[ upstream commit 07d376e ] When the SNAT entry already exists for a connection that goes through the egress gateway (i.e. it's not the first packet), ct_lookup4 is skipped. That means that ct_update_timeout is not called, and the CT entry will be garbage collected while the connection is still active. To fix this bug, do the CT lookups for the second and further packets of connections using egress gateway as well. Fixes: 4532996 ("bpf: nat: always track egress gateway connections") Signed-off-by: Maxim Mikityanskiy <maxim@isovalent.com>
