In addition, the mke2fs output has been +made much less verbose and only displays information that users will +be more likely to find useful by default.</P> + +<P>Mke2fs now will ask the user to confirm that they want to continue +before wiping out a pre-existing file system, partition table, or LVM +physical volume.</P> + +<P>Mke2fs now has the ability to create file systems where all the +metadata is located at the very beginning of the device. This can be +useful for flash devices which have SLC flash at the beginning of the +disk, for FAT compatibility, for example. As part of this, mke2fs and +tune2fs can control the location of the data blocks used by the +journal inode. In addition, the new sparse_super2 feature allows for +even fewer (anywhere from zero to two) backup superblocks.</P> + +<P>Mke2fs now uses much less CPU when allocating the blocks used for very +large file systems.</P> + +<P>Mke2fs can now support creating a file system at an offset. This can +be useful when creating a disk image for virtual machines (Addresses +Debian Bug: #497984)</P> + +<P>Previously, e2fsck had a number of very serious bugs when checking a +file system wich used the new the quota file system option (where the +quota inodes were stored in hidden inodes) and the quota inode was +inconsistent with the actual usage data. This problem was documented +in https://ext4.wiki.kernel.org/index.php/Quota. These problems have +been fixed in 1.42.10, so the quota should be safe to use with +e2fsprogs 1.42.10.</P> + +<P>Fixed in a bug in resize2fs which could cause shrink operation fail in +the unlikely situation when the inode table needs to be moved to a +location before the current location.</P> + +<P>Resize2fs now has a much more accurate (and less conservative) +estimation of how far the file system can be shrunk. This allows a +mostly empty filesystem which is a few terabytes, to be shrunk to a +few megabytes in a single resize2fs -M operation.</P> + +<P>E2fsck will now force a full file system check if there are any file +system inconsistencies detected in the super block.</P> + +<P>The filefrag program will now display hte shared extent flag, which is +used by file systems such as btrfs.</P> + +<P>If the number of inodes in the file systems is larger than the time +that file sytem was created (as measured by the number of seconds +since January 1, 1970) e2fsck would print a scary (but otherwise +harmless) warning of file system corruption for each inode in the +orphan list. This false positive has been fixed.</P> + +<P>The e4defrag program has been fixed so it will no longer refuse with +filesystem with the 64-bit or the bigalloc feature enabled.</P> + +<P>The logsave progam will print a much less scary message which could +lead users to believe something has gone very wrong with e2fsck exits +with a non-zero exit status (since this is normal after e2fsck has +automatically fixed a file system corruption during a preen +operation). (Addresses Debian Bug: #468821)</P> + +<P>When creating a file system which is larger than 16TB, the +resize_inode option must be disabled -- since the resize_inode simply +doesn't support reserving metadata block numbers which is larger than +32 bits. The mke2fs program does this automatically if the file +system size is determined automatically. It will now also do this if +the file size is specified explicitly.</P> + +<P>Fixed bugs associated with resize2fs and shrinking bigalloc file +systems.</P> + +<P>The e2fsck program will no longer try to add a UUID on a mounted file +system with checksums enabled, since this could leave the file system +checksums broken.</P> + +<P>Tune2fs will allow the removal of an external journal from file system +which is marked as needing the journal replayed when the force ("-f") +option is given twice. (Addresses Debian Bug: #559301)</P> + +<P>Tune2fs will no longer support enabling sparse_super if the meta_bg +file system feature is enabled, since it could result in data loss. +In practice, all modern file systems have sparse_super is enabled, so +it's not worth trying to change how tune2fs handles enabling the +sparse_super feature.</P> + +<P>Fixed support for 1k block file systems with the meta_bg feature.</P> + +<P>When the superblock is corrupt, e2fsck can't figure out the location +of the alternate superblock. Unfortunately, the routine that +calculates the location of the alternate superblock uses 8193 if it +can't figure this out, so the message printed by e2fsck always +suggests using "e2fsck -b 8193". This message has been fixed to +suggest both the superblock location of 8193 and and 32768. +(Addresses Debian Bug: #719185)</P> + +<P>The lookback mount detection code that was introduced in 1.42.9 wasn't +actually compiled in due to an autoconf oops, so it's fixed now in +1.42.10. (Addresses Debian Bug: #497984)</P> + +<P>A bug introduced in 1.42.9 would cause debugfs to print two error +messages if it found an error while parsing a user-supplied block +number. This has been fixed in 1.42.10.</P> + +<P>Update Czech, Dutch, French, German, Polish, Spanish, Sweedish, and +Vietnamese translations. (Addresses Debian Bug: #703048)</P> + +<P>Updated/fixed various man pages. (Addresses Debian Bugs: #719189, +#719184)</P> + +<P>Fixed various Debian Packaging Issues. (Addresses Debian Bug: #718725)</P> + + +<h3>Programmer's Notes</h3> + +<P>Fixed a lot of coverity, sparce gcc -Wall, and clang warnings/nits.</P> + +<P>Allow the location of pkg-config files to be specified independent of +the libdir location via a makefile variable.</P> + +<P>Fixed parse-types.sh not to complain when cross-compiling and the +sizes of types are different between the target architecture and the +architecture of the build system</P> + +<P>Allow the regression test suite to work correctly on systems which do +not have the "truncate" or "mksawp" programs.</P> + +<P>Allow e2fsck to build correctly on systems (such as Android) that do +not have the signal.h file.</P> + +<P>E2fsprogs now has code coverage testing which can be enbled using +"configure --enable-gcov".</P> + +<P>The libe2p.h header file can now be used included by C++ programs.</P> + +<P>The profile/config file used by e2fsck and mke2fs will interpret +numbers with a leading 0 character to mean that they should be +interpreted as an octal integer.</P> + +<P>The extent handling functions in libext2fs have been improved so they +have proper rollback when there is an error splitting an extent. Also +fix a number of bugs when punching holes in files, and fix an +off-by-one bug when inserting an extent into an empty inode.</P> + +<P>The libext2fs library now handles the support of BLOCK_UNINIT by +clearing the portion of block bitmap when it is loaded, instead of +when it is used. This reduces the chances of bugs, and and simplifies +the code. It also means that debugfs will properly show that blocks +in uninitialized block groups as being unused when using the testb +command.</P> + +<P>The e4defrag program will try to use fadvise64 or posix_fadvise64() if +it is present, which allows 64-bit offsets on 32-bit systems.</P> + + <H2><A NAME="1.42.9">E2fsprogs 1.42.9 (December 28, 2013)</A></H2> <P>Mke2fs will detect an attempt to create a file system on a loop diff --git a/htdocs/ext2.html b/htdocs/ext2.html index 846807c84..f5e42b643 100644 --- a/htdocs/ext2.html +++ b/htdocs/ext2.html @@ -28,9 +28,9 @@ <!-- Begin actual content --> <IMG SRC="../images/new.gif" ALIGN=LEFT> -<H2>Release 1.42.9 of e2fsprogs is available!</H2> +<H2>Release 1.42.10 of e2fsprogs is available!</H2> -<P>On December 28, 2013, version 1.42.9 of e2fsprogs was <A +<P>On May 18, 2014, version 1.42.10 of e2fsprogs was <A HREF="http://e2fsprogs.sourceforge.net">announced</A>.</P> <H2>Ext2fs Utilities</H2> diff --git a/htdocs/index.html b/htdocs/index.html index 493ce0861..992885ab4 100644 --- a/htdocs/index.html +++ b/htdocs/index.html @@ -34,14 +34,14 @@ <A HREF="http://www.kernel.org/pub/software/scm/git/docs/gittutorial.html">here</A>.</P> - <IMG SRC="images/new.gif" ALIGN=LEFT><H2>Release 1.42.9 of e2fsprogs is + <IMG SRC="images/new.gif" ALIGN=LEFT><H2>Release 1.42.10 of e2fsprogs is available!</H2> <P>I am happy to announce a new release of the e2fsprogs distribution. - All users of e2fsprogs are urged to upgrade to the 1.42.9 version as + All users of e2fsprogs are urged to upgrade to the 1.42.10 version as soon as possible, which can be - downloaded from <A HREF="http://prdownloads.sourceforge.net/e2fsprogs/e2fsprogs-1.42.9.tar.gz">sourceforge</A> - or <A HREF="http://kernel.org/pub/linux/kernel/people/tytso/e2fsprogs/v1.42.9">kernel.org</A>.</P> + downloaded from <A HREF="http://prdownloads.sourceforge.net/e2fsprogs/e2fsprogs-1.42.10.tar.gz">sourceforge</A> + or <A HREF="http://kernel.org/pub/linux/kernel/people/tytso/e2fsprogs/v1.42.10">kernel.org</A>.</P> <P>This release contains a number of bug fixes and enhancements over the previous releases.
