--- Comment #1 from CTurt <cturt@hardenedbsd.org> ---
Patch:
https://github.com/HardenedBSD/hardenedBSD-playground/commit/1bcd4a2c6f3a25=
6b2db03fc9421857a7f7963f34.patch

It may potentially be more pleasing to use:

    if (strnlen(din.ia_from, ICONV_CSNMAXLEN) >=3D ICONV_CSNMAXLEN)

But I opted for using `sizeof` on the string instead:

    if (strnlen(din.ia_from, sizeof(din.ia_from)) >=3D ICONV_CSNMAXLEN)
