If anyone has any objections, please let me know. ------------------ From: Azeem Shaikh [ Upstream commit 37f1663c91934f664fb850306708094a324c227c ] strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). No return values were used, so direct replacement is safe.
