36089b2236 Const warning fixes
With recent update of dm_report_field_string() API call to accept
completely const objects - we no longer need loose constness here
and keep it forwarding.

d0df875d48 Add configure option --with-device-nodes-on
Make configurable default behaviour how to deal with device node creates.
With udev system natural options should be  'resume'.
For older systems where user expect there is node in /dev/mapper immediately
after  dmsetup create --notable  -  use 'create'

FIXME:
Code needs fixing passing this flag through udev cookie.

880507498a Add --addnodeonresume, --addnodeoncreate
Add new function dm_task_set_add_node() to select between 2 types
of node creation in device directory.

DM_ADD_NODE_ON_RESUME is now default and ensures node is created on
resume. Old original behavior is accessible with DM_ADD_NODE_ON_CREATE.
In this case node would be created during dmsetup create --notable.

For the user 2 new options for dmsetup create are added:
[{--addnodeonresume | --addnodeoncreate }]

Properly working node creation on resume is needed for proper operation
stacking and ability to correctly check in which state the device should
after whole udev transation.

973db2a823 Test uuid for NULL
Add test for NULL before passing uuid as src argument to memcpy.
As memcpy function is declared as function not accepting NULL.
Though we pass NULL only with zero length so this patch presents
no functional change to the code.

942d6ef29f Add support for new IMPORT{db} udev rule.
This rule appeared in udev v152 and it helps us to support spurious events
where we didn't have any flags set (events originated in udevadm trigger
or the watch rule). These flags are important to direct the rule application.
Now, with the help of this rule, we can regenerate old udev db content.
To implement this correctly, we need to flag all proper DM udev events with
DM_UDEV_PRIMARY_SOURCE_FLAG. That happens automatically for all ioctls
generating events originated in libdevmapper.

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.

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)

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.

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).

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.

3395d72881 Change exit() to _exit() in the child process. exit flushes stdio file buffers,
_exit doesn't. If there were some open files, an error in exec and subsequent
exit() would cause the buffers to be flushed twice.

Example:

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/wait.h>

int main()
{
	printf("buu");
	if (!fork()) {
		execl("/bin/true-not-exists", "/bin/true", NULL);
		exit(1);
	}
	wait(NULL);
	return 0;
}

d43773d634 Wow, learn something new every day. Apparently, the signed-ness of char is

an unsigned char.

Alasdair Kergon
00ee56e232 Use additional version numbers.
Kernel driver has a version number (stored in kernel/VERSION).
  The first two components of this (0.94) give the version number of the
  ioctl interface.  This number must be changed whenever a change is
  made to the ioctl interface that breaks backwards compatibility.

  The library has a version number (stored in VERSION) which is
  used for linking.
  The first and/or second component of this must be changed whenever
  a change is made to the library API that breaks backwards
  compatibility.
