TBD Oracle, Inc. * version 3.3.0 Severity : enhancement Bugzilla : 17670 Description: FID_in_Dirent feature for OSD. Details : Support for storing the FID in the directory entry has been added to ext3 and ext4. ------------------------------------------------------------------------------- 2010-07-15 Oracle, Inc. * version 3.2.0 Severity : enhancement Bugzilla : 17670 Description: FID_in_Dirent feature for OSD. Details : Support for storing the FID in the directory entry has been added to ext3 and ext4. ------------------------------------------------------------------------------- 2009-11-05 Sun Microsystems, Inc. * version 3.1.0 Severity : normal Frequency : in recovery Bugzilla : 21031 Description: ext3-corrupted-orphans-2.6.patch added. Details : Backport of ext3 patch to handle corrupted orphans. ------------------------------------------------------------------------------- 2009-07-31 Sun Microsystems, Inc. * version 3.0.9 Severity : minor Frequency : in recovery Bugzilla : 18192 Description: don't mix llog inodes with normal. Details : allocate inodes for log in last inode group ------------------------------------------------------------------------------- 2009-04-20 Sun Microsystems, Inc. * version 3.0.8 Severity : minor Bugzilla : 16114 Description: minor fixes and cleanups Details : use EXT_UNSET_BLOCK to avoid confusion with EXT_MAX_BLOCK. Initialize 'ix' variable in extents patch to stop compiler warning. Severity : feature Bugzilla : 17942 Description: update FIEMAP ioctl to match upstream kernel version Details : the FIEMAP block-mapping ioctl had a prototype version in ldiskfs 3.0.7 but this release updates it to match the interface in the upstream kernel, with a new ioctl number. Severity : normal Frequency : only if MMP is active and detects filesystem is in use Bugzilla : 18173 Description: if MMP startup fails, an oops is triggered Details : if ldiskfs mounting doesn't succeed the error handling doesn't clean up the MMP data correctly, causing an oops. ------------------------------------------------------------------------------- 2009-04-06 Sun Microsystems, Inc. * version 3.0.7.1 Severity : major Frequency : rare Bugzilla : 18810 Description: fix racy locking of mballoc block bitmaps causing BUG Details : The locking of the mballoc buddy bitmap and the in-memory block bitmap was using two different spin locks in some cases. This made it possible to incorrectly access the mballoc bitmap while another process was modifying it, causing a sanity assertion to fail. While no on-disk corruption was reported, there was some risk of this happening. ------------------------------------------------------------------------------- 2009-02-07 Sun Microsystems, Inc. * version 3.0.7 Severity : enhancement Bugzilla : 16498 Description: Get RAID stripe size from superblock Details : RAID striping parameters are now saved in the superblock itself, so we should use these parameters instead of having to specify a mount option each time. Severity : major Frequency : only if server is running on unsupported big-endian machine Bugzilla : 16438 Description: Disable big-endian ldiskfs server support. Details : The ldiskfs code is not tested on big-endian machines, and there are known compatibility problems in the extents code when running for most of the kernels. Print an error message and refuse to mount, in case anyone tests this. For existing filesystems that might have been created in this way it is possible to mount with the "bigendian_extents" option to force the mount. Severity : major Frequency : only with software RAID-5 Bugzilla : 17895 Description: MMP block reads may fail to detect another user of the filesystem Details : with software RAID it is possible that the RAID driver will cache the MMP block and not refetch it from disk. Force the read to invalidate the RAID page cache and go directly to disk. ------------------------------------------------------------------------------- 2008-08-31 Sun Microsystems, Inc. * version 3.0.6 Severity : enhancement Bugzilla : 11826 Description: Interoperability at server side (Disk interoperability) Details : Exported some ldiskfs functions which are required for iop Severity : normal Bugzilla : 15320 Description: OSS crashes frequently, e2fsck does not fix Details : Add an extra check to ldiskfs extents code for the condition, eh_entries = 0 & eh_depth != 0 Severity : normal Bugzilla : 15459 Description: migrate ldiskfs - ldiskfs2 (extents on directories) Details : disable preallocation for non-regular files. Severity : normal Frequency : blocks per group < blocksize*8 and uninit_groups is enabled Bugzilla : 15932 Description: ldiskfs error: XXX blocks in bitmap, YYY in gd Details : If blocks per group is less than blocksize*8, set rest of the bitmap to 1. Severity : normal Frequency : only for filesystems larger than 8TB Bugzilla : 16101 Description: ldiskfs BUG ldiskfs_mb_use_best_found() Details : The ldiskfs mballoc3 code was using a __u16 to store the group number, but with 8TB+ filesystems there are more than 65536 groups, causing an oops. Severity : enhancement Bugzilla : 10555 Description: Add a FIEMAP(FIle Extent MAP) ioctl for ldiskfs Details : FIEMAP ioctl will allow an application to efficiently fetch the extent information of a file. It can be used to map logical blocks in a file to physical blocks in the block device. Severity : normal Bugzilla : 17490 Description: mkfs.lustre: Unable to mount /dev/cciss/c0d1:Cannot allocate memory Details : correctly handle device paths using a subdirectory in /dev when creating the per-device procfs directory under /proc/fs/ldiskfs. ------------------------------------------------------------------------------- 2008-04-26 Sun Microsystems, Inc. * version 3.0.5 Severity : normal Bugzilla : 14493 Description: Kernel BUG at ... ldiskfs/ldiskfs/mballoc.c:3853 Details : Removing the underlying device (e.g. via a SCSI rescan) can cause a kernel BUG in ldiskfs_mb_discard_inode_preallocations(). Severity : major Bugzilla : 14596 Description: deadlock in ext3_expand_extra_isize Details : Inode expansion during ext3_mark_inode_dirty may lead to deadlock. This is solved by making sure that ext3_expand_extra_isize isn't called from ext3_xattr_set_handle. Severity : normal Bugzilla : 14594 Description: soft lockups on 1.6.2 MDS (is_subdir) Details : don't add dentries with ".." to dcache and ignore such dentries in iopen_lookup(). Severity : critical Frequency : very rare, if additional xattrs are used on kernels >= 2.6.12 Bugzilla : 15777 Description: files may lose file attributes in some cases Details : If there are multiple extended attributes stored on the inode, in particular ACLs, SELinux, or user attributes (if user_xattr is specified for the client mount options) then there is a risk of attribute loss. If an additional attribute is be stored initially in the inode and then increase in size enough to be moved to the external attribute block (e.g. ACL growing in size) for the attribute to be lost. Severity : normal Bugzilla : 15604 Description: inode version not being initialized on new inodes Details : The inode i_version field was not being initialized on disk. This field is currently unused but will be needed for VBR. -------------------------------------------------------------------------------- 2008-01-11 Sun Microsystems, Inc. * version 3.0.4 Severity : normal Bugzilla : 13397 Description: Add support for vanilla-2.6.22 kernel. -------------------------------------------------------------------------------- 2007-12-07 Cluster File Systems, Inc. * version 3.0.3 Severity : normal Bugzilla : 13164 Description: statfs speedup patches. Details : The patches improve statfs performance for very large filesystems. Severity : normal Frequency : if the uninit_groups feature is enabled on ldiskfs Bugzilla : 13706 Description: e2fsck reports "invalid unused inodes count" Details : If a new ldiskfs filesystem is created with the "uninit_groups" feature and only a single inode is created in a group then the "bg_unused_inodes" count is incorrectly updated. Creating a second inode in that group would update it correctly. -------------------------------------------------------------------------------- 2007-09-27 Cluster File Systems, Inc. * version 3.0.2 Severity : enhancement Bugzilla : 10555 Description: Add a FIEMAP(FIle Extent MAP) ioctl for ldiskfs Details : FIEMAP ioctl will allow an application to efficiently fetch the extent information of a file. It can be used to map logical blocks in a file to physical blocks in the block device. -------------------------------------------------------------------------------- 2007-08-29 Cluster File Systems, Inc. * version 3.0.1 Severity : major Frequency : rare Bugzilla : 6334 Description: Multiple mount protection(MMP) support. Details : This feature will protect the filesystem from being mounted more than once simultaneously. It will also protect changes by e2fsprogs to the filesystem if it is mounted. This assumes high importance in a shared storage environment where multiple mounts can severely corrupt the filesystem. -------------------------------------------------------------------------------- 2007-08-10 Cluster File Systems, Inc. * version 3.0.0 * Initial release of ldiskfs as a separate package. Severity : normal Frequency : rare Bugzilla : 12415 Description: Updated patchess for new RHEL4 kernel Details : Add patch ext3-unlink-race.patch Updated series file ldiskfs-2.6-rhel4.series
