dump.f2fs: show checkpoint flag
This patch is to show the checkpoint flag.
With this flag, we can guess the last status of the partition.
And, this can be used by xfstests.

f2fs: rearrange options to remove redundant check
This patch summarizes the usage of options.
-a : auto_fix, fix corruption, only if f2fs reported some potential errors
-f : force, fix corruption entire partition
None : prompt, if fsck.f2fs detets any corruption

fsck.f2fs: add auto_fix feature
This patch adds an auto_fix feature which fixes inconsistency of f2fs images.
E.g.,
With this option, -a, fsck.f2fs tries to fix inconsistency only if its valid
checkpoint has CP_FSCK_FLAG, written by previous bug_on cases.
So, normally it does fix nothing, so that there is no performance regression.
But, if a sort of corruption was reported by the f2fs module, this tries to
fix potential corrupted partition.

libf2fs: check more conditions on mounted filesystem
In the case of lazy umount, "umount -l", some processes are able to use the
file system even if its mountpoint was disconnected.
At this moment, we should not allow mkfs.f2fs.
This patch adds this condition check.

f2fs-tools: add fsck.f2fs and dump.f2fs
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
