Introduce ACL man pages en masse for library calls, and general introduction.
Introduce ACL man pages en masse for library calls, and general introduction.
Also, fix acl_valid.c non-portable calls to include _np in their names,
making them standard-happy as well as consistent with acl.h

The caller should free any +releasable memory, when the new ACL is no longer required, by calling +.Xr acl_free 3 +with the +.Va (void *)acl_t +as an argument. +.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 pointer to the +internal representation of the ACL in working storage. Otherwise, a value +of +.Va (acl_t)NULL +shall be returned, and +.Va errno +shall be set to indicate the error. +.Sh ERRORS +If any of the following conditions occur, the +.Fn acl_from_text +function shall return a value of +.Va (acl_t)NULL +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 EINVAL +Argument +.Va buf_p +cannot be translated into an ACL. +.It Bq Er ENOMEM +The ACL working storage requires more memory than is allowed by the +hardware or system-imposed memory management constraints. +.El +.Sh SEE ALSO +.Xr acl 3 , +.Xr acl_free 3 , +.Xr acl_get 3 , +.Xr acl_to_text 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 FreeBSD 4.0, and development continues. +.Sh AUTHORS +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. + +.Fn acl_from_text +and +.Fn acl_to_text +rely on the +.Xr getpwent 3 +library calls to manage username and uid mapping, as well as the +.Xr getgrent 3 +library calls to manage groupname and gid mapping. These calls are not +thread safe, and so transitively, neither are +.Fn acl_from_text +and +.Fn acl_to_text . +These functions may also interfere with stateful +calls associated with the +.Fn getpwent +and +.Fn getgrent +calls. |
