-
- The Darwin sysctl mechanism is in a state of flux. Parts of the kernel use the old
- style of BSD sysctl definition, and other parts use the new style. The sysctl (8)
- command that shipped with Darwin 1.2 (OS X PB) did not allow you to access
- all possible sysctl values. In particular, it did not permit access to sysctl values
- created by kernel extensions--hence my particular interest. The freeBSD sysctl (8)
- command compiled and ran under Darwin 1.2, and it did permit access to
- sysctl values created by kernel extensions, as well as several others. However, it
- did not permit access to many other values which the Darwin 1.2 sysctl could access.
-
- What I have done is merge the Darwin 1.2 sysctl and the freeBSD sysctl. Essentially,
- there are two points of merger. When showing all values (i.e. -a, -A, or -X), sysctl now
- runs the Darwin 1.2 routine to show all values, and then the freeBSD routine. This does
- result in some duplication. When getting or setting a particular value, sysctl now tries
- the freeBSD way first. If it cannot find the value, then it tries the Darwin 1.2 way.
-
- There are a few oddities which this creates (aside from some duplication with -a, -A,
- and -X). The freeBSD version of sysctl now supports two extra options, -b and -X.
- In this syctl, those options are supported where the value is retrieved by the freeBSD
- routine, and have no effect where the value is retrieved by the Darwin 1.2 routine.
- The freeBSD sysctl uses a ':' to separate the name and the value, whereas Darwin 1.2's
- sysctl uses a '='. I have left this way, as it lets you know which routine was used,
- should it matter.
-
- I have also fixed several lines which gave warnings previously, one of which appears
- to have been an actual bug (bufp was dereferenced when it shouldn't have been).
- I have also incoporated my previous patch to permit setting kern.hostid as an unsigned
- integer. In the freeBSD side of the code, I have incorporated a general fix for
- setting values where the format is specified as unsigned integer.
