Martin Willi 5b15bd5f9d Set configured DSCP value while generating IKE packets 2013-02-06 15:20:32 +01:00
Tobias Brunner 2ec3552fce Fix check-in of IKE_SA when IKE_SA_INIT fails and hash table is enabled 
Setting the responder SPI to 0 can only be done while generating the
response, otherwise we'd fail to check in the IKE_SA again in case the
hash table is enabled.  That's because we use the responder SPI as hash
value since 5.0.0.
