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).

9c20c7af59 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.

9abf5e70be Add support for querying a device's inactive table. 
Currently this data is invisible to userspace.
Requires dm >= 4.16 (likely to be in linux 2.6.33).

b040e267a2 Cleanup of previous commit with latest changes in udev support code. 2009-10-26 21:38:35 +00:00
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.

3c74075fb1 '_emit_areas_line' returns 1 for success and 0 for failure. This always 
confuses me, so I've added a comment at the top of the function to
remind me of this.

I also found that 'mirror_emit_segment_line' was returning 0 (return_0)
on failure /and/ success.  It now returns 1 for success and 0 for failure -
just like '_emit_areas_line' and its calling function, '_emit_segment_line'.

systems without cookie support (older kernels).

8f26e18c13 Cluster log daemon (clogd): use LVM bitops in place of ext2 bitops 
Eliminate dependency on outside library, since the same functionality
exists in our tree.

[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.

d917c98cd8 Fix some clean rules, fix previous distclean checkin. 
In libdm/Makefile.in, we need to cleanup the symlink properly.
Adding to CLEAN_TARGETS seemed like the simplest way to do this
in the current build framework.  We could redo dependencies for
VERSIONED_SHLIB, but for now just add to CLEAN_TARGETS.

For scripts/Makefile.in, we should be adding to DISTCLEAN_TARGETS.
The generic rule in make.tmpl.in takes care of the cleanup.

ea0cdd28c1 Separate PV label attributes which do not need parse metadata when reporting. 
When reporting explicitly label attributes (pv_uuid for example), we do not
need to read metadata.

This patch separate the label fileds and removes scan_vgs_for_pvs
in process_each_pv() if not needed.

1a0280b313 Rename _parse_options() to _parse_fields() for naming consistency. 
In libdm, we only ever use 'fields', while the tools use 'options' and
'fields' interchangeably.

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.

1f1aaf43ea 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.

c48e40391b 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.

06b8fee542 Allow $DM_DEV_DIR envvar to override default of "/dev". 
* dmsetup/dmsetup.c (DEV_PATH): Remove definition.
(parse_loop_device_name): Add parameter: dev_dir.
Declare the "dev" parameter to be "const".
Use dev_dir, not DEV_PATH.  Handle the case in which dev_dir
does not end in a "/".
(_get_abspath): Declare "path" parameter "const", to match.
(_process_losetup_switches): Add parameter: dev_dir.
Pass dev_dir to parse_loop_device_name.
(_process_switches): Add parameter: dev_dir.
Pass dev_dir to _process_losetup_switches.
(main): Set dev_dir from the DM_DEV_DIR envvar, else to "/dev".
Call dm_set_dev_dir.
* lib/libdm-common.c (dm_set_dev_dir): Rewrite to be careful
about boundary conditions, now that dev_dir may be tainted.
* man/dmsetup.8: Mention $DM_DEV_DIR.

alongside the .so file.  This helps build dynamically linked LVM.

* lib/Makefile.in (VERSIONED_SHLIB): Define.
* make.tmpl.in (TARGETS): Append $(VERSIONED_SHLIB).
($(VERSIONED_SHLIB)): New rule.

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.
