84b084c9b6 configure.ac: define DEFAULT_PROC_DIR in one place
Let's move proc into include/configure.h so this define can
be easily used across the source base.

Configure defines it - but ATM we do not provide any configure
option to change it - there should be no need to ever change it.

cd9b2b32aa configure: add --with-default-event-activaion=ON
Add new configurable option for building lvm2 with enable/disable
default autoactivation setting.

Might be useful for building i.e. rpms for systems where
this event_activation is not desired.

a0437225aa makefiles: avoid piping
Addressing problem for user of system without default bash shell.

As reported "set -o pipefail" is a bashism that causes the build to
fail when /bin/sh does not point to bash.
For example, this has been observed causing build failures
on Gentoo when /bin/sh is symlinked to /bin/dash.

Rule has been reworked and we started to use .DELETE_ON_ERROR to
ensure that with any errors during file generation, such invalid
file is automatically removed.

Rules were reworked to avoid using pipe and instead use temporary
files when necessary.
Printing lines with echo was replaced with POSIX recomended 'printf'
as proposed by reporter since handling of escape characters and
the "-n" flag for "echo" aren't portable across shells.

Also some build deps has been added.

a032e07578 makefiles: keep removing anchient files
Commit dropping lvmetad support 117160b27e
also removed cleaning of its generated files. However we need to keep
this functionality, otherwise we can leak them during various bisect.
Easier is to keep such rules forever.

Also commit c1ab9fb37f moved cmds.h to
include, so again keep it removed so it's not left there and in any
case could not misslead anyone.

1fb5107eea lvresize: better detection of BLKID_SUBLKS_FSINFO
Use configure detection instead of trying to directly include
blkid.h inside lvresize.c - where we do not pass in BLKID_CFLAGS
and since we actually do not need to use blkid there, introeduce
test variable HAVE_BLKID_SUBLKS_FSINFO and avoid trying to
use blkid.h in this place - this also fixes builing problem for
systems without blkid.h.

264827cb98 lvresize: add new options and defaults for fs handling
The new option "--fs String" for lvresize/lvreduce/lvextend
controls the handling of file systems before/after resizing
the LV.  --resizefs is the same as --fs resize.

The new option "--fsmode String" can be used to control
mounting and unmounting of the fs during resizing.

Possible --fs values:

checksize
  Only applies to reducing size; does nothing for extend.
  Check the fs size and reduce the LV if the fs is not using
  the affected space, i.e. the fs does not need to be shrunk.
  Fail the command without reducing the fs or LV if the fs is
  using the affected space.

resize
  Resize the fs using the fs-specific resize command.
  This may include mounting, unmounting, or running fsck.
  See --fsmode to control mounting behavior, and --nofsck to
  disable fsck.

resize_fsadm
  Use the old method of calling fsadm to handle the fs
  (deprecated.) Warning: this option does not prevent lvreduce
  from destroying file systems that are unmounted (or mounted
  if prompts are skipped.)

ignore
  Resize the LV without checking for or handling a file system.
  Warning: using ignore when reducing the LV size may destroy the
  file system.

Possible --fsmode values:

manage
  Mount or unmount the fs as needed to resize the fs,
  and attempt to restore the original mount state at the end.

nochange
  Do not mount or unmount the fs. If mounting or unmounting
  is required to resize the fs, then do not resize the fs or
  the LV and fail the command.

offline
  Unmount the fs if it is mounted, and resize the fs while it
  is unmounted. If mounting is required to resize the fs,
  then do not resize the fs or the LV and fail the command.

Notes on lvreduce:

When no --fs or --resizefs option is specified:
. lvextend default behavior is fs ignore.
. lvreduce default behavior is fs checksize
  (includes activating the LV.)

With the exception of --fs resize_fsadm|ignore, lvreduce requires
the recent libblkid fields FSLASTBLOCK and FSBLOCKSIZE.
FSLASTBLOCK*FSBLOCKSIZE is the last byte used by the fs on the LV,
which determines if reducing the fs is necessary.

ed48cb26a3 vdo: add vdoimport support
Add tool 'vdoimport' to support easy conversion of an existing VDO manager managed
VDO volumes into lvm2 managed VDO LV.

When physical converted volume is already a logical volume, conversion
happens with the VG itself, just with validation for extent_size, so
the virtually sized logical VDO volume size can be expressed in extents.

Example of basic simple usage:

vdoimport --name vg/vdolv  /dev/mapper/vdophysicalvolume

1cedbaf137 configure: support builds without versioning
Not all libc (like musl, uclibc dietlibc) libraries support full symbol
version resolution in runtime like glibc.
Add support to not generate symbol versions when compiling against them.

Additionally libdevmapper.so was broken when compiled against
uclibc. Runtime linker loader caused calling dm_task_get_info_base()
function recursively, leading to segmentation fault.

Introduce --with-symvers=STYLE option, which allows to choose
between gnu and disabled symbol versioning. By default gnu symbol
versioning is used.
__GNUC__ check is replaced now with GNU_SYMVER.
Additionally ld version script is included only in
case of gnu option, which slightly reduces output size.

Providing --without-symvers to configure script when building against
uclibc library fixes segmentation fault error described above, due to
lack of several versions of the same symbol in libdevmapper.so
library.

168e2ffbcd lvm: add readline alternative editline
LVM2 is distributed under GPLv2 only. The readline library changed its
license long ago to GPLv3. Given that those licenses are incompatible
and you follow the FSF in their interpretation that dynamically linking
creates a derivative work, distributing LVM2 linked against a current
readline version might be legally problematic.

Add support for the BSD licensed editline library as an alternative for
readline.

d9e8895a96 Allow dm-integrity to be used for raid images
dm-integrity stores checksums of the data written to an
LV, and returns an error if data read from the LV does
not match the previously saved checksum.  When used on
raid images, dm-raid will correct the error by reading
the block from another image, and the device user sees
no error.  The integrity metadata (checksums) are stored
on an internal LV allocated by lvm for each linear image.
The internal LV is allocated on the same PV as the image.

Create a raid LV with an integrity layer over each
raid image (for raid levels 1,4,5,6,10):

lvcreate --type raidN --raidintegrity y [options]

Add an integrity layer to images of an existing raid LV:

lvconvert --raidintegrity y LV

Remove the integrity layer from images of a raid LV:

lvconvert --raidintegrity n LV

Settings

Use --raidintegritymode journal|bitmap (journal is default)
to configure the method used by dm-integrity to ensure
crash consistency.

Initialization

When integrity is added to an LV, the kernel needs to
initialize the integrity metadata/checksums for all blocks
in the LV.  The data corruption checking performed by
dm-integrity will only operate on areas of the LV that
are already initialized.  The progress of integrity
initialization is reported by the "syncpercent" LV
reporting field (and under the Cpy%Sync lvs column.)

Example: create a raid1 LV with integrity:

$ lvcreate --type raid1 -m1 --raidintegrity y -n rr -L1G foo
  Creating integrity metadata LV rr_rimage_0_imeta with size 12.00 MiB.
  Logical volume "rr_rimage_0_imeta" created.
  Creating integrity metadata LV rr_rimage_1_imeta with size 12.00 MiB.
  Logical volume "rr_rimage_1_imeta" created.
  Logical volume "rr" created.
$ lvs -a foo
  LV                  VG  Attr       LSize  Origin              Cpy%Sync
  rr                  foo rwi-a-r---  1.00g                     4.93
  [rr_rimage_0]       foo gwi-aor---  1.00g [rr_rimage_0_iorig] 41.02
  [rr_rimage_0_imeta] foo ewi-ao---- 12.00m
  [rr_rimage_0_iorig] foo -wi-ao----  1.00g
  [rr_rimage_1]       foo gwi-aor---  1.00g [rr_rimage_1_iorig] 39.45

0b19387dae headers: use configure.h as 1st. header
Ensure configure.h is always 1st. included header.
Maybe we could eventually introduce gcc -include option, but for now
this better uses dependency tracking.

Also move _REENTRANT and _GNU_SOURCE into configure.h so it
doesn't need to be present in various source files.
This ensures consistent compilation of headers like stdio.h since
it may produce different declaration.

904e1e3d26 Place the first PE at 1 MiB for all defaults
. When using default settings, this commit should change
  nothing.  The first PE continues to be placed at 1 MiB
  resulting in a metadata area size of 1020 KiB (for
  4K page sizes; slightly smaller for larger page sizes.)

. When default_data_alignment is disabled in lvm.conf,
  align pe_start at 1 MiB, based on a default metadata area
  size that adapts to the page size.  Previously, disabling
  this option would result in mda_size that was too small
  for common use, and produced a 64 KiB aligned pe_start.

. Customized pe_start and mda_size values continue to be
  set as before in lvm.conf and command line.

. Remove the configure option for setting default_data_alignment
  at build time.

. Improve alignment related option descriptions.

. Add section about alignment to pvcreate man page.

Previously, DEFAULT_PVMETADATASIZE was 255 sectors.
However, the fact that the config setting named
"default_data_alignment" has a default value of 1 (MiB)
meant that DEFAULT_PVMETADATASIZE was having no effect.

The metadata area size is the space between the start of
the metadata area (page size offset from the start of the
device) and the first PE (1 MiB by default due to
default_data_alignment 1.)  The result is a 1020 KiB metadata
area on machines with 4KiB page size (1024 KiB - 4 KiB),
and smaller on machines with larger page size.

If default_data_alignment was set to 0 (disabled), then
DEFAULT_PVMETADATASIZE 255 would take effect, and produce a
metadata area that was 188 KiB and pe_start of 192 KiB.
This was too small for common use.

This is fixed by making the default metadata area size a
computed value that matches the value produced by
default_data_alignment.
