2022-03-18cnat: Fix conflicting rsessionNathan Skrzypczak1-2/+33
When dNAT-ing to a VIP, it can happen that the return session conflicts with another forward session than the one we own. This patchs adds a rsession_flags CNAT_SESSION_RETRY_SNAT that makes cnat_session_create search for a free src port to use for the resulting return session. It also makes forward & return session share their fate in the session scanner.
