1E2fsprogs 1.40.8 (March 13, 2008) 2================================= 3 4Fixed e2image -I so it works on image files which are larger than 2GB. 5 6Fixed e2fsck's handling of directory inodes with a corrupt size field. If 7the size is larger than the number of blocks found in the inode, don't 8try to allocate extra empty blocks at the end of the directory to make 9up the difference; there's no point to doing that. In addition, if 10the size is not a multiple of a blocksize, always fix it. 11 12E2fsck handled a pass 2 "should never happen error" by not giving 13enough information and then core dumping. Unfortunately, it was all 14too easy to trigger the "should never happen" situation if a 15directory's inode size was not correct. This has been fixed, but 16e2fsck has also been taught how to handle this situation more 17gracefully, by simply removing the inode hash tree information, so 18that it can be rebuilt again after e2fsck's pass 3. (Addresses 19Launchpad Bug: #129395) 20 21Resize2fs had a bug resizing large inodes with extended attributes 22that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed 23completely on big-endian systems such as PowerPC. The bug should be 24completely fixed now. Yay for regression test suites. (Addresses Red 25Hat Bugzilla: #434893) 26 27Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese 28translations. Many thanks to Philipp Thomas from Novell for stepping 29up to become the new German translation maintainer! (Addresses Debian 30Bugs: #302512, #370247, #401092, #412882). 31 32When e2fsck is clearing a corrupt inode's HTREE directory information, 33make it clear that it is just clearing the HTREE information, not the 34entire inode. 35 36Fixed spelling mistakes, typos, and otherwise clarified man pages. 37 38Programmer's notes 39------------------ 40 41Add new functions, ext2fs_dblist_get_last() and 42ext2fs_dblist_drop_last(), which allows the caller to examine the last 43directory block entry added to the list, and to drop if it necessary. 44 45Fixed a portability problem in libblkid with DJGPP. 46 47Fix an obvious typo in an "internal error" message in e2fsck. Thanks 48to Philipp Thomas for pointing this out. 49 50If the info files are not built, change "make install" so it doesn't 51fail with an error code. 52 53 54E2fsprogs 1.40.7 (February 28, 2008) 55==================================== 56 57Remove support for clearing the SPARSE_SUPER feature from tune2fs, and 58depreciate the -s option, since it can result in filesystems which 59e2fsck can't fix easily. There are very good reasons for wanting to 60disable sparse_super; users who wants to turn off sparse_super can use 61debugfs. (Addresses Sourceforge Bug: #1840286) 62 63Add missing options to mke2fs's usage message. (Addresses Sourceforge 64Bug: #1751393) 65 66Fix bug in resize2fs when large (greater than 128 byte) inodes are 67moved when a filesystem is shrunk; it was only moving the first 128 68bytes, so extended attributes were not getting moved. (Addresses Red 69Hat Bugzilla: #434893) 70 71E2fsck now prints an explicit message when the bad block inode is 72updated, to avoid confusion about why the filesystem was modified. 73(Addresses Sourceforge Bug: #756460) 74 75Allow mke2fs and tune2fs manipulate the large_file feature. 76Previously we just let the kernel and e2fsck do this automatically, 77but e2fsck will no longer automatically clear the large_file feature. 78It still isn't really necessary to worry about this feature flag 79explicitly, but some users seem to care. (Addresses Red Hat Bugzilla: 80#258381) 81 82Suppress message about an old-style fstab if the fstab file is empty. 83(Addresses Debian Bug: #468176) 84 85Fix (really minor) bug in debugfs's find_free_block so it avoids 86reporting a free block more than once if there are too few free blocks 87in the filesystem. (Addresses Sourceforge Bug: #1096315) 88 89Change e2fsck to no longer clear the LARGE_FILES feature flag 90automatically, when there are no more > 2GB files in the filesystem. 91It's been almost a decade since there have been kernels that don't 92support this flag, and e2fsck clears it quietly without telling the 93user why the filesystem has been changed. 94 95Fix bug which could cause libblkid to seg fault if a device mapper 96volume disappears while it is being probed. (Addresses RedHat 97Bugzilla: #433857) 98 99Inhance e2fsck's reporting of unsupported filesystem feature flags. 100(Addresses Sourceforge Feature Request: #1175808) 101 102Fix option syntax in dumpe2fs for explicit superblock and blocksize 103parameters. What was currently documented in the man page has been 104broken for some time, due to getopt() implementation changes. The 105option sytax has been changed to one which is can be more portable 106supported and which is consistent with the format for extended options 107in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994) 108 109Add support to tune2fs to clear the resize_inode feature. This 110requires an fsck afterwards.

This allows for much better future 221compatibity with ext4 and speeds up extended attributes even on ext3 222filesystems. 223 224Teach e2fsck to ignore certain "safe" filesystem features which are 225set automatically by the kernel. Having the kernel set features 226automagically behind the user's back is a bad idea, and we should try 227to break the kernel of this habit, especially for the newer ext4 228feature flags. But for now, we will try to avoid needless full checks 229which can annoy users who are doing fresh installs. 230 231Add support in tune2fs and mke2fs for making a filesystem as being "ok 232to be used with test kernel code". This will be needed for using test 233filesystems with the latest ext4 kernel code. 234 235Change e2fsck -fD so that it sorts non-htree directories by inode 236numbers instead of by name, since that optimizes performances much 237more significantly. (Addresses-Sourceforge-Feature-Request: #532439) 238 239If e2image fills the disk, fix it so it exits right away instead of 240spewing large numbers of error messages. 241(Addresses-Sourceforge-Feature-Request: #606508) 242 243If ftruncate64() is not available for resize2fs, let it use ftrucate() 244instead, but have it check to see if the size would get truncated, and 245skip calling ftruncate in that case. 246 247Add support for detecting HFS+ filesystems in the blkid library. 248 249Add supprt in the blkid library for ext4/ext4dev filesystems. 250 251Fix a bug in blkid where it could die on a floating point exception 252when presented with a corrupt reiserfs image. 253 254Fix blkid's handling of ntfs UUID's so that leading zeros are printed 255such that UUID string is a fixed length. 256 257Add sample python bindings for the uuid library to the contrib 258directory. (Addresses-Sourceforge-Patches: #778817) 259 260Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it 261will work with large files. (Addresses Sourceforge Feature Request: 262#1257500 and Sourceforge Support Request: #1253511) 263 264Allow the debugfs 'undel' command to undelete an inode without linking 265it to a specific destination directory, since this might require 266allocating blocks that could overwrite some yet-to-be-recovered 267deleted files. (Addresses-Sourceforge-Feature-Request: #967141) 268 269Update Swedish translations from the Translation Project. 270 271Programmer's Notes: 272------------------- 273 274Fix configure handling of --sbindir (which should rarely be used, but 275someone did complain, so let's fix it). (Addresses Sourceforge Bug: 276#498381) 277 278Updated e2fsprogs.spec file to include a new uuidd package 279 280Use pkg-config to determine where to find the devmapper library so we 281can find out where it is located on different distributions. 282 283Fix Makefile race so that "make -j3 distclean" works correctly 284 285Fix portability problems on non-Linux/non-Hurd/non-Masix systems, 286especially on MacOS X systems.

This can lead to either a 363crash or potentially a heap-based buffer overflow crash. No known 364exploits exist, but main concern is where an untrusted user who 365possesses privileged access in a guest Xen environment could corrupt a 366filesystem which is then accessed by the pygrub program, running as 367root in the dom0 host environment, thus allowing the untrusted user to 368gain privileged access in the host OS. Thanks to the McAfee AVERT 369Research group for reporting this issue. (Addresses CVE-2007-5497.) 370 371Fix hueristics in blkid which could cause a disk without partitions to 372be incorrectly skipped when a loopback device is present.

Work around this as best as we can by 399providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can 400be set on Ubuntu systems.

(Addresses Red 404Hat Bugzilla #151533.) 405 406Fix e2fsck so that if the superblock is corrupt, but still looks 407vaguely like an ext2/3/4 superblock, that it automatically tries to 408fall back to the backup superblock, instead of failing with a hard 409error. 410 411Make the e2fsprogs program more robust so that they will not crash 412when opening a corrupt filesystem where s_inode_size is zero. 413 414Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric 415arguments are detected as such and the parse error is reported to the 416user. (Addresses Debian Bug #435381.) 417 418Change e2fsck so it will not complain if a file has blocks reallocated 419up to the next multiple of a system's page size. 420 421Fix bug in ext2fs_check_desc() which will cause e2fsck to complain 422about (valid) filesystems where the inode table extends to the last 423block of the block group.

Fortunately 457ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in 458places where it is extremely unlikely to run into this corner case. 459 460Fix missing dependency which would cuase parallel builds to fail. 461(Addresses Sourceforge Bug #1842331.) 462 463Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c 464calling open(O_CREATE) with a missing mode parameter. 465 466Fix the test_ss.c in lib/ss so it can be used as an example 467application program for the library as well as a regression test 468suite. 469 470Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes 471are properly passed back up through the call stack. 472 473E2fsprogs 1.40.2 (July 12, 2007) 474================================ 475 476A recent change to e2fsck_add_dir_info() to use tdb files to check 477filesystems with a very large number of filesystems had a typo which 478caused us to resize the wrong data structure. This would cause a 479array overrun leading to malloc pointer corruptions and segfaults. 480Since we normally can very accurately predict how big the the dirinfo 481array needs to be, this bug only got triggered on very badly corrupted 482filesystems. 483 484Fix a bug in e2fsck which caused it to incorrectly salvange 485directories when the last entry's rec_len is bogusly too big. This 486resulted in a nonsense filesystem corruption to be reported, and 487required a second run of e2fsck to fully fix up the directory. 488 489Update tune2fs man page to include more discussion of reserved blocks 490(Addresses Launchpad bug #47817) 491 492Update Turkish, Polish, Dutch, and Vietnamese PO files from the 493Translation Project 494 495 496E2fsprogs 1.40.1 (July 7, 2007) 497=============================== 498 499Fix bug which could cause libblkid to loop forever. When revalidating 500a partition where there is obsolete information in /etc/blkid.tab, we 501end up freeing a the type tag without clearing dev->bid_type, causing 502blkid_verify() to loop forever. (Addresses Debian Bug: #432052) 503 504The Turkish translation has a bug in it where it has the translation 505of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at 506@E, recursively, forever, until the stack fills up and e2fsck core 507dumps. We fix this by making e2fsck stop @-expansions after a 508recursive depth of 10, which is far more than we need. 509(Addresses Sourceforge Bug: #1646081) 510 511Compile the default mke2fs.conf into mke2fs program.

(Obviates Gentoo patch: 543e2fsprogs-1.32-mk_cmds-cosmetic.patch) 544 545Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high 546priority" environment variable that overrides all others, where as 547LANG is the lowest priorty environment variable. If LC_ALL is set, it 548doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and 549the all the rest are set.

Fortunately bid_type isn't used much, and bid_label 564and bid_uuid is only used by debugging code, so the impact of this bug 565was very minor. 566 567Mke2fs will now store the RAID stride value when a filesystem is 568created with a requested RAID stride, and then use it automatically in 569resize2fs. 570 571Mke2fs has a sanity check added to make sure (inode_size * num_inodes) 572isn't too big. In some cases Lustre users have tried specifying an 573inode size of 4096 bytes, while keeping an inode ratio of one inode 574per 4096 bytes. 575 576Improve sanity check in e2fsck's algorithm for finding a backup 577superblock, so that it won't accidentally find a superblock that was 578located in the journal, and then later reject it as being not a valid 579backup superblock. 580 581Fix e2fsck get_size logic so that it will work with the Linux floppy 582driver. The Linux floppy driver is a bit different from the other 583block device drivers, in that if the device has been opened with 584O_EXCL, it disallows another open(), even if the second open() does 585not have the O_EXCL flag.

The original code only checked the direct blocks to 612make sure the journal inode was sane. Unfortunately, if some or all 613of the indirect or doubly indirect blocks were corrupted, this would 614not be caught. 615 616Add support in blkid to detect LUKS encrypted partitions. 617 618Add extra sanity checks for extended attributes in the case where the 619size is zero but the offset is very large. 620 621Fix byte-swapping issues for large inodes in ext2fs_read_inode_full() 622and ext2fs_get_next_inode_full(). 623 624Clarify the copyright licenses used by the various libraries in 625the top-level COPYING file (Red Hat Bugzilla: 166058) 626 627Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane. 628 629Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's. 630 631Remove check in e2fsck which requires EA's in inodes to be sorted; 632they don't need to be sorted, and e2fsck was previously wrongly 633clearing unsorted EA's stored in the inode structure. 634 635Allow mke2fs or tune2fs to create a substantially larger journal (up 636to 10,240,000 blocks). 637 638Fix MD superblock detection, and make sure the correct UUID is 639reported from the MD superblock. 640 641Fix a signed vs. unsigned bug in debugfs. 642 643Enhance debugfs's date parser so that it accepts integer values. 644 645Fix e2fsck's pass1c accounting so it doesn't terminate too early if a 646file with multiply claimed blocks is hard linked. or not at all if the 647root directory contains shared blocks 648 649Enhance debugfs so it can modify the block group descriptors using the 650command set_block_group_descriptor. 651 652Improve e2fsck's reporting of I/O errors so it's clearer what it was 653trying to do when an error happens 654 655Fix a bug in in how e2fsprogs byte swaps inodes containing fast 656symlinks that have extended attributes.

If the 875COMERR_DEBUG_FILE environment variable is set (and the process is not 876setuid) the debugging messages may be redirected to a file. 877 878Change all of the e2fsprogs programs to use the newer add_error_table() 879and remove_error_table() interfaces instead of the much older 880initialize_*_error_table() function. 881 882Add TDB support into the ext2fs library. This allows us to have a 883guaranteed library we can count on always being present so we can 884store data in an on-disk database. 885 886Add support for using TDB to store the icount data, so we don't run out 887of memory when checking really large filesystems. 888 889Change the regression test suite so that it skips empty test directories. 890 891Define the l_i_iversion field in ext2_inode. The l_i_version field is 892now defined from the old l_i_reserved1 field in the ext2 inode. This 893field will be used to store high 32 bits of the 64-bit inode version 894number. 895 896Add Makefile production rule for e2fsprogs.spec in case it gets 897deleted. 898 899Add new function profile_get_uint() to allow for a clean way to fetch 900unsigned integers from the context. 901 902Add test to make sure the ext2 superblock structure is 1024 bytes. 903 904Fix typo in name of f_dup4 regression test 905 906Add new function blkid_gc_cache() which performs a garbage collection 907pass on the /etc/blkid.tab file. 908 909The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In 910general, only e2fsck (after the filesystem is clean), tune2fs, and 911resize2fs should change the backup superblocks by default. Most 912callers of ext2fs_open() should not be touching any superblock fields 913which require the backups to be touched. 914 915Add new function to libext2fs, ext2fs_default_journal_size(), which 916returns the default journal size. 917 918 919E2fsprogs 1.39 (May 29, 2006) 920============================= 921 922Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems 923between 2**31 and 2**32 blocks. 924 925Change mke2fs to use /etc/mke2fs.conf as a configuration file to 926configure the filesystem features, blocksize, and inode_ratio for 927different filesystem types. 928 929Mke2fs will now create filesystems hash trees and on-line resizing 930enabled by default, based on the new /etc/mke2fs.conf file. 931 932The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the 933filesystem device node in exclusive mode to prevent accidents by 934system administrators. In the case of resize2fs and mke2fs, it will 935only use exclusive mode if the filesystem is not mounted. 936 937Fixed a bug in mke2fs which caused it to to fail when creating the 938resize inode for large filesystems. (Addresses Debian Bug #346580) 939 940When allocating space for the RAID filesystems with the stride 941parameter, mke2fs will now place each portion of the group's inode 942table right up after the superblock (if present) in order to minimize 943fragmentation of the freespace. 944 945Speed up mke2fs and e2fsck by writing inode and block bitmaps more 946efficiently by writing the inode and block bitmaps in one pass, thus 947reducing the number of disk seeks required. 948 949Add support for on-line resizing to resize2fs. 950 951Fix blkid library so that logic to determine whether or not a device's 952cached information in /etc/blkid.tab needs to be verified or not 953doesn't get confused by a system clock which is insane (for example, 954if the battery is dead on a Macintosh running PPC Linux. (Addresses 955Red Hat Bug: #182188) 956 957The blkid library will now store the UUID of the external journal used 958by ext3 filesystems, so that in the future, the userspace mount binary 959can use this to find the location of the external journal and pass 960this information to the kernel. 961 962E2fsck will now consult a configuration file, /etc/e2fsck.conf to 963control how various options should be handled.

This would 1108break compiles on the sparc architectures when using gcc. 1109 1110In the libext2fs library, add the new field fs->now which if non-zero 1111is used instead of the system time when setting various filesystem 1112fields (last modified time, last write time, etc.) 1113 1114Fix gcc 4.01 complaints by adding a missing #include <string.h> to 1115ext2fs.h which is needed since the inline functions use memcpy(). 1116(Addresses Sourceforge Bug #1251062) 1117 1118Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in 1119the build system when building files in the util directory which are 1120needed during the build process. This avoids potential problems when 1121cross-compiling and some of the options specified in CFLAGS or LDFLAGS 1122are not recognized as valid by the host compiler. (Addresses 1123Sourceforge Bug #1261547) 1124 1125Clean up the blkid library by making the superblock and generic i/o 1126functions to be more generic. Clean up interface to the probe 1127function, and fix memory leak. Finallly, remove an unneeded reference 1128to probe.h in the lib/blkid/resolve.c 1129 1130Add an ext2fs_read_bb_FILE regression test to confirm proper detection 1131of invalid block #'s. 1132 1133The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to 1134indicate that the the function read/writes the memory location. 1135 1136Fix various gcc -Wall complaints. 1137 1138Add a dependency to make sure that the subdirectories are created 1139before creating all of the object files, in order to address parallel 1140build problem in the library Makefiles. (Addresses Sourceforge Bug: 1141#1261553) 1142 1143Add $(LDFLAGS) to the command line argument when generating an ELF or 1144Solaris shared library, to allow cross-compile and other builds that 1145might need to specify -L paths to needed libraries. (Addresses 1146Sourceforge Bug #1261549) 1147 1148Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially 1149intended for testing purposes. It allows an ext2/ext3 developer to 1150create very large filesystems using sparse files where most of the 1151block groups are not initialized and so do not require much disk 1152space. Eventually it could be used as a way of speeding up mke2fs and 1153e2fsck for large filesystem, but that would be best done by adding an 1154RO_COMPAT extension to the filesystem to allow the inode table to be 1155lazily initialized on a per-block basis, instead of being entirely 1156initialized or entirely unused on a per-blockgroup basis. 1157 1158Fix backwards compatibility so e2fsprogs will better compile on Linux 11592.0.35 systems. 1160 1161Make test scripts more robust against locale-related environment variables 1162 1163Fix type warning problem with sizeof() in ext2fs_open2(). 1164 1165Fix type warning problem with time_t in debugfs. 1166 1167 1168E2fsprogs 1.38 (June 30, 2005) 1169============================== 1170 1171Fix blkid's test programs (built with "make check") compile correctly 1172even without "configure --enable-blkid-debug". 1173 1174Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict 1175type aliasing rules on newer gcc compilers. (Addresses Red Hat 1176Bugzilla ##161183.) 1177 1178Fix com_err library to make it more compatible with recent changes 1179made to the com_err library in MIT Kerberos V5 version 1.4. 1180(Addresses Sourcefroge Bug #1150146) 1181 1182General cleanup of messages printed by e2fsprogs programs for grammar, 1183consistency, and to make life easier for translators. Fixed a few 1184strings containing English that had not been marked as needing 1185translations. Removed strings that do not need to be translated, to 1186make life easier for translators. 1187 1188Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to 1189test to see if a device appears to be in use instead of just relying 1190on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594). 1191 1192Fix portability problem in the filefrag program affecting platforms 1193where the size of an integer is smaller than the size of a long. 1194(Addresses Debian Bug #309655) 1195 1196Mke2fs will now use a larger journal by default for filesystems 1197greater than 4GB. (128 MB instead of 32MB). 1198 1199Mke2fs will refuse to create filesystems greater than 2**31-1 blocks, 1200unless forced. This is to avoid signed vs. unsigned kernel bugs in 1201block numbers that still need to be fixed. 1202 1203The blkid program has a new option which will more efficiently search 1204for device when it is known (or expected) that only one matching 1205device will be found in the system, such as when doing a lookup by 1206UUID. 1207 1208Debian's e2fsprogs-specific initrd fragment will avoid including 1209unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD 1210and LD_LIBRARY_PATH, and filtering out libraries found in 1211/etc/ld.so.preload. (Addresses Debian Bug: #304003) 1212 1213Fixed a potential portability issue in the blkid programs for 1214architectures where the char type is unsigned. (Addresses Sourceforge 1215Bug: #1180585) 1216 1217Fix a bug in filefrag so that it doesn't falsely count an extra 1218discontinuity when the first block found is an indirect block. 1219(Addresses Debian Bug #307607). 1220 1221Fix blkid's recognition of cramfs filesystems, and enhance it to be 1222able to handle cramfs labels. 1223 1224Fix debugfs's stat command to not core dump when a filesystem is not 1225open. 1226 1227Fix e2fsck's handling of error conditions caused by the resize inode 1228claiming blocks that are also used by other inodes, a filesystem 1229corruption which was commonly caused by a bug in Fedora Core 3's 1230resize2fs program. 1231 1232Fixed bug in filefrag which caused it to fail on non-ext2/3 1233filesystems. (Addresses Debian Bug: #303509) 1234 1235If the superblock last mount time indicates that the system clock may 1236not be accurate, then e2fsck will omit checking inodes' deletion time 1237field for indications of a potential corrupted orphaned inode list. 1238(Previously e2fsck only ommited these LOW_DTIME checks when the 1239superblock's last write time looked insane.) 1240 1241Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs. 1242(Addresses Debian bug #302200) 1243 1244Make the blkid library more paranoid about being run from setgid 1245programs, and to use __secure_getenv() from libc if it is available. 1246 1247Fixed spelling mistakes, typos, and otherwise clarified man pages. 1248(Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593 1249and Sourceforge Bug: #1189803) 1250 1251Updated and fixed translations. 1252 1253Fixed various Debian packaging issues --- see debian/changelog for 1254details. 1255 1256Programmer's notes: 1257------------------- 1258 1259Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been 1260changed to take an unsigned int for the bit number. Negative bit 1261numbers were never allowed (and didn't make any sense), so this should 1262be a safe change. This is needed to allow safe use of block numbers 1263greater than or equal to 2**31. 1264 1265The compile_et program will avoid recreating generated foo_err.c and 1266foo_err.h files if no changes are necessary. The compile_et program 1267will also atomically replace these files to avoid a potential parallel 1268build race problem on SMP systems. (Addresses Sourceforge Bug: 1269#1157933) 1270 1271Added a new function to the blkid library, blkid_probe_all_new(), 1272which only probes newly added disk devices, and change 1273blkid_find_dev_with_tag() to use this function so that when a 1274requested tag is not found, devices that were previously not checked 1275are searched before searching all devices in the system. 1276 1277Added new functions to the blkid library, blkid_dev_set_search() and 1278blkid_dev_has_tag(). 1279 1280E2fsck's problem strings can now use @m and @n as abbrevations for 1281"multiply-claimed" and "invalid", respectively. 1282 1283The e2fsprog.pot file now has an explanation of how the @-expansion 1284and %-expansion works, and strings in e2fsck/problem.c which contain @ 1285characters now have comments in e2fsprogs.pot with the @-expansion to 1286make life easier for translators. 1287 1288Fixed missing return values in the ext2fs library which could cause it 1289to return random garbage in certain error conditions. 1290 1291Allow the current time to be overriden via the E2FSCK_TIME environment 1292variable for use in regression tests. 1293 1294The test scrpit driver program now exits with a non-zero status if 1295there any of its test that it ran failed. 1296 1297Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge 1298Bug: #1157933) 1299 1300Fixed "make check" so that it compiles correctly even when e2fsprogs' 1301header files have not be installed in the system include directories. 1302(Addresses Sourceforge Bug: #1180572) 1303 1304Fixed gcc -Wall nits. 1305 1306 1307E2fsprogs 1.37 (March 21, 2005) 1308=============================== 1309 1310Add support for checking the validity of Extended Attributes stored in 1311inodes to e2fsck. 1312 1313Add support for dumping the contents of large inodes to debugfs, 1314including the extended attributes stored in inodes. 1315 1316Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that 1317when we create a new inode we make sure that the extra information in 1318the inode (any extra fields in a large inode and any ea-in-inode 1319information) is initialized correctly. This can take place when 1320mke2fs creates the root and lost+found directory, when e2fsck creates 1321a new root inode or a new lost+found directory, and when the user uses 1322the debugfs write, mknod, or mkdir commands. Otherwise, the newly 1323create inode could inherit garbage (or old EA information) from a 1324previously deleted inode. 1325 1326Fixed a bug in e2fsck so it would notice if a file with an extended 1327attribute block was exactly 2**32 blocks, such that i_blocks wrapped 1328to zero. 1329 1330Added support to filefrag to detect files which are using the new 1331experimental file extents format, and use the non-ext2 algorithm in 1332that case. Fixed a bug to avoid reporting a false discontinuity if 1333there is one or more unallocated blocks at the beginning of a file. 1334 1335Duplicated a check for noticing whether or not the number of blocks 1336(given a certain blocksize) is greater than 2**32 when the 1337BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This 1338allows mke2fs to automatically use a larger blocksize when creating a 1339filesystem on a very large device when run on systems that do not 1340support BLKGETSIZE64. 1341 1342Fix the I18N build which was broken in e2fsprogs 1.36 because the 1343build system had been switched to treat the .gmo files as shipped 1344files (for backwards compatibility with systems that have older GNU 1345I18N tools installed), but the gen_tarball.in script was still 1346removing the .gmo files from the official source distribution. 1347 1348Fixed various Debian packaging issues --- see debian/changelog for 1349details. (Addresses Debian Bugs ##296769, #299341) 1350 1351Programmer's notes: 1352------------------- 1353 1354Added new functions to the e2p library which convert between a string 1355and os_type: e2p_os2string() and e2p_string2os(), and used them to 1356make the generated binaries more compact. 1357 1358Fixed a compile-time error on Darwin systems. 1359 1360Cleaned up the lib/ext2fs Makefile slightly. 1361 1362 1363E2fsprogs 1.36 (February 4, 2005) 1364================================= 1365 1366All of the patches that were applied to Fedore Core 3's 1367e2fsprogs-1.35-11.2 have been integrated, although sometimes with a 1368lot of bug fixes first. Users of Fedora Core 3 are strongly 1369encouraged to upgrade to e2fsprogs 1.36 as soon as possible. 1370 1371Add support for filesystem with the online resizing via resize inode 1372feature. Fixed numerous bugs from the Fedora patches. The Fedora 1373patches also didn't bother to do any consistency checking on the 1374resize inode, or add any tests to the regression test suite. The "-R 1375resize=4g" option to mke2fs was a no-op in the Fedora patches, despite 1376being listed in mke2fs's usage message. All of these shortcomings 1377have been corrected. 1378 1379E2fsck can also also fix filesystems trashed by Fedora's resize2fs 1380program. In order to do this, the user must run the commands: 1381 1382 debugfs -w /dev/hdXXX -R "features ^resize_inode" 1383 e2fsck -f /dev/hdXXX 1384 1385Optionally, the ext2prepare command can be used to re-enable online 1386resizing after the filesystem has been fixed. 1387 1388The fsck program will now accept an optional filedescriptor argument 1389to the -C option. (The Fedora version of this patch would sometimes 1390cause fsck to ignore a parameter on fsck's command line in some rare 1391cases, sigh.) 1392 1393Make sure e2fsprogs doesn't write garbage into the reserved portion of 1394large inodes. 1395 1396Make sure resize2fs releases the blocks belonging to the old inode 1397table blocks when moving the inode table. (Addresses Debian Bug: 1398#290894) 1399 1400Skip the r_resize_inode test if resize2fs is not compiled (due to 1401configure --disable-resizer) 1402 1403E2fsck now checks the summary filesystem accounting information, and 1404if any of the information is obviously wrong, it will force a full 1405filesystem check. (Addresses Debian Bug #291571) 1406 1407Fix e2fsck to not complain when the resize_inode feature is enabled, 1408s_reserved_gdt_blocks is zero, and there is no DIND block allocated in 1409the resize inode. 1410 1411Fix e2fsck to note delete symlinks that contain an extended attribute 1412after the ext_attr feature flag has been cleared. (Addresses Red Hat 1413Bugzilla #146284). 1414 1415Add new utility program, copy_sparse.c, which is very useful 1416for dealing with large sparse files (such as e2image files). 1417 1418Add support for jnl_blocks[] for debugfs's set_super_value. 1419 1420Fix filefrag so that it works correctly with sparse files. 1421 1422Filefrag -v will print first and last blocks. 1423 1424Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs 1425and dumpe2fs. 1426 1427Add mke2fs support so that it can support filesystems larger than 4TB 1428automatically, by retrying with a 4k blocksize if the device size is 1429too big to be expressed using a 1k blocksize. (Addresses Sourceforge 1430bug #1106631) 1431 1432Change blkid to test for NTFS first because Windows sometimes doesn't 1433clear enough of the parition to confuse the probing routines into 1434thinking the old filesystem type is still valid. (Addresses Debian 1435Bug #291990) 1436 1437Add support for swap partition label and uuid's in the blkid library. 1438 1439Add support to the blkid library to recognize Oracle ASM volumes. 1440 1441Make blkid -t display all devices that match the specified criteria, 1442not just the first one, and work more consistently when the blkid 1443cache file is not available or set to /dev/null. (Addresses Debian 1444Bug #290530 and #292425) 1445 1446Badblocks will now correctly display block numbers greater than 1447999,999,999 in its progress display. 1448 1449The tune2fs program will not allow the user from setting a ridiculous 1450number of reserved blocks which would cause e2fsck to assume the 1451superblock was corrupt. E2fsck's standards for what is a ridiculous 1452number of reserved block has also been relaxed to 50% of the blocks in 1453the filesystem. 1454 1455The blkid library will return vfat in preference to msdos, and ext3 in 1456preference to ext2 (if the journalling flag is set) so that mount will 1457do the right thing. (Addresses Debian bug #287455) 1458 1459Mke2fs will now use the -E option for extended options; the old -R 1460(raid options) option is still accepted for backwards compatibility. 1461Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707) 1462 1463Mke2fs will now accept a size in megabytes, gigabytes, and other units 1464(via "32m" or "4g" on the command line) if the user finds this more 1465convenient than specifying a block count. 1466 1467Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode 1468cache conherency problem. 1469 1470Debugfs now supports a new command, set_inode_field, which allows a 1471user to manually set a specific inode field more conveniently, as well 1472as set entries in the indirect block map. 1473 1474Debugfs's set_super_value command has been enhanced so that the user 1475can set most superblock fields, including the date/time fields and 1476some of the more newsly added superblock fields. 1477 1478E2fsprogs programs now accept an offset to be passed to the file 1479specifiers, via the syntax: "/tmp/test.img?offset=1024". 1480 1481E2fsprogs programs will now accept blocksizes up to 65536; kernel 1482support on the x86 doesn't exist for now, but it can be useful on 1483other architectures with page sizes greater than 4k. There are 2.6 1484kernel patches out there which enable this, but they are of this 1485writing still experimental. 1486 1487The e2image command now takes the -s option which will scramble 1488directory entries for raw image files. 1489 1490Fix a file descriptor leak in the filefrag program. 1491 1492Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not 1493present. 1494 1495Fix bug in debugfs where kill_file would lead to errors when deleting 1496devices and symlinks. (Sourceforge Bugs #954741 and #957244) 1497 1498Fix bug in the blkid library when detecting the ocfs1 filesystem 1499 1500Remove obsolete EVMS 1.x and a.out DLL support. 1501 1502E2fsck will attempt to recover from a journal containing illegal blocks. 1503 1504Fixed two potential ordering constraint problems in e2fsck which might 1505cause the filesystem to be corrupted if e2fsck is interrupted during a 1506(extremely narrow) race window. Thanks to Junfeng Yang from the 1507Stanford Metacompilation group for pointing this out. 1508 1509Fixed bug in e2fsck where it would not accurately detect whether or 1510not the system is running on adaptor if the ACPI device representing 1511the AC adapter didn't correspond to the what was used on IBM 1512Thinkpads. 1513 1514Change e2fsck to accept directories greater than 32MB. 1515 1516Fix e2fsck so that a checkinterval of zero disables a time-based check 1517of the filesystem. 1518 1519Debugfs will check the DEBUGFS_PAGER enviroment variable in preference 1520to the PAGER environment variable. (Addresses Debian Bug #239547) 1521 1522Tune2fs will not mark rewrite the superblock if the feature bitmasks 1523are not modified. 1524 1525The debugfs program will set the filetype information when creating a 1526link. 1527 1528Add debugfs -d option to use a separate source of data blocks when 1529reading from an e2image file. 1530 1531Add e2image -I option which allows the e2image metadata to be 1532installed into a filesystem. 1533 1534Fixed bug in the badblocks program which caused "done" to always 1535appear in english even when a translation was available. (Addresses 1536Debian Bug #252836) 1537 1538The blkid program has a new option -o which controls the output format 1539of the blkid program; this is makes blkid more convenient to use in 1540shell scripts. 1541 1542Fix a minor bug in uuid library, which was not using the full 14 bits 1543of clock sequence when generating UUID's. 1544 1545Fix a Y8.8888K problem in the uuid library. 1546 1547Logsave now creates a new session id for itself to avoid getting 1548killed by init whan transitioning between init levels. 1549 1550Change the licensing of the UUID library to be the 3-clause BSD-style 1551license; this allows Apple to use the uuid library in Darwin. 1552 1553Add ocfs and ocfs2 probe support into the blkid library. 1554 1555Fix a memory and file descriptor leak in the blkid library. 1556 1557The blkid library will revalidate the device if the system time is 1558earlier than last verification time of the device, since that 1559indicates that the system time is probably nottrustworthy. 1560 1561The blkid library will override the default location of the blkid.tab 1562file by the BLKID_FILE environment variable, if it is available. 1563 1564Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6. 1565 1566Add various portability fixes for lame new versions of glibc, Darwin 1567and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian 1568Bugs #239934, #264630, #269044, #255589, #289133) 1569 1570Add support for Windows 9x/NT under Cygwin. 1571 1572Updated and clarified various man pages. (Addresses Debian Bugs #236383, 1573 #241940, #238741, #242995, #256669, #268148, #256760, #273679) 1574 1575Updated and fixed translations. (Addresses Debian bugs #244105, #262836) 1576 1577Update the rpm spec files so that it works better with Fedora core 2 1578and RH9. 1579 1580Fixed various Debian packaging issues (see debian/changelog). In 1581particular, fixed the Debian initrd scripts. (#241183, #248050, 1582#253595, #247775) 1583 1584 1585Programmer's notes: 1586------------------- 1587 1588Fixed various gcc -Wall warnings. 1589 1590The uuid library now has new functions uuid_unparse_upper() and 1591uuid_unparse_lower() which forces the case of the hex digits to be 1592upper case, or lower case. 1593 1594The build process has been speeded up by enhancing the subst program 1595to update the modtime on the generated files even when the generated 1596file hasn't changed. 1597 1598The uuid library now uses C99 stdint.h types instead of custom types. 1599 1600Updated config.guess and config.sub with newer versions from the FSF. 1601 1602Removed out of date .cvsignore files from the source distribution. 1603 1604The ext2fs_unlink() function will return an error if both the name and 1605inode number are unspecified, to avoid doing something surprising 1606(such as unconditionally deleting the first directory entry). 1607Directory entries are now deleted by coalescing them with the previous 1608directory entry if possible, to avoid directory fragmentation. This 1609is not an issue with the e2fsprogs suite, but may be a problem for 1610some of the users of libext2fs, such as e2tools. 1611 1612Add support for version numbers of the form "1.36-rc1". 1613 1614Fix build of mke2fs.static. 1615 1616Add basic ext2fs library support for large (EA in inode) inodes. 1617 1618The test_io mechanism can now abort after n reads or writes to a 1619particular block. The block is specified by TEST_IO_BLOCK environment 1620variable, and the read/write count by the TEST_IO_READ_ABORT and 1621TEST_IO_WRITE_ABORT environment variables. The block data is now only 1622dumped if the 0x10 bit is set in TEST_IO_FLAGS. 1623 1624UUID_DEFINE() in the uuid library now creates a static variable, with 1625__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can 1626be used in header files. 1627 1628Add support for the install-strip and install-shlibs-strip targets, as 1629suggested by the GNU coding guielines. "make install" no longer 1630strips the binaries which are installed. 1631 1632Remove support for the --enable-old-bitops configure option which was 1633only for very old sparc systems. 1634 1635Remove support for --enable-clear-htree; this was only needed during 1636the early development of the htree patch. 1637 1638Use Linux-kernel-style makefile output so it is easier to see compiler 1639warnings. 1640 1641Update gettext files to version 0.14.1. 1642 1643Update to use autoconf 2.5x. 1644 1645Improved support for compiling e2fsprogs under dietlibc. 1646 1647Make e2fsprogs portable to Solaris and FreeBSD systems. 1648 1649Add blkid_verify(), blkid_get_library_version(), and 1650blkid_parse_version_string() functions to the blkid library. 1651 1652Add pkg-config files for e2fsprogs's libraries. 1653 1654Fix "make uninstall" to so that it removes everything that is installed. 1655 1656Add a configure --enable-maintainer-mode option which enables the 1657makefile rules to rebuild the configure script from configure.in, and 1658to reubuild the .gmo files in po directory. 1659 1660Drop the sparc assembly bitwise operations; it's less efficient 1661than the GCC 3.4 compile code and triggers compiler warnings on 1662sparc64. Thanks to Matthias Andree for his analysis and suggestions. 1663(Addresses Debian Bug #232326) 1664 1665 1666E2fsprogs 1.35 (February 28, 2004) 1667================================== 1668 1669E2fsck has a new -k option, which in conjunction with the -c options, 1670preserves the existing badblocks list. 1671 1672Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d. 1673 1674E2fsprogs will now deal correctly with symlinks that contain 1675extended attribute information, which can be created using SE Linux. 1676(Addresses Debian Bug #232328) 1677 1678Remove a double longjump into an invalid stack frame bug in e2fsck. 1679(This was during an abort sequence, which normally worked on Linux and 1680caused a core dump on other operating systems.) 1681 1682Fix NLS bug in e2fsck, by avoiding trying to expand an empty string 1683(the NLS library will replace "" with the .po header information). 1684 1685Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core 1686dump due to a division by zero error. (Addresses Debian bug #207082) 1687 1688Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem 1689when reconnecting a directory requires creating a lost+found 1690directory. (Addresses Debian bug #219640). 1691 1692Fixed a bug where e2fsck would bomb out if a journal needed to be 1693replayed when using an alternate superblock. 1694 1695E2fsck will give an extra grace period before actually forcing a check 1696if the laptop is running on battery. The next time fsck runs while 1697the system is on the AC mains, or after the grace period is exceeded, 1698the filesystem will be checked. (Addresses Debian bug #205177) 1699 1700E2fsck will inform the user when there are 5 or fewer mounts before a 1701filesystem check will be forced. (Addresses Debian bug #157194) 1702 1703Fix e2fsck's handling of corrupted indirect blocks in the bad block. 1704We now correctly handle the case where there is an overlap between a 1705block group descriptor or a superblock and a bad block indirect block. 1706In the case where the indirect block is corrupted, we now suggest 1707"e2fsck -c". 1708 1709Fix byte swap bugs in e2fsck that caused the journal backup location 1710in the superblock and symlinks created by SE Linux to be cleared 1711by e2fsck on big-endian machines. (Addresses Debian bug #228723) 1712 1713E2fsck -c now replaces the current list of bad blocks with the ones 1714found by badblocks. 1715 1716Fix bugs in e2fsck and tune2fs which could cause a core dump if a 1717non-existent LABEL or UUID specifier is to e2fsck or tune2fs. 1718 1719Fix a potential bug in e2fsck which could cause it to core dump when 1720trying to print the location of the backup superblock. 1721 1722Protect against a potential core dump in e2fsck when printing a 1723message about backup superblocks. 1724 1725Add support for backing up the journal inode location in the 1726superblock. E2fsck will automatically save the journal information in 1727the superblock if it is not there already, and will use it if the 1728journal inode appears to be corrupted. ext2fs_add_journal_inode() 1729will also save the backup information, so that new filesystems created 1730by mke2fs and filesystems that have journals added via tune2fs will 1731also have journal location written to the superblock as well. 1732Debugfs's logdump command has been enhanced so that it can use the 1733journal information in the superblock. 1734 1735E2fsck will now update all superblocks when moving the journal inode. 1736 1737Shrink the size of the e2fsck executable by moving some initialized 1738variables to the BSS segment. 1739 1740E2fsck will avoid printing the ^A and ^B characters which bracket the 1741progress bar when stdout and stdin are a tty device instead of a pipe 1742to another program. (Addresses Debian bug #204137) 1743 1744Debugfs's mkdir command will automatically expand the directory if 1745necessary. (Addresses Debian Bug: #217892) 1746 1747Fixed a bug in debugfs so that copying a file from /dev/null uses the 1748correct mode bits. (Addresses Debian Bug: #217456) 1749 1750If the environment variables DEBUFS_PAGER and PAGER are not set, 1751debugfs now searches for the appropriate pager to use, beginning with 1752/usr/bin/pager, and then falling back to 'more' and 'less'. 1753(Addresses Debian bug #221977) 1754 1755Debugfs will now support 2.6 device numbers where the major or minor 1756number may be larger than 255. (Addresses Sourceforge bug #865289) 1757 1758Fix debugging printf in resize2fs. (Addresses Debian Bug #271605) 1759 1760Chattr now stops processing options when it sees '--'. (Addresses 1761Debian bug #225188) 1762 1763Fix regression tests so they work correctly when e2fsprogs is compiled 1764with configure --disable-htree. 1765 1766Fix bug in uuid library when there is no network card and the library 1767is generating a time-based uuid. The random MAC address was not 1768correctly generated to be a multicast address. 1769 1770Add compile_et extensions from Heimdall that were missed the first time 1771around. 1772 1773Fix bug in badblocks when using O_DIRECT; we need to make sure that 1774we're reading from an offset which is page aligned. For read-only and 1775read-write tests, we try to recover after an error so that we can 1776continue reading on page-aligned boundaries. (Addresses Debian Bug 1777#203713) 1778 1779Badblocks now checks 64 blocks at a time instead of 16. (Addresses 1780Debian bug #232240) 1781 1782Updated and clarified various man pages. (Addresses Debian Bug 1783#206845, #222606, #214920, #232406) 1784 1785Updated and fixed translations. (Addresses Debian bugs #200086, #214633) 1786 1787Fixed various Debian packaging issues (see debian/changelog). 1788 1789Programmer's notes: 1790------------------- 1791 1792Fixed a build problem so that e2fsprogs would compile with the 1793--enable-profile option to configure selected. (Addresses Sourceforge 1794bug #811408) 1795 1796Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat 1797Bugzilla Bug #112448) 1798 1799Centralize code which calculates the location of the superblock 1800and block group descriptors so that it is in a single library routine. 1801 1802Added two new functions, ext2fs_file_open2() and 1803ext2fs_inode_io_intern2() which take a pointer to an inode structure. 1804 1805Fix compile_et to output the correct prototype for 1806initialize_xxx_err_table_r() in the header file. (Addresses Debian 1807bug #204332) 1808 1809In the lib/et makefile, make sure com_err.info is deleted on "make clean". 1810 1811Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if 1812present. This is for when we try stuffing an int into void * pointer. 1813 1814Fix type-punning which can cause gcc 3.x to miscompile code by getting 1815confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(), 1816and ext2fs_resize_mem() all now take a 'void *' instead of a 'void 1817**'. The EVMS code uses an ugly union approach since we don't want to 1818modify the EVMS interfaces. 1819 1820Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to 1821aid build process on systems can use invoke GNU make as "gmake". 1822 1823Added regression testing for mke2fs. 1824 1825Fixed gcc -Wall nitpicks. 1826 1827Fixed various compiler warnings. 1828 1829Add portability fixes for FreeBSD and for using fsctl under Darwin to 1830support ext2 ioctl's. 1831 1832 1833E2fsprogs 1.34 (July 25, 2003) 1834=============================== 1835 1836Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in 1837a tight loop while waiting for a child fsck to exit in some cases. 1838This burns CPU times which slows down the low-level filesystem check. 1839 1840Added code to mke2fs to assure that the default block size for a 1841filesystem is at least as big as the sector size of the device, if it 1842can be determined. 1843 1844Changed mke2fs and resize2fs to round the default size of a filesystem 1845to be an even multiple of the VM pagesize in order to avoid a Linux 1846kernel bug introduced when the storage of the buffer cache was moved 1847into the page cache. 1848 1849Mke2fs will warn the user when creating a filesystem with journaling 1850and a blocksize greater than 4096. (Addresses Debian bug #193773) 1851 1852Fixed a bug in resize2fs which caused it to fail on filesystems with a 1853non-empty bad block list. Resize2fs now discards any blocks on the 1854badblock list which are no longer part of the filesystem as the result 1855of a filesystem shrink. (Note: this means that shrinking and then 1856enlarging a filesystem is no longer a reversible operation; 1857information about bad blocks in the part of the filesystem which is to 1858be chopped off will be lost.) 1859 1860Changed resize2fs so the user can use prefixes to specify the units of 1861the new filesystem size (sectors, kilobytes, megabytes, or gigabytes), 1862and to make the error and informational messages explicitly display 1863the blocksize used by the filesystem, in order to avoid confusion. 1864(Addresses Debian bug: #189814) 1865 1866Added a new debugfs command, dump_unused, which dumps the contents of 1867all unused blocks to stdout. (Useful as an emergency try-to-find 1868deleted data command.) 1869 1870Added a new debugfs command, imap, which prints the location of a 1871specified inode in the inode table. 1872 1873Fixed a bug in the badblocks program which caused it to use one bit of 1874randomness in its non-destructive read/write test, instead of using a 1875full 8 bits of randomness. 1876 1877Added a new option (-t) to badblocks, which allows the user to control 1878the test pattern(s) used when checking a disk. 1879 1880The blkid probe function now more correctly detects UDF filesystems. 1881 1882Fixed a bug in the blkid library which caused it to not update its 1883cache if a filesystem changes from having a label to not having a 1884label. 1885 1886Fixed a bug in the blkid library wihch could avoid an infinite loop 1887in blkid_find_dev_with_tag() if /proc is not mounted and there the 1888/etc/blkid.tab file has not yet been created. 1889 1890Fixed the badblocks program so that the destructive read/write test 1891honors the -c option, and to use O_DIRECT when possible to avoid 1892thrashing the system block buffer cache. 1893 1894Fixed various NLS issues. 1895 - Added Czech and Swedish translations 1896 - Removed testing NYC translation 1897 - Fixed NLS support for message abbrevations in e2fsck 1898 - Remove de-utf.po, since we shouldn't have two versions using different 1899 charset encodings. 1900 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to 1901 simplify the statistics reporting in e2fsck. 1902 1903Changed configure.in so that its defaults for *BSD systems no longer 1904build an fsck wrapper, and not to install in /usr/local by default. 1905 1906Fixed some minor spelling errors/typo's in e2fsck and the configure 1907script. 1908 1909Fixed various Debian packaging issues (see debian/changelog). 1910 1911Updated and clarified man pages. (Addresses Debian Bug #195616) 1912 1913Programmer's notes: 1914------------------- 1915 1916Fix gcc -Wall nitpicks. 1917 1918Updated gettext implementation used by e2fsprogs to 0.11.5, and enable 1919NLS support by default. (Added partial workaround for gettext/Darwin 1920incompatibility problems.) 1921 1922Added full MIT KRB5 and Himdall compaibility support to the com_err 1923library and the compile_et program. (Addresses Debian bug #191900) 1924 1925Added the blkid_known_fstype() function to the blkid library, which 1926returns true if it is passed a filesystem type which is recognized by 1927the blkid probing functions. 1928 1929Improved the documentation for the blkid library. 1930 1931Added the ext2fs_get_device_sectsize() function the the ext2fs library, which 1932returns the hardware sector size of a device, if it is available. 1933 1934Added a dependency in the blkid library's .so file to the uuid 1935library, since the former uses the latter. (Addresses Debian bug 1936#194094) 1937 1938Added --with-diet-libc and --disable-evms to the configure script. 1939 1940Fixed a minor memory leak in the badblocks program. 1941 1942Fixed a portability problem in tune2fs --- not all systems have strptime(). 1943 1944Fixed a portability problem in debugfs with the use of getopt() more 1945than once. Old-style BSD, new-style BSD, and Linux C libraries all do 1946things differently. 1947 1948Add support Windows support to ext2fs_get_device_size(). 1949 1950Added (normally disabled) debugging code to the Unix I/O manager which 1951causes it to disable all userspace caching if the NO_IO_CACHE is 1952defined. 1953 1954Changed the test I/O manager so it can always be linked into e2fsck, 1955mke2fs, and tune2fs if enabled via --enable-test-io-debug to the 1956configure script. The test I/O manager will only print any debugging 1957information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment 1958variables are set, which specifies which I/O operations are logged and 1959a block number to watch, respectively. The log messages are sent to 1960stderr by default, unless a filename is specified via the 1961TEST_IO_LOGFILE environment variable. 1962 1963 1964E2fsprogs 1.33 (April 21, 2003) 1965=============================== 1966 1967Added a new utility program, logsave, which captures the output of a 1968command in a log file, even if the containing directory hasn't been 1969mounted yet (in which case the it saves the output in memory until it 1970can write out the logfile). This is useful for capturing the 1971output of fsck during the boot sequence. 1972 1973Fixed some portability problems that were causing problems under 1974the Cygwin32 environment. 1975 1976Mke2fs now interprets a negative number to the -b option as a minimum 1977block size. 1978 1979Fixed a bug in mke2fs which was incorrectly checking the argument to 1980the -g option if the default block size was used. (Addresses Debian 1981bug #188319) 1982 1983Fsck now explicitly ignores tmpfs and devpts, and it will complain if 1984it can not find filesystem checkers for jfs, reseirfs, and xfs. 1985 1986E2fsck now updates the global free block and inode counters from the 1987block group specific counters quietly. This is needed for an 1988experimental patch which eliminates locking the entire filesystem when 1989allocating blocks or inodes; if the filesystem is not unmounted 1990cleanly, the global counts may not be accurate. 1991 1992Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS 19932.0 is not yet supported; this only pulled in the bug fixes: fixed 1994possible hangs caused by bugs in calling waitpid, and not setting the 1995pipe to non-blocking mode; also fixed a file descriptor leak; made 1996sure all functions call log entry/exit functions.) 1997 1998Badblocks now flushes its output file as bad blocks are discovered. 1999 2000The uuid library is now more paranoid about assuming the correctness 2001of the /dev/random device; it mixes in a stream of bytes from 2002random/srandom, just in case. 2003 2004Update Debian files to reflect the fact that I am now the Debian 2005maintainer of e2fsprogs. Other various Debian-specific packaging 2006cleanups. 2007 2008Move the source tarball generation functions from the top-level 2009makefile to the util/gen-tarball script. 2010 2011Updated the Turkish .po translation file. 2012 2013Added Heimdal and MIT krb5 extensions to the com_err library to make 2014it more compatible with com_err libraries from those distributions. 2015 2016Changed dumpe2fs to always display the superblock fields relating to 2017the journalling and/or directory indexing feature even if those 2018features are not enabled. 2019 2020Updated and clarify copyright statement vis-a-vis alpha releases of 2021e2fsprogs. 2022 2023The ss library will now try to dynamically link to the readline 2024library and use it if it is present in the system. This means that 2025the debugfs program now has line editing and history features. The 2026SS_READLINE_PATH environment variable is used to find a readline or 2027readline-compatible library. 2028 2029E2fsck now finds most duplicate filenames (all when rebuilding all 2030directories via the -D option) and offers to delete or rename 2031duplicate filenames/directory entries. (Addresses Debian Bug #176814). 2032 2033Fix bug in e2image. When writing out a raw image file, include data 2034blocks from symlinks that do not store the symlink within the inode. 2035 2036Fix bug in resize2fs which incorrectly moved the block and inode 2037bitmaps for sparse superblock filesystems and incorrectly marked 2038blocks as in use. (Addresses Debian bug #174766) 2039 2040Added a new shared library, the blkid library, which efficiently 2041allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL 2042and UUID filesystem specifiers without needing to search all of the 2043devices in the system. Instead, the device is looked up in a cache 2044file, and then verified to make sure the blkid cache is correct. 2045 2046Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for 2047the device name, using the blkid library. (Addresses Debian bugs 2048#166048, #179671) 2049 2050Fsck now supports backslash escapes in /etc/fstab so that \040 can be 2051used for spaces in device labels. 2052 2053Removed 32-bit limitations for debugfs's dump command. 2054 2055If the user specifies a large number of inodes, Mke2fs will 2056automatically adjust the number of blocks per group to find a valid 2057set of filesystem parameters. 2058 2059Add workaround to detect broken MD devices where when some of the 2060underlying devices are marked read-only, writes to the MD device are 2061silently dropped. E2fsck will detect if there is an attempt to run 2062the journal twice, and abort with an error if this is the case. 2063(Addresses IBM Bugzilla bug #1226) 2064 2065E2fsck will print an error if more than one of the -p/-a, -n or -y 2066options are specified. 2067 2068E2fsck will fix HTREE corruptions in preen mode, without stopping the 2069boot process. This is needed because the 2.4 ext2 filesystem 2070accidentally had the INDEX_FL backwards compatibility code removed. 2071 2072Mke2fs no longer creates filesystems with the dir_index flag set by 2073default; the user has to specifically request it. 2074 2075Update and clarified various man pages. (Addresses Debian bugs 2076#173612, #175233, #175113, and #170497, #185945, #188318) 2077 2078Created man page for the mk_cmds program (from the libss library). 2079 2080Programmer's notes: 2081------------------- 2082 2083Fix various gcc -Wall nits. 2084 2085Fixed a lot of portability problems that caused e2fsprogs not to build 2086successfully under Solaris and Apple/Darwin. 2087 2088Fixed a Makefile dependency to allow building e2fsprogs using parallel 2089make jobs. 2090 2091Changes to create a subset distribution which consists only of the 2092et, ss, uuid, and blkid libraries. The configure script and top-level 2093makefile were changed to support working with a subset distribution. 2094 2095Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not 2096actually used, and might people who are looking for 2097EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use. 2098 2099Updated debian files to fix a number of Lintian warnings. 2100 2101Updated config.guess and config.sub with newer versions from the FSF. 2102 2103Removed unnecessary libraries from being linked into the fsck, lsattr, 2104chattr, and blkid executables. 2105 2106E2fsprogs 1.32 (Nomvember 9, 2002) 2107================================== 2108 2109Fixed a bug in the Unix I/O routines which caused needless writebacks 2110of clean blocks from the unix_io cache (they were erroneously marked 2111as being dirty, so they were getting written back to disk before 2112getting evicted from the disk cache). This was harmless, but it 2113significantly slowed down e2fsck. 2114 2115Made some other minor optimizations to the Unix I/O routines to save a 2116small amount of CPU time. 2117 2118Updated internationalization files. 2119 2120 2121E2fsprogs 1.31 (Nomvember 8, 2002) 2122================================== 2123 2124Update EVMS ext2fsim plugin with EVMS 1.2. (We still support 2125compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error 2126handling for child process that die unexpectly. Add a hack to force 2127mkfs to create filesystems that won't cause problems with hardware 2128that has 2k or 4k minimum blocksize requirements. Read from child 2129processes in non-blocking mode, so that the GUI continues to update. 2130 2131Fix e2fsck so that it returns the appropriate exit code when the root 2132filesystem has been changed, so that system's rc scripts will be told that 2133the system needs to be rebooted. 2134 2135Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag 2136was set, some of the descriptor blocks that should have been written 2137out were getting skipped. 2138 2139Changed e2fsck to force out changes to the backup copies of the 2140superblock and block group descriptors when important changes are made 2141to those data structures. 2142 2143Fix a bug where e2fsck could erroneously mark a filesystem as being 2144clean if a check of dirty filesystem is interrupted with a ^C. (Bug 2145introduced in e2fsprogs 1.28.) 2146 2147If journal debuging is enabled using --enable-jbd-debug, the debugging 2148level is now set via the E2FSCK_JBD_DEBUG environment variable. 2149 2150If byteswapping support is disabled using configure --disable-swapfs, 2151skip the tests which depend on byte-swapping, so that "make check" 2152won't bomb out. 2153 2154Lshattr will now display the indexed directory flag. Also, some of 2155the more esoteric compression flags are supressed unless compression 2156support has been enabled. 2157 2158Update man pages. 2159 2160 2161E2fsprogs 1.30 (October 31, 2002) 2162================================= 2163 2164When resizing a filesystem, and inodes need to moved, resize2fs will 2165update the inode's ctime field, and the mtime field of the containing 2166directories, so that incremental backups using dump/restore will work 2167correctly. 2168 2169In order to avoid spurious errors, e2fsck wil check the last 2170superblock write time to determine whether or not it can safely use 2171the LOW_DTIME checks to determine if there are inodes on the orphan 2172inode linked list that had somehow gotten disconnected. (Addresses 2173Sourceforge bug #620980) 2174 2175Partition in /proc/partitions that being with the string "lvm" are 2176considered real partitions even if they do not end with a number. 2177 2178Fixed a bug in the the uuid generation function, where if /dev/urandom 2179is not present, but /dev/random is, and there isn't sufficient 2180entropy, the get_random_byte function could spin a loop forever. 2181 2182E2fsck, mke2fs, etc. will now reliably notice when image files are 2183mounted using the loopback interface. (Addresses Sourceforge bug 2184#619119) 2185 2186When flushing buffers (as is done by badblocks, for example) check to 2187see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the 2188FDFLUSH ioctl which causes the MD device driver which causes confusing 2189syslog messages about obselete ioctl messages. (Addresses Sourceforge 2190bug #545832). 2191 2192Debugfs's write command now checks to see if the destination filename 2193exists before creating it. (Addresses Sourceforge bug #478195.) 2194 2195When installing man pages, search for compressed man pages using all 2196commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.) 2197 2198Fixed a bug in fsck where multiple filesystems specified on the 2199command were not being checked in parallel due to a logic bug 2200introduced to support the FSCK_MAX_INST environment variable. 2201 2202We have added a new superblock field, s_mkfs_time, which indicates 2203when a filesystem was created. It is set via mke2fs, and printed out 2204by dumpe2fs, but is not actually touched by the kernel. 2205 2206Dumpe2fs has been made more robust by not aborting if there is an 2207error reading the block/inode bitmaps; instead it will still print out 2208the location of the block/inode bitmaps and inode table. 2209 2210Add support for the an alternative block group descriptor layout which 2211allows for on-line resizing without needing to prepare the filesystem 2212in advance. (This is the incomat feature flag meta_bg.) 2213 2214Add support for storing default mount options in the superblock, so 2215that the filesystem can be mounted with specific mount options without 2216needing to specify them on the mount command line or in the /etc/fstab 2217file. 2218 2219Add support for a new inode flag, which is to be used for indicating 2220the top of directory hierarchies for the Orlov block allocator. 2221 2222Fix e2fsck so that if it creates the lost+found directory, it does so 2223with the more apporpriate permissions of 0700. Also change 2224mklost+found so that it also creates the directory 0700. 2225 2226Fixed format bug in e2fsck if NLS is in use. 2227 2228Add a German translation for e2fsprogs's NLS support. 2229 2230Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at 2231the beginning of the inode table. This won't matter much, since if 2232there is a bad block at the beginning of the inode table, the root 2233directory won't be available. But at least e2fsck won't crash in this 2234case. 2235 2236Fixed endian problems in the htree code for e2fsck and debugfs. 2237 2238When byte-swapping a filesystem on a PPC architecture, byte-swap the 2239bitmaps since the historical big-endian ext2 variant had byte-swapped 2240bitmaps, and the ext2fs library assumes this. This fixes the 2241regression test suite on PPC machines. 2242 2243Fix e2image so that it handles a bad block in the inode table 2244appropriately. 2245 2246E2fsck now uses a more sophisticated algorithm to salvage corrupted 2247directories that recovers more information in the corrupted directory 2248block. 2249 2250E2fsck now performs additional consistency checks on indexed (HTREE) 2251directories. 2252 2253Fix bug where efsck might get confused about whether a completely 2254empty directory block is an empty leaf block or an interior htree 2255node. This could cause e2fsck to get confused into think that a valid 2256indexed directory was corrupted. 2257 2258E2fsck no longer creates an empty directory entry at the end of a 2259directory block when optimizing a directory. This would cause some 2260earlier versions of the dxdir kernel code to corrupt the directory 2261when attempting to split a node containing an empty directory entry. 2262 2263E2fsck could sometimes in rare circumstances leave the indexed flag 2264set after a small directory was optimized by compressing it instead of 2265indexing it. (This should never happen in real life, since 2266directories that small wouldn't have been indexed, but better safe 2267than sorry.) 2268 2269E2fsck now only updates the master superblock in all cases. This 2270slightly shortens its run time. 2271 2272Ext2ed can deal with directory entries of length 0; previously it 2273would get stuck in an infinite loop. 2274 2275Fsck now has support for reiserfs volumes when parsing LABEL= and UUID= 2276specifiers. (Sourceforge patch #613447) 2277 2278Badblocks will now work correctly on read-only devices such as 2279CD-ROM's. (Sourceforge patch #600451) 2280 2281Updated and clarified man pages. (Addresses Debian bug #167108) 2282 2283 2284E2fsprogs 1.29 (September 24, 2002) 2285=================================== 2286 2287Fixed a bug in e2fsck which could corrupt a directory when optimizing 2288it (via the -D option) or rebuiliding the hash tree index with a 1 in 2289512 probability, due to a fence post error. 2290 2291Fixed a bug in the LVM support code which caused LABEL='xxx' not to 2292work correctly. 2293 2294Mke2fs now enables the directory indexing flag by default. (Since 2295this is a compatible feature flag, it's safe to do so.) 2296 2297Tune2fs will support setting the directory indexing feature flag. It 2298will automatically set up the default hash algorithm and hash seed 2299fields in the superblock. 2300 2301If the bone-headed user enters the root filesystem twice in 2302/etc/fstab, the -R option which skips the root filesystem will skip 2303all of them. (Addresses Debian bug #159423). Note! This is not a 2304precedent for dealing intelligently with any other kind of doubled 2305entry in /etc/fstab! 2306 2307 2308Programmer's notes: 2309------------------- 2310 2311Removed perror declaration in lib/et/internal.h. All modern systems 2312can be expected to define perror() these days. Besides, the lib/et 2313code wasn't using perror at all anyway. :-) 2314 2315 2316E2fsprogs 1.28 (August 31, 2002) 2317================================ 2318 2319Add support for the Hashed-Tree Directory Indexing to e2fsck. Support 2320for setting the htree flag is not included yet, although it can be 2321manually turned on via the debugfs program. 2322 2323Clarified e2fsck error message which is printed when it cannot find 2324sufficient contiguous block when relcating filesystem metadata. 2325 2326Added support for building an EVMS plugin module for ext2/3. This 2327module is substantially the same as the EVMS module shipping with EVMS 23281.1, with one or two bugfixes. E2fsprogs can also build this plugin 2329for use with EVMS 1.0 (which did not include the ext2 plugin module), 2330if the configure --enable-old-evms flag is given. 2331 2332Fsck will search through EVMS volumes when trying to resolve 2333filesystem specifications such as LABEL=xxx or UUID=xxx. 2334 2335Added a new utility program, /sbin/findfs, which will return 2336filesystem specifications such as LABEL=xxx or UUID=xxx, and prints 2337the device name. 2338 2339Update and clarified various man pages. (addresses Debian Bug #145044, 2340#146437, #131350, #151990, #144621, #141938) 2341 2342If there are no filesystems specified on fsck's command line, fsck now 2343treat that as if the -As options were given. Previously it would 2344simply do nothing. (Addresses Debian Bug #153102) 2345 2346Mke2fs no longer treats a failure to be able to clear the MD signature 2347at the end of the filesystem as a fatal error. (Addresses Debian Bug 2348#155007) 2349 2350The e2p library functions (which are used by lsattr and chattr) now 2351double check to make sure the file is a regular file or directory 2352before attempting to use the ext2 ioctls. Some device drivers 2353unfortunately respond to the ext2 ioctl's with unknown behaviour. 2354(Addresses Debian Bug #152029). 2355 2356The extended attribute handling has been updated to correspond with 2357the latest V2 bestbits ACL code. 2358 2359Fixed bug in e2fsck which caused it to not clear the dtime field when 2360processing truncated inodes on the orphan list. This could cause data 2361loss(!) if a filesystem is rebooted before a truncate has been 2362committed. 2363 2364E2fsck now uses red/black trees in pass1b, which removes some O(n**2) 2365algorithms. This makes e2fsck much faster in the case of severely 2366corrupted filesystems where a large number of blocks are claimed by a 2367large number of inodes. (Thanks to the 2.5 IDE device driver for 2368inspiring this work.) 2369 2370Resize2fs has been significantly sped up when shrinking and expanding 2371a filesystem by a very small number of blocks (for example, when EVMS 2372is converting a partition to be an EVMS legacy volume). 2373 2374Added a new option to e2fsck, -D, which will optimize or compress all 2375of the directories in the filesystem. 2376 2377E2fsck now catches SIGINT and SIGTERM to make sure it will can 2378properly clean up and only exit at safe points. Fsck will pass 2379SIGINT/SIGTERM to its child processes, and wait until they have all 2380exited before it exits. 2381 2382The uuid parsing code in the uuid library now properly complains when 2383an illegally formated uuid is presented to it. (Addresses Debian bug 2384#152891) 2385 2386Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10 2387and 2.4.17, since the workaround can cause problems when using a 2.4 2388kernel with an old version of glibc built with the 2.2 headers. 2389 2390Fixed a bug in mke2fs where it wasn't properly clearing the initial 2391superblock used by other filesystems. (Addresses Debian bug #147256.) 2392 2393Added support for the synchronous directory feature written by Andrew 2394Morton. 2395 2396The debugfs program can delete directories using the rmdir command. 2397 2398Add support for 8k and 16k filesystems (for systems with page sizes 2399that are greater or equal to 8k or 16k, respectively). Note that 2400these filesystems can not be mounted on x86 systems, or other systems 2401with only 4k page sizes, due to limitations in the current Linux VM 2402code. 2403 2404Resize2fs requires that the filesystem state be valid and have no 2405errors; otherwise, e2fsck -f must be run first. (Previously it simply 2406required that the last fsck time be greater than the last mount time.) 2407 2408Configure now defaults the man pages directory to /usr/share/man on 2409Linux systems. 2410 2411E2fsck now offers to truncate inodes which contain too many blocks (so 2412that i_blocks would overflow. Also fixed handling of large sparse 2413files. 2414 2415E2fsck now more completely checks for symlink validity, including 2416requiring NULL termination and length checks. 2417 2418E2fsck will offer to try forcing a disk write to remap a bad block 2419after finding a read error when reading a filesystem metadata block. 2420 2421Fixed a bug in debugfs which caused the -b and -s options to crash 2422debugfs, as well as breaking the testb, setb, and clearb functions. 2423 2424Added a bmap command to debugfs which calculates the logical to 2425physical block mapping for a particular inode. 2426 2427Fixed a bug in code which checked to see if a device was mounted which 2428sometimes (rarely) failed in the case of a plain file. 2429 2430Fixed a bug in resize2fs where when it reported an error, it would 2431print a message erroneously indicating that the filesystem had been 2432resized before it aborted. 2433 2434When resizing a plain file which is smaller than the requested size, 2435resize2fs will attempt to extended the file so that programs like 2436e2fsck will not complain that the file is too small. 2437 2438Resize2fs will print the actual new size of the filesystem when it is 2439finished resizing. 2440 2441Fixed a bug in debugfs where "ls -l" would report incorrectl file type 2442information on big-endian systems. 2443 2444 2445Programmer's notes: 2446------------------- 2447 2448Fixed collisions with C++ reserved words. 2449 2450Added portability fixes for building e2fsprogs on the HURD and AIX. 2451 2452Added the ext2ed program for creation of test cases. (ext2ed has many 2453limitations and bugs which make it unsuitable for production use.) 2454 2455The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new 2456flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the 2457name_len field is byte swampped on big-endian machines, since in the 2458V2 structure, name_len is a char field which is doesn't need to be 2459byte swapped --- except if an old-style kernel had byte-swapped the 2460name_len field as part of the V1 structure. 2461 2462 2463E2fsprogs 1.27 (March 8, 2002) 2464============================== 2465 2466The warning messages for mke2fs now go to standard error. 2467 2468Fixed to make sure "make check" runs all of the test programs with 2469LD_LIBRARY_PATH set, so that we test the libraries in the build tree. 2470 2471The mke2fs program checks the boot sector for the BSD disk label, and 2472avoids erasing it if it is there. 2473 2474Fixed a bug in e2fsck which caused it to core dump if the journal 2475inode was missing when it was supposed to be there. 2476 2477E2fsck now prints ranges in pass 5 when printing deltas for the block 2478and inode bitmaps. 2479 2480Debugfs's "ls -l" command now will print out the file type information 2481in the directory entry. 2482 2483Create man pages and hard links for fsck.ext3 and mkfs.ext3. If 2484mke2fs is invoked as mkfs.ext3, create the filesystem with a journal. 2485 2486Debugfs can now examine the experimental directory indexing 2487information. 2488 2489Fixed bug in debugfs which caused it to core dump if modify_inode is 2490called without an open filesystem. 2491 2492The debugfs lsdel command now runs its output through a pager first. 2493 2494When installing manual pages, remove the compressed manual pages first. 2495 2496Synchronized with Debian's packaging information for e2fsprogs-1.26-1. 2497 2498Fix the 2.4 resource limitation workaround introduced in 1.26 which 2499actually broke things on mips32, sparc32, and Alpha platforms. 2500 2501Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made 2502(which is required by the newer libintl libraries). 2503 2504Programmer's notes: 2505------------------- 2506 2507Fixed various gcc -Wall complaints. 2508 2509Fixed a few memory leaks in the e2fsck journaling code, and in the 2510ismounted code checking for a swap device. 2511 2512Add new inode I/O abstraction interface which exports an inode as 2513an I/O object. 2514 2515Exported ext2_file_flush as a public interface. 2516 2517In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer. 2518 2519Lots of small random portability fixes to make e2fsprogs build under 2520AIX --- even without the 5L compatibility toolkit, and even using the 2521uber-crippled AIX native C compiler. 2522 2523 2524E2fsprogs 1.26 (February 3, 2002) 2525================================= 2526 2527Dumpe2fs will keep going now if the bad block inode can't be read. 2528(Previously it stopped with a fatal error.) 2529 2530E2fsck will now give an opportunity to run the journal even if the 2531recovery flag is not set. This is the default behaviour if e2fsck is 2532using a backup superblock, since the needs_recovery flag will never be 2533set in the backup superblock copies. 2534 2535E2fsck now automatically finds the backup superblock/group descriptors 2536even when the primary superblock is completely destroyed for 2k and 4k 2537filesystems. (Previously it just guessed/assumed that we were dealing 2538with a 1k filesystem in that case, and users had to manually specify 2539the backup superblock number.) 2540 2541Fixed a bug in e2fsck where it dereferences a null pointer when there 2542is a problem opening a filesystem in preen mode. 2543 2544E2fsck now handles external journals correctly; previously it trashed 2545the external journal device if the journal needed to be replayed. 2546 2547Work around ulimit incompatibility problem caused by recent 2.4 2548kernels; the unix IO module will automatically try to set any resource 2549limits to be infinite on startup. 2550 2551Fixed a bug in e2fsck where it wasn't allocating a new block or inode 2552bitmap if it wasn't present and the blocksize was 2k or 4k. 2553 (Addresses Debian Bug #116975) 2554 2555E2fsck will check and fix botched ext3 V1 to V2 superblock updates by 2556clearing the new V2 fields if they do not make sense or if the ext3 2557superblock is version 1 superblock. 2558 2559E2fsck will automatically relocate the ext3 journal from a visible 2560file (i.e., /.journal) to an hidden inode if the filesystem has been 2561opened read/write. This allows the users to add a journal while the 2562filesystem is mounted, but the next time the system is rebooted, the 2563journal file will disappear. This avoids problems with backups, 2564stupid operators with superuser bits, etc. 2565 2566Fix a bug in fsck where it would not support a filesystem type of 2567"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx. 2568 2569Fsck now supports fstab entries of the form "ext3,ext2". It will also 2570automatically identify reiserfs filesystems. 2571 2572The number of processes spawned by fsck can now be limited using the 2573FSCK_MAX_INST environment variable. 2574 2575Fsck now searchs the LVM proc hierarchy to find logical volumes which 2576should be searched for UUID and label information. 2577 2578Work around a bug in 2.4.10+ kernels by trying to unset the filesize 2579limit if at all possible, when opening a block device. (The filesize 2580limit shouldn't be applied against writes to a block device.) 2581 2582In mke2fs and e2fsck, specifying the -c option twice will now do 2583a read/write test on the disk. Update the man pages to encourage 2584using the -c option, and to discouraging running badblocks separately, 2585since users tend to forget to set the blocksize when running 2586badblocks. 2587 2588Mke2fs now automatically clears the immutable attribute on a 2589pre-existing .journal file left over from a previous failed attempt to 2590add a journal to an alreadyy-mounted filesystem. 2591 2592Fixed mke2fs's exit codes to consistently indicate when the mke2fs 2593operation failed. 2594 2595Mke2fs now creates the lost+found directory with permissions of 0700, 2596so that files that had previously lived in protected directory are 2597safe if they get dropped in lost+found and the system administrator 2598doesn't deal with immediately. (Addresses Debian #bug 118443) 2599 2600Mke2fs and e2fsck (and all programs that use the 2601ext2fs_check_if_mounted function) will now properly identify that a 2602device is mounted, even in cases where devfs has confused things with 2603multiple devices names with the same identity, or if a dim-witted 2604system administrator has done something stupid like creating device 2605file aliases in their home directory. Also now checks for swap devices 2606by using /proc/swaps. (Addresses Debian bug #106622) 2607 2608Added a new option (-T) to tune2fs which sets the time a filesystem 2609was last checked. 2610 2611Speed up e2image when creating sparse raw image files by optimizing 2612away excess lseek() system calls. 2613 2614Fix support of large (> 2GB) files when used as a filesystem in 2615mke2fs, tune2fs, debugfs, and findsuper. 2616 2617Debugfs's stat and icheck commands now properly deals with large (> 26182GB) files. 2619 2620Debugfs's set_super_value command now prints out the list of valid 2621superblock fields which can be set using the command. 2622 2623Debugfs's rm and kill_file command now updates the superblock free block 2624and inode counts, thus keeping the filesystem consistent. 2625 2626Debugfs's lsdel command now takes an optional argument which allows 2627the user to only see the most recently deleted files. 2628 2629A new command (undel) was added to debugfs which automates 2630undeleting a deleted inode and linking it back to a directory. 2631 2632Debugfs's ls command now takes a new option, -d, which lists 2633deleted directory entries. 2634 2635Debugfs's testb, freeb, setb, and find_free_block commands now take an 2636optional count argument. 2637 2638Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will 2639be used to signal that a particular inode should not be eligible for 2640tail-merging --- this is needed for programs like LILO. 2641 2642The findsuper (an unreleased, uninstalled utility program) has been 2643improved to add extra validity checks and to add a progress meter. 2644(It is still an unsupported program; the officially supported way to 2645recover from a trashed partition table is to use gpart; findsuper is 2646for wizards only. :-) 2647 2648Debugfs was fixed to compile with "configure --disable-swapfs". 2649 2650Cleaned up various manual pages. (Addresses Debian bug #119624, #120171) 2651 2652Added new translation file for Turkish. 2653 2654Programmer's notes: 2655------------------- 2656 2657Fix general gcc -Wall complaints. 2658 2659E2fsprogs (mostly) works with the dietlibc. 2660 2661The programming texinfo file has been expanded to include description 2662of additional libext2fs functions. (Still not compeltely done, but a 2663lot of the more important functions have been documented.) 2664 2665Added a umask structure to struct_ext2_filsys, which currently only 2666modifies the behaviour of ext2fs_mkdir(), but if we add any file 2667creation functions to libext2fs, we should also make sure they respect 2668the umask setting. 2669 2670The build-rpm script was fixed to be a bit more safe. 2671 2672The tests' Makefile now has a way of automating test case creation 2673for e2fsck, using "make testnew". 2674 2675Created a new function, ext2fs_dir_iterate2 which passes more 2676information to the callback function (identical to the one used by 2677ext2fs_dblist_dir_iterate). The directory iterator functions take a 2678new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted 2679directory entries. If the directory entry is deleted, the callback 2680function will be called with the entry paraemter set to 2681DIRENT_DELETED_FILE. 2682 2683Added new functions, ext2fs_inode_alloc_stats and 2684ext2fs_block_alloc_stats, which takes updates block/inode allocation 2685statistics in the bitmaps, block group descriptors, and superblock 2686when inodes or blocks are allocated or deallocated. 2687 2688 2689E2fsprogs 1.25 (September 20, 2001) 2690=================================== 2691 2692This is primarily a bug-fix release; no new features were added, but 2693there are a number of embarassing bug fixes and cleanups applied. 2694 2695Fix a bug mke2fs which causes stack garbage to be written to disk when 2696zapping disk sectors. (This bug could cause mke2fs to core dump for 2697some kernels, I suspect with security enhancement patches.) 2698 2699Remove unneeded #include of <linux/config.h> which was breaking 2700building e2fsprogs on the Hurd. (Addresses Debian bug #112414.) 2701 2702Updated tune2fs man page to reflect the fact that adding or removing a 2703journal doesn't require running e2fsck. 2704 2705Remove use of AC_REQUIRE from autoconf which had been used to prevent 2706AC_CANONICAL_HOST from being called twice; unfortunately this causes 2707recent autoconf to bomb out since they don't allow AC_REQUIRE to be 2708used outside of autoconf macros. Fortunately, it doesn't seem to be 2709necessary any more, anyway. 2710 2711E2fsck will now not fall back to an alternate superblock if the user 2712specifies the superblock location explicitly on the command-line. 2713This allows easier recovery from a situation where the primary 2714superblock and block groups are slightly corrupted, but the backup 2715superblocks are completely broken. 2716 2717Fix problem which caused compile_et and mk_cmds to blow up if 2718e2fsprogs was in a directory with a pathname that contained spaces. 2719 2720We are now more paranoid about checking the entry in /etc/mtab to make 2721sure the filesystem is really mounted, since some broken distributions 2722(read: Slackware) don't initialize /etc/mtab before checking non-root 2723filesystems. (Slackware also doesn't check the root filesystem 2724separately, and reboot if the root filesystem had changes applied to 2725it, which is dangerous and broken, but there's nothing I can do about 2726that.) 2727 2728Make UUID library C++ friendly by adding appropriate extern "C" 2729declarations and using const in the function declarations. 2730 2731Fix up the com_err texinfo file so that it can product a valid info 2732file (previously, it could only be used to generate paper 2733documentation using texinfo.tex). 2734 2735 2736E2fsprogs 1.24a (September 2, 2001) 2737=================================== 2738 2739Fix brown-paper bug in mke2fs which caused it to segfault when 2740printing the version string. 2741 2742 2743E2fsprogs 1.24 (August 30, 2001) 2744================================ 2745 2746Revert the BLKGETSIZE64 support, since for some distributions, this 2747ioctl has been used by an unofficial kernel patch to update the last 2748sector on the disk, and this was causing disk corruption problems as a 2749result. 2750 2751Mke2fs is now more careful about zapping swap space signatures and 2752other filesystem/raid superblock magic values so that programs like 2753mount who try to use hueristics to determine the filesystem type of a 2754partition are less likely to be confused. 2755 2756E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a 2757regular file (since Andreas Dilger's on-line resizing tools will set 2758its mode bits). 2759 2760Fixed some minor texinfo, man pages nits for spelling errors, 2761texinfo warnings, etc. (Addresses Debian bug #110621.) 2762 2763E2fsprogs program no longer print the filesystem version number 2764(i.e. 0.5b), since it only confuses people and doesn't serve any real 2765purpose. 2766 2767E2fsck will once again compile under libc5, since it will supply its 2768own version of strnlen if necesssary. 2769 2770mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers 2771when specifying the external journal device. tune2fs will also search 2772devices looking for the externla journal debice when removing. 2773 2774E2fsprogs 1.23 (August 15, 2001) 2775================================ 2776 2777Add initial support for extended attributes (EA); e2fsck will 2778correctly handle a filesystem with EA's and check the EA blocks for 2779corruptions. 2780 2781E2fsck's symlink sanity checking has been cleaned up. It now checks 2782the i_size value of fast symlinks, and checks for immutable flags 2783being set of symlinks, etc. 2784 2785E2fsck now offers to clear inodes which are special files that have a 2786non-zero i_blocks or i_size field. (The i_size field check was in the 2787previous version of the code, but due to a bug it didn't offer to 2788clear the inode unless i_size and i_size_high were both non-zero.) 2789 2790E2image can now create "raw" image files, which only contain the 2791filesystem metadata placed in a spare file so that e2fsck, dumpe2fs, 2792debugfs, etc., can be run directly on the raw image file. 2793 2794Add support for the 64-bit block device patches. 2795 2796Fixed bugs in creating external journals with a 1k blocksize. 2797 2798Add initial support for external journals (so long as the external 2799journal only supports a single filesystem) in e2fsck. 2800 2801Remove requirement for needing to run fsck on a filesystem after 2802removing a journal (either internal or external). 2803 2804The man pages now document how to create and manage external journals. 2805 2806Speed up the check of an ext3 filesystems by avoiding a needless flush 2807of all of the superblock and block group descriptors. 2808 2809Speed up creating an internal journal using tune2fs in the case where 2810the filesystem has a lot blocks already allocated. 2811 2812Tune2fs has been fixed to make sure that only error messages go to 2813stderr, and normal message go to stdout. (Addresses Debian bug #108555) 2814 2815Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will 2816now not set the sparse_super feature. (Addresses Debian bug #108165) 2817 2818Add support in fsck for the filesystem type "auto". 2819 2820Fsck -A will not try to interpret device names for filesystems which 2821have a pass number is 0. (Addresses Debian bug #106696). 2822 2823Fsck prints a warning message if now valid filesystems are passed to 2824it. (Addresses Debian Bug #107458.) 2825 2826E2fsck now gives an explicit warning if there filesystem still has 2827errors at the end of the run. (Addresses Debian bug #104502) 2828 2829E2fsck will set the EXT2_ERROR_FS flag if the journal superblock 2830reflects an error. E2fsck will also not run the orphan list if the 2831filesystem contains errors, since the orphan list might be corrupted. 2832 2833E2fsck now prints the number of large files when given the -v option. 2834 2835Fixed minor memory leaks in e2fsck. 2836 2837Some minor man pages updates. (Addresses Debian bug #30833, #108174) 2838 2839 2840E2fsprogs 1.22 (June 22, 2001) 2841============================== 2842 2843Fixed a bug in e2fsck's handling of orphan inodes which are special 2844files (i.e., block/character device files, named FIFO's, etc.). 2845 2846Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused 2847tune2fs to fail at adding a journal to a mounted filesystem. 2848 2849Fixed a few big-endian bugs in e2fsprogs 2850 * The directory block functions were accidentally reporting 2851 some directories as corrupted when they weren't. 2852 * If e2fsprogs is compiled --disable-swapfs, the C language 2853 equivalents weren't being included for big-endian platforms. 2854 (Fixes Debian bug #101686). 2855 2856Fixed a Hurd compilation problem. (Addresses Debian bug #101361) 2857 2858Programmer's notes: 2859------------------- 2860 2861Use platform independent method of defining the BLKFLSBUF and FDFLUSH 2862ioctls, and allow them to be defined for non-i386 platforms. 2863 2864The uuid.h header file is now protected against multiple inclusions. 2865 2866E2fsprogs is now being developed using BitKeeper. Changed the test 2867scripts to deal with BK's stripping CR characgters from text files, 2868and changed the top-level Makefile.in to avoid including BitKeeper 2869files when generating the source tarball. 2870 2871 2872E2fsprogs 1.21 (June 15, 2001) 2873============================== 2874 2875Added new configure flags which allow a subset e2fsprogs to be built; 2876this is most useful for boot floopies, since the resulting shared 2877libraries and programs are slimmed down by removing features that 2878aren't necessary for a boot floppy. The new flags that were added 2879are: --disable-swapfs, which removes support for byte swapping old 2880legacy PPC/68k filesystems, --disable-debugfs, which removes support 2881for debugfs from the libext2fs library, --disable-imager, which 2882removes support for the e2image program, and --disable-resizer, which 2883removes support for resize2fs. 2884 2885E2fsck now prints the number of mounts or days elapsed since the last 2886check when e2fsck is forced to check an otherwise clean filesystem. 2887 2888Tune2fs now prints an informative message about how often a filesystem 2889will be checked when adding a journal to the filesystem, to remind the 2890user that he/she may want to adjust those parameters using tune2fs 2891-c/-i. 2892 2893Worked around hurd brain-damage which causes e2fsck to sometimes 2894believe a filesystem is the root filesystem based on device numbers 2895(since Hurd doesn't have dev_t's, which is arguably a POSIX.1 2896violation). 2897 2898Fixed a bug introduced in 1.20 which caused e2fsck to abort with an 2899erroneous error with the -F option was specified. 2900 2901Fixed a ext3 recovery bug in the revoke handling; synchronized with 2902ext3 0.7a. 2903 2904Fixed two bugs in e2fsck's handling of dup block handling, dealing 2905with relatively uncommon edge cases: a directory with an indirect 2906block which is claimed by another file, and when the last inode in the 2907filesystem has blocks claimed by another file. 2908 2909E2fsck now checks to see if the i_size field of a fast symlink is too 2910big, and offers to clear the symlink if so. 2911 2912E2fsck now checks to see if i_size_high of special files is non-zero, 2913and offers to clear i_size_high. 2914 2915Fix e2fsck's handling of incompatible journal flags so that the user 2916has chance to abort, and then has the option to clear out the journal 2917entirely. (Addresses Debian bug #98527.) 2918 2919Fixed a bug in fsck which could cause it to core dump if a mix of 2920standard and non-standard device names are used in /etc/fstab. 2921(Debian bug #100559) 2922 2923Fixed a bug in debugfs which caused read errors when copying a file to 2924not be noticed. 2925 2926The debugfs set_super_value command can now modify the s_lastcheck field. 2927 2928Fixed a bug in lsattr and chattr which was accidentally introduced in 29291.20 to support > 2GB files; both lsattr and chattr wasn't reading 2930directories correctly because the change modified the layout of struct 2931dirent to be incompatible with the libe2p shared library. 2932 2933Cleaned up the mke2fs manual page and included a discussion about why 2934it's good to periodically check the filesystem even when journaling is 2935enabled. 2936 2937Programmer's notes: 2938------------------- 2939 2940Fix general gcc -Wall complaints. 2941 2942The types needed by the ext2 header files are now provided by 2943lib/ext2fs/ext2_types.h, instead of include/asm/types.h. 2944 2945Integers are now preferred to longs when trying to find a 32-bit type 2946in ext2_types.h. Also, if linux/types.h has already been defined, 2947don't try to redefine the types. 2948 2949Fixed make depend script so that it automatically corrects the 2950pathname cleanups performed by make -M, so I don't have to fix them up 2951by hand. 2952 2953Fixed the d_loaddump test case to be more robust, and not depend on 2954bash'isms. 2955 2956Removed debugfs's dependence on pread(), which was accidentally 2957intrudced in e2fsprogs 1.20 2958 2959Fixed a performance bug in the libext2fs's icount routine; the size 2960estimate of the icount array was incorrectly being calculated. 2961 2962Removed use of the badblocks compatibility functions in the e2fsprogs 2963programs. 2964 2965Added paranoia code which protects against strange cases where /etc 2966isn't on the root filesystem, or if /etc/mtab doesn't exist. 2967 2968The header file ext2_types.h is now installed. 2969 2970Autoconf is used to determine when we are on big-endian machines, 2971instead of doing run-time tests, to save a few bytes of code. 2972 2973The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap 2974functions are no longer inline functions, which saves space and 2975doesn't really cost any real performance. 2976 2977The ext2fs library no longer depends on the e2p library. (What need 2978there was of it --- namely, fsetflags, was coded in-line). 2979 2980Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even 2981when the user is stupid and tries compiling the package using "make 2982install" as root. 2983 2984Miscellaneous code cleanups: 2985 * Added missing files from Makefile.in's SRCS file, so that 2986 their dependencies would be properly calculated. 2987 * Removed redundant code 2988 * Fixed comments in code 2989 * Removed no-longer unneeded argsused #pragma. 2990 2991 2992E2fsprogs 1.20 (May 20, 2001) 2993============================= 2994 2995Add support for replaying the ext3 journal purely in user mode, 2996including handling the orphaned inode list. Used code contributed by 2997Andreas Dilger, with bug fixes and the orphaned inode handling done 2998by Theodore Ts'o. 2999 3000The mke2fs and tune2fs programs can create or modify a filesystem to 3001include an ext3 journal. Tune2fs also can be used to remove an ext3 3002journal from a filesystem. 3003 3004E2fsck will now check for the existence of a linked list of orphan 3005inodes in the superblock, and clear those inodes before starting the 3006rest of the filesystem check (but after the journal playback). 3007 3008E2fsck now validates the file descriptor passed to the -C option, 3009which saves against the completion bar getting written to an 3010unexpected location, such as the disk being checked. (Debian 3011bug/wishlist #55220) 3012 3013E2fsck will now bump the filesystem revision number from zero to one 3014if any of the compatibility bits are set. 3015 3016Fixed a bug where a badly corrupted directory on a big endian system 3017could cause e2fsck to die with a bus error. The 3018ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in 3019the ext2 library now does alignment sanity checks on the rec_len field 3020of the directory entry before using it. 3021 3022The ext2 library has been enhanced to make tune2fs safe to run on 3023mounted filesystems. (Users could usually get away with using tune2fs 3024on mounted filesystems before, but with the advent of ext3 and 3025journaling, it became important to make tune2fs was *really* safe for 3026use even when the filesystem being modified is mounted.) E2label is 3027now implemented by tune2fs using an argv[0] dispatch, so that e2label 3028is also now safe for use on mounted filesystems. 3029 3030Added a new program, e2image, which creates a backup of critical ext2 3031filesystem data structures. The generated image file can be examined 3032using dumpe2fs and debugfs. In the future, e2fsck will be able to use 3033the image file to help recover very badly damaged filesystems. 3034 3035Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files 3036no longer cause e2fsck to bomb out. Also treat files > 2GB as being 3037large file when deciding whether or not the filesystem has large files. 3038 3039Fixed lsattr and chattr so that they work correctly on large files. 3040(Fixes Debian bug #72690.) 3041 3042Removed limitation in get_device_size() which imposed a one terrabyte 3043filesystem limitation. (Most 2.2 kernels still have a signed int 3044problem which cause 1 TB block device limitation. Fortunately, the 3045kernel patches to fix this are much easier than fixing the 2TB 3046limitation in the kernel. :-) 3047 3048A max_mount_count of zero is now treated as if no mount count were 3049set. (Previously, no mount count was indicated by using -1, and a 3050mount count of zero caused e2fsck to always be run.) 3051 3052Mke2fs supports two new filesystem types largefile and largefile4. 3053 3054Mke2fs now adds some randomness in s_max_mount_count so that multiple 3055filesystems won't be all checked at the same time under normal 3056operations. 3057 3058Fixed bug in the progress bar printing code which could cause e2fsck 3059to core dump on an illegal filesystem. 3060 3061Fixed bug in fsck which could allow more than one instance of e2fsck 3062to be printing a progress bar. (Debian bug #65267) 3063 3064Fsck using a UUID or a LABEL specifier will work even if devfs is 3065compiled into the kernel and not mounted. If the pathnames in 3066/proc/partitions are incorrect, fsck will search /dev for the correct 3067device (using the new ext2fs_find_block_device library function). 3068Fsck now also checks the RAID devices first so that they are properly 3069found when they are in use. Support has also been added to support 3070additional IDE disks and the DAC 960 device names. (Debian bug #94159) 3071 3072Fixed a bug in fsck which caused it not deal properly with 16 3073byte long filesystem labels. 3074 3075Fsck's -t option has been made a lot more flexible. The semantics for 3076what happens if a comma-separated list to fsck has been regularized, 3077and it is now possible to filter what filesystems will get checked 3078based what is in the filesystem's fstab entry's option field. (Debian 3079bug #89483.) 3080 3081The dumpe2fs program can now print out the group description 3082information in hex, and also prints the location of the superblock and 3083block group descriptor for those block groups that have them. 3084 3085Mke2fs now clears the ext2 superblock before it starts creating a 3086filesystem, so that the superblock magic number is only written if the 3087filesystem creation process successfully completes. 3088 3089The debugfs program's stat command now pretty-prints the blocks used 3090by an inode so that it's more compact and informative. 3091 3092The debugfs stats command now uses the same libe2p code (which is used 3093by dumpe2fs) to print the superblock header information. This is more 3094complete, and it avoids a bit of code duplication. 3095 3096Added a new debugfs command, set_super_value (ssv) which allows the 3097user to set arbitrary superblock fields. 3098 3099Debugfs was extended to support inode numbers in hex (by prefixing 3100them with 0x), and so that modify_inode can set the inode generation 3101number. Also, there is now a new function command called logdump 3102which will dump an ext3 journal. 3103 3104Fixed a bug in debugfs so that quitting out of the pager doesn't kill 3105debugfs. 3106 3107Debugfs's dump command now stops immediately upon reporting a disk 3108read error. (Fixed a bug in ext2fs_file_read library routine which 3109caused debugfs not to stop.) (Debian bug #79163) 3110 3111On systems with /proc/mounts (mainly Linux systems), /proc/mounts is 3112checked before /etc/mtab is used, since /proc/mounts is more likely to 3113be accurate. 3114 3115Added portability fixes for Solaris and Linux/ia64. 3116 3117Various manual pages were clarified and cleaned up. (Fixed debian 3118bugs #63442, #67446, and #87216) 3119 3120 3121Programmer's notes: 3122------------------- 3123 3124The e2fsck message printer now supports %Iu and %Ig, which will print 3125out the inode's user and group owners, respectively. 3126 3127E2fsprogs now includes its own version of include/linux/ext2_fs.h, so 3128that no longer dependent on the system having the correct version of 3129the kernel header files. 3130 3131Added a new function to libext2, ext2fs_find_block_device(), which 3132searches the system (i.e., /dev, /devfs, /devices) for a pathname to a 3133device given its device number. 3134 3135Added a new function to libext2, ext2fs_sync_device, which centralizes 3136all of the places which might try to use the BLKFLSBUF or FDFLUSH 3137ioctls (and usually failing to define them since the system header 3138files don't usually do this for us, and we're trying to avoid usage of 3139kernel include files now). 3140 3141Added new utility programs in tests/progs: random_exercise and 3142hold_inode. They aren't built by default; they're useful for 3143exercising ext3 filesystem code. 3144 3145Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes 3146the filesystem close functions to only update the superblock, and to 3147not touch the block group descriptors. Needed by tune2fs when 3148modifying a mounted filesystem. 3149 3150Got rid of struct ext2fs_sb and replaced it with the standard struct 3151ext2_super_block from include/linux/ext2_fs.h. Note: this may break 3152source (but not binary) compatibility of some users of the ext2 3153library. Those applications should just simply do a global search and 3154replace of struct ext2fs_sb with struct ext2_super_block, and include 3155the new header file <ext2fs/ext2_fs.h> which defines it. 3156 3157The ino_t type has been renamed ext2_ino_t to protect applications 3158that attempt to compile -D_FILE_OFFSET_BITS=64, since this 3159inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an 3160unexpected ABI change. 3161 3162The Makefiles have been reworked so that "make check" can be run from 3163the top-level Makefile. 3164 3165Fix general gcc -Wall complaints and removed dead code. 3166 3167Remove use of NOARGS, because we assume everyone does ANSI C these 3168days. 3169 3170Added build-rpm script from sct. 3171 3172New functions ext2fs_image_{inode,super,bitmap}_{read,write} added 3173to support e2image. 3174 3175New function ext2fs_flush_icache which must be called if the 3176application program modifies the inode table blocks without going 3177through ext2fs_write_inode() interface. 3178 3179New ext2fs_check_mount_point() function, which will return the mount 3180point of a device if mounted. 3181 3182The io_channel abstraction now has an optional interface, 3183io_channel_write_range, which allows specific byte ranges to be 3184written. 3185 3186The unix_io IO channel now supports write-through caching, so that 3187journal creation is more efficient. 3188 3189Added x86 assembly language routines to support byte swapping, to 3190reduce executable size. 3191 3192Fixed bug in the utility program subst so that it's possible to 3193replace a substitution variable with a zero-length string. 3194 3195Fixed numbering e2fsck pass1 problem numbers; an extra zero had 3196slipped into some of the problem number. 3197 3198E2fsprogs 1.19 (July 13, 2000) 3199============================== 3200 3201Release the resize2fs program since the timeout before it could 3202be released under the GPL has finally expired. 3203 3204Add experimental support needed for the ext2 compression patches. 3205This requires compiling e2fsprogs with the --enable-compression flag 3206to the configure script. 3207 3208Added ext3 journalling support. E2fsck will run the journal (if 3209necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is 3210installed as a symlink to e2fsck. Fsck has been taught about ext3, 3211and treats it the same as ext2 in terms of the progress bar logic. 3212Dumpe2fs will display the superblock journaling information if the 3213filesystem has a journal. The ext2 library will now permit opening an 3214ext3 filesystem with the recovery flag set. This is necessary for 3215on-line dump's to work correctly, but there may be issues with this 3216working well since ext3 is much less agressive about syncing blocks to 3217the filesystem, since they're safe on the journal. 3218 3219Tune2fs and e2fsck have been changed to allow the mount_count check to 3220be disabled by setting max_mount_count to -1. (This was already 3221supported by the kernel.) 3222 3223Create a symbolic link for fsck.ext3, since the e2fsprogs utilities 3224are used for ext3 as well. 3225 3226Added internationalization support for e2fsprogs; must be enabled 3227by passing --enable-nls to configure. 3228 3229Always use the provided ext2fs header files to insulate ourselves from 3230kernel version changes. Which include files are used by e2fsprogs 3231have also been cleaned up to improve portability. 3232 3233Limit the number of times that e2fsck updates the progress bar so that 3234people who are booting using a 9600 baud console don't get swampped by 3235too many updates. 3236 3237Improved the loop detection algorithm in e2sck's pass #3 so that it is 3238much, much faster for large filesystems with a large number of 3239directories. 3240 3241The memory footprint for e2fsck is now slightly smaller than before. 3242 3243E2fsck now checks if special devices have a non-zero size, and offers 3244to clear the size field if it finds such an inode. 3245 3246E2fsck now checks if special devices have the append-only flag set, 3247and offers to clear the inode. 3248 3249E2fsck now properly handles some "should never fail" cases during a 3250bitmap copy in pass5. 3251 3252E2fsck now properly prints control characters in filenames as ^A .. ^Z. 3253 3254E2fsck now calculates the correct location of the backup superblock in 3255the case of filesystem blocksizes > 1k. 3256 3257Fixed a bug in e2fsck's calculation of the number of inodes_per_block 3258which normally didn't cause problems under most filesystem parameters, 3259but could cause a valid superblock to be rejected in extreme cases. 3260Other checks for validating superblock values were made more 3261stringent. 3262 3263Added non-destructive write testing to the badblocks program, courtesy 3264of David Beattie. The badblocks also now has an option to input the 3265current set of bad blocks, so that known bad blocks are skipped to 3266speed up the badblocks test. There is also a persistent rescan 3267feature which causes badblocks to run until it has completed some 3268number of passes without discovering any new bad blocks. 3269 3270Badblocks now checks to see if the device is mounted and refuses to do 3271the tests involving writing to the device if it is mounted. Also, 3272badblocks now allows the number of blocks to be checked to be 3273defaulted to the size of the partition. 3274 3275Fixed a bug in fsck which didn't allow non-root users to be able to 3276check filesystems if there were any LABEL= or UUID= entries in 3277/etc/fstab. 3278 3279The Hurd doesn't support the filetype filesystem feature. The mke2fs 3280program now makes sure that for the Hurd, the filestype feature is 3281turned off. E2fsck will check to see if the filetype feature is 3282turned on for Hurd filesystems, and offer to turn off the feature. 3283 3284Mke2fs now has a safety check to make sure the number of blocks do not 3285exceed 32 bits even on a 64 bit platform. 3286 3287Really fixed a bug in fsck to allow "fsck -As" to run interactive 3288fsck's. (For those people who like to do interactive fsck's in the 3289/etc/rc scripts!?!) 3290 3291Debugfs has a few new features: the rdump command, which will do a 3292recursive dump of a directory and all of its contents, and the lcd 3293command which does a local chdir (much like the ftp command of the 3294same name). In addition, the debugfs program and the open_filesystem 3295command now takes three new options: -b and -s, which allows the 3296blocksize and superblock location to be specified, and the -c option 3297which is used in catastrophic situations where the block group 3298descriptors are corrupt. If the -c option is specified, debugfs will 3299skip trying to read in the block and inode bitmaps. 3300 3301Debufs's lsdel command was fixed to handle bad blocks in the inode 3302table. 3303 3304A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use 33054 digit years. 3306 3307General improvements in error messages 3308 3309 - Mke2fs prints a sane error message if the partition size is zero 3310 (usually because the partition table wasn't reread by the 3311 kernel due to the partition being busy), instead of "invalid 3312 argument passed to ext2 library while initializing superblock". 3313 3314 - Fsck now prints more self-explanatory message if an invalid UUID= 3315 or LABEL= specification is passed to it. 3316 3317UUID library changed to use the LGPL. 3318 3319Fixed a bug in the UUID library where very rapid calls to the 3320time-based UUID generator could cause duplicate UUID's to be returned. 3321This was not a problem for e2fsprogs, but it could be a problem for 3322other users of the library. 3323 3324Make the UUID library more robust in the face of missing or an 3325improper /dev/urandom or /dev/random files. 3326 3327Added some random portability fixes for Solaris. 3328 3329Some minor man page updates. 3330 3331Fixed a memory leak in the ss library. 3332 3333 3334Programmer's notes: 3335------------------- 3336 3337We now try to use lseek64 and open64 from the LFS if possible. 3338 3339The 3rd parameter in e2p's print_flags is now a flags word, instead of 3340a boolean option. 3341 3342The mark and unmark bitmap functions now return the previous state of 3343the bit that was being changed, which is useful for some speed 3344optimizations. 3345 3346The following functions have been added to enhance the badblocks list 3347handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and 3348ext2fs_badblocks_equal. 3349 3350The ext2 header files now have the latest journalling fields to the 3351superblock. 3352 3353The ext2fs_mkdir function in libext2fs now properly backs out of error 3354conditions robustly. 3355 3356Cleaned up makefiles: 3357 - to cleanly compile with the -j flag. 3358 - so distclean removes all generated files. 3359 - so in case of an error while installing header files, the make aborts. 3360 3361Fix test_script so that it works correctly when compiling in the 3362source directory. 3363 3364The random UUID generation routine has been made slightly better in 3365the case where /dev/random doesn't exist. (Use of randomly-based UUID 3366is still not recommended if /dev/random doesn't exist, however; it's 3367better to use the time/ethernet MAC address UUID in this case.) 3368 3369Clean up the build process so it's more friendly in case of missing 3370directories. 3371 3372The ext2fs header file can now be #include'd into C++ programs. 3373 3374The e2p.h header file is now installed. 3375 3376Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds. 3377 3378 3379 3380E2fsprogs 1.18 (November 10, 1999) 3381================================== 3382 3383Fix a core dumping bug in e2fsck if an imagic inode is present or 3384(more rarely) if the filesystem is badly corrupted enough that e2fsck 3385has to restart pass 1 processing. E2fsck now closes the filesystem 3386before freeing a large number of its data structures, so in the case 3387of future memory faults, at least the fixed filesystem will be fully 3388written out. 3389 3390If a filesystem doesn't support imagic inodes, and e2fsck discovers an 3391imagic inode, it will offer to clear the imagic flag. 3392 3393E2fsck will now offer to clear the immutable flag on special files 3394(device/socket/fifos) when running it in non-preen mode. 3395 3396E2fsck will now set the filetype when creating /lost+found, and when 3397connected orphaned inodes to /lost+found. 3398 3399Debugfs's ncheck and icheck commands now handles the case where there 3400are bad blocks in the inode table without bombing out. 3401 3402The badblocks list processing code has been made more efficiently for 3403appending a large number of (ordered) badblocks to the badblocks list. 3404 3405Some minor man page updates. 3406 3407Fsck now allows interactive e2fsck's when using fsck -As (not a common 3408mode, but some people like to do this in boot scripts for silly reasons). 3409 3410Programmer's notes: 3411------------------- 3412 3413The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet 3414with the problem code convention. 3415 3416The badblocks list regression test program has been updated to work 3417with previously made API name changes. 3418 3419The ext2fs_free() command now uses the new badblocks API to avoid 3420using the compatibility layer. 3421 3422Added new regression test cases; the run_e2fsck test script now 3423supports the ability for a test case to run a prepratory command 3424before running e2fsck. 3425 3426E2fsprogs 1.17 (October 26, 1999) 3427================================= 3428 3429Fixed nasty typo in fsck which caused parallelized fsck's to go into an 3430infinite loop. 3431 3432Fixed a bug in fsck where it used strncmp to compare a binary UUID, 3433thus potentially causing problems if a binary UUID contained a NULL 3434character. 3435 3436E2fsck now uses stricter checks for directory entries in pass 2: 3437zero-length filenames are not allowed; neither are 8 byte long 3438directory entries. 3439 3440The debugfs "dirty" command now clears the filesystem valid bit. 3441(Previously this just set the dirty-as-in-needs-writing-out-to-disk 3442bit in the in-core superblock image. The new functionality is more 3443what the user expects, and is more useful.) 3444 3445Added a debugging hook to test parallel fsck; if the environment 3446variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive 3447will be checked in parallel when they normally would not be. 3448 3449Programmer's notes: 3450------------------- 3451 3452Fixed some #ifdef's for compilation under the Hurd OS. 3453 3454Fixed minor W2K compatibility problems. 3455 3456Fixed some miscellaneous GCC warnings. 3457 3458 3459E2fsprogs 1.16 (October 22, 1999) 3460================================= 3461 3462Fixed a race condition bug in fsck; when printing a progress bar, if 3463checking multiple filesystems in parallel, it was possible for fsck to 3464send e2fsck a SIGUSR1 signal before e2fsck had installed its signal 3465handler, which would cause it to terminate with a signal 10. 3466 3467E2fsck now properly handles filesystems that have the 3468INCOMPAT_FILETYPE feature turned on. It can be used to convert a 3469filesystem into using or not using FILETYPE feature. 3470 3471E2fsck now properly handles filesystems that have the IMAGIC feature 3472turned on (this is used on Linux AFS servers). 3473 3474The mke2fs program now creates filesystems that have the filetype and 3475sparse_superblock features enabled by default, unless it is run on a 3476pre-2.2 kernel. These features are not supported by a pre-2.2 kernel, 3477so there is now a new flag -O which allows the user to specify with 3478which features she would like to create the filesystem; "mke2fs -O 3479none" will create a filesystsem compatible with 2.0 kernels. 3480 3481The tune2fs program now has a -O option which allows the user to set 3482and reset "safe" filesystem features. Currently, the only ones which 3483allows to be modified are the filetype and sparse_superblock features. 3484Note setting or clearing either feature will require running e2fsck on 3485the filesystem afterwards. (n.b. Clearing the sparse_superblock feature 3486requires that there is enough free space on the filesystem for the 3487extra superblocks which will be created by e2fsck.) 3488 3489Debugfs can now set and print filesystem features in the superblock 3490using the "features" command. Dumpe2fs will print out the complete 3491set of features when listing the superblock. 3492 3493Dumpe2fs has new options -f (force) and -h (header-only). 3494 3495Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead 3496message to come up. This could happen when decrementing or 3497incrementing a link count could result in an overflow. 3498 3499Fixed a bug in e2fsck where the block count on the lost+found 3500directory would not be properly incremented when the directory was 3501expanded to the point where an indirect block needed to be allocated. 3502 3503E2fsck now makes some additional sanity checks on the superblock to 3504avoid crashing or giving a memory allocation error if some of the 3505values in the superblock are unresonable (but the superblock otherwise 3506looks valid). 3507 3508Fixed a bug in e2fsck where a very badly corrupted filesystem might 3509require two passes to completely fix the filesystem. This happened if 3510an inode claimed blocks that was part of the filesystem metadata 3511(typically, when garbage was written into an inode table or indirect 3512block, since this kind of filesystem corruption normally doesn't 3513happen otherwise). 3514 3515On the Alpha, glibc declares st_flags although it isn't actually used; 3516the configure script was improved to detect this case so that 3517e2fsprogs can avoid using the non-functional stat field. 3518 3519The manual pages were updated to use a more consistent formatting 3520style consistent with standard Unix man pages. Mke2fs's man page 3521added documentation for a few previously undocumented options. 3522 3523Fixed minor display bugs in tune2fs and mke2fs. 3524 3525Programmer's notes: 3526------------------- 3527 3528Improved portability of e2fsprogs to non-Unix systems (in particular, NT). 3529 3530Added features to parse and print feature strings into the e2p library. 3531(e2p_feature2string, e2p_string2feature, e2p_edit_feature). 3532 3533ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories 3534whose directory entries contain proper filetype information if the 3535filesystem supports it. 3536 3537ext2fs_link() now uses the low 3 bits of its flags parameter to pass 3538the directory entry filetype information. This is used to set the 3539directory entry filetype information if the filesystem supports it. 3540 3541Fixed a bug in ext2fs_expand_dir() where the block count in a 3542directory's inode would not be properly incremented when the directory 3543was expanded to the point where an indirect block needed to be 3544allocated. 3545 3546 3547E2fsprogs 1.15 (July 18, 1999) 3548============================== 3549 3550Add configuration checks so that e2fsprogs will compile cleanly on 3551Linux 2.3 kernels that have renamed i_version to i_generation. 3552 3553E2fsck now prints a progress/completion bar (and not just a simple 3554spinner) if the -C0 option is requested or if it receives a SIGUSR1 3555signal. Fsck will automatically manage the (potentially muliple) 3556e2fsck processes to print completion bars if it is given a -C option, 3557with the right thing happening if multiple filesystems are being 3558checked in parallel. 3559 3560Mke2fs now has better automatic hueristics to determine the filesystem 3561parameters to be used for a particular filesystem. Added a new option 3562-T which allows the user to specify how the filesystem is to be used, 3563which helps mke2fs do a better job selecting the filesystem parameters. 3564 3565Mke2fs now creates revision 1 filesystems by default, and with the 3566sparse superblock feature enabled. The sparse superblock feature is 3567not understood by Linux 2.0 kernels, so they will only allow read-only 3568mounts of filesystems with this sparse superblocks. 3569 3570Fix bug where if /dev/null couldn't be opened (should never happen), 3571e2fsck would hang in a tight loop. 3572 3573Make e2fsck handle the case where /lost+found isn't a directory. 3574 3575E2fsck now uses mallinfo if it exists to get accurate statistics about 3576its memory usage. 3577 3578Fix bug in e2fsck where it wouldn't check to see if a disconnected 3579inode had any problems before connecting it to /lost+found. 3580 3581Add check to e2fsck so it makes sure that total number of inodes in 3582the filesystem is a sane number. 3583 3584Fix fencepost error when clearing an the end of the block bitmap which 3585caused the last block in the bitmap not to get cleared. 3586 3587Cleaned up a number of messages in e2fsck: 3588 * The message "Group's #'s copy of the group descriptor..." 3589 was fixed so that the correct number would be displayed. 3590 * Added missing space in the "disk write-protected" error messsage 3591 * Cleaned up the error message printed when a non-interactive 3592 e2fsck needs to abort a check because the filesystem 3593 appears to be mounted. 3594 3595Added a new command-line utility, uuidgen, which will create and print 3596a UUID. 3597 3598Make debugfs's icheck command more robust by checking to make sure an 3599inode has valid blocks before interarting over the inode's blocks. 3600 3601UUID generation now uses a random-based scheme whenever possible to 3602prevent potential privacy problems. 3603 3604Man pages for all of the UUID functions in the lirbary were added. 3605 3606Fixed bug in fsck so it won't coredump if a filesystem not in 3607/etc/fstab is given to it. 3608 3609Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab 3610that most of the other mount utilities understands. 3611 3612Mke2fs will make a filesystem even if it appears mounted if the force 3613option is given. 3614 3615Dumpe2fs has new command-line options which allow a filesystem expert 3616to specify the superblock and blocksize when opening a filesystem. 3617This is mainly useful when examining the remains of a toasted 3618filesystem. 3619 3620The badblocks program has been updated to display correctly on disks 3621with large block numbers. 3622 3623The badblocks program no longer gives spurious errors when errors 3624occur on non-block boundaries, which is common if the blocksize is 3625larger than 1k. 3626 3627Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the 3628MKE2FS_SYNC environment variable is set. This is to work around a VM 3629bug in the 2.0 kernel. I've heard a report that a RAID user was able 3630to trigger it even using a 2.2 kernel, but hopefully it will not be 3631needed for most Linux 2.2 users. 3632 3633Fixed miscellaneous documentation and man pages. 3634 3635Programmer's notes: 3636------------------- 3637 3638Cleaned up functions such as pass1_get_blocks, pass1_read_inode which 3639in e2fsck's pass1.c really should have been static. 3640 3641The return value of the uuid_compare() function was changed to make it 3642match with the convetions used by strcmp, memcmp, and Paul Leach's 3643UUID sample document. 3644 3645The "make depend" process has now been made more automated; it now 3646automatically word-wraps the dependencies, and only replaces source 3647Makefile.in if there has been a change in the dependencies. Also, a 3648top-level "make depend" now recurses through all the subdirectories 3649automatically. 3650 3651The Makefile in .../util has been changed so that subst is built using 3652the native C compiler during a cross-compilation, since the subst 3653program is only used during the build process. Also add an explicit 3654rule to build util/subst by cd'ing to the correct directory and 3655running Makefile. 3656 3657The man directories are defined in terms mandir, so that the configure 3658script can override the location of the manual pages. 3659 3660The config files have been updated to recognize new machine types for 3661both the i386 and alpha families. 3662 3663Fsck has been modified so that it will accurately create an 3664fsck_instance even when the noexecute flag is set. This allows for 3665accurate debugging of the fsck pass structure. Also, when the verbose 3666flag is given twice, fsck will print debugging information about when 3667fsck is waiting for jobs to finish. 3668 3669 3670E2fsprogs 1.14 (January 9, 1999) 3671================================ 3672 3673Fix the fstab parsing code so that it can handle blank lines and 3674comment characters. Also, missing pass numbers need to be treated as 3675zero. 3676 3677Fixed a bug in e2fsck where under some circumstances (when e2fsck 3678needs to restart processing after fixing an egregious inconsistency) 3679it would try to access already freed memory. 3680 3681E2fsck now prints non-printable characters in directory entries and 3682pathnames using '^' and 'M-' notation. 3683 3684Fixed chattr so that it will ignore symbolic links when doing 3685recursive descent traversals. For both chattr and lsattr, no longer 3686print the version string unless the -V option is given. 3687 3688Allow the system administrator to directly specify the number of 3689inodes desired in the filesystem, for some special cases where this is 3690necessary. 3691 3692Fix portability problems so that e2fsprogs can be compiled under Linux 36931.2 systems and Solaris systems. 3694 3695Update the config.guess file with a more recent version that will 3696identify newer Linux platforms. 3697 3698Programmer's notes 3699------------------ 3700 3701Ext2fs_read_inode and ext2fs_write_inode will now return an error if 3702an inode number of zero is passed to them. 3703 3704E2fsprogs 1.13 (December 15, 1998) 3705================================== 3706 3707Fixed a bug in debugfs where an error messages weren't getting printed 3708when the ext2 library routines to read inodes returned errors in the 3709stat, cmri and rm commands. 3710 3711Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is 3712provided, it won't create an inode table smaller than the minimum 3713number of inodes required for a proper ext2 filesystem. 3714 3715Fsck now parses the /etc/fstab file directly (instead of using 3716getmntent()), so that it can distinguish between a missing pass number 3717field and pass number field of zero. This caused problems for 3718diskless workstations where all of the filesystems in /etc/fstab have 3719an explicit pass number of zero, and fsck could not distinguish this 3720from a /etc/fstab file with missing pass numbers. 3721 3722E2fsck will create a /lost+found directory if there isn't one in the 3723filesystem, since it's safer to create the lost+found directory before 3724it's needed. 3725 3726Fixed e2fsck so that it would detect bogus immutable inodes which 3727happen to be sockets and FIFO files, and offer to clear them. 3728 3729If a filesystem has multiple reasons why it needs to be checked, and 3730one of the reasons is that it is uncleanly mounted, e2fsck will print 3731that as the reason why the filesystem is being checked. 3732 3733Cleaned up the output routines of mke2fs so that it doesn't overflow 3734an 80 column display when formating really big filesystems. 3735 3736Added a sanity check to e2fsck to make sure that file descriptors 0, 37371, 2 are open before opening the hard disk. This avoids a problem 3738where a broken program might exec e2fsck with those file descriptors 3739closed, which would cause disastrous results if the kernel returns a 3740file descriptor for the block device which is also used by FILE * 3741stdout. 3742 3743Fixed up the e2fsck progress reporting functions so that the values 3744reliably reach 100% at the completion of all of the e2fsck passes. 3745 3746Fixed minor documentation bugs in man pages and usage messages. 3747 3748Programmer's notes: 3749------------------- 3750 3751Fixed a number of lint warnings in the ext2fs library and potential 3752portability problems from other OS's header files that might define 3753CPP macros for names like "max" and "min". 3754 3755ext2fs_badblocks_list_add() has been made more efficient when it needs 3756to grow the bad blocks list. 3757 3758Fixed a bug in e2fsck which caused it to dereference a freed pointer 3759just before exiting. 3760 3761Fixed the substition process for generating the mk_cmds and compile_et 3762scripts so that they will work outside of the build tree. 3763 3764Add sanity check to e2fsck so that if an internal routine 3765(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer 3766and causing a core dump. This should never happen, but... 3767 3768E2fsprogs 1.12 (July 9, 1998) 3769================================== 3770 3771E2fsprogs now works with glibc (at least with the version shipped wtih 3772RedHat 5.0). The ext2fs_llseek() function should now work even with 3773i386 ELF shared libraries and if llseek() is not present. We also 3774explicitly do a configure test to see if (a) llseek is in libc, and 3775(b) if llseek is declared in the system header files. (See standard 3776complaints about libc developers don't understand the concept of 3777compatibility with previous versions of libc.) 3778 3779The ext2fs library now writes out the block group number in each of 3780the superblock copies. This makes it easier to automatically 3781determine the starting block group of the filesystem when the block 3782group information is trashed. 3783 3784Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature, 3785which means that e2fsprogs will ignore the high 8 bits of the 3786directory entry's name_len field, so that it can be used for other 3787purposes. 3788 3789Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature. 3790E2fsprogs will now support filesystems with 64-bit sized files. 3791 3792Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature. 3793 3794Added new program "e2label", contributed by Andries Brouwer. E2label 3795provides an easy-to-use interface to modify the filesystem label. 3796 3797Fixed bug so that lsattr -v works instead of producing a core dump. 3798 3799Fixed a minor bug in mke2fs so that all groups with bad superblock 3800backup blocks are printed (not just the first one). 3801 3802Mke2fs will check the size of the device, and if the user specifies a 3803filesystem size larger than the apparent size of the device it will 3804print a warning message and ask if the user wants to proceed. 3805 3806E2fsck has a new option -C, which sends completion information to the 3807specified file descriptor. For the most part, this is intended for 3808programs to use, although -C 0 will print a spinning character to the 3809stdout device, which may be useful for users who want to see something 3810happening while e2fsck goes about its business. 3811 3812Fixed a bug in e2fsck which could cause a core dump when it needs to 3813expand the /lost+found directory, and sometimes the bitmaps haven't 3814been merged in. Also fixed a related bug where ext2fs_write_dir_block 3815was used to write out a non-directory block. (Which would be bad on a 3816non-Intel platform with byte swapping going on.) 3817 3818Fixed bug in e2fsck where it would print a "programming error" message 3819instead of correctly identifying where a bad block was in used when 3820the bad block was in a non-primary superblock or block group 3821descriptor. Also fixed a related bug when sparse superblocks are in 3822use and there is a bad block where a superblock or block group 3823descriptor would have been in a group that doesn't include a 3824superblock. 3825 3826Fixed a bug in e2fsck (really in libext2fs's dblist function) where if 3827the block group descriptor table is corrupt, it was possible to try to 3828allocate a huge array, fail, and then abort e2fsck. 3829ext2fs_get_num_dirs() now sanity checks the block group descriptor, 3830and subsitutes reasonable values if the descriptors are obviously bogus. 3831 3832If e2fsck finds a device file which has the immutable flag set and the 3833i_blocks beyond the normal device number are non-zero, e2fsck will 3834offer to remove it, since it's probably caused by garbage in the inode 3835table. 3836 3837When opening a filesystem, e2fsck specially checks for the EROFS error 3838code, and prints a specific error message to the user which is more 3839user friendly. 3840 3841If the filesystem revision is too high, change the e2fsck to print 3842that this is either because e2fsck is out of date, or because the 3843superblock is corrupt. 3844 3845E2fsck now checks for directories that have duplicate '.' and '..' 3846entries, and fixes this corruption. 3847 3848E2fsck no longer forces a sync of the filesystem (with attendant sleep 3849calls) at all times. The ext2fs_flush() function now performs a sync 3850only if it needed to write data blocks to disk. 3851 3852Fixed a minor bug in e2fsck's pass1b's file cloning function, where 3853certain errors would not be properly reported. 3854 3855Updated and expanded a few points in the man pages which users 3856complained wheren't explicit enough. 3857 3858Added special case byte-swapping code if compiling on the PowerPC, to 3859accomodate the strange big-endian variant of the ext2 filesystem that 3860was previously used on the PowerPC port. 3861 3862 3863Programmer's notes: 3864------------------- 3865 3866Removed C++ keywords from the ext2fs libraries so that it could be 3867compiled with C++. 3868 3869E2fsck's internal organization has now been massively reorganized so 3870that pass*.c don't have any printf statements. Instead, all problems 3871are reported through the fix_problem() abstraction interface. E2fsck 3872has also been revamped so that it can be called as a library from a 3873application. 3874 3875Added new fileio primitives in libext2fs for reading and writing 3876files on an unmounted ext2 filesystem. This interface is now used by 3877debugfs. 3878 3879Added a new libext2fs function for mapping logical block numbers of 3880a file to a physical block number. 3881 3882Added a new libext2fs function, ext2fs_alloc_block(), which allocates 3883a block, zeros it, and updates the filesystem accounting records 3884appropriately. 3885 3886Added a new libext2fs function, ext2fs_set_bitmap_padding(), which 3887sets the padding of the bitmap to be all one's. Used by e2fsck pass 5. 3888 3889The libext2fs functions now use a set of memory allocation wrapper 3890functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem, 3891instead of malloc, free, and resize. This makes it easier for us to 3892be ported to strange environments where malloc, et. al. aren't 3893necessarily available. 3894 3895Change the libext2fs fucntion to return ext2-specific error codes 3896(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using 3897and depending on the existence of system error codes (such as EEXIST 3898and ENOENT). 3899 3900Renamed io.h to ext2_io.h to avoid collision with other OS's header 3901files. 3902 3903Add protection against ext2_io.h and ext2fs.h being included multiple 3904times. 3905 3906The types used for memory lengths, etc. have been made more portable. 3907In generla, the code has been made 16-bit safe. Added Mark 3908Habersack's contributed DOS disk i/o routines. 3909 3910Miscellaneous portability fixes, including not depending on char's 3911being signed. 3912 3913The io_channel structure has a new element, app_data, which is 3914initialized by the ext2fs routines to contain a copy of the filesystem 3915handle. 3916 3917ext2fs_check_directory()'s callback function may now return the error 3918EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to 3919really do the checking, despite the presence of the callback function. 3920 3921 3922E2fsprosg 1.11 (June 17, 1997) 3923============================== 3924 3925Fixed e2fsck to detect (previously ignored) conflicts between the 3926superblock or block group descriptors and block bitmaps, inode 3927bitmaps, and inode tables. 3928 3929Fixed bug in e2fsck so that when the message printed out when a block 3930or inode bitmap conflicts with other data, it has the correct group 3931number. 3932 3933Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed 3934to badblocks. This meant that not all of the filesystem was being 3935tested for bad blocks! 3936 3937Fixed an array boundary overrun case which cropped up in 3938ext2fs_badblocks_list_test when a user tried running "mke2fs -c 3939-b 4096". 3940 3941Adjusted the number of columns printed by mke2fs when displaying the 3942superblock backups to avoid running over 80 columns when making a 3943really big filesystem. 3944 3945Fixed up the man pages for e2fsck, debugfs, badblocks, chattr, 3946dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar 3947fixes), thanks to some suggestions from Bill Hawes (whawes@star.net). 3948 3949Programmer's notes: 3950------------------- 3951 3952Fixed install rule in lib/ss so that ss_err.h is actually getting 3953installed. 3954 3955Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting 3956bassed back to the caller. 3957 3958Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been 3959setting the current inode number (which meant this function wasn't 3960working at all). 3961 3962Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all 3963blocks in the bitmap when increasing the size of the bitmap. 3964 3965Changed the initial number of blocks allocated by ext2fs_init_dblist() 3966to be more realistic. 3967 3968Added a new function ext2fs_allocate_group_table, which sets up the 3969group descriptor information (and allocates inode and block bitmaps, 3970and inode tables for a particular group). The function was created by 3971factoring out code form ext2fs_allocate_tables(). 3972 3973Added a new function ext2fs_move_blocks which takes a bitmap of the 3974blocks to be moved, and moves them to another location on the 3975boardboard. 3976 3977Make the unix_io channel's io_channel_flush implementation calls sync() 3978to to flush the kernel buffers to disk. 3979 3980Added a new function ext2fs_dblist_count returns the number of 3981directory blocks in dblist. 3982 3983 3984E2fsprogs 1.10 (April 24, 1997) 3985=============================== 3986 3987Mke2fs once again defaults to creating revision #0 filesystems, since 3988people were complaining about breaking compatibility with 1.2 kernels. 3989Warning messages were added to the mke2fs and tune2fs man pages that 3990the sparse superblock option isn't supported by most kernels yet (1.2 3991and 2.0 both don't support parse superblocks.) 3992 3993Added new flag to mke2fs, -R <raid options>, which allows the user to 3994tell mke2fs about the RAID configuration of the filesystem. Currently 3995the only supported raid option is "stride" which specifies the width 3996of the RAID stripe. 3997 3998Fixed bug in e2fsck where pass1b would bomb out if there were any 3999blocks marked bad in the inode table. 4000 4001Fixed rare bug in mke2fs where if the user had a very unlucky number 4002of blocks in a filesystem (probability less than .002) the resulting 4003filesystem would be corrupt in the last block group. 4004 4005Fixed bug where if e2fsck tried to allocate a block to fix a 4006filesystem corruption problem and the filesystem had no free blocks, 4007ext2fs_new_block() would loop forever. 4008 4009The configure script now checks explicitly to see if "-static" works, 4010since that can't be assumed to be true --- RedHat doesn't install 4011libc-static by default. 4012 4013Fixed bug in libext2's block iterator functions where under some 4014cirmcustances, file with holes would cause the bcount parameter to the 4015callback function to be incorrect. This bug didn't affect any of 4016e2fsprogs programs, but it was discovered by Paul Mackerras, the 4017author of the PPC boot loader. 4018 4019Removed use of static variables to store the inode cache in libext2fs. 4020This caused problems if more than one filesystem was accessed via 4021libext2fs (static variables in libraries are generally a bad idea). 4022Again, this didn't affect e2fsprogs programs, but it was discovered by 4023Paul Mackerras. 4024 4025Fixed minor bugs and version code drift to assure that e2fsprogs 1.10 4026will compile cleanly with 1.2.13 kernels (even with a.out shared 4027libraries!) 4028 4029Programmer's notes: 4030------------------- 4031 4032Added new functions to duplicate an ext2 filesystem handle, and its 4033associated substructure. New functions: ext2fs_dup_handle(), 4034ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap(). 4035Other structures, such as the io_channel and the inode_cache, now have 4036a ref count so that they only get freed when they are no longer used 4037by any filesystem handle. (These functions were added as part of the 4038development effort for an ext2 resizer). 4039 4040E2fsprogs 1.09 (April 14, 1997) 4041=============================== 4042 4043Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was 4044accidentally introduced in the 1.08 release. The overhead calculation 4045was accidentally removed, which caused ext2fs_initialize() to not 4046notice when the filesystem size needed to be adjusted down because 4047there wasn't enough space in the last block group. 4048 4049Fixed bug in version parsing library routine; it was always parsing 4050the library version string, instead of using the passed-in string. 4051 4052Clarified chattr man page. 4053 4054E2fsprogs 1.08 (April 10, 1997) 4055=============================== 4056 4057E2fsck 1.07 was very slow when checking very large filesystems with a 4058lot of files that had hard links (i.e., news spools). This was fixed 4059by seriously revamping the icount abstraction. Added a formal test 4060suite for the icount abstraction. 4061 4062Debugfs now has a "-l" option to the "ls" command, which lists the 4063inode number, permissions, owner, group, size, and name of the files 4064in the directory. 4065 4066Fix a bug in e2fsck where when a directory had its blocks moved to 4067another location during the pass 1b processing, the directory block 4068list wasn't updated, so pass 2 wouldn't check (and correct) the 4069correct directory block. 4070 4071E2fsck will now treat inodes which contain blocks which are claimed by 4072the filesystem metadata by treating them as multiply claimed blocks. 4073This way, the data in those blocks can be copied to a new block during 4074the pass 1b--1d processing. 4075 4076E2fsck will attempt to determine the correct superblock number and 4077display it in the diagnostic and warning messages if possible. 4078 4079Add support for a new (incompatible) feature, "sparse_super". This 4080feature reduces the number of blocks which contain copies of backup 4081superblocks and block group descriptors. (It is only an incompatible 4082feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now 4083support a new -s option; e2fsck will recognize filesystems built with 4084this feature turned on. 4085 4086E2fsck now checks the library to make sure is the correct version, 4087using new library functions. (This helps to diagnose incorrectly 4088installed e2fsprogs distributions.) 4089 4090Dumpe2fs now prints more information; its now prints the the 4091filesystem revision number, the filesystem sparse_super feature (if 4092present), the block ranges for each block group, and the offset from 4093the beginning of the block group. 4094 4095Mke2fs now distributes the inode and block bitmap blok so that the 4096won't be concentrated in one or two disks in RAID/striping setups. 4097Also, if the user chooses a 2k or 4k block group, mke2fs will try to 4098choose the largest blocks per group that be chosen. (For 2k blocks, 4099you can have up to 16384 blocks/group; for 4k blocks, you can have up 4100to 32768 blocks/group.) Previously mke2fs would not allow 4101specification of more than 8192 blocks per group, even if you were 4102using a 2k or 4k block group. 4103 4104Programmer's notes: 4105------------------- 4106 4107Added a new function ext2fs_create_icount2() which takes a "hint" 4108argument. This hint argument presets the icount array with the list 4109of inodes which actually need to be in the icount array. This really 4110helps to speed up e2fsck. 4111 4112Added a new function ext2fs_icount_validate() which checks the rep 4113invariant for the icount structure. This is used mostly for testing. 4114 4115The error mesasage given when a bad inode number is passed to 4116test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of 4117EXT2FS_UNMARK_ERROR). 4118 4119Added a new function ext2fs_set_dir_block which sets the block of a 4120dblist entry, given the directory inode and blockcnt. 4121 4122Added a new function ext2fs_get_library_version() which returns the 4123current library version, and ext2fs_parse_version_string() which 4124returns a version number based on a e2fsprogs version string. 4125 4126The icount functions will return EINVAL if the passed in inode number 4127is out of bounds. 4128 4129E2fsprogs 1.07 (March 9, 1997) 4130============================== 4131 4132E2fsck is now uses much less memory when checking really large 4133filesystems (or rather, filesystems with a large number of inodes). 4134Previously a filesystem with 1 million inodes required 4 megabytes of 4135memory to store inode count statistics; that storage requirement has 4136now been reduced to roughly half a megabyte. 4137 4138E2fsck can now properly deal with bad blocks appearing inside the 4139inode table. Instead of trying to relocate the inode table (which 4140often failed because there wasn't enough space), the inodes in the bad 4141block are marked as in use. 4142 4143E2fsck will automatically try to use the backup superblocks if the 4144primary superblocks have a bad magic number or have missing meta-data 4145blocks (or meta-data blocks which are out of range). 4146 4147E2fsck's pass 3 has been made more efficient; most noticeable on 4148filesystems with a very large number of directories. 4149 4150Completely revamped e2fsck's system of printing problem reports. It 4151is now table driven, to make them more easily customizeable and 4152extendable. Error messages which can be printed out during preen mode 4153are now one line long. 4154 4155Fixed e2fsck's filesystem swapping code so that it won't try to swap 4156fast symbolic links or deleted files. 4157 4158Fixed e2fsck core dumping when fixing a filesystem which has no 4159directories (not even a root directory). 4160 4161Added a check to e2fsck to make sure that the length of every 4162directory entry is a multiple of 4 (since the kernel complains if it 4163isn't). 4164 4165Added a check to e2fsck to make sure that a directory entry isn't a 4166link to the root directory, since that isn't allowed. 4167 4168Added a check to e2fsk to now make sure the '.' and '..' directory 4169entries are null terminated, since the 2.0 kernel requires it. 4170 4171Added check to write_bitmaps() to make sure the superblock doesn't get 4172trashed if the inode or block bitmap is marked as being block zero. 4173 4174Added checking of the new feature set fields in the superblock, to 4175avoid dealing with new filesystem features that this package wasn't 4176set up to handle. 4177 4178Fixed a fencepost error in ext2fs_new_block() which would occasionally 4179try to allocate a block beyond the end of a filesystem. 4180 4181When the UUID library picks a random IEEE 802 address (because it 4182can't find one from a network card), it sets the multicast bit, to 4183avoid conflicting with a legitimate IEEE 802 address. 4184 4185Mke2fs now sets the root directory's owner to be the real uid of the 4186user running mke2fs. If the real uid is non-zero, it also sets 4187the group ownership of the root directory to be the real group-id of 4188the user running mke2fs. 4189 4190Mke2fs now has more intelligent error checking when it is given a 4191non-existent device. 4192 4193When badblocks is given the -vv option, it now updates the block that 4194it is currently testing on every block. 4195 4196Fixed a bug in fsck where it wouldn't modify the PATH envirnoment 4197currently correctly if PATH wasn't already set. 4198 4199Shared libraries now built with dependencies. This allows the shared 4200library files to be used with dlopen(); it also makes the transition 4201to libc 6 easier, since ld.so can tell which libc a particular shared 4202library expects to use. 4203 4204Programmer's notes: 4205------------------- 4206 4207Added new abstraction (defined in dblist.c) for maintaining a list of 4208blocks which belongs to directories. This is used in e2fsck and other 4209programs which need to iterate over all directories. 4210 4211Added new functions which test to see if a contiguous range of blocks 4212(or inodes) are available. (ext2fs_*_bitmap_range). 4213 4214Added new function (ext2_inode_has_valid_blocks) which returns true if 4215an inode has valid blocks. (moved from e2fsck code). 4216 4217Added new function (ext2fs_allocate_tables) which allocates the 4218meta-data blocks as part of initializing a filesystem. (moved from 4219mke2fs code). 4220 4221Added a new I/O manager for testing purposes. It will either allow a 4222program to intercept I/O requests, or print debugging messages to 4223trace the activity of a program using the I/O manager. 4224 4225The badblocks_list functions now store the bad blocks in a sorted 4226order, and use a binary search to speed up badblocks_list_test. 4227 4228The inode scan function ext2fs_get_next_inode() may now return a soft 4229error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in 4230those cases where part of an inode table is missing or there is a bad 4231block in the inode table. 4232 4233Added a new function (ext2fs_block_iterate2) which adds new arguments to 4234the callback function to return a pointer (block and offset) to the 4235reference of the block. 4236 4237Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an 4238application to jump to a particular block group while doing an inode 4239scan. 4240 4241The badblocks list functions were renamed from badblocks_* to 4242ext2fs_badblocks_*. Backwards compatibility functions are available 4243for now, but programs should be modified to use the new interface. 4244 4245Some of the library functions were reorganized into separate files to 4246reduce the size of some programs which statically link against the 4247ext2 library. 4248 4249Put in some miscellaneous fixes for the Alpha platform. 4250 4251 4252E2fsprogs 1.06 (October 7, 1996) 4253================================ 4254 4255Fixed serious bug in e2fsck: if the block descriptors are bad, don't 4256smash the backup copies in ext2fs_close(). (The problem was that when 4257e2fsck -p discovered the problem, while it was closing the filesystem 4258and exiting, it was also blowing away the backup superblocks on the 4259disk, which was less than friendly.) We now make it the case that we 4260only write out the backup superblock and the back block descriptors if 4261the filesystem is completely free from problems. 4262 4263Fixed a bug in block_interate in the lib/ext2fs library which caused 4264e2fsck to fail on GNU Hurd-created filesystems. 4265 4266Add support for Linux/FT's bootloader, which actually uses 4267EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want 4268to clear the inode. 4269 4270Add support for the "A" (no atime update) attribute. (Note: this 4271attribute is not yet in production kernels.) 4272 4273The test suite is not automatically run when doing a "make all" from 4274the top level directory. Users should manually run "make check" if 4275they wish to run the test suite. 4276 4277Upon a preenhalt(), make the printed message more explicit that 4278running e2fsck "MANAULLY" means without the -p or -a options. 4279 4280In e2fsck, if a disconnected inode is zero-length, offer to clear it 4281instead of offering to connect it to lost+found. 4282 4283In e2fsck, if a filesystem was just unmounted uncleanly, and needs 4284e2fsck to be run over it, change e2fsck to explicitly display this 4285fact. 4286 4287For dumpe2fs and e2fsck, cause the -V option to print out which 4288version of the ext2fs library is actually getting used. (This will 4289help detect mismatches of using a 1.06 utility with a 1.05 library, 4290etc.) 4291 4292Programmers' notes: 4293------------------- 4294 4295EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits 4296the naming convention. 4297 4298In ext2fs_initialize(), make sure the description for the inode bitmap 4299is correctly initialize. 4300 4301Fixed minor type typo in ext2fs_allocate_generic_bitmap(); 4302 4303E2fsprogs 1.05 (September 7, 1996) 4304================================== 4305 4306Add support for new fields in the ext2 superblock --- volume name, 4307volume UUID, and last mounted field. Dumpe2fs displays these fields, 4308tune2fs and mke2fs allows you to set them. E2fsck will automatically 4309generate a UUID for those volumes that don't have them. 4310 4311Put in support for e2fsck to recognize HURD specific ext2 features --- 4312most notably, the translator block. The e2fsprogs tools will now use 4313the creator_os field in the superblock to correctly handle different 4314OS-specific variants of the ext2 filesystem. 4315 4316E2fsck now fixes inodes which have a the deletion time set, but which 4317have a non-zero i_link_count field by offering to clear the deletion 4318time. Previously e2fsck assumed that the inode was deleted (per 0.3c 4319ext2 kernel behavior) and offered to unlink the file. 4320 4321If e2fsck sets the clean bit, but nothing else, set the exit code 4322FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it 4323set the filesystem valid bit when it was previously cleared. :-) This 4324was needed to make the HURD fsck driver happy. 4325 4326If the user refuses to attach an unattached inode, e2fsck will no 4327longer set the inode's link count. Otherwise, the inode would end up 4328getting marked as unused, which might cause loss of data later. 4329 4330Make the message issued by e2fsck when the superblock is corrupt less 4331confusing for users. It now mentions that another reason for the 4332"corrupt superblock" message might be that the partition might not be 4333an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.) 4334 4335Make the libext2 library more robuest so that e2fsck won't coredump on 4336an illegal superblock where the blocksize is zero. (f_crashdisk is 4337the test case). 4338 4339By default, create filesystems where the default checkinterval is 6 4340months (180 days). Linux servers can be robust enough that 20 reboots 4341can be a long, long time. 4342 4343Added configure flag --enable-old-bitops, which forces the bitops to 4344use the old (native) bitmask operations. By default on the sparc 4345platform, the standard ext2 bit ordering is now used. 4346 4347Added a new feature to e2fsck to byte-swap filesystems; this can be 4348used to convert old m68k filesystems to use the standard byte-order 4349storage for the superblock, inodes, and directory blocks. This 4350function is invoked by using the '-s' option to e2fsck. 4351 4352Debugfs's "dump" command has been enhanced so that it writes out the 4353exact size of the file so that the nulls at the end of the file are 4354eliminated. The command also accept a new "-p" option which will 4355attempt preserve to preserve the ownernship, permissions, and 4356file modification/access times. 4357 4358Debugfs has two new options, -f and -R. The -R option allows the user 4359to execute a single debugfs command from the command line. The -f 4360option allows the user to specify a "command file" containing debugfs 4361commands which will get executed. 4362 4363Dumpe2fs now pretty prints the check interval, instead of just 4364printing the check interval as a number of seconds. 4365 4366Fix bugs in debugfs: the params command when no filesystem is opened 4367no longer causes a core dump. It is now possible to unlink a file 4368when a pathame containing a '/' is specified. 4369 4370Tune2fs has a new -C option which sets the number of times the 4371filesystem has been mounted. 4372 4373Fix the chattr '-v' option so that it actually works. Chattr was 4374being buggy about the -v option parsing. 4375 4376Programmers' notes: 4377------------------- 4378 4379The directory lib/uuid contains a set of library routines to generate 4380DCE compatible UUIDs. 4381 4382Extended ext2fs_namei() to handle symbolic links. Added new function 4383ext2fs_nami_follow() which will follow last symbolic link in the case 4384where the pathname points to a sym link. 4385 4386The ext2fs_block_iterate function will now return the HURD translator 4387block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the 4388iterator to return data blocks only. The ext2fs.h file now defines 4389constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and 4390BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block 4391count field of the iterator callback function. 4392 4393The test script driver now takes an optional second argument, which is 4394the test case to be run. This allows you to run a test case without 4395needing to run the entire test suite. 4396 4397On Linux ELF systems, install the .so files in the correct places 4398(/usr/lib). The .so files must be stored in the same directory as the 4399.a files. 4400 4401Fixed miscellaneous HURD compilation issues with header file being 4402included in the right order. 4403 4404Fixed debugfs so that it resets optind to zero, not one, since setting 4405optind to zero is more correct. 4406 4407 4408E2fsprogs 1.04 (May 16, 1996) 4409============================= 4410 4411First "official" (1.03 was a limited release only) to support building 4412e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99 4413kernels). 4414 4415This package includes a RPM specs file, that it can be built using the 4416RedHat Package Manager. 4417 4418E2fsck now prints a hint that if there are lots of incorrectly located 4419inode bitmaps, block bitmaps, and inode table blocks, the user might 4420want to try using e2fsck -b 8193 first, to see if that fares any 4421better. 4422 4423For ext2 filesystem written with the hurd, debugfs will now print out 4424the translator field when printing an inode structure. 4425 4426Lots of miscellaneous linking/installation cleanups: 4427 4428 Libraries are now linked using a relative pathname, instead of 4429 relying on -L working correct. It doesn't, in many cases, including 4430 current versions of GNU ld. This guarantees that the build tree is 4431 linking with the right libraries, instead of the ones installed in 4432 /usr/lib. 4433 4434 Header files, man pages, and the et/ss shell scripts are now 4435 generated using a custom substitution script, instead of relying on 4436 the configure script. This prevents needless recompilation of 4437 files; in addition, the custom substitution script is much faster. 4438 4439 e2fsck may now be linked dynamically, by using the 4440 --enable-dynamic-e2fsck flag to configure. This is not recommended, 4441 since it increases e2fsck's dependence on other files, but some 4442 people need to save disk space, and other critical programs on their 4443 systems were being linked dynamically anyway. 4444 4445 Programs such as fsck which didn't need to be linked against 4446 libext2fs (or mke2fs which didn't need to be linked against libe2p) 4447 only link against libraries they actually need. Otherwise, those 4448 programs would require the presense of libraries that otherwise 4449 could be removed from a rescuse diskette. 4450 4451 The ss include files are now installed correctly so they can 4452 actually be used by another package. 4453 4454 If the profiling libraries are built, they are now installed on a 4455 "make install-libs". 4456 4457 4458E2fsprogs 1.03 (March 27, 1996) 4459=============================== 4460 4461Change the m68k bit numbering for bitmasks to match the bit numbering 4462used by all other ext2 implementations. (This change was requested by 4463the m68k kernel development team.) 4464 4465Support (in-development) filesystem format revision which supports 4466(among other things) dynamically sized inodes. 4467 4468Fixed a bug in the ext2 library so that an intelligent error is 4469returned if mke2fs is run with a ridiculously small number of blocks 4470for a partition. 4471 4472Fixed a bug in the ext2 library which required that the device be 4473openable in read/write mode in order to determine its size. This 4474caused e2fsck -n to require read/write access when it was not 4475previously necessary. 4476 4477Fixed a bug in e2fsck which casued it to occasionally fail the test 4478suite depending on which version of the floating point library it was 4479using. 4480 4481Fixed a bug in e2fsck so that it now halts with a fatal error when 4482certain superblock consistency checks fail. Previously it continued 4483running e2fsck, with some potential confusing/damaging consequences. 4484 4485Added new flag to fsck which allows the root to be checked in parallel 4486with other filesytems. This is not the safest thing in the world to 4487do, but some system administrators really wanted it. 4488 4489Fixed -Wall flames in lib/ss. 4490 4491 4492E2fsprogs 1.02 (January 16, 1996) 4493================================= 4494 4495Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels. 4496 4497Change e2fsck to print statistics of how many non-contiguous files are 4498on the system. Note that a file which is larger than 8k blocks, it is 4499guaranteed to be non-contiguous. 4500 4501In mke2fs, print a warning message if a user tries to format a whole 4502disk (/dev/hda versus /dev/hda1). If a user really wants to format a 4503whole disk, the -F (force) option forces mke2fs to format a whole disk 4504as a filesytem. 4505 4506Fix a bug in fsck where in some cases it might start checking 4507partitions in the next pass before it finishes checking partitions in 4508the current pass. This still won't cause two partitions on the same 4509disk will be checked, so it's rarely a problem in real life. 4510 4511Patch lsattr so that it won't hang when checking a named pipe. 4512 4513Minor compilation fixes: 4514 * Fix the order of libraries that were linked in debugfs. 4515 * Allow the sources to be compiled with -ansi turned on. 4516
