libextr2fs: handle short reads/writes while creating the qcow file
This issue was flagged by Coverity, although its analysis was
incorrect. This isn't actually a memory overrun / security issue, but
rather a functional correctness issue since POSIX allows reads and
writes to be partially completed, and in those cases qcow2_copy_data()
could result in a corrutped qcow2 file.

In comparison with feeding a directory tree to mke2fs via -d this has
the following advantages:
- no superuser privileges, nor fakeroot, nor unshared user namespaces
are needed to create filesystems with arbitrary ownership information
and special files like device nodes which otherwise require being root
- by reading a tarball from standard input, no temporary files need to
be written out first as mke2fs can be used as part of a shell pipeline

resize2fs: avoid constantly flushing while moving blocks
resize2fs block_mover() flushes data after each extent and, curiously,
only if progress indicator is enabled, every inode_blocks_per_group

This significantly affects performance, e.g. on a tested large
filesystem on top of MD-RAID6+LVM+dm-crypt these flush calls reduce the
operation rate from approx. 500MB/s to 5MB/s, causing extremely long
shrinking times for large size deltas (70TB in my case).
Since this step performs just plain data copying and does not e.g. save
any progress/checkpoint information or similar metadata, it seems like
this flushing is of very limited usefulness, especially when considering

the case.
When mkfs is run to create a filesystem with following specifications:
* 1k blocksize and cluster-size greater than 32M
* 2k blocksize and cluster-size greater than 64M
* 4k blocksize and cluster-size greater than 128M
mkfs fails with "Invalid argument passed to ext2 library while trying

ratio is greater than 32k, mkfs fails with this error.
Went through the code and found out that the function
`ext2fs_new_range()` is the source of this error. This is because when
the cluster-size to blocksize ratio exceeds 32k, the length argument
to the function `ext2fs_new_range()` results in 0. Hence, the error.

mke2fs: do not set the BLOCK_UNINIT on groups has GDT
This patch prepares the expansion of GDT blocks beyond a
single group, by make mke2fs to not set BLOCK_UNINIT on
groups with GDT blocks, block/inode bitmaps, or inode table
blocks allocated.
Otherwise, we still rely on kernel side to initialize the
block bitmap if the groups has BLOCK_UNINIT set, and the
kernel doesn't know a group could have GDT blocks allocated,
so it would make an bad block bitmap.
As a result, expect output of several tests needs to be changed,
especially if the test uses dumpe2fs to print the group summary.

e2scrub: skip filesystems that don't have journals
Brian J. Murrell reported that e2scrub reports failures with one of his
filesystems. From the email discussion after he supplied a metadump:
AHA! This is an ext2 filesystem, since it doesn't have the
"has_journal" or "extents" features turned on:
# e2image -r /tmp/disk.qcow2 /dev/sda
# dumpe2fs /dev/sda -h

Filesystem UUID:
2c70368a-0d54-4805-8620-
fda19466d819
Filesystem magic number: 0xEF53
Filesystem revision #: 1 (dynamic)
Filesystem features: ext_attr resize_inode dir_index filetype sparse_super large_file
Filesystem flags: signed_directory_hash
Default mount options: user_xattr acl
Filesystem state: not clean with errors
(Note: Filesystem state == "clean" means that EXT2_VALID_FS is set in
the superblock s_state field; "not clean with errors" means that the
flag is not set.)
I bet the "journal only" preen doesn't actually reset the filesystem
state either:
# e2fsck -E journal_only -p /dev/sda
# dumpe2fs /dev/sda -h | grep state
dumpe2fs 1.47.1~WIP-2023-12-27 (27-Dec-2023)
Filesystem state: not clean with errors
Nope.
So now I know what happened -- when mounting an ext* filesystem that
doesn't have a journal, the driver clears EXT2_VALID_FS from the primary
superblock. This forces the system to run e2fsck after a crash, because
that's what you have to do for unjournalled filesystems.
The "e2fsck -E journal_only -p" call in e2scrub only replays the
journal. Since there is no journal, it exits almost immediately.
That's the intended behavior, but then it means that the "e2fsck -fy"
call immediately after sees that the superblock doesn't have
EXT2_VALID_FS set, sets it, and makes e2fsck return 1.
So that's why you're getting the e2scrub failures.
Contrast this to what you get when the filesystem has a journal:
# dumpe2fs -h /dev/sdb
dumpe2fs 1.47.0 (5-Feb-2023)
Filesystem volume name: <none>
Last mounted on: <not available>
Filesystem UUID:
e18b8b57-a75e-4316-87ce-

Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery sparse_super large_file
Filesystem flags: signed_directory_hash
Default mount options: user_xattr acl
Filesystem state: clean
Filesystems with journals retain their EXT4_VALID_FS state when they're
mounted.
Hmm. What e2scrub should do about unjournalled filesystems is a thorny
question. My initial thought is that it should skip them, because a
mounted unjournalled filesystem cannot by definition be kept consistent.
Therefore, teach e2scrub_all to avoid them and e2scrub to fail them at
the onset.
Restricting the scope of e2scrub sucks, but in the meantime at least it
means that your filesystem isn't massively corrupt. Thanks for the
metadump, it was very useful for root cause analysis.

e2scrub: fix pathname escaping across all service definitions
systemd services provide an "instance name" that can be associated with

However, systemd services aren't supposed to have slashes in them, so
we're supposed to escape them.
The canonical escaping scheme for pathnames is defined by the

a '-' in version.h::E2FSPROGS_VERSION (e.g. "1.46.6-rc1").
Otherwise, the '-' in the version can make RPM building unhappy.
Simplify the generation of E2FSPROGS_VERESION, E2FSPROGS_DATE and
E2FSPROGS_DAY to avoid multiple grep/awk/sed/tr stages.

libext2fs: don't truncate the orphan file inode if it is newly allocated
In ext2fs_create_orphan_file(), don't try truncating inode for the
orphan file if ext2fs_create_orphan_file() allocated the inode. This
avoids problems where the newly allocated inode in the inode table
might contain garbage; if the metadata checksum feature is enabled,
this will generally result in the function failing with a checksum
invalid error, but this can cause mke2fs (which calls
ext2fs_create_orphan_file) to fail.

e2fsprogs: modify dumpe2fs to report free block ranges for bigalloc
dumpe2fs has never been modified to correctly report block ranges
corresponding to free clusters in block allocation bitmaps from bigalloc
file systems. Rather than reporting block ranges covering all the
blocks in free clusters found in a block bitmap, it either reports just
the first block number in a cluster for a single free cluster, or a
range beginning with the first block number in the first cluster in a
series of free clusters, and ending with the first block number in the
last cluster in that series.
This behavior causes xfstest shared/298 to fail when run on a bigalloc
file system with a 1k block size. The test uses dumpe2fs to collect
a list of the blocks freed when files are deleted from a file system.
When the test deletes a file containing blocks located after the first
block in the last cluster in a series of clusters, dumpe2fs does not
report those blocks as free per the test's expectations.
Modify dumpe2fs to report full block ranges for free clusters. At the
same time, fix a small bug causing unnecessary !in_use() retests while
iterating over a block bitmap.

resize2fs: use Direct I/O when reading the superblock for online resizes
If the file system is mounted, the superblock can be changing while
resize2fs is trying to read the superblock, resulting in checksum

using Direct I/O, since the kernel makes sure that what gets written

e2fsck: fix handling of a invalid symlink in an inline_data directory
If there is an inline directory that contains a directory entry to an
invalid symlink, and that invalid symlink is the portion of the inline
directory stored in an xattr portion of the inode, this can result in
a buffer overrun.
When check_dir_block() is handling the in-xattr portion of the inline
directory, it sets the buf pointer to the beginning of that part of
the inline directory. This results in the scratch buffer passed to
e2fsck_process_bad_inode() to incorrect, resulting in a buffer overrun
if e2fsck_pass1_check_symlink() needs to read the symlink target (when
the symlink is too long to fit in the i_blocks[] space).
This commit fixes this by using the original cd->buf instead of buf,
since it can get modified when handling inline directories.

libsupport: fix function prototype for quota_write_inode()
Commit
2d2d799c7261 ("Clean up codes for adding new quota type")
changed the second paramter of quota_write_inode() from taking a
single quota type to taking a logical OR of (1 << quota_types).
The one thing this commit didn't change was the function prototype for
quota_write_inode() in the header file from an enum to an unsigned
int. Most C compilers don't seem to mind, and omission is mostly
harmless. However, mingw64 does issue a warning which gets promoted
to an error.
