I am rarely seeing this crash: r2: ospfd crashed. Core file found - Backtrace follows: [New LWP 32748] [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/aarch64-linux-gnu/libthread_db.so.1". Core was generated by `/usr/lib/frr/ospfd'. Program terminated with signal SIGABRT, Aborted. 2019-08-29 15:59:36,149 ERROR: assert failed at "test_ospf_sr_topo1/test_memory_leak": Which translates to this code: node = listhead(ospf->oi_write_q); assert(node); oi = listgetdata(node); assert(oi); So if we get into ospf_write without anything on the oi_write_q we are stopping the program. This is happening because in ospf_ls_upd_queue_send we are calling ospf_write. Imagine that we have a interface already on the on_write_q and then ospf_write handles the packet send for all functions. We are not clearing the t_write thread and we are popping and causing a crash. Additionally modify OSPF_ISM_WRITE_ON(O) to not just blindly turn on the t_write thread. Only do so if we have data. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com> ospfd: Remove redundant asserts assert(oi) is impossible all listgetdata(node) directly proceeding it already asserts here, besides a node cannot be created with a null pointer! If list_isempty is called directly before the listhead call it is impossilbe that we do not have a valid pointer here. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com> |
