dmstats: fix parsing of list regions

Replace %4095c sscanf format specifier with position-based copying.

The _stats_parse_list_region() function previously used %4095c to read
the remaining part of the input buffer. Recent glibc versions
(2.42.9000-3.fc44) have changed the behavior of this format
specifier to align with C standard specifications, which affects
parsing when the buffer contains fewer than 4095 characters.

To ensure compatibility across different glibc versions, switch to
using %n to track the parsing position and manually copy the string
data using dm_strncpy().

Note: Binaries compiled with the previous implementation may experience
compatibility issues with newer glibc versions.

2. run, which removes pr key from the VG devices,

still possible.)

When another key exists, removing the local PR key will cause the

is written for vgremove.  The prepare step must remain at the beginning
of the command, while the list of PVs in the VG still exists.

1. **Timer reset bug**: Threads exiting grace period were starting

   in behavior and firing monitor action in non-deterministic time.
   Reset timer (next_time = current_time + timeout) AFTER grace
   period wait.

2. **Device identity verification**: Add inode tracking to prevent
   incorrect thread reuse when device UUID is recycled. Grace period
   thread lookup now verifies device inode matches to ensure same
   physical device. This avoid reusing of monitored values for
   a different device.
   'diskseq' was also considered as unique identifier, but inode
   check seems to be easier to check and is not 'so new'.
   Also another solution could have been to change dmeventd protocol,
   and introduce supend/resume calls - but this could be another source
   of problem.

3. **Signal handling order**: Move SIGALRM reset to occur BEFORE
   entering grace period instead of after. This prevents potential
   error path trouble that may have shutdown reused thread causing
   the actual monitoring to be silently lost.

4. **Event state cleanup**: Clear current_events before grace period

dmeventd: add thread grace period for monitoring

Add thread reuse mechanism to reduce overhead when devices are frequently
registered/unregistered by introducing a configurable grace period where
monitoring threads wait for potential reuse before termination.

Key changes:
- Add -g option to configure grace period (0-300 seconds, default: 10s)
- Introduce DM_THREAD_GRACE_PERIOD state for threads awaiting reuse
- Implement thread reuse for matching device/dso combinations
- Add pthread condition variables and mutexes for grace period synchronization
- Add thread usage counter and enhanced debug logging
- Add _reset_pending_signal() to handle SIGALRM cleanup on thread reuse
- Refactor _monitor_thread() to support grace period workflow
- Update timeout thread to skip non-running threads
- Simplify thin plugin logging

This optimization significantly reduces thread creation/destruction overhead
in scenarios with rapid device registration/unregistration cycles, such as
creating snapshots of thin volumes, while maintaining proper cleanup and
thread safety.

dmeventd: add device existence check

Add device existence check after successful wait ioctl to prevent
processing events on removed devices.

When dm_task_run() succeeds on a WAITEVENT ioctl, the success might
actually indicate that the device was removed rather than a genuine
device event. Without this check, dmeventd would attempt to process
ERROR events on non-existent devices, leading to unnecessary error
commands and log noise.

This fix adds a _fill_device_data() call immediately after successful
wait completion to verify the device still exists. If the device is
gone, execution jumps to the existing ENXIO error path which properly
handles device disappearance.

Note: Future kernel versions may return ENXIO directly from the wait
ioctl when devices are removed, making this workaround unnecessary.

Break down complex one-liner directory check into explicit steps with

The original code used a dense subshell expression combining multiple
tests with logical operators, making it difficult to understand and
maintain. This refactoring separates the logic into:

1. Check directory accessibility (read/write/execute permissions)
2. Check if directory is empty (including hidden files)

Each check now has a specific error message, making it easier for users
to understand what went wrong. The functionality remains identical, but
the code is now more maintainable and debuggable.

Changes:
- Split accessibility and emptiness checks into separate if statements
- Add descriptive comments explaining each validation step
- Provide specific error messages for different failure conditions
- Maintain original behavior including dotglob/nullglob handling

test: fix skipping of this repair test

Fix the usage of delay_dev so the test is properly executed
and not skiped. For major mirror slowdown use smalled region
sizes that are cause way more frequent commits so we can go
with significantly smaller delays.

Also check repair to work for failing mirror leg and mirror log.

4 months agotest: refactor lvconvert-raid-reshape-size.sh
Heinz Mauelshagen [Fri, 4 Jul 2025 20:11:05 +0000 (22:11 +0200)]
test: refactor lvconvert-raid-reshape-size.sh

Improve the RAID reshape size test script with the following changes:

**Code Quality Improvements:**
- Add proper shell quoting throughout the script to prevent word splitting issues
- Replace manual arithmetic with cleaner shell arithmetic syntax
- Improve variable handling and remove unnecessary local variable assignments
- Fix typo: "hilesystem" -> "filesystem"

**Test Reliability Enhancements:**
- Add EXTENSIVE_FSCK environment variable for optional additional filesystem validation
- Reduce delay times from 40ms/25ms to 20ms for all RAID types to speed up testing
- Add helper functions _delay_dev() and _restore_dev() for cleaner device delay management
- Use --noudevsync flag in lvconvert to avoid udev-related timing issues
- Remove unnecessary sleep calls and udevadm settle commands

**Functionality Improvements:**
- Improve _check_size() function to return proper exit codes instead of echo statements
- Better error handling in conditional statements using proper test syntax
- Cleaner parameter passing using "$@" instead of manual argument handling
- More robust device path handling using $DM_DEV_DIR consistently

**Code Structure:**
- Extract device delay logic into reusable helper functions
- Improve readability with better variable naming and consistent formatting
- Add explanatory comments for complex operations
