December 30, 2010 by mcr, Denis, and FXL Summary for 4.99.0 tcpdump release Improve the contents, wording and formatting of the man page. Print unsupported link-layer protocol packets in hex. Add support for new network protocols and DLTs: Arista, Autosar SOME/IP, Broadcom LI and Ethernet switches tag, IEEE 802.15.9, IP-over-InfiniBand (IPoIB), Linux SLL2, Linux vsockmon, MACsec, Marvell Distributed Switch Architecture, OpenFlow 1.3, Precision Time Protocol (PTP), SSH, WHOIS, ZigBee Encapsulation Protocol (ZEP). Make protocol-specific updates for: AH, DHCP, DNS, ESP, FRF.16, HNCP, ICMP6, IEEE 802.15.4, IPv6, IS-IS, Linux SLL, LLDP, LSP ping, MPTCP, NFS, NSH, NTP, OSPF, OSPF6, PGM, PIM, PPTP, RADIUS, RSVP, Rx, SMB, UDLD, VXLAN-GPE. User interface: Make SLL2 the default for Linux "any" pseudo-device. Add --micro and --nano shorthands. Add --count to print a counter only instead of decoding. Add --print, to cause packet printing even with -w. Add support for remote capture if libpcap supports it. Display the "wireless" flag and connection status. Flush the output packet buffer on a SIGUSR2. Add the snapshot length to the "reading from file ..." message. Fix local time printing (DST offset in timestamps). Allow -C arguments > 2^31-1 GB if they can fit into a long. Handle very large -f files by rejecting them. Report periodic stats only when safe to do so. Print the number of packets captured only as often as necessary. With no -s, or with -s 0, don't specify the snapshot length with newer versions of libpcap. Improve version and usage message printing. Building and testing: Install into bindir, not sbindir. autoconf: replace --with-system-libpcap with --disable-local-libpcap. Require the compiler to support C99. Better detect and use various C compilers and their features. Add CMake as the second build system. Make out-of-tree builds more reliable. Use pkg-config to detect libpcap if available. Improve Windows support. Add more tests and improve the scripts that run them. Test both with "normal" and "x87" floating-point. Eliminate dependency on libdnet. FreeBSD: Print a proper error message about monitor mode VAP. Use libcasper if available. Fix failure to capture on RDMA device. Include the correct capsicum header. Source code: Start the transition to longjmp() for packet truncation handling. Introduce new helper functions, including GET_*(), nd_print_protocol(), nd_print_invalid(), nd_print_trunc(), nd_trunc_longjmp() and others. Put integer signedness right in many cases. Introduce nd_uint*, nd_mac_addr, nd_ipv4 and nd_ipv6 types to fix alignment issues, especially on SPARC. Fix many C compiler, Coverity, UBSan and cppcheck warnings. Fix issues detected with AddressSanitizer. Remove many workarounds for older compilers and OSes. Add a sanity check on packet header length. Add and remove plenty of bounds checks. Clean up pcap_findalldevs() call to find the first interface. Use a short timeout, rather than immediate mode, for text output. Handle DLT_ENC files *not* written on the same OS and byte-order host. Add, and use, macros to do locale-independent case mapping. Use a table instead of getprotobynumber(). Get rid of ND_UNALIGNED and ND_TCHECK(). Make roundup2() generally available. Resync SMI list against Wireshark. Fix many typos.
