- Add IPv6 router dispatch to AddOutputDNAT/RemoveOutputDNAT in both
nftables and iptables managers (was hardcoded to v4 router only).
- Fix all DNAT and AddDNATRule dispatch methods to check Is6() first,
then error with ErrIPv6NotInitialized if v6 components are missing.
Previously the hasIPv6() && Is6() pattern silently fell through to
the v4 router for v6 addresses when v6 was not initialized.
- Add ErrIPv6NotInitialized sentinel error, replace all ad-hoc
"IPv6 not initialized" format strings across both managers.
- Rename sourcePort/targetPort to originalPort/translatedPort in all
DNAT method signatures to reflect actual DNAT semantics.
- Remove stale "localAddr must be IPv4" comments from interface.
* Add DNS list argument for mobile client
* Write testable code
Many places are checked the wgInterface != nil condition.
It is doing it just because to avoid the real wgInterface creation for tests.
Instead of this involve a wgInterface interface what is moc-able.
* Refactor the DNS server internal code structure
With the fake resolver has been involved several
if-else statement and generated some unused
variables to distinguish the listener and fake
resolver solutions at running time. With this
commit the fake resolver and listener based
solution has been moved into two separated
structure. Name of this layer is the 'service'.
With this modification the unit test looks
simpler and open the option to add new logic for
the permanent DNS service usage for mobile
systems.
* Remove is running check in test
We can not ensure the state well so remove this
check. The test will fail if the server is not
running well.
