[PATCH 0/7] netfilter: refactor deprecated strncpy

From: Justin Stitt
Date: Tue Aug 08 2023 - 18:48:38 EST


`strncpy` is deprecated for use on NUL-terminated destination strings [1].

A suitable replacement is `strscpy` [2] due to the fact that it
guarantees NUL-termination on its destination buffer argument which is
_not_ the case for `strncpy`!

This series of patches aims to swap out `strncpy` for more robust and
less ambiguous interfaces like `strscpy` and `strtomem`. This patch
series, if applied in its entirety, removes most if not all instances of
`strncpy` in the `net/netfilter` directory.
