mke2fs: fix UI problem caused by fuzzy translations
When the original message was changed from "(y, n)" to "(y, N)", this
caused the translations to be marked as "fuzzy". For those
translations that use a different characters for yes and no --- for
example, German, which uses j and n for "ja" and "nein" --- not having
the translation can cause user confusion since the user will type 'y',
and it will be interpreted as "No", since mke2fs is expecting that the
user will type some other character, such as 'j' or 'J' for "Ja" in
the German locale.

In commit
68a1de3df3 (debugfs: pretty print encrypted filenames in the

copying dirent->name and 0-terminating it, dirent->name is used

However, instead of using the precision to limit the number of

characters are output until a 0 is read, which results in garbage

e2fsck: eliminate bad update link count attempt
Extended attribute inodes have a link count of 1 but they are not
attached to any directories. When an xattr inode with zero ea
references is found, the remedy is to reconnect it to lost+found dir.
Since reconnect operation increments the link count, it would normally
become 2 but to avoid that, check_ea_inode() sets the link count to
zero in anticipation of reconnect operation. And it does it even when
e2fsck is invoked with -n option which causes a fatal e2fsck failure
as can be demonstrated with the following test script:
mke2fs -b 4096 -I 256 -F -O extent,ea_inode /dev/sdb 1G
mount /dev/sdb /mnt/sdb
touch /mnt/sdb/x
setfattr -n user.ie1 -v $(python -c "print 'v'*5000") /mnt/sdb/x
umount /dev/sdb
debugfs -w -R 'rm x' /dev/sdb
e2fsck -f -n /dev/sdb
In this case, e2fsck fails with the following error:
e2fsck 1.43.5-WIP (17-Feb-2017)

libext2fs: add ea_inode support to set xattr
This patch is a major update to how we decide where to put extended
attributes. The main motivation is to enable creating values in
extended attribute inodes. While doing this, we want to implement a
behavior that is as close to kernel as possible.
Existing set ea code deviates from kernel behavior which makes it harder
to implement ea_inode feature:
- kernel only sorts ea entries in xattr block, e2fsprogs implementation
sorts all entries on every update.
- e2fsprogs implementation shuffled things on every update so the order
of updates does not matter. Kernel does not reshuffle things.
- e2fsprogs could evacuate entries from inode body to xattr block and
vice versa. This behavior does not exist in kernel.
Such differences could lead to inconsistent behavior between fuse2fs and
a kernel mount.
With ea_inode feature, we also need to decide whether to put a value
in an inode or keep it 'inline'. In kernel implementation this
depends on current placement of entries.
To close the behavioral gap, ext2fs_xattr_set() now takes over the
decision about where to place ea values. This also allows it to raise
errors early instead of delaying them to a separate
ext2fs_xattrs_write() call later.

Use i_size to determine whether a symlink is a fast symlink
Current way of determining whether a symlink is in fast symlink
format is to call ext2fs_inode_data_blocks2(). If number of data
blocks is zero and EXT4_INLINE_DATA_FL flag is not set, then symlink
data must be in inode->i_block.
This heuristic is becoming increasingly hard to maintain because
inode->i_blocks count can also be incremented for blocks used by
extended attributes. Before ea_inode feature, extra block could come
from xattr block, now more blocks can be added because of xattr
inodes.
To address the issue, add a ext2fs_is_fast_symlink() function that
gives a direct answer based on inode->i_size field. This is
equivalent to kernel's ext4_inode_is_fast_symlink() function.
This patch also fixes a few issues related to fast symlink handling:
- Both rdump_symlink() and follow_link() interpreted symlinks with
0 data blocks to always mean fast symlinks. This is incorrect
because symlinks that are stored as inline data also have
0 data blocks. Thus, they try to read everything from
inode->i_block and miss the symlink suffix in inode extra area.
- e2fsck_pass1_check_symlink() had code to handle inode with
EXT4_INLINE_DATA_FL flag twice. The first if block always returns
from the function so the second one is unreachable code.

The xattr inode stores the referring inode number in its i_mtime,

mke2fs: fix hugefile creation so the hugefile(s) are contiguous
Commit
4f868703f6f2: "libext2fs: use fallocate for creating journals
and hugefiles" introduced a regression for the mke2fs hugefile
feature. The problem is that the fallocate library function
intersperses the extent tree metadata blocks with the data blocks, and
this violates the hugefile guarantee that the created files should be
physically contiguous on disk.
Unfortuantely the m_hugefile regression test was flawed, and didn't
pick up the regression.
This commit fixes the regression test so that it detects the problem
before fixing mke2fs, and also fixes the mke2fs hugefile by reverting

libext2fs: correctly write up the backup superblocks in big endian systems
This bug has been around since we added support for metadata

bf9f3b6d5b ("e2fsck: exit

are not supposed to have the EXT2_VALID_FS or the NEEDS_RECOVERY bits
set, and earlier 1.43.x versions of e2fsprogs were byte swapping the
shadow superblock each time it was written, so that every other backup
superblock was incorrectly byte swapped.
Fortunately the primary backup superblock was correctly written
(modulo having the VALID_FS bit set when it should not have been set)
so for the most part no one noticed. And very few architectures use
big endian byte ordering these days. (Even IBM has seen the light
with the ppcle architecture. :-)

bf9f3b6d5b caused f_desc_size_bad and
f_resize_inode to fail on a big endian system, which allowed me to

libext2fs: correctly subtract xattr blocks on bigalloc filesystems
ext2fs_inode_data_blocks2() calculates an inode's data block count by
subtracting the external xattr block, if any, from the total blocks.
But on bigalloc filesystems, the xattr "block" is actually a whole
cluster, so ext2fs_inode_data_blocks2() would return a too-large value.
It seems this could have caused several different problems, but the one
I encountered was that xfstest generic/399 failed in the "bigalloc"
config because e2fsck incorrectly considered a symlink on the filesystem
to be corrupted at the end of the test. This happened because e2fsck
incorrectly calculated a nonzero data block count for a "fast" symlink
with an external xattr block and therefore treated it as a "slow"
symlink, which failed validation.
Fix this by updating ext2fs_inode_data_blocks2() to subtract the cluster
size rather than the block size.

e2fsck: fix multiply-claimed block quota accounting when deleting files
As e2fsck processes each file in pass1, the actual file system quota is
increased by the number of blocks discovered in the file. This can
include both non-multiply-claimed and multiply-claimed blocks, if the
latter exist. However, if a file containing multiply-claimed blocks
is then deleted in pass1b, those blocks are not taken into account when
decreasing the actual quota. In this case, the new quota values written
to the file system by e2fsck overstate the space actually consumed.
And, e2fsck must be run twice on the file system to fully correct
quota.
