fs: allow AT_EMPTY_PATH in linkat(), limit that to CAP_DAC_READ_SEARCH We don't want to allow creation of private hardlinks by different application using the fd passed to them via SCM_RIGHTS. So limit the null relative name usage in linkat syscall to CAP_DAC_READ_SEARCH Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
