1E2fsprogs 1.45.5 (January 7, 2020) 2================================== 3 4Updates/Fixes since v1.45.4: 5 6Fixes 7----- 8 9E2fsck will no longer force a full file system check if time-based 10forced checks are disabled and the last mount time or last write time in 11the superblock are in the future. 12 13Fix a potential out of bounds write when checking a maliciously 14corrupted file system. This is probably not exploitable on 64-bit 15platforms, but may be exploitable on 32-bit binaries depending on how 16the compiler lays out the stack variables. (Addresses CVE-2019-5188) 17 18Fixed spurious weekly e-mails when e2scrub_all is run via a cron job 19on non-systemd systems. (Addresses Debian Bug: #944033) 20 21Remove an unnecessary sleep in e2scrub which could add up to an 22additional two second delay during the boot up. Also, avoid trying 23to reap aborted snapshots if it has been disabled via e2scrub.conf. 24(Addresses Debian Bug: #948193) 25 26If a mischievous system administrator mounts a pseudo-file system such 27as tmpfs with a device name that duplicates another mounted file system, 28this could potentially confuse resize2fs when it needs to find the mount 29point of a mounted file system. (Who would have guessed?) Add some 30sanity checking so that we can make libext2fs more robust against such 31insanity, at least on Linux. (GNU HURD doesn't support st_rdev.) 32 33Tune2fs now prohibits enabling or disabling uninit_bg if the file system 34is mounted, since this could result in the file system getting 35corrupted, and there is an unfortunate AskUbuntu article suggesting this 36as a way to modify a file system's UUID on a live file system. (Ext4 37now has a way to do this safely, using the metadata_csum_seed feature, 38which was added in the 4.4 Linux kernel.) 39 40Fix potential crash in e2fsck when rebuilding very large directories on 41file systems which have the new large_dir feature enable. 42 43Fix support of 32-bit uid's and gid's in fuse2fs and in mke2fs -d. 44 45Fix mke2fs's setting bad blocks to bigalloc file systems. 46 47Fix a bug where fuse2fs would incorrectly report the i_blocks fields for 48bigalloc file systems. 49 50Resize2fs's minimum size estimates (via resize2fs -M) estimates are now 51more accurate when run on mounted file systems. 52 53Fixed potential memory leak in read_bitmap() in libext2fs. 54 55Fixed various UBsan failures found when fuzzing file system images. 56(Addresses Google Bug: #128130353) 57 58Updated and clarified various man pages. 59 60 61Performance, Internal Implementation, Development Support etc. 62-------------------------------------------------------------- 63 64Speed up e2fsck on file systems with a very large number of inodes 65caused by repeated calls to gettext(). 66 67The inode_io io_manager can now support files which are greater than 682GB. 69 70The ext2_off_t and ext2_off64_t are now signed types so that 71ext2fs_file_lseek() and ext2fs_file_llseek() can work correctly. 72 73Reserve codepoint for the fast_commit feature. 74 75Fixed various Debian packaging issues. 76 77Fix portability problems for Illumous and on hurd/i386 (Addresses Debian 78Bug: #944649) 79 80Always compile the ext2fs_swap_* functions even on little-endian 81architectures, so that debian/libext2fs.symbols can be consistent across 82architectures. 83 84Synchronized changes from Android's AOSP e2fsprogs tree. 85 86Updated config.guess and config.sub with newer versions from the FSF. 87 88Update the Chinese and Malay translations from the translation project. 89
