_libreswan_ rebased to version 3.15 *Libreswan* is an implementation of Internet Protocol Security (IPsec) and Internet Key Exchange (IKE) for Linux. The _libreswan_ packages have been upgraded to upstream version 3.15, which provides a number of enhancements and bug fixes over the previous version. Notable changes include the following: * The nonce size is increased to meet the RFC requirements when using the SHA2 algorithms. * *Libreswan* now calls the *NetworkManager* helper in case of a connection error. * All *CRLdistributionpoints* in a certificate are now processed. * *Libreswan* no longer tries to delete non-existing IPsec Security Associations (SAs). * The *pluto* IKE daemon now has the `CAP_DAC_READ_SEARCH` capability. * *pluto* no longer crashes when on-demand tunnels are used. * `pam_acct_mgmt` is now properly set. * The regression was fixed so tunnels with "keyingtries=0" try to establish the tunnel indefinitely. * The delay before re-establishing the deleted tunnel that is configured to remain up is now less than one second.
