9 years agopvcreate: switch to "none" dev-ext source during pvcreate

pvcreate: switch to "none" dev-ext source during pvcreate

pvcreate code path executes signature wiping if there are any signatures
found on device to prepare the device for PV. When the signature is wiped,
the WATCH udev rule triggers the event which then updates udev database
with fresh info, clearing the old record about previous signature.

However, when we're using udev db as dev-ext source, we'd need to wait
for this WATCH-triggered event. But we can't synchronize against such
events (at least not at this moment). Without this sync, if the code
continues, the device could still be marked as containing the old
signature if reading udev db. This may end up even with the device
to be still filtered, though the signature is already wiped.

This problem is then exposed as (an example with md components):

$  mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sda /dev/sdb --run
$  mdadm -S /dev/md0
$  pvcreate -y /dev/sda
Wiping linux_raid_member signature on /dev/sda.
/dev/sda: Couldn't find device.  Check your filters?
$ echo $?
5

So we need to temporarily switch off "udev" dev-ext source here
in this part of pvcreate code until we find a way how to sync
with WATCH events.

(This problem does not occur with signature wiping which we do
on newly created LVs since we already handle this properly with
our udev flags - the LV_NOSCAN/LV_TEMPORARY flag. But we can't use
this technique for non-dm devices to keep WATCH rule under control.)

tolllib: process_each_pv: always use full_filter unconditionally when getting all devices

(This reverts patch #d95c6154)

Filter complete device list through full_filter unconditionally when
we're getting the list of *all* devices even in case we're interested
only in fraction of those devices - the PVs, not the other devices
which are not PVs yet (e.g. pvs vs. pvs -a).

We need to do this full filtering whenever we're handling *complete*
list of devices, we need to be safe here, mainly if there are any
future changes and we'd forgot to change to use proper filtering then.
Also properly preventing duplicates if there are any block subsystem
components used (mpath, MD ...).

Thing here is that (under use_lvmetad=1), cmd->filter can be used
only if we're sure that the list of devices we're filtering contains
only PVs. We have to use cmd->full_filter otherwise (like it is in
case of _get_all_devices fn which acquires complete list of devices,
no matter if it is a PV or not).

Of course, cmd->full_filter is more extensive than cmd->filter
which is only a subset of full_filter.

We could optimize this in a way that if we're interested in PVs only
during process_each_pv processing (e.g. using pvs in contrast to pvs -a),
we'd get the list of PV devices directly from lvmetad from the
lvmcache_seed_infos_from_lvmetad fn call which currently updates
lvmcache only. We'd add an additional output arg for this fn to get
the list of PV devices directly in addition, without a need to iterate
over all devices which include non-PVs which we're not interested in
anyway, hence we could use only cmd->filter, not the cmd->full_filter.

So the code would look something like this:

static int _get_all_devices(....)
{
struct device_id_list *dil;

if (interested_in_pvs_only)
lvmcache_seed_infos_from_lvmetad(cmd, &dil); /* new "dil" arg */
/* the "dil" list would be filtered through cmd->filter inside lvmcache_seed_infos_from_lvmetad */
else {
lvmcache_seed_infos_from_lvmetad(cmd, NULL);
dev_iter_create(cmd->full_filter)
while (dev = dev_iter_get ...) {
dm_list_add(all_devices, &dil->list);
}
}
}

This is a followup patch for previous patchset that enables selection in
process_each_* fns to fix an issue where field prefixes are not
automatically used for fields in selection criteria.

Use initial report type that matches the intention of each process_each_* functions:
- _process_pvs_in_vg - PVS
- process_each_vg - VGS
- process_each_lv and process_each_lv_in_vg - LVS

This is not normally needed for the selection handle init, BUT we would
miss the field prefix matching, e.g.

lvchange -ay -S 'name=lvol0'

The "name" above would not work if we didn't initialize reporting with
the LVS type at its start. If we pass proper init type, reporting code
can deduce the prefix automatically ("lv_name" in this case).

This report type is then changed further based on what selection criteria we
have. When doing pure selection, not report output, the final report type
is purely based on combination of this initial report type and report types
of the fields used in selection criteria.

toollib: replace void *handle with struct processing_handle for use in processing functions (process_each_*/process_single_* and related)

This patch replaces "void *handle" with "struct processing_handle *handle"
in process_each_*, process_single_* and related functions.

The struct processing_handle consists of two handles inside now:

  - the "struct selection_handle *selection_handle" used for
    applying selection criteria while processing process_each_*,
    process_single_* and related functions (patches using this
    logic will follow)

  - the "void* custom_handle" (this is actually the original handle
    used before this patch - a pointer to custom data passed into
    process_each_*, process_single_* and related functions).

libdm: report: add dm_report_object_is_selected

The new dm_report_object_is_selected fn makes it possible to opt whether the
object reported should be displayed on output or not. Also, in addition to
that, it makes it possible to save the result of selection (either 0 or 1).

So dm_report_object_is_selected is simply  more general form of object
reporting fn - combinations now allow for:

  dm_report_object_is_selected(rh, object, 1, NULL):
  This is exactly the original dm_report_object fn and it's fully equal
  to it.

  dm_report_object_is_selected(rh, object, 0, selected):
  Do not display the result on output, but save info whether the object
  is selected or not in 'selected' variable.

  dm_report_object_is_selected(rh, object, 1, selected):
  Display the result on output (if it passes selection criteria) and save
  whether the object is selected or not in 'selected' variable.

  dm_report_object(rh, object, 0, NULL):
  This combination is not allowed - it will end up with internal error.
  We're either interested in selection status or we want to display the
  result on output or both, but never nothing of the two.
