| E2fsprogs 1.42.13 (May 17, 2015) |
| ================================ |
| |
| Fixed a potential buffer overflow while closing a file system in |
| libext2fs. (CVE-2015-1572, Addresses Debian Bug: #778948) |
| |
| Fixed a bug which could cause e2fsck to corrupt Hurd file systems. |
| (Addresses Debian Bug: #760275) |
| |
| Fixed a deadlock which occurs when using systemd and e2fsck.conf's |
| logging feature. (Addresses Debian Bug: #775234) |
| |
| Fixed a bug which could cause programs using libext2's inode table |
| scanning functions from crashing on certain corrupted file systems. |
| (Addresses Debian Bug: #773795) |
| |
| Fixed dumpe2fs so it won't crash if the user doesn't specify a block |
| device (file system). (Addresses Debian Bug: #764293) |
| |
| Fixed e2fsck so if it notices unexpected HTREE blocks in pass 2, it |
| will report the correct directory inode containing the inconsistency. |
| |
| If e2fsck fails to grow the dir_info structure due realloc(3) not |
| having enough memory, it will now fail with explanatory message |
| instead of staggering on failing with a confusing internal error |
| messages. |
| |
| The tune2fs program will zero out the superblock journal backup |
| information when removing a journal from a file system. |
| |
| The mke2fs program now enables the large_file feature by default. |
| |

| and millions of bad blocks. |
| |
| Fixed some use-after-free bug in resize2fs and e2fsck. |
| |
| Fixed a memory leak in tune2fs. |
| |
| Fixed some bigendian bugs that had crept into both indirect and extent |
| handling inside libext2fs. |
| |
| Updated/fixed various man pages. |
| |
| Update Esperanto, German, and Spanish translations. Added Danish |
| translation. |
| |
| Programmer's Notes |
| ------------------ |
| |
| Fixed coverity, sparse, gcc -Wall, and clang warnings/nits. |
| |
| Clean up some build system problems (build failures with various |
| configure options, fix Posix portability issues, etc.) |
| |
| The functions ext2fs_inode_alloc_stats[2]() and |
| ext2fs_block_alloc_stats[2]() now check the inode and block numbers |
| passed to them, to avoid crashes caused by buggy callers. |
| |
| The libext2fs directory iterator will now check for an invalid |
| directory entry length instead of possibly walking off the end of the |
| directory buffer. |
| |
| |
| E2fsprogs 1.42.12 (August 25, 2014) |
| =================================== |
| |
| Fix various e2fsck bugs when trying to repair bigalloc file systems. |
| |
| E2fsck can now repair a file system with an overly large |
| s_first_meta_bg field, which had previously caused all e2fsprogs |
| programs to crash when trying to open such a file system. |
| |
| Fix e2fsck so that it can correctly fix a number of rare file system |
| corruptions that were discovered when using a file system fuzzer. |
| |
| Fix e2fsck so it does not try to write back block group descriptors if |
| they have not been modified. |
| |
| Mke2fs program will now place metadata blocks in the last flex_bg so |
| they are contiguous. This reduces free space fragmentation in a |
| freshly created file system, as well as allowing mke2fs commands which |
| request extremely large flex_bg size to succeed. |
| |
| Mke2fs now creates hugefiles more efficiently (with fewer extent tree |
| blocks). |
| |
| Fix a 32/64-bit overflow bug that could cause resize2fs to loop |
| forever. (Addresses-Launchpad-Bug: #1321958) |
| |
| The resize2fs program will now use much less memory when resizing very |
| large file systems. |
| |
| Fix a bug which could cause resize2fs to get confused and produce a |
| corrupted file system when shrinking a file system that had been |
| previously expanded and converted to use the meta_bg file system |
| format, but which no longer needs to use the meta_bg file system |
| format any longer. This typically happened with large (> 16TB) file |
| systems. (Addresses Debian Bug: #756922) |
| |
| The e4defrag program will now defrag backwards-allocated files. |
| |
| Fix tune2fs updating UUID's when manipulating file systems with |
| external journals (both the file system and journal UUID). |
| |
| Fix tune2fs so it can remove an external journal for file systems with |
| a 1k block size. |
| |
| Add a new debugfs command, "inode_dump", which prints the inode in hex |
| and ASCII format. |
| |
| The debugfs's "set_inode_field" will now automatically allocate blocks |
| for indirect blocks and extent tree blocks. |
| |
| Fix debugfs's "set_inode_field" so can properly handle |
| "block[IND|DIND|TIND]". |
| |
| The debugfs "rdump" command will now take multiple source arguments. |
| |
| Fixed a double close(2) bug in "rdump" and "rdump -p". |
| |
| Fix debugfs's argument parsing for the freefrag command. |
| |
| Fix filefrag to properly handle using the FIBMAP ioctl (with -B). |
| (Addresses Launchpad Bug: #1356496) |
| |
| Clarified messages that were confusing users in debugfs, e2fsck, |
| mke2fs, and resize2fs (Addresses Debian Bugs: #758029, #757543, |
| #757544) |
| |
| Dumpe2fs will now complain if extra arguments are given to it. |
| (Addresses Debian Bug: #758074) |
| |
| Updated/fixed various man pages. (Addresses-Debian-Bug: #726760) |
| |
| Update Czech, Dutch, French, Polish, Spanish, Swedish, Ukrainian, and |
| Vietnamese translations. |
| |
| Programmer's Notes |
| ------------------ |
| |
| The Unix I/O layer will now use pread[64]/pwrite[64] to reduce the |
| number of system calls issued. |
| |
| Fixed profiled build. |
| |
| The libext2fs library will now more efficiently split an extent tree |
| index block when appending to an end of a file. |
| |
| Fixed free block accounting for 64-bit file systems. |
| |
| Add a new function ext2s_inode_size_set() which takes care of all of |
| the required feature flag modifications. |
| |
| The regression tests no longer require the presence of the md5sum |
| program. |
| |
| Fix build failure on MIPS platforms on Debian (Addresses Debian Bug: |
| #754605) |
| |
| Fix various Coverity warnings (#1225003, #1229243, #1252003) |
| |
| |
| E2fsprogs 1.42.11 (July 9, 2014) |
| ================================ |
| |
| Add support so that mke2fs can create hugefiles so that they are |
| aligned relative to the beginning of the disk, instead of relative to |
| the beginning of the partition, using the mke2fs.conf configuration |
| parameter "hugefiles_align_disk". |
| |
| Fix a bug which causes e2fsck to abort a journal replay on a file |
| system with bigalloc enabled. (Addresses Debian Bug: #744953) |
| |
| Add sanity checks so that mke2fs will refuse insanely large flex_bg |
| counts specified by the -G option. Insanely large flex_bg sizes can |
| result in a file system which can't be unmounted, or with extremely |
| pessimal metadata layouts. |
| |
| The mke2fs program will provide a better metadata layout for |
| moderately large (but believable) flex_bg counts, such as 133,072. |
| |
| The mke2fs program will also check the kernel version number to |
| determine whether the lazy_itable_init option is supported, so that |
| lazy inode table initialization can be used even if the ext4 is |
| compiled as a module which isn't loaded at the time that mke2fs is |
| run. |
| |
| Add description of ext4's mount options to the ext4 section 5 man |
| page. |
| |
| Improve the chattr man page and clean up the chattr usage message. |
| |
| E2fsck will now automatically fix a last mount time or last write time |
| which is in the future in preen mode, instead of aborting the fsck |
| check. |
| |
| Mke2fs will now check the file system revision number requested by the |
| command line, and reject it if it is too large. A file system with an |
| unsupported revision number will not be accepted by any of the other |
| file system tools, and this command line option is rarely used, so |
| let's try to help the user not shoot their own foot off. |
| |
| The debugfs program can now set the error count and associated |
| first_error and last_error fields in the superblock using the |
| set_super_value command. |
| |
| Resize2fs will not try to calculate the minimum size of a file system |
| if it contains errors. Otherwise a very badly corrupted file system |
| image can cause the minimum size calculation to loop forever. Since |
| resize2fs will not allow a file system marked as containing errors to |
| be resized. It's pointless to calculate the minimum size, so just |
| skip it. |
| |
| Fixed a typo in one of mke2fs's error message. |
| |
| If filefrag runs into an error, it will continue processing the rest |
| of the files specified on the command line, but then exit with an |
| error code. |
| |
| Filefrag now prints some additional new flags (such as |
| FIEMAP_EXTENT_ENCODED), and print unknown flags as hex values. |
| |
| Fixed support in filefrag for files with > 2**32 blocks on 32-bit |
| platforms. |
| |
| Fixed a file descriptor leak in debugfs when copying files. |
| |
| Fixed a regression introduced in 1.42.10 which caused mke2fs to fail |
| to create file systems larger than 2GB on 32-bit platforms. |
| (Addresses Red Hat Bugzilla: #1099892, Debian Bug: #752107) |
| |
| Add Esperanto and Ukrainian translations, and update Czech, Dutch, |
| French, German, Italian, Polish, Swedish, and Vietnamese |
| translations. |
| |
| Fixed various compiler warnings. |
| |
| |
| Programmer's Notes |
| ------------------ |
| |
| The gcc "-checker" option has been long deprecated, so remove support |
| from e2fsprogs. It was causing a few people to be confused when they |
| tried enabling the configure option. |
| |
| Update to the latest version of the config.status and config.rpath |
| files, as well as newer versions of the autoconf files in aclocal.m4. |
| Also, move the e2fsprogs-specific macros to acinclude.m4, which allows |
| people who want to use autoreconf to do so. |
| |
| Make the use of strptime() function in debugfs to be more portable to |
| fix regression test failures for FreeBSD and MacOS. |
| |
| A few miscellaneous changes designed to make life easier for |
| translators. |
| |
| Fix the f_quota test and some Makefile dependencies if quota support |
| is not enabled. |
| |
| Fix cross-compilation support, which got broken in 1.42.10. |
| (Addresses Debian Bug: #753375) |
| |
| Delete lib/ext2_types.h on a make clean, and build it as necessary. |
| |
| Add a debug program used for libext2fs unit tests. |
| |
| Clean up the tests so that it avoids using GNU-specific behaviour in |
| mktemp. Make sure the temporary files are cleaned up if the tests are |
| interrupted. |
| |
| Add a new ext2fs_close_free() helper function which automatically |
| takes care of freeing the ext2_filsys structure even if ext2fs_close() |
| returns an error. |
| |
| |
| E2fsprogs 1.42.10 (May 18, 2014) |
| ================================ |
| |
| Mke2fs now creates file systems in regular files (which is very often |
| used when maintaining virtual machine images) without requiring the |
| user to use the force option. 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. |
| |
| 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. |
| |
| 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. |
| |
| Mke2fs now uses much less CPU when allocating the blocks used for very |
| large file systems. |
| |
| 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) |
| |
| Previously, e2fsck had a number of very serious bugs when checking a |
| file system which 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. |
| |
| 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. |
| |
| 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. |
| |
| E2fsck will now force a full file system check if there are any file |
| system inconsistencies detected in the super block. |
| |
| The filefrag program will now display the shared extent flag, which is |
| used by file systems such as btrfs. |
| |
| If the number of inodes in the file systems is larger than the time |
| that file system 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. |
| |
| The e4defrag program has been fixed so it will no longer refuse with |
| filesystem with the 64-bit or the bigalloc feature enabled. |
| |
| The logsave program 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) |
| |
| 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. |
| |
| Fixed bugs associated with resize2fs and shrinking bigalloc file |
| systems. |
| |
| 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. |
| |
| 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) |
| |
| 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. |
| |
| Fixed support for 1k block file systems with the meta_bg feature. |
| |
| 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) |
| |
| 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) |
| |
| 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. |
| |
| Update Czech, Dutch, French, German, Polish, Spanish, Swedish, and |
| Vietnamese translations. (Addresses Debian Bug: #703048) |
| |
| Updated/fixed various man pages. (Addresses Debian Bugs: #719189, |
| #719184) |
| |
| Fixed various Debian Packaging Issues. (Addresses Debian Bug: #718725) |
| |
| |
| Programmer's Notes |
| ------------------ |
| |
| Fixed a lot of coverity, sparse, gcc -Wall, and clang warnings/nits. |
| |
| Allow the location of pkg-config files to be specified independent of |
| the libdir location via a makefile variable. |
| |
| 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 |
| |
| Allow the regression test suite to work correctly on systems which do |
| not have the "truncate" or "mksawp" programs. |
| |
| Allow e2fsck to build correctly on systems (such as Android) that do |
| not have the signal.h file. |
| |
| E2fsprogs now has code coverage testing which can be enabled using |
| "configure --enable-gcov". |
| |
| The libe2p.h header file can now be used included by C++ programs. |
| |
| 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. |
| |
| 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. |
| |
| 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. |
| |
| The e4defrag program will try to use fadvise64 or posix_fadvise64() if |
| it is present, which allows 64-bit offsets on 32-bit systems. |
| |
| |
| E2fsprogs 1.42.9 (December 28, 2013) |
| ==================================== |
| |
| Mke2fs will detect an attempt to create a file system on a loop |
| mounted file and complain without the -FF option. 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 so that progress information won't get leaked to stdout. |
| (Addresses Red Hat Bugzilla: #1327329) |
| |
| 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 deprecated (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, Swedish, 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 wrong 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 <dev>'. |
| |
| 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 <sys/quota.h>. |
| |
| 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 uninitialized 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, Swedish, 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 program 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 across 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 build 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 file 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 checksums 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 Swedish translations 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 segfault 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 signaling 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 especially 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. (Addresses Debian Bug: |
| #631498, #644792) |
| |
| Logsave's usage message has been fixed. (Addresses Debian Bug: |
| #619788) |
| |
| Avoid an infinite loop in ext2fs_find_block_device() if there are |
| symlink loops in /dev caused by a buggy udev. |
| |
| Added a useful "fallocate" program to the contrib directory. |
| |
| Fixed an ABI compatibility problem in libext2fs which broke the dump |
| program. Also added back some macros which dump needed so it could |
| compile against the latest version of ext2_fs.h (Addresses Debian Bug: |
| #636418) |
| |
| Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses |
| Debian Bug: #641667) |
| |
| Added internationalization support for libcom_err error table strings. |
| |
| Fixed various spelling mistakes found in various output strings found |
| by I18N translators. |
| |
| Update translations: French, Chinese, Germany, Indonesian, Swedish, |
| Vietnamese, Polish, Dutch, Czech. (Addresses Debian Bugs: #520985, |
| #620659) |
| |
| Fixed various Debian Packaging issues. (Addresses Debian Bugs: |
| #614662, #632169, #641838, #627535, #629355) |
| |
| Updated/clarified man pages. (Addresses Debian Bugs: #639411, |
| #642193, #634883) |
| |
| Programmer's Notes |
| ------------------ |
| |
| Initial support for quota as an integrated feature, where the quota |
| files are hidden system files that are automatically maintained by |
| e2fsck is present, although disabled by default. It must be enabled |
| by using the configure option --enable-quota. |
| |
| Reserved the on-disk fields for the metadata checksum and snapshot |
| features, which are currently in development. |
| |
| The ext2fs library now has the new functions ext2fs_punch(), |
| ext2fs_get_memzero() and ext2fs_file_get_inode(). |
| |
| The ext2fs library now has support for calculating the crc32c checksum |
| (via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le). |
| |
| The I/O manager now supports the discard operation. |
| |
| Reserved file system code points for new 1st class quota feature. |
| |
| Shortened the compilation lines by moving the autoconf defines to |
| a config.h header file. |
| |
| Fixed a potential free of an uninitialized pointer in |
| ext2fs_update_bb_inode(). |
| |
| Fixed miscellaneous gcc -Wall and coverity warnings. |
| |
| Fixed portability issues for Mac OS X, Hurd, and FreeBSD. |
| |
| Fixed a build failure when OMIT_COM_ERR is defined. |
| |
| Improved error checking and fixed memory leaks caused by error return |
| paths. |
| |
| Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow |
| the fsync() to be skipped. |
| |
| Added a test for extent-mapped journals by mke2fs and tune2fs. |
| |
| Added a test for creating a large (over 4GB) journal using mke2fs. |
| |
| Added a test to make sure the inode size remains constant. |
| |
| The regression test script now prints the list of which tests failed. |
| |
| The regression test system now uses /tmp for its scratch files, which |
| is often a tmpfs mounted file system and hence much faster. |
| |
| The i_e2image test was fixed so it works with valgrind. |
| |
| Tests that rely on debugfs are now skipped if debugfs wasn't built. |
| |
| Fixed the dependencies for "make check" so all required dependencies |
| are built before running the regression tests. |
| |
| A link to com_err.h is installed in $(includedir) during a "make install". |
| |
| The po/*.gmo files are automatically rebuilt if they are missing or |
| out of date. This helps out Debian packaging. |
| |
| Allow ext2fs_get_memalign() to compile on systems that don't have |
| posix_memalign(). |
| |
| Fixed a namespace leak in libext2fs (tdb_null). |
| |
