Thiemo Nagel 79a9ab1454 ext2fs_open2: Add more checks for filesystem consistency
Add more checks to assure the filesystem is sane to avoid later
division by zero errors.

Patch adds consistency checks on superblock to fix serveral crashes:
* require EXT2_INODES_PER_GROUP != 0
* require EXT2_DESC_PER_BLOCK != 0
* require s_first_data_block < s_blocks_count
* require group_desc_count * EXT2_INODES_PER_GROUP == s_inodes_count

README

	This is the new version (1.41.3) of the second extended file
system management programs.

	From time to time, I release new versions of e2fsprogs, to fix
bugs and to make the utilities more robust.  You can always find
information about the latest version at the the e2fsprogs web page,
which is:

	http://e2fsprogs.sourceforge.net

	The INSTALL file has instructions on building and installing
e2fsprogs.  Provisions for building Red Hat RPMs and Debian dpkg files
are supplied as well.

	In case of bugs in these programs, please contact Ted Ts'o at
tytso@mit.edu or tytso@alum.mit.edu.  See the e2fsck man page for
suggestions of what sort of information to include when submitting bug
reports for these programs.
