Release notes for the e2fsprogs package

+

E2fsprogs 1.42.1 (February 17, 2011)

+ +

The mke2fs and e2fsck now use significantly less memory when creating +or checking very large file systems. This was enabled by adding +extent-based bitmaps which are stored using a red-block tree, since +block and inode allocations tend to be contiguous.

+ +

The command mke2fs -S is used as a last ditch recovery command to +write new superblock and block group descriptors, but _not_ to destroy +the inode table in hopes of recovering from a badly corrupted file +system. So if the uninit_bg feature is enabled, mke2fs -S will now +set the unused inodes count field to zero. Otherwise, e2fsck -fy +after using mke2fs -S would leave the file system completely empty.

+ +

Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also +honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has +installed an mke2fs binary using that name.

+ +

The usage and help messages for the -G, -t and -T options in mke2fs +have been fixed.

+ +

If e2fsck needs to use the backup group descriptors, the +ext2fs_open2() function clears the UNINIT bits to ensure all of the +inodes in the file systems get scanned. However, the code which reset +the UNINIT flags did not also recalculate the checksum, which produced +many spurious (and scary) e2fsck messages. This has been fixed by +resetting cheksums when the UNINIT bits are cleared.

+ +

Relax a check in e2fsck which required that the block bitmap to be +initialized when the inode bitmap is in use. This will allow us to +eventually eliminate code from the kernel which forcibly initialized +the block bitmap when the inode bitmap is first used, requiring an +extra journal credit and disk write. (Addresses Google Bug: #5944440)

+ +

Make sure rdebugfs (which may be installed setuid or setgid disk) does +not honor environment variables if euid != uid or egid != gid.

+ +

Debugfs's ncheck command has been optimized and now is much more +robust with faced with corrupted file systems. The ncheck command +also now has a -c option which will verify the file type information +in the directory entry to see if matches the inode's mode bits. This +is extremely useful when trying to use debugsfs to determine which +parts of the file system metadata can be trusted.

+ +

E2image will try to use ftruncate64() to set the i_size for raw +images, instead of writing a single null byte. This avoid allocating +an extra block to the raw image, for those file systems and/or +operating systems that support this. (Linux does.) In addition, fix +a logic bug that caused the file to not be properly extended if the +size of the last hole was exactly an multiple of a megabyte.

+ +

Fixed a bug in resize2fs where for 1k and 2k file systems, where +s_first_data_block is non-zero, this wasn't taken into account when +calculate the minimum file system size for use with the -M option.

+ +

Fixed the badblocks program to honor the -s flag when in read-only -t +mode. (Addresses Debian Bug #646629)

+ +

Update Czech, Dutch, French, Polish, and Sweedish translation from the +Translation Project.

+ +

Fixed various Debian Packaging issues so that dpkg-buildflags is used +if present, which allows e2fsprogs to be built with security hardening +flags. (Addresses Debian Bugs: #654457)

+ +

Programmer's Notes

+ +

Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps. +This was only an issue for programs compiled against e2fsprogs 1.41 +that manipulate bitmaps directly. (Addresses Sourceforge Bugs: +#3451486)

+ +

The libext2fs library now uses sysconf() to fetch the page size, instead +of the deprecated getpagesize().

+ +

The ext2fs_get_pathname() function will return a partial path if an a +directory in the path is not a directory, displaying it as an inode +number in angle brackets instead of giving up and displaying an error. +This is much more helpful when a user is trying to debug a corrupted +file system.

+ +

Codepoints for the RO_COMPAT_REPLICA feature has been reserved.

+ +

Added a new library function, ext2fs_file_get_inode_num(), for use by +fuse2fs.

+ +

Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a +file, it actually works.

+ +

The block iterator now properly honors the BLOCK_ABORT flag for +extent-based flags. Previously, it didn't, which generally made code +be less efficient, but it could cause bugs in ext2fs_link(), for +example, by causing it to insert multiple directory entries.

+ +

Fixed an (harmless other than causing a compiler warning) use of an +uninitialized variable in e2fsck's MMP code.

+ +
