2567d03e95 cleanup: explicit prohibition for virtual segs
Internal _alloc_init() is only called from allocate_extents(),
which already does prevent usage of virtual segments.

So mark as internal error early and do not process it any further.

7f74a99502 lv: use brackets for invisible devices when formatting device segments
Include brackets for the name if the dev is invisible.
This change applies to all callers of _format_pvsegs fn:
  - lvseg_devices (the "lvs -o devices")
  - lvseg_metadata_devices (the "lvs -o metadata_devices)
  - lvseg_seg_pe_ranges (the "lvs -o seg_pe_ranges")
  - lvseg_seg_metadata_le_ranges (the "lvs -o seg_metadata_le_ranges")

d6cf83968c report: use brackets to signify LVs which are not visible when reporting lv_parent
Use common _lvname_disp to report lv_parent. The _lvname_disp
takes care of properly marking LVs which are not visible - such
LVs are always enclosed in brackets when reported within any
other field.

For example, thin pool over RAID.

Before:

$ lvs -a -o name,lv_parent,data_lv,metadata_lv vg
  LV                          Parent           Data               Meta
  cache_pool                                   [cache_pool_tdata] [cache_pool_tmeta]
  [cache_pool_tdata]          cache_pool
  [cache_pool_tdata_rimage_0] cache_pool_tdata
  [cache_pool_tdata_rimage_1] cache_pool_tdata
  [cache_pool_tdata_rmeta_0]  cache_pool_tdata
  [cache_pool_tdata_rmeta_1]  cache_pool_tdata
  [cache_pool_tmeta]          cache_pool

  [cache_pool_tmeta_rmeta_0]  cache_pool_tmeta
  [cache_pool_tmeta_rmeta_1]  cache_pool_tmeta
  [lvol0_pmspare]

a83d611a86 report: fix invalid memory read when reporting cache LV policy name
Fix regression caused by commit c2d4330f27
which removed the dm_pool_strdup for the cache policy name in
_cache_policy_disp report function.

This regression was hit with buffered reporting only (which is
used by default). The reason is that for buffered reporting, we're
iterating over LVs in VG (process_each_lv) while gathering
all the information that is needed for the report. In this case,
the LV's cache policy name has not been duped, but only the pointer
to the original VG buffer was stored. When the LV iteration finished,
the VG buffer was freed and any report to output called later
(dm_report_output call) accessed already freed VG data.

This didn't appear if unbuffered reporting was used (--unbuffered)
because in this case, the data were reported to output as
soon as they were processed, hence it was reported to output
before the VG data was freed.

124b490fe6 lvmlockd: update VG lock version earlier
Have commands send lvmlockd the update message
in vg_write instead of vg_commit, so that it's
not done while LVs are suspended.  If the vg_write
is not committed, and the seqno sent to lvmlockd
is not used, then lvmlockd can detect this when
the next update uses the same seqno.

796461a912 vgrename: use process_each_vg
Use process_each_vg() to lock and read the old VG,
and then call the main vgrename code.

When real VG names are used (not a UUID in place of the
old name), the command still pre-locks the new name
(when strcmp wants it locked first), before calling
process_each_vg on the old name.

In the case where the old name is replaced with a UUID,
process_each_vg now translates that UUID into the real
VG name, which it locks and reads.  In this case, we
cannot do pre-locking to maintain lock ordering because
the old name is unknown.  So, in this case the strcmp
based lock ordering is suppressed and the old name is
always locked first.  This opens a remote chance for
lock ordering conflict between racing vgrenames between
two names where one or both commands use the UUID.
