It can be used to convert a +filesystem into using or not using FILETYPE feature. + +E2fsck now properly handles filesystems that have the IMAGIC feature +turned on (this is used on Linux AFS servers). + +The mke2fs program now creates filesystems that have the filetype and +sparse_superblock features enabled by default, unless it is run on a +pre-2.2 kernel. These features are not supported by a pre-2.2 kernel, +so there is now a new flag -O which allows the user to specify with +which features she would like to create the filesystem; "mke2fs -O +none" will create a filesystem compatible with 2.0 kernels. + +The tune2fs program now has a -O option which allows the user to set +and reset "safe" filesystem features. Currently, the only ones which +allows to be modified are the filetype and sparse_superblock features. +Note setting or clearing either feature will require running e2fsck on +the filesystem afterwards. (n.b. Clearing the sparse_superblock feature +requires that there is enough free space on the filesystem for the +extra superblocks which will be created by e2fsck.) + +Debugfs can now set and print filesystem features in the superblock +using the "features" command. Dumpe2fs will print out the complete +set of features when listing the superblock. + +Dumpe2fs has new options -f (force) and -h (header-only). + +Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead +message to come up. This could happen when decrementing or +incrementing a link count could result in an overflow. + +Fixed a bug in e2fsck where the block count on the lost+found +directory would not be properly incremented when the directory was +expanded to the point where an indirect block needed to be allocated. + +E2fsck now makes some additional sanity checks on the superblock to +avoid crashing or giving a memory allocation error if some of the +values in the superblock are unreasonable (but the superblock otherwise +looks valid). + +Fixed a bug in e2fsck where a very badly corrupted filesystem might +require two passes to completely fix the filesystem. This happened if +an inode claimed blocks that was part of the filesystem metadata +(typically, when garbage was written into an inode table or indirect +block, since this kind of filesystem corruption normally doesn't +happen otherwise). + +On the Alpha, glibc declares st_flags although it isn't actually used; +the configure script was improved to detect this case so that +e2fsprogs can avoid using the non-functional stat field. + +The manual pages were updated to use a more consistent formatting +style consistent with standard Unix man pages. Mke2fs's man page +added documentation for a few previously undocumented options. + +Fixed minor display bugs in tune2fs and mke2fs. + +Programmer's notes: +------------------- + +Improved portability of e2fsprogs to non-Unix systems (in particular, NT). + +Added features to parse and print feature strings into the e2p library. +(e2p_feature2string, e2p_string2feature, e2p_edit_feature). + +ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories +whose directory entries contain proper filetype information if the +filesystem supports it. + +ext2fs_link() now uses the low 3 bits of its flags parameter to pass +the directory entry filetype information. This is used to set the +directory entry filetype information if the filesystem supports it. + +Fixed a bug in ext2fs_expand_dir() where the block count in a +directory's inode would not be properly incremented when the directory +was expanded to the point where an indirect block needed to be +allocated. + |
