* Tighten up the string->integer conversion in sysctl(8):rwatson2003-06-151-5/+25
| | | | | | | | | | | | | | | | | | | (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.

* Document the existence of machdep.guessed_bootdev, as suggestedluigi2002-03-121-0/+1
| | | | | | | | | | | by Sheldon. For a detailed description look at the commit log for sysctl.c rev.1.42 -- i do not think it is appropriate to put the full description in this manpage, and the "boot" and "loader" manpages where this description might go are also missing a description of a number of similar variables, so i think this it is ok to limit documentation to this now, and update it later when I (or someone else) have a chance to revise "boot" and "loader".

* Export a (machine dependent) kernel variable bootdev asluigi2002-03-101-0/+51
| | | | | | | | | | | | | | | | | | | | | | machdep.guessed_bootdev, and add code to sysctl to parse its value and give a (not necessarily correct) name to the device we booted from (the main motivation for this code is to use the info in the PicoBSD boot scripts, and the impact on the kernel is minimal). NOTE: the information available in bootdev is not always reliable, so you should not trust it too much. The parsing code is the same as in boot2.c, and cannot cover all cases -- as it is, it seems to work fine with floppies and IDE disks recognised by the BIOS. It _should_ work as well with SCSI disks recognised by the BIOS. Booting from a CDROM in floppy emulation will return /dev/fd0 (because this is what the BIOS tells us). Booting off the network (e.g. with etherboot) leaves bootdev unset so the value will be printed as "invalid (0xffffffff)". Finally, this feature might go away at some point, hopefully when we have a more reliable way to get the same information. MFC-after: 5 days

Possible extensions to sysctl: + report variables that do not have a description + given a name, report the oid it maps to. Note to developers: have a look at your code, there are a number of variables which do not have a description. Note to developers: do we want this in 4.5 ? It is a very small change and very useful for documentation purposes. Suggested by: Orion Hodson
