* | ext4: remove duplicated block release code for extentsStefan Brüns2016-09-23-77/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | The data blocks are identical for files using traditional direct/indirect block allocation scheme and extent trees, thus this code part can be common. Only the code to deallocate the indirect blocks to record the used blocks has to be seperate, respectively the code to release extent tree index blocks. Actually the code to release the extent tree index blocks is still missing, but at least add a FIXME at the appropriate place. Signed-off-by: Stefan Brüns <stefan.bruens@rwth-aachen.de>

* | ext4: Avoid out-of-bounds access of block bitmapStefan Brüns2016-09-23-22/+12
| | | | | | | | | | | | | | | | | | | | | | | | If the blocksize is 1024, count is initialized with 1. Incrementing count by 8 will never match (count == fs->blksz * 8), and ptr may be incremented beyond the buffer end if the bitmap is filled. Add the startblock offset after the loop. Remove the second loop, as only the first iteration will be done. Signed-off-by: Stefan Brüns <stefan.bruens@rwth-aachen.de> Reviewed-by: Lukasz Majewski <l.majewski@samsung.com>
* | ext4: After completely filled group, scan next group from the beginningStefan Brüns2016-09-23-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The last free block of a block group may be in its middle. After it has been allocated, the next block group should be scanned from its beginning. The following command triggers the bad behaviour (on a blocksize 1024 fs): ./sandbox/u-boot -c 'i=0; host bind 0 ./disk.raw ; while test $i -lt 260 ; do echo $i; setexpr i $i + 1; ext4write host 0:2 0 /X${i} 0x1450; done ; ext4write host 0:2 0 /X240 0x2000 ; ' When 'X240' is extended from 5200 byte to 8192 byte, the new blocks should start from the first free block (8811), but it uses the blocks 8098-8103 and 16296-16297 -- 8103 + 1 + 8192 = 16296. This can be shown with debugfs, commands 'ffb' and 'stat X240'. Signed-off-by: Stefan Brüns <stefan.bruens@rwth-aachen.de> Reviewed-by: Lukasz Majewski <l.majewski@samsung.com>

| | | | | | | | | | | | | | | | | | | | | | Previously, only the last directory block was scanned for available space. Instead, scan all blocks back to front, and if no sufficient space is found, eventually append a new block. Blocks are only appended if the directory does not use extents or the new block would require insertion of indirect blocks, as the old code does.

* | ext4: fix possible crash on directory traversal, ignore deleted entriesStefan Brüns2016-09-23-39/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following command triggers a segfault in search_dir: ./sandbox/u-boot -c 'host bind 0 ./sandbox/test/fs/3GB.ext4.img ; ext4write host 0 0 /./foo 0x10' The following command triggers a segfault in check_filename: ./sandbox/u-boot -c 'host bind 0 ./sandbox/test/fs/3GB.ext4.img ; ext4write host 0 0 /. 0x10' "." is the first entry in the directory, thus previous_dir is NULL. The whole previous_dir block in search_dir seems to be a bad copy from check_filename(...). As the changed data is not written to disk, the statement is mostly harmless, save the possible NULL-ptr reference. Typically a file is unlinked by extending the direntlen of the previous entry. If the entry is the first entry in the directory block, it is invalidated by setting inode=0. The inode==0 case is hard to trigger without crafted filesystems. It only hits if the first entry in a directory block is deleted and later a lookup for the entry (by name) is done.
