TODO

User request:

BTW: Could you please add some sort of deleted and possibly corrupted file
     and inode list to e2fsck report. There should be filenames deleted
     from directory inodes, files with duplicate blocks e.t.c.
     It's pretty annoying to filter this information from e2fsck output
     by hand :-

------------------------------------------

Add a "answer Yes always to this class of question" response.

----------------------------------

ext2fs_flush() should return a different error message for primary
versus backup superblock flushing, so that mke2fs can print an
appropriate error message.

I'm reading the sorce code of e2fsck 1.14.
In pass2.c, lines 352-357, I read:

if ((dirent->name_len & 0xFF) > EXT2_NAME_LEN) {
        if (fix_problem(ctx, PR_2_FILENAME_LONG, &cd->pctx)) {
                dirent->name_len = EXT2_NAME_LEN;
                dir_modified++;
        }
}

I think that I'll never see any messages about too long filenames,
because "whatever & 0xFF" can never be "> 0xFF".
Am I wrong?
--------------------------------------

Add chmod command to debugfs.

------------------------------------------

fix up get_backup_sb, so that it doesn't choose something bogus if
fs->super->.... is ridiculous

----------------------------------

Maybe a bug in debugfs v.1.14:
if a file has more than one hardlink, only the first filename is shown when
using command
        ncheck <inode>

------------------------------------

Add a filesystem creation date to the superblock

Subject: DEBUGFS - thanks and a feature idea
Content-Type: TEXT/PLAIN; charset=US-ASCII

Theodore:

First, let me thank you for writing debugfs. Recently, my Linux box
(RH 6.0, 400 MHz PIII, on a DSL line) was hacked into.  The intruder did
an "rm -Rf" on a 34 GB drive with about 5GB of data on it.  I was able to
restore essentially the entire thing with debugfs and a bit of C code and Perl.
Actually, I could have done the entire thing with debugfs and Perl, but I
thought it would be too slow.

During this exercise, I noticed that one small feature was lacking that would
have made my job a bit easier.  The length of a deleted directory is
reported as 0, hence debugfs won't dump the contents of the directory to a
file using the "dump" command.  The only thing that saved me was that the
list of disk blocks is not zeroed out.  I was able to dump the contents of the
directories by using debugfs to get the relevant block numbers, then
using dd to get the actual data.

If debugfs had a feature where it ignored the size of a directory reported by
the inode and instead just dumped all the blocks, it would have facilited
things a bit. This seems like a very easy feature to add.

Again, thanks for writing debugfs (and all the other Linux stuff you've written!).

Cheers,

a) An option to mkfs to run badblocks in read/write mode.  The
filesystem is blank, so this is the perfect time to run the read/write
test.

b) An option to mkfs to zero the partition.  Yes, it can be done with
dd, but it would be a nicer way of doing it.
