() as the
destination buffer is NUL-terminated and requires
trailing NUL-padding
