Subject: [PATCH v13 49/51] nfs: Distinguish missing users and groups from nobody
Date: Tue,  3 Nov 2015 16:17:25 +0100	[thread overview]
Message-ID: <1446563847-14005-50-git-send-email-agruenba@redhat.com> (raw)
In-Reply-To: <1446563847-14005-1-git-send-email-agruenba@redhat.com>

User and group names are mapped to IDs using the kernel keyring infrastructure.
When a name does not exist, it is mapped to the nobody user or group; there is
no way to tell the difference from the mapping result.

In ACLs, we need to make that distinction.  For that, use the new "xuid" and
"xgid" maps: they behave like the old "uid" and "gid" maps except that the IDs
of existing users and groups are prefixed by a "+" sign.

When the "xuid" or "xgid" maps are not supported, nfs falls back to the "uid"
and "gid" maps.
