900f5f8187 Replace dynamic buffer allocations for PATH_MAX
Use static buffer instead of stack allocated buffer.
This reduces stack size usage of lvm tool and the
change is very simple.

Since the whole library is not thread safe - it should not
add any new problems - and if there will be some conversion
it's easy to convert this to use some preallocated buffer.

07113beea3 Do not scan device if it is part of active multipath.
Add filter which tries to check if scanned device is part
of active multipath.

Firstly, only SCSI major number devices are handled in filter.

Then it checks if device has exactly one holder (in sysfs) and
if it is device-mapper device and DM-UUID is prefixed by "MPATH-".

If so, this device is filtered out.

The whole filter can be switched off by setting
mpath_component_detection in lvm.conf.

Properly detect if the filters were refreshed properly.

(May needs few more fixes ??)

Filter refresh may fail because it may be out of free file descriptors

125712bea0 Replace open_count check with holders/mounted_fs check on lvremove path.
Before, we used to display "Can't remove open logical volume" which was
generic. There 3 possibilities of how a device could be opened:
  - used by another device
  - having a filesystem on that device which is mounted
  - opened directly by an application

With the help of sysfs info, we can distinguish the first two situations.
The third one will be subject to "remove retry" logic - if it's opened
quickly (e.g. a parallel scan from within a udev rule run), this will
finish quickly and we can remove it once it has finished. If it's a
legitimate application that keeps the device opened, we'll do our best
to remove the device, but we will fail finally after a few retries.

handle `struct device` and `struct cmd_context`, basically). A number of

418663b61c Disable udev fallback by default and add activation/udev_fallback to lvm.conf.
We've used udev fallback code till now to check whether udev
created/removed the entries in /dev correctly and if not,
a repair was done (giving a warning messagea about that).

This patch adds a possibility to enable this additional check
and subsequent fallback only when required (debugging purposes
mostly) and trust udev completely.

So let's disable the fallback code by default and add a new
configuration option "activation/udev_fallback".

(The original code for creating the nodes will still be used
in case the device directory that is set in lvm.conf differs
from the one that udev uses and also when activation/udev_rules
is set to 0 - otherwise we would end up with no nodes/symlinks
at all)

eee66d2a80 When glibc needs buffers for line buffering of input and output buffers, it
allocates these buffers in such way it adds memory page for each such buffer
and size of unlock memory check will mismatch by 1 or 2 pages.

This happens when we print or read lines without '\n' so these buffers are
used. To avoid this extra allocation, use setvbuf to set these bufffers ahead.

edcda01a1e Obtain device list from udev by default if LVM2 is compiled with udev support.
Also, add a new 'obtain_device_list_from_udev' setting to lvm.conf with which
we can turn this feature on or off if needed.

If set, the cache of block device nodes with all associated symlinks
will be constructed out of the existing udev database content.
This avoids using and opening any inapplicable non-block devices or
subdirectories found in the device directory. This setting is applied
to udev-managed device directory only, other directories will be scanned
fully. LVM2 needs to be compiled with udev support for this setting to
take effect. N.B. Any device node or symlink not managed by udev in
udev directory will be ignored with this setting on.

9ad39e546b Currently if clvmd is running and user issues vgscan,
the device cache file is dumped both in vgscan and clvmd process.

Unfortunately, clvmd calls lvmcache_label_scan,
it properly destroys persistent filter, but during
persistent_filter_dump it merges old cache content back!

This causes that change in filters is not properly propagated
into device cache after vgscan on cluster.
(Only new devices are added.)

For mirror repair (and similar tasks) it can happen that full

Because code can be in the middle of repair (calling suspend)
clvmd should never try to scan suspended devices
(otherwise it causes deadlock).

e1ab01e3ad Refresh device filters before full device rescan in lvmcache.
The sysfs filter initialise hash of available devices using
scan of /sys/block. We need to refresh even this hash
when performing full scan otherwise the newly appeared
device could be rejected, because there is no entry
in sysfs filter.

This easily could happen when attaching new device
to cluster node. (Only force refresh of context
in clvmd -R works here now).

Unfortunately consequences of this are much worse,
missing device part on that node is replaced with missing segment
(even when no partial arg is selected) and this directly
lead to data corruption.

See https://bugzilla.redhat.com/show_bug.cgi?id=538515

Simply fix it by refreshing device filters in lvmcache
before performing the full device scan.

9a04baa27c Move initialization of cmd->fmt into init_formats().
init_formats() sets up the command formats, and currently sets cmd->fmt_backup
but does not set cmd->fmt to a default value.  This seems incorrect so we
set it to cmd->default_settings.fmt before returning.

The call we remove here may set cmd->fmt based on a command line setting.
But it is safe to remove this, because the only caller of init_lvm() that
cares about the cmdline override is the cmdline tools (clvmd does not care),
called from lvm2_main().  After lvm2_main() calls init_lvm(), it later calls
lvm_run_command().  In lvm_run_command(), we have a call to _apply_settings(),
which has the identical assignment of cmd->fmt that this patch removes.

4fa2c7f8b6 Remove archive_enable() calls after create_toolcontext() calls.
_init_backup() calls archive_init(), which originally set 'enabled' to
a hardcoded '1' value.  This seems incorrect based on my read of other
areas of the code so here we add a 'enabled' paramter to archive_init().
We pass in cmd->default_settings.archive, which is obtained from the
config tree.  Later in create_toolcontext, cmd->current_settings is
set to cmd->default_settings.  The archive_enable() call we remove
here was using cmd->current_settings to set the 'archive' enable
value.  The final value of cmd->archive_params->enabled should thus
be equivalent to the original code.

058f3d3523 Move init_test() from _apply_settings into _init_logging().
This one we actually need to move.  _init_logging() is called from
    create_toolcontext(), which makes this call:
        /* Test mode */
        cmd->default_settings.test =
            find_config_tree_int(cmd, "global/test", 0);

But it does not call init_test().  So we need an init_test() somewhere.
The most logical place is to put it inside _init_logging(), since this
is where the config value is read and default_settings are set.  Placing
the init_test() call here matches what is done with other variables and
seems to make sense.

25b733809a Merge with text format branch.
Lots of changes/very little testing so far => there'll be bugs!

Use 'vgcreate -M text' to create a volume group with its metadata stored
in text files.  Text format metadata changes should be reasonably atomic,
with a (basic) automatic recovery mechanism if the system crashes while a
change is in progress.

Add a metadata section to lvm.conf to specify multiple directories if
you want (recommended) to keep multiple copies of the metadata (eg on
different filesystems).

e.g. metadata {
        dirs = ["/etc/lvm/metadata1","/usr/local/lvm/metadata2"]
}

Plenty of refinements still in the pipeline.
