| E2fsprogs 1.44.0 (March 7, 2018) |
| ================================ |
| |
| Updates/Fixes since v1.43.9: |
| |
| UI and Features |
| --------------- |
| |
| E2fsprogs now supports the large_dir (INCOMPAT_LARGEDIR) feature. This |
| feature allows larger directories to be created, both with directory |
| sizes over 2GB and and a maximum htree depth of 3 instead of the |
| current limit of 2. These features are needed in order to exceed |
| the currently limit of approximately 10M entries in a single |
| directory for 4KB blocksize (~100k for 1KB). |
| |
| E2fsprogs now supports the ea_inode (INCOMPAT_EA_INODE) feature, which |
| stores large extended attributes in an external inode instead of a |
| single data block. This is backwards compatible with a Lustre file |
| system feature, but it has been extended to support deduplicating |
| extended attribute values which are used in multiple inodes. |
| |
| The metadata_csum feature (RO_COMPAT_METADATA_CSUM) is now enabled by |
| default by mke2fs. |
| |
| The resize2fs program will no longer complain about resizing bigalloc |
| file systems as being dangerous when doing an on-line resize (since this |
| is purely a kernel feature). |
| |
| Debugfs's ls command will now print the high bits of the inode's mode |
| bits. |
| |
| Fixes |
| ----- |
| |
| Fixed some potential buffer overrun bugs in the blkid library and in the |
| fsck program. |
| |
| There were some corner cases which tune2fs wouldn't correctly handle |
| when operating on a file system which was not cleanly mounted and thus |
| required running the journal because it could be modified. Tune2fs will |
| now run the journal before trying to change the superblock, and if the |
| file system needs to be checked after the journal has been replayed, it |
| will require it before proceeding. Also if the file system is busy (for |
| example, because it is in use by Lustre), but is not present in the |
| /proc/mounts or /etc/mtab, tune2fs will not try to replay the journal, |
| since this could do real damage if it the file system is being actively |
| modified by the kernel. |
| |
| The libss library (used by debugfs) now supports the version 7 of the |
| libreadline shared library. |
| |
| The e2freefrag program will use the GETFSMAP ioctl if it is available |
| and the file system is mounted, so that the free space statistics will |
| be more accurate. |
| |
| The consistency checks for symlinks (especially for encrypted and inline |
| data file sytems) in e2fsck are now much more careful/stringent. Also |
| fixed a bug where creating a symlink using ext2fs_symlink() which was |
| exactly 60 bytes long when inline data was enabled would result in a |
| missing system.data xattr. |
| |
| |
| Performance, Internal Implementation, Development Support etc. |
| -------------------------------------------------------------- |
| |
| Mke2fs now uses io_channel_flush() instead of sync() for the sync_kludge |
| feature. |
| |
| E2fsprogs now uses i_size as the primary way of determining whether a |
| symlink is a fast symlink. |
| |
| Fix various compiler and UBSAN warnings. |
| |
| Long running test are now skipped with "make check" and only run when |
| "make fullcheck". The test runner will warn when potentially long |
| running tests are being run via "make check". |
| |
| E2fsck is now much faster for bigalloc file systems when scanning |
| extents for bigalloc file systems. (Addresses Google Bug #36886699) |
| |
| Update Czech, Spanish, French, Malay, and Ukrainian translations. |
