After upgrade from 5.3.3 to 5.3.4 only one connection is possible, charon: 00[DMN] waiting for signal failed: Interrupted system call
Just upgraded from 5.3.3 where everything was working to 5.3.4. Now after one connection (which is successful) no other connections are possible.
Noticed this log line which only appears using 5.3.4:
Nov 20 08:19:20 ip-172-31-20-201 charon: 00[DMN] waiting for signal failed: Interrupted system call
ipsec statusall shows no output after the successful connection, if you try to reinitiate a connection with ipsec up conn it exits with exitcode 7.
The config was not changed after upgrade. Packages were build on Ubuntu 14.04.3 LTS exactly the same way as 5.3.3 which works.
Installed packages are:
ii libstrongswan 5.3.4-0-2scale amd64 strongSwan utility and crypto library ii strongswan 5.3.4-0-2scale all IPsec VPN solution metapackage ii strongswan-ike 5.3.4-0-2scale amd64 strongSwan Internet Key Exchange (v2) daemon ii strongswan-plugin-eap-radius 5.3.4-0-2scale amd64 strongSwan plugin for EAP interface to a RADIUS server ii strongswan-plugin-openssl 5.3.4-0-2scale amd64 strongSwan plugin for OpenSSL ii strongswan-plugin-xauth-generic 5.3.4-0-2scale amd64 strongSwan plugin for the generic XAuth backend ii strongswan-starter 5.3.4-0-2scale amd64 strongSwan daemon starter and configuration file parser
Running kernel version is 3.13.0-66-generic, version was build on this machine.
Config was not changed between 5.3.3 and 5.3.4, no differences in /etc/strongswan.d/. The only thing which is configured in /etc/strongswan.d/charon is eap-radius.conf.
