* 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.

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)

* warnx?/errx? paranoia (use "%s" not a bare string unless it is amillert2000-06-301-3/+3
| | | | | | | | | constant). These are not security holes but it is worth fixing them anyway both for robustness and so folks looking for examples in the tree are not misled into doing something potentially dangerous. Furthermore, it is a bad idea to assume that pathnames will not include '%' in them and that error routines don't return strings with '%' in them (especially in light of the possibility of locales).
* Only exit in nlist.c due to a memory error, otherwise just return. A return value of 1 indicates an incorrect executable type, a return value of -1 indicates some other problem. This gives us better fallback from /dev/ksyms to /bsd.millert1999-03-241-61/+91

| | | | | | | | | | | 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
