the previous commit introduced a possible race in getsigningtime() where the rdataset header could change between being found on the heap and being bound. getsigningtime() now looks at the first element of the heap, gathers the locknum, locks the respective lock, and retrieves the header from the heap again. If the locknum has changed, it will rinse and repeat. Theoretically, this could spin forever, but practically, it almost never will as the heap changes on the zone are very rare. we simplify matters further by changing the dns_db_getsigningtime() API call. instead of passing back a bound rdataset, we pass back the information the caller actually needed: the resigning time, owner name and type of the rdataset that was first on the heap. |
