Hello again,<br><br>my Christmas present to you: the promised info neccessary to recreate the deadlock.<br><br>Setup: host A (192.168.1.134) - host B (192.168.1.135)<br><br>Installed strongSwan on both host using:<br>wget <a href="http://download.strongswan.org/strongswan-4.5.3.tar.bz2">http://download.strongswan.org/strongswan-4.5.3.tar.bz2</a><br>
tar -xvf strongswan-4.5.3.tar.bz2<br>cd strongswan-4.5.3.tar.bz2<br>./configure --enable-openssl<br>make<br>sudo make install<br><br>Certs, config etc included per host in attached tar file. Taken from /usr/local/<br>running the attached script from host A should recreate deadlock. Note that the script restarts strongSwan on both ends and start connections. It assumes non-blocking root access. I.e. authorized keys have been set up, and that the script was run as root (to be able to start a connection using ipsec command).<br>
<br>In my case it deadlocks at confidence_run 2. Note that the actual confidence run identifier (integer) is used as seed in the calculation of exponentially divided inter-arrival time of the initiated connections, see gsl-randist command in the script. And that other parameters set in the script influence also impact on actual generated inter-arrival time.<br>
<br>Please let me know if I can assist any further on this matter.<br><br>Merry Christmas,<br><br>Jan Willem<br><br><div class="gmail_quote">2011/12/24 Jan Willem Beusink <span dir="ltr"><<a href="mailto:beusink@gmail.com">beusink@gmail.com</a>></span><br>

<br>
I'll send you the complete configs, certs, scripts, etc, to reproduce the bug in a few days.<br>
I now can confirm however, that the bug occurs in a vanilla build (4.5.3) using only --enable-openssl.<br>
<br>
I'll send you the requested info as soon as I have time.<br>
<br>
Regards,<br>
