Hello Roland!
I created this patch against your libibverbs git, stable branch.
Regards
Nam
increment counter comp_events_completed only if channel is set
this will prevent the while loop below in ibv_cmd_destroy_cq() to
hang if consumer calls ibv_ack_cq_events() without any assigned
channel
int ibv_cmd_destroy_cq(struct ibv_cq *cq)
{ ...
pthread_mutex_lock(&cq->mutex);
while (cq->comp_events_completed != resp.comp_events_reported ||
cq->async_events_completed != resp.async_events_reported)
