this breaks abstraction. Because only lvmtools/lvmlib and device-mapper can
have knowledge about target mapping and libdevmapper only passes requests
from lvmtools to kernel and back. Bump major library and driver version.

allocated with length DM_MAX_PARAMS_SIZE and released with strlen + 1 size.
Disable KM_NOSLEEP allocation because we do not need them here there is
nothing critical in ioctl part of dm driver.
Bug reported by jak@.
- Limit accesses to the size of the volume.
This fixes a KASSERT in physio_biodone().
- Change dm_table_size() to return the size of the volume in
DEV_BSIZE units. It was reporting it in DEV_BSIZE^2 units.
- Remove a bit of trailing whitespace.

partutil.c::getdiskinfo to use it to get disk geometry info.
Use DIOCGWEDGEINFO ioctl to get information about partition size, if disk
driver doesn't support it use old DIOCGDINFO. This patch adds support for
wedge like devices(lvm logical volumes, ZFS zvol partitions) to newfs and
other tools.
No objections on tech-userlevel@.
Create proplib param dictionary entry in libdevmapper and pass it to dm in
dm_ioctl dict.
Param target is then passed to target init function, where is parse. I like
this aproach much better than passing char **argv and trusting to user input.
I have bumped minor lib/driver version.
XXX. Add more sanity checks in kernel.
to 2 for now. strategy routine must be written, for now only parsing and
support routines are available. This is work in progress code and should be
taken very carefully.
that we have to run lvm vgchange -a n before modunload in NetBSD.
We really need to disable module unloading only for mounted devices, I have
to look at vfs_hooks for mount/umount calls and find way how to mark devices
as mounted in dm driver.
linear can be loaded as module. Module is not loaded when there is target
with similar name already. Zero and error targets aresimple examples how
can be all future targets written to support dynamic loading. Target can't
be unloaded until there is at least one user.
the base NetBSD system. It uses Linux LVM2 tools and our BSD licensed
device-mapper driver.
The device-mapper driver can be used to create virtual block devices which
maps virtual blocks to real with target mapping called target. Currently
these targets are available a linear, zero, error and a snapshot (this is
work in progress and doesn't work yet).
The lvm2tools adds lvm and dmsetup binary to based system, where the lvm
tool is used to manage and administer whole LVM and the dmestup is used to
communicate iwith device-mapper kernel driver. With these tools also
a libdevmapper library is instaled to the base system.
Building of tools and driver is currently disable and can be enabled with
MKLVM=yes in mk.conf. I will add sets lists and rc.d script soon.
