ext4: fix duplicated mnt_drop_write call in EXT4_IOC_MOVE_EXT

ext4: don't set i_flags in EXT4_IOC_SETFLAGS

2012-06-07T23:04:19+00:00

Commit 7990696 uses the ext4_{set,clear}_inode_flags() functions to change the i_flags automatically but fails to remove the error setting of i_flags. So we still have the problem of trashing state flags. Fix this by removing the assignment. Signed-off-by: Tao Ma Signed-off-by: "Theodore Ts'o" Cc: stable@kernel.org

ext4: don't trash state flags in EXT4_IOC_SETFLAGS

2012-06-01T03:46:01+00:00

In commit 353eb83c we removed i_state_flags with 64-bit longs, But when handling the EXT4_IOC_SETFLAGS ioctl, we replace i_flags directly, which trashes the state flags which are stored in the high 32-bits of i_flags on 64-bit platforms. So use the the ext4_{set,clear}_inode_flags() functions which use atomic bit manipulation functions instead. Reported-by: Tao Ma Signed-off-by: "Theodore Ts'o" Cc: stable@kernel.org

ext4: calculate and verify inode checksums

2012-04-29T22:31:10+00:00

This patch introduces to ext4 the ability to calculate and verify inode checksums. This requires the use of a new ro compatibility flag and some accompanying e2fsprogs patches to provide the relevant features in tune2fs and e2fsck. The inode generation changes have been integrated into this patch. Signed-off-by: Darrick J. Wong Signed-off-by: "Theodore Ts'o"

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

2012-01-09T12:52:10+00:00

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.

ext4: add missing ext4_resize_end on error paths

2012-01-04T22:09:52+00:00

Online resize ioctls 'EXT4_IOC_GROUP_EXTEND' and 'EXT4_IOC_GROUP_ADD' call ext4_resize_begin() to check permissions and to set the EXT4_RESIZING bit lock, they do their work and they must finish with ext4_resize_end() which calls clear_bit_unlock() to unlock and to avoid -EBUSY errors for the next resize operations. This patch adds the missing ext4_resize_end() calls on error paths. Patch tested. Cc: stable@vger.kernel.org Signed-off-by: Djalal Harouni Signed-off-by: "Theodore Ts'o"

ext4: add new online resize interface

2012-01-04T22:09:44+00:00

This patch adds new online resize interface, whose input argument is a 64-bit integer indicating how many blocks there are in the resized fs. In new resize impelmentation, all work like allocating group tables are done by kernel side, so the new resize interface can support flex_bg feature and prepares ground for suppoting resize with features like bigalloc and exclude bitmap. Besides these, user-space tools just passes in the new number of blocks. We delay initializing the bitmaps and inode tables of added groups if possible and add multi groups (a flex groups) each time, so new resize is very fast like mkfs.
