This diff modifies the system resolver to use a getaddrinf transport. Obviously the transport is a fake, but its existence will allow us to observe DNS events more naturally. A lookup using the system resolver would be a ANY lookup that will contain all the resolved IP addresses into the same response. This change was also part of websteps-illustrated, albeit the way in which I did it there was less clean than what we have here. Ref issue: https://github.com/ooni/probe/issues/2096 |

Package github.com/ooni/probe-engine/netx
OONI extensions to the net and net/http packages. This code is
used by ooni/probe-engine as a low level library to collect
network, DNS, and HTTP events occurring during OONI measurements.
This library contains replacements for commonly used standard library interfaces that facilitate seamless network measurements. By using such replacements, as opposed to standard library interfaces, we can:
- save the timing of HTTP events (e.g. received response headers)
- save the timing and result of every Connect, Read, Write, Close operation
- save the timing and result of the TLS handshake (including certificates)
By default, this library uses the system resolver. In addition, it is possible to configure alternative DNS transports and remote servers. We support DNS over UDP, DNS over TCP, DNS over TLS (DoT), and DNS over HTTPS (DoH). When using an alternative transport, we are also able to intercept and save DNS messages, as well as any other interaction with the remote server (e.g., the result of the TLS handshake for DoT and DoH).
This package is a fork of github.com/ooni/netx.
