WHATS_NEW_DM: update
2023-02-13 01:50:09 +03:00
Improve parallel creation of /dev/mapper/control device node.
udev: import previous results of blkid when in suspended state Follow-up for e10f67e91728f1e576803df884049ecbd92874d0. The commit e10f67e91728f1e576803df884049ecbd92874d0 tries to keep device node symlinks even if the device is in the suspended state. However, necessary properties that may previously obtained by the blkid command were not imported at least in the .rules file. So, unless ID_FS_xyz properties are imported by another earlier .rules file, the device node symlinks are still lost when event is processed in the suspended state. Let's explicitly import the necessary properties. RHBZ: https://bugzilla.redhat.com/show_bug.cgi?id=2158628 GHPR: https://github.com/lvmteam/lvm2/pull/105
2023-02-01 18:28:12 +03:00
Import previous ID_FS_* udev records in 13-dm-disk.rules for suspended DM dev.
udev: remove rule for explicit creation of /dev/mapper/control We used KERNEL=="device-mapper", NAME="/dev/mapper/control" udev rule to create the /dev/mapper/control file. The "NAME" rule should be only used to rename network devices, otherwise udev issues a warning message. The device-mapper driver has proper DEVNAME=/dev/mapper/control propagated in the uevent environment when it is loaded so we don't need further instruction on where to create the node - udev knows already. Also, these days, it is created directly by kernel inside devtmpfs. This makes the NAME="/dev/mapper/control" rule completely obsolete.
2023-02-02 17:30:30 +03:00
Remove NAME="mapper/control" rule from 10-dm.rules to avoid udev warnings.

Version 1.02.189 - 22nd December 2022
post-release
2022-11-10 16:21:57 +03:00
=====================================
dmsetup: fix udev event handling for create With newer kernels (>5.13) DM_CREATE no longer generates uevent for DM devices without table. There are even no sysfs block device entries in such case, although device has asigned major:minor and it is being listed by 'dmsetup info'. So this patch calculates amount of 'table' lines and in case no table line comes from cmdline or stdin - waiting on cookie is avoided generically instead of disabling just case with option --notable - which then also skipped handling of an option --addnodeoncreate (which is however historical and should be avoided) As a result there should be no leaking udev cookies and endlessly waiting commands like this: dmsetup create mytestdev </dev/null
2022-11-25 17:45:47 +03:00
Improve 'dmsetup create' without given table line with new kernels.

Version 1.02.181 - 20th October 2021
====================================
libdm: dmsetup measure support for IMA Add support for DM_IMA_MEASUREMENT_FLAG with DM_TABLE_STATUS_CMD. This feature requires DM version 4.45 (5.15+ kernels)
2021-07-13 04:06:04 +03:00
Add IMA support with 'dmsetup measure' command.
libdm: support DM_NAME_LIST_FLAG Kernel patch 8b638081bd4520f63db1defc660666ec5f65bc15 introduced support to return UUID in DM_LIST_DEVICES_CMD. Useful when asking for UUID of each device where the list could be now returned directly with NAME && UUID for each device. Returning UUID is done in backward-compatible way. There's one unused 32-bit word value after the event number. This patch sets the bit DM_NAME_LIST_FLAG_HAS_UUID if UUID is present and DM_NAME_LIST_FLAG_DOESNT_HAVE_UUID if it isn't (if none of these bits is set, then we have an old kernel that doesn't support returning UUIDs). The UUID is stored after this word. The 'next' value is updated to point after the UUID, so that old version of libdevmapper will skip the UUID without attempting to interpret it.
2021-09-22 22:22:59 +03:00
Add defines DM_NAME_LIST_FLAG_HAS_UUID, DM_NAME_LIST_FLAG_DOESNT_HAVE_UUID.
libdm: enhance tracking of activated LVs Existing mechanism was not able to trace root volume issue. Simplify the functionality by using simply using activated flag and trace the dtree in reverse order.
2021-09-12 22:15:31 +03:00
Enhance tracking of activated devices when preloading dm tree.
cache: fix parentheses for migration_threshold When generating table line for cache target line, the estimation of added arguments was incorrectly calculated as the evaluation order of "?" is made after "+". However the result was 'masked' by the Reported-by: Jian Cai jcai19
2021-09-11 00:02:09 +03:00
Fix bug in construction of cache table line (regression from 1.02.159).

Version 1.02.171 - 26th March 2020
==================================
dm: remove created devices on error path DM tree keeps track of created device while preloading a device tree. When fail occures during such preload, it will now try to remove all created and preloaded device. This makes it easier to maintain stacking of device, since we do not need to check in-depth for existance of all possible created devices during the failure.
2020-10-16 21:58:58 +03:00
Try to remove all created devices on dm preload tree error path.
WHATS_NEW_DM: update

=====================================
libdm: support device RELOAD with maj:min and devname set When devices are created - we were not giving meaning error messages when the failure happened on 'reload' part of creation. With this patch we are now able to report both name and major:minor. Enhancment is most visible with 'crypto' devices, which are using 'secure' memory erase bit.
2019-12-10 15:28:16 +03:00
Enhance error messages for device creation.

====================================
dm: fix compilation of dmsetup Fix: 889c88e9dab33195efc4dc0400a4b0aaa3383948 Use correct enum DM_DEVICE_GET_TARGET_VERSION.
2019-10-21 17:31:53 +03:00
Add support for DM_DEVICE_GET_TARGET_VERSION.
dmsetup: debug print Udev debugging is a bit tricky, so to more easily pair cookie ID, which is the lowest 16 bit - print cookie as hexa number. This simplify pairing of processed cookies while the 'higher bit flags' are changed for the same cookie.
2019-08-17 00:49:38 +03:00
Add debug of dmsetup udevcomplete with hexa print DM_COOKIE_COMPLETED.
exported_symbols: comment old symbols Fix versioning for updated symbols dm_stats_create_region and dm_stats_create_region. Only the latest symbol should have global entry. Since I'm not sure what is currenlty the best option for old symbols - we added support for easy commenting of them (so we do not lose information when the symbol appeared for the first time.) Note: some old already deleted symbols should have been restored as comments.
2019-07-30 16:31:51 +03:00
Fix versioning of dm_stats_create_region and dm_stats_create_region.

cache: support no_discard_passdown Recent kernel version from kernel commit: de7180ff908b2bc0342e832dbdaa9a5f1ecaa33a started to report in cache status line new flag: no_discard_passdown Whenever lvm spots unknown status it reports: Unknown feature in status: So add reconginzing this feature flag and also report this with 'lvs -o+kernel_discards' When no_discard_passdown is found in status 'nopassdown' gets reported for this field (roughly matching what we report for thin-pools).
2019-06-05 15:31:34 +03:00
Parsing of cache status understand no_discard_passdown.
dm: migration_threshold for old linked tools Just like with precending lvm2 device_mapper patch, ensure that old users of libdm will also get fixed migration threshold for caches.
2019-01-20 13:45:27 +03:00
Ensure migration_threshold for cache is at least 8 chunks.

Version 1.02.155 - 18th December 2018
=====================================
libdm: use libdm header User libdm header file.
2018-12-14 15:11:48 +03:00
Include correct internal header inside libdm list.c.
libdm: print params only for ioctls using them When preparing ioctl buffer and flatting all parameters, add table parameters only to ioctl that do process them. Note: list of ioctl should be kept in sync with kernel code.
2018-11-16 17:57:15 +03:00
Enhance ioctl flattening and add parameters only when needed.
libdm: add DM_DEVICE_ARM_POLL Expose DM_DEVICE_ARM_POLL via standard API enum.
2018-11-16 17:58:16 +03:00
Add DM_DEVICE_ARM_POLL for API completness matching kernel.
libdm: do not add params for resume and remove DM_DEVICE_CREATE with table is doing several ioctl operations, however only some of then takes parameters. Since _create_and_load_v4() reused already existing dm task from DM_DEVICE_RELOAD it has also kept passing its table parameters to DM_DEVICE_RESUME ioctl - but this ioctl is supposed to not take any argument and thus there is no wiping of passed data - and since kernel returns buffer and shortens dmi->data_size accordingly, anything past returned data size remained uncleared in zfree() function. This has problem if the user used dm_task_secure_data (i.e. cryptsetup), as in this case binary expact secured data are erased from main memory after use, but they may have been left in place. This patch is also closing the possible hole for error path, which also reuse same dm task structure for DM_DEVICE_REMOVE.
2018-11-16 17:54:09 +03:00
Do not add parameters for RESUME with DM_DEVICE_CREATE dm task.
pre-release
2019-06-07 17:32:02 +03:00

=================================
dmeventd: base vdo plugin Introduce VDO plugin for monitoring VDO devices. This plugin can be used also by other users, as plugin checks for UUID prefix 'LVM-' and run lvm actions only on those devices. Non LVM- device are only monitored and log warnings when usage threshold reaches 80%.

====================================
cleanup: call uname once Call uname() once and keep result for mirror use-case.
2018-03-27 22:07:13 +03:00
Reuse uname() result for mirror target.
libdm: enhance mounted fs detection btrfs is using fake major:minor device numbers. try to be smarter and detect used node via DM device name. This shortens delays, where i.e. lvm2 is asked to deactivate volume with mounted btrfs as such operation is not retryed and user is informed about device being in use.
2018-03-20 13:13:22 +03:00
Recognize also mounted btrfs through dm_device_has_mounted_fs().
libdm-stats: fix error messages When function dm_stats_populate() returns 0 it's an error and needs log_error() message - function can't have 'success' returning 0 or error without reasons.
2018-03-14 23:00:46 +03:00
Add missing log_error() into dm_stats_populate() returning 0.
dmstatus: check nr_regions ahead of find call Prevent call of dm_stats_populate(), when there has been no stats region detected for a DM device. Such skip is evaluated as 'correct' visit of stats call and not causing 'dmstats' command failure.
2018-03-14 23:01:22 +03:00
Avoid calling dm_stats_populat() for DM devices without any stats regions.
libdm: support for DM_DEBUG_WITH_LINE_NUMBERS For any libdm tool using default debugging function allow to show source filename and code line number when this functionality is available.
2018-03-14 20:08:16 +03:00
Support DM_DEBUG_WITH_LINE_NUMBERS envvar for debug msg with source:line.
thin: pass environment to scripts When dmeventd thin plugin forks a configurable script, switch to use execvp to pass whole environment present to dmeventd - so all configured paths present at dmeventd startup are visible to script. This was likely not a problem for common user enviroment, however in test suite case variable like LVM_SYSTEM_DIR were not actually used from test itself but rather from a system present lvm.conf and this may have cause strange behavior of a testing script.
2018-03-05 17:09:16 +03:00
Configured command for thin pool threshold handling gets whole environment.
libdm-stats: correct checking of dm_snprintf error Function dm_snprintf returns -1 on error, while 0 is still considered valid result code so correcting error path testing.
2018-02-12 12:27:16 +03:00
Fix tests for failing dm_snprintf() in stats code.
libdm: accept mirror status with userspace word in the line Just making sure the parser will not stop - although greater level of support needs to be added (Describing doc seems to be missing however).
2018-02-01 22:53:39 +03:00
Parsing mirror status accepts 'userspace' keyword in status.
libdm: Introduce dm_malloc_aligned
2018-01-09 23:25:43 +03:00

Version 1.02.146 - 18th December 2017
=====================================
libdm: avoid checking status on activation Variable props.send_messages has 3 states and was not used properly here. Activation in this moment does not need to verify thin-pool status as that has been already checked on preload. So only if there are some real messages (value 2) call function for sending them.
2017-12-07 19:52:01 +03:00
Activation tree of thin pool skips duplicated check of pool status.
libdm: support for replicator target is dropped Replicator never really existed in upstream kernel and its support got deprecated. Also its support never got finished so no code is supposed to be using it anyway. Libdm symbols are remaining, just the implementation will always return failure - so any user of: dm_tree_node_add_replicator_dev_target() dm_tree_node_add_replicator_target(). will now always recieve error message.
2017-12-04 17:27:05 +03:00
Remove code supporting replicator target.
libdm: watch for failing _info_by_dev Separate handling of error code from _info_by_dev. This error can only happeng when we are running out of memory. In such case there is urgent need to stop any futher proceeding of command and run to error ASAP.
2017-12-04 17:05:44 +03:00
Do not ignore failure of _info_by_dev().
libdm: preload propagates delayed resume Propagate delayed resume at least for preload case in a simple way. Currently PVMOVE depends on internal logic where 'mirror' with corelog is 'possible' PVMOVE. In such case resume of 'created' node is 'delayed'. This is mostly an ugly internal hack - but for the moment being when we add propagation for preload - it does work reasonable. TODO: provide standard API and avoid this internal 'guessing'.
2017-11-24 15:57:22 +03:00
Propagate delayed resume for pvmove subvolumes.
dmsetup: hide integrity encryption keys on table output
2017-11-10 15:55:04 +03:00
Suppress integrity encryption keys in 'table' output unless --showkeys supplied.

====================================
systemd: remove Install sections from socket-activated services We always preferred and recommended socket activation for our services so remove the Install section in related .service units which are unused in this case and keep only the Install section in associated .socket units. Signed-off-by: Bastian Blank <waldi@debian.org>
2017-11-01 17:25:54 +03:00
Keep Install section only in dm-event.socket systemd unit.
dmsetup: Add unknown device error to dmsetup status. Treat status the same way as info if provided device name doesn't exist.
2017-10-26 19:47:13 +03:00
Issue a specific error with dmsetup status if device is unknown.
libdm: fix typo in libdevmapper.pc Fixing name for RT libraries and using RT_LIBS.
2017-10-18 01:03:08 +03:00

Version 1.02.144 - 6th October 2017
===================================
dmeventd: schedule exit on break When dmeventd receives SIGTERM/INT/HUP/QUIT it validates if exit is possible. If there was any device still monitored, such exit request used to be ignored/refused. This 'usually' worked reasonably well, however if there is very short time period between last device is unmonitored and signal reception - there was possibility such EXIT was ignored, as dmeventd has not yet got into idle state even commands like 'vgchange -an' has already finished. This patch changes logic towards scheduling EXIT to the nearest point when there is no monitored device. EXIT is never forgotten. NOTE: if there is only a single monitored device and someone sends SIGTERM and later someone uses i.e. 'lvchange --refresh' after unmonitoring dmeventd will exit and new instance needs to be started.
2017-10-04 14:58:21 +03:00
Schedule exit when received SIGTERM in dmeventd.
blkdeactivate: also try to unmount /boot on blkdeactivate -u if on top of supported device There's nothing special about /boot other than it's used during boot. But when blkdeactivate is called either on all devices or including a device where the /boot is on top, we should also include this mount point when doing unmount before deactivation of supported devices.
2017-09-21 16:23:24 +03:00
Also try to unmount /boot on blkdeactivate -u if on top of supported device.
blk-availability: use blkdeactivate -r wait in blk-availability systemd service/initscript
2017-09-21 16:10:23 +03:00
Use blkdeactivate -r wait in blk-availability systemd service/initscript.
blkdeactivate: add blkdeactivate -r wait option to wait for MD resync/recovery/reshape The new blkdeactivate -r|mdraidoption wait causes blkdeactivate to wait for any resync/recovery/reshape that is currently in progress before deactivating the device. If this option is used, blkdeactivate calls mdadm -W|--wait before mdadm -S|--stop.
2017-09-21 16:04:45 +03:00
Add blkdeactivate -r wait option to wait for MD resync/recovery/reshape.
blkdeactivate: fix blkdeactivate regression with failing DM/MD devs deactivation Revert dc50f2f4a03dd50c5e2411a258095484555421e9. We're canonicalizing/escaping the names here and we're reusing the variable name so the code doesn't need to use extra variables and further assignments that may confuse us. Let's keep the code simple. The local name=(...$name) is not the same as local name name=(...$name) (I know various code-checking tools fuss about this and recommend the 2nd way, but let's ignore those tools' nitpicking here please.)
2017-09-21 14:39:52 +03:00
Fix blkdeactivate regression with failing DM/MD devs deactivation (1.02.142).
blkdeactivate: fix --{dm,lvm,mpath}options option name recognition There was a typo in blkdeactivate --dmoption/--lvmoption/mpathoption, it had missing "s" at the end and it was not recognized properly, only short names for the options (-d/-l/-m).
2017-09-21 18:03:42 +03:00
Fix typo in blkdeactivate's '--{dm,lvm,mpath}options' option name.
libdm: fix parentheses in assignment + comparison As reported, fix incorrect placement of parentheses. TODO: add testing code.
2017-09-20 15:21:38 +03:00

Version 1.02.143 - 13th September 2017
======================================
libdm: fix errpath for control node creation When control node failure happens, umask was not restored. Fix it by using common exit path.
2017-08-22 11:19:40 +03:00
Restore umask when creation of node fails.
dmsetup: Add --concise to dmsetup create. Add the new concise format to dmsetup create, either as a single command-line parameter or from stdin. Based on patches submitted by Enric Balletbo i Serra <enric.balletbo@collabora.com>.
2017-08-04 21:38:34 +03:00
Add --concise to dmsetup create for many devices with tables in one command.
ioctl: Allow minor without major. There's no need to insist on a major number being supplied when the code's going to override it if it's wrong anyway.
2017-08-04 16:45:20 +03:00
Accept minor number without major in library when it knows dm major number.
dmsetup: Add concise table output format. Create a new table output format that concisely shows multiple devices on one line. dmsetup table --concise [device...] <dev_name>,<uuid>,<flags>[,<table>]*[;<dev_name>,<uuid>,<flags>[,<table>]*]* Table lines are separated by commas. Devices are separated by semi-colons. Flags is currently 'ro' or 'rw' (and might be extended in a yet-to-be-defined way in future). Any comma, semi-colon or backslash within a field is quoted by a preceding backslash. The format can later be supplied as input to dmsetup or even to the booting kernel as an alternative way to set up devices. Based on patches submitted by Enric Balletbo i Serra <enric.balletbo@collabora.com>.
2017-07-25 03:13:14 +03:00

=================================
udev: also create /dev/disk/by-part{label,uuid} and gpt-auto-root symlinks The blkid we call in 13-dm-disk.rules also returns identifiers for partitions based on which the /dev/disk/by-part{uuid,label} and gpt-auto-root symlinks should be created in the same manner as we already create symlinks for filesystem labels and uuids. This is because we handle blkid calls and symlink creation under /dev/disk ourselves in our 13-dm-disk.rules for device-mapper devices for us to have more control over this process. See also https://lists.freedesktop.org/archives/systemd-devel/2017-July/039220.html and original report http://tracker.ceph.com/issues/19489 for the exact case where these symlinks were missing.

Version 1.02.141 - 28th June 2017
=================================
libdm: fix initialization of head for reused structure Dmeventd reuses 'dm_task' struct for some STATUS operation, but due to missing reinitization of dm_task target list, it has caused misprocesing of recieved events as the parsed target has been simply added to the list of existing status and cause multiple actions being called for single event.
2017-06-26 19:22:40 +03:00
Fix reusing of dm_task structure for status reading (used by dmeventd).
libdm: implement dm_percent_to_round_float Add function to adjust printing of percent values in better way. Rounding here is going along following rules: 0% & 100% are always clearly reported with .0 decimal points. Values slightly above 0% we make sure a nearest bigger non zero value with given precission is printed (i.e. 0.01 for %.2f will be shown) For values closely approaching 100% we again detect and adjust value that is less then 100 when printed. (i.e. 99.99 for %.2f will be shown). For other values we are leaving them with standard rounding mechanism since we care mainly about corner values 0 & 100 which need to be printed precisely.
2017-06-24 14:24:26 +03:00
Add dm_percent_to_round_float for adjusted percentage rounding.
dmeventd: improve more raid status reporting When we want to report primary leg failure, check for intial 'a', since otherwice 'Aa idle' is normally visible. Also reset array of bit flags marking dead devices, once plugin detects raid is in sync.
2017-06-24 01:06:12 +03:00
Reset array with dead rimage devices once raid gets in sync.
raid: plugin does not to use --config Functionality of ignore suspend devices is already granted by: lvm2_disable_dmeventd_monitoring() -> init_run_by_dmeventd() -> init_ignore_suspended_devices(). In fact plugins should never use --config because it has some unpleasant technical issues.
2017-06-23 22:15:37 +03:00
Drop unneeded --config option from raid dmeventd plugin.
libdm: workarounds reported raid status info Current existing kernels reports status sometimes in weird form. Instead of showing what is the exact progress, we need to estimate this in-sync state from several surrounding states. Main reason here is to never report 100% sync state for a raid device which will be undergoing i.e. recovery.
2017-06-16 14:20:47 +03:00
dm_get_status_raid() handle better some incosistent md statuses.
libdm: allow truncated files in dm_stats_update_regions_from_fd() It's not an error to attempt to update regions from an fd that has been truncated (or otherwise no longer has any allocated extents): in this case, the call should remove all regions corresponding to the group, and return an empty region table.
2017-06-07 21:21:10 +03:00
Accept truncated files in calls to dm_stats_update_regions_from_fd().
dmeventd: restore multiple warnings With recent updates for thin pool monitoring in version 169 we lost multiple WARNINGs to be printed in syslog, when pool crossed 80%, 85%, 90%, 95%, 100%. Restore this logic as we want to keep user informed more then just once when 80% boundary is passed.
2017-04-19 20:57:00 +03:00
Restore Warning by 5% increment when thin-pool is over 80% (1.02.138).

Version 1.02.138 - 28th March 2017
==================================
Support additional raid5/6 configurations.
libdm: maintain binary interface for new FEATURE flag Older library version was not detecting unknown 'feature' bits and could let start target without needed option. New versioned symbol now checks for supported feature bits. _Base version keeps accepting only previously known features and mask/ignores unknown bits. NB: if the older binary passed in 'random' bits, it will not get metadata2 by chance. New linked binary get new validation function. Library user is required to not pass 'trash' for unsupported bits, as such calls will be rejected.
2017-02-25 00:41:42 +03:00
Provide dm_tree_node_add_cache_target@base compatible symbol.
libdm: support cache metadata2 feature flag Dm cache target version 1.10 introduces new cache metadata format (upstream kernel >=4.11). New format is enable by passing new target feature flag metadata2. Interace side on libdm uses DM_CACHE_FEATURE_METADATA2. This feature bit is now also recognized on status and set in 'feature_flags' field of dm_status_cache structure. Code also adds check for 'highest' supported feature flag bit. So it rejects properly any 'unknown' feature bit set by application.
2017-02-24 01:38:06 +03:00
Support DM_CACHE_FEATURE_METADATA2, new cache metadata format 2.
libdm: better code to enforce writethrough Better code to enforce writethrough caching for cleaner policy. Only check for cleaner when DM_CACHE_FEATURE_PASSTHROUGH or DM_CACHE_FEATURE_WRITEBACK is set.
2017-02-24 01:35:40 +03:00
Improve code to handle mode mask for cache nodes.
libdm: passthrough checks traling space char When checking for passthrough length, check also for extra ' ' char just like with other feature strings.
2017-02-26 21:31:06 +03:00
Cache status check for passthrough also require trailing space.
mem: add extra mem pages for pthread stack Some archs can use even 64K pages and then lvm2 runs into trouble if the stack is 'too small' to fit extra page capturing stack overwrite. So when lvm2 limits stack - add extra mem page - be it 4K or 64K. Relates to ppc64le bug: https://bugzilla.redhat.com/1387279
2017-02-11 20:14:00 +03:00
Add extra memory page when limiting pthread stack size in dmeventd.
libdm: avoid resume if preloaded device is smaller When we preload device with smaller size, we avoid its resume, so later suspend/resume of full device tree my process all existing in flight bios. Also update comment and avoid using confusing opposite meaning.
2017-02-10 21:57:04 +03:00
Avoids immediate resume when preloaded device is smaller.
pre-release Removing some unused new lines and changing some incorrect "can't release until this is fixed" comments. Rename license.txt to make it clear its merely an included file, not itself a licence.
2017-03-28 17:28:53 +03:00
Do not suppress kernel key description in dmsetup table output for dm-crypt.
dmeventd_thin: enable support for external command With this commit we start to support configurable action from thin-pool monitoring via 'dmeventd/thin_command'
2017-01-21 00:54:20 +03:00
Support configurable command executed from dmeventd thin plugin.
libdm: add human R|readable units When showing sizes with 'H|human' units we do use standard rounding. This however is confusing users from time to time, when the printed number uses some biger units i.e. GiB and there is just tiny fraction of space missing. So here is some real-life example with new 'r' unit. $lvs LV VG Attr LSize Pool Origin lvol0 vg -wi-a----- 1.99g lvol1 vg -wi-a----- <2.00g lvol2 vg -wi-a----- <2.01g Meaning is - lvol1 has 'slightly' less then 2.00g - from sign '<' user can be aware the LV doesn't have full 2.00GiB in size so he will be less surpriced allocation of 2G volume will not succeed. $ vgs VG #PV #LV #SN Attr VSize VFree vg 2 2 0 wz--n- <6,00g <2,01g For uses needing 'old' undecorated human unit simply will continue to use 'H|h' units. The new R|r may further change when we would recongnize some other way how to improve readability.
2017-01-09 18:30:49 +03:00
Support new R|r human readable units output format.
thin: refresh status when error processing fails When thin-pool processes event and 'lvextend --use-policies' fails rather capture up-to-date new info as the fullness percentage may have jumped noticable. This way we could use 'more' correct numbers when checking for thresholds.
2016-12-23 01:28:04 +03:00
Thin dmeventd plugin reacts faster on lvextend failure path with umount.
libdm: add dm_stats_bind_from_fd() dmsetup already has a version of this function, and dmfilemapd will need it too: move it to libdevmapper to avoid copying it around.
2016-12-18 17:40:57 +03:00
Add dm_stats_bind_from_fd() to bind a stats handle from a file descriptor.
libdm: drop callback on revert path The system is likely in some very inconsisten state. Do not try to make it even more problematic with trying to invoke tools like thin_check via callback.
2016-12-18 00:40:59 +03:00
Do not try call callback when reverting activation on error path.

====================================
cleanup: log_info to log_error Switch to more appropriate logging level.
2016-10-31 20:03:06 +03:00
Log failure of raid device with log_error level.
libdm: use dm_log_with_errno always Instead of compiling 2 log call for 2 different logging functions, and runtime decide which version to use - use only 'newer' function and when user sets his own OLD dm_log logging translate it runtime for old arg list set. The positive part is - we get shorter generated library, on the negative part this translation means, we always have evaluate all args and print the message into local on stack buffer, before we can pass this buffer to the users' logging function with proper expected parameters (and such function may later decide to discard logging based on message level so whole printing was unnecessary).
2016-11-03 19:15:07 +03:00
Use dm_log_with_errno and translate runtime to dm_log only when needed.
pre-release
2016-11-05 04:03:32 +03:00
Make log messages from dm and lvm library different from dmeventd.
dmeventd: debug only subsystemd with # sign Reword the logging logic and try to restore previous logging behavior for 'standalone' running daemon while preserving debuggable feautures it has gained. So actual rules: dmeventd without any '-d' option will syslog all messages from dmeventd.c it dmeventd plugins. log_notice()==log_verbose() log_info()==log_very_verbose() But to show also log_debug() used has to give '-ddd'. When user specified '-d, -dd, -ddd, -dddd' it will also enable tracing of messages from libdm & lib executed code - which is mainly useful for testing i.e.: 'dmeventd -fldddd'
2016-11-03 14:01:01 +03:00
Notice and Info messages are again logged from dmeventd and its plugins.
dmeventd: abort on internal error Provide same support for DM_ABORT_ON_INTERNAL_ERRORS we do have with default libdm logging as dmeventd is libdm based tool.
2016-11-02 16:40:12 +03:00
Dmeventd now also respects DM_ABORT_ON_INTERNAL_ERRORS as libdm based tool.
libdm: report logging with errno as changed default When user changes logging with 'dm_log_with_errno_init()' also report this as non default dm logging.
2016-11-03 14:07:27 +03:00
Report as non default dm logging also when logging with errno was changed.
logging: add more log macros Introduce macros: log_level(), log_stderr(), log_once(), log_bypass_report() For easier and more consisten way how to 'decoder' bits of info from passed 'level'. This patch fixes potential problem when 'level' of message might not have always masked right bits.
2016-11-02 16:39:13 +03:00
Use log_level() macro to consistently decode message log level in dmeventd.
dmsetup: Produce partial output if dev disappears. If a device disappears after obtaining the list of devices but before processing it as a member of that list, dmsetup exits with a failure code. Most commands still produce what output they can in these circumstances, but 'ls --tree' and 'info -c' with fields depending on device dependencies didn't. Change this.
2016-10-18 20:01:52 +03:00
Still produce output when dmsetup dependency tree building finds dev missing.
dmeventd: pthread_sigmask in single function Integrate back _unblock_sigalrm() and check for error code of pthread_sigmask() function so we do not use uninitialized sigmask_t on error path (Coverity).
2016-10-03 16:39:54 +03:00
Check and report pthread_sigmask() failure in dmeventd.
libdm: check for mem when _canonicalize_field_ids Add missing check for dm_pool_strdup() call (Coverity).
2016-10-03 17:29:55 +03:00
Check mem alloc fail in _canonicalize_field_ids().
raid: dmeventd plugin use 64bit arithmetic Coverity suggested to used 64bit unsigned ints instead of signed 32b int. Assuming there is no user of >31legs raid array.
2016-10-03 15:58:23 +03:00
Use unsigned math when checking more then 31 legs of raid.
libdm: fix dm_stats_delete_region() backwards compat The dm_stats_delete_region() call removes a region from the bound device, and, if the region is grouped, from the group leader group descriptor stored in aux_data. To do this requires a listed handle: previous versions of the library do not since no dependencies exist between regions without grouping. This leads to strange behaviour when a command built against an old version of the library is used with one supporting groups. Deleting a region with dmstats succeeds, but logs errors: # dmstats list Name RgID RgSta RgSiz #Areas ArSize ProgID vg_hex-root 0 0 1.00g 1 1.00g dmstats vg_hex-root 1 1.00g 1.00g 1 1.00g dmstats vg_hex-root 2 2.00g 1.00g 1 1.00g dmstats # dmstats delete --regionid 2 vg_hex/root Region ID 2 does not exist Could not delete statistics region. Command failed # dmstats list Name RgID RgSta RgSiz #Areas ArSize ProgID vg_hex-root 0 0 1.00g 1 1.00g dmstats vg_hex-root 1 1.00g 1.00g 1 1.00g dmstats This happens because the call to dm_stats_delete_region() is inside a dm_stats_walk_*() iterator: upon entry to the call, the iterator is at its end conditions and about to terminate. Due to the call to dm_stats_list() inside the function, it returns with an iterator at the beginning of a walk and performs a further iteration before exiting. This final loop makes a further attempt to delete the (already deleted) region, leading to the confusing error messages.
2016-09-27 19:46:52 +03:00
Fix 'dmstats delete' with dmsetup older than v1.02.129
libdm: fix stats walk compatibility with older dmsetup The current dmsetup.c handles DR_STATS and DR_STATS_META reports separately in _display_info_cols(), meaning that the stats walk functions are never called for these report types. Versions before v2.02.159 have a loop using dm_stats_walk_do() and dm_stats_walk_while(), that executes once for non-stats reports, and once per region, or area, for DR_STATS/DR_STATS_META reports. This older behaviour relies on the documented behaviour that the walk functions will accept a NULL pointer as the struct dm_stats* argument. This was broken by commit f1f2df7b: the NULL test on dms and dms->regions were incorrectly moved from the dm_stats_walk_end() wrapper to the internal '_stats_walk_end()' helper. Since the pointer is dereferenced in between these points, using an older dmsetup with current libdm results in a segfault when running a non-stats report: # dmsetup info -c vg00/lvol0 Segmentation fault (core dumped) Restore the NULL checks to the wrapper function as intended.

=================================
blkdeactivate: add -m|--mpathoption disablequeueing and use it for blk-availability systemd service and initscript blkdeactivate -m disablequeueing causes "multipathd disablequeueing maps" call inside blkdeactivate script before deactivating devices. This avoids a situation where blkdeactivate may wait for paths to appear if multipath is set to queueing and there's a stack of other devices and/or mount points on top of such multipath device. See also https://bugzilla.redhat.com/show_bug.cgi?id=1344381.
2016-07-12 10:52:18 +03:00
Disable queueing on mpath devs in blk-availability systemd service/initscript.
Add new -m|--mpathoption disablequeueing to blkdeactivate.

================================
doc: update dmstats.8.in for groups
2016-06-22 20:36:10 +03:00
Update default dmstats field selections for groups.
Add 'obj_type', 'group_id', and 'statsname' fields to dmstats reports.
Add --area, --region, and --group to dmstats to control object selection.
Add --alias, --groupid, --regions to dmstats for group creation and deletion.
Add 'group' and 'ungroup' commands to dmstats.
libdm: allow deleting regions with dm_stats_delete_group() Add a flag to dm_stats_delete_group() to allow optional deletion of all regions belonging to the group being removed.
2016-07-01 15:14:41 +03:00
Allow dm_stats_delete_group() to optionally delete all group members.
libdm: add stats group and region iterators and properties Add support do dm_stats_walk*() to walk over the set of available groups using the cursor embedded in the dm_stats handle, and to obtain the type of the object at the current stats cursor location. A set of flags is introduced to control which objects are visited: DM_STATS_WALK_AREA DM_STATS_WALK_REGION DM_STATS_WALK_GROUP DM_STATS_WALK_ALL A final flag suppresses visits to regions that contain only a single area - since the aggregate of such a region is idential to the area it contains this allows these duplicates to be filtered out: DM_STATS_WALK_SKIP_SINGLE_AREA If flags are not initialised before beginning a walk the default set matches the behaviour of previous versions of the library. Also accept group identifiers as immediate arguments to the counter, metric, and property functions by adding control flags to the region and area identifiers passed in. Region and area properties are mapped to their equivalents for the group (for example: group size is reported as the sum of all regions contained in the group). Counter and metric values are aggregated for the region or group.
2016-06-19 15:30:46 +03:00
Add dm_stats_get_object_type() to return the type of object present.
Add dm_stats_walk_init() allowing control of objects visited by walks.
libdm: add statistics groups Add a grouping facility to the libdm-stats library that allows the user to bind several regions together as a group. Groups may be used to aggregate data from several regions for reporting, or to select and sort among large sets of regions. A textual descriptor ("group tag") is associated with each group and is stored in the first group member's aux_data field. The tag contains the group member list and an optional alias for the group, allowing the user to assign meaningful names to groups of regions. These descriptors are parsed in @stats_list message responses and populate the resulting region and area tables with the group structure. Groups with overlapping regions are permitted but since this will result in some events being counted more than once a warning is printed in this case. Nested and overlapping groups are not currently supported and attempting to create these configurations results in error.
2016-02-29 20:52:29 +03:00
Add dm_stats_get_group_descriptor() to return the member list as a string.

2016-02-29 20:52:29 +03:00
Add dm_stats_{get,set}_alias() to set and retrieve alias names for groups.
Add dm_stats_get_group_id() to return the group ID for a given region.
Add dm_stats_{create,delete}_group() to allow grouping of stats regions.
libdm: add enum based counter and metric calls Add a new enum based interface for accessing counter and metric values that uses a single function for each: uint64_t dm_stats_get_counter(const struct dm_stats *dms, dm_stats_counter_t counter uint64_t region_id, uint64_t area_id); int dm_stats_get_metric(const struct dm_stats *dms, int metric, uint64_t region_id, uint64_t area_id, double *value); This simplifies the implementation of value aggregation for groups of regions. The named function interface now calls the enum interface internally so that all new functionality is available regardless of the method used to retrieve values.
2016-02-29 20:33:16 +03:00
Add enum-driven dm_stats_get_{metric,counter}() interfaces.
libdm: add dm_bitset_parse_list() Add a function to parse a list of integer values and ranges into a dm_bitset representation. Individual values signify that that bit is set in the resulting mask and ranges are given as a pair of start and end values, M-N, such that M and N are the first and last members of the range (inclusive). The implementation is based on the kernel's __bitmap_parselist() that is used for cpumasks and other set configuration passed in string form from user space.
2016-02-18 19:14:43 +03:00
Add dm_bitset_parse_list() to parse a string representation of a bitset.

2016-06-17 15:57:33 +03:00
=================================
libdm: select: recognize special selection string 'all' as an alias for blank selection string
2016-06-13 16:23:44 +03:00
Recognize 'all' keyword used in selection as synonym for "" (no selection).
libdm: report: add dm_report_set_selection Since we can do repeated dm_report_output calls now, we also like to be able to set selection for each of these outputs.
2016-05-12 16:04:37 +03:00
Add dm_report_set_selection to set selection for multiple output of report.
libdm: report: add DM_REPORT_OUTPUT_MULTIPLE_TIMES report flag to keep report data even after output is done The DM_REPORT_OUTPUT_MULTIPLE_TIMES instructs reporting code to keep rows even after dm_report_output call - the rows are not destroyed in this case which makes it possible to call dm_report_output multiple times.
2016-05-12 15:34:04 +03:00
Add DM_REPORT_OUTPUT_MULTIPLE_TIMES flag for multiple output of same report.
refactor: move field width calculation and sort preparation from _do_report_object to dm_report_output This also prepares code for repeated dm_report_output calls.
2016-05-12 15:07:05 +03:00
Move field width handling/sort init from dm_report_object to dm_report_output.
log: also pass log_print through report and add log_print_bypass_report for use in libdm-report for direct print without report log_print is used during cmd line processing to log the result of the operation (e.g. "Volume group vg successfully changed" and similar). We don't want output from log_print to be interleaved with current reports from group where log is reported as well. Also, the information printed by log_print belongs to the log report too, so it should be rerouted to log report if it's set. Since the code in libdm-report which is responsible for doing the report output uses log_print too, we need to use a different kind of log_print which bypasses any log report currently used for logging (...simply, we can't call log_print to output the log report itself which in turn would again reroute to report - the report would never get on output this way).
2016-05-19 13:19:48 +03:00
Add _LOG_BYPASS_REPORT flag for bypassing any log report currently set.
libdm: report: implement DM_REPORT_GROUP_JSON for JSON report output This patch introduces DM_REPORT_GROUP_JSON report group type. When using this group type and when pushing a report to such a group, these flags are automatically unset: DM_REPORT_OUTPUT_ALIGNED DM_REPORT_OUTPUT_HEADINGS DM_REPORT_OUTPUT_COLUMNS_AS_ROWS ...and this flag is set: DM_REPORT_OUTPUT_BUFFERED The whole group is encapsulated in { } for the outermost JSON object and then each report is reported on output as array of objects where each object is the row from report: { "report_name1": [ {field1="value", field2="value",...}, {field1="value", field2="value",...} ... ], "report_name2": [ {field1="value", field2="value",...}, {field1="value", field2="value",...} ... ] ... }
2016-05-02 15:21:40 +03:00
Introduce DM_REPORT_GROUP_JSON for report group with JSON output format.
libdm: report: implement DM_REPORT_GROUP_BASIC for extended report output This patch introduces DM_REPORT_GROUP_BASIC report group type. This type has exactly the classical output format as we know from before introduction of report groups. However, in addition to that, it allows to put several reports into a group - this is the very basic grouping scheme that doesn't change the output format itself: Report: report1_name Header1 Header2 ... value value ... value value ... ... ... ... Report: report2_name Header1 Header2 ... value value ... value value ... ... ... ...
2016-05-23 11:47:03 +03:00
Introduce DM_REPORT_GROUP_BASIC for report group with basic report output.
libdm: report: implement DM_REPORT_GROUP_SINGLE for a group containing single report only There's no change in output for this report group type - with this type, we only make sure there's always only one report in a group at a time, not more.
2016-06-16 12:23:56 +03:00
Introduce DM_REPORT_GROUP_SINGLE for report group having single report only.
libdm: report: introduce dm_report_group This patch introduces DM report group (represented by dm_report_group structure) that is used to group several reports to make a whole. As a whole, all the reports in the group follow the same settings and/or formatting used on output and it controls that the output is properly ordered (e.g. the output from different reports is not interleaved which would break readability and/or syntax of target output format used for the whole group). To support this feature, there are 4 new functions: - dm_report_group_create - dm_report_group_push - dm_report_group_pop - dm_report_group_destroy From the naming used (dm_report_group_push/pop), it's clear the reports are pushed onto a stack. The rule then is that only the report on top of the stack can be reported (that means calling dm_report_output). This way we make sure that the output is not interleaved and provides determinism and control over the output. Different formats may allow or disallow some of the existing report flags controlling output itself (DM_REPORT_OUTPUT_*) to be set or not so once the report is pushed to a group, the grouping code makes sure that all the reports have compatible flags set and then these flags are restored once each report is popped from the report group stack. We also allow to push/pop non-report item in which case such an item creates a structure (e.g. to put several reports together with any opening and/or closing lines needed on output which pose as extra formatting structure besides formatting the reports). The dm_report_group_push function accepts an argument to pass any format-specific data needed (e.g. handle, name, structures passed along while working with reports...). We can call dm_report_output directly anytime we need (with the only restriction that we can call dm_report_output only for the report that is currently on top of the group's stack). Or we don't need to call dm_report_output explicitly in which case all the reports in a stack are reported on output automatically once we call dm_report_group_destroy.
2016-05-02 15:21:05 +03:00
Add dm_report_group_{create,push,pop,destroy} to support report grouping.

So the 'TODO' part now finally know the answer - there is 'sparc64' architecture which imposes limitation to read 64b words only through 64b aligned address. Since we never could know how is the user going to use the returned pointer and the userusually expects it's aligned on the highest CPU required alignement, preserve it also for char*.

2015-11-16 02:00:32 +03:00
Add missing check for allocation inside dm_split_lvm_name().
libdm: add test for dm_task_get_message_response() Coverity notices dm_task_get_message_response() result should be checked for NULL which should not be passed to dm_pool_strdup().
2015-11-09 11:50:46 +03:00
Test dm_task_get_message_response for !NULL in dm_stats_print_region().
dmsetup: add missing checks for dm_stats_create() ret value Coverity likes to see a check for dms not being NULL, so add those missing ones...
2015-11-09 11:45:53 +03:00
Add checks for failing dm_stats_create() in dmsetup.
libdevmapper-event: fix fifo leak on error path Coverity: when _init_client() fails, client fifo could have been already openned and needs to be closed on error path.
2015-11-08 19:10:38 +03:00
Add missing fifo close when failed to initialize client connection.

Version 1.02.110 - 30th October 2015
====================================
thin: dmeventd plugin check number of failures If plugin's lvm command execution fails too often (>10 times), there is no point to torture system more then necessary, just log and drop monitoring in this case.
2015-10-29 13:52:11 +03:00
Disable thin monitoring plugin when it fails too often (>10 times).
dmeventd: event string parser handles empty field Improve event string parser to avoid unneeded alloc+free. Daemon talk function uses '-' to mark NULL/missing field. So restore the NULL pointer back on parser. This should have made old tools like 'dmevent_tool' work again. As now 'uuid' or 'dso' could become NULL and then be properly used in _want_registered_device() function. Since lvm2 always fill these parameters, this change should have no effect on lvm2.
2015-10-27 13:12:59 +03:00
Fix/restore parsing of empty field '-' when processing dmeventd event.
libdm: dm_tree_node_size_changed recognizes reduction Add more functionality to size_changed function. While 'existing' API only detected 0 for unchanged, and !0 for changed, new improved API will also detected if the size has only went bigger - or there was size reduction. Function work for the whole dm-tree - so no change is size is always 0. only size extension 1. and if some size reduction is there - returns -1. This result can be used for better evaluation whether we need to flush before suspend.
2015-10-25 21:27:09 +03:00
Enhance dm_tree_node_size_changed() to recognize size reduction.
dmeventd: exit on idle Implementing exit when 'dmeventd' is idle. Default idle timeout set to 1 hour - after this time period dmeventd will cleanly exit. On systems with 'systemd' - service is automatically started with next contact on dmeventd communication socket/fifo. On other systems - new dmeventd starts again when lvm2 command detects its missing and monitoring is needed.
2015-10-22 21:36:46 +03:00
Support exit on idle for dmenventd (1 hour).
dmeventd: handle signal from plugin Add support to unmonitor device when monitor recognizes there is nothing to monitor anymore. TODO: possibly API change with return value could be also used.
2015-10-22 16:48:14 +03:00
Add support to allow unmonitor device from plugin itself.
New design for thread co-operation in dmeventd.
dmeventd: code mode _get_device_status Move _get_device_status() in code. Use dm_task_no_flush() function when reading status. (e.g. none blocking for thins pool)
2015-10-22 13:36:25 +03:00
Dmeventd read device status with 'noflush'.
dmeventd: use dm_hold_control_dev Need here to keep control device opened while there is 'any' dso plugin loaded - otherwise there would a race closing controlfd inside lvm2 plugin while some other monitoring thread would tried to execute another WAITEVENT task.
2015-10-21 21:52:29 +03:00
Dmeventd closes control device when no device is monitored.
dmeventd: thin plugin update Use dm_make_percent for percentage calculation like lvm2 command. Use a single call for resize.
2015-10-20 15:19:35 +03:00
Thin plugin for dmeventd improved percentage usage.
dmeventd: snapshot plugin updates Improve test for invalid snapshot. Use dm_make_percent() to manipulate with exactly same percentage as lvm2 command is using.
2015-10-22 16:35:55 +03:00
Snapshot plugin for dmeventd improved percentage usage.
libdm: add dm_hold_control_dev Support hold of control device open. Useful for daemons so the control device is not frequently reopenned.
2015-10-21 21:36:15 +03:00
Add dm_hold_control_dev to allow holding of control device open.
libdm: add dm_report_compact_given_fields dm_report_compact_given_fields is the same as dm_report_compact_fields, but it processes only given fields, not all the fields in the report like dm_report_compact_field does.
2015-10-16 16:50:13 +03:00
Add dm_report_compact_given_fields to remove given empty fields from report.
dmeventd: rework raid plugin Switch to per-thread mem-pool and lock only for lvm2 calls. Use libdm parser for raid status line.
2015-10-13 12:37:14 +03:00
Use libdm status parsing and local mem raid dmeventd plugin.
dmeventd: less locking mirror Rework mirror plugin to use per-thread mem-pool. This allows to use locking only for lvm2 library calls.
2015-10-13 12:35:44 +03:00
Use local mem pool and lock only lvm2 execution for mirror dmeventd plugin.
dmeventd: less locking for snapshot and thin Use lvm lock for lvm library calls. dm functions in-use are 'thread-safe' since we use local per-thread mem pool.
2015-10-13 12:35:03 +03:00
Lock protect only lvm2 execution for snapshot and thin dmeventd plugin.
dmeventd: add local mempool for raid and mirror Using local mempools allows to drop locks when such memory is needed.
2015-10-13 12:28:57 +03:00
Use local mempool for raid and mirror plugins.
dmeventd: new initialization of plugin threads Rework thread creation code to better use resources. New code will not leak 'timeout' registered thread on error path. Also if the thread already exist - avoid creation of thread object and it's later destruction. If the race is noticed during adding new monitoring thread, such thread is put on cleanup list and -EEXIST is reported.
2015-10-13 10:43:09 +03:00
Reworked thread initialization for dmeventd plugins.
dmeventd: handle snapshot overflow When snapshot reports overflow, handle it in the same way as Invalid. Until better ideas are implemented.
2015-10-09 22:41:50 +03:00
Dmeventd handles snapshot overflow for now equally as invalid.
dmeventd: syslog -> log_xxxxx Convert logging of dmeventd to libdm logging macros.
2015-10-09 22:57:48 +03:00
Convert dmeventd to use common logging macro system from libdm.
dmeventd: correct ret code for fail As _do_register_device() calls register_device() function that returns 1 success & 0 fail - ret = -ENOMEM for fail case instead of 0.
2015-10-13 10:49:59 +03:00
Return -ENOMEM when device registration fails instead of 0 (=success).
libdm: enforce writethrough mode for cleaner With "cleaner" policy always use 'writethrough' mode.
2015-10-13 15:06:15 +03:00
Enforce writethrough mode for cleaner policy.
blkdeactivate: recognize and deactivate MD devices too
2015-10-06 14:25:37 +03:00
Add support for recognition and deactivation of MD devices to blkdeactivate.
libdm: Move status fns from deptree to targets. libdm-deptree is only for functions working with dm tree nodes.
2015-09-28 22:28:31 +03:00
Move target status functions out of libdm-deptree.
raid: Fix raid target write_behind parameter. Now uses correct "max_write_behind" instead of "writebehind". (Includes some tidying up.)
2015-09-23 17:53:27 +03:00
Correct use of max_write_behind parameter when generating raid target line.
systemd: use {local,remote}-fs-pre.target instead of {local,remote}-fs.target We want most of our units to be started before any local/remote mount points are mounted - we used {local,remote}-fs.target for this purpose before, but it was not 100% correct as there's even {local,remote}-fs-pre.target special systemd unit reserved for this exact purpose. See also man 7 systemd.special and "local-fs-pre.target"/"remote-fs-pre.target" description.
2015-09-23 14:17:12 +03:00
Fix dm-event systemd service to make sure it is executed before mounting.

dmsetup: use noflush with force removal When user specifies '--force' with remove/remove_all/wipe_table use '--noflush --nolockfs' resume flags, so the operation will not block when device underneath is blocked.
2015-09-18 15:35:52 +03:00
Use --noflush and --nolockfs when removing device with --force.
libdm: parse Overflow string from snapshot status This is likely to be a new 'info' provided by kernel snapshot target. For now just parse this string.
2015-09-18 15:41:00 +03:00
Parse new Overflow status string for snapshot target.

2015-09-17 15:36:39 +03:00
Check dir path components are valid if using dm_create_dir, error out if not.
libdm: dev_node: use lstat instead of stat while removing and renaming nodes When using udev, the /dev/mapper entries are symlinks - fix the code to count with this. This patch also fixes the dmsetup mknodes and vgmknodes to properly repair /dev/mapper content if it sees dangling symlink in /dev/mapper.
2015-09-17 14:31:34 +03:00
Fix /dev/mapper handling to remove dangling entries if symlinks are found.
libdm: report: make it possible to use blank value as selection for string list report field $ lvs -o name,tags vg LV LV Tags lvol0 lvol1 mytag Before this patch: $ lvs -o name,tags vg -S 'tags=""' Failed to parse string list value for selection field lv_tags. Selection syntax error at 'tags=""'. Use 'help' for selection to get more help. (and the same for -S 'tags={}' and -S 'tags=[]') With this patch applied: $ lvs -o name,tags vg -S 'tags=""' LV LV Tags lvol0 (and the same for -S 'tags={}' and -S 'tags=[]')
2015-09-17 11:19:15 +03:00

Parse thin-pool status with one single routine internally.
WHATS_NEW_DM: fix histogram entries for 1.02.107 The histogram entries were under the wrong version (1.02.106). Fix that and describe the library changes in more detail.
2015-09-04 21:53:10 +03:00
Add --histogram to select default histogram fields for list and report.

Add dm_histogram_to_string() to format histogram data in string form.
Add public methods to libdm to access numerical histogram config and data.
Parse and store histogram data in dm_stats_list() and dm_stats_populate().
Add an argument to specify histogram bounds to dm_stats_create_region().
Add dm_histogram_bounds_from_{string,uint64_t}() to parse histogram bounds.
Add dm_histogram handle type to represent a latency histogram and its bounds.
libdm: pkgconfig: fix devmapper.pc to not reference nonexistent rt.pc file librt doesn't have a pkgconfig file so use Libs.private: -lrt instead to declare the dependency directly. The same applies for -lm which is also used and which hasn't been defined in the devmapper.pc file yet.
2015-09-03 10:28:42 +03:00
Fix devmapper.pc pkgconfig file to not reference non-existent rt.pc file.
libdm: Reinstate dm_task_get_info@Base. Move the version script local:* wildcard into a node of its own to avoid conflicting with in-source export macro definitions.

2015-08-10 03:02:31 +03:00
===================================
WHATS_NEW: Update.
2015-08-16 03:16:16 +03:00
Fix 'dmstats list -o all' segfault.
Separate dmstats statistics fields from region information fields.
Add interval and interval_ns fields to dmstats reports.
WHATS_NEW_DM: recent commits (stats field split and timestamp headers)
2015-08-14 15:20:20 +03:00
Do not include internal glibc headers in libdm-timestamp.c (1.02.104)
dmsetup: Restructure arg handling. Introduce enums and global variables to record cleanly which command we are processing and eliminate the historically inconsistent use of the shifted argv[0] and fix assorted bugs discovered along the way. Add dm_report_is_empty() to indicate there is no data awaiting output and use this to suppress dmsetup report headings when no data is output so we don't get a stray line saying 'Help' at the end of reporting help. Define a report type (as the interface requires) so -o all selects the right fields in splitname. (A fix for stats list will follow.) Exit immediately if no device is supplied to dmsetup wipe_table instead of hitting errors later and failing. Adjust the command name printed in usage/help output to match command invoked (most of the time).
2015-08-14 00:30:39 +03:00
Exit immediately if no device is supplied to dmsetup wipe_table.
Suppress dmsetup report headings when no data is output. (1.02.104)
Adjust dmsetup usage/help output selection to match command invoked.
Fix dmsetup -o all to select correct fields in splitname report.
Restructure internal dmsetup argument handling across all commands.
Add dm_report_is_empty() to indicate there is no data awaiting output.
libdm: cache target arg validation Add some arg validation for dm_tree_node_add_cache_target().
2015-08-11 14:31:26 +03:00
Add more arg validation for dm_tree_node_add_cache_target().
dmstats: replace --force with new stats-specific --alldevices The '--force' switch is only used by dmstats to allow either creation or deletion of one or more regions on all devices. These operations do not carry any risk: just a possible mess of region IDs to be cleaned up. Remove the use of '--force' for stats commands and change current uses to a new '--alldevices' switch.
2015-08-13 16:42:55 +03:00
Add --alldevices switch to replace use of --force for stats create / delete.

2015-08-05 10:28:35 +03:00
Report timestamps of ioctls with dmsetup -vvv.
report: recognize report field name variants without any underscores too Whenver reporting field name is registered with libdevmapper and if the field name contains any number of underscores ('_'), libdm can now automatically recognize any of its variant without any underscores used. For example: ..for underscores in prefixes: pvs -o pv_name pvs -o name pvs -o pvname (newly recognized besides pvname) ..for underscores in the name: lvs -o cache_mode lvs -o cachemode ..or even multiple underscores: pvs -o pv___na___me It's all variant of the same field name.
2015-08-03 17:29:50 +03:00
Recognize report field name variants without any underscores too.
dmsetup: Add --count and --interval to reports. For example, to monitor active devices every second you can now run dmsetup info -c --count 0.

Version 1.02.101 - 3rd July 2015
================================
libdm: support for posting messages in suspend Add support for sending message in suspend tree for thin-pools. When this operation is requested whole subtree suspend is then skipped. This is experimantal support for new lvm2 code for sending message in suspend phase where 'thin-pool origin-only suspend' will send messages instead of really suspending thin-pool tree. When suspening thin volume origin-only - only thin volume is suspended, then messages are posted and thin-pool suspend is skipped.
2015-07-01 14:30:14 +03:00
Add experimental support to passing messages in suspend tree.
report: add infrastructure to recognize fuzzy reserved names and returning dynamic reserved values With fuzzy names we mean the names for which it's hard or even impossible to enumerate all possible variations of the name - the name needs to be evaluated. An example of fuzzy name is a name which has a base (substring) which matches and it can contain arbitrary variations around this base. We can cover human language better with fuzzy names as people may use several different names (or sentences) to denote the same thing. With dynamic values we mean the values which are not constants and they need to be evaluated in runtime. An example of dynamic value is a value which depends on current system state (e.g. time, current configuration or any other state which may change and it needs runtime evaluation). There's a handler that can be registered with reporting/selection using dm_report_reserved_handler instance. This is a central point in which the computation/evaluation happens when processing reserved values. Currently, there are two actions declared: DM_REPORT_RESERVED_PARSE_FUZZY_NAME (translates fuzzy name into canonical name) DM_REPORT_RESERVED_GET_DYNAMIC_VALUE (gets value for canonical name) The handler is then registered as value in struct dm_report_reserved_value (see explaining comments besided the struct dm_report_reserved_value in libdevmapper.h). Also, this patch provides support for simple caching of values used during report/selection via dm_report_value_cache_{set,get}. This is supposed to be used mainly in the dm_report_reserved_handler instances to save values among calls so all the handler calls work with the same base value used in computation/evaluation and/or possibly to save resources if the evaluation is more time-consuming. The cache is attached to the dm_report handle and so the cache is dropped one dm_report is dropped.

Add dm_report_value_cache_{set,get} to support caching during report/select.

Version 1.02.100 - 30th June 2015
=================================
report: add support for time (basic) This patch adds support for time values used in reporting fields. The raw values are always stored as number of seconds since epoch. The support that comes with this patch is the basic one which allows only for recognition of strictly formatted date and time in selection criteria (the format follows a subset of formats defined by ISO 8601): date time timezone date: YYYY-MM-DD (or shortly YYYYMMDD) YYYY-MM (shortly YYYYMM), auto DD=1 YYYY, auto MM=01 and DD=01 time: hh:mm:ss (or shortly hhmmss) hh:mm (or shortly hhmm), auto ss=0 hh (or shortly hh), auto mm=0, auto ss=0 timezone (always with + or - sign): +hh:mm or -hh:mm (or shortly +hhmm or -hhmm) +hh or -hh Or directly the time (number of seconds) since Epoch (1970-01-01 00:00:00 UTC) when the number value is prefixed by "@": @number_of_seconds_since_epoch This patch also adds aliases for comparison operators used together with time values which are more intuitive to use: since (as alias for >=) after (as alias for >) until (as alias for <=) before (as alias for <) For example: $ lvmconfig --type full report/time_format time_format="%Y-%m-%d %T %z %Z [%s]" $ lvs -o name,time vg LV Time lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541] lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543] lvol2 2015-04-26 14:52:20 +0200 CEST [1430052740] lvol3 2015-06-30 14:52:23 +0200 CEST [1435668743] $ lvs vg -o name,time -S 'time since "2015-04-26 15:00" && time until "2015-06-30"' LV Time lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541] lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543] lvol3 2015-06-30 14:52:23 +0200 CEST [1435668743] $ lvs vg -o name,time -S 'time since "2015-04-26 15:00" && time until "2015-06-30 6:00"' LV Time lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541] lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543] $ lvs vg -o name,time -S 'time since @1435519541' LV Time lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541] lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543] lvol3 2015-06-30 14:52:23 +0200 CEST [1435668743] This is basic time recognition support that is directly a part of libdevmapper. Recognition of more free-form expressions will be a part of subsequent patches.
2015-05-21 16:19:03 +03:00
Add since, after, until and before time operators to be used in selection.
Add support for time in reports and selection: DM_REPORT_FIELD_TYPE_TIME.
select: add support for range reserved values and flagging named-only values This patch allows for registration and recognition of reserved values which are ranges, so they're composed of two values actually to denote the lower and upper bound for the range (stored as an array with exactly two items to define the boundaries). Also, this patch allows for flagging reserved values as named-only which means that such values are not strictly reserved. The strictly reserved values are reserved values as used before this patch. Distinction between strictly-reserved and named-only values is clearly visible with comparisons. Normally, strictly reserved value is not accounted for if we do "greater than" or "lower than" comparisons, for example: 1 2 3 .... | abc - we have "abc" as reserved value for field with value "2" - the value reported for the field is "abc" (or "2", it doesn't matter here) - the selection we're processing is -S 'field < abc' - the result of the selection gives nothing as "abc" is strictly reserved value (bound to "2") and there's no order defined for it and it would only match if we directly compared the value (so -S 'field = abc' would match) With named-only values, the "abc" is named-only value for "2", so selection -S 'field < abc" is the same as using -S 'field < 2'. The "abc" is just an alias for some value so the value or its assigned name can be used equally in selection criteria.
2015-06-30 11:13:35 +03:00
Support report reserved value ranges: DM_REPORT_FIELD_RESERVED_VALUE_RANGE.
Support report reserved value names: DM_REPORT_FIELD_RESERVED_VALUE_NAMED.

Version 1.02.97 - 15th May 2015
===============================
libdm: new dm_task_get_info with internal_suspend Introduce new implmentation of dm_task_get_info() function with support for reading internal_suspend. . This time it is done in a 'versioned' way. We keep the old fashion dm_task_get_info(Base) to implement the old behavior of 1.02.95 libdm code. libdm version 1.02.96 introduced 'macro' wrapper dm_task_get_info_with_deferred_remove with new implementation of dm_task_get_info() - we cannot do anything else then to provide compatible version of this symbol. Now in version 1.02.97 we add new versioned implementation of dm_task_get_info(DM_1_02_97) symbol. This has the effect that i.e. rpm build will finaly resolve proper dependency on a new symbol - so it will be no longer possible, to build a new binary and use old library (rpm -q --provides will show libdevmapper.so.1.02(DM_1_02_97)(64bit)) Also the history is now tracked. If a new function is added (or reimplemented), it needs to be placed in proper file, so it could be exported with right versioning symbol. File .exported_symbols.Base should and any existing older DM should be treated as read-only after a release. Also - only libdm has been currently enhanced with versioned .Base file, as soon as other libs (liblvm, libdevmapper-event) needs changes they should also get their exported symbol files - meanwhile make.tmpl handles both cases.
2015-05-15 16:29:46 +03:00
New dm_task_get_info(DM_1_02_97) supports internal_suspend state.
New symbols are versioned and comes with versioned symbol name (DM_1_02_97).

==============================
select: fix matching reserved values while <,<=,>,>= is used in selection criteria Scenario: $ vgs -o+vg_mda_copies VG #PV #LV #SN Attr VSize VFree #VMdaCps fedora 1 2 0 wz--n- 9.51g 0 unmanaged vg 16 9 0 wz--n- 1.94g 1.83g 2 $ lvs -o+read_ahead vg/lvol6 vg/lvol7 LV VG Attr LSize Pool Origin Data% Rahead lvol6 vg Vwi-a-tz-- 1.00g pool lvol5 0.00 auto lvol7 vg Vwi---tz-k 1.00g pool lvol6 256.00k Before this patch: $vgs -o vg_name,vg_mda_copies -S 'vg_mda_copies < unmanaged' VG #VMdaCps vg 2 Problem: Reserved values can be only used with exact match = or !=, not <,<=,>,>=. In the example above, the "unamanaged" is internally represented as 18446744073709551615, but this should be ignored while not comparing field directly with "unmanaged" reserved name with = or !=. Users should not be aware of this internal mapping of the reserved value name to its internal value and hence it doesn't make sense for such reserved value to take place in results of <,<=,> and >=. There's no order defined for reserved values!!! It's a special *reserved* value that is taken out of the usual value range of that type. This is very similar to what we have already fixed with 2f7f6932dcd450ba75fe590aba8c09838d2618dc, but it's the other way round now - we're using reserved value name in selection criteria now (in the patch 2f7f693, we had concrete value and we compared it with the reserved value). So this patch completes patch 2f7f693. This patch also fixes this problem: $ lvs -o+read_ahead vg/lvol6 vg/lvol7 -S 'read_ahead > 32k' LV VG Attr LSize Pool Origin Data% Rahead lvol6 vg Vwi-a-tz-- 1.00g pool lvol5 0.00 auto lvol7 vg Vwi---tz-k 1.00g pool lvol6 256.00k Problem: In the example above, the internal reserved value "auto" is in the range of selection "> 32k" - it shouldn't match as well. Here the "auto" is internally represented as MAX_DBL and of course, numerically, MAX_DBL > 256k. But for users, the reserved value should be uncomparable to any number so the mapping of the reserved value name to its interna value is transparent to users. Again, there's no order defined for reserved values and hence it should never match if using <,<=,>,>= operators. This is actually exactly the same problem as already described in 2f7f6932dcd450ba75fe590aba8c09838d2618dc, but that patch failed for size field types because of incorrect internal representation used. With this patch applied, both problematic scenarios mentioned above are fixed now: $ vgs -o vg_name,vg_mda_copies -S 'vg_mda_copies < unmanaged' (blank) $ lvs -o+read_ahead vg/lvol6 vg/lvol7 -S 'read_ahead > 32k' LV VG Attr LSize Pool Origin Rahead lvol7 vg Vwi---tz-k 1.00g pool lvol6 256.00k

libdm: report: add dm_report_object_is_selected The new dm_report_object_is_selected fn makes it possible to opt whether the object reported should be displayed on output or not. Also, in addition to that, it makes it possible to save the result of selection (either 0 or 1). So dm_report_object_is_selected is simply more general form of object reporting fn - combinations now allow for: dm_report_object_is_selected(rh, object, 1, NULL): This is exactly the original dm_report_object fn and it's fully equal to it. dm_report_object_is_selected(rh, object, 0, selected): Do not display the result on output, but save info whether the object is selected or not in 'selected' variable. dm_report_object_is_selected(rh, object, 1, selected): Display the result on output (if it passes selection criteria) and save whether the object is selected or not in 'selected' variable. dm_report_object(rh, object, 0, NULL): This combination is not allowed - it will end up with internal error. We're either interested in selection status or we want to display the result on output or both, but never nothing of the two.

report: selection: fix selection criteria to not match reserved values when using >, <, >=, < Some values are reserved for special purpose like 'undefined', 'unmanaged' etc. When using >, <, >= and < comparison operators where the range is considered, do not include reserved values as proper values in this range which would otherwise result in not so obvious criteria match (as the reserved value is actually transparent for the user). It's incorrect. Example scenario: $ vgs -o vg_name,vg_mda_copies vg1 vg2 VG #VMdaCps vg1 1 vg2 unmanaged The "unmanaged" is actually mapped onto reserved value 18446744073709551615 (2^64 - 1) internally. Such reseved value is already caught on selection criteria input properly: $ vgs -o name,vg_mda_copies vg1 vg2 -S 'vg_mda_copies=18446744073709551615' Numeric value 18446744073709551615 found in selection is reserved. However, we still need to fix situaton where the reserved value may be included in resulting range: Before this patch: $ vgs -o vg_name,vg_mda_copies vg1 vg2 -S 'vg_mda_copies >= 1' VG #VMdaCps vg1 1 vg2 unmanaged With this patch applied: $ vgs -o vg_name,vg_mda_copies vg1 vg2 -S 'vg_mda_copies >= 1' VG #VMdaCps vg1 1 From the examples above, we can see that without this patch applied, the vg_mda_copies >= 1 also matched the reserved value 18446744073709551615 (which is represented by the "unamanged" string on report). When applying the operators, such values must be skipped! They're meant to be matched only against their string representation only, e.g.: $ vgs -o name,vg_mda_copies vg1 vg2 -S 'vg_mda_copies=unmanaged' VG #VMdaCps vg2 unmanaged ...or any synonyms: $ vgs -o name,vg_mda_copies vg1 vg2 -S 'vg_mda_copies=undefined' VG #VMdaCps vg2 unmanaged

If dm module is not loaded during dm_is_dm_major call, there are no lines for dm in /proc/devices, of course. Normally, dm_is_dm_major is called to check existing devices, hence if module is not loaded, we can expect there's no DM device present at the same time so we can directly return 0 here (meaning the major number being inspected is not dm device's one). See also https://bugzilla.redhat.com/show_bug.cgi?id=1059711.

dmsetup: Support remove --deferred. This patch adds a new flag --deferred to dmsetup remove. If this flag is specified and the device is open, it is scheduled to be deleted on close. struct dm_info is extended. The existing dm_task_get_info() is converted into a wrapper around the new version dm_task_get_info_with_deferred_remove() so existing binaries can still use the old smaller structure. Recompiled code will pick up the new larger structure. From: Mikulas Patocka <mpatocka@redhat.com>

select: add support for selection to match string list subset, recognize { } operator Using "[ ]" operator together with "&&" (or ",") inside causes the string list to be matched if and only if all the items given match the value reported and the number of items also match. This is strict list matching and the original behaviour we already have. In contrast to that, the new "{ }" operator together with "&&" inside causes the string list to be matched if and only if all the items given match the value reported but the number of items don't need to match. So we can provide a subset in selection criteria and if the subset is found, it matches. For example: $ lvs -o name,tags LV LV Tags lvol0 a lvol1 a,b lvol2 b,c,x lvol3 a,b,y $ lvs -o name,tags -S 'tags=[a,b]' LV LV Tags lvol1 a,b $ lvs -o name,tags -S 'tags={a,b}' LV LV Tags lvol1 a,b lvol3 a,b,y So in the example above the a,b is subset of a,b,y and therefore it also matches. Clearly, when using "||" (or "#") inside, the { } and [ ] is the same: $ lvs -o name,tags -S 'tags=[a#b]' LV LV Tags lvol0 a lvol1 a,b lvol2 b,c,x lvol3 a,b,y $ lvs -o name,tags -S 'tags={a#b}' LV LV Tags lvol0 a lvol1 a,b lvol2 b,c,x lvol3 a,b,y Also in addition to the above feature, fix list with single value matching when using [ ]: Before this patch: $ lvs -o name,tags -S 'tags=[a]' LV LV Tags lvol0 a lvol1 a,b lvol3 a,b,y With this patch applied: $ lvs -o name,tags -S 'tags=[a]' LV LV Tags lvol0 a In case neither [] or {} is used, assume {} (the behaviour is not changed here): $ lvs -o name,tags -S 'tags=a' LV LV Tags lvol0 a lvol1 a,b lvol3 a,b,y So in new terms 'tags=a' is equal to 'tags={a}'.
2014-08-13 17:39:03 +04:00
Add support for selection to match string list subset, recognize { } operator.
Fix string list selection with '[value]' to not match list that's superset.
select: fix string list selection to match whole words only but not prefixes of searched string $ lvs -o name,tags vg/lvol0 LV LV Tags lvol0 a Before this patch: $ lvs -o name,tags vg/lvol0 -S 'tags=[a]' LV LV Tags lvol0 a $ lvs -o name,tags vg/lvol0 -S 'tags=[ab]' LV LV Tags lvol0 a (incorrect!) $ lvs -o name,tags vg/lvol0 -S 'tags=[abc]' LV LV Tags lvol0 a (incorrect!) With this patch applied: $ lvs -o name,tags vg/lvol0 -S 'tags=[a]' LV LV Tags lvol0 a $ lvs -o name,tags vg/lvol0 -S 'tags=[ab]' (no result - correct!) $ lvs -o name,tags vg/lvol0 -S 'tags=[abc]' (no result - correct!)
2014-08-13 17:27:00 +04:00
Fix string list selection to match whole words only, not prefixes.

Version 1.02.88 - 5th August 2014
=================================
activation: Fix upgrades using uuid suffixes. 2.02.106 added suffixes to some LV uuids in the kernel. If any of these LVs is activated with 2.02.105 or earlier, and then a later version is used, the LVs appear invisible and activation commands fail. The code now has to check the kernel for both old and new uuids.
2014-07-31 00:55:11 +04:00
Add dm_tree_set_optional_uuid_suffixes to handle upgrades.

2014-06-23 17:03:32 +04:00
================================
report: make "help" and "?" field implicit Making "help" and "?" implicit also simplifies code since the dm_report_init caller (lvm/dmsetup) doesn't need to check on dm_report_init return whether "help" or "?" was hit while parsing fields/sort keys in libdevmapper. The libdevmapper now sets internal "RH_ALREADY_REPORTED" flag after it reports the "help" or "?" implicit field. Then libdevmapper itself checks for this flag in dm_report_object and if found, the actual reporting is skipped (because the "help" implicit field was reported instead of the actual report).
2014-06-19 17:33:16 +04:00
Make "help" and "?" reporting fields implicit.
WHATS_NEW: commits 7dbbc05a69c4cb9756464720cad29e3c1ed971c3..b16f5633ab199dedfd25f08562f686a6fb4aba9d Report selection support...
2014-06-18 12:48:53 +04:00
Recognize implicit "selected" field if using dm_report_init_with_selection.

Add dm_percent_range_t,dm_percent_to_float,dm_make_percent to libdm for reuse.
Add dm_report_reserved_value to libdevmapper for reserved value definition.
Also display field types when listing all fields in selection help.
Recognize "help" keyword in selection string to show brief help for selection.
WHATS_NEW: commit 76467bdcfd297ffbe2c088b6340ecc7d17d56742 Ordering string list items on reports is also new compared to previous state where items were not ordered at all and they got reported simply as they appeared/were processed.
2014-06-18 14:30:34 +04:00
Always order items reported as string list field lexicographically.
WHATS_NEW: commits 7dbbc05a69c4cb9756464720cad29e3c1ed971c3..b16f5633ab199dedfd25f08562f686a6fb4aba9d Report selection support...

dmsetup: add warning Warn when --udevcookie/DM_UDEV_COOKIE is used with 'dmsetup remove --force'. When command is doing multiple ioctl operations on a single device, it may invoke udev activity, that is colliding with further ioctl commands. The result of such operation becomes unpredictable. Use of --retry could partially help...
2014-05-27 00:51:04 +04:00
Warn user about incorrect use of cookie with 'dmsetup remove --force'.
report: export DM_REPORT_FIELD_RESERVED_NAME_{HELP,HELP_ALT} and show help on '<lvm_command> -O help' Share DM_REPORT_FIELD_RESERVED_NAME_{HELP,HELP_ALT} between libdm and any libdm user to handle reserved field names, in this case the virtual field name to show help instead of failing on unrecognized field. The libdm user also needs to check the field name so it can fire proper code in this case (cleanup, exit etc.).
2014-05-15 12:58:05 +04:00
Also recognize 'help'/'?' as reserved sort key name to show help.
libdevmapper: add dm_units_to_factor for size unit parsing Actually moving the existing code from LVM to libdm for reuse.

Version 1.02.85 - 10th April 2014
=================================
libdm: check for _build_dev_path failure Enhance internal function _build_dev_path for failure if buffer would be too small. Use memcpy instead printf for a single string.
2014-04-04 23:47:54 +04:00
Check for sprintf error when building internal device path.
libdm: check for size when opening control node Use dm_snprintf() to detect fail if open_control node would not have fit into buffer.
2014-04-04 23:46:45 +04:00
Check for sprintf error when creating path for dm control node.
libdm: fail if buffer for version is to short Return fail error code, if supplied buffer is too small.
2014-04-04 23:43:57 +04:00
When buffer for dm_get_library_version() is too small, return error code.
libdm: always dm_lib_init mangling mode If there ever would be a second call to dm_lib_init() and envvar would be improperly set, some last set value would be used while it should reset to default mangling mode.
2014-04-04 23:24:41 +04:00
Always reinitialize _name_mangling_mode in dm_lib_init().
libdm: track implicit dependecies When the node enters dtree with implicit dependency, it automatically has udev flags from parent node and could not be changed later when the node has been entered again via i.e lvm's preload tracking. Resolve this by tracking whether the node has been created by implicit dependency tracking or has been entered explicitely. Implicit node could be later upgraded by an explicit _add_dev() with proper udev_flags. For implicit devices add special udev flags to avoid any scan and udev rule processing if we resume such device. Patch allows easier removing of orphan nodes.
2014-04-07 22:21:20 +04:00
Add tracking flag about implicitly added devices into dm_tree.
dmeventd: wakeup timeout thread earlier When the last entry in the timeout queue is unregistered, wakeup sleeping condition, so the thread is deleted earlier. So the thread resource is release earlier. Also when monitored with tools like valgrind this eliminites reported leak.
2014-03-10 12:40:32 +04:00
Stop timeout thread immediately when the last worker thread is finished.
dmeventd: remember number of log disablings Individual events are handled through separate threads, so once we have more then a single thread in this eventwait sleeping, we got race on the dm_log setting, since if one event is timeout out on alarm, while another is still waiting, then dm log has been restored to NULL and the next sigalarm has been reported as error. Fix it by introducing counter which is protected via mutex, and only when the last event is released, logging is restored. TODO: libdm seems to have some static vars which may audit for this type of use.
2014-03-10 12:47:44 +04:00
Fix dmeventd logging with parallel wait event processing.
libdm: enhance thin transaction_id validation Reuse _node_send_messages for just checking for valid transaction_id with preload. This allows earlier detection of incosistent thin pool. Code does the same thing, except for sending messages.
2014-02-24 12:43:14 +04:00
Reuse _node_send_messages() for validation of transaction_id in preload.
libdm: hardening transaction_id validation Improve testing of transation_id to not allow other difference then either kernel TID is equal or is lower by oned and there are queued messages for transaction. Mark messages as submitted if the transaction_id is already matching. Do not try to deactivate node on failure here and leave it on proper error path of the caller.
2014-02-24 13:19:50 +04:00
Transaction_id could be lower by one only when messages are prepared.
libdm: call preload callback only when success Do not call node's preload callback, if there is any failure during preload.
2014-02-24 02:10:36 +04:00
Do not call callback when preload fails.
libdm: internal is_selinux_enabled wrapper There is no point to call this external function more then once. (As suggested by selinux developer)
2014-02-20 20:09:55 +04:00
Wrap is_selinux_enabled() to be called just once.
libdm: use 64bit type for raid index Used properly signed 64bit constant for shifting.
2014-02-15 00:13:41 +04:00
Use correctly signed 64b constant when working with raid volumes.
WHATS_NEW: latest commits
2014-02-06 21:19:24 +04:00
Exit dmeventd with pidfile cleanup instead of raising SIGKILL on DIE request.
Add new DM_EVENT_GET_PARAMETERS request to dmeventd protocol.
Do not use systemd's reload for dmeventd restart, use dmeventd -R instead.
WHATS_NEW: be more specific about cryptsetup version that sets the udev flags
2014-01-22 18:48:40 +04:00
Drop cryptsetup rules from 10-dm.rules - cryptsetup >= 1.1.3 sets them.

dmeventd: prevent busy looping on CPU Use usleep when looping on DM_WAIT_RETRY.
2012-03-22 20:00:25 +04:00
Avoid busy looping on CPU when dmeventd reads event DM_WAIT_RETRY.
pre-release
2014-01-20 23:22:56 +04:00
Ensure global mutex is held when working with dmeventd thread.
dmeventd: drop taking timeout mutex Taking _timeout_mutex is not needed when registering and unregistering. Global mutex is already being hold for this case.
2013-06-30 18:06:39 +04:00
Drop taking timeout mutex for un/registering dmeventd monitor.
libdm: prevent empty config file section names Change c35394959758ec17389529f95a33bf7f5b15c56b to use existing _dup_string_tok(). alloca() doesn't fail cleanly (and needs replacing.)
2013-12-05 05:09:03 +04:00
Allow section names in config file data to be quoted strings.
dmeventd: simplify error path Use common 'bad:' label for exit error path where fifo is closed before exit().
2013-11-25 17:24:25 +04:00
Close fifos before exiting in dmeventd restart() error path.
dmeventd: move format text to printf Instead of passing argument with format string to printf(), put the string as arg directly. Also move there remains args to make the code shorter.
2013-11-22 15:54:59 +04:00
Move printf format string directly into dm_asprintf args list.
libdm: catch wrongly reported values Add internal error warning when string value is used as sort value for numerical field. Using log_warn since the function itself does not return error, so we do not confuse log_error() checker.
2013-11-15 15:16:50 +04:00
Catch invalid use of string sort values when reporting numerical fields.

Version 1.02.83 - 13th November 2013
====================================
dmsetup: report error on stderr Send error message on stdout, since after _display_info_long() command return errors. Patch makes consistent behavior for command: dmsetup info -c non-existing-dev & dmsetup info non-existing-dev Now both commands report error on stderr when they return error status for non-existing device.
2013-11-01 15:40:27 +04:00
Consistently report on stderr when device is not found for dmsetup info.
libdm: fix races with udev On modern systems udev manages nodes in /dev/mapper directory. It creates, deletes and renames the nodes according to the state of the kernel driver. When the dmsetup is compiled without udev support (--enable-udev_sync) and runs on the system with running udevd it tries to manage nodes in /dev/mapper too, so it can race with udev. dmsetup checks if the node was created/deleted/renamed with the stat syscall, and skips the operation if it was. However, if udev creates/deletes/renames the node after the stat syscall and before the mknod/unlink/rename syscall, dmsetup reports an error. Since in the system everything happened as expected, skip reporting error for such case. These races can be easily provoked by inserting sleep at appropriate places. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com>
2013-09-16 23:23:54 +04:00
Skip race errors when non-udev dmsetup build runs on udev-enabled system.
libdm: do not show holders missing error On older system this may not be present, so skip this error message.
2013-10-17 13:12:02 +04:00
Skip error message when holders are not present in sysfs.
headers: use __linux__ instead of linux This file may be included by other programs, so it should be compliant with the C standard. * use __linux__ instead of linux - __linux__ is always defined, linux is not defined when gcc runs in standard-compliant mode (with -std=c89 or -std=c99) because the C standard doesn't allow polluting namespace with arbitrary defines. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com>
2013-10-17 13:14:07 +04:00

Version 1.02.82 - 4th October 2013
==================================
libdm: export DM_UDEV_SUBSYSTEM_FLAG names for subystem udev flags Just like we have symbolic names assigned to general DM udev flags (DM_UDEV_* flags), we have the same for any subsystem flags now (DM_SUBSYSTEM_UDEV_FLAG*), making it easier to use.
2013-09-30 13:19:09 +04:00
Define symbolic names for subsystem udev flags in libdevmapper for easier use.
udev: make subsystem rules responsible for importing subsystem flags Each subsystem rule that needs to import any of DM_SUBSYSTEM_UDEV_FLAG* flags is responsible for doing so. This simply moves control of these flags from general 10-dm.rules to any subsystem rule using these flags as each subsystem knows better how to handle these flags on its own.
2013-09-30 13:11:18 +04:00
Make subsystem udev rules responsible for importing DM_SUBSYSTEM_UDEV_FLAG*.

Version 1.02.80 - 20th September 2013
=====================================
dmsetup: Detect invalid sector supplied to message. atoll doesn't check for errors, so invalid sector numbers were silently accepted in the "dmsetup message" command. (Mikulas)
2013-09-18 04:24:19 +04:00
Detect invalid sector supplied to 'dmsetup message'.
libdm: avoid leak if dm_task_set_* fn called again (Mikulas)
2013-09-18 04:13:06 +04:00
Free any previously-set string if a dm_task_set_* function is called again.
libdm: new name can't be empty Do not allow passing '' names to kernel. This test was missing also in kernel, so it has allowed to create device with '' name. This then confused dmsetup tool, since such name is unexpected and unsupported. To remove such name from table, user has to use -j -m to specify which device should be removed. This patch fixes the posibility to run this operation: dmsetup rename existingdev '' after this operation commands like 'dmsetup table' are failing. This patch prohibits to use such name.
2013-08-30 16:46:34 +04:00
Do not allow passing empty new name for dmsetup rename.
dmsetup: display any message output from kernel Recent kernels allow messages to respond with a string. Add dm_task_get_message_response() to libdevmapper to perform some basic sanity checks and return this. Have 'dmsetup message' display any response. DM statistics will make extensive use of this. (From Mikulas.)
2013-08-16 18:25:39 +04:00
Display any output returned by 'dmsetup message'.
Add dm_task_get_message_response to libdevmapper.

Version 1.02.78 - 24th July 2013
================================
libdm: thin pool target sends messages once Clear send_messages flag when they have been delivered successfully. There is no need to validate it for all other activations of the same node in the dm_tree. Also add extra debug message which shows the reason for skipping sending of messages because the transaction_id has already the matching value.
2013-07-15 13:53:30 +04:00
Process thin messages once to active thin pool target for dm_tree.
libdm: remove unneeded read_ahead settings Skip settings are read_ahead value which is already set in kernel.
2013-07-15 13:41:07 +04:00
Optimize out setting the same value or read_ahead.
libdm: add DM_ARRAY_SIZE Add macro for reading detecting size of array.
2013-07-06 22:35:43 +04:00
Add DM_ARRAY_SIZE public macro.
dmeventd: move code from signal handler Instead of calling syslog() from signal event handler, run all logging code in the main loop. Also it needs to take the lock and check for list only when really needed.
2013-06-30 17:53:42 +04:00
Move syslog code out of signal handle in dmeventd.
libdm: add public macro DM_TO_STRING Since this stringifying macro is usable in more places, move it to the public header with DM_ prefix.
2013-05-29 14:46:21 +04:00
Add DM_TO_STRING public macro.
WHATS_NEW: return success on dmeventd -V
2013-05-29 15:24:16 +04:00
Always return success on dmeventd -V command call.
dmeventd: use dm_get_status_snapshot() Switch to use libdm dm_get_status_snapshot() function for reading status info. This fixes bug, where the code was using 32bit integers, while the snapshot target is able to return 64bit sizes. However this also means, someone is using >1TB snapshot cow devices, which is actually very bad idea anyway, since the perfomance and memory usage in this case is very bad.
2013-05-26 19:07:08 +04:00
Fix parsing of 64bit snapshot status in dmeventd snapshot plugin.
libdm: add dm_get_status_snapshot Add dm_get_status_snapshot() for parsing snapshot status.
2013-05-26 18:57:50 +04:00
Add dm_get_status_snapshot() for parsing snapshot status.
libdm: improve detection of mounted fs To detect mounted device, use also /proc/self/mountinfo as so far the check was only able to detect ext4 mounted filesystem. TODO: Once proper testing for this feature is added, it may appear, mountinfo check is enough and covers all cases and sysfs check could be removed.
2013-05-16 13:55:51 +04:00
Detecte mounted fs also via reading /proc/self/mountinfo.
libdm: introduce dm_mountinfo_read Add function for parsing /proc/self/mountinfo entries. This can be used to detected mounted device.
2013-05-16 13:34:26 +04:00
Add dm_mountinfo_read() for parsing /proc/self/mountinfo.
dmeventd: return error if device is not found Do not return 'ok' status if we have failed to found device. (Since it looks like the device is monitored)
2013-04-25 12:17:22 +04:00
Report error for nonexisting devices in dmeventd communication.
dmeventd: prevent double free Since device.name is relased on more places, mark already released name with NULL.
2013-04-19 22:49:57 +04:00
Prevent double free error after dmeventd call of _fill_device_data().
dmeventd: convert union to struct members Sharing char* with field has a problem in error path, when we allocate event, but fail to allocate timeout string. Instead of creating complicated error paths to resolve it individually stop using unions, and let the resource to be released in a simple _free_message().
2013-04-19 22:44:20 +04:00
Update dmevent structure message_data to simplify/fix error path handling.
libdm: validate params for NULL Validate passed params and report error instead of dereferencing NULL passed argument.
2013-04-02 17:01:26 +04:00
Validate passed params to dm_get_status_raid/thin/thin_pool().
dmsetup: fix 'splitname -o' to not fail if used without '-c' This was a regression introduced with e33fd978a8a56228677c14612fce99b3b3588125 (libdm v1.02.68/lvm2 v2.02.89) with the introduction of new output fields blkdevname and blkdevs_used for ls and deps dmsetup commands. A new common '_process_options' fn was added with that commit, but the fn was called prematurely which then broke processing of 'dmsetup splitname -o' which should implicitly use '-c' option and this was failing after the commit: alatyr/~ $ dmsetup splitname -o lv_name /dev/mapper/vg_data-test Option not recognised: lv_name Couldn't process command line. The '-c' had to be used for correct operation: alatyr/~ $ dmsetup splitname -c -o lv_name /dev/mapper/vg_data-test LV test Now fixed to work as it did before: alatyr/~ $ dmsetup splitname -o lv_name /dev/mapper/vg_data-test LV test
2013-03-12 15:37:24 +04:00
Fix 'dmsetup splitname -o' to not fail if used without '-c' switch (1.02.68).
WHATS_NEW: add lines for config validation support
2013-03-06 13:38:40 +04:00
Add dm_config_write_{node_out/one_node_out} for enhanced config output.
Add dm_config_value_is_bool to check for boolean value in supported formats.
config: fix config node lookup inside empty sections to not return the section itself When a section was empty in a configuration tree (no children - this is allowed) and we were looking for a config node inside that section, the _find_config_node function incorrectly returned the section itself if the node inside that section was not found. For example the configuration below: The config: abc { } And a function call to get the "def" node inside "abc" section: _find_config_node(..., "abc/def") ...returned the "abc" node instead of NULL ("def" not found). This in turn caused segfaults in the code using lookups in such a configuration tree as we (correctly) expected that the node returned was always the one we were looking for or NULL if not found. But if incorrect node was returned instead, we processed that as if this was the node we were looking for and so we processed its value as well. But sections don't have values => segfault.
2013-02-27 16:47:57 +04:00
Fix config node lookup inside empty sections to not return the section itself.
text: miscellaneous comments & message tweaks
2013-06-15 04:28:54 +04:00
Append discards and read-only fields to exported struct dm_status_thin_pool.
libdm: fix segault for truncated string token. This patch fixes problem reported here: https://www.redhat.com/archives/dm-devel/2013-January/msg00311.html Fixing it by separating function for duplicating string token. --- When /etc/lvm/lvm.conf is truncated at the first '"' of a line, all LVM utilities crash with a segfault. The segfault only seems to occur if the last character is the first '"' (double quote) of a line. If you truncate it at any other point, lvm detects the error and report parse error lvm.conf ends like this. $hexdump -C lvm.conf .... 69 72 20 3d 20 22 2f 64 65 76 22 0a 0a 0a 20 20 |ir = "/dev"... | 20 20 23 20 41 6e 20 61 72 72 61 79 20 6f 66 20 | # An array of | 64 69 72 65 63 74 6f 72 69 65 73 20 74 68 61 74 |directories that| 20 63 6f 6e 74 61 69 6e 20 74 68 65 20 64 65 76 | contain the dev| 69 63 65 20 6e 6f 64 65 73 20 79 6f 75 20 77 69 |ice nodes you wi| 73 68 0a 20 20 20 20 23 20 74 6f 20 75 73 65 20 |sh. # to use | 77 69 74 68 20 4c 56 4d 32 2e 0a 20 20 20 20 73 |with LVM2.. s| 63 61 6e 20 3d 20 5b 20 22 2f 78 22 2c 0a 20 20 |can = [ "/x",. | 20 20 20 20 20 20 20 20 20 20 20 22 | "| ...

Fix segfault for truncated string token in config file after the first '"'.
dmeventd: close dmeventd FIFO FDs on exec (add FD_CLOEXEC).
2013-01-15 17:59:54 +04:00
Close open dmeventd FIFO file descriptors on exec (FD_CLOEXEC).
thin: dmeventd fix memleak on error path Some error paths on _umount have leaked bitset.
2012-12-13 23:19:38 +04:00
Fix resource leak in error path of dmeventd's umount of thin volume.
libdm: deactivate failed node in preload If the resume of preloaded node fails, do not leave such node in the table - since it may not be easy to detach such node later when the node is i.e. internal. i.e. failing activation of the thin pool with mismatching chunk size may leave -tpool device in the table, which could have been then removed only by dmsetup command.
2012-12-02 19:32:42 +04:00
Automatically deactivate failed preloaded dm tree node.
udev: recognize DM_DISABLE_UDEV environment variable Setting this environment variable will cause a full fallback to old direct node and symlink management in libdevmapper and lvm2. It means: - disabling udev synchronization (--noudevsync in dmsetup and --noudevsync + activation/udev_sync=0 lvm2 config) - disabling dm and any subsystem related udev rules (--noudevrules in dmsetup and activation/udev_rules=0 lvm2 config) - management of nodes/symlinks under /dev directly by libdevmapper/lvm2 (--verifyudev in dmsetup and activation/verify_udev_operations=1 lvm2 config) - not obtaining any device list from udev database (devices/obtain_device_list_from_udev=0 lvm2 config) Note: we could set all of these before - there's no functional change! However the DM_DISABLE_UDEV environment variable is a nice shortcut to make it easier for libdevmapper users so that one can switch off all of the udev management off at one go directly on the command line, without a need to modify any source or add any extra switches.
2012-11-29 17:03:48 +04:00
Add DM_DISABLE_UDEV environment variable to manage dev nodes by libdm only.
udev_sync: cookie_set=1 on each dm_task_set_cookie call cookie_set variable found in the struct dm_task should be always set to 1 after dm_task_set_cookie_call, even if udev_sync is disabled as the cookie itself carries synchronization informations *as well as* extra flags to control other aspects of udev support. For example, one could disable the synchronization itself, but still direct the libdm code to disable library fallback via DM_UDEV_DISABLE_LIBRARY_FALLBACK flag. These extra flags still need to be carried out! A concrete example: $ dmsetup create test --table "0 1 zero" --noudevsync This disables synchronization with udev. As the --verifyudev option is not used, we don't want to do any corrections. In other words, we need DM_UDEV_DISABLE_LIBRARY_FALLBACK flag to be used. However, with --noudevsync this was not the case - the flag was ignored! This patch fixes the case when noudevsync is used but there are still some extra flags passed within the cookie flag part. The synchronization part of the cookie stays zero (which is ok as dm_udev_wait call on such a cookie is simply a NOOP).
2012-10-23 13:40:53 +04:00
Fix dm_task_set_cookie to properly process udev flags if udev_sync disabled.
WHATS_NEW: latest changes under libdm 1.02.78
2012-10-25 18:29:35 +04:00
Version 1.02.77 - 15th October 2012
===================================
thin: add support to unmount volumes Reset counter after thin pool resize failure. If the pool goes above threshold, support unmounting of all thin volumes if the lvextend fails to avoid overfilling of the pool.
2012-03-22 21:29:38 +04:00
Support unmount of thin volumes from pool above thin pool threshold.
WHATS_NEW: update
2012-10-10 19:36:37 +04:00
Update man page to reflect that dm UUIDs are being mangled as well.
Apply 'dmsetup mangle' for dm UUIDs besides dm names.
Add 'mangled_uuid' and 'unmangled_uuid' fields to dmsetup info -c -o.
Mangle device UUID on dm_task_set_uuid/newuuid call if necessary.
Add dm_task_get_uuid_mangled/unmangled to libdevmapper.
release: prepare for release
2012-10-15 18:19:32 +04:00
Always reset delay_resume_if_new flag when stacking thin pool over anything.
config: require dm_config_create_value for dm_config_node's value If we were defining a section (which is a node without a value) and the value was created automatically on dm_config_create_node call, we were wasting resources as the next step after creating the config node itself was assigning NULL for the node's value. The dm_config_node_create + dm_config_create_value sequence should be used instead for settings and dm_config_node_create alone for sections. The majority of the code already used the correct sequence. Though with dm_config_node_create fn creating the value as well, the pool memory was being trashed this way. This patch removes the node value initialization on dm_config_create_node fn call and keeps it for the direct dm_config_create_value fn call.
2012-08-27 16:19:30 +04:00
Don't create value for dm_config_node and require dm_config_create_value call.
dmsetup: check if new_name is non NULL
2012-02-27 04:19:23 +04:00
Check for existing new_name for dmsetup rename.
dmsetup: fix memleak in _get_split_name Free allocated buffer in _get_split_name error path.
2012-08-16 22:12:38 +04:00
Fix memory leak in dmsetup _get_split_name() error path.
release: update version/WHATS_NEW
2012-08-07 23:41:45 +04:00
Version 1.02.76 - 7th August 2012
=================================
Add dm_vasprintf to libdevmapper.
dmsetup: allow --noflush with status/wait for thin Allow --noflush with dmsetup status and wait (for thin target 1.3.0 / ioctl 4.23.0).
2012-07-27 23:03:07 +04:00
Allow --noflush with dmsetup status and wait (for thin target).
config: fix one-node dumpconfig, add dm_config_write_one_node A regression introduced in 2.02.89 (11e520256b3005ed813ce83f8770aaab74edef3f) caused the lvm dumpconfig <node> to print out the node as well as its subsequent siblings. The information about "only_one" mode got lost. Before this patch (just an example node): # lvm dumpconfig global/use_lvmetad use_lvmetad=1 thin_check_executable="/usr/sbin/thin_check" thin_check_options="-q" (...all nodes to the end of the section) With this patch applied: # lvm dumpconfig global/use_lvmetad use_lvmetad=1
2012-07-20 17:53:04 +04:00
Add dm_config_write_one_node to libdevmapper.
release: update version/WHATS_NEW
2012-08-07 23:41:45 +04:00
Support thin pool message release/reserve_metadata_snap in libdevmapper.
thin: use discards as plural rather than singular Global change from --discard to --discards, as that feels more natural.
2012-08-08 00:24:41 +04:00
Support thin pool discards and external origin features in libdevmapper.
udev: udev rules cleanup Remove executable path detection in udev rules and use sbindir that is configured, but still provide the original functionality by means of 'configure --enable-udev-rule-exec-detection'. Normally, the exec path for the tools called in udev rules should not differ from the sbindir used, however, there are cases this is necessary. For example different environments could be assembled in a way that these path differ for some reason (distribution installer, initrd ...). This functionality is kept for compatibility only. Any environment moving the binaries around and using different paths should be fixed eventually!
2012-06-22 13:50:02 +04:00
Add configure --enable-udev-rule-exec-detection to detect exec path in rules.
Use sbindir in udev rules by default and remove executable path detection.
configure: run directory configuration cleanup There were several hard-coded values for run directory around the code. Also, some tools are DM specific only, others are LVM specific and there was no distinction made here before. With this patch applied, we have this cleaned up a bit (subsystem in brackets, defaults in parentheses): [common] configurable PID_DIR (/var/run) lvm [lvm] configurable RUN_DIR (/var/run/lvm) configurable locking dir (/var/lock/lvm) clvmd [lvm] configurable pid file (PID_DIR/clvmd.pid) socket (RUN_DIR/clvmd.sock) lvmetad [lvm] configurable pid file (PID_DIR/lvmetad.pid) socket (RUN_DIR/lvmetad.socket) dm [dm] configurable DM_RUN_DIR (/var/run) cmirrord [dm] configurable pid file (PID_DIR/cmirrord.pid) dmeventd [dm] configurable pid file (PID_DIR/dmeventd.pid) server fifo (DM_RUN_DIR/dmeventd-server) client fifo (DM_RUN_DIR/dmeventd-client) The changes briefly: - added configure --with-default-pid-dir - added configure --with-default-dm-run-dir - added configure --with-lvmetad-pidfile - by default, using one common pid directory for everything (only lvmetad was not following this before)
2012-06-21 16:41:52 +04:00
Remove hard-coded paths for dmeventd fifos and use default-dm-run-dir.
Add configure --with-lvmetad-pidfile to remove hard-coded value.
Add configure --with-default-pid-dir for common directory with pid files.
Add configure --with-default-dm-run-dir to set run directory for dm tools.
release: update version/WHATS_NEW
2012-08-07 23:41:45 +04:00
Detect kernel_send() errors in cmirrord.
Add __attribute__ instrumentation to libdevmapper.h.

===============================
Upstream source repo move to fedorahosted.org git. Change version number suffix from -cvs to -git.
2012-06-06 16:26:46 +04:00
Upstream source repo now fedorahosted.org git not sources.redhat.com CVS.
Remove unsupported udev_get_dev_path libudev call used for checking udev dir. With latest changes in the udev, some deprecated functions were removed from libudev amongst which there was the "udev_get_dev_path" function we used to compare a device directory used in udev and directore set in libdevmapper. The "/dev" is hardcoded in udev now (udev version >= 183). Amongst other changes and from packager's point of view, it's also important to note that the libudev development library ("libudev-devel") could now be a part of the systemd development library ("systemd-devel") because of the udev + systemd merge.
2012-05-29 12:09:10 +04:00
Remove unsupported udev_get_dev_path libudev call used for checking udev dir.
Set delay_resume_if_new on deptree snapshot origin. (Must avoid activating snapshot origin more than once concurrently.)

================================
pre-release
2012-03-06 06:50:40 +04:00
Check for multiply-mangled names in auto mangling mode.
Fix dm_task_get_name_unmangled to not unmangle already unmangled name. In 'auto' and 'hex' mode, these names are already unmangled on ioctl return. There's no point on trying to do that once again (actually it's a bug!).
2012-03-05 16:45:43 +04:00
Fix dm_task_get_name_unmangled to not unmangle already unmangled name.
Check whether device names are properly mangled on ioctl return. Be more strict when unmangling names on ioctl return - require the name to be properly mangled in 'auto' and 'hex' mode. There really should not be any blacklisted character since the names should be renamed already (by means of renaming it directly or running 'dmsetup mangle' for automatic rename).
2012-03-05 16:43:03 +04:00
Check whether device names are properly mangled on ioctl return.
Validate udev structures Avoid using NULL pointers from udev. It seems like some older versions of udev were improperly returning NULL in some case, so do not silently break here, and give at least a warning to the user.
2012-03-04 21:40:59 +04:00

Test _thread_registry list with holding mutex in dmeventd.
pre-release
2012-03-03 05:00:49 +04:00
Add dm_tree_node_set_callback() for preload and deactivation hooks.
Remove support for TRIM message It's been unsupporte for now - and it's not going to be implemented for thin pool kernel driver - so dropping appearence of TRIM from libdm and lvm.
2012-03-02 17:26:08 +04:00
Drop unsupported TRIM message for thin pool.
Improve logging Use %m for strerror. Switch to use 0 for fail return code.
2012-03-02 02:06:18 +04:00
Improve logging for fifo startup in dmeventd.
List _thread_registry missed mutex Operation on _thread_registry needs to be covered by mutex. Cosmetic move a die code after free for valgind short leak list.
2012-03-03 02:57:25 +04:00
Better detection of missing dmeventd fifo connection (1.02.71).
pre-release
2012-03-03 05:00:49 +04:00
Add a few pointer validations in dmsetup.
Check for version string buffer Since lvm seems to call driver_version(NULL, 0) this would lead to crash. Though the combination of the code is probably very hard to hit. If the user doesn't supply version buffer, just skip printing to buffer.
2012-03-01 14:07:38 +04:00
Support dm_task_get_driver_version() query without version string.
Log fail of pthread_join Syslog error outside of mutex section.
2012-03-01 13:50:04 +04:00
Log failure of pthread_join when cleaning unused threads in dmeventd.
Fix empty string warning logic in _find_config_str. (1.02.68) pvcreate gives WARNING: Ignoring unsupported value for metadata/pvmetadataignore. It was warning if there is no config file entry instead of only if the node exists but is empty.
2012-02-28 21:46:47 +04:00
Fix empty string warning logic in _find_config_str. (1.02.68)
Fix dm_task_set_name to properly resolve path to dm name. Wrong variable was checked in _dm_task_set_name_from_path.
2012-02-28 12:36:51 +04:00
Fix dm_task_set_name to properly resolve path to dm name (1.02.71).
Introduce dm_strncpy Should be faster then strncpy - since we could avoid clearing 4KB pages with each strncpy(...,PATH_MAX). Also it's easy to check whether string fit - and eventually avoid to continue working we incomplete string.
2012-02-24 02:45:43 +04:00

====================================
Limit number of mem allocs and copies If we have good enough glibc to return number of needed chars, do not loop try to reach good size, but use this size directly for allocation, saving also last strdup. Since now we start with 16 bytes - skip buffer realloc for shorter string.

2012-02-16 18:39:02 +04:00
Switch to using built-in blkid in 13-dm-disk.rules.
Add watch rule to 13-dm-disk.rules. We don't have anything better yet... The problems the watch rule caused when removing devices should be covered now with the "retry remove" logic. It's also better to have this maintained by us, rather than having this rule anywhere else without proper control.
2012-02-15 18:50:33 +04:00
Add "watch" rule to 13-dm-disk.rules.
Detect failing fifo If the fifo died because of dmeventd restart - do not wait for 20s in select - it will not get better and return error immediately.
2012-02-15 17:56:47 +04:00
Detect failing fifo and skip 20s retry communication period.
pre-release
2012-02-20 23:38:19 +04:00
Add DM_DEFAULT_NAME_MANGLING_MODE environment variable as an override.
Add DM_DEFAULT_NAME_MANGLING_MODE env. variable to override configured value. Just in case of emergency when name mangling code causes any problems so we can override the default value and switch off the mangling globally.
2012-02-15 16:23:15 +04:00
Add dm_lib_init to automatically initialise device-mapper library on load.
post-release
2012-02-21 01:11:06 +04:00
Replace any '\' char with '\\' in dm table specification on input.
Add mangle command to dmsetup to provide renaming to correct mangled form.
2012-02-15 16:08:57 +04:00
Add mangle command to dmsetup to provide renaming to correct mangled form.
Add 'mangled_name' and 'unmangled_name' fields to dmsetup info -c -o.
2012-02-15 16:06:17 +04:00
Add 'mangled_name' and 'unmangled_name' fields to dmsetup info -c -o.
Add --manglename option to dmsetup to select the name mangling mode.
2012-02-15 16:02:58 +04:00
Add --manglename option to dmsetup to select the name mangling mode.
Add dm_task_get_name_mangled/unmangled to libdevmapper. dm_task_get_name_mangled will always return mangled form of the name while the dm_task_get_name_unmangled will always return unmangled form of the name irrespective of the global setting (dm_set/get_name_mangling_mode). This is handy in situations where we need to detect whether the name is already mangled or not. Also display functions make use of it.
2012-02-15 15:39:38 +04:00
Add dm_task_get_name_mangled/unmangled to libdevmapper.
Mangle device name on dm_task_set_name/newname call if necessary. If dm_task_set_name/newname is called, the name provided will be automatically translated to correct encoded form with the hex enconding so any character not on udev whitelist will be mangled with \xNN format where NN is hex value of the character used. By default, the name mangling mode used is the one set during configure with the '--with-default-name-mangling' option.
2012-02-15 15:27:01 +04:00
Mangle device name on dm_task_set_name/newname call if necessary.
Add dm_set/get_name_mangling_mode to set/get name mangling in libdevmapper.
pre-release
2012-02-20 23:38:19 +04:00
Add configure --with-default-name-mangling for udev-friendly dev name charset.
Make sure dereferenced words[0] and words[1] are defined
2012-02-13 18:17:04 +04:00

Ensure allocated device does not leak on error path For unimplementd canonicalize_file_name set to NULL
2012-02-13 16:06:39 +04:00
Fix memory leak in fail path of parse_loop_device_name() in dmsetup.
Check for missing reply_uuid
2012-02-13 15:24:09 +04:00
Check for missing reply_uuid in dm_event_get_registered_device().
Check for allocation failure
2012-02-13 15:18:45 +04:00
Check for allocation failure in dmeventd restart().
Add few missing allocation failures tests
2012-02-13 15:13:44 +04:00
Add few missing allocation failures tests in dmsetup.
Do not write to -1 buffer address In case of zero bytes would be read from sysfs, it would store '\0' on temp_buf[-1] address. Simplify some buffer length calculation and use strcpy if we've just checked string fits in give buffer. Replace jump label error: with bad: commonly used in libdm.
2012-02-13 14:49:28 +04:00
Fix potential risk of writing in front of buffer in _sysfs_get_dm_name().

Version 1.02.70 - 12th February 2012
====================================
Fix message check Check pointer from strchr for NULL instead of crash later. Badly formated message would have crash dmeventd otherwise.
2012-02-10 19:17:52 +04:00
Fix dm_event_get_version() check.
Check for deps pointer before dererence As _deps() call may return NULL - check for it.
2012-02-10 18:48:28 +04:00
Add pointer test for dependency check in _add_dev().
Validate name and uuid params of dm_tree_add_new_dev_with_udev_flags().
Do not crash for NULL sort_key Guard against NULL pointer for sort_key and let it behave like an empty string would have been passed in (i.e. no key).
2012-02-10 18:00:07 +04:00
Do not crash for dm_report_init() sort_key == NULL and behave like "".
Return error for failing allocation Fix case, where final strdup would have failed and it would miss to return failure for this case and return success and NULL pointer.
2012-02-10 17:56:19 +04:00
Return error for failing allocation in dm_asprintf().
Add test for failing allocation Avoid memcpy to NULL if realloc fails.
2012-02-10 17:52:05 +04:00
Add missing test for failing allocation in dm_realloc() code.
Add test for memory allocation failures Replace asserts with test for failing memory allocation. Add at least stack traces. Index counter starts from 1 (0 reserved for error), so replacing fingerprint.
2012-02-10 17:49:29 +04:00
Add test for memory allocation failures in regex matcher code.
Use dm_asprintf to simplify code
2012-02-08 16:59:19 +04:00
Simplify dm_task_set_geometry() and use dm_asprintf().
Set all parameters to 0 Since the function dm_get_next_target() returns NULL as 'next' pointer so it's not a 'real' error - set 0 to all parameters when NULL is returned because of missing head. i.e. one of use case:: do { next = dm_get_next_target(dmt, next, &start, &length, &target_type, &params); size += length; } while (next);
2012-02-08 15:25:09 +04:00
Set all parameters to 0 for dm_get_next_target() for NULL return.
Fix fd resource leak in error path Use 'goto bad' to cleanup fd on error path.
2012-02-08 15:07:17 +04:00
Fix fd resource leak in error path for _udev_notify_sem_create().
Ensure strncpy() function always ends with '\0' Since last character needs to be \0 for string, pass buffer size smaller by 1 byte.
2012-02-08 15:05:04 +04:00
Leave space for '\0' for readline() call in _sysfs_get_kernel_name().

pre-release
2012-01-26 14:11:30 +04:00
Add -o devno/blkdevname/devname to dmsetup deps and ls.
Add dm_device_get_name to get map name or block device name for given devno. This is accomplished by reading associated sysfs information. For a dm device, this is /sys/dev/block/major:minor/dm/name (supported in kernel version >= 2.6.29, for older kernels, the behaviour is the same as for non-dm devices). For a non-dm device, this is a readlink on /sys/dev/block/major:minor, e.g. /sys/dev/block/253:0 --> ../../devices/virtual/block/dm-0. The last component of the path is a proper kernel name (block device name). One can request to read only kernel names by setting the 'prefer_kernel_name' argument if needed.
2012-01-11 16:34:44 +04:00
Add dm_device_get_name to get map name or block device name for given devno.
Add dm_uuid_prefix/dm_set_uuid_prefix for non-lvm users to override hard-coded LVM- prefix. Try harder not to leave stray empty devices around (locally or remotely) when reverting changes after failures while there are inactive tables.
2012-01-10 06:03:31 +04:00
Remove empty devices when clearing left-over inactive tables in deptree.
Add dm_uuid_prefix/dm_set_uuid_prefix to override hard-coded LVM- prefix.
pre-release
2012-01-26 14:11:30 +04:00
Improve dmsetup man page description of readahead parameter.
Use sysfs to set/get readahead if possible.
Fix lvm2-monitor init script to use normalized output when using vgs.
2011-12-07 16:29:41 +04:00
Fix lvm2-monitor init script to use normalized output when using vgs.
Check target type name for DM_MAX_TYPE_NAME length Avoid creation of target type name when it's longer then DM_MAX_TYPE_NAME (noticed by static analyzer where the sp.target_type might be missing '\0' at the end.) Before patch: $> dmsetup create long 0 1000 looooooooooooooooooooooooooong ^D device-mapper: reload ioctl failed: Invalid argument After patch: $> dmsetup create xxx 0 1000 looooooooooooooooooooooooooong Target type name looooooooooooooooooooooooooong is too long. Command failed
2011-11-18 23:34:02 +04:00
Add test for max length (DM_MAX_TYPE_NAME) of target type name.
Include a copy of kernel DM documentation in doc/kernel
2011-11-15 17:54:20 +04:00
Include a copy of kernel DM documentation in doc/kernel.
Add dm_uuid_prefix/dm_set_uuid_prefix for non-lvm users to override hard-coded LVM- prefix. Try harder not to leave stray empty devices around (locally or remotely) when reverting changes after failures while there are inactive tables.
2012-01-10 06:03:31 +04:00

2012-01-26 18:02:42 +04:00
Fix missing thread list manipulation protection in dmeventd.
Add "ExecReload" to dm-event.service for systemd to reload dmeventd properly. Normally, restart simply means "stop and start" for systemd. However, if we're installing new versions of the dmeventd binary/libdevmapper, we need to restart dmeventd. This fails if we have some devices monitored - we need to call "dmeventd -R" instead. The "ExecReload" did not work quite well in some old versions of systemd, systemd assumed that only the configuration is reloaded on "ExecReload", not the whole binary itself so it lost track of dmeventd daemon (it lost new dmeventd PID). This is fixed and seems to be working fine now with recent versions of dmeventd.
2011-10-31 16:22:49 +04:00
Add ExecReload to dm-event.service for systemd to reload dmeventd properly.
Add dm_config_find_str_allow_empty Support empty string values.

Add dm_config_tree_find_str_allow_empty and dm_config_find_str_allow_empty.
Fix usage of DEBUG_ENFORCE_POOL_LOCKING with DEBUG_MEM Since DEBUG_MEM is storing own extra structure within returned memory chunk, glibc free must be used directly for posix_memaling() allocated block.
2011-10-23 19:38:02 +04:00
Fix compile-time pool memory locking with DEBUG_MEM.
Mark chunk memory for free as defined again for valgrind When DEBUG_MEM is used, the memory is trashed with extra pattern before real free() is called, and as this memory was marked as non accessible when used with valgrind, make it again usable.
2011-10-20 17:39:57 +04:00
Fix valgrind error reports in free of pool chunks with DEBUG_MEM.
Aling structure chunk on default aling size Since we use 8 bytes by default for the pool allocation, keep the structure aligned with this size. (Somehow it was not applied in previous commit.)
2011-10-20 18:43:33 +04:00
Align size of structure chunk for fast pool allocator to 8 bytes.
Aling structure chunk on default aling size Since we use 8 bytes by default for the pool allocation, keep the structure aligned with this size.

Fix alignment warning in bitcount calculation for raid segment.
2011-10-17 17:15:35 +04:00
Fix alignment warning in bitcount calculation for raid segment.
Use pool for dm_tree allocation Using the same pool allocation strategy as we use for vg, so dm_tree structure is part of the pool itself.
2011-10-14 17:34:19 +04:00
Allocate dm_tree structure from dm_tree pool.
Update error path tracing for _resume_node dm_task_create & dm_task_set_name produces it's own log_error Add missing stacks for dm_task_set_cookie, dm_task_run, dm_task_get_info.
2011-10-03 22:28:25 +04:00
Update debug logging for _resume_node.

Add dm_device_has_holders fn to to check use of the device by another device. Add dm_device_has_mounted_fs fn to check mounted filesystem on a device. This requires sysfs directory to be correctly set via dm_set_sysfs_dir (/sys by default). If sysfs dir is not used or it's set incorrectly, dm_device_has_{holders,mounted_fs} will return 0!
2011-09-22 21:23:35 +04:00

Remove support for the original version 1 dm ioctls.
Add missing check for allocation failure Static analyzer discovered missing check.
2011-08-04 21:56:11 +04:00
Add missing check for allocation failure _create_dir_recursive().
Add support for systemd file descriptor handover in dmeventd. Systemd preloads file descriptors for us and passes them in for newly spawned daemon when using on-demand fifo (or socket) based activation. This patch adds checks for file descriptors preloaded by systemd and uses them instead of opening the FIFOs again to properly support on-demand FIFO-based activation. (We'll change FIFOs to sockets soon - but still this part of the code will stay almost the same.)

Add age filter to dmsetup udevcomplete_all to minimise concurrency problems.
2011-06-30 01:56:46 +04:00
Add age_in_minutes parameter to dmsetup udevcomplete_all.
Move udev_only logic inside stacked node op code. (We still need to treat add+readhead+del as a no-op.) Rename udev_fallback to verify_udev_operations. Rename --udevfallback to --verifyudev
2011-06-28 01:43:58 +04:00

Report internal error if any table is loaded while any dev is known suspended.
Maintain a count of the number of suspended devices in libdevmapper and use this for the LVM critical section logic. Also report an error if code tries to load a table while any device is known to be in the suspended state. (If the variety of problems these changes are showing up can't be fixed before the next release, the error messages can be reduced to debug level.)
2011-06-13 07:32:45 +04:00
Add dm_get_suspended_counter() for number of devs in suspended state by lib.
Fix 'pvs -o pv_all' to include label fields. (Also removed recursion.)
2011-06-12 23:49:40 +04:00
Fix "all" report field prefix matching to include label fields with pv_all.
Major pvmove fix to issue ioctls in the correct order when multiple LVs are affected by the move. (Currently it's possible for I/O to become trapped between suspended devices amongst other problems. The current fix was selected so as to minimise the testing surface. I hope eventually to replace it with a cleaner one that extends the deptree code. Some lvconvert scenarios still suffer from related problems.

Word alignment for strings Align strdup char* allocation just on 2 bytes. It looks like wasting space to align strings on 8 bytes. (Could be even 1byte - but for hashing it might eventually get better perfomance - but probably hardly measurable). TODO: check on various architectures it's not making any problems.
2011-03-30 16:57:03 +04:00
Use word alignment for dm_pool_strdup() and dm_pool_strndup().

Use dm_snprintf() to fix signedness warning in dm_set_dev_dir().

Const warning fixes With recent update of dm_report_field_string() API call to accept completely const objects - we no longer need loose constness here and keep it forwarding.
2011-03-30 01:49:18 +04:00
Fix const cast in dmsetup calls of dm_report_field_string().
Use hard-coded /dev/mapper/control details for 2.6.36+ kernels and simplify associated code. (Some obscure configurations that happened to work before are no longer supported.)
2011-03-26 02:50:35 +03:00
Streamline /dev/mapper/control node code for common cases.
Use hard-coded dm control node device number for 2.6.36 kernels and above.
Improve debug stack trace dm_check_version reports log_error() - so use return_NULL.
2011-03-18 16:21:02 +03:00
Improve stack debug reporting in dm_task_create().
Mitigate some warnings if running as non-root user. LVM doesn't behave correctly if running as non-root user, there is warning when it detects it. Despite this, it produces many error messages, saying nothing. See https://bugzilla.redhat.com/show_bug.cgi?id=620571 This patch fixes two things: 1) Removes eror message from device_is_usable() which has no information value anyway (real warning is printed inside it). 2) it fixes device-mapper initialization, if we support core dm module autoload and device node is present, it should fail early and not try recreate existing and correct node. (non-root == permission denied here) N.B. In future code should support user roles, some more drastic checks in code are probably contraproductive now.

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.

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.

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!

2010-08-16 15:22:08 +04:00
Assume dm-mod autoloading support is in kernel 2.6.36 and higher, not 2.6.35.
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.

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).

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.

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.

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.

=================================
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.

Version 1.02.46 - 14th April 2010
=================================
Fix incorrect removal of symlinks after LV deactivation fails.
2010-04-08 00:04:41 +04:00
Change dm_tree_deactivate_children to fail if device is open.
Wipe memory buffers for dm-ioctl parameters before releasing.
Strictly require libudev if udev_sync is used. This prevents some confusion when libudev was not found so udev_sync was disabled automatically. Configure was successful though giving only a tiny warning. Also, if "dmsetup udevcreatecookie" is used, never return 0x000000 as a result if udev is not running and keep the output blank.
2010-03-23 17:43:18 +03:00
Strictly require libudev if udev_sync is used.
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.
2010-03-23 17:38:37 +03:00
Add support for ioctl's DM_UEVENT_GENERATED_FLAG.

Version 1.02.44 - 15th February 2010
====================================
Several changes in dmsetup and libdevmapper: - add DM_UDEV_DISABLE_LIBRARY_FALLBACK udev flag to rely on udev only - export dm_udev_create_cookie function to create new cookies on demand - add --udevcookie, udevcreatecookie and udevreleasecookie for dmsetup (to support "udev transactions" where one cookie value can be used for several dmsetup calls) - don't use DM_UDEV_DISABLE_CHECKING env. var. anymore and set the state automatically (based on udev and libdevmapper dev path comparison)
2010-02-15 19:21:33 +03:00

2009-12-11 16:11:56 +03:00
Fix coredump and memory leak for 'dmsetup help -c'.
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.
2009-12-07 15:03:47 +03:00
Disable udev rules for change events with DISK_RO set.
Post-release. Fingers crossed this one's more successful that the last one!

====================================
Fix install_device-mapper Makefile target to not build dmeventd plugins.
2009-11-13 15:48:01 +03:00
Fix install_device-mapper Makefile target to not build dmeventd plugins.
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).
2009-11-13 15:43:21 +03:00
Support udev flags even when udev_sync is disabled or not compiled in.
.
2009-11-19 22:42:57 +03:00
Remove 'last_rule' from udev rules: honour DM_UDEV_DISABLE_OTHER_RULES_FLAG.
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).
2009-11-06 03:43:08 +03:00
Add dmsetup --inactive support.

Version 1.02.39 - 26th October 2009
===================================
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)
2009-10-22 17:11:33 +04:00
Remove strict default permissions for DM devices from 95-dm-notify.rules.
Add udev flags support in libdevmapper and provide 'dmsetup udevflags' command to decode them.

Version 1.02.30 - 26th January 2009
post-release (retrospective)
2008-11-19 17:14:51 +03:00
====================================
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.
2009-01-10 06:01:35 +03:00
