Subject: [PATCH 0/7] netfilter: refactor deprecated strncpy
Date: Tue, 08 Aug 2023 22:48:05 +0000 [thread overview]
Message-ID: <20230808-net-netfilter-v1-0-efbbe4ec60af@google.com> (raw)
`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.
