- The ability to specify elements by volume tag instead of their actual
physical location. e.g., instead of:
chio move slot 3 slot 4
you would now use:
chio move voltag FOO slot 4
- The ability to return an element to its previous location, as specified
by the source element. e.g., instead of:
chio move drive 0 slot 4
you would now use:
chio return drive 0
or
chio return voltag FOO
These features will obviously only work with changers that support volume
tags and/or source element IDs. chio(1) should fail gracefully if the user
attempts to use these new features and the source element ID or volume tag
are not found.

Problem in this code originally spotted by
Jun Kuriyama <kuriyama@FreeBSD.org>
growstackblock() sometimes relocates a stack_block considered empty
without properly relocating stack marks referencing that block.
The first call to popstackmark() with the unrelocated stack mark
as argument then causes sh to abort.
Relocating the relevant stack marks seems to solve this problem.
The patch changes the semantics of popstackmark() somewhat. It can
only be called once after a call to setstackmark(), thus cmdloop() in
main.c needs an extra call to setstackmark().

interface, and statically link them to the programs using them.
These functions, upon reflection and discussion, are too generically
named for a library interface with such specific functionality.
Also the api that they use, whilst ok for private use, isn't good
enough for a libc function.
Additionally there were complications with the build/install-world
process. It depends heavily upon xinstall, which got broken by
the change in api, and caused bootstrap problems and general mayhem.
There is work in progress to address future problems that may be
caused by changes in install-chain tools, and better names for
{g|s}etflags can be derived when some future program requires them.
For now the code has been left in src/lib/libc/gen (it started off
in src/bin/ls).

more and more other tools have used these private functions to

Recently I moved these functions from /usr/src/bin/ls to libutil,
but after some discussion with bde it's been decided that they
really ought to go in libc.
There are two already existing libc functions for manipulating file
modes: setmode and getmode. In keeping with these flags_to_string
has been renamed getflags and string_to_flags to setflags.

Turn off setgid-kmem for /bin/ps, it's now quite functional without it.
ps no longer needs /dev/*mem or /proc. (It will still use some /proc
files if they are available for -e, but it's not required, so it'll
happily run in a jail or chroot).
The proc stats are now part of eproc (obtained via sysctl) and no longer
needs to beat up the u-page reading code and the problems with that.
This also has the side effect of disabling 'ps -e' for normal users
*EXCEPT* when looking at their own processes. ie: they can see
environments in processes with their uid, enforced by the ownership of
/proc/*/mem. Root can still see them all, as it can open all /proc/*/mem.
This fixes some nasty procfs problems for SMP, makes ps(1) run much faster,
and makes ps(1) even less dependent on /proc which will aid chroot and
jails alike.

avoid stat()-ing entries that do not represent "real" disk mount

also useful not to have to stat() these entries because it takes
longer to report them that for other file systems, being that these
mount points are served by a user-level file server and resulting in
several context switches. Worse, if the automounter is down

Support for negative offsets is gone again, but the case where you

The biggest changes are to data types (more size_t, for instance) and
argument parsing. skip/seek on /dev/{,k}mem now occurs (instead of "read
until you reach the offset") due to mem devices now being D_DISK. Some
const things are now correctly declared as such, and the "case table"
building is better. The only thing that seems to be left to make dd(1)
