Hummingbird 1.0.3 released

Recommended Posts

Hello!


We're glad to inform you that Hummingbird 1.0.3 has just been released.

Hummingbird is a free and open source software by AirVPN for:

  • Linux x86-64
  • Linux ARM 32 (example: Raspbian for Raspberry Pi)
  • Linux ARM 64
  • macOS (Mojave or higher version required) - please do not miss important notes on macOS below

based on OpenVPN3-AirVPN 3.6.4 library supporting CHACHA20-POLY1305 cipher on OpenVPN Data Channel and Control Channel. Hummingbird is very fast and has a tiny RAM footprint. AES-CBC and AES-GCM are supported as well.

Version 1.0.3 uses OpenVPN3-AirVPN 3.6.4 library which had major modifications:

  • IPv6 compatibility has been improved
  • override logic has been improved
  • a critical bug related to a main branch regression for TCP connections has been fixed


Important: if you build Hummingbird please make sure to align to AirVPN library 3.6.4. You can't build Hummigbird 1.0.3 with library versions older than 3.6.4.

Hummingbird is not aimed to Android but you can have CHACHA20-POLY1305 on Android too: please run our software Eddie Android edition, which uses our OpenVPN3-AirVPN library.
 

 

Important notes for macOS users

From now on we provide both a notarized version and a non-notarized version of Hummingbird for macOS. The notarized version is available essentially for those users who required it, but it is not recommended.

The notarized version will run without blocks by Apple's Gatekeeper, but will let Apple correlate your real IP address, Apple ID and other data potentially disclosing your identity to the fact that you run, and when you did it for the first time, an application by AirVPN.

If that's not acceptable for you, just download the tarball package .tar.gz (it is NOT notarized and NOT signed with our Apple developer ID on purpose) and include it in the exceptions to run non-notarized programs.

In the future that could be no more allowed, but at the moment it is. For a more thorough explanations on important privacy issues caused by Apple and notarization please see for example here https://lapcatsoftware.com/articles/notarization-privacy.html and here https://lapcatsoftware.com/articles/catalina-executables.html
 

Notes for Linux users

  • x86-64 version requires a reasonably recent distribution (at least on par with Debian 9 kernel and libraries) based on systemd. A version compatible with SysVInit is anyway planned
  • armv7l version (32 bit) has been tested in Raspberry Pi 3 and 4 with Raspbian 10. It will not run in Raspbian 9 (libraries are too old)
  • aarch64 version (for 64 bit ARM) has been tested in Raspberry Pi4 with Ubuntu 19 and Ubuntu 20 for ARM 64 bit
     


TCP queue limit

If you connect over TCP, Hummingbird will set by default a minimum TCP outgoing queue size of 512 packets to avoid TCP_OVERFLOW errors. If you need a larger queue in TCP, the following option is now available from command line, in addition to profile directive tcp-queue-limit:
 

--tcp-queue-limit n


where n is the amount of packets. Legal range is 1-65535.

We strongly recommend you to allow at least 512 packets as queue limit (default value). Larger queues are necessary when you connect in TCP and need a lot of open connections with sustained (continuous) but not necessarily high throughput, for example if you run a BitTorrent software. In such cases you can enlarge the queue as much as you need, until you stop getting TCP_OVERFLOW.

It's not uncommon from our community as well as our internal tests to set 4000 packets queue limit to prevent any TCP overflow.


If you connect over UDP, you can ignore all of the above.
 


Network Lock

Network Lock prevents traffic leaks outside the VPN tunnel through firewall rules. Hummingbird 1.0.3 widens --network-lock option arguments. The following arguments are now accepted:
on  | off  | iptables | nftables | pf  (default: on).

If you specify on argument, or you omit --network-lock option, Hummingbird will automatically detect and use the infrastructure available on your system. Hummingbird picks the first available infrastructure between iptables-legacy, iptables, nftables and pf.



Note: command line options, when specified, override profile directives, when options and profile directives have the same purpose.

OpenVPN3-AirVPN library Changelog

Changelog 3.6.4 AirVPN - Release date: 23 May 2020 by ProMIND

- [ProMIND] [2020/05/23] completely changed the logics controlling overrides (server, port and protocol)
                         client/ovpncli.cpp: parse_config() Properly assigned serverOverride, portOverride and protoOverride to eval.remoteList
                         client/ovpncli.cpp: parse_config() In case serverOverride is set, remoteList is cleared and recreated with just one item containing serverOverride
                         client/ovpncli.cpp: parse_config() In case portOverride or protoOverride is set, all the items in remoteList are changed accordingly
                         openvpn/client/remotelist.hpp: Added public method set_transport_protocol_override() to assign the override protocol to all items in remoteList
                         openvpn/client/cliopt.hpp: ClientOptions() now calls remote_list->set_transport_protocol_override() instead of remote_list->handle_proto_override()

Hello, I have just had a weird behavior while connected with hummingbird.
I have 2 devices connected at the moment and I was working in one of them doing some tests on a script I'm working on using AirVPN's userinfo API.
The thing is that suddenly the script was showing a single session and the one missing was the one of the computer I was using.
My connection however was working fine through the VPN (ipleak also detected it fine). but the API didn't seem to recognize it.
The hummingbird logs showed some ERROR messages while the anomaly was happening and after a while everything came back to normal.

Here are the logs:

Hi,

I am running Hummingbird on my Raspberry Pi 2 (Raspbian Buster) and I am having somehow unexpected results.

The Pi is connected by cable and without VPN I get around 10/11 MB/s the usual speed for this device. With the OpenVPN version I have installed (2.4.7) I see speeds around ~4/5 MB/s.
I tried this version of Hummingbird and for my surprise the speed drops to a constant low of ~ 1MB/s. I've used the experimental servers where the CHACHA cypher is allowed, but I couldn't see an improvement quite the opposite.

Does someone have some tips to improve this?

Thanks in advance.

This version of hummingbird is proving much more stable for me on my Linux x86-64 systems running Slackware, exhibiting (so far) none of the key negotiation errors that plagued my UDPv4 usage of earlier versions.
Thanks for the good work.  Once things have been straightened out with IPv6 connections I'll ditch OpenVPN2.
