The POSIX.1e routine, -.Fn acl_valid , -checks this validity only with POSIX.1e ACL semantics, and irrespective -of the context in which the ACL is to be used. The non-portable forms, -.Fn acl_valid_fd_np -and -.Fn acl_valid_file_np , -allow an ACL to be checked in the context of a specific acl type, -.Va type , -and file system object. In environments where additional ACL types are -supported than just POSIX.1e, this makes more sense. - -For POSIX.1e semantics, the checks include: -.Bd -literal -offset indent -The three required entries (ACL_USER_OBJ, ACL_GROUP_OBJ, -and ACL_OTHER) shall exist exactly once in the ACL. If -the ACL contains any ACL_USER, ACL_GROUP, or any other -implementation-defined entries in the file group class -then one ACL_MASK entry shall also be required. The ACL -shall contain at most on ACL_MASK entry. - -The qualifier field shall be unique among all entries of -the same POSIX.1e ACL facility defined tag type. The -tag type field shall contain valid values including any -implementation-defined values. Validation of the values -of the qualifier field is implementation-defined. -.Ed - -The POSIX.1e -.Fn acl_valid -function may reorder the ACL for the purposes of verification; the -non-portable validation functions will not. -.Sh IMPLEMENTATION NOTES -FreeBSD's support for POSIX.1e interfaces and features is still under -development at this time. -.Sh RETURN VALUES -Upon successful completion, the function shall return a value of zero. -Otherwise, a value of -1 shall be returned and -.Va errno -shall be set to indicate the error. -.Sh ERRORS -If any of the following conditions occur, these functions shall return --1 and set -.Va errno -to the corresponding value: -.Bl -tag -width Er -.It Bq Er EACCES -Search permission is denied for a component of the path prefix, or the -object exists and the process does not have appropriate access rights. -.It Bq Er EBADF -The -.Va fd -argument is not a valid file descriptor. -.It Bq Er EINVAL -Argument -.Va acl -does not point to a valid ACL. - -One or more of the required ACL entries is not present in -.Va acl . - -The ACL contains entries that are not unique. - -The file system rejects the ACL based on fs-specific semantics issues. -.It Bq Er ENAMETOOLONG -A component of a pathname exceeded 255 characters, or an -entire path name exceeded 1023 characters. -.It Bq Er ENOENT -The named object does not exist, or the -.Va path_p -argument points to an empty string. -.It Bq Er ENOMEM -Insufficient memory available to fulfill request. -.It Bq Er EOPNOTSUPP -The file system does not support ACL retrieval. -.El -.Sh SEE ALSO -.Xr acl 3 , -.Xr acl_get 3 , -.Xr acl_init 3 , -.Xr acl_set 3 , -.Xr posix1e 3 -.Sh STANDARDS -POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion -of the draft continues on the cross-platform POSIX.1e implementation -mailing list. To join this list, see the FreeBSD POSIX.1e implementation -page for more information. -.Sh HISTORY -POSIX.1e support was introduced in -.Fx 4.0 , -and development continues. -.Sh AUTHORS -.An Robert N M Watson -.Sh BUGS -These features are not yet fully implemented. In particular, the shipped -version of UFS/FFS does not support storage of additional security labels, -and so is unable to (easily) provide support for most of these features. |
