Replace the deprecated strncpy() with strscpy() as the destination buffer is NUL-terminated and does not require any trailing NUL-padding. Also increase the length to 252 as NUL-termination is guaranteed. Signed-off-by: Pranav Tyagi <redacted> --- net/ipv4/ipconfig.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
