* btrfs-progs: convert-tests: Add test for backup superblock migrationQu Wenruo2016-06-01
| | | | | | | | | | | | | | New convert framework uses new and simpler chunk layout, while the cost is the more complex superblock range migration logical, compared to old convert. Enhance the convert test script to create file which will takes up 2nd backup superblock space, to ensure the superblock migration is working as expected.

* btrfs-progs: make btrfs-image restore to support dupLu Fengqi2016-06-01
| | | | | | | | | | | | | | Previously btrfs-image restore would set the chunk items to have 1 stripe, even if the chunk is dup. If you use btrfsck on the restored file system, some dev_extent will not find any relative chunk stripe, and the bytes-used of dev_item will not equal to the dev_extents's total_bytes. This patch store a additional physical just for the dup case when build the in-memory chunk-tree. Currently btrfsck on the restored file system, only single and dup is no problem. raid* support should be added in the future.

* btrfs-progs: Return earlier for previous itemQu Wenruo2016-06-01
| | | | | | | | | | | | | | Follow kernel code to return earlier for btrfs_previous_item() function. Before this patch, btrfs_previous_item() doesn't use its min_objectid to exit, this makes caller to check key to exit, and if caller doesn't check, it will iterate all previous item. This patch will check min_objectid and type, to early return and save some time. Signed-off-by: Qu Wenruo <quwenruo@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.com>

* btrfs-progs: udev: add rules for dm devicesJeff Mahoney2016-06-01
| | | | | | | | | | | | | | | | | | | | | Systemd's btrfs rule runs btrfs dev ready on each device as it's discovered. The btrfs command is executed as a builtin command via an IMPORT{builtin} rule, which means it gets executed at rule evaluation time, not rule execution time. That means that the device mapper links haven't been setup yet and the only nodes that can be depended upon are /dev/dm-#. That we see /dev/mapper/name names in /proc/mounts is only because we replace the device name we have cached with the one passed in via mount. If we have a multi-device file system and the primary device is removed, the remaining devices will show /dev/dm-#. In addition, if the udev rule is executed again by someone generating a change event (e.g. partprobe), the names are also replaced by the /dev/dm-# names. This patch adds a new rule that adds a run rule that calls btrfs dev ready again using the device mapper links once they're created.

* btrfs-progs: add validation checks for chunk loadingLiu Bo2016-05-11
| | | | | | | | | | | | | | | | | To survive fuzz filesystem images, we need various validation checks to make btrfsck detect any invalid value inside chunks including those in sys_array. Note that these checks may not be sufficient to cover all corner cases, we may need to add more later. This also refractor previous various checks into a helper function so that we can add more checks into it in the future.
