      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.

      Fix file descriptor leaks · 9fab68ee
      Julien Muchembled authored
      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.

      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.

      Switch to OpenVPN 2.4 · 06974788
      Killian Lufau authored
      The behaviour of --link-mtu has changed and we increase the values to
      at least have interface MTU greater than IPv6 minimum.
      We'll see later to have even greater values in ovpn_link_mtu_dict
      (so that the resulting MTU is closer to what we had with 2.3)
      or review the whole MTU part completely.
