c737d34804 Use vpath instead of VPATH.
Usage of VPATH makes troubles when used within $(builddir).
Not only source files are being found through VPATH,
but targets as well. (make --debug=v)

Thus if user builds the code in $(srcdir) and also in some $(builddir)
he gets mangled results as some generated files (i.e. .export.sym)
are 'reused' from $(srcdir) instead of $(builddir).

This patch switches to use vpath were we could explicitly name
suffixes that should be looked via vpath - we must take care,
we do not generate files with these suffixes:
.c, .in, .po, .exported_symbols

b41f5924bf Update cflow file generation - support build dir and use $(top_srcdir)
to obtain sources. Create make.tmpl target for
simplier generation of cflow files with the help of
CFLOW_LIST, CFLOW_LIST_TARGET, CFLOW_TARGET.
Still cflow usage is not perfect.

91345610f8 Strictly require libudev if udev_sync is used.
This prevents some confusion when libudev was not found so udev_sync was disabled
automatically. Configure was successful though giving only a tiny warning.

Also, if "dmsetup udevcreatecookie" is used, never return 0x000000 as a result if
udev is not running and keep the output blank.

ac3691f70e Add support for ioctl's DM_UEVENT_GENERATED_FLAG.
We need to know whether we should wait for any uevent or not when
using udev_sync. A kernel patch was posted recently that changed the
way uevents are sent on dm device resume - it is sent only if the
device has been suspended before. There's also a new DM_UEVENT_GENERATED_FLAG
in the ioctl to notify userspace whether the event was generated.

If the uevent was not generated (e.g. the situation where the device is
*not* suspended and we call a resume), we just call dm_udev_complete
explicitly from within libdevmapper itself to prevent infinite waiting
while trying to synchronise with udev processing.

f8f6ec92b1 This patch add SELINUX_LIBS and STATIC_LIBS variables.
For static builds dependency for SELinux libs is not handled by 'ar'.
Till better solution is found, for static builds STATIC_LIBS is used.

Patch updates SELinux detection to use 3rd & 4th parameter for Success/Fail.
Also removes detection of pthread from this check as we know which
version of libdevmapper we are going to link with lvm after merge.

SELinux header check moved to the SELinux test code.

f0e073fcdc Several changes in dmsetup and libdevmapper:
- add DM_UDEV_DISABLE_LIBRARY_FALLBACK udev flag to rely on udev only

 - export dm_udev_create_cookie function to create new cookies on demand

 - add --udevcookie, udevcreatecookie and udevreleasecookie for dmsetup
   (to support "udev transactions" where one cookie value can be used for
    several dmsetup calls)

 - don't use DM_UDEV_DISABLE_CHECKING env. var. anymore and set the state
   automatically (based on udev and libdevmapper dev path comparison)

49b95a5e21 Off-by-one count was causing not all the mirror table parameters
that were necessary to be passed on to userspace.

The cluster mirror table (log portion only) used to look like this:
        clustered-disk <parm_count> <disk> <region_size> <uuid> \
                        [[no]sync] [block_on_error]
Now it looks like this:
        userspace <parm_count> <uuid> clustered-disk <disk> <region_size> \
                        [[no]sync]

So, there is one extra argument in the latter case - this was
unaccounted for.

aa6f4e51a7 Add support for "snapshot-merge" target.
Introduces new libdevmapper function dm_tree_node_add_snapshot_merge_target

Verifies that the kernel (dm-snapshot) provides the 'snapshot-merge'
target.

Activate origin LV as snapshot-merge target.  Using snapshot-origin
target would be pointless because the origin contains volatile data
while a merge is in progress.

Because snapshot-merge target is activated in place of the
snapshot-origin target it must be resumed after all other snapshots
(just like snapshot-origin does) --- otherwise small window for data
corruption would exist.

Ideally the merging snapshot would not be activated at all but if it is
to be activated (because snapshot was already active) it _must_ be done
after the snapshot-merge.  This insures that DM's snapshot-merge target
will perform exception handover in the proper order (new->resume before
old->resume).  DM's snapshot-merge does support handover if the reverse
sequence is used (old->resume before new->resume) but DM will fail to
resume the old snapshot; leaving it suspended.

To insure the proper activation sequence dm_tree_activate_children() was
updated to accommodate an additional 'activation_priority' level.  All
regular snapshots are 0, snapshot-merge is 1, and merging snapshot is 2.

d2b43c4b34 Add support to disable udev checking: DM_UDEV_DISABLE_CHECKING=1 env. variable.
Sometimes it is really needed to switch off udev checking and the warnings we show when
we detect that udev has not done its job right - the messages like "Udev should have done
this and that. Falling back to direct node creation/removal. " etc.

This would be especially handy while setting DM_DEV_DIR env var that could be set to a
different location than standard /dev (udev can't create nodes/symlinks out of that one
directory that is configured into udevd). The exact same situation happens while we're
running our tests.

ccb601a3cb Remove unnecessary / duplicate dm_list macros and functions.
These are no longer used by anyone.  The dm_list defines are all in
libdevmapper.h and libdm/datastruct/list.c contains any function definitions.
There is some code in "old-tests" that still use this but this code is not
being maintained.

584d1fb7d1 Support udev flags even when udev_sync is disabled or not compiled in.
This provides better support for environments where udev rules are installed
but udev_sync is not compiled in (however, using udev_sync is highly
recommended). It also provides consistent and expected functionality even
when '--noudevsync' option is used.

There is still requirement for kernel >= 2.6.31 for the flags to work though
(it uses DM cookies to pass the flags into the kernel and set them in udev
event environment that we can read in udev rules).

From now on, we require foreign rules to check and honor

rules should be skipped totally when this flag is set.

421671b1c2 Several changes to udev support code:
- we have these levels when the udev rules are processed:
   10-dm.rules --> [11-dm-<subsystem>.rules] --> [12-dm-permissions.rules] -->
   13-dm-disk.rules --> [...all the other foreign rules...] --> 95-dm-notify.rules

 - each level can be disabled now by
   DM_UDEV_DISABLE_{DM, SUBSYSTEM, DISK, OTHER}_RULES_FLAG

 - add DM_UDEV_DISABLE_DM_RULES_FLAG to disable 10-dm.rules

 - add DM_UDEV_DISABLE_OTHER_RULES_FLAG to disable all the other (non-dm) rules.
   We cutoff these rules by using the 'last_rule', so this one should really be
   used with great care and in well-founded situations. We use this for lvm's
   hidden and layer devices now.

 - add a parameter for add_dev_node, rm_dev_node and rename_dev_node so it's
   possible to switch on/off udev checks

 - use DM_UDEV_DISABLE_DM_RULES_FLAG and DM_UDEV_DISABLE_SUBSYSTEM_RULES_FLAG
   if there's no cookie set and we have resume, remove and rename ioctl.
   This could happen when someone uses the libdevmapper that is compiled with
   udev_sync but the software does not make use of it. This way we can switch
   off the rules and fallback to libdevmapper node creation so there's no
   udev/libdevmapper race.

12ca060e9f Support crypt segment in libdevmapper tree.
- it can support multiple segments, but note that
to work properly, correct IV (initialization vector)
offset parameter must be set properly.

Because most usage of IV start offset is when we join
several crypto segments together (so iv_offset is the segment
start offset), DM_CRYPT_IV_DEFAULT is defined to simplify
the process.

Function accepts the string in cipher agrument (already
including chainmode and iv type; chainmode and iv parameters are NULL
in this case) or user can provide split parameters which will
join into dm-crypt cipher specification "cipher-chainmode-iv".

All these parameters must be supplied in correct dm-crypt format.

d917c98cd8 Fix some clean rules, fix previous distclean checkin.
In libdm/Makefile.in, we need to cleanup the symlink properly.
Adding to CLEAN_TARGETS seemed like the simplest way to do this
in the current build framework.  We could redo dependencies for
VERSIONED_SHLIB, but for now just add to CLEAN_TARGETS.

For scripts/Makefile.in, we should be adding to DISTCLEAN_TARGETS.
The generic rule in make.tmpl.in takes care of the cleanup.

ea0cdd28c1 Separate PV label attributes which do not need parse metadata when reporting.
When reporting explicitly label attributes (pv_uuid for example), we do not
need to read metadata.

This patch separate the label fileds and removes scan_vgs_for_pvs
in process_each_pv() if not needed.

(There should be no user visible change in output.)

1a0280b313 Rename _parse_options() to _parse_fields() for naming consistency.
In libdm, we only ever use 'fields', while the tools use 'options' and
'fields' interchangeably.

Ideally it would be good to use 'fields' consistently everywhere.
However, 'options' most likely comes from the tool commandline '-o' and
'--options' which cannot be changed.

1f1aaf43ea Add an "all" field which expands to all fields of the report type.
For example in LVM2, "pv_all" gives all PV fields.
"seg_all" gives all LV segment fields.

"all" gives all fields of the final report type.  I think this is more
useful than just adding the current prefix.

So "lvs -o seg_all" gives all the LV segment fields, whilst
"lvs --segments -o all" adds in LV and VG fields too.

"lvs -o all -O vg_name" has report type LVS+VGS so includes all LV and all
VG fields.

c48e40391b Add checks for device names in dmsetup and show proper error messages.
Checks added for DM device names to allow only names < DM_NAME_LEN,
otherwise a part of lengthy name would be silently ignored and could
cause confusion while using dmsetup. Also, the name should not contain
'/' character, if it is used in context of creating a new device
or renaming the existing one (because we do not consider full path
to devices, they do not exist in filesystem yet) and appropriate error
messages are shown.
