(1) Reject zero-length strings for CTLTYPE_INT, _UINT, _LONG, _ULONG. Do not silently convert to 0. (2) When converting CTLTYPE_INT, _UINT, _LONG, and _ULONG, check the end pointer generated by strtol() and strtoul() rather than discarding it. Reject the string if either none of the string was useful for conversion to an integer, or if there was trailing garbage. I.e., we will not allow you to set a numeric sysctl to a value unless we can completely convert the string argument to a numeric value. I tripped over this when I put the following in /etc/sysctl.conf: kern.maxfiles="4000" Ouch. |
