Subject: getcon family: returning success while context is NULL
Date: Fri, 24 Jul 2020 14:34:05 +0200	[thread overview]
Message-ID: <CAJ2a_DfV0M1zD=fjQOGq3KPcBtvQxrgtZHSbBKDcxuOX7pJygA@mail.gmail.com> (raw)

Hi list,

I stumbled over a systemd commit [1], handling the event where
getcon_raw returns 0 (success) and the returned context is NULL.
The commit points to the SELinux userland source lines [2].

Is this by design?
Or should either errno be set to ENODATA and ret to -1, or this case
be mentioned in the manpage?
