Hi Dumitru, just a small nit below On 2/4/21 8:25 AM, Dumitru Ceara wrote:
Caching the conjunction id offset for flows that refer to address sets and/or port groups but do not currently generate conjunctive matches, e.g., because the port group has only one locally bound port, is wrong.If ports are later added to the port group and/or addresses are added to the address set, this flow will be reconsidered but at this point will generate conjunctive matches. We cannot use the cached conjunction id offset because it might create collisions with other conjunction ids created for unrelated flows. Fixes: 1213bc827040 ("ovn-controller: Cache logical flow expr matches.")
