Summary | 0006001: GNS recursion may go forever under very particular circumstances | ||||
Description | GNS (as per LSD0001) may delegate to the *system resolver* (GNUNET_RESOLVER_get_ip()) when encountering a CNAME. The system resolver may in turn call on GNS *if* the respective TLD is configured to be in GNS (for the user running gnunet-service-gns). In this case, the recursion limit is not obeyed. | ||||
Steps To Reproduce | Setup GNS with NSS integration. Create CNAME record in GNS to point to itself (i.e. value rec.bar in zone bar under label rec). Ensure 'rec' is recognized by NSS. | ||||
Tags | No tags attached. | ||||
|
Actually not, because libgnunetresolver does never trigger NSS in the current implementation, as it does its own asynchronous recursive DNS resolution. Hence it violates a 'SHOULD' clause in lsd0001, which at the same time makes it easy to satisfy the bounded recursion property. |
