AC_PREREQ([2.68])
Unify version and date management 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 Signed-off-by: Sven-Göran Bergh <sgb@systemasis.org> Signed-off-by: Jaegeuk Kim <jaegeuk.kim@samsung.com>

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 dump.f2fs Signed-off-by: Changman Lee <cm224.lee@samsung.com> Signed-off-by: Byoung Geun Kim <bgbg.kim@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk.kim@samsung.com>
