7def56f1e4 [REGEX] Parse regexes that contain chars with value > 0x80
This is a long standing issue.  Fixed by casting a char value to
unsigned char before using it as an index into a bitset.

d87427446c Add check for kernel semaphore support and disable udev_sync if not available.
udev_sync feature requires semaphores (part of System V IPC) to be configured
in kernel (CONFIG_SYSVIPC). Check whether it is supported and if not, give
a warning message and disable udev synchronisation code automatically to
avoid any further error states and associated problems.

One should use the kernel with System V IPC support enabled or libdevmapper
with udev_sync feature disabled.

f89f7955fc Revert unsuccessful table load preparation in combined "create, load and resume" scenario.
There was missing "revert" call in _create_and_load_v4 fn while the preparation
for table load ends up with failure in create/load/resume sequence. Otherwise
we could end up with a device being created, but not table-loaded nor resumed.

Even though the table is not loaded and the device is not resumed at this
stage, we still need to synchronize with udev when calling the revert
"remove" ioctl - there's still a remove uevent generated! The "revert"
code does exactly that.

405c4a45d8 It's not enough to check for the kernel module in the case of cluster
mirrors, we must also check that the log daemon (cmirrord) is running.
The log module can be auto-loaded, but the daemon cannot be
"auto-started".  Failing to check for the daemon produces cryptic
messages that customers have a hard time deciphering.  (The system
messages do report that the log daemon is not running, but people
don't seem to find this message easily.)

Here are examples of what is printed when the module is available,
but the log daemon has not been started.

[root@bp-01 LVM2]# lvcreate -m1 -l1 -n lv vg
  Shared cluster mirrors are not available.

[root@bp-01 LVM2]# lvcreate -m1 -l1 -n lv vg -v

566515c095 Use early udev synchronisation and update of dev nodes for clustered mirrors.
When using clustered mirrors, we need device nodes to be created during
processing of device tree, not at its end like we normally do (we need to
access the nodes in cmirror prematurely). Therefore we use a new flag called
"immediate_dev_node" stored in deptree's load_properties struct to instruct the
device tree processing code to immediately synchronize with udev and flush all
stacked node operations so the nodes are prepared for use.

For now, the immediate_dev_node is used for clustered mirrors during
processing the dm_tree_preload_children code only. We can add more later if
needed.

ee83186ecc Add support for dm-mod module autoload.
A kernel patch is on its way for 2.6.35 adding support for dm-mod module
autoload. Udev v155 and higher is able to read static node information given
in modules.devname (extracted by depmod before) and will create such nodes
at its start. The first access to such node will load the module automatically
(directly in kernel) before the actual read/write operation is processed.

75e69cd1b2 Switch to use Requires.private for devmapper.pc and lvm2app.pc
Use Requires.private: instead of Libs.private:
Use UDEV_PC and SELINUX_PC for Require.private:

It looks like usage of Requires.private is prefered from Libs.private.
However pkg-config documentation is really poor here. But here is
short outcome:

There is a difference in Libs.private: and Requires.private: where
we specify libselinux instead of  -lselinux -lsepol.

We leave resolving of query like 'pkg-config --libs --static devmapper'
on taking proper selinux and udev libs to their .pc files instead of
hardcoding them into our .pc file which is might give incorrect answer.
- i.e. dependency of libselinux package might change and we may return
wrong list of linked libraries.

942d6ef29f Add support for new IMPORT{db} udev rule.
This rule appeared in udev v152 and it helps us to support spurious events
where we didn't have any flags set (events originated in udevadm trigger
or the watch rule). These flags are important to direct the rule application.
Now, with the help of this rule, we can regenerate old udev db content.
To implement this correctly, we need to flag all proper DM udev events with
DM_UDEV_PRIMARY_SOURCE_FLAG. That happens automatically for all ioctls
generating events originated in libdevmapper.

- adds INSTALL_PROGRAM for executable, uses $(INSTALL)
- adds INSTALL_DATA for non-executable data, uses ($INSTALL)
- adds INSTALL_WDATA for writable non-executable data, uses ($INSTALL)
- adds configure option --enable-write_install - to support
  installatin of writable files used by distribution
- replaces usage of ifeq @LIB_SUFFIX@ with $(LIB_SUFFIX)

- installs .a files to $(usrlibdir) instead of $(libdir)
- installs all static binaries to $(staticdir)
- create .so links for devel package in $(usrlibdir) instead of
  $(libdir)

c737d34804 Use vpath instead of VPATH.
Usage of VPATH makes troubles when used within $(builddir).
Not only source files are being found through VPATH,
but targets as well. (make --debug=v)

Thus if user builds the code in $(srcdir) and also in some $(builddir)
he gets mangled results as some generated files (i.e. .export.sym)
are 'reused' from $(srcdir) instead of $(builddir).

This patch switches to use vpath were we could explicitly name
suffixes that should be looked via vpath - we must take care,
we do not generate files with these suffixes:

ac3691f70e Add support for ioctl's DM_UEVENT_GENERATED_FLAG.
We need to know whether we should wait for any uevent or not when
using udev_sync. A kernel patch was posted recently that changed the
way uevents are sent on dm device resume - it is sent only if the
device has been suspended before. There's also a new DM_UEVENT_GENERATED_FLAG
in the ioctl to notify userspace whether the event was generated.

If the uevent was not generated (e.g. the situation where the device is
*not* suspended and we call a resume), we just call dm_udev_complete
explicitly from within libdevmapper itself to prevent infinite waiting
while trying to synchronise with udev processing.

49b95a5e21 Off-by-one count was causing not all the mirror table parameters
that were necessary to be passed on to userspace.

The cluster mirror table (log portion only) used to look like this:
        clustered-disk <parm_count> <disk> <region_size> <uuid> \
                        [[no]sync] [block_on_error]
Now it looks like this:
        userspace <parm_count> <uuid> clustered-disk <disk> <region_size> \
                        [[no]sync]

So, there is one extra argument in the latter case - this was
unaccounted for.

aa6f4e51a7 Add support for "snapshot-merge" target.
Introduces new libdevmapper function dm_tree_node_add_snapshot_merge_target

Verifies that the kernel (dm-snapshot) provides the 'snapshot-merge'
target.

Activate origin LV as snapshot-merge target.  Using snapshot-origin
target would be pointless because the origin contains volatile data
while a merge is in progress.

Because snapshot-merge target is activated in place of the
snapshot-origin target it must be resumed after all other snapshots
(just like snapshot-origin does) --- otherwise small window for data
corruption would exist.

Ideally the merging snapshot would not be activated at all but if it is
to be activated (because snapshot was already active) it _must_ be done
after the snapshot-merge.  This insures that DM's snapshot-merge target
will perform exception handover in the proper order (new->resume before
old->resume).  DM's snapshot-merge does support handover if the reverse
sequence is used (old->resume before new->resume) but DM will fail to
resume the old snapshot; leaving it suspended.

To insure the proper activation sequence dm_tree_activate_children() was

d2b43c4b34 Add support to disable udev checking: DM_UDEV_DISABLE_CHECKING=1 env. variable.
Sometimes it is really needed to switch off udev checking and the warnings we show when
we detect that udev has not done its job right - the messages like "Udev should have done
this and that. Falling back to direct node creation/removal. " etc.

This would be especially handy while setting DM_DEV_DIR env var that could be set to a
different location than standard /dev (udev can't create nodes/symlinks out of that one
directory that is configured into udevd). The exact same situation happens while we're
running our tests.

584d1fb7d1 Support udev flags even when udev_sync is disabled or not compiled in.
This provides better support for environments where udev rules are installed
but udev_sync is not compiled in (however, using udev_sync is highly
recommended). It also provides consistent and expected functionality even
when '--noudevsync' option is used.

There is still requirement for kernel >= 2.6.31 for the flags to work though
(it uses DM cookies to pass the flags into the kernel and set them in udev
event environment that we can read in udev rules).

rules should be skipped totally when this flag is set.

Peter Rajnoha
421671b1c2 Several changes to udev support code:
- we have these levels when the udev rules are processed:
   10-dm.rules --> [11-dm-<subsystem>.rules] --> [12-dm-permissions.rules] -->
   13-dm-disk.rules --> [...all the other foreign rules...] --> 95-dm-notify.rules

 - each level can be disabled now by
   DM_UDEV_DISABLE_{DM, SUBSYSTEM, DISK, OTHER}_RULES_FLAG

 - add DM_UDEV_DISABLE_DM_RULES_FLAG to disable 10-dm.rules

 - add DM_UDEV_DISABLE_OTHER_RULES_FLAG to disable all the other (non-dm) rules.
   We cutoff these rules by using the 'last_rule', so this one should really be
   used with great care and in well-founded situations. We use this for lvm's
   hidden and layer devices now.

 - add a parameter for add_dev_node, rm_dev_node and rename_dev_node so it's
   possible to switch on/off udev checks

 - use DM_UDEV_DISABLE_DM_RULES_FLAG and DM_UDEV_DISABLE_SUBSYSTEM_RULES_FLAG
   if there's no cookie set and we have resume, remove and rename ioctl.
   This could happen when someone uses the libdevmapper that is compiled with
   udev_sync but the software does not make use of it. This way we can switch
   off the rules and fallback to libdevmapper node creation so there's no
   udev/libdevmapper race.

Eliminate dependency on outside library, since the same functionality

[It is important that the bitops work in the same way, as the bitmaps
must remain backwards compatible.  I haven't tested every architecture,
but the x86* archs work.  My test involved using the old ext2fsprogs
bitops, memcpy'ing the bits over to the LVM bitset array and ensuring
that only the bits set via the old methods were set.]

12ca060e9f Support crypt segment in libdevmapper tree.
- it can support multiple segments, but note that
to work properly, correct IV (initialization vector)
offset parameter must be set properly.

Because most usage of IV start offset is when we join
several crypto segments together (so iv_offset is the segment
start offset), DM_CRYPT_IV_DEFAULT is defined to simplify
the process.

Function accepts the string in cipher agrument (already
including chainmode and iv type; chainmode and iv parameters are NULL
in this case) or user can provide split parameters which will
join into dm-crypt cipher specification "cipher-chainmode-iv".

All these parameters must be supplied in correct dm-crypt format.

For scripts/Makefile.in, we should be adding to DISTCLEAN_TARGETS.

In libdm, we only ever use 'fields', while the tools use 'options' and

Ideally it would be good to use 'fields' consistently everywhere.
However, 'options' most likely comes from the tool commandline '-o' and
'--options' which cannot be changed.

For example in LVM2, "pv_all" gives all PV fields.
"seg_all" gives all LV segment fields.

"all" gives all fields of the final report type.  I think this is more
useful than just adding the current prefix.

So "lvs -o seg_all" gives all the LV segment fields, whilst
"lvs --segments -o all" adds in LV and VG fields too.

"lvs -o all -O vg_name" has report type LVS+VGS so includes all LV and all
VG fields.

Jonathan Earl Brassow
d6d4661517 - The automatic log module loading patch proposed for the upstream kernel

5469414bf8 Timeout event implementation:
The daemon side of this is mostly the same as the patch I sent out.  To select
a timeout period different than the default and to get the timeout period,
I added two library calls, dm_set_event_timeout() and dm_get_event_timeout().
If people are against them, the other option is to tack extra arguments onto
dm_regiser_for_event() and dm_get_registered_device().  I also added a
-t option to dmevent, so people can try out timeouts.

cd4355d8f4 o stick multilog into the dm-event lib and dmeventd code again
o more tweaks to libmultilog calls - the api isn't set in stone yet, so
   don't get too comfortable.
 o not sure the dmeventd in device-mapper/dmeventd works - i've been using
   the one in lib/event/
 o currently both daemons are set to log only to syslog

Kernel driver has a version number (stored in kernel/VERSION).
