Also fixed mke2fs -so it allows the creation of a file system on a mounted device with -two -F options, as documented in the man page, instead of three -F -options. - -Fixed a large number of bugs in resize2fs, e2fsck, debugfs, and -libext2fs to correctly handle bigalloc and 64-bit file systems. There -were many corner cases that had not been noticed in previous uses of -these file systems, since they are not as common. Some of the bugs -could cause file system corruption or data loss, so users of 64-bit or -bigalloc file systems are strongly urged to upgrade to e2fsprogs -1.42.9. - -The tune2fs program will now not allow changing the uuid on a mounted -file system which has the uninit_bg feature enabled. This avoids a -nasty race where the kernel and tune2fs are both retrying rewrite the -group descriptors at the same time, with different ideas about what -the UUID should be. - -When e2fsck is rehashing an extent-mapped directory, it's possible -(although very rare) that an extent block will need to be allocated; -fix e2fsck to make sure that the block gets marked as used. - -Mke2fs will now properly set the LARGE_FILE feature when creating a -journal >= 2GB --- which can happen when using 64k block size. - -Fixed debugfs so that its freei command will correctly handle a request -to free a range of consecutive inodes. - -Fixed 2fsck so it will not erroneously complain that an external journal -is invalid if it is exactly 2**32 blocks. - -Fixed e2fsck so it won't try checking for, and adding, a missing -lost+found directory when running in read-only mode. - -Fixed e2image to avoid some buffer overruns which would cause it to when -creating a "standard (non-raw, non-qcow2) image file. Standard -e2image files are actually very rarely used, so we didn't notice when -the changes to enable the qcow2 format broke this e2image mode. - -Fixed mke2fs so that the extended option "-E resize=NNN" will not turn -on the resize_inode feature when the meta_bg feature is set, since -these two features can not be set at the same time. - -Fixed tune2fs so that when it disables the quota feature, it updates all -of the backup superblocks. - -Fixed dumpe2fs that would cause it to abort when run using an image file -when trying to print the journal information (which is not present in -an e2image created image file). - -Fixed a potential integer overflow in e2reefrag. -(Addresses-Debian-Bug: #718205) - -Enhance debugfs so that when copying a sparse file from a native file -system into the file system image using the "write" command, it will -create a sparse file into the destination file system. - -Enhanced debugfs so it can support a command line which is up to 8k -long. - -E2image will refuse (unless the -f option is specified to force the -issue) to create a raw or qcow image using a mounted file system, -unless the -f option is specified to force the issue. - -E2image has been optimized for using it to efficiently copy a file -system by only copying the allocated blocks, by using the options -ra. -New options (-o and -O) have been added so that a source and -destination offset can be given. The -p option will print progress -information so the user will know how far along the copy is going. -And finally, the new option -c is useful for updating a file system on -an SSD, by avoiding unnecessary writes. E2image can also shift a file -system image by doing an in place move. - -Fix a regression introduced in 1.42.8 which would cause e2fsck to -erroneously report uninitialized extents past the EOF (as determined by -i_size) to be invalid. - -Fixed resize2fs so under a corner case when an inode has a complex -extent tree, it will not corrupt an interior node in the extent tree. - -Fixed resize2fs which would sometimes corrupt a file system when -shrinking a file system to a minimum size using resize2fs -M. -(Addresses Debian Bug: #660793) - -Fixed resize2fs so that it will relocate inode table blocks if this -becomes necessary when shrinking the file system. - -Fixed resize2fs and e2fsck so they will not crash when hit a failure -while operating on a file system with the MMP feature enabled. - -Fixed a bug in debugfs which caused it create an invalid inode when -trying to write a zero-length file. - -E2fsck will no longer crash if it tries to delete an invalid -extent-mapped symlink. - -E2fsck will no longer crash if it comes across an directory which is -larger than 2GB (which is not allowed in valid file systems). - -Fixed debugfs's help texts to fully document all options and otherwise -be more helpful. - -Updated/fixed various man pages. (Addresses Debian Bugs: #586218, -#669730, #698076) - -Fixed various Debian Packaging Issues (#698879, #721365) - - -Programmer's Notes ------------------- - -Fix sparse, gcc -Wall and clang nits. - -Update config.{guess,sub} to the latest version - -Fixed various memory and file descriptor leaks on various error paths, -as well as some missing error return checks, which were found using -Coverity. - -Run sparse against source files when building e2fsprogs with 'make -C=1'. If instead C=2, it configures basic ext2 types for bitwise -checking with sparse, which can help find the (many many) spots where -conversion errors are (possibly) happening. - -Allow the regression test to be run in chrooted environments where -/etc/mtab might be missing. - -The ext2fs_punch() function, which was introduced in 1.42, was broken -in many ways, but this was never noticed since it wasn't used for -anything significant. Some of the bugs include failing when trying to -punch a completely sparse file, failing when punching an extent-mapped -inode when the starting block was at the beginning of the inode, and -not being able to punch a single block (where start_blk == end_block). -It also didn't handle being passed an invalid, too-large ending block -number, and didn't handle properly terminate at the right place when -operating on an indirect-mapped inode. - -Fixed some minor typo's in the error catalog for libext2fs. - -Fixed ext2fs_file_set_size2() so that if it truncates an inode by -setting the file size, to zero the rest of the block to the end of the -file, so that if an ext4 FUSE driver tries to extended the file, that -we don't avoid stale data from being returned. - -Fixed ext2fs_bmap() to disallow clients from trying to map or set -logical blocks which are larger than what an extent-mapped or indirect -block-mapped inode can allow. - -If debugfs (or some userspace program using libext2fs) creates a file -which is larger than 2GB, make sure the large_file feature flag gets -set. - -Fix a bug in ext2fs_link() where if there is multiple empty slots in the -directory which are large enough, the directory entry could get -inserted more than once in the directory. - -If quota support is disabled (which is the default), make sure that -all traces of the quota support is removed from usage messages, man -pages, and tune2fs must not be able to enable the quota file system -feature. (Addresses Red Hat Bugzilla: #1010709) - -The ext2fs_file_write() now updates i_size on a successful write, -instead of only updating i_size wen the file is closed via -ext2fs_file_close(). - -Added a shell script, populate-extfs.sh which uses debugfs to populate -an ext2/3/4 file system image from a given directory. It is similar -to the genext2fs program, but it supports ext3 and ext4 file system. - -Add changes to the libext2fs library to support block group -descriptors larger than 64 bytes (for future compatibility). - -Fixed an off-by-one bug in ext2fs_file_set_size2() so that it will not -leave an extra block in the file when truncating the file down to -size. - -The html version info pages are now built using makeinfo --html -instead of the unmaintained and now-obsolete texi2html program. - - -E2fsprogs 1.42.8 (June 20, 2013) -================================ - -As a part of mke2fs's option parsing cleanup, the use of the -R option -will give a warning that it is depreated (it has been so documented -since 2005) and -E should be used instead. - -Mke2fs will not give warnings about the bigalloc and quota options in -quiet mode. - -If an invalid journal size is given to mke2fs, it will now complain -and exit sooner. - -Debugfs was erroneously giving spurious error messages for certain -extent_inode subcommands which take arguments (split_node, -replace_node, and insert_node). This has been fixed. - -Fix the parsing of the 's' (sectors) in parse_num_blocks2, which among -other programs is used by mke2fs. - -Change mke2fs so that it does not set the root directory to the real -uid/gid of the mke2fs process. Add the extended option root_owner to -override this behavior. - -Fix resize2fs when shrinking file systems to make sure that bitmap -blocks aren't left outside the bounds of the shrunken file system. -This could happen with flex_bg file systems that were grown using -the old online resizing algorithm. - -E2fsck will now detect and repair corrupted extent trees which contain -invalid extents at the end of the extent tree leaf block. - -E2fsck will now longer complain about zero length extended attribute -values. - -Fix a regression introduced in e2fsprogs v1.42 which caused e2image -s -to crash. - -Add safety check so tune2fs will not attempt to set the inode size to -be larger than the block size. - -Fix e2fsck so it can check a read-only root file system with an -external journal. (Addresses Debian Bug: #707030 - -Fix off-line resizing of file systems with flex_bg && !resize_inode -(Addresses Debian Bug: #696746) - -Fix e2image with large (> 32-bit) file systems (Addresses Debian Bug: -#703067) - -Enhance chattr to allow clearing the extent flag if the kernel allows -migrating extent based files to use indirect blocks. - -Update German translation. - -Updated/fixed various man pages. (Addresses Debian Bugs: #712429, -#712430, #707609) - -Fixed various Debian Packaging Issues (Addresses Debian Bug #708307) - -Programmer's Notes ------------------- - -Use secure_getenv() in preference to __secure_getenv(). - -Optimize CPU utilization of ext2fs_bg_has_super(). - -Fix ext2fs_llseek() on 32-bit i386 systems to work correctly when -SEEK_CUR is used with large files. - -The ext2fs_read_inode_full() function will no longer use -fs->read_inode() if the caller has requested more than the base 128 -byte inode structure and the inode size is greater than 128 bytes. - -Fix build failure with --enable-jbd-debug. - -Clean up filtering of outputs for the regression tests by using a -common sed script. - -Fix gcc -Wall and clang nits. - - -E2fsprogs 1.42.7 (January 21, 2013) -=================================== - -Add warnings to mke2fs, resize2fs, and tune2fs that the bigalloc and -quota features are still under development. For more information -please see: - * https://ext4.wiki.kernel.org/index.php/Bigalloc - * https://ext4.wiki.kernel.org/index.php/Quota - -Add some new options to filefrag from Lustre's patches to e2fsprogs: - * add -k option to print extents in kB-sized units (like df -k) - * add -b {blocksize} to print extents in blocksize units - * add -e option to print extent format, even when FIBMAP is used - * add -X option to print extents in hexadecimal format - -Fix resize2fs so that it can handle off-line resizes of file systems -with the flex_bg feature but without a resize_inode (or if we run out -of reserved gdt blocks). This also fixes a problem where if the user -creates a filesystem with a restricted number of reserved gdt blocks, -an off-line resize which grows the file system could potentially -result in file system corruption. - -Fix a resize2fs bug which could cause it to corrupt bigalloc file -systems when doing an off-line resize. - -Further optimize resize2fs so it doesn't use quite as much CPU when -resizing very large file systems. - -Fixed 32-bit overflow bugs which could cause resize2fs to fail and -possibly corrupt the file system while resizing 64-bit file systems. - -Fix a bug in mke2fs where parsing "-E resize=NNN" will result in a -mke2fs crash due to a divide-by-zero if the 64bit file system feature -is enabled. - -Add better error checking to mke2fs to check for invalid parameters -when creating bigalloc file system. - -When creating bigalloc filesystems, the -g option to mke2fs will now -specify the number of clusters per block group. - -Add to debugfs the functionality to corrupt a specific file system -block via the "zap_block" command. - -Add to debugfs the functionality to print out a hex dump of a block in -the file system via the "block_dump" command. - -Add to debugfs the functionality to manipulate the extent tree -directly via the "extent_open" command. - -Fixed debugfs's mknod command so that it updates the block group -statistics. - -Fix e2fsck so it can detect and fix inconsistencies in the interior -nodes of an inode's extent tree. - -Fix a potential memory corruption failure in e2fsck's error path if -the call to ext2fs_open2() fails. - -Fix e2fsck if its logging function is enabled in e2fsck.conf, and the -resulting file name for the log file is longer than 100 bytes, that it -properly handles this situation instead of crashing. - -E2fsck will now report the amount of memory that it attempted to -allocate when a memory allocation request fails, to make it easier to -track down the problem. - -Fix mke2fs's handling of the mmp_update_interval option. (Addresses -Lustre Bug: LU-1888) - -E2image can now include all data blocks in the e2image output file -when the user specifies the -a option. - -If e2fsprogs is compiled without --enable-quota, make sure that -tune2fs can not turn on the feature for new-style quota support, since -afterwards, none of the e2fsprogs tools will be willing to touch that -file system. - -Optimize e2fsck's so that it uses much less CPU for large file -systems. This can result in significant speedups, especially on -CPU-constrained systems. This was primarily done by optimizing -libext2fs's bitmap functions. (Addresses Google Bug: #7534813) - -Fix debugfs's htree command so that all its messages are sent through -the pager. - -Fixed debugfs's "dump_file" and "cat" functions work correctly -on file systems whose block size is greater than 8k. - -Fix e2freefrag so it works on 64-bit file systems, and so it uses much -less memory. (Addresses Google Bug: 7269948) - -Update the spd_readdir.c file in the contrib directory to include some -additions which were made in 2008 that didn't get folded into the -version which we checked into the e2fsprogs source tree. These -enhancements include thread safety, support for readdir64_r(), and -safe_getenv() support in case spd_readdir.so is used for setuid binaries. - -Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese -translations - -Add a command to debugfs to create symlinks. - -Document the bigalloc feature in the mke2fs man page. (Addresses -Debian Bug: #669730) - - -Programmer's Notes ------------------- - -Fix gcc -Wall nits. - -Fix a spelling typo in the libext2fs texinfo documentation. - -Change the output from "make check" so that tools such as emacs's "M-x -compile" does not mistake the output as containing a compiler error. - -Export two new functions from libext2fs: ext2fs_extent_node_split() -and ext2fs_extent_goto2(). - -The ext2fs_extents_fix_parents() was fixed so it does not modify the -location of the extent handle if its current location is at an -interior node, rather than a leaf node of an inode's extent tree. - -Add a regression test to assure that e2fsck can correctly fix an -inconsistent interior node in an inode's extent tree. - -The ext2fs_{mark,unmark,test}_block_bitmap_range2() functions now -correctly support bigalloc file systems which use store block usage -information in units of clusters. - -Fixed the help text in the configure script for --enable-quota. - -The m68k-specific bitops code has been removed since they were -incorrectly treating bit numbers with the high bit set as signed -integers. Furthermore, modern compilers do a good enough job -optimizing the generic code there is no point in having the m68k -specific asm statements. - -Fixed how we link the test programs so they always use the static -libraries, so that we test using the libraries which we have just -built. - -Update config.guess and config.sub to the latest versions from the GNU -project. - -Fixed the com_err.texinfo file so that it can produce a valid -postscript/pdf printed output. - -Add a regression test which checks debugfs's ability to create -symlinks, named FIFO's, and device nodes. - -Add a function ext2fs_symlink(), which creates symlinks to the -libext2fs library. - -Add debugging code so we can test old kernel interfaces for online -resize to resize2fs. This backwards compatibility checking is keyed -off of the RESIZE2FS_KERNEL_VERSION, which is designed to allow us to -test the functionality of the kernel's older resize ioctls without -needing to install an old version of resize2fs, and to also test a -modern resize2fs's ability to work with older kernels without having -to install an older version of the kernel. - - -E2fsprogs 1.42.6 (September 21, 2012) -===================================== - -When mke2fs creates file systems with lazy itable initialization, the -progress updates for writing the inode table happens so quickly that -on a serial console, the time to write the progress updates can be the -bottleneck. So mke2fs will now only update its progress indicators -once a second. - -Resize2fs will skip initializing the inode tables if the kernel -supports lazy_itable_init, which speeds up growing off-line growth of -uninit_bg file systems significantly. Resize2fs will now also -correctly set the itable_unused field in the block group descriptor to -speed up the first e2fsck after the file system is grown. - -Resize2fs has been fixed so that on-line resizing of meta_bg file -systems work correctly. This is needed to grow file system which are -larger than 16T. - -Resize2fs will now correctly handle resizing file systems to 16TB on -32-bit file systems when "16TB" is specified on the command line. - -Fix mke2fs so that it will be careful to set the reserved blocks ratio -larger than 50%; this can happen when creating small file systems and -when the last block group is dropped because there are not enough -blocks to support the metadata blocks in the last block group. - -Fixed spelling mistake in debugfs's help message. - -Fixed a potential seg fault in e2fsck when there is an I/O error while -reading the superblock. - -Fixed various Debian Packaging Issues (Addresses Debian Bug #677497) - -Updated/fixed various man pages. (Addresses Sourceforge Bug: -#3559210) - -Programmer's Notes ------------------- - -The configure option --enable-relative-symlink was broken so that it -needed to be --enable-symlink-relative-symlinks. We will support both -for at least two years, but then the worng configure option will be -removed. - -Fixed a regression introduced in 1.42.5 so the link order for -e2fsprogs' libraries will be correct for both static and shared -linking. (Addresses Sourceforge Bug: #3554345) - -Add support for e2fsprogs to be compiled using clang/LLVM. - -Fix portability problems on non-Linux systems: avoid compile failures -on systems that don't have malloc.h - -Fix f_mmp regression test suite so that debugfs gets killed if the -test is interrupted. - - - -E2fsprogs 1.42.5 (July 29, 2012) -================================ - -Fixed a bug with mke2fs where if there is only 8 inodes per block -group, the calculation of the number of uninitialized inodes in the -first block group would go negative. This resulted in "mke2fs -N 256 --t ext4 /tmp/foo.img 256m" trying to write so many blocks that /tmp -would run out of space. (Addresses Sourceforge Bug: #3528892) - -Fixed a bug in how e2fsck would uniquify directory entry names. -(AddressesSourceforge Bug: #3540545) - -Previously, e2fsck would only allow a mounted file system to be -checked if it was the root file system and it was mounted read-only. -Now it will allow any file system mounted read-only to be checked if -the -f option is specified. This makes it easier to test how e2fsck -handles checking file systems which are mounted without having to test -on the root file system. - -Fixed a problem if e2fsck where if the root file system is mounted -read-only, e2fsck would not clear an error indication in the journal -superblock. Combined with a kernel bug, this would cause the e2fsck -to check the file system after every single boot. - -The e4defrag program can now handle device symlinks, such as -/dev/mapper/testvg-testlv, instead of insisting on a less -human-friendly name such as /dev/dm-2. (Addresses Red Hat Bugzilla: -#707209) - -Fixed filefrag so it will not crash with a segfault on files from a -virtual file system such as /proc. (e.g., "filefrag -/proc/partitions") - -Fixed filefrag so that it correctly reports the number of extents. -(Addresses Red Hat Bugzilla: #840848) - -Fixed a file descriptor leak in logsave which could cause it to hang. -(Addresses Debian Bug: #682592) - -Fixed e2fsck so that the file system is marked as containing an error -if the user chooses not to fix the quota usage information. - -Fixed tune2fs so that it correctly removes the quota feature when the -last quota inode is removed. - -Fix tune2fs so that after removing a quota inode, the block bitmap is -updated; otherwise, e2fsck would complain after running 'tune2fs -O -^quota '. - -Fix tune2fs so that when converting a file system from using legacy -quota files to the new quota file system feature with hidden quota -files, the accounting for these files is handled correctly so that -e2fsck doesn't complain. - -Improved e2fsck's verbose reporting statistics, and allow the more -verbose reporting to be enabled via /etc/e2fsck.conf. - -Fixed various Debian Packaging Issues (Addresses Debian Bug #678395) - -Updated/fixed various man pages. (Addresses Debian Bugs: #680114) - - -Programmer's Notes ------------------- - -Fixed portability problems on other operating systems (e.g., Hurd and -FreeBsd) caused by the attempted inclusion of . - -Make sure that shared libraries link with the shared libraries built -in the build tree, instead of the system provided libraries. -Previously, libraries and executables were linked with the system -libraries if present, and possibly using static archives instead of -shared libraries. This was also problematic since if libext2fs.so is -linked with a static libcom_err.a from system, the build system would -attempt to link without -lpthread. (Addresses Sourceforge Bug: -#3542572) - - -E2fsprogs 1.42.4 (June 12, 2012) -================================ - -Fixed more 64-bit block number bugs (which could end up corrupting -file systems!) in e2fsck, debugfs, and libext2fs. - -Fixed e2fsck's handling of the journal's s_errno field. E2fsck was -not properly propagating the journal's s_errno field to the superblock -field; it was not checking this field if the journal had already been -replayed, and if the journal *was* being replayed, the "error bit" -wasn't getting flushed out to disk. - -Fixed a false positive complaint by e2fsck if all of the extents in -the last extent tree block are uninitalized and located after the end -of the file as defined by i_size. - -The dumpe2fs will now display the journal's s_errno field if it is -non-zero, and it will also display the journal's 64-bit feature flag -if present. - -Fix e2fsck so that it always opens the device file in exclusive mode -when it might need to modify the file system, and never if the -n -option is specified. (Previously, there were a few corner cases where -it might get things wrong in either direction.) - -E2fsck now correctly truncates or deallocates extent-mapped inodes on -the orphan list. The root cause was a bug in libext2fs's block -iterator which could end up skipping an extent when the last block in -an extent is removed, causing the current extent to be removed from -the extent tree. - -E2fsck now correctly sets the global free block and inode counts when -truncating or removing inodes on the orphan list in preen mode. -Previously, it would leave these values would be set incorrectly, -which is largely a cosmetic issue since the kernel no longer pays -attention to those fields, but it can cause spurious complaints in -subsequent e2fsck runs. - -Fix i_blocks accounting when the libext2fs library needs to add or -remove an extent tree block on bigalloc file systems. - -The lsattr and chattr programs now support the No_COW flag for the -benefit of btrfs. - -Debugfs now interprets date strings of the form @ddd as ddd seconds -after the beginning of the epoch. This is handy when setting an inode -number into the d_time field when debugging orphan list handling. - -Fix a precedence bug with built-in quota support which might result in -e2fsck paying attention to the quota inode field even if the built-in -quota feature flag is not set. Fortunately, in practice that -superblock field should be zero for non-built-in quota file systems, -so it's unlikely this bug would have caused problems. - -Updated/fixed various man pages. (Addresses Debian Bugs: #674453, -#674694) - -Programmer's Notes ------------------- - -The regression test suite can now run the integration tests in the -tests directory in parallel, via "make -jN check". - -Add new test, f_zero_extent_length which tests e2fsck's handling of -the case where all of the extents in the last extent tree block are -uninitialized extents after i_size. - -Add a new test, f_jnl_errno, which checks handling of an error -indication set in the journal superblock. - -Fix the test f_jnl_64bit so that it properly checks e2fsck's handling -of a 64-bit journal. - -Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which -tests e2fsck's handling of orphan inodes in preen mode, and truncation -of extent inodes on the orphan list. - -Fixed more OS X portability issues. - - -E2fsprogs 1.42.3 (May 14, 2012) -=============================== - -Fix a bug in the Unix I/O manager which could cause corruption of file -systems with more than 16TB when e2fsprogs is compiled in 32-bit mode -(i.e., when unsigned long is 32-bits). Also fix a bug which caused -dumpe2fs to incorrectly display block numbers > 32-bits. - -Improve the support for integrated quota files (where quota is a first -class supported feature using hidden files in the ext4 file system). -Previously the quota file was getting rewritten even when it was not -necessary, and e2fsck would erroneously try to hide quota files which -were already hidden. - -Quiet complaints in e2fsck when the total free blocks or inodes are -incorrect in the superblock after an system crash, since we don't -update nor depend on the superblock summaries at each commit boundary. - -Fixed a regression introduced in 1.42.2 which would cause applications -outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so -would were still using the legacy 32-bit bitmaps) to crash. This was -due to missing 32-bit compat code in side the function -ext2fs_find_first_zero_generic_bmap(). (Addresses Red Hat Bugzilla: -#808421) - -Fix a bug which would cause mke2fs to fail creating the journal if -/etc/mtab and /proc/mounts are missing. (Addresses Sourceforge Bug: -#3509398) - -Updated/fixed various man pages. - -Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese -translations - -Fixed various Debian Packaging issues. - - -Programmer's Notes ------------------- - -Change the nonsensically wrong types in the function signature of the -inline function ext2fs_find_first_zero_block_bitmap2(). This was -caused by a cut and paste error; fortunately no code in e2fsprogs used -this inline function, and there are any users of this functions -outside of e2fsprogs. - -Add support for systems which have valloc(), but which do have -posix_memalign() nor memalign() (such as MacOS 10.5). - -Refactor and clean up the allocation of aligned buffers for Direct I/O -support. Previously some allocations were requesting a greater -alignment factor that what was strictly necessary. Also optimize -reading and writing bitmaps using Direct I/O when the size of the -bitmap did not fully cover the file system blocksize. - -Reserve the codepoints for the INCOMPAT features LARGEDATA and -INLINEDATA. - -Improved the regression test suite by adding some new integration -tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk -jbd2 format, as well as f_eofblocks which tests the new handling of -uninitialized and initialized blocks beyond i_size. Also add a new -unit test which verifies 32-bit bitmaps support and the new -find_first_zero primitives. - -Add a few dependencies to fix parallel (make -j) builds. - -Removed bash'isms which were breaking the regression test suite on -systems where /bin/sh is not bash. - -The config.guess and config.sub have been updated to the 2012-02-10 -version. - -Fix a portability problem caused by assuming the present of mntent.h -means that setmntent() exists. Instead, explicitly test for this in -the configure script. - -If the sys/signal.h header file does not exist, don't try to include -it, since it's not available on all systems. - -Add support for systems that do not support getpwuid_r() - -The configure script now supports a new option, ---enable-relative-symlinks, which will install relative symlinks for -the ELF shared library files. (Addresses Sourceforge Bug: #3520767). - -When building BSD shared libraries make sure the LDFLAGS variable is -passed to the linker. Fixing this allows, for example, e2fsprogs to -be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug: -#3517272) - -Fix gcc -Wall nitpicks - - -E2fsprogs 1.42.2 (March 27, 2012) -================================= - -The resize2fs program uses much less CPU and is much faster for very -large file systems. (Addresses Debian Bug: #663237) - -The seti and freei commands in debugfs can now take an optional length -argument to set and clear a contiguous range of inodes. - -E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we -plan to remove support for it from the kernel file system driver. It -really wasn't very useful and was causing more problems than it -solves. Since e2fsck will complain if inodes that should have -EOFBLOCKS_FL do not have the flag set, we are going to remove this -check from e2fsprogs first, and then only remove the flag from the -kernel much later. - -The mke2fs program can now use direct I/O via "mke2fs -D". This will -slow down the mke2fs, but it makes it more polite on a loaded server -by limiting the amount of memory that gets dirtied by mke2fs when it -is using buffered I/O. - -E2fsck was needlessly closing and re-opening the file system as a side -effect of adding Multiple Mount Protection (MMP). This isn't -necessary for non-MMP file systems, so drop it. - -Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we -can more easily diagnose memory allocation failures caused by -insufficient memory. E2fsck will now abort if there are memory -allocation failures when the file system is initially opened and -during the block group descriptor checks. (Addresses Google Bug: -#6208183) - -If there are incorrect block group checks, e2fsck will now report the -incorrect and corrected checksum values. - -The e2fsck progam can now write log files containing the details of -the problems that were found and fixed directly, via configuration -parameters in /etc/e2fsck.conf. - -Added the ability to limit the number of messages reported by e2fsck -for a given problem type. This avoids a potential bottleneck if there -is a serial console which can cause a boot sequence to take a long -time if e2fsck needs to report many, many file system errors. - -The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause -them to use much less memory for large file systems. - -The dumpe2fs program will now print the expected block group checksum -if it is incorrect. This helps to diagnose problems caused by -incorrect block group checksums. - -E2fsck now checks for extents with a zero length, since the kernel -will oops if it comes accross such a corrupted data structure. (See -https://bugzilla.kernel.org/show_bug.cgi?id=42859) - -E2fsck has a number of bugs relating to discard that have been fixed. -(1) Fixed a bug which could cause e2fsck to discard portions of the -inode table which were actually in use. (2) E2fsck will now avoid -using discard if the block device doesn't zero data on discard, since -otherwise this could cause problems if the file system gets corrupted -in the future. (3) E2fsck will now avoid using discard when it is run -in read-only mode. (4) Fixed a bug which caused e2fsck to not issue -discards in the last block group. - -E2fsck's CPU utilization in pass 5 has been optimized, which will -speed up e2fsck slightly. - -E2image will now skip copying uninitialized bitmap and inode table -blocks. - -Fixed mke2fs -S so it does not corrupt the first block group's -information. - -E2fsck will now check the new sysfs interface to determine if we are -using the battery or AC mains. (Addresses SourceForge Bug: #3439277) - -Updated/fixed various man pages. (Addresses Debian Bug: #665427) - -Fixed various Debian Packaging issues. (Addresses Debian Bug: #665885) - -Programmer's Notes ------------------- - -Fixed various portability issues for non-Linux systems, particularly -MacOS X, as well as Linux systems running with the just-released glibc -2.15. - -Fix file descriptor leak in ext2fs_close() if the file system with -uninit_bg is opened read/only with a backup superblock. (Addresses -SourceForge Bug: #3444351) - -Fixed an invalid return in a non-void function in the quota code. -(Addresses SourceForge Bug: #3468423) - -Fixed the debian rules file so that the calls to dpkg-buildflags works -when the shell is dash. - -The debian package build now uses V=1 so that there is more -information about potential build failures in debian buildd logs. - -If the uninit flags get cleared by functions such as -ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the -superblock is marked dirty and the block group descriptor checksum is -updated if necessary. - -The debian rules file will now try to load debian/rules.custom of it -exists. This flie can skip various builds for speed reasons if there -is no need for the e2fsck-static or udeb packages. Available -customizations in the rules file includes SKIP_STATIC=yes, -SKIP_BF=yes, and SKIP_DIETLIBC=yes. - -In addition, if the file misc/mke2fs.conf.custom.in exists in the -source tree, it will be used instead of the standard misc.conf file in -the upstream sources. This makes it easier for Debian-derived systems -to distribute a custom mke2fs.conf file without having to worry about -merge issues if future versions of e2fsprogs makes changes in the -upstream default version of mke2fs.conf. - - -E2fsprogs 1.42.1 (February 17, 2012) -=================================== - -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. - - -E2fsprogs 1.42 (November 29, 2011) -================================== - -This release of e2fsprogs has support for file systems > 16TB. Online -resize requires kernel support which will hopefully be in Linux -version 3.2. Offline support is not yet available for > 16TB file -systems, but will be coming. - -This release of e2fsprogs has support for clustered allocation. This -reduces the number of block (now cluster) bitmaps by allocating and -deallocating space in contiguous power-of-2 collections of blocks, -which are called clustered. This is a file system level feature, -called 'bigalloc', which must be enabled when the file system is -initially formatted. It is not backwards compatible with older -kernels. - -Added support for the Multi-Mount Protection (MMP) feature. - -E2fsck more efficiently uses scratch files for really big file -systems. (This is a feature that has to be turned on explicitly; see -[scratch_files] in the e2fsck.conf man page.) - -Fix a bug in e2fsck where if the free blocks and inodes counts are -incorrect, e2fsck would fix them without printing an error message. -This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without -any explanation of what was fixed. - -E2fsck will no longer attempt to clone an extended attribute block in -pass1b handling if the file system does not support extended -attributes. - -E2fsck will be more careful accidentally asking the user to continue -if the file system is mounted, so that an escape sequence won't cause -a false positive. (Addresses Debian Bug: #619859) - -E2fsck now uses less cpu time in pass 5 when large portions of the -bitmaps are uninitialized. - -E2fsck will no longer segault when a corrupted file system has a bad -extent, and removing it leads to a block needing to be deallocated. -(Addresses SourceForge Bug: #2971800) - -E2fsck will catch termination signals (segfaults, bus errors, sigfpe) -and print debugging information to make it easier to find potential -problems. - -E2fsck will check to see if the bad block inode looks insane, and will -skip trying to use if it certain fields which should be zero look -non-zero. This is to avoid a corrupted bad block inode causing e2fsck -to get confused and do more harm than good. - -If e2fsck modifies certain superblock fields which the kernel doesn't -look at, it will now mark the superblock as dirty without marking the -file system as changed. This avoids signalling the init scripts that -a reboot is necessary, since the kernel isn't going to look at those -fields, so it won't care if they have been changed. - -Fixed a bug in the libext2fs library (in the binary search routine of -the icount abstraction) that could (very, very rarely) cause e2fsck to -die in the middle of pass 1 or pass 2 processing. - -E2fsck will not try to do a discard operation if the -n option was -specified on the command line. - -E2fsck now supports an extended "discard" option which will cause -e2fsck to attempt discard all unused blocks after a full, successful -file system check. - -E2fsck will check for the bad block inode to make sure it looks sane -before trusting it, to avoid causing more harm than good to the file -system. - -E2fsck now returns additional status bits in its exit code if it -aborts early in the e2fsck run. - -E2fsck now correctly calculates the maximum file size in the case of -the huge_file file system feature enabled without extents. - -The mke2fs and e2fsck programs now tries to use the punch hole command -as a "discard" when operating on normal files. - -The e2image program now supports the qcow2 format, which is a more -efficient way of capturing file system dumps. - -Mke2fs now supports the [devices] stanza in mke2fs.conf which allows -per-device defaults to be specified in the configuration file. - -Mke2fs now supports the reserved_ratio relation in the [defaults] and -[fs_types] section in mke2fs.conf. - -Mke2fs now creates extent-mapped directories for the root and -lost+found directories. - -Mke2fs will skip zero'ing the journal if the extended option -"lazy_journal_init" is specified. This can save a lot of time, but it -does add a small amount of risk if the system crashes before the -journal is overwritten entirely once. It is epsecially useful for -testing. - -Mke2fs will now create file systems that enable user namespace -extended attributes and with time- and mount count-based file -system checks disabled. - -Mke2fs will not set a stride or strip size of one block based on block -device attributes obtained from sysfs. - -Mke2fs now displays a progress report during the discard process. - -Mke2fs now handles extreme file system parameters correctly which -previously caused the inodes per group to drop below 8, leading to a -segfault. (The inodes per group must be a multiple of 8, but the code -didn't correctly deal with an inodes per group count less than 8.) - -Mke2fs and tune2fs previously would give an error if the user tried -setting the stride and stripe-width parameters to zero; but this is -necessary to disable the stride and stripe-width settings. So allow -setting these superblock fields to zero. (Addresses Google Bug: -#4988557) - -Mke2fs now gives a warning if the auto-detected block size exceeds the -system's page size. - -If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which -is the default), mke2fs will now set the s_max_mnt_count superblock -field to -1, instead of 0. Kernels older then 3.0 will print a -spurious message on each mount then they see a s_max_mnt_count set to -0, which will annoy users. (Addresses Debian Bug: #632637) - -The default mke2fs.conf now has entries for "big" and "huge", which -are needed for very big file systems. - -The resize2fs program now has support for a new online resize ioctl -that can support file systems > 16TB, once it arrives in v3.x kernels. - -Fixed bug which caused resize2fs to fail when shrinking an empty file -system down to its minimal size. (Addresses Sourceforge Bug #3404051) - -Fixed tune2fs's mount options parsing. (Addresses Debian Bug: #641667) - -Allow tune2fs to remove external journals if the device can not be -found. - -Debugfs's icheck will now correctly find inodes which use the -searched-for block as an extended attribute block. - -Debugfs now has a new "punch" command which remove blocks from the -middle of an inode. - -Debugfs now has a new "e2freefrag" command which analyzes the free -space fragmentation of the file system, using the same code as the -e2freefrag program. - -Debugfs now has a "filefrag" command which displays information about -a file's fragmentation. - -Add support to build a metadata-only, read-only, stripped-down version -of debugfs called rdebugfs. - -Fixed a potential stack overrun bug in debugfs. - -The badblocks program now correctly recovers from I/O errors when -direct I/O is being used. The badblocks command now also supports a --B option which forces the use of buffered I/O, and the -v option will -provide a more detailed breakdown of read, write, and failed -comparison errors. - -Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl. - -Added support for journals larger than 2GB. - -Support using both hard links and symlinks when installing e2fsprogs. - -Add overflow checking to tune2fs -i's fsck interval, which must fit in -a 32-bit field. - -The debugfs command now has a new 'blocks' command which prints out -data blocks of a particular inode in a format which is useful for -scripting. - -Filefrag will report 0 extents correctly in verbose mode. (Addresses -RedHat Bugzilla: #653234) - -Filefrag has been fixed so its -v report prints the correct expected -block number (previously there had been an off-by-one error). In -addition, it will now display the number of contiguous extents when -v -is not specified. This makes it consistent with the number of extents -printed when the -v option was specified. In addition, the number of -contiguous extents is far more interesting/useful than the number of -physical extents for very large files.
