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() - Added a short option '#', same as long option '--number' - 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().
