- (void)printf() -> printf(); the cast adds clutter for little value. - fprintf(stdout, ...) -> printf() - fputs(x, stdout) -> printf(); for consistency. fputs is twice as fast on atom x5-Z8300@1.44GHz but Amdahl sees a pure printf tcpdump only 2% slower than a pure fputs (for constant strings) tcpdump to /dev/null across a 20MB/~170k packet pcap file. ok dlg@ for fputs and ok tedu@ krw@ deraadt@ a2k19 for the rest

Remove #ifdef INET6 There's not reason to build without IPv6 support, `-U INET6' builds were broken anyway. Fix an empty redefine for IPPROTO_IPV6 in print-ip.c while here. No object change on amd64 and sparc64 with clang, gcc compiles differently but behaviour stays the same. OK denis deraadt

Rework UDP parsing, particularly around IP addresses. This originally started as trying to put a consistent space between the UDP header information and the payload parsing, but while doing that I noticed inconsistent IPv4 vs IPv6 handling. Apart from the default "srcip.srcport > dstip.dstpor" output, all the other places that IP addresses were printed assumed IPv4. It looks like it is possible that udp_print() can be called without an IP header, which made these blind IPv4 prints turn into NULL derefs. This fixes the problem above by only having a single place that prints the addresses out, and makes sure to get the difference between IPv4, IPv6 and no IP correct. This changes how the checksum is calculated. It incrementally builds the UDP checksum by feeding the IPv4 and v6 addresses in separately, then using common code for the rest of the pseudo header and actual payload. Lastly, this does make printing the space between the UDP header and its payload consistent. The UDP code is now responsible for adding a space after itself so the payload parsers don't have to. They got it wrong in some cases anyway, so this should be a lot more uniform. help and ok sthen@

Replace <sys/param.h> with <limits.h> and other less dirty headers where possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)

Make icmp_print() accept the length variable, which is the length of the
packet without the IP header. This is needed by the next commit that
will allow tcpdump to detect bad ICMP checksums.
Related functions like {tcp,udp,icmp6}_print() already accept this
length variable, so this change makes icmp_print() consistent with
them as well.
This commit makes no functional change to tcpdump itself.
