    These non-security issues were fixed in tcpdump:

    - PPKI to Router Protocol: Fix Segmentation Faults and other problems
    - RPKI to Router Protocol: print strings with fn_printn()

    - nflog, mobile, forces, pptp, AODV, AHCP, IPv6, OSPFv4, RPL, DHCPv6
    enhancements/fixes
    - M3UA decode added.
    - Added bittok2str().
    - A number of unaligned access faults fixed
    - The -A flag does not consider CR to be printable anymore
    - fx.lebail took over coverity baby sitting
    - Default snapshot size increased to 256K for accomodate USB captures

    These non-security issues were fixed in libpcap:

    - Provide a -devel-static subpackage that contains the static libraries
    and all the extra dependencies which are not needed for dynamic linking.
    - Fix handling of packet count in the TPACKET_V3 inner loop
    - Filter out duplicate looped back CAN frames.
    - Fix the handling of loopback filters for IPv6 packets.
    - Add a link-layer header type for RDS (IEC 62106) groups.
    - Handle all CAN captures with pcap-linux.c, in cooked mode.
    - Removes the need for the "host-endian" link-layer header type.
    - Have separate DLTs for big-endian and host-endian SocketCAN headers.
    - Properly check for sock_recv() errors.
    - Re-impose some of Winsock's limitations on sock_recv().
    - Replace sprintf() with pcap_snprintf().
    - Fix signature of pcap_stats_ex_remote().
    - Have rpcap_remoteact_getsock() return a SOCKET and supply an "is active"
    flag.
    - Clean up {DAG, Septel, Myricom SNF}-only builds.
    - pcap_create_interface() needs the interface name on Linux.
    - Clean up hardware time stamp support: the "any" device does not support
    any time stamp types.
    - Recognize 802.1ad nested VLAN tag in vlan filter.
    - Support for filtering Geneve encapsulated packets.
    - Fix handling of zones for BPF on Solaris
    - Added bpf_filter1() with extensions
    - EBUSY can now be returned by SNFv3 code.
    - Don't crash on filters testing a non-existent link-layer type field.
    - Fix sending in non-blocking mode on Linux with memory-mapped capture.
    - Fix timestamps when reading pcap-ng files on big-endian machines.
    - Fixes for byte order issues with NFLOG captures
    - Handle using cooked mode for DLT_NETLINK in activate_new().
