Subject: [PATCH] ext2fs, 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.
Print out the s_desc_size field in debugfs "stats" and dumpe2fs
superblock output, if it is non-zero.
Add m_desc_size_128, f_desc_size_128, and f_desc_bad test cases to
verify mke2fs and e2fsck handling of larger group descriptor sizes.
e2fsck was not validating the s_desc_size in check_super_block().
Add a new LOG2_CHECK flag to check_super_value() to allow it to check
that s_desc_size is a power-of-two value, along with the MAX_CHECK
flag. This is also used to replace the open-coded power-of-two check
for s_inode_size.
It turns out that the s_desc_size validation in check_super_block()
is not currently used by e2fsck, because the group descriptors are
verified earlier by ext2fs_check_desc(), and even without an
explicit check of s_desc_size the group descriptors fail to alig
correctly on disk. It makes sense to keep the check_super_block()
regardless, in case the code changes at some point in the future.
