2fef22fa85 Set DM_UDEV_DISABLE_OTHER_RULES_FLAG for suspended DM devices in udev rules.
This is to avoid any scanning and processing of DM devices while they are in
suspended state (e.g. a rename while the device is suspended - a CHANGE event
is generated!). Otherwise, any scanning in the rules could end up with locking
the calling process until the device is resumed and so we don't receive a
notification about udev rules completion until then (and that effectively
locks out the process awaiting the notification!).

However, we still keep 'disk' and any 'subsystem' related udev rules running.
We trust these and these should check themselves whether a device is suspended
or not, not trying to run any scanning if it is.

a1cbc61c34 Add new dm_prepare_selinux_context fn to libdevmapper and use it throughout.
Detect existence of new SELinux selabel interface during configure.
Use new dm_prepare_selinux_context instead of dm_set_selinux_context.

We should set the SELinux context before the actual file system object creation.
The new dm_prepare_selinux_context function sets this using the selabel_lookup
fn in conjuction with the setfscreatecon fn. If selinux/label.h interface
(that should be a part of the selinux library) is not found during configure,
we fallback to the original matchpathcon function instead.

032a206a83 Allocate buffer for reporting functions dynamically to support long outputs.
Fix memory leak of field_id in _output_field function.

There's been a patch added recently to use dynamic allocation for metadata
tags buffer to remove the 4k limit (for writing metadata out). However, when
using reporting commands like vgs and lvs, we still need to fix libdm reporting
functions themselves to support such long outputs. So the buffer used in those
reporting functions is dynamic now.

The patch also includes a fix for field_id memory leak which was found in
the _output_field function.

e2bc7a277e Fix dm-mod autoloading logic to not assume control node is set correctly.
We can't rely on the fact that udev should prepare the node with right major
and minor number to trigger the module autoloading. We have to take into
account that the node could be missing or it could exist with improper
major and minor number assigned (e.g. from previous kernel versions in
an environment with static nodes and without udev). Make any corrections
if needed!

f3645e3f4b Fix udev rules to support udev database content generated by older rules.
This can happen with older rules (without support for synthesized events)
that are still part of initrd while using new udev rules in the system itself.

The consequence was that new udev rules incorrectly assumed that not having
DM_UDEV_PRIMARY_SOURCE_FLAG set always means the uevent is synthesized and
inappropriate (device is still not properly activated) and so it should be
ignored. However, initrd is not updated automatically while updating the
libdevmapper/udev rules in the system and so we end up with the rules not
detecting and setting crucial parts in the initrd environment and the rules
in the system that rely on the information that should have been stored in
udev db (which is incorrect in this configuration, of course).

The overall consequence is that the update of libdevmapper/lvm2 without
regenerating the initrd could end up with a boot failure! Ignoring the event
means removing any existing symlinks in /dev!

To fix this, increase udev rules version to make a difference. So from now on,
mark rules without proper support for synthesized events as
DM_UDEV_RULES_VSN="1" and 2 (or higher) if that support is included.

d818035d3a Reinstate detection of inappropriate uevent with DISK_RO set and suppress it.
We still need to detect this one! We're not so strict with CHANGE events as
with the ADD events while applying filters in the rules so this one would
pass and it would process the rules prematurely (because it appears *before*
the actual CHANGE event used when resuming a DM device while setting read-only
state at the same time).

d33d0b01bf 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.

c4cce91dce Use "nowatch" udev rule for known inappropriate devices.
For now, this is just a precaution. Normally, all the other (non-dm) rules
should check DM_UDEV_DISABLE_OTHER_RULES_FLAG and therefore avoid setting
any inotify watches as well. But let's make sure.

Support for final assignment of the "nowatch" rule (the use of ":=") will
appear in next udev release, v160. This should also work in previous udev
versions but the setting won't be sealed so any further OPTIONS="watch" will
always prevail there.

We may want to add more specific "nowatch" rules later if needed.

60e9c014a2 Fix udev rules to handle spurious events properly.
We can use DM_UDEV_PRIMARY_SOURCE_FLAG to identify the spurious events
and use it as an indication that the device has already been activated before
(and hence we can find this property in udev database).

WARNING: This change requires udev startup script to preserve udev database
from initrd. All the information stored there during activation of devices
is important for the initial "udevadm trigger --action=add" call that is
used in udev startup script. If not done this way, udev startup script needs
to define DM_UDEV_PRIMARY_SOURCE_FLAG=1 property for any ADD events it uses.

9dbad2f74d 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.

68c7b86df1 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.

14ad41a065 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.

a8ed16de33 Define {DM, LVM}_UDEV_DISABLE_CHECKING=1 env. variables for tests.

8e7c6b60fb 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.

7ab8b44b6c Disable udev rules on change event with DISK_RO=1.
There's a new change udev event generated since kernel 2.6.32 that
notifies userspace about a change in read-only attribute for block
devices (with DISK_RO=1 environment variable set).

We need to detect this and disable the rule application so the
meaning of this change event is not interchanged with the regular
change event used while resuming/renaming DM devices.

If there's anybody awaiting this notification in foreign rules,
he can still check for this env var and do the appropriate actions
separately.

88b0c82a0d 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).

01d3349587 Remove 'last_rule' from udev rules.
'last_rule' option has been removed from udev (version >= 147).

From now on, we require foreign rules to check and honor
ENV{DM_UDEV_DISABLE_OTHER_RULES_FLAG} instead. Foreign
rules should be skipped totally when this flag is set.

2c0df9552f Use udev flags in the rules and cleanup the rules:
- remove default permissions set in 95-dm-notify.rules (and add a hint in 12-dm-permissions.rules to set it by the user directly)
 - add multipath DM_ACTION=="PATH_FAILED" filter
 - remove unnecessary filters in the headers of the rules (we can simply use DM_UDEV_RULES_VSN instead)
 - fix symlink priorities in /dev/disk/ (snapshot volumes have low priority for FS UUID symlinks so it will not overwrite symlinks for the origin)

01b09aab43 mirror table generating code: Properly handle 'block_on_errors' and 'cluster' features
The device-mapper mirror CTR table has been changing over time.  This has
now been corrected to handle the old and new methods for invoking the
'block_on_errors' and 'cluster' features.  (The code that does this was
accidentally committed in the previous check-in.  This check-in finishes
the job.)

25d9591416 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.

ffa1b19e26 Add an "all" field which expands to all fields of the report type.
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.

a479761be5 Add checks for device names in dmsetup and show proper error messages.
Checks added for DM device names to allow only names < DM_NAME_LEN,
otherwise a part of lengthy name would be silently ignored and could
cause confusion while using dmsetup. Also, the name should not contain
'/' character, if it is used in context of creating a new device
or renaming the existing one (because we do not consider full path
to devices, they do not exist in filesystem yet) and appropriate error
messages are shown.
