loop back mounting emits two system calls: mount and mlockall. mount is obviously needed. mlockall is needed for encryption. As the result both CAP_SYS_ADMIN and CAP_IPC_LOCK are needed to do loopback mounting. The problem is that CAP_IPC_LOCK is always needed through my command doesn't need encryption. With the following patch, mount calls mlockall only when encryption is needed. Signed-off-by: Masatake YAMATO <jet@gyve.org> |
