Comment 1 Jeremy Allison 2020-05-06 20:22:36 UTC

On initial connect MacOS catalina connects to mdssvc.c pipe. If the  "UTF8-NFD" or "UTF8-NFC" iconv conversions are not installed, the error exits on this pipe cause an smbd crash trying to free an iconv handle of (-1).

Have patch, need bugnumber.

git-am fix for 4.12.next.

Cherry-pick from master. Applies cleanly. Only needed for 4.12.next, not previous versions.

Reassigning to Karolin for inclusion in 4.12.
