[ovs-dev] [PATCH] ovsdb-idl: Force reconnect when missing updates encountered.

2020-03-26 Thread Dumitru Ceara
When processing update2 messages, if the IDL detects that previous updates were missed, clear db->last_id and trigger a reconnect such that the IDL refreshes its complete view of the database. Such scenarios can happen for example when bugs in ovsdb-server/ovsdb-idl are encountered. One such situa

2020-03-26 Thread Yifeng Sun
Tun_metadata can be referened by flow and frozen_state at the same time. When ovs-vswitchd handles TLV table mod message, the involved tun_metadata gets freed. The call trace to free tun_metadata is shown as below: ofproto_run - handle_openflow - handle_single_part_openflow - handle_tlv_tabl

This patch enhances a system traffic test to prevent regression on the tunnel metadata table (tun_table) handling with frozen state. Without a proper fix this test can crash ovs-vswitchd due to a use-after-free bug on tun_table. These are the timed sequence of how this bug is triggered: - Adds an

I think you may have accidentally re-sent v1 patches with v2's commit message. The LB protocol is still not in the new flow's match, and the `ovn-sbctl dump-flows` command is still in the test. On 3/26/20 10:35 AM, num...@ovn.org wrote: From: Numan Siddique Suppose there is below NAT entry w
