Description

When I drop the VPN connection with Ctrl-c (SIGINT), the client closes well but a hang occurs.

I reproduce the bug very easily by reproducing these steps:

  1. Launch OpenVPN client
  2. Launch firefox
  3. Open a Youtube video
  4. Wait a few seconds
  5. Close the vpn client with Ctrl-c

The bug seems to be the same as http://ubuntuforums.org/showthread.php?t=2121225

I use ArchLinux? x86_64 and dmesg, journalctl, gdb does not provide information about this bug.

$ uname -a

Linux SaggahArch 3.18.6-1-ARCH #1 SMP PREEMPT Sat Feb 7 08:44:05 CET 2015 x86_64 GNU/Linux

I'm afraid that this is a Linux bug, not OpenVPN - I assume it has to do with firewalling, connection tracking, and "something getting confused" when the tun interface goes away, but this needs to be fixed on the kernel side, nothing we can do in OpenVPN here.

I'm closing this as "outside of OpenVPN".

Please feel free to reopen if it turns out there is anything that needs to be done in OpenVPN.
