ACL confusion

All,

I am trying to clear ACL's completely from all files and folders in a directory. I can get the directories as cleared as:

Code:
# owner: root
# group: root
user::rwx
group::r-x
other::rwx
default:user::rwx
default:group::r-x
default:other::r-x

What ever I do I can't remove the defaults from the directories. I have traversed back up the directory tree to confirm that there are no visible (no + at the end of any directories) ACL's present, but still the same behavior. I run:

Code:
# setfacl -k <dir>

and still receive:

Code:
# owner: root
# group: root
user::rwx
group::r-x
other::rwx
default:user::rwx
default:group::r-x
default:other::r-x

Can anyone shed some light on what using the '-k' flag does nothing, or provide some guidance as to possibly a '-x' flag string that would remove the default settings?

Nothing I have tried has worked.

Thank in advance,

HB

When did HP-UX have support for ACL?

Hello, I try to find what year HP-UX got support for ACL (Access Control List)? I know that HP-UX was the first Unix with ACL support, but it is very hard to find the information on when that occured. So anyone here know when that did happen? Any answers are appreciated, /eXpander (1 Reply)

acl_get_fd(3)						     Library Functions Manual						     acl_get_fd(3)

NAME
acl_get_fd - Retrieves the specified ACL associated with the specified file or directory LIBRARY
Security Library (libpacl.a) SYNOPSIS
#include <sys/acl.h> acl_t acl_get_fd( int fd); acl_type_t type_d); PARAMETERS
Designates the file descriptor of the file or directory to retrieve the ACL from. Designates the type of ACL to retrieve: ACL_TYPE_ACCESS, ACL_TYPE_DEFAULT, or ACL_TYPE_DEFAULT_DIR. DESCRIPTION
NOTE: This function is based on Draft 13 of the POSIX P1003.6 standard. The acl_get_fd() function retrieves the specified ACL for the given file descriptor. The acl_tag_t field designates if the ACL being retrieved is an access or default ACL. Working storage is allocated as needed. RETURN VALUES
Upon successful completion, the acl_get_fd() function returns a pointer to the working storage internal representation copy of the ACL. If the specified ACL type is ACL_TYPE_DEFAULT or ACL_TYPE_DEFAULT_DIR and the specified ACL doesn't exist for the given file descriptor a value of NULL is returned. If the specified ACL type is ACL_TYPE_ACCESS and the given file descriptor doesn't have an access ACL a pointer to the working storage internal representation copy of the permission bits in ACL format is returned. Otherwise, a value of NULL is returned and errno is set to indicate the error. ERRORS
If any of the following conditions occur, the acl_get_fd() function sets errno to the corresponding value: The required access to the file or directory was denied. The fd argument is not a valid file descriptor. The argument type_d is not a recognized ACL type. There is not enough memory available to the process to allocate the working storage. The type_d argument indicates a default ACL, and fd does not point to a directory. RELATED INFORMATION
