6.2.0.273

Version 6.2.0.273

Note: This is a pre-release version, future versions of VDO may not support
VDO devices created with this version.
- Fixed more error path memory leaks in the uds and kvdo modules.
- Fixed module loading issues with the spec file on Fedora.
- Removed the read cache.
- Fixed error handling in preresume.
- Converted table line parsing to use existing DM functions.
- Fixed a bug which prevented parsing of version 0 table lines.
- In order to properly handle version 0 table lines, made no-op physical
  growth not an error.
- Limited the number of logical zones to 60.
- Converted to use the kernel's bio zeroing method instead of a VDO
  specific one.
- Added a missing call to flush_cache_page() after writing pages which may
  be owned by the page cache or a user as required by the kernel.
- Added a version 2 table line which uses DM-style optional parameters.
- Fixed a bug in the statistics tracking partial I/Os.
- Added a maximum discard size table line parameter and removed the
  corresponding sysfs parameter which applied to all VDO devices.

6.2.0.239

Version 6.2.0.239

Note: This is a pre-release version, future versions of VDO may not support
VDO devices created with this version.
- Fixed error path memory leaks in the uds and kvdo modules.
- Modified the physical and logical growth procedures to be consistent with
  other device mapper targets.

6.1.0.187

Version 6.1.0.187

- Fixed a hang when recovering a VDO volume with a physical size larger
  than 16TB.

6.2.0.219

Version 6.2.0.219

Note: This is a pre-release version, future versions of VDO may not support
VDO devices created with this version.
- Fixed error path memory leaks in the uds and kvdo modules.
- Fixed conflict errors when installing RPMs via dnf.
- Fixed a hang when recovering a VDO volume with a physical size larger
  than 16TB.
- Fixed some potential initialization issues in the UDS module.
- Fixed a use-after-free bug in a UDS error path.
- Added missing va_end() calls.
- Modified Makefile to take build flags from rpmbuild.

6.1.1.125

Version 6.1.1.125

- Fixed a hang when recovering a VDO volume with a physical size larger
  than 16TB.

6.1.0.185

Version 6.1.0.185

- Fixed a potential stack overflow when reaping the recovery journal.

6.2.0.197

Version 6.2.0.197

Note: This is a pre-release version, future versions of VDO may not support
VDO devices created with this version.
- Enabled the setting of max_discard_sectors for VDO devices via sysfs.
  This allows users stacking dm-thin devices on top of VDO to set a value
  which is large enough that dm-thin will send discards to VDO.

6.1.1.120

Version 6.1.1.120

• Improved memory allocation by not using the incorrect __GFP_NORETRY flag
  and by using the memalloc_noio_save mechanism.
• Fixed a potential deadlock in the UDS index by using the kernel supplied
  struct callback instead of our own implementation of synchronous
  callbacks.
• Fixed a potential stack overflow when reaping the recovery journal.

6.2.0.187

Version 6.2.0.187

Note: This is a pre-release version, future versions of VDO may not support
VDO devices created with this version.
- Fixed a potential deadlock in the UDS index by using the kernel supplied
  struct callback instead of our own implementation of synchronous
  callbacks.
- Eliminated obsolete code and fields from UDS.
- Converted the VDO module to use numeric.h from the UDS module instead of
  having its own version.
- Fixed a bug which would cause incorrect encoding of VDO data structures
  on disk.
- Removed or modified logging which prints pointers from the kernel since
  newer kernels obfuscate the pointer values for security reasons.
- Eliminated confusing and spurious error messages when rebuilding a UDS
  index.
- Improved memory allocation by not using the incorrect __GFP_NORETRY flag
  and by using the memalloc_noio_save mechanism.
- Finished conversion of the encoding and decoding of the VDO's on-disk
  structures to be platform independent.
- Converted VDO to use the atomic API from the UDS module instead of its
  own.
- Fixed memory leaks in UDS error paths.
- Fixed a potential stack overflow when reaping the recovery journal.

6.1.0.181

Version 6.1.0.181

- Fixed a bug which would cause kernel panics when a VDO device is stacked
  on a RAID50 device.
- Fixed a bug which could cause data loss when discarding unused portions
  of a VDO's logical space.
- Modified grow physical to fail in the prepare step if the size isn't
  changing, avoiding a suspend-and-resume cycle.
