(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.
and libdevstat, since the new way of doing things is to just list
maintainership in src/MAINTAINERS.
Also, remove duplicate entries in src/MAINTAINERS for those utilities. I
already had entries for them.
number X, rather than mdX, making it easier to script tests that
use md devices but don't want to make assumptions about any existing
md use (such as in diskless environments).
Change the list interface to simplify things.
Remove old list ioctls which bogusly exported the softc to userland.
Move the softc and associated structures from the public header to
the source file.
hinge on the "verb" parameter which the class gets to interpret as
it sees fit.
Move the entire request into the kernel and move changed parameters
back when done.
with UFS1, the UFS1 superblocks were not deleted. This allowed any
RELENG_4 (or other non-UFS2-aware) fsck to think it knew how to "fix"
the file system, resulting in severe data scrambling.
This patch is a more advanced version than the one originally submitted.
Lukas improved it based on feedback from Kirk, and testing by me. It
blanks all UFS1 superblocks (if any) during a UFS2 newfs, thereby causing
fsck's that are not UFS2 aware to generate the "SEARCH FOR ALTERNATE
SUPER-BLOCK FAILED" message, and exit without damaging the fs.

one or more actions in the list. This makes constructs like:
attach 10 {
// echo "Driver $device_name attached"
};
to be accepted by the parser. It will be treated as if the user had
entered:
// attach 10 {
// echo "Driver $device_name attached"
// };
(eg totally ignored).
