Revision 07998281c268592963e1cd623fe6ab0270b65ae4 authored by Florian Westphal on 05 February 2021, 11:56:43 UTC, committed by Pablo Neira Ayuso on 08 February 2021, 23:04:14 UTC
The origin skip check needs to re-test the zone. Else, we might skip
a colliding tuple in the reply direction.
This only occurs when using 'directional zones' where origin tuples
reside in different zones but the reply tuples share the same zone.
This causes the new conntrack entry to be dropped at confirmation time
because NAT clash resolution was elided.
