e2fsck: fix quota accounting to use cluster units

2017-04-13T15:47:12+00:00

The quota accounting code in e2fsck's pass 1 and pass 3 uses block units
rather than cluster units when recording the allocated space consumed by
files and directories.  In pass 1, this causes a large undercount of
actual quota results and test failures for xfstests generic/383, /384,
/385, and /386 on bigalloc file systems.  In pass 3, this results in
quota accounting errors when the lost+found directory is either extended
or recreated on a bigalloc file system.

Use clusters rather than blocks when accounting for allocated space,
and correct a related header comment in the quota code.

Note that pass 1b also contains call sites for quota_data_sub() that
also need to be addressed.  However, it appears that more than just
unit conversion may be needed, so that will be left to a future patch.

e2fsck: fix project quota support

2016-05-22T02:18:16+00:00

Use a large_inode so that when e2fsck is fixing a file system with
project quota enabled, the correct project id's quota is adjusted when
a corrupted inode is deleted.

e2fsck: clean up feature test macros with predicate functions

2015-10-24T04:44:40+00:00

Create separate predicate functions to test/set/clear feature flags,
thereby replacing the wordy old macros.  Furthermore, clean out the
places where we open-coded feature tests.

e2fsck: check for an encrypted lost+found directory

2015-07-16T19:07:59+00:00

The /lost+found directory must not be encrypted, since e2fsck won't
have any keys.  If we find an encrypted lost+found directory, we
should delete the directory and recreate it.

e2fsck: don't complain about root dir csum failures when getting lnf

2014-12-14T02:55:22+00:00

Don't complain about checksum failures on the root dir when we're
trying to find l+f if the root dir is going to be rehashed anyway.

The test case for this is t_enable_mcsum in the next patch.

libext2fs/e2fsck: refactor everyone who writes zero blocks to disk

2014-10-13T08:31:17+00:00

Convert all call sites that write zero blocks to disk to use
ext2fs_zero_blocks2() since it can use Linux's zero out feature to do
the writes more quickly.  Reclaim the zero buffer at freefs time and
make the write-zeroes fallback use a larger buffer.

e2fsck: expand root dir if linking l+f fails

2014-09-11T22:09:14+00:00

If there isn't space in the root directory to add the lost+found
entry, try expanding the root directory before failing the fsck.
