debugfs, e2fsck: fix s_desc_size handling
The s_desc_size in the superblock specifies the group descriptor
size in bytes, but in various places the EXT4_FEATURE_INCOMPAT_64BIT
flag implies that the descriptor size is EXT2_MIN_DESC_SIZE_64BIT
(64 bytes) instead of checking the actual size. In other places,
the s_desc_size field is used without checking for INCOMPAT_64BIT.
In the case of ext2fs_group_desc() the s_desc_size was being ignored,
and assumed to be sizeof(struct ext4_group_desc), which would result
in garbage for any but the first group descriptor. Similarly, in
ext2fs_group_desc_csum() and print_csum() they assumed that the
maximum group descriptor size was sizeof(struct ext4_group_desc).
Fix these functions to use the actual superblock s_desc_size if
INCOMPAT_64BIT.
Conversely, in ext2fs_swap_group_desc2() s_desc_size was used
without checking for INCOMPAT_64BIT being set.
The e2fsprogs behaviour is different than that of the kernel,
which always checks INCOMPAT_64BIT, and only uses s_desc_size to
determine the offset of group descriptors and what range of bytes
to checksum.
Allow specifying the s_desc_size field at mke2fs time with the
"-E desc_size=NNN" option. Allow a power-of-two s_desc_size
value up to s_blocksize if INCOMPAT_64BIT is specified. This
is not expected to be used by regular users at this time, so it
is not currently documented in the mke2fs usage or man page.
Add m_desc_size_128, f_desc_size_128, and f_desc_bad test cases to

It turns out that the s_desc_size validation in check_super_block()

verified earlier by ext2fs_check_desc(), and even without an

This is problematic if a caller instructs us to punch, say, blocks
12-15 of a 16-block cluster, because blocks 0-11 now point to a "free"
cluster.
The naive way to solve this problem is to see if any of the other
blocks in this logical cluster map to a physical cluster. If so, then
we know that the cluster is still in use and it mustn't be freed.
Otherwise, we are punching the last mapped block in this cluster, so
we can free the cluster.

clusters at the beginning and end of the punching range.

libext2fs: don't error out when punching a totally sparse file
If we're asked to punch a file with no data blocks mapped to it and a
non-zero length, we don't need to do any work in ext2fs_punch_extent()
and can return success. Unfortunately, the extent_get() function
returns "no current node" because it (correctly) failed to find any
extents, which is bubbled up to callers. Since no extents being found
is not an error in this corner case, fix up ext2fs_punch_extent() to
return 0 to callers.

libext2fs: fix punching extents when there are no left extents
When deleting an entire extent, we cannot always slip to the previous

libext2fs: don't overflow when punching indirect blocks with large blocks
On a FS with a rather large blockize (> 4K), the old block map
structure can construct a fat enough "tree" (or whatever we call that
lopsided thing) that (at least in theory) one could create mappings
for logical blocks higher than 32 bits. In practice this doesn't
happen, but the 'max' and 'iter' variables that the punch helpers use
will overflow because the BLOCK_SIZE_BITS shifts are too large to fit
a 32-bit variable. The current variable declarations also cause punch
to fail on TIND-mapped blocks even if the file is < 16T. So enlarge
the fields to fit.
Yes, this is an obscure corner case, but it seems a little silly if we
