environment variables if the libraries are called from setuid or setguid
programs, or if kernel believes that the process is not eligible to create
a core dump. In addition, if the libc has __secure_getenv(), use it so that
the libc can also do any additional limitations regarding when libraries can
trust environment variables (i.e., to integrate with systems like SELinux
and Posix capabilities).

There are a number of bug fixes and enhancements over the original lustre fsck
BK repository. The biggest one is that this extended attribute values must
be aligned on 4-byte boundaries.
a new inode we make sure that the extra information in the inode (any extra
fields in a large inode and any ea-in-inode information) is cleared. This
can happen when e2fsck creates a new root inode or a new lost+found directory,
or when the user uses the debugfs write, mknod, or mkdir commands. Otherwise,
the newly create inode could inherit garbage (or old EA information) from
a previously deleted inode.

Also make sure that if a partition has a label removed, that the label is
removed form the blkid cache as well.
Add support for detecting 32k and 64k pagesize swap files.
unspecified, to avoid doing something surprising (such as unconditionally
deleting the first directory entry). Directory entries are now deleted
by coalescing them with the previous directory entry if possible, to
avoid directory fragmentation. This is not an issue with the e2fsprogs suite,
but may be a problem for some of the users of libext2fs, such as e2tools.
that mount will try to use the vfat filesystem. (Addresses Debian bug #287455)
Similarly, the blkid library will now return an ext3 type for ext 2/3
filesystems that have the journal capability set.
We allow files to be probed by the blkid library, to make it easier to
test the library. However, we also added safety checks to avoid saving
relative pathnames to blkid.tab, and probe_one() will only check block device
files.

reproduce problems that had been reported in the past, and which the
resize_inode changes tickled in a much more repeatable fashion.

ext2fs_create_resize_inode() will return a proper error code if the
resize inode is corrupt, instead of returning -1.
res_gdt.c (list_backups), closefs.c (ext2fs_bg_has_super),
ext2fs.h: Move ext2fs_list_backups() to res_gdt.c, and
ext2fs_bg_has_super() back to closefs.c. There's no
reason for the new file, since list_backups() isn't being
used by any other functions, and can be made static, and
all users of the ext2fs filesystem will have to call
ext2fs_close() anyway.

Update Makefile dependencies.
Update "make depend" production so that it filters out comments
inserted by newer gcc compilers.
Remove sync from e2fsck's "make all" target.
example, /tmp/test.img?offset=1024. Multiple options can separated using
the & character, although at the moment the only option implemented is
the offset option in the unix_io layer.
Change the maximum allowable blocksize to be 65536. This allows e2fsck to
check filesystems with a pagesize of 65536, and mke2fs to accept -b 65536.
Of course such a filesystem will not currently work on a Linux/x86 system,
at least not as of this writing!

the superblock and block group descriptors into two functions:
ext2fs_reserve_super_and_bgd, found in lib/ext2fs/alloc_sb.c, and
ext2fs_super_and_bgd_lock, found in lib/ext2fs/close.c.
Change e2fsck/pass1.c (mark_table_blocks), lib/ext2fs/closefs.c
(ext2fs_flush), lib/ext2fs/initialize.c (ext2fs_initialize),
and misc/dumpe2fs.c (list_desc) to use these functions.
e2fsck/ChangeLog
pass1.c (mark_table_blocks): Use the new function
ext2fs_reserve_super_and_bgd to calculate the blocks to be
reserved.
lib/ext2fs/ChangeLog
closefs.c (ext2fs_super_and_bgd_loc): New function which
centralizes the calculation of the superblock and block
group descriptors.
(ext2fs_flush): Use ext2fs_super_and_bgd_lock to figure
out where to write the superblock and block group
descriptors.
alloc_sb.c (ext2fs_reserve_super_and_bgd): New function which
reserves space in the block bitmap using
ext2fs_super_and_bgd_loc.
initialize.c (ext2fs_initialize): Use
ext2fs_reserve_super_and_bgd to initialize the block bitmap.
misc/ChangeLog
dumpe2fs.c (list_desc): Use ext2fs_super_and_bgd_loc to
determine the locations of the superblock and block group
descriptors.
superblock. E2fsck will automatically save the journal information
in the superblock if it is not there already, and will use it if the
journal inode appears to be corrupted. ext2fs_add_journal_inode()
will also save the backup information, so that new filesystems
created by mke2fs and filesystems that have journals added via
tune2fs will also have journal location written to the superblock as
well. Debugfs's logdump command has been enhanced so that it can
use the journal information in the superblock.
The debugfs man page has been improved to more fully describe the
logdump command.
Added two new functions, ext2fs_file_open2() and
ext2fs_inode_io_intern2() which take a pointer to an inode structure;
this is needed so that e2fsck and debugfs can synthesize a
fake journal inode and use it to access the journal.
error, then reflect that error upwards; don't try again
(forever). This prevents an infinite loop when /proc and
the /etc/blkid.tab file are not present.
non-empty bad block list. Resize2fs now discards any blocks on the
badblock list which are no longer part of the filesystem as the result
of a filesystem shrink. (Note: this means that shrinking and then
enlarging a filesystem is no longer a reversible operation;
information about bad blocks in the part of the filesystem
which is to be chopped off will be lost.)
device is larger than the default block size, then use the
sector size of the device as the default block size.
getsectsize.c (ext2fs_get_device_sectsize): New function which
returns the hardware sector size (if it is available).
Declare comerr-dev as replacing << e2fslibs-dev 1.33-2, to avoid
errors when upgrading to the new versions of comerr-dev and
e2fslibs-dev
Declare init_error_table as taking a long for the second argument.
Add support for OV-style continuation (closes Debian bug #191900).
Move /usr/include/com_err.h from the e2fslibs-dev package to the
comerr-dev package. (closes Debian bug #191899)
tune2fs to use the test I/O manager.
The test I/O manager has been changed to not do anything extra by
default, unless the TEST_IO_FLAGS and/or TEST_IO_BLOCK environment
variables are set, which controls what I/O operations are logged and
a block number to watch, respectively. The log messages are sent to
stderr by default, unless a filename is specified via the
TEST_IO_LOGFILE environment variable.

setting the pipe to non-blocking mode. Also fixed a file descriptor
leak. Made sure all functions call log entry/exit functions.
