2022-03-18cnat: Fix conflicting rsessionNathan Skrzypczak1-0/+5
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.

2021-01-28cnat: Fix session with deleted trNathan Skrzypczak1-1/+1
Type: fix When a translation gets deleted, hiting a session pointing to it sefaults. We're better off directly storing the next node index. Change-Id: I4f0716d775202b4ecf54d6cdb827bbeebd23056c Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com>

Type: fix When using sNAT in combination with cnat translations it might happen that the cnat_node_vip.c picks up a translation on a session that has an invalid lb index, thus resulting in a later crash in ip4-load-balance Change-Id: I82607086b2d672a9dcf26bfb82ad7f83e6474562 Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com>
