f2fs-tools fails to cross build from source, because its upstream
build system wrongly uses AC_CHECK_FILE. The purpose of the macro is
checking for files on the host system. However here it is used to
check whether a .git directory exists, which is a property of the
build place. A simple "test -d" should be used here. After doing so,
f2fs-tools cross builds successfully.

This allows the development link libraries to be installed in
/usr/lib, while the run-libraries are installed in /lib, which is
required by Debian policy. This can be done via:
configure --prefix=/ --libdir=/usr/lib --with-root-libdir=/lib
The technique of working around libtool's inflexibility is borrowed
from util-linux.

This patch gives the version info for two libraries.
mkfs/libf2fs_format.la
lib/libf2fs.la
The versioning rule should be:
1. Start with version information of '0:0:0' for each libtool library.
2. Update the version information only immediately before a public release of
your software. More frequent updates are unnecessary, and only guarantee
that the current interface number gets larger faster.
2. If the library source code has changed at all since the last update, then
increment revision (c:r:a) becomes (c:r+1:a).
3. If any interfaces have been added, removed, or changed since the last update,
increment current, and set revision to 0.
4. If any interfaces have been added since the last public release, then
increment age.
5. If any interfaces have been removed or changed since the last public release,
then set age to 0.

The current build system fails to `make distcheck` correctly
for two reasons: 1) Some header files are not listed in the
source files for fsck.f2fs and mkfs.f2fs, and so don't make it
into the dist tarball. 2) By setting a default prefix in
configure.ac, the mock install doesn't add the correct prefix
and instead tries to install directly to the file system.
This patch corrects those problems and also adds an autogen.sh
script for convenience.

fsck.f2fs checks file system consistency, but does not repair a broken
file system yet.
dump.f2fs shows the information of a specific inode and makes dump file
of SSA and SIT.
f2fs checks file system consistency as follows:
o When data about used area and its metadata are identical,
f2fs is considered consistent. To verify such consistency, we use
three bitmaps: nat_area_bitmap, sit_area_bitmap, and main_area_bitmap.
First, each bit in nat_area_bitmap corresponds to a nid in NAT.
Second, each bit in sit_area_bitmap corresponds to a valid block in a
segment. This bitmap is same to the total valid_map of f2fs_sit_entries
in SIT.
Last, each bit in main_area_bitmap corresponds to a block in main area
except meta area.
After a consistency check of each block, we set or clear the
corresponding bit of each bitmap.
From the root node, we start consistency check. The verified
information varies according to block type.
1. NODE
- Read information of node block from NAT
- Check if block address is allocated using node info.
- Check if the type of f2fs_summary related to nid in SSA is NODE.
- Update the corresponding bit in nat_area_bitmap.
- Update the corresponding bit in sit_area_bitmap.
- Set the corresponding bit in main_area_bitmap to 1.
- Then, read node block. According to its attribute, explore
inode/direct node/indirect node/double indirect node
recursively.
- If it is an inode block, we also check its xattr and hard link.
2. DATA
- Check if the type of f2fs_summary related to nid in SSA is DATA.
- Set the corresponding bits of sit_area_bitmap and
main_area_bitmap to visited
- If it is a dentry block, traverse each dentries that may be
regular
file or directory. At this time, it will check inode block again.
Finally, we verify whether
- every nat_area_bitmap is visited
- any unreachable hard link exists
- values of sit_area_bitmap and main_area_bitmap are identical
- total_valid_block_count/node_count/inode_count are correct
Usage:
o fsck.f2fs
# fsck.f2fs /dev/sdx
options:
-d debug level [default:0]
o dump.f2fs
# dump.f2fs -i [ino] /dev/sdx
# dump.f2fs -s 0~-1 /dev/sdx (SIT dump)
# dump.f2fs -a 0~-1 /dev/sdx (SSA dump)
options:
-d debug level [default:0]
-i inode no (hex)
-s [SIT dump segno from #1~#2 (decimal), for all 0~-1]
-a [SSA dump segno from #1~#2 (decimal), for all 0~-1]
Note: To use dump.f2fs, please run make install or ln -s fsck.f2fs

Patch 1:
Now we have two different versions that produce different superblocks/
filesystems with the same version info. Major/minor version in the sb
should reflect the version of the tool creating the filesystem. This
patch will ensure that the version entered in the file VERSION will
be used consistently throughout the code.
Patch 2:
In order to simplify the maintenance with a new release the date
in F2FS_TOOLS_DATE is now take from the last commit in git. Thus,
git is needed to run autoconf. However, git is not needed for the
simple build procedure, ./configure && make, that should be the
only things needed to build the tool from a tar.gz package.
Pros & Cons:
[+] Automated
[+] True
[-] Git needed to run autoreconf
Change log by Jaegeuk from the initial patch-set:
- Merge two patches into one
: Eliminate the intermediate state having version.h and VERSION.
- Remove the Git dependency which is one of Cons
: If there is no git tree, just use DATE described in VERSION.
- Minor coding style
Pros & Cons:
[+] Automated
[+] True
[+] No Git dependency
