* Fix readonly for androidGreg Wallace2016-08-241-1/+22
| | | | | | | | | The hasmntopt() function doesn't exist in android, so it needs to be defined if we are building for android. Also, MNTOPT_RO isn't defined on android (and maybe others), so we need to manually specify if if it isn't already defined. Change-Id: I55330e37cebc087e138cdf6a0cbbe61df59f55fa

* f2fs-tools: add library version infoJaegeuk Kim2016-08-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. quoted from: http://www.gnu.org/software/libtool/manual/html_node/Updating-version-info.html#Updating-version-info Change-Id: I2226ec841157adeb65bceda06eb2e4bcafce66a4 Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

* mkfs.f2fs: support large sector sizeChao Yu2015-03-231-9/+5
| | | | | | | | | | | | | | | | | | | | | | | Since f2fs support large sector size in commit 55cf9cb63f0e "f2fs: support large sector size", block device with sector size of 512/1024/2048/4096 bytes can be supported. But mkfs.f2fs still use default sector size: 512 bytes as sector size, let's fix this issue in this patch. v2: o remove unneeded printed message when sector size is large than 512 bytes suggested by Kinglong. o show correct sector size in printed message. o use config.sectors_per_blk instead of DEFAULT_SECTORS_PER_BLOCK suggested by Kinglong. v3: o remove another unneeded printed message when sector size is large than 512 bytes suggested by Kinglong.

* mkfs.f2fs: possible endianes bug in mkfs.f2fs roll-forward speedjoerg jungermann2014-11-071-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I might found a bug in mkfs.f2fs. while experimenting with f2fs on my big endian MIPS32 device (platform lantiq, 14.07-rc3, uclibc). I ran into an issue that mkfs.f2fs, was not able to format block devices if I did not specify the sector count manually. I hunted it down to lib/libf2fs.c. After I found that the detected sector count equals to the wanted sector count shifted left (32+9) times. I found two issues: Firstly it uses ioctl BLKGETSIZE, which writes to an uint32_t the size of the device. As c->total_sectors is of type uint64_t, the value is written in to the first 4 bytes. That explained the left shift of 32 bits. Secondly BLKGETSIZE determines the size of the device in bytes (AFAIK, learned by observation). In the first branch of the if-block patched below, the c->total_sectors is calculated by c->total_sectors = stat_buf.st_size / c->sector_size; The else branch omits the devision. sector_sice is mostly 512, that explained the left shift by 9 bytes. * fixes sector count calculation * uses BLKGETSIZE64 if avail Signed-off-by: joerg jungermann <jj@borkum.net> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

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>
