      Fix TypeError in _updateCountry · ecda9f06
      Joanne Hugé authored
      Addresses passed to _updateCountry can contain countries if
      cache.my_address is used to initialize address in BaseTunnelManager init
      function, which causes resolve to be called with too many arguments.

      Fix two issues related to handleHello · bbde1c0d
      Joanne Hugé authored
      In some circumstances, the hello_protocol attribute could get modified
      on the wrong peer, which would raise an AttributeError.
      On reception of seqno 1 from a peer with protocol < 7, protocol could be
      equal to zero which would cause handleHello to not return True, causing
      the handshake to fail.

      New --country option; add country in addresses · 85d77bd8
      Joanne Hugé authored
      This commit concerns networks that use the --same-country option.
      We recently discovered that the IP geolocation database contains
      incorrect entries. To work around this, the protocol needs to be
      changed by adding the country as 4th field in addresses (the first 3
      are: ip, port, protocol) and the new --country option allows a node
      to announce a country that differs from the one the GeoIP DB.
      Thanks to the previous commits it's possible to implement backward
      compatibility, by not sending the 4th field (country) to nodes that
      can't parse it. Of course, these old nodes would continue to not
      create appropriate tunnels and after a while, the administrator of
      the network may decide to increase registry's --min-protocol (7).
      In a network with only nodes that implement this last version of the
      protocol, the nodes may only use the GeoIP DB to resolve their own IPs.

      Add protocol to handshake between nodes · 4f327e1b
      Julien Muchembled authored
      There is a need to be able to extend the protocol without breaking
      compatibility with old nodes. This is done by sending version.protocol
      during inter-node handshake, in seqno 1 and seqno 2, so that a node
      knows what version the peers speak and use appropriate format.
      This is implemented with partial backward compatibility: handshake with
      an old node succeeds when the new node does not have to send seqno 1.

      This should fix strange bugs after running the demo for a long time,
      with certificate renewal happening every few minutes.

      Remove --ipv6, reuse --ip instead · 343e910a
      Julien Muchembled authored
      The previous commit, which adds --ipv6, has the issue
      that it does not check whether given IPs are valid.
      Since IPv4 & IPv6 use completely different address
      representation, --ip can be used for both.

      New --ipv6 option and fix learning of external IPv6 from other peers · 0106e2f9
      Julien Muchembled authored
      When re6st attempts to use UPnP and IPv6 is enabled at the same time,
      the external IPv4 was published for IPv6 protocols.
      For example, machine6 in the demo had:,1194,tcp;,1194,udp;,1195,udp6
      This caused re6stnet to crash (socket.gaierror) if GEOIP2_MMDB is set.
      With this commit, IPv4 & IPv6 are now processed independently.

      Fix handling of private methods · d0233199
      Killian Lufau authored
      The detection of the attribute `_private` was performed on a string
      object representing the name of the method instead of the method itself,
      leading to the registry allowing anyone to call private methods.

      demo: add another re6st network · d868f09a
      Killian Lufau authored
      The purpose is to check that HMAC prevents routes from being exchanged
      between the 2 networks. This happened when 2 nodes of 2 different re6st
      networks are in the same LAN, and it caused many issues.

      Implement HMAC for babel · 12ba2ee4
      Killian Lufau authored
      HMAC is added in babel call to prevent babel communication between nodes of different re6st networks. 
      This solves the problem of machines in different re6st networks but on the same LAN that exchange routes through babel. 
      The key used to authenticate packets is randomly created on 16 bytes by the registry and sent to nodes when they fetch network parameters. 
      This uses the WIP hmac branch of jech/babeld with Nexedi patches and the added possibility to not check HMAC in incoming packets for better HMAC integration on a HMAC-less network.

      Fix --disable-proto · 120fff13
      Killian Lufau authored
      argparse is error-prone in that `action='append'` starts from (a copy of) the
      given default when it adds values from command-line, rather than restarting
      from an empty list. For example, simply passing `--disable-proto udp` resulted
      in ['udp', 'udp6', 'udp'], which caused 'udp6' to remain disabled.

      OpenVPN 2.4.7 workaround to revert to previous MTU settings · d398aa93
      Killian Lufau authored
      In commit 06974788,
      we increased the --link-mtu value as a temporary way to compensate the
      unexplained behaviour change of recent OpenVPN.
      This was partly due to encryption, which was enabled despite
      `--cipher none`. And it happens that the behaviour of --link-mtu only
      changed for the server, with a mysterious difference of 93 bytes.
      Hence the workaround to get identical tunnel MTU on both sides.

      Remove old fix in ovpn-client · 24fea8cd
      Killian Lufau authored
      The fix to mark an interface as "up" and indicate its MTU was
      useful for machines with a single client, because OpenVPN would fail
      to configure them this way in OpenVPN 2.3. It has been fixed in 2.4
      so the fix has been removed.
