50bdd70043 Allow cluster mirrors to handle the absence of the checkpoint lib (libSaCkpt).
The OpenAIS checkpoint library is going away; therefore, cmirrord must
operate without it.  The algorithms the handle the timing of when to send
a checkpoint, the determination of what to send, and which ongoing cluster
requests are relevent with respect to the checkpoints are unaffected.  We
need only replace the functions that actually perform the storing/transmitting
and retrieving/receiving of the checkpoint data.  Rather than store the
checkpoint data in an OpenAIS checkpoint file, we simply transmit it along
with the message that notifies the incoming node that the checkpoint is
ready.

73c46fa222 Add configure --with-tmpfilesdir and lvm2 tmpfiles.d configuration file itself.
/etc/tmpfiles.d directory holds configuration files for temporary/volatile
files and directories that should be automatically managed. For example,
if we have some parts of the fs hierarchy on tmpfs, we'd like to recreate
some files or directories on every boot so they're always prepared for use.

Systemd can read such configuration files. For now, the lock and run directory
are the ones that are most probably placed on tmpfs. If this is the case, we
can install the configuration by 'make install_tmpfiles_configuration'.

bd746876ee Check whether udev supports built-in blkid.
Built-in blkid is supported since udev v176 - set the UDEV_HAS_BUILTIN_BLKID
variable appropriately so we can use it in the rules to call the built-in
blkid conditionaly.

cd4fce855e Add configure --with-default-name-mangling.
This option configures the default name mangling mode used, one of:
AUTO, NONE and HEX.

The name mangling is primarily used to support udev character whitelist
(0-9, A-Z, a-z, #*-.:=@_) so any character that is not on udev whitelist
will get translated into an encoded form \xNN where NN is the hex value
of the character.

e55220e27a Implement a CUnit-based runner for unit tests. Copy and adapt (actual unit)
tests from unit-tests/*/*_t.c (now under test/unit). The valgrind/pool test is
missing, since it's not really a unit test and probably not too valuable
either. Available via "make unit" (and if --enable-testing was passed to
configure, also executed by make check).

dd815a4f7b Make dmsetup.static and lvm.static build when dmeventd is disabled.
udev may also need to be disabled if you didn't build it statically too.

dmeventd.static could be fixed with some more work but I don't really see the
point: without dlopen() it's useless, and if you have dlopen(), why not support
normal shared libraries too?

c4d973530f A compromise integration of LVMetaD into the build: I have kept all the
daemon/common code in a single libdaemon.a, which is completely private. This
is currently linked into the lvmetad binary, and will be linked into LVM (the
client part, since static linking only picks up only symbols that are actually
used). I have also added --enable/disable-lvmetad to ./configure; although the
current default is off, I expect this to be flipped to on shortly. There's no
LVM-side support yet, but when there is, even when built, it'll still need to
be enabled by an lvm.conf option.

Basic support includes:
- ability to create RAID 1/4/5/6 arrays
- ability to delete RAID arrays
- ability to display RAID arrays
Notable missing features (not included in this patch):
- ability to clean-up/repair failures
- ability to convert RAID segment types
- ability to monitor RAID segment types

With udev system natural options should be  'resume'.

a1cbc61c34 Add new dm_prepare_selinux_context fn to libdevmapper and use it throughout.
Detect existence of new SELinux selabel interface during configure.
Use new dm_prepare_selinux_context instead of dm_set_selinux_context.

We should set the SELinux context before the actual file system object creation.
The new dm_prepare_selinux_context function sets this using the selabel_lookup
fn in conjuction with the setfscreatecon fn. If selinux/label.h interface
(that should be a part of the selinux library) is not found during configure,
we fallback to the original matchpathcon function instead.

d99a0313a7 Add OCF support
Updated patch from Florian Haas from Linux-HA project.

User needs to 'configure --enable-ocf' to get file installed
by 'make install' target by default.
User can also use 'make install_ocf' to get only ocf files installed.
With disabled (default) ocf support - no ocf files are installed.

FIXME: ocf installation path needs to be kept in sync with pacemaker.

919568a223 Don't use floor() in _bitset_with_random_bits
Use _even_rand() function instead of floor() in _bitset_with_random_bits().
floor() function is missing in dietlibc (on architectures other than x86).
Moreover using floor() to clip rand results does not assure even result
distribution. _even_rand() uses integer arithmetic only and is designed to
return evenly distributed results.
