Subject: [PATCH 00/10] Annotate arguments of memtostr/strtomem with __nonstring
Date: Thu,  6 Feb 2025 17:00:09 -0800	[thread overview]
Message-ID: <20250207005832.work.324-kees@kernel.org> (raw)

Hi,

The memtostr*() and strtomem*() helpers are designed to move between C
strings (NUL-terminated) and byte arrays (that may just be zero padded and
may not be NUL-terminated). The "nonstring" attribute is used to annotated
these kinds of byte arrays, and we can validate the annotation on the
arguments of the helpers. Add the the infrastructure to do this, and
then update all the places where these annotations are currently missing.
