LU-8465 e2fsck: print thread log properly
When multi-thread fsck is enabled, logs printed from multiple
threads could overlap with each other. The overlap sometimes
makes the logs unreadable because log_out() is used multiple times
for a single line.
This patch adds leading [Thread XXX] to each logs if multi-thread
is enabed by -m option.
This patch also adds message to show the group ranges and inode
numbers for each thread, which is useful for debuging multi-thread
check.

e2fsck: track errors/badness found for each inode
The present e2fsck code checks the inode, per field basis. It
doesn't take into consideration to total sanity of the inode.
This may cause e2fsck turning a garbage inode into an apparently
sane inode ("It is a vessel of fertilizer, and none may abide
its strength.").
The following patch adds a heuristics to detect the degree of
badness of an inode. icount mechanism is used to keep track of
the badness of every inode. The badness is increased as various
fields in inode are found to be corrupt. Badness above a certain
threshold value results in deletion of the inode. The default
badness threshold value is 7, it can be specified to e2fsck
using "-E inode_badness_threshold=<value>"
This can avoid lengthy pass1b shared block processing, where a
corrupt chunk of the inode table has resulted in a bunch of
garbage inodes suddenly having shared blocks with a lot of good
inodes (or each other).
LU-11882 e2fsck: zero date is not inode badness
Lustre FS OST has some precreated objects which have zeroed
creation time. e2fsck adds badness points for such inodes.
If OST has many precreated objects, e2fsck spends too much time
during phase2, because processes each of such inode.
Let's allow Lustre FS inode has zeroed time field for
precreated objects.

e2fsck: allow deleting or zeroing shared blocks
E2fsck fixes files that are found to be sharing blocks by cloning
the shared blocks and giving each file a private copy in pass 1D.
Allowing all files claiming the shared blocks to have copies can
inadvertantly bypass access restrictions. Deleting all the files,
zeroing the cloned blocks, or placing the files in the /lost+found
directory after cloning may be preferable in some secure environments.
The following patches implement config file and command line options
in e2fsck that allow pass 1D behavior to be tuned according to site
policy. It adds two extended options and config file counterparts.
On the command line:
-E clone=dup|zero
Select the block cloning method. "dup" is old behavior,
and is the default. "zero" is a new method that substitutes
zero-filled blocks for the shared blocks in all the files
that claim them.
-E shared=preserve|lost+found|delete
Select the disposition of files containing shared blocks.
"preserve" is the old behavior which remains the default.
"lost+found" causes files to be unlinked after cloning so
they will be reconnected to /lost+found in pass 3.
"delete" skips cloning entirely and simply deletes the files.
In the config file:

mke2fs: set overhead in super block
If overhead is not recorded in the super block, it is calculated
during mount in kernel, for bigalloc file systems it takes
O(groups**2) in time. For a 1PB device with 32K cluster size it takes
~12 mins to mount, with most of the time spent on figuring out
overhead.
While we can not improve the overhead algorithm in kernel due to the
nature of bigalloc, we can work out the overhead during mke2fs and set
it in the super block, avoiding calculating it every time when it
mounts.
Overhead is s_first_data_block plus internal journal blocks plus the
block and inode bitmaps, inode table, super block backups and group
descriptor blocks for every group. This patch introduces
ext2fs_count_used_clusters(), which calculates the clusters used in
the block bitmap for the given range.
When bad blocks are involved, it gets tricky because the blocks
counted as overhead and the bad blocks can end up in the same
allocation cluster. In this case we will unmark the bad blocks from
the block bitmap, convert to cluster bitmap and get the overhead, then
mark the bad blocks back in the cluster bitmap.
Reset the overhead to zero when resizing, we can not simply count the
used blocks as overhead like we do when mke2fs. The overhead can be
calculated by kernel side during mount.

AOSP: e2fsdroid: Don't skip unusable blocks in BaseFS.
Currently, basefs_allocator will iterate through blocks owned by an
inode until it finds a block that is free. This effectively ignores the
logical to physical block mapping, which can lead to a bigger delta in
the final image.
An example of how this can happen is if the BaseFS has a deduplicated
block (D), that is not deduplicated in the new image:
Old image: 1 2 3 D 4 5
New image: 1 2 3 ? 4 5
If the allocator sees that "D" is not usable, and skips to block "4",
we will have a non-ideal assignment.
Bad image: 1 2 3 4 5 ?
This patch refactors get_next_block() to acquire at most one block. It's
called a single time, and then only called in a loop if absolutely no
blocks can be acquired from anywhere else.
In a Virtual A/B simulation, this reduces the COW snapshot size by about
90MB.

AOSP: e2fsdroid: Fix logical block sequencing in BaseFS.
By iterating over blocks to write BaseFS, holes in the extent tree are
skipped. This is problematic because the purpose of BaseFS is to
preserve the logical to physical block assignment between builds. By not
preserving the location of holes, the assignment can be incorrect.
For example, consider the following block list for a file:
1 2 3 0 4 5
If this is recorded as:
1 2 3 4 5
If the first block changes to a hole, the intended mapping will not be
preserved at all:
0 1 2 0 3
This patch makes two changes to e2fsdroid to fix this. The first change
is that holes are now recorded in BaseFS, by iterating over the extent
tree rather than the block list, and inserting zeroes where appropriate.
The second change is that the block allocator now recognizes when blocks
have been skipped (either to deduplication or to holes), and skips the
same number of logical blocks in BaseFS as well.
In a Virtual A/B simulation, this reduces the COW snapshot size by
approximately 100MB.

When BaseFS specifies the same block for two files, it gets added to a
separate "dedup" bitmap, and removed from the free block bitmap. If the
new build does not use every block in this bitmap, there will be an
inconsistency: the block bitmap marks blocks as in-use when they are
actually free. Although this doesn't matter for AOSP's read-only file

necessary to check mntent if open(O_EXCL) succeeds because it means that
the device is not mounted.

lvcreate -L 1G -n lvol0 mygroup
mkfs.ext4 /dev/mygroup/lvol0 <<<--- This fails
It fails because it thinks that /dev/mygroup/lvol0 is mounted because
the device name in /proc/mounts is not updated following the lvrename.
Move the open(O_EXCL) check before the mntent check and return
immediatelly if the device is not busy.

e2fsck: avoid overflow with very large dirs
In alloc_size_dir() it multiples signed ints when allocating the
buffer for rehashing an htree-indexed directory. This will overflow
when the directory size is above 4GB, which is possible with largedir
directories having about 100M entries, assuming an average 3/4 leaf
fullness and 24-byte filenames, or fewer with longer filenames.
The same problem exisgs in get_next_block().
Similarly, the out_dir struct used a signed int for the number of
blocks in the directory, which may result in a negative size if the

Use appropriate unsigned variables for block counts, and use larger
types for calculating the byte count for memory offsets/sizes.
Such large directories not been seen yet, but are not too far away.

tst_libext2fs: Avoid multiple definition of global variables
gcc version 10 changed the default from -fcommon to -fno-common and as a
result e2fsprogs make check tests fail because tst_libext2fs.c end up
with a build error.
This is because it defines two global variables debug_prog_name and
extra_cmds that are already defined in debugfs/debugfs.c. With -fcommon
linker was able to resolve those into the same object, however with
-fno-common it's no longer able to do it and we end up with multiple
definition errors.
Fix the problem by using SKIP_GLOBDEFS macro to skip the variables
definition in debugfs.c. Note that debug_prog_name is also defined in
lib/ext2fs/extent.c when DEBUG macro is used, but this does not work even
with older gcc versions and is never used regardless so I am not going to
bother with it.

chattr.1: improve attribute formatting with labels and indented paragraphs
By convention, lists of options in man pages use a label followed by an
indented description, such as this example from the Options section:
-R Recursively change attributes of directories and
their contents.
But the Attributes section places the available attributes mid-sentence,
which makes it visually more difficult to parse:
A file with the 'a' attribute set can only be opened
in append mode for writing. [...]
When a file with the 'A' attribute set is accessed, its
atime record is not modified. [...]
This patch places a label beside each attribute description, which (in
my opinion) improves readability, especially when visually skimming the
list. For example:
a A file with the 'a' attribute set can only be
opened in append mode for writing.
A When a file with the 'A' attribute set is accessed,
its atime record is not modified.

libext2fs: fix potential OOB read check_for_inode_bad_blocks()
If the bad block list has been reset in the middle of an inode scan,
it's possible for bb->list[scan->bad_blocks_ptr] to result in an
out-of-bounds read access.
This is highly unlikely to happen under normal circumstances; in
particular, we generally don't use bad block inodes any more. In
addition, this would only happen if the bad block inode itself is
corrupt so e2fsck needs to wipe it out. This might cause e2fsck to
crash, but it will more likely cause a part of the inode table to be
wrongly considered invalid, causing file system to be incorrectly
fixed.
This was reported by TALOS as TALOS-2020-0974 and CVE-2020-6057, but
after closer examination, we don't believe this can be used in any way
to exploit the system or release information about the system, since
all this can do is to cause part of the inode table to be skipped when
it shouldn't be, and this can't be leveraged since any information
about the ASLR of the process is obsolete once e2fsck exits.

mmp: abstract out repeated 'sizeof(buf), buf' usage
The printf("%.*s") format requires both the buffer size and buffer
pointer to be specified for each use. Since this is repeatedly given
as "(int)sizeof(buf), (char *)buf" for mmp_nodename and mmp_bdevname
fields, with typecasts to avoid compiler warnings.
Add a helper macro EXT2_LEN_STR() to avoid repeated boilerplate code.
This can also be used for other superblock buffer fields that may not
have NUL-terminated strings (e.g. s_volume_name, s_last_mounted,
s_{first,last}_error_func, s_mount_opts) to simplify code and avoid
the need for temporary buffers for NUL-termination.
Annotate the superblock string fields that may not be NUL-terminated.

mmp: don't assume NUL termination for MMP strings
Don't assume that mmp_nodename and mmp_bdevname are NUL terminated,
since very long node/device names may completely fill the buffers.
Limit string printing to the maximum buffer size for safety, and
change the field definitions to __u8 to make it more clear that
they are not NUL-terminated strings, as is done with other strings
in the superblock that do not have NUL termination.

libext2fs: reserve the error code EXT2_ET_NO_GDESC
This is really only needed in the 1.46+ where the EXT2_FLAG_SUPER_ONLY
is honored by ext2fs_open to only read the superblock, so that
fs->group_desc can be NULL. We define it in the maint branch so that
we can be sure the error tables are kept in sync (in the unlikely case
that a new error code needs to be assigned in the maint branch).
