661b2c1683 Fix what I think is an off-by-one in certain worst-case scenarios
caused by rev 1.45.  (eg: the estimate being exactly half of the result.)

9866352ec7 Fix a "bug" in sysctl(8). Limit the length when we print a string from
the kernel rather than ignoring the length and keeping on going till we
finally hit a \0 character in the buffer.

b35c8f287d Take the "tickadj" element out of struct clockinfo. Our adjtime(2)
implementation is being changed and the very concept of tickadj will
no longer be meaningful.

bca9bbeae7 Make the handling of machdep.guessed_bootdev compiled on i386 only. 2002-03-11 06:50:28 +00:00

60cf2c1254 Export a (machine dependent) kernel variable bootdev as
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.

ce68584226 #include <sys/time.h> instead of depending on namespace pollution in

d58f005463 Allow setting of variables of type dev_t by indicating the name of
a special file on the command line, eg:
  sysctl kern.dumpdev=/dev/ad1s1b

In parse(), when a value is given for a CTLTYPE_QUAD variable,
newval and newsize erroneously fail to be set because of an early
"break".

show_var() contains code that duplicates the functionality of the
oidfmt() function.

6105f81565 Add code to export and print the description associated to sysctl
variables. Use the -d flag in sysctl(8) to see this information.

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.

d0b8aabb19 Implement -e option. It modifies the output produced by sysctl(8) in
such a way that the name and the value of the variable(s) are separated
with `=' instead of the usual `: '.  This is useful for producing output
that can be fed back to the sysctl utility (pasted to sysctl.conf, for
example).

9a2402bc41 Try to make sysctl options slightly more orthogonal:
- introduce a -o option that displays opaque variables.
 - introduce a -x option that displays opaque variables in full.
 - deprecate -A in favor of -ao and -X in favor of -ax.
 - remove -A and -X from usage() and SYNOPSIS (but not from DESCRIPTION).
 - ignore -a if one or more variables were listed on the command line.
 - deprecate -w, it is not needed to determine the user's intentions.
 - some language and style cleanup in the man page.

This commit should not break any existing scripts.
