netfilter: nf_conntrack: Support expectations in different zones
[ Upstream commit 4b31814d20cbe5cd4ccf18089751e77a04afe4f2 ]
When zones were originally introduced, the expectation functions were
all extended to perform lookup using the zone. However, insertion was
not modified to check the zone. This means that two expectations which
are intended to apply for different connections that have the same tuple
but exist in different zones cannot both be tracked.
Fixes: 5d0aa2ccd4 (netfilter: nf_conntrack: add support for "conntrack zones")
