ChangeLog, jfs_compat.h, journal.c, pass3.c:

[tools/e2fsprogs.git] / e2fsck / ChangeLog

2000-08-22    <tytso@valinux.com>

        * super.c (release_orphan_inodes): Fix typo; should do bounds
                checking on next_ino instead of ino.

        * jfs_compat.h (J_ASSERT): 
        * journal.c (e2fsck_run_ext3_journal): 
        * pass3.c (adjust_inode_count): Use fatal_error() instead of exit().

        * unix.c: Use fatal_error() instead of exit() whenever possible.
                Also fix the fsck exit codes so that we use FSCK_USAGE
                when it is appropriate.  Rename global_signal_ctx to
                e2fsck_global_ctx and let it be exported globally.

        * util.c (fatal_error): Try to flush the I/O manager before
                forcing an exit.

2000-08-20    <tytso@valinux.com>

        * journal.c (e2fsck_journal_load): Fix **nasty** bug which caused
                e2fsck_check_ext3_journal to smash the journal because
                journal->j_transaction_sequence wasn't getting
                initialized.

        * journal.c: (recover_ext3_journal, e2fsck_run_ext3_journal): Move
                call to e2fsck_clear_recover from recover_ext3_journal to
                after the filesystem has been closed and reopened.
                Otherwise, the superblock in the filesystem handle will
                probably be stale, and will overwrite the newer version of
                the superblock written by the log recovery.

        * message.c (expand_inode_expression): Add support for %Iu and %Ig

        * problem.h (PR_0_CLEAR_ORPHAN_INODE): Add new problem code.

        * super.c (release_orphan_inodes, release_inode_block,
                release_inode_blocks): Update the block group descriptor
                counts when freeing the orphan inode.  Use
                PR_0_CLEAR_ORPHAN_INODE to report when we clear an orphan.

        * journal.c (e2fsck_run_ext3_journal): Fix a bug where we
                attempted to reopen the filesystem using the device name
                instead of the filesystem name.

2000-08-18    <tytso@valinux.com>

        * Makefile.in: Update the make dependencies
        
        * problem.c, problem.h: Add the problem codes: 
                PR_0_ORPHAN_ILLEGAL_BLOCK_NUM, 
                PR_0_ORPHAN_ALREADY_CLEARED_BLOCK, 
                PR_0_ORPHAN_ILLEGAL_HEAD_INODE, 
                PR_0_ORPHAN_ILLEGAL_INODE, PR_0_ORPHAN_INODE_INUSE

        * super.c (release_inode_blocks, release_orphan_inodes,
                check_super_block): Add support for clearing orphaned
                inodes from the unmounted filesystem.

        * journal.c (e2fsck_recover_ext3_journal): Remove the last orphan
                check; this is now handled in check_super_block ---
                non-journaled filesystems can use the orphan list in the
                future.  Also, move the the re-opening of the filesystem
                to e2fsck_run_ext3_journal().

2000-07-12  Andreas Dilger <adilger@turbolinux.com>

        * journal.c: implement loading of ext3 journal for recovery code

        * problem.c (fix_problem): return answer from PR_AFTER_CODE to caller.
                Add journal problems.

        * recovery.c (journal_recover): user-space ext3 journal recovery code

        * unix.c (main) : check journal and do recovery in separate steps

2000-08-07    <tytso@snap.thunk.org>

        * unix.c (calc_percent): Make sure that we don't take a floating
                exception if the max value is zero.  (should normally
                never happen, but...)

2000-07-13    <tytso@valinux.com>

        * Release of E2fsprogs 1.19

2000-07-06  Theodore Ts'o  <tytso@valinux.com>

        * unix.c (check_if_skip): Modify algorithm for checking
                s_max_mnt_count to match with the kernel.  (If
                s_max_mnt_count is negative, ignore the mnt_count check.)

        * unix.c (e2fsck_update_progress): Adjust the width of the
                progress bar dynamically, based on the filesystem name
                that we need to display.

        * unix.c (main): If the ext3 needs_recovery flag is set, call
                e2fsck_run_ext3_journal() and then restart the e2fsck run.

        * journal.c (e2fsck_run_ext3_journal): New file which contains
                logic to recover the ext3 journal.  This version relies on
                the kernel being able to mount the filesystem in order to
                run the journal.

2000-07-05  Theodore Ts'o  <tytso@valinux.com>

        * unix.c (e2fsck_update_progress): Only save and check the last
                percentage after multiplying it by 10, nor 1000, since we
                only need to save values to a tenth of a percent (and the
                percentage is already from 0 .. 100%, not 0 .. 1).
                Also, re-arrange the logic so that we do the time
                check only after doing the percentage check, and we
                only advance the spinner if we're about to display it.

2000-07-04  Theodore Ts'o  <tytso@valinux.com>

        * pass1.c (e2fsck_pass1): Check to see if the ext3 s_last_orphan
                field is set; if so, clear it, so that ext3 mounting code
                won't get confused by the fact that we've cleared out the
                orphaned inodes.

2000-06-10  Theodore Ts'o  <tytso@valinux.com>

        * pass5.c (check_block_bitmaps, check_inode_bitmaps): Add error
                checking for a "should never happen case".

        * problem.c, problem.h (PR_5_COPY_IBITMAP_ERROR,
                PR_5_COPY_BBITMAP_ERROR): Add new error codes.

2000-05-27  Theodore Ts'o  <tytso@valinux.com>

        * pass1.c (pass1, check_size): Apply patch from Chris Wedgewood
                (cw@foof.org) which checks to see if special devices have
                a non-zero size, and deals with it.

        * problem.c, problem.h (PR1_SET_NONZSIZE): Add new problem code.

2000-05-18  Theodore Ts'o  <tytso@valinux.com>

        * Makefile.in (install): Create a symbolic link for fsck.ext3 as
                well.

2000-05-08  Theodore Ts'o  <tytso@valinux.com>

        * problem.c, problem.h (PR_0_HURD_CLEAR_FILETYPE): Add new problem
                code. 

        * super.c (check_super_block): If the OS type in the superblock is
                the Hurd, check to see if the filetype feature is set, and
                offer to clear it if so.   This needs to be done since the
                Hurd doesn't properly support the filetype feature.
                (And since the hurd allows the transmogrification of files
                to special files and vice versa --- for no good reason
                that I can understand --- it can't support the filetype
                feature for the forseeable future, either.)

2000-04-03  Theodore Ts'o  <tytso@valinux.com>

        * unix.c: For platforms that don't define optarg.h, manually
                define optarg and optind.

2000-03-20  Theodore Ts'o  <tytso@valinux.com>

        * pass1.c (check_immutable, e2fsck_pass1_check_device_inode):
                Check for the append-only as well as the immutable flag.

        * problem.c (PR_1_SET_IMMUTABLE): Adjust message to include
                append-only flag.   Fix comment for compression flag.
        
2000-02-12    <tytso@snap.thunk.org>

        * unix.c (e2fsck_update_progress): Limit the number of updates to
                the progress bars to 8 times a second.  This allows a 9600
                baud console link to keep up.

2000-02-11    <tytso@snap.thunk.org>

        * unix.c (main): If compression is enabled on the filesystem,
                print a warning message (for now).

        * message.c: Add new compression shortcut: @c == compress

        * problem.c, problem.h (PR_1_COMPR_SET): Add new error code.

        * pass1.c (check_blocks): If the inode has EXT2_COMPRBLK_FL flag
                set, check to see if the filesystem supports compression.
                If it does pass this information down to process_block()
                so it can treat the compressed block flag words
                correctly.  If not, offer to clear the flag, since it
                shouldn't be set.  
                (process_block): If an inode has the compressed inode flag
                set, allow EXT2FS_COMPRESSED_BLKADDR.

        * pass1b.c (process_pass1b_block, delete_file_block,
                clone_file_block):
        * pass2.c (deallocate_inode_block): Use HOLE_BLKADDR to check to
                see if the block can be skipped.

2000-02-08    <tytso@snap.thunk.org>

        * util.c: Make resource tracking message more concise.

        * e2fsck.h:
        * pass1.c (mark_table_blocks, e2fsck_pass1): Remove
                ctx->block_illegal_map, since it's not needed by pass1,
                and pass1b has been modified to calculate it manually if
                needed.   This reduces the memory footprint needed by e2fsck.

        * pass1b.c (check_if_fs_block): New static function which returns
                whether or not a block overlaps with filesystem metadata.
                This replaces consulting the block_illegal_map bitmap.

        * Makefile.in: Call sync after finishing building all in this
                directory. 
        
        * unix.c (PRS): sync the filesystem before trying to use
                BLKFLSBUF, to minimize the chance of causing dirty blocks
                to get dropped.

        * e2fsck.h: Manually define BLKFLSBUF if not defined, and we're on
                a Linux/i386 system.
        
        * pass3.c (check_directory): Only do the loop detection algorithm
                if we've searched over 2048 parent directories and haven't
                found the end yet.  This means that in the common case, we
                don't allocate or clear the inode_loop_detection bitmap,
                which for large systems, merely clearing the bitmap for
                each directory was turning out to be quite expensive.
                Thanks to Jani Jaakkola (jjaakkol@cs.helsinki.fi) for
                identifying this problem.

2000-02-06  Theodore Ts'o  <tytso@valinux.com>

        * badblocks.c, e2fsck.h, ehandler.c, emptydir.c, extend.c,
                flushb.c, iscan.c, message.c, pass1.c, pass1b.c, pass3.c
                pass4.c, pass5.c, problem.c, scantest.c, swapfs.c, 
                unix.c, util.c: Add Internationalization support as 
                suggested by Marco d'Itri <md@linux.it>.

2000-02-02  Theodore Ts'o  <tytso@valinux.com>

        * e2fsck.h, flushb.c, scantest.c: Remove uneeded include of
                linux/fs.h 

2000-01-18  Theodore Ts'o  <tytso@valinux.com>

        * Makefile.in: Since LIBUUID can sometimes include "-lsocket"
                we need a separate DEPLIBUUID that can be used in
                Makefile's dependency rules.

1999-11-23    <tytso@valinux.com>

        * e2fsck.8.in: Update language about where to find a backup
                superblock.

1999-11-19    <tytso@valinux.com>

        * pass1.c (process_inodes): Add shortcut handling; if
                process_inodes_count is zero, return right away, to avoid
                calling qsort with a non-positive count.

        * message.c (safe_print): Fix to properly display ^A, ^B, etc. and
                to print Delete as ^?

        * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
                the source directory.

1999-11-10    <tytso@valinux.com>

        * Release of E2fsprogs 1.18

1999-11-10    <tytso@valinux.com>

        * problem.c (fix_problem): Support a new flag, PR_PREEN_NO which
                means the answer is assumed to be no in preen mode.  This
                is now used in the PR_1_SET_IMMUTABLE code, so that in
                preen mode we ignore these inodes and just print a warning
                message. 

1999-11-09    <tytso@valinux.com>

        * pass1.c (e2fsck_pass1): If the filesystem does not support
                imagic inodes, if an inode has the imagic flag set, offer
                to clear the imagic flag.  If a valid device/fifo/socket
                has the immutable flag set, call the new helper function
                check_immutable() to offerto clear the immutable flag.

        * pass2.c (check_filetype): Use the new ext2_file_type() helper
                function instead of calculating the file_type information
                manually.

        * pass3.c (e2fsck_reconnect_file): When adding a link to
                lost+found, calculate the filetype information so that
                ext2fs_link() can use the information if applicable.
                (get_lost_and_found): Create the /lost+found directory
                with the correct filetype information if applicable.

        * util.c (ext2_file_type), e2fsck.h: New function which returns
                the directory entry file type information given the
                inode's mode bits.

        * problem.c, problem.h: Added new problem codes PR_1_SET_IMAGIC
                and PR_1_SET_IMMUTABLE.

1999-11-07    <tytso@valinux.com>

        * pass4.c (e2fsck_pass4): Clear inode_imagic_map after freeing it,
                to prevent it from getting freed twice.

1999-11-06    <tytso@valinux.com>

        * unix.c (main): Close the filesystem before freeing the context,
                so that in the event of a free()-related segmentation
                violation, the filesystem is properly closed and written
                out.

1999-10-27    <tytso@valinux.com>

        * e2fsck.c (e2fsck_reset_context): When freeing
                ctx->inode_reg_map, we weren't zero'ing
                ctx->inode_reg_map, which could cause a segfault later on
                in the e2fsck run.

1999-10-26    <tytso@valinux.com>

        * problem.h (PR_2_SPLIT_DOT): Fix excess zero in problem code (now
                matches the standard convention).

1999-10-26    <tytso@valinux.com>

        * Release of E2fsprogs 1.17

1999-10-26    <tytso@valinux.com>

        * message.c (safe_print): Make safe_print take an char instead of
                an unsigned char to fix gcc warnings.

1999-10-25    <tytso@valinux.com>

        * util.c: For NT portability, don't redefine getchar(), since
                stdio defines that.  Instead we introduce a new
                abstract macro read_a_char() which is #defined to the
                right function as necessary.

        * problem.c, problem.h (PR_2_NULL_NAME): Add new problem code.

        * pass2.c (check_dir_block): Require that the length of the
                directory entry be at least 12 bytes.  Check to see if the
                filename is zero-length, and flag that as an error.

1999-10-22    <tytso@valinux.com>

        * Release of E2fsprogs 1.16

1999-10-22    <tytso@valinux.com>

        * pass2.c (check_filetype): If the filetype filesystem feature is
                not set, and a directory entry has a dirent feature, offer
                to clear it (since 2.0 kernels will do complain will
                interpret it as a very large name length field).

        * problem.c (PR_2_CLEAR_FILETYPE): Add new problem code.

1999-10-21    <tytso@valinux.com>

        * e2fsck.8.in: Update man page to use a more standard format (bold
                option flags and italicized variables), as suggested by
                Andreas Dilger (adilger@enel.ucalgary.ca)

        * pass4.c (e2fsck_pass4): If an inode is set in the
                inode_imagic_map bitmap, don't check to see if it is
                disconnected from the inode tree (because it almost
                certainly will be).  Free inode_imagic_map at the end of
                pass 4.

        * pass2.c (check_dir_block, check_filetype): If the FILETYPE
                feature is set, check the directory entry's filetype
                information field, and fix/set it if necessary.
                (e2fsck_pass2): Free the inode_reg_map bitmap at the end
                of pass 2.

        * pass1.c (e2fsck_pass1, alloc_imagic_map): Allocate and fill in
                information for inode_reg_map and inode_imagic_map, which
                indicates which inodes are regular files and AFS inodes,
                respectively.
                Since only the master superblock is written during a
                restart, force that superblock to be used after a restart;
                otherwise changes to the block group descriptors end up
                getting ignored.

        * problem.c, problemP.h: If e2fsck is run -n, make def_yn variable
                be 0 for "no".  Add support for a new flag, PR_NO_NOMSG,
                which supresses the problem message if e2fsck is run with
                the -n option.

        * problem.c, problem.h (PR_2_SET_FILETYPE, PR_2_BAD_FILETYPE): Add
                new problem codes.

        * message.c (expand_dirent_expression): Add support for %dt which
                prints the dirent type information.

        * e2fsck.c (e2fsck_reset_context): Free new bitmaps (inode_reg_map
                and inode_imagic_map).

        * e2fsck.h (e2fsck_t): Add new inode_reg_map and inode_magic_map
                to the context structure.

        * unix.c (PRS), util.c (ask_yn): Add #ifdef's to make
                e2fsprogs easier to port to non-Unix platforms.

1999-09-07    <tytso@valinux.com>

        * pass3.c (adjust_inode_count): Fix bug where we didn't keep the
                internal and external inode counts in sync when we
                decremented an inode whose link count was already zero.
                Now we skip incrementing or decrementing both link counts
                if we would cause an overflow condition.
                (expand_dir, expand_dir_proc): Change where we update the
                inode block count and size files so that the block count
                field is updated correctly when we create an indirect block.

1999-08-05    <tytso@valinux.com>

        * super.c (check_super_block): Check to see whether the
                inodes_per_group value in the superblock is insanely too
                high.

1999-08-02    <tytso@valinux.com>

        * pass1b.c (clone_file_block): Don't clear the dup_map flag if
                the block also shares data with the fs metadata when
                the count drops to 1, since the block should still be
                cloned, as fs metadata isn't included in the count.

1999-07-18  Theodore Ts'o  <tytso@valinux.com>

        * Release of E2fsprogs 1.15

1999-07-19    <tytso@valinux.com>

        * unix.c (usage): Add minimalist emergency help to the usage
                message. 

1999-07-18    <tytso@valinux.com>

        * unix.c: Add support for calculating a progress bar if the -C0
                option is given.   The function e2fsck_clear_progbar()
                clears the progress bar and must be called before any
                message is issued.  SIGUSR1 will enable the progress bar,
                and SIGUSR2 will disable the progress bar.  This is used
                by fsck to handle parallel filesystem checks.  Also, set
                the device_name from the filesystem label if it is
                available. 

        * e2fsck.h: Add new flags E2F_FLAG_PROG_BAR and
                E2F_FLAG_PROG_SUPRESS.  Add new field in the e2fsck
                structure which contains the last tenth of a percent
                printed for the user.

        * message.c (print_e2fsck_message): Add call to
                e2fsck_clear_progbar(). 

        * pass1.c (e2fsck_pass1):
        * pass2.c (e2fsck_pass2):
        * pass3.c (e2fsck_pass3):
        * pass4.c (e2fsck_pass4):
        * pass5.c (e2fsck_pass5): Add call to e2fsck_clear_progbar when
                printing the resource tracking information.

        * pass5.c (check_block_bitmaps, check_inode_bitmaps): If there is
                an error in the bitmaps, suppress printing the progress
                bar using the suppression flag for the remainder of the
                check, in order to clean up the display.

1999-06-30    <tytso@valinux.com>

        * unix.c (check_mount): Clean up the abort message displayed when
                the filesystem is mounted and either stdout or stdin isn't
                a tty.

1999-06-25    <tytso@valinux.com>

        * e2fsck.h:
        * pass1.c (pass1_get_blocks, pass1_read_inode, pass1_write_inode, 
                pass1_check_directory, e2fsck_use_inode_shortcuts): Make
                pass1_* be private static functions, and create new
                function e2fsck_use_inode_shortcuts which sets and clears
                the inode shortcut functions in the fs structure.

        * e2fsck.h:     
        * pass2.c (e2fsck_process_bad_inode): Make process_bad_inode() an
                exported function.

        * pass4.c (e2fsck_pass4): Call e2fsck_process_bad_inode to check
                if a disconnected inode has any problems before
                connecting it to /lost+found.  Bug and suggested fix by 
                Pavel Machek <pavel@bug.ucw.cz>

1999-06-21    <tytso@valinux.com>

        * unix.c (main): Add missing space in the disk write-protected
                message. 

1999-05-22    <tytso@rsts-11.mit.edu>

        * problem.c, problem.h (PR_0_INODE_COUNT_WRONG): Add new problem
                code. 
        
        * super.c (check_super_block): Add check to make sure the total
                number of inodes is sane, since this can be calculated
                from the number of groups times the number of inodes per
                group.   Offer to correct it if it is incorrect.

1999-03-19    <tytso@rsts-11.mit.edu>

        * pass5.c (check_block_end): Fix fencepost condition where when
                clearing the block padding we were missing the last position
                in the bitmap.

1999-05-17    <tytso@rsts-11.mit.edu>

        * unix.c (reserve_stdio_fds): Add safety check in case
                reserve_stdio_fds couldn't open /dev/null.

1999-03-14  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * util.c (print_resource_track): Use mallinfo if present to get
                more accurate malloc statistics.

        * pass3.c (get_lost_and_found): Check to see if lost+found is a
                plain file; if so, offer to unlink it.

        * problem.c, problem.h (PR_3_LPF_NOTDIR): Add new problem code.

1999-03-09  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * problem.c: Fix problem message for PR_1_BAD_GROUP_DESCRIPTORS so
                that the block group number is printed.  Add new prompt,
                PROMPT_UNLINK.

1999-01-09  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * Release of E2fsprogs 1.14

1999-01-09  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * message.c (safe_print): New function which prints strings,
                converting non-printable characters using the '^' and
                M-notation.  This function is now used to print directory
                name entries and pathnames.

Mon Jan  4 02:28:59 1999  Theodore Y. Ts'o  <tytso@mit.edu>

        * unix.c (main): Reset the context before calling ext2fs_close(),
                to avoid referencing already freed memory.

1998-12-15  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * Release of E2fsprogs 1.13

1998-12-03  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * Makefile.in: Updated dependencies.

1998-11-27  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * pass3.c (get_lost_and_found): If the filesystem is not opened
                read-only, then force /lost+found to be created if it is
                not present.

        * problem.c: Allow PR_3_NO_LF_DIR to be handled during a preen
                operation. 

1998-10-28  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * unix.c (main): Move ext2fs_close() after e2fsck_free_context()
                since e2fsck_free_context may reference data in ctx->fs.

        * e2fsck.c (e2fsck_reset_context): Make sure ctx->fs is non-NULL
                before checking ctx->fs->dblist.

1998-10-09  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * pass1.c (e2fsck_pass1): Use the device check subroutine on
                FIFO's and Socket's, so that we catch bogus immutable inodes.

        * pass2.c (process_bad_inode): Process bad socket and fifo's.

        * problem.h, problem.c: Define new problem codes PR_2_BAD_FIFO and
                PR_2_BAD_SOCKET.

1998-09-02  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * problem.c: Add PR_3_NO_DIRINFO error code.

        * super.c (check_super_value): Rename min and max to min_val and
                max_val to avoid possible cpp macro conflicts.

        * pass4.c (e2fsck_pass4): Rename max to maxgroup, to avoid
                possible cpp macro conflicts.
        
        * pass3.c (e2fsck_pass3): Rename max to maxdirs, to avoid possible
                cpp macro conflicts.
                (check_directory): Fix logic to avoid possible core dump
                in the case of ext2fs_get_dir_info returning NULL.  (By
                the time we get here, it should never happen, but...).
                Also simply/streamline the control flow of the function.

1998-08-17  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * unix.c (check_if_skip): Move the "not cleanly mounted" check
                ahead of the maximal mount and too long since checked tests.
                (reserve_stdio_fds): Make sure 0,1,2 file descriptors are
                open, so that we don't open the filesystem using the same
                file descriptor as stdout or stderr.

1998-08-01  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * pass2.c (e2fsck_pass2): Fix the progress accounting so that we
                get to 100%.

        * pass3.c (e2fsck_pass3): Change progress accounting to be
                consistent with the other e2fsck passes.                

        * e2fsck.c (e2fsck_run): At the end of each pass, call the
                progress function with the pass number set to zero. 

        * unix.c (e2fsck_update_progress): If the pass number is zero,
                ignore the call, since that indicates that we just want to
                deallocate any progress structures.

1998-07-09  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * Release of E2fsprogs 1.12

1998-07-09  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * unix.c (main): Fix typo in checking the incompat feature set; it
                should be checked against EXT2_LIB_FEATURE_INCOMPAT_SUPP.

1998-07-07  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * badblocks.c (test_disk): Don't clear the existing bad blocks
                list when using e2fsck -c, since it may cause blocks with
                marginal errors to be dropped from the bad blocks list.

Mon Jul  6 10:32:11 1998  Theodre Ts'o  <tytso@lurch.mit.edu>

        * pass1.c (e2fsck_pass1): Use ext2fs_sb structure for
                compatibility with older kernels.

1998-06-25  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * unix.c (e2fsck_update_progress): Remove unused variables.

1998-06-10  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * pass1.c, problem.h: Change blkcnt_t to be e2_blkcnt_t to avoid
                collision with LFS API.

        * pass1.c (e2fsck_pass1): Fix bug so that ext2_max_sizes is
                properly initialized.  
                (e2fsck_pass1): Don't allow the the boot loader inode to
                be a directory (clear the inode mode field if so).

1998-05-07  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * unix.c (PRS): Added new option -C, which causes e2fsck to print
                progress updates so that callers can keep track of the
                completion progress of e2fsck.  Designed for use by
                progress, except for -C 0, which prints a spinning report
                which may be useful for some users.

        * pass5.c (e2fsck_pass5): Use a finer-grained progress reporting
                scheme (useful for larger filesystems).

        * e2fsck.h: Add progress_fd and progress_pos, for use by the Unix
                progress reporting functions.

1998-04-28  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * pass1.c (process_inode_cmp): Use EXT2_QSORT_TYPE to define the
                appropriate return type for comparison functions for qsort.

        * e2fsck.h: Add #ifdef protection for unistd.h

        * super.c: Remove header files already included by e2fsck.h

1998-04-26  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * dirinfo.c (e2fsck_add_dir_info): Update function to pass the old
                  size of the memory to be resized to ext2fs_resize_mem().

1998-03-30  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * Makefile.in: Change to use new installation directory variables
                convention.  Fix uninstall rules to take $(DESTDIR) into
                account.  Remove cat8dir from the installdirs target,
                since modern man package don't necessarily put the cat
                directory in /usr/man/cat?.

1998-03-29  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * super.c, e2fsck.h: Always declare e2fsck_get_device_size() as an
                extern in e2fsck.h to prevent -Wall warnings.

        * pass4.c (e2fsck_pass4): Remove unused variable 'j'.

1998-03-28  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * super.c (check_super_block): Fix broken superblock sanity check
                when calculating blocks_per_group if s_log_frag_size !=
                s_log_block_size.  Since we don't support fragments, this
                isn't a bug deal, but it's good to get it fixed.

1998-03-23  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * unix.c: Fix bug in check of feature set, to make sure we can
                really fix this filesystem.

        * problem.h: Make blkcount type to be of type blkcnt_t.  Make the
                num field be a 64 bit type.  Add the problem code
                PR_1_FEATURE_LARGE_FILES

        * problem.c: Add table entry for the problem code
                PR_1_FEATURE_LARGE_FILES.

        * pass1.c (e2fsck_pass1): A non-zero i_dir_acl field is only
                a problem for directory inodes.  (Since it is also
                i_size_high now.)   If there are no large_files, then
                clear the LARGE_FLAG feature flag.  If there are
                large_files, but the LARGE_FLAG feature flag is not set,
                complain and offer to fix it.
                (check_blocks): Add support to deal with non-directory
                inodes that have i_size_high set (i.e., large_files).
                Don't give an error if a directory has preallocated
                blocks, to support the DIR_PREALLOC feature.
                (process_block, process_bad_block): The blockcnt variable
                is a type of blkcnt_t, for conversion to the new
                block_iterate2.

        * pass2.c (process_bad_inode): A non-zero i_dir_acl field is only
                a problem for directory inodes.  (Since it is also
                i_size_high now.)

        * message.c (expand_inode_expression): Print a 64-bits of the
                inode size for non-directory inodes.  (Directory inodes
                can only use a 32-bit directory acl size, since
                i_size_high is shared with i_dir_acl.)  Add sanity check
                so that trying to print out the directory acl on a
                non-directory inode will print zero.
                (expand_percent_expression): %B and %N, which print 
                pctx->blkcount and pctx->num, can now be 64 bit
                variables.  Print them using the "%lld" format if
                EXT2_NO_64_TYPE is not defined.

        * e2fsck.h: Add the large_flagsfield to the e2fsck context.

        * e2fsck.c (e2fsck_reset_context): Clear the large_flags
                field.

Sun Mar  8 23:08:08 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * pass3.c (fix_dotdot_proc): 
        * pass2.c (check_dot, check_dotdot, check_name, check_dir_block): 
        * message.c (expand_dirent_expression): Mask off the high eight
                bits of the directory entry's name_len field, so that it
                can be used for other purposes.

Fri Feb 27 00:01:39 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * e2fsck.c (e2fsck_run): Since E2F_FLAG_SIGNAL_MASK doesn't
                include EXT2_FLAG_RESTART anymore, we need to adjust this
                routine so that it *does* return in the case of it seeing
                EXT2_FLAG_RESTART.

        * pass1.c (e2fsck_pass1): ext2_get_next_inode() may call the group
                done callback function, which may set context abort
                flags.  So we need to test the context abort flags after
                we call ext2_get_next_inode().
                (process_inodes): If we abort due out of process_inodes,
                do a clean exit by breaking out of the for loop instead of
                just returning.

        * e2fsck.h (E2F_FLAG_SIGNAL_MASK): EXT2_FLAG_RESTART shouldn't be
                considered a SIGNAL mask (i.e., requiring an immediate
                abort of processing to restart).  FLAG_RESTART just means
                that we want to restart once pass 1 is complete.

Tue Feb 24 15:19:40 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * Change the progress function to return an integer; if returns 1,
                then the progress function is expected to have set the
                e2fsck context flag signalling a user abort, and the
                caller should also initiate a user abort.

Tue Feb 17 19:03:44 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * pass5.c (check_block_bitmaps, check_inode_bitmaps): Don't call
                end_problem_latch() unless there was actually a problem
                latched.  Simplifies semantics of the latch processing.

Mon Feb 16 17:31:44 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * e2fsck.h: Add new field, priv_data to the e2fsck context
                structure.  It should be used by callers of the e2fsck
                functions only, and not by anything in e2fsck itself.

Mon Feb 7 17:31:04 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * super.c: Instead of call ext2fs_get_device_size(), define and call
                e2fsck_get_device_size().  (This function may be stubbed
                out in special versions of e2fsck.)

        * pass3.c, pass4.c: Remove extra calls to the progress function
                that weren't needed.

        * mke2fs.8.in: Update man page to note that the format of the bad
                block file is the same as the one generated by badblocks. 

Sun Feb  1 07:57:14 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * dirinfo.c, e2fsck.c: Don't include com_err.h; it isn't needed.

        * e2fsck.h: Include <time.h> since it is needed

        * super.c: If EXT2_SKIP_UUID is defined, then skip the UUID
                processing. 

Tue Jan 20 15:37:01 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * unix.c (main): In the case where the filesystem revision is too
                high, print the message about the superblock possibly
                being corrupt.

        * e2fsck.8.in: Add expanded comments about how the -b option
                works. 

Sat Jan 17 13:02:16 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * e2fsck.h: If EXT2_FLAT_INCLUDES is defined, then assume all of
                the ext2-specific header files are in a flat directory.

        * dirinfo.c, ehandler.c, pass1.c, pass1b.c, pass2.c, pass5.c,
                super.c, swapfs.c, unix.c: Explicitly cast all assignments
                from void * to be compatible with C++.

Tue Jan  6 11:30:24 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * unix.c (sync_disk): Remove sync_disk and calls to that function,
                since ext2fs_close() now takes care of this.

Mon Dec 29 14:45:42 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * pass1.c, pass1b.c, pass2.c, pass3.c, swapfs, badblocks.c,
                ehandler.c, unix.c: Change use of private to be priv_data,
                to avoid C++ reserved name clash.

Fri Nov 28 09:30:26 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * dirinfo.c (e2fsck_add_dir_info): Use ext2fs_get_num_dirs instead
                of e2fsck_get_num_dirs, which has been removed.

Tue Nov 25 15:54:35 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * Makefile.in (PROGS): Remove @EXTRA_PROGS@, since we don't want
                to compile and install flushb.

Mon Nov 24 06:48:00 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * pass1.c (e2fsck_pass1_check_device_inode): For now, only check
                to make sure the extra i_blocks in a device are cleared if
                the immutable flag is set.

        * util.c (print_resource_track): Fix typo which caused the
                time/resource tracking to print "Pass 1 :" instead of
                "Pass 1: ".

Thu Nov 20 16:02:23 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * pass3.c (expand_directory): Fix bug which could cause core dump
                when expanding the directory, and the bitmaps hadn't yet
                been read in.  Also, only use ext2fs_write_dir_block when
                writing a directory block, not when writing out a fresh
                indirect block.

Wed Nov 19 16:15:44 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * pass1.c (process_bad_block): Fix bug where first_block wasn't
                getting incremented, which caused user to get a
                "Programming error?" warning if there was a bad block in a
                non-primary superblock/group_descriptor.  Also fixed
                another bug so that ext2fs_bg_has_super() is consulted, to
                avoid problems when using a filesystem with the
                sparse_groups option set and there are bad blocks at the
                beginning of a group which doesn't have a superblock.

Thu Nov  6 16:10:20 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * pass1.c, pass2.c, pass3.c, pass4.c, pass5.c: Add calls to the 
                progress indicator function.

        * pass1.c (scan_callback): Add call to the progress feedback
                function (if it exists).

Tue Nov  4 09:45:36 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * super.c (check_super_block): Skip the device size check if the
                get_device_size returns EXT2_EXT_UNIMPLEMENTED.

        * iscan.c (main): Don't use fatal_error() anymore.

        * pass1b.c, swapfs.c, badblocks.c: Set E2F_FLAG_ABORT instead of
                calling fatal_error(0).

        * problem.c, pass3.c (PR_3_ROOT_NOT_DIR_ABORT, 
                PR_3_NO_ROOT_INODE_ABORT): New problem codes.
        
        * problem.c, pass2.c (PR_2_SPLIT_DOT): New problem code.

        * problem.c, pass1.c (PR_1_SUPPRESS_MESSAGES): New problem code.
        
        * problemP.h: New file which separates out the private fix_problem
                data structures.

        * util.c, dirinfo.c, pass1.c, pass1b.c, pass2.c, pass5.c, super.c,
                swapfs.c util.c: allocate_memory() now takes a e2fsck
                context as its first argument, and rename it to be
                e2fsck_allocate_memory().

Mon Nov  3 14:35:29 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * unix.c (main): Add a special case check for the error code EROFS
                and display an appropriate error message for this case.

        * [lots of files]:  Change ext2fs_read_inode, ext2fs_write_inode
                to take the e2fsck context as their first argument.
                Change dir_info.c routines to take an e2fsck_context,
                renamed them to start with e2fsck_ to avoid namespace
                issues, and changed them to store the directory
                information inside the e2fsck context.
                Added e2fsck_run() which calls all of the e2fsck passes in
                the correct order, and which handles the return of abort
                codes.  Added abort processing, both via setjmp/longjmp
                and via flags in the e2fsck context.  Use a flag in the
                e2fsck context instead of the restart_e2fsck global
                variable.   Change uses of free and malloc to
                ext2fs_free_mem and ext2fs_get_mem.
        
Fri Oct 31 01:12:43 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * pass1.c, pass3.c: Rename new error codes to _ET_ in them for
                consistency.

Sat Oct 25 00:10:58 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * pass3.c (get_lost_and_found): Check error return of 
                EXT2_FILE_NOT_FOUND instead of ENOTDIR

        * pass1.c (pass1_check_directory): Return EXT2_NO_DIRECTORY
                instead of ENOTDIR

Fri Oct 24 00:12:39 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * unix.c (PRS): Make the variable which getopt returns into be
                an int, so that it won't lose on platforms where char is
                unsigned. 

        * pass1b.c (clone_file): Fix bug in error reporting in the case
                where cs.errcode is non-zero.

Sun Oct 19 21:12:11 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * pass*.c, super.c, unix.c, util.c, e2fsck.h: Place #ifdef
                RESOURCE_TRACK around code which uses init_resource_track
                and print_resource_track.  (Not all systems have timeval)

        * super.c: Remove excess #includes which are not necessary.

        * e2fsck.h: Add #ifdef's for HAVE_SYS_TYPES_H and HAVE_SYS_TIME_H

Fri Oct  3 13:40:03 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * pass*.c, super.c: Massive changes to avoid using printf and
                com_err routines.   All diagnostic messages are now routed
                through the fix_problem interface.

Sat Sep  6 17:13:28 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

Tue Sep  2 09:04:51 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * problem.c: Added new problem codes for some of the
                superblock corruption checks, and for the pass header
                messages.  ("Pass 1: xxxxx")

        * util.c (print_resource_track): Now takes a description
                argument. 

Mon Aug 25 10:23:13 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * super.c, unix.c, e2fsck.c: New files to separate out the
                operating-specific operations out from e2fsck.c.  
                e2fsck.c now contains the global e2fsck context management
                routines, and super.c contains the "pass 0" initial
                validation of the superblock and global block group
                descriptors. 

        * pass1.c, pass2.c, pass3.c, pass4.c, pass5.c, util.c: Eliminate
                (nearly) all global variables and moved them to the e2fsck
                context structure.

        * problem.c, problem.h: Added new problem codes PR_0_SB_CORRUPT,
                PR_0_FS_SIZE_WRONG, PR_0_NO_FRAGMENTS,
                PR_0_BLOCKS_PER_GROUP, PR_0_FIRST_DATA_BLOCK

        * message.c: Add compression for the word "Illegal"

        * problem.c: Added entries for PR_2_BAD_CHAR_DEV and
                PR_2_BAD_BLOCK_DEV

Wed Aug 13 09:55:57 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * pass1.c (pass1, check_device_inode), pass2.c
                (process_bad_inode): Use a more stringent test for a valid
                device.

        * pass1.c (mark_table_blocks): Mark the superblock and group
                descriptor blocks first, so that any conflicts between
                these and the bitmap or inode table blocks is noticed.

        * problem.c: Fix message printed out when a block or inode bitmap
                conflicts with other fs data, has the correct group number
                in it.

Tue Jun 10 12:07:37 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * e2fsck.8.in: Fix minor typos and grammer oops found by Bill
                Hawes (whawes@star.net).

        * badblocks.c (read_bad_blocks_file): Pass the blocksize to the
                bad blocks command so that all of the filesystem gets
                tested in the case where the blocksize 2048 or 4096.

Thu Apr 24 12:16:42 1997  Theodre Ts'o  <tytso@localhost.mit.edu>

        * Release of E2fsprogs version 1.10

Mon Apr 21 22:43:08 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * 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.

        * Release of E2fsprogs version 1.08

Thu Apr 10 13:51:16 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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

        * e2fsck.h: Make block_illegal_map be a global variable

Sat Apr  5 11:51:58 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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.

Tue Mar 11 10:31:47 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * 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.

                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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * Release of E2fsprogs version 1.06

Mon Oct  7 00:45:30 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * Release of E2fsprogs version 1.05

Fri Aug 30 20:24:30 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * 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  <tytso@rsts-11.mit.edu>

        * e2fsck.c: Improve corrupt_msg, so that it's less confusing.

Thu May 16 11:12:30 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * Release of E2fsprogs version 1.04

Wed May 15 21:41:29 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>

        * 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    <tytso@rsts-11.mit.edu>

        * Release of E2fsprogs version 1.03

Tue Mar 26 12:03:42 1996    <tytso@rsts-11.mit.edu>

        * 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    <tytso@rsts-11.mit.edu>

        * 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    <tytso@rsts-11.mit.edu>

        * pass3.c (check_root): Fix spelling typo

Mon Feb  5 22:30:30 1996    <tytso@rsts-11.mit.edu>

        * 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    <tytso@rsts-11.mit.edu>

        * Release of E2fsprogs version 1.02

Wed Dec 15 21:24:26 1996    <tytso@rsts-11.mit.edu>

        * 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    <tytso@rsts-11.mit.edu>

        * 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    <tytso@rsts-11.mit.edu>

        * 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    <tytso@rsts-11.mit.edu>

        * 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    <tytso@rsts-11.mit.edu>

        * Makefile.in (install): Strip programs when they are installed.
                (e2fsck): Build e2fsck statically.

Wed Oct 25 21:18:16 1995    <tytso@rsts-11.mit.edu>

        * 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  <card@bbj>

        * ehandler.c:
          util.c: Include <sys/time.h> before <sys/resource.h>.  BSD needs it.

Mon Sep  4 10:14:49 1995    <tytso@rsts-11.mit.edu>

        * 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  <tytso@dcl>

        * util.c, ehandler.c: Move #include of <sys/resource.h> 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    <tytso@rsts-11.mit.edu>

        * 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    <tytso@rsts-11.mit.edu>

        * 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  <tytso@lurch.mit.edu>

        * 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  <tytso@lurch.mit.edu>

        * 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  <card@bbj>

        * 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  <card@bbj>

        * e2fsck.8: Updated date and version number.

Thu Aug 10 14:26:01 1995  Remy Card  <card@bbj>

        * 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  <tytso@dcl>

        * 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  <tytso@lurch.mit.edu>

        * 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  <tytso@lurch.mit.edu>

        * 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    <tytso@rsx-11.mit.edu>

        * 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    <tytso@rsx-11.mit.edu>

        * 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    <tytso@rsx-11.mit.edu>

        * 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    <tytso@rsx-11.mit.edu>

        * 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    <tytso@rsx-11.mit.edu>

        * 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 <linux/fs.h> if it doesn't exist.

        * scantest.c: Don't include <linux/fs.h>, <getopt.h>, or
                <mntent.h> if they don't exist.  (Mostly so that "make
                depend" works.)

        * pass1.c, pass1b.c, pass3.c, badblocks.c: Include <errno.h> (if
                it exists).

        * e2fsck.c, scantest.c: Don't include <getopt.h> if it doesn't
                exist. 

Mon Jun 12 08:37:49 1995  Theodore Y. Ts'o  <tytso@lurch.mit.edu>

        * 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  <tytso@lurch.mit.edu>

        * 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 <sys/stat.h>

        * 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 <errno.h>, since errno is
                used.

Thu Jun  8 12:31:19 1995  Miles Bader  <miles@churchy.gnu.ai.mit.edu>

        * 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 <linux/fs.h> 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  <card@bbj.ibp.fr>

        * pass1.c (pass1): Test the mode in reserved inodes (must be zero).

Sat Mar 11 13:12:16 1995  Theodore Y. Ts'o  <tytso@localhost>

        * 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    <tytso@rsx-11.mit.edu>

        * 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  <card@bbj>

        * 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.
