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. Fixed a bug which could cause badblocks to crash if there are millions 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
