| | | | | | | | | | | | | | | | o inline an ugly and potentially risky macro of the form: #define x if (a) b; else o fix a >21 y.o. bug resulting from someone writing: puts("[nothing to parse], stdout"); when they meant: fputs("[nothing to parse]", stdout); ok canacar@

* Replace <sys/param.h> with <limits.h> and other less dirty headers wherederaadt2015-01-161-2/+1
| | | | | | | | | 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@
* Let tcpdump detect bad ICMPv6 checksums with the -v flag.lteo2014-01-111-1/+42

* These two programs got fooled by the KAME/NRL split and need type repair.deraadt2013-10-241-4/+4
| | | | | | They do not indicate a problem with the reduction of namespace export, but got suckered into the 1999 plan. ok benno

| | | | | | | unmaintainable). these days, people use source. these id's do not provide any benefit, and do hurt the small install media (the 33,000 line diff is essentially mechanical) ok with the idea millert, ok dms
