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.
