[SECURITY] Fedora 24 Update: libreswan-3.17-1.fc24

Libreswan is a free implementation of IPsec & IKE for Linux. IPsec is the Internet Protocol Security and uses strong cryptography to provide both authentication and encryption services. These services allow you to build secure tunnels through untrusted networks. Everything passing through the untrusted net is encrypted by the ipsec gateway machine and decrypted by the gateway at the other end of the tunnel. The resulting tunnel is a virtual private network or VPN. This package contains the daemons and userland tools for setting up Libreswan. To build KLIPS, see the kmod-libreswan.spec file. Libreswan also supports IKEv2 (RFC4309) and Secure Labeling Libreswan is based on Openswan-2.6.38 which in turn is based on FreeS/WAN-2 .04
