Will add changes for other supported ACL systems shortly (Herb, I may
need help with the IRIX one).

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.

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(SMB_ACL_T posix_acl)
