Agreed. In v3 qrtr_hello_work() reschedules itself when the allocation or qrtr_local_enqueue() fails. Once hello_sent is set it skips our HELLO and only retries the replay. > - [Low] In net/qrtr/af_qrtr.c, the new HELLO replay in qrtr_hello_work() > is not serialized against qrtr_endpoint_unregister(), so the replayed… Agreed. v3 queues the replay under ep_lock and only while node->ep is set. qrtr_endpoint_unregister() clears node->ep under ep_lock before it queues the BYE, so the replay either comes before the BYE or is not sent. https://lore.kernel.org/all/20261029105142.2503-1-26rote@gmail.com/ pw-bot: cr
