/*
|
|
* acl_valid: accepts an ACL, returns 0 on valid ACL, -1 for invalid,
|
|
* and errno set to EINVAL.
|
|
*
|
|
* Implemented by calling the acl_check routine in acl_support, which
|
|
* requires ordering. We call acl_support's _posix1e_acl_sort to make this
|
|
* true. POSIX.1e allows acl_valid() to reorder the ACL as it sees fit.
|
|
*
|
|
* This call is deprecated, as it doesn't ask whether the ACL is valid
|
|
* for a particular target. However, this call is standardized, unlike
|
|
* the other two forms.
