Subject: [PATCH 01/30] xfs: reject invalid flags combinations in XFS_IOC_ATTRLIST_BY_HANDLE
Date: Wed, 29 Jan 2020 18:02:40 +0100 [thread overview]
Message-ID: <20200129170310.51370-2-hch@lst.de> (raw)
In-Reply-To: <20200129170310.51370-1-hch@lst.de>
While the flags field in the ABI and the on-disk format allows for
multiple namespace flags, that is a logically invalid combination and
listing multiple namespace flags will return no results as no attr
can have both set. Reject this case early with -EINVAL.
