Hi Santosh, I've been working on a memory leak bug reported by syzbot. https://syzkaller.appspot.com/bug?id=39b72114839a6dbd66c1d2104522698a813f9ae2 It seems that memory allocated in rds_send_probe function is not freed. Let me share my observations. rds_message is allocated at the beginning of rds_send_probe function. Then it is added to cp_send_queue list of rds_conn_path and refcount is increased by one. Next, in rds_send_xmit function it is moved from cp_send_queue list to cp_retrans list, and again refcount is increased by one. Finally in rds_loop_xmit function refcount is increased by one. So, total refcount is 4. However, rds_message_put is called three times, in rds_send_probe, rds_send_remove_from_sock and rds_send_xmit functions. It seems that one more rds_message_put is needed. Would you please check and share your comments on this issue? Thanks, Fatih
