Thu Apr 24 12:16:42 1997 Theodre Ts'o * Release of E2fsprogs version 1.10 Mon Apr 21 22:43:08 1997 Theodore Ts'o * pass1b.c (pass1b): While scanning for inodes, simply skip inodes where ext2fs_get_next_inode returns the EXT2_ET_BAD_BLOCK_IN_INODE_TABLE error. Thu Apr 17 12:23:38 1997 Theodore Ts'o * Release of E2fsprogs version 1.09 Fri Apr 11 18:56:26 1997 Theodore Ts'o * Release of E2fsprogs version 1.08 Thu Apr 10 13:51:16 1997 Theodore Ts'o * pass1b.c (clone_file_block): If we clone a directory, we need to update the dblist entry so that we check (and correct) the right directory block. Sun Apr 6 09:13:12 1997 Theodore Ts'o * pass1.c (process_block): Don't clear blocks references to filesystem metadata; let pass 1B handle this case. * problem.c, problem.h: Add new problem, PR_1B_SHARE_METADATA. * pass1b.c (pass1d): Deal with a block which is shared with filesystem metadata. * e2fsck.h: Make block_illegal_map be a global variable Sat Apr 5 11:51:58 1997 Theodore Ts'o * e2fsck.c, pass1.c (mark_table_blocks): Support the sparse_super feature. (get_backup_sb): New function which attempts to obtain the correct backup superblock (if possible). Fri Apr 4 10:46:26 1997 Theodore Ts'o * e2fsck.c (main): Check the version of the library, and warn if the library is out of date; this happens generally due to users who manually install e2fsprogs. * pass1.c (pass1_get_blocks): If the passed in inode number for get_blocks isn't what we're expecting pass back EXT2_ET_CALLBACK_NOT_HANDLED. Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o * Release of E2fsprogs version 1.07 Tue Mar 11 10:31:47 1997 Theodore Ts'o * icount.c: New file which implements an inode count abstraction. This significantly reduces amount of memory needed to check really large filesystems. * pass1.c, pass2.c, pass3.c, pass4.c: Modified to use the icount abstraction. Fri Mar 7 08:28:55 1997 Theodore Ts'o * dirinfo.c (dir_info_iter): New function which allows iteration over the directories in the dir_info map. * pass3.c (pass3, check_directory): Speed up pass 3 by iterating over all directories in the dir_info structure, instead of iterating all inodes looking for directories, and then looking up the directories using get_dir_info(). Sat Feb 1 11:33:43 1997 Theodore Ts'o * pass1.c (pass1, process_block): * pass2.c (pass2): Use the ext2_dblist abstraction instead of manual code to manage the directory block list information. * pass1.c (check_blocks), pass1b.c (pass1b), pass2.c (deallocate_inode): Call the ext2 library routine ext2_inode_has_valid_blocks() instead of inode_has_valid_blocks(). * swapfs.c (swap_inodes): Add check so that we don't try to call swap_inode_blocks unless the inode has valid blocks. (Otherwise a long fast symlink might cause swap_inode_blocks to erroneously get called.) Wed Jan 22 14:42:53 1997 Theodore Ts'o * problem.c, problem.h: Added entries for PR_2_DOT_NULL_TERM and PR_2_DOT_DOT_NULL_TERM. * pass2.c (check_dot, check_dot_dot): Make sure the new . and .. entries are null-terminated, since the 2.0 kernel requires this (for no good reason). Mon Jan 20 20:05:11 1997 Theodore Ts'o * pass1.c (pass1): Set the EXT2_SF_SKIP_MISSING_ITABLE flag so that we can recover from missing inode tables. * dirinfo.c (get_dir_info): If there are no directories in the dir_info abstraction, don't core dump (because dir_info is NULL). * e2fsck.c (main): Don't try using the backup superblocks if there aren't any. (check_super_block): If there are illegal inode table or bitmaps, set the filesystem as being in error. Wed Jan 15 11:32:01 1997 Theodore Ts'o * pass2.c (check_dir_block): Added check to make sure that rec_len is a a multiple of 4 (so that the directory entries are 4-byte aligned). Sat Dec 28 12:16:32 1996 Theodore Ts'o * Makefile.in (uninstall): Uninstall all programs in the PROGS line. (PROGS): Don't build and install the extend program by default. Sat Dec 7 16:41:02 1996 Theodore Ts'o * pass1.c (process_inodes): Make sure the stashed_ino variable is saved and restored as well. (pass1): For fast sym links, skip the check_blocks processing step altogether. Mon Dec 2 09:28:24 1996 Theodore Ts'o * problem.c, message.c: New files, to completely refurbish how filesystem problems are reported to the user. The diagnostic messages are now encoded out in an easily customizable, extensible format. The messages printed out in preen mode are all on one line, and contain the device name. Fri Nov 29 20:26:08 1996 Theodore Ts'o * swapfs.c (swap_inodes): When swapping a filesystem, ignore deleted files. * pass1.c (pass1): Ignore missing inode table errors during the scan, and just skip past those inodes. * pass3.c (check_root): Remove root_ino argument, and assume that the root inode must be EXT2_ROOT_INO. Move responsibility of setting the parent of the root inode in the directory inode structure to pass2(). * pass2.c (check_dir_block): Don't allow links to the root directory. * dirinfo.c (add_dir_info): Remove last argument to add_dir_info, since the inode is no longer used. Tue Oct 15 00:06:49 1996 Theodore Ts'o * e2fsck.c (main): If the superblock magic number is wrong, or the block group fails a sanity check, then automatically restart trying to use the backup superblocks. * pass1.c (mark_table_blocks): Make the inode tables ahead of everything else; in the case where a bitmap block overlays the inode table, the inode table should take precedence. * pass2.c (maybe_clear_entry): Make the deleted/unused error message fit on one line, since the error can happen during a preen pass. (We eventually need to revamp the whole e2fsck error reporting and prompting system, but that's a job for another day.) Mon Oct 14 22:29:49 1996 Theodore Ts'o * e2fsck.c (main): Read in the list badblocks into fs->badblocks for the benefit of the inode scan functions. * pass1.c (pass1): If ext2fs_get_next_inode() returns an error indicating that an inode is in a bad block, mark that inode as being used, as well as in the inode "bb" map. * pass2.c (maybe_clear_entry): New function which generalizes the error cases when a directory entry needs to be cleared. (check_dir_block): If an inode is in the "bb" map, offer to clear the directory entry, since the inode is in a bad block. * pass4.c (pass4): If an inode is marked as used, but is is marked in the "bb" map, don't process it as a disconnected inode. Tue Oct 8 02:02:03 1996 Theodore Ts'o * Release of E2fsprogs version 1.06 Mon Oct 7 00:45:30 1996 Theodore Ts'o * e2fsck.c (main): Print out the version number of the shared library when using the -V option. * swapfs.c (swap_filesys): Change EXT2_SWAP to EXT2_FLAG_SWAP for consistency's sake. * e2fsck.c (main): By setting EXT2_FLAG_MASTER_SB_ONLY, only write out the backup superblocks when we know we have a valid filesystem. Tue Oct 1 22:00:29 1996 Theodore Ts'o * util.c (preenhalt): Make it explicit on preenhalt that running e2fsck manually means without the -a or -p flag. Fri Sep 27 14:41:08 1996 Theodore Ts'o * pass1.c (pass1): Add support for the EXT2_BOOT_LOADER inode. (Linux/FT actually sets the mode bits, so we have to handle it specially.) * e2fsck.c (check_if_skip): Print a message if the filesystem is just dirty, so that the user knows that it's about to be checked (since this will take a while). Mon Sep 16 17:00:01 1996 Theodore Ts'o * pass4.c: If a disconnected inode is zero-length, prompt to delete it instead of connecting it to lost+found. Thu Sep 12 15:23:07 1996 Theodore Ts'o * Release of E2fsprogs version 1.05 Fri Aug 30 20:24:30 1996 Theodore Ts'o * pass4.c (pass4): If the user refuses to connect an unattached inode to lost+found, don't try to set i_links_count. This is bad, since if the user says yes, the inode will be marked as unused, which is not necessarily the right thing, especially since the rest of the cleanup doesn't happen here. * pass2.c (deallocate_inode): Set inode_link_info[ino] when dellocating an inode. (Not strictly necessary, but...) * pass4.c (pass4): Add "bonehead" explanation to the "programming error" message. Tue Aug 27 11:26:32 1996 Theodore Ts'o * e2fsck.c (PRS,main): Added new options -s and -S. -s will byte-swap the filesystem so that it is normalized. -S will byte-swap the filesystem regardless of its current byte-order. * swapfs.c: New file, which will byte-swap a filesystem. Tue Aug 20 09:41:37 1996 Theodore Ts'o * pass1.c (pass1): Change handling on files with non-zero dtime and non-zero i_link_count; before we treated them as deleted file per botched ext2 0.3c kernel behavior. We now clear dtime instead. Mon Aug 19 23:33:57 1996 Theodore Ts'o * e2fsck.c (main): If e2fsck sets the clean bit, even if nothing else is changed, make sure FSCK_NONDESTRUCT is set (since after all having the filesystem set to invalid is an error. :-) Fri Aug 9 10:25:13 1996 Theodore Ts'o * pass1.c (process_block): Make sure that meta data doesn't get accidentally set in the dir_blocks array (which could happen in some error condtions). * pass1.c (pass1): * pass2.c (process_bad_inode): Check for fragments in a OS-independent fashion. Thu Aug 8 15:20:54 1996 Theodore Ts'o * e2fsck.c (check_if_skip): Close the filesystem when skipping the cleanup for the filesystem. Mon Jul 22 22:03:28 1996 Theodore Ts'o * e2fsck.c: Improve corrupt_msg, so that it's less confusing. Thu May 16 11:12:30 1996 Theodore Ts'o * Release of E2fsprogs version 1.04 Wed May 15 21:41:29 1996 Theodore Ts'o * e2fsck.c (relocate_hint): Issue a hint that the user may wish to try "e2fsck -b 8193" before allowing e2fsck to relocate inode table blocks. * Makefile.in (e2fsck): Build e2fsck statically or dynamically depending on the option to configure. Added targets for e2fsck.static and e2fsck.shared for people who want to build a static or shared variant manually. Wed Mar 27 00:33:40 1996 * Release of E2fsprogs version 1.03 Tue Mar 26 12:03:42 1996 * e2fsck.c (show_stats): Don't use floating point to display percentage of non-contiguous files, as different libc handle result truncation differently, and this causes the test suite to bomb out depending on which libc you are using. * util.c (allocate_memory): Fix error message to omit extraneous %%s. Tue Mar 5 03:50:40 1996 * pass4.c (pass4): * pass2.c (check_dir_block): * pass1.c (pass1): Add support for dynamic first inode revision. Wed Feb 14 16:27:30 1996 * pass3.c (check_root): Fix spelling typo Mon Feb 5 22:30:30 1996 * e2fsck.c (check_super_block): If the superblock fails certain internal consistency checks, exit with a fatal error after printing the "superblock is corrupt message". Wed Jan 31 11:06:08 1996 * Release of E2fsprogs version 1.02 Wed Dec 15 21:24:26 1996 * pass1.c (process_block): Check to see if a file is "fragmented". i.e., non-contiguous. Note that any file which is larger than the block group is guaranteed to be non-contiguous. We may want to use a different hueristic for deciding whether or not a file is "fragmented". * e2fsck.c (show_stats): Print statistics of how many non-contiguous files are on the system. Fri Dec 15 19:19:47 1995 * badblocks.c (read_bad_blocks_file, test_disk): Fold functionality of test_disk() (which runs badblocks) into read_bad_blocks_file(); test_disk() now calls read_bad_blocks_file() with a NULL bad_blocks_file argument. Mon Nov 20 18:30:10 1995 * e2fsck.c (check_mount): Use #if defined(__linux__) instead of #if defined(linux). The latter won't work if we're compiling -ansi. Mon Oct 30 20:31:17 1995 * e2fsck.c (check_mount): For Linux systems, the check to see if the root is mounted read-only has to be done for all filesystems, not just for the root filesystem, due to the way that some /etc/rc scripts are set up. Thu Oct 26 12:05:30 1995 * Makefile.in (install): Strip programs when they are installed. (e2fsck): Build e2fsck statically. Wed Oct 25 21:18:16 1995 * util.c (preenhalt): Preenhalt now takes an argument, which is an ext2fs_filsys; this allows it to set the EXT2_ERROR_FS flag in the superblock in cases where preenhalt is called. All calls to preenhalt() were changed to either preenhalt(fs) or preenhalt(NULL) in a few cases where the fs pointer was not available. (Most notable, for block read/write errors.) Mon Sep 4 21:41:03 1995 Remy Card * ehandler.c: util.c: Include before . BSD needs it. Mon Sep 4 10:14:49 1995 * e2fsck.c (show_stats): Show statistics about how many inodes have indirect, doubly indirect, and triply indirect blocks. Allow up to 8 digits for statistics, instead of merely 6, so things look pretty for large filesystems. * pass1.c (pass1): Keep statistics about indirect, doubly indirect, and triply indirect blocks. * pass1.c (unwind_pass1): Clear the above statistics when unwinding pass 1. Fri Aug 18 15:17:10 1995 Theodore Y. Ts'o * util.c, ehandler.c: Move #include of after #include of "e2fsck.h", since sys/resource.h may depend on sys/time.h, which is #included in e2fsck.h. Thu Aug 17 22:33:37 1995 * e2fsck.c (check_mount): Use the new ext2fs_check_if_mounted() function to determine if the device is mounted. * e2fsck.c (main): Add better error messages if ext2fs_open() fails. Wed Aug 16 16:25:02 1995 * pass1.c (check_blocks): If we're clearing a directory, clear pb.is_dir so we don't do the following check of making sure the directory size matches; this is pointless, since we've already cleared the inode. Fri Aug 11 09:08:54 1995 Theodore Y. Ts'o * pass1.c (bad_primary_block): New function, called by process_bad_block, which explains the facts of life to the user when a block in the primary superblock or primary group descriptors is bad. * pass2.c (check_dot): Handle the case where the first directory entry is used, but not ".". * pass2.c (check_dotdot): Handle the case where the second directory entry is used, but is not "..". Thu Aug 10 10:05:10 1995 Theodore Y. Ts'o * e2fsck.c (check_super_block): Get the size of the physical device and if it is smaller than the reported size of the filesystem, report an error. Sat Aug 12 03:39:18 1995 Remy Card * e2fsck.c (check_if_skip): Print the number of allocated files and blocks on clean filesystems. Fri Aug 11 14:15:36 1995 Remy Card * e2fsck.8: Updated date and version number. Thu Aug 10 14:26:01 1995 Remy Card * pass1.c (check_blocks): Check that directory size matches *exactly* the count of allocated blocks. Wed Aug 9 21:21:24 1995 Theodore Y. Ts'o * pass1b.c (pass1d): Free the shared[] array when we're done with it to avoid a memory leak. * pass1.c (unwind_pass1): Use ext2fs_free_block_bitmap to free the block_dup_map. * pass2.c (process_bad_inode): When clearing the inode, make sure the pathname is freed, to prevent a memory leak. * pass5.c (check_inode_bitmaps): Free free_array and dir_array when we're finished with them. (check_block_bitmaps): Free free_array when we're finished with them. * Makefile.in (e2fsck, flushb): Use $(LD) instead of $(CC) when linking the executable. * pass2.c (process_bad_inode): Even on OS's that don't support the fragment fields, make sure the Linux equivalent fields are set to zero. If an OS wants to reuse these fields, which is probably a bad idea (although we may get desperate in the future) this code will have to be changed. * pass1.c (dir_block_cmp): If the block numbers are equal, compare on the inode field, and then blockcnt field. This is just to keep the ordering of dir_blocks the same on all platforms when there are more than on missing directory blocks, which are indicated directories with holes, which are indicated with the block number being set to zero. Sun Aug 6 15:40:58 1995 Theodore Y. Ts'o * pass1.c (check_blocks, process_block): check_blocks() modified to call the ext2fs_block_iterate() with BLOCK_FLAG_HOLE if the inode is a directory. process_block() now checks to see if a directory has a "hole", or missing block. If so, this fact is recorded in the directory block list so that the problem can be resolved in pass #2. * pass2.c (allocate_dir_block): Added allocate_dir_block() to allocate new blocks for directories with "holes". Called out of check_dir_block if a block in the directory block list is zero. * pass3.c (get_lost_and_found): Move location of free(block) to prevent possible memory leak. Sat Aug 5 12:42:22 1995 Theodore Y. Ts'o * pass2.c (check_dir_block): Use a automatic, fixed-saize array instead of alloca() --- alloca is not portable! Check to make sure the filename is not longer than EXT2_NAME_LEN, and offer to fix it by truncating it, since it should never happen. * e2fsck.c (PRS): Use malloc() instead of alloca() --- alloca() is not portable!! In any case putenv() in some systems must take a static character array or malloc()'ed memory; passing memory allocated using alloca() to putenv() is not advisable. * pass2.c (check_dot, check_dotdot): Use malloc() instead of alloca() --- alloca() is not portable!!! Tue Jul 18 20:04:02 1995 * pass1b.c (pass1c): * pass3.c (check_root, get_lost_and_found): * pass2.c (check_dir_block): Use ext2fs_{read,write}_dir_block to read/write the directory block. Mon Jul 17 04:00:56 1995 * util.c (ask_yn): Apply patch supplied by Peter A. Zaitcev to make sure VMIN and VTIME are set correct. Fri Jul 14 19:26:29 1995 * pass1.c (mark_block_used): Change to be an inline function. Assume that the block validity checks are already done, and use the fast variant of the bitmap functions. Thu Jul 13 08:10:55 1995 * pass5.c (check_block_bitmaps, check_inode_bitmaps): Check the bounds of the bitmaps in advance, and then use the fast variant of e2fs_test_{block,inode}_bitmap. * pass1.c (mark_block_used): Use ext2_fast_mark_block_bitmap since the bounds checking has already been done earlier. Wed Jul 12 02:22:46 1995 * pass1.c (pass1): Allocate and free the block_illegal_map, which is used for shortcut processing in process_block. (mark_table_blocks): Initialize block_illegal_map with the filesystem blocks. (describe_illegal_block): New helper function that describes why a block is illegal. (process_block): Use block_illegal_map as a shortcut to determine whether a block is bad. Use describe_illegal_block to print out why the block is illegal. Mon Jun 12 19:11:06 1995 Theodore Y. Ts'o (tytso@dcl) * flushb.c: Don't include if it doesn't exist. * scantest.c: Don't include , , or if they don't exist. (Mostly so that "make depend" works.) * pass1.c, pass1b.c, pass3.c, badblocks.c: Include (if it exists). * e2fsck.c, scantest.c: Don't include if it doesn't exist. Mon Jun 12 08:37:49 1995 Theodore Y. Ts'o * pass2.c (process_bad_inode, check_for_zero_long, check_for_zero_char): Change long to u32, and char to u8. Sun Jun 11 15:05:57 1995 Theodore Y. Ts'o * util.c (inode_has_valid_blocks): * pass2.c (process_bad_inode): * pass1.c (pass1, check_blocks, pass1_check_directory): Use LINUX_S_IS* instead of S_IS*. * e2fsck.h: Don't #include * flushb.c (main): Add #ifdef BLKFLSBUF around ioctl. (Although this program is pretty much useless if BLKFLSBUF isn't supported.) * e2fsck.c, badblocks.c: Add #include , since errno is used. Thu Jun 8 12:31:19 1995 Miles Bader * pass2.c (check_dot, check_dotdot, check_dir_block): Use alloca to allocate space for file names instead of using fixed size buffers. (process_bad_inode): Only check inode frag fields if HAVE_EXT2_FRAGS is defined (by configure). * pass1.c (pass1): Only check the inode frag fields if HAVE_EXT2_FRAGS is defined (by configure). * e2fsck.c (check_mount): Only check for a mounted filesystem if HAVE_MNTENT_H is defined (by configure). (PRS): Use alloca to allocate the new path string, instead of having a fixed size buffer (which was the wrong size anyway). (PRS): Only support the -F (flush) option if the BLKFLSBUF ioctl is defined. * e2fsck.h: Only include if HAVE_LINUX_FS_H is defined (by configure). * Makefile.in: Rewritten to conform to GNU coding standards and support separate compilation directories. Thu Apr 6 15:04:36 1995 Remy Card * pass1.c (pass1): Test the mode in reserved inodes (must be zero). Sat Mar 11 13:12:16 1995 Theodore Y. Ts'o * pass1.c (unwind_pass1): Clear the file type statistics counter when pass 1 needs to be restarted from scratch. * pass1.c (handle_fs_bad_blocks): Fix bug where bitmap blocks were being reallocated to blocks in the next block group, instead of the current block grup. * pass1.c (pass1, check_blocks): Set inode_link_info[ino] whenever inode.i_links_count is set. Tue Feb 14 01:38:04 1995 Theodore Y. Ts'o (tytso@rt-11) * pass1.c (process_block): Add checks for if the block is trepassing on a superblock or group descriptor table. Sat Dec 31 00:52:11 1994 * main.c (corrupt_msg): Extend the message which is printed out when the superblock is corrupt, to include the suggestion of using the -b option to specify an alternate superblock. Thu Nov 24 09:29:58 1994 Theodore Y. Ts'o (tytso@rt-11) * badblocks.c (read_bad_blocks_file): If we are adding or replacing bad blocks in the bad blocks inode, sanity check the bad block inode first, and clear out any illegal blocks. * pass2.c (check_name): Don't bomb out if the attempt to get the pathname of the containing directory returns an error; the directory may be too badly damaged to expect that ext2fs_get_pathname will always succeed. Use "???" if the pathname can't be obtained (it's only for a printf to the user anyway). The name of the containing directory and the bad filename were incorrectly interchanged in the user message. Fixed. * pass2.c (check_name, check_dir_block): Use a common static string for the unknown pathname. Mon Nov 7 22:30:54 1994 Remy Card * Fixed lots of printf formats to make sure that block and inode numbers are printed as unsigned integers. Mon Oct 24 14:10:46 1994 (tytso@rsx-11) * pass5.c (check_block_end): Fix calculation of how the last block in the block bitmap should be calculated. Wed Sep 7 10:01:13 1994 (tytso@rsx-11) * pass1b.c (pass1_dupblocks): Fix declaration of dup_inode_map to be an ext2fs_inode_bitmap, and free it properly. * e2fsck.h * e2fsck.c (main): Folded in Remy Card's changes to add a revision level to the superblock. Wed Aug 17 22:00:20 1994 Remy Card (card@bbj) * e2fsck.c (usage): Fixed bogus usage message. Wed Aug 17 11:21:45 1994 Theodore Y. Ts'o (tytso@rt-11) * pass1.c (process_bad_block): Fixed bug so that blocks in the backup superblocks and group descriptors are handled gracefully.
