Subject: [PATCH] Btrfs: Check CAP_DAC_READ_SEARCH for BTRFS_IOC_INO_PATHS
Date: Mon, 28 Jan 2013 20:33:31 +0900 [thread overview]
Message-ID: <20130128113332.3B4B76AC03A@msa102.auone-net.jp> (raw)
CAP_DAC_READ_SEARCH overrides read and search permission check on
file and directory. It seems fit for BTRFS_IOC_INO_PATHS.
