| Theodore Ts'o | 5a009bb | 2001-05-21 05:27:45 +0000 | [diff] [blame^] | 1 | E2fsprogs 1.20 (May 20, 2001) | 
| Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 2 | ============================= | 
| Theodore Ts'o | 5570a65 | 2000-08-21 01:23:39 +0000 | [diff] [blame] | 3 |  | 
| Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 4 | Add support for replaying the ext3 journal purely in user mode, | 
 | 5 | including handling the orphaned inode list.  Used code contributed by | 
 | 6 | Andreas Dilger, with bug fixes and the orphaned inode handling done | 
 | 7 | by Theodore Ts'o. | 
 | 8 |  | 
 | 9 | The mke2fs and tune2fs programs can create or modify a filesystem to | 
 | 10 | include an ext3 journal.  Tune2fs also can be used to remove an ext3 | 
 | 11 | journal from a filesystem. | 
| Theodore Ts'o | 5570a65 | 2000-08-21 01:23:39 +0000 | [diff] [blame] | 12 |  | 
 | 13 | E2fsck will now check for the existence of a linked list of orphan | 
 | 14 | inodes in the superblock, and clear those inodes before starting the | 
 | 15 | rest of the filesystem check (but after the journal playback). | 
 | 16 |  | 
| Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 17 | E2fsck now validates the file descriptor passed to the -C option, | 
 | 18 | which saves against the completion bar getting written to an | 
 | 19 | unexpected location, such as the disk being checked.  (Debian | 
 | 20 | bug/wishlist #55220) | 
 | 21 |  | 
 | 22 | E2fsck will now bump the filesystem revision number from zero to one | 
 | 23 | if any of the compatibility bits are set. | 
 | 24 |  | 
 | 25 | Fixed a bug where a badly corrupted directory on a big endian system | 
 | 26 | could cause e2fsck to die with a bus error.  The | 
 | 27 | ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in | 
 | 28 | the ext2 library now does alignment sanity checks on the rec_len field | 
 | 29 | of the directory entry before using it. | 
 | 30 |  | 
 | 31 | The ext2 library has been enhanced to make tune2fs safe to run on | 
 | 32 | mounted filesystems.  (Users could usually get away with using tune2fs | 
 | 33 | on mounted filesystems before, but with the advent of ext3 and | 
 | 34 | journaling, it became important to make tune2fs was *really* safe for | 
 | 35 | use even when the filesystem being modified is mounted.)  E2label is | 
 | 36 | now implemented by tune2fs using an argv[0] dispatch, so that e2label | 
 | 37 | is also now safe for use on mounted filesystems. | 
 | 38 |  | 
 | 39 | Added a new program, e2image, which creates a backup of critical ext2 | 
 | 40 | filesystem data structures.  The generated image file can be examined | 
 | 41 | using dumpe2fs and debugfs.  In the future, e2fsck will be able to use | 
 | 42 | the image file to help recover very badly damaged filesystems. | 
 | 43 |  | 
 | 44 | Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files | 
 | 45 | no longer cause e2fsck to bomb out.  Also treat files > 2GB as being | 
 | 46 | large file when deciding whether or not the filesystem has large files. | 
 | 47 |  | 
 | 48 | Fixed lsattr and chattr so that they work correctly on large files. | 
 | 49 | (Fixes Debian bug #72690.) | 
 | 50 |  | 
 | 51 | Removed limitation in get_device_size() which imposed a one terrabyte | 
 | 52 | filesystem limitation.  (Most 2.2 kernels still have a signed int | 
 | 53 | problem which cause 1 TB block device limitation.  Fortunately, the | 
 | 54 | kernel patches to fix this are much easier than fixing the 2TB | 
 | 55 | limitation in the kernel.  :-) | 
 | 56 |  | 
 | 57 | A max_mount_count of zero is now treated as if no mount count were | 
 | 58 | set.  (Previously, no mount count was indicated by using -1, and a | 
 | 59 | mount count of zero caused e2fsck to always be run.) | 
 | 60 |  | 
| Theodore Ts'o | 7764856 | 2001-05-14 13:04:44 +0000 | [diff] [blame] | 61 | Mke2fs supports two new filesystem types largefile and largefile4. | 
| Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 62 |  | 
 | 63 | Mke2fs now adds some randomness in s_max_mount_count so that multiple | 
 | 64 | filesystems won't be all checked at the same time under normal | 
 | 65 | operations. | 
 | 66 |  | 
| Theodore Ts'o | 5570a65 | 2000-08-21 01:23:39 +0000 | [diff] [blame] | 67 | Fixed bug in the progress bar printing code which could cause e2fsck | 
 | 68 | to core dump on an illegal filesystem. | 
 | 69 |  | 
| Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 70 | Fixed bug in fsck which could allow more than one instance of e2fsck | 
 | 71 | to be printing a progress bar.  (Debian bug #65267) | 
 | 72 |  | 
| Theodore Ts'o | 5570a65 | 2000-08-21 01:23:39 +0000 | [diff] [blame] | 73 | Fsck using a UUID or a LABEL specifier will work even if devfs is | 
 | 74 | compiled into the kernel and not mounted.  If the pathnames in | 
 | 75 | /proc/partitions are incorrect, fsck will search /dev for the correct | 
 | 76 | device (using the new ext2fs_find_block_device library function). | 
 | 77 | Fsck now also checks the RAID devices first so that they are properly | 
| Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 78 | found when they are in use.  Support has also been added to support | 
 | 79 | additional IDE disks and the DAC 960 device names.  (Debian bug #94159) | 
 | 80 |  | 
 | 81 | Fixed a bug in fsck which caused it not deal properly with 16 | 
 | 82 | byte long filesystem labels. | 
| Theodore Ts'o | 5570a65 | 2000-08-21 01:23:39 +0000 | [diff] [blame] | 83 |  | 
| Theodore Ts'o | 5a009bb | 2001-05-21 05:27:45 +0000 | [diff] [blame^] | 84 | Fsck's -t option has been made a lot more flexible.  The semantics for | 
 | 85 | what happens if a comma-separated list to fsck has been regularized, | 
 | 86 | and it is now possible to filter what filesystems will get checked | 
 | 87 | based what is in the filesystem's fstab entry's option field.  (Debian | 
 | 88 | bug #89483.) | 
 | 89 |  | 
| Theodore Ts'o | 5570a65 | 2000-08-21 01:23:39 +0000 | [diff] [blame] | 90 | The dumpe2fs program can now print out the group description | 
 | 91 | information in hex, and also prints the location of the superblock and | 
 | 92 | block group descriptor for those block groups that have them. | 
 | 93 |  | 
 | 94 | Mke2fs now clears the ext2 superblock before it starts creating a | 
 | 95 | filesystem, so that the superblock magic number is only written if the | 
 | 96 | filesystem creation process successfully completes. | 
 | 97 |  | 
 | 98 | The debugfs program's stat command now pretty-prints the blocks used | 
 | 99 | by an inode so that it's more compact and informative. | 
 | 100 |  | 
 | 101 | The debugfs stats command now uses the same libe2p code (which is used | 
 | 102 | by dumpe2fs) to print the superblock header information.  This is more | 
 | 103 | complete, and it avoids a bit of code duplication. | 
 | 104 |  | 
 | 105 | Added a new debugfs command, set_super_value (ssv) which allows the | 
 | 106 | user to set arbitrary superblock fields. | 
 | 107 |  | 
| Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 108 | Debugfs was extended to support inode numbers in hex (by prefixing | 
 | 109 | them with 0x), and so that modify_inode can set the inode generation | 
 | 110 | number.  Also, there is now a new function command called logdump | 
 | 111 | which will dump an ext3 journal. | 
 | 112 |  | 
 | 113 | Fixed a bug in debugfs so that quitting out of the pager doesn't kill | 
 | 114 | debugfs. | 
 | 115 |  | 
 | 116 | Debugfs's dump command now stops immediately upon reporting a disk | 
 | 117 | read error.  (Fixed a bug in ext2fs_file_read library routine which | 
 | 118 | caused debugfs not to stop.)  (Debian bug #79163) | 
 | 119 |  | 
 | 120 | On systems with /proc/mounts (mainly Linux systems), /proc/mounts is | 
 | 121 | checked before /etc/mtab is used, since /proc/mounts is more likely to | 
 | 122 | be accurate. | 
 | 123 |  | 
 | 124 | Added portability fixes for Solaris and Linux/ia64. | 
 | 125 |  | 
 | 126 | Various manual pages were clarified and cleaned up.  (Fixed debian | 
 | 127 | bugs #63442, #67446, and #87216) | 
 | 128 |  | 
| Theodore Ts'o | 5570a65 | 2000-08-21 01:23:39 +0000 | [diff] [blame] | 129 |  | 
 | 130 | Programmer's notes: | 
 | 131 | ------------------- | 
 | 132 |  | 
 | 133 | The e2fsck message printer now supports %Iu and %Ig, which will print | 
 | 134 | out the inode's user and group owners, respectively. | 
 | 135 |  | 
| Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 136 | E2fsprogs now includes its own version of include/linux/ext2_fs.h, so | 
 | 137 | that no longer dependent on the system having the correct version of | 
 | 138 | the kernel header files. | 
 | 139 |  | 
| Theodore Ts'o | 5570a65 | 2000-08-21 01:23:39 +0000 | [diff] [blame] | 140 | Added a new function to libext2, ext2fs_find_block_device(), which | 
 | 141 | searches the system (i.e., /dev, /devfs, /devices) for a pathname to a | 
 | 142 | device given its device number. | 
 | 143 |  | 
| Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 144 | Added a new function to libext2, ext2fs_sync_device, which centralizes | 
 | 145 | all of the places which might try to use the BLKFLSBUF or FDFLUSH | 
 | 146 | ioctls (and usually failing to define them since the system header | 
 | 147 | files don't usually do this for us, and we're trying to avoid usage of | 
 | 148 | kernel include files now). | 
 | 149 |  | 
| Theodore Ts'o | 5570a65 | 2000-08-21 01:23:39 +0000 | [diff] [blame] | 150 | Added new utility programs in tests/progs: random_exercise and | 
 | 151 | hold_inode.  They aren't built by default; they're useful for | 
 | 152 | exercising ext3 filesystem code. | 
 | 153 |  | 
| Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 154 | Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes | 
 | 155 | the filesystem close functions to only update the superblock, and to | 
 | 156 | not touch the block group descriptors.  Needed by tune2fs when | 
 | 157 | modifying a mounted filesystem. | 
 | 158 |  | 
 | 159 | Got rid of struct ext2fs_sb and replaced it with the standard struct | 
 | 160 | ext2_super_block from include/linux/ext2_fs.h.  Note: this may break | 
 | 161 | source (but not binary) compatibility of some users of the ext2 | 
 | 162 | library.  Those applications should just simply do a global search and | 
 | 163 | replace of struct ext2fs_sb with struct ext2_super_block, and use | 
 | 164 | their own private copy of ext2_fs.h if they aren't already. | 
 | 165 |  | 
 | 166 | The ino_t type has been renamed ext2_ino_t to protect applications | 
 | 167 | that attempt to compile -D_FILE_OFFSET_BITS=64, since this | 
 | 168 | inexplicably changes ino_t(!?).  So we use ext2_ino_t to avoid an | 
 | 169 | unexpected ABI change. | 
 | 170 |  | 
 | 171 | The Makefiles have been reworked so that "make check" can be run from | 
 | 172 | the top-level Makefile. | 
 | 173 |  | 
 | 174 | Fix general gcc -Wall complaints and removed dead code. | 
 | 175 |  | 
 | 176 | Remove use of NOARGS, because we assume everyone does ANSI C these | 
 | 177 | days. | 
 | 178 |  | 
 | 179 | Added build-rpm script from sct. | 
 | 180 |  | 
 | 181 | New functions ext2fs_image_{inode,super,bitmap}_{read,write} added  | 
 | 182 | to support e2image. | 
 | 183 |  | 
 | 184 | New function ext2fs_flush_icache which must be called if the | 
 | 185 | application program modifies the inode table blocks without going | 
 | 186 | through ext2fs_write_inode() interface. | 
 | 187 |  | 
 | 188 | New ext2fs_check_mount_point() function, which will return the mount | 
 | 189 | point of a device if mounted. | 
 | 190 |  | 
 | 191 | The io_channel abstraction now has an optional interface, | 
 | 192 | io_channel_write_range, which allows specific byte ranges to be | 
 | 193 | written.   | 
 | 194 |  | 
 | 195 | The unix_io IO channel now supports write-through caching, so that | 
 | 196 | journal creation is more efficient. | 
 | 197 |  | 
 | 198 | Added x86 assembly language routines to support byte swapping, to | 
 | 199 | reduce executable size. | 
 | 200 |  | 
 | 201 | Fixed bug in the utility program subst so that it's possible to | 
 | 202 | replace a substitution variable with a zero-length string. | 
 | 203 |  | 
 | 204 | Fixed numbering e2fsck pass1 problem numbers; an extra zero had | 
 | 205 | slipped into some of the problem number. |

| Theodore Ts'o | b777e26 | 2000-07-27 01:39:23 +0000 | [diff] [blame] | 207 | E2fsprogs 1.19 (July 13, 2000) | 
 | 208 | ============================== | 
| Theodore Ts'o | ab14676 | 2000-07-07 04:37:35 +0000 | [diff] [blame] | 209 |  | 
 | 210 | Release the resize2fs program since the timeout before it could | 
| Theodore Ts'o | 006ea71 | 2000-08-21 03:39:49 +0000 | [diff] [blame] | 211 | be released under the GPL has finally expired. | 
| Theodore Ts'o | ab14676 | 2000-07-07 04:37:35 +0000 | [diff] [blame] | 212 |  | 
 | 213 | Add experimental support needed for the ext2 compression patches. | 
 | 214 | This requires compiling e2fsprogs with the --enable-compression flag | 
 | 215 | to the configure script. | 
 | 216 |  | 
 | 217 | Added ext3 journalling support.  E2fsck will run the journal (if | 
 | 218 | necessary) by temporarily mounting the filesystem.  /sbin/fsck.ext3 is | 
 | 219 | installed as a symlink to e2fsck.  Fsck has been taught about ext3, | 
 | 220 | and treats it the same as ext2 in terms of the progress bar logic. | 
 | 221 | Dumpe2fs will display the superblock journaling information if the | 
 | 222 | filesystem has a journal.  The ext2 library will now permit opening an | 
 | 223 | ext3 filesystem with the recovery flag set.  This is necessary for | 
 | 224 | on-line dump's to work correctly, but there may be issues with this | 
 | 225 | working well since ext3 is much less agressive about syncing blocks to | 
 | 226 | the filesystem, since they're safe on the journal. | 
 | 227 |  | 
 | 228 | Tune2fs and e2fsck have been changed to allow the mount_count check to | 
 | 229 | be disabled by setting max_mount_count to -1.  (This was already | 
 | 230 | supported by the kernel.) | 
 | 231 |  | 
 | 232 | Create a symbolic link for fsck.ext3, since the e2fsprogs utilities | 
 | 233 | are used for ext3 as well. | 
 | 234 |  | 
 | 235 | Added internationalization support for e2fsprogs; must be enabled | 
 | 236 | by passing --enable-nls to configure. | 
 | 237 |  | 
 | 238 | Always use the provided ext2fs header files to insulate ourselves from | 
 | 239 | kernel version changes.  Which include files are used by e2fsprogs | 
 | 240 | have also been cleaned up to improve portability. | 
 | 241 |  | 
 | 242 | Limit the number of times that e2fsck updates the progress bar so that | 
 | 243 | people who are booting using a 9600 baud console don't get swampped by | 
 | 244 | too many updates. | 
 | 245 |  | 
 | 246 | Improved the loop detection algorithm in e2sck's pass #3 so that it is | 
 | 247 | much, much faster for large filesystems with a large number of | 
 | 248 | directories. | 
 | 249 |  | 
 | 250 | The memory footprint for e2fsck is now slightly smaller than before. | 
 | 251 |  | 
 | 252 | E2fsck now checks if special devices have a non-zero size, and offers | 
 | 253 | to clear the size field if it finds such an inode.   | 
 | 254 |  | 
 | 255 | E2fsck now checks if special devices have the append-only flag set, | 
 | 256 | and offers to clear the inode. | 
 | 257 |  | 
 | 258 | E2fsck now properly handles some "should never fail" cases during a | 
 | 259 | bitmap copy in pass5. | 
 | 260 |  | 
 | 261 | E2fsck now properly prints control characters in filenames as ^A .. ^Z. | 
 | 262 |  | 
| Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 263 | E2fsck now calculates the correct location of the backup superblock in | 
 | 264 | the case of filesystem blocksizes > 1k. | 
 | 265 |  | 
 | 266 | Fixed a bug in e2fsck's calculation of the number of inodes_per_block | 
 | 267 | which normally didn't cause problems under most filesystem parameters, | 
 | 268 | but could cause a valid superblock to be rejected in extreme cases. | 
 | 269 | Other checks for validating superblock values were made more | 
 | 270 | stringent. | 
 | 271 |  | 
| Theodore Ts'o | ab14676 | 2000-07-07 04:37:35 +0000 | [diff] [blame] | 272 | Added non-destructive write testing to the badblocks program, courtesy | 
 | 273 | of David Beattie.  The badblocks also now has an option to input the | 
 | 274 | current set of bad blocks, so that known bad blocks are skipped to | 
 | 275 | speed up the badblocks test.  There is also a persistent rescan | 
| Theodore Ts'o | 006ea71 | 2000-08-21 03:39:49 +0000 | [diff] [blame] | 276 | feature which causes badblocks to run until it has completed some | 
 | 277 | number of passes without discovering any new bad blocks. | 
| Theodore Ts'o | ab14676 | 2000-07-07 04:37:35 +0000 | [diff] [blame] | 278 |  | 
 | 279 | Badblocks now checks to see if the device is mounted and refuses to do | 
 | 280 | the tests involving writing to the device if it is mounted.  Also, | 
 | 281 | badblocks now allows the number of blocks to be checked to be | 
 | 282 | defaulted to the size of the partition. | 
 | 283 |  | 
 | 284 | Fixed a bug in fsck which didn't allow non-root users to be able to | 
 | 285 | check filesystems if there were any LABEL= or UUID= entries in | 
 | 286 | /etc/fstab. | 
 | 287 |  | 
 | 288 | The Hurd doesn't support the filetype filesystem feature.  The mke2fs | 
 | 289 | program now makes sure that for the Hurd, the filestype feature is | 
 | 290 | turned off.  E2fsck will check to see if the filetype feature is | 
 | 291 | turned on for Hurd filesystems, and offer to turn off the feature. | 
 | 292 |  | 
 | 293 | Mke2fs now has a safety check to make sure the number of blocks do not | 
 | 294 | exceed 32 bits even on a 64 bit platform. | 
 | 295 |  | 
 | 296 | Really fixed a bug in fsck to allow "fsck -As" to run interactive | 
 | 297 | fsck's.  (For those people who like to do interactive fsck's in the | 
 | 298 | /etc/rc scripts!?!) | 
 | 299 |  | 
 | 300 | Debugfs has a few new features: the rdump command, which will do a | 
 | 301 | recursive dump of a directory and all of its contents, and the lcd | 
 | 302 | command which does a local chdir (much like the ftp command of the | 
 | 303 | same name).  In addition, the debugfs program and the open_filesystem | 
 | 304 | command now takes three new options: -b and -s, which allows the | 
 | 305 | blocksize and superblock location to be specified, and the -c option | 
 | 306 | which is used in catastrophic situations where the block group | 
 | 307 | descriptors are corrupt.  If the -c option is specified, debugfs will | 
 | 308 | skip trying to read in the block and inode bitmaps. | 
 | 309 |  | 
 | 310 | Debufs's lsdel command was fixed to handle bad blocks in the inode | 
 | 311 | table. | 
 | 312 |  | 
 | 313 | A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use | 
 | 314 | 4 digit years. | 
 | 315 |  | 
 | 316 | General improvements in error messages | 
 | 317 |  | 
 | 318 |   - Mke2fs prints a sane error message if the partition size is zero | 
 | 319 | 	(usually because the partition table wasn't reread by the | 
 | 320 | 	kernel due to the partition being busy), instead of "invalid | 
 | 321 | 	argument passed to ext2 library while initializing superblock". | 
 | 322 |  | 
 | 323 |   - Fsck now prints more self-explanatory message if an invalid UUID= | 
 | 324 | 	or LABEL= specification is passed to it. | 
 | 325 |  | 
 | 326 | UUID library changed to use the LGPL. | 
 | 327 |  | 
 | 328 | Fixed a bug in the UUID library where very rapid calls to the | 
 | 329 | time-based UUID generator could cause duplicate UUID's to be returned. | 
 | 330 | This was not a problem for e2fsprogs, but it could be a problem for | 
 | 331 | other users of the library. | 
 | 332 |  | 
 | 333 | Make the UUID library more robust in the face of missing or an | 
 | 334 | improper /dev/urandom or /dev/random files. | 
 | 335 |  | 
 | 336 | Added some random portability fixes for Solaris. | 
 | 337 |  | 
 | 338 | Some minor man page updates. | 
 | 339 |  | 
 | 340 | Fixed a memory leak in the ss library. | 
 | 341 |  | 
 | 342 |  | 
 | 343 | Programmer's notes: | 
 | 344 | ------------------- | 
 | 345 |  | 
 | 346 | We now try to use lseek64 and open64 from the LFS if possible. | 
 | 347 |  | 
 | 348 | The 3rd parameter in e2p's print_flags is now a flags word, instead of | 
 | 349 | a boolean option. | 
 | 350 |  | 
 | 351 | The mark and unmark bitmap functions now return the previous state of | 
 | 352 | the bit that was being changed, which is useful for some speed | 
 | 353 | optimizations. | 
 | 354 |  | 
 | 355 | The following functions have been added to enhance the badblocks list | 
 | 356 | handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and | 
 | 357 | ext2fs_badblocks_equal. | 
 | 358 |  | 
 | 359 | The ext2 header files now have the latest journalling fields to the | 
 | 360 | superblock. | 
 | 361 |  | 
 | 362 | The ext2fs_mkdir function in libext2fs now properly backs out of error | 
 | 363 | conditions robustly. | 
 | 364 |  | 
 | 365 | Cleaned up makefiles: | 
 | 366 |   - to cleanly  compile with the -j flag. | 
 | 367 |   - so distclean removes all generated files. | 
 | 368 |   - so in case of an error while installing header files, the make aborts. | 
 | 369 |  | 
 | 370 | Fix test_script so that it works correctly when compiling in the | 
 | 371 | source directory. | 
 | 372 |  | 
| Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 373 | The random UUID generation routine has been made slightly better in | 
 | 374 | the case where /dev/random doesn't exist.  (Use of randomly-based UUID | 
 | 375 | is still not recommended if /dev/random doesn't exist, however; it's | 
 | 376 | better to use the time/ethernet MAC address UUID in this case.) | 
| Theodore Ts'o | ab14676 | 2000-07-07 04:37:35 +0000 | [diff] [blame] | 377 |  | 
 | 378 | Clean up the build process so it's more friendly in case of missing | 
 | 379 | directories. | 
 | 380 |  | 
 | 381 | The ext2fs header file can now be #include'd into C++ programs. | 
 | 382 |  | 
 | 383 | The e2p.h header file is now installed. | 
 | 384 |  | 
 | 385 | Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds. | 
 | 386 |  |

 | 390 | ================================== | 
 | 391 |  | 
 | 392 | Fix a core dumping bug in e2fsck if an imagic inode is present or | 
 | 393 | (more rarely) if the filesystem is badly corrupted enough that e2fsck | 
 | 394 | has to restart pass 1 processing.  E2fsck now closes the filesystem | 
 | 395 | before freeing a large number of its data structures, so in the case | 
 | 396 | of future memory faults, at least the fixed filesystem will be fully | 
 | 397 | written out. | 
 | 398 |  | 
 | 399 | If a filesystem doesn't support imagic inodes, and e2fsck discovers an | 
 | 400 | imagic inode, it will offer to clear the imagic flag. | 
 | 401 |  | 
 | 402 | E2fsck will now offer to clear the immutable flag on special files | 
 | 403 | (device/socket/fifos) when running it in non-preen mode. | 
 | 404 |  | 
 | 405 | E2fsck will now set the filetype when creating /lost+found, and when | 
 | 406 | connected orphaned inodes to /lost+found. | 
 | 407 |  | 
 | 408 | Debugfs's ncheck and icheck commands now handles the case where there | 
 | 409 | are bad blocks in the inode table without bombing out. | 
 | 410 |  | 
 | 411 | The badblocks list processing code has been made more efficiently for | 
 | 412 | appending a large number of (ordered) badblocks to the badblocks list. | 
 | 413 |  | 
 | 414 | Some minor man page updates. | 
 | 415 |  | 
 | 416 | Fsck now allows interactive e2fsck's when using fsck -As (not a common | 
 | 417 | mode, but some people like to do this in boot scripts for silly reasons). | 
 | 418 |  | 
 | 419 | Programmer's notes: | 
 | 420 | ------------------- | 
 | 421 |  | 
 | 422 | The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet | 
 | 423 | with the problem code convention. | 
 | 424 |  | 
 | 425 | The badblocks list regression test program has been updated to work | 
 | 426 | with previously made API name changes. | 
 | 427 |  | 
 | 428 | The ext2fs_free() command now uses the new badblocks API to avoid | 
 | 429 | using the compatibility layer. | 
 | 430 |  | 
 | 431 | Added new regression test cases; the run_e2fsck test script now | 
 | 432 | supports the ability for a test case to run a prepratory command | 
 | 433 | before running e2fsck. | 
 | 434 |  | 
| Theodore Ts'o | 28e1194 | 1999-10-26 18:17:20 +0000 | [diff] [blame] | 435 | E2fsprogs 1.17 (October 26, 1999) | 
 | 436 | ================================= | 
 | 437 |  | 
 | 438 | Fixed nasty typo in fsck which caused parallelized fsck's to go into an | 
 | 439 | infinite loop. | 
 | 440 |  | 
 | 441 | Fixed a bug in fsck where it used strncmp to compare a binary UUID, | 
 | 442 | thus potentially causing problems if a binary UUID contained a NULL | 
 | 443 | character. | 
 | 444 |  | 
 | 445 | E2fsck now uses stricter checks for directory entries in pass 2: | 
 | 446 | zero-length filenames are not allowed; neither are 8 byte long | 
 | 447 | directory entries. | 
 | 448 |  | 
 | 449 | The debugfs "dirty" command now clears the filesystem valid bit. | 
 | 450 | (Previously this just set the dirty-as-in-needs-writing-out-to-disk | 
 | 451 | bit in the in-core superblock image.  The new functionality is more | 
 | 452 | what the user expects, and is more useful.) | 
 | 453 |  | 
 | 454 | Added a debugging hook to test parallel fsck; if the environment | 
 | 455 | variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive | 
 | 456 | will be checked in parallel when they normally would not be. | 
 | 457 |  | 
 | 458 | Programmer's notes: | 
 | 459 | ------------------- | 
 | 460 |  | 
 | 461 | Fixed some #ifdef's for compilation under the Hurd OS. | 
 | 462 |  | 
 | 463 | Fixed minor W2K compatibility problems. | 
 | 464 |  | 
 | 465 | Fixed some miscellaneous GCC warnings. | 
 | 466 |  | 
 | 467 |  | 
| Theodore Ts'o | 8a31ffe | 1999-10-23 03:33:15 +0000 | [diff] [blame] | 468 | E2fsprogs 1.16 (October 22, 1999) | 
 | 469 | ================================= | 
 | 470 |  | 
 | 471 | Fixed a race condition bug in fsck; when printing a progress bar, if | 
 | 472 | checking multiple filesystems in parallel, it was possible for fsck to | 
 | 473 | send e2fsck a SIGUSR1 signal before e2fsck had installed its signal | 
 | 474 | handler, which would cause it to terminate with a signal 10. | 
 | 475 |  | 
 | 476 | E2fsck now properly handles filesystems that have the | 
 | 477 | INCOMPAT_FILETYPE feature turned on.  It can be used to convert a | 
 | 478 | filesystem into using or not using FILETYPE feature. | 
 | 479 |  | 
 | 480 | E2fsck now properly handles filesystems that have the IMAGIC feature | 
 | 481 | turned on (this is used on Linux AFS servers). | 
 | 482 |  | 
 | 483 | The mke2fs program now creates filesystems that have the filetype and | 
 | 484 | sparse_superblock features enabled by default, unless it is run on a | 
 | 485 | pre-2.2 kernel.  These features are not supported by a pre-2.2 kernel, | 
 | 486 | so there is now a new flag -O which allows the user to specify with | 
 | 487 | which features she would like to create the filesystem; "mke2fs -O | 
 | 488 | none" will create a filesystsem compatible with 2.0 kernels. | 
 | 489 |  | 
 | 490 | The tune2fs program now has a -O option which allows the user to set | 
 | 491 | and reset "safe" filesystem features.  Currently, the only ones which | 
 | 492 | allows to be modified are the filetype and sparse_superblock features. | 
 | 493 | Note setting or clearing either feature will require running e2fsck on | 
 | 494 | the filesystem afterwards.  (n.b. Clearing the sparse_superblock feature | 
 | 495 | requires that there is enough free space on the filesystem for the | 
 | 496 | extra superblocks which will be created by e2fsck.) | 
 | 497 |  | 
 | 498 | Debugfs can now set and print filesystem features in the superblock | 
 | 499 | using the "features" command.  Dumpe2fs will print out the complete | 
 | 500 | set of features when listing the superblock. | 
 | 501 |  | 
 | 502 | Dumpe2fs has new options -f (force) and -h (header-only). | 
 | 503 |  | 
 | 504 | Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead | 
 | 505 | message to come up.  This could happen when decrementing or | 
 | 506 | incrementing a link count could result in an overflow. | 
 | 507 |  | 
 | 508 | Fixed a bug in e2fsck where the block count on the lost+found | 
 | 509 | directory would not be properly incremented when the directory was | 
 | 510 | expanded to the point where an indirect block needed to be allocated. | 
 | 511 |  | 
 | 512 | E2fsck now makes some additional sanity checks on the superblock to | 
 | 513 | avoid crashing or giving a memory allocation error if some of the | 
 | 514 | values in the superblock are unresonable (but the superblock otherwise | 
 | 515 | looks valid). | 
 | 516 |  | 
 | 517 | Fixed a bug in e2fsck where a very badly corrupted filesystem might | 
 | 518 | require two passes to completely fix the filesystem.  This happened if | 
 | 519 | an inode claimed blocks that was part of the filesystem metadata | 
 | 520 | (typically, when garbage was written into an inode table or indirect | 
 | 521 | block, since this kind of filesystem corruption normally doesn't | 
 | 522 | happen otherwise). | 
 | 523 |  | 
 | 524 | On the Alpha, glibc declares st_flags although it isn't actually used; | 
 | 525 | the configure script was improved to detect this case so that | 
 | 526 | e2fsprogs can avoid using the non-functional stat field. | 
 | 527 |  | 
 | 528 | The manual pages were updated to use a more consistent formatting | 
 | 529 | style consistent with standard Unix man pages.  Mke2fs's man page | 
 | 530 | added documentation for a few previously undocumented options. | 
 | 531 |  | 
 | 532 | Fixed minor display bugs in tune2fs and mke2fs. | 
 | 533 |  | 
 | 534 | Programmer's notes: | 
 | 535 | ------------------- | 
 | 536 |  | 
 | 537 | Improved portability of e2fsprogs to non-Unix systems (in particular, NT). | 
 | 538 |  | 
 | 539 | Added features to parse and print feature strings into the e2p library.   | 
 | 540 | (e2p_feature2string, e2p_string2feature, e2p_edit_feature). | 
 | 541 |  | 
 | 542 | ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories | 
 | 543 | whose directory entries contain proper filetype information if the | 
 | 544 | filesystem supports it. | 
 | 545 |  | 
 | 546 | ext2fs_link() now uses the low 3 bits of its flags parameter to pass | 
 | 547 | the directory entry filetype information.  This is used to set the | 
 | 548 | directory entry filetype information if the filesystem supports it. | 
 | 549 |  | 
 | 550 | Fixed a bug in ext2fs_expand_dir() where the block count in a | 
 | 551 | directory's inode would not be properly incremented when the directory | 
 | 552 | was expanded to the point where an indirect block needed to be | 
 | 553 | allocated. | 
 | 554 |  |

| Theodore Ts'o | e2a99be | 1999-07-19 15:48:08 +0000 | [diff] [blame] | 557 | ============================== | 
| Theodore Ts'o | 6d53db3 | 1999-07-03 20:52:21 +0000 | [diff] [blame] | 558 |  | 
 | 559 | Add configuration checks so that e2fsprogs will compile cleanly on | 
 | 560 | Linux 2.3 kernels that have renamed i_version to i_generation. | 
 | 561 |  | 
| Theodore Ts'o | e2a99be | 1999-07-19 15:48:08 +0000 | [diff] [blame] | 562 | E2fsck now prints a progress/completion bar (and not just a simple | 
 | 563 | spinner) if the -C0 option is requested or if it receives a SIGUSR1 | 
 | 564 | signal.  Fsck will automatically manage the (potentially muliple) | 
 | 565 | e2fsck processes to print completion bars if it is given a -C option, | 
 | 566 | with the right thing happening if multiple filesystems are being | 
 | 567 | checked in parallel. | 
 | 568 |  | 
 | 569 | Mke2fs now has better automatic hueristics to determine the filesystem | 
 | 570 | parameters to be used for a particular filesystem.  Added a new option | 
 | 571 | -T which allows the user to specify how the filesystem is to be used, | 
 | 572 | which helps mke2fs do a better job selecting the filesystem parameters. | 
 | 573 |  | 
| Theodore Ts'o | a39f3ef | 1999-07-20 02:02:40 +0000 | [diff] [blame] | 574 | Mke2fs now creates revision 1 filesystems by default, and with the | 
 | 575 | sparse superblock feature enabled.  The sparse superblock feature is | 
| Theodore Ts'o | 8a31ffe | 1999-10-23 03:33:15 +0000 | [diff] [blame] | 576 | not understood by Linux 2.0 kernels, so they will only allow read-only | 
 | 577 | mounts of filesystems with this sparse superblocks. | 
| Theodore Ts'o | a39f3ef | 1999-07-20 02:02:40 +0000 | [diff] [blame] | 578 |  | 
| Theodore Ts'o | 6d53db3 | 1999-07-03 20:52:21 +0000 | [diff] [blame] | 579 | Fix bug where if /dev/null couldn't be opened (should never happen), | 
 | 580 | e2fsck would hang in a tight loop. | 
 | 581 |  | 
 | 582 | Make e2fsck handle the case where /lost+found isn't a directory. | 
 | 583 |  | 
 | 584 | E2fsck now uses mallinfo if it exists to get accurate statistics about | 
 | 585 | its memory usage. | 
 | 586 |  | 
 | 587 | Fix bug in e2fsck where it wouldn't check to see if a disconnected | 
 | 588 | inode had any problems before connecting it to /lost+found. | 
 | 589 |  | 
 | 590 | Add check to e2fsck so it makes sure that total number of inodes in | 
 | 591 | the filesystem is a sane number. | 
 | 592 |  | 
 | 593 | Fix fencepost error when clearing an the end of the block bitmap which | 
 | 594 | caused the last block in the bitmap not to get cleared. | 
 | 595 |  | 
 | 596 | Cleaned up a number of messages in e2fsck: | 
 | 597 | 	* The message "Group's #'s copy of the group descriptor..." | 
 | 598 | 		was fixed so that the correct number would be displayed. | 
 | 599 | 	* Added missing space in the "disk write-protected" error messsage | 
 | 600 | 	* Cleaned up the error message printed when a non-interactive | 
 | 601 | 		e2fsck needs to abort a check because the filesystem | 
 | 602 | 		appears to be mounted. | 
 | 603 |  | 
 | 604 | Added a new command-line utility, uuidgen, which will create and print | 
 | 605 | a UUID. | 
 | 606 |  | 
 | 607 | Make debugfs's icheck command more robust by checking to make sure an | 
 | 608 | inode has valid blocks before interarting over the inode's blocks. | 
 | 609 |  | 
 | 610 | UUID generation now uses a random-based scheme whenever possible to | 
 | 611 | prevent potential privacy problems. | 
 | 612 |  | 
 | 613 | Man pages for all of the UUID functions in the lirbary were added. | 
 | 614 |  | 
 | 615 | Fixed bug in fsck so it won't coredump if a filesystem not in | 
 | 616 | /etc/fstab is given to it. | 
 | 617 |  | 
 | 618 | Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab | 
 | 619 | that most of the other mount utilities understands. | 
 | 620 |  | 
 | 621 | Mke2fs will make a filesystem even if it appears mounted if the force | 
 | 622 | option is given. | 
 | 623 |  | 
 | 624 | Dumpe2fs has new command-line options which allow a filesystem expert | 
 | 625 | to specify the superblock and blocksize when opening a filesystem. | 
 | 626 | This is mainly useful when examining the remains of a toasted | 
 | 627 | filesystem. | 
 | 628 |  | 
 | 629 | The badblocks program has been updated to display correctly on disks | 
 | 630 | with large block numbers. | 
 | 631 |  | 
| Theodore Ts'o | e2a99be | 1999-07-19 15:48:08 +0000 | [diff] [blame] | 632 | The badblocks program no longer gives spurious errors when errors | 
 | 633 | occur on non-block boundaries, which is common if the blocksize is | 
 | 634 | larger than 1k. | 
 | 635 |  | 
| Theodore Ts'o | 6d53db3 | 1999-07-03 20:52:21 +0000 | [diff] [blame] | 636 | Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the | 
 | 637 | MKE2FS_SYNC environment variable is set.  This is to work around a VM | 
 | 638 | bug in the 2.0 kernel.  I've heard a report that a RAID user was able | 
| Theodore Ts'o | a39f3ef | 1999-07-20 02:02:40 +0000 | [diff] [blame] | 639 | to trigger it even using a 2.2 kernel, but hopefully it will not be | 
 | 640 | needed for most Linux 2.2 users. | 
| Theodore Ts'o | 6d53db3 | 1999-07-03 20:52:21 +0000 | [diff] [blame] | 641 |  | 
 | 642 | Fixed miscellaneous documentation and man pages. | 
 | 643 |  | 
 | 644 | Programmer's notes: | 
 | 645 | ------------------- | 
 | 646 |  | 
 | 647 | Cleaned up functions such as pass1_get_blocks, pass1_read_inode which | 
 | 648 | in e2fsck's pass1.c really should have been static. | 
 | 649 |  | 
 | 650 | The return value of the uuid_compare() function was changed to make it | 
 | 651 | match with the convetions used by strcmp, memcmp, and Paul Leach's | 
 | 652 | UUID sample document. | 
 | 653 |  | 
 | 654 | The "make depend" process has now been made more automated; it now | 
 | 655 | automatically word-wraps the dependencies, and only replaces source | 
 | 656 | Makefile.in if there has been a change in the dependencies.  Also, a | 
 | 657 | top-level "make depend" now recurses through all the subdirectories | 
 | 658 | automatically. | 
 | 659 |  | 
 | 660 | The Makefile in .../util has been changed so that subst is built using | 
 | 661 | the native C compiler during a cross-compilation, since the subst | 
 | 662 | program is only used during the build process.  Also add an explicit | 
 | 663 | rule to build util/subst by cd'ing to the correct directory and | 
 | 664 | running Makefile. | 
 | 665 |  | 
 | 666 | The man directories are defined in terms mandir, so that the configure | 
 | 667 | script can override the location of the manual pages. | 
 | 668 |  | 
 | 669 | The config files have been updated to recognize new machine types for | 
 | 670 | both the i386 and alpha families. | 
 | 671 |  | 
 | 672 | Fsck has been modified so that it will accurately create an | 
 | 673 | fsck_instance even when the noexecute flag is set.  This allows for | 
 | 674 | accurate debugging of the fsck pass structure.  Also, when the verbose | 
 | 675 | flag is given twice, fsck will print debugging information about when | 
 | 676 | fsck is waiting for jobs to finish. | 
 | 677 |  |

| Theodore Ts'o | 14790ed | 1999-01-12 23:32:52 +0000 | [diff] [blame] | 679 | E2fsprogs 1.14 (January 9, 1999) | 
 | 680 | ================================ | 
 | 681 |  | 
 | 682 | Fix the fstab parsing code so that it can handle blank lines and | 
 | 683 | comment characters.  Also, missing pass numbers need to be treated as | 
 | 684 | zero. | 
 | 685 |  | 
 | 686 | Fixed a bug in e2fsck where under some circumstances (when e2fsck | 
 | 687 | needs to restart processing after fixing an egregious inconsistency) | 
 | 688 | it would try to access already freed memory. | 
 | 689 |  | 
 | 690 | E2fsck now prints non-printable characters in directory entries and | 
 | 691 | pathnames using '^' and 'M-' notation. | 
 | 692 |  | 
 | 693 | Fixed chattr so that it will ignore symbolic links when doing | 
 | 694 | recursive descent traversals.  For both chattr and lsattr, no longer | 
 | 695 | print the version string unless the -V option is given. | 
 | 696 |  | 
 | 697 | Allow the system administrator to directly specify the number of | 
 | 698 | inodes desired in the filesystem, for some special cases where this is | 
 | 699 | necessary. | 
 | 700 |  | 
 | 701 | Fix portability problems so that e2fsprogs can be compiled under Linux | 
 | 702 | 1.2 systems and Solaris systems. | 
 | 703 |  | 
 | 704 | Update the config.guess file with a more recent version that will | 
 | 705 | identify newer Linux platforms. | 
 | 706 |  | 
 | 707 | Programmer's notes | 
 | 708 | ------------------ | 
 | 709 |  | 
 | 710 | Ext2fs_read_inode and ext2fs_write_inode will now return an error if | 
 | 711 | an inode number of zero is passed to them. |

| Theodore Ts'o | 556ad13 | 1998-12-19 08:10:58 +0000 | [diff] [blame] | 713 | E2fsprogs 1.13 (December 15, 1998) | 
 | 714 | ================================== | 
 | 715 |  | 
 | 716 | Fixed a bug in debugfs where an error messages weren't getting printed | 
 | 717 | when the ext2 library routines to read inodes returned errors in the | 
 | 718 | stat, cmri and rm commands. | 
 | 719 |  | 
 | 720 | Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is | 
 | 721 | provided, it won't create an inode table smaller than the minimum | 
 | 722 | number of inodes required for a proper ext2 filesystem. | 
 | 723 |  | 
 | 724 | Fsck now parses the /etc/fstab file directly (instead of using | 
 | 725 | getmntent()), so that it can distinguish between a missing pass number | 
 | 726 | field and pass number field of zero.  This caused problems for | 
 | 727 | diskless workstations where all of the filesystems in /etc/fstab have | 
 | 728 | an explicit pass number of zero, and fsck could not distinguish this | 
 | 729 | from a /etc/fstab file with missing pass numbers. | 
 | 730 |  | 
 | 731 | E2fsck will create a /lost+found directory if there isn't one in the | 
 | 732 | filesystem, since it's safer to create the lost+found directory before | 
 | 733 | it's needed. | 
 | 734 |  | 
 | 735 | Fixed e2fsck so that it would detect bogus immutable inodes which | 
 | 736 | happen to be sockets and FIFO files, and offer to clear them. | 
 | 737 |  | 
 | 738 | If a filesystem has multiple reasons why it needs to be checked, and | 
 | 739 | one of the reasons is that it is uncleanly mounted, e2fsck will print | 
 | 740 | that as the reason why the filesystem is being checked. | 
 | 741 |  | 
 | 742 | Cleaned up the output routines of mke2fs so that it doesn't overflow | 
 | 743 | an 80 column display when formating really big filesystems. | 
 | 744 |  | 
 | 745 | Added a sanity check to e2fsck to make sure that file descriptors 0, | 
 | 746 | 1, 2 are open before opening the hard disk.  This avoids a problem | 
 | 747 | where a broken program might exec e2fsck with those file descriptors | 
 | 748 | closed, which would cause disastrous results if the kernel returns a | 
 | 749 | file descriptor for the block device which is also used by FILE * | 
 | 750 | stdout. | 
 | 751 |  | 
 | 752 | Fixed up the e2fsck progress reporting functions so that the values | 
 | 753 | reliably reach 100% at the completion of all of the e2fsck passes. | 
 | 754 |  | 
 | 755 | Fixed minor documentation bugs in man pages and usage messages. | 
 | 756 |  | 
 | 757 | Programmer's notes: | 
 | 758 | ------------------- | 
 | 759 |  | 
 | 760 | Fixed a number of lint warnings in the ext2fs library and potential | 
 | 761 | portability problems from other OS's header files that might define | 
 | 762 | CPP macros for names like "max" and "min". | 
 | 763 |  | 
 | 764 | ext2fs_badblocks_list_add() has been made more efficient when it needs | 
 | 765 | to grow the bad blocks list. | 
 | 766 |  | 
 | 767 | Fixed a bug in e2fsck which caused it to dereference a freed pointer | 
 | 768 | just before exiting. | 
 | 769 |  | 
 | 770 | Fixed the substition process for generating the mk_cmds and compile_et | 
 | 771 | scripts so that they will work outside of the build tree. | 
 | 772 |  | 
 | 773 | Add sanity check to e2fsck so that if an internal routine | 
 | 774 | (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer | 
 | 775 | and causing a core dump.  This should never happen, but... |

| Theodore Ts'o | a569671 | 1998-07-09 05:38:07 +0000 | [diff] [blame] | 777 | E2fsprogs 1.12 (July 9, 1998) | 
| Theodore Ts'o | 21d5385 | 1998-02-21 03:14:50 +0000 | [diff] [blame] | 778 | ================================== | 
 | 779 |  | 
 | 780 | E2fsprogs now works with glibc (at least with the version shipped wtih | 
 | 781 | RedHat 5.0).  The ext2fs_llseek() function should now work even with | 
 | 782 | i386 ELF shared libraries and if llseek() is not present.  We also | 
 | 783 | explicitly do a configure test to see if (a) llseek is in libc, and | 
 | 784 | (b) if llseek is declared in the system header files.  (See standard | 
 | 785 | complaints about libc developers don't understand the concept of | 
 | 786 | compatibility with previous versions of libc.) | 
 | 787 |  | 
| Theodore Ts'o | c9833a6 | 1998-07-05 19:37:53 +0000 | [diff] [blame] | 788 | The ext2fs library now writes out the block group number in each of | 
 | 789 | the superblock copies.  This makes it easier to automatically | 
 | 790 | determine the starting block group of the filesystem when the block | 
 | 791 | group information is trashed. | 
 | 792 |  | 
 | 793 | Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature, | 
| Theodore Ts'o | 101c84f | 1998-03-24 16:27:11 +0000 | [diff] [blame] | 794 | which means that e2fsprogs will ignore the high 8 bits of the | 
 | 795 | directory entry's name_len field, so that it can be used for other | 
 | 796 | purposes. | 
 | 797 |  | 
 | 798 | Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature. | 
 | 799 | E2fsprogs will now support filesystems with 64-bit sized files. | 
 | 800 |  | 
 | 801 | Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature. | 
 | 802 |  | 
| Theodore Ts'o | 21d5385 | 1998-02-21 03:14:50 +0000 | [diff] [blame] | 803 | Added new program "e2label", contributed by Andries Brouwer.  E2label | 
 | 804 | provides an easy-to-use interface to modify the filesystem label. | 
 | 805 |  | 
| Theodore Ts'o | a4b2d3c | 1998-04-03 16:12:25 +0000 | [diff] [blame] | 806 | Fixed bug so that lsattr -v works instead of producing a core dump. | 
 | 807 |  | 
| Theodore Ts'o | 21d5385 | 1998-02-21 03:14:50 +0000 | [diff] [blame] | 808 | Fixed a minor bug in mke2fs so that all groups with bad superblock | 
 | 809 | backup blocks are printed (not just the first one). | 
| Theodore Ts'o | a4b2d3c | 1998-04-03 16:12:25 +0000 | [diff] [blame] | 810 |  | 
 | 811 | Mke2fs will check the size of the device, and if the user specifies a | 
 | 812 | filesystem size larger than the apparent size of the device it will | 
 | 813 | print a warning message and ask if the user wants to proceed. | 
 | 814 |  | 
| Theodore Ts'o | c9833a6 | 1998-07-05 19:37:53 +0000 | [diff] [blame] | 815 | E2fsck has a new option -C, which sends completion information to the | 
 | 816 | specified file descriptor.  For the most part, this is intended for | 
 | 817 | programs to use, although -C 0 will print a spinning character to the | 
 | 818 | stdout device, which may be useful for users who want to see something | 
 | 819 | happening while e2fsck goes about its business. | 
 | 820 |  | 
| Theodore Ts'o | 21d5385 | 1998-02-21 03:14:50 +0000 | [diff] [blame] | 821 | Fixed a bug in e2fsck which could cause a core dump when it needs to | 
 | 822 | expand the /lost+found directory, and sometimes the bitmaps haven't | 
 | 823 | been merged in.  Also fixed a related bug where ext2fs_write_dir_block | 
 | 824 | was used to write out a non-directory block.  (Which would be bad on a | 
 | 825 | non-Intel platform with byte swapping going on.) | 
 | 826 |  | 
 | 827 | Fixed bug in e2fsck where it would print a "programming error" message | 
 | 828 | instead of correctly identifying where a bad block was in used when | 
 | 829 | the bad block was in a non-primary superblock or block group | 
 | 830 | descriptor.  Also fixed a related bug when sparse superblocks are in | 
 | 831 | use and there is a bad block where a superblock or block group | 
 | 832 | descriptor would have been in a group that doesn't include a | 
 | 833 | superblock. | 
 | 834 |  | 
 | 835 | Fixed a bug in e2fsck (really in libext2fs's dblist function) where if | 
 | 836 | the block group descriptor table is corrupt, it was possible to try to | 
 | 837 | allocate a huge array, fail, and then abort e2fsck. | 
 | 838 | ext2fs_get_num_dirs() now sanity checks the block group descriptor, | 
 | 839 | and subsitutes reasonable values if the descriptors are obviously bogus. | 
 | 840 |  | 
 | 841 | If e2fsck finds a device file which has the immutable flag set and the | 
 | 842 | i_blocks beyond the normal device number are non-zero, e2fsck will | 
 | 843 | offer to remove it, since it's probably caused by garbage in the inode | 
 | 844 | table. | 
 | 845 |  | 
 | 846 | When opening a filesystem, e2fsck specially checks for the EROFS error | 
 | 847 | code, and prints a specific error message to the user which is more | 
 | 848 | user friendly. | 
 | 849 |  | 
 | 850 | If the filesystem revision is too high, change the e2fsck to print | 
 | 851 | that this is either because e2fsck is out of date, or because the | 
 | 852 | superblock is corrupt.   | 
 | 853 |  | 
 | 854 | E2fsck now checks for directories that have duplicate '.' and '..' | 
 | 855 | entries, and fixes this corruption. | 
 | 856 |  | 
 | 857 | E2fsck no longer forces a sync of the filesystem (with attendant sleep | 
 | 858 | calls) at all times.  The ext2fs_flush() function now performs a sync | 
 | 859 | only if it needed to write data blocks to disk. | 
 | 860 |  | 
 | 861 | Fixed a minor bug in e2fsck's pass1b's file cloning function, where | 
 | 862 | certain errors would not be properly reported. | 
 | 863 |  | 
 | 864 | Updated and expanded a few points in the man pages which users | 
 | 865 | complained wheren't explicit enough. | 
 | 866 |  | 
 | 867 | Added special case byte-swapping code if compiling on the PowerPC, to | 
 | 868 | accomodate the strange big-endian variant of the ext2 filesystem that | 
 | 869 | was previously used on the PowerPC port. | 
 | 870 |  | 
 | 871 |  | 
 | 872 | Programmer's notes: | 
 | 873 | ------------------- | 
 | 874 |  | 
 | 875 | Removed C++ keywords from the ext2fs libraries so that it could be | 
 | 876 | compiled with C++. | 
 | 877 |  | 
 | 878 | E2fsck's internal organization has now been massively reorganized so | 
 | 879 | that pass*.c don't have any printf statements.  Instead, all problems | 
 | 880 | are reported through the fix_problem() abstraction interface.  E2fsck | 
 | 881 | has also been revamped so that it can be called as a library from a | 
 | 882 | application. | 
 | 883 |  | 
 | 884 | Added new fileio primitives in libext2fs for reading and writing | 
 | 885 | files on an unmounted ext2 filesystem.  This interface is now used by | 
 | 886 | debugfs. | 
 | 887 |  | 
 | 888 | Added a new libext2fs function for mapping logical block numbers of | 
 | 889 | a file to a physical block number. | 
 | 890 |  | 
 | 891 | Added a new libext2fs function, ext2fs_alloc_block(), which allocates | 
 | 892 | a block, zeros it, and updates the filesystem accounting records | 
 | 893 | appropriately. | 
 | 894 |  | 
 | 895 | Added a new libext2fs function, ext2fs_set_bitmap_padding(), which | 
 | 896 | sets the padding of the bitmap to be all one's.  Used by e2fsck pass 5. | 
 | 897 |  | 
 | 898 | The libext2fs functions now use a set of memory allocation wrapper | 
 | 899 | functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem, | 
 | 900 | instead of malloc, free, and resize.  This makes it easier for us to | 
 | 901 | be ported to strange environments where malloc, et. al. aren't | 
 | 902 | necessarily available. | 
 | 903 |  | 
 | 904 | Change the libext2fs fucntion to return ext2-specific error codes | 
 | 905 | (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using | 
 | 906 | and depending on the existence of system error codes (such as EEXIST | 
 | 907 | and ENOENT). | 
 | 908 |  | 
 | 909 | Renamed io.h to ext2_io.h to avoid collision with other OS's header | 
 | 910 | files. | 
 | 911 |  | 
 | 912 | Add protection against ext2_io.h and ext2fs.h being included multiple | 
 | 913 | times. | 
 | 914 |  | 
 | 915 | The types used for memory lengths, etc. have been made more portable. | 
 | 916 | In generla, the code has been made 16-bit safe.  Added Mark | 
 | 917 | Habersack's contributed DOS disk i/o routines. | 
 | 918 |  | 
 | 919 | Miscellaneous portability fixes, including not depending on char's | 
 | 920 | being signed. | 
 | 921 |  | 
 | 922 | The io_channel structure has a new element, app_data, which is | 
 | 923 | initialized by the ext2fs routines to contain a copy of the filesystem | 
 | 924 | handle. | 
 | 925 |  | 
 | 926 | ext2fs_check_directory()'s callback function may now return the error | 
 | 927 | EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to | 
 | 928 | really do the checking, despite the presence of the callback function. | 
 | 929 |  |

 | 932 | ============================== | 
 | 933 |  | 
 | 934 | Fixed e2fsck to detect (previously ignored) conflicts between the | 
 | 935 | superblock or block group descriptors and block bitmaps, inode | 
 | 936 | bitmaps, and inode tables. | 
 | 937 |  | 
 | 938 | Fixed bug in e2fsck so that when the message printed out when a block | 
 | 939 | or inode bitmap conflicts with other data, it has the correct group | 
 | 940 | number. | 
 | 941 |  | 
 | 942 | Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed | 
 | 943 | to badblocks.  This meant that not all of the filesystem was being | 
 | 944 | tested for bad blocks!  | 
 | 945 |  | 
 | 946 | Fixed an array boundary overrun case which cropped up in | 
 | 947 | ext2fs_badblocks_list_test when a user tried running "mke2fs -c  | 
 | 948 | -b 4096". | 
 | 949 |  | 
 | 950 | Adjusted the number of columns printed by mke2fs when displaying the | 
 | 951 | superblock backups to avoid running over 80 columns when making a | 
| Theodore Ts'o | 21d5385 | 1998-02-21 03:14:50 +0000 | [diff] [blame] | 952 | really big filesystem. | 
| Theodore Ts'o | bc21007 | 1997-06-17 05:41:36 +0000 | [diff] [blame] | 953 |  | 
 | 954 | Fixed up the man pages for e2fsck, debugfs, badblocks, chattr, | 
 | 955 | dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar | 
 | 956 | fixes), thanks to some suggestions from Bill Hawes (whawes@star.net). | 
 | 957 |  | 
 | 958 | Programmer's notes: | 
 | 959 | ------------------- | 
 | 960 |  | 
 | 961 | Fixed install rule in lib/ss so that ss_err.h is actually getting | 
 | 962 | installed. | 
 | 963 |  | 
 | 964 | Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting | 
 | 965 | bassed back to the caller. | 
 | 966 |  | 
 | 967 | Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been | 
 | 968 | setting the current inode number (which meant this function wasn't | 
 | 969 | working at all). | 
 | 970 |  | 
 | 971 | Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all | 
 | 972 | blocks in the bitmap when increasing the size of the bitmap. | 
 | 973 |  | 
 | 974 | Changed the initial number of blocks allocated by ext2fs_init_dblist() | 
 | 975 | to be more realistic. | 
 | 976 |  | 
 | 977 | Added a new function ext2fs_allocate_group_table, which sets up the | 
 | 978 | group descriptor information (and allocates inode and block bitmaps, | 
 | 979 | and inode tables for a particular group).  The function was created by | 
 | 980 | factoring out code form ext2fs_allocate_tables(). | 
 | 981 |  | 
 | 982 | Added a new function ext2fs_move_blocks which takes a bitmap of the | 
 | 983 | blocks to be moved, and moves them to another location on the | 
 | 984 | boardboard. | 
 | 985 |  | 
 | 986 | Make the unix_io channel's io_channel_flush implementation calls sync() | 
 | 987 | to to flush the kernel buffers to disk. | 
 | 988 |  | 
 | 989 | Added a new function ext2fs_dblist_count returns the number of | 
 | 990 | directory blocks in dblist. | 
 | 991 |  | 
 | 992 |  | 
| Theodore Ts'o | ae85148 | 1997-04-29 18:13:24 +0000 | [diff] [blame] | 993 | E2fsprogs 1.10 (April 24, 1997) | 
 | 994 | =============================== | 
 | 995 |  | 
 | 996 | Mke2fs once again defaults to creating revision #0 filesystems, since | 
 | 997 | people were complaining about breaking compatibility with 1.2 kernels. | 
 | 998 | Warning messages were added to the mke2fs and tune2fs man pages that | 
 | 999 | the sparse superblock option isn't supported by most kernels yet (1.2 | 
 | 1000 | and 2.0 both don't support parse superblocks.) | 
 | 1001 |  | 
 | 1002 | Added new flag to mke2fs, -R <raid options>, which allows the user to | 
 | 1003 | tell mke2fs about the RAID configuration of the filesystem.  Currently | 
 | 1004 | the only supported raid option is "stride" which specifies the width | 
 | 1005 | of the RAID stripe. | 
 | 1006 |  | 
 | 1007 | Fixed bug in e2fsck where pass1b would bomb out if there were any | 
 | 1008 | blocks marked bad in the inode table. | 
 | 1009 |  | 
 | 1010 | Fixed rare bug in mke2fs where if the user had a very unlucky number | 
 | 1011 | of blocks in a filesystem (probability less than .002) the resulting | 
 | 1012 | filesystem would be corrupt in the last block group. | 
 | 1013 |  | 
 | 1014 | Fixed bug where if e2fsck tried to allocate a block to fix a | 
 | 1015 | filesystem corruption problem and the filesystem had no free blocks, | 
 | 1016 | ext2fs_new_block() would loop forever. | 
 | 1017 |  | 
 | 1018 | The configure script now checks explicitly to see if "-static" works, | 
 | 1019 | since that can't be assumed to be true --- RedHat doesn't install | 
 | 1020 | libc-static by default. | 
 | 1021 |  | 
 | 1022 | Fixed bug in libext2's block iterator functions where under some | 
 | 1023 | cirmcustances, file with holes would cause the bcount parameter to the | 
 | 1024 | callback function to be incorrect.  This bug didn't affect any of | 
 | 1025 | e2fsprogs programs, but it was discovered by Paul Mackerras, the | 
 | 1026 | author of the PPC boot loader. | 
 | 1027 |  | 
 | 1028 | Removed use of static variables to store the inode cache in libext2fs. | 
 | 1029 | This caused problems if more than one filesystem was accessed via | 
 | 1030 | libext2fs (static variables in libraries are generally a bad idea). | 
 | 1031 | Again, this didn't affect e2fsprogs programs, but it was discovered by | 
 | 1032 | Paul Mackerras. | 
 | 1033 |  | 
 | 1034 | Fixed minor bugs and version code drift to assure that e2fsprogs 1.10 | 
 | 1035 | will compile cleanly with 1.2.13 kernels (even with a.out shared | 
 | 1036 | libraries!) | 
 | 1037 |  | 
 | 1038 | Programmer's notes: | 
 | 1039 | ------------------- | 
 | 1040 |  | 
 | 1041 | Added new functions to duplicate an ext2 filesystem handle, and its | 
 | 1042 | associated substructure.  New functions: ext2fs_dup_handle(), | 
 | 1043 | ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap(). | 
 | 1044 | Other structures, such as the io_channel and the inode_cache, now have | 
 | 1045 | a ref count so that they only get freed when they are no longer used | 
 | 1046 | by any filesystem handle.  (These functions were added as part of the | 
 | 1047 | development effort for an ext2 resizer). | 
 | 1048 |  | 
| Theodore Ts'o | 2ecc6fe | 1997-04-29 17:57:00 +0000 | [diff] [blame] | 1049 | E2fsprogs 1.09 (April 14, 1997) | 
 | 1050 | =============================== | 
 | 1051 |  | 
 | 1052 | Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was | 
 | 1053 | accidentally introduced in the 1.08 release.  The overhead calculation | 
 | 1054 | was accidentally removed, which caused ext2fs_initialize() to not | 
 | 1055 | notice when the filesystem size needed to be adjusted down because | 
 | 1056 | there wasn't enough space in the last block group. | 
 | 1057 |  | 
 | 1058 | Fixed bug in version parsing library routine; it was always parsing | 
 | 1059 | the library version string, instead of using the passed-in string. | 
 | 1060 |  | 
 | 1061 | Clarified chattr man page. | 
 | 1062 |  | 
| Theodore Ts'o | 24757fa | 1997-04-29 17:39:27 +0000 | [diff] [blame] | 1063 | E2fsprogs 1.08 (April 10, 1997) | 
 | 1064 | =============================== | 
 | 1065 |  | 
 | 1066 | E2fsck 1.07 was very slow when checking very large filesystems with a | 
 | 1067 | lot of files that had hard links (i.e., news spools).  This was fixed | 
 | 1068 | by seriously revamping the icount abstraction.  Added a formal test | 
 | 1069 | suite for the icount abstraction. | 
 | 1070 |  | 
 | 1071 | Debugfs now has a "-l" option to the "ls" command, which lists the | 
 | 1072 | inode number, permissions, owner, group, size, and name of the files | 
 | 1073 | in the directory. | 
 | 1074 |  | 
 | 1075 | Fix a bug in e2fsck where when a directory had its blocks moved to | 
 | 1076 | another location during the pass 1b processing, the directory block | 
 | 1077 | list wasn't updated, so pass 2 wouldn't check (and correct) the | 
 | 1078 | correct directory block. | 
 | 1079 |  | 
 | 1080 | E2fsck will now treat inodes which contain blocks which are claimed by | 
 | 1081 | the filesystem metadata by treating them as multiply claimed blocks. | 
 | 1082 | This way, the data in those blocks can be copied to a new block during | 
 | 1083 | the pass 1b--1d processing. | 
 | 1084 |  | 
 | 1085 | E2fsck will attempt to determine the correct superblock number and | 
 | 1086 | display it in the diagnostic and warning messages if possible. | 
 | 1087 |  | 
 | 1088 | Add support for a new (incompatible) feature, "sparse_super".  This | 
 | 1089 | feature reduces the number of blocks which contain copies of backup | 
 | 1090 | superblocks and block group descriptors.  (It is only an incompatible | 
 | 1091 | feature because of a bug in ext2_free_blocks.)  mke2fs and tune2fs now | 
 | 1092 | support a new -s option; e2fsck will recognize filesystems built with | 
 | 1093 | this feature turned on. | 
 | 1094 |  | 
 | 1095 | E2fsck now checks the library to make sure is the correct version, | 
 | 1096 | using new library functions.  (This helps to diagnose incorrectly | 
 | 1097 | installed e2fsprogs distributions.) | 
 | 1098 |  | 
 | 1099 | Dumpe2fs now prints more information; its now prints the the | 
 | 1100 | filesystem revision number, the filesystem sparse_super feature (if | 
 | 1101 | present), the block ranges for each block group, and the offset from | 
 | 1102 | the beginning of the block group. | 
 | 1103 |  | 
 | 1104 | Mke2fs now distributes the inode and block bitmap blok so that the | 
 | 1105 | won't be concentrated in one or two disks in RAID/striping setups. | 
 | 1106 | Also, if the user chooses a 2k or 4k block group, mke2fs will try to | 
 | 1107 | choose the largest blocks per group that be chosen.  (For 2k blocks, | 
 | 1108 | you can have up to 16384 blocks/group; for 4k blocks, you can have up | 
 | 1109 | to 32768 blocks/group.)  Previously mke2fs would not allow | 
 | 1110 | specification of more than 8192 blocks per group, even if you were | 
 | 1111 | using a 2k or 4k block group. | 
 | 1112 |  | 
 | 1113 | Programmer's notes: | 
 | 1114 | ------------------- | 
 | 1115 |  | 
 | 1116 | Added a new function ext2fs_create_icount2() which takes a "hint" | 
 | 1117 | argument.  This hint argument presets the icount array with the list | 
 | 1118 | of inodes which actually need to be in the icount array.  This really | 
 | 1119 | helps to speed up e2fsck. | 
 | 1120 |  | 
 | 1121 | Added a new function ext2fs_icount_validate() which checks the rep | 
 | 1122 | invariant for the icount structure.  This is used mostly for testing. | 
 | 1123 |  | 
 | 1124 | The error mesasage given when a bad inode number is passed to | 
 | 1125 | test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of | 
 | 1126 | EXT2FS_UNMARK_ERROR). | 
 | 1127 |  | 
 | 1128 | Added a new function ext2fs_set_dir_block which sets the block of a | 
 | 1129 | dblist entry, given the directory inode and blockcnt. | 
 | 1130 |  | 
 | 1131 | Added a new function ext2fs_get_library_version() which returns the | 
 | 1132 | current library version, and ext2fs_parse_version_string() which | 
 | 1133 | returns a version number based on a e2fsprogs version string. | 
 | 1134 |  | 
 | 1135 | The icount functions will return EINVAL if the passed in inode number | 
 | 1136 | is out of bounds. | 
 | 1137 |  | 
| Theodore Ts'o | 21c84b7 | 1997-04-29 16:15:03 +0000 | [diff] [blame] | 1138 | E2fsprogs 1.07 (March 9, 1997) | 
 | 1139 | ============================== | 
 | 1140 |  | 
 | 1141 | E2fsck is now uses much less memory when checking really large | 
 | 1142 | filesystems (or rather, filesystems with a large number of inodes). | 
 | 1143 | Previously a filesystem with 1 million inodes required 4 megabytes of | 
 | 1144 | memory to store inode count statistics; that storage requirement has | 
 | 1145 | now been reduced to roughly half a megabyte. | 
 | 1146 |  | 
 | 1147 | E2fsck can now properly deal with bad blocks appearing inside the | 
 | 1148 | inode table.  Instead of trying to relocate the inode table (which | 
 | 1149 | often failed because there wasn't enough space), the inodes in the bad | 
 | 1150 | block are marked as in use. | 
 | 1151 |  | 
 | 1152 | E2fsck will automatically try to use the backup superblocks if the | 
 | 1153 | primary superblocks have a bad magic number or have missing meta-data | 
 | 1154 | blocks (or meta-data blocks which are out of range). | 
 | 1155 |  | 
 | 1156 | E2fsck's pass 3 has been made more efficient; most noticeable on | 
 | 1157 | filesystems with a very large number of directories. | 
 | 1158 |  | 
 | 1159 | Completely revamped e2fsck's system of printing problem reports.  It | 
 | 1160 | is now table driven, to make them more easily customizeable and | 
 | 1161 | extendable.  Error messages which can be printed out during preen mode | 
 | 1162 | are now one line long. | 
 | 1163 |  | 
 | 1164 | Fixed e2fsck's filesystem swapping code so that it won't try to swap | 
 | 1165 | fast symbolic links or deleted files. | 
 | 1166 |  | 
 | 1167 | Fixed e2fsck core dumping when fixing a filesystem which has no | 
 | 1168 | directories (not even a root directory). | 
 | 1169 |  | 
 | 1170 | Added a check to e2fsck to make sure that the length of every | 
 | 1171 | directory entry is a multiple of 4 (since the kernel complains if it | 
 | 1172 | isn't). | 
 | 1173 |  | 
 | 1174 | Added a check to e2fsck to make sure that a directory entry isn't a | 
 | 1175 | link to the root directory, since that isn't allowed. | 
 | 1176 |  | 
 | 1177 | Added a check to e2fsk to now make sure the '.' and '..' directory | 
 | 1178 | entries are null terminated, since the 2.0 kernel requires it. | 
 | 1179 |  | 
 | 1180 | Added check to write_bitmaps() to make sure the superblock doesn't get | 
 | 1181 | trashed if the inode or block bitmap is marked as being block zero. | 
 | 1182 |  | 
 | 1183 | Added checking of the new feature set fields in the superblock, to | 
 | 1184 | avoid dealing with new filesystem features that this package wasn't | 
 | 1185 | set up to handle. | 
 | 1186 |  | 
 | 1187 | Fixed a fencepost error in ext2fs_new_block() which would occasionally | 
 | 1188 | try to allocate a block beyond the end of a filesystem. | 
 | 1189 |  | 
 | 1190 | When the UUID library picks a random IEEE 802 address (because it | 
 | 1191 | can't find one from a network card), it sets the multicast bit, to | 
 | 1192 | avoid conflicting with a legitimate IEEE 802 address. | 
 | 1193 |  | 
 | 1194 | Mke2fs now sets the root directory's owner to be the real uid of the | 
 | 1195 | user running mke2fs.  If the real uid is non-zero, it also sets | 
 | 1196 | the group ownership of the root directory to be the real group-id of | 
 | 1197 | the user running mke2fs. | 
 | 1198 |  | 
 | 1199 | Mke2fs now has more intelligent error checking when it is given a | 
 | 1200 | non-existent device. | 
 | 1201 |  | 
 | 1202 | When badblocks is given the -vv option, it now updates the block that | 
 | 1203 | it is currently testing on every block. | 
 | 1204 |  | 
 | 1205 | Fixed a bug in fsck where it wouldn't modify the PATH envirnoment | 
 | 1206 | currently correctly if PATH wasn't already set. | 
 | 1207 |  | 
 | 1208 | Shared libraries now built with dependencies.  This allows the shared | 
 | 1209 | library files to be used with dlopen(); it also makes the transition | 
 | 1210 | to libc 6 easier, since ld.so can tell which libc a particular shared | 
 | 1211 | library expects to use. | 
 | 1212 |  | 
 | 1213 | Programmer's notes: | 
 | 1214 | ------------------- | 
 | 1215 |  | 
 | 1216 | Added new abstraction (defined in dblist.c) for maintaining a list of | 
 | 1217 | blocks which belongs to directories.  This is used in e2fsck and other | 
 | 1218 | programs which need to iterate over all directories. | 
 | 1219 |  | 
 | 1220 | Added new functions which test to see if a contiguous range of blocks | 
 | 1221 | (or inodes) are available.  (ext2fs_*_bitmap_range). | 
 | 1222 |  | 
 | 1223 | Added new function (ext2_inode_has_valid_blocks) which returns true if | 
 | 1224 | an inode has valid blocks.  (moved from e2fsck code). | 
 | 1225 |  | 
 | 1226 | Added new function (ext2fs_allocate_tables) which allocates the | 
 | 1227 | meta-data blocks as part of initializing a filesystem.  (moved from | 
 | 1228 | mke2fs code). | 
 | 1229 |  | 
 | 1230 | Added a new I/O manager for testing purposes.  It will either allow a | 
 | 1231 | program to intercept I/O requests, or print debugging messages to | 
 | 1232 | trace the activity of a program using the I/O manager. | 
 | 1233 |  | 
 | 1234 | The badblocks_list functions now store the bad blocks in a sorted | 
 | 1235 | order, and use a binary search to speed up badblocks_list_test. | 
 | 1236 |  | 
 | 1237 | The inode scan function ext2fs_get_next_inode() may now return a soft | 
 | 1238 | error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in | 
 | 1239 | those cases where part of an inode table is missing or there is a bad | 
 | 1240 | block in the inode table.   | 
 | 1241 |  | 
 | 1242 | Added a new function (ext2fs_block_iterate2) which adds new arguments to | 
 | 1243 | the callback function to return a pointer (block and offset) to the | 
 | 1244 | reference of the block. | 
 | 1245 |  | 
 | 1246 | Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an | 
 | 1247 | application to jump to a particular block group while doing an inode | 
 | 1248 | scan. | 
 | 1249 |  | 
 | 1250 | The badblocks list functions were renamed from badblocks_* to | 
 | 1251 | ext2fs_badblocks_*.  Backwards compatibility functions are available | 
 | 1252 | for now, but programs should be modified to use the new interface. | 
 | 1253 |  | 
 | 1254 | Some of the library functions were reorganized into separate files to | 
 | 1255 | reduce the size of some programs which statically link against the | 
 | 1256 | ext2 library. | 
 | 1257 |  | 
 | 1258 | Put in some miscellaneous fixes for the Alpha platform. | 
 | 1259 |  |

 | 1261 | E2fsprogs 1.06 (October 7, 1996) | 
 | 1262 | ================================ | 
 | 1263 |  | 
 | 1264 | Fixed serious bug in e2fsck: if the block descriptors are bad, don't | 
 | 1265 | smash the backup copies in ext2fs_close().  (The problem was that when | 
 | 1266 | e2fsck -p discovered the problem, while it was closing the filesystem | 
 | 1267 | and exiting, it was also blowing away the backup superblocks on the | 
 | 1268 | disk, which was less than friendly.)  We now make it the case that we | 
 | 1269 | only write out the backup superblock and the back block descriptors if | 
 | 1270 | the filesystem is completely free from problems. | 
 | 1271 |  | 
 | 1272 | Fixed a bug in block_interate in the lib/ext2fs library which caused | 
 | 1273 | e2fsck to fail on GNU Hurd-created filesystems. | 
 | 1274 |  | 
 | 1275 | Add support for Linux/FT's bootloader, which actually uses | 
 | 1276 | EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want | 
 | 1277 | to clear the inode. | 
 | 1278 |  | 
 | 1279 | Add support for the "A" (no atime update) attribute.  (Note: this | 
 | 1280 | attribute is not yet in production kernels.) | 
 | 1281 |  | 
 | 1282 | The test suite is not automatically run when doing a "make all" from | 
 | 1283 | the top level directory.  Users should manually run "make check" if | 
 | 1284 | they wish to run the test suite. | 
 | 1285 |  | 
 | 1286 | Upon a preenhalt(), make the printed message more explicit that | 
 | 1287 | running e2fsck "MANAULLY" means without the -p or -a options. | 
 | 1288 |  | 
 | 1289 | In e2fsck, if a disconnected inode is zero-length, offer to clear it | 
 | 1290 | instead of offering to connect it to lost+found. | 
 | 1291 |  | 
 | 1292 | In e2fsck, if a filesystem was just unmounted uncleanly, and needs | 
 | 1293 | e2fsck to be run over it, change e2fsck to explicitly display this | 
 | 1294 | fact. | 
 | 1295 |  | 
 | 1296 | For dumpe2fs and e2fsck, cause the -V option to print out which | 
 | 1297 | version of the ext2fs library is actually getting used.  (This will | 
 | 1298 | help detect mismatches of using a 1.06 utility with a 1.05 library, | 
 | 1299 | etc.) | 
 | 1300 |  | 
 | 1301 | Programmers' notes: | 
 | 1302 | ------------------- | 
 | 1303 |  | 
 | 1304 | EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits | 
 | 1305 | the naming convention. | 
 | 1306 |  | 
 | 1307 | In ext2fs_initialize(), make sure the description for the inode bitmap | 
 | 1308 | is correctly initialize. | 
 | 1309 |  | 
 | 1310 | Fixed minor type typo in ext2fs_allocate_generic_bitmap(); | 
 | 1311 |  | 
| Theodore Ts'o | fc6d9d5 | 1997-04-29 14:51:31 +0000 | [diff] [blame] | 1312 | E2fsprogs 1.05 (September 7, 1996) | 
 | 1313 | ================================== | 
 | 1314 |  | 
 | 1315 | Add support for new fields in the ext2 superblock --- volume name, | 
 | 1316 | volume UUID, and last mounted field.  Dumpe2fs displays these fields, | 
 | 1317 | tune2fs and mke2fs allows you to set them.  E2fsck will automatically | 
 | 1318 | generate a UUID for those volumes that don't have them.   | 
 | 1319 |  | 
 | 1320 | Put in support for e2fsck to recognize HURD specific ext2 features --- | 
 | 1321 | most notably, the translator block.  The e2fsprogs tools will now use | 
 | 1322 | the creator_os field in the superblock to correctly handle different | 
 | 1323 | OS-specific variants of the ext2 filesystem. | 
 | 1324 |  | 
 | 1325 | E2fsck now fixes inodes which have a the deletion time set, but which | 
 | 1326 | have a non-zero i_link_count field by offering to clear the deletion | 
 | 1327 | time.  Previously e2fsck assumed that the inode was deleted (per 0.3c | 
 | 1328 | ext2 kernel behavior) and offered to unlink the file. | 
 | 1329 |  | 
 | 1330 | If e2fsck sets the clean bit, but nothing else, set the exit code | 
 | 1331 | FSCK_NONDESTRUCT.  After all, e2fsck did fix a filesystem error --- it | 
 | 1332 | set the filesystem valid bit when it was previously cleared.  :-) This | 
 | 1333 | was needed to make the HURD fsck driver happy. | 
 | 1334 |  | 
 | 1335 | If the  user  refuses to attach an  unattached  inode, e2fsck  will no | 
 | 1336 | longer set the inode's link count.  Otherwise, the  inode would end up | 
 | 1337 | getting marked as unused, which might cause loss of data later. | 
 | 1338 |  | 
 | 1339 | Make the message issued by e2fsck when the superblock is corrupt less | 
 | 1340 | confusing for users.  It now mentions that another reason for the | 
 | 1341 | "corrupt superblock" message might be that the partition might not be | 
 | 1342 | an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.) | 
 | 1343 |  | 
 | 1344 | Make the libext2 library more robuest so that e2fsck won't coredump on | 
 | 1345 | an illegal superblock where the blocksize is zero.  (f_crashdisk is | 
 | 1346 | the test case). | 
 | 1347 |  | 
 | 1348 | By default, create filesystems where the default checkinterval is 6 | 
 | 1349 | months (180 days).  Linux servers can be robust enough that 20 reboots | 
 | 1350 | can be a long, long time. | 
 | 1351 |  | 
 | 1352 | Added configure flag --enable-old-bitops, which forces the bitops to | 
 | 1353 | use the old (native) bitmask operations.  By default on the sparc | 
 | 1354 | platform, the standard ext2 bit ordering is now used. | 
 | 1355 |  | 
 | 1356 | Added a new feature to e2fsck to byte-swap filesystems; this can be | 
 | 1357 | used to convert old m68k filesystems to use the standard byte-order | 
 | 1358 | storage for the superblock, inodes, and directory blocks.  This | 
 | 1359 | function is invoked by using the '-s' option to e2fsck. | 
 | 1360 |  | 
 | 1361 | Debugfs's "dump" command has been enhanced so that it writes out the | 
 | 1362 | exact size of the file so that the nulls at the end of the file are | 
 | 1363 | eliminated.  The command also accept a new "-p" option which will | 
 | 1364 | attempt preserve to preserve the ownernship, permissions, and | 
 | 1365 | file modification/access times. | 
 | 1366 |  | 
 | 1367 | Debugfs has two new options, -f and -R.  The -R option allows the user | 
 | 1368 | to execute a single debugfs command from the command line.  The -f | 
 | 1369 | option allows the user to specify a "command file" containing debugfs | 
 | 1370 | commands which will get executed. | 
 | 1371 |  | 
 | 1372 | Dumpe2fs now pretty prints the check interval, instead of just | 
 | 1373 | printing the check interval as a number of seconds. | 
 | 1374 |  | 
 | 1375 | Fix bugs in debugfs: the params command when no filesystem is opened | 
 | 1376 | no longer causes a core dump.  It is now possible to unlink a file | 
 | 1377 | when a pathame containing a '/' is specified. | 
 | 1378 |  | 
 | 1379 | Tune2fs has a new -C option which sets the number of times the | 
 | 1380 | filesystem has been mounted. | 
 | 1381 |  | 
 | 1382 | Fix the chattr '-v' option so that it actually works.  Chattr was | 
 | 1383 | being buggy about the -v option parsing. | 
 | 1384 |  | 
 | 1385 | Programmers' notes: | 
 | 1386 | ------------------- | 
 | 1387 |  | 
 | 1388 | The directory lib/uuid contains a set of library routines to generate | 
 | 1389 | DCE compatible UUIDs.   | 
 | 1390 |  | 
 | 1391 | Extended ext2fs_namei() to handle symbolic links.  Added new function | 
 | 1392 | ext2fs_nami_follow() which will follow last symbolic link in the case | 
 | 1393 | where the pathname points to a sym link. | 
 | 1394 |  | 
 | 1395 | The ext2fs_block_iterate function will now return the HURD translator | 
 | 1396 | block, if present.  The new flag BLOCK_FLAG_DATA_ONLY will cause the | 
 | 1397 | iterator to return data blocks only.  The ext2fs.h file now defines | 
 | 1398 | constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and | 
 | 1399 | BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block | 
 | 1400 | count field of the iterator callback function. | 
 | 1401 |  | 
 | 1402 | The test script driver now takes an optional second argument, which is | 
 | 1403 | the test case to be run.  This allows you to run a test case without | 
 | 1404 | needing to run the entire test suite. | 
 | 1405 |  | 
 | 1406 | On Linux ELF systems, install the .so files in the correct places | 
 | 1407 | (/usr/lib).  The .so files must be stored in the same directory as the | 
 | 1408 | .a files. | 
 | 1409 |  | 
 | 1410 | Fixed miscellaneous HURD compilation issues with header file being | 
 | 1411 | included in the right order. | 
 | 1412 |  | 
 | 1413 | Fixed debugfs so that it resets optind to zero, not one, since setting | 
 | 1414 | optind to zero is more correct. | 
 | 1415 |  |

| Theodore Ts'o | a4d0961 | 1997-04-29 14:28:00 +0000 | [diff] [blame] | 1417 | E2fsprogs 1.04 (May 16, 1996) | 
 | 1418 | ============================= | 
 | 1419 |  | 
 | 1420 | First "official" (1.03 was a limited release only) to support building | 
 | 1421 | e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99 | 
 | 1422 | kernels). | 
 | 1423 |  | 
 | 1424 | This package includes a RPM specs file, that it can be built using the | 
 | 1425 | RedHat Package Manager. | 
 | 1426 |  | 
 | 1427 | E2fsck now prints a hint that if there are lots of incorrectly located | 
 | 1428 | inode bitmaps, block bitmaps, and inode table blocks, the user might | 
 | 1429 | want to try using e2fsck -b 8193 first, to see if that fares any | 
 | 1430 | better. | 
 | 1431 |  | 
 | 1432 | For ext2 filesystem written with the hurd, debugfs will now print out | 
 | 1433 | the translator field when printing an inode structure. | 
 | 1434 |  | 
 | 1435 | Lots of miscellaneous linking/installation cleanups: | 
 | 1436 |  | 
 | 1437 |   Libraries are now linked using a relative pathname, instead of | 
 | 1438 |   relying on -L working correct.  It doesn't, in many cases, including | 
 | 1439 |   current versions of GNU ld.  This guarantees that the build tree is | 
 | 1440 |   linking with the right libraries, instead of the ones installed in | 
 | 1441 |   /usr/lib. | 
 | 1442 |  | 
 | 1443 |   Header files, man pages, and the et/ss shell scripts are now | 
 | 1444 |   generated using a custom substitution script, instead of relying on | 
 | 1445 |   the configure script.  This prevents needless recompilation of | 
 | 1446 |   files; in addition, the custom substitution script is much faster. | 
 | 1447 |  | 
 | 1448 |   e2fsck may now be linked dynamically, by using the | 
 | 1449 |   --enable-dynamic-e2fsck flag to configure.  This is not recommended, | 
 | 1450 |   since it increases e2fsck's dependence on other files, but some | 
 | 1451 |   people need to save disk space, and other critical programs on their | 
 | 1452 |   systems were being linked dynamically anyway. | 
 | 1453 |  | 
 | 1454 |   Programs such as fsck which didn't need to be linked against | 
 | 1455 |   libext2fs (or mke2fs which didn't need to be linked against libe2p) | 
 | 1456 |   only link against libraries they actually need.  Otherwise, those | 
 | 1457 |   programs would require the presense of libraries that otherwise | 
 | 1458 |   could be removed from a rescuse diskette. | 
 | 1459 |  | 
 | 1460 |   The ss include files are now installed correctly so they can | 
 | 1461 |   actually be used by another package. | 
 | 1462 |  | 
 | 1463 |   If the profiling libraries are built, they are now installed on a | 
 | 1464 |   "make install-libs". |

 | 1468 | =============================== | 
 | 1469 |  | 
 | 1470 | Change the m68k bit numbering for bitmasks to match the bit numbering | 
 | 1471 | used by all other ext2 implementations.  (This change was requested by | 
 | 1472 | the m68k kernel development team.) | 
 | 1473 |  | 
 | 1474 | Support (in-development) filesystem format revision which supports | 
 | 1475 | (among other things) dynamically sized inodes. | 
 | 1476 |  | 
 | 1477 | Fixed a bug in the ext2 library so that an intelligent error is | 
 | 1478 | returned if mke2fs is run with a ridiculously small number of blocks | 
 | 1479 | for a partition. | 
 | 1480 |  | 
 | 1481 | Fixed a bug in the ext2 library which required that the device be | 
 | 1482 | openable in read/write mode in order to determine its size.  This | 
 | 1483 | caused e2fsck -n to require read/write access when it was not | 
 | 1484 | previously necessary. | 
 | 1485 |  | 
 | 1486 | Fixed a bug in e2fsck which casued it to occasionally fail the test | 
 | 1487 | suite depending on which version of the floating point library it was | 
 | 1488 | using. | 
 | 1489 |  | 
 | 1490 | Fixed a bug in e2fsck so that it now halts with a fatal error when | 
 | 1491 | certain superblock consistency checks fail.  Previously it continued | 
 | 1492 | running e2fsck, with some potential confusing/damaging consequences. | 
 | 1493 |  | 
 | 1494 | Added new flag to fsck which allows the root to be checked in parallel | 
 | 1495 | with other filesytems.  This is not the safest thing in the world to | 
 | 1496 | do, but some system administrators really wanted it. |

 | 1501 | E2fsprogs 1.02 (January 16, 1996) | 
 | 1502 | ================================= | 
 | 1503 |  | 
 | 1504 | Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels. | 
 | 1505 |  | 
 | 1506 | Change e2fsck to print statistics of how many non-contiguous files are | 
 | 1507 | on the system.  Note that a file which is larger than 8k blocks, it is | 
 | 1508 | guaranteed to be non-contiguous. | 
 | 1509 |  | 
 | 1510 | In mke2fs, print a warning message if a user tries to format a whole | 
 | 1511 | disk (/dev/hda versus /dev/hda1).  If a user really wants to format a | 
 | 1512 | whole disk, the -F (force) option forces mke2fs to format a whole disk | 
 | 1513 | as a filesytem. | 
 | 1514 |  | 
 | 1515 | Fix a bug in fsck where in some cases it might start checking | 
 | 1516 | partitions in the next pass before it finishes checking partitions in | 
 | 1517 | the current pass.  This still won't cause two partitions on the same | 
 | 1518 | disk will be checked, so it's rarely a problem in real life. | 
 | 1519 |  | 
 | 1520 | Patch lsattr so that it won't hang when checking a named pipe. | 
 | 1521 |  | 
 | 1522 | Minor compilation fixes: | 
 | 1523 | 	* Fix the order of libraries that were linked in debugfs. | 
 | 1524 | 	* Allow the sources to be compiled with -ansi turned on. |
