* - (void)printf() -> printf(); the cast adds clutter for little value.procter2020-01-241-9/+9
| | | | | | | | | | - 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
* Replace <sys/param.h> with <limits.h> and other less dirty headers wherederaadt2015-01-161-4/+4
| | | | | | | | | 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)

* Instead of showing the difference between a bad checksum and a goodlteo2014-06-201-5/+8
| | | | | | | | | | | | | | checksum, make tcpdump (with the -v flag) show the actual bad checksum within the IP/protocol header itself and what the good checksum should be, e.g. "[bad tcp cksum abcd! -> d1e6]" This change applies to IP, TCP (over IPv4 and IPv6), UDP (over IPv4 and IPv6), ICMP, and ICMPv6. This commit also fixes several inconsistencies in the way bad checksums were displayed for these protocols. Tested on amd64, i386, and macppc. ok henning@

* Make icmp_print() accept the length variable, which is the length of thelteo2014-01-111-2/+2
| | | | | | | | | | | | | 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. OK florian@
