Subject: [PATCH 00/20] Manual replacement of all strlcpy in favor of strscpy
strlcpy() copy a C-String into a sized buffer, the result is always a
valid NULL-terminated that fits in the buffer, howerver it has severals
issues. It reads the source buffer first, which is dangerous if it is non
NULL-terminated or if the corresponding buffer is unbounded. Its safe
replacement is strscpy(), as suggested in the deprecated interface [1].
We plan to make this contribution in two steps:
- Firsly all cases of strlcpy's return value are manually replaced by the
corresponding calls of strscpy() with the new handling of the return
value (as the return code is different in case of error).
- Then all other cases are automatically replaced by using coccinelle.
This series covers manual replacements.
