      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.

      Fix deactivation of encryption with recent OpenVPN · 114a1763
      Killian Lufau authored
      Passing `--cipher none` to OpenVPN is not enough anymore because
      clients and servers can still negotiate the algorithm to use for
      encryption (by default not empty). We pass the option `--ncp-disable`
      to disable cipher negotiation.

      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.

      Log signals that are sent to kill subprocesses and increase default log level · 9e6ece7a
      Julien Muchembled authored
      We currently have issues with OpenVPN hook scripts that aren't always killed
      at exit. Such orphan processes prevent re6st from starting again (EADDRINUSE).
      
      We want to know if it's an OpenVPN that does not exit cleanly on TERM,
      or if it sometimes does not exit at all after 5s (then re6st sends a KILL
      signal and at that point we should indeed make sure that any subprocess is
      also KILLed).
