Michał Kępień efcba4dd23 Do not destroy IXFR journal in xfrin_end() ... The xfrin_end() function is run when a zone transfer is finished or canceled. One of the actions it takes for incremental transfers (IXFR) is calling dns_journal_destroy() on the zone journal structure that is stored in the relevant zone transfer context (xfr->ixfr.journal). That immediately invalidates that structure as it is not reference-counted. However, since the changes present in the IXFR stream are applied to the journal asynchronously (via isc_work_enqueue()), it is possible that some zone changes may still be in the process of being written to the journal by the time xfrin_end() destroys the relevant structure. Such a scenario leads to crashes. Fix by not destroying the zone journal structure until the entire zone transfer context is destroyed. xfrin_destroy() already conditionally calls dns_journal_destroy() and when the former is called, all asynchronous work for a given zone transfer process is guaranteed to be complete.		2023-12-20 17:21:14 +01:00
