| |
At domain_context_mapping_one(), if the domain is still not assign domain id, it will assign a new domain_id for it, but the newly creating domain id is not update to domain, so the domain will keep an unkown domain id.
It will cause the issues: like flush wrong domain in iommu->flush.flush_iotlb, and free/release wrong domain.
