Theodore Ts'o 6013915487 e2fsck: Add a global latch question for bad group descriptor checksums
Very often all the block group descriptors will have bad checksums, so
don't force the user answer 'yes' many, many times.

Theodore Ts'o fe26a55ac9 e2fsck: Fix and enhance superblock dates in future problem reports
Fixed a bug where e2fsck would report that last mount time was in the
future when it was really the last write time that was in the future.

Also, since people can't seem to believe that (a) their distribution
has buggy init scripts, or (b) their CMOS/RTC clock or backup battery
is dead, print the incorrect time and the current system time.

Theodore Ts'o 26ea4899d1 e2fsck: Fix superblock times in the future even if buggy_init_scripts=1
Unfortunately, distributions like Ubuntu seem to have buggy init
scripts that run e2fsck and mount the root filesystem before making
sure the system time and time zone is correctly set.  As a result, a
filesystem's last write and last mounted time can be set in future.
The buggy_init_scripts configuration option will stop e2fsck from
aborting the boot process, but it also inhibits the superblock times
from getting fixed.  This causes resize2fs to refuse to resize the
filesystem, even after running e2fsck on the file system.  To deal
with this, we need to fix the superblock write times unconditionally.

Theodore Ts'o b6bb99feb9 e2fsck: if i_file_acl_hi is non-zero, fix it and don't abort e2fsck -p
Ext3 filesystems don't care if i_file_acl_hi is non-zero in some
inode, and newer kernels should ignore this field (although 2.6.29 and
older kernels will not).  So e2fsck should fix this without aborting
an e2fsck preen operation.

Andreas Dilger 7494cbfd59 e2fsck: Add test code in problem.c to verify problem codes
We've hit a number of cases where the error codes in problem.h have
been assigned duplicate values compared to problems in our own e2fsck
patches, and this can lead to confusing and difficult to find bugs
in e2fsck (e.g. wrong problem messages, incorrect repair action, etc).

Attached is a test case for the problem.c file to ensure that the
problem table is sorted and does not contain any duplicate values.
Having the problem table sorted allows the correctness checking to be
very simple, and if it ever became important for performance we could
use binary searching of the problem table for the specific problem code.

The other problem codes associated with failing to create the

as well.  The two places which call e2fsck_get_lost_and_found()
already deal with a failure to create the directory, so there's no

Theodore Ts'o d45edec0fb e2fsck: Handle a pass 2 "should never happen" error gracefully
Turns out a "should never happen" error can indeed happen very easily
if a directory with an htree index has an incorrect, and too-large,
i_size field.  This patch fixes this so that we handle this situation
gracefully, allowing filesystems with this error to be fixed.

In another patch I will clean up the specific problem which caused the
internal "should never happen" error from happening at all, but patch
will prevent e2fsck from crashing, and prompt the user to remove the
htree index, so it can be rebuilt again after pass 3.

Thanks to Bas van Schaik at Tetra for giving me access to his system
so this problem could be debugged.

Theodore Ts'o f77704e416 Add directory hashed signed/unsigned hint to superblock
The e2fsprogs and kernel implementation of directory hash tree has a
bug which causes the implementation to be dependent on whether
characters are signed or unsigned.  Platforms such as the PowerPC,
Arm, and S/390 have signed characters by default, which means that
hash directories on those systems are incompatible with hash
directories on other systems, such as the x86.

To fix this we add a new flags field to the superblock, and define two
new bits in that field to indicate whether or not the directory should
be signed or unsigned.  If the bits are not set, e2fsck and fixed
kernels will set them to the signed/unsigned value of the currently
running platform, and then respect those bits when calculating the
directory hash.  This allows compatibility with current filesystems,
as well as allowing cross-architectural compatibility.
