From: Thorsten Blum Date: Tue, 18 Mar 2025 18:55:19 +0000 (+0100) Subject: netfilter: xtables: Use strscpy() instead of strscpy_pad() X-Git-Tag: v6.15-rc1~160^2~17^2~2 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3b4aff61ca5dd696856d2db98e9268d94504eff3;p=thirdparty%2Fkernel%2Flinux.git netfilter: xtables: Use strscpy() instead of strscpy_pad() kzalloc() already zero-initializes the destination buffer, making strscpy() sufficient for safely copying the name. The additional NUL- padding performed by strscpy_pad() is unnecessary. The size parameter is optional, and strscpy() automatically determines the size of the destination buffer using sizeof() if the argument is omitted. This makes the explicit sizeof() call unnecessary; remove it. No functional changes intended.
