ext3: Fix fdatasync() for files with only i_size changes

2012-09-14T17:00:32Z

commit 156bddd8e505b295540f3ca0e27dda68cb0d49aa upstream. Code tracking when transaction needs to be committed on fdatasync(2) forgets to handle a situation when only inode's i_size is changed. Thus in such situations fdatasync(2) doesn't force transaction with new i_size to disk and that can result in wrong i_size after a crash. Fix the issue by updating inode's i_datasync_tid whenever its size is updated. Reported-by: Kristian Nielsen Signed-off-by: Jan Kara Signed-off-by: Greg Kroah-Hartman

ext3: fix start and len arguments handling in ext3_trim_fs()

2012-03-02T16:47:40Z

The overflow might happen when passing blocknr into ext3_get_group_no_and_offset(), because it expects type ext3_fsblk_t which might be smaller than uint64_t. This will most likely happen when calling FITRIM with the default argument len = ULLONG_MAX. Fix this by using "end" variable instead of "start+len" as it is easier to get right and specifically check that the end is not beyond the end of the file system, so we are sure that the result of get_group_no_and_offset() will not overflow. Otherwise truncate it to the size of the file system. Signed-off-by: Lukas Czerner Cc: Jan Kara Signed-off-by: Jan Kara

ext3: Update ctime in ext3_splice_branch() only when needed

2012-02-29T20:53:46Z

Currently ext3 updates ctime in ext3_splice_branch() which is called whenever we allocate one block. But it is wasteful because ext3 doesn't support nanosecond timestamp. This leads to a performance loss. Signed-off-by: Kazuya Mio Signed-off-by: Jan Kara

ext3: Don't call dquot_free_block() if we don't update anything

2012-02-29T20:53:46Z

dquot_free_block() is called in the end of ext3_new_blocks() and updates information of the inode structure. However, this update is not necessary if the number of blocks we requested is equal to the number of allocated blocks. Signed-off-by: Kazuya Mio Signed-off-by: Jan Kara

ext2/3/4: delete unneeded includes of module.h

2012-01-09T12:52:10Z

Delete any instances of include module.h that were not strictly required. In the case of ext2, the declaration of MODULE_LICENSE etc. were in inode.c but the module_init/exit were in super.c, so relocate the MODULE_LICENCE/AUTHOR block to super.c which makes it consistent with ext3 and ext4 at the same time.

ext{3,4}: Fix potential race when setversion ioctl updates inode

2012-01-09T12:52:10Z

The EXT{3,4}_IOC_SETVERSION ioctl() updates i_ctime and i_generation without i_mutex. This can lead to a race with the other operations that update i_ctime. This is not a big issue but let's make the ioctl consistent with how we handle e.g. other timestamp updates and use i_mutex to protect inode changes.
