Sorry, I made several mistakes in the previous email.
The changes to access_container in qaccess.pc should be:
int access_container(struct query *q, char *argv[], client *cl)
{
EXEC SQL BEGIN DECLARE SECTION;
int cnt_id, acl_id, memacl_id;
char acl_type[CONTAINERS_ACL_TYPE_SIZE],
memacl_type[CONTAINERS_ACL_TYPE_SIZE];
char name[CONTAINERS_CNAME_SIZE], *newname;
EXEC SQL END DECLARE SECTION;
int status;
cnt_id = *(int *)argv[0];
/* if amcn or dmcn, container id is the second argument */
if (strcmp(q->shortname, "amcn") == 0 || strcmp(q->shortname, "dmcn") == 0)
cnt_id = *(int *)argv[1];
EXEC SQL SELECT acl_id, acl_type, memacl_id, memacl_type, name
INTO :acl_id, :acl_type, :memacl_id, :memacl_type, :name
FROM containers
WHERE cnt_id = :cnt_id;
if (sqlca.sqlerrd[2] != 1)
return MR_INTERNAL;
/* if the query is update_container and the containers is to be renamed
* and it is a top-level container, only dbadmin can do it */
if (!strcmp(q->shortname, "ucon"))
{
newname = argv[1];
if (strcmp(name, newname) && strchr(name, '/') == NULL)
return MR_PERM;
}
/* check for client in access control list and return success right
* away if it's there. */
if (find_member(acl_type, acl_id, cl))
return MR_SUCCESS;
/* If not amcn, dmcn, we lose. */
if (strcmp(q->shortname, "amcn") && strcmp(q->shortname, "dmcn"))
return MR_PERM;
if (find_member(memacl_type, memacl_id, cl))
return MR_SUCCESS;
/* Otherwise fail. */
return MR_PERM;
}
