From: Thorsten Blum Date: Fri, 7 Mar 2025 11:35:47 +0000 (+0100) Subject: module: Replace deprecated strncpy() with strscpy() X-Git-Tag: v6.15-rc1~94^2~2 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=6380bf8ff90213282a7a7f99697964a9c2bd6899;p=thirdparty%2Flinux.git module: Replace deprecated strncpy() with strscpy() strncpy() is deprecated for NUL-terminated destination buffers; use strscpy() instead. The destination buffer ownername is only used with "%s" format strings and must therefore be NUL-terminated, but not NUL- padded. No functional changes intended.
