4fe498363c Add VINUM_SETSTATE_FORCE ioctl for diddling individual object states.
This is a repair tool which can also be used for panicing the system.
Use with utmost care if at all.

55eecd1064 vinumioctl: add ioctls for raw subdisks and plexes. Remove code for
drives (we refuse to touch drives, that's the disk driver's business).

8cb67ba580 Revise use of the vinum_conf variables drives_used, subdisks_used,
plexes_used and volumes_used.  Now these fields are only informative,
and the <object>_allocated count is used for searches, etc.  This also
required checking the object state before doing things with the
presumed object.

VINUM_<object>CONFIG: return ENXIO rather than EFAULT if an object
doesn't exist.

301851b630 VINUM_RESETCONFIG: do the reset even if the config is open (as it has
to be for us to issue the ioctl :-).  Also remove the opencount
parameter of the config, which just never worked.

33e00380bc Change printf() calls to log() calls.
Change VINUM_SAVECONFIG: it now requires a parameter.  0 means
"configuration updates are finished, please save", and 1 means "please
just save the config".  This second meaning is invoked by the new
"saveconfig" command to vinum(8).

c3dff4f036 Include Peter Wemm's renaming and restructuring
Remove #ifdefs for FreeBSD 2.c

Change from lkm to kld

correct type of `flags' in calls to set_drive_state.

set_drive_parms: handle anonymous drives correctly (remove them)

drive VOP functions: use the PID of the original opener to fool the
lock manager.

open_drive: be quiet about failures (they're normal when scanning the
partitions).

close_drive: lock drive before closing.

remove_drive: lock drive before deallocating.

read_drive_label: set drive up when all is OK

check_drive:
  Complete rewrite.  Offload most of the code to the new
  vinum_scandisk

format_config:
  use snprintf and %qd options to make much less emetic.
  Remove old supporting functions.

vinum_scandisk:
  Moved here from vinum.c
  Almost complete rewrite, incorporating much of what was check_drive.
  We still don't have a general way to find the drives on a system, so
  get the user to supply the names via the `read' command.  For each
  device, try each possible compatibility slice name (there's a danger
  of finding both /dev/da1h and /dev/da0s1h otherwise).  Sort the
  partitions found in reverse order of last update time and read them
  in, setting the `update' parameter to parse_config and descendents.

save_config: rename to daemon_save_config, since the function is now
called by the daemon.  Create a new function save_config which queues
the request with the daemon.

daemon_save_config:  some mods to allow for the unfamiliar
environment.

c285ca1254 Some relatively minor tweaks to enable vinum to be built into a static
kernel as a pseudo-device.  The changes were:
- #ifdef DEBUG -> #ifdef VINUMDEBUG
- opt_vinum.h for holding above config variable
- Fixing up a few stray problems where DEBUG wasn't optional.
- config.c -> vinumconfig.c (there's already a config.o)
- Other *.c -> vinum*.c (wasn't strictly necessary, but done in case we end
  up with something else conflicting later on and we might have to have yet
  more repository copies of files).
- include file paths fixups..  (ie: get them all from the kernel tree
  instead of partly from the kernel and partly from /usr/include/machine)

I've spoken with Greg about this..  I hope this doesn't mess him around
too much..

ef2dbe9885 If I've done this right, revive the vinum code in it's now home after it
was savaged in the blood bath a few hours ago.

721fbc5ae0 config.c:
config_drive:
    Catch an instance of anonymous drives.  Doubtless many remain.

interrupt.c:
  complete_rqe:
    Call logrq to log iodone events if DEBUG_LASTREQS is set.

    Call set_sd_state with setstate_noupdate to avoid buffered I/O out
    of interrupt context.

    Use define DEBUG_RESID instead of constant.

memory.c:
  Remove dead expandrq() function

  Malloc:
    Remove directory component of file names in malloc table.

  Add function vinum_rqinfo (part of the request tracing stuff).

request.c:
  Add function logrq (part of the request tracing stuff).

  vinumstrategy:
    Check whether config needs to be written to disk, do it if so.
    This is a stopgap until the Vinum daemon (bacchusd?  oenologistd?)
    is written.

    If DEBUG_LASTREQS is set, call logrq to log user buffer headers.

  launch_requests:
    Correct format of debug output to console.

    If DEBUG_LASTREQS is set, call logrq to log request elements.

request.h:
  Add definitions for request trace.

state.c:
  set_sd_state:
    Check flags for setstate_noupdate.  If set, don't write the config
    to disk, just set global VF_DIRTYCONFIG flag.  This is part of the
    kludge to avoid writing config from an interrupt context.

vinumext.h:
    Add declaration for vinum_rqinfo, put inside #ifdef DEBUG
    Remove dead macro expandrq

vinumio.h:
  Increase maximum ioctl reply length to 4 kB if DEBUG is set.
  Define VINUM_RQINFO ioctl if DEBUG is set.

vinumioctl.c:
  vinumioctl:
    Change implementation of VINUM_DEBUG ioctl: use a debug flag
    (DEBUG_REMOTEGDB) to decide whether to go into remote debugging or
    not.

    Implement VINUM_RQINFO.

vinumkw.h:
  Define kw_info even when not debugging.

vinumvar.h:
  Define VF_DIRTYCONFIG
  Add pointers to request info to vinum_info if DEBUG is set.
  Define setstate_noupdate
  Define additional debug bits DEBUG_RESID, DEBUG_LASTREQS and
  DEBUG_REMOTEGDB.
