improve IPv6 support

[ethanmdavidson]

Rationale

My ISP uses carrier-grade NAT which means I do not have an IPv4 address to use. However, my device has an IPv6 address. I have been told that golem should work properly over IPv6, but that I will likely only be able to connect to peers that have also enabled IPv6. Also, despite the fact that my IPv4 connection isn't working properly, the client continues to try to connect to IPv4 addresses.

Description

Suggestions:

• enable IPv6 by default.
• allow IPv4 to be disabled.

A more elegant solution might be to have the client autodetect which stack to use, e.g. try to connect to IPv4 and IPv6 when client is first started, but if all connections from one stack are failing, disable that stack.

User Interface

Are user-facing changes required for this functionality?

• Despite my IPv6 connection working properly, the gui still reports "problem with ports". This check should be reworked to display the status of both stacks.

Technical specification

According to golem team members, "IPv6 is supported in the network module, but there may be problems on the way (with display, further checks, ports etc.)"

QA

Description of the QA process for the feature

Test scenarios:

Base test process

specify one of: ( if unsure, consult @ZmijaWA or @ederenn ) ** QA limited to the single feature (in case of very trivial changes) ** Smoke Test (the limited set of tests designed to ensure that most critical functionality doesn't experience regressions) ** Full Test (full set of tests for the whole application - in case of more extensive application updates, refactoring etc)

New feature tests

Add test scenarios for the new feature

Positive Scenario 1

• Step 1
• Step 2
• ...
• Expected results

Positive Scenario 2

• ...

Negative Scenario 1

• Step 1
• Step 2
• ...
• Some expected problem
• Expected problem handling

Possible regressions

• is there any functionality that is likely to experience regressions?
• are there any existing application components that should be tested more thoroughly?
