- This file wraps all differing system ACL interfaces into a consistent
- one based on the POSIX interface. It also returns the correct errors
- for older UNIX systems that don't support ACLs.
-
- The interfaces that each ACL implementation must support are as follows :
-
- int sys_acl_get_entry( SMB_ACL_T theacl, int entry_id, SMB_ACL_ENTRY_T *entry_p)
- int sys_acl_get_tag_type( SMB_ACL_ENTRY_T entry_d, SMB_ACL_TAG_T *tag_type_p)
- int sys_acl_get_permset( SMB_ACL_ENTRY_T entry_d, SMB_ACL_PERMSET_T *permset_p
- void *sys_acl_get_qualifier( SMB_ACL_ENTRY_T entry_d)
- SMB_ACL_T sys_acl_get_file( const char *path_p, SMB_ACL_TYPE_T type)
- SMB_ACL_T sys_acl_get_fd(int fd)
- int sys_acl_clear_perms(SMB_ACL_PERMSET_T permset);
- int sys_acl_add_perm( SMB_ACL_PERMSET_T permset, SMB_ACL_PERM_T perm);
- char *sys_acl_to_text( SMB_ACL_T theacl, ssize_t *plen)
- SMB_ACL_T sys_acl_init( int count)
- int sys_acl_create_entry( SMB_ACL_T *pacl, SMB_ACL_ENTRY_T *pentry)
- int sys_acl_set_tag_type( SMB_ACL_ENTRY_T entry, SMB_ACL_TAG_T tagtype)
- int sys_acl_set_qualifier( SMB_ACL_ENTRY_T entry, void *qual)
- int sys_acl_set_permset( SMB_ACL_ENTRY_T entry, SMB_ACL_PERMSET_T permset)
- int sys_acl_valid( SMB_ACL_T theacl )
- int sys_acl_set_file( const char *name, SMB_ACL_TYPE_T acltype, SMB_ACL_T theacl)
- int sys_acl_set_fd( int fd, SMB_ACL_T theacl)
- int sys_acl_delete_def_file(const char *path)
-
- This next one is not POSIX complient - but we *have* to have it !
- More POSIX braindamage.
-
- int sys_acl_get_perm( SMB_ACL_PERMSET_T permset, SMB_ACL_PERM_T perm)
-
- The generic POSIX free is the following call. We split this into
- several different free functions as we may need to add tag info
- to structures when emulating the POSIX interface.
-
- int sys_acl_free( void *obj_p)
-
- The calls we actually use are :
-
- int sys_acl_free_text(char *text) - free acl_to_text
- int sys_acl_free_acl(SMB_ACL_T posix_acl)
- int sys_acl_free_qualifier(void *qualifier, SMB_ACL_TAG_T tagtype)
