* When system calls indicate an error they return -1, not some arbitraryderaadt2019-06-281-2/+2
| | | | | | value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.
* Replace <sys/param.h> with <limits.h> and other less dirty headers wherederaadt2015-01-161-2/+2
| | | | | | | | | 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)
* rcsid[] and sccsid[] and copyright[] are essentially unmaintained (andderaadt2009-10-271-9/+1
| | | | | | | 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

* Make kvm_mkdb work againmillert1998-08-191-9/+5
| | | | | | | | | | | o testdb() needs to take as an arg the name of the kernel so it can do the version test correctly. o add undocumented verbose flag to tell when we are rebuilding the .db file o DO_* -> _NLIST_DO_*, this prevented kvm_mkdb from doing anything at all. o preserve a few error messages so you get error output when none of the exec types match the target. o check malloc return values o get_kerntext should not subtract the sizeof(struct exec) from kernel_text
* From NetBSD: make testdb() fail if database version string has length zero.millert1997-01-151-8/+13
| | | | | Also, KNF, b* -> mem*, getopt tests against -1, not EOF, and index -> strchr. Added OpenBSD tags.
* initial import of NetBSD treederaadt1995-10-181-0/+114
