tests: create random filesystem, corrupt, e2fsck
The f_random_corruption test enables a random subset of filesystem
features, picks one of the valid filesystem block and inode sizes,
and a random device size and creates a new filesystem with those
parameters.
It is possible to disable the running of the test by setting the
environment variable F_RANDOM_CORRUPTION=skip. By default the test
script is run only one time, but setting the LOOP_COUNT variable
allows the test to run multiple times.
If the script is running as root the filesystem is mounted and
populated with file data to allow a more useful test filesystem
to be generated. In some cases the kernel may not support the
requested filesystem features and the filesystem cannot be mounted.
This is not considered a test failure.
The resulting filesystem is corrupted with both random data and
by shifting data from one part of the device to another and then
repaired by e2fsck. In some rare cases the random corruption is
severe enough that the filesystem is not recoverable (e.g. small
filesystem with no backup superblock has bad superblock corruption)
but in most cases "e2fsck -fy" should be able to fix all errors
in some way.
After e2fsck has repaired the filesystem, it is optionally mounted
(if the environment variable MOUNT_AFTER_CORRUPTION=yes is set) and
the test files created in the filesystem are deleted. This verifies
that the fixes in the filesystem are sufficient for the kernel to
use the filesystem without error. Since there is some possibility
of the kernel oopsing if there is a filesystem bug, this part of
the test is not enabled by default.

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).

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.

mke2fs: recalculate the reserved blocks when the last BG is dropped
mke2fs -m option can set reserved blocks ratio up to 50%. But if the
last block group is not big enough to support the necessary data
structures, it gets dropped, we have to recalculate the number of
reserved blocks so that the reserved blocks matches the requested

It also avoids a problem where if the user specifies a reserved blocks

number of reserved blocks is greater than 50%, e2fsck will complain.
Steps to reproduce:
1. Create a FS which has the overhead for the last BG

Unfortunately, this was the wrong fix; $(ELF_OTHER_LIBS) *MUST* be

library and not include it into the DT_NEEDED section of the shared
library. The proper fix is to add a -L$(LIB) before $(LDFLAGS), and
then remove the -L option from all of the ELF_OTHER_LIBS definitions
in the library Makefiles.

The problem with this optimization is that we don't notice if the

the error indicator from the journal superblock to the file system
superblock, then the kernel will transfer it when the file system is
remounted read-write, causing scary messages to appear in the syslog.

Next e2fsck run then converts these into hidden quota inodes
(ino #3 & #4). But this approach has problems:
1) Before e2fsck run, the inodes are visible to the user and
might get corrupted or removed or replaced by the user.
2) Since these are user visible, we have to include
their block usage in the quota accounting. But once
these inodes are hidden, e2fsck will have to decrement
their usage from the quota accounting (which e2fsck
currently doesn't do and instead reports error).
(the following used to give e2fsck error previously:
# assume <dev> has aquota.user & aquota.group files
$ tune2fs -O quota <dev> # stores ino# of quota files in
# ext4 superblock
$ e2fsck -f <dev> # hides quota files, but now quota
# usage is incorrect.
<< quota errors >>
Instead of making e2fsck complicated, this patch creates the
hidden quota inodes at 'tune2fs -O quota' time iteself. The
usage is computed freshly and limits are copied from the
aquota.user and aquota.group files as earlier.

Fix blhc (Build Log Hardening Check) warnings
The Build Log Hardening Check is a debian tool which scans the output
of a package build making sure that the security hardening flags are
used when compiling and linking all of binaries in a package.
For the most part we were passing CFLAGS, CPPFLAGS, and LDFLAGS down
to the compiler and link commands, but there there were one or two
exceptions. In addition, there where a few places in "make install"
where the V=1 option was not being honored, which triggered blhc
warnings since it couldn't analyze those commands.
The e2fsck.static was the only binary that was not getting built and
packaged with the hardening flags, but I've fixed all of the blhc
warnings so in the future it will be obvious if we regress.

libext2fs: fix block iterator for extents when truncating inodes
When e2fsck uses the block iterator to release the blocks in an
extent-mapped inode, when the last block in an extent is removed, the
current extent has been removed and the extent cursor is now pointing
at the next inode. But the block iterator code doesn't know that. So
when it tries to go the next extent, it will end up skipping an
extent, and so the inode will be incompletely truncated.
The fix is to go to the next extent before calling the callback
function for the current extent. This way, regardless of whether the
current extent gets removed, the extent cursor is still pointing at
the right place.
