104e8393f3 lib/fetch: fix happy eyeballs without any usable addresses and catch more errors 2019-06-15 19:19:40 +02:00

0c657582f2 lib/fetch/common.c: send socks5 request as a single transaction
Splitting the socks5 request is causing issues when running against Tor.
It causes Tor to fail with an address unknown error. Assembling the
request and sending it in its entirety solves the issue.

An strace of torsocks, that functions correctly when used with xbps, shows
that the request is being sent all at once:

        recvfrom(3, "\5\0", 2, 0, NULL, NULL)
        sendto(3, "\5\1\0\3>lysator7eknrfl47rlyxvgeamrv7ucefgrrlhk7rouv3sna25asetwid.onion\0P", 69, 0, NULL, 0)
        recvfrom(3, "\5\0\0\1\0\0\0\0\0\0", 10, 0, NULL, NULL)

Closes: #54 [via git-merge-pr]

9f52a7837f lib/fetch: add happy eyeballs connect algorithm (RFC6555/RFC8305)
Connect to the addresses from `getaddrinfo(3)`,
alternating between address family,
starting with ipv6 and wait `fetchConnDelay`
between each connection attempt.

If a connection is established within the attempts,
use this connection and close all others.

If `connect(3)` returns `ENETUNREACH`, don't attempt more
connections with the failing address family.

If there are no more addresses to attempt,
wait for `fetchConnTimeout` and return the first established
connection.

If no connection was established within the timeouts,
close all sockets and return -1 and set errno to
`ETIMEDOUT`.

f4cb178f6c libfetch: use default CA path rather than default CA file.
The default CA file set by FreeBSD is only available when using the
LibreSSL provided CA file, and we've decided to use the CA path
by default.

Discussed with @dominikh.

7aebea684b Implemented support for working with remote repositories.
libfetch from NetBSD's pkgsrc has been imported into lib/fetch, but
the objects are embedded into libxbps. Only a public function to fetch
files has been implemented: xbps_fetch_file().

The library now is built with -fvisibility=hidden by default, and
exported symbols are the ones that use the SYMEXPORT macro.

The code works well enough, but will need many more cleanups.
