Merge remote-tracking branch 'goog/tcpdump' * goog/tcpdump: (3066 commits) Remove old version. Getting ready for new tcpdump 4.5 Support -Q for setting the capture direction. Clean up the TLV processing loop. With -A and -AA, don't send CRs to the standard output. Use the new libpcap <pcap/nflog.h> for NFLOG definitions and declarations. Do our own isascii(), isprint(), isgraph(), and toascii(). Fix a compiler warning. Don't use the __attribute__((packed)) on most platforms. The interval in an AODV HELLO extension is not aligned on a 4-byte boundary. As with memcpy, so with memcmp. More UNALIGNED_MEM{CPY,CMP} on IP addresses. Another case where UNALIGNED_MEMCPY() is probably necessary. No need for casting back and forth. Only do the unaligned_mem{cpy,cmp} hack if necessary. No need to declare unaligned_mem{cpy,cmp} in netdissect.h *and* interface.h. More possibly-unaligned memcpy()s and assignments - use unaligned_memcpy(). Check for compiling for IPv6; don't check whether we can create an IPv6 socket. Use unaligned_memcmp() to compare with IPv{4,6} addresses in a packet. Use EXTRACT_nBITS even when just testing against zero. Fix some more unaligned accesses. ... Change-Id: I9e98707d30c989b9e32dcd5af798bd0746ab4434
