Description

As reported on https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=895903:

Tor now returns IPv6 addresses when hostnames are resolved, but torsocks cannot handle this case.

To reproduce:

torsocks -d nc v6.ipv6-test.com 80


This makes it tricky to use torsocks on domains that will resolve to an AAAA only causing the program to abort with no error message.

Indeed, in

int socks5_send_resolve_request(const char *hostname, struct connection *conn)

I see:

/* By default we use IPv4 address. */
msg.atyp = SOCKS5_ATYP_DOMAIN;

(I've tested it from the command line with torsocks 2.3.0, and it does not work, while using TBB it works fine.)

I'm not sure if this issue is also related to this bug:
