The f_lotsbad regression test was failing on some systems with: Restarting e2fsck from the beginning... Pass 1: Checking inodes, blocks, and sizes +Illegal block number passed to ext2fs_test_block_bitmap #0 for in-use block map Pass 2: Checking directory structure Entry 'termcap' in / (2) has deleted/unused inode 12. Clear? yes Running with valgrind (./test_script --valgrind f_lotsbad) we see: +==31409== Conditional jump or move depends on uninitialised value(s) +==31409== at 0x42927A: ext2fs_test_generic_bmap (gen_bitmap64.c:378) among others. Looking at gen_bitmap64.c: 376: arg >>= bitmap->cluster_bits; 377: 378: if ((arg < bitmap->start) || (arg > bitmap->end)) { A little more debugging showed that it was actually bitmap->cluster_bits which was uninitialized, because it never gets copied over in ext2fs_copy_generic_bmap() Patch below resolves the issue.

This is the new version (1.41.14) 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.
